Detailed Description

Represents the scenario currently being portrayed.

A scenario is loaded from disc and contains characters, geometry, appearances, scripts, minds, paths, waypoints, scripts, signals, sounds, groups, crowds, regions, cameras, fog, lights, variables, callbacks, and the octtree.

All these items and their interactions are the raison d'être for DI-Guy, so diguyScenario is an important class to understand. It provides facilities for loading, adding, removing, and configuring the objects mentioned above, and for managing the flow of time, sending messages, triggering scripts, and testing for collisions with the geometry. There are many other features, as well.

Member Enumeration Documentation

anonymous enum

This is an enumeration of the different callbacks that can be registered with add_callback() and add_callback_script().

Callbacks return a value of type diguyCallbackReturn, which will be DIGUY_CALLBACK_STOP or DIGUY_CALLBACK_CONTINUE. If the callback returns DIGUY_CALLBACK_STOP, the default handler of the function will not be called; the callback is asserting that it has done everything necessary for the function call. If the callback returns DIGUY_CALLBACK_CONTINUE, the default handler for the function will be called after the callback.

Callback Enums:

CALLBACK_ID_CREATE

 This callback will be called when a new scenario is created.
 It should only be used by
 diguyApp::add_default_scenario_callback().  Using it in
 set_callback() will have no effect, as by that time the
 scenario has already been created.

CALLBACK_ID_RESET

 This callback will be called when the scenario is reset.

CALLBACK_ID_WAIT_CURSOR_SHOW

 This callback will be called when a diguy operation
 is likely to take some time, allowing an application to
 display a wait cursor.

CALLBACK_ID_WAIT_CURSOR_HIDE

 This callback will be called when a diguy operation
 that caused a wait cursor to be shown has completed,
 allowing an application to hide the wait cursor.

CALLBACK_ID_LOAD

 This callback will be called when a scenario is loaded, thereby
 giving a chance for custom code to read extra elements from the
 loaded file.

CALLBACK_ID_SAVE

 This callback will be called when a scenario is saved, thereby
 giving a chance for custom code to insert extra elements into the
 saved file.

CALLBACK_ID_LOAD_SCENARIO_FILE

 This callback will be called just before a scenario loads
 a new file.

CALLBACK_ID_SAVE_SCENARIO_FILE

 This callback will be called just after a scenario saves
 a new file. With a char * pointer to the file name.

CALLBACK_ID_MANUALLY_INVOKED

 This callback id will be supplied to event handlers invoked
 by a call to manually_invoke_event_handler().

 The user's returned diguyCallbackReturn value will be ignored.

CALLBACK_ID_POST_DRAW

 This callback will be called just after a scenario finishes it's
 draw commands. The diguyViewPainter class can be used to issue
 abstract draw commands in DI-Guy Scenario.

Lua Example:

local painter = this_app:get_view_painter();
painter:set_pen_color(1,1,0);
painter:draw_line(0,0,0, 1,1,1);

CALLBACK_ID_PLAYBACK_MODE_CHANGED

 This callback will be called when the playback mode of the
 scenario has changed.  For example, the Play or Stop buttons are
 pressed in DI-Guy Scenario, or set_playback_mode() is called.

 The user's returned diguyCallbackReturn value will be ignored.

CALLBACK_ID_INPUT_MODE_CHANGED

 This callback will be called when the input mode of the
 scenario has changed.  For example, when an Input Mode button is
 pressed in DI-Guy Scenario, or diguyApp::set_base_input_mode()
 is called.

 The user's returned diguyCallbackReturn value will be ignored.

CALLBACK_ID_RENDER_MODE_CHANGED

 This callback will be called if the render mode of the scenario
 changes, typically due to a set_current_render_mode().

 The user's returned diguyCallbackReturn value will be ignored.

CALLBACK_ID_POST_LOAD_CHECKPOINT

 This callback will be called just after a scenario finishes
 loading a checkpoint file.

Constructor & Destructor Documentation

diguyScenario::diguyScenario ( bdiScenario *  scenario )

private

A private constructor.

Use the DI-Guy function diguy_create_scenario() to obtain a diguyScenario object pointer.

virtual diguyScenario::~diguyScenario ( )

privatevirtual

A private destructor.

Use the DI-Guy function diguy_destroy_scenario() to delete a diguyScenario object pointer.

Member Function Documentation

static diguyScenario* diguyScenario::get_current_scenario ( )

static

This static function returns a pointer to the current scenario object.

All functions below can then be called through this pointer. This is the same pointer returned by the call diguy_create_scenario().

lua scripts get the current scenario through the variable this_scenario.

Returns:

a pointer of type diguyScenario

C++ Example:

diguyScenario* sc = diguyScenario::get_current_scenario();
sc->reset();

Lua Example:

this_scenario:reset();

const char* diguyScenario::get_name

(

)

Returns the name of the object.

This pointer will never be NULL.

Returns:

name of the object

const char* diguyScenario::get_type_name

(

)

Returns the type name of the object.

This pointer will never be NULL.

Returns:

type name of the object

const char* diguyScenario::get_description

(

)

Returns: the scenario description as specified in the scenario info page.

int diguyScenario::update

(

float

t

)

Sets the desired simulation time of the scenario.

Some update operations will use the simulation desired time directly.

Many other scenario operations – notably character position and pose updates – will not happen until the desired t passes each subsequent tick dt threshold. See set_tick_dt().

This function sets both elapsed simulation time and elapsed realtime to the same value. This is usually desired in DI-Guy applications. To pass separate values for simulation time and realtime time, call update2().

Time can be run backwards. This happens if the passed t is lower than any t previously passed to the update() function; the scenario remembers the highest t it has reached. If t is set to less that the highest t reached, characters that have history data will replay what they were doing at the specified time. Characters that do not have history will remain motionless until t advances past the previous highest t.

Scenario time will never go below 0.

If t reaches the scenario tout ("T Out") time (as set by set_tout(), a number of things may happen. The scenario may:

• simply stop at the tout time
• continue past the tout time
• rewind to time 0 and play back recorded history

• reset and re-simulate the scenario from time 0

  The default tout time is 60000 for DI-Guy applications. The tout can be enabled and disabled with set_tout_enabled().

  This function cannot explicitly be called for DI-Guy Scenario, but the effects of t reaching tout during scenario simulation are outlined here anyway.

For a DI-Guy application:

• If the scenario tout is enabled the scenario will stop.

• If the scenario tout is disabled the scenario will continue indefinitely, regardless of scenario tout.

  Note that no playback looping happens in a DI-Guy application if tout is reached. Only in DI-Guy Scenario does the loop flag have an effect.

For DI-Guy Scenario:

• If the loop flag is not set (see set_playback_loop()) or a movie is being recorded, the scenario will stop.
• If the loop flag is set, and any character in the scenario has history data (see the History Functions for diguyCharacter), the scenario will be rewound to 0 and play back history data.
• If the loop flag is set, but no characters in the scenario have history data, the scenario will be reset to 0 and re-simulate from there.

Parameters

t	desired time in seconds

Returns:

0 on success, -1 on failure

Callable From:

• C++

int diguyScenario::update2	(	float	t,
		float	realtime_t
	)

Similar to update(), but the realtime time can be explicitly passed in.

Parameters

t	desired simulation time in seconds
realtime_t	elapsed real time in seconds

Returns:

0 on success, -1 on failure

Callable From:

• C++

int diguyScenario::set_playback_loop

(

int

playback_loop

)

This function sets whether the scenario is designed to loop at tout.

The default is for scenarios to loop.

Note that this has an effect only in DI-Guy Scenario. DI-Guy applications do not use this flag.

See get_playback_loop().

Parameters

playback_loop

pass 1 to have scenario loop at tout, 0 to not

Returns:

0 on success, -1 on failure

Callable From:

• C++

int diguyScenario::set_tick_dt

(

float

tick_dt

)

Scenarios progress at discrete time steps, called "ticks".

Each tick is of the same duration. This function sets the amount of time each tick takes.

Because changing the tick interval of a scenario changes when event beads occur, any change may introduce subtle differences in scenario playback.

Note that loading a .dss file will change the tick dt, as tick dt is set on a per scenario basis.

The default tick dt of a new scenario is 0.03125 seconds, or 32 frames per second.

Parameters

tick_dt

duration, in seconds, of each scenario tick

Returns:

0 on success, -1 on failure

Callable From:

• C++

C++ Example:

diguyScenario* sc = diguy_create_scenario();
if (sc)
{
        sc->load("my_scenario.dss");
        sc->set_tick_dt(0.033333);   // 30 fps
}

float diguyScenario::get_t

(

)

This function returns the time in seconds that the scenario is currently at.

See update().

Note that this value will not necessarily track the t passed in the update() function. This t advances only when the scenario's current tick changes. See set_tick_dt() and update().

Returns:

current time in seconds

float diguyScenario::get_realtime_t

(

)

This function returns the realtime time in seconds that the scenario is currently at.

This may be different than get_desired_t() if the scenario is stopped or the time passed in update() is not tracking realtime.

Returns:

current time in seconds

float diguyScenario::get_desired_t

(

)

This function returns the desired time in seconds that the scenario is currently at.

This may be different than get_t(), which advances only when the scenario's current tick changes.

Returns:

current time in seconds

int diguyScenario::set_tout

(

float

tout

)

This function sets the tout ("T Out") time of the scenario.

What will happen when the scenario reaches this time depends on a number of factors. See update() for more information.

Returns:

0 on success, -1 on failure

Callable From:

• C++

float diguyScenario::get_tout

(

)

This function returns the tout time of the scenario.

This is the time at which a scenario is designed to end.

See set_tout() and update().

Returns:

tout of scenario

void diguyScenario::set_tout_enabled

(

int

tout_enabled

)

This function sets what will happen when the scenario reaches its tout time.

If set to 0, the scenario will ignore the tout time and continue indefinitely.

See update() for more information.

int diguyScenario::get_tout_enabled

(

)

This function returns the whether tout is enabled.

See set_tout_enabled() and update().

Returns:

1 if tout enabled, 0 if not

int diguyScenario::get_playback_loop

(

)

This function returns whether the scenario is designed to loop when the scenario's tout time is reached.

See update() for more information about looping.

Returns:

0 if no loop desired; 1 if loop desired

float diguyScenario::get_tick_dt

(

)

This function returns the most recent setting of set_tick_dt().

int diguyScenario::get_ticks_can_be_dropped

(

)

Returns: This function returns the most recent setting of set_ticks_can_be_dropped().

void diguyScenario::set_ticks_can_be_dropped

(

int

ticks_can_be_dropped

)

This function sets whether a scenario can "drop" ticks in order to catch up if it falls behind.

Scenario updates progress in discrete time steps called ticks (see set_tick_dt() and update()). If the difference in times specified in subsequent calls to update() is greater than the tick dt, which can happen if calls to update() are taking too long because the scenario is too complex or if the caller is attempting to "fast forward" to a particular time in the scenario, the scenario may skip processing of intermediate ticks in order to catch up.

The scenario will not consider itself behind until the number of ticks covered by a particular call to update() is equal to or greater than the value set by set_max_ticks_behind_until_drop().

Dropping ticks, while it improves performance, may have unintended side effects, including:

• event beads of characters on paths that fall on the dropped ticks – including aim beads, decision beads, gaze beads, and script beads – will not be evaluated and will therefore have no effect on the scenario

• review playback of characters (see diguyCharacter::set_history_type()) over the dropped intervals will be choppy

  Not dropping ticks also has potential side effects:

• if a scenario is falling behind more and more on each call to update(), it may never be able to catch up and performance of DI-Guy will increasingly degrade

  The default setting is that ticks can be dropped.

Parameters

ticks_can_be_dropped

pass 1 for ticks to be dropped; else pass 0

long diguyScenario::get_max_ticks_behind_until_drop

(

)

Returns: This function returns the most recent setting of set_max_ticks_behind_until_drop().

void diguyScenario::set_max_ticks_behind_until_drop

(

long

max_ticks_behind_until_drop

)

This function sets how many ticks a scenario must be behind before it starts dropping ticks in order to catch up.

For a discussion of how a scenario may fall behind, see set_ticks_can_be_dropped().

Note that if ticks cannot be dropped, (e.g., 0 is passed to set_ticks_can_be_dropped()) this function will have no effect.

The default value is 0 in the DI-Guy SDK, In DI-Guy Scenario it is 2.

Parameters

max_ticks_behind_until_drop

how many ticks a scenario must be behind until it drops ticks

int diguyScenario::set_playback_mode

(

diguyScenarioPlaybackMode

playback_mode

diguyScenarioPlaybackMode diguyScenario::get_playback_mode

(

)

Returns: current playback mode as set by set_playback_mode() or the DI-Guy Scenario user interface.

float diguyScenario::derive_playback_mode_dt

(

float

dt_in

)

This function derives a dt based on an input dt (usually derived from change in realtime from previous to current frame) and the scenario's current playback mode.

The resulting dt can then be used to advance the time passed to diguyScenario::update() so that it emulates the effect of the VCR buttons in DI-Guy Scenario.

This function does not change the scenario's current time or playback mode.

Examples based on a dt_in of 0.03 seconds:

• DIGUY_SCENARIO_PLAYBACK_MODE_STOP: derived_dt = 0.0
• DIGUY_SCENARIO_PLAYBACK_MODE_PLAY: derived_dt = 0.03
• DIGUY_SCENARIO_PLAYBACK_MODE_PLAY_REVERSE: derived_dt = -0.03
• DIGUY_SCENARIO_PLAYBACK_MODE_FF: derived_dt = 0.12
• DIGUY_SCENARIO_PLAYBACK_MODE_FF_REVERSE: derived_dt = -0.12
• DIGUY_SCENARIO_PLAYBACK_MODE_SS: derived_dt = frame dt
• DIGUY_SCENARIO_PLAYBACK_MODE_SS_REVERSE: derived_dt = - frame dt
• DIGUY_SCENARIO_PLAYBACK_MODE_REWIND: derived_dt = - scenario t

Note that the playback mode should be set to DIGUY_SCENARIO_PLAYBACK_MODE_STOP after time advances in either of the single step ("SS") modes or the rewind mode.

Parameters

dt_in

delta time in seconds from advancing simulation time

int diguyScenario::reset

(

)

This function resets all scenario characters, signals, variables, and all other scenario objects to their original state.

Scenario time will be set to 0.

Returns:

0 on success, -1 on failure

int diguyScenario::load

(

const char *

filename

)

This function loads the specified scenario.

Any previously loaded scenario objects will be deleted. To merge a scenario into the existing scenario (load without deleting existing objects), use the call merge().

The passed filename can be either a ".dss" file, which is a DI-Guy Scenario file, or a ".dsr" file, which is a DI-Guy Review file.

Once the file has been loaded an implicit reset() will occur.

Parameters

filename

filename of scenario to be loaded

Returns:

0 on success, -1 on failure

Callable From:

• C++

int diguyScenario::save

(

)

Saves the scenario into its current filename.

This filename will be the most recent of:

• the filename used in a load() function call

• the filename used in a save_as() function call

  The filename that will be used can be retrieved using the get_filename() or get_filename_without_directory() functions.

  Once saved the "unsaved" flag (as returned by get_unsaved()) will be set to 0.

Returns:

0 on success, -1 on failure

Callable From:

• C++

int diguyScenario::save_as

(

const char *

filename

)

Similar to save(), but new filename is specified by the filename argument.

Parameters

filename

new filename of scenario

Returns:

0 on success, -1 on failure

Callable From:

• C++

const char* diguyScenario::get_filename

(

)

Returns the most recent of:

• the filename used in a save_as() function call

Returns:

filename of saved scenario

Callable From:

• C++

const char* diguyScenario::get_filename_without_directory

(

)

Similar to get_filename(), but with any leading directories removed.

Callable From:

• C++

int diguyScenario::get_unsaved

(

)

Returns: 1 if scenario has been modified since save or load, else 0.

Callable From:

• C++

void diguyScenario::set_unsaved

(

int

unsaved

)

Manually sets the "unsaved" flag to the passed value.

Parameters

unsaved

new unsaved status; 1 for unsaved, 0 for saved

Callable From:

• C++

int diguyScenario::draw

(

)

This function draws all visible elements of the loaded scenario in immediate mode graphics environments (see below).

This is the equivalent of calling draw_pass1(), immediately followed by draw_pass2(), immediately followed by post_draw().

Note that any character graphics culling, far position rendering, etc., depend on the render camera set by the set_render_camera() function. A render camera does not always need to be set; see set_render_camera() for more details.

Returns:

0 on success, -1 on failure

OpenGL Version:

This function immediately draws all scenario elements. Either this function, or draw_pass1(), draw_pass2(), and post_draw(), should be called once per frame.

int diguyScenario::draw_pass1

(

)

This function, along with draw_pass2(), allows the drawing of opaque and transparent polygons to be separated.

This function draws all opaque polygons.

Returns:

0 on success, -1 on failure

OpenGL Version:

This function immediately draws the opaque scenario elements. Either this function or draw() should be called once per frame.

int diguyScenario::draw_pass2

(

int

also_call_post_draw = 1

)

Same as draw_pass1(), but draws transparent scenario elements.

The also_call_post_draw argument is set to 1 for backwards compatibility.

int diguyScenario::draw_particles

(

)

Explicitly invokes particle drawing code, this can be useful for retained mode renderers that have chosen to hook up our immediate mode particle system as a post draw stage (osg)

void diguyScenario::pre_draw_cull_state_reset

(

)

Clears all the culling bits state for various characters, this should be called before any drawing is done.

It allows for multiple draw passes culling state info to get accumulated together. This is needed to efficiently avoiding updating graphics classes for characters that are out of all rendering viewports. If a character is generally visible we will update it's state with our multi-threaded pipeline. If it's not visible. then we won't update it until it's actually drawn. In retained mode renderers diguyCharacter::set_is_culled(0) must be set for each character that is drawn so that we know to update it's state in the faster manor.

void diguyScenario::post_draw_cull_state_save

(

)

Saves all the culling bits for various characters, should be called after all drawing is done so that the next call to update() has reasonable culling information to work with.

See pre_draw_cull_state_reset() for more information about graphics update culling.

void diguyScenario::calculate_character_lods

(

)

This function updates all character lods and updates the instancing system representation of the characters calling this is needed for the instancing system to work.

int diguyScenario::post_draw	(	int	call_plugins_post_draw = 1,
		int	call_lua_packages_draw = 1,
		int	call_post_draw_callback = 1
	)

This function draws visual elements that must be drawn after the main render has been done.

Note that this function is called automatically by the draw() call. Only call this function if draw() is not called; e.g., if draw_pass1() and draw_pass2() are used.

This function can be called from scene graph type renderers which typically don't need or want to have the draw() function called.

Parameters

call_plugins_post_draw	pass 1 to call plugin post_draw() functions
call_lua_packages_draw	pass 1 to call lua package draw functions
call_post_draw_callback	pass 1 to invoke callbacks with callback id CALLBACK_ID_POST_DRAW

Returns:

0 on success, -1 on failure

int diguyScenario::set_graphics_attach_ptr

(

void *

graphics_attach_ptr

)

This function sets the attachment point that to be used for graphics created by the library.

Parameters

graphics_attach_ptr

this is a pointer to a group-type object; the specific type is dependent on graphics environment

Returns:

0 on success, -1 on failure

OpenGL Version:

This function does not have any effect.

Direct3D Version:

The passed pointer should be a LPDIRECT3DRMFRAME2.

LPDIRECT3DRMFRAME2 attach_frame = get_scene_frame();
scenario->set_graphics_attach_ptr(attach_frame);

diguyScenarioMergeSettings* diguyScenario::create_merge_settings

(

diguyScenarioMergeInitialSettings

initial_settings = DIGUY_MERGE_INITIAL_SETTINGS_DEFAULT

)

This function creates a merge settings object.

This object can allow for fine control over which elements in a scenario are merged during a merge() call, and what to do if there is a collision with an existing element.

Once the initial settings are made based on the initial_settings argument, the settings can be fine-tuned by calling member functions of the diguyScenarioMergeSettings object.

Destroy the object with a call to destroy_merge_settings().

Parameters

initial_settings

what the initial settings should be when the object is created

This function destroys a merge settings object created by a call to create_merge_settings().

int diguyScenario::merge	(	const char *	filename,
		diguyScenarioMergeSettings *	merge_settings = NULL
	)

This function merges the specified scenario.

Any previously loaded scenario elements will be retained, depending on settings in the merge_settings argument.

Parameters

filename	filename of scenario to be merged
merge_settings	object that controls how elements are merged; pass NULL for default merge handling

Returns:

0 on success, -1 on failure

int diguyScenario::merge_object

(

const char *

string

)

This function performs a "micro merge", allowing a scenario to merge in the contents of a text string representing a single object.

On example of use is for a Lua Package to contain a number of text strings representing particle systems or sounds that an agent need will need. When needed objects in text form can be merged into the scenario using this function.

The DI-Guy Scenario Particle System page has a "Display Object Text" button that can display the object text of a particle system that is appropriate for use by this function. Other object pages that have this button are Sound, Formation, and Crowd Profile.

Text can also be taken directly from .dss files.

See also the diguyCharacter::merge_object() function.

**

Note

the parser is very sensitive to tabs and formatting!

int diguyScenario::include_object_library

(

const char *

library_name

)

This function makes the objects in the specified library available for use in the scenario.

Object libraries allow new content to be created in one scenario and automatically shared to other scenarios. When including a library, objects that are already in the scenario are preserved.

A library with specified name must be available for inclusion. Object libraries are located in the $DIGUY/config/diguy/object_libraries and $DIGUY/custom/config/diguy/object_libraries directories. The filename for the library must be "library_[libname].cfg".

Available object libraries in these directories will automatically be detected by the scenario, but objects in the libraries will not be included in the scenario until this function is called.

For example, if the objects in the file "library_crowd_sounds.cfg" should be made available in the scenario, the library name "crowd_sounds" should be passed into this function.

Currently the following object types can be in libraries:

• particle system
• formation
• crowd profile
• sound

Parameters

library_name

name of library

Returns:

0 on success, -1 on failure

int diguyScenario::uninclude_object_library

(

const char *

library_name

)

This function is the opposite of include_object_library().

Objects in the named library are made unavailable to the scenario.

Parameters

library_name

name of library

Returns:

0 on success, -1 on failure

void diguyScenario::set_base_datetime	(	int	year = -1,
		int	month = -1,
		int	day = -1,
		int	hour = -1,
		int	minute = -1,
		int	second = -1,
		int	msec = -1
	)

This function will set what the current datetime will be when the scanario is reset.

Pass -1 for values that should be set based on current datetime.

Note that if set_base_datetime_default_to_now() and set_base_datetime_default_to_today() can override these values.

void diguyScenario::set_base_datetime	(	const char *	datetime_string,
		const char *	format
	)

Similar to set_base_datetime(), but datetime is stored in the passed string, formatted in the passed format string.

void diguyScenario::get_base_datetime	(	int *	year = NULL,
		int *	month = NULL,
		int *	day = NULL,
		int *	hour = NULL,

		int *	msec = NULL
	)

Retrieves the base datetime.

Pass NULL for arguments that aren't needed.

void diguyScenario::set_base_datetime_default_to_now

(

int

to_now

)

Setting this value to 1 will cause the time part of the datetime to be set to whatever "real" time it is when reset() is called, instead of the time stored in the base datetime as set by set_base_datetime().

For example, if it is 10:30 AM in "real time" when the scenario is reset, the current time will be set to 10:30:00:000 on reset.

Setting this value to 0 will restore the default behavior.

int diguyScenario::get_base_datetime_default_to_now

(

)

Returns: 1 if the current time will be set to the "real time" on reset, 0 is not.

void diguyScenario::set_base_datetime_default_to_today

(

int

to_today

)

Similar to set_base_datetime_default_to_now(), but for the date part of the datetime.

int diguyScenario::get_base_datetime_default_to_today

(

)

Returns: 1 if the current date will be set to the "real date" on reset, 0 is not.

void diguyScenario::set_current_datetime	(	int	year = -1,
		int	month = -1,
		int	day = -1,
		int	hour = -1,
		int	minute = -1,
		int	second = -1,
		int	msec = -1
	)

Allows current datetime to be explicitly set.

Note that in most cases the current datetime should be set by the base datetime plus how much time has advanced in the scenario.

This function can be useful if the datetime needs to be syncronized with that from another source, say, from network exercise data.

void diguyScenario::set_current_datetime	(	const char *	datetime_string,
		const char *	format
	)

Similar to set_current_datetime(), but datetime is stored in the passed string, formatted in the passed format string.

The function preload_character_type() should be called at the beginning of a scenario in which this call will be made to avoid a hitch in frame rate.

See also retrieve_character_from_recycle_bin() for a potentially faster way of creating a character.

Parameters

name	name of the new character
character_type	character's type
appearance	base appearance of character; pass NULL to use default appearance
hand_item	hand item appearance; pass NULL to use default appearance

Returns:

pointer of type diguyCharacter; NULL if creation failed

diguyCharacter* diguyScenario::create_temporary_character	(	const char *	name,
		const char *	character_type,

This function is very similar to create_character(), but the character created is temporary.

Temporary characters will be destroyed automatically when the scenario is reset, and are not saved in .dss files. They are commonly used for projectiles, effects, and other objects that can come and go multiple times.

Temporary characters can be destroyed before scenario reset by calling destroy_character(), and can be sent to the character recycle bin by calling send_character_to_recycle_bin().

Parameters

name	name of the new character
character_type	character's type
appearance	base appearance of character; pass NULL to use default appearance

Returns:

pointer of type diguyCharacter; NULL if creation failed

int diguyScenario::destroy_character

(

diguyCharacter *

character

)

This function destroys a character.

If a character of the same character type and appearance may be needed later in the scenario, consider using send_character_to_recycle_bin() instead. Characters can be retrieved from the recycle bin more quickly than creating them "from scratch" with create_character().

Parameters

character

pointer to a diguyCharacter

Returns:

0 on success, -1 on failure

DI-Guy Networking Notes:

This function should not be called on characters that are reflected network characters. Such characters are destroyed automatically by DI-Guy Networking.

int diguyScenario::destroy_character_later

(

diguyCharacter *

)

int diguyScenario::send_character_to_recycle_bin

(

diguyCharacter *

character

)

This function is an alternative way of removing a character from the scenario.

When a character is recycled it is removed from the scenario's list of active characters, but the memory associated with it is not freed. Instead, the character is placed in a "character recycle bin" from which it may be later retrieved with a call to retrieve_character_from_recycle_bin().

For an application that is creating and destroying a lot of characters with the same character types and appearances, this can avoid performance hiccups that happen when memory is allocated for new characters.

If it is known ahead of time what types and appearances of characters will be needed in the future, the recycle bin can be "pre-stocked" at scenario load time by first creating and then recycling a large number of characters all at once.

Returns:

0 on success, -1 on failure

diguyCharacter* diguyScenario::retrieve_character_from_recycle_bin	(	const char *	name,
		const char *	character_type,
		const char *	appearance,
		int	make_character_temporary = 0
	)

This function is an alternative way of creating a character.

The character recycle bin is checked for a recycled character whose character type and appearance match that requested by this call. Characters are sent to the recycle bin by a call to send_character_to_recycle_bin().

If a match is found the recycled character will be removed from the recycle bin, given the passed name, and placed in the scenario's list of characters, for the most part just as if the character had been created by a call to create_character(). Some things such as position, current action, etc., may need to be immediately set.

If a match is not found, this function returns NULL and a call to create_character() must be made instead.

Parameters

name	new name for the character retrieved from bin
character_type	the character type to retrieve from the bin
appearance	the appearance to retrieve from the bin, pass NULL or "default" to retrieve the default appearance
make_character_temporary	pass 1 to make character temporary, 0 to leave permanent

Returns:

0 on success, -1 on failure

The returned pointer must be destroyed using destroy_waypoint(). The scenario keeps no record of waypoints created with this function.

The weights of the waypoint control how long the "control handles" of the waypoint are, in meters. The longer the control handle, the more the path will be stretched in the direction of the waypoint's orientation.

Unless otherwise specified, callable from:

• C++
• Script

Parameters

tx,ty,tz	position in meters from the origin
rz,rx,ry	orientations in degrees counter-clockwise from the positive X axis
weight_in	how much influence this waypoint exerts over the path curve entering this waypoint
weight_out	how much influence this waypoint exerts over the path curve leaving this waypoint

By default, weight_in will be set to 1, and weight_out will be coupled to weight_in so that changes to one will affect the other. See diguyWaypoint::set_weight_in(). If a non-default value is passed for weight_out the weights of the waypoint will not be coupled.

Returns:

pointer to type diguyWaypoint

int diguyScenario::destroy_waypoint

(

diguyWaypoint *

waypoint

)

This function destroys a waypoint created by create_waypoint().

Path shapes created using this waypoint will not be affected; they make internal copies of the waypoints that are used to create them.

Do not call this function on waypoints not created by create_waypoint()! e.g., a waypoint returned by a call to diguyCharacterPath::get_waypoint_at_index().

Parameters

waypoint

waypoint to destroy

Returns:

0 on success, -1 on failure

• a scenario callback function registered by diguyApp::register_scenario_event_handler() or diguyApp::register_scenario_event_handler_from_library()
• a script registered by diguyApp::register_scenario_event_handler_script()
• a Script, Decision, or Library Function in the scenario whose "Event Type" is "Scenario"

Parameters

handler_name

name of the event handler to invoke

Returns:

DIGUY_CALLBACK_CONTINUE or DIGUY_CALLBACK_STOP

	)

This function registers a character event handler function that can later be mapped via a call to diguyCharacter::map_event_handler_to_callback_id().

Call unregister_character_event_handler() to unregister the function.

Parameters

handler_name	name of the event handler
callback	pointer to handler function

int diguyScenario::register_character_event_handler_from_library	(	const char *	handler_name,
		const char *	library_name,
		const char *	function_name,
		void *	callback_user_data = 0
	)

This function registers a character event handler function that can later be mapped via a call to diguyCharacter::map_event_handler_to_callback_id().

Unlike register_character_event_handler(), which directly passes a function pointer, this function looks up the function pointer from a shared library (a .dll under Windows, a .so under Unix).

The passed library_name should not include the .dll or .so extension; these will be added automatically. This allows for cross-platform scenarios that don't have differing dynamic library extensions built into them.

Call unregister_character_event_handler() to unregister the function.

Parameters

handler_name	name of the event handler
library_name	pointer to handler function
function_name	pointer to handler function
callback_user_data	pointer for user's own use; DI-Guy will do nothing to the contents of this pointer beyond passing it back when the handler function is called

Returns:

0 on success, -1 on failure

handler_script	Script text
handler_script_type	type of script; pass NULL for scenario to use the default script interpreter

Returns:

0 on success, -1 on failure

• sounds played by characters due to play_sound() and fire_weapon_n_times() calls

Note that Paths, Waypoints, and Event Beads per se are not saved, but rather their effects on the characters' positions and poses.

Parameters

filename

file in which to save review data

Returns:

0 on success, -1 on failure C++ Example:

// when shutting down the current run:
scenario->save_review_data("review0.dsr");

Parameters

num_sound_instances

override system default of 100

Returns:

none

void diguyScenario::set_automatic_graphics_lod_switching

(

int

enable_graphics_lod_switching

)

This function sets whether automatic graphics LOD switching should be enabled for certain graphics environments (see below).

By default it is enabled.

There are two ways that DI-Guy calculates the proper graphics LOD. For some graphics environments the calculation is done "manually", using data from a diguyViewCamera. In other environments the calculation is done by the graphics environment itself. The method used in each graphics environment is noted below.

OpenGL Version:

This function enables or disables automatic LOD switching. In this graphics environment LOD calculations are done by the renderer; information from the diguyViewCamera is not used.

DI-Guy Graphics API Version:

This function enables or disables automatic LOD switching. In this graphics environment LOD calculations are done by the renderer; information from the diguyViewCamera is not used.

(

int

enable_patching

)

For scene graph renderers, it can be necessary to patch the texture buffer object after the scene graph finishes updating various post processes (ground clamping for instance), or modifying the TBO with a local space camera.

This function lets DI-Guy knows to keep track of TBO shape index data, and not fill out the positions in the TBO data.

This function allows the end user to set the matrix in the TBO for each shape the character has. It requires diguyCharacter::set_final_tbo_position_matrix() is called after build_instance_groups() and before update_instancing_data()

void diguyScenario::set_default_lod_ranges	(	const char *	character_type,
		float *	ranges
	)

Sets the distances at which level of detail switching occurs for characters of the specified type.

Existing characters are not affected; only newly created characters will have the specified LOD switching ranges.

Characters will display with the highest level of detail when viewed from a distance between ranges[0] and ranges[1]. Characters will not display at all when viewed from further away than the highest switching range.

**

Note

ranges[0] should almost always be 0.0.

Parameters

character_type	character type name, as returned by get_character_type_at_index()
ranges	an array of 8 non-negative floating point numbers, each larger than the one before, specifying the LOD switching ranges in meters

Pass "all" for character_type to set the default ranges of all character types.

void diguyScenario::set_scale_graphics_lod_ranges_from_view_settings

(

int

do_scale

)

This function sets whether view and camera settings such as field-of-view (FOV) and window size should be taken into account when determining the graphics LOD from a character's LOD ranges.

The camera settings that are used are taken from the current render camera, as set by set_render_camera(). This happens automatically in DI-Guy Scenario, but must be set manually in the DI-Guy SDK.

DI-Guy graphics LODs are distance-based, but this approach can be problematic if the current camera's FOV is very narrow; a narrow FOV essentially acts like a telephoto lens. In this case a character that is far away, and would therefore be rendered with few polygons, can actually be quite large in the 3D view.

Setting this flag to 1 will cause the FOV to be taken into account when calculating the effective distance of a character from the camera.

Many DI-Guy LOD distances assume that the vertical FOV of the view is around 40. Smaller FOVs will scale the distances larger so that LOD changes happen further out. Likewise larger FOVs will scale the distances smaller; in this case even nearby characters will appear small and therefore need less resolution.

do_scale - pass 1 to enable scaling, 0 to disable

int diguyScenario::get_scale_graphics_lod_ranges_from_view_settings

(

)

Returns: most recent setting of set_scale_graphics_lod_ranges_from_view_settings()

void diguyScenario::set_automatic_motion_lod_switching

(

int

enable_motion_lod_switching

)

This function sets whether automatic motion LOD switching should be enabled.

By default it is enabled in DI-Guy Scenario, and disabled in a DI-Guy API application.

When running in a user application that uses the DI-Guy API, the primary view's camera's position and orientation must be kept consistent with the application's perception of current camera settings. A pointer to the primary view's camera can be obtained by calling get_scenario_camera().

The following describes the algorithm used by automatic motion LOD switching:

• if a character is in front of the primary view's camera, the motion LOD is set to 1 (animate all joints)

• else set motion LOD to 5 (stop animating everything but base position)

  Note that if there are multiple views open on the scenario, the character must be behind all cameras for the motion LOD to be set to 5.

  Also, if the history type of the character (as set by diguyCharacter::set_history_type()) is anything but DIGUY_HISTORY_TYPE_NONE, motion LOD 1 will be used since during scenario playback the character might be in front of any camera.

int diguyScenario::get_automatic_motion_lod_switching

(

)

This function returns whether automatic motion LOD switching is be enabled for characters in the scenario, as set by set_automatic_motion_lod_switching().

Returns:

1 if LODs enabled; 0 if not

Overriding the detonation radius will NOT work on broadcast detonations since the override value is not transmitted.

diguyImpact* diguyScenario::find_character_at_screen_coords	(	diguyView *	view,
		float	sx,
		float	sy
	)

This function checks for intersection against characters in the specified view.

To check for intersections against both characters and scene objects, call get_intersection_at_screen_coords().

The returned diguyImpact pointer is owned by the scenario and should not be deleted. It will remain valid until the next call to any one of the following functions:

• find_character_at_screen_coords()
• get_impact_at_screen_coords()
• get_intersection_at_screen_coords()

This function should only be called from a DI-Guy Scenario Plugin.

Parameters

view	view to check
sx,sy	view coordinates to check

Returns:

pointer of type diguyImpact; NULL if no character intersected

Callable From:

• DI-Guy Scenario Plugin

diguyImpact* diguyScenario::get_impact_at_screen_coords	(	diguyView *	view,
		float	sx,
		float	sy,
		int	use_octtree = 0
	)

This function creates an impact object based on the sx and sy in the specified view.

This function will trigger an impact callback on individuals who are touched, (it will not however kill characters who don't have impact callbacks.

The returned diguyImpact pointer is owned by the scenario and should not be deleted. It will remain valid until the next call to any one of the following functions:

• find_character_at_screen_coords()
• get_impact_at_screen_coords()
• get_intersection_at_screen_coords()

This function should only be called from a DI-Guy Scenario Plugin.

Parameters

view	view to check
sx,sy	view coordinates to check
use_octtree	use the octtree; will not test against all characters unless they are explicitly added, but much faster

Returns:

pointer of type diguyImpact;

Callable From:

• DI-Guy Scenario Plugin

diguyImpact* diguyScenario::get_intersection_at_screen_coords	(	diguyView *	view,
		float	sx,
		float	sy,
		int	use_octtree = 0
	)

This function checks for intersection against the world and characters in the specified view.

Unlike the function get_impact_at_screen_coords(), this function doesn't trigger callbacks; instead, it just fills out the impact info.

The returned diguyImpact pointer is owned by the scenario and should not be deleted. It will remain valid until the next call to any one of the following functions:

• find_character_at_screen_coords()
• get_impact_at_screen_coords()
• get_intersection_at_screen_coords()

This function should only be called from a DI-Guy Scenario Plugin.

Parameters

view	view to check
sx,sy	view coordinates to check
use_octtree	use the octtree; will not test against all characters unless they are explicitly added, but much faster

Returns:

diguyImpact with the xyz location of the intersection; NULL if there was nothing to intersect there

Callable From:

• DI-Guy Scenario Plugin

int diguyScenario::intersect_static_geometry	(	float	origin_x,
		float	origin_y,
		float	origin_z,
		float	dir_x,
		float	dir_y,
		float	dir_z,
		float	max_distance_to_test,
		float *	intersection_x,
		float *	intersection_y,
		float *	intersection_z,
		float *	normal_x = NULL,
		float *	normal_y = NULL,
		float *	normal_z = NULL,
		int	use_callback = 1
	)

This function checks for intersection against the world and returns basic collision results.

This function will only return valid results in environments where the DI-Guy geometry octtree is available; currently that is when using OpenGL and the DI-Guy flight geometry loader. DI-Guy Scenario is such a case.

Parameters

origin_x,origin_y,origin_z	starting location of the ray trace
dir_x,dir_y,dir_z	direction of ray trace (should be normalized)
max_distance_to_test	max distance ray will travel;
1.0	will test an infinitely long ray
intersection_x,_y,and	_z world location of intersection
normal_x,normal_y,normal_z	normal of intersection surface

Smaller values for max_distance_to_test will result in better performance.

The location of the intersection point is returned in the intersection x, y, and z pointers.

The normal of the surface intersected is returned in the normal x, y, and z pointers.

Returns:

1 if intersection occurred, 0 if not.

float diguyScenario::ground_clamp	(	float	x,
		float	y,
		float	z,
		int *	valid = NULL,
		int	use_altitude_function = 1,
		int	use_octtree = 0
	)

This function returns the z height, or altitude, of the uppermost piece of terrain under the passed x, y, z point.

Two methods can be used to determine the altitude: a custom scenario altitude function set by the user, or by testing against DI-Guy's internal octtree calculated from terrain geometry.

See set_altitude_function() for information on the scenario altitude function. DI-Guy Scenario has its own version of this function, which defaults to using the octtree when it's available, and falls back on using a screen render and Z-buffer check when it's not.

Note that the octtree is not always available. In general, it is available only in DI-Guy Scenario, or when the built-in OpenGL renderer and DI-Guy flight geometry loader are in use. Users of the SDK typically have their own representations of terrain and structures.

Parameters

x,y,z	world location to ground clamp
valid	optional pointer to get an explicit result if anything was hit
use_altitude_function	pass 1 to use scenario altitude function (tried first)
use_octtree	pass 1 to use internal octtree

Returns:

new_z if ground clamp was possible, original z if not

int diguyScenario::set_fire_weapon_intersection_function

(

diguyScenarioFindImpactOnLineFunction *

impact_function

)

The following prototype should be used for the impact function:

int impact_func(diguyImpact* impact,
    float from_x,
    float from_y,
    float from_z,
    float to_x,
    float to_y,
    float to_z,
    diguyScenario* s);

When a character fires their weapon, DI-Guy calls this function with a pointer to the diguyImpact that must be filled out, the x, y, z position of the shot, and the target x, y, z.

The impact function should then do an intersection test and return 1 if a hit occurred.

By default the impact should have both the attacker and the munition type already specified. The intersection function must at least call diguyImpact::set_valid_impact() for the system to consider the impact valid. See diguyImpact for a sample function.

Callable From:

• C++

static void diguyScenario::set_default_fire_weapon_intersection_function ( diguyScenarioFindImpactOnLineFunction *  impact_function )

static

This function sets an impact function that will be added to all new scenarios.

It can be overridden by an explicit call to diguyScenario::set_fire_weapon_intersection_function(). See that function for details.

Callable From:

• C++

diguyImpact* diguyScenario::map_color_to_impact	(	char	r,
		char	g,
		char	b
	)

Most DI-Guy visual objects (e.g., characters, path shapes, waypoints) have a unique identified, or UID.

In many cases these UID values can be coded into 24-bit color values. This can be useful for implementing some types of intersection detection functions, in which each visual object is rendered with a different color.

This function will take the passed color values and update internal DI-Guy state of which objects objects have been hit.

It will also return an impact record containing information a subset of that information.

This can include:

• the hit character, if one was hit
• the hit link and shape of the character
• the hit scene object, if one was hit

Note that the returned impact pointer is owned by DI-Guy and is temporary. The information you need from it should be immediately read, and the pointer should not be stored.

diguyImpact* diguyScenario::get_last_env_impact_info

(

)

When the callback with id diguyScenario::CALLBACK_ID_SCENE_OBJECT_IMPACT is called, this function will return the impact object containing information about that impact.

There may be multiple impacts that result from some operations. In this case this function should be called multiple times, until it returns NULL. When processing of data from each successive impact is done, call set_last_impact_been_processed() to queue up the next impact object for processing.

The maximum number of unprocessed impacts is finite, and set by the function set_max_unprocessed_impacts().

Note that the returned impact pointers are owned by DI-Guy and are temporary. The information you need from them should be immediately read, and the pointers should not be stored.

void diguyScenario::set_last_impact_been_processed

(

)

Reading of data from the last impact information will be considered complete when this function is called.

void diguyScenario::set_last_env_impact_info

(

const diguyImpact &

impact

)

This function will add the passed impact object to the list of impact objects to be processed by calls to get_last_env_impact_info().

An internal copy of the impact object is made.

void diguyScenario::set_max_unprocessed_impacts

(

int

max_unprocessed_impacts

)

Sets the maximum number of unprocessed impacts there can be.

The unprocessed impact array is a first-in-first-out queue. If an impact occurs that pushes the number of unprocessed impacts past this maximum number, earlier impacts will be dropped from the array.

The initial value is 10.

int diguyScenario::set_default_point_los_function

int diguyScenario::find_navigation_path	(	float	x1,
		float	y1,
		float	z1,
		float	x2,
		float	y2,
		float	z2,
		const char *	via_region,
		diguyPathShape *	path_shape,
		float	cost_bias_for_preferred_regions = 0.25f,
		int	preferred_subregions_mask = DIGUY_SUBREGION_MASK_NONE,
		float	cost_bias_for_neutral_regions = 1.1f,
		int	repulsed_regions_mask = DIGUY_SUBREGION_MASK_NONE,
		float	cost_bias_for_repulsive_regions = 100.0f
	)

The scenario will attempt to create a navigation path on the via_region.

An A* path planning algorithm is used to find the path. See also diguyCharacter::agent_move_to_point() and diguyCharacter::agent_move_to_point_via_subregions().

Parameters

x1,y1,z1	start location
x2,y2,z2	end location
via_region	name of the region to run A* on
path_shape	path shape that stores the created path
preferred_subregions_mask	diguySubregionMask value of regions preferred for travel
cost_bias_for_preferred_regions	how much cheaper it will be to cross spaces that are part of desired subregion; should be < 1.0
cost_bias_for_neutral_regions	how much more expensive it will be to cross spaces that are not part of desired subregion; see below for more information
repulsed_regions_mask	diguySubregionMask value of regions not preferred for travel
cost_bias_for_repulsed_regions	how much more expensive it will be to cross regions that are marked as repulsive; pass DIGUY_DEFAULT_FLOAT to avoid completely

Pass DIGUY_DEFAULT_FLOAT for cost_bias_for_neutral_regions and cost_bias_for_repulsed_regions to specify that they should be avoided completely.

The preferred_subregions_mask and repulsed_regions_mask use DI-Guy subregion mask values combined together. For example, DIGUY_SUBREGION_MASK_SIDEWALK | DIGUY_SUBREGION_MASK_CROSSWALK.

For cost_bias_for_neutral_regions, specifying a non-zero value for this lowers the likelihood that searches fail on disjointed subregions. A value < 1 will cause the planner to run faster but explore fewer points, possibly missing preferred regions. Values greater then 1 will explore more points but will be slower.

Returns:

0 on success, -1 on failure

void diguyScenario::set_max_distance_planning_multiplier

(

float

mul

)

Sets an upper limit on how far a character is willing to travel as a multiple of the straight line distance between point A and point B before declaring that it can't get to a location.

Note that internally the straight line distance is forced to have a lower bound of 10 meters, so a character is always willing to travel a minimum of 10 * max_distance_planning_multiplier meters.

Defaults to -1, which means off.

float diguyScenario::get_max_distance_planning_multiplier

(

)

Returns: float constant that's used to decide if planner should give up; -1 means off.

float diguyScenario::get_time_spent_path_planning_this_frame

(

)

This function returns in seconds how much time has been spent path planning during the current frame.

It can be used to avoid 100 characters simultaneously hitting the path planner.

For more information on how the Lua C api works see: http://www.lua.org/pil/24.html

NOTE:

Currently all scenarios share the same underlying Lua state object. This may cause issues in applications with multiple scenarios.

int diguyScenario::push_qt_pointer_to_lua	(	void *	lua_state,
		const char *	class_name,
		void *	ptr
	)

Mainly used to pass a qt pointer to lua so lqt can be used to modify/read from the widget.

This requires the that the lqt package is loaded; see the lqt.lua utility package for more info.

Parameters

lua_state	a Lua_State pointer, might be the same as get_lua_state(); depends if the calling function is inside a coroutine
class_name	class name should be a core class of qt with a star after it; i.e. "QWidget*" or "QLineEdit*"
ptr	pointer to that is returned to the calling function in lua

Callable From:

• C++

C++ Example:

int push_graphics_view_to_lua(lua_State *L)
{
        bdiQGraphicsView* graphics_view = get_primary_3d_window_graphics_view();
        if (m_scenario->push_qt_pointer_to_lua(L, "QGraphicsView*", graphics_view) == -1)
        {
                return 0;
        }
        return 1;
}

Plug-in init code:

lua_State* L = (lua_State*)scenario->get_lua_state();
if (L)
{
        lua_register(L, "get_graphics_view", push_graphics_view_to_lua);
}

In lua:

local graphics_view = get_graphics_view();

		const char *	arg3_type,
		void *	argument3,
		const char *	arg4_type,
		void *	argument4,
		int	has_return_string = 0
	)

The most open function calling function available, if this doesn't manage to accomplish what you need you probably want to start using the lua interpreter directly.

The type arguments are string versions of the type being sent to lua, options include:

• '' - empty argument
• 'b' boolean - void* argument1 is assumed to be an int
• 'f' field - void* argument1 assumed to be character string of a field of a global lua object; supports nested fields like foo.bar.a
• 's' string - void* argument1 assumed to be character string
• 'd' double - void* argument is assumed to be a double
• diguy... - void* argument assumed to be a diguy class pointer ie "diguyCharacter", "diguyCrowd" (no star used for diguy classes)
• Q...* - void* argument is assumed to be a pointer to a child of QObject; the class name should be a core class of qt with a star after it, e.g. "QWidget*" or "QLineEdit*"

Parameters

lua_object	a global lua object
function_name	name of the function to call
arg(1/2/3/4)_type	is the data type
argument(1/2/3/4)	void* pointers to data
has_return_string	if set to 1 function will pop the top value of the lua stack and return it as a string

Returns:

NULL or string representation of lua_object:function_name(argument)

The returned string should be copied if it needs to be used later.

Callable From:
