Detailed Description

The class that represents a DI-Guy Crowd.

Member Enumeration Documentation

anonymous enum

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

CALLBACK_ID_CREATE

 This callback will be called when a new crowd is created.

 Note that this callback can only be added by calling
 diguyScenario::add_default_crowd_callback(); adding it
 with diguyCrowd::add_callback() will have no effect, as
 by that time the crowd has already been created.
 There is no associated callback character.

CALLBACK_ID_DESTROY

 This callback will be called when a crowd is destroyed. There
 is no associated callback character.

CALLBACK_ID_CROWD_MEMBER_KILLED

 This callback will be called when a member of the crowd is
 killed.

- The callback character is the crowd member that was killed.
- The callback impact contains the impact information.

CALLBACK_ID_CROWD_MEMBER_IMPACT

 Similar to diguyCharacter::CALLBACK_ID_IMPACT, this callback will
 be called when a member of the crowd is hit by a detonation.  If
 this callback isn't present the impacted character automatically
 will die.  Handling this callback allows for the implementation
 of custom damage models at a crowd level.

- The callback character is the crowd member that was hit.
- The callback impact contains the impact information.

CALLBACK_ID_NEARBY_SCENE_OBJECT_IMPACT

 This callback will be called when a detonation occurs within the
 awareness radius (as set by set_awareness_radius()) of the
 crowd's current bounds.

- The callback character is the character that caused the
    detonation.
- The callback impact contains the impact information.

CALLBACK_ID_NEARBY_WEAPON_FIRED

 This callback will be called when a weapon is fired within the
 awareness radius (as set by set_awareness_radius()) of the
 crowd's current bounds.

- The callback character is the character that fired the weapon.

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.

Member Function Documentation

const char* diguyCrowd::get_name ( )

Returns: name of this object; this value will never be NULL.

int diguyCrowd::set_name ( const char * name )

This function sets the name of this object.

Returns:

const char* diguyCrowd::get_ui_name ( )

Returns: UI name of this object; this value will never be NULL.

int diguyCrowd::set_ui_name ( const char * ui_name )

This function sets the UI name of this object.

The UI name is what shows up in user interface windows that show information about this crowd.

For example, the crowd name may be "crowd_squad1", the UI name may be "Squad 1".

By default the UI name matches the internal name.

Returns:

0 on success, -1 on failure

This pointer will never be NULL.

Returns:

type name of the object

This function enables or disables the crowd.

Disabling a crowd does not disable or hide the members of the crowd. It does turn off any effects the crowd may have on agent actions, position, orientation, etc. To enable or disable all agents in the crowd, use set_all_members_enabled() instead.

Disabled crowds also will not interact with companion crowds.

Returns:

0 on success, -1 on failure

Available as Decision Bead/Event

int diguyCrowd::set_current_behavior ( const char * behavior_name )

This is a shortcut for calling diguyCharacter::set_current_behavior() for all members of the crowd.

It's recommended that one of the higher level functions above that set behavior, for example agent_wander_region(), is used. These functions allow for setting the most common parameters that affect the behavior in one function call.

int diguyCrowd::set_current_params_from_profile	(	const char *	profile_name,
		int	retain_focus_objects = `1`,
		int	retain_navigation_values = `1`
	)

This is a shortcut for calling diguyCharacter::agent_set_current_params_from_profile() for all members of the crowd.

This will affect most of the parameters of agents in this crowd, including behavior, posture and variant, etc. Focus character and group by default are changed, but can be left alone by passing 0 for retain_focus_objects.

Parameters

profile_name	name of crowd profile whose default parameters should be used
retain_focus_objects	pass 1 to change focus objects to those of the named profile, 0 to retain existing settings
retain_navigation_values	keeps path_shape, region, subregion, path planner cost values and rules the same

Returns:

0 on success, -1 on failure

void diguyCrowd::set_current_behavior_region_border_is_solid ( int is_solid )

This is a shortcut for calling diguyCharacter::agent_set_current_behavior_region_border_is_solid() for all members of the crowd.

Sets whether the walls of the region the agent is in are solid. If they are, the agent will treat the walls as if they are solid walls in the environment. If not, the agent is free to walk through them.

Pass 1 to make border walls solid, 0 to make them freely passable.

Available as Decision Bead/Event

void diguyCrowd::set_current_postures ( diguyMotionPosture posture )

Sets the posture of all members of the crowd and restarts their behaviors.

void diguyCrowd::set_current_variants ( diguyMotionVariant variant )

Sets the variant of all members of the crowd and restarts their behaviors.

int diguyCrowd::set_initial_params_from_profile ( const char * profile_name )

This function is similar to set_current_params_from_profile(), but instead sets initial params.

Parameters

profile_name name of crowd profile whose default parameters should be used

0 on success, -1 on failure

int diguyCrowd::is_current_behavior	(	const char *	behavior_name,
		float	threshold = `0.5f`
	)

If more than threshold ratio are doing behavior_name then the function will return 1. The default 0.5 yields a simple majority check.

Returns:

1 if true, 0 if false

Available as Decision Bead/Event

int diguyCrowd::is_current_behavior_and_focus_character	(	const char *	behavior_name,
		const char *	focus_character_name,
		float	threshold = `0.5f`
	)

Similar to is_current_behavior(), but checks both behavior and focus character.

int diguyCrowd::is_current_behavior_and_focus_group	(	const char *	behavior_name,
		const char *	group_name,
		float	threshold = `0.5f`
	)

Similar to is_current_behavior(), but checks both behavior and focus group.

int diguyCrowd::is_crowd_dead ( float threshold = 0.5f )

Similar to is_current_behavior(), but checks whether characters are dead.

int diguyCrowd::add_companion_crowd ( diguyCrowd * companion_crowd )

This function makes the specified crowd a "companion crowd" of this crowd.

Parameters

companion_crowd name of crowd to become a companion

Returns:

0 on success, -1 on failure

int diguyCrowd::remove_companion_crowd ( diguyCrowd * companion_crowd )

This function removes the specified crowd as a companion crowd.

Parameters

companion_crowd name of former companion

Returns:

0 on success, -1 on failure

void diguyCrowd::set_dynamic_object_avoidance_method ( diguyDynamicAvoidanceMethod method )

Usually these are scene objects and fixed props.

The enumeration is defined in diguy_constants.h.

Parameters

method avoidance method to use

Returns:

0 on success, -1 on failure

diguyStaticAvoidanceMethod diguyCrowd::get_static_object_avoidance_method ( )

Returns: current static object avoidance method; see set_static_object_avoidance_method()

callback_id	integer id of when this callback is to be called
callback_params	not currently used; pass NULL
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 callback is invoked

0 on success, -1 on failure

Callable From:

C++

int diguyCrowd::remove_callback	(	int	callback_id,
		diguyCrowdCallback *	callback
	)
