Detailed Description

DtLaserTargetDesignatorSimLogic provides the capability to turn a laser target designator device on/off. A laser may be either immediately toggled on/off or started and then stopped at some later time, to provide a 'press and hold' interface to the device.

Input handler details (for configuring in an SMS input configuration file):

Group: "laser-target-designator"
Handler functions: "toggle-laser", "press-and-hold-to-lase"

Constructor & Destructor Documentation

◆ DtLaserTargetDesignatorSimLogic()

makVre::DtLaserTargetDesignatorSimLogic::DtLaserTargetDesignatorSimLogic ( )

Constructor for DtLaserTargetDesignatorSimLogic.

Initializes component state with default values

◆ ~DtLaserTargetDesignatorSimLogic()

virtual makVre::DtLaserTargetDesignatorSimLogic::~DtLaserTargetDesignatorSimLogic ( )

overridevirtual

Virtual destructor for DtLaserTargetDesignatorSimLogic.

Member Function Documentation

◆ initialize()

virtual bool makVre::DtLaserTargetDesignatorSimLogic::initialize	(	DtPlayerStation *	player,
		DtInitTable &	config )

overridevirtual

Initializes the laser target designator component.

Parameters

player	Pointer to the player station this component belongs to
config	Configuration table containing laser designator settings

Returns: True if initialization succeeded, false otherwise

Configures input handlers, sets up message handlers, initializes sensor modes, and connects to necessary signals for pose information updates

Reimplemented from makVre::DtPlayerComponent.

References makVre::DtPlayerComponent::player().

◆ tick()

virtual void makVre::DtLaserTargetDesignatorSimLogic::tick ( double dt )

overridevirtual

Called every frame to update the laser designator.

Parameters

dt	Delta time since the last frame in seconds

Updates the laser target location if the laser is currently active

Implements makVre::DtPlayerComponent.

◆ shutdown()

virtual void makVre::DtLaserTargetDesignatorSimLogic::shutdown ( )

overridevirtual

Shuts down the laser target designator component.

Cleans up input handlers, message handlers, disconnects signals, and restores original sensor mode

Reimplemented from makVre::DtPlayerComponent.

◆ type()

virtual const char * makVre::DtLaserTargetDesignatorSimLogic::type ( ) const

overridevirtual

Returns the type identifier for this component.

Returns: The type string for DtLaserTargetDesignatorSimLogic

Implements makVre::DtPlayerComponent.

◆ startLasingLocation()

virtual void makVre::DtLaserTargetDesignatorSimLogic::startLasingLocation ( )

virtual

Starts the laser target designator at the current aim point.

Performs a ray cast from the observer through the center of the screen, sends a StartLasingLocationMessage with the detected location, and sets the laser state to on

◆ stopLasingLocation()

virtual void makVre::DtLaserTargetDesignatorSimLogic::stopLasingLocation ( )

virtual

Stops the laser target designator.

Sends a StopLasingLocationMessage and sets the laser state to off

◆ updateLasingLocation()

virtual void makVre::DtLaserTargetDesignatorSimLogic::updateLasingLocation ( )

virtual

Updates the current laser target location.

Performs a ray cast from the observer through the center of the screen and sends a SetLasingLocationMessage with the updated location

◆ toggleLasingState()

virtual void makVre::DtLaserTargetDesignatorSimLogic::toggleLasingState ( )

virtual

Toggles the laser target designator on or off.

If the laser is currently on, calls stopLasingLocation(); otherwise, calls startLasingLocation()

◆ toggleIRSensor()

virtual void makVre::DtLaserTargetDesignatorSimLogic::toggleIRSensor ( )

virtual

Toggles between IR and visual sensor modes.

Switches the observer's sensor mode between IR and visual, updating the IRSensorOn state attribute accordingly

◆ handleToggleLaser()

virtual void makVre::DtLaserTargetDesignatorSimLogic::handleToggleLaser ( float value )

virtual

Input handler function for toggle laser action.

Parameters

value Input value (1.0 to toggle the laser state)

Toggles the laser on/off when the incoming value is 1

◆ handlePressAndHoldToLase()

virtual void makVre::DtLaserTargetDesignatorSimLogic::handlePressAndHoldToLase ( float value )

virtual

Input handler function for press-and-hold lasing action.

Parameters

value Input value (1.0 = on, 0.0 = off)

Turns the laser on if the incoming value is 1, and turns it off if the incoming value is 0

◆ isLasingOn()

virtual bool makVre::DtLaserTargetDesignatorSimLogic::isLasingOn ( ) const

virtual

Checks if the laser is currently active.

Returns: True if the laser is currently on, false otherwise

Returns the current state of the "laserOn" attribute

◆ handleMenuMessage()

virtual DtVreMessageResult makVre::DtLaserTargetDesignatorSimLogic::handleMenuMessage ( makVre::DtVreMessage * msg )

virtual

Handles menu action messages for the laser designator.

Parameters

msg	The menu action message to handle

Returns: Message handling result indicating if the message was handled

Processes "toggleLasingState", "toggleIRSensor", and "laserCodeInput" actions

◆ handleLaserOnChange()

void makVre::DtLaserTargetDesignatorSimLogic::handleLaserOnChange ( bool on )

protected

Handles changes to the laserOn attribute.

Parameters

on	New value of the laserOn attribute

Updates the laserState attribute text based on the on/off state

◆ updatePoseInformation()

void makVre::DtLaserTargetDesignatorSimLogic::updatePoseInformation ( )

protected

Updates pose information for VR head tracking.

If VR is enabled and disableVrHeadPose is true, this method resets the camera position and orientation to prevent head tracking from affecting the aiming of the laser designator

Member Data Documentation

◆ myObserver

makVrv::DtObserver* makVre::DtLaserTargetDesignatorSimLogic::myObserver

protected

Pointer to the observer used for ray casting and sensor mode control.

◆ myInputConfigFile

std::string makVre::DtLaserTargetDesignatorSimLogic::myInputConfigFile

protected

Path to the input configuration file.

◆ myIRSensorMode

std::string makVre::DtLaserTargetDesignatorSimLogic::myIRSensorMode
