Detailed Description

DtMissileMoveToControllerComponent is a controller that maneuvers a missile toward a given target point.

End User Description: It registers for DtTargetPointType messages, through which it receives its target location. It generates thrust and steering outputs.

Uses Descriptor Type: DtComponentDescriptor

Member Function Documentation

virtual void DtMissileMoveToControllerComponent::tick

(

)

[virtual]

Calculate new control values.

Reimplemented from DtSimComponent.

virtual DtString DtMissileMoveToControllerComponent::type

(

)

const [virtual]

Returns a string identifies the class type of component.

Type values are defined in compTypes.h. DtSimComponent creation functions are registered with the DtSimComponentFactory using the type values as the key.

Returns:

DtMissileMoveToType

Reimplemented from DtMissileControllerComponent.

Reimplemented in DtMissileTrackEntityController, and DtLasingMissileTrackController.

virtual void DtMissileMoveToControllerComponent::setTargetPoint

(

const DtVector &

targetPoint

)

[virtual]

Sets the target point location.

It also calculates and sets myDistanceToTarget.

virtual const DtVector& DtMissileMoveToControllerComponent::targetPoint

(

)

const [virtual]

virtual void DtMissileMoveToControllerComponent::setTargetVelocity

(

const DtVector &

arg

)

[virtual]

Set the current target velocity for the missile.

virtual const DtVector& DtMissileMoveToControllerComponent::targetVelocity

(

)

const [virtual]

virtual void DtMissileMoveToControllerComponent::calculateSteering	(	const DtVector &	relativeVelocity,
		const DtVector &	localPosition,
		const DtVector &	targetVelocity,
		const DtVector &	targetPoint,
		double &	maneuverAccelXOut,
		double &	maneuverAccelYOut,
		double &	maneuverAccelZOut
	)		[virtual]

Just calls down to calculateSteeringToPoint (ignoring targetVelocity).

Implements DtMissileControllerComponent.

Reimplemented in DtMissileTrackEntityController.

static void DtMissileMoveToControllerComponent::targetPointCallback	(	DtSimMessage *	msg,
		void *	usr
	)		[static]

Instances of this component will register this callback with their own 'this' pointer as user data with the msg executive requesting notification of move-to tasks.

virtual void DtMissileMoveToControllerComponent::processTargetPointTask

(

DtSimMessage *

msg

)

[virtual]

This function calls setTargetPoint(), passing in the location of target point given in the target-point message.

static DtSimComponent* DtMissileMoveToControllerComponent::creator	(	const DtString &	name,
		DtVrfObject *	owner,
		DtSimManager *	simManager,
		DtComponentDescriptor *	desc = 0,
		DtReaderWriterRegistry *	parentRegistry = 0
	)		[static]

(const DtString&,DtVrfObject*,DtSimManager*,

Parameters:

name	Reader writer name of this component.
owner	The DtVrfObject that owns this component
simManager	The simulation manager (provides access to terrain, message interface, simulation clock).
desc	The component descriptor used to initialize this component.
parentRegistry	Pointer to the parent reader writer registry (the containing object that reads/writes this object).

(const DtString&,DtVrfObject*,DtSimManager*, DtComponentDescriptor*,DtReaderWriterRegistry* parentRegistry)

Returns:

New instance of this class.

Reimplemented in DtLasingMissileTrackController, and DtMissileTrackEntityController.

const DtMissileMoveToControllerComponent& DtMissileMoveToControllerComponent::operator=

(

const DtMissileMoveToControllerComponent &

orig

)

[protected]

assignment operator; see comments on copy constructor!

virtual void DtMissileMoveToControllerComponent::registerTaskMsgCallbacks

(

)

[protected, virtual]

Overrides this so it can register its interest in MoveTo commands.

Reimplemented from DtTaskControllerComponent.

Reimplemented in DtMissileTrackEntityController.

virtual bool DtMissileMoveToControllerComponent::setupControlPoint

(

)

[protected, virtual]

Returns the boolean member data flag myMissilesTargeted, indicating whether or not a target location has been set for the missile.

Reimplemented in DtMissileTrackEntityController, and DtLasingMissileTrackController.

virtual double DtMissileMoveToControllerComponent::findDesiredSpeed

(

)

[protected, virtual]

Returns the maximum speed for the missile.

Reimplemented in DtMissileTrackEntityController.

virtual void DtMissileMoveToControllerComponent::doMoving

(

)

[protected, virtual]

Calculates and sets the maneuver and thrust port values for this frame.

It takes the frame duration dT as an argument. To calculate maneuver acceleration, it calls calculateSteering(). For thrust, it first calls desiredSpeed() to get the appropriate speed for the missile, and then calls approximateThrust(), passing in the desired speed as a parameter.
