Member Function Documentation

virtual const char* DtFrictionlessGravityActuator::type ( ) const

overridevirtual

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. Warning: this function should always return the same pointer and it should be valid forever. This means the data should be static.

Returns: DtGravityActuatorType

Reimplemented from DtFallingFromSkyActuatorComponent.

Reimplemented in DtFrictionlessGravityCollisionsActuator.

static DtSimComponent* DtFrictionlessGravityActuator::creator	(	const DtString &	name,
		DtLocalObject *	owner,
		DtSimulationServices *	simManager,
		DtComponentDescriptor *	desc = `0`,
		DtReaderWriterRegistry *	parentRegistry = `0`
	)

static

Parameters

name	Reader writer name of this component.
owner	The DtLocalObject 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).

Returns: New instance of this class.

virtual void DtFrictionlessGravityActuator::preFirstTickInit ( )

overridevirtual

This function can be overridden to initialize a component before it is ticked for the first time. The implementation for this function is empty. It is called by timedTick if myFirstTick is true.

Reimplemented from DtSimComponent.

Reimplemented in DtFrictionlessGravityCollisionsActuator.

virtual void DtFrictionlessGravityActuator::fallFromSky ( )

overrideprotectedvirtual

Causes the entity to fall from the sky, ignoring drag.

Reimplemented from DtFallingFromSkyActuatorComponent.

Reimplemented in DtFrictionlessGravityCollisionsActuator.

virtual void DtFrictionlessGravityActuator::integrate	(	const DtVector &	oldLocalPosition,
		const DtVector &	oldRelativeVelocity,
		const DtVector &	newRelativeAcceleration,
		DtVector &	newLocalPosition,
		DtVector &	newRelativeVelocity
	)

overrideprotectedvirtual

Integrates velocity and position.

Reimplemented from DtFallingFromSkyActuatorComponent.

virtual DtVector DtFrictionlessGravityActuator::initialRotationRate ( )

protectedvirtual

Returns the starting rotation rate of the object.
