◆ Collide()

bool VehicleCollisionTesterCastCylinder::Collide	(	PhysicsSystem &	inPhysicsSystem,
		const VehicleConstraint &	inVehicleConstraint,
		uint	inWheelIndex,
		RVec3Arg	inOrigin,
		Vec3Arg	inDirection,

	)		const

overridevirtual

Do a collision test with the world

Parameters

inPhysicsSystem	The physics system that should be tested against
inVehicleConstraint	The vehicle constraint
inWheelIndex	Index of the wheel that we're testing collision for
inOrigin	Origin for the test, corresponds to the world space position for the suspension attachment point
inDirection	Direction for the test (unit vector, world space)
inVehicleBodyID	This body should be filtered out during collision detection to avoid self collisions
outBody	Body that the wheel collided with
outSubShapeID	Sub shape ID that the wheel collided with
outContactPosition	Contact point between wheel and floor, in world space
outContactNormal	Contact normal between wheel and floor, pointing away from the floor
outSuspensionLength	New length of the suspension [0, inSuspensionMaxLength]

Returns: True when collision found, false if not

Implements VehicleCollisionTester.

◆ PredictContactProperties()

void VehicleCollisionTesterCastCylinder::PredictContactProperties	(	PhysicsSystem &	inPhysicsSystem,
		const VehicleConstraint &	inVehicleConstraint,
		uint	inWheelIndex,
		RVec3Arg	inOrigin,
		Vec3Arg	inDirection,
		const BodyID &	inVehicleBodyID,

		SubShapeID &	ioSubShapeID,
		RVec3 &	ioContactPosition,
		Vec3 &	ioContactNormal,
		float &	ioSuspensionLength
	)		const

overridevirtual

Do a cheap contact properties prediction based on the contact properties from the last collision test (provided as input parameters)

Parameters

inPhysicsSystem	The physics system that should be tested against
inVehicleConstraint	The vehicle constraint
inWheelIndex	Index of the wheel that we're testing collision for
inOrigin	Origin for the test, corresponds to the world space position for the suspension attachment point
inDirection	Direction for the test (unit vector, world space)
inVehicleBodyID	The body ID for the vehicle itself
ioBody	Body that the wheel previously collided with
ioSubShapeID	Sub shape ID that the wheel collided with during the last check
ioContactPosition	Contact point between wheel and floor during the last check, in world space
ioContactNormal	Contact normal between wheel and floor during the last check, pointing away from the floor
ioSuspensionLength	New length of the suspension [0, inSuspensionMaxLength]
