Member Function Documentation

◆ AddBodiesFinalize()

JPH_NAMESPACE_BEGIN void BroadPhaseBruteForce::AddBodiesFinalize	(	BodyID *	ioBodies,
		int	inNumber,
		AddState	inAddState
	)

overridevirtual

Finalize adding bodies to the broadphase, supply the return value of AddBodiesPrepare in inAddState. Please ensure that the ioBodies array passed to AddBodiesPrepare is unmodified and passed again to this function.

Implements BroadPhase.

◆ CastAABox()

void BroadPhaseBruteForce::CastAABox	(	const AABoxCast &	inBox,
		CastShapeBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,

	)		const

overridevirtual

void BroadPhaseBruteForce::CastAABoxNoLock	(	const AABoxCast &	inBox,
		CastShapeBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,
		const ObjectLayerFilter &	inObjectLayerFilter
	)		const

overridevirtual

Same as BroadPhaseQuery::CastAABox but can be implemented in a way to take no broad phase locks.

Implements BroadPhase.

◆ CastRay()

void BroadPhaseBruteForce::CastRay	(	const RayCast &	inRay,
		RayCastBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,
		const ObjectLayerFilter &	inObjectLayerFilter
	)		const

overridevirtual

Cast a ray and add any hits to ioCollector.

Implements BroadPhaseQuery.

◆ CollideAABox()

void BroadPhaseBruteForce::CollideAABox	(	const AABox &	inBox,
		CollideShapeBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,
		const ObjectLayerFilter &	inObjectLayerFilter
	)		const

overridevirtual

Get bodies intersecting with inBox and any hits to ioCollector.

Implements BroadPhaseQuery.

◆ CollideOrientedBox()

void BroadPhaseBruteForce::CollideOrientedBox	(	const OrientedBox &	inBox,
		CollideShapeBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,
		const ObjectLayerFilter &	inObjectLayerFilter
	)		const

overridevirtual

Get bodies intersecting with an oriented box and any hits to ioCollector.

Implements BroadPhaseQuery.

◆ CollidePoint()

void BroadPhaseBruteForce::CollidePoint	(	Vec3Arg	inPoint,
		CollideShapeBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,
		const ObjectLayerFilter &	inObjectLayerFilter
	)		const

overridevirtual

Get bodies intersecting with a point and any hits to ioCollector.

Implements BroadPhaseQuery.

◆ CollideSphere()

void BroadPhaseBruteForce::CollideSphere	(	Vec3Arg	inCenter,
		float	inRadius,
		CollideShapeBodyCollector &	ioCollector,
		const BroadPhaseLayerFilter &	inBroadPhaseLayerFilter,
		const ObjectLayerFilter &	inObjectLayerFilter
	)		const

overridevirtual

Get bodies intersecting with a sphere and any hits to ioCollector.

Implements BroadPhaseQuery.

◆ FindCollidingPairs()

void BroadPhaseBruteForce::FindCollidingPairs	(	BodyID *	ioActiveBodies,
		int	inNumActiveBodies,
		float	inSpeculativeContactDistance,
		const ObjectVsBroadPhaseLayerFilter &	inObjectVsBroadPhaseLayerFilter,
		const ObjectLayerPairFilter &	inObjectLayerPairFilter,
		BodyPairCollector &	ioPairCollector
	)		const

overridevirtual

Find all colliding pairs between dynamic bodies Note that this function is very specifically tailored for the PhysicsSystem::Update function, hence it is not part of the BroadPhaseQuery interface. One of the assumptions it can make is that no locking is needed during the query as it will only be called during a very particular part of the update.

Parameters

ioActiveBodies	is a list of bodies for which we need to find colliding pairs (this function can change the order of the ioActiveBodies array). This can be a subset of the set of active bodies in the system.
inNumActiveBodies	is the size of the ioActiveBodies array.
inSpeculativeContactDistance	Distance at which speculative contact points will be created.
inObjectVsBroadPhaseLayerFilter	is the filter that determines if an object can collide with a broadphase layer.
inObjectLayerPairFilter	is the filter that determines if two objects can collide.
ioPairCollector	receives callbacks for every body pair found.

Implements BroadPhase.

◆ GetBounds()

AABox BroadPhaseBruteForce::GetBounds ( ) const

overridevirtual

Get the bounding box of all objects in the broadphase.

Implements BroadPhase.

◆ NotifyBodiesAABBChanged()

void BroadPhaseBruteForce::NotifyBodiesAABBChanged	(	BodyID *	ioBodies,
		int	inNumber,
		bool	inTakeLock
	)

overridevirtual

Call whenever the aabb of a body changes (can change order of ioBodies array) inTakeLock should be false if we're between LockModifications/UnlockModificiations in which case care needs to be taken to not call this between UpdatePrepare/UpdateFinalize

Implements BroadPhase.

◆ NotifyBodiesLayerChanged()

void BroadPhaseBruteForce::NotifyBodiesLayerChanged	(	BodyID *	ioBodies,
		int	inNumber
	)

overridevirtual

Call whenever the layer (and optionally the aabb as well) of a body changes (can change order of ioBodies array)

Implements BroadPhase.

◆ RemoveBodies()

void BroadPhaseBruteForce::RemoveBodies	(	BodyID *	ioBodies,
		int	inNumber
	)

overridevirtual

Remove inNumber bodies in ioBodies from the broadphase. ioBodies may be shuffled around by this function.

Implements BroadPhase.
