Interface INarrowPhaseFilter

Namespace: Jitter2.Collision

Assembly: Jitter2.dll

Provides a hook into the narrowphase collision detection pipeline.

public interface INarrowPhaseFilter

Remarks

Implement this interface to intercept collisions after contact generation. This can be used to modify contact data, implement custom collision responses, or filter out specific collisions.

Methods

Filter(RigidBodyShape, RigidBodyShape, ref JVector, ref JVector, ref JVector, ref float)

Called for each detected collision with its contact data.

[CallbackThread(ThreadContext.Any)]
bool Filter(RigidBodyShape shapeA, RigidBodyShape shapeB, ref JVector pointA, ref JVector pointB, ref JVector normal, ref float penetration)

Parameters

shapeA RigidBodyShape: The first shape in the collision.
shapeB RigidBodyShape: The second shape in the collision.
pointA JVector: Contact point on shape A (modifiable).
pointB JVector: Contact point on shape B (modifiable).
normal JVector: Collision normal used to solve the contact (modifiable). A positive normal impulse pushes shape B along this direction and shape A against it.
penetration float: Signed penetration depth reported by the narrowphase. Changes to this value alone do not affect the registered contact; its separation is derived from the contact points and normal.
