function ChipmunkBegin_type1_type2(arbiter : ChipmunkArbiter) : bool
| arbiter | The arbiter for this collision. |
bool - A boolean specifying whether the collision between these two shapes should be ignored. If ignored, the separate method will be called, but the pre/post solve methods will not.
Called on the first fixed time step that two shapes with the given @ChipmunkShape.collisionType@s begin colliding.
The primary purpose of this function is to allow for efficient collision events and filtering if you only care about the initial collision between two shapes.
