PhysicsShape.ContactFilterGroupMode.Filtering

Description

In this mode, the PhysicsShape.ContactFilter.groupIndex is used to filter if contacts are allowed to be created by the PhysicsShape.ContactFilter.categories and PhysicsShape.ContactFilter.contacts masks. The rules for two shapes coming into contact are:

• If both shapes have an identical group then the PhysicsShape.ContactFilter.categories and PhysicsShape.ContactFilter.contacts masks are used.
• If both shapes have a different group then they will never produce a contact irrelevant of the PhysicsShape.ContactFilter.categories and PhysicsShape.ContactFilter.contacts mask configuration.
• A group of zero is used like any other group but is also the default therefore if unchanged, the PhysicsShape.ContactFilter.categories and PhysicsShape.ContactFilter.contacts masks are used by default.
