CollisionGroup

Sets collision group membership and filter masks on an entity's physics colliders using a bitmask. Two colliders collide only when (a.membership & b.filter) ~= 0 AND (b.membership & a.filter) ~= 0.

Public fields: membership (default 0xFFFFFFFF), filter (default 0xFFFFFFFF).

Methods: setGroups(membership, filter), ignoreEntity(entityId, ignore?).

entity(id).component.add("CollisionGroup", { membership = 1, filter = 3 })
