Setup this Collision node to collide as a Box. This sets the Proxy field to a simple box with given bounds. The The overloaded version with VisibleNode also sets VisibleNode as the only displayed child of this collision node. The overloaded version without VisibleNode doesn't modify the displayed children. It honors the case of Box being empty correctly. Proxy is then non-nil, but without any geometry. So the collisions are effectively disabled, in a consistent way (without changing the | |
