Collision Group

Chinese version / 中文版:	碰撞组

Collision Group is a property of physicalized objects in Virtools, which is a string used for controlling which collision of the specified object and other objects will be processed by the physics engine. Collision Group is not the same as the group, as the latter is composed of objects.

Collisions of two objects with the same Collision Group will not be processed by the physics engine, meaning that they will pass through each other on "collision".

Every collision of objects with empty Collision Groups will be processed.

Below is a list of Collision Groups of selected objects in Ballance:
