'''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. 碰撞组属性是一个字符串，用以控制一个对象与哪些对象产生的碰撞会被物理引擎处理。碰撞组与 Virtools 中由对象构成的Collision Group is ''not'' the same as the [[组group]] (Group) 并非同一概念。, as the latter is composed of objects.

如果该属性为Every collision of objects with '''空empty'''字符串，该物体与所有其他物体产生的碰撞均会被处理。Collision Groups will be processed.  Below is a list of Collision Groups of selected objects in [[Ballance]]:
