简介

The quickest way to constrain two objects is to select both and click the Connect button in Object ‣ Rigid Body. This creates a new empty object (named “Constraint”) with a physics constraint already attached and pointing at the two selected objects.

Also you can create Rigid Body Constraint on one of the two constrained objects with Rigid Body Constraint button of the Physics tab in the Properties. This constraint is dependent on the object location and rotation on which it was created. This way, there are no empty object created for the constraint. The role of the empty object is put on this object. The constrained object can be then set as Passive type for better driving the constrain.

Additional parameters appear in the Rigid Body Constraint panel of the Physics tab in the Properties for the selected empty object or the one of the two constrained objects with the created constraint.

Physics ‣ Rigid Body Constraint

指定在模拟过程中约束是否处于活动状态。

禁用碰撞

允许受约束的物体相互传递。

可断

允许模拟过程中将约束断开。禁用 机动 约束。可以用来模拟破坏。

阈值

通过使用限制，您可以通过制定分别在一个轴上的平移/旋转范围来进一步约束物体(请参见下面的每个轴)。要锁定一个轴，请将两个限制都设为0。

First

第一个被约束的物体。

Second

第二个被约束的物体。

允许使约束比刚体世界环境中指定的更强 (更多迭代) 或更弱 (更少迭代) 。

此约束中约束解算器在每步模拟中的迭代次数。
