Question

JavaScript => public var useContactForce: bool;
C# => public bool useContactForce;

Description 描述

Should the impulse force but applied to the contact point?

该冲击力是否只用于接触点？

When true, the force is applied to the contact point which may cause the target to rotate. When off, the force is applied to the center-of-mass, therefore no rotation is produced.

当该属性为true，该力用于可能导致目标旋转的接触点。当关闭时，该力应用于该对象的重心，并且不会产生旋转。
