一个带 角发动机 的物理约束将会旋转,但细节在于它 如何 旋转。 Driven by Velocity (由速度驱动)的角发动机将会应用一个约束力,从而"旋转",而 Driven by Position (由位置驱动)的角发动机会基于弹簧尺寸和应用于该弹簧的阻尼来获取角度。

另外有一点可能大家还不完全了解,实际上旋转的是约束本身,而不是对象,但由于对象之一没有进行物理行为的模拟,所以它强制其它目标进行了移动。 尝试对红色立方体启用 Simulate Physics (模拟物理行为)以观察它是如何四处翻滚的。

对红色立方体启用 Simulate Physics (模拟物理行为)会造成它在整个房间内运动。

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
