虽然我不是动画师，但这通常不是通过在动画期间更改父子关系来实现的，而是通过两个变换约束并将混合值在第一个约束中从 0 切换到 1，在第二个约束中从 1 切换到 0。 这样，骨骼将跟随第一个或第二个目标，可以在动画中间更改。

While I am not an animator, this is typically achieved not by changing parent-child relationship during animation, but having two transform constraints and switching the mix value from 0 to 1 on the first constraint and from 1 to 0 in the second constraint. This way a bone will follow either the first or the second target, which can be changed mid-animation.

我不知道你为什么这么想，因为使用变换约束取放武器是一个常见的用例。事实上，我们以前在博客上发布过一个类似案例的教程。:

你能更详细地描述一下你正在寻找的结果吗？

I'm not sure the reason why you think so, because taking or putting a weapon using transform constraints is a common use case. In fact, we have posted a tutorial for a similar case on our blog before:

Could you describe in more detail about the results you are looking for?
