如果您真的想在 Unity 中执行此操作，您可以访问
SkeletonData.Animations，并为每个Animation 迭代Animation.Timelines并查询Timeline.Frames.length 大致相当于时间线的大小。

If you really want to do this in Unity, you could access
SkeletonData.Animations, and for each Animation iterate over Animation.Timelines and query Timeline.Frames.length which is roughly equivalent to the size of a timeline.
