恐怕目前还没有简单的方法在Skeleton UI元素上使用MecanimAnimator。你需要对UI元素使用SkeletonGraphic(它是将 AnimationState 作为 SkeletonAnimation)。
I'm afraid currently there is no simple way to use a Mecanim Animator on a Skeleton UI element. You need to use SkeletonGraphic (which is using AnimationState as SkeletonAnimation) for UI elements.
你可以看看 Spine Examples/Other Examples/StateMachine SkeletonAnimation 中的 Mecanim Logic SkeletonAnimation View 示例场景,它展示了你如何将一个Mecanim Animator的状态转发到一个 SkeletonAnimation 的 AnimationState。然而这需要一些额外的编码来适应 SkeletonGraphic。所以这很可能对你需要实现的目标来说太复杂了。
You could have a look at the Mecanim Logic SkeletonAnimation View example scene in Spine Examples/Other Examples/StateMachine SkeletonAnimation, it shows how you can forward a Mecanim Animator's state to a SkeletonAnimation's AnimationState. This would however require some additional coding to adapt to SkeletonGraphic. So this is most likely too complex for what you need to achieve.
