Spinebot
Thank you very much for your reply. According to your tips, I got the answer to the question in the example of "Spine Examples/Other Examples/FixedTimestepUpdates".
skeletonAnimation.Update(deltaTime);
skeletonAnimation.LateUpdate();
skeletonAnimation.enabled = false;
The animation can be updated, but the deltaTime needs to be large enough to update to the target action. I guess this has something to do with the mixing of the animation. The above code can directly switch to other animations when closing the script.
