Execution speed is too fast, causing the animation execution sequence to change

[tcqq]

@florent37 If two different animations are executed quickly at the same time, the original execution sequence may change, resulting in is not the expected effect, I want to add a stop animation should be able to solve this problem, but I did not find the stop the animation method, can you add a stop animation method? Or how should this situation be solved?

I used this method to solve the above problem, But is there an easier way to solve the above problem?
