Is this what you mean?I think it is possible to set the animation time so that it can be expressed

I see the code, maybe my project will work. There is such an alternative as a forced animation update by timer. But I need to find the time for each animation.
SetAnimationSpeed allows you to change the animation value added to each frame.
Setting the value to 0 will stop the animation.
