I checked my code, found an error in the implementation, but fixing it did not help. I ran into this issue and setting Initialization(false) fixed the issue. Now the logic has changed and True is required.
Maybe this will help you somehow, I also tried to ask
directly
mix trackEntry but the result is 0.
If there are any other assumptions, I can check the implementation, maybe it's not about Spine
If you need an implementation of a class with animation control, I can provide it, but unfortunately only by mail.
