I might be missing something here, but it sounds like you’re describing a simple branch statement? I assume there is some code set up when you click a card. You can set a bCardInteracting boolean to true when this happens and to false when you let go of the card and use this for a branch after the input events. Or is the card setup to complicated for this to work somehow?
Ok, then perhaps you can help me figure out where the issue is, since I have not been able to replicate it. Can you give me the precise steps you have done before this happens? How do you create your anim class? Is is a duplicate or child component? What code do you add to it and how, and have you made any other changes?
