Hi.
I'm not sure I use the right term. I need the next mechanism. For example:
I'm animating a hero in a game. I use Unity as an engine. In Spine I've done 2 animations: walk simple and walk upstairs. In a game I should do the next: my hero walks on the ground than walks on some stairs and walk on the ground again.
When he walks on the ground I use spine for animate his legs and hands in walk cycle (he stands on the same X in Spine) but I move him on X axis in Unity. But when I want to do animation where he walks upstairs I can't move him on X in Unity. So I have to do it in Spine. So, on the first frame and the last frame of animation he has different X.
How can switch between animations smoothly if some of them in Spine has stable coordinates of the main hero bone but some has changing?
