Hello all,
I am working on a 3D arcade shooter project and I have ran into a bump earlier than I would have liked. I had my AnimationTree filled with Blend2s and it was working with all the values I obtained in this model. I have since moved to the BlendSpace2D and cannot seem to figure out why my animations are not playing correctly in game. The blends work well in the preview, but are not so hot in the game once compiled.
Before looking at the code (which is for a character controller), here are some need to knows:
Walking forward require the tree to be at (0, 1)
Left (-1, 0)
Right (1, 0)
Idle (0, 0)
And naturally I want them blended for a natural look --- Thanks in advance to anyone that might be able to help.
