Yes. Actually the short climb just only not working on this side, other obstacles and the other side of this tank are works fine.Did you add the short climb animations to your animator? What ability index is set in the animator?
Ok, that's the correct ability index. Since the ability also said that it's active it does sound like it's activating correctly. Now check the animator - what state is it stuck in? What transition isn't firing to the short climb animation?
Can you check the parameter values. If the ability index of 502 is set then that means a transition isn't triggering that should be.
