Godot Version
4.7
Question
Hello, I’m getting started with Godot and made a playground to get to understand basics of game development with Godot. I created a character with animations imported from Mixamo and was able to display properly IDLE, RUN, ATTACK, now I tried to add a run animation so the character don’t snap to the new direction but now my other animations are not being show. I see that the blend values go close to 1 for the nodes but I’m stuck moving in IDLE and since I’m not firing the attack animation if I click (attack) the signal for finishing the attack animation is not being fired resulting in a loop that prevents for any other input.
I’'ll provide my player code, my animationTree and I don’t know what else is useful to resolve this like I said I’m totally new to Godot and to game development. Thanks
Animation Tree
Animation Tree Parameters
My player script, I created an Enum that used inside of function handle_animations() updated the run_val and turn_val to be shared with update_tree() there’s a bunch of commented print’s that I was using to debug but the one that is throwing me off is that I see the values coming close to one in this one print("run val: %s, turn val: %s" % [run_val, turn_val])

Hope that you can help me, I’m Argentinian so sorry if my wording in english is confusing.
Cheers, thanks in advance.
