Double check if any of the next conditionals are not being triggered for lack of conditions, it sound like to two things so, first is, it's setting the animation everytick to start (from begin), or an event above is setting it to stop the animation.
To avoid one condition to start the animation everytime it's triggered, use "System|Run once while true"
Great! By using "trigger once" it does not stuck on 1st frame even if i hold atk button.
The problem is platform behavior. When on floor + moving=walk, else idle animation.
I want to be able to attack (play atk animation) while idle,walking,jumping or falling
Thank you very much!
