I'm also having trouble with this. Thought It was simple but Doesn't seem to be working for me. Thought I'd try and get a walk anim going before I got it to move.
Got sprite anim 'Run' with frames 0 - 9 at speed of 12 on loop with 0 repeat count.
Event sheet says 'keyboard - right arrow is down - set anim to "run" (play from beginning)
this wouldn't work so added Start animation from beginning
also have keyboard on right arrow released - stop animation.
Any IdeaS?
