The repeat won't work. It's going to run that in one tick, so you'll never see the result. You'll need a timer to simulate the animation running, or turn on the animation, with something else to stop each after 9 frames.
Hey blackhornet
Why the "repeat" event is not work?
I need to change the frame of each one of the instances per time. I really need a timer and I thought that the "repeat" would do this, or in other words: pick all the instances with non-zero frame and create an order using the UID number and then change the frame of each one at a time.
