Hello everyone, I want to create an animation on a map. For example, an Archangel and an Archdevil are standing there. First, the Archangel attacks, the Devil takes the hit, the Archangel is happy, then the Devil attacks, and so on. You get the idea. I tried to do it, but it didn't work. They just froze in one position and that's it...
PLEASE HELP.
