I've tried activating from a trigger, it worked, then I tried using the same trigger to activate a script, and then play the animation in the script, which worked too. So both activation method should work. The frustrating thing is that I know the script is running, it's just that the damn playmove command won't work, for some strange, annoying reason. I've even tried setpossing myself to the unit in the same script, which worked. I'll give the switchmove a try, was thinking about it yesterday, but never tried.
Well, I tried switchmove, and it works. Only problem, which was the reason why I didn't try it before, is that the transition to and from the animation looks crap. I don't really want to use switchmove rather than playmove, because playmove looks much better. I guess I can use switchmove just for now, just to get the scripting done, but in the end I need a way to get playmove to work, so any suggestions/ideas on how to get playmove to work will be welcome.
