also, i dont think this site approves of resources that use unapproved resources. i dont think PullUnit is approved here so this spell might not be admitted for that. maybe you should get that admitted first or 'sneak it in' by putting the code in that library in library of the spell.
That doesn't count as another resource, it's just part of the spell! It isn't released anywhere...
Anyway, thanks for the feedback. I'll turn off the collision like you suggested.
Weird, I can't seem to be able to disable the units' collision. I couldn't work out how to make the unit's movement type flying - I don't think it's possible - and SetUnitPathing(u, false) didn't work. I also tried giving the unit the ghost (visible) ability but that also failed. Any ideas anyone?
