I'm trying to make something that turns your enemy into ally and then you must click to attack. However, this will not work because the unit acts like he's shooting the person but never actually does.
Help me please.

changing alliance status interrupts any current attack commands, unless the enemy doesn't change alliance status. Stop changing or setting the alliance status on hyper triggers.

Oh I see, problem solved . Sometimes Starcraft can be annoying ... and also, it says Starcraft isn't a word. lol
