I do not mean auto acquire. I want to have Attack as a single use ability. As in, my Marine shoots once when it is used. If I want him to shoot again, I use it again. I refrained from posting here in case it was easy to find, but I've looked through everything I could think of that could possibly relate to this, and have not found anything. I tried searching for it, but I only found people talking about auto target acquiring.
I do not want to use triggers to make my unit stop firing. This should be possible with just the Data editor.
