I'm making a new demon race in one of my games and I wanted the Demons to have a unique lumber gathering style, so i editted a force of nature like ability to hit one tree, spawn a unit with a conversion type model and give it a negative regeneration rate. It lasts about 1/2 a second and when it dies, it adds a tree worth of lumber the the player wood pool. Problem is, trying to micro workers along with military and base operations would be a bitch, so i want to make the ability autocast like a harvest ability would
