The game only regards a slot as a computer if it actually is a computer e.g its set that way in Player Properties or it is added in a user slot when playing in wc3
now the only thing that troubles me is: i cant get the hang of importing models! i followed the import model tutorial but still no work! i want to use the kitabatake model. EDIT: i put in a countdown trigger but it doesn't work right.
