I want to play custom games against computers but whenever I start the games the computers just sit there, they don't play the game. Help please?
Isn't there a setting for game difficulty or AI difficulty. Also if it's a map you or someone else made they may have made the comp players = passive. I haven't played wc3 for a long time though so..
If the AI doesn't do anything, they haven't been programmed into the specific map. Try playing the default maps that come with the game, and if nothing works reinstall the game completely, to fix the AI issue.
