I'm working on the generals challenge maps making it so they work (trying my best) eg so for the air gen the new airfields fit + big air fields and new defences etc (doing for all maps) but with the toxin general i cant get him to use the upgrades for the stinger sites, Creator says i should use the code/s:
50% of team "Toxin General" perform ability "Command_UpgradeGLADefenseSiteArtileryCannon"
50% of team "Toxin General" perform ability "Command_UpgradeGLADefenseSiteTankCannon"
100% of team "Toxin General" perform ability "Command_UpgradeGLADefenseSiteRocketLauncher"
but i have no idea what file i do this in so could anyone help me out? thanks!
also any ideas for maps are welcome!
