hai i just regestered here even though ive downloaded hunreds of maps and tutorials and other things from here and ive also been messing aroundw ith devmode in hugeass and i was wondering how i would be able to make a vehicle bigger ive tried
object_set_scale (unit (list_get (vehicles h5) 0) 4 000
and stuff like that but its never worked and i was also wondering how i make ai drive vehicles
i can get them in teh vehicle but i cant make them drive...so yeah please help me out n tell me some other awesome commands

Try
object_set_scale h5 4 0

YESSS thanks mate thats awesome so does anybosy know how to make the ai drive vehicles now?

You use
vehicle_load_magic -vehicle name- -"seat name"- (ai_actors -encounter name-/-squad name- )
so if you wanted to get the marines in the pelican at the start of silent catographer you use
(vehicle_load_magic insertion_pelican_2 "rider" (ai_actors beach_lz_marine/right_marine ))
Problem is they refuse to drive vehicles like warthogs, they can still sit in the vehicle though, they will get in the vehicle anyway if 'get in vehicles with player' is checked in actor tag

ok im confused but its ok i was just messing around on hugeass and i got the red_snipers to drive the hogs by converting the map to a normal halo map then changing some settings of the hog with hmtv3.5 so...yeah all fix thanks tho

actually the tags can be editted to alow the ai to drive.. they usually suck tho. I let one fly a pelican for the sake of it... they did kill some covies but they also suffered heavy loosses and crashes.
