...a trigger that makes a squad get in a m113 after i walk over the trigger...
Well, Bob, simply use a"Get in" WP for the grp, and make a "LOAD" WP for teh M113.
If ya like, you can create an "Invisible H" object and put the WP's upon it.
Then set up a trigger and hit F5 and drag a synchr. line between the WP's and between the WP's and the trigger.
And finally, hit F2 and group the trigger to YOU (player) with yet another line. This way, only YOU can fire the trigg.
(aaah, them lines.. hehehehehehe) ;D
:-X
PS.
Make it a switch trigger
PPS
The "MoveInCargo" is not so good, as it instantly teleports all of the morons into the "van".
