Thanks Deadfast!! it runs ok.
Another trouble, now I want to order a group of IA to "MoveToCargo", the problem is that IA disapear and apear in vehicle as cargo.
I tried:
_x moveinCargo _vehicle;
_x action ["getInCargo", _vehicle];
and
_x action ["moveToCargo", _vehicle];
but two first moves instantly, and the last, _x action ["moveToCargo", _vehicle]; does nothing.
How can i do for the IA moves to vehicle and then gett in it?
