I never tried it but there's a command for this...Setdir
This is what the command reference tells us :
-------------------------------------------------
Obj Setdir heading Operand types:
obj: Object
heading: Number
Type of returned value:
Nothing
Description:
Set object heading. Accepted heading range is 0 to 360.
Example:
player setDir 180
---------------------------------------------------------
So, the whole group have to turn a certain heading?
Try to name the commander (off1) and put in the getout/unload transportwaypoint (dunno what U use)
Off1 setdir 180
Maybe the commander will give the order to the whole group. It works fine with the setbehaviour... maybe with setdir too...
or :
_x "Setdir 180" foreach units grpname
Just a guess...
