Hello, you are absolutely right, i didnt know that, but actually my original script use switchmove previous to playmove, I have made some other test and i realize that the switchmove/playmove combination works for Eden Editor placed units but not for script crated units, in this last case only the switchmove is executed. Bellow is a part of my script, none of the playmove works on script created units. I use the createvehicle command for create the unit.
