You must understand.........

F2 is for mapping only. It is for making the map from scratch or editing a map that has been made by someone else, like adding buildings to it.


F3 is a separate working area, for adding entities like soldiers and other stuff, and scripting how the mission will run.

F3 is what the others refer to as the script part of the map.

The F2 map file gets saved by itself, and in it's own map folder ,

and the F3 script or mission files get made separately.
