Scripts

Open the map file with an archiver, go to /maps/singlemission_or_multiplayer/map_name/. Open the map.xdb file with Notepad, find the line <MapScript href=""/> and change it to <MapScript href="MapScript.xdb#xpointer(/Script)"/> and save. Add the MapScript.xdb file to the same folder with this:

<?xml version="1.0" encoding="UTF-8"?>
<Script>
	<FileName href="MapScript.lua"/>
	<ScriptText/>
</Script>

And the MapScript.lua file, into which you need to write the script.
