*wistfully looks at the non-functioning Editor's Depot* :-\
In there, you'd find everything you'd need, from tutorials to scripts to annonated command reference. Since the question you're asking is a rather big one, I'm afraid. And I'm not entirely sure I get the question. Here's a reaaaally general kind of way of looking at it though:
In general, scripts come as .sqs files ; these go into the main mission folder (eg. /Users/YourUserName/Missions/YourMission.island). Once there, they can be accessed from the editor in-game.
The script in the .sqs file is executed with the command
exec, as so : [] exec "script.sqs". The stuff between the brackets [] are parameters, sometimes optional, sometimes not needed, but often necessary. So for instance the original grouplink script needed two basic parameters : the name of the group being hunted, and an array of groups doing the hunting. So it'd look like this : [MyGroup, EnemyGroups] exec "grouplink.sqs". It really has a million different uses, and I'm not going to try to write a tutorial right here, but that's pretty much the way it works. The first entry is, inside the script, accessed with
_this select 0. The second by
_this select 1, and so on. Study some scripts, and you should pretty soon figure out how it works.
Hm. Not sure if that really helps, but...well. Try to be a bit more specific, maybe? And don't worry about being new, we were all new at one point.
Cheers.
Wolfrug out.
