Tutorials are there to help you learn how to create missions and campaigns. The forum is here to help when you are stuck on a tutorial, or when there is no tutorial.
There is an enormous amount of material in the Editors Depot and it does take a while to get to grips with what's there, but until you've done that - and obviously studied some of the tutes - you're not going to understand any answers given in the forum anyway. The answer to your question is well covered in the tutes to which Artak referred.
