Campaign Editor!!!!!

Im new to using the campaign editor and dont know how to make this work.

Where must I place my maps?
What is the path to load those maps? (Map1.w3x or Maps\...\Map1.w3x)

All my maps appear in blue in the campaign editor and when I save its tell me Map which are not used. How can I "use" the first map of my campaign?

Look up near the top of the campaign editor - see the tabs? You want the one called "Loading Screen." On that tab, create a button and set it to be the first map you want loaded, and be sure to check "Visible (first time campaign is loaded)" and you should be in business.

As for paths, your "Set Next Level" action should just refer to the target map by name - there's no lengthy path involved. So "Set next level to Level4.w3x" will work if you have a map called Level4.w3x in your campaign.

Good luck!
