Quick Campagin Question

If this is in the wrong place, I appologize, but there are so many forums...

Right, so... I want to make a custom campaign, but I'm a little confused concerning the heroes. Just like in Blizzard's campaigns, I want the hero the player creates in the first chapter to carry over to the second chapter (and third, fourth, etc...) is there some kind of trigger I need to do this? Or is it all covered in Blizzard's campaign editor? Thanks.

Its called a game cache, theres tutorials on it, and yes it is a trigger, accualty a large amount of triggers, i had the tutorial somewhere, but i forget where it was.

You can just search for it, "Game cache". The idea is to save everything to the cache and then load it up in the next campaign.
