Campaign Map Transfer

I know how to make maps transfer like in the Bonus Campaign in TFT. But i don't know how to make them work in a campaign, cuz you have to specify the map location to switch to it, and the Bonus Campaigns works cuz it is in the MPQ archive which sets the common directory. Any help?

you need to use the game save/load natives, it is actually pretty complex.

Maybe this could help a bit?

I looked at the demo campaign and it showed me that maps in a campaign have no directory, so just the map name will transfer it within the campaign.

thanx anyway guys!
