1. bring up the 3rd layer again and right click where u want to the hero to enter and select "place Teleport Event" then you come up with a screen where you select where you want to reappear
2. now if u want to make it look good (say like make the screen zoom in as you enter and zoom out as you leave) after you have made the teleporting event double click on it to bring up the event editor for it and where it says " <>hide screen: use default" right click that and select edit you then can choose what happens when you enter now click ok after u have chosen it and do the same for "show Screen: use delfault"
