"When unit enters region"

"When unit enters region"

Hey guys and girls! I got a problem. I'm making a little ugly RPG thingy. But i got a problem. Your caratcher must enter a kind of gateway to get to one of the areas. However i don't use gateways, but i can't find some command thingy in triggers that says something like "When unit enters region" he goes there and there.

And i got alittle question: For future RPG projects, how do you make those systems there are in every RPG/ORPG where you choose a hero??

THanks in advance

"a unit enters teleport" (teleport is the name of the region)

"move triggering unit instantly to center of teleportdestination" (teleportdestination is the name of the other region where you want the hero to be teleported to, like in gateways.)
