How do I limit map and teleport to another map?

I wanted to create rpg with mysterious story but i cant find a way to make my character to teleport different map like traveling to towns or entering house (just like pokemon/lufia/zelda)

Not to try and put you off or anything but I should warn you that this is the least of your problems if you are planning to make an RPG as a new user, they are very complex. To teleport to a different map you are basically going to a new layout in C2. Each map would be on a different layout and you use 'go to layout X', you would create or spawn the player in the new layout, or the player could be a global object and you set the position of the player.

Thanks man...
