RMXP - how to make a basic portal [event based please]

I am lookign for a BASIC tutorial on how to make a teleporting portal using events to make a portal to differant realms in my game.

I only use vx but I assume it works the same. Make an event that has transfer player to map[x], cool sound effect, and that's about it?

It doesn't matter what maker you use (although I'm partial to VX as well).

Just make a common event and have choices that each lead to a different location (teleport event) in it, and make anything that is going to portal you over there call that common event.

It's super easy, unless I'm not understanding what you're trying to say?

Create an event, make sure it's either player touch or action button trigger.

@>Transfer player: (choose your map)

finito.
