various teleporter buttons in scene and on the map

Hi,

first of all I'm a newbie and not very common with scripting..

I want to place a small gui texture on the bottom of my game, that functions as a button. When I click on it, a big map should pop up with various teleporter points. I'd like to have to possibility to click on these different points on the map to teleport to the clicked point of the map in my scene. I'd like to set these points from the map in my scene as marker objects as well, so that I have the possibility to click on the point on the map or in my scene to teleport to that point..

I searched some time, but didnt't find any good advises that might help ..I've found a tutorial about teleporting but only to one different point..

So if anyone has an idea of how to manage this, or anyone has a link or tutorial or something like that, I would be very glad Maybe I only used the wrong keywords..?!?

Thanx

Olli
