Big noob Need to know how I can make that

I want my fps camera to teleport to another scene when it press a button.

Let's put it like this. I've got a house, I want the character to be teleported to another scene (that will be the house interior) when he presses a button of my choice in front of the door.

Can someone tell me how can i do taht on script or even better! to give me the whole script, because Im seriously a great noob, I've search for a very long time what command lines I should use but i didnt find any!

PLEASE HELP ME!

There are an awful lot of things your asking for here. Try to focus your questions in the future. Focus on one aspect of your implementation at a time.
