doTeleport()

    self endon ( "disconnect" );
    self endon ( "death" );
    self notifyOnPlayerCommand("N", "+actionslot 1");

    for(;;)
    {
        self waittill( "N" );
        self beginLocationSelection( "map_artillery_selector", true, ( level.mapSize / 5.625 ) );
        self.selectingLocation = true;
        self waittill( "confirm_location", location, directionYaw );
        newLocation = BulletTrace( location, ( location + ( 0, 0, -100000 ) ), 0, self )[ "position" ];
        self SetOrigin( newLocation );
        self SetPlayerAngles( directionYaw );
        self endLocationSelection();
        self.selectingLocation = undefined;
    }
}

This is the code for teleport, press N for activating it in game.
