Well actually I used your code just for the 3rd person
view if you don't mind.
But do you mind that I can explain my problem to you
Well I have got the player to moce his pan with the mouse force x but the mouse
force y can control the up and down movement, this is the code:

Code:

---

   
var temptilt = 0;

temptilt += 5 * mouse_force.y * time; //mouse to look up and down	
player.pan -= 20 * mouse_force.x * time;  //using the mouse to turn left and right	
camera.z=player.z+100;
camera.tilt=-10;
camera.pan = player.pan; 
camera.x = player.x - 300 * cos (player.pan) + ; 
camera.y = player.y - 300 * sin (player.pan) + ;

Any suggestions ??
