SetBuffer BackBuffer()
;The problem
;Run this program and hold down the cursor "right key"
;Then you see that the camera is acting like the player,
;because its a child, but that's not good because its moving,
;away from the object.
;in the tomb raider game the camera is not moving, and that's what
;i want , but its hard to make i think.
;i try to do a collions check when the camera is colli with a wall
;and then stops but that don't work for me.
;i hope you can make it
;don't need head turning or other diffec. things only the problem
;above. (only player is turning).
;THANKS VERY MUCH !!!!!
