Important q: laser designator

[Rubble_Maker]

I'm having serious trouble with the laser designator; I need to make it a *fixed* weapon so the gunner cannot move the laser spot anymore (this I need to predict in which direction the laser beam will point so I can use triggers to detect the laser ammo).

So the prob is: How can I disable the lock-onto-target feature of a weapon? So far I tried these, without success:

   canLock=false;
   airLock=false;
   laserLock=false;
   irLock=false;
   manualControl=false;
   enableAttack=0;
