nm, i've got it after playing around for a few hours lol

Code:

---

      c_move(player,move_vec,nullvector,IGNORE_PASSABLE|GLIDE);  
      
      //player.pan -= mouse_force.x*20*time_step; //old way of panning...
      c_rotate(player, vector(-mouse_force.x*20*time_step, 0, 0), 0 );

---

this seemed to correct my problems...
