then dont use the fly-through mode and instead a 18(yeah...18 ;P) line main script...

Code:

---

var video_screen=1;//fullscreen
function main
{
  fps_max=75;
  level_load("my_level.wmb");
  wait(3);
  while(1)
  {
    camera.pan -= mouse_force.x*5*time;
    camera.tilt += mouse_force.y*5*time;
    temp.x = (key_w-key_s+key_cuu-key_cud)*10*time;
    temp.y = (key_a-key_d+key_cul-key_cur)*10*time;
    temp.z = 0;
    vec_rotate(temp,camera.pan);
    vec_add(camera.x,temp);
    wait(1);
  }
}

---

(i could make the script also 5lined, but then u would have some problems to read...)
