this code is a fast to implement code to make a freeflight camera
It works better than the "0-key" freeflight of the engine.

Just insert the code, and start "tools_camera_freeflight1();"


Code:
  
//simple freeflight without collision detection
function tools_camera_freeflight1()
{

fps_max=80;  //limititing the framerate to overcome some calculation problems

var tools_movespeed=20;  //how fast to move
var tools_movecam[3];
var tools_cam_turnspeed=20;


while(1)
  {
  
    //turn the camera
    camera.pan-=mouse_force.x*tools_cam_turnspeed*time;
    camera.tilt+=mouse_force.y*tools_cam_turnspeed*time;
    camera.tilt=max(-90,min(camera.tilt,90));
    
    
    vec_set(tools_movecam.x,nullvector); //reset movement vector
    
    //get wasd or cursor movment
    if(key_w||key_cuu){tools_movecam.x=tools_movespeed*time;}
    if(key_s||key_cud){tools_movecam.x=-tools_movespeed*time;}
    if(key_a||key_cul){tools_movecam.y=tools_movespeed*time;}
    if(key_d||key_cur){tools_movecam.y=-tools_movespeed*time;}
    
    //rotate by camera heading
    vec_rotate(tools_movecam,camera.pan);  
    
    //move the camera
    vec_add(camera.x,tools_movecam.x);
    
    
    wait(1);
  }
}



Edit: I have inserted an FPS_Max and a timed input of mouse_force
to adjust to framerate dependencies
