Space Flying Script Using Mouse

Question

So I made this script that works quite well for flying around in space like conditions. I getting quite sick of having to use my keyboard for all the movement functions though. Is their any way I have swap out pitch and yaw for mouse controls?

Here's the script:

private var pilot : Rigidbody;

var invertPitch : boolean = true; var invertYaw : boolean = false; var sensitivity : float = 1.0;

function Start () { pilot = GameObject.FindWithTag("Player").rigidbody; thrustEmitter = GetComponentInChildren(ParticleEmitter); thrustEmitter.enabled = false; } function Update () { // Did the user press fire? if (Input.GetButton ("Fire1")) BroadcastMessage("Fire");

 if (Input.GetKeyDown("w"))
 {
     SetThrust(500);

 }

 if (Input.GetKeyUp("w"))
 {
     SetThrust(0);

 }

 if (Input.GetKeyDown("s"))
 {
     SetThrust(-300);    

 }

 if (Input.GetKeyUp("s"))
 {
     SetThrust(0);
 }

 if (Input.GetKeyDown("a"))
 {
     SetRoll(20);    

 }

 if (Input.GetKeyUp("a"))
 {
     SetRoll(0);

 }

 if (Input.GetKeyDown("d"))
 {
     SetRoll(-20);   

 }

 if (Input.GetKeyUp("d"))
 {
     SetRoll(0);

 }

     if (Input.GetKeyDown("i"))
 {
     SetPitch(15);

 }

 if (Input.GetKeyUp("i"))
 {
     SetPitch(0);

 }

 if (Input.GetKeyDown("k"))
 {
     SetPitch(-15);  

 }

 if (Input.GetKeyUp("k"))
 {
     SetPitch(0);

 }

     if (Input.GetKeyDown("j"))
 {
     SetYaw(5);  

 }

 if (Input.GetKeyUp("j"))
 {
     SetYaw(0);

 }

 if (Input.GetKeyDown("l"))
 {
     SetYaw(-5); 

 }

 if (Input.GetKeyUp("l"))
 {
     SetYaw(0);

 }

function SetThrust ( thrustForce : int) { pilot.constantForce.relativeForce = Vector3.forward  thrustForce  sensitivity; }

function SetRoll (rollForce : int) { pilot.constantForce.relativeTorque = Vector3(0,0,1)  rollForce  sensitivity; }

function SetPitch (pitchForce : int) { if(invertPitch) { pilot.constantForce.relativeTorque = Vector3.right  pitchForce  sensitivity; } else { pilot.constantForce.relativeTorque = Vector3.left  pitchForce  sensitivity; } }

function SetYaw (yawForce : int) 
{ if(invertYaw) { pilot.constantForce.relativeTorque = Vector3(0,1,0)  yawForce  sensitivity; } else { pilot.constantForce.relativeTorque = Vector3(0,-1,0)  yawForce  sensitivity; }

}

You could check the Input.mousePosition every frame (in the Update() function), store it in a variable, and if it differs from the previous frame, alter the thrust/roll accordingly. (This would be the equivalent of WASD)

private var previousMousePosition : Vector3; // Where you store the previous mouse position

function Update()
{
    if (Input.mousePosition.x - previousMousePosition.x != 0) // Check for horizontal change
    {
        SetRoll((Input.mousePosition.x - previousMousePosition.x)  500);
    }
    if (Input.mousePosition.y - previousMousePosition.y != ) // Check for vertical change
    {
        SetThrust((Input.mousePosition.y - previousMousePosition.y)  300);
    }

 previousMousePosition = Input.mousePosition; // Set the current mouse position for the next frame

This is untested code, so it might not work, but you get the general idea. :)
