Constant Force With x,y,z Movement

Hello Dear Friends,


First of all , i want to create a space flight game and in this game my ship should move constantly to the one direction. Moreover, while my ship goes to its way i have to control my ship in 3d dimension with my mouse. I tried several things im not a professional coder so i need some help with this kind of script. I found constantForce script and some Mouse Controller Script from the forum but i couldnt combine them together. ( Ship has to be Rigidbody)

I found this for Mouse Controller :

var force : Vector3;
var relativeTorque : Vector3;


function Start() {
Screen.lockCursor = true;
}

function FixedUpdate() {
// Turn
var h = Input.GetAxis("Mouse X");
var v = Input.GetAxis("Mouse Y");

rigidbody.AddRelativeTorque(0, h * 20, v * 20);

}


And this one is for ConstantForce :

var force : Vector3;
var relativeTorque : Vector3;
var liftSpeed : float;
var turnSpeed: float;

function Start () {

}

function Update () {
if (Input.GetButtonDown("Fire1")) {

constantForce.force= Vector3.forward * liftSpeed;


As i said if i only use constant force it is okay when i click to game ship goes its way but i cannot control it . On the other hand when i try to embed this code to mouse control script nothing happens. If possible i need some help.
Thanks,

 

Instead of using constantForce try to use Rigidbody.velocity

So can i implement the mouse axis codes into this one ? i really need help with this combination
