here it is.

 var speed=3.0;
 var rotateSpeed=3.0;
 var bulletPreFab:Transform;
 
 function Update ()
 {
     var controller:CharacterController=GetComponent(CharacterController);
 
     //Rotate around y=axis
     transform.Rotate(0, Input.GetAxis ("Horizontal")*rotateSpeed,0);
     //Move forward/backward
     var forward=transform.TransformDirection(Vector3.forward);
     var curSpeed=speed*Input.GetAxis("Vertical");
     controller.SimpleMove(forward*curSpeed);
     
     if(Input.GetButtonDown("Jump")); {
     
         var bullet= instantiate(bulletPreFab, GameObject.Find("spawnpoint").transform.position,Quaternion.identity);
     }    
     
 
 }
 
 @script RequireComponent(CharacterController)
