Spaceship is not shooting

[nosymmetree]

I cannot make the spaceship shoot the laser

[nosymmetree]

in playerController.js:

var laserPrefab:Rigidbody;

    //fire at left apple key
    if(Input.GetKeyDown(KeyCode.LeftControl)){

        //create a bullet at th position of the spaceship
        Instantiate(laserPrefab,transform.position,transform.rotation);
        //the laser shot counter 
        laserShots++;
        //audiosource for the laser being shot
        GetComponent(AudioSource).clip = laserSounds[ Random.Range(0,laserSounds.Length)];
        GetComponent(AudioSource).Play();

    }
