I followed a tutorial i am sure i have exactly what he had except for the name but i keep getting this error "Assets/Galaxy_Quest/Scripts/s_HUD.js(12,43): BCE0017: The best overload for the method 'UnityEngine.Object.FindObjectOfType(System.Type)' is not compatible with the argument list '(s_mainCharacter)'." here is my code for both files:

*s_mainCharacter*

    static var SPEED = 7; 
    static var TURBO = (SPEED *2);
    var rotateSpeed = 3.0;
    var bullitPrefab:Transform;

    var pHealth : int;
    var pScore : int;
    var pLife : int;
    var pPower : int;

    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 bullit = Instantiate(bullitPrefab, GameObject.Find("leftSpawnPoint").transform.position, Quaternion.identity);
        var bullit = Instantiate(bullitPrefab, GameObject.Find("rightSpawnPoint").transform.position, Quaternion.identity);
        bullit.rigidbody.AddForce(transform.forward * 2000);
    }

}

function damageTaken(totalDamage : int){
    pHealth -= totalDamage;
    if(pHealth <= 0){
        if(pLife <=0){
            killPlayer();
        }
            else {
                pLife --;
            }
    }

}

function killPlayer(){
    print("YOU DIED");
}

function addScore(totalScore : int){
    pScore += totalScore;
}

function getStatus(send : int){
    switch (send){
        case 1:
            return pLife;
            break;
        case 2:
            return pHealth;
            break;
        case 3:
            return pPower;
            break;
        case 4:
            return pScore;
            break;          
    }
}
