i have made this script but i am getting an error that i dont understand
Assets/scripts/movement.js(5,21): BCE0018: The name ‘Vector3.zero’ does not denote a valid type (‘not found’).
the error changes if i move the character motor script around
here is the script thats getting the error:
#pragma strict

var MoveSpeed : float = 50;
var JumpSpeed : float = 55;
var MoveDirection : Vector3.zero;
var Gravity : float = 45;
var JumpActive : boolean = false;


function Start () {

        if( JumpActive ){
           MoveDirection = new Vector3(Input.GetAxis("Horizontal"), 0 , Input.GetAxis("vertical"));
           MoveDirection = transform.TransformDirection(MoveDirection);
           MoveDirection *= MoveSpeed;
        
        }
        }
        if( JumpActive ){
        if( Input.GetKey(KeyCode.Space)){
           MoveDirection.Y = JumpSpeed;
        
        }
                MoveDirection.Y -= Gravity * Time.deltaTime;
        var Controller = GetComponent(CharacterController);
        var Flags = Controller.Move( MoveDirection * Time.deltaTime);
           JumpActive = (Flags & CollisionFlags.CollidedBelow) !=0;
}

function Update () {

}

Line 3 should read:

var MoveDirection : Vector3 = Vector3.zero;

Also Vector3’s use lower case letters for x,y,z.
