Hello, i have problem with Ladder script. No error, but i can’t climb up. I chatch on ladder but i can’t climb up 
. Please how to do it?
Code for walking
var speed = 6.0;

private var controller : CharacterController = null;
private var onLadder = false;
var ladderHopSpeed = 6.0;

mainCamera = GameObject.FindWithTag("MainCamera");
controller = GetComponent(CharacterController);
}
function FixedUpdate() {
// *** Added for UseLadder ***
// If we are on the ladder, let the ladder code take over and handle FixedUpdate calls.
if(onLadder) {
gameObject.SendMessage("LadderFixedUpdate", null, SendMessageOptions.RequireReceiver);
return;
}

if (grounded) {
// We are grounded, so recalculate movedirection directly from axes
moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
if (Input.GetButton ("Jump")) {
moveDirection.y = jumpSpeed;
}
}
// Apply gravity
moveDirection.y -= gravity * Time.deltaTime;
// Move the controller
var flags = controller.Move(moveDirection * Time.deltaTime);
grounded = (flags CollisionFlags.CollidedBelow) != 0;

// perform off-ladder hop
var hop : Vector3 = mainCamera.transform.forward;
hop = transform.TransformDirection(hop);
moveDirection = (ladderMovement.normalized + hop.normalized) * ladderHopSpeed;
}
