Character Flight

[system]

I have been trying to find/make a character controller & script that give my player the ability to fly but nothing is working… could someone help me out please? (I’d really apprieciate it)

[system]

This is my latest attemp but this one along with the others dont work that well

function Update () {
}

//Speed Variable unstable above 25

var speed = 6.0;

var airspeed = 5.0;

var jumpSpeed = 8.0;

var gravity = 20.0;

private var moveDirection = Vector3.zero;

private var grounded : boolean = false;

function FixedUpdate() {

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;

     }

   }

   else {

   //Preserving fall value

   var fall = moveDirection.y;

   var NewmoveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));

   NewmoveDirection = transform.TransformDirection(NewmoveDirection);

   moveDirection = moveDirection + ((NewmoveDirection * airspeed) * Time.deltaTime);

   //Replacing Y movement value to original fall

   moveDirection.y = fall;

   }

// Apply gravity

moveDirection.y -= gravity * Time.deltaTime;

// restrict to speed and Move the controller

moveDirection.x = Mathf.Clamp(moveDirection.x, -speed, speed);

moveDirection.y = Mathf.Clamp(moveDirection.y, -speed, speed);

moveDirection.z = Mathf.Clamp(moveDirection.z, -speed, speed);

var controller : CharacterController = GetComponent(CharacterController);

var flags = controller.Move(moveDirection * Time.deltaTime);

grounded = (flags & CollisionFlags.CollidedBelow) != 0;

}

@script RequireComponent(CharacterController)
