Hi everyone please help me. I want my character to jump when tilting up and to move forward vise versa of down, but i got problem with my code, the code actually jump the player automatically when played even i don't tilt it up or down.

here is my code

pragma strict

var speed : float = 6.0; var jumpSpeed : float = 8.0; var gravity : float = 10.0; private var vertVel: float = 0; // vertical velocity var moveDirection : Vector3 = Vector3.zero;

function Update () {

 // we assume that device is held parallel to the ground
 // and Home button is in the right hand
 // remap device acceleration axis to game coordinates:
 //  1) XY plane of the device is mapped onto XZ plane
 //  2) rotated 90 degrees around Y axis
 moveDirection.x = -Input.acceleration.y;
 moveDirection.z = Input.acceleration.x;
 
 // clamp acceleration vector to unit sphere
 if (moveDirection.sqrMagnitude > 1)
    moveDirection.Normalize();
    
 moveDirection *= Time.deltaTime;
        // Move object
     transform.Translate (moveDirection * speed);
     

var controller : CharacterController = GetComponent(CharacterController);

 moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
 moveDirection = transform.TransformDirection(moveDirection) * speed;

if (Input.acceleration.z != 0) { // and Jump is pressed...

if (controller.isGrounded) { // if it's grounded... vertVel = jumpSpeed;
}
} vertVel -= gravity Time.deltaTime; // apply gravity to the vertical velocity moveDirection.y = vertVel; // combine move direction with vertical velocity controller.Move(moveDirection Time.deltaTime); // and Move moveDirection = Vector3.zero;

}
