Making Simple Android Game ( Sensor Moving )

// Move object using accelerometer
var speed = 10.0;

function Update () {
    var dir : Vector3 = Vector3.zero;

    // 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
    dir.x = -Input.acceleration.y;
    dir.z = Input.acceleration.x;
   
    // clamp acceleration vector to unit sphere
    if (dir.sqrMagnitude > 1)
        dir.Normalize();
   
    // Make it move 10 meters per second instead of 10 meters per frame...
    dir *= Time.deltaTime;
       
    // Move object
    transform.Translate (dir * speed);
}
