// 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;
