根据操纵杆输入移动GameObject

Question

我想根据操纵杆的输入来移动游戏对象，而将手机固定在横向模式下。

以下是我的代码，

  selectedGameObject.transform.forward = new Vector3(joyStick.Horizontal, 0f, joyStick.Vertical);

  if(joyStick.Direction.y > 0)
  {
      selectedGameObject.transform.Translate(new Vector3(joyStick.Horizontal * 0.01f, 0.0f, joyStick.Vertical * 0.01f));
  }
  if (joyStick.Direction.y < 0)
  {
     selectedGameObject.transform.Translate(new Vector3(joyStick.Horizontal * 0.01f, 0.0f, -joyStick.Vertical * 0.01f));
  }

不幸的是，游戏对象奇怪地移动，有时以相反的方式移动。我想念什么？
