1.EasyTouch事件：On Move(Vector2 v)

當Camera不為Vector.zero時，會導致人物移動看起來不是正對攝像機，需要做一個轉換：

//以Camera正方向為準，轉換目標座標

pos = Quaternion.LookRotation(new Vector3(camera.transform.forward.x, 0, camera.transform.forward.z)) * pos;

    public Transform camera;
    Transform player;
    Vector3 pos;
    public void MoveInJoyStick(Vector2 inputPos)
    {

        if (inputPos.y != 0 || inputPos.x != 0)
        {
            if(camera==null)
            {
                camera = Camera.main.transform;
                if (camera == null) return;
            }
            if(player == null)
            {
                player=GameObject.Find(NetData.GetUnitData(AccountInfo.UUID, AccountInfo.char_uid).nickname).transform;
                if (player == null) return;
            }
            pos = new Vector3(inputPos.x, 0, inputPos.y );
            //以Camera正方向為準，轉換目標座標
            pos = Quaternion.LookRotation(new Vector3(camera.transform.forward.x, 0, camera.transform.forward.z)) * pos;
            pos = new Vector3(player.position.x + pos.x, player.position.y, player.position.z + pos.z);
            //同步位置
            UIMgr.GetAssetInfo().MycharController.CmdTouchProcess(pos);
        }
    }
