要大大降低FPS

Question

http://www.fastswf.com/USUAp00

当我将基于perlin噪声贴图的程序生成的地图缩放到更大的尺寸时，我可以在地图上放置一个角色并实际导航它（在地图周围移动地图而不是地图上的玩家），它会导致主要的fps下降。 使用提供的链接测试自己，比例或地图宽度/高度越高，行走时滞后越多。我知道这是分配移动的数据块

有没有更好的方法来移动我的玩家？ 将生成的对象添加到对象池有帮助吗？我认为不会

是否可以在生成后将地图拆分为细分，并根据x，y？

加载某些细分

Stage Class：实际连接到舞台的类，处理帧切换

            {
                gotoAndPlay(desiredLabel);
                return;
            }
        }
        trace("Requested frame missing!");
    }
    public function generateMap(m:MouseEvent){
        GlobalCode.TILE_SIZE = int(tileSizeText.text);
        GlobalCode.MAP_HEIGHT = int(mapHeightText.text);
        GlobalCode.MAP_WIDTH = int(mapWidthText.text);

        gotoLabel("Game");
    }
    private function doneLoading(m:MouseEvent)
    {
        //set targetFrame
        gotoLabel("Menu");
    }
  }
