Question

我正在制作一个2D游戏并且我在地图上停留。我希望它存储在像这样的文本文件中

[block name] [x] [y]
wall 20 20

wall 20 40

wall 20 60

wall 20 80

wall 20 100

wall 20 120

wall 20 140

wall 20 160

wall 20 180

wall 20 200

我有一个读取该代码的代码

       public void TileLayer() throws IOException{
       InputStream inp = (InputStream) getClass().getResourceAsStream("/image/msdf.txt");
    BufferedReader in = new BufferedReader(new InputStreamReader(inp));
    String str;
    while ((str = in.readLine()) != null) {
           if (str.startsWith("wall ")) {
         float x = Float.valueOf(str.split(" ")[1]);
         float y = Float.valueOf(str.split(" ")[2]);

           }
    }

   }

但比如何展示呢？如何缓冲它？

感谢您的帮助。如果您有任何问题，我会问，我会回答。
