java - 在哪里添加 AtlasTmxMapLoader 的 atlas 属性

Question

我正在重构我的游戏，我想使用 AltasTmxMapLoader 来提高 TiledMaps 的渲染性能。我坚持将 map 集属性添加到 map 中。例如，我需要将其放在这张 map 的哪里？

<?xml version="1.0" encoding="UTF-8"?>
<map version="1.0" orientation="orthogonal" width="10" height="10" tilewidth="32" tileheight="32">
 <tileset firstgid="1" name="tile2" tilewidth="32" tileheight="32">

 </tileset>

  <tile id="129">

   </properties>
  </tile>
  <tile id="161">

    <property name="move" value=""/>
   </properties>
  </tile>
 </tileset>
 <tileset firstgid="1537" name="trees" tilewidth="32" tileheight="32">
  <image source="trees.png" width="512" height="512"/>
 </tileset>
 <tileset firstgid="1793" name="trees2" tilewidth="32" tileheight="32">

我已经尝试过将其添加到 map 标签和图 block 集标签中，但这不是正确的解决方案。我已经注意到，我需要将图集放入与 tmx 文件相同的文件夹中，但我真的想知道在哪里放置标签。

这并不像将 atlas 属性放入源那么简单。

不会使用该属性，因为 xml 中描述的图 block 根本不引用图集。

你需要的是让TiledMapPacker运行你的文件。它将预处理您的 map 、创建优化的图集文件并将属性添加到 xml 中。只有这样您才能使用 AltasTmxMapLoader 正确加载该文件。

参见my posts here了解我如何让它发挥作用的解释。

libgdx 官方发行版中的工具应该包括所有必要的东西。我用这个命令运行它:

java -classpath "gdx.jar";"gdx-natives.jar";"gdx-backend-lwjgl.jar";"gdx-backend-lwjgl-natives.jar";"gdx-tools.jar";"gdx-tiled-preprocessor.jar" com.badlogic.gdx.tiledmappacker.TiledMapPacker "processed/input" "processed/output" "--strip-unused"

要从代码运行它，请将其放在核心主类/项目中:

    Settings settings = new Settings();
    settings.maxWidth = 2048; //modify if needed
    settings.maxHeight = 2048; //modify if needed
    settings.fast = true; //fast should be fine here!
    //all tiles have a 1px padding. better for not getting artifacts
    TiledMapPacker pack = new TiledMapPacker();
    try
    {
        pack.processMaps(
                new File(
                        "PATH-TO-INTPUT"),
                new File(
                        "PATH-TO-OUTPUT"),
                settings);
    }
    catch (IOException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
