libgdx的tmx地图处理工具gdx-tiled-preprocessor.jar（TiledMapPacker）修正版

最近想做个Android的游戏，用到libgdx，现在研究地图这块，制作好地图 tmx文件后需要处理后libgdx才能载入，需要用到TiledMapPacker工具，该工具被放在gdx-tiled- preprocessor.jar里，这破玩意可愁死我了，一路尝试下来各种各种报错神马的诸如：

到最后看网上别人也无解，说这玩意全是错误，都是用单独的图块文件通过TexturePacker拼起来后得到整图及packfile文件，然后再拿进地图编辑器编辑以输出tmx文件，感觉切成小图再重新拼合挺麻烦的，就尝试修正这个工具：

我 新建了这个项目，引入了相关的jar和gdx-tiled-preprocessor.jar的源码，在新建的Main类中的主函数里仿照原先 TiledMapPacker类的主函数的调用方式调用TiledMapPacker类的功能，但是去掉了新建窗口的那部分代码：

我真不知道这操蛋的窗口建起来是搞毛用的，里面屁也不执行，还是死活都会报错，娘的，这是Main类的代码：

package com.skyd.tiledmappacker; import java.io.File; import java.io.IOException; import com.badlogic.gdx.tiledmappacker.TiledMapPacker; import com.badlogic.gdx.tools.imagepacker.TexturePacker.Settings; public class Main { /** * @param args */ public static void main(String[] args) { File tmxFile, inputDir, outputDir; Settings settings = new Settings(); // Note: the settings below are now default... settings.padding = 2; settings.duplicatePadding = true; TiledMapPacker packer = new TiledMapPacker(); if (args.length != 2) { System.out.println("Usage: INPUTDIR OUTPUTDIR"); System.exit(0); } inputDir = new File(args[0]); outputDir = new File(args[1]); System.out.println("待处理目录："+inputDir+" "+inputDir.getAbsolutePath()); System.out.println("待处理目录："+outputDir+" "+outputDir.getAbsolutePath()); if (!inputDir.exists()) { throw new RuntimeException("Input directory does not exist"); } try { packer.processMap(inputDir, outputDir, settings); } catch (IOException e) { throw new RuntimeException("Error processing map: " + e.getMessage()); } } }

修好了窗口问题，执行起来还是有BUG，执行到TiledMapPacker类的processMap方法里就会报错，要修改其源码，将其中创建 FileHandle的方式全部由“Gdx.files.absolute(XXX.getAbsolutePath())”改为“new FileHandle(XXX.getAbsolutePath())”形式，改好后的代码：

 

public void processMap (File inputDir, File outputDir, Settings settings) throws IOException { FileHandle inputDirHandle = new FileHandle(inputDir.getAbsolutePath()); File[] files = inputDir.listFiles(new TmxFilter()); for (File file : files) { System.out.println("待处理文件："+file+" "+file.getAbsolutePath()); map = TiledLoader.createMap(new FileHandle(file.getAbsolutePath())); for (TileSet set : map.tileSets) { if (!processedTileSets.contains(set.imageName)) { processedTileSets.add(set.imageName); packTileSet(set, inputDirHandle, outputDir, settings); } } writeUpdatedTMX(outputDir, map.tmxFile); } }

 

然后导出为Runnable JAR file：

注意入口选择Main类。

 

修正好之后的测试环境：

在in目录里放置素材图片和地图编辑器生成的tmx文件：

命令行执行：

D:\test>java -jar TiledMapPacker.jar in out

out目录将得到处理后的文件：

至此就搞定了，可以在libgdx里进行渲染了。

 

修正后的TiledMapPacker.jar下载：
