libgdx的tmx地圖處理工具gdx-tiled-preprocessor.jar（TiledMapPacker）修正版

最近想做個Android的游戲，用到libgdx，現在研究地圖這塊，制作好地圖tmx文件后需要處理后libgdx才能載入，需要用到TiledMapPacker工具，該工具被放在gdx-tiled-preprocessor.jar里，這破玩意可愁死我了，一路嘗試下來各種各種報錯神馬的諸如：

到最后看網上別人也無解，說這玩意全是錯誤，都是用單獨的圖塊文件通過TexturePacker拼起來后得到整圖及packfile文件，然后再拿進地圖編輯器編輯以輸出tmx文件，感覺切成小圖再重新拼合挺麻煩的，就嘗試修正這個工具：

我新建了這個項目，引入了相關的jar和gdx-tiled-preprocessor.jar的源碼，在新建的Main類中的主函數里仿照原先TiledMapPacker類的主函數的調用方式調用TiledMapPacker類的功能，但是去掉了新建窗口的那部分代碼：

我真不知道這操蛋的窗口建起來是搞毛用的，里面屁也不執行，還是死活都會報錯，娘的，這是Main類的代碼：

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("待處理目錄："+inputDir+" "+inputDir.getAbsolutePath());
		System.out.println("待處理目錄："+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());
		}
	}
}

修好了窗口問題，執行起來還是有BUG，執行到TiledMapPacker類的processMap方法里就會報錯，要修改其源碼，將其中創建FileHandle的方式全部由“Gdx.files.absolute(XXX.getAbsolutePath())”改為“new FileHandle(XXX.getAbsolutePath())”形式，改好后的代碼：

	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("待處理文件："+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);
		}
	}
