package com.badlogic.gdx.graphics.g2d.tiled; 文件TileAtlas:            当 libgdx使用tiled Map时，由于原方法获取图块是通过配置的图片packfile来获取的，用于我找不到生成图片packfile的工具，所以打算修改这个方法，直接不需要packfile就可以操作(一个方法优化可以少生成一个packfile文件),以下是原始方法：   public TileAtlas (TiledMap map, FileHandle inputDir) {         // TODO: Create a constructor that doesn't take a tmx map,         for (TileSet set : map.tileSets) {             FileHandle packfile = getRelativeFileHandle(inputDir, removeExtension(set.imageName) + " packfile");             TextureAtlas textureAtlas = new TextureAtlas(packfile, packfile.parent(), false);             List<AtlasRegion> atlasRegions = textureAtlas.findRegions(removeExtension(removePath(set.imageName)));             for (AtlasRegion reg : atlasRegions) {                 regionsMap.put(reg.index + set.firstgid, reg);                 if (!textures.contains(reg.getTexture())) {                     textures.add(reg.getTexture());                 }             }         }     } 修改为：通过算数来算出值，而不是通过packfile文件读取，package file读取可能会产生很多问题。 public TileAtlas (TiledMap map, FileHandle inputDir) {          for (TileSet set : map.tileSets) {               if(set.imageName==null){                 continue;             }             FileHandle imageFile = getRelativeFileHandle(inputDir, (set.imageName) );              List<AtlasRegion> atlasRegions=new ArrayList<AtlasRegion>();             Texture texture = new Texture(imageFile);             for(int j=0;j<texture.getHeight()/set.tileHeight;j++){                 int wn=texture.getWidth()/set.tileWidth;                 for(int i=0;i<wn;i++){                     AtlasRegion atlasRegion= new AtlasRegion(texture,i*set.tileWidth,j*set.tileHeight,set.tileWidth,set.tileHeight);                     atlasRegion.index=j*wn+i;                     atlasRegions.add(atlasRegion);                 }             }             for (AtlasRegion reg : atlasRegions) {                 regionsMap.put(reg.index + set.firstgid, reg);                 if (!textures.contains(reg.getTexture())) {                     textures.add(reg.getTexture());                 }             }         }     }     我这里有一个demo，截图如下   代码如下：   package com.zx;
