下面是我整理的JSFL代码，使用Flash CS4 运行此脚本，会提示你指定目录，然后该工具会将该目录下所有PNG图片，分别导出独立SWF文件，这样做，

能大大降低用户进入游戏需要加载的美术资源量的大小，降低服务器CDN带宽成本，

JSFL的使用方法，我就不介绍了，大家百度下吧，挺简单的。

fl.outputPanel.clear(); var resourcePath = fl.browseForFolderURL("请选择素材路径：");//var swfPath = fl.browseForFolderURL("请选择生成swf文件的路径：");//var rootFolderEnd = resourcePath.lastIndexOf("/");//var rootFolderName = resourcePath.substr(rootFolderEnd + 1, resourcePath.length - rootFolderEnd);//fl.trace("rootFolderName: " + rootFolderName);//var swfChildPath = rootFolderName;analyseFolder(resourcePath, "");//递归处理每个文件夹function analyseFolder(folderPath, childFolderName) {        fl.trace("文件夹: " + folderPath);        /*    if(childFolderName != "") {        swfChildPath = swfChildPath + "/" + childFolderName;        //fl.trace("创建文件夹：" + swfPath  + "/" + swfChildPath);        FLfile.createFolder(swfPath  + "/" + swfChildPath);    }    */        // 获取文件列表    var fileList = FLfile.listFolder(folderPath, "files");    for(var i = 0; i < fileList.length; i++) {        // 文件名        var fileName = fileList[i];                var filePath = folderPath + "/" + fileName;        fl.trace("文件路径: " + filePath);                var end = fileName.lastIndexOf(".");                // 如果没有后缀或后缀不正确则略过        if(end <= 0 || end == (fileName.length - 1)) {            continue;        }                // 后缀        var suffix = fileName.substr(end + 1, fileName.length - end);        suffix = suffix.toLowerCase();                // 不是PNG图片则略过        if(suffix != "png") {            continue;        }                // 不要后缀的文件名        var shortName = fileName.substr(0, end);                var dom = fl.createDocument();        var lib = dom.library;        // 导入图片        dom.importFile(filePath, true);                // 选择项        lib.selectItem(fileName);                if(lib.getItemType() == "bitmap"){            // 使用photo(JPEG)压缩            lib.compressionType="photo";            lib.quality = 80;                 // 使用文档的压缩质量，可在导出时设置            lib.useImportedJPEGQulity = true;         }                lib.selectItem(shortName);        lib.setItemProperty("linkageImportForRS", false);        lib.setItemProperty("linkageExportForAS", true);        lib.setItemProperty("linkageExportInFirstFrame", true);        lib.setItemProperty("linkageBaseClass", "flash.display.BitmapData");        lib.setItemProperty("linkageClassName", "IMG_" + shortName);                // 放到舞台上        /*        lib.addItemToDocument({x:0,y:0});        dom.selectAll();        dom.convertToSymbol("movie clip",shortName,"top left");        lib.selectItem(shortName);        lib.setItemProperty("linkageImportForRS", false);        lib.setItemProperty("linkageExportForAS", true);        lib.setItemProperty("linkageExportForRS", false);        lib.setItemProperty("linkageExportInFirstFrame", true);        lib.setItemProperty("linkageIdentifier", shortName);        dom.selectAll();        dom.deleteSelection();        */                //var createSWFPath = swfPath  + "/" + swfChildPath;        //fl.trace("createSWFPath: " + createSWFPath + "/" + shortName + ".swf");                dom.exportSWF(folderPath + "/" + shortName + ".swf", true);        // 是否保存fla 文件        //fl.saveDocument(dom, folderPath + "/" + shortName + ".fla");        dom.close(false);    }        // 子文件夹    var folderList = FLfile.listFolder(folderPath, "directories");        for(var j = 0;j < folderList.length; j++) {        var childFolder = folderList[j];                fl.trace("文件夹: " + resourcePath + ", 子文件夹: " + childFolder);                 // 递归调用        analyseFolder(folderPath + "/" + childFolder, childFolder);    }}
