最近做页游项目,需要将人物跑动的序列帧切成最小以提高程序效率,于是我写了这个小程序。

protected function CutButton_clickHandler(event:MouseEvent):void
{
/* 新建文件夹 */
if(!_selectedFolder)
return;

_fileList = new Array();

var temp:Array = _selectedFolder.getDirectoryListing();
for (var i:uint = 0; i < temp.length; i++)
{
if(!temp[i].isDirectory){
var afterfix:Array = (temp[i].name as String).split(".");
if(afterfix[afterfix.length-1] == "png")
_fileList.push(temp[i]);
}
}

if(_fileList.length>0){
_curPicIndex = 0;
_loadPng = new LoadPng();
_cut = new CutAction();
addEventListener("finish",nextCut);
progressBar.visible = true;
cutButton.enabled = false;
fileSystemTree.enabled = false;
_saveFolder = _selectedFolder.resolvePath("new");
_saveFolder.createDirectory();
nextCut();

}
}

感谢伟大的GFW，本博客已迁至饭桶VPS~

VHD不是仅仅用来装系统，其他地方照样可以用。比如童鞋们玩的魔兽世界喜欢被病毒感染客户端，我们就可以用VHD来保护我们的客户端。

首先创建VHD，格式化，并将客户端拖入其中。

diskpart
Creste vdisk file=D:\game\wow.vhd type=fixed maximum=20000
Select vdisk file=D:\game\wow.vhd
Attach vdisk
Exit

复制文件吧。。。半个小时后回来。。。

diskpart
Select vdisk file=D:\game\wow.vhd
detach vdisk
create vdisk file=”D:\game\wow_temp.vhd” parent=”D:\game\wow.vhd”
Exit

工作做完了，下面是我做好的批处理，童鞋们修改下路径就可以用了。

开机启动.bat

rem 我要玩WOW…
echo select vdisk file=”D:\game\wow_temp.vhd” >> “D:\game\wow.txt”
echo attach vdisk >> “D:\game\wow.txt”
diskpart /s “D:\game\wow.txt”
del “D:\game\wow.txt”

我的客户端被感染了，我要还原！.bat

rem 卸载wow_temp.vhd并将之删除
echo select vdisk file=”D:\game\wow_temp.vhd” >> “D:\game\wow.txt”
echo detach vdisk >> “D:\game\wow.txt”
diskpart /s “D:\game\wow.txt”
del “D:\game\wow_temp.vhd”
del “D:\game\wow.txt”
rem 创建新wow_temp.vhd并加载
echo create vdisk file=”D:\game\wow_temp.vhd” parent=”D:\game\wow.vhd” > “D:\game\wow.txt”
echo select vdisk file=”D:\game\wow_temp.vhd” >> “D:\game\wow.txt”
echo attach vdisk >> “D:\game\wow.txt”
diskpart /s “D:\game\wow.txt”
del “D:\game\wow.txt”

我要更新我的客户端！.bat

rem 更新客户端中，请勿浏览神马神马电影网站。。。
echo select vdisk file=”D:\game\wow.vhd” >> “D:\game\wow.txt”
echo attach vdisk >> “D:\game\wow.txt”
diskpart /s “D:\game\wow.txt”
del “D:\game\wow.txt”

更新完了.bat

rem 我更新完了，我要上线做日常…
del “D:\game\wow_temp.vhd”
echo select vdisk file=”D:\game\wow.vhd” >> “D:\game\wow.txt”
echo detach vdisk >> “D:\game\wow.txt”
echo create vdisk file=”D:\game\wow_temp.vhd” parent=”D:\game\wow.vhd”>> “D:\game\wow.txt”
echo select vdisk file=”D:\game\wow_temp.vhd” >> “D:\game\wow.txt”
echo attach vdisk >> “D:\game\wow.txt”
diskpart /s “D:\game\wow.txt”
del “D:\game\wow.txt”
