使用一次之后，似乎释放得不干净，再用第二次之后，就会出现各种问题，就大大们指点，如何释放干净，使用完之后能还原到 未使用过的状态……

谢啦各位，最后发现原来不是没有释放干净，而是@list没有nil

直接把位图 blt 到窗口的指定位置就好了，不需要用到 sprite（也就没有了烦人的释放问题）

关于 blt，参考帮助文档的 Bitmap#blt 以及默认脚本的用法（比如绘制脸图）

国产吃货

你的脚本还是有很多差错的，比如 initialize 没必要用alias，以及善用super。

同上，太长懒得看= =

如果你最近在奋力的学脚本，可以加入下面这个讨论群（见签名档），一起学习。

太长懒得看，只说一句：

请把释放的代码写进dispose中
