第一次用Silverlight写游戏demo
话说本文4个背景。上一篇说装了XNA4.0的环境，于是还水了一篇玩模拟器的文，总觉得XNA不给力，于是想试试看silverlight写游戏会怎么样，上星期花了两个晚上试了一试，以上是第一个背景。我对游戏总是念念不忘，算是自己的梦想吧。以前写的XNA教程里从来没有提过动画的事情。最后一个原因，就是我好久没有更新博客了。
话说这个东东是按照cnblogs上注明的MVP深蓝色右手的教程写的，如果你要学习，那也许他的东西更好吧。我是很给力的想给自己的demo加上一点骚包的东西。看看实际的效果吧要不~
要不demo还是不直接贴在文章里了，跳转一下看吧：http://artorius.arthraim.com/page/sl1/
特别留意林克的眨眼，给眨眼做了个特殊的序列来实现很多重复帧的动画。另外固定的是移动时间，所以移动起来很傻吧，看着玩玩好了，貌似还有bug我三更半夜的搞得有点头大，乱的一塌糊涂，有心的谁来帮我看看？然后那啥，贴下代码吧~

就这样，结尾了！萌点在于林克~ 虽然最近很忙，不过写一个AVG游戏的念头又冒出来了。。
