silverlight & C#实验成果，GDE-silverlight准备开始启动

GDE-silverlight是我和几个朋友准备在silverlight上开发一款金庸群侠传X版的游戏引擎部分。

之前一直没鼓起干劲搞，这个周末终于得空，把silverlight的几个基本功能自己动手实验了一下。基本弄明白了，准备开始鼓起干劲把GDE-silverlight完成！

感觉silverlight的UI开发还是比之前HGE好多了……之前那个呼呼累啊，梦魇~

非常简单的测试了以下几点

1. 图片加载

2. 之前部分C++代码逻辑上的移植（如寻找移动、攻击区域）

3. 地图单元格绘制

4. 动画（左上角那个爆炸是个动画。。）

5. 复用QXENGINE提供的A*寻路算法，如下图红色部分所示（它这个可以斜着寻路。。到时候需要根据具体要求改）

6. 动态加载控件（如右下的对话框）

7. 加载XML数据（可作为游戏脚本及配置文件）

接下来就是准备开始着手开始写我们的游戏引擎了。
