简易版3D中国象棋
在前面几篇博客了简要的介绍了一下WPF相关的技术，其中主要是3D编程和鼠标事件在3D环境中的相关处理。通过上面的学习，我来讲一下基于上述技术做的一个没有AI的类3D中国象棋。
1. 游戏界面的编写，首先使用viewport3D这个控件来建立一个3D的场景，其中有camera，ModelVisual3D。然后在ModelVisual3D的content属性上使用了Model3DGroup，最后在这个group中加入一些3D模型，比如光源，一些GeometryModel3D（这个是有material和MeshGeometry3D组成的）。其实上面讲的这些是一颗树的关系，大家可以用笔画一下就知道了，其实在WPF中写界面程序，每个程序都是一个tree的概念，一层套一层。
2. 棋的规则的实现，这个问题是游戏的核心问题。我使用了一个二维matrix来代替棋盘，给每个棋子起了标示（比如一个正整数），在matrix中放上对应的数字就可以的。当有棋子移动的时候，在matrix上也相应的移动，如果它的移动式去吃棋子，这时候就会在matrix中原来的地方变为没棋的状态，而在它吃棋的地方放上他的标示，然后在棋盘上删去被吃的棋子；如果他只是移动的，就只要在matrix的原来的地方变为没棋的标示，在移动到的地方放上这个标示。这其中还有就是你移动棋子的合法性判断，这个也完全可以通过matrix来判断，比如说“车”，只要判断它到目的地之间没有其他棋子就好了，也就是只要判断matrix中间全部都是没棋的状态。
3. 联系界面和matrix的是鼠标事件，主要使用的技术就是hittest技术，可以在我们的前面的博客中知道怎么使用。鼠标事件主要分为三种.1)选中要移动的棋子，使用左键选择棋子，对其合法选中的棋子进行记录和改变其外观。2)取消刚才选中的棋子，使用右键取消刚才选中的棋，让其恢复到原来的样子。3)选要移动的目标，如果没有违反棋的规则，就移动到目的地。
我的游戏是在windows7和visual studio 2010上编译生成的。
程序很长：
