使用MFC做贪吃蛇小游戏

1、先启动vs2013 -- >新建项目 -->选择一个MFC应用程序 -->填上名称以及项目的位置 -->确定2、在应用程序向导中选择基于对话框的应用程序 -->完成。3、在资源视图中，把向导为我们生成的控件删掉。4、然后按F5运行一下程序。运行结果如下。一个空白的对话框。5、下面就要开始在这个对话框上面制作我们的游戏界面了！首先，我们需要做一下游戏界面的规划，在这里代码部分讲解初始化贪吃蛇起初有3个节点，长度为3，起始坐标;     食物默认为 1无0有 当然我更加喜欢0无1有*/void CMFC_SNAKEView::OnInitialUpdate(){CView::OnInitialUpdate();Snake[0].x = 10;Snake[0].y = 10;Snake[1].x = 11;Snake[1].y = 10;Snake[2].x = 12;Snake[2].y = 10;Snake[0].direct = 3;Snake[0].len = 3;Food.isfood = 1;// TODO: Add your specialized code here and/or call the base class}
