SimpleCG程序交互操作_b2b160的博客-CSDN博客
之前所有示例程序都是属于展示型的,只是作为展示板输出使用,不涉及键盘和鼠标的输入交互,下面我们开始接触具有交互功能的程序。 没有交互功能的程序可以满足一定需求,不过大部分的程序是不能脱离交互功能的。程序依据使用者的操作进行相应反应并进行相关输出从而达到互动,将让程序的魅力提高一个层次。一个典型的应用就是游戏,所以学习完本篇内容后将可以进行一些游戏程序的编写。当前SimpleCG库主要支持的输入操作是鼠标和键盘,下面看看具体如何操作吧。 想要在SimpleCG中处理Windows的交互操作,就是需要定义一个消息处理函数,消息处理函数名字可以随便定义,但形式是固定的。例如鼠标消息固定形式如下所示: LRESULT OnLButtonDown( HWND hWnd, WPARAM wParam, int nX, int nY ) { } 名字OnLButtonDown是可以自己定义的,一般也是按消息功能命名。定义完消息函数后,依据想要接收的消息进行注册,所谓注册也就是调用一个设置函数。例如想要接收左键点击消息,按如下方式设置: SetMouseProcess(...
