用vs2019做了一个2048小游戏,鼠标操作被键盘操作阻塞无法运行

0

问题出在了while循环里面,我的猜想是因为键盘控制影响了鼠标操作,当不进行键盘操作时,就会停在keyDeal这一步,此时无法进行鼠标操作。因此我试着给keyDeal加了判定(现在的代码里面没加):if(_kbhit()),顺利解决了鼠标操作没用的问题。但是另一个问题就是当加了判定之后,就会一直进行gameDraw这一步,造成了闪屏现象。因此我想知道如何解决这一问题,使绘制既能正常运行,也能让鼠标操作生效

用的是VS2019!

keyDeal() 整个函数阻塞了,导致 mou() 没有及时执行。

应该先用 _kbhit() 判断是否有按键,如果有,再执行 keyDeal()。这样,就能让主循环一直跑起来。同时,你需要给主循环加一个 Sleep,避免 CPU 占用率过高。

再创建一个线程专门接收鼠标消息
