所以我差不多用C ++和SDL编写了我的第一个tic tac toe，ad我遇到了一个小问题。我使用状态机从标题屏幕切换到形状选择屏幕，一个或两个播放器到获胜屏幕并返回到选择屏幕等。在选择屏幕上，我有两个SDL_Rect阵列作为按钮，按钮是我在我的精灵表中使用的X和O精灵。当鼠标悬停在它们上面时，它们会改变颜色。一切都很好，花花公子，直到比赛失败或平局后游戏重置到选择屏幕。当它返回到选择屏幕并且鼠标悬停在按钮上时，它不显示之前剪切的突出显示或鼠标悬停的精灵。我把这个问题指向我的“set_grid_regions（）”函数的初始化。但是这个数组甚至不会以任何方式与选择屏幕类进行交互。这怎么会影响我的悬停精灵？
所以任何人都可以看到，这是整个程序：

这很奇怪。但我99％确定它是“set_grid_regions（）”，它影响了choice :: render（）或choice :: event（）类fucntions中的渲染。任何人都可以帮忙吗？
答案 0 :(得分：0)
导致剪辑问题的错误是sprite_clip的错误声明。你已经宣布它为sprite_clip[10]，但你有13个精灵。将其更改为sprite_clip[13]。
我注意到的其他事情：
new分配所有这些状态对象，但绝不会delete它们。当你改变状态时，你需要delete他们。否则你会泄漏内存。font.ttf似乎是一种全球资源，但是由全局和本地方法的混合物随意管理。在load_files()中加载一次，然后在clean_up()中将其释放一次。虽然您的项目可能已完成，但您可能会对其进行修补，并在您有所工作的情况下继续改进实施。 （如果这是一个家庭作业，请保留一份工作版本的副本。;-)）
init_xxx和load_xxx函数将移至其构造函数。你的clean_up移动到它的析构函数。playerOne和playerTwo合并为一个类。在施工时区分它们，就像使用win(0)，win(1)，win(2)一样。
