Question

我正在使用 python 中的 pygame 模块编写一个简单的井字游戏，以便获得这种语言的基础知识。在编码时，我遇到了一些奇怪的事情：游戏中有四种状态： 1) 开始屏幕：这里有两个按钮：'player vs player'和'player vs cpu' 2) 'Player vs cpu' 屏幕：这里有四个按钮：简单、中等、困难、专家 3）游戏画面：游戏板将在这里 4) 最终画面：这里有一个返回主菜单的按钮

问题是当我在开始屏幕并单击“播放器与 CPU”按钮时，它会将状态更改为“播放器与 CPU”屏幕。但是，由于此状态的“专家”按钮和先前状态的“玩家 vs cpu”按钮作为位置重叠，因此它会不断将状态更改为游戏屏幕状态，而无需单击“专家”按钮。 我想不通。提前感谢您的帮助。

这是我的一些代码：

def start_screen_state(mouse, click):
    start_screen = StartScreen(gameDisplay, screenX, screenY)  # .ven bilmem ne gibi bir dosyada degisiklik yapiyormusum. ondan hata aldim
    global state # her fonk.da global olmasini istiyorsak bildiriyoruz. ilgili fonk.da artik bu degiken globaldir.
    PVPxCoord = screenX - int(screenX * 0.8)
    PVPyCoord = screenY - int(screenY * 0.4)
    PVCxCoord = screenX - int(screenX * 0.3)
    PVCyCoord = screenY - int(screenY * 0.4)
    # for PVP button
    if (PVPxCoord < mouse[0] < PVPxCoord + start_screen.get_PVP_Button().getWidth()) and (PVPyCoord < mouse[1] < PVPyCoord + start_screen.get_PVP_Button().getHeight()): #PVP butonu icin

如果我正确理解了您的代码，那么您不会在删除新屏幕之前擦除屏幕。我建议在 'pygame.display.update()' 行之前做一个 'gameDisplay.fill((0,0,0))' （不过我看不到你在其他表面上的位置）以“清理”在重绘之前。
