Python 为什么我的代码在打开时总是退出*在游戏中*

下面是我试图在pygame中制作的一个游戏的代码。我试图运行它来测试它，但每当我按下“玩游戏”按钮时，它就会退出。这很奇怪，我试着检查也许我在游戏功能中做错了什么，但我似乎找不到任何东西。我打开了规则，规则似乎运行得很好，退出游戏按钮也是如此。为什么“玩游戏”按钮会出现这种情况，我是否遗漏了什么

如果backRect.collidepoint（mx，my）：
draw.rect（屏幕、黑色、背面、3）
如果按钮==1：
返回状态_菜单#在函数drawGame中，您有：

state = drawScoreboard(screen, mx, my, button)

您不小心用记分板重新定义了状态。为drawGame函数使用以下代码，您的游戏应按预期运行

def drawGame(screen, button, mx, my, state):
    global player
    scoreboardHeight = height //5
    draw.rect(screen, blue, (0, 0, width, height))
    draw.rect(screen, black, (0, 0, width, height), 2)
    drawScoreboard(screen, mx, my, button)

    draw.circle(screen, light_pink2, player, 10) 
    draw.circle(screen, black, player, 12, 1)
