Python游戲無響應

Question

到目前為止，我制作這個躲閃/躲避游戲幾乎完成了，我在互聯網上的教程中添加了聲音，但是，當我嘗試運行該游戲時，當我按下按鈕進行播放時，該游戲沒有響應，但是當我按下鼠標按鈕時，會播放聲音，當我按下關閉程序的X按鈕時，游戲會運行，我不知道如何在按下任何鍵時使程序運行在我按下鼠標按鈕播放聲音的同時，這是我用來執行以下操作的以下教程（“ http://programarcadegames.com/index.php?chapter=bitmapped_graphics_and_sound 。”）這是代碼：

    pygame.display.update()
    waitForPlayerToPressKey()

    gameOverSound.stop()   

我不知道我在做什么錯，請幫幫我！ 在此方面的支持將不勝感激。

Answer 1

您有兩個while True循環-一個接一個。

第一

done = False

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True
        elif event.type == pygame.MOUSEBUTTONDOWN:
            click_sound.play()

在您單擊“ X”按鈕（ pygame.QUIT ）之前一直運行。 而且僅當您單擊鼠標時它才能播放聲音（ pygame.MOUSEBUTTONDOWN ）

刪除此循環，並while True循環中第二秒使用if/else行。
