Question

我正在尝试创建一个游戏，在其中单击正确的答案后，会出现动画，并出现“恭喜”或“重试”字样。但是，动画不起作用，并且仅当我按下按钮时才会显示文字。我该如何解决？

我试图将所有代码放入while循环中，但这导致游戏窗口完全不响应。

Answer 1

要完成@Rockybilly的答案，当然必须在主循环之前初始化变量woah。使用global statement访问函数mathGame2中的变量。

但是同样重要的是在必须将文本绘制到显示之后执行pygame.display.update()：

def mathGame2():

    global woah

    # [...]

    if game2 == 0:

       # [...]

       #woah = 10 <----- delete 

       # [...]

       # pygame.display.update() <---- delete

       if woah == 1:
            win.blit(congrats, (200, 500))
            while ybox > 400:
                ybox += 10
                win.blit(skybox, (xbox, ybox))
            game2 += game2
        if woah == 0:
            win.blit(again, (200, 500))

        pygame.display.update()

woah = 10
run = True
while run:
    #Quit game
    pygame.time.delay(100)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    mathGame2()

Answer 2

您可以根据变量woah绘制结尾符号。然后，在游戏的每次迭代中都设置woah = 10。

if game2 == 0:
    win.blit(divQ1, (200, 200))
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    woah = 10  # Here!

因此，当您不按按钮时，woah将被重置，因此不会绘制结尾符号。您必须在游戏开始之前而非循环中设置woah。

Pygame过渡/按钮无法创造持久的变化
