Pygame转换/按钮不会产生持续变化

Question

我正在尝试创建一个游戏，在你点击正确答案后，一个动画出现，并出现“恭喜”或“再试一次”。但是，动画不起作用，文字只在我按下按钮时出现。我该怎么解决这个问题？在

我尝试将所有代码放入while循环中，但这导致游戏窗口根本没有响应。在

Answer 1

根据变量woah绘制结束符号。你设置了woah = 10，游戏的每一次迭代。在

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会重置，因此不会绘制结束符号。你必须在游戏开始前设置woah，而不是在循环中。在

为了完成@Rockybilly的答案，当然必须在主循环之前初始化变量woah。使用^{} statement访问函数mathGame2中的变量。在

但同样重要的是，在文本必须绘制到显示器后执行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()
