Question

所以，我正在开发一个学校项目的游戏。我是Python / Pygame的新手，所以还有一些我不理解的东西。我创建了我的整个项目，没有定义函数，然后我了解了它们并将它们添加进去。自从我添加它们之后，Pygame窗口甚至都没有显示出来。怎么了？

我是StackOverflow的新手，不知道如何将其添加到代码示例中。有人可以帮我吗？感谢。

您需要调用您的函数。定义函数时，解释器不执行该代码。当您希望运行该代码块时，需要稍后调用它，例如：

>>> def main():
...     print('hi')
... 
>>> # nothing printed
... 
>>> main()
hi

通常在Python中，您将有一个语句：

if __name__ == '__main__':
    main()

这意味着如果将此文件作为主python模块调用（使用python blah.py传递给python可执行文件），则运行main()函数。 main()函数将包含完整的程序逻辑，根据需要调用其他函数。

对于您的代码，您可能需要类似（未经测试的）

if __name__ == '__main__':
    main() # initialise the window
    while True:
        mainMenu() # draw the mainMenu
        grid()     # draw the grid
        counters() # draw the counters

        # process events in this loop
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                 pygame.quit(); sys.exit();
            if event.type == pygame.KEYDOWN and event.key == pygame.K_SPACE:
                #Dice roll
                diceRoll = random.randint(1, 4)
                diceRollLabel = myFont3.render(str(diceRoll), 1, black)
                window.blit(diceRollLabel, (580, 35))
                print("Dice roll test", diceRoll)
                pygame.display.update()

不应缩进

def grid()或者应该成为grid()函数一部分的行需要缩进4个空格

为什么Python / Pygame程序没有运行？
