Question

我有这个项目用主菜单创建游戏。我现在创建了一个非常基本的主菜单，仅用于原型目的。我的主菜单加载，然后我想点“f”来玩游戏，但它没有像希望的那样工作。当我启动它时，我在添加功能之前很好，但我需要这些功能。有人有任何想法吗？感谢。

mainMenu()


pygame.display.update()

Answer 1

一些事情：

main_menu()有一个while True:循环，没有break，raise或return，因此如果有人调用则会无限循环。

game()包含一个永不启动的while False:“循环”。

这条线毫无意义：

mainMenu() == False

并且也不会：

game() == True

出于某种原因，您定义了函数（例如def counters:），然后立即调用它们（例如counters()）。

当您运行代码时，会发生这种情况：

def main():之前的所有定义都会发生;
main定义然后立即调用;
mainMenu已定义;
game，但不执行任何操作（参见上文）;
counters;和
您致电pygame.display.update()。

就是这样。永远不会调用mainMenu（这是一件好事，因为它永远无法循环）。

伪代码建议：

set up variables

set up window 

main menu:
    setup on screen text
    while True:
        get user input 
        if correct user input:
            break
    call game

game:
    while True:
        play game

call main menu

Python / PyGame函数没有像希望的那样工作
