Question

我遇到了pygame的问题，谁能告诉我为什么它不显示菜单GUI？基本上，我希望它加载GUI，当我推送空间时，它选择“Play Game”并启动“Game”功能。但在它加载菜单之前，它只是简单的灰色。此外，当我击中太空时，它不会加载游戏。感谢。

BTW“游戏（）”是我以下所做的一项功能，我想加载它。

game()

Answer 1

由于您从未调用mainMenu，因此该函数中的所有代码都不会被执行。

您可以修改main功能，使其调用mainMenu（并将两个event.get()循环合并在一起，因为您只需要一个）：

import pygame, math, sys, random
pygame.init()

#Variables
darkYellow = 204,204,0
grey = 102, 102, 102
black = 0, 0, 0
white = 255, 255, 255
red = 255,0,0
marroon = 120, 0, 0
green = 0,255,0
blue = 0,0,255
darkBlue = 0,0,128

resolution = 650, 600
myFont = pygame.font.SysFont("Times New Roman", 30)
myFont2 = pygame.font.SysFont("Times New Roman", 15)
myFont3 = pygame.font.SysFont("Times New Roman", 60)

redLeft = 150, 575
redRight = 280, 575
blackLeft = 370, 575
blackRight = 500, 575
radius = 20


def mainMenu():

    rectWidth = 150
    rectHeight = 40

    #Draw buttons
    pygame.draw.rect(window, (white),(250, 150, rectWidth, rectHeight),0)
    pygame.draw.rect(window, (white),(250, 225, rectWidth, rectHeight),0)
    pygame.draw.rect(window, (white),(250, 300, rectWidth, rectHeight),0)
    highlight = pygame.draw.rect(window, (darkYellow),(250, 150, rectWidth,         rectHeight),0)
    pygame.display.update()

    playGameText = myFont.render("Play Game", 1, red)
    window.blit(playGameText, (260, 150))
    optionsText = myFont.render("Options", 1, red)
    window.blit(optionsText, (275, 225))
    exitText = myFont.render("Exit", 1, red)
    window.blit(exitText, (300, 300))
    pygame.display.update()

    while True:
        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:
                game()

def main():
    global window
    window = pygame.display.set_mode(resolution)
    pygame.display.set_caption('Harrys Game')
    mainMenu()

main()

产生您想要的菜单：

Answer 2

问题是，你打电话给你的游戏功能，绘制所有这些线，并立即返回。

然后，所有的东西都被mainMenu函数中的绘图代码所覆盖。

你最后也错过了display.update()。

要解决此问题，我会在您的游戏功能中添加另一个事件循环，并在最后进行display.update()调用。

Pygame不会立即加载菜单
