python贪吃蛇游戏运行时窗口黑屏_Pygame窗口显示空白黑屏

问题：缩进误差

您的game_intro()函数已定义，但从未调用

您写了gameDisplay而不是screen4次，也用display_width, display_height代替{}

在game_intro()中，不调用无限循环后的代码

pygame.display.update(screen)不起作用，应该pygame.display.update()来更新整个屏幕。flip(screen)还需要更改为flip()

函数text_objects()没有定义，但我在您可能从中复制代码的示例中找到了该定义：)

更正代码：import sys

import pygame

from pygame.locals import *

pygame.init()

size = width, height = 720, 480

speed = [2, 2]

black = (0,0,0)

blue = (0,0,255)

green = (0,255,0)

red = (255,0,0)

screen = pygame.display.set_mode(size)

pygame.display.set_caption("BETA::00.0.1")

clock = pygame.time.Clock()

def text_objects(text, font):

textSurface = font.render(text, True, black)

return textSurface, textSurface.get_rect()

def game_intro():

screen.fill(blue)

largeText = pygame.font.Font('freesansbold.ttf',115)

TextSurf, TextRect = text_objects("BETA", largeText)

TextRect.center = ((width/2),(height/2))

screen.blit(TextSurf, TextRect)

pygame.draw.rect(screen, green,(150,450,100,50))

pygame.draw.rect(screen, red,(550,450,100,50))

pygame.display.flip()

pygame.display.update()

clock.tick(15)

intro = True

while intro:

for event in pygame.event.get():

print(event)

if event.type == pygame.QUIT:

pygame.quit()

quit()

game_intro()
