我正在尝试将屏幕从常规切换到全屏，但它冻结切换回常规屏幕

Question

就像标题所说的那样，我正在尝试从正常屏幕切换到全屏并返回，但它喜欢冻结，这告诉我我做错了什么或不理解某些事情。

window_width = 800
window_height = 600
black = (0,0,0)
close_program = False
fullscreen = False
import pygame
from pygame.constants import FULLSCREEN 
pygame.init()
from configuration import *

#pygame.display.set_caption("game name")
screen = pygame.display.set_mode((window_width, window_height),0 ,32)

while close_program == False:
    evnt = pygame.event.poll()
    if evnt.type == pygame.QUIT:
        close_program = True
    if pygame.key.get_pressed()[pygame.K_F5]:
        fullscreen = not fullscreen
    if fullscreen:
        screen = pygame.display.set_mode((window_width, window_height), pygame.FULLSCREEN, 32)
    else:
        screen = pygame.display.set_mode((window_width, window_height),0 ,32)

您的代码存在多个问题。最大的是你应该只在偶数到来时切换全屏。通常，您应该有一个主循环，并在其中有一个 for 循环遍历所有新事件：

while close_program == False:
    for event in pygame.event.get():
        if event.type == pygame.QUIT or (event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE):
            close_program = True
        elif event.type == pygame.KEYDOWN and event.key == pygame.K_F5:
            fullscreen = not fullscreen
            pygame.display.toggle_fullscreen()

    screen.fill(255)
    pygame.display.update()

该代码还会检查何时按下F5 按钮，然后更改fullscreen 变量的状态（此处并不真正需要）并调用pygame.display.toggle_fullscreen()。这就是你应该切换到全屏的方式。

如果toggle_fullscreen不起作用，可以尝试手动操作：

        elif event.type == pygame.KEYDOWN and event.key == pygame.K_F5:
            fullscreen = not fullscreen
            if fullscreen:
                screen = pygame.display.set_mode((window_width, window_height), pygame.FULLSCREEN, 32)
            else:
                screen = pygame.display.set_mode((window_width, window_height), 0, 32)

然而，这不太理想，对我来说不能正常工作。
