Pygame window 在点击之前运行正常，然后显示 "Not responding"

Question

先说几件事：

我用的是Windows10家庭版
我正在使用 Python 3.7
我正在使用 pygame 1.9.4
我的IDE是Visual Studio代码，以IDLE为备份

我目前正在使用 pygame 设计 GUI。注意：代码尚未完成。

当我在 VS Code 中运行调试会话时，它（大部分）按预期工作，但是当我尝试单击开始按钮时，pygame 没有响应并显示没有响应.

我在我制作的其他 pygame 脚本中也注意到了这一点，其中 pygame window 在单击或移动时冻结。

如有任何帮助，我们将不胜感激。

代码如下：

# Import modules
import sys, pygame, time, math
from time import sleep
from PIL import Image

# Display background image
image = 'asdf.png'
change = 2
img = Image.open('asdf.png')
width = img.width * change
height = img.height * change
print(width)
print(height)
screen = pygame.display.set_mode((width,height))
background = pygame.image.load(image).convert()
newscreen = pygame.transform.scale(background, (width, height))
screen.blit(newscreen, (0,0))
pygame.display.update()

# start button
pygame.draw.rect(newscreen, (255,120,0), pygame.Rect(width/4,height-height/4, width/2, height/7))
screen.blit(newscreen, (0,0))
pygame.display.update()
pygame.init()
myFont = pygame.font.SysFont("Times New Roman", 100)
text = myFont.render("START", False, (0, 0, 0))
screen.blit(text, (width/4+8,height-height/4-10))
pygame.display.update()
pygame.image.save(newscreen, 'background.png')
pygame.image.save(text, 'starttext.png')

# i button
pygame.draw.rect(newscreen, (255,0,120), pygame.Rect(width - 50, 10, 40,40))
screen.blit(newscreen,(0,0))
pygame.display.update()
myFont = pygame.font.SysFont("Times New Roman", 25)
ibutton = myFont.render("i", False, (0, 0, 0))
screen.blit(ibutton, (width-32,17))
pygame.display.update()

# Mouse click
while True:
    left,right,center = pygame.mouse.get_pressed()
    if left == True:
        if event.type == MOUSEBUTTONUP:
            x,y = pygame.mouse.get_pos()
            if ((width/4) <= x <= ((width/4) + (width/2))) and ((height-height/4) <= y <= ((height-height/4) + height/76)):
                #move to next screen
                break

time.sleep(5)

这与链接的问题不相似，因为我的程序是用于 GUI 的，它需要鼠标单击事件。

Ted Klein Bergamn 的回答解释了为什么 window 变得无响应：

pygame.event.get 应该这样使用：

running = True
while running:
    for event in pygame.event.get():
        # This lets you quit by pressing the X button of the window.
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONUP:
            if event.button == 1:  # 1 = left mouse button, 2 = middle, 3 = right.
                print('mouse up')
                x,y = pygame.mouse.get_pos()
                if ((width/4) <= x <= ((width/4) + (width/2))) and ((height-height/4) <= y <= ((height-height/4) + height/76)):
                    #move to next screen
                    running = False

在您的情况下（对于简单的 GUI 应用程序）pygame.event.wait 可能是一个不错的选择（它让程序在队列中没有事件时休眠）。

running = True
while running:
    event = pygame.event.wait()
    if event.type == pygame.MOUSEBUTTONUP:
        if event.button == 1:
            print('mouse up')
            x,y = pygame.mouse.get_pos()
            if ((width/4) <= x <= ((width/4) + (width/2))) and ((height-height/4) <= y <= ((height-height/4) + height/76)):
                #move to next screen
                running = False
