它不会绘制我的矩形（prdroid 上的 pygame）

Question

屏幕无法填充，它说没有屏幕填充命令，我做错了什么？

import pygame
    
pygame.init()

screen = pygame.display
set_mode((0, 0))

white = (255, 255, 255)
Square =(0, 0, 0)

loop = True
while loop:
    screen.fill(white)
    pygame.draw.rect(screen, Square, pygame)Rect(100, 100, 200, 200)
    pygame.display.update()

Answer 1

您的代码中存在一些语法错误：

~~screen = pygame.display~~
~~set_mode((0, 0))~~

screen = pygame.display.set_mode((0, 0))

~~pygame.draw.rect(screen, Square, pygame)Rect(100, 100, 200, 200)~~

pygame.draw.rect(screen, Square, pygame.Rect(100, 100, 200, 200))

不仅如此，还缺少事件循环。这可能会导致您的应用程序冻结。见 pygame.event.get() respectively pygame.event.pump():

For each frame of your game, you will need to make some sort of call to the event queue. This ensures your program can internally interact with the rest of the operating system.

正确的程序：

import pygame
    
pygame.init()
screen = pygame.display.set_mode((640, 480))

white = (255, 255, 255)
Square = (0, 0, 0)

loop = True
while loop:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            loop = False

    screen.fill(white)
    pygame.draw.rect(screen, Square, pygame.Rect(100, 100, 200, 200))
    pygame.display.update()
