我无法在python 3.7.7中用pygame画一个圆圈

问题描述

我一直在寻找文档,YouTube上的许多视频,关于stackoverflow的问题,但仍然无法解决。这是我的代码

import pygame
pygame.init()
run = True
#color def
BK = (0,0)
WT = (255,255,255)
GY = (127,127,127)
#create screen
screen = pygame.display.set_mode((800,600))
#title,icon
pygame.display.set_caption("Clock")
icon = pygame.image.load("clock.png")
pygame.display.set_icon(icon)
#loop
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
pygame.draw.circle(screen,WT,(0,0),175,width=1)

解决方法

您错过了通过pygame.display.update()pygame.display.flip()来更新显示的信息。并且您需要在应用程序循环中绘制圆圈。关心Indentation

while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
   
    #-->|  INDENTATION

    # clear display
    screen.fill(0)

    # draw scene (circle)
    pygame.draw.circle(screen,WT,(0,0),175,width=1)

    # update display
    pygame.display.flip()
