pygame 问题

[木鱼阿呆]

import pygame
import sys

#初始化oygame
pygame.init()


screen = pygame.display.set_mode(800,800)
pygame.display.set_caption('天公')

bg = (0,0,0)

#字体显示
font = pygame.font.Font(None,20)
line_height = font.get_linesize()
position = 0

screen.fill(bg)


while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()



screen.blit(font.render(str(event),True,(0,255,0),(0,position))
position += line_height


if position > height:
position = 0
screen.fill(bg)

pygeme.display.flip()



报错在 position += line_height 怎么解决

发错版块了，需要转到哪个版块？
