小甲鱼老教程82讲 pygame
import pygameimport sys
from pygame.locals import *
# 初始化pygame

bg = (255, 255, 255) #RGB
fullscreen = False
# 指定窗口大小
screen = pygame.display.set_mode(size, RESIZABLE)
# 设置窗口标题
pygame.display.set_caption("初次见面，请大家多多关照！")
# 设置放大缩小的比率

# 加载图片
oturtle = pygame.image.load("2.jpeg")

# 图像移动
position = position.move(speed)
if position.right > width :

speed =
if position.bottom > height:

position.top = height - turtle_height
speed = [-5 , 0]
if position.left < 0:
turtle = turtle_left
position = turtle_rect = turtle.get_rect()
position.top = height - turtle_height
speed =
if position.top < 0:
turtle = turtle_top
position = turtle_rect = turtle. get_rect()
speed =
# 填充背景
screen.fill(bg)
# 更新图像
screen.blit(turtle, position)
# 更新界面
pygame.display.flip()
# 延迟10毫秒
pygame.time.delay(10)
第82行中
if position.bottom > height:
turtle = turtle_bottom
position = turtle_rect = turtle.get_rect()
position.left = width - turtle_rect.width
position.top = height - turtle_height
speed = [-5 , 0]
小甲鱼在视频中写的是这个，但是明明turtle_height没有定义，为什么他的可以运行而我的不可以 1、82 行 是 turtle_buttom 不是 turtle_bottom
2、85、91行 是 turtle_rect 中的 height 属性，不是 turtle_height
参考代码：

# 设置窗口标题
pygame.display.set_caption("初次见面，请大家多多关照！")
# 设置放大缩小的比率
ratio = 1.0
# 加载图片
oturtle = pygame.image.load("2.jpeg")
turtle = oturtle
# 获得图像的位置矩形
oturtle_rect = oturtle.get_rect()
position = turtle_rect = oturtle_rect
speed =
turtle_right = pygame.transform.rotate(turtle, 90)
turtle_top = pygame.transform.rotate(turtle, 180)
turtle_left = pygame.transform.rotate(turtle, 270)
turtle_buttom = turtle
l_head = turtle
r_head = pygame.transform.flip(turtle, True, False)
while True:
