import pygame,sys,random

skier_images=['skier_down.png','skier_right1.png','skier_right2.png','skier_left2.png','skier_left1.png']

创建滑雪者

class SkierClass(pygame.sprite.Sprite):
def init(self):
pygame.sprite.Sprite.__init__(self)
self.image=pygame.image.load('skier_down.png')
self.rect=self.image.get_rect()
self.rect.center=[320,100]
self.angle=0

滑雪者转向

def turn(self,direction):
    self.angle=self.angle+direction
    if self.angle<-2:    self.angle=-2
    if self.angle>2:    self.angle=2
    center=self.rect.center
    self.image=pygame.image.load(skier_images[self.angle])
    self.rect=self.image.get_rect()
    self.rect.center=center
    speed=[self.angle,6-abs(self.angle)*2]
    return speed

滑雪者左右移动

def move(self,speed):
    self.rect.centerx=self.rect.centerx+speed[0]
    if self.rect.centerx<20:    self.rect.centerx=20
    if self.rect.centerx>620:    self.rect.centerx=620

创建树和小旗

class ObstacleClass(pygame.sprite.Sprite):
def init(self,image_file,location,type):
pygame.sprite.Sprite.__init__(self)

    self.image_file = image_file
    
    self.image=pygame.image.load(image_file)
    self.location=location
    self.rect=self.image.get_rect()
    self.rect.center=location
    self.type=type
    self.passed=False

#让场景向上滚
def scroll(self,t_ptr):
    self.rect.centery=self.location[1]-terrainPos
#创建一个窗口,包含随机的树和小旗

def creat_map(start,end):
obstacles=pygame.sprite.Group()
gates=pygame.sprite.Group()
location=[]
for i in range(10):
row=random.randint(start,end)
col=random.randint(0,9)
location=[col64+20,row64+20]
if not (location in locations):
locations.append(location)
type=random.choice(['tree','flag'])
if type=='tree': img='skier_tree.png'
elif type=='flag': img='skier_flag.png'
obstacle=ObstacleClass(img,location,type)
obstacles.add(obstacle)
return obstacles

有移动时重绘屏幕

def animate():
screen.fill([255,255,255])
pygame.display.update(obstacles.draw(screen))
screen.blit(skier.image,skier.rect)
screen.blit(scroe_text,[10,10])
pygame.display.flip()
#切换到场景的下一屏
def updateObstacleGroup(map0,map1):
obstacles=pygame.sprite.Group()
for ob in map0: obstacles.add(ob)
for ob in map1: obstacles.add(ob)
return obstacles
#做好准备
pygame.init()
screen=pygame.display.set_mode([640,640])
clock=pygame.time.Clock()
skier=SkierClass()
speed=[0,6]
map_position=0
points=0
map0=create_map(20,29)
map1=create_map(10,19)
activeMap=0
obstacles=updateObstacleGroup(map0,map1)
font=pygame.font.Font(None,50)
#检查案件或窗口是否关闭
while True:#开始主循环
clock.tick(30)#每秒更新30次图形
for event in pygame.event.get():
if event.type==pygame.QUIT: sys.exit()
if event.type==pygame.KEYDOWN:
if event.key==pygame.K_LEFT:
speed=skier.turn(-1)
elif event.key==pygame.K_RIGHT:
speed=skier.turn(1)
skier.move(speed)#移动滑雪者
map_position+=speed[1]#滚动场景

从场景的一个窗口切换到下一个窗口

if map_position>=640 and activeMap==0:
    activeMap=1
    map0=creat_map(20,29)
    obstacles=updateObstacleGroup(map0,map1)
if map_position>=1280 and activeMap==1:
    activeMap=0
    for ob in map0:
        ob.location[1]=ob.location[1]-1280
    map_position=map_position-1280
    map1=creat_map(10,19)
    obstacles=updateObstacleGroup(map0,map1)
#检查是否碰到树或得到小旗                              
for obstacle in obstacles:
    obstacle.scroll(map_position)
                              
hit=pygame.sprite.spritecollide(skier,obstacles,False)
if hit:
    if hit[0].type=='tree' and not hit[0].passed:
        points=points-100
        skier.image=pygame.image.load('skier_crash.png')
        nimate()
        pygame.time.delay(1000)
        skier.image=pygame.image.load('skier_down.png')
        skier.angle=0                        
        speed=[0,6]
        hit[0].passed=True
    elif hit[0].type=='flag' and not hit[0].passed:
        points+=10
        obstacles.remove(hit[0])
                              

显示得分

score_text=font.render('Score:'+str(points),1,(0,0,0))
animate()                                  

运行之后显示如下错误:
Traceback (most recent call last):
File "F:\python2.7.15\skier.py", line 85, in <module>
map0=create_map(20,29)
NameError: name 'create_map' is not defined

create_map 这个方法没定义,提示已经很清楚了

如果是没定义的话该怎么改正呢?
另外,我从网上复制的一样的程序代码,就能运行
