全局名称self未定义为python

Question

嘿，伙计们，我不知道我的python/pygame游戏出了什么问题，当我尝试用IDLE 运行它时，它一直给我这个错误

Traceback (most recent call last):
  File "C:/code/gmaes/game/adad.py", line 102, in <module>
    Game().main(screen)
  File "C:/code/gmaes/game/adad.py", line 95, in main
    self.tilemap.update(dt/1000.,self)
  File "C:/code/gmaes/gametmx.py", line 689, in update
    layer.update(dt, *args)
  File "C:Python27libsite-packagespygamesprite.py", line 399, in update
    for s in self.sprites(): s.update(*args)
  File "C:/code/gmaes/game/adad.py", line 36, in update
    if self.resting and key[pygame.K_SPCAE]:
NameError: global name 'self' is not defined

我不知道为什么我会犯这个错误，我以前从来没有遇到过这个问题，我希望你们能帮忙。这是我的完整代码，看看并留下你的想法

Python游戏的主运行文件！python/pygame

哦，这是失败的代码狙击

if self.resting and key[pygame.K_SPACE]:
        self.dy = -500
        self.dy = min(400,self.dy + 40)
        self.rect.y += self.dy  * dt
        new = self.rect
        self.resting = False

在函数update()中，您忘记添加self作为第一个参数。

或者它只是slef 的一个拼写错误
