產生敵人精靈

對於我的計算項目，我需要製作某種應用或遊戲。我決定我會製造太空侵略者。我已成功地獲得基礎工作，玩家精靈會催生，我可以將它與背景和音樂工作正常，但現在當我試圖創造敵人精靈我不斷收到此錯誤：產生敵人精靈

C:\Python27\python.exe "C:/Users/Harry/Desktop/Computing Project/Galaxian.py" 
Traceback (most recent call last): 
    File "C:/Users/Harry/Desktop/Computing Project/Galaxian.py", line 87, in <module> 
    mobs.add(Mob) 
TypeError: unbound method add() must be called with Mob instance as first argument (got type instance instead) 

Process finished with exit code 1

如果任何人都可以幫助我真的很感激它！這裏是我的代碼：

TypeError: unbound method add() must be called with Mob instance as first argument (got type instance instead)

的問題是，你叫add方法和類Mob的名通過，但不是Mob一個實例。

all_sprites.add(player) 
for z in range(8): 
    mobs = Mob() 
    all_sprites.add(mobs) 
    mobs.add(Mob) # This is the class name

根據的add()界面上，你可能會想要做的：

mob = Mob() 
mobs.add(mob)

但它是一個有點不清楚你在這裏要完成

什麼
