I'm having an issue and I have no idea why this is happening and how to fix it. I'm working on developing a Videogame with python and pygame and I'm getting this error:
File "/home/matt/Smoking-Games/sg-project00/project00/GameModel.py", line 15, in Update
self.imageDef=self.values[2]
TypeError: 'NoneType' object has no attribute '__getitem__'
The code:
import pygame,components
from pygame.locals import *
class Player(components.Entity):
def __init__(self,images):
components.Entity.__init__(self,images)
self.values=[]
def Update(self,events,background):
move=components.MoveFunctions()
self.values=move.CompleteMove(events)
self.imageDef=self.values[2]
self.isMoving=self.values[3]
def Animation(self,time):
if(self.isMoving and time==1):
self.pos+=1
if (self.pos>(len(self.anim[self.imageDef])-1)):
self.pos=0
self.image=self.anim[self.imageDef][self.pos]
Can you explain to me what that error means and why it is happening so I can fix it?
BrenBarn is correct. The error means you tried to do something like None[5]
. In the backtrace, it says self.imageDef=self.values[2]
, which means that your self.values
is None
.
You should go through all the functions that update self.values
and make sure you account for all the corner cases.
