Python AttributeError: 'module' has no attribute 'currentanimation'

Question

I have some code in main.py:

import pygame, char
def move(char):
    #movement code
    #friction
    if char.xaccel == 0:
        if abs(char.xvel) < char.xvelfalloff: char.xvel = 0
        elif abs(char.xvel) == char.xvel: char.xvel -= char.xvelfalloff
        elif abs(char.xvel) != char.xvel: char.xvel += char.xvelfalloff
    #acceleration
    char.xvel += char.xaccel
    #max speed
    if abs(char.xvel) > char.xmaxvel: char.xvel = math.copysign(char.xmaxvel,char.xvel)
    #position/collision detection
    char.x += char.xvel
    char.xaccel = 0
    char.yaccel = char.ygravity
    char.yvel += char.yaccel
    char.y += char.yvel
    if char.y < 0: #TODO: more collision detection
        char.yvel = 0
        char.y = 0
        char.onground = True
    if char.jumping:
        char.yvel = char.jumpstrength
        char.jumping = False
        char.onground = False
    #no more movement code
charObj = char.Char()
charObj = move(charObj)
screen.blit(char.currentanimation, pygame.Rect(char.x, (screen_height-char.y)-char.height, char.width, char.height))
pygame.display.flip()

and some code in char.py:

import pygame
class Char(): 
    spritesheet = pygame.image.load("images/spritesheet.png")
        walkanim = []
        for i in range(7):
            spritesheet.set_clip(pygame.Rect(((sprite_width-7)*i)+3,12,sprite_width,sprite_height))
            spritesheetsubsurface = spritesheet.subsurface(spritesheet.get_clip())
            walkanim.append(pygame.transform.scale(spritesheetsubsurface, (width, height)))

        spritesheet.set_clip(pygame.Rect(0,577,sprite_width,sprite_height))
        spritesheetsubsurface = spritesheet.subsurface(spritesheet.get_clip())
        idleanim = pygame.transform.scale(spritesheetsubsurface, (width, height))
        lastanim = "right"

        currentanimation = idleanim
        animationframeindex = 0
        animationframepause = 6 #how many frames go by between animation frames
        animationframetime = 0 #how many frames we have been on the same animation frame

Note that I've cut out everything unrelated here. So, I get an error when I run this code that says:

Traceback (most recent call last):
  File "C:\Users\spng453\scripts\super smash feminist\main.py", line 90, in <module>
    screen.blit(char.currentanimation, pygame.Rect(char_x, (screen_height-char_y)-char_height, char_width, char_height))
AttributeError: 'module' object has no attribute 'currentanimation'

I literally have no idea where I could have gone wrong here. Any help with understanding where this problem stems from would be appreciated.

If the answer ended up being the correct, would you mind marking the question as resolved? — sgarza62, Aug 30 '14 at 02:58

If you define a class to have an attribute (ie, self.currentanimation), you can access it like so:

charObj = char.Char()
charObj.currentanimation

What you're doing in your code is looking inside the module char, not inside your instance of Char (charObj). The char module has no attribute/variable/etc named currentanimation. But instances of Char do – or, rather, they will once you define an __init__() method in your class definition, and start using self :-)

For more on setting and accessing attributes, take a look at this section of the docs.

Wow, I'm surprised I let that through. Thanks! – Aearnus Aug 30 '14 at 01:35
So if I got this right, I have to make all of those variables reference to, for example, `self.currentanimation` instead of `currentanimation`? Also sorry, it wouldn't let me edit my last post. – Aearnus Aug 30 '14 at 01:41
I'm having another problem though, once I make all the variable declarations reference `self.`..., I get this error: `AttributeError: 'NoneType' object has no attribute 'currentanimation'`. I swear, I would have edited this stuff into 1 comment, but the system won't let me edit it even though it says I only posted the last one 4 minutes ago. – Aearnus Aug 30 '14 at 01:48
@CrazyM4n Yup, you need to define an `__init__` method. Currently, `Char` has no constructor, so it's returning nothing. http://stackoverflow.com/questions/625083/python-init-and-self-what-do-they-do – sgarza62 Aug 30 '14 at 01:51
I added that though, and put all the variable declarations in that (I did that before you suggested it). Still the same error. The full code is here: http://pastebin.com/APx4TeDn just in case you want to look. – Aearnus Aug 30 '14 at 01:53
