self.rect not found?

Question

I have a program that is simply made to move an image around. I try to state the self.rect as part of a load_png() call, but it simply does not like it. THe reason I think this will work is from http://www.pygame.org/docs/tut/tom/games6.html, saying that this should work:

def __init__(self, side):
            pygame.sprite.Sprite.__init__(self)
            self.image, self.rect = load_png('bat.png')
            screen = pygame.display.get_surface()
            self.area = screen.get_rect()
            self.side = side
            self.speed = 10
            self.state = "still"
            self.reinit()

Here is my code, which according to the pygame tutorial from its own website, should work:

def _init_(self):
    pygame.sprite.Sprite._init_(self)
    self.state = 'still'
    self.image =  pygame.image.load('goodGuy.png')
    self.rect = self.image.get_rect()       
    screen = pygame.display.getSurface()

And it gives me this error:

Traceback (most recent call last):
File "C:\Python25\RPG.py", line 37, in <module>
screen.blit(screen, Guy.rect, Guy.rect)
AttributeError: 'goodGuy' object has no attribute 'rect'

If you guys need all of my code, comment blew and I will edit it.

Do you have a load_png function defined as per the link you provided? — timc, Dec 05 '12 at 03:36
AhHA! I assumed that was a built in python function. return image.get_rect() will suffice, correct? — Elias Benevedes, Dec 05 '12 at 03:38
You need to create an image using pygame.image.load and this will have a rect property. See my answer below. — timc, Dec 05 '12 at 03:39
The error you're getting is occurring outside of the code that you have posted. You will need to post that code as well. Also, why are you blitting the `screen` on itself? — kevintodisco, Dec 05 '12 at 03:55

You don't have a load_png function defined.

You need to create the pygame image object before you can access its rect property.

self.image = pygame.image.load(file)

Then you can assign the rect value using

self.rect = self.image.get_rect()

Or you could create the load_png function as per the example you linked.

You need to execute the function self.image.get_rect() - you need the parentheses. In your code you just have self.image.get_rect. – timc Dec 05 '12 at 03:47
Well firstly; the function should be __ init __ (note the double underscores). You only have single underscores (unless that is a typo). – timc Dec 05 '12 at 03:51
Thank you so much, I didn't know you needed double underscores. Thanks for putting up with this. – Elias Benevedes Dec 05 '12 at 03:54
No worries at all. If this has helped you it might be worthwhile accepting the answer to help others who may have a similar problem. – timc Dec 05 '12 at 03:55

There is no load_png function built-in to python or pygame. I imagine that the tutorial you are referring to defined it manually somewhere. What you want is pygame.image.load(filename) and then you can call get_rect() on the returned Surface object. The complete code would be as follows:

self.image = pygame.image.load('bat.png')
self.rect = self.image.get_rect()

Your second problem is that you've defined the function _init_, but you need double underscores: __init__.

Also, you need to post the code where the error is actually occurring.
