Pygame Sprite Animation update

With this code you can animate this png files (go here to download them).

How to animate in different actions a sprite in pygame. It could seem a little tricky, but with the help of a class and the superclass Sprite and the Group class, we can manage the animation quite nicely with Python and Pygame, in this episode of the serie for the making of a platform game in Python…

Put the extracted images in a folder called “png” in the folder where this code is.

Right order of the images

As the images that ends with 10, 11, 12 ecc. would be positioned after image 1 and before image 2, I used this ‘trick’ to load the images from 1 to 9 first, then images 10 to… in a second list, so that they were displayed in the right sequence, with this code:

        im = glob.glob(f"png\\{action}*.png")
        lenim = len(im[0])
        self.images = [pygame.image.load(img) for img in glob.glob(f"png\\{action}*.png") if len(img) == lenim]
        self.images2 = [pygame.image.load(img) for img in glob.glob(f"png\\{action}*.png") if len(img) > lenim]
        self.images.extend(self.images2)

As you can see, I get the lenght of the first image (the one with the number 1) that is shorter than the ones with 10, 11… in the name. So I load these first and then the ones with the longer names. At the end I join them in one list of images with extend.

The whole code

A more efficient code… Use this one…

If you want to use the code to animate a sprite in a real game, you better use the following code:

Pygame Sprite Animation v.2 – Better coding? Test it checking FPS on the screen

This is the code

    frt = font.render(fr, 1, pygame.Color("coral"))
    return frt
