With this code you can animate this png files (go here to download them<\/a>).<\/p>\n\n\n\n

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

Put the extracted images<\/strong> in a folder called “png”<\/strong> in the folder where this code is.<\/p>\n\n\n\n

Right order of the images<\/h2>\n\n\n\n

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:<\/p>\n\n\n\n

        im = glob.glob(f\"png\\\\{action}*.png\")\n        lenim = len(im[0])\n        self.images = [pygame.image.load(img) for img in glob.glob(f\"png\\\\{action}*.png\") if len(img) == lenim]\n        self.images2 = [pygame.image.load(img) for img in glob.glob(f\"png\\\\{action}*.png\") if len(img) > lenim]\n        self.images.extend(self.images2)<\/pre>\n\n\n\n
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<\/strong>.<\/p>\n\n\n\n
The whole code<\/h2>\n\n\n\n
