Animated sprite from few images

Question

I've been searching for some good tutorial about making simple sprite animation from few images in Python using Pygame. I still haven't found what I'm looking for. My question is simple: how to make an animated sprite from few images (for an example: making few images of explosion with dimensions 20x20px to be as one but animated) Any good ideas?

Accepted Answer

You could try modifying your sprite so that it swaps out its image for a different one inside `update`. That way, when the sprite is rendered, it'll look animated.

Edit:

Here's a quick example I drew up:

```
import pygame
import sys

def load_image(name):
    image = pygame.image.load(name)
    return image

class TestSprite(pygame.sprite.Sprite):
    def __init__(self):
        super(TestSprite, self).__init__()
        self.images = []
        self.images.append(load_image('image1.png'))
        self.images.append(load_image('image2.png'))
        # assuming both images are 64x64 pixels

self.index = 0
        self.image = self.images[self.index]
        self.rect = pygame.Rect(5, 5, 64, 64)

def update(self):
        '''This method iterates through the elements inside self.images and 
        displays the next one each tick. For a slower animation, you may want to 
        consider using a timer of some sort so it updates slower.'''
        self.index += 1
        if self.index >= len(self.images):
            self.index = 0
        self.image = self.images[self.index]

def main():
    pygame.init()
    screen = pygame.display.set_mode((250, 250))

my_sprite = TestSprite()
    my_group = pygame.sprite.Group(my_sprite)

while True:
        event = pygame.event.poll()
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit(0)

# Calling the 'my_group.update' function calls the 'update' function of all 
        # its member sprites. Calling the 'my_group.draw' function uses the 'image'
        # and 'rect' attributes of its member sprites to draw the sprite.
        my_group.update()
        my_group.draw(screen)
        pygame.display.flip()

if __name__ == '__main__':
    main()
```

It assumes that you have two images called `image1.png` and `image2.png` inside the same folder the code is in.
