[PyGame] platformer enemy animation

[Yegor123]

Im making a platformer and I wanted to make animated enemies ive been lookin up tutorials on how to do that and It doesnt work here is my code. the code here is just normal there isnt any animation added to the enemies yet

You should not be trying to add animation to your game. Try making one animated monster with no game play, no fancy background, nothing but the thing you are trying to learn. If you cannot get that to work, edit your code to a small sample (dozen lines or so) that doesn't require as many image files (2 or 3 max) and post that.

I would still like to ask how your game works, because so far I have only practiced in C#

Tips.
1. You do not want to load images in sprite class. This will load the image again making another copy in memory.
2. Convert your images. Otherwise pygame will do this every turn. If it needs too.

class ImageHandler:
    def __init__(self):
        self.lava = pygame.image.load(path_to_lava).convert()
        # etc

3. enumerate is your friend.

for row_count, row in enumerate(data):
    for col_count, tile in enumerate(row):
        # code

4. Rects has some nice short hand.

self.rect = image.get_rect(topleft=(x, y))
