I’m a newbie in Python and Pygame and I’ve an issue with my sport in pygame. I’ve Maze class and Player class however I am unable to do correct collisions. I reached the second the place I do not know why my code is not working.

Here is my code:

class Maze(pygame.sprite.Sprite):
def __init__(self):
    self.W = 25
    self.H = 14
    self.maze = [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
                 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1,
                 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 0, 1, 0, 1,
                 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 0, 1,
                 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 1, 0, 1,
                 1, 0, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 1, 1, 0, 1, 0, 1,

Can somebody clarify to me why it is not working and assist to enhance it?

I attempted many concepts – even writing from hand positions x and y to create collisions. But it is actually dangerous follow to take action I turned to pygame possibility sprite.colliderect(sprite2)

I need to obtain data why my code is not working correctly and suggestions for bettering it.
