Pygame menus

[rhys_2]

Hi, i have been making a maze game in pygame. I have made every level and have them all in different folders so i can find them easily. I have been trying to make a menu for the game where you are able to pick any level and play it. i have tried and failed many time in trying this where when you click to play level 1 it open up the folder and that level. if anyone can help it would be amazing

import os
import pygame
import random

pygame.init()

Colours im using in the game

white = (255,255,255)
black = (0,0,0)
red = (255,0,0)

FPS = 60

The dimension of the game

display_width = 680
display_height = 440

Class for the player

class Player(object):

def __init__(self):
    self.rect = pygame.Rect(40, 40, 30, 30)

def move(self, dx, dy):
    #Move each axis separately. Note that this checks for collisions both times.
    if dx != 0:
        self.move_single_axis(dx, 0)
    if dy != 0:
        self.move_single_axis(0, dy)

def move_single_axis(self, dx, dy):
    #Move the player
    self.rect.x += dx
    self.rect.y += dy

    #If you collide with a wall, move out based on velocity
    for wall in walls:
        if self.rect.colliderect(wall.rect):
            if dx > 0: #Moving right, Hit the left side of the wall
                self.rect.right = wall.rect.left
            if dx < 0: #Moving left, Hit the right side of the wall
                self.rect.left = wall.rect.right
            if dy > 0: #Moving down, Hit the top side of the wall
                self.rect.bottom = wall.rect.top
            if dy < 0: #Moving up, Hit the bottom side of the wall
                self.rect.top = wall.rect.bottom

Class to hold a wall rect

class Wall(object):

def __init__(self, pos):

    walls.append(self)

    self.rect = pygame.Rect(pos[0], pos[1], 40, 40)

Initialise pygame
