Hi! I am creating a game using pygame. Please do note that I am new to game development and programming.

I'm using Tiled to create a tile map for my game. However, this error occurs when I try to run my program with pygame:
Traceback (most recent call last):
File "C:\Users\Rose\Desktop\mp2 sh*ts\sh*", line 114, in <module>
File "C:\Users\Rose\Desktop\mp2 sh*ts\sh*", line 58, in main
self.tilemap = tmx.load('tileMap.tmx', screen.get_size())
File "C:\Users\Rose\Desktop\mp2 sh*ts\", line 835, in load
return TileMap.load(filename, viewport)
File "C:\Users\Rose\Desktop\mp2 sh*ts\", line 714, in load
layer = Layer.fromxml(tag, tilemap)
File "C:\Users\Rose\Desktop\mp2 sh*ts\", line 255, in fromxml
data = data.decode('base64').decode('zlib')
File "C:\Python27\lib\encodings\", line 42, in base64_decode
output = base64.decodestring(input)
File "C:\Python27\lib\", line 325, in decodestring
return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

My code looks like this:

import pygame
import tmx

class Player(pygame.sprite.Sprite):
def __init__(self, location, *groups):
    super(Player, self).__init__(*groups)
    self.image = pygame.image.load('red.gif').convert()
    self.rect = pygame.rect.Rect(location, self.image.get_size())
    self.resting = False 
    self.dy = 0 

def update(self, dt, game):
    last = self.rect.copy()

    key = pygame.key.get_pressed()
    if key[pygame.K_LEFT]:
        self.rect.x -= 150 * dt
    if key[pygame.K_RIGHT]:
        self.rect.x += 150 * dt

    if self.resting and key[pygame.K_SPACE]:
        self.dy = -500
    self.dy = min(400, self.dy + 40)

    self.rect.y += self.dy * dt

    new = self.rect
    self.resting = False
    for cell in game.tilemap.layers['triggers'].collide(new, 'blockers'):
        if last.right <= cell.left and new.right > cell.left:
            new.right = cell.left
        if last.left >= cell.right and new.left < cell.right:
            new.left = cell.right
        if last.bottom <= and new.bottom >
            self.resting = True
            new.bottom =
            self.dy = 0
        if >= cell.bottom and < cell.bottom:
   = cell.bottom
            self.dy = 0

    game.tilemap.set_focus(new.x, new.y)

class Game(object):
def main(self, screen):
    clock = pygame.time.Clock()

    background = pygame.image.load('bg.png')

    self.tilemap = tmx.load('tileMap.tmx', screen.get_size())

    self.sprites = tmx.SpriteLayer()
    start_cell = self.tilemap.layers['triggers'].find('player')[0]
    self.player = Player((start_cell.px,, self.sprites)

    fps = 30
    running = True
    while running:
        dt = clock.tick(fps)

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
            if event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
                running = False

        self.tilemap.update(dt/1000., self)
        pygame.display.set_caption("Little Red")
        screen.blit(background, (0,0))

if __name__ == '__main__':
    width = 1024
    height = 480
    screen = pygame.display.set_mode((width, height))

Here is the link to the file I used.

This youtube video served as my guide.

Lastly, this is how my map looks like.

Thank you in advance to those who would answer this question!

I have tried searching for possible ways to troubleshoot this error, but I'm yet to find a concrete solution.
