Question

我正在为我在课堂上的最后一个项目制作游戏。我对pygame和整个游戏开发的事情都很新。我用这个video作为我的向导。

我使用Tiled为我的游戏制作了一张瓷砖地图，但是当我尝试用pygame运行它时，我得到了这个：

Traceback (most recent call last):
File "C:\Users\Rose\Desktop\mp2 shits\shit.py", line 114, in <module>
Game().main(screen)
File "C:\Users\Rose\Desktop\mp2 shits\shit.py", line 58, in main
self.tilemap = tmx.load('tileMap.tmx', screen.get_size())
File "C:\Users\Rose\Desktop\mp2 shits\tmx.py", line 835, in load
return TileMap.load(filename, viewport)
File "C:\Users\Rose\Desktop\mp2 shits\tmx.py", line 714, in load
layer = Layer.fromxml(tag, tilemap)
File "C:\Users\Rose\Desktop\mp2 shits\tmx.py", line 255, in fromxml
data = data.decode('base64').decode('zlib')
File "C:\Python27\lib\encodings\base64_codec.py", line 42, in base64_decode
output = base64.decodestring(input)
File "C:\Python27\lib\base64.py", line 325, in decodestring
return binascii.a2b_base64(s)
binascii.Error: Incorrect padding
[Finished in 5.0s]

这是我的代码：

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 <= cell.top and new.bottom > cell.top:
            self.resting = True
            new.bottom = cell.top
            self.dy = 0
        if last.top >= cell.bottom and new.top < cell.bottom:
            new.top = 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, start_cell.py), self.sprites)
    self.tilemap.layers.append(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))
        self.tilemap.draw(screen)
        pygame.display.flip()

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

提前感谢那些善意帮助的人！

编辑：这就是我的地图看起来像...... tmx file

Answer 1

看起来tmx.py无条件地尝试对数据进行base64-decode和zlib-decode，而不检查数据的实际格式。最近版本的Tiled默认为CSV格式的数据，因此请务必更改在Tiled中的Map Properties中将tile图层数据格式转换为base64 + zlib。

创建新地图时，您只需要设置一次，因为Tiled会记住您的偏好。

解决pygame binascii.Error：填充不正确？
