玩家和生物的起始位置无法正常工作。当我在 SPRITES、Mob(即代码 atm 中的 #(中取出该行时，该位置与"新"中的地图阅读器一起使用。由于某种原因，ATM 玩家和暴徒的起始位置为 0， 0。我认为这与pos有关。
我尝试合并几个不同的教程，我走到了这一步，但现在我被困在起始位置并在键控时进行跳切。有什么想法吗？所有代码都在下面，在我的电脑上它们在不同的文件中。
愿你安好

设置。.PY：

如果我理解正确，您的问题就在这里：
self.pos = self.vel * self.game.dt + 0.5 * self.acc * self.game.dt ** 2
这基本上是说：
pos = vt + ½at²
您忘记了初始位置 pos0。它应该是
pos = pos + vt + ½at²
或者只是
pos += vt + ½at²
我发现了两个问题：
在Player类中，您必须设置矩形的中心。 默认情况下，新创建的矩形具有topeft坐标 (0， 0(。
class Player(pg.sprite.Sprite):
def __init__(self, game, x, y):
# ...
self.pos = vec(x, y) * TILESIZE
# Set the center of the rect to the self.pos vector.
self.rect = self.image.get_rect(center=self.pos)
在 Game 类中，您将创建两个Player实例。只需删除此行Player(self, col, row)即可。
def new(self): #start a new game, load map, place player
self.all_sprites = pg.sprite.Group()
self.walls = pg.sprite.Group()
self.mobs = pg.sprite.Group()
for row, tiles in enumerate(self.map.data):
for col, tile in enumerate(tiles):
if tile == '1':
Wall(self, col, row)
if tile == 'M':
Mob(self, col, row)
if tile == 'P':
# Here you create two player instances instead of one.
Player(self, col, row) # Delete this line.
self.player = Player(self, col, row)
Mob似乎在正确的位置生成。如果还有更多问题，请告诉我。
