为什么抛出这个错误？ （Python 3，Pygame）

Question

在我的游戏中，相关代码找到here，并且在本文末尾，在评估时会抛出此错误：

Traceback (most recent call last):
  File "C:\Users\Benjamin\Documents\GitHub\Tarbeyon\level.py", line 60, in <module>
    level.parseLevel() # Building the level
  File "C:\Users\Benjamin\Documents\GitHub\Tarbeyon\level.py", line 47, in parseLevel
    self.block[name] = Fountain((x, y), name)
  File "C:\Python33\lib\site-packages\pygame\sprite.py", line 124, in __init__
    self.add(*groups)
  File "C:\Python33\lib\site-packages\pygame\sprite.py", line 142, in add
    self.add(*group)
  File "C:\Python33\lib\site-packages\pygame\sprite.py", line 142, in add
    self.add(*group)
TypeError: add() argument after * must be a sequence, not int
[Finished in 2.8s]

我做错了什么？我可以为喷泉提供代码，这似乎是一个有问题的类。

喷泉类：

class Fountain(pygame.sprite.Sprite):
    def init(self, pos, name):
        # Call the parent class (Sprite) constructor
        pygame.sprite.Sprite.__init__(self)
        self.add(constant.blocks)
        self.add(constant.fountains)

        self.name = name

        self.particles = pygame.sprite.Group()
        self.image = pygame.image.load("Images" + os.sep + "blocks" + os.sep + "misc" + os.sep + "fountain1.png").convert()
        self.rect = self.image.get_rect()
        self.rect.x = pos[0]
        self.rect.y = pos[1]
        self.wImage = pygame.image.load("Images" + os.sep + "blocks" + os.sep + "misc" + os.sep + "fountain2.png").convert()
        self.wBoundingBox = self.wImage.get_rect()
        self.wBoundingBox.x = pos[0] + 25
        self.wBoundingBox.y = pos[1]

        self.waterOrigin = self.wBoundingBox.midbottom

        self.particles = {}
        create_particles()

    def create_particles(self):
        for i in range(10):
            self.particles[i] = WaterParticle(self.name, self.wBoundingBox, self.waterOrigin)

    def draw_particles(self, screen):
        for particle in self.particles:
            particle.draw(screen)

    def update(self):
        self.draw_particles()

Answer 1

通过调用初始函数init而不是__init__，Sprite类将使用((x, y), name)调用。

这可能会导致内部混淆 - 其中一个“真实”参数可能会在您的参数不匹配的上下文中使用。

Answer 2

您调用了方法“init”而不是“__init__”。
