你好，我试图随机产生我的Pipes类的副本，然后将它们显示到屏幕上。我设置了一个随机数生成器，有1/3的机会得到1，如果它得到1，我让另一个随机数生成器选择一个0到600之间的数字（我的屏幕宽度）作为x坐标新的精灵。然后使用随机x坐标和预定义的y坐标将该精灵显示到屏幕上。Pygame如何创建Sprite类的重复项然后将它们放入组中？
class Pipes(pygame.sprite.Sprite):
def __init__(self, x):
pygame.sprite.Sprite.__init__(self)
self.img = pygame.image.load('C:\\Users\\Ben\\Documents\\sprite.png').convert()
self.imx = 0
self.imgy = 375
self.setDisplay = pygame.display.get_surface()
def playerRect(self):
self.x = self.imgx
self.y = self.imgy
self.rect = pygame.draw.rect(setDisplay, pygame.Color(0, 0, 255), pygame.Rect(self.x, self.y, 32, 32))
def draw(self):
self.setDisplay.blit(self.img)
def update(self):
self.spawn = random.randint(0, 3)
if self.spawn == 1:
self.spawnx = random.randint(0, 600)
setDisplay.blit(self.img, [self.spawnx, 375])
allPipes.add(new_instance(self.spawnx))
然后我制作了一组叫做allPipes的小精灵，它们将容纳Pipe的新实例并为Pipe构造一个构造函数。
allPipes = pygame.sprite.Group()
pipe = Pipes(0)
然后在我的gameloop我叫管道画出函数随机派生的新实例，并绘制和更新allPipes组，但对于精灵的图像出现在屏幕上，但随后当新的出现，这使得dissapear我相信它实际上并不是每次都会制作一个新的Pipes实例。可以somone请帮忙吗？

请确认您的代码的缩进是正确的，并删除在代码中所有前导空格，以使其更具可读性。如果这里的代码和你的代码完全一样，那么看看下面的代码：'for sprite in allPipes：'之后的行不在循环中执行，因为它没有缩进。 – Mailerdaimon
在Pipes的更新方法中添加'new_instance（self.spanx）'，但我不认为你实际上在任何地方定义了new_instance –
