Pygame碰撞麻烦

Question

感谢这里的帮助，我在这个小程序上一直在取得进展。现在我收到以下错误消息："AttributeError: 'Sprite' object has no attribute 'draw'" 发生在碰撞事件之后，来自行："orchids.draw(screen)"。该程序在碰撞事件之前工作正常。我是 pygame 的新手，也是面向对象编程的新手。关于如何获取程序的任何想法运行?

Answer 1

你的循环

    for orchids in pygame.sprite.groupcollide(wasp_group, orchids, False, True):
        buzz.play()

导致名称 orchids 被一一分配给从 groupcollide() 返回的每株兰花。在 Python 中，for 循环不会引入新的作用域，因此发生的情况是您在该循环的每次迭代中覆盖名称 orchids。

然后，在 orchids.draw，您试图在单个兰花（Sprite 对象）中找到该方法，正如 Malik Brahimi 指出的那样，这是精灵组的一种方法。因此 'Sprite' object has no attribute 'draw'.

您可以通过将循环变量从 orchids 更改为 orchid 来解决此问题。然后什么都不会被覆盖。
