PYGAME精灵不会在新的位置产卵

Question

好吧，所以游戏的目标是跑过包裹。这将显示包裹包含的物品以及从哪里取出物品。将包裹放到该位置后，我们的想法是为下一个包裹提供一个新的随机生成的项目和位置。我的问题是项目和位置似乎不会产生到一个新的位置，只是第一次滚动随机，并继续吐出相同的项目和位置。谁能帮助我？

这是我的代码

Answer 1

这是一些伪代码：

在播放器类的更新方法中执行以下操作：

if self.rect.colliderect(parcelLocation):
    parcelLocation.kill()

    newparcel = Parcel((random_x, random_y))
    newLocation = Location((random_x, random_y))

在Parcel和Location sprite类中为它们提供一个名为pos的参数，这样当它们获得(random_x, random_y)时，每次实例化一个新的

时，它们将被放在这个随机位置。

希望这有点帮助

祝你好运！ ：）
