Question

这是我的第一篇文章。我需要为我的最终项目制作一个有效的游戏。基本上这个想法是让角色与一个物品精灵发生碰撞，并在屏幕上显示一个随机物品，告诉玩家物品是什么以及在哪里拍摄。

Answer 1

如果我明白你的意思，你就有很多Sprite种类型，你想随意选择一种。要做到这一点，只需将它们全部放在list中，使用random.choice选择一个，然后实例化它。像这样：

class OneKindOfParcel(Parcel): # etc.
class AnotherKindOfParcel(Parcel): # etc.
class AThirdKindOfParcel(Parcel): # etc.

parcels = [OneKindOfParcel, AnotherKindOfParcel, AThirdKindOfParcel]

# … later …

parceltype = random.choice(parcels)
parcel = parceltype()
allSprites.add(parcel)

你可能想给它一个位置，并显示一些关于它的名称和位置等等，但我想你知道如何做到这一点。

Answer 2

Quick and dirty是一个项目列表，然后使用random.choice模块中的random。

我如何制作一组精灵并随机选择一个？
