我正在开发pygame中的游戏。我有一个角色精灵和一个都是图像的地面。我想使用遮罩检测这些对象之间的碰撞。这是我的代码：

它仍然非常混乱，因为我才刚开始，所以我遗漏了一些不必要的内容，以使其更加清晰易读。当我尝试在redraw_game_window（）函数中检测到冲突时，出现以下错误消息：
追踪（最近通话）： 文件“ c：/ Users / Pc / Desktop / Python / Games / Game Engine / First Game.py”，第234行 redraw_game_window（） 文件“ c：/ Users / Pc / Desktop / Python / Games / Game Engine / First Game.py”，行215，在redraw_game_window中 如果pygame.sprite.spritecollide（头像，地面，False，pygame.sprite.collide_mask）： spritecollide中的文件“ C：\ Users \ Pc \ AppData \ Roaming \ Python \ Python37 \ site-packages \ pygame \ sprite.py”，第1532行 返回[如果碰撞，则表示组中s的s（sprite，s）]TypeError：“地面”对象不可迭代
我尝试过的：
有人知道我在做什么错吗？
代码在非PyGame精灵上的对象上使用PyGame精灵库spritecollide（）函数。如果要创建自己的精灵，应该添加并维护Rect对象，以使代码使用Rect.collide组函数。
但是将现有的类似Sprite的对象转换为正式的PyGame Sprite会更加容易和快捷。这意味着继承基Sprite类，并重写某些函数和成员变量。 使用Sprite类是（IMHO）最简单，最好的方法。

为了简洁起见，我没有转换跳转功能。您还需要对Platform进行类似的更改。
