Question

在与玩家角色发生碰撞时，我一直无法让我的通电消失。我已经能够通过子弹杀死敌人而获得通电，但我似乎无法收集它们。到目前为止，我已经列出了我的项目。我试过搞几个函数（pygame.sprite.spritecollide（）和pygame.rect.colliderect（）），但似乎都没有用。我似乎无法弄清楚问题是在我的播放器或Power类中，还是在＆＃34;同时＆＃34;循环在底部。

您没有在self.rect.x和self.rect.y的播放器上设置self.x和self.y，因此碰撞检测使用(0, 0)作为其位置

在pygame docs

中

spritecollide（sprite，group，dokill，collided = None） - ＆gt; Sprite_list

返回一个列表，其中包含与另一个Sprite相交的Group中的所有Sprite。通过比较每个Sprite的Sprite.rect属性来确定交集。
