子弹不与敌人的Pygame相撞（Python 3）

Question

我想制作一个类似的大型游戏，你跳来跳去拍摄东西。但是我发现碰撞有问题，我有一个视频：

https://youtu.be/p2VCtbBkefo

我打算让这个项目成为开源的，所以任何人都可以自定义它。请不要窃取此代码，但您可以使用它来帮助您解决问题。因为我还没有公开把它放在GitHub上。

loadLevel方法的这一部分会导致问题：

for amount in range(0, enemies):
    group2.add(FlyingEnemy(self))
    group3.add(FlyingEnemy(self))
    self.enemies.add(FlyingEnemy(self))
    self.enemiesList.append(FlyingEnemy(self))

您要向这些组添加4个不同的FlyingEnemy对象和列表（顺便说一下，列表没用），因此self.all_sprites组和self.enemies组中的精灵不一样。

由于您只更新了all_sprites而不是enemies，因此enemies组中用于碰撞检测的精灵会保留在左侧屏幕边缘时间也是看不见的，因为你不画这个组。

要解决此问题，请创建一个实例并将此实例添加到两个组：

for amount in range(0, enemies):
    enemy = FlyingEnemy(self)
    self.enemies.add(enemy)
    self.all_sprites.add(enemy)

我通过在self.enemies组中打印一个敌方精灵的矩形来发现错误。然后我检查了这个精灵的update方法，但它看起来是正确的，所以我去了loadLevel的实例化部分并注意到了错误。
