当我运行代码时，blob（敌人）不会产生，但是当我在敌人身上取出敌人时，这被认为是碰撞，blob会产生并跟随。我已经尝试了许多碰撞的东西，但这是我第一次在pygame中创建游戏，所以我必须查看所有内容。
答案 0 :(得分：0)
我猜你的问题是，有时你的敌人会直接在玩家旁边产生，所以会立即发生碰撞。我不知道你使用的图像是什么样的，但要确保它们不是太大，空间很大，因为你的碰撞不是像素完美，而是使用图像的整个尺寸/矩形。 / p>
否则，您的代码到目前为止应该可以正常工作，但您仍然可以稍微改进一下。例如，由于您已经为Sprite使用了character类，因此您还可以使用Group类使代码更简单（绘制/移动/碰撞检测）。
以下是它的样子：

请注意主循环只需要调用all_sprites.update和all_sprites.draw，其余部分由类Enemy和Character本身处理。
