Python 从组中删除精灵
我正在用pygame做一个游戏，到目前为止，这个角色可以跳、跑、用剑和弓攻击，我可以在他两侧产卵蛇来追赶他。现在我希望玩家能够攻击一条蛇并让它死亡/消失。我制作了一个精灵（攻击区域），玩家在攻击的同时进行攻击。每一帧蛇都会检查它们是否与攻击区域发生碰撞。 该错误发生在检测到碰撞后，以及我想从列表中删除蛇时 这是一个错误的例子，发生在我生了两条蛇，其中一条与攻击区域相撞之后Python 从组中删除精灵,python,pygame,sprite,Python,Pygame,Sprite,我正在用pygame做一个游戏，到目前为止，这个角色可以跳、跑、用剑和弓攻击，我可以在他两侧产卵蛇来追赶他。现在我希望玩家能够攻击一条蛇并让它死亡/消失。我制作了一个精灵（攻击区域），玩家在攻击的同时进行攻击。每一帧蛇都会检查它们是否与攻击区域发生碰撞。 该错误发生在检测到碰撞后，以及我想从列表中删除蛇时 这是一个错误的例子，发生在我生了两条蛇，其中一条与攻击区域相撞之后 3.6.6 (v3.6.6:4cf1f54eb7, Jun 27 2018, 03:37:03) [MSC v.1900 6
