Pygame编码敌人重生

Question

我正在尝试弄清楚如何在我的游戏中添加敌人重生，当敌人死亡时，它基本上是隐形的，你仍然可以射击它。我尝试了不同类型的代码并查看了不同的文章以寻求答案，但找不到任何东西。还需要帮助找到结束游戏的方法可能是在计时器上。感谢您的帮助，我真的很感激！

我查看了你的代码，但我找不到你删除地精对象的地方，这可能是敌人无敌的原因。我的建议是你为敌人列出一个清单。在您的情况下，您只有一个敌人，但这样做也可以让您拥有多个敌人。

goblins = [enemy(100, 410, 64, 64, 450)]

现在您还必须更改碰撞检测以使用goblins 列表而不是goblin 对象。

if goblins:
        for bullet in bullets:
            if bullet.y - bullet.radius < goblins[0].hitbox[1] + goblins[0].hitbox[3] and bullet.y + bullet.radius > goblins[0].hitbox[
                1]:
                if bullet.x + bullet.radius > goblins[0].hitbox[0] and bullet.x - bullet.radius < goblins[0].hitbox[0] + \
                        goblins[0].hitbox[2]:
                    hitSound.play()
                    goblins[0].hit()
                    score += 1
                    bullets.pop(bullets.index(bullet))

显然，您必须这样做以检测玩家和敌人以及您可能使用过地精的任何其他地方的碰撞检测。

现在我们在列表中有敌人，如果敌人死了，我们可以从列表中删除敌人。

if enemy.health < 1:
    goblins.remove(0)

然后只需将以下内容放在主循环中的某个位置，这样如果列表中没有敌人，它就会添加一个。

if not goblins:
    goblins.append(enemy(100, 410, 64, 64, 450))
