Pygame 碰撞无效 - pygame.sprite.collide_rect()

Question

我正在开发一款 space 射击游戏，在该游戏中，当 alien 精灵与 player 精灵碰撞时，我希望游戏结束。当编写碰撞代码时，它并没有结束游戏。有人可以帮助我吗？

        self.velY = random.randrange(2, 8)

有一个 config.py 文件，但我认为这个问题不需要它

Answer 1

您只测试与单个外星人的碰撞（这将是您创建并分配给 self.alien 的最后一个外星人）。您需要遍历所有外星人并测试玩家与他们每个人之间的碰撞。

def collision(self):
    # player collision with each alien
    for alien in self.allAliens:
        hits = pygame.sprite.collide_rect(alien, self.player)

        if hits:
            self.playing = False
            self.running = False
