Pygame 2第一个投资组合游戏中发生冲突的问题

Question

我创建了这个帐户只是为了问这个问题：DI Am Learning Python，对于我的投资组合，我正在尝试在Python中创建一些游戏。

我对碰撞有问题，什至不知道如何检查错误在哪里。

当球员的子弹不在屏幕上时，它们会尽可能消失，并且最多有3个子弹的限制器。所以我想这部分肯定是好的。

但是，当子弹的矩形符合格林外星的矩形时，它不会消失也不会减少外星人的HP，因为外星人不会消失...

我已经很沮丧，因为这个虫子阻止了我2天...我有游戏 main

。

2 如果重要的话，我使用vsc，

Answer 1

为什么需要.x和.y属性？您有rect.x和rect.y。无论如何，当您更改x和y时，您还需要更改rect.x和rect.y 。注意，bullet.Rect.Colliderect（green_enemy.Rect）：使用green_enemy.Rect，但是green_enemy.x and code> green_enemy.yemy.yy.y 。 rect与X和y，rect.x和rect.y 当您更改X和y时，请勿神奇地更新。

在碰撞测试之前更新rect属性：

while run:
   # [...]

   for bullet in p_bulletList:
        bullet.y -= P_BULLET_SPEED
        if bullet.y <= 0:
            p_bulletList.remove(bullet)

        else:

            # update bullet.rect and green_enemy.rect
            bullet.rect.topleft = bullet.x, bullet.y
            green_enemy.rect.topleft = green_enemy.x, green_enemy.y

            if bullet.rect.colliderect(green_enemy.rect):
                green_enemy.hp -= 1
                p_bulletList.remove(bullet)
