Question

我创建了这个代码，以便在敌人死亡时滚动项目：

    if len(current_enemy_group.sprites()) > 0:
        for goblin in current_enemy_group:
            if goblin.health <= 0:
                current_goblin_x = goblin.rect.x
                current_goblin_y = goblin.rect.y
                attack = False
                current_enemy_group.remove(goblin)
                all_sprites.remove(spell1)
                drop = random.randrange(0, 2, 1)
                if key_drop == False:
                    key_drop = True
                    key = Pickups(keyIMG, 35, 11)
                    current_pickups_group.add(key)
                    key.rect.x = current_goblin_x
                    key.rect.y = current_goblin_y
                    print("KEY DROPPED")

                elif drop == 1:
                    gold = Pickups(goldIMG, 24, 25)
                    current_pickups_group.add(gold)
                    gold.rect.x = current_goblin_x
                    gold.rect.y = current_goblin_y


                elif drop == 0:
                    print ("Item Drop")
                    ##WHAT TYPE OF ITEM
                    item_type = random.randrange(0, 3, 1)
                    if item_type == 0:
                        print("Potion Drop")
                        potion = Pickups(potionIMG, 9, 9)
                        current_pickups_group.add(potion)
                        potion.rect.x = current_goblin_x
                        potion.rect.y = current_goblin_y

                    elif item_type == 1:
                        print("Armor Drop")
                        if cloth_armor == False:
                            player.armor = 15
                            cloth_armor = True
                    elif item_type == 2:
                        print ("Weapon Drop")
                        item_rarity = random.randrange(0, 100, 1) + magic_find
                        if item_rarity >= 90:
                            print("ULTIMATE WEAPON AQCUIRED")
                            player.damage =1000000


                goblin.health = 2000

我添加了这个用于碰撞检测/物品拾取：

    item_pickup = pygame.sprite.spritecollide(player, current_pickups_group, False)
    if enemy_alive == True:
        print (gold.rect.x, potion.rect.x, key.rect.x)

    if item_pickup:
        for gold in item_pickup:
            player.gold += 1000
            print("You have acquired 1000 gold")
            current_pickups_group.remove(gold)
            current_pickups_group.update


        for potion in item_pickup:
            player.potion_count += 1
            print("+1 potions")
            current_pickups_group.remove(potion)
            current_pickups_group.update


        for key in item_pickup:
            have_key = True
            print("You now have the Gate Key")
            current_pickups_group.remove(key)
            current_pickups_group.update
            sound_KEYGRAB.play(loops=0, maxtime=0)

所以每次我的玩家精灵与current_pickups_group精灵碰撞时（当我走进项目来收集它时），它会在item_pickup中运行所有三个for循环。它按照这个顺序算作黄金，药水和钥匙。

我打印了黄金，药水和关键x坐标以查看它们的位置，当我收集东西时，它会将所有x坐标改变为我刚刚拾取的东西。

我无法弄清楚为什么会发生这种情况，我花了很多时间进行反复试验。

尽管黄金，药水和钥匙是不同的实例，但当我遍历item_pickup时，它们仍然被视为同样的事情。

如果有人能让我知道问题所在，我将不胜感激。

所以，我最终解决了这个问题。我将发布我的固定代码，以便如果其他人遇到此问题，那么他们可能会从中获得一些见解。

基本上，我将在下面显示，而不是将我作为单个项目传递的每个实例命名，而是将它们全部称为drop。我仍然需要一种方法来单独引用每个新实例，因为它们都被命名为drop right？所以我在Pickups类中添加了一个名为label的新参数，并在创建新实例aka item drop时传递了一个特定的标签。

    if len(current_enemy_group.sprites()) > 0:

        for goblin in current_enemy_group:

            if goblin.health <= 0:
                current_goblin_x = goblin.rect.x
                current_goblin_y = goblin.rect.y
                attack = False
                current_enemy_group.remove(goblin)
                all_sprites.remove(spell1)
                drop = random.randrange(0, 2, 1)
                if key_drop == False:
                    key_drop = True

                    drop = Pickups(keyIMG, 35, 11, "key")

                    current_pickups_group.add(drop)
                    drop.rect.x = current_goblin_x
                    drop.rect.y = current_goblin_y
                    print("KEY DROPPED")

                elif drop == 1:

                    drop = Pickups(goldIMG, 24, 25, "gold")

                    current_pickups_group.add(drop)
                    drop.rect.x = current_goblin_x
                    drop.rect.y = current_goblin_y


                elif drop == 0:
                    print ("Item Drop")
                    ##WHAT TYPE OF ITEM
                    item_type = random.randrange(0, 3, 1)
                    if item_type == 0:
                        print("Potion Drop")
                        drop = Pickups(potionIMG, 9, 9, "potion")

                        current_pickups_group.add(drop)
                        drop.rect.x = current_goblin_x
                        drop.rect.y = current_goblin_y

然后我修改了“on pickup”代码以引用标签为“x”的所有实例。

     item_pickup = pygame.sprite.spritecollide(player, current_pickups_group, False)

    if item_pickup:
        for drop in item_pickup:

            if drop.label == "gold":

                player.gold += 1000
                print("You have acquired 1000 gold")
                current_pickups_group.remove(drop)


            if drop.label == "potion":
                player.potion_count += 1
                print("+1 potions")
                current_pickups_group.remove(drop)

            if drop.label == "key":
                have_key = True
                print("You now have the Gate Key")
                current_pickups_group.remove(drop)
                sound_KEYGRAB.play(loops=0, maxtime=0)

所有项目在pygame RPG中相互碰撞而不是单一时被拾取
