java - 当我装备盔甲时会激活的方法

我正在为Minecraft制作模组，现在我正在制作附魔，为您带来特殊的药水效果。我一直在进行Health Boost附魔，并从每次更新激活效果开始。执行此操作时，每次更新都会使凸轮效果受损，因此我切换到每次设备更改。这种方法效果更好，但是每次我多得到一个半心半意的人并更换/丢下一个物品时，它又成为了受伤的摄像头。我想使用某种onArmorEquip事件，但没有看到一个选项。我正在使用Minecraft 1.12.2 Eclipse，有人有建议吗？这是我的代码：

@SubscribeEvent
public static void enchantTankFunction(LivingEquipmentChangeEvent event)
{
    Object player = event.getEntityLiving();
    if(player instanceof EntityLivingBase)
    {
        EntityLivingBase entityPlayer = (EntityLivingBase)player;
        int levelFeet = EnchantmentHelper.getEnchantmentLevel(ENCHANT_TANK, entityPlayer.getItemStackFromSlot(EntityEquipmentSlot.FEET));
        int levelLegs = EnchantmentHelper.getEnchantmentLevel(ENCHANT_TANK, entityPlayer.getItemStackFromSlot(EntityEquipmentSlot.LEGS));
        int levelChest = EnchantmentHelper.getEnchantmentLevel(ENCHANT_TANK, entityPlayer.getItemStackFromSlot(EntityEquipmentSlot.CHEST));
        int levelHead = EnchantmentHelper.getEnchantmentLevel(ENCHANT_TANK, entityPlayer.getItemStackFromSlot(EntityEquipmentSlot.HEAD));
        if(!entityPlayer.getEntityWorld().isRemote && (levelFeet > 0 || levelLegs > 0 || levelChest > 0 || levelHead > 0))
        {
            entityPlayer.removePotionEffect(MobEffects.HEALTH_BOOST);
            entityPlayer.addPotionEffect(new PotionEffect(MobEffects.HEALTH_BOOST, (24 * 60 * 60 * 20), (levelFeet) + (levelLegs) + (levelChest) + (levelHead) - 1, false, false));
        }
        else
        {
            entityPlayer.removePotionEffect(MobEffects.HEALTH_BOOST);
        }
    }
}

最佳答案

这就是我要做的。您可以先更改哪个设备插槽，然后再更改该项目。这未经测试，但与此类似的东西应该起作用。

这会检查该实体是否是玩家，并且设备更改是在装甲插槽中进行的（您可能只需要此部分的帮助）。

@SubscribeEvent
public static void enchantSaturationFunction(LivingEquipmentChangeEvent event)
{
    if (event.getEntityLiving() instanceof EntityPlayer) // Remove this if you want other mobs to get the benefits
    {
        EntityEquipmentSlot slotChanged = event.getSlot();
        if (slotChanged.getSlotIndex() > 0 && slotChanged.getSlotIndex() < 5) // Check out the class EntityEquipmentSlot
        {

然后，要完成任务，将获得新装甲的ItemStack并检查结界。我从ItemStack::getTooltip偷了一些代码。

            ItemStack previousArmorPiece = event.getFrom();
            ItemStack newArmorPiece = event.getTo();

            NBTTagList nbtTagList = newArmorPiece.getEnchantmentTagList();

            for (int k1 = 0; k1 < nbtTagList.tagCount(); ++k1)
            {
                NBTTagCompound nbttagcompound = nbtTagList.getCompoundTagAt(k1);
                int enchantmentID = nbttagcompound.getShort("id");
                int enchantmentLevel = nbttagcompound.getShort("lvl");
                Enchantment enchantment = Enchantment.getEnchantmentByID(enchantmentID);
                if (enchantment instanceof MY_ENCHANTMENT)
                {
                    // They equipped armor with the necessary enchantment, so do what you want.
                }
            }

        }
    }
}
