記錄一下我的世界自定義裝備藥水BUFF的NBT代碼寫法，方便以后查詢，個人版本是JAVA1.19和1.20

先說結(jié)論：通過給裝備自定義Tags，然后循環(huán)命令方塊找到對應(yīng)tags循環(huán)effect給藥水效果即可，有一些小細(xì)節(jié)需要注意

首先貼一下各種藥水對應(yīng)的英文：

這里普通的裝備屬性和附魔nbt就不再贅述，就比如改變裝備的附魔屬性，改變裝備的最大生命值還有盔甲值等，本文只涉及裝備的藥水效果。

首先是裝備的定義，nbt代碼如下：

{Count:1,

id:"minecraft:stick",

tag:{

Damage:0,

Enchantments:[{id:"minecraft:knockback",lvl:5}],

display:{

Name:"{\"text\":\"無敵木棍\",\"color\":\"dark_red\",\"italic\":false,\"bold\":true}",

Lore:["{\"text\":\"在主手時獲得抗性提升V\",\"italic\":false,\"bold\":false,\"color\":\"red\"}"],

},

Tags:["test"]

}

}

定義了一根木棍，名字和Lore修飾可以隨便改，帶擊退附魔，這里獲得藥水BUFF的關(guān)鍵在于

Tags:["test"]，用于標(biāo)簽綁定，盔甲等同理，必須是獨(dú)一無二的tags用于綁定。

接下來放置一個循環(huán)命令方塊，如果是主手持道具，參考代碼如下：

/effect give @a[nbt={SelectedItem:{tag:{Tags:["test"]}}}] minecraft:resistance 2 4

自行替換藥水效果即可，當(dāng)?shù)谰咴谥魇謺r就會生效

如果是穿在身上才生效的裝備，裝備示例如下：

{

Count:1b,id:"minecraft:diamond_helmet",

tag:{

Damage:0,Unbreakable:true,

Enchantments:[{id:"minecraft:protection",lvl:10}],

display:{

Lore:["{\"text\":\"限定頭盔\",\"italic\":false,\"bold\":false,\"color\":\"gold\"}",

"{\"text\":\"穿上獲得力量提升X\",\"italic\":false,\"bold\":false,\"color\":\"dark_purple\"}"],

Name:"{\"text\":\"定制頭盔\",\"italic\":false,\"color\":\"light_purple\",\"bold\":true}"},

Tags:["Rhead"],

AttributeModifiers:[{Operation:0,Amount:12,UUID:[I;1,251,3,4],Slot:head,AttributeName:"generic.armor"},

{Operation:0,Amount:5,UUID:[I;2,2,3127,4],Slot:head,AttributeName:"generic.armor_toughness"},

{Operation:0,Amount:0.5,UUID:[I;1111,251,3,4],Slot:head,AttributeName:"generic.knockback_resistance"},

{Operation:0,Amount:20,UUID:[I;3,2,3128,4],Slot:head,AttributeName:"generic.max_health"}]

}

}

命令方塊參考代碼如下：

/effect give @a[nbt={Inventory:[{Slot:103b,id:"minecraft:diamond_helmet",tag:{Tags:["Rhead"]}},],}] minecraft:strength 3 9

以下是其他部位的裝備參考：

/effect give @a[nbt={Inventory:[{Slot:102b,id:"minecraft:diamond_chestplate",tag:{Tags:["Rchest"]}},],}] minecraft:resistance 3 2

/effect give @a[nbt={Inventory:[{Slot:101b,id:"minecraft:diamond_leggings",tag:{Tags:["Rlegs"]}},],}] minecraft:absorption 3 9

/effect give @a[nbt={Inventory:[{Slot:100b,id:"minecraft:diamond_boots",tag:{Tags:["Rfeet"]}},],}] minecraft:regeneration 3 4

其中Slot對應(yīng)裝備位置，不能錯誤，103對應(yīng)頭部，102對應(yīng)胸部等等，id需要改成裝備的英文，然后更改Tags為自定義裝備的Tags即可，后面的藥水效果等級和持續(xù)時間自己替換。
