我是使用pcb命令編輯器寫(xiě)的?這個(gè)軟件可以生成ooc（一鍵命令）可以到這個(gè)鏈接下載https://tieba.baidu.com/p/4309477852

為了使本系統(tǒng)適用于函數(shù)，沒(méi)有任何需要命令約制的連鎖命令方塊

原理：

給玩家新來(lái)玩家，為了能有歡迎系統(tǒng)，就要添加tag標(biāo)簽，一個(gè)計(jì)分板分?jǐn)?shù)，給完后給虛擬玩家計(jì)分板加1，如此反復(fù)，這樣每個(gè)玩家都能有不一樣的分?jǐn)?shù)

命令：

scoreboard objectives add UID dummy?

#新建計(jì)分板UID

scoreboard players add UID UID 0

#初始化虛擬玩家UID在UID計(jì)分板中的分?jǐn)?shù)

scoreboard objectives setdisplay list UID

#在點(diǎn)擊Tab玩家名字旁邊顯示計(jì)分板UID

scoreboard players add @a UID 0

#初始化玩家UID在UID計(jì)分板中的分?jǐn)?shù)

scoreboard players tag @r[score_UID=0,score_UID_min=0] add UID

#選擇@r[score_UID=0,score_UID_min=0]的玩家，給它添加UID的標(biāo)簽

scoreboard players operation @a[tag=UID] UID = UID UID

#選擇@a[tag=UID]將他的UID設(shè)為虛擬玩家UID

execute @a[tag=UID] ~ ~ ~ scoreboard players add UID UID 1

#給虛擬玩家分?jǐn)?shù)添加1（“execute?@a[tag=UID]?~ ~ ~??”≈命令約制只要有這樣的玩家才會(huì)執(zhí)行）

execute @a[tag=UID] ~ ~ ~ tellraw @a [{"text":"[UID 歡迎系統(tǒng)] ","color":"gold","bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false},{"text":"歡迎歡迎,歡迎新人：","color":"aqua","bold":true,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false},{"selector":"@a[tag=UID]","color":"red","bold":false,"italic":true,"underlined":true,"strikethrough":false,"obfuscated":false},{"text":"來(lái)到我們這，真的太好了?。?！","color":"aqua","bold":true,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false}]

#歡迎文本

scoreboard players tag @a[tag=UID] remove UID

#刪除標(biāo)簽UID

如果有哪個(gè)指令（例如scoreboard players tag，@r[score_UID=0,score_UID_min=0]）看不懂的，可以評(píng)論，我找時(shí)間寫(xiě)關(guān)于的一篇文章
