如题。1.8用指令可以搞到各种神附魔的装备，但是如何做到给你一把木剑，砍到生物后给它凋零效果呢？

我这个方法可能有bug……如果加上一个HurtTime应该会减小误差（然而我并不是太会）
/scoreboard objectives add use stat.useItem.minecraft:wooden_sword
/scoreboard objectives add select dummy
/scoreboard players set @a use 0
/scoreboard players set @a select 0
高频连/scoreboard players set @a select 1 {SelectedItem:{id:"minecraft:wooden_sword",Count:1b,tag:{display:{Name:"Wither"}}}}
/execute @a[score_use_min=1,score_select_min=1] ~ ~ ~ effect @a[rm=1] 20 1 1
给所有被木剑砍中的玩家1秒1级凋零效果
/give @p minecraft:wooden_sword 1 0 {display:{Name:"Wither"}}给玩家这把神奇的木剑

这很难 你可以用插件试试看

哇塞，新手表示看不懂

其实HurtTime很简单的。。。用超频加HurtTime把被打的实体设置成1即可

//创建变量
/scoreboard objectives add damage stat.damageDealt
/scoreboard objectives add select dummy
/scoreboard objectives add use stat.useItem.minecraft.wooden_sword @FHC红石 此处是点
/scoreboard objectives add behurt dummy
高频：
被打的生物给1分behurt
/scoreboard players set @e behurt 1 {HurtTime:9s}
/scoreboard players set @e behurt 0 {HurtTime:0s}
检测玩家拿着木剑
/scoreboard players set @a select 1 {SelectedItem:{id:"minecraft:wooden_sword",Count:1b,tag:{display:{Name:"Wither"}}}}
由于玩家手长是3，所以检测满足条件玩家范围内的实体，防止误判只检测离玩家最近并且受到伤害的实体
/execute @a[score_damage_min=1,score_select_min=1] ~ ~ ~ execute @e[r=3,c=1,type=!Player] ~ ~ ~ effect @e[r=3,c=1,type=!Player] minecraft:wither 5 0 true
最后设置玩家的值为0
/scoreboard players set @a damage 0
/scoreboard players set @a select 0
能不能不要评分不好回复
