自定義背包物品方法
這個也不光是指令方塊，可以在刷怪籠上運行，目的是可以放置壹個刷鉆石套裝僵屍的刷怪籠。這個是使用了1.8的新NBT：BlockEntityTag。指令例子：
/give @p minecraft:command_block 1 0
{BlockEntityTag:{Command:"/setblock ~ ~1 ~ minecraft:gold_block 0 replace"}}
註意：版本要最起碼14w07a。以上指令的意思就是給玩家壹個指令方塊。但是當玩家放置了這個指令方塊後，裏面就已經擁有自定義指令了，這條自定義指令就是：/setblock ~ ~1 ~ minecraft:gold_block 0 replace 。BlockEntityTag的意思就是把在玩家物品欄裏的物品自定義。之後不光是指令方塊，可以用在刷怪籠上面。指令例子：
/give @p minecraft:mob_spawner 1 0

這條指令會給玩家壹個普通的刷怪籠。但是玩家壹旦放下，就會發現這個刷怪籠裏的是鉆石套裝的無敵僵屍。於是玩家可以自己自定義方塊，然後給方塊自定義NBT，運用這個BlockEntityTag。
