Background:

So I am designing a wizard class that creates constructs. In order to make it multiplayer friendly, I am trying to make it so that the construct (which is usually some entity like an armor stand or zombie) has the UUID tag of the player in its data. I am aware that it is impossible for two entities to have the same UUIDs, so I am trying to take the player's UUIDs and add it into the tags of the construct.

The command I am using is:

/data modify entity @e[type=armor_stand,limit=1] Tags[0] set from entity @p UUIDLeast

/data modify entity @e[type=armor_stand,limit=1] Tags[1] set from entity @p UUIDMost

My end goal is to have it so that the armor stand has a tags that are a numbers equal to the UUIDLeast/UUIDMost of the player who summoned it.

Thank you for the help!

Tags is an array of strings which holds scoreboard tags. To achieve what you want, you need a custom tag. Now since you cannot add a custom tag to the entity directly, you have to use an item in the entities inventory or in this case, the armor/hand slots.

/summon armor_stand ~ ~ ~ {HandItems:[{id:"minecraft:apple",Count:1,tag:{uuidM:0d,uuidL:0d}}]}

now you can execute this command to store the numbers:

/data modify entity <armor_stand> HandItems[0].tag.uuidM set from entity @p UUIDMost

/data modify entity <armor_stand> HandItems[0].tag.uuidL set from entity @p UUIDLeast
