Changes to /replaceitem

I think it would be amazing if a new argument was added to /replaceitem: [replace | from]

Here's what I mean:

/replaceitem block <xyz> replace <slot> <item> (the current normal /replaceitem format just with the <replace> argument)

/replaceitem block <xyz> from [entity | block | storage]

NOTE: Read the comments, I address something there (I don't have room here).

After argument <entity> after argument <from>, you would identity/select the entity (only one entity can be selected)

After argument <block> after argument <from>, you would give the xyz coordinates

After argument <storage> after argument <from>, you would identity the storage

After you identify the block/entity/storage argument, you would provide the slot you are replacing from the block/entity/storage you're using, then the slot you are replacing

EXAMPLE:

/replaceitem entity @p from storage minecraft:example container.17 enderchest.0

This command would replace the enderchest.0 slot of the nearest player from the container.17 slot of the storage minecraft:example

If the storage minecraft:example does not have a container.17 slot, a error message would appear "The source storage does not have slot 17"

ANOTHER EXAMPLE:

/replaceitem block 0 0 0 from entity @e[type=armor_stand,limit=1,sort=nearest] armor.head container.48

If the block didn't have a container.48 slot, the error message would be "The target block does not have slot 48"

I hope you get the idea because I'm almost at the character limit. I'd love to see this implemented.

  I agree with what you say in this post, but you should remove the option to select items from storages, as they're just a storage of NBT data and they have no slots

  THIS IS THE NOTE FROM ABOVE! (Read the article if you don't have context)

  I know storages don't have slots, so one of two things can happen:

  You could simply remove the option (like in the post above) or

  You could add a new NBT tag specific to storages -- {StorageItems:[{}]}. The "format" would be the exact same as blocks and entities. This would act as the "slots" in storage. If this is not possible, then the first option is fine.

   

  mestesso123, thank you for the comment, I thought I addressed that in the article but apparently not.

  This is already possible with the /data modify command, but it takes three commands to work, possibly four. I'll take your second example for this one, note that storage is for NBT, not a container:

  First, you need to make sure that an item already exists in the area that you want to modify, and add a temporary item there if it doesn't:

  execute unless data block 0 0 0 Items[{Slot:0b}] run data merge block 0 0 0 {Items:[{Slot:0b, id:"minecraft:dirt",Count:1b}]}

  Then you have to change the tags id, Slot, and the tag compound with one command each:

  data modify block 0 0 0 Items[{Slot:0b}].id set from entity @e[type=armor_stand,limit=1,sort=nearest] ArmorItems[3].id
  data modify block 0 0 0 Items[{Slot:0b}].Count set from entity @e[type=armor_stand,limit=1,sort=nearest] ArmorItems[3].Count
  data modify block 0 0 0 Items[{Slot:0b}].tag set from entity @e[type=armor_stand,limit=1,sort=nearest] ArmorItems[3].tag

  And that's how to modify one slot at a time! Considering that we have functions in Minecraft Java Edition, there isn't a need for a shortcut for this.

  Update

  That's been added to Minecraft Java Edition, and the command has been moved to /item instead.
