Rename items

[Starcage1]

Is there a way to dynamically rename an item?

For what - I want to have personal luggage for players. For example, a sophisticated backpack or any type of backpack mod, renamed to {name}'s luggage

So - Enter a name in the computer and then it renames the item in some way

No, afraid not. Renaming items normally requires XP, and computers can't store XP, and I'm not really sure how much I want to diverge from vanilla behaviour here. See #2184 for more discussion.

I see. Is there a way to do it using commands? (Through the command Computer)

Thanks for the help nonetheless!

Definitely command-able. I'm at work right now so could not tell you the exacts in code, but you can use /data get to grab information about the backpack, what's in it, its colours, etc. Then, it's simply a matter of /clear-ing the item from their inventory, and finally /give-ing them a new version with an updated name.

Maybe I am understanding it wrong, but won't clearing it would also clear the contents of the backpack? Don't wanna let players leave with an empty backpack lol. Also, can give command provide custom named items?

I would test myself, but I would like a little bit more info before I do anything. Thank you anyways!

Backpack data should be stored as either json, or as an ID. All you need to do is give it back with that data. Though I forgot that /data modify also exists.

There is no functions for renaming items as well as no API for working with anvil, perhaps for the reason mentioned above (you need XP for this).

However, there is mod called Advanced Peripherals (addon for CC). It gives possibility for the computers to work with other mods.

And there is mod Applied Energistics 2, which gives you powerful storage system and possibility to automate many things, such as item renaming.

So, not quite what you want, but you can use Inscriber Name Press from AE2.

For example:
Player inputs a luggage and the plate (with the player's name) => your program sends it to simple rename mechanism => on output player receives renamed luggage and plate.

Thanks for the idea!

However, it leads to the same problem. Players still need to do an extra step (putting the name in the plate using the cutting knife) before renaming, tho it's much more smoother than doing it in the anvil, say, in an airport or something

Still, it's a nice backup if I can't find anything better

Another idea I had in mind was, using a mod, to put an item (let's call it a tag) inside the bags and when looked at, shows a display of a number/name. This way, the tag can have unique number codes, like we do in real life, and the player with get their own to distinguish between them. No renaming of nothing and no input from players needed. I don't think there is a mod like that in forge 1.20.1 but it would be really cool

So, I look for a way to do it with command blocks. What I learned is that information on forums Q&A mostly outdated.

However with some in-game testing I found a possible solution (maybe not perfect one) without using other mods.

In this situation player gives his backpack. Then your program places a wooden sign and asks player to write the name on it. Then player confirms it in program and a command block reads this text and renames backpack. Then a turtle or another command block destroys the sign. And the player receives renamed backpack.

The command that works for me:
execute as @p run item modify block x y z container.0 {"function":"minecraft:set_name","target":"custom_name","entity":"this","name":{"block":"sx sy sz","nbt":"front_text.messages[0]","interpret":true,"italic":false}}

Here, x, y, z are the coordinates of the storage location where the backpack is at the renaming stage, and sx, sy, sz are the coordinates of the sign.

front_text.messages[0] is text from the first row of the sign.

Maybe this is for older versions, but in 1.20.1, minecraft uses data modify to do something like this. Also, placing a sign through commands hardcode it's nbt. Even if you write something on it, the data won't change. But no worries, I fixed it by cloning an existing sign

It works pretty good. Definitely the best solution yet that I have found and tested. Thanks for the help 🙏

(I still have 2-3 days before I get invested on my server so I am still gonna look for better ways, but this is my go to if I can't find any)

[canseesharp]

Oh, forgot to mention, I was testing on 1.21.8 version. 😅

If you want to dive deep in command blocks programming, I found this reddit post, it's about scoreboard. But you can read here about how to get player's name and it might help you in your case.

Also there is a util for generating code like the one I sent you. There are many different generators.

Hope this helps, good luck!

You can rename floppy disks with a computer via the label commands

Maybe you can place a floppy disk in the luggage to act as a name tag and maybe a unique id can be the data on the floppy disk
