Assigning A Tag To An Item Based On It's NBT

[unique silo]

As the title suggests, is there a way to assign an item tag (i.e. forge:cobblestone) to an item with specific NBT data (i.e. if "stone" is present in it's NBT).

Script below is an attempt I made, led to a crash lol lmfao

ServerEvents.tags('item', event => {
      event.add('medievalorigins:is_golden_weapon', Item.of("tetra:modular_sword", '{display:"/^Gold*/"}'))
})

wanting to add a tag each base color of leather chestplate and can't work out how to include the nbt in the list, stuck here:
event.add('modpack:primary_leather_chestplate_colours', ['minecraft:leather_chestplate'])

I'll give it a look thanks :D

[unique silo]

a h

so I'll take that as a No I Can't Do That

[viscid tapir]

I don't think so?

You are on a different version

[unique silo]

1.20.1 Forge

[viscid tapir]

But I can't recall... seeing this proven otherwise

[unique silo]

yeah I was gonna try some jank to read the display name instead of the NBT (i.e. Is a Sword with display keyword "Gold") but im lost at that

[unique silo]

cheers for the quick help tho :D

[viscid tapir]

Yeah I'm logging onto Minecraft right now to see if I can find something that proves this otherwise

[unique silo]

I'll leave this open for now then 👍

[clever cape]

Why do you need the tag?

[unique silo]

ok so
there's this origin, Goblin, gets a buff on gold tools and such, the buff is applied to items with the tag
I wanna expand what the tag applies to, including Tetra tools, hence NBT shenanigans

[clever cape]

Ok. Why not (temporarily) apply an effect or tweak a player attribute when an item with the tag is held?

That's what the origin does right? If you can't directly integrate the item into the origin handler then why not make a parallel system?

[unique silo]

if you can DM me the docs on this that'd be sick

[clever cape]

Is it this one, by the way? https://www.curseforge.com/minecraft/mc-mods/medieval-origins-revival

[unique silo]

yeye

[clever cape]

Gotcha. Let me check the source then

[unique silo]

I have a very cursary knowledge on origins and datapacks, but I did unpack it to get that tag info

[clever cape]

https://github.com/muon-rw/Medieval-Origins-Revival/blob/1.20.1-multiloader/common/src/main/resources/data/medievalorigins/powers/goblin/durability.json

You're talking about this power, right?

[viscid tapir]

[unique silo]

no I'm looking at Greedy which isn't there for some reason

[clever cape]

I noticed that as well. It's listed in the goblin origin json, at least

[viscid tapir]

So I don't think item tags on things based on NBT is possible because I couldn't find a single item in the vanilla game that demonstrates this working and then I tried thinking of a single mod where this situation exists and it ends up being a different item.

[unique silo]

yeye fair, so I gotta look for an origins forward solution over a tag solution it'd seem

[viscid tapir]

What?

Oh lemme read up I guess

[unique silo]

(tl;dr the tag is for origins compat, so I'll work that way in)

[viscid tapir]

Okay you can also use KubeJS for testing what item they're holding and applying a effect

However if you want to use origins then you're free to do so

[clever cape]

I mean, you could do some nbt transfer shenanigans and swap tetra:modular_sword for kubejs:gold_sword and then somehow integrate your KJS item back into tetra, but all that seems like it's almost more trouble than it's worth

[unique silo]

will likely have to

[viscid tapir]

I just haven't heard from my friend, who likes the mod, good things about the json files. To be fair, he was comparing it to kubejs.

[clever cape]

Is there no way to check for the nbt of an item in origins?

[clever cape]

That's somewhat of a high bar lol

[unique silo]

absolutely no idea lol, hence me working with kubeJS

[unique silo]

sounds fun lol

[viscid tapir]

They work in Json files. Again, from what I've heard. They can't do much outside of what the mod already allows because when you step off that foundation there's zero log.

No probejs

[unique silo]

I don't use probeJS anyway, I prefer my suffering raw

Pause.

[unique silo]

anyway if that's that I'll do a little tl;dr and close the ticket
cheers for the help 👍

[viscid tapir]

Wait

[unique silo]

waiting

[viscid tapir]

Oh wow that worked

So

Basically are you closing the ticket, then reopening the one about this "Testing for item in hand to apply affect" or are you using origins?

[unique silo]

using origins, I'll need to test for origin anyway now so it'd be best if I work that way

[viscid tapir]

All right, see ya, and good luck

[unique silo]

tl;dr You can't
see reply for details 👍
