/data command lets you manipulate nbt data however you want

[uneven terrace]

not with scoreboards tho

[vital spire]

i am not sure what do you mean exactly when saying "from scoreboard" can you elaborate on that

[uneven terrace]

just read the question

[vital spire]

i dont really understand still, lol can you explain

[outer otter]

maybeee they mean a dictionary

[vital spire]

how do you set nbt from scoreboard, what that means? just execute store?

[outer otter]

1 = sword
2 = stone

idk

[vital spire]

yeah, could be

[snow furnace]

you can use ```ansi
execute store result entity @n[type=minecart] path run scoreboard players get @s objective

[uneven terrace]

they just meant storing the score value inside nbt I think

[outer otter]

but

they cant

only markers have data for that

[vital spire]

huhhh?

[vital spire]

they can

with this

[outer otter]

yeah but not custom data

and idk where you would include your value

unless they store it in an item

[uneven terrace]

they can store like the count of an item

[vital spire]

why is the op not here

[uneven terrace]

or the data of the item

there are many usecases in which you want to modify the data of an item using scoreboards

[rocky leaf]

sorry i was afk

i meant that i have nbt ammo on item (ender_eye{ammo:30})

and i want to set this ammo to number from scoreboard (sorry for incorrect english)

[uneven terrace]

yea very easy using this command

[rocky leaf]

when i have score 60 = ammo:60

[uneven terrace]

you do need to modify the path to have the actual correct path

what version are you in?

[rocky leaf]

1.20.4

[uneven terrace]

ah ok

then your command should be:

[snow furnace]

execute store result entity @n[type=minecart] Items[0].nbt.ammo run scoreboard players get @s ammo

[rocky leaf]

@n?

[uneven terrace]

oh sorry a newfeature in 1.21

got so used to it

replace it with @e[type=minecart,sort=nearest,limit=1]

[uneven terrace]

ah yea use double

and then a 1 after that

for not scaling the score

[uneven terrace]

sorry sometimes my brain spits out crap, use byte

If you want to have more that 255 ammo, you can place int there instead

[rocky leaf]

ok, thanks

[uneven terrace]

using byte uses less data storage so it's more efficient for world lag and save file size
