Detect in what way?

Do you want to store the UUID somewhere? Compare it to another UUID?

[blazing sable]

compare uuids

[blazing sable]

i got were to store the uuids

but idk how to compare them

[timid thunder]

How did you store them?

[blazing sable]

in a marker name

its for a projectile

[timid thunder]

Don't believe there's really a good way to compare strings like that

You'll want to instead store the UUIDs as scores (you can either do each of the four UUID numbers as a separate score for maximum accuracy, or just one of them, up to you). Then you can compare them with execute if score

[blazing sable]

is there a way to do what i asked

it doesnt need to be complicated

like

what is the data path to a uuid

and how do i detect its number

[timid thunder]

Yes, the way I described

[timid thunder]

You detect it in the same way you stored it. What you actually want to know is how to compare it. And the way is by storing it to a score

[blazing sable]

so scorebored?

[timid thunder]

Yes

[blazing sable]

it just outputs it to 4

[timid thunder]

You can't target the entire UUID NBT because it's a list, it'll just output the number of entries in it. You need to do UUID[0] for just the first number, UUID[1] for the second, etc

[carmine mirage]

if you really wanted to streamline it as much as possible you could probably take a function macro that takes target selectors as inputs

[blazing sable]

i am using macros

for this

[carmine mirage]

but generally when i need to do this i just compare 4 scores for each uuid number separately in 4 ifs

[blazing sable]

is there a way to check for if i uuid is a specific number via data?

[carmine mirage]

generally i would suggest foregoing macros and storing the uuids of entities you will be comparing with 4 scoreboards

[carmine mirage]

yeah you can store it as score and then set a fake player to the value you want to check it (or use another entity/player’s value) for an if score = score statement

basically you can only compare scores but you can turn the data into a score

[blazing sable]

without scores and using macros

[carmine mirage]

no

i mean

technically you could maybe see whether merging succeeds? but no 2 entities should have the same uuid to begin with

[blazing sable]

i know

[blazing sable]

i need it for a projectile

essentially

i stored the uuid into a marker's name

and i was wondering if there is a way to compare that

[carmine mirage]

i would strongly suggest using an incremental id system for that type of thing, simpler and less laggy to work with

but if you really wanna use uuid without scores or macros, yeah you might be able to see whether data modify merge can be used to determine that

[blazing sable]

let me refrace it, is there a way to detect what uuid a entity has via execute if or selectors?

[carmine mirage]

not without using scoreboards and/or macros

well scoreboards are really the simplest way though

[blazing sable]

i just dont want my lines to be long asf

and its for a damage command

so the only way for the cause to be the original entity

is via macros

[blazing sable]

.

[timid thunder]

Or an enchantment

[final crater]

often, that's difficult if you want at least some complexity in your datapack.

you could use the wraparound feature in most code editors if only the scrolling is annoying you.

[blazing sable]

for my use case

using macros is my only option i think

[final crater]

or split the line into multiples with \ at the end

[final crater]

you can use a predicate to check the scores

this reduces the line size considerably

[blazing sable]

i want to use it for the damage command

so essentially

[final crater]

and?

[blazing sable]

i want another entity to execute the command

becouse that will be the easiest way to do so

there is no way to compare if the entity is @s or @e i beleave

[final crater]

what?

what do you meany by that?
What does comparing @s and @e mean?

[obsidian wave]

you dont need to use a macro for that. just apply a temporary tag to the original entity which you can reference in the damage command

[blazing sable]

i know

[blazing sable]

but if two people use it at ones

[final crater]

not possible

even if they run it in the same tick, everything gets executed sequentially, not parallel.

[blazing sable]

its not instant

[final crater]

ah, that's what you mean

[blazing sable]

i need an original entity

[final crater]

what exactly are you trying to create?

[blazing sable]

gyro's steel balls from sbr

[final crater]

sbr?

[obsidian wave]

jojos bizzare adventure part

[blazing sable]

7

[obsidian wave]

you apply the tag during the damage function and remove it during the damage function. the easiest way is gonna be with scoreboards as said before

[blazing sable]

cant you check for uuid with execute if data?

[final crater]

only with macros, as you have to check for the exact nbt

[blazing sable]

i know

im using macros

but what exactly is the path/way

[final crater]

UUID

[blazing sable]

i know

but like UUID:?

UUID.?

[final crater]

there is no previous tag thta's it nested in

there also is no sub path

UUID is an array of 4 integer values

[blazing sable]

is there a way to check for the values inside?

[final crater]

UUID[0] <- first integer
UUID[1] <- second integer
UUID[2] <- ...
UUID[4] <- ...

[blazing sable]

i know

but like

how do i check the string inside

[final crater]

there is no string inside

only those 4 integers

[blazing sable]

alr

[final crater]

The I; at the beginning is just and indicator to show you what type of array that is.

[blazing sable]

is there a way to store the name of the player?

[final crater]

1. create a loot table that drops a player head and apply the fill_player_head function.
2. drop loot table (spawn or insert into an inventory)
3. read the name nbt inside the profile tag

[blazing sable]

any way to compare them?

[final crater]

store the first name in a storage and overwrite it with the second name. if the overwrite command returns 0, nothing changed and it's the same name. If it returns 1, the data changed and that means they are different names.

[blazing sable]

can you show in a function?

[cursive bison]

data modify storage namespace:compare name set from entity @n[type=minecraft:item, tag=head] profile.name
execute store success score #success temp run data modify storage namespace:compare name set from entity @n[type=minecraft:item, tag=other_head] profile.name

execute if score #success temp matches 0 run say Same name
execute if score #success temp matches 1 run say Different names

[final crater]

profile.name is not the correct path. Depending on if you get it from an item on the ground or from an inventory, you have to use Item.profile.name or Items.profile.name

[carmine mirage]

in a system where you need to link entities and detect which entities are linked

i really would suggest a fully-score based id system 👀

[final crater]

me too

it is way more efficient than doing constant macro execution or nbt checks (the two heaviest and most performance impacting things)
