Editing NBT giving weird errors about missing brackets

[lean bolt]

@vocal patrol , I think this error message is a bug as there are no missing brackets that i can see. To be honest there is probably a better way to give a zombie a bow

nbt on a normal zombie with an item for reference

event.entity.mergeNbt({ HandItems:[{id:"minecraft:bow", Count: 1b, tag: {Damage: 0}},{}] })```

if i don't have the , Count: 1b, tag: {Damage: 0} bit it doesn't error but it also just doesn't give them the item

I have a line after that gives them strong potion effects that shows that it did successfully run

[gloomy oracle]

The issue is, that there's no b postfix on numbers in JavaScript

In place of 1b, use NBT.byte(1)

[lean bolt]

Ah, that's not something I was expecting

[lean bolt]

it doesn't seem to like that

[gloomy oracle]

NBT.byteTag(1)

I'm sorry

[vocal patrol]

just try Count: 1 instead of Count: 1b, if that doesnt work then just do js event.entity.setMainHandItem("minecraft:bow")

you shouldnt be doing mergeNbt for equipping items anyways as that will access the nbt of the entity through Rhino instead of using the built in java methods to parse the nbt map for you

[lean bolt]

makes sense, i just saw it when editing the nbt and didn't think

for reference Count: 1 works

[vocal patrol]

forsure, wherever there is a minecraft method to handle that stuff you will want to use it

[lean bolt]

i did not think this would be as curse as it is

is there a good place to look for methods?

[vocal patrol]

do you have probejs

[lean bolt]

no, i'll get that

[vocal patrol]

you should, it shows all methods off an object

[lean bolt]

that is what i need

[vocal patrol]

there is also a site for docs here

You can find online JavaDocs for Forge/NeoForge and Fabric by clicking the button.
If you want to see classes added by Minecraft, choose Forge/NeoForge.

If the page doesn't load, click the "Status" button or ping @hazy granite.

[vocal patrol]

a more manual lookup but is very useful for looking up to see if a class or method exists

[lean bolt]

that is perfect for when on mobile!

any clue why this doesn't seem to change the zombie.spawn_reinforcements attribute?

[left osprey]

Doesn’t the second argument need to be a UUID

[lean bolt]

didn't seem to work either

though there is probably another format i should be using

[vocal patrol]

what editor are you using?

highly recommend using visual studio code as its the best for kubejs and javascript

and you're able to get probejs typings only if you have vsc

[vocal patrol]

also it isnt "minecraft:zombie.spawn_reinforcements" it's the actual attribute name. "minecraft:generic.spawn_reinforcements" the attribute id does not contain the entity name

[lean bolt]

It says Minecraft:zombie.spawn_reinforvements in the nbt of the mob

Because only zombies have that attribute

[lean bolt]

It was just note pad. I am going to install vscode. I used it before but I had to switch from windows 10 to Linux and haven't reinstalled it yet

[vocal patrol]

oh

weird, should be generic.spawn_reinforcements i think, lemme check source code, maybe im wrong here

ah yeah im just wrong, fair enough

[vocal patrol]

second arguement doesnt need to be a uuid as it will accept any identifier

at the same time the min/max is 0/1 so adding 0.5 should significantly increase the chances

what is the other context of the code? seeing one line doesnt give us much to go off of here

also

[boreal dagger]

Never say 'it crashed', 'it errored', or 'it didn't work' without providing the full scripts and log/crash report!

[vocal patrol]

mainly im looking for the server log

[boreal dagger]

Please send your KubeJS server log. It can be found at /minecraft/logs/kubejs/server.log.
If you are on 1.18 or 1.16 it will be called server.txt.
Please send the file directly, without links or snippets.

[lean bolt]

There's nothing in the logs, no errors or crashes. Just failure. And sorry I shut down my pc as I have to get up in 7 hours. But the script is the same as this one but with a different attribute

Could the vanilla game be adjusting the value and updating it based on local difficulty

[vocal patrol]

that is not the script, it does not contain anything regarding modifyAttribute, i am asking for you to send what you currently have

[vocal patrol]

its ok, we will have to pick it up tomorrow then, nbd

also how do you know it doesnt work? the nbt of the entity does not reflect the changes in the modifyAttribute method because it adds a separate attribute modifier, unless you modify the exact attribute instance of the entity

if you want to modify the base attribute then you should instead do this js entity.getAttribute("minecraft:zombie.spawn_reinforcements").setBaseValue(1)

[lean bolt]

ModifyAttribute on line 26

[lean bolt]

I don't fully follow what you mean, i was looking at the final value. It was always in the 0.0X range when adding should have made it in the 0.X range

Maybe I was looking at the wrong place

[vocal patrol]

thats what i was asking, where are you seeing this value?

[vocal patrol]

just try this though

[lean bolt]

sorry for the delay

[boreal dagger]

Paste version of archer_zombie_server.js from @lean bolt

[boreal dagger]

Paste version of archer_zombie.js from @lean bolt

[lean bolt]

i'll try editing the base

[lean bolt]

doing this worked!

[lean bolt]

I'm going to close this ticket as all the nbt stuff is working now. I'm going to try adding skeleton projectile attack goals to the zombie which will probably become a new ticket
