Ive been trying to edit the Nbt of an entity and I tried searching on here and couldnt get any of the methods to work. This is my script as of right now.

ForgeEvents.onEvent("net.minecraftforge.event.entity.living.BabyEntitySpawnEvent", event =>{
    try {
        let mob_whitelist = [
            "aether:sheepuff",
            "deep_aether:quail",
            "aether:phyg",
            "aether:moa",
            "aether_redux:shimmercow",
            "aether:flying_cow",
            "aether:aerbunny",
        ] 

        event.parentA.mergeNbt("{Age:24000}")
        event.parentB.mergeNbt("{Age:24000}")
        

        // this part isnt important to the support ticket, and probably isnt staying anyways.
        if (mob_whitelist.indexOf(event.child.type) > -1){

            if (JavaMath.random() > 0.10){

                console.log("A " + event.child.type + " was removed")  
                event.setCanceled(true)
                return
            } 
        }
    } catch(e) {
        console.log(e)
    }
})

#

parentA and parentB are private fields

#

getParentA() and getParentB()

#

getChild()

rose dove Jan 8, 2025, 4:20 PM

#

Ill try that

remote cipher Jan 8, 2025, 4:21 PM

#

and mergeNbt isn’t a thing

rose dove Jan 8, 2025, 4:24 PM

#

How else can I edit the nbt?

remote cipher Jan 8, 2025, 4:25 PM

#

not exactly sure. i’m not a mod/java dev, and i honestly don’t see an obvious way how unless i’m blind

#

it looks to be this, then again i may be wrong

to get nbt (CompoundTag)

let nbt = entity.serializeNBT();
nbt.putInt("Age", 24000)
// to set / merge
entity.read(nbt)

remote cipher Jan 8, 2025, 4:43 PM

#

hmm close

#

instead of read, try deserializeNBT

rose dove Jan 8, 2025, 4:54 PM

#

Doesnt seem to work, no errors.

Nevermind there is one

remote cipher Jan 8, 2025, 5:04 PM

#

that does exist.. what

rose dove Jan 8, 2025, 5:04 PM

#

I made a mistake there

remote cipher Jan 8, 2025, 5:05 PM

#

forgot to pass nbt?

rose dove Jan 8, 2025, 5:05 PM

#

Didnt reload the script after some tinkering

#

rose dove Jan 8, 2025, 5:08 PM

rose dove ```[17:02:52] [INFO] aether_mob_breeding.js#32: InternalError: Can't find method...

That error was from a mistake on my end

remote cipher Jan 8, 2025, 5:08 PM

#

ok so does that work or?

rose dove Jan 8, 2025, 5:09 PM

#

No

remote cipher Jan 8, 2025, 5:14 PM

#

so no errors and not working BigEyes

#

my help is limited right now

rose dove Jan 8, 2025, 5:15 PM

#

hmmm

#

Ill try it on a cow just in case its the aether?

remote cipher Jan 8, 2025, 5:16 PM

#

and test that nbt just to be sure it’s what we’re looking for console.log(nbt.toString());

#

There is a "ForcedAge" variable

remote cipher Jan 8, 2025, 5:28 PM

#

ok that’s the nbt, it’s just not being set correctly 🤔

#

i mean Age was set, but is it applying to the entity? maybe after applying, serialize the nbt again and check if it actually set?

#

if nbt doesnt change deserializeNBT isn’t what we’re looking for. but i don’t see any other way. you could also try ForcedAge too

rose dove Jan 8, 2025, 5:31 PM

#

remote cipher if nbt doesnt change deserializeNBT isn’t what we’re looking for. but i don’t se...

Forced age doesmt seem to do anything to do with this

#

I set it with /data and I dont see anything happening

remote cipher Jan 8, 2025, 5:42 PM

#

question, are you meant to set age of parents or child?

#

cause if only the child, you can simply do event.getChild().setAge(24000)

rose dove Jan 8, 2025, 5:43 PM

#

parents

#

Afaik the child is born with -24000 age, and the parents are given I think 6000 and both count down/up to 0 which when its reached the child grows up and the parents to lose their breeding cooldown.

remote cipher Jan 8, 2025, 5:59 PM

#

i see

rose dove Jan 9, 2025, 11:34 AM

#

This was literally a shower thought, what if the value is being changed. But then is being set to the normal amount right after. Ill test it when I have time by changing a different value and see what happens.

#

If thats the case then I might have to use global variables to save the parents info and then have another event edit the parents nbt.
