[echo basalt]

well

[twilit wharf]

I am developing a system where players have a "potion bag" that holds potions. It is an actual item, and can be dropped and picked up. I was curious what would be the best way to verify that the "potion bag" is truly a potion bag, and what potions it contains. I have a few ideas, like saving the actual item to a DB and attach some sort of identification number to its lore or NBT data, or I could base it all off of what the lore say's it is and what it contains. Or, I could use a system that keeps track of the potions/potion bags inside of a players inventory (including a database). What would you say would be the best way to achieve this? (I am asking because I dont want to waste time on something that wont work or will be super inefficient)

[echo basalt]

there are like 5 pillars in my life

one of them is sleep

that pillar is very short

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[smoky oak]

item stacks have PDC, and PDC data is unque per plugin applying it to something. So just attach a boolean 'is potion bag'

check the link ig

[twilit wharf]

and then I guess I could attach a string in a readable format for which potions it contains?

[remote swallow]

?morepdc

[undone axle]

You can create custom persistent data types on your own, or use one of the many libraries available which have implemented those which match your needs. Learn about more persistent data types here: https://www.spigotmc.org/threads/more-persistent-data-types-collections-maps-and-arrays-for-pdc.520677/

[remote swallow]

using that you can apply a list

[twilit wharf]

interesting

[smoky oak]

well either that

or you can make use of that object to and from B64String and store that

[twilit wharf]

alright. Thanks for the help, I appreciate it 🙂

[pliant flame]

Oh I KNEW IT. He also contacted me at some point too

[echo basalt]

He doesn't work for free :)

[pliant flame]

Oh when he contacted me it was different kek

But cool dude

[rough drift]

@echo basalt I can't seem to figure it out, because if I multiply by 0.005 it's just slow in all directions, I can't figure out how to make movement faster in the velocity's direction and slower when against it lmao

[echo basalt]

you gotta multiply your speed

and not the player's speed + your speed

[rough drift]

entity.setVelocity(vel.add(toAdd.multiply(0.005)));

[cunning canopy]

Setting pitch, yaw and roll for minecart

[rough drift]

@echo basalt I found the issue

So Player#getVelocity always returns like 0 -0.07 0

[echo basalt]

Yeah that's gravity

[rough drift]

Yeah

but even if I move

only if I am in the air it updates the x and z

[echo basalt]

Ik

[rough drift]

is there any way to get around that?

[echo basalt]

No

Client sends packets for its own movement

You can just apply your constant vel

The client can battle it out naturally

[rough drift]

Yeah I got it working, only problem really is I want to aid the client to move against the vel if it's doing that

so I probs have to use PlayerMoveEvent, calc the vel, and store that myself

[primal goblet]

how to hide player's name tag with packets?

[past vapor]

Is there a way I can stop the primary world from saving chunks/entities, I know you can unload a world at onDisable, but that doesn't seem to work for the primary world.

[lost matrix]

Hm but this does not prevent saving on shutdown

Well then simply create a zip file and replace the world folder onLoad()

[patent fox]

EnchantmentStorageMeta bookMeta = (EnchantmentStorageMeta) book.getItemMeta();
Bukkit.broadcastMessage("Counter: " + bookMeta.getStoredEnchants().values().size());
Map<Enchantment, Integer> bookEnchantments = bookMeta.getStoredEnchants();
if (bookEnchantments.isEmpty()) return;

i have this code that checks for custom enchants on an enchanted book, but it returns an empty map?
im using EnchantmentStorageMeta#addStoredEnchant

when i try "/data get entity @s Inventory[1].tag.StoredEnchantments" it says it has the custom enchant on it

[lost matrix]

You are probably not setting the ItemMeta back on the ItemStack. A classic.

[real fable]

Hey ! I have an armor stand with a gold block ad head.
Currently, only his head is visible and that's what I want.
But the problem come when the stand is glowing, all the rest of it's body become visible,
Is there any ways to make only his head (Gold Block) glowing ?

[patent fox]

look at the last line in my message...

[lost matrix]

I see. Is it a custom enchantment or a vanilla one?

[patent fox]

custom

[lost matrix]

I would have to look that up but im guessing that the spigot method does not account for custom enchantments
depending on how they are applied/registered

[lost matrix]

Try setting it as a marker

[real fable]

Any documentation page ?

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/ArmorStand.html#setMarker(boolean)

[real fable]

Thanks a lot 😄 !

[real fable]

It worked !!
But now the custom name is on the stand feets,
I assume that it can be because of the new very small collision box making the top of it's head at his feet
Any ways to deal with that ?

[past vapor]

Deleting region, entities etc on disable worked fine 👍

Wasn't aware that worlds finish saving before plugin onDisable is called

[lost matrix]

Not really. You can create a second AS above for the name display

[real fable]

Okay ! Thanks for your help ^^

[alpine swan]

is there a way to remove 1 of an item from an itemstack

doing setamount(x.getamount()-1) works but wont remove the item if theres only one left

or should i just do an if statement and set it to null/air if theres only 1

[lost matrix]

What version are you on? Because in newer versions you can simply reduce the amount and the item gets removed.

[alpine swan]

1.8.8 (dont just say to update the version)

[cunning canopy]

Is there a way to set yaw and pitch of a minecart without it resettling itself?

[lost matrix]

?1.8

[undone axle]

https://howoldisminecraft188.today/

[alpine swan]

bruh

[lost matrix]

Use ancient APIs -> deal with the consequences

[cunning canopy]

If you want lower versions you gotta deal with the consequences

[alpine swan]

if im using an old version, i know well that its old

[cunning canopy]

Yes, but then it's also up to you to deal with your item stack count removing and not spigot

[tardy delta]

just write an if statement then

[lost matrix]

1.8 is slowly vanishing every day and it makes me happy. Last time i checked it was 7% and now only 5.7%

[tardy delta]

where can i download 1.1?

[cunning canopy]

Is there a way to set yaw and pitch of a minecart without it resettling itself?

[pseudo hazel]

I would still like some help with this as I havent been able to solve it

[remote swallow]

are you shading it

maven = scope compile
gradle = compileOnly to implementation

[pseudo hazel]

oh I was using provided

since I did that for my other dependencies too

[remote swallow]

provided means the classes will be found, eg like spigot-api. compile means the classes are added into your jar

been as they dont exist on the server

[pseudo hazel]

hmm I see

still doesnt work

let me share my pom

ohhhh

[pseudo hazel]

I want the decentholograms plugin to work

[remote swallow]

its dh, that should be scope provided but needs the decentholograms plugin on the server

[pseudo hazel]

oh

thats annoying

[remote swallow]

yeah

[pseudo hazel]

is there a way to avoid that?

[remote swallow]

not many standalone hologram plugins exist

[pseudo hazel]

like ideally I just want users to just download my one jar file to use the whole plugin

hmm

[remote swallow]

there is a way to supply the plugin to the server from inside your jar but idk how that works

[pseudo hazel]

hmm

sad

maybe I will just another hologram lib

do you know any others?

[remote swallow]

decentholograms is the only good one that i know of

[pseudo hazel]

yeah thats what I fear

oh well, I guess I will have to make something quick myself 😛

[remote swallow]

holographic displays exists but doesnt support all features dh does

[pseudo hazel]

hmm

it looks good enough for me

thanks

oh

wait nvm it also doesnt work xD

same issue

im already tired of this dependency bs, I guess thats my up till now all the stuff I wrote doesnt rely on them xD

I will just make something myself

[rough drift]

Checking a project that uses 1.15.2 nms, what is Block.n on that version?

[sterile token]

Why the heck mongo doesnt allow parsing integer nor doubles? Is there something broken on new updates?

[tardy delta]

uh i forgot but does mongo have getDouble or smth?

im thinking about ((Number) x).doubleValue()

[sterile token]

Yeah its has the method for getting int and double vlaues, but its throwing an exception

I thinking lib is broken or something like that

[tardy delta]

what ex

[primal goblet]

how to let the armorstand in sneak state i need to change his nametag's opacity

is there's any method or packet?

[sterile token]

ClassCastException: class java.lang.Double cannot be cast to class java.lang.Integer (java.lang.Double and java.lang.Integer are in module java.base of loader 'bootstrap')

But what makes me laguth is that i never adding a integer to a double field

[tardy delta]

uh its a double then

and youre trying to get it as an int

[sterile token]

Doesnt make sense tho

I will clear the whole db and re check my code again, maybe the issue is with the db documents

With latest java driver

[sterile token]

Right

But why wont work for document? Doesnt document already provide that?

[tardy delta]

doesnt document allow get("val", Number.class).doubleValue()?

[lost matrix]

Why would your ever use documents?

[sterile token]

Hmn, what do you use tho?

I just that mongo has 3 ways of using it, documents, schema things and ORMs

[lost matrix]

I implement a good Codec<T> and then use a MongoCollection<T>

If that wasn't good enough. Read up on how discord does markdown formatting. https://support.discord.com/hc/en-us/articles/210298617-Markdown-Text-101-Chat-Formatting-Bold-Italic-Underline-

Yeah your code should do exactly that

you mean its ok?

Does your class implement listener?

Also please mpiza if you will ask for help, provide thw hole issue and code too, if not its imposible to get helped

[cunning bane]

how can i see it?

[lost matrix]

Restart your server. And try again....

[hazy parrot]

It have onEnable, so I assume it extends JavaPlugin

[lost matrix]

He would not be able to register it otherwise

[sterile token]

right, he wont be ever having the exception if listener wasnt registered

[cunning bane]

sry but im not fast in learning

[vivid skiff]

I tried, the is this error to org.bukkit.event.EventException: null

i only have the class i pasted using that event

[sterile token]

But did you learnt the lang where you are codding?

[lost matrix]

Well JavaPlugin does not inherit from Listener. Only from CommandExecutor

And also ?paste your whole code

[cunning bane]

it is my first time in my life 😄

i right too much to not forget

[kind hatch]

Exactly, so they still need to implement Listener. Even if they are using the main class.

[sterile token]

Yeah we know, but if he didnt register the listener, the exception wouldnt appear

[kind hatch]

The IDE might throw a warning, but it'll compile regardless.

[hazy parrot]

It does not? 🤔

[lost matrix]

I have never seen a more useless exception. What java version are you running?

[tardy delta]

it does

[sterile token]

Yeah, spigot exceptions are pathethic i can agree with you

[kind hatch]

He's running paper.

[vivid skiff]

java 11

[sterile token]

?whereiam momment

[lost matrix]

Yeah but they already registered 'this' which would be a compile time error if the class wouldnt implement Listener.
Thats why i assumed he already implements Listener.

[tardy delta]

[hazy parrot]

I was reffering to Listener interface, was sure that JavaPlugin implement it

There is no such thing as "spigot exceptions". It just depends on your jvm

[tardy delta]

google it

[river oracle]

No bruh, you englishes talks really bad because you dont use correctly the lang

It's called slang. Spanish also has it.

I'm not English xD

I'm American

you sound like the dude that wrote "the dirty of the water" on his test instead of "water pollution"

Well we cant help you at all with this...
Add a huge try catch block around your method and catch Exception
Print the stack trace and show it.

How else am I going to pad my word count? lol

it was a written one and it was full of cringe stuff

"i talk the same speed as my mom"

[sterile token]

okay, definitly mongo is broken, i have done the whole codec for working with Mongo Pojos, and stll persisting the parsing issue

Maybe has to do with the driver server or cliente, im not sure i will make a issue request tho

[tardy delta]

weak, just add random text with the white background

[kind hatch]

That's the easy way out.

[rotund ravine]

Englishes is not that.

[tardy delta]

🙄

[vivid skiff]

This error appears at random, the plugin work correctly for like 5h hour or more and at random it starts giving this error

[sterile token]

5th time we tell you, provide your WHOlE code please!!!! - sorry but you already stressed me

[kind hatch]

The error is an ArrayOutOfBoundsException, so wherever you are dealing with arrays, I'd start there. Did you make any changes recently? Also a good place to check.

[lost matrix]

Scroll up to the first occurrence of this error and see if the additional info is not truncated

[sterile token]

m 100% that he is not sending the stracktrace, and just copy-pasting some part of it

[lost matrix]

This is going to be a search for a needle in a haystack if we dont know where the exception comes from...

[tardy delta]

just throw the whole latest.log in a paste

[vivid skiff]

I tried to check the Arrays but i don't know exactly what to check

[sterile token]

It was the firs thing i told him, but he didnt listen... 😬

[lost matrix]

I strongly suggest getting a proper stack trace. Then we can solve this in <2mins. I promise.

[kind hatch]

True, but I've had useless exceptions thrown before and I know it came from a recent change. It's likely to be a similar case here.

[grand flint]

Will too many armour stands, custom mobs lag out my server?

[rotund ravine]

Maybe

[vivid skiff]

I don't know how to trigger the error, so it will need time

[kind hatch]

Too much of anything can lag out a server. Just depends on how much data is put onto each armorstand.

[sterile token]

All depends on your server resources and how you code it, ram mememory you assigned, etc

[grand flint]

Like around 10,000 armour stands, being animated, moved and actions at a time

[lost matrix]

Armorstands are entities and eat quite a bit of computation time.
Thats why almost all advanced plugins working with armorstands only use
packet based ones.

[lost matrix]

100% will lag your server to death

[grand flint]

Could you tell me more about packed based ones?

[kind hatch]

That might change with the new display entities that are coming, but that's a future thing.

[grand flint]

What is that?

[lost matrix]

So stoked for them. Even Holograms could be overhauled then.

[grand flint]

I don't mind waiting another update if it will help with performacnce 😂

[kind hatch]

A wonderful new feature that's coming in a later update.

[grand flint]

There needs to be like 10k-20k custom mobs at a time

[kind hatch]

Geez, that many at one time just sounds like a performance nightmare.

[grand flint]

Is there better way to make custom mobs?

[lost matrix]

What are you even trying to do?

[rotund ravine]

It’s basically fake mobs etc. when it’s using packets.

[lost matrix]

Because there is no way this will ever happen

[grand flint]

Basically a modded server without mods

[lost matrix]

And what do you need that many entities for?

[grand flint]

Well when it's night time, how many mobs are around you

10-20

[kind hatch]

Not really. Sure you will likely be able to use them as packets, but it's a real entity that doesn't tick and has no collision physics. It's similar to the marker entity that exists, but they are so much more flexible.

[lost matrix]

Yeah in the neighbourhood of 10 - 50 depending on your settings.

[grand flint]

Yes, so I need the custom mbos to be like normal mobs

I want you to see them naturally around the world

Monsters at night, animals in the morning

[lost matrix]

Alright, still waiting for the calculation where you scale 10-20 to 10k-20k

[grand flint]

500-700 players

[lost matrix]

Ok

let me start right there

[kind hatch]

If you can run a single server with 500+ players on it at decent TPS, I'd be surprised if not awestruck in how you managed it.

[lost matrix]

There is no way on this earth you will ever have 500+ players on a single server.
You would need a highly optimized custom server jar to even reach 200 in a stable manner.

[grand flint]

No, we have that sorted, it's multiple servers, being copied to eachother from one main server

With a very very forked spigot jar

[lost matrix]

Spigot/Paper etc will never handle that many players. Especially not in a vanilla world.
A lobby can maybe hold 400 people if the backend runs on an extremely optimized 1.8 server jar

[kind hatch]

Then your server load is going to be relevant to each server. Find the max cap for each server, then use that for your calculations.

It likely won't be 10k for each server.

[grand flint]

But those mobs need to be disaplyed in all servers 🤔

[kind hatch]

How you do that is up to you, but the point is, they aren't all going to be on one single server. Find the individual amount per server.

[rough drift]

Thank you for this knowledge

[grand flint]

I already got my servers, and jar sorted with experienced developers, but thank you for the knowledge

Are there better ways to make custom mobs?

[lost matrix]

You will need to handle the entities in a custom (multithreaded) layer then. The server can never know of those entities or it will die.

[grand flint]

This server is so much trouble for me 😂

[sterile token]

Yeah, 10-20k of entties are too much for a single threaded server

[grand flint]

And very costy :(

[sterile token]

This happen when people do their first big project, next time you know that its not so easy as it sound

[kind hatch]

I want to clarify something. Is this like a master/slave system where all slave servers copy from the master OR are all of the servers synchronized as one?

[grand flint]

Pretty sure it's synchronized, but I would need to ask my developers

[sterile token]

Would you be a bit free, to explain this more please? Its a really interesting topic for me

[golden turret]

what it does

[grand flint]

My admin, can join from a turkey server and I join from the germany server, and we both see everything same

[sterile token]

So its a syncrhonized server if im not wrong

[lost matrix]

You basically proxy the packets in an extra layer. This is going to be very difficult.

[sterile token]

Also without a multi threaded server, will be really difficult because of enttiest high resources

[kind hatch]

Some new entities were introduced that are far less resource intensive. They also have some really cool properties like being able to scale and transform block states.

[lost matrix]

But now the entities need to know the state of the world in order to move

[golden turret]

cool

[kind hatch]

We know that cuty, but that doesnt mean your project can scale pretty well

Smile is refering to a profesional usage and future implementations

[grand flint]

I was already getting around 1000 players daily in our server before, almost everyone seemed to be interested when we introduced this

[lost matrix]

There where worse times with him. I still remember when he joined the server.
Left me speechless several times each day for weeks...

[river oracle]

I'm aware xD

I sometimes wonder how often the language barrier makes it seem dumb

[grand flint]

Well, thank you guys, I will continue working on this but I will be here often 😂

[sterile token]

arent you native speaker?

[lost matrix]

XDD

[river oracle]

Of English ofc

[quiet ice]

To be fair linking two servers isn't all that hard depending on how do you it

[grand flint]

3rd time, I already have that sorted out 🥰, thank you

[sterile token]

He is not tryingt o link only servers, he wants more

[kind hatch]

Well, it would be helpful to know exactly, but I can elaborate for both scenarios.

If you have a master/slave system, and assuming that each server is identical in specs, then the total amount of mobs per server will be identical to the master server. So if the master server has a cap of 50 players, then at max, the total amount of mobs will be 1000. Which should be fine given a standard spigot jar.

If you have a synchronized system, I hope that you have some sort of system that delegates mob spawning. Because copying from each server without proper management is a recipe for disaster.

[river oracle]

Just saying language barrier probably makes you sound more stupid then you are xD

[sterile token]

Me? Im mean im realy not inside the context, you brokn my braineds

[grand flint]

Alright, thank you I will see

[quiet ice]

Kindof new to the convo

[river oracle]

I'll dm you in spanish gimme a minute I'm not on pc yet

[grand flint]

Wait, would 10k-20k NORMAL minecraft mobs lag out?

[sterile token]

Yes ofc, entites are really resource intensive

[grand flint]

Okay, thank you

[quiet ice]

Probably not in a multithreaded env

You are using Minestom, right?

[kind hatch]

It would for most. Entities are resource intensive.

[grand flint]

Minestom?

[sterile token]

Its like a spigot, coded from the scratch

[quiet ice]

Not a fork

[sterile token]

My bad, wrong word

[grand flint]

Ah no we aren't, we have our own

[quiet ice]

And not even spigot. Spigot but coded from scratch would be glowstone

[sterile token]

But does your own support multi threaded?

We are talking about scalability, so without using multi threaded for your mc servers, you wont scale as you expect

[grand flint]

I'm not good with servers 😅
Can you tell me, what multi threaded is?

[river oracle]

tf is glowstone I've heard the name just not sure what it is

[kind hatch]

Man, that's an old one.

[sterile token]

Minestone its called the mc server coded form Scratch

[quiet ice]

https://github.com/GlowstoneMC/Glowstone

[sterile token]

Minestone is the new one, that is the old one 🤔

[quiet ice]

Not really

[sterile token]

I just heard about Minestone, never about glowstone

[quiet ice]

Glowstone is a bukkit implementation, Minestom is a multithreaded minecraft server impl

[sterile token]

And what have to do Glowstone if it isnt multi threaded, sorry im confused

[quiet ice]

Well technically Minestom is much more since it's basically many small servers running as one big server but that is an implementation detail

[kind hatch]

This can get really technical, but the simple answer is it's a feature of the CPU that lets programs split up tasks onto different threads. They will execute at more or less the same time, so it's used to speed up programs or offload intensive tasks away from the main thread.

[sterile token]

I was talking about future scalability, so i telling him that without custom multi threaded mc software he wont be able to scale how he will expact

[lost matrix]

Isnt glowstone dead? Havent heard of it for a while

[grand flint]

Oh, ye I know what threads are on a cpu, do you mean is each server cpu multi threaded?

[river oracle]

seems like it hasn't been updated in 8 months

[quiet ice]

It's mostly stuck in the past. Never got past the flattening

[river oracle]

on the github page

[lost matrix]

Well not too dead

[river oracle]

there is a pr for 1.19.3

[grand flint]

I have 6 servers, they are all multi-threaded

[kind hatch]

Most CPUs are multithreaded. The difference lies in whether or not the programs you use take advantage of it. It is a complicated thing to work with so most programs only use up to 4 cores at most.

However, they were trying to figure out if your programs actually take advantage of it.

[quiet ice]

The type of multi-threaded is perhaps the bigger question

[lost matrix]

Well minecraft for sure is not. And if your devs are weak then multithreading can absolutely hurt your performance.

[quiet ice]

If you just multithread things like work ticking to run in a parallel manner it isn't impressive

[grand flint]

Ah so, I need to split the tasks between the threads

[quiet ice]

But multithreaded block/entity/whatever ticking is impressive

[lost matrix]

Imagine the race conditions and sync issues. Ugh.

[quiet ice]

Yeah, that would be the result of many months of hard work. Hence it would be impressive

And then you have the issue that no plugin will work with such a system

You'll basically have to redo everything from scratch

Hence why Minestom does not and will never support bukkit

[lost matrix]

Btw where is the old man? Havent seen him since i got back here.

[grand flint]

Pretty sure our jar has multithreading, but again I would need to check with the devs

[sterile token]

@grand flint To summarize everything we are telling you, is that without using a well designed mc server software which makes use of multi threaded and correctly implemented, your project will not be scalable in the future. Since as you have been told the entities are intensive operations, which consume too many resources. And without an experienced devs and engeeniers it wont success

[quiet ice]

Elgar? He's still around

[lost matrix]

Yes him XD

[quiet ice]

On the other hand - 20k ticking entities are very hard to achieve

[tardy delta]

<insert minestom here>?

[eternal night]

regionalised ticking of entities would fuck plugins to a point of no return

[lost matrix]

You either need insane single core performance or create a tick skip for entities which are far away

[kind hatch]

For minecraft specifically, you need to do a little more than that. The issue with the game is mostly single threaded. So by default, it's not taking advantage of the capabilities of a multithreaded environment. This is a little problematic when it comes to server jars since they have to abide by that rule. At least for the most part.

We can make our jars asynchronous, but we ultimately have to return the results of those threads synchronously. So if you wanted to make your jar multithreaded, you'd have to send things back to the main thread anyways. Otherwise you'd have to rewrite the game and that isn't allowed. Your devs have probably already run into this.

[quiet ice]

Or at the very least it should be easy to purge large amounts of these entities to be non-ticking (which is what paper does agressively with fishies) or to just lower entity rates to be lower

Alternatively, just reduce the amount of ticked chunks (i.e. reduce simulation distance)

[eternal night]

you certainly can rewrite the game

tbh, regionalised entity ticking is doable for sure

[grand flint]

Isn't rewriting the game, like mods kinda?

[eternal night]

or generally chunk ticking

the issue is plugins

[kind hatch]

Isn't that what simulation distance is for?

Yeah but i was thinking about something more dynamical than a hard cutoff

why is this not working?

[eternal night]

the logic you extract is not that difficult to maintain

[sick ermine]

sub class

[sterile token]

I have seen an spanish dev which was punished my Mojang because he re writed a simple mc client in unity

[quiet ice]

I still expect around 2k LoSC of changes

[eternal night]

you can run whatever the fuck you want as a server

if the spanish dev writes a minecraft client in unity

and sells it

different story

[sterile token]

Is not diffcult to mantain, but think about scalability... it wont success

[rough drift]

^

[quiet ice]

And let's be honest: If it doesn't fit in a simple ASM Transformer, I ain't going to bother updating it

[eternal night]

the paper patch for offthread chunk loading is ~10k lines

so like

[quiet ice]

nah

[eternal night]

not really an argument 😅

2k lines is fine

[lost matrix]

You need to use an unsafe cast to ActionQuestRequirement<T>

[quiet ice]

I mean 2k lines in mojang code

[grand flint]

So, I can make custom mobs from armour stands, if they are multithreaded properly?

[eternal night]

oh

yea nah

[quiet ice]

There should be more in non-mojang code but that will be very static

[eternal night]

it is all very static yes

[sick ermine]

why

[grand flint]

Can plugins manage thread usage?

[eternal night]

you just redirect all of your server logic into a second implementation basically

and just use mojangs called methods as entry points

[quiet ice]

They can create new threads and use them - but they can't tell other things to use threads

[rough drift]

Fun fact, multi threading chunks is actually somewhat easy

[kind hatch]

Help clear something up. What do you define as custom? A display name? Different behavior from vanilla?

[rough drift]

Just update them at interval orders

[eternal night]

with a simple ```java
if(true) {
doOtherStuff();
return;
]

mojang code here

[rough drift]

no issues there

[eternal night]

you barely have any diff for the insertion

[rough drift]

Of course, editing the actual code, that's different

[grand flint]

Yes, it looks different, it has custom animations, it has a different ai

[sick ermine]

.

[quiet ice]

That means you have to get the class the recompile. So basically you have MCP 2.0

[sick ermine]

@lost matrix

sorry 😦

[eternal night]

hm ?

[lost matrix]

Because currently you have an ActionQuestRequirement<?> which means the generic
methods in there dont know what objects they are allowed to use. The type is erased on runtime
so you need additional checks for this. You should never have an ActionQuestRequirement<Event> btw.

[eternal night]

what do you mean "class the recompile"

[lost matrix]

Copy paste the method and ill add the fix

[quiet ice]

You are likely to change some descriptor and in that case Mixin is insufficent and raw mass ASM is sorcery. So recompilation it is

[eternal night]

well yea

obviously

no one in their right mind would do that without a proper server fork

[lost matrix]

lol

[quiet ice]

Ah right, you can just change paper's source code directly

I am a fool sometimes

[eternal night]

yeaaa

[sick ermine]

    private void increase(Event event) {
        questRequirements.stream()
                .filter(requirement -> requirement instanceof ActionQuestRequirement<?> &&
                        ((ActionQuestRequirement<?>)requirement).getTriggerClass() == event.getClass())
                .forEach(requirement -> ((ActionQuestRequirement<?>) requirement).increase(event));
    }```

[grand flint]

Guys I got tons of options here
A) give up
B) spend more on experienced devs

[eternal night]

like leafs chunk patch is pretty nicely contained

the insertions into mojang codes are as small as possible

[quiet ice]

C) Wing it and see how far you get

[eternal night]

obviously means now you have a secondary system

but that one is *fast 🚤 *

[kind hatch]

Have you looked into MythicMobs? It sounds like it would cover what you need. It's not open source, but that's never stopped decompilers before. :p
Custom mob behavior is difficult because people hardly do it.

[grand flint]

still gotta spend on devs cuz i cant do all that 😂

[quiet ice]

that is the wrong mindset

[grand flint]

I have tons of other stuff I need work on, this minecraft project is like a side project

[lost matrix]

    // Note: You need to STRONGLY encapsulate your unchecked casts
    @SuppressWarnings("unchecked")
    private <T extends Event> void increase(T event) {
        questRequirements.stream()
                .filter(requirement -> requirement instanceof ActionQuestRequirement<?> &&
                       ((ActionQuestRequirement<?>)requirement).getTriggerClass() == event.getClass())
                .forEach(requirement -> ((ActionQuestRequirement<T>) requirement).increase(event));
    }

[grand flint]

We have custom mob behaviour with armour stands, thank you though, I am just trying to make it large scale

[lost matrix]

Who needs functionality when its fast?

[eternal night]

exactly xD

tho leafs shit usually is rather functional

until you try to keep a minecart in a soulsand block

then shit explodes

[kind hatch]

Then I'd verify what kind of server network setup you have going on. Because that's going to determine how scalable you actually are.

[lost matrix]

XDD

[quiet ice]

Then it gets complicated. But unless you are selling oil or something I don't think you have the money needed for devs anyways. The type of devs you are searching for are few and far between

[grand flint]

I can change it, which do you think is the best?

[sick ermine]

((ActionQuestRequirement<?>)requirement).getTriggerClass() == event.getClass(

If it didn't have the code, the cast could throw an exception, right?

[rough drift]

Minecraft on it's way to be the most annoying possible

I have a goddamn total of 97+ tabs of github open, multiple intelli projects, trying to figure out how to register a fucking block to the block registry

Its fucking FROZEN

[quiet ice]

Chrome?

[rough drift]

No, the registry is frozen

not the browser lol

[grand flint]

opera gx struggling with 2 tabs 😎

[kind hatch]

That isn't exactly up to me as your project sort of dictates that. If you need each server to be synchronized for certain reasons, then it is what it is. However, if you have one server that you are just copying from, then it changes how you can look at it.

It just depends on what you need. What's the server like? Is it a survival world that needs to be synchronized? Or is it something else?

[rough drift]

edge being the champ and running all of my tabs

[quiet ice]

Nothing a little bit of a Unsafe can't fix

[rough drift]

Nah I am deep in NMS

I am past the point of unsafe

[quiet ice]

I mean sun Unsafe

[grand flint]

Yes, it's survival, it's basically like modded minecraft, but I want you to just join and play and feel like you are playing minecraft 2, with 500 other people

[rough drift]

Unsafe rn lookin real safe

[rough drift]

Not working either

[quiet ice]

Just unset the freeze flag through the unsafe

[rough drift]

if the registry is frozen then it literally deletes the hashmap

[quiet ice]

Then freeze it again after your modifications

If not, apply the modifications directly to the hashmap or copy the hashmap in interim

[sterile token]

Please something is not making sense

Error dispatching event PostLoginEvent(player=Alexito2060) to listener dev.alex.net.invites.bungee.listener.UserListener@3add81c4

[kind hatch]

If it's absolutely essential that the map is synchronized across all servers, then you'll need other systems to handle other logic like the mob spawning. Similar to what 7smile7 said back at the start.

[rough drift]

This gets called earlier than I can change it

[lost matrix]

I usually try to keep type safety with a Map<Class<?>, Something<?>> where something has to provide its generic as a class.
So

void <T> register(Something<T> something) {
  Class<T> typeClass = something.getTypeClass();
  this.map.put(typeClass, something);
}

void <T> consume(T event) {
  // This cast is fine because all map mutations are strictly monitored
  Something<T> something = (Something<T>) this.map.get(event.getClass());
  something.consumer(event);
}

This way i keep O(1) time complexity and im relative safe (as long as i strongly encapsulate the map).

But you are staying safe by iterating through all elements and checking for your type on each one, which is also fine.

[rough drift]

And here is the actual issue

the exception is thrown due to freezing, and I can't do shit about that

[quiet ice]

That is false.

[rough drift]

I mean I can just do a bit of funki reflection magic

[quiet ice]

I personally would just obtain the underlying data structure directly (through reflection or unsafe) and modify it without going through NMS

[rough drift]

I am already using so much reflection and NMS

[quiet ice]

Well that is obvious

[sick ermine]

almost similar methods so

[rough drift]

why didn't I just use PDC 😂

[quiet ice]

You can reduce the amount of mojmap hackery needed by using ASM to resolve field names and stuff, but that is a whole other can of worms

[rough drift]

also I can't really get the fields by reflection

since md's remapper plugin doesn't remap that

so I am just using types for now lmao

[quiet ice]

Hence ASM

[rough drift]

I.. I just wanted to texture a block lmao, welp ASM it is babiiiiiiiiiiiiiiiiiii

I have no clue how to use ASM tbh

[quiet ice]

get the bytecode for class X, then scan for what could probably be that field (i.e. do it via field accesses or something)

[rough drift]

Class literally be looking like this, I need the first nullable

I guess I can just scan until I find the first map w/ nullable

[quiet ice]

On the other hand I could probably port Starloader's @ReobfuscateReference to md's remapper plugin

[cunning canopy]

Is it worth switching to paper? Is it even that much more preformant?

[rough drift]

if you can that'd be amazing lmao, I would really need that lol

[lost matrix]

Two questions. Both can be argued for/against.

[cunning canopy]

Would you care to share some of the pros and cons?

[lost matrix]

I personally think paper is a cool piece of software

[quiet ice]

I unfortunately need to go to bed right now, but feel free to ping me in a few minutes so I'll be remembered to work on it as soon as I get back home tomorrow

[rough drift]

I could try to do it myself tbh, mind if I try?

[quiet ice]

Feel free to

[cunning canopy]

I just really need to use nms, and it seems very hard to get working with paper

[rough drift]

Only thing is that the remapper plugin already remaps strings

just not in reflection access

[cunning canopy]

But I dont know if spigots preformance will be enough for my project

[rough drift]

not in reflection access when assigning the result to a field*

[kind hatch]

What are you trying to do?

[quiet ice]

Yeah you need to know the field name, field descriptor and the owner name when remapping

[cunning canopy]

I am making fighter jets. Lots of entities. Something like 216. that needs to be updated every tick

[lost matrix]

You can make a fighter jet with just one single entity and a resourcepack

[cunning canopy]

I am aware, but I am doing it the hard way. On purpose

[rough drift]

It actually already remaps

there is just a bug when you assign the value it just doesn't

[lost matrix]

You can make them packet based. Im assuming that you are using FallingBlocks which are structured like a jet?

[quiet ice]

nonsense. If it works for read it works for write too

[cunning canopy]

Yes, but they are inside minecarts. I need to rotate the minecarts pitch and yaw.

[lost matrix]

Regarding NMS i find paper much more convenient.

[cunning canopy]

With paperweight?

Yes

    @NotNull
    public static String spaceDrawMethod = "snoddasmannen/galimulator/Space.draw(Lsnoddasmannen/galimulator/rendersystem/RenderCache;)V";

Being honest

Yes

But I also hate paper

so you know

[quiet ice]

Then write a spigot fork

shouldn't be a lot harder if you don't open source it

I just want players to not be able to drop tools unless they enter /droptools at which point they can for 10 seconds. Just to prevent accidental drops into the void

[quiet ice]

As of now this does the opposite

And affects tools as well as normal items

[analog haven]

oh no

how do I fix that

[torn shuttle]

yeah chatgpt really has no awareness of what it's doing huh

[analog haven]

I couldn't tell the difference if it did😂 I've looked for an already made plugin for this and couldn't find one so I turned to chatgpt

[rough drift]

@quiet ice Almost fixed it

Doing weird shit

[quiet ice]

not suprising

[rough drift]

IT WORKED

But not quite

Now I just need to make it send the proper block

and bim bam boom I'll be a happi boi

casually softlocked a chunk area

[quiet ice]

And now you suddenly see that you can't just add a block to a registry willy-nilly without the protocol overreacting at the same time

[rough drift]

I was already aware

I finally managed to add it to the registry

I now need to do the other 50%

[analog haven]

I was honestly shocked this plugin didn't already exist

[snow lava]

What's the EntityInsentient class from NMS, and what it does?

[remote swallow]

you shouldnt check inventories by title

[lost matrix]

Inventories dont have titles anymore. Only the InventoryView which is currently viewed by a player does

[lost matrix]

And that

[remote swallow]

keep an instance of the inventory and check if that inventory is the same

[lost matrix]

Or a Set<Inventory> if you have multiple of that type

[remote swallow]

yeah

[bold vessel]

https://paste.md-5.net/ekomiyimij.java

is this good ?

[remote swallow]

yeah

[lost matrix]

If 2 people open the inventory then the first one will break

[bold vessel]

its opened by the command /fdescc

is this going to work ?

its not a chest

[lost matrix]

If 2 people open the inventory then the first one will break

[bold vessel]

How i fix that ?

[lost matrix]

Use a Set<Inventory> and check for contains or only create the inventory once in the constructor

[bold vessel]

okk

[lost matrix]

The former method also requires you to remove the inv from the set in the InventoryCloseEvent

[sterile token]

Dont check inventory by title, u should either use inventory holder or compare inventory object

How do you serialize UUIDs with Gson?

I already created a type adapter for it, but its throwing an exception

[lost matrix]

String or 128bit int

[lost matrix]

Show the adapter

[lost matrix]

Looks good. What is the exception?

[sterile token]

at dev.alex.net.inviter.bungee.adapters.UUIDAdapter.deserialize(UUIDAdapter.java:8)

Basically is expecting a JsonObject but i dont find the cause

[lost matrix]

Your data is malformed. Make sure you delete the data before retrying.

[sterile token]

Maybe is caused because i have a uuid field on custom, which then im serializing with Gson#toJson() and Gson#fromJson() ? i edit it

[lost matrix]

Wait how are you using your type adapter?

Does the specialsource-maven-plugin already work for 1.19.3 ?

Looks like it has problems with java 19

[sterile token]

I register it thru Gson builder, and create a Gson instance which im using to then doing smth like this:

class UserModel {

  UUID uuid;
  String name;
  bla bla;
}

Gson gson = GsonBuilder.
UserModel user = new Usermodel(bla, bla);
String userData = gson.toJson(user);
UserModel serialized = gson.fromJson(userData, UserModel.class);

Im thinking the issue came when trying to seriliaze/deserialize the UUID using it as a field inside a custom object

[lost matrix]

Where do you register your type adapter?

[sterile token]

On main class

[lost matrix]

Show how pls

[lost matrix]

Serialize the data to json and show the result pls

[sterile token]

right

1m please

Okay it doesnt even serialize it into json string

Oh wait i forgot to remove a line 🤦‍♂️

Easiest way to store user data persistently in spigot? Is there like an example/docs example? Would be helpful :)

You can use the discord code block format to display code or just text in a more pleasing way:

Wdym instead? The PDC is a pretty solid choice.

[opaque latch]

Cannot resolve method 'hasPersistentDataContainer' in 'ItemMeta'

[lost matrix]

To achieve what exactly?

[remote swallow]

made with java 17 or 16 iirc, should work on 1.19

[opaque latch]

NBT data in config.yml file

[lost matrix]

Oh you are using one of the ancient Spigot versions

no

[kind hatch]

Are you using 1.13 or higher?

[opaque latch]

I just don't know what the new version should be

yes

[remote swallow]

1.14

iirc it doesnt have hasPersistent only getPersisten

[opaque latch]

Does it do the same thing?

[remote swallow]

getPersistentDataContainer will just return the container

[opaque latch]

has returns true or false

[remote swallow]

an item will always have a peristent data container

[half arrow]

just tried that, didn't seem to help :/

[opaque latch]

so can they be used interchangeably

[lost matrix]

Throw me some ideas then. Haven't been using the special sources plugin for a while.

it will always have a container, it will not always have values

Thats what i thought

You having trouble with the special source plugin?

[lost matrix]

Yes. I think i made a mistake by building the remapped files with java 19 and then trying to use the special sources plugin which only supports up to 17
But thats just a wild guess im testing right now

[half arrow]

thanks, but I already have that! Not sure where I'm going wrong - here's my format jdbc:mysql://hostname-IP:3306/database-name

[kind hatch]

You didn't in the example you gave though. What does your MySQLHelper class look like? It's probably not being formatted correctly there.

?paste the class please

But where are they coming from?

[kind hatch]

Uhh, these version numbers. I hate figuring these out. Personally, I'm still using Java 16, but writing in Java 8 for the time being. However, let me install Java 19 and I'll let you know if I have issues with it.

[kind hatch]

Yea, so currently the project I use the mappings on has several. Let me get a quick test plugin up.

[kind hatch]

Huh, I guess the special source plugin is stuck on Java 17.

[lost matrix]

Alright so ive just switched to 17, cleaned and then installed

Which worked

[half arrow]

Did you notice anything Shadow?

[kind hatch]

Yea, how did you change the version? Cause you could of just set the compiler version and still have the project be labeled as 19 in the intellij project settings.

 <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>17</maven.compiler.source>
    <maven.compiler.target>17</maven.compiler.target>
  </properties>

[lost matrix]

I've changed both

[kind hatch]

Fair enough.

You have any idea why the <java.version> tag won't ever work for me?

[lost matrix]

Alright 17 it is then. Not a big loss but still an ugly problem

[kind hatch]

Is that how it's supposed to be used?

[lost matrix]

Yes

[kind hatch]

That might explain it then. lmfao

[worldly ingot]

Yes. java.version means nothing to Maven. It's just a custom property

[lost matrix]

XD

I should actually add spigot.version to clean this mess up

Ah this looks nicer 😄
Sometimes i dont completely hate maven

[kind hatch]

Yea, your input is the problem. You are setting the 'host' parameter to "hostname-IP:3306/database-name" without replacing the values.

Smile im really confused about registering the custom codec for Mongo client

I already setup a custom codec for writing and reading

[kind hatch]

Oh I think I see part of the problem. You should be using the HikariConfig to be setting the values not Properties itself.
HikariConfig#setJdbcUrl()
HikariConfig#setUsername()
HikariConfig#setPassword()
HikariConfig#addDataSourceProperty() <---- For everything else that's not included.

HikariConfig config = new HikariConfig();
// Set the config values

HikariDataSource dataSource = new HikariDataSource(config);

[sterile token]

Properties are the one from the uri if im not wrong?

[kind hatch]

He's using java.util.Properties. There's no need to when the methods provided by HikariConfig are the correct way to set them.

[sterile token]

for example: <method>://<user>:<pass>@<host>:<port>/db?authSource=admin

[sterile token]

ohh right i catch you

[kind hatch]

You could also set the values on the HikariDataSource manually, but the config options make it easier.

[half arrow]

Okay i'll try that thanks

[lost matrix]

Im gonna treat you with one of my personal classes. A MongoDB Codec which is backed by a Gson instance:
https://gist.github.com/Flo0/2f751f875b040dae23a62379443d451e

You need to create a separate codec for every MongoCollection<V>

  // Very important to pass a good Gson instance here
  public TypedGsonMongoCodec(Class<V> typeClass, Gson gson) {
    this.typeClass = typeClass;
    this.gson = gson;
  }

Example:

    MongoCollection<V> mongoBackbone = ...;
    CodecRegistry customReg = CodecRegistries.fromCodecs(new TypedGsonMongoCodec<>(mongoBackbone.getDocumentClass(), gson));
    CodecRegistry codec = CodecRegistries.fromRegistries(MongoClientSettings.getDefaultCodecRegistry(), customReg);
    mongoBackbone = mongoBackbone.withCodecRegistry(codec);

The codec basically translates json to bson and back.

And Object -> json / json -> Object is handled by Gson

[kind hatch]

Hey 7smile, was there a reason you needed Java 19? Or are you just trying to stay on the bleeding edge?

[lost matrix]

Im using this so that i can use MongoDB like an actual Map<K, V> 😄 (With long get/put operations)

What's your code look like now?

[remote swallow]

does spigot change java version with mojank

[worldly ingot]

[drowsy helm]

you can do instanceof in swithces?

dang

[worldly ingot]

CraftBukkit jumps because it directly compiles against server internals and has no choice, but Bukkit stays compiled against 8. You can compile your project against 8 or higher

Hey wait, hold up. The is keyword. That would be a nice replacement for instanceof if you ask me.

[hazy parrot]

definetelly more human readable

[drowsy helm]

'is' is pretty ambiguous

[hazy parrot]

if (listener is EventListener)

[drowsy helm]

java loves verbose

instanceof doesnt really leave room for interpretation

how is it ambiguous 🤔

what can it mean

aside from instanceof

HashMap<int, ArmorStand> holograms = new HashMap<>();
ArmorStand hologram = (ArmoStand) location.getWorld().spawnEntity(location, EntityType.ARMOR_STAND);
holograms.put(1, hologram);

And I'd like to delete the armor stand at the key 1. How can I do this?
I tried this, but it doesn't work:

holograms.get(1).remove();

[drowsy helm]

if(a is b)

[hazy parrot]

well

ig ur right

[drowsy helm]

holograms.remove(1)

[kind hatch]

I could get behind this.

[hazy parrot]

but i feel sorry for those people 😭

[drowsy helm]

it uses key value pair not index

[worldly ingot]

Maps aren't random accessible nor indexible

[upbeat hornet]

no holograms is a hashmap

[hazy parrot]

also you can't have primitive

[drowsy helm]

yes?

[hazy parrot]

in hashmap

[drowsy helm]

hashmap has .remove(key)

[hazy parrot]

use Integer instend of int

[upbeat hornet]

oop my bad I use another key but I tried simplifying it

My key is correct

[upbeat hornet]

I want to delete the armor stand (not remove it from my hashmap)
will deleting it from the hashmap actually remove it?

[drowsy helm]

by "remove" do you mean from the world or from the hashmap

[hazy parrot]

does those ints represent index or something other

[drowsy helm]

they said its a diff key

just simplifying

[kind hatch]

No, you have to call #remove on the entity itself.

[hazy parrot]

oh i assumed they are talking that its Integer lol

[upbeat hornet]

Yeah sure. I just wanted an easy key because the actual one is a location and yeah I don't want to add stuff to that snippet to explain that I know how to get the right key

[drowsy helm]

.remove() on the entity should work

[upbeat hornet]

before and after

It clearly did not delete the first one

[kind hatch]

How did you remove it?

[upbeat hornet]

pretty much this

oohh wait

I think I'm dumb

[zenith pewter]

Is there another free plugin? The dollars here are expensive.

[upbeat hornet]

ok it works now

Had a problem with my key (was deleting it right before I try to access it)

[kind hatch]

Oh wow. I've had it for so long that I forgot it was premium. lol
I remember the outdated ones like PlotMe or PlotManager, but I don't know if many other more modern ones even exist. PlotSquared kinda took over that niche.

[zenith pewter]

If I buy the plugin are the updates free?

[kind hatch]

Yes

However they (the updates) are not guaranteed.

[zenith pewter]

I will trust the developer.

Hello guys, is there a way I can let my players choose what texture pack they want, between the dark and light theme, and then it automatically puts the texture pack on

[drowsy helm]

save their choice somewhere then when they load in use a diff url

[grand flint]

Yes, how do I send the texture pack to the user?

[drowsy helm]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#setResourcePack(java.lang.String)

[grand flint]

That is like the server properties file? It will automatically load the texture pack?

[drowsy helm]

what?

wdym

[grand flint]

You know, how if I set the URL in the server.properties, and if they have resourcepacks enabled, it loads the texture pack

Does that function load the texture pack

[drowsy helm]

the method has nothing to do with server.properties

[upbeat hornet]

I don't think it's possible to load different ressource packs for each user

the only way I see it possible is if you connect them to a different proxy and manage to get them on the same world

[grand flint]

I never said it did
