help-development

[pseudo hazel]

yes but paper uses it more

[quaint mantle]

redstone may break if you run it on spigot.

[remote swallow]

most of the stuff spigot does async is chat messages and pre login

[eternal oxide]

Never seen it happen

[quaint mantle]

what are the differences in the spigot plugin api, paper plugin api and purpur?

the spigot plugin api will run on all server softwares.

[remote swallow]

purpur is just papers api, spigot uses strings and naming conventions, paper use bullshit and adventure components

[quaint mantle]

but why would i use paper api and potentially give up some compatibility?

[pseudo hazel]

and everything thats forked from spigot will also run spigot plugins

[quaint mantle]

i am aware of that

but

[remote swallow]

if you need paper features but want spigot compat use paperlib

[crimson relic]

if you dont care

[pseudo hazel]

because paper api has more functions

[quaint mantle]

what exactly does the paper api provide that spigot does not?

[eternal oxide]

not really the place to ask

[quaint mantle]

sorry if i am asking too many questions but i am sort of curious and might even say eager to learn.

[pseudo hazel]

idk , but basically everything thats in the paper api is built on top of spigot

[remote swallow]

from peopel that have bstats enabled there are currently 126,742 paper servers and 176,652 spigot/bukkit servers

[quaint mantle]

speaking of spigot/bukkit?

what is with the different names?

[pseudo hazel]

if paper is a fork of spigot does that mean that out of 180k servers 120k are paper?

[crimson relic]

different thing, different name

[remote swallow]

spigot is the server software, bukkit is the api, craftbukkit is the impl

[pseudo hazel]

or are those stats separate

[eternal oxide]

seperate

[pseudo hazel]

i see

[eternal oxide]

each fork reports as it's own

[quaint mantle]

spigot is the name of the software that packages the bukkit api?

and craftbukkit is the implementation?

what does it mean when you call it an implementation?

can you elaborate more?

[remote swallow]

in bukkit a load of the classes are interfaces

[eternal oxide]

implementation is the code which runs

[remote swallow]

because it relieson version specific

relies on

[quaint mantle]

i see, so an abstract layer of sorts between minecraft native source code and bukkit?

[eternal oxide]

yes

[quaint mantle]

as minecraft source code changes, the craftbukkit implementation is adjusted.

providing an api for bukkit developers to use and maintain.

[pseudo hazel]

yes and the api stays mostly the same to achieve cross compat

[quaint mantle]

intriguing.

[remote swallow]

and stuff isnt generally removed

just deprecated

[eternal night]

🙃 sadly

[remote swallow]

you dont get to talk paper boy

[eternal night]

[quaint mantle]

i have recently been trying to learn modding with fabric and i recently got to learn that the minecraft source code tends to change a lot.

[remote swallow]

yeah

[quaint mantle]

i see the importance of craftbukkit.

[pseudo hazel]

yeah a lot of changing code has up and downsides but for modders and plugin devs its mostly downsides haha

[quaint mantle]

but if i were to ask, what server software would be best, i suppose there might not be an universal answer in this case.

[pseudo hazel]

thats why we need the apis to make it managable

no

[quaint mantle]

that might have been one of the reasons i decided to ask these questions.

[remote swallow]

no not really

[quaint mantle]

but which would you prefer?

[pseudo hazel]

like I said if there was one best version everyone would use it

[eternal night]

Well if you want pure vanilla experience, fabric

[pseudo hazel]

I personally have a paper server but I make plugins using pigot api

[remote swallow]

yeah

i normally always run paper for perf but refuse to touch the api

[quaint mantle]

i personally use paper servers as well with spigot plugins.

but what about purpur?

[eternal night]

has very specific stuff if you need it

[remote swallow]

havent really used it much, cant say

[quaint mantle]

the new server software that aims to be highly customizable?

what are your thoughts on that?

[pseudo hazel]

i never used it

[eternal night]

if you need the features, nice

if you don't, meh

[remote swallow]

theres so many forks of paper its hard to keep track of

[crimson relic]

not big enough to matter imo

[eternal night]

purpur is getting somewhat big

[pseudo hazel]

big how

[eternal night]

its a nice fork with a somewhat specific userbase target

[remote swallow]

those are the things we steal and put in our lib

[quaint mantle]

yeah i have seen people use purpur a lot recently.

[pseudo hazel]

as in terms of popularity?

[eternal night]

yea

[eternal night]

bstats puts them at ~7% or somewhere in that ballpark

yea

[quaint mantle]

by the way, might be kind of off-topic for the theme of this discord server?

[remote swallow]

this is on essx

[quiet ice]

purpur is one of the (if not THE) largest paper forks

[quaint mantle]

but since minecraft modding is pretty popular, is there an api that i could use to create minecraft mods, as sort of a well-maintained abstract layer perhaps?

[eternal night]

sponge I guess ?

[quaint mantle]

i tried to do modding with fabric and it is so much more difficult compared to making plugins for spigot.

sponge?

[remote swallow]

did tunity get merged into paper

[eternal night]

spongepowered

yea tunity got merged

[quiet ice]

Yep

[crimson relic]

i dont find fabric too hard tbh

[quiet ice]

Sponge is the bukkit of forge

[pseudo hazel]

well modding tends to be more complicated because of what you can do with it

[quaint mantle]

its just reverse engineering the source code that is difficult.

[crimson relic]

?

[pseudo hazel]

the way I see plugins can only really extend vanilla features while modding can actually create new ones

[quaint mantle]

and minecraft is pretty complicated in terms of its implementation of its gameplay.

[quiet ice]

I personally find Mixins and the lack of a proper event handling API to be the main painpoint of modding

[quaint mantle]

plugins mostly modify behavior, not state in a large sense, is how i perceive it.

[pseudo hazel]

yeah I like plugins because of their events

but I like modding in terms of possibilities

[quaint mantle]

yeah, the event based api is kind of easy to work with.

[quiet ice]

However as someone that is modding some other game written in java, I can fully understand not taking the time of adding hundreds of events. It simply takes far too much time

[quaint mantle]

i really prefer event based programming lately.

even in node js, i prefer libraries that have abstract event based programming.

[regal scaffold]

Hey, where is information regarding secure/not secure chat messages. Is it even worth making chat messages be secure?

[quiet ice]

not worth it

[quaint mantle]

what game is it?

[pseudo hazel]

yes but keep in mind that with everyhting being event based you can lose sight of the actual structure of what you are making

[quaint mantle]

if it is appropriate to ask?

[quiet ice]

Galimulator, I can safely assert that you haven't heard of it because it's community is TINY

[regal scaffold]

All I needed to know. Doesn't really affect much anyways

[quaint mantle]

i think a good understanding of game mechanics should be important.

[pseudo hazel]

well yeah but thats not really relevant to what I said

[quiet ice]

Well I personally am only working like 10% of the time of actually implementing api stuff

[quaint mantle]

yeah, um, might be the first time i am hearing about it.

[pseudo hazel]

I was talking about the structure of your own code

[quiet ice]

70% goes to the buildchain and the remaining 20% goes to fixing bugs and updating stuff

[quaint mantle]

yeah, event based programming might have its upsides and downsides, depending on what you are implementing, but it makes it so much easier, overall, is what i have found.

[pseudo hazel]

yeah

I agree

I use a combination of event based and just normal OOP and a sprinkle of functional programming in some classes

just depending on what part of the code needs to accomplish

[quaint mantle]

OOP is sometimes pretty complicated though, abstract classes and objects, templates or generics, that is probably why I find modding so difficult.

[pseudo hazel]

I usually write from the perspective of using the code which can make certain methods seem cluttered

yes so I try to minimize that stuff when writing my own code and only use those things you mentioned at the edges of where my code touches the api

[quiet ice]

Meh that isn't something I have found to be particularly complicated in practice

[pseudo hazel]

but like generics and abstract classes are just something you need to know in general

[quaint mantle]

maybe you know more acquainted with reverse engineering other people's code i suppose.

i personally do sometimes find difficult to work with apis that are might be very subjective and abstract and don't provide much context for how things work.

i struggled with python django for that reason, back when i started out with web development, since i did not really know how the web really worked.

but it might be easier to work with since it may have a lot of abstractions and methods in place to make the code less repetitive perhaps and prevent NIH syndrome.

[pseudo hazel]

i get that

my whole plugin is NIH since I dont use any libs other than the default one under the guise of trying to learn how everything works for myself

and for fun ofc

but like ultimately it just takes me more time to debug implementations on systems that other people have already made that work perfectly fine but that I want to implement myself just for the sake of it

[quiet ice]

I myself am sometimes kindof forced to reimplement other libraries

Sponge's Mixin and the Eclipse's Aether (the maven resolver) are the two largest libraries that I am currently rewriting/reimplementing

And let me tell you: It's not a weekend project, it's a project of a lifetime

[old totem]

Hi, I do not set values for the armor stand. How can I solve this problem? Works only .setLocation(); (Version 1.16.5)

EntityArmorStand stand = new EntityArmorStand(EntityTypes.ARMOR_STAND, world);

stand.setLocation(location.getX(), location.getY(), location.getZ(), 0, 0);
stand.setSmall(true);

PacketPlayOutSpawnEntityLiving packet = new PacketPlayOutSpawnEntityLiving(stand);
((CraftPlayer) player).getHandle().playerConnection.sendPacket(packet);```

[fathom idol]

Hello
Does anyone know what I need to give in the constructor with the PacketPlayOutRespawn in 1.19.3?
Where can I find the ResourceKey<DimensionManager> and the ResourceKey<World>?
https://imgur.com/a/URbiqMN

[final monolith]

Its not spawning, right?

For non living entities you need to use PacketPlayOutSpawnEntity packet.

Whats your server version?

[wet breach]

this implies there is an appropriate alternative 😛

there is an alternative to events, but that isn't really something you should incorporate into your application unless its strictly back end services stuff or provides a service

[old totem]

My server version 1.16.5

[old totem]

No, it is spawning, but it is not small

[final monolith]

ok, you dont need to worry about the entity ID then.

[final monolith]

you need to send a Metadata Packet.

PacketPlayOutEntityMetadata

Note: after the spawning packet

[quaint mantle]

aren't minecraft plugins technically back-end network services stuff?

[halcyon hemlock]

Hi guys

[quaint mantle]

bukkit api is just an abstraction layer.

[quiet ice]

oh no - services...

[wet breach]

they can be, but no. a Service back end wise would be something that is designed to provide for other servers. In which case such a thing when you wanted to be notified of changes you couldn't use event based

[quiet ice]

Don't touch services

[quaint mantle]

what is the term services supposed to mean?

when people say back-end services for servers?

servers for servers?

[wet breach]

https://www.eventstore.com/blog/service-oriented-architecture-vs-event-driven-architecture

[quaint mantle]

i have sort of just known and used that term but did not really exactly what that meant.

i am learning so many things just by talking in this server.

[quiet ice]

You shouldn't follow that paradigm - whereever it is used there is hell

[quaint mantle]

outside of the context minecraft plugins even.

[quiet ice]

Although sometimes you don't have much of a choice I guess

[wet breach]

listen to geol, he knows 😛

but yeah sometimes you don't have a choice though

usually you want to stick to Event Driven when possible, but once you start crossing the barrier of having multiple servers working together to provide a singular thing

it doesn't quite work anymore using event driven architecture

so you have to use a different design. SOA is just one of them

[old totem]

thanks!

[quaint mantle]

would a database be an example of a component that is service oriented?

[wet breach]

Depends which database, SQLite for example is designed to be ran in an individual application and not shared across multiple applications or processes

[regal scaffold]

Hey, I have a question.

Can I make a spigot plugin which can listen to any stuff I send it from a proxy (bungeecord plugin) therefore I can technically code stuff once and it will apply to all servers which have the received plugin

[wet breach]

but something like MySQL you probably could

[quaint mantle]

aside from sqlite but you can technically have multiple applications interfacing with the same sqlite database though

[wet breach]

yes and no

[quaint mantle]

allocating one process to carry out the operations.

for all other processes.

[quiet ice]

You may want to explain further there

[quaint mantle]

but then again, just use mysql for that.

but it is technically possible, is what i was trying to express.

[regal scaffold]

I actually just thought about what I wrote and I can't seem to really understand why i would need what I said in the first place. Let me think about it a bit more

[quiet ice]

If it is what I think you want to do: It's possible, but you don't want to do it

[wet breach]

without using a custom driver, yes you would need an application to be the medium between the other applications and the SQLite DB

[quaint mantle]

you might be able to just use something else to make a separate api for that?

[pine forge]

Why am i not receiving the RIGHT_CLICK_AIR action in my PlayerInteractEvent? Is that a know bug?

[quaint mantle]

but elaborate more.

[wet breach]

it is more likely in how you are listening for it, show your code so we can detect and inform of such 🙂

?paste

[undone axle]

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

[pine forge]

Im logging the action type and it does not log anything when im right clicking in the air

[quaint mantle]

or maybe not.

[pseudo hazel]

show your code inside the event please

[quaint mantle]

i have a question.

what is the most advanced thing you guys know of?

[pseudo hazel]

what does that mean?

[pine forge]

@EventHandler
    public void onClick(PlayerInteractEvent event) {
        System.out.println(event.getAction());
}``` its literally this (i commented out my real code)

[pseudo hazel]

what do you consider advanced

[quaint mantle]

the most complicated thing you know about.

[warm mica]

sqlite is def not a service. It's a part of the application itself. one of the purpose of services is to make them independent

[pseudo hazel]

my plugin 😂

[pine forge]

it is logging all types except RIGHT_CLICK_AIR

[regal scaffold]

Ok I got it now.

I know this is possible but I'm wondering if it is how I think it is

Proxy plugin:

• Has a bunch of commands made to be used on the entire proxy
• If I want to add new commands just add the logic in the proxy plugin

Server plugin:

• Just has the ability to receive the information from the proxy
• Will automatically work without updating if I add/remove commands and stuff from proxy

[pseudo hazel]

right click air probably only work if you use an item that has an interaction like a map or a bow perhaps

[regal scaffold]

Is this how it works? Or do both parts of the plugin need more advanced logic and need to be updated parallel

[pseudo hazel]

but im not an expert on that event

[pine forge]

@EventHandler
    public void onClick(PlayerInteractEvent event) {
        System.out.println(event.getAction());
}``` 

Why is this code not receiving the RIGHT_CLICK_AIR event?
Also note, that RIGHT_CLICK_BLOCK is always logged twice for some reason

[wet breach]

this is probably going to be hard to really answer because this is really dependent on ones skills. For example, I have created back in the early 2000's my own mini super computer where I could run 30 WoW instances all at the same time with no problems. Required a custom bios and I soldered I think 10-12 Motherboards together using 128pin ribbons.

[quaint mantle]

speaking of proxies, i dont know a lot about those either.

[quiet ice]

So basically you have a virtual machine on the server and the proxy plugin sends commands to the server which the virtual machine then executes?

[wet breach]

but, that is hardware more then programming aside from the custom bios

[regal scaffold]

Spigot plugin. so like a bungeecord-spigot network

[quaint mantle]

interesting because i did not understand some of the words and acronyms you used there.

but interesting.

[quiet ice]

In that case, very much possible thanks to plugin channels. The dumb approach would be to use SSVM and to give SSVM the raw event event fire hose

[pseudo hazel]

sounds like you just want to make an api for your own plugin

[quiet ice]

Alternatively you can just load anonymous classes through the sun Unsafe that then execute the code you want, but eh

[pine forge]

very active chat right here

[quiet ice]

Having proper APIs is the best approach, but won't be nearly as univerally applicable

[pine forge]

maybe there should be 2 help channels

[regal scaffold]

I see geol

[quiet ice]

Nah, won't help that much

[pseudo hazel]

when I say api it could literally just be a few interfaces

[tardy delta]

threads exist for a reason

[regal scaffold]

I've never done any bungee dev so I was just streching all I really know is messagingChannel

[quiet ice]

that won't do anything on it's own

[pseudo hazel]

thats by far the easiest way to keep your implementation separate from how you use it

well yeah

[pine forge]

Not receiving RIGHT_CLICK_AIR event

[pseudo hazel]

but I dont know enough about they want

[wet breach]

WoW = world of warcraft.
bios = is the thing before UEFI became popular basically its the architecture in how your OS knows where everything is at. (Basic Input Output System)
128pin ribbon = the cord attachment used. Like there is sata connections etc, well 128pin ribbon, means there is 128pins which you need a 128pin connecter for. Typically used for serial connections etc.

[quiet ice]

They want a virtual machine on the server

[regal scaffold]

So wait, you're telling me the way people make bungeecord commands that can be ran from any server is by putting the command logic inside the server plugin not even the proxy

[regal scaffold]

nono

[quiet ice]

Of course they don't say it by name, but they want a virtual machine

Or a proper REST-style API at the very least

[quaint mantle]

oh.

ok.

WAIT, you made your own computer?

[wet breach]

I think you are forgetting that you can connect plugins or make socket connections directly to each as well

[quaint mantle]

that could run 30 World of Warcraft instances?

[wet breach]

Yes

[regal scaffold]

True but does that mean the logic can literally go in the proxy and then pass that information to the server plugin?

[quaint mantle]

i am not sure how complex of a game world of warcraft is in terms of how much of performance it demands, but that sounds really interesting.

[wet breach]

it had an overal 25-30Ghz of processing power and like 40Gb of ram I think

[regal scaffold]

Like what I'm wondering is if one can just make a receiver plugin that receives all information from the proxy but can also run locally or network wide

[quiet ice]

Yes, if the server plugin knows how to interpret the information

[quaint mantle]

WTF?

[regal scaffold]

Oh so then the logic also needs to go in the spigot plugin

[quiet ice]

And that interpreting thing is the complicated part

[regal scaffold]

So wtf is the point of the communication then

[quiet ice]

You CAN use a virtual machine to do that, but it is extremely overkill

[quaint mantle]

40 GB of ram is a lot these days, back in the early 2000's you say?

[regal scaffold]

I understand how bungee works and the proxy style just can't understand bungee dev

[pseudo hazel]

mans just copy pasting pcs into a big blob of processing power

[quaint mantle]

oh yeah, there are different speeds of ram, like ddr3, and ddr4, nvm.

[quiet ice]

You can forget the entire idea without communication

[wet breach]

remember I soldered 10 Mobos approximately together 😛

[quaint mantle]

ah, okay.

[wet breach]

so each mobo has a slot and ability to assign IRQ's for the ram

[pseudo hazel]

but more impressive than this sounds

[quaint mantle]

you said around 40GHZ of processing power?

[tardy delta]

dang

[quaint mantle]

is that like chaining multiple cpus together or?

like one cpu

[wet breach]

each mobo had on average a single CPU, with a couple I think that had 2 slots for cpus

[quaint mantle]

going at 40 GHZ?

one cpu core, doing 40 GHZ?

[olive lance]

Yeah how do u solder 2 motherboards together wtf

[pseudo hazel]

divide and conquer

[quaint mantle]

i think the prior.

but then again, cpu frequency is not a measure of performance.

[quiet ice]

The power of zip-ties!

And a bunch of cables

[olive lance]

Velcro is I would use for that job tbh

[wet breach]

No, my setup is what you consider a Multi-CPU setup which is different then a multi-core setup. Multi-CPU mobos do exist and are still a thing because Multiple CPU's are better then multiple cores. But when you have a system that has multiple CPU's, you add up all the speeds of the CPU's and that is your overall processing power

[wet breach]

I soldered 128pin connectors to use 128pin ribbons

so that each mobo could see each other

[olive lance]

Is that like a thing people are supposed to be able to do and people know they can do

[quaint mantle]

add up or run them in parallel?

[olive lance]

Or was that some evil genius job

[lost matrix]

Multiple CPU's are better then multiple cores -> bus speed says no if you want to distribute a task. Also no L1,2,3 cache between multiple cpus

[quiet ice]

It is just something that takes time

[wet breach]

most people don't know how to do this, nor would I expect most people to even know how

I think I messed up like 5 mobos in the process

by not soldering in the right spots lmao

[quaint mantle]

i know about motherboards that allow more than one cpu.

but i did not know people did that.

so, comparing it to a modern cpu, lets say the i9 9900k, how would they fare against each other?

[wet breach]

Well, its no different if you went to school to learn computer engineering or learn how to program PCB's

etc

[quaint mantle]

i know computer science but not much about computer engineering.

i am learning new stuff here.

[wet breach]

the i9 would probably be better mainly due to modern architecture and extensions that could be taken advantage of that the older CPU's wouldn't have plus, unlike with multiple cores, you can't really have more the one cpu working on the same thing

where as multiple cores could

[quaint mantle]

you can learn more than just minecraft in this discord server, i recently discovered.

[olive lance]

What gave you the idea to do the combining of the motherboards and how did you learn to do it?

[wet breach]

the only thing that my setup from the past would probably excel at would be long running tasks that could be split between all the CPU's

in which case you could use all of the processing power more effectively

[quaint mantle]

why wont you be able to use a multicore cpu for that?

why would it be better?

is it because of thermal efficiency?

or power efficiency?

[thin lantern]

How i can make commands with autocomplete like most vanilla commands? I already done this on clientside as fabric mod but and i want to do something like this in spigot plugin

[wet breach]

trial and error and I had friends where we would make stuff like this. The hard part is just finding appropriate schematics to know the exact layout of a motherboard so you know where you could attach pins to do something. Attach pins in the wrong place and bad things happen usually, either from killing the mobo, killing other hardware like the cpu, or burning out quite a lot of the caps and resistors. Worst case scenario it lights on fire 🙂

[quiet ice]

they may not exist at that point

Or at least not in a capacity as they exist today

[wet breach]

multi-core cpu can only be so fast, and as you mentioned you have the issue of thermals.

but either system has its pros and cons

[quiet ice]

The onTabComplete method or use Brigardier like you do it in fabric

[lost matrix]

If this really interests you, then you should look into HPC

[quiet ice]

Only issue is that Brigardier integration in minecraft world is more finicky

[orchid gazelle]

Can anybody explain me how the hell minecraft sends huge block updates with for example structure blocks from server->client without lagging? My client is starting to lag with multiblock updates at around 100 blocks already

[quaint mantle]

i know but they stated that the splitting the task between multiple cpus might be better than multiple cores of a cpu.

[quaint mantle]

i see.

[quaint mantle]

HPC?

[wet breach]

high performance computing I think is what they are referring to

[quaint mantle]

multithreading probably for that?

[lost matrix]

High performance computing
Its all about clustering nodes/compute units

[quiet ice]

client

[quaint mantle]

oh client

[thin lantern]

how i can define brigadier command? In fabric i register command in event with dispatcher arument

[quaint mantle]

that is because of your limited cpu power or gpu power.

limited hardware processing power.

[lost matrix]

The data is sent only once and then stored client side in the structure

[quiet ice]

no clue. Gotta hope the other guys on here know

[quaint mantle]

client has to do a lot more than a server.

like render stuff, for example.

on a screen.

[quiet ice]

At worst I could just ping mfnalex, he's sure to know - but I think you are sure to find a solution by googling it

[quaint mantle]

play sounds on your speakers and headphones.

[orchid gazelle]

Well it needs to get rendered still. When im updating once with 100 blocks, the client is literally crying. Just gotta render the fake blocks

[quaint mantle]

clients do a lot more than servers.

[wet breach]

well also have to keep in mind that with a single CPU and multiple cores, that resources are being shared, in a multi-cpu setup some resources are not being shared. For example in my mini super computer setup, I could if I wanted allowed each mobo to act independently while still being together because they each have their own hardware and resources etc

[quaint mantle]

oh

[quaint mantle]

might be your gpu?

[lost matrix]

This problem occurs because the client also processes light updates and similar nonsense.
What is your spigot version and your overall goal?

[quaint mantle]

clients dont process lighting updates?

they are processed server-side, pretty sure

[olive lance]

Where the motherboards running 1 os combined or they were all on their own? Or you are saying you could swap between these states?

[quaint mantle]

because of mob spawning and all that

[tall dragon]

ofc they do

[orchid gazelle]

I am surpressing light updates with player#sendBlockChanges. Im running 1.19.3 and need to send a lot of blocks to the client to render them fakely

[tall dragon]

how else do they display light

[quaint mantle]

does the server not send over light maps?

precomputed light maps?

[wet breach]

My setup, they all ran under a single OS, therefore the only things that were independent were the CPU's with everything else being shared.

[lost matrix]

Are you constantly adding and removing them or do you just need a big chunk of blocks to change?

[quaint mantle]

ok i think we might be talking about different things here nvm.

[wet breach]

but you could still have them all independent on a single OS, just not windows 😛

[quaint mantle]

yeah clients process lighting updates, as in render lighting.

not sure if they also process light maps though.

for mob spawning and stuff.

in the game.

[tall dragon]

not sure bout that either

[orchid gazelle]

I am constantly changing. Sending one at the same time would spike already tho

[pseudo hazel]

no the server spawns mobs

[quaint mantle]

lighting updates are very expensive to compute

perhaps the most expensive computation that occurs when you break and place blocks.

[pseudo hazel]

the client just uses the light sources to calculate the light levels etc iirc

[tall dragon]

yea i believe so

[lost matrix]

Describe your idea pls. I think there was a similar convo a few days ago and there might
be other limitations like bandwidth depending on what you are trying to do

[quaint mantle]

or maybe the server sends over the light maps, who knows? I am too lazy to look up.

[quiet ice]

I believe it is the same convo

They just were unable to resolve their issue

[pseudo hazel]

no, the server has enough stuff to do to not worry about some light maps that the client can also compute on its own

[wet breach]

server sends the light stuff, but your client still has to receive the packets and render such things

[orchid gazelle]

I am previewing big structures, and letting the player move it actively

[pseudo hazel]

the server likely has an easy way to determine if a mob can spawn at a block and such things

[lost matrix]

Have you tried using structure blocks instead?

[pseudo hazel]

and the client has similar logoc to work out what lighting should go where depending on what the world looks like

[quiet ice]

the client executes those blocks?

[orchid gazelle]

Well no, but structure blocks won't do some things I need

[quaint mantle]

that would cause a lot of lighting updates probably.

[orchid gazelle]

I am surpressing them

[quaint mantle]

lighting updates are very expensive, i do a lot of redstone, i know a bit about that first hand.

[orchid gazelle]

Player#sendBlockChanges has a flag to surpress them

[tall dragon]

u can get around lighting updates pretty easily tho

[quaint mantle]

you may have seen redstone contraptions using powered rails instead of redstone dust, we do that to prevent lighting updates from occuring as one of the reasons.

[pseudo hazel]

or observers right?

[quaint mantle]

yep.

[quiet ice]

Alternatively you could use Minecraft's debug renderer, but I am not sure whether the notchian client support it out-of-the-box

[quaint mantle]

rails might be better because they dont add much delay.

[lost matrix]

Then dont send continuous updates but discrete ones.
Let the user pick a corner, slowly render the structure and if
the user wants a new display then he has to select a new corner.

[orchid gazelle]

That destroys the whole purpose of my system. I have already tried to split the sendings on multiple ticks, but its still spiking

[quaint mantle]

if you are ever finding yourself working on something that requires a lot of blocks to be changed all the time, find a way to prevent lighting updates from occuring.

[lost matrix]

I dont even know what the systems specifications are so this is all we can give you

[icy beacon]

why??? i swear those libraries are in central

oh ok.

nvm.

I am using a GTX 1650 on an i5-9600k overclocked and 16 GB RAM

You have name: in the libraries list

[icy beacon]

oh

[lost matrix]

I meant what you are trying to achieve ingame XD

[icy beacon]

i think i took this from some tutorial lol

didn't even notice

[orchid gazelle]

Lmao I was actually confused why my system specs would be relevant lmao

[lost matrix]

^^

[orchid gazelle]

Its previewing schematic-placements in realtime

[lost matrix]

What type of schematics?

[orchid gazelle]

Wdym? I have my own system for schematics

[lost matrix]

ok. What prevents you from using structure blocks?

[pseudo hazel]

well maybe that is the issue xD

[icy beacon]

yeah it works fine without "name", thanks Olivo

[orchid gazelle]

Rotations, animations, realtime replacing. Basicly everything about actually changing blocks inside of the schematic, not just the Position of it

[regal scaffold]

[quaint mantle]

maybe just use a custom shader or something that does not render lights?

[orchid gazelle]

I am not rendering any lights, still

[quaint mantle]

uses static lighting of some sort?

[lost matrix]

They support rotations. What do you mean by "animations"?

[quaint mantle]

no lighting updates occur, regardless of you adding your own light sources.

[pseudo hazel]

pulse, the lighting is not the issue

[wet breach]

if hardware modifications are something that really interests you highly recommend taking some courses to learn such things. It is actually really difficult to learn such things on your own especially if you lack a lot of hardware for trial and error because you will fail in doing this stuff lol. Back then, you used to be able to acquire a crap ton of computers easily because people would just throw them out, I mean probably could still do that but now there is rules and regulations that stops people from doing this freely in the US in some states lol. So I would advertise back then that I would take their old hardware off their hands for them so I had a lot of computer equipment back then and random stuff too lmao

[orchid gazelle]

As an example, lets say a windmill turning. Thats gonna get previewed and calculated correctly, so that you cannot clip into blocks with it then for example

Most important part tho is realtime changing blocks inside of the schematics

Like, for example, setting all stoneblocks to sponge

[icy beacon]

hey maybe it'd be better if you made a thread for this discussion? otherwise all the other messages will drown here

[lost matrix]

Ok and what do you need constant updates for then? How often do you update the structure being shown?

[icy beacon]

a discord thread*

[pseudo hazel]

what other messages

[icy beacon]

this channel is for a lot of people

[lost matrix]

Did you add the repo as well as the dependency?

[orchid gazelle]

Everytime the player causes an action(with a cooldown of course), like moving the cursor to a new block

[icy beacon]

and this discussion will surely be very long

[pseudo hazel]

yes

[regal scaffold]

Yeah I did but that thing seems terribly done so I'm straight up not gonna use it. I believe someone said IF is the best if not self-made one

[pseudo hazel]

well if you have any question you are free to ask

[icy beacon]

bruh

[quiet ice]

I personally prefer phoenix616's InventoryGUI heh

[quaint mantle]

i might look into it at some point perhaps, i have been interested in pc building, but that is just about it, probably not too uncommon.

[regal scaffold]

Really?

[lost matrix]

Well then there is nothing left to optimize

[quiet ice]

I tested a bunch of other GUI frameworks but they weren't great

[lost matrix]

How big are the structures?

[icy beacon]

triumph gui?

[quiet ice]

No clue, I tested out like 4 GUIs I think

[icy beacon]

xd

[pseudo hazel]

just use mine that I will release in a few years

[regal scaffold]

idk which one to use man lol

[icy beacon]

try them until you find the one for you

[orchid gazelle]

Well, minecraft does it too. They are max 10k blocks(thats a hardcoded limit, already knowing that I'll not gonna be able to preview above that in any way)

[wet breach]

pc building isn't quite the same in what I was doing lol, you could learn to do that from some youtube videos and just learning that hardware is not always compatible with everything

[quiet ice]

Since then I use the same one over and over again

[regal scaffold]

IF, ObliviateInvs, Inventory GUI

[pseudo hazel]

I made my own gui stuff, basically a single abstract class that I use to create all my other menus

[lost matrix]

Its pretty decent. But having your own gui framework is superior imo.

[regal scaffold]

May I use that steaf lol

[icy beacon]

ig

[quaint mantle]

i know, the two are completely different things, its like python and assembly lol.

[pseudo hazel]

well if you want to xD

[regal scaffold]

https://github.com/stefvanschie/IF/

https://github.com/hamza-cskn/obliviate-invs

https://github.com/Phoenix616/InventoryGui

[quiet ice]

I only really know of IF and InventoryGUI. Those are the two big guys out there

[regal scaffold]

Those are my options otherwise

[pseudo hazel]

but like right now its still part of my main plugin that im working on

[quiet ice]

oblivate-invs is obscure and I've heard about that cirrus thing, but it is still rather rare

[lost matrix]

Minecraft does what too?

[regal scaffold]

Nah you're fine steaf I'll just pick one of those

I guess IF then

[orchid gazelle]

Sending so many blocks

[regal scaffold]

Man it looks so complex tho

[quiet ice]

They do it by sending entire chunks at the same time

For other things (like explosions), you'll be able to see the shortcomings

[wet breach]

exactly

[quaint mantle]

perhaps more low level than assembly

or even machine code

[pseudo hazel]

you can look at my code if you want to get some inspiration, but its probably not perfectly done ,but hey atleast it works https://github.com/Steaf23/BingoReloaded

[quaint mantle]

you are working with actual wires and transistors lol.

[echo basalt]

My util is quite similar to IF

[quaint mantle]

circuits even.

[remote swallow]

is yours public

[quaint mantle]

maybe not that low level, but requires some understanding of it probably.

[wet breach]

it does

[echo basalt]

you can probably find it somewhere if you look hard enough

[wet breach]

however, what makes it easy to understand is if you know how analog stuff works or are familiar with mechanical stuff

while both work differently, the principles are relatively the same

[orchid gazelle]

Well then imma calculate the diff serverside and send full chunks?

[lost matrix]

What prevents you from doing this?

[remote swallow]

eyes? how do they work

[quaint mantle]

i know some discrete mathematics and that is where i learned about gates and stuff.

[quiet ice]

I guess you could, but that'd be like super cursed

[echo basalt]

menu has layers, each layer has elements that are defined by making a selection and applying an element to it

A selection is just an interface with a List<Integer> getSlots

[orchid gazelle]

Ohhh thats smart actually. So I'd translate it into them whenever im sending the update, and send it

[orchid gazelle]

But does it actually work to generate and send those temp?

[pseudo hazel]

yeah just send updates in the form of structure blocks

[echo basalt]

A layer is just a Map<Integer, MenuElement> and each element has stuff like getDisplayItem and whatever

That's literally it

[wet breach]

yeah in mechanical, gates were physical and with digital gates can both be physical or virtual

[icy beacon]

where'd you create such a diagram btw

[pseudo hazel]

use draw.io

[quaint mantle]

but there is probably so much more to it than that, lol.

[icy beacon]

ty

[quaint mantle]

or maybe that is the gist, then i might have a baseline understanding of things, aside from electrical engineering.

which i dont really know much of besides the very basics of electrical circuits.

[wet breach]

it is essentially the gist, except with the virtual you either are listening for another input, or the gate itself is equal to the input itself

which can be hard to wrap your head around

[lost matrix]

And with a bit of magic you can also support custom functionality 😄

[echo basalt]

that's not enough magic

but yeah you can do funky stuff

[quaint mantle]

is that vanilla or modded?

or some kind of texture pack?

[lost matrix]

Vanilla... I should probably continue this project. Was pretty fun

[pseudo hazel]

how did you do those things?

server resourcepack?

[orchid gazelle]

Wait so this adds items that look like the exact elements?

[pseudo hazel]

packets presumably?

[quaint mantle]

that looks cool.

[lost matrix]

Pretty much

[orchid gazelle]

Are structureblocks generatable temp on the fly just with input blockdatas or states?? And sendable easily

[pseudo hazel]

hmm I only know how to change textures, not how to change where inventory slots are and stuff

[quaint mantle]

looks not much is going on right now, i might ask my question now.

so, i was curious about proxies.

why would you use bungeecord?

not something NGINX or something else?

for routing?

and load balancing perhaps?

[lost matrix]

Never used them tbh

[quaint mantle]

i am not really super familiar with proxies and stuff or used them a whole bunch but was just curious.

[remote swallow]

how else you gonna show this in mc

[quaint mantle]

show what?

[remote swallow]

an motd

or a player count

[quaint mantle]

oh yeah, nvm.

[remote swallow]

or even tell the client that that ip is a server

[remote swallow]

[lost matrix]

Because you have builtin functionality like authentication and cross-server communication.
Also bungeecord is aware of player identities and some game functionality

[quaint mantle]

oh ok.

[pseudo hazel]

i use bungeecords chatcolor xD and chatcomponents

[quaint mantle]

so, on the topic of proxies for minecraft, what do you guys use?

[wet breach]

Nginx doesn't know random TCP stuff. It only knows the web protocols, not custom protocols built on TCP, in this case minecraft, and how to handle them appropriately. Also webservers are not designed for long running active connections either. So you need something like Bungee, you could use HAProxy if you wanted, but bungee also does something else. It is what allows you to teleport between servers because it hacks the world object for the client, and essentially to the client, all the servers are actually just worlds

[echo basalt]

menu go brr

[remote swallow]

okay so illusion

im gonna need you to close some apps

[echo basalt]

nah its fine

[quaint mantle]

oh!

the cross server switching!

yeah might difficult to implement that myself.

[lost matrix]

But you can do this if you reach your bungeecord connection limit

[regal scaffold]

Is that what redis does?

[echo basalt]

DNS round robin + a dedicated proxy that routes into bungee

[quaint mantle]

redis is a database? what do you mean?

[echo basalt]

pretty sure that's what tcpshield does

[lost matrix]

Yeah this is cool. Ive worked on a server which had pretty similar designs. It released and just died XD

[echo basalt]

made those menus in like an hour

best part is that it all synchronizes cross-server and all

[quaint mantle]

interesting and do you have a tool for putting those diagrams together like that?

[lost matrix]

just draw.io

[zealous osprey]

Damn, that looks slick

[wet breach]

careful in saying that, to some people dns round robin is bad and should never be used 😉

[echo basalt]

oh yeah that guy

[quaint mantle]

i have seen a few other proxies though, like waterfall, velocity and there is thing called floodgate too probably. What are they all about and how would they all differ if they do?

[echo basalt]

samsung

[wet breach]

surprised you remembered, lmao

[echo basalt]

I like internet arguments

it was also on that day where you sent me food money

[pseudo hazel]

how do you make those big buttons?

[echo basalt]

texture packs

annd fancy code

[pseudo hazel]

whats the code like

[lost matrix]

fancy

[pseudo hazel]

is there an open source project?

[wet breach]

so I remembered from that argument in what I was trying to remember in why dns load balancing is acceptable since they were talking about dead IP's. That is, that is what ip failovers are for, where you can literally re-assign where the IP routes.

[echo basalt]

man was like "nuuuu my fancy 10k$ switch does that"

[wet breach]

lmao

[lost matrix]

You click on a location and do stuff... its not too complicated.

[quaint mantle]

oh, basically just listening to mouse pointer locations?

[pseudo hazel]

but also with like the hover and stuff

[quaint mantle]

but wait, how did you render that?

[lost matrix]

mc doesnt send exact mouse locations

[quaint mantle]

how did you render it like that in the first place?

[echo basalt]

assign a custom character to a png and put it on the gui title

then the slots and all are just lore

on invisible items

[lost matrix]

old school: Retexture items and place them
new school: Replace font characters with textures and rename the inventory

[pseudo hazel]

damn thats pretty clever

but how do you remove those slot outlines you get when hovering over an inventory

[quaint mantle]

wait

i did not get that

[echo basalt]

the outlines apply directly to the item texture and not the whole slot

if you make the items invisible, or like a 1x1 transparent pixel, you don't need to worry much

[quaint mantle]

you are basically assigning custom textures for each character in the inventory title and rendering that?

[echo basalt]

pretty much

most of the guis on my demo are just a single character

[pseudo hazel]

oh

[echo basalt]

anything dynamic like 7smile7's need multiple

[quaint mantle]

and how do you detect the location of mouse clicks?

[echo basalt]

well

you don't need to

[remote swallow]

math probably

[echo basalt]

buttons are matched to slots underneath

[remote swallow]

how would you handle people clicking that tiny gap between items

[quaint mantle]

OH, the image renders over the inventory slots?

[orchid gazelle]

What resolution can these get max?

[echo basalt]

yeah

[quaint mantle]

this is pretty elaborate.

[wet breach]

there is specific sizes to make them fit for the slots, but like I don't think there is really a limit for the actual textures because you can make them go off the screen XD

[quaint mantle]

i have probably never seen this before and it may even be the first time and might even be learning something about how about i could use it!

[lost matrix]

But you might need to define characters with negative size to properly shift the images to the left or up.
It has been quite the hustle to build a proper abstraction over all this gui stuff.

[echo basalt]

I just make a very good GUI system

and a very good shifting system

and then try mixing them together

and manually align stuff a bit

[quaint mantle]

sounds like a lot of work.

[pseudo hazel]

yeah I can imagine haha

[wet breach]

would be nice if you could do up some documentation for the public if there isn't any already lol

like the concept, not necessarily code wise stuff lmao

[pseudo hazel]

yes I would love to read more into this too

[wet breach]

I think that is going to be my next website, just a collection of documentation on concepts

[regal scaffold]

Does anyone have a example of a GUI setup they made using IF XML format

[echo basalt]

ew XML

[dusk flicker]

why would you want to make GUIs in XML

[quaint mantle]

what is wrong with XML?

[lost matrix]

Yeah i got it working now as well. I can now pixel shift an image with leading chars

[regal scaffold]

Because IF offers it and it's shorter than in code?

[echo basalt]

I still wonder how people can render a player's skin in game

[quaint mantle]

what is wrong with that? You already make websites with XML?

[wet breach]

Like YAML, XML is just a specification

so if someone wants to use XML I don't see anything wrong with it

[pseudo hazel]

iirc the IF github has examples of uis and their xml code

[lost matrix]

Im stoked for this

[regal scaffold]

Yes it does

[zealous osprey]

ye

[quaint mantle]

There isn't anything necessarily wrong with xml, it's just theres many better alternatives

[regal scaffold]

But it doesn't have examples with XML and then interacting with code

That's what I'm looking for

[echo basalt]

sounds like they're remaking a feature that has already been a thing

[regal scaffold]

Like I see the field parameter and all

[lost matrix]

Hm?

[echo basalt]

I'll let the community enjoy it for a bit before I go out there and master it

armor stands and all

[lost matrix]

Ah

[echo basalt]

I guess it isn't angular

but still

[wet breach]

most of it is based on preferences and what you are comfortable with

[lost matrix]

But can you change the scale of blocks with armorstands? 😄

[quaint mantle]

i might prefer XML over json.

[echo basalt]

hmm

perhaps

[wet breach]

xml is supported natively in quite a lot of stuff as a specification too

[quaint mantle]

json might be more compact though, in terms of file size.

[echo basalt]

retextured slime 🤔

[regal scaffold]

Does anyone have a example of a GUI setup they made using IF XML format.

Specifically how to interact with the gui elements added from the xml file in the code

[echo basalt]

people already use shulkers to offset blocks

[lost matrix]

<super-useless-info>I despise xml.</super-useless-info>

[echo basalt]

working on this now

[pseudo hazel]

so lastly if I understand this correctly, with buttons like you shown, the slots are actually laid out somewhat like this right?

but isnt there like a small gap between each slot?

[echo basalt]

that gap is smaller than you think

[quaint mantle]

that would look ike

{
  "super-useless-info": "despise xml."
}```
in json.

[pseudo hazel]

okay so its like not noticable

[lost matrix]

looks good to me 😄

[echo basalt]

or yml

super-useless-info: "I despise you all"

[pseudo hazel]

yeah

you dont even have to quote the string

[quaint mantle]

i dont really like yml.

[pseudo hazel]

thats why yml is good for human input

and xml, json is better for pc to pc communication

[quaint mantle]

reminds me of python and i dont really like python a lot right now.

[lost matrix]

imagine liking scopes being separated by spaces/tabs

[quaint mantle]

i am not particularly a huge fan of python syntax.

[hazy parrot]

json is in fact designed for that, don't know about xml

[pseudo hazel]

I mean thats already how we write books

[echo basalt]

well it's human friendly

[pseudo hazel]

well xml is designed for god knows what

[echo basalt]

yml is the python

json is the java / js

[pseudo hazel]

but I dont like to write xml by hand

[echo basalt]

it's more beginner friendly but has less potential

[wet breach]

maybe, but it isn't designed for storage, it is designed to be compact for sending information

but just note that yaml is a superset of json

[echo basalt]

xml is the html

[quaint mantle]

yeah, but aside from that, not really a fan of yml for storing information.

does anyone here prefer python programming?

[echo basalt]

no

[hazy parrot]

shouldn't be doing that either

[regal scaffold]

Does anyone have an example usage in practice of IF please

[quaint mantle]

syntax-wise.

[echo basalt]

it's time for us to make config files in NBT format

[lost matrix]

https://github.com/stefvanschie/IF/wiki/XML

[regal scaffold]

Not what I'm looking for smile

[pseudo hazel]

I have another question about the resourcepack GUI, if I have like a anvil menu I assume the name input field must always be in the same location right?

[regal scaffold]

But now I'm looking for non-xml too

[quaint mantle]

i prefer node js as my scripting language.

[hazy parrot]

main thing i hate about in js is that it doesn't have strict type system, hence autocomplete in ide doesn't work

[lost matrix]

Make a button which randomly teleports you in a 200x200 radius.

I'm confused with what you mean

Use 1.19

not 1.19.3 in your plugin.yml

[echo basalt]

me, making a website in java

[quaint mantle]

front-end of the website or the back-end of the website?

[echo basalt]

everything

[quaint mantle]

how?

[echo basalt]

there's this framework called vaadin

[lost matrix]

Well... vaadin

[echo basalt]

beat you to it

thing is vaadin has some small limitations

[lost matrix]

Not on my screen

[echo basalt]

but you can overcome them

[quaint mantle]

can browsers run java on the frontend??

[hazy parrot]

it compile to html

[echo basalt]

it does fancy conversion

[quaint mantle]

or does it compile to javascript?

[hazy parrot]

or js

[quaint mantle]

like typescript or something that.

[echo basalt]

for example vaadin doesn't have the audio tag built-in

but we can just make it ourselves

[lost matrix]

I just read something, something practice... So here is a task you can practice IF with 😅

[echo basalt]

vaadin runs on top of spring

and compiles to typescript, yes

I'm using it for my school's final project

making like MCJukebox but allows people to talk to each other with directional audio

[quaint mantle]

i dont really know much about java web frameworks, not much about spring either.

[regal scaffold]

Appreciate it but I'm looking for something different. I want to see how someone with experience manages multiple menus across multiple classes with IF

[echo basalt]

neither do I

[echo basalt]

data structures

has nothing to do with IF

[quaint mantle]

i use node js and express.js for that stuff.

[echo basalt]

you just need to know how to pass data

[echo basalt]

I hate literally everything there is about HTML and all

so I do my best to abstract it away

[lost matrix]

Ah, cant help you with that. Maybe someone that actually uses IF

[echo basalt]

the only thing I can't do that easily in java is css styling

but vaadin makes it easy by giving me a blank css file I can just edit

[lost matrix]

Yeah i was about to say

Vaadin apps often look like... Vaadin apps

[quaint mantle]

you cant get around dealing with html though, and xml at that, if you are doing DOM manipulation, probably.

[echo basalt]

and I just use tools online that generate css for me

so far I have a livestream audio source with a mute button and a volume slider

0 html code

also a dark theme button

[quaint mantle]

nice but you probably need to deal with actually html and xml for doing DOM manipulation.

or not really

depends on what you are doing.

you can just make nodes.

instead of adding innerHTML.

[echo basalt]

you mean this?

yeah that's easy

[quaint mantle]

yeah i meant innerHTML.

nvm.

[echo basalt]

pretty sure that's what setAttribute is for

[daring lark]

java.lang.NullPointerException: Cannot invoke "org.bukkit.command.PluginCommand.setExecutor(org.bukkit.command.CommandExecutor)" because the return value of "org.bukkit.plugin.java.JavaPlugin.getCommand(String)" is null```

[echo basalt]

you didn't register the command on plugin.yml

i did

no typos in when you set the executor?

Might want to double-check for typos, etc.

[pseudo hazel]

if I create an AnvilInventory using Bukkit.createInventory(InventoryType.AVIL, name) is there a way I can get the actual AnvilInventory to use getRenameText and the other methods it has?

Nah, i just wanted to look how the method is being implemented

[pseudo hazel]

I see

[quiet ice]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/inventory/util/CraftInventoryCreator.java#27 Yeah, anvils aren't implemented correctly

[pseudo hazel]

oof

amazing

so the AnvilInventory interface is useless? (in 1.19+)

[quiet ice]

It's just useless for self-created anvils

[pseudo hazel]

I see

[quiet ice]

However if you use a library that deals with that you probably can use it

[pseudo hazel]

what are those libraries you were talking about

like which ones

[quiet ice]

https://github.com/WesJD/AnvilGUI among others

[pseudo hazel]

hmm

thats a tad annoying cuz I was hoping I could use my own inventory structure with this but I guess not

oh well, thanks for your help anyways

I guess I could just take the renamed item's name but im not sure how that gets created, I assume its just in the item meta at that point

[twilit wharf]

I am checking for if a player has a specific permission using Player#hasPermission but it keeps returning true even though the player doesn't have the permission. I checked with Luck perms and it does not have the permission. I tried multiple permissions, and they all came back as true. Am I using it wrong? Is there something I am missing?

[quiet ice]

Might want to use Vault as a fallback

Which is actually meant to support permission handling

[twilit wharf]

I thought LuckPerms could handle it just fine, is there something Vault can do that LuckPerms cant?

or is like a backup to verify that LuckPerms is working.

oh wait

if I am op, do I have every permission?

[quiet ice]

Yes

[quiet ice]

Vault is a library for dealing with permission management

Alongside economy and more

[twilit wharf]

ok well, that fixed it

I forgot I was opped

[quiet ice]

happens to the best of us

[warm mica]

Check how you configured that permission in plugin.yml. Whether a permission is active by default for a certain group of people depends on its configuration

[trail lintel]

Hey guys, is there a place I can get a list of possible NMS version strings? I am getting the strings using this logic, but it seems the NMS versions don't exactly match up with the minecraft versions.

String versionString = Bukkit.getServer().getClass().getPackage().getName();
String nmsVersionString = versionString.substring(versionString.lastIndexOf('.') + 1);

[remote swallow]

yeah, nms doesnt always change per mc version

[trail lintel]

ah, I think I found a good resource for this

https://github.com/MiniDigger/spigot-resolver

[remote swallow]

thats just buildtools im pretty sure

https://github.com/JEFF-Media-GbR/JeffLib

this has modules for all mc versions above 1.16

[trail lintel]

So if I understand correctly, 1.13.X does NOT mean that the same packets will be used across all 1.13 versions. I need to pay attention to the NMS RX version as well

I guess the minor in the version number only applies to api compatibility, not packets?

[remote swallow]

yeah

[trail lintel]

Excellent =] thanks a bunch

[remote swallow]

it just depends how mojang are feeling if they change between patch versions

[trail lintel]

It sure is a lot of effort to support multiple versions haha, but I think I'm getting the hang of it

[remote swallow]

yeah

module stuff is pain

[trail lintel]

Been super interesting to learn about though

But yeah setting up these modules was PAIN INCARNATE lol

[remote swallow]

maven module stuff is pain 200

gradle stuff is somewhat better

[trail lintel]

I actually haven't used gradle before. If I wasn't a maven guy at work I may have given it a shot

never had to use modules like this before though

[remote swallow]

https://github.com/The-Epic/GradleModuleStuff

i was bored and didnt get module stuff one day

so made that

[trail lintel]

ohhh nice, always good to have a resource to look at

[remote swallow]

gradle builds faster and is easier to get your head around

100%

[trail lintel]

yeah haha I'm a maven guy simply because ive used it at work for near 5 years now (and shockingly never had to use modules this way)

a creature of habit haha

[quiet ice]

depends

The folk over at sponge certainly do not know how to use gradle

[remote swallow]

gradle files are more like code instead of millions of gradle

[quiet ice]

Fabric and Forge have similar issues. It is extremely hard to find very good gradle users

[remote swallow]

oh my ducking hell

what the fuck are sponge doing

[quiet ice]

Compiling module-infos with Java 16 and the rest with Java 8.
Depending on dependencies they shouldn't depend on.
And then they also have the issue of there being a general lack of people willing to work with gradle

[lost matrix]

understandable. I both hate and love gradle. Same with maven.

But the community of maven is just about 10 times bigger so you get more support usually

[remote swallow]

gradle is great but docs are shit

maven is awful but docs are great

[trail lintel]

at least its not cmake 😉

I have had some TIMES with cmake lmao

[lost matrix]

Oh yeah. I actually completely abandoned C++ because of cmake.
Rust has a much superior build system

[remote swallow]

we are all choosing to ignore sbt is a build system

[twilit wharf]

I just had op and that caused it

[quaint oriole]

Anyone know how I can round a double up to .5 or down to .5? For example 3.2 = 3.5, 4.9 = 4.5

All I figured out was how to round it to 1 decimal number

ohh

its so simple

damn, thanks

true

[tardy delta]

lol

[twilit wharf]

Is there any way to detect when a permission is added to a player? I want to adjust something based on a permission and a runnable seems too inefficient. Is there an event or a better way to do it?

[eternal oxide]

I wrote a plugin for that., Look on spigot and the source is on Git

[trail lintel]

Guys, is there a way to do a mass build of multiple spigot versions with build tools? Because of the NMS differences I'm going to need to test not only on each major-minor version, but literally every single patch version as well.

and I REALLY dont wanna run build tools 37 times lmao

[twilit wharf]

could you provide link?

[remote swallow]

https://www.spigotmc.org/resources/permtrigger.82779/

[eternal oxide]

^

[twilit wharf]

thanks

[kind hatch]

AFAIK, no. You’ll have to run it for each and every version. That said you could just open multiple terminals and run separate BuildTools simultaneously.

[trail lintel]

that is a fair point, I think I have a solution though

although its still tedious

I don't need to build every version, I only need to build versions where the NMS version changes https://www.spigotmc.org/wiki/spigot-nms-and-minecraft-versions-1-16/

after that, unless I misunderstand

[remote swallow]

you can

one sec

[kind hatch]

You’d have to build for every version because NMS changes with every version.

[trail lintel]

just because the NMS version changes, doesn't mean the packet that I am targeting will necessarily change. So I may be able to use the same packet handler across multiple nms versions

[remote swallow]

https://github.com/JEFF-Media-GbR/JeffLib/blob/master/run-buildtools.sh

run that file

correcting the java path(s)

[trail lintel]

lemme take a look here

[remote swallow]

you can change versions you want to build as well

[trail lintel]

oh wow, thats one hell of a bash script

[remote swallow]

theres probably a better thing for that that i dont know of

[kind hatch]

Maybe so, but you’d have to use reflection at that point since the package names change.

[remote swallow]

you can probably check screaming sandels

see what changed and where

[pseudo hazel]

I am unsure how this works exactly, I have shaded a dependency but now maven builds 2 files, the normal SNAPSHOT one and SNAPSHOT_shaded

what's the difference

[wet breach]

one is before shading, the other after

[pseudo hazel]

so I should always release the _shaded version then?

[buoyant viper]

yeah, just running java -jar BuildTools.jar --rev latest --remapped

[spice shoal]

guys i have a problem , i have tried to create a custom command for tutorial with some location , but when i use /tutorial , it teleport me only on first tplocation

[pseudo hazel]

as that is the one I was aiming to make by shading the lib

[wet breach]

typically it is the other one

[pseudo hazel]

oh okay

[wet breach]

unless you did something with the naming lol

[pseudo hazel]

well I used this readme as a guide https://github.com/WesJD/AnvilGUI

which shades it to relocate it to your own package

[wet breach]

then it should be the other one, you can open it to verify everything looks correct if you want too

[pseudo hazel]

oh good point

well they seem pretty identical to me lol

the relocation is there on both versions

[trail lintel]

Ok guys, before I go down the route of crazy town and have the version of spigot for EACH version imported. Let me ask you this

say I am working on 1.16.X right. 1.16.1 uses nms 1_16_R1. 1.16.2 uses nms 1_16_R2. Do I need to import the exact version of spigot (not the api) to send objects via packets? Or is it safe to assume that the package structure is the same across all of 1.16.X, and its merely the PACKET structure that has changed?

[wet breach]

are they both the exact same size?

[pseudo hazel]

yeah

[wet breach]

interesting, could be from another plugin

[pseudo hazel]

hmm

well this is the only one I shaded

to my knowledge xD

[trail lintel]

I guess the safe bet is just to be as explicit as possible, even if nothing really changed between versions

[pseudo hazel]

yeah I think its safest if you assume each minor version is like a completely different version

[rigid crystal]

How can i code a config file?

[tardy delta]

https://bukkit.fandom.com/wiki/Configuration_API_Reference

[wet breach]

no I meant the second jar could be the result of another maven plugin

so like if you have maven jar plugin, it will use the shaded jar after it is done to produce another jar

for example

[pseudo hazel]

I see

[wet breach]

generally I always go with whatever was the final build name

[pseudo hazel]

well for now I will just use the one without _shaded

[spice shoal]

someone know the cause?

[rigid crystal]

How im getting like 6 errors right now

[tardy delta]

dunno how if you arent sharing anything

?paste

[undone axle]

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

[rigid crystal]

It can be good to read sometimes becuse i just found out that the hole page was about config files

[wet breach]

https://tenor.com/view/hole-bighole-floodhole-gif-26448593

[rigid crystal]

Any video ore something?

[pseudo hazel]

how about the code you wrote?

like where the errors are

[rigid crystal]

https://pastebin.com/6awRB9u2
Errors is:
Cannot resolve method 'saveDefaultConfig' in 'ZytexPluginWaterfall'

[tardy delta]

ah is that bungee or smth?

[rigid crystal]

Yes

[tardy delta]

cant help you witth that then

google is your friend

[scarlet moat]

hmm, im creating custom enchants, and i have done 3 of them but i cant enchant them through anvil with books, please reply if you can help me.

[trail lintel]

bro these package names are driving me insane lmao, why would mojang include version number in your package name so I have to do an explicit import for every single minor version lmao

I notice that changes in 1.18 to a more generic package pattern

[smoky oak]

there are libraries that circumvent that

idk the name tho

[sullen canyon]

Is there any way I can change entity's direction it's looking at?
For example I have a ((CraftEntity) entity) but when I apply .setPitch it just doesn't work well actually it does but the entity doesn't change the direction of its head (even with bukkit runnable)

[terse ore]

are you near it?

being in survival?

[sullen canyon]

yea I'm a passenger of this entity

and I'm in survival mode

I apply my pitch to this entity

[terse ore]

set your gamemode to creative

and check if now the pitch is setting correctly

maybe you set the pitch but then it targets to you

[rigid crystal]

https://pastebin.com/2HNRUQ5P
Anyone now why?
My code: https://pastebin.com/ZJq3WX18

[sullen canyon]

Alright I tried with creative and for some reason it still doesn't work properly

Well it flies in the right direction

but its head

looks in a completely different direciton

[eternal oxide]

you try to save a config to a folder/file before you checked it exists

[sullen canyon]

it feels like I do setPitch(-myPitch)

[eternal oxide]

You are also trying to save a null config

Its also Waterfall so inappropriate to ask here.

[sullen canyon]

This is what I'm doing ((CraftEntity) dragon).getHandle().pitch = player.getLocation().getPitch();

and update it every tick

and it basically works but dragon's head direction is like -player.getLocation().getPitch();

for some reason

[eternal oxide]

player Location pitch is not the same as NMS pitch

[sullen canyon]

how should I apply it then?

[eternal oxide]

you should use the method setPosRot, if it exists for your entity

to pass to nms pitch pitch = Location.normalizePitch(location.getPitch())

you should be settign yaw too

        float yaw = Location.normalizeYaw(location.getYaw());
        float pitch = Location.normalizePitch(location.getPitch());

        this.setYRot(yaw);
        this.setXRot(pitch);
        this.yRotO = yaw;
        this.xRotO = pitch;
        this.setYHeadRot(yaw);    // Sync head rotation```

[sullen canyon]

my IDE says there is no method Location.normalizeYaw

I'm coding for 1.8

probably this is the problem

[eternal oxide]

yes

?1.8

[undone axle]

https://howoldisminecraft188.today/

[sullen canyon]

is there any way I can solve my problem?

[eternal oxide]

no idea, you could lookup the current normalize method

?stash

[lost matrix]

Yeah... this is the problem

[livid dove]

Anyone got experience with multicraft saving and it causing ram issues?

seems we get this giant uptick in ram usage whenever the game saves via a mutlicraft save

[lost matrix]

Wait multicraft is a server host iirc

[terse ore]

wasn't it a panel?

[remote swallow]

multicraft is a panel

[lost matrix]

Which triggers saves?

[quiet ice]

Yeah, makes sense

Many panels do that

Or rather, can do that

[warm mica]

yaw = z
pitch = y

[eternal oxide]

my code is correct

[lost matrix]

Not really the concern of a panel in my opinion but ok...
Well then its clear. It uses the ram to buffer parts of the data that is being saved.
