the hard part is letting your friend join without connecting them to your home network

[slim igloo]

we can skip that then, I just want to make a server to test out my plugin i coded

how should I go about that?

i appreciate each of your responses btw

[spark pagoda]

the best way is to use a plugin for your build tool, but for now you can just add your plugin to a normal server and join it using the ip ::1

[fresh timber]

is there a way to check if a command argument can be parsed into an int without outputting a ton of exceptions?

[wet breach]

this is mainly due to the fact that modern cpus have tricks to speed up such things. Whenever the JVM can, it will invoke native code which sometimes will invoke known cpu extensions

[spark pagoda]

there's a regex for it but you could just use a try-catch

[spark pagoda]

yup :) you can actually see a disassembly of the JIT compiled code with tools like jitwatch

[wet breach]

https://graphics.stanford.edu/~seander/bithacks.html

think you might like that

and maybe some others too

[spark pagoda]

i think i've actually seen that before !! it was on a stackoverflow post for the bit permutations

thank you though, i'll have to bookmark it this time :)

[wheat inlet]

Do I need to load a chunk to get the chunksnapshot

I dont really understand how they work

[wet breach]

I believe the method to get the chunksnapshot automatically loads the chunk

can't really get a snapshot of something the server doesn't have loaded

its like asking can you look at a picture of nothing

[fresh timber]

I'm trying to create a player_ec table with 7 strings: 1 uuid and 6 ec that are using base64 to convert them, but I'm getting an error. Here is the statement I'm trying to use and the image is the error.

String sql2 = "CREATE TABLE IF NOT EXISTS player_ec(uuid varchar(36) primary key, firstec str, secondec str, thirdec str, fourthec str, fifthec str, sixthec str)";

(I have also tried for all of the strings, using string instead of str)

[eternal night]

wtf is a str

[fresh timber]

bro idk I was trying different things to see if they would work instead of string

but didnt work

I did try string btw xd

[eternal night]

I mean

str is just not a datatype in any of the SQL implementations I know

[fresh timber]

ok ok I didnt know'

[eternal night]

what do you want to store in there ?

[fresh timber]

STRING

it didnt work when I tried string tho

[eternal night]

https://www.w3schools.com/sql/sql_datatypes.asp

[fresh timber]

string did not work :(

oh

;-;

I have to say the size??

[eternal night]

read below that 😅

well not really

[fresh timber]

idk the size xd

[eternal night]

TINYTEXT would hold up to 255 chars

[wet breach]

show your code please

[fresh timber]

oh ok ima use mediumtext cus idk how big it is

[eternal night]

this is just a choice of what datatype

yea mediumtext should contain pretty much whatever

[fresh timber]

ye its prob pretty big if it stores a whole inv in one string

[wet breach]

ideally you should be using the smallest type necessary

[eternal night]

👀

MEDIUMTEXT might be a bit large for a base64 inv

plain TEXT should probably workout

or just MEDIUMBLOB if you have the bytes

[fresh timber]

ye but text wants a size

[eternal night]

nah

[fresh timber]

idk the size xd

[eternal night]

you can just not specify it

[fresh timber]

ahh ok

[eternal night]

goes up to 65,535 bytes

[fresh timber]

so just TEXT or TEXT()?

[eternal night]

just TEXT

tho I presume

urgh

probably MEDIUMTEXt

just for those fuckers that have 50 shulkers

with stuff inside

[fresh timber]

ok xd

I always am confused why every mysql statement ppl write is all caps even tho it doesnt need to be

not all but mostly

[eternal night]

I mean, conventions be conventions

[wet breach]

store it as a BLOB

[fresh timber]

;-;

I just set all to mediumtext

why tho?

[eternal night]

BLOB is certainly to small form some inventories

from personal experience

[wet breach]

BLOB can store 65,535 bytes

[eternal night]

indeed

you'd be surprised what one can do with shulkers and books

[fresh timber]

xD

cant u make those like chunk ban machines with that same combination

[eternal night]

indeed

[fresh timber]

lag out server xd

[wet breach]

if you convert to base64 and then grab the bytes, I doubt you will exceed the limit for BLOB

but if you really want more room go with mediumblob, you can store 16mb worth of binary data with that

which is actually quite a lot

[eternal night]

yea mediumtext or mediumblob is my recommendation too

[wet breach]

I wouldn't store it as text mainly because in terms of space for DB text takes up more

[eternal night]

Yea, blob is cool if you can

idk they specifically asked for text

[wet breach]

well they are also new

[eternal night]

true dat

[wet breach]

and don't know about these things yet 🙂

which is why I wanted to see their code for sql

because odds are they are doing some other things wrong

or not the appropriate way anyways

[ancient plank]

Like me when I do sql

[wheat inlet]

I tried using the Chunksnapshot thingy and it works not too well,
I need to teleport my player on a solid block and air above that
cs is a ChunkSnapshot

if( cs.getBlockType(x, y, z).equals(Material.AIR)) ) //doesnt work
if( cs.getBlockType(x, y, z).isSolid() )       //doesnt work

my plugin works if I use the world.getBlock command

[humble tulip]

why are you using chunk snapshots?

are you working async?

[wheat inlet]

cause the World.getBlock could cause performance issues

[delicate lynx]

cs.getBlockType(x, y, z).isAir()?

[humble tulip]

yes but getting a chunk and snapshotting it does the same thing

the reason World#getBlock causes issues is cuz you need to load the chunk for that iirc

But you also load the chunk to snapshot it

[wheat inlet]

I am new to all of this I tried snapshots for the firsttime and hoped that the isSolid would work

[humble tulip]

What are you trying to do?

find a random spot for a player?

[wheat inlet]

yess

but with nether its annoying because getting the maxheight is always the bedrockroof

[humble tulip]

ahh

well you need to first look for air

send what you have thus far

the entire thing

?paste

[undone axle]

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

[wheat inlet]

I have it working without snapshots

[humble tulip]

oh...

[wheat inlet]

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

[humble tulip]

you sure you tried it enough without snapshots to say for sure it works without?

[wheat inlet]

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

[humble tulip]

what's this

        int cx = ((x % 16 + 16) % 16);
        int cz = ((z % 16 + 16) % 16);

[wheat inlet]

its getting the chunk coordinates

[humble tulip]

why are you doing x%16 + 16? and then %16?

x and z are your chunk coordinates

[wheat inlet]

because with (x % 16) you can get negative modulo so i add 16 and mod again

[humble tulip]

huhh??

but why?

[wheat inlet]

if (-18 % 16) = -2

[humble tulip]

why are you getting the modulo for a chunk x

World X / 16 = chunk x

you already generated a chunk x

        ChunkSnapshot c = world.getChunkAt(x, z).getChunkSnapshot();
        //Chunkcoordinates
        int cx = ((x % 16 + 16) % 16);
        int cz = ((z % 16 + 16) % 16);

[wheat inlet]

because c.getBlockType(cx, y, cz) expects 0-15 for x and z

[humble tulip]

exactly

[wet breach]

that wouldn't be the correct math

[humble tulip]

so use a for loop and loop from 0-15

[humble tulip]

oops

[wet breach]

what that would do is return the remainder

[wheat inlet]

I dont understand you I think you are wrong

[humble tulip]

yh my bad

I am not

[wheat inlet]

why would I loop from 0-15

[wet breach]

it needs to be floor(x/16)

[humble tulip]

imagine world height was 1

not 256

so we're just dealing with x and z

[wheat inlet]

yes

[humble tulip]

and let's say we're looking for an air block

say air block is at 14,2

[wheat inlet]

yes I am listening

[humble tulip]

we need to do

        for (int x = 0; x < 16; x++) {
            for (int z = 0; z < 16; z++) {
                
            }
        }

and check each x and z combination for air

[wheat inlet]

sure

[humble tulip]

        x = rand.nextInt((rangeMax - rangeMin) + 1) + rangeMin;
        z = rand.nextInt((rangeMax - rangeMin) + 1) + rangeMin;

        World world = Bukkit.getWorld(worldname);

        ChunkSnapshot c = world.getChunkAt(x, z).getChunkSnapshot();
        //Chunkcoordinates
        int cx = ((x % 16 + 16) % 16);
        int cz = ((z % 16 + 16) % 16);
        p.sendMessage("x: "+ x +" cx: "+ cx + " z: "+ z + " cz: " + cz);
        for(y = 105; y > 30; y--){
            if(c.getBlockType(cx, y, cz).isAir() ){
                if(c.getBlockType(cx, (y-1) , cz).isAir()){
                    if (c.getBlockType(cx, (y-2), cz).isSolid()) {
                        Location loc = new Location(world, x, (y-1), z).add(0.5, 0.5, 0.5);
                        p.sendMessage("You will be send to: "+ x +" "+ y + " "+ z);
                        return (loc);
                    }
                }
            }
        }

what you do here is get a random chunk and snapshot it

let's assume its Chunk(4,3)

which would have an origin at (64,0,48)

you then calculate cx and cz which according to your code is 4 and 3

that means you're only checking one row of blocks in the chunk

since youre getting the block at (cx, y, cz)

cx and cz are fixed

you need to check all x and z values in the chunk

?paste

[undone axle]

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

[humble tulip]

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

i fixed your code

see if that works

[wheat inlet]

k thank you I will look if it helps me

I am not sure if you understood what I was trying to do

I am getting a random x and z coordinate
Snapshotting the Chunk in which those coordinates are
finding out which chunkcoordinates in the chunk represent x and z (cx: x in chunk c)
Iterating from the roof downwards to find a solid block with enough space

I was never trying to find an empty block in the chunk , I was just trying to find an empty block at exactly that one coordinate(x,z)

[humble tulip]

why are you doing step 3?

[wheat inlet]

because of this

I was trying to implement getmaxHeightYAt for the nether

[humble tulip]

ohh

netherrandomLocation

that's your method name hence the confusion

[wheat inlet]

oh sorry

I am bad ast explaining my bad I guess

[humble tulip]

also you're generating a random location

[humble tulip]

see if this is what you wanted in the first place though

[wheat inlet]

well idk Its my first plugin

[wet breach]

iterating from the roof down will take longer then iterating from 0 up

[wheat inlet]

its not, I think

[wet breach]

there is more empty blocks between the ground and height ceiling which is now at 256

[humble tulip]

@wet breach are you able to confirm?

[wet breach]

then there is between the ground and 0

[wet breach]

this is correct, however there is methods that autoload the chunk at the same time too

[wheat inlet]

frostalf true I might change that I wouldnt be getting the heighest block but its not really what i cared about

uhm what my main problem was that the ChunkSnapshot seem unusable cause the isSolid() doesnt work with them

[wet breach]

I know this, but you want a solid block, so it usually better to start at a place where it would take the shortest time

[hard ether]

I've looked everywhere. Is there a way to give an entity the texture & AI of a mob already in the game?

[wet breach]

you would have to use NMS and custom entity

[hard ether]

ah, okay.

[hard ether]

yes, I'm creating a custom entity. I'll go look over NMS rn

[wheat inlet]

Thanks to everyone for the help even tho I was saying confusing shit

[wet breach]

the easiest method might be to use packets most likely

I mean if you don't need custom AI and stuff, you could just spawn the entity you want the AI of

and then use packets to disguise it as some other entity

I'm getting this error when trying to build: Could not resolve org.spigotmc1.8.8-R0.1-SNAPSHOT. could anyone help?

[jagged monolith]

Means you properly didn't add the api correctly.

[harsh badge]

Should I send the whole build file?

[harsh badge]

I should put that in dependencies instead of the CompileOnly?

Or I should put it outside of it?

[jagged monolith]

Replace compileOnly("org.spigotmc:spigot:1.8.8-R0.1-SNAPSHOT") with compileOnly 'org.spigotmc:spigot-api:1.8.8-R0.1-SNAPSHOT'

maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }

[harsh badge]

Thank you, that fixed that error but now I'm getting an error with my import net.minecraft.server.v1_8_R3.Tuple;

[jagged monolith]

An what's the error?

[harsh badge]

All my imports with net.minecraft.server.v1_8_R3 are no longer working, error: package net.minecraft.server.v1_8_R3 does not exist

[jagged monolith]

Hmm try removing the -api from spigot-api

I think spigot-api is for the newer versions

[harsh badge]

I'm getting the same issues as earlier, could something be wrong with my pom? I am using code a developer sent me could that be an issue too?

[jagged monolith]

Have you ran buildtools for 1.8.8 on your pc yet?

[harsh badge]

I haven't

How do I do that?

I can put java -jar BuildTools.jar --rev 1.8.8 in the cmd?

[jagged monolith]

https://www.spigotmc.org/wiki/buildtools/#running-buildtools Download the Buildtools jar and do java -jar BuildTools.jar --rev 1.8.8

[wet breach]

did mojang ever fix the link with 1.8.8 vanilla server jar?

if not you are not going to be able to build the 1.8 version

at least not with buildtools anyways

[harsh badge]

I am trying to run the command but it's saying it's unable to access BuildTools.jar

[jagged monolith]

Are you running the command in the directory from where you download the buildtools jar to

[harsh badge]

I just did that and now it says my Java version is to high. Do i need to goto Java 8 in order to do this? If so how can I switch back?

[jagged monolith]

What Java version are you running?

[harsh badge]

11

[jagged monolith]

11 should work, but may need java 8

[wet breach]

you need java 8 for mc 1.8

for compiling only

[jagged monolith]

Makes sense lol

[wet breach]

has to do with the decompiling process

[wet breach]

do you know if mojang fixed being able to access the vanilla server jar for 1.8?

[jagged monolith]

No idea. I haven't dealt with 1.8 in years.

[wet breach]

same, but anyways the link for downloading 1.8 either got removed or restricted

if they have not fixed it, then you can't use buildtools to get 1.8

need the vanilla server jar first for buildtools to work lol

well buildtools fetches it, but its one of the first things it does

[jagged monolith]

I'd test it but can't be bothered reverting my java haha

[harsh badge]

I get this error: Error compiling Spigot. Please check the wiki for FAQs.

try deleting everything except buildtools.jar

Deleting everything?

[wet breach]

also are you using command prompt or gitbash?

[harsh badge]

I used java -jar BuildTools.jar --rev 1.8.8

Where should I delete everything?

[wet breach]

ok but where did you use that

in command prompt?

[harsh badge]

Yes

[wet breach]

that is your problem right there

use gitbash instead

right click in the directory you have buildtools

select open gitbash

then run that command again

it should work this time

[harsh badge]

My gitbash is java 11

I need to switch this too?

[jagged monolith]

Yeah you'll need to for compiling 1.8.8

[sterile token]

that why i have 2 env vars

so i just either run java8 or java17 depending what i need to compile

[harsh badge]

How do I switch my gitbash version?

My terminal java is 8 but my gitbash is 11

[harsh badge]

I figured it out now I'm getting this: https://paste.md-5.net/bodagazusa.sql

[vocal cloud]

[rough drift]

doesn't 1.19 use 19?

[vocal cloud]

probably not as it's not LTS

[rough drift]

frick

I wanted the new features

[vocal cloud]

correct

[rough drift]

you can just use an array

ItemStack[] stacks = new ItemStack { ... };

stacks[e.getSlot()];

[vocal cloud]

I already said that lmfao

[rough drift]

two points

why are you creating a new ArrayList just to wrap an ArrayList?

why are you assigning it to an ArrayList<ItemStack> when you can simply use List<ItemStack>

and also fyi you have two ;

[glad prawn]

new new new new new new new

[wet breach]

even better is, they could just use the add method on the already created list lmao

[rough drift]

^

yep

it literally makes a new one

you should always use the weaker type if possible

even in method params/variables

ArrayList<MyThing> things; // bad, List<MyThing> can't be assigned
List<MyThing> things; // good, both List<MyThing> and ArrayList<MyThing> can be assigned

[wet breach]

well its like this really
List<ItemStack> items = new ArrayList<>();

and then they can do items.add(ItemStack)

or whatever it is they require

[kindred valley]

Artifact sorting is a bit problem on intellij

As an example, Vault API just uploads 1 more spigot api(1.13) when it is not able to detect the original version of spigot because it is not a more prioritied artifact than spigot so it always uses the 1.13 spigot. Its like hell.

Nvm you got the point

Be careful

[hazy parrot]

You can always exclude ig

Intellij has cool maven conflict thingy

[fierce whale]

Is there anyway to give permission to player?

[jagged monolith]

It's easier to use a permission plugins api. Like LuckpermsAPI if you're wanting to give permissions through code.

[wet breach]

what?

artifact priority is controlled first by the order the dependencies are listed

second, you can exclude transitive dependencies

[hazy parrot]

it sums the chars i would assume

i dont know js, but you would have to parse it somehow ig

[jolly crypt]

I found it

the 'numbers' in the array were strings and no numbers

thanks anyway

[hazy parrot]

it sums the chars i would assume

¯_(ツ)_/¯

[glossy venture]

no it makes an immutable list

its called an ArrayList but its not the same type as java.util.ArrayList

its literally an immutable list which wraps an array

[delicate narwhal]

does somebody know how i can turn on tnt duper on spigot servers???

[quiet ice]

Spigot normally doesn't disable dupes

But this is a #help-server question

[delicate narwhal]

WHAT

WHY

[tardy delta]

Arrays.asList doesnt create a normal arraylist

[glossy venture]

yeah

[quiet ice]

Spigot still attempts to be reasonably close to vanilla behaviour

Paper on the other hand - they disable dupes - but if the dupe does not exist on spigot and especially not in vanilla then there is no chance that it will be a toggleable thing unless you use another fork entirely that specialises in allowing dupes

[sinful wave]

I'm making a duels plugin, and currently I have a void world where I add arenas and teleport players there.
What would be the best way to paste in arenas to the void world? The WorldEdit API? It seems to use quite alot of performance.

[glossy venture]

maybe paste in a fixed number of arenas of each map so you always have like 50 arenas

then you just have to load them

[sinful wave]

ok, and just like adjust if i ever needed more

but i wont

[glossy venture]

yeah

you could add in a grid system

[sinful wave]

ye

i could just have lines for each

[glossy venture]

which dynamically pastes arenas if you need more

[sinful wave]

and extend the lines

how would i do that tho, i'd have a preset world

and replace the world with the preset world

everytime the server starts

[glossy venture]

public static final int GRID_CELL_W = 240; // x
public static final int GRID_CELL_H = 240; // z

public static final int INIT_GRID_SIZE = 20; // 20 x 20

public void setupWorld(World w) {
  for (int xi = 0; i < INIT_GRID_SIZE; xi++) {
    int xc = xi * GRID_CELL_W; // x coord
    for (int zi = 0; i < INIT_GRID_SIZE; zi++) {
      int zc = zi * GRID_CELL_H; // z coord

      pasteArena(w, xc, zc);
    }
  }
}

maybe smth like this

you could do this asynchronously i think

to not slow down the server start too much

[sinful wave]

nah i could just have a preset world tho?

[glossy venture]

true

[sinful wave]

like make one

also

unrelated but kinda related

once i tp two players into an arena

and the match statrs

say its uhc and they have blocks

i want them to be able to place and break blocks

but not pre existing blocks

how would smth like that look

[glossy venture]

keep a set of placed blocks

[sinful wave]

my idea was

to listen to block break and place events

[glossy venture]

and dont allow removal if it is not in that set

[sinful wave]

whenever they place a block

keep it in a

set

and

whenever they break

check if its in that set

and if it is allow

[glossy venture]

yeah thats what im saying

[sinful wave]

if it isnt cancel

ok cool

[flint coyote]

You store which blocks were placed and check if the broken block is stored in the block break event. You can also use that set to clean up the arena after the round ended, ya

[glossy venture]

and then to reset the arena

just remove all those blocks

i guess

or re-copy a schematic but that would require the admins to put schems of each arena too

[sinful wave]

schematic seems heavy on performance

especially if multiple matches are being started at once

since im just hosting this as a little project

i want it to be pr light

[echo granite]

Hello, I'm new to Guice and my plugin depends on Vault's Economy and Permission interfaces, so I created this module: https://pastebin.com/RZNFFqcy
I was wondering if that's considered an abuse since I run logic when the requested service is not installed on the server?

[harsh badge]

I don't think so

[echo granite]

are you replying to me?

[ivory sleet]

All depends on to what extent you wanna use guice, and how decoupled your system is going to be

[harsh badge]

no sorry

[blazing flare]

What's generally considered the better way to create inventories? I've seen the use of an inventory holder, or a map of player names and the inventory. Is there a reason to use one over the other?

[tardy delta]

wdym by a map of player names and the inventory

[echo granite]

I want to use a DI framework to get rid of maintaining like 1k constructors that have repeating dependencies(interface + only 1 implementation of it) - such as Economy and other services in the plugin

it's a pain in the ass to manually write constructors all the time

[ivory sleet]

Sounds like a design issue moreover

You should split your components up into smaller parts, use builders etc

[echo granite]

which I of course do

but it becomes a pain in the ass once the project is large enough

example:

[ivory sleet]

Cause if a component itself depends on a lot of other components arguably that component is relying on too much external

Ik what you mean

[echo granite]

https://pastebin.com/nvtZESCp

[tardy delta]

my inventory framework is designed as a Map<Inventory, InventoryGui> and the latter handles all clicks and optionally keeps track of all the viewers

[echo granite]

And those services would of course be used in many other places, but it's a pain to pass and maintain them every time

I'm starting to have more than 10 services, which SRP likes but I don't xd

[ivory sleet]

Thats the thing, right now it looks like you send your highest level components down to the lowest level ones in one go

[blazing flare]

A map, with player names as the keys, and the result of Bukkit.createInventory as the values

[tardy delta]

uh no idea why you would do that

Map::get would be a pain in the ass then anyways

[echo granite]

what do you mean?

[tardy delta]

you just want to keep track of the viewers ig?

hmm anyways is exposing iterators over collections considered good practice or are there better alternatives?

[echo granite]

It's a pain in the ass afterwards to convert the iterator to a collection again, so just expose defensive copies

public Set<User> getUsers()
{
    return new HashSet<>(this.users);
}```

it's also the recommended way by Effective Java

[echo basalt]

Collections.immutableCopy

type deal

[tardy delta]

hmm i started using iterators because i just needed to iterate over it

[echo basalt]

return an immutable copy

[echo granite]

why not a defensive copy? easier to use if needed

[echo basalt]

contains checks aren't suitable on iterators

[tardy delta]

if i dont need them

[echo basalt]

A defensive copy isn't explicit on whether it is a copy, or an actual mutable collection

[echo granite]

You should never return a mutable collection

[echo basalt]

the end user just assumes it's the original collection

[tardy delta]

Collections.unmodifiableX

[echo basalt]

^

[echo granite]

also that should be specified in the docs if it's mutable or not

[echo basalt]

your defensive copy is still mutable, but it modifies the copy instead of the original collection

[tardy delta]

imagine having docs lmao

[echo granite]

exactly, so the original list is defended

what's wrong with that?

it's just the code on the user's end that suddenly became less ugly

[echo basalt]

it doesn't

[echo granite]

I'm convinced now.

[echo basalt]

Set<Whatever> set = Collections.unmodifiableSet(original)

[tardy delta]

👀

[echo basalt]

it's still the same

[echo granite]

?

[echo granite]

This code goes in the method that returns the list

how is it the same?

[tardy delta]

and it backs the list you want to expose right?

[echo basalt]

the contents and order is the same

like

it's just a wrapper

[echo granite]

yes, but you need to do new HashSet<>(unmodifiableSet); if you want to use it

[echo basalt]

iirc

[tardy delta]

so whenever i add something to the orginal its wrapper is aware of it too

[echo granite]

which is ugly

[tardy delta]

hmm

just dont modify it lol

[ivory sleet]

The problem with returning an immutable copy is that it might be overlooked by the consumer, unless you annotate with @Unmodifiable or something

[tardy delta]

thats what i usually try to do but always forget lol

[echo basalt]

You can just make it return an immutableset

and still just use the Set<whatever>

so like

[ivory sleet]

Yes but that breaks the contract of the method to some extent

[echo basalt]

hmm

[ivory sleet]

Basically violating liskovs substitution principle

[echo granite]

Basically Collections#unmodifiableX methods should have never been added

[ivory sleet]

Myeah Idk any longer whats best tbh

I mean it has its usecases

But nowadays Set::copyOf and ::of as well as Map::of and ::copyOf exist

[tardy delta]

probably slower to create than a unmodifiable wrapper

[ivory sleet]

A bit myeah

[echo granite]

Can you explain what you meant regarding my question?

[tardy delta]

assuming you want to alter the collection it could be useful ig

[echo granite]

here

[ivory sleet]

Well command classes are low level

They are just some implementations of HOW your command interface works

And these services sound like quite high level

[echo granite]

I don't understand what's wrong?

[ivory sleet]

You should have one or more middle layers that reduce the amount of dependencies and simplify the contact between the high level ones and the low level ones

[alpine cairn]

Is it bad that I have no idea what y’all are talking about

[echo granite]

I can very easily get rid of CurseService and put its content in ChatService, but this is how you violate SRP and create a god object

[ivory sleet]

well if you go on to do it in an enterprise way, (which I assume you wanted to do since you use guice)

?

SRP means that one a class must only have one major reason to change

You don’t have to get rid of them

[echo granite]

huh?

it means the class only serves one purpose

[ivory sleet]

Yes thats the definition

Not really

[ivory sleet]

This is the formal definition

[echo granite]

okay, how would you refactor the code to reduce the amount of dependencies?

because it's a boilerplate nightmare once you have more than 5 in a class

[ivory sleet]

No not refactor, but instead create an internal api for your low level components

So they dont directly talk to the highest level ones

[echo granite]

can you maybe send a uml example? I really have no idea how to implement that(not technically but in my imagination)

[ivory sleet]

Myeah I can

I can create one when im on my pc

[tardy delta]

hehe typing on phone again

[quiet ice]

These methods are incredibly important when working with collections of larger size (or just high-throughput operations) or when the internal collection may not be modified and the returned collection must correspond to the internal collection. While sure you can do a desync-on-write type of thing but that'd be prone to hard-to-debug bugs

Plus the thread-safety aspect shouldn't be completely ignored when working with a desync-on-write/lazy-copy collection

[echo granite]

Well I do accept the efficiency claim, but I noticed that copying even 1 million elements from one list/set to another didn't take longer than 100ms

[tardy delta]

just wanted to say that thats two ticks but i dont think mc has collections with over a millions elements smh

[echo granite]

I once was bored so I decided to test that

lol

[quiet ice]

Differences compound. totalTime = singleTime * count. Inadvertently copying a million object long array once is no big deal. Copying it a few million times? No dice.

[echo granite]

I agree, but when in reality would you do millions of copies from one collection to another? wouldn't that be considered as a potential code smell?

[quiet ice]

Sometimes it is easier to just optimize the collection than to optimize the consumer

I know this sounds far-fetched so let's give an example:

• Claiming plugin A maps each block to a claim. This is stored in a glorified Map<Location, Claim>
• As you can imagine that map is going to have millions of entries
• Plugin B wishes to render all the claims to an image.
• Plugin B may under no circumstance change that map directly as it would break quite a lot of things

[harsh badge]

I'm gettgin package org.bukkit does not exist when I try to build my jar anyone have an idea?

[quiet ice]

If you were to copy the list even once you essentially retrieve something from the collection twice. You can optimize it by listening for changes and all that but in the end you'll have two different collections that have exactly the same contents.

However If you were to just provide an immutable collection that pass-throughs to the internal list it would go much quicker.

[quiet ice]

Maven, Eclipse JDT or Gradle?

[harsh badge]

i'm trying to use maven package

[quiet ice]

So you are using maven and no other build tool (such as Eclipse's export menu or whatever IntelliJ's pendant is)?

[harsh badge]

I'm going into intellij running maven package is there another way I should do this?

[eternal oxide]

using artifacts or the right hand maven menu?

[tardy delta]

same thing

i just added it as a run configuration

[harsh badge]

I tried looking into my gradle to see if it was missing anything but It works just fine unless I am trying to download it

[tardy delta]

wait are you using maven or gradle now

[harsh badge]

I'm now getting build errors as well java: package com.sk89q.worldedit does not exist

[remote swallow]

Maven or gradle though

[harsh badge]

Here is my gradle: https://paste.md-5.net/hejegawahi.cs

i started getting errors when I tried doing my mvn package

[tardy delta]

why combing maven with gradle 🤔

[harsh badge]

So I should delete my gradle file?

[tardy delta]

idk what you wanna use lol

[harsh badge]

I can delete my maven how would I do it with gradle to build to jar?

[fresh timber]

I have a method that takes in an inventory. I want to get the title of the inventory but I literally cannot seem to be able to do it. Does anyone know how I can get the title of this Inventory object?

[tardy delta]

idk how gradle works

[tardy delta]

InventoryView#getTitle right?

[remote swallow]

Ctrl crtl twice then type gradlew build

[fresh timber]

nah I tried that

[dusk flicker]

what have you tried, and what was the outcome

?jd

[undone axle]

Spigot: https://hub.spigotmc.org/javadocs/spigot
BungeeCord: https://ci.md-5.net/job/BungeeCord/ws/api/target/apidocs/index.html
BungeeCord Chat: https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/index.html

[tardy delta]

or was it InventoryHolder#getTitle

[quiet ice]

InventoryView

[fresh timber]

I tried inventory.getType().getname didnt work, I have tried.getname doesnt exist, I have tried.getViewers().get(0).getOpenInventory().getTitle()

[quiet ice]

InventoryHolder is roughly equivalent to player (exact implementor depends on the circumstances)

[fresh timber]

I have tried inventory.getview.gettitle

[tardy delta]

hmm thought that

[dusk flicker]

Can you upload that class to a paste?

?paste

[undone axle]

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

[harsh badge]

where to find the jar folder?

[echo basalt]

the true question

is why are you trying to get the title

[dusk flicker]

yeah

[echo basalt]

because there's no true reason

unless you're doing some extremely fancy stuff

but even then

[remote swallow]

Build/libs

[echo basalt]

there's probably a better way

[fresh timber]

so in my base64 I can put a title at the end and then take the title out when I use frombase64 because for some reason the method I got doesnt save the inventory name

[echo basalt]

mans tryna store a whole inv in base64

[fresh timber]

;-;

[tardy delta]

whats the reason youre saving an inv anyways

[fresh timber]

oh xd

[tardy delta]

i told him to do that instead of a db ;-;

[dusk flicker]

lol

[tardy delta]

i saved invs in base64 before too

[echo basalt]

base64 is nothing more than a representation of binary data

in a short form

[tardy delta]

shouldve done it in binary

[dusk flicker]

I feel like this convo is a perfect example of\

?xy

[undone axle]

http://xyproblem.info/

[echo basalt]

as we grab 1 long (8 bytes, or 64 bits) and represent it with a single character

and do some padding

[tardy delta]

🤡

[echo basalt]

like

the padding is just adding == at the end most of the cases

[fresh timber]

but seriously how can I get the title or save it in my base64 and btw I did this only cus I know the length of each title

[dusk flicker]

why do you need to save the title?

[fresh timber]

bruh ;-;

[fresh timber]

this

[dusk flicker]

again, do you NEED to save the inventory names? What inventories are you trying to save

[fresh timber]

yes they are inventory pages for my server and I save the inventory for each player when they close the inventory so I need to be able to know what inventory they have open with the title

[tardy delta]

at that point id just use gson or smth

[fresh timber]

hm oh wait

I could just set the title when they open inv

;-;

im kinda stupid sometimes

[dusk flicker]

Lol

thats why I was asking, if its a constant title with minor changes, you shouldent have to save it

[fresh timber]

oh wait I cant set the title ;-;

or no I could

[buoyant violet]

i saw a few websites but idk

i am learning java

on programmingbydoing

can you explain to me

a little better

[quiet ice]

compareTo is used to implement sorting

[fervent chasm]

How can I create heads using custom textures (using urls)?

[quiet ice]

It basically returns the "distance" of an object to another

[buoyant violet]

i need to do an assignement

https://programmingbydoing.com/a/alphabetical-order.html

[quiet ice]

For a.compareTo(b):

• 0 means a and b are at the same place
• < 0 means b is left to a (or the other way around depending on your representation)

• 0 means a is left to b (or see above comment)

[twin venture]

up

[buoyant violet]

geol

so how do i do that assignement

[quiet ice]

@buoyant violet If you still have no idea, see https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/String.html#compareTo(java.lang.String). If you STILL have no idea, you should go to sleep if you are tired or drunk or you should wait a few months until it clicks

[white dew]

Hi guys

[kindred valley]

Hello

[white dew]

I'm trying to implement a function to make the player able to climb walls, like a spider 🤔

[kindred valley]

Sure

[white dew]

my idea is to spawn invisible ladders in front of the player when a block is in front of them

not sure if thats possible

[kindred valley]

Make a custom ladder without texture

Pack it

Done

[white dew]

oooh

Idk how to do It, but thanks, now I know there is a way

I mean, creating custom blocks

[kindred valley]

Custom Models, you can customize an item, give it a data and then make a texture of which material that item has been done

So you will be able to make invisible ladder

[quiet ice]

You could spawn a vine block behind them I believe, but idk

[buoyant violet]

i dont know what it says

[white dew]

nice

[buoyant violet]

i am italian

[kindred valley]

But dont know how you can control player to touch a wall

Maybe use an api

[quiet ice]

If you do this for uni or comparable, you should seriously rethink your choice unless you are tired, drunk or otherwise limited mentally at the very moment

[kindred valley]

compareTo(); compares two

I mostly use them in BigDecimals

[quiet ice]

It's not going to get better. Though if this is the first time you are stumbling on something I guess you are still in the clear

[buoyant violet]

i need to create an alphabetic order

[echo basalt]

ehh that's annoying

you gotta spawn vines with a wall-detection algorithm

[buoyant violet]

yo this assignement is annoying asf

this.plugin.getServer().getScheduler().scheduleSyncDelayedTask((Plugin)this.plugin, () -> paramItem.remove(),

theres also a problem with paramitem

Also there is no need to cast (Plugin) this.plugin while using schedules

I think its because of your ide

I'm trying to make an event that happens when you right click a block

[undone axle]

The PlayerInteractEvent may be called once per hand. If you only want code to be executed once, you can check the result of https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerInteractEvent.html#getHand(), then decide functionality.

For example, only executing code if the main hand was used:

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
    if (event.getHand() != EquipmentSlot.HAND) { // * if the hand used is NOT the main hand:
        return; // do not progress past this point  |
    }
    // provide functionality
}

[chrome beacon]

The client won't be able to understand them

[glossy venture]

how would i get the UUID associated with a username without them necessarily having joined the server before? id assume something with mojang authlib

[sterile token]

java.lang.NoClassDefFoundError: com.mongodb.client.MongoClient i love mongo- hahaha

[civic wind]

Am i doing something wrong with PDC? Never used it before

[rotund ravine]

shade it

[sterile token]

Its being shade tho

[rotund ravine]

well apparently not

[sterile token]

Hmnn

[rotund ravine]

did u look it up before trying to use it?

[civic wind]

Yeah

[sterile token]

What you mean with that?

[civic wind]

oh you wasnt talking to me??

[rotund ravine]

i was not

[tardy delta]

no, might check the contents of the pdc entry tho

[civic wind]

how?

[tardy delta]

"my epic itemstack".equals(pdc.get(key, PersistentDataType.STRING)) or smth

dunno ifs its nullable

[sterile token]

I know that why i have to shade mongo

[civic wind]

ohh well it gets stuck at "T" the broadcast message

[rotund ravine]

@civic wind u gotta get the meta and set it after changing the pdc

[civic wind]

ohh

[rotund ravine]

https://puu.sh/JsAsf/d800f54099.png

[tardy delta]

and id store the namespacedkey as a constant on class level

forgot about that tbh

[civic wind]

That better?

Still stuck at the debug message hmm :/

[tardy delta]

dont create the itemstack every time

and clean up your warnings

[sterile token]

Mate i have been checking and im shading mongo library into the jar

[tardy delta]

whats your dependency

[sterile token]

mongo-java-driver

[sterile token]

And its telling me that its not founding the ConnectionString class but the lib is shaded correctly

[sterile token]

Yeah exactly the same

[tardy delta]

i didnt have to shade it lol

just the dependency

well leaving scope empty shades it automatically ig

[sterile token]

Yeah i know that

But didnt fix it tho

Also the most shity thing is that its working yesterday

😡

[civic wind]

What?

[vocal cloud]

If you've got a static never-changing item instantiate it once and then just give it to players

[mighty pier]

if i store a player in a database and in the plugin when the player joins and then load all players into the plugin on start

could it cause memory leaks or something like that

like if there are thousands of players

[vocal cloud]

As long as you map things right it won't

You can always populate it with test data

[mighty pier]

putting the user in an arraylist of users

[vocal cloud]

You can also lazy-load the data depending on what you need

[mighty pier]

banning and changing other stats of the player

maybe

when a player does a command

and its not loaded in the plugin

it goes through the database to find the player

but i think that would be worse

[tardy delta]

dont load all players lol

[vocal cloud]

Again, depending on what you need you should lazy load your data

[mighty pier]

user*

wym by lazy loading

[tardy delta]

only load it when needed

[vocal cloud]

Lazy loading is the practice of delaying load or initialization of resources or objects until they're actually needed to improve performance and save system resources.

[tardy delta]

get ninjad

[vocal cloud]

[civic wind]

Yeah i'm not sure how to do that?

[vocal cloud]

When a player joins you give them the good stuff

[mighty pier]

yes but im using sql and if it has to go through thousands of players its worse

becuase it has to go through all the players in the sql file

[civic wind]

It's command based, idk what you mean

[vocal cloud]

wrong person lol

Just make a static final variable and assign it the function call of getItem();

[mighty pier]

    private final UUID uuid;
    public UUID getUuid() {
        return uuid;
    }
    public Player getPlayer() {
        return Bukkit.getPlayer(uuid);
    }

    public User(UUID uuid) {
        this.uuid = uuid;
    }
}``` thats the class thats gonna be stored in a list

[vocal cloud]

At the worst your request would take 100ms. That assumes your db isn't local. Just async load it when the player joins. By the time they've logged in the data should be there.

[mighty pier]

im gonna add more variables later

[civic wind]

This to me or? I'm confused lol

[mighty pier]

alr

but also

could i keep a different thread

open

[vocal cloud]

No reason to.

[mighty pier]

there is

i have boxes in my other plugin

[vocal cloud]

Execute a scheduled service if you need to.

[mighty pier]

and it has to loop through a bunch of blocks

and there could be a lot of arenas

and if i just put runtaskasync

it would run out of cores

so no async

[vocal cloud]

Why would it run out of cores?

[mighty pier]

a lot of arenas

if i put runtaskasync in every arena

[vocal cloud]

Okay? That's not how scheduled threads work

[mighty pier]

ok

thanks for knowledgfe points

[vocal cloud]

You create a scheduledexecuterservice and make it 1 thread and you can throw everything into it

Then, it will process 1 by 1

if you don't want a delay then executorService

[mighty pier]

send scheduledexecuterservice tutorial

[vocal cloud]

its the same as bukkits

[mighty pier]

https://github.com/frandma/Box/blob/master/src/main/java/me/frandma/box/arena/Arena.java

do i just put runtaskasync on the bukkit runnable?

[tardy delta]

an Arena shouldnt be aware of its surrounding database

[mighty pier]

why not

its cleaner uwu

[tardy delta]

it should be the other way around

[mighty pier]

but then i have to do arenamanager.createarena

thats no fun

[mighty pier]

why

[tardy delta]

i just told you, an arena shouldnt be aware of the database

I'm trying to get the selection of a player using WorldEdit API

Why, even creating a selection with the wand, I still get the EmptyClipboardException?

[serene sigil]

so with this i can open a book gui?

[mighty pier]

just google it

nms books spigot

or sometrhing

or use protocollib

[serene sigil]

where can i download nms?

@mighty pier

[mighty pier]

replace spigot-api in the pom.xml to spigot

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[serene sigil]

what exactly does this mean?

sry im very new to spigot

[remote swallow]

run bt

change that in ur pom.xml

[serene sigil]

what is build tools?

[remote swallow]

the thing that builds spigot and gives you full access to allof spigot

[serene sigil]

what do i have to put inside?

[remote swallow]

change the spigot-api to just spigot

after running buildtools

[serene sigil]

i dont have it

cuz i just converted to maven

[remote swallow]

add the dep then

[serene sigil]

ye but what is the dep??

im currently using the shaded.jar

[hazy parrot]

That doesn't looks like maven

[serene sigil]

ik

[serene sigil]

.

why aint this right?

[remote swallow]

remove the -api

[sterile token]

Fourten

I have find what is happening!!

After 30m checking code and restarting, etc i realize i accidentally uploaded the not shaded jar + all time restarting uploaded the shaded one, but never realize the not shaded was already uploaded

Im defintly a 🤡

[twin venture]

Hello anyone using UltraSkywars [ i know its abandoned and its open source ]
iam trying to do a check ,
[Check if the chest is opned , is one of the middle Chests] ..
there is few things in the api for the chests , but i tried few things and didn't work

the code keep running even if i open a island chest

it should only run if its a center chest

[serene sigil]

not found

[tardy delta]

and do mvn reload

[twin venture]

i was thinking maybe i can check if the player location is near the middle chest [ center chest] , if so the continue the code :

ideas please?

[quiet ice]

You are better off getting someone else to do it for you, I guess

LocatioN#distanceSquared() is faster than LocatioN#distance()

[serene sigil]

?

oh ye i did

[rough drift]

ItemStack item = new ItemStack(Material.MAP, 1);
MapView view = Bukkit.createMap(itemFrame.getWorld());
for (MapRenderer renderer : view.getRenderers()) {
    view.removeRenderer(renderer);
}

TestMapRenderer renderer = new TestMapRenderer();
view.addRenderer(renderer);

MapMeta mapMeta = (MapMeta) item.getItemMeta();
mapMeta.setMapView(view);
item.setItemMeta(mapMeta);

crashes with

java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_19_R1.inventory.CraftMetaItem cannot be cast to class org.bukkit.inventory.meta.MapMeta (org.bukkit.craftbukkit.v1_19_R1.inventory.CraftMetaItem and org.bukkit.inventory.meta.MapMeta are in unnamed module of loader java.net.URLClassLoader @45fe3ee3)

The item meta is a map meta no?

[tardy delta]

isnt it FILLED_MAP

[remote swallow]

have you ran buildtools

[rough drift]

I used it

that improved the result

[twin venture]

is it the same?

[serene sigil]

how do u do that?

[twin venture]

what's the diffrence i mean why its faster

[remote swallow]

[remote swallow]

download the jar and git then run the correct command

https://gitforwindows.org
https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar.

[hazy parrot]

distance is just Math.sqrt(distanceSquared(loc))

[remote swallow]

in a new gitbash in a new folder with buildtools, java -jar BuildTools.jar --rev VERSION

[serene sigil]

is there a tut on how to do that?

[hazy parrot]

https://www.spigotmc.org/wiki/buildtools/

[remote swallow]

download git, download the jar

cerate a new folder

drag the buildtools jar into that folder

right click, click open gitbash here

[hazy parrot]

you dont even need git

[remote swallow]

type java -jar BuildTools.jar --rev 1.major.minor then press enter

[remote swallow]

thought you did though

[eternal oxide]

BT downloads it's own Git/maven

[remote swallow]

you learn something new everyday

[sterile token]

Indeed

[rough drift]

So I ran into an issue: Using a custom map renderer it seems as if when another player block-picks the map I can't see it anymore unless I also select it

why's that?

Also, it seems as if something is still sending a ton of map packets, even though I removed all renderers (including mine)

[rough drift]

To update the map I send ClientboundMapItemDataPacket (I am not using a map renderer per se, I call it that), and if you're wondering why I am using packets: In my specific case it's more performant to do so than to use the spigot API, that's it really lol

[ashen lynx]

Hi! How can I block sideways moving of a player who riding a horse?

[echo basalt]

don't do custom images like this pls

it's too fuckin slow

[twin venture]

Hello , is there a better way i can imporve this working code?

its working correctly , but i want to improve it , as i see allot of if statments , and for loops

[round finch]

[echo basalt]

Let's see...

First things first

Ctrl + Alt + L

It should restructure it

a flaw I notice is that you're doing return; inside for loops

which completely returns the method, instead of skipping the iteration
