[civic spoke]

or stringify it some other way

[icy beacon]

sometimes the ide shows false positives, manually make sure that you avert all the edge cases

[civic spoke]

json was just the first thing that came to mind

[red sedge]

huh- why would you do that

[civic spoke]

?

[icy beacon]

well

[red sedge]

why would you broadcast a message no one will ever be able to see

[icy beacon]

broadcast message sends it to all the players afaik

^

do Bukkit.getLogger().info()

[untold patio]

Hmm

[hazy parrot]

?pdc

[undone axle]

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

[untold patio]

I tried with object output stream but didn't work

[civic spoke]

onEnable happens when /reload happens right??

[jovial grotto]

Also how would I save a hash map? I use a hashmap to keep track of variables etc and the plugin would lose its purpose if the server crashed/restarted

[red sedge]

iirc you can also just do getLogger() in the main class

[untold patio]

Ok, imma take a look

[icy beacon]

true

[icy beacon]

i think there's an onreload method but don't quote me on that

one sec

[red sedge]

people still reload shit?

[civic spoke]

i do at least

[red sedge]

i thought we left that in 2016

[icy beacon]

well you shouldn't

it's a bad practice

if you do, make a plugin command

like /myplugin reload

and handle your reload there as you wish

[red sedge]

its not necessary bad practise i wouldnt say

if you want to support that command

[civic spoke]

:/

ok

[icy beacon]

from what i know, /reload cold stops and starts all the plugins

[civic spoke]

thanks for your help btw!

[red sedge]

go for it, its unnecessary effort cos most plugins wont do it

[icy beacon]

yeah, just the /reload is bad

a lot of plugins will break

[kind hatch]

I think the consensus is that /reload is fine for development purposes, but to never use it in production.

[icy beacon]

^

[red sedge]

i dont think /reload is bad if youre willing to support it

[icy beacon]

i do use it in dev because i handled the edge cases sometimes

[red sedge]

the reason its bad is because most plugins dont support it

[icy beacon]

well, since people should not reload, it's pointless to just support it

better off creating a plugin command to only reload itself

[red sedge]

^

[icy beacon]

like the reload idea is good

but spigot can't read the plugin's mind

to know what will break and what won't

[jovial grotto]

How can I save a hashmap when the server stops the plugin (Bascially when onDisable is called I want to save a hashmap, and then when onEnable is called I want to load a hashmap)

[red sedge]

uh

[icy beacon]

?pdc or file storage

[undone axle]

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

[red sedge]

load it to a file

[jovial grotto]

cheers

[red sedge]

supprting /reload is a bad idea because its far too much effort to get perfect and it most likely wont be used at all since most plugins will break if you do /reload

[icy beacon]

yeah just make your own /plug reload

[red sedge]

oh and also most likely you dont need to reload the entire plugin

[jovial grotto]

I dont think that is what I am looking for

[red sedge]

try file storage

yeet the hashmap into a file

[icy beacon]

it kinda is, you can bind a pdc to a chunk i think

[red sedge]

and then load it on start

[icy beacon]

https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

files are cool but bad users might just delete them

[red sedge]

but just wondering, why do you want to save a hashmap?

[icy beacon]

so it's dangerous

[red sedge]

yeah but i think you should give that option to server owners

[icy beacon]

what

[red sedge]

cos saving a hashmap seems kind of.. weird

[icy beacon]

if the dev aims to persist data between restarts why would you break it

[jovial grotto]

My plugin uses a hashmap to store which users need to have a gui shown to them (It is a Freeze plugin), but if the server restarts than ofc the hashmap is wiped and it is pointless. Idk why I feel this is necessary but yeah? If it crashes that is just my worry

[red sedge]

well if you aim to persist data between restarts

that data must be increasing somewhere

[icy beacon]

pdc

[red sedge]

so youshould give the option to server owners to delete that data

[icy beacon]

yeah... it's not exactly how it works i don't think lmao

if the plugin needs that data why would you delete it

like

[red sedge]

i see

oka

one option you have is to store that in the players pdc itself

[icy beacon]

imagine i'm developing a plugin and i need to save some data for the plugin to be launched properly the next time

and some owner deletes it because they have the option to

that would be kinda

uh

not cool

[jovial grotto]

It isn't needed though

[icy beacon]

granted, that's a design flaw, but my point is the same

[icy beacon]

then of course do not use a file

[red sedge]

i would say youre a bad developer

[icy beacon]

^

[jovial grotto]

I guess it isn't the end of the world

[red sedge]

chopkeys

[jovial grotto]

If they lose it

[red sedge]

you can use the players pdc

or you can use files

which would be a better idea

[icy beacon]

then don't save it at all?

[jovial grotto]

Yeah it was just a QoL thing at the end of the day

[red sedge]

since it will allow the server owner to get rid of the plugin easier without having left over data

just use a file

[jovial grotto]

ye

[icy beacon]

the pdc values are binded to plugins, so it won't interfere if the plugin is deleted, and i imagine that saving a couple itemstacks or whatever to pdc wouldn't hurt the storage too much

[red sedge]

its binded to the plugin?

[icy beacon]

yeah pdc requires namespacedkeys

and they require plugins

[red sedge]

isnt it binded to players nbt file?

[icy beacon]

you can use NamespacedKey().minecraft() but it's a bad idea

[red sedge]

well yeah and so does it for items

[icy beacon]

i mean that the address of the pdc is binded to the plugin

it will remain but it won't be used

[red sedge]

but the nbt persists even if you remove the plugin

[icy beacon]

if the plugin is deleted

[red sedge]

yeah...

you probably shouldnt do that

[icy beacon]

is it.. bad?

[red sedge]

kind of

[icy beacon]

in what way

[red sedge]

youre practically leaving trash behind

[icy beacon]

a couple hundred bytes

yeah fuck it use an h2 db then

to store the hashmap

[red sedge]

or..

[icy beacon]

not easy to edit and easy to get rid of

or make a mysql database

[red sedge]

why would you not want it to be editable?

anyways

[icy beacon]

easy to edit if you know what you are doing, easy to get rid of, no trash left behind

[icy beacon]

because if it were to be editable, there would be no need to save it separately from just saving player data

[red sedge]

the easiest way i can think of (if you dont wanna mess w databases) is having a yaml file

[icy beacon]

bruh

[red sedge]

mate, theyre making a fucking freeze plugin

i doubt they have any other data to store

[winged anvil]

lmfao

beef

[icy beacon]

how is this beef

[red sedge]

because we have different opinions and are discussing

such a heated fight innit

[icy beacon]

yeah i'm stressed and sweating

[winged anvil]

ong

[jovial grotto]

Yeah it is literally a persons UUID and then a Boolean

[red sedge]

yh

just yeet it into a yaml file

[icy beacon]

if you are british i won't talk to you anymore, but anyways, if this is a talk of saving player data, you can just save it in pdc and not worry ever. what the plugin can do to optimize it is delete the pdc data after it's been used, and then the only case when the data is left unused is when the plugin is deleted and somebody is frozen

[winged anvil]

see thats major beef

[icy beacon]

k

[red sedge]

im heart broken

[icy beacon]

are you... bri'ish?

[red sedge]

who knows

[winged anvil]

nah i agree with lol for plugins you distribute, use file storage, not pdc for the reasons they already stated

[icy beacon]

lord have mercy

[icy beacon]

if you are gonna store large amounts of data, sure

[red sedge]

i dont really like pdc anyways

[icy beacon]

oh that's a convincing argument

have a nice day

[red sedge]

no its an opinion

[winged anvil]

the argument was, devs would leave behind data if a plugin was deleted. seems good enough for me

[icy beacon]

i mean, yeah, you are right, the data will be left behind, but why is it a problem if the amount of data is insignificant

[red sedge]

because it shouldnt be there

if i uninstall something, i expect it to be gone

[icy beacon]

the only way you can access it is if you hard view the nbt files, and if it's basically inaccessible, it's basically gone, no?

[red sedge]

that makes it worse

it makes it harder to get rid of

[icy beacon]

but if you install the plugin again, it can reuse the data, which is good

what if you deleted the plugin by mistake with some worthy data, and all of it was stored in files?

[red sedge]

but you want to backup the data in the plugin

you cant

[icy beacon]

many people don't do that

[red sedge]

many people do actually

[icy beacon]

i know a lot of server maintainers who never did backups until i advised them to

it's kinda fucked up

[red sedge]

who the fuck deletes the plugin AND its folder from the server folder and the trash bin by accident

[icy beacon]

trash bin?????

[red sedge]

idfk everyone calls it smth different

[icy beacon]

i thought literally everyone used ftp and a vds and not a local server to host a minecraft server

what

if you've found a way to manipulate the vds' trash bin with ftp and you find it reasonable, you've achieved a higher plane of existence

[red sedge]

sdfgiefjgkl

anyways i dont think ive seen anyone accidentally delete the plugin folder

[icy beacon]

people are clumsy

[red sedge]

ah yes

[icy beacon]

xd

[red sedge]

"so my hand fell and i selected the plugin folder, went across the screen clicked the delete button, and then my mouse also went to the confirm button and pressed it"

[echo basalt]

[icy beacon]

haven't seen a confirm button in ages, but btw, a while ago i used an explorer that, when alphabetically sorting, would mix files and folders together, so it was really easy to just select them together lmao

most explorers and ftp clients now separate them

but it's kinda bad

that it was possible

[red sedge]

at that point you probably shouldnt run a server

juss sayin

leave server running to people above 8

[icy beacon]

i mean, on the server i'm developing, all the plugins are private so i micromanage every piece of shit

have you been to r/admincraft? people do the wildest shit there

[icy beacon]

i wouldn't be surprised if somebody reported this some time ago

[red sedge]

oh if youre not gonna publish it sure use pdc however you want

[icy beacon]

i use mysql for convenience, but i used to use pdc before, because it was easy to manage everything

plugin files can be broken in a matter of seconds, but i haven't really seen people going into playerdata and messing with it

anyway

guess it's up to chopkeys anyway

[red sedge]

oh

fuck i forgot this was about chopkeys

[icy beacon]

xD

hottest beef ever

btw do you have experience with kotlin?

[red sedge]

nah

why

[icy beacon]

been looking for somebody to help with #1043942626472230923 for a while

[red sedge]

the only time im fine w pdc is with custom items

[red sedge]

o sorry

[quiet ice]

So if that actually was what you wanted we got an issue

[winged anvil]

major beef

[civic wind]

Whats wrong with being british?

[undone kernel]

when was meta.addItemFlags added

[atomic swift]

new AttributeModifier(String name, double amount, Operation operation) is the name just anything i want

[warm mica]

It already existed with 1.8

[undone kernel]

damn is there a way to hide enchantments in 1.5

[fresh timber]

I am setting a format with this line:

event.setFormat("§8[§4§lOWNER§8] §f%s: %s");

how can I allow them to use color codes in this? I tried to use:

event.setFormat(ChatColor.translateAlternateColorCodes('&', "§8[§4§lOWNER§8] §f%s: %s"))

but it did not seem to work. How do I allow color codes with & for this?

[quiet ice]

that is a seriously old version to use bukkit with

[undone kernel]

i got a piece of code for that

    public String colorize(String msg) {
        return ChatColor.translateAlternateColorCodes('&', msg);
    }```

[undone kernel]

eaglecraft plugin

[quiet ice]

And quite random too

[undone kernel]

it works like this

[fresh timber]

uh ok ill try this do I just use colorize("§8[§4§lOWNER§8] §f%s: %s")?

[warm mica]

dear lord

please stop with what you are doing immediately

[undone kernel]

but with the & signs

[undone kernel]

what's wrong with this

[fresh timber]

well that msg will contain & signs cus the 2nd %s is the msg

this should not help

its the same thing

[quiet ice]

You must set the message, not the format

[undone kernel]

what's the %s for anyway

[fresh timber]

;-;

[quiet ice]

Calling event.setFormat(ChatColor.translateAlternateColorCodes('&', "§8[§4§lOWNER§8] §f%s: %s")) is identically to calliung

String var10001 = ChatColor.translateAlternateColorCodes('&', "§8[§4§lOWNER§8] §f%s: %s");
event.setFormat(var10001);

which is identical to calling

String var10001 = "§8[§4§lOWNER§8] §f%s: %s";
event.setFormat(var10001);

which is identical to calling

event.setFormat("§8[§4§lOWNER§8] §f%s: %s");

[quiet ice]

String#format

[undone kernel]

ah

[fresh timber]

in a chat format, %s first time is the players name and %s second time is name

[quiet ice]

You seem to confuse .setFormat with .setMessage

[undone kernel]

damn i do my chat things completely differently and probably wrong ;- ;

[quiet ice]

Oh, so many people do things completely wrong in bukkit world

[fresh timber]

but, how do I allow ppl to use chat colors

because it does not work to use &c or anything wiht translatealternatecolorcodes or anything else ive tried

[quiet ice]

?jd sigh

[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

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/AsyncPlayerChatEvent.html#setMessage(java.lang.String)

[fresh timber]

I hate this website

doesnt tell me anything

[undone kernel]

this is probably more wrong than anything tho

[quiet ice]

So basically evt.setMessage(ChatColor.translateAlternateColorcodes('&', evt.getMessage()))

[atomic swift]

new AttributeModifier(String name, double amount, Operation operation) is the name just anything i want

[red sedge]

how would i go about making custom blocks with directions?

like for directionless ones i can use noteblocks

[quiet ice]

https://helpch.at/docs/1.5/org/bukkit/event/player/PlayerChatEvent.html#setFormat(java.lang.String) yeah, more than wrong

[red sedge]

but i dont think using noteblocks for ones that have a direction would be a good idea since therres only about 1000~ block states for noteblocks

[undone kernel]

if it works it works

[red sedge]

and each block would require 6 states just to function

[civic spoke]

how might you save/load a location to/from a string?

like i can do the x, y, z components easily but for the constructor how do i have the world argument

[quiet ice]

You can leave it null if needed

I believe

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Location.html#<init>(org.bukkit.World,double,double,double) yep, Nullable

[quiet ice]

I prefer UUIDs

[round finch]

well you get a double from a String x,y,z

[civic spoke]

yeah but what does that do

[quiet ice]

Try it out and find out. Probably will break everything instantly though as it is meant for semi-loaded locations

[civic spoke]

what even is a World?? is it for the different dimensions?

[quiet ice]

Yeah

[red sedge]

any ideas?

[quiet ice]

Can't you make up new blockstates these days?

[red sedge]

dont think so

[round finch]

yes

[red sedge]

oh what?

[civic spoke]

16 instruments * 25 pitches = 400 states

[round finch]

i did a spinning sign once

[wary topaz]

https://paste.md-5.net/ulojuzotet.java
Method invocation 'getDataFolder' will produce 'NullPointerException' (I dont know why it's erroring)

Line 20.

[quiet ice]

Alternatively, https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Server.html#getWorld(java.util.UUID) combined with https://hub.spigotmc.org/javadocs/spigot/org/bukkit/generator/WorldInfo.html#getUID()

[red sedge]

• 2 activated or not

[civic spoke]

oh

[red sedge]

yeah but thats not a new block state is it

youre overriding another block state

[round finch]

get the blockstate
change the blockstate

[quiet ice]

plugin IS null

[wary topaz]

?

Why?

[quiet ice]

it shouldn't even compile to be exact

[red sedge]

you cant do that tho..

[quiet ice]

You never assign anything to plugin and that assignment is run before the constructor

[red sedge]

it needs to be a valid block state form minecrafts existing ones

[wary topaz]

oh

alr

[round finch]

yeah it is needs to be existing block ofc

[quiet ice]

Protip: Use JavaPlugin#getProvidingPlugin

[red sedge]

ye so im trying to find another block that has. abunch of blockstates that is not noteblock

[quiet ice]

Mushrooms, but those are limited too

[red sedge]

cant i just like change the nbt of the placed noteblock to a custom instrument like idk "hello"

imma try-

[quiet ice]

But can't you define more blocks through datapacks or does the client need to be aware of that too (i.e. resource packs aren't enough?)

[round finch]

pdc?

[red sedge]

custom models dont work w pdc

bedrock has custom blockstates :c

[quiet ice]

If PDC is the concern, just use chunk pdc as long as it isn't absurd amounts of data you need to store

[red sedge]

no its not the isuse

the custom models are

[atomic swift]

new AttributeModifier(String name, double amount, Operation operation) is the name just anything i want bc theres nothing in the javadoc

[quiet ice]

Most likely

[round finch]

getCustomModelData?

[quiet ice]

that is for itemstacks

[round finch]

1 sec lemme search

[atomic swift]

ItemMeta meta = item.getItemMeta();
meta.getCustomModelData();

[quiet ice]

-.-

They want to apply it on blocks

[round finch]

ye

[atomic swift]

ItemMeta meta = ItemStack#getItemMeta();
meta.setCustomModelData(Integer);
ItemStack#setItemMeta(meta);

[red sedge]

gosh why does java have to have weird ass blockstate rules

[quiet ice]

that is mc

[red sedge]

no but bedrock can just say "lets add custom_block_model_5843" and it does

[quiet ice]

Ah java edition you mean

[red sedge]

yas

i hate this

[round finch]

sadge

nothing i see

[red sedge]

redstone wire has a lot of statess

but since its not a full block and its insta brak

cant use it

alr im just gonna make a script for it

[sterile token]

Hi, how is called the thing thatis use by faction plugins to display the regions/areas corners? I try to look for them via Map view but its nothing to do with that i expect

[undone kernel]

why doesn't this work

[chrome beacon]

Looks like that constructor doesn't exist

[sterile token]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[chrome beacon]

My guess is that your version doesn't have that one

[undone kernel]

i'm pretty sure I have everything that it'

s asking for

[chrome beacon]

What version of spigot are you depending on

[sterile token]

Your parameters are one the one expected on the method

[undone kernel]

1.5.2

[quiet ice]

UUID.randomUUID().toString()

[sterile token]

LOL

[chrome beacon]

Yeah that constructor doesn't exist

Also 1.5.2 💀

[sterile token]

1.5.2 is dinosaur

[undone kernel]

i mean clearly it does

it shows up and everything

[chrome beacon]

It doesn't

[sterile token]

Also why legacy versions?

[chrome beacon]

Not in 1.5.2

[quiet ice]

Does anyone know some decent (J8-style) javadoc page for legacy versions?

[sterile token]

Spigot support only +1.16 up

[undone kernel]

and it works without the Equipment slot thing

[chrome beacon]

Yeah

The equipment slot param is new

[sterile token]

I think he is using 1.15.2 but said 1.5.2

[quiet ice]

Does the attributeModifier class event exist in 1.5.2?

[quiet ice]

Oh he def. knows what to use

[undone kernel]

for me somehow it does

[undone kernel]

no i'm literally using 1.5.2

[quiet ice]

Strange, https://helpch.at/docs/1.5/ does not mention it (nor it's package) existing

Probably has something to do with 1.5 vs 1.5.2. Ugh

[sterile token]

I mean spigot must ban 1.16 under because its really annoying to help them

[undone kernel]

so I can't use the Equipment slot thing

[chrome beacon]

No

As I've said it doesn't exist

[undone kernel]

damn

so everything else exists except the one thing that is important

[undone kernel]

it's in this image

[quiet ice]

Yeah, the screenshot explains enough

[undone kernel]

yes it does

google it

[quiet ice]

(For reference eaglercraft is EoL though as fra s I know)

[sterile token]

totally agree

[quiet ice]

Or rather said the repos were meant to be taken down

[undone kernel]

I got the item and everything

but I can't add an attribute

[red sedge]

thats sad..

really hoped there would be more block states

[undone kernel]

bruh I just discovered that the AttributeModifier is a thing but YOU CAN'T ACTULLY USE IT

[red sedge]

most of them aint even solid blocks

i mean

i guess i could always go with the good old armor stand way

[quiet ice]

What exactly are you using anyways?

[civic spoke]

how do you do file io? i tried to read/write to a file but it's not finding it despite it being in the same directory

[quiet ice]

Are you sure that it is in the same dir?

[undone kernel]

wdym

[quiet ice]

i.e. did you do any typos or anything?

[quiet ice]

Like what artifact are you binding into?

[civic spoke]

it's in the plugin directory

[quiet ice]

aha, cb

[undone kernel]

also how tf do I use this

[quiet ice]

What exactly are the two paths?

[undone kernel]

    @EventHandler
    public void onArmorEquip(ArmorEquipEvent e) {
        Player p = e.getPlayer();
        if (e.getOldArmorPiece().getItemMeta().equals(itemManager.ultimateHelmet().getItemMeta())) {
            p.setMaxHealth(p.getMaxHealth()+5);
        }

    }```
like I have this code

[civic spoke]

<root server>/plugins/MninPlugin.jar and <root server>/plugins/mnin_data.json

[undone kernel]

nvm it just decided to work for some reason

nvm again it broke

[quiet ice]

goes without explaination that those are two different paths

[civic spoke]

yes because they are the plugin and the file it is trying to access

[quiet ice]

What is the READ path and what is the WRITE path?

[pine island]

Havent used spigot in a million years and my 1.8(i know please dont shout at me) import is not working and yes i have my repos imported:

they are both <root server>/plugins/mnin_data.json

[quiet ice]

ugh, it is nearly impossible to obtain any decent javadocs for legacy CB

[quiet ice]

then what is the exception?

[undone kernel]

why are you tryna find it anyway

[mighty pier]

is there anything else i could do instead of ```java
if (something) {
if (othersomething) {

}else {

}
}else{

}```?

[civic spoke]

FileNotFoundException arghghghg

based on the logs

[quiet ice]

Okay, funny

[pine island]

i eman if ur nesting if loops u can use if(!xyz) { }

[quiet ice]

I meant stacktrace when I said "exception"

[pine island]

which makes it easier to read

[undone kernel]

https://jd.andross.fr/1.5/

[quiet ice]

That also is bukkit, not CB

[undone kernel]

oh wait I found the class for the attribute thing

[quiet ice]

Unless there really is no "AtrributeModifier" class, which would mean that you have some random atrifact adding that class on the compile classpath even though you do not want to

[15:51:29 ERROR]: Error occurred while disabling MninPlugin v1.0 (Is it up to date?)
java.lang.NoClassDefFoundError: org/json/JSONObject
    at mnin.DataSaver.saveData(DataSaver.java:29) ~[?:?]
    at mnin.MninPlugin.onDisable(MninPlugin.java:25) ~[?:?]
``` i am in pain

[quiet ice]

No, not without doing something like if (cond1 && cond2) {} else if (cond1) {} else {}

[undone kernel]

check the paste thing

[quiet ice]

that is WAI, nothing you can do about that

[civic spoke]

what's WAI?

[quiet ice]

That is unless you want to play the classloader

Working as intended

[round finch]

is this real? if(!x y z) { }

[civic spoke]

???? how do i fix it then?

[undone kernel]

i don't think I have a random artifact adding it but i in fact don't see the actual class even though it shows up

[quiet ice]

As I said, play the classloader - that is load all classes that you need in your onDisable block before running onDisable

[civic spoke]

but i am loading them

i'm importing them

[quiet ice]

Loading != importing

[civic spoke]

package mnin;
import org.bukkit.plugin.java.JavaPlugin;
import java.io.*;
import java.util.logging.Level;
import org.bukkit.command.*;

public class MninPlugin extends JavaPlugin {
    CommandRunner runner = CommandRunner.getInstance();
    DataSaver dataSaver = DataSaver.getInstance();
    
    // Fired when plugin is first enabled
    @Override
    public void onEnable() {
        try {
            dataSaver.loadData();
        } catch (FileNotFoundException e) {
            getLogger().log(Level.WARNING, "Save data file not found (" + dataSaver.getSaveFilename() + ")");
        }
    }
    
    // Fired when plugin is disabled
    @Override
    public void onDisable() {
        try {
            dataSaver.saveData();
        } catch (IOException e) {
            getLogger().log(Level.SEVERE, "Could not write to save data file");
        }
    }
    
    // Fired on command
    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        return runner.runCommand(sender, command, label, args);
    }
}

[quiet ice]

Java will load classes as late as possible

But because spigot is spigot it will pseudo-close the classloader and thus refuse to load the classes when the plugin is disabled (which is the case when running onDisable)

It's really annoying behaviour, but unfortunately intended

(the classes being loaded/initialized late is very useful behaviour though)

DataSaver.java (sorry for the text wall)

saveData is where the error occurs

because it can't find JSONObject

[hard ether]

Is there a better method to use for broadcasting than broadcastMessage()?

[quiet ice]

Do JSONObject.class.toString(); in your onEnable() to fix it

Then do the same for any other class that will throw similar exceptions

It sounds stupid, but it works

[civic spoke]

will it still work if i put that inside DataSaver's constructor? (it's called when MninPlugin is initialized)

[quiet ice]

okay hold on, that class should be loaded when constructing that class

Did you shade that class?

[civic spoke]

?

[tulip nimbus]

Better in what sense? What’s missing from broadcastMessage?

[quiet ice]

And what other stacktraces do you see? NoClassDefFoundException is usually not alone

[quiet ice]

As in did you include that class in your jar. Or in layman's terms: Gib jar

[civic spoke]

yes

it's in src/mnin which is included since MninPlugin which is also in there is included

[quiet ice]

Yeah, I really want to see that jar now

[civic spoke]

what like the file?

[quiet ice]

I guess you accidentally jar-in-jar'd (JIJ) org.json:json as I doubt you included the org.json:json source code in your plugin's source code folder

[quiet ice]

the compiled plugin jar

[civic spoke]

i did

should i just extract that jar?

[quiet ice]

Really, give me the compiled jar, I can only do a guessing game without that jar

[civic spoke]

sent

[quiet ice]

(alternative give a screenshot of the project folder, but what is the fun in that - plus it wouldn't affirm nor deny my current suspicion of accidental JIJ-ing)

okay, thanks to you using eclipse I already know how the project folder looks like

[civic spoke]

nice

[quiet ice]

I hate to break it to you, but you got to decide: Maven or gradle?

(There is also Ant and other fringe build tools such as slbrachyura, but we shouldn't go that route, should we?)

[civic spoke]

i honestly don't know; i'm just using export > jar > select the stuff in my project to export lmao

[quiet ice]

Just that that does not work in your case

Unless you copy over the contents of org.json:json's source code to your source folder or the content's org.json:json's compiled .class files to your resource folder

which uhm, would be cursed AF

[civic spoke]

you know what, idc about cursed. i might just do that tbh

[pure cloud]

You'll thank yourself if you learn maven or gradle 🙂

[hard ether]

maven >

[quiet ice]

For eclipse maven is better. Gradle's eclipse integration leaves much to be desired

(I know, technically it is an eclipse plugin providing gradle support, but whatever)

[pure cloud]

I'm surprised there are still people using Eclipse tbh

It's what I started off using but I quickly moved to IntelliJ

[floral kindle]

Does anyone know an alternative way to this function that is not working anymore?

entity.damage(1, player);

[quiet ice]

I wouldn't be able to make the switch - especially not nowadays as most of my stack would rely on IJ's eclipse project support

[pure cloud]

Anyway, either Maven or Gradle will make it much easier for you to build your software both now and in the future. I think Maven is probably a bit more well-known/supported, especially in the MC world. Afaik there's nothing you'd want to do that Maven can't do

[pure cloud]

it looks like that function still exists/works: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Damageable.html#damage(double,org.bukkit.entity.Entity)

Why do you think it doesn't?

[civic spoke]

yeah the cursed "solution" wasn't working; i'll switch to maven

[quiet ice]

it definitely does, you need to unzip the jar first though

[floral kindle]

I mean it doesn't work anymore!

[pure cloud]

What doesn't work about it?

[quiet ice]

Yeah it should still work

[pure cloud]

Are there errors in the console? Does it work on a server without any other plugins?

[civic spoke]

i tried but i couldn't figure out how to proceed so i reverted it

as for changing the project type to maven: what does that do for me?

[pure cloud]

Maven will take care of all of the steps needed to build your project, such as including any dependencies you bring in

Also, if you're interested in becoming more serious about writing software it's generally better to use tools like Maven rather than relying on your IDE to build your project

[civic spoke]

good idea

[floral kindle]

The Damage it showed was only because it was close only melee damage

[pure cloud]

There's a short tutorial here that looks like it covers the basics: https://blog.jeff-media.com/how-to-create-your-first-minecraft-plugin-using-the-spigot-api-and-maven/

But, basically, Maven will expect your project to be structured in a certain way, e.g. your source code will bein src/main/java, other files that go in your .jar are in src/main/resources. When you run the maven command in your terminal Maven will read a file called pom.xml and compile your project which produces your .jar file

A basic pom.xml will look like this:

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>Your Java package</groupId>
  <artifactId>Your Plugin Name</artifactId>
  <version>1.0.0-SNAPSHOT</version>

  <name>Your Plugin Name</name>
  <description></description>
  <url></url>

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

    <dependencies>
      <dependency>
        <groupId>org.spigotmc</groupId>
        <artifactId>spigot-api</artifactId>
        <version>1.19.2-R0.1-SNAPSHOT</version>
      </dependency>
    </dependencies>
</project>

This tells Maven that you're using the Spigot API, so when you compile your code it can check that the function you're calling actually exist, you're calling them correctly, etc.

[quiet ice]

Do note that they also want to shade org.json:json

[pure cloud]

Now, for your JSON dependency you'd add it in the <dependencies> block. This tells Maven you're using that library. You can then tell Maven to include the code from the JSON dependency in your .jar, which will let Spigot load it when your plugin executes. This is called shading a jar, or producing a fat jar

[trim lake]

Im sorry for asking probably stupid question here again... But Im kinda lost. Is there way how to you TextComponent.formLegacyText in BaseComponent[]? I tried this but is not working Im getting error.``` BaseComponent[] testBuild = new ComponentBuilder(TextComponent.fromLegacyText(ChatColor.translateAlternateColorCodes('&', "&eLOOOOL"))).create();

[pure cloud]

This is the Maven page for that JSON dependency: https://mvnrepository.com/artifact/org.json/json/20220924
Notice the XML block -- you copy that block into the dependencies block. That will let it compile. Then you have to tell Maven to create a shaded .jar

[quiet ice]

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

[pure cloud]

It looks like TextComponent.fromLegacyText returns a BaseComponent[], butComponentBuilderonly has a constructor for BaseComponent.

[quiet ice]

BaseComponent is basically an abstract class for all what you want

[pure cloud]

Could you use an empty string as the base and call this append method which accepts BaseComponent[] https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/net/md_5/bungee/api/chat/ComponentBuilder.html#append-net.md_5.bungee.api.chat.BaseComponent:A-

[quiet ice]

why it isn't is beyond me

Oh lol, I may be stupid there

Although I'd still get rid of the whole new ComponentBuilder step and use .fromLegacyText from the get-go

[trim lake]

I tried this and not getting error. Looks like, that works. Gona testit thanks.

I want to use BaseComponent bcs I want to have multiple messages on one line (some of them clickable). I know, I can makeit true TextComponent.addnext but someone told me here to use BaseComponent bcs its easier. Idk...

Im just new in java idk what is best option to use.

[strong parcel]

I am changing the player's swim speed using the code from this thread, and something strange is happening that I do not understand. https://www.spigotmc.org/threads/how-to-increase-player-swimming-speed.547842/ When the multiplier is set to something like 0.825, the player swims faster than normal. If I am multiplying a vector by a decimal, shouldn't it make the player slower? Does this have something to do with the normal movement speed being 0.2?

When the multiplier is below 0.2, the player swims slower than normal.

Is it because the normal walking speed is the multiplier?

And by changing the multiplier, I am changing that...

[worldly ingot]

The multiply operation adds one first, then multiplies

So you should be adding a modifier that multiplies the value 0.825 - 1

Oh, sorry, you're using vectors, not attributes. That's what I get for not reading the thread you linked

[torn badge]

Anyone know how to properly cancel InventoryClickEvent with ClickType SWAP_OFF_HAND?

If I cancel it the clicked item doesn't move but rather duplicates into the off hand slot

[torn badge]

size()

[undone kernel]

💀

[torn badge]

Works for me

What version?

[chrome beacon]

1.5.2 💀

[torn badge]

tf

[torn badge]

What's the type of getOnlinePlayers()?

[undone kernel]

1.5.2

idk

[torn badge]

Check it

Open implementation

[undone kernel]

so

[torn badge]

Okay on an array it should be length

[undone kernel]

yeah but size() doesn't exist 💀

[torn badge]

length not size()

size() is on newer versions

[undone kernel]

well then what do I do ;- ;

[torn badge]

Which symbol could it not find?

[undone kernel]

it just takes me to the bukkit.getOnlinePlayers

[torn badge]

I see no error there

[undone kernel]

right here

can't do shat in 1.5.2 💀

[torn badge]

Anyone know about this?

[kind hatch]

Are you sure it's actually duplicated? It might just be some desync between the client and server. Usually clicking on the item in your inventory will refresh your state and the item will be removed.

[undone kernel]

what's an alternative to

Bukkit.broadcastMessage```
since it's deprecated

[sacred hamlet]

hello everyone !
who helpe me please ?

            Location loc = new Location(block.getWorld(), x1,y1,z);
            

            if( block.getWorld().getNearbyEntities(loc,1,1,1,(entity -> entity.getType() == EntityType.ITEM_FRAME))){
                block.breakNaturally();
                System.out.println("Breack");
            }else{
                System.out.println("Erreur");
            }
            ```

i go in get ITEM_FRAME for locality

ps: sorry i am french ^^

[undone kernel]

yeah I'm having a hard time tryna understand what you mean by this "i go in get ITEM_FRAME for locality"

[kind hatch]

?? It's not deprecated.

[worldly ingot]

It is on Paper. Likely what they're using

Best to ask for support with Paper API in the Paper Discord

[undone kernel]

alr ok

[kind hatch]

I always forget that's a paper thing.

It's so dumb.

[undone kernel]

yes yes it si

is*

[sacred hamlet]

I am trying to check if an item frame is placed to coordinate

[dim bronze]

whats the site to find spigot mappings to mojang mappings?

[river oracle]

screamingsandles

https://nms.screamingsandals.org/

[dim bronze]

thank you

[undone kernel]

how can I make this available everywhere like I put this in the main class and it works in all of em

[vital yacht]

You can use static, I'd recommend moving it to a util class though

[undone kernel]

alr thanks

[vital yacht]

No problem

[undone kernel]

ik ik i'm just using it for this one thing

also bruh

[undone kernel]

i have no idea what this means other than something is wrong with my onEnable thing

[vital yacht]

I'm going to assume you didn't register commands in your plugin.yml
Also, Objects.requireNonNull will still throw an error, if you don't want an error thrown you have to use an actual null check

[undone kernel]

they're registered

[vital yacht]

Can you send your plugin.yml?

[undone kernel]

  #Health Commands
  heal:
    usage: /<command>
    description: Heals you or another player
  feed:
    usage: /<command>

  starve:
    usage: /<command>
    description: Starves you or another player
  suicide:
    usage: /<command>
    description: Kills you or another player

[vital yacht]

You only have 4 commands there but 7 in the class

So you need to register the rest

[undone kernel]

shit i'm stupid

[vital yacht]

Also did you use /reload?

[undone kernel]

I was thinking about the health commands

[undone kernel]

yes very much so

I am to lazy to restart a server

[vital yacht]

Yeah you don't really want to do that

It's going to break a lot of things

[undone kernel]

it breaks essentials I know that

but nothing really happens to mine

but thanks

[vital yacht]

Just don't ever use it in production

[undone kernel]

alr

fps go brrr

yeah about that is this just paper

[vital yacht]

That will suppress any other null warnings though

[undone kernel]

bc i'm starting to think paper is doing some weird things

[vital yacht]

I would recommend moving your command registration to another method

Especially if you do this

[undone kernel]

like what?

[vital yacht]

// call this in onEnable()
private void registerCommands() {
  // register commands here
}

Yeah

I'll edit it

[undone kernel]

you're

    @SuppressWarnings("ConstantConditions")```

is being really annoying now

it's highlighting it

[vital yacht]

You didn't move the commands into the new method

[undone kernel]

ok that fixed it

[vital yacht]

Don't forgot to call registerCommands() in your onEnable()

[undone kernel]

look at all this little code

idk it's some code I stole from yt

[vital yacht]

If you're going to use code from YouTube make sure you understand it

[undone kernel]

i know it gets the config and the options and then saves it

can I do events the same way

[worldly ingot]

You can do one of two things, both of which do different things

this.getConfig().options().copyDefaults();
this.saveConfig();

// OR
this.saveDefaultConfig();```
The former copies the default keys and values from the config.yml in your plugin, then re-saves the config with those default values in your plugin config directory. The latter basically copy/pastes the config.yml from your plugin into your plugin config directory if it doesn't exist yet

[undone kernel]

OR

        this.getConfig().options();
        this.saveDefaultConfig();
``` because it's what I used and i know

and it works

[vital yacht]

Yes, you can make a method called registerEvents
I usually do something like

List.of(/*events here*/).forEach(this::registerEvent);

[worldly ingot]

The first line in your snippet does literally nothing. Nor does getConfig().options().saveDefaults() UNLESS you call saveConfig() after

You can just have saveDefaultConfig(); That's it. All you need

[undone kernel]

so I copied this and it made this

alr thanks

[vital yacht]

Make sure you know what it does first

[worldly ingot]

Not necessarily. Consider this situation.

# This file is in your /plugins/MyPlugin/config.yml
FirstValue: 69

# This file is in your plugin's default config.yml file (the one you export with your plugin)
FirstValue: 69
SecondValue: 420```
Running `getConfig().options().copyDefaults()` and `saveConfig()` will copy `SecondValue: 420` into the config.yml in your server files, whereas running `saveDefaultConfig()` will not because the file already exists on disk

[undone kernel]

i don't which is which I skipped doing it

[worldly ingot]

The values in the config.yml exported with your plugin are also defined as defaults

It's basically automatically doing addDefault() for you

[undone kernel]

alr now i'm confused to I keep the default thing or no

[worldly ingot]

No, Catto. You can remove it lol

You should only need to call saveDefaultConfig()

[undone kernel]

bruh I forgot verifying changed my name 💀

[worldly ingot]

ye

[vital yacht]

Yeah I need to change my name at some point lol

[undone kernel]

alr masterofthefish

[worldly ingot]

If you end up doing that, give me an @ and link me your Spigot profile, I'll update it on Discord. We have to do it manually

[vital yacht]

I will thank you

[undone kernel]

I'm gonna change it to darklife12345

[worldly ingot]

Welllll do it after you've changed your forum name lol

[vital yacht]

You have to donate $10 I think it is

[undone kernel]

once I figure out how to do it

[undone kernel]

where exactly am I supposed to find this setting

[vital yacht]

@undone kernel

[undone kernel]

well damn

i guess i'm stuck with this name for now

[sterile token]

I mean i didnt steal tho because if you explain me how it works they are not stealed at all

[vital yacht]

Wait you’re the 1.5 person from HelpChat

[undone kernel]

i am

[undone kernel]

also i've decided to stop with 1.5.2 i'm going back to 1.19

[vital yacht]

Nice

[fervent panther]

Hi I'm making a sword that shoots cobwebs and I wanna either delete or explode a cobweb after it's been placed. Is there a good way of doing this?

Here's what I'm currently doing

if (customItemId.equals("spider_sword")) {
        World world = player.getWorld();

        FallingBlock cobweb = (FallingBlock) world.spawnFallingBlock(player.getLocation().add(0, 1, 0), Material.COBWEB.createBlockData());

        cobweb.setDropItem(false);
        cobweb.setVelocity(player.getLocation().getDirection().multiply(0.8));
}

[undone kernel]

also what's the thing to use custom items in recipes

[sullen marlin]

put a tag in the cobweb PDC and then use the falling block event

?pdc

[undone axle]

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

[sullen marlin]

EntityChangeBlockEvent I think

[fervent panther]

Thanks!

I'm new to Java could you give me some advice on organizing my project?

I was trying to take a screenshot but it's not working for some reason

[sullen marlin]

Must verify to send images

[fervent panther]

oh

Here

This is my current project structure

[sullen marlin]

Seems fine

[fervent panther]

Should I make a separate class to for all entity related events?

[dusk flicker]

honestly wouldent think thats a structure of someone new to java

like, thats better than most lol

[fervent panther]

Like where would I put EntityChangeBlockEvent

haha thanks

[sullen marlin]

You could have a class that handles all events related to the cobweb sword

[dusk flicker]

Generally when it comes to listeners, I create classes based on what the event is going to be used for. Example I would have any listeners related to a certain aspect of the game in one class

[sullen marlin]

Or the itemevents class is fine, since it's an item still

Rip

Just lost power

[dusk flicker]

oooof

[sullen marlin]

Oops wrong channel

[dusk flicker]

lol

[fervent panther]

Ok thanks!

[undone kernel]

alr so I have this sword code

    public ItemStack ultimateSword() {
        ItemStack ultimateSword = new ItemStack(Material.DIAMOND_SWORD, 1);
        ItemMeta meta = ultimateSword.getItemMeta();
        meta.setDisplayName("§4§kscary§1Ultimate Sword§4§kscary");
        meta.addEnchant(Enchantment.DAMAGE_ALL, 10, true);
        meta.addEnchant(Enchantment.KNOCKBACK, 10, true);
        meta.addEnchant(Enchantment.FIRE_ASPECT, 10, true);
        meta.addEnchant(Enchantment.DURABILITY, 10, true);
        AttributeModifier dmg = new AttributeModifier(UUID.randomUUID(), "generic.attackDamage", 70.0, AttributeModifier.Operation.ADD_NUMBER, EquipmentSlot.HAND);
        meta.addAttributeModifier(Attribute.GENERIC_ATTACK_DAMAGE, dmg);
        ultimateSword.setItemMeta(meta);
        return ultimateSword;
    }```
and whenever I try to add an attribute it breaks my event to explode on right click
```java
                if (e.getItem().getItemMeta().equals(itemManager.ultimateSword().getItemMeta())) {
                    if (!cooldown.containsKey(p.getUniqueId()) || System.currentTimeMillis() - cooldown.get(p.getUniqueId()) > 5000) {
                        cooldown.put(p.getUniqueId(), System.currentTimeMillis());
                        p.sendMessage(colorize("&aYou've used the Ultimate Ability!"));
                        p.getWorld().createExplosion(p.getLocation(), 15f);
                    } else {
                        p.sendMessage(colorize("&4You can't use this for another &e" + (5000 - (System.currentTimeMillis() - cooldown.get(p.getUniqueId()))) / 1000 + " &4seconds!"));
                    }
                }```
anyone got any idea why this is happening

[fervent panther]

When you change an attribute the item stops exploding on right click?

Are you grabbing a new ultimateSword in mc after making the change in code?

[undone kernel]

no it's when I added it

when I added the attribute for more damage the event stopped working

[fervent panther]

Did you get a new sword in minecraft?

[undone kernel]

i mean technically I have the sword

[fervent panther]

Yes but the new sword has a different meta

when you're checking if the item the player using is the sword in the event it's comparing the meta including the new attribute

[undone kernel]

yeah

that's what it should do

to make sure the sword is authentic

[fervent panther]

yes

but if you don't get a new sword in minecraft after making a change to it in the code it won't detect is as the correct sword

your old sword isn't authentic anymore

[undone kernel]

i have no idea what you're trying to say

it's just one sword

OH do you mean like I get the sword with the updated code?

[fervent panther]

yeah

[undone kernel]

because yes I've done that and no it doesn't work

[fervent panther]

Ah ok

I don't have much spigot knowledge so I don't think I can help but I'm curious what attribute you're adding

[undone kernel]

damage

the sword without the attribute works but the one with it won't

[fervent panther]

How are you getting the sword?

[undone kernel]

did you not see me run the command in the video

[fervent panther]

oh I missed it lol

Looks cool

[undone kernel]

so whenever I run that command it should give me the updated sword

[loud frost]

This question is extremely related to what I have made in the past (and am currently refactoring) lol

How are you determining if your item is the sword in the event code?

nvm i see now

Its because when you add the attribute its metadata changes

so your conditional will always return false if anything is added.

You need to find a different way to verify the item

[drowsy helm]

just use pdc

so much easier

[digital plinth]

anyone know if you can force change a mob's texture to something else like protocallib's disguise

[drowsy helm]

protocol lib doesnt change textures

it just spoofs which entity is actually there

[digital plinth]

ah

so i have to make the client download a resourcepack?

[drowsy helm]

for texture, yes

[digital plinth]

okie

and can you like

give a mob a tag

and apply custom texture to mobs with tags only

i did it with items before

[drowsy helm]

iirc, no

[digital plinth]

tsk

:<

okay thx for the info

[digital plinth]

wait wait then how does nametags work on mobs

like the rainbow sheep

and cat

[drowsy helm]

pretty sure thats clientside

like hardcoded

[digital plinth]

is it something you can change with texture packs?

i think each mobs have their own texture

[digital plinth]

texture packs override right?

[fresh timber]

How can I change the hardness of a block?

[river oracle]

AFAIK you can't I'm pretty sure all those values are locked in nms

I doubt you find something but I'd suggest digging around nms

[drowsy helm]

you cant directly but if you want to change mine speed time you can either use nms to send block break animations at specific times or mining fatigue 1000 then time it

[fresh timber]

hm oh yea

I could add mining fatigue if they are targeting it

wait is there an event for someone starting to break a block or is that just like interact event?

[drowsy helm]

yeah BlockDamageEvent or smth like that

then theres an Abort event

[fresh timber]

whats the abort event for

[drowsy helm]

if they abort breaking it

[fresh timber]

oh ye ok thx

I was abt to give up when I saw ppl using nms

it looks so confusing

[drowsy helm]

just use remapped

its easy

[fresh timber]

whats that

[drowsy helm]

mojang mappings for nms

just doesnt use obfuscated names

[fresh timber]

ima just use mining fatigue for now xd

wait... is there a way I can add mining fatigue but not make their hand move super slow

there must be cus hypixel does it

[river oracle]

Packets probably

[fresh timber]

for their dungeon hub

never done packets

[river oracle]

There's no avoiding nms 😈

[fresh timber]

😱

do I need any extra repositories/dependencies for nms to work cus I cant seem to get it to work.

[remote swallow]

?bt

[undone axle]

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

[remote swallow]

also remove the -api on the dep

[fresh timber]

I dont see a dependency/repo on this page

[undone kernel]

how do I use that

[drowsy helm]

?pdc

[undone axle]

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

[drowsy helm]

its just an nbt wrapper

use an id to differentiate items

[digital plinth]

can you make a zombie attack? like play the attack animation with no target in mind

[vital yacht]

Feel free to take a look at this: https://github.com/Fisher2911/CustomBlockMining some stuff needs to be fixed because I transferred it over to my plugin that I used for my server, but it should give you a pretty good idea of how to start

I used PacketEvents which is a very nice library

[vital yacht]

There’s a bug where it doesn’t get called if they switch blocks though

[remote swallow]

you build spigot then you can use all of spigot in ur plugin

[pine island]

is there a way to change the hit velocity of a player so for example i listen for a playerHitEvent and then make it so that their knockback is decreased by 25%?

[icy beacon]

hey, could anyone help with #1043942626472230923 ?

[summer scroll]

Can you save a list of ItemStack inside an ItemStack, with pdc perhaps?

[icy beacon]

it doesn't seem that itemstack has pdc unfortunately

nbt maybe?

https://www.spigotmc.org/threads/tutorial-storing-custom-data-on-itemstacks-in-1-13-2.354283/ this looks interesting too

[drowsy helm]

yes

just use base 64 encoding

[icy beacon]

so itemstack does have pdc?

[drowsy helm]

yes

[icy beacon]

strange, didn't see that in the docs

[drowsy helm]

wait wdym does have pdc

[summer scroll]

So save it as a string, technically?

[drowsy helm]

yes a string, but its encoded

[icy beacon]

..persistent data container?

[drowsy helm]

not just 'saving'

yes ik what pdc is but your question doesnt make sense

[icy beacon]

for example Player extends PersistentDataHolder

and you can use its pdc

[summer scroll]

It's from ItemMeta.

[icy beacon]

ItemStack does'nt

[icy beacon]

ohh

yeah i guess it does

[summer scroll]

Alright, thank you.

[icy beacon]

forgot it was a thing 😄

[drowsy helm]

i have a gist if you want to see how

[sacred hamlet]

What is list of event please (i check item frame place but i dont have évent)

[drowsy helm]

should be BlockPlaceEvent

[sacred hamlet]

Item frame is a entity non AT block

[drowsy helm]

probs HangingPlaceEvent

[sacred hamlet]

I loock this but i loock Système.out.printer("évent") but 0 log is get

[quaint mantle]

How can I make an item given to myself when I join without giving me multiple times? Like I got the item then when I rejoin I get it again, is there a way I can update the item instead of giving me over and over?

[mighty pier]

you cant put custom characters and use Bukkit.getLogger.info()

[onyx fjord]

Why isn't it in English

Lol

[quaint mantle]

I am trying to figure out how can I check if it's not null?(https://prnt.sc/7NN_0PC3MVxm) this is my code (https://prnt.sc/FDKHbcLBKLlw)

when I try to move any other item rather than my sword it gives the error

[mighty pier]

current item is item on the cursor

wait

no

[drowsy helm]

use pdc

[mighty pier]

or

[quaint mantle]

pdc?

[mighty pier]

spinnenballe

[quaint mantle]

?

[mighty pier]

@alpine herald

[sonic goblet]

?pdc

[undone axle]

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

[mighty pier]

oh is that like the thing

wher

i forgot

[onyx fjord]

It stores data in item

And stuff like that

[quaint mantle]

ah

so I try to check the custom data will it not be null when I move other items?

I'm trying to cancel the move and drop event of my custom item but other items can move

oh okay

[summer scroll]

@drowsy helm any comment on this code? https://paste.md-5.net/ilucevetuy.php

[drowsy helm]

looks good to me

probably better to use array though

not a huge deal

[ivory sleet]

Im not buoobuoo but maybe try-with-resources

[humble tulip]

^^

So you don't have to manually close the streams

[glossy venture]

why does my scoreboard flicker?
it looks like its only there for one tick
im using the bukkit api, i made a class to assist me
builder class: https://paste.md-5.net/wozilamago.java
code:

    private void updateScoreboardFor(Player player) {
        ScoreboardBuilder builder = ScoreboardBuilder.newBoard("kitpvp");
        builder.title(kitPvpScoreboardTitle).displayAt(DisplaySlot.SIDEBAR);

        final String prefixLine = ChatColor.GOLD + "" + ChatColor.BOLD + "| " + ChatColor.WHITE;
        if (scoreBoardTick % 12 * 5 == 0) /* current session */ {

            builder.addLines(ChatColor.GOLD + "" + ChatColor.BOLD + "» " + ChatColor.WHITE + "Session");
            builder.addLines(prefixLine + "Kills: " + ChatColor.RED + "69");
        } else /* total */ {

        }

        builder.update().show(player);
    }

i call this code every tick with a runTaskTimer

for each player

oh wait

i bet its switching to the empty liens

[humble tulip]

Why are you creating a new scoreboard every tick

[rough drift]

^

There's no need

[glossy venture]

ill optimize it later

i just want to get something working

its still flickering tho

[opal juniper]

probably cause u change it every tick

[glossy venture]

how would i clear the objective

what is an entry

[opal juniper]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scoreboard/Scoreboard.html#registerNewObjective(java.lang.String,org.bukkit.scoreboard.Criteria,java.lang.String,org.bukkit.scoreboard.RenderType)
Like that?

[opal juniper]

the player name i imagine

[keen silo]

Hey, is the "ProxyServer" Class the replacement for the "BungeeCord" Class?

[glossy venture]

i cant just replace the old objective

oh nvm i can unregister the old one

[cobalt marlin]

Is there a way to make a dropped item despawn faster or increase its age? I want to make an item I spawn in the world despawn quickly without changing the global value

[glossy venture]

with nms you could edit the NBT tag

@sterile token opinions?

[remote swallow]

very A tbh

[echo basalt]

there's a lot more to it

[orchid gazelle]

Lmao

Button is the simplest menu element that just represents an item with an optional click handler

I have multiswitches that let you cycle between options and all

Nice job bro

[echo basalt]

me

[sterile token]

Oh ilusdionvjro

[orchid gazelle]

Lmao

[remote swallow]

hand it over

[sterile token]

Sorry i just seen the photo

[echo basalt]

I'm wondering how I'll animate it

[sterile token]

Discord is working for thetrush

[echo basalt]

but this is basically bootleg photoshop

on a very low resolution

[sterile token]

Oh ok

I prefer the oldsytem tho

[echo basalt]

this will be retrocompatible

I'll add some api methods that get the items from the pattern mask

the old system was way too simple and things like toggle switches are a pain to make

as it was made for static menus

[orchid gazelle]

Yo bois and girls

Any ideas how to force the server to send an update of a custom entity to the client?

[echo basalt]

send a metadata packet

containing ALL the data

[orchid gazelle]

Every tick..

then the updates would stack

[echo basalt]

why you want to do that

[orchid gazelle]

Because FallingBlocks do not get updated every tick

[echo basalt]

fallingblocks are a pain lmao

you just teleport them, their metadata doesn't change

[orchid gazelle]

And therefore the clients are doing weird precitions which lets the fallingblocks look like fucking skyrockets

[echo basalt]

you're tryna spawn a stationary one?

[orchid gazelle]

Oh I have done that already

[echo basalt]

client does predictions, you gotta send velocity packets each tick

[orchid gazelle]

Now that sucks

[echo basalt]

and maybe teleport it once in a while

[orchid gazelle]

I gotta get every player to send it to then too

Ouf

[remote swallow]

check radius

[orchid gazelle]

Yes

I know

[echo basalt]

just loop through all players in the world

then do distanceSquared checks

and all

[orchid gazelle]

Still kind of annoying isn't it

[echo basalt]

eh

if you're at that level, you're probably abstracting away half of it

[orchid gazelle]

Oh yes bro XD

Wait lemme show you something

U like my fallingblocks?

[remote swallow]

oh

god

[orchid gazelle]

(They also have a blueprint system attached and are getting saved and loaded via json)

[glossy venture]

hm i dont think having the scoreboard constantly updating on another thread really helped the flickering

server crshed

[orchid gazelle]

<:

[worn tundra]

bros scoreboard doing nasa trajectory computations

[glossy venture]

it was flickering

might have been client side

idk

[orchid gazelle]

Don't mind my business, only like 30 hours of work in total

Eh more like 40

[glossy venture]

60 fps scoreboard updating

its still fucking flickering

what the fuck

[civic wind]

I know why

You’ve got to allow for the molecules to combine and photo synthesise which then activates a chain reaction to the quantum nexus particles

That’s your problem right there

[glossy venture]

ah yes

of course

[civic wind]

You can thank me later

[remote swallow]

the easiest way to solve that problem is turn your monitor off

cant flicker is you cant see it

[glossy venture]

https://tenor.com/view/lil-yachty-drake-oprahs-bank-account-meme-laptop-gif-20803826

[orchid gazelle]

Ebic did you think anyone is dumb enough to spawn stationary MULTI-Fallingblocks?

[glossy venture]

tf is a multi fallingblock

[orchid gazelle]

Just what the name tells you

[glossy venture]

multiple?

[orchid gazelle]

this

[glossy venture]

oh

yeah so multiple

[orchid gazelle]

Yeah

Have not found anything online so I began writing that by myself =(

And I lost my mind multiple times, while reading through Server internals

[vital yacht]

Why not just set gravity to 0?

[echo basalt]

that's not how it works

[orchid gazelle]

^

[vital yacht]

Why not?

[echo basalt]

just try and see

fallingblocks are special

and I just prefer to mount them on armorstands because fr they painful

[orchid gazelle]

1. The Entity will despawn after 400 ticks
2. The Entity despawns when hitting a ground instantly
3. The client predicts movements so it will look like a skyrocket into the ground

[echo basalt]

I'd rather make them client-sided

and spam packets

[glossy venture]

ok now scoreboard only updates when marked needed

[orchid gazelle]

Yeah one thing, I gotta have collision and so on lol

[echo basalt]

than deal with the bukkit impl

[glossy venture]

flickering fixed

[vital yacht]

I was just looking at their code a couple days ago and I swear they have a check for it but maybe I’m not remembering correctly

[echo basalt]

you gotta write your own boundingbox with rotation n all

because like

hell naw

just make a combined boundingbox

[orchid gazelle]

to be real the code is 95% nms 5% Bukkit

[echo basalt]

I know

I do funky nms shit sometimes

I've been messing with so many fake blocks lately

making a full client-sided prison system

[orchid gazelle]

Thats a lot of "fun"

[remote swallow]

i love when my brain decides its time to go smooth

[orchid gazelle]

Yeah who doesn't?

[remote swallow]

normal people

ItemStack baseItem = null;
