[torn shuttle]

because discord didn't send it

I know it's printing villager isn't valid, that's what I specifically told it to print

that is also specifically my issue

[chrome beacon]

um... did discord die or smth the same thing just happened to my reply

[timid kraken]

umm so i looked more into this and apparently it requires a md5 hash, and i have 0 idea on how to get one and what hash is it even asking for. could you provide some insight?

[chrome beacon]

It's the hash of the resourcepack

It's to validate the file recieved

[dire marsh]

DatatypeConverter.parseHexBinary(hash)

[torn shuttle]

yeah this issue consistently only happens during startup

what's up with that

[timid kraken]

i haven't worked with hashes how do i go about generating one for my pack?

[torn shuttle]

seems like something is busted with world loading

[timid kraken]

?

[dire marsh]

get the hash from some site

[eternal oxide]

Why not use the spawn method with a consumer to set all your options?

[dire marsh]

upload the resourcepack zip file

http://onlinemd5.com/ for example works

just select sha1

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#spawn(org.bukkit.Location,java.lang.Class,org.bukkit.util.Consumer)

[timid kraken]

ok thanks a lot!

[torn shuttle]

🤷

[dire marsh]

then you want to put that sha1 into that method I sent you, as that will make it into a byte array

[eternal oxide]

The consumer is run on the entity before its spawned so you get to do all your modifications before its added to the world.

[chrome beacon]

Are you on windows?

[torn shuttle]

useful but wouldn't really fix my current issue

[eternal oxide]

Your issue is likely due to world loading and mob spawning timings

if you use a consumer it doesn't matter

your entity will be spawned when its ready

[timid kraken]

ok thanks a lot!

[torn shuttle]

how would a consumer help when it's just not ever spawning

[timid kraken]

mac

[torn shuttle]

consumers modify a spawn, right? they don't schedule one

[chrome beacon]

;/

idk then

[eternal oxide]

They modify the Entity. I don;t believe your entity is not spawning

[torn shuttle]

well you better believe it

it isn't

[eternal oxide]

I just think its not spawned when you expect it to be

[torn shuttle]

it never gets flagged as valid

[outer crane]

Anyone knows if I can access the Vault API async?

[eternal oxide]

depends on the plugins its hooked into

[outer crane]

I think the only one I have right now is Towny? Is that safe?

[eternal oxide]

probably not

[outer crane]

damn i wish there was some actually good claims plugin

towny works nicely for users but is a pain for admins

anyway, thanks

[eternal oxide]

The point of Towny is its run by users not admins

[outer crane]

but its painful to manage

[eternal oxide]

Set it up and you are done. No admin to do

[outer crane]

such as "emergency mode" when it decides to corrupt once in a while

anyway, im getting carried away

[eternal oxide]

ah well, yea corruption has been a thing for a long time

[sage swift]

no issues in my experience, only on my end when i did something wrong

or rarely when the server crashed

[eternal oxide]

I never experienced a corruption unless I did somethign silly myself.

[sage swift]

had a lot of crashing back in the day when i was first starting

but that's why there are automatic backups!

[torn shuttle]

I still remember when we could expect corruption with every update

[ivory sleet]

Don’t

If it’s economy it will be most likely be essentialsx which iirc does not support it, maybe for permissions (luckperms)

[eternal oxide]

GroupManager would likely be ok, but I'd not guarantee it

[torn shuttle]

I just can't see how it's not spawning it when I ask it to

clearly it's not null

it just goes from existing to not existing instantly

[eternal oxide]

Is the chunk actually loaded?

[torn shuttle]

yeah and also ffs I think the consumer thing worked just now even though it shouldn't

argh

this is so dumb it's not materially any different...

oh and now it didn't work

cool

these rng-based issues are the best

[eternal oxide]

Its different in the fact the consumer runs before spawning but the Entity is valid. Its possible the chunk is being unloaded if you are using Paper.

[torn shuttle]

        try {
            //this.villager = (Villager) spawnLocation.getWorld().spawnEntity(spawnLocation, EntityType.VILLAGER);
            Consumer<? extends Villager> consumer = new Consumer<Villager>() {

                @Override
                public void accept(Villager entity) {
                    // do something
                    entity.setRemoveWhenFarAway(false);
                    entity.setPersistent(false);
                    entity.setAI(false);
                    new DeveloperMessage("Spawning entity: " + entity.getType());
                }

            };
            this.villager = spawnLocation.getWorld().spawn(spawnLocation, Villager.class, (Consumer<Villager>) consumer);
            this.uuid = villager.getUniqueId();
        } catch (Exception ex) {
            new WarningMessage("NPC " + npCsConfigFields.getFileName() + " tried to spawn in an invalid location. " +
                    "This may be due to region protection preventing it from spawning correctly. If not, delete the location" +
                    " in its configuration file and try setting it up again.");
            ex.printStackTrace();
            return;
        }

        if (this.villager == null)
            new DeveloperMessage("Villager is null");
        if (!this.villager.isValid())
            new DeveloperMessage("Villager isn't valid");

still returning not valid

it does run the spawning entity message

[eternal oxide]

If you are doing it in the consumer don;t bother checking isValid

It won't exist in the world yet

[torn shuttle]

it never exists in the world

[eternal oxide]

so all the code is running, but it never appears in game?

[torn shuttle]

yes, that's what I'm saying

except on a reload

if I reload the plugin and this code runs again but the world's been loaded the whole time it works just fine

also this is a 1.17 exclusive issue

[eternal oxide]

Then you issue IS that the world/chunk is not loaded

[torn shuttle]

this code worked for every single update before this

the world is loaded, the location exists

you can't make a valid location with a valid world without the world fundamentally existing

also it runs after the world initialization

[eternal oxide]

just because your location is valid doesn't mean teh chunk is loaded

[torn shuttle]

sure, that's why I also had code to load the chunk in manually

no difference

[eternal oxide]

chunk load I'm fairly sure is not instant when you call load

same as unload

you have to wait for it to be available

easy test, set yoru loaction to spawn

[torn shuttle]

this world does not keep spawn chunks alive

[eternal oxide]

then change the setting so it does

it will prove or disprove your issue

[torn shuttle]

fyi

[eternal oxide]

you are likely going to have to delay your spawing a tick until the chunk is loaded.

[torn shuttle]

try {
            //this.villager = (Villager) spawnLocation.getWorld().spawnEntity(spawnLocation, EntityType.VILLAGER);
            Consumer<? extends Villager> consumer = new Consumer<Villager>() {

                @Override
                public void accept(Villager entity) {
                    // do something
                    entity.setRemoveWhenFarAway(false);
                    entity.setPersistent(false);
                    entity.setAI(false);
                    if (!entity.isValid())
                        new DeveloperMessage("Minecraft is a busted-ass game");
                    new DeveloperMessage("Spawning entity: " + entity.getType());
                }

            };
            this.villager = spawnLocation.getWorld().spawn(spawnLocation, Villager.class, (Consumer<Villager>) consumer);
            this.uuid = villager.getUniqueId();
        } catch (Exception ex) {
            new WarningMessage("NPC " + npCsConfigFields.getFileName() + " tried to spawn in an invalid location. " +
                    "This may be due to region protection preventing it from spawning correctly. If not, delete the location" +
                    " in its configuration file and try setting it up again.");
            ex.printStackTrace();
            return;
        }

the consumer dev message #1 runs

it's not valid even in there

[eternal oxide]

Its not spawned yet so I would expect that to be false

[torn shuttle]

yeah, yet

keeping the chunks alive seems to bypass the issue so I guess that's the issue (?)

I have to assume this changed for 1.17, how come this was never an issue before?

[eternal oxide]

yep, your best approach, is place a ticket on the chunk, then fire in a delayed task the spawn

at the end of your spawn remove the ticket (if you are done spawning)

[steady rapids]

anyone knows how can I get server warns? i coded an easy launchpad plugin but if the velocity is too much, my console spams warnings about it. Is it possible to make an event when one of those warnings pops up?

[18:40:17 WARN]: Excessive velocity set detected: tried to set velocity of entity #0 to (9.890552185889112,5.0,-1.249544380443629).

[sour loom]

if i do player.getLocation().distance(someOtherPlayer.getLocation()) what type of data will it return? a double or a vector?

[unreal quartz]

distance (double)

though you should consider using distanceSquared as distance will sqrt the result

[hasty prawn]

getServer().getLogger() I think. Although you probably should heed the warning and not set the velocity so high

[steady rapids]

any idea on what is the max velocity?

[hasty prawn]

Nope, I would just try to tweak the numbers until you like the velocity & it doesn't spam

[steady rapids]

kk

ty

[torn shuttle]

the plot thickens

the chunk claims it's loaded when the code runs

[eternal oxide]

I guess it lies then

[torn shuttle]

well it's a problem innit

[robust crypt]

abcd

[eternal oxide]

yep

Have you tried with chunk tickets?

[torn shuttle]

I don't know if chunk tickets are something specific but I have changed the code to be initialized based on chunk loads

?paste

[undone axle]

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

[torn shuttle]

https://paste.md-5.net/azeqajavah.java you get the general idea

[eternal oxide]

I'd also delay 1 tick after the chunk load event to run your code.

[torn shuttle]

well it's not that the code in the chunk load doesn't work

it's that it doesn't run because the chunk is already loaded lol

[eternal oxide]

at startup (1 tick after) get a list of loaded chunks

[torn shuttle]

I already have another alternative that works based on delays after boot but I would really like to have a way of doing this that isn't 100% jank from the start

[eternal oxide]

yep

work arounds are a pain

[torn shuttle]

I will say this proves that the chunk was loaded the whole time

[eternal oxide]

I believe there are different levels of loaded now

[torn shuttle]

wait what

is that exposed on the api?

[eternal oxide]

I think I remember Choco talking about it a week or so back

Not to my knowledge

[eternal night]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/pull-requests/866/overview
Would be the PR to address a lot of the issues in regards to entities and chunk loading

[eternal oxide]

My fix would probably be...

1. Add a chunk ticket for any Entities I want to spawn.
2. Run delayed any spawn code for those entities.
3. Check if the Entity was already spawned in some other server startup.
4. Use the spawned Entity or spawn a new one if none exists.

[outer crane]

This page contains both my pom.xml and stacktrace, any idea what I'm doing wrong? https://paste.gg/p/anonymous/a06223f76af4434f9719584ae24316bc

I'm trying to use guice for my api and plugin

[torn shuttle]

so what's the point of chunk tickets exactly? just loading chunks permanently?

[eternal oxide]

java 1.8 and spigot 1.17 are not a match

[eternal oxide]

Yep, it force loads and keeps the chunk loaded until all tickets are removed

[shut field]

why does this not cancel the event?

[eternal night]

your IDE already yells at you

lol

[unreal quartz]

read the warnings your IDE gives

[robust crypt]

why does lmbishop have to be here :(((

[unreal quartz]

lemme guess

[torn shuttle]

I guess the point is to make sure the chunk doesn't try to unload between the time you load it and the time the frankenstein's monster of a code that enforces waiting delays after a chunk load right

[unreal quartz]

you're here to abuse ewen again

[hidden delta]

String cannot be use with ==

[robust crypt]

how do i set the score of my scoreboard to 69

[unreal quartz]

yep

[shut field]

.equals()?

[robust crypt]

how did u know ...

[outer crane]

that was a typo with me putting it on the paste site, it wouldn't compile in the first place if that was my normal pom.xml 😅

[hidden delta]

You need to use equal or equalOrIgnoreCase

[shut field]

k, thanks

[unreal quartz]

objectives don't have scores

[worldly ingot]

getScore()

Then set its value

[grizzled warren]

I'd like to get the ip and username with the uid, anyone know how?

[worldly ingot]

Dude, use your IDE

[eternal oxide]

Yep, literally just prevents anything unloading until you are finished.

[unreal quartz]

no, you get the score of a specific entry

[hidden delta]

getScore(string).setScore(int)

[worldly ingot]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scoreboard/Objective.html#getScore(java.lang.String)

[torn shuttle]

yo choco is it true that there's different chunk loaded states with 1.17?

[unreal quartz]

the objective itself doens't have a score

[robust crypt]

no way someone just dmed for free nitro

no way

[torn shuttle]

this is such jank

[robust crypt]

xd

[robust crypt]

thx

[torn shuttle]

and also doesn't really fix the core issue of it happening when the chunks are already loaded to start with

[eternal oxide]

nope

[quaint mantle]

become hacker man

then cry when you realize you dont know what the fuck youre doing

[eternal oxide]

@worldly ingot Was it you the other day having a discussion about chunk load levels? Something about them being new?

[worldly ingot]

Don't think so

[robust crypt]

host the server and when the player log in check console

[eternal oxide]

ok

[torn shuttle]

should I even report this as a bug

it's clearly busted somewhere

[eternal oxide]

It possibly is a bug as it doesn;t happen on earlier versions

[torn shuttle]

yeah it certainly didn't

[eternal oxide]

You would have to come up with a reliable method to replicate it

[torn shuttle]

uh

it's not too hard

on startup create a world, get a location in that world, spawn an entity on the same tick

or even better spawn 100 different entities spread out a little bit

you'll get about 20% of them

[eternal oxide]

You would have to demonstrate that it would work 100% in 1.16

[torn shuttle]

you can run the same code in 1.16

I've been doing it to thousands of entities and it never missed

[eternal night]

https://hub.spigotmc.org/jira/browse/SPIGOT-6547 this might be related

as you will find in the issue, there is an open PR to introduce chunk loaded level (e.g. isEntityLoaded) to the API

[eternal oxide]

interesting

That is the same issue

[eternal night]

PR has gone kind of stale tho

not much of a fan of that

[torn shuttle]

I guess it's a deeper-seated issue

[sharp bough]

how can i use anvils to get user inputs? i cant manage to find anything on google

or some useful API

Inventoryframework doesnt explain it well enough

[muted idol]

hey there so right now i have this JSON string. now im wondering how would i go about desteralizing this string to for example only get the info the json object has which id is 0?
my JSON string: [{"X":-887,"Y":100,"Z":482,"ID":0},{"X":-24,"Y":54,"Z":284,"ID":1}]

[quaint mantle]

r u talking about getting the text field?

[sharp bough]

yea i wanna make an anvil gui to allow player input text

but i cant find anything working

[quaint mantle]

https://github.com/WesJD/AnvilGUI

[muted idol]

@quaint mantle do you mind helping me once you're finished with @sharp bough ?

[quaint mantle]

no, because i have no idea about your problem

[sharp bough]

i already saw that, i get an error

maybe i did something wrong

?

[muted idol]

have you ever worked with json?

[lusty cipher]

AnvilGUI is awesome

[quaint mantle]

ofc i have

[muted idol]

i am basically asking how i would go about getting the "ID" value from my json object

[muted idol]

great

[quaint mantle]

just not in Java

[muted idol]

haha np man

[lusty cipher]

Spigot has Gson built-in iirc

[quaint mantle]

okay this is a bit of a lie, I have, but im not very good at it, i always use google lmao

[eternal oxide]

JsonObject json = new Gson().fromJson(reader, JsonObject.class);
int id = json.get("id").getAsInt();```

[ivory garnet]

hi, how can i get a instance of a block but a instance of a block vanilla

[eternal oxide]

A Block is a representation of the location in the World

You can get a snapshot of that block

[sharp bough]

class: https://paste.md-5.net/bujasigodi.java
error: https://paste.md-5.net/arilumegup.coffeescript

any ideas?

using anvilGUI

[quaint mantle]

its your java version lol

what mc version are you trying to target?

[ivory garnet]

ok but if i do : Chest chestblock = (Chest)localisationofmyblock.getBlock(); it does not work

[sharp bough]

im in 1.16.5

[quaint mantle]

Hey does anyone know a good tutorial of spigot?

[eternal oxide]

(Chest) location.getBlock().getBlockData() I believe

[quaint mantle]

i wanna learn

[sharp bough]

the source code

in yt

[quaint mantle]

you would need to compile it yourself for java 16

actually wait

you're using java 8 right?

[ivory garnet]

thank you but i would next do PersistentDataContainer tilesttc = chestnbt.getPersistentDataContainer();

[sharp bough]

yes

[quaint mantle]

update to java 16

[eternal oxide]

You do not use anything nbt to get the PDC

[sharp bough]

Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) Client VM (build 25.291-b10, mixed mode, sharing)```

[quaint mantle]

update to java 16

[ivory garnet]

its juste a name

[sharp bough]

k

[ivory garnet]

"chestnbt" are just "chestblock"

[smoky oak]

what's the event that fires when something grows (not when its random ticked)?

nevermind got it

trying to disable mushrroms destroying end portal

[ivory garnet]

so, that can work ?

[eternal oxide]

You would just location.getBlock().getState().getPersistentDataContainer()

[smoky oak]

Does that work for spawners?

[ivory garnet]

ok thx

[ivory garnet]

The method getPersistentDataContainer() is undefined for the type BlockState

its the error

[eternal oxide]

cast to chest

[stone sinew]

How can I convert BlockData cbd = Bukkit.createBlockData(String); to IBlockData? I can't cast it...

[eternal oxide]

((Chest) location.getBlock().getState()).getPersistentDataContainer()

[eternal oxide]

IBlockData would be an NMS interface?

[stone sinew]

I think i found it...

BlockData cbd = Bukkit.createBlockData(entry.getValue());
IBlockData ibd = ((CraftBlockData) cbd).getState();

[eternal oxide]

yep nms

[stone sinew]

Yeap this worked. Finally damn xD

[stone sinew]

Yes sorry lol.

[prisma needle]

Hey guys! I've been taking a look at adding custom tab complete suggestions to custom commands (in bungeecord). I've looked it up online and haven't found a clear answer on how to use it, or how to add the tab suggestions to a command. Are there any tips or resources I could use? Thanks :)

[sharp bough]

it was that thank you

how to remove a path from .yml?

tried with config.set("path", null) but doesnt work

[quaint mantle]

config.remove?

doesnt exists

[quaint mantle]

or smth like this

[final monolith]

i searched too 😅

[quaint mantle]

it's time for javadocs!

[unreal quartz]

well that is how you remove it

by passing null

[final monolith]

config.set("path", null)?

already tried

[unreal quartz]

how does it not work

what is the behaviour

[final monolith]

wait, i will debug

to see

show me that error

[unreal quartz]

sned your code

[final monolith]

e.getKey().getName() returns "name" (its correct)

[unreal quartz]

i mean the full thing

[final monolith]

public static void deleteVariable(Player p, String name) {

        File player = new File(instance.getDataFolder() + "/data/" + p.getUniqueId() + ".yml");
        FileConfiguration playerConfig = YamlConfiguration.loadConfiguration(player);

        for (Map.Entry<DataAPI, Player> e : data.entrySet()) {
            if (e.getKey().getName().equalsIgnoreCase(name)) {
                data.remove(e.getKey());
                playerConfig.set(p.getUniqueId() + "." + e.getKey().getName(), null);
            }
        }

        Main.getInstance().saveCustomConfig(playerConfig, player);
    }

[unreal quartz]

the error is the line above

use an iterator

[final monolith]

data.remove(e.getKey());?

[unreal quartz]

you can't remove from a list while you iterate over it with a for loop

[ivory garnet]

if i do Chest titlesttc = locplyrc.getBlock().getState().getPersistentDataContainer();
getPersistentDataContainer() are in red

[final monolith]

remove after the iterator?

[unreal quartz]

you can add it to a list to remove after, or use an Iterator

[eternal oxide]

you didn;t cast the state to Chest

[final monolith]

can you give me example for the Iterator?

[unreal quartz]

i am sure you can google one

[final monolith]

oh ok

[ivory garnet]

ok but how can i do ????

[eternal oxide]

the exact code I showed you and you quoted back to me

[eternal night]

final Chest chest = (Chest) location.getBlock().getState();
final var pdc = chest.getPersistentDataContainer();

there

java

you can one-line it similar to how elgar did it

but then you don't have the chest, which is sad

[quaint mantle]

why use var when you know what it is?

[eternal oxide]

less typing 🙂

[eternal night]

because I don't want to write out the class name ??

you always know what it is lol

java is not a dynamically typed language lol

[hasty prawn]

So lazy... it's so much easier to read & understand if you don't do that.

[quaint mantle]

thats what im thinking ^

[eternal night]

I mean, if you need the type definition you do you /shrug

[hasty prawn]

The compiler might be able to infer but if someone else comes along and reads your code they might have a difficult time inferring.

[unreal quartz]

its their source code, let them do whatever they want

[eternal night]

idk there is very specific java documentation on this

[hasty prawn]

I know, but just seems like it'd be bad practice to use var

[quaint mantle]

nobody told them to change it

[ivory garnet]

@eternal oxide thx thx

[eternal night]

Yeah dang, java is really the only language in which you can just let the compile infer the type

rust and kotlin are gonna cry in a corner

golang does too

[ivory sleet]

Infer what type? 😮

[eternal night]

the PersistentTooSlowToUseContainer

just such a long word 😭

[ivory sleet]

Ah lol

Yeah spigot enterprise 😌

[eternal night]

tho I guess, flame ItemMeta not PDC

[ivory sleet]

Lol

[ivory sleet]

Type inference and anonymous exposure

[sour loom]

So if the player that i want is lets say 20 blocks away from me on the x axis, will .distance() return 20.0?

[eternal night]

yes

[unreal quartz]

yes

[sour loom]

Thankyou

[unreal quartz]

well as long as there is no difference in y and z ofc

[ivory sleet]

I would argue for that it may add readability when used in the right place

[hasty prawn]

How would it?

[sour loom]

How will that work?

[hasty prawn]

I guess if the naming is obfuscated or something then it could to an extent I guess

[unreal quartz]

it would be the magnitude of the vector

[ivory garnet]

@eternal oxide oops, i have do
Chest chestnbt = (Chest) locplyrc.getBlock().getState();

PersistentDataContainer tilesttc = chestnbt.getPersistentDataContainer();
but the Chest chestnbt = (Chest) locplyrc.getBlock().getState() do a error

[ivory sleet]

You might have something like ByteArrayInputStream in a twr block, in that case just declaring a var might make it easier to read.

[eternal night]

runtime tho ?

var is also just useful if you actually name your variable.

final var persistentDataContainer = ...
final PersistentDataContainer persistentDataContainer = ...

like, it is just doubled

[ivory garnet]

you speak to me ?

[eternal oxide]

Probably imported the wrong Chest

[sour loom]

So it would calculate like a 90° rectangle?

[hasty prawn]

Yeah fair enough, I see the use-case here

[ivory sleet]

Also anonymous exposure which is like super pog

[sour loom]

Yo get the closest distance to the player

[ivory sleet]

Or whatever it’s called

[ivory garnet]

what i must import ?

[eternal oxide]

What import have you used?

[sour loom]

I mean the Pythagorean theorem

[ivory garnet]

org.bukkitidk

[unreal quartz]

e.g if i was +5 on x, y and z, then distance would return sqrt (sum of squares) away

[eternal oxide]

you need the Block one

[unreal quartz]

yes

[robust crypt]

omg why is he here

[sour loom]

Ok, thankyou

[eternal night]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/Chest.html

this chest

specifically

[ivory garnet]

so org.bukkit.block.Chest;

[ivory garnet]

thx

[eternal oxide]

yes

[robust crypt]

how do i set score REEEEE

its still 0

[granite stirrup]

i think you need previous scores to set it

so you need a 0-68

but scoreboards cant even go past 16 i think

[robust crypt]

wtf

is this scam

[eternal night]

what ? Scores can definitely go up to 16 and way beyond

[granite stirrup]

pretty sure you can only have 16 scores

[robust crypt]

than explain how health scoreboard works

with 20

[eternal night]

I think idkidk is talking about order of scores on the scoreboard

[hasty prawn]

Thats the value, not the positioning

You're setting the position to 69

Which isn't valid

[eternal night]

Fam what ?

the position is just the value on the sidebar

[granite stirrup]

you cant display more than 16 on sidebar

[eternal night]

Yes

[hasty prawn]

Oh wait yeah 🤔 hang on

[eternal night]

individual scores

[robust crypt]

im talking about below names

[eternal night]

but they are just trying to create a single score with value 69

[robust crypt]

.

[eternal night]

which should be perfectly fine

[granite stirrup]

oh

[robust crypt]

BELOW NAME PLS

no side bar

[hasty prawn]

Are you making a separate Scoreboard for each player or is it all on the same scoreboard

[robust crypt]

same

i want everyone to see that ewen is fat

i might be wrong wait

    private Scoreboard createScoreboard(String Ewen_Is_Fat_XD) {
        final Scoreboard scoreboard = Bukkit.getScoreboardManager()
                .getNewScoreboard();
        final Objective objective = scoreboard.registerNewObjective(
                "test", "dummy",
                ChatColor.RED + "Ewen_Is_Fat_XD" + ChatColor.RESET);
        objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
        objective.setDisplayName(ChatColor.RED + "Ewen_Is_Fat_XD" + ChatColor.RESET);
        objective.getScore("Ewen_Is_Fat_XD").setScore(69);
        return scoreboard;

[sour loom]

Why you bully him?😕

[hasty prawn]

Try getScore(ChatColor.RED + "Ewen_Is_Fat_XD" + ChatColor.RESET)

[robust crypt]

wat

but i want it to be 69

[hasty prawn]

Change this:
objective.getScore("Ewen_Is_Fat_XD").setScore(69);
to this
objective.getScore(ChatColor.RED + "Ewen_Is_Fat_XD" + ChatColor.RESET).setScore(69);

[robust crypt]

:(

i gotta open my server again

[sour loom]

What do you guys do to run something every 10seconds? Do you multiprocess or smth? Or just puting it in a different class and doing while would work?

[granite stirrup]

[ivory garnet]

the block can have custom nbt ?

[eternal oxide]

no

[ivory garnet]

ok thx

[granite stirrup]

tile entities yes

but no other blocks

[eternal oxide]

true

[granite stirrup]

tile entities is kinda like blocks with nbt

tbh i dont think you can set nbt of a tile entity in vanilla like custom nbt cuz i tried and it didnt work

[eternal oxide]

Thats ok, we have PDC 🙂

[granite stirrup]

thats 1.14+ xd

[eternal oxide]

Life begins at 1.14

[granite stirrup]

not everyone uses that

if your making a public plugin you probs wanna support to 1.12 atleast

[eternal night]

nah lol

[granite stirrup]

because some people still use old verisons

[hasty prawn]

If only Mojang would add 1.8 pvp back we could all use the latest :(

[eternal night]

either go full on 1.8 or just latest

the intermediate versions are pretty useless

[granite stirrup]

we need toggle

[eternal night]

The jeb_ patches look very useful

[hasty prawn]

Yeah we do, I don't really understand why they insist on not adding a gamerule for it

[eternal night]

I mean you want a unified experience over all of minecraft

they saw something wrong with 1.8 PVP

so bringing it back makes no sense

[hasty prawn]

Sure it does. Get people to stop using the version that's like 6 years old. Clearly people liked it, why change it?

Compromise. Add both.

Let the server decide which it uses.

[eternal night]

tbh old combat mechanics already does a LOT of what 1.8 did but people just are hardstuck on the "omg this one single thing is not the same I cannot uses it"

[robust crypt]

didnt work

[hasty prawn]

Oh yeah for sure, OCM is fantastic. Only thing it really can't reproduce is sword blocking afaik

Still think it should be a Mojang feature so 1.8 can die

:/

[granite stirrup]

doesnt it make a shield in off hand

[eternal night]

idk I think they just gotta work on their new combat patches

[sour loom]

Anothwr question, does using spigot latest version allow older versions of minecraft java to play on it? If so, where can i see how old?

[eternal night]

spigot does not

there is viaversion

[hasty prawn]

Yeah but it's not perfect

[eternal night]

which does what you are describing

[hasty prawn]

Doesn't really feel the same

[eternal night]

Yea but the extra effort on their end to implement a combat system back that feels "exactly the same" is a lot

for a system that, remind you, they do not see fit as a combat system for minecraft

Also, according to bstats 1.8 is dying steadily

[hasty prawn]

It's a PvE system. IMO they're being a little petty not doing something about it, people very clearly avoid 1.9 combat, especially when it comes to pvp. All bug fixes & features are completely worthless to PvP servers because of that change.

[eternal night]

idk man, according to bstats not even 9% of spigot servers run 1.8 at this point

so either there is not a single pvp server in the 1.9+ servers, or OCM is good enough for most people that aren't petty af or bstats sucks

[hasty prawn]

9% of servers doesn't necessarily mean 9% of the playerbase. I mean just look at Hypixel, they HAVE to support 1.8 so they're effectively locked to 1.8's features. Imagine what they could do if they had access to all the new stuff.

[eternal night]

hypixel does not use vanilla server software anyway

nor spigot or paper

[sour loom]

Is there a way to see a players client version?

[peak depot]

idk but maby its because 1.8.8 is not counting to 1.8

[hasty prawn]

It's still built off the vanilla server software is it not? 🤔

[eternal night]

nah

[granite stirrup]

some hypixel gamemodes are 1.12

[eternal night]

doubt it

[hasty prawn]

Such as?

[eternal night]

if hypixel server software is still based of vanilla, they are doing something wrong

[granite stirrup]

buildbattle?

[hasty prawn]

Well, either way, they're still locked to mainly 1.8 features because of clients :l

[granite stirrup]

cuz buildbattle has terracotta i think and thats a 1.12 feature

pretty sure

[hasty prawn]

Nope, it supports 1.8

[granite stirrup]

it does?

[hasty prawn]

I mean it might have terracotta but it must just change the block to 1.8 clients

[eternal night]

also very much something you could do btw.

enable 1.9+ features only for those clients

[hasty prawn]

So you're saying the server should take the time to make sure their stuff supports both versions?

[eternal night]

honestly they should just work out their combat update, release it any just keep watching 1.8 servers die

[granite stirrup]

ok but im pretty sure there is some 1.12 stuff

[hasty prawn]

Probably is

[eternal night]

if you think your userbase is petty enough for care about 1.8 combats vs OCM

then yeah, your server will have to do more work

[hasty prawn]

Could just be avoided if they added the gamerule, that's my point lol

People ARE petty enough to stay on 1.8

So all that effort & time going into new stuff is mostly wasted anyways

[quasi flint]

Ocm Not that Bad afaik

[hasty prawn]

Might as well put a little time into re-adding 1.8 combat and have ALL features be used!

[quasi flint]

Not many points that are bad

[eternal night]

dude, 1.16 was the most successful release of minecraft in a while

their work is definitely not wasted

[quasi flint]

Time to write a mod ;7

Well there already is one

[hasty prawn]

Yeah OCM is great, and even my server we use latest with OCM. I'm not saying praise 1.8 and use it, nonono. I use latest.

It's just a MAJOR headache for everyone that people still play on a 6 year old version.

[quasi flint]

Neat

[quasi flint]

Building blocks are so wasted

[hybrid spoke]

1.8 🤢

[granite stirrup]

but also whats keeping most people on 1.8 is performance

[hasty prawn]

Well true but that's an entire different issue LOL

[hybrid spoke]

performance? 1.12.2 & 1.16 are mostly more stable

[quasi flint]

That's just java and bad optimization

[granite stirrup]

1.16 and 1.17 are laggy af

[hybrid spoke]

buy a better computer

[granite stirrup]

i dont mean laggy

i mean like its just slow

[quasi flint]

Well not everyone has money to do that

[granite stirrup]

the server is just like uses so much memory

[quasi flint]

They overload a already broken enough game with more things. Making the game even more unstable

[granite stirrup]

and it barley can handle 100 players

bungeecord cant even handle that much you have to balance out the players just to fix that

[quasi flint]

Rewrite resource intensive parts of the game would maybe welp

[eternal night]

it is a decade old code base ¯_(ツ)_/¯

[quasi flint]

That's what I am syaing

[hybrid spoke]

they did a huge step by upgrading to java 16

isnt that enough for the following 5 years?

[granite stirrup]

performance got worse in 1.17 tho

[eternal night]

lol

[granite stirrup]

it dropped like 100 fps

optifine only helps like gaining 5% back

[quasi flint]

At least it does smth

[eternal night]

sodium works a lot better

[granite stirrup]

for some people it actually doesnt(cuz people have said)

[quasi flint]

Well that's forge

[granite stirrup]

lol

[eternal night]

sodium is fabric

lmao

[quasi flint]

:v

:c

[granite stirrup]

i never tried sodium tho

[eternal night]

give it a shot

[granite stirrup]

¯_(ツ)_/¯

[hasty prawn]

Never even heard of Sodium, gonna try it. Ty 👀

[quasi flint]

Can't be worse

[granite stirrup]

maybe one day

[quasi flint]

There is sodium and lithium

And like 2 more

1 of em was Phosphor

[chrome beacon]

Sodium
Lithium
Phosphor
Hydrogen

Those are the mods maintained by JellySquid (and the Caffeine group)

[timid kraken]

is there an event for when the player has fully connected and loaded into the world?

PlayerJoinEvent fires before the player has loaded the world

[granite stirrup]

it shouldnt?

[chrome beacon]

Listen to PlayerJoinEvent and delay with one tick

[timid kraken]

yeah i am

[chrome beacon]

Then what's the problem?

[granite stirrup]

PlayerJoinEvent should fire as soon as the player loads into the world?

your server must be slow as ass if 1 tick delay doesnt fix it

[timid kraken]

i am prompting a resource pack installation it works fine locally but when i do it on my server (which gives me like 150ping and slow world load) it shows for a sec then dissapears before i even have the chance to interact with it

[timid kraken]

yeah it is

[granite stirrup]

then just do more delay?

[timid kraken]

so is there an event for a full load/connection?

[chrome beacon]

Don't think so

[timid kraken]

hmmm

[granite stirrup]

pretty sure PlayerJoinEvent does that

[timid kraken]

no afaik joinevent fires even before the player loads the world

[granite stirrup]

¯_(ツ)_/¯

[coral sorrel]

better*

[muted idol]

hey there how would i go about parsing (getting) the CheckpointCounter int?
json code:

{
    "CheckpointInfo": {
        "CheckpointCounter": 0
    }
}

[granite stirrup]

no

it dropped alot of fps

[coral sorrel]

what did it drop?

not really

have the same fps as before

[granite stirrup]

about 100 fps dropped

[coral sorrel]

some say they even have more fps

on 1.17

[granite stirrup]

it dropped like 100 fps on 1.17

[coral sorrel]

for you

doesn't mean for everyone

[granite stirrup]

in singleplayer

but in multiplayer i have the same fps in 1.16

[coral sorrel]

and?

[granite stirrup]

it still dropped alot in singleplayer

[chrome beacon]

It depends on many things

For some people it got better and for others not

[slow oyster]

Does anyone use Hibernate or something similar in their plugins at all?

[granite stirrup]

?

[slow oyster]

I've been using a yaml file basically as a flat file database at this point and it's getting a bit ridiculous now

[granite stirrup]

¯_(ツ)_/¯

idk wtf Hibernate is

probs go to help-server

[slow oyster]

It's an ORM

[granite stirrup]

this is for development help not for helping with a plugin

[slow oyster]

No lol, it's an ORM for managing relational databases

[granite stirrup]

¯_(ツ)_/¯

idfk

[slow oyster]

true to your name I guess

[granite stirrup]

i dont use orm

or hibernate

dont even know what it is

cuz never heard of it

[torn oyster]

?paste

[undone axle]

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

[torn oyster]

okay

[unreal quartz]

i know a few people use it, but it's not very widespread

[torn oyster]

so i use the same method for connecting with mysql

[unreal quartz]

it's too.. 'enterprisey' for a simple application such as a spigot plugin

[torn oyster]

i used this method on my discord bot

im now making my plugin

but now it breaks

on my plugin

when it works fine on my discord bot

its giving this error

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

[unreal quartz]

maybe

if you sent code

and stopped typing like this

[torn oyster]

yes im doing that

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

[slow oyster]

True, I basically use it every day in work so I thought it'd be useful to use it in my plugin too

[austere cove]

When I'm in creative and I use my number keys InventoryClickEvent doesn't have ClickType.NUMBER_KEY

halp

[unreal quartz]

if you're used to using it then go for it

[granite stirrup]

why does it think thats js its not even that similar to js

[unreal quartz]

but i usually just handle the mappings myself

what is line 31..

whatever it is it's null

[eternal oxide]

Shouldn;t you be using https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/InventoryCreativeEvent.html

[unreal quartz]

Class.forName("com.mysql.cj.jdbc.Driver"); is that correct?

[granite stirrup]

LOLLLLLLL

[torn oyster]

no idea lol

[austere cove]

idk if that would get the correct click type tho

[torn oyster]

yes

[austere cove]

hold on

[torn oyster]

i tried without cj

[granite stirrup]

it has been months and forge still doesnt have 1.17

[torn oyster]

it says

"outdated class"

or something

[unreal quartz]

you still haven't told me what line 31 is

[torn oyster]

well this is on discord

line 31 is setConnection

and the rest of the stuff

[granite stirrup]

forge doesnt support 1.17

lol

[unreal quartz]

what is DriverManager

[torn oyster]

a java sql class

[granite stirrup]

forge is really fucking late to the party

[torn oyster]

that connects to a database

[unreal quartz]

still unconvinced that path is correct

[torn oyster]

what do you think it is

[unreal quartz]

and you're not even doing anything with is

[torn oyster]

you have to do that

[unreal quartz]

com.mysql.jdbc.Driver, you can check inside the spigot jar yourself

[torn oyster]

it initializes the class

it isnt in spigot

[unreal quartz]

yes it is

[torn oyster]

so they have their own version of it

wtf

[unreal quartz]

it's mysql connector/j, which is packaged with spigot

[torn oyster]

how do i not package it with spigot

[unreal quartz]

you don't not package it with spigot

[torn oyster]

now i know why it isnt working

[unreal quartz]

you use it

[torn oyster]

yes but i am using another mysql connector

[unreal quartz]

well then

have fun

[austere cove]

still not the right click type / inventory action

[eternal oxide]

Does it return NUMBER_KEY?

[austere cove]

action PLACE_ALL, type CREATIVE

[eternal oxide]

try just calling getHotbarButton() See if it returns anything other than -1

you could always getClick().isKeyboardClick() then test the hotbar

[austere cove]

nope slot is -1

[eternal oxide]

Broken then 😦

[quaint mantle]

Hi friends, what do you think of my code?
https://paste.md-5.net/fatucotiso.java

[unreal quartz]

could consider deferring the handling of each argument to other classes if you ever plan on expanding that command

[quaint mantle]

My question is, is the code bad?

🥲

[unreal quartz]

and you might want to inform the user that they can't access it from console rather than just having no feedback

not bad

[austere cove]

it's kinda messy

[unreal quartz]

just gonna have a lot more if/else if you ever plan on adding to that command, and soon you will have a 600 line long file

[ivory sleet]

If am I going to be honest, horrible

[unreal quartz]

is homesManager a class?

[quaint mantle]

yes

[unreal quartz]

any reason the whole thing is static

[ivory sleet]

Your code is fragile and rigid to start with

[quaint mantle]

What can I improve?

[ivory sleet]

First of all that nasty if else statement chain

Create an abstraction for each sub command

[chrome beacon]

Switches, language managers sub classes and general clean up to make the code easier to follow

[ivory sleet]

A function/method should only do one thing so another tip is to extract larger methods

[granite stirrup]

my brother ran 1.17 on java 8 in the minecraft launcher

how

he didnt change anything

[chrome beacon]

Also please follow naming conventions for class names

[unreal quartz]

well he didn't

[ivory sleet]

Also try not to jump from low to high level but that’s kinda enterprise pedantic thingy

[granite stirrup]

he did

i never seen him download java 16

[unreal quartz]

ok

[granite stirrup]

and he played with me on it before

[quaint mantle]

how to make this?

[unreal quartz]

doesnt minecraft download java now

[granite stirrup]

does it?

oh maybe it does but idk

[ivory sleet]

Dimensions google what polymorphism is

And inheritance

[quaint mantle]

What would you recommend I do?

[austere cove]

figured out it's a limitation of the protocol spec

[ivory sleet]

Start with learning Java capabilities fully, like for instance abstract classes, interfaces and such.

Then learn SOLID and design patterns.

[austere cove]

when you double click an item in your inventory to stack all items of the same type, is there a way to tell what slots you took items from?

[ivory sleet]

But fragile means that changing one part of the code would end up changing the behavior of your another part of your code, which now when I think of it might not be very visible in your code.

Rigid means when you want to change something it often leads to you having to change major parts of your code and ultimately changing something isn’t as trivial as it could be.

Just a short explanation

[quaint mantle]

Ohhhh

I got it, thanks. That's what was happening

Would it be recommended to put the ifs in the function?

[ivory sleet]

To prevent this we to make sure higher level modules don’t depend on lower level ones. This can be done by adhering to SOLID. Although to understand SOLID fully a good knowledge of OO and Java is a fundamental demand.

[granite stirrup]

sad when you want to require something thats in a folder up you have to do in lua lua package.path = package.path .. ';../?.lua'

[ivory sleet]

Uh yeah dimensions arguably

Usually creating a lot of functions which get composed to larger ones cleans your code.

Partly because we can have useful names for every function we declare.

[quaint mantle]

Would you like to make a messaging system by function, how would you recommend?

I currently use it.

🥲

[ivory sleet]

Uh that can be useful but make those fields final

Also read on the official Java naming specifications

[prisma needle]

I figured out how to make a tab completer for my command, however for some reason it stops working when there are more than 1 arg. It should suggest a tab completion of the number of args the command has, however it only shows "1". Likewise, if (args.length == 2) doesn't do anything. Any reason why the args would get messed up like that? (Bungeecord)

        Collection<String> suggestions = new ArrayList<>();
        suggestions.add(String.valueOf(args.length));
        return suggestions;
    }```

[ivory sleet]

That sound weird, your code looks like it would complete the args.length every time

[chrome beacon]

I really miss the Brigadier system for spigot. I know Commodore exists for bukkit but doesn't look like it works for bungeecord

I use this code but I get a nosuchfieldexception. How do I know whats the field called?

Do I have to manually check it?

Or like how is it in reflection?

[quaint mantle]

Anyone know how to make a sign input gui? I have done a lot of research but cannot find a way to make one.

[chrome beacon]

Well ItemStack is not ItemMeta so you can't cast it that way

[river spear]

thanks

[chrome beacon]

A simple Google search finds a lot of guides

Here's even a library you can use and update if needed: https://github.com/Cleymax/SignGUI

[vital ridge]

I changed #getDeclaredField("f") to footer but now theres no errors, I just cant log in and it just kicks me

With a nullpointerexception on screen.

[chrome beacon]

What version are you using?

[vital ridge]

1.16.5

[chrome beacon]

Then why are you using reflection for this

It's part of the API

[vital ridge]

Just to get more knowledge on this.

I know it is.

[chrome beacon]

Anyway for your nullpointer I'm guessing you need to set the header too

Decompile the class and see what it contains and then use reflection accordingly

[vital ridge]

Thank you, that fixed it.

Tho what do i need to check for to fill the declaredField?

The method parameter names?

[chrome beacon]

Well you should check everything

You need to know what things do

[vital ridge]

Aigh

[chilly reef]

is there a way to be more specific with the PlayerDeathEvent without using EntityDamageEvent.DamageCause because it does not show entity type

[granite stirrup]

.getEntity()?

or .getPlayer()?

[chilly reef]

doing that gets the player thats dying not the entity that is killing the player

[granite stirrup]

wait no

getDeathMessage()?

[chrome beacon]

getKiller can be used if it's a player

[granite stirrup]

or maybe getEntityType()?

[chilly reef]

get entity type would be player because it is asking for the dying player not the damaging entity

getDamager also does not work for some reason

[granite stirrup]

getKiller()?

[chilly reef]

only works if its a player that kills the player

[granite stirrup]

then switch to entitydeathevent

idk

[chilly reef]

okay i will try that thanks

[unreal quartz]

get the last damage cause

it will return the associated damage event

from which you can get the entity

[chilly reef]

how would i get the entity from that

oh i found it

[unreal quartz]

make sure it's an instance of EntityDamageByEntityEvent

[chilly reef]

with customizing death messages as context would that still work

[chrome beacon]

Most of the time

[chilly reef]

if(player.getLastDamageCause().getEntityType().equals(EntityType.)); this works

thanks

[chrome beacon]

The message will be messed up if something cancels the damage event

I would store entities in a weakmap

[final monolith]

oh sorry

[granite stirrup]

two things i hate in that code

"package net.redewhite.Data;"

[chrome beacon]

Just 2 👀

[granite stirrup]

and you named your class "Main"

[granite stirrup]

atm

i didnt look at all of it

[final monolith]

sorry guys im starting 😅

[granite stirrup]

its fine its just i dont like the capital in Data

[unreal quartz]

you have sent the wrong class

[final monolith]

Error: https://paste.md-5.net/ujomabudom.bash
Main: https://paste.md-5.net/ofitobiwil.java

[unreal quartz]

net.redewhite.Data.API.loadVariables(API.java:29)

[granite stirrup]

and you should name your main class as the plugin name

[unreal quartz]

you should learn to read these stacktraces

[granite stirrup]

we need API.java

not Main.java

[final monolith]

sorry

here is the API.class: https://paste.md-5.net/asoyemovoh.java

[granite stirrup]

playerConfig.getConfigurationSection(uuid).getKeys(true) this is null

pretty sure

[final monolith]

the error is because the configuration section is not set?

[granite stirrup]

is it in your file?

pretty sure it needs to be

[final monolith]

no

yeah, i think that is this

im gonna insert a if (!uuid == null)

[granite stirrup]

not the uuid

[final monolith]

its a example

😅

[granite stirrup]

i think you need to do before for loop if(!playerConfig.isSet(uuid)) return; but dont ask me on that one

[final monolith]

yeah, i will do this

[dense pulsar]

Is there any way to slap some data onto a player object that will stay on join/leave?

without writing to a file.

[opal juniper]

Lmaooo

[dense pulsar]

O::::

[opal juniper]

Literally the use of a pdc

[granite stirrup]

1.14+ though

[opal juniper]

Like you were describing it

[eternal night]

the agressive double slap

[dense pulsar]

I figured something like that existed lmao

[eternal night]

but not for the 1.8 plebs :>

makes me very happy

[dense pulsar]

am in 1.16.5

[granite stirrup]

sad thing is its only for 1.14+

[opal juniper]

Good

[granite stirrup]

1.16.5 has it

[opal juniper]

Good

[eternal night]

very good

[hexed hatch]

Imagine using 1.8 in 2021 lol

[dense pulsar]

i'll do 1.17 once I stop doing my worldedit cheese with commands and just use their API

[granite stirrup]

1.17 isnt stable

i recommend not using it

[ivory sleet]

I mean pdc still has to write/read to the disk

[eternal night]

wow xD

also 1.17 isn't stable ? what

[opal juniper]

Yeah it is??

[granite stirrup]

only when you quit and join or is it when the server shuts down idk

[hexed hatch]

I've had a server running on 1.17, it's pretty damn stable at this point

[eternal night]

you good ? 1.17 is latest isn't it

[hexed hatch]

But I am on Paper

[ivory sleet]

idkidk that’s the part I’m unsure of lol

[eternal night]

paper 1.17 has also been marked as "stable enough"

[opal juniper]

Yayyy

Paper cool

[granite stirrup]

fortnite has this new thing with a roblox logo on it

lol

[opal juniper]

Shut it

[hexed hatch]

That's so cool but who asked

[ivory sleet]

Yatopia tho

[granite stirrup]

idk i saw it

[hexed hatch]

Wow that's a relevant topic thanks for sharing said absolutely no one

[granite stirrup]

https://www.youtube.com/watch?v=yBfD-2PxXwE

[ivory sleet]

No need to be rude now

[final monolith]

solved, @granite stirrup thanks

[opal juniper]

So dumb they couldn’t convert to 1.17 smh

[sharp bough]

when you do Bukkit.gerServer().getVersion() you get the version of the spigot.jar of the server, or the version of the player?

[granite stirrup]

it died

[hexed hatch]

server

[opal juniper]

Player version lmao

[ivory sleet]

Oh yeah didn’t they disband the project jeff

[opal juniper]

Mhm

[ivory sleet]

[opal juniper]

What will I do now

[sharp bough]

but does the player version matter?

[granite stirrup]

cuz

it says in there discord

[hexed hatch]

Player version does matter lol

I mean, in what way are you wanting to know how it matters?

[sharp bough]

if you allow a player using 1.8 join a 1.16 server, this works just fine right?

[opal juniper]

Dafuq does player version mean

[ivory sleet]

What a good reason, totally couldn’t figure that out 😌

[sharp bough]

the client version

[opal juniper]

Oh, that ain’t a thing in spigot

[hexed hatch]

If you use a plugin that allows that to happen, that method will return whatever the server is running on

[granite stirrup]

how do you get client version?? nms?

[opal juniper]

No

[sharp bough]

but does it matter? does it make any difference? or should i just focus on the spigot.jar of the server?

[hexed hatch]

Probably by intercepting packets or some shit if it even is possible

[sharp bough]

ah

[opal juniper]

Yeah probably in the handshake packets or something

        }
    }
``` i just tested this by tping to y100 and falling and the message was the skeleton message

[granite stirrup]

that sucks

lua doesnt have switch cases

[dense pulsar]

@chilly reeflol wtf

you are putting semicolons at the end of the if statement

[chilly reef]

oh i didnt realize

[dense pulsar]

furthermore

[chilly reef]

all of the messages are the skeleton one i guess

even ones that i didnt specify

[dense pulsar]

you should also use else ifs

so you aren't checking the conditions unnecesarily

[chilly reef]

whats that

[granite stirrup]

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.

[chrome beacon]

A Switch statement would fit better here

[quaint mantle]

Im going to kill my self, thank you.

😭

[sharp bough]

get 9/11'ed?

[chilly reef]

shhh

[dense pulsar]

it would

[sharp bough]

bro thats fucked up

[quaint mantle]

Lmfao

[granite stirrup]

?

[chrome beacon]

Wouldn't kintetic energy fit better

[chilly reef]

maybe but explotions work too

[dense pulsar]

actually no, a switch statement wouldn't fit better there

i mean in the future yes, but he isn't just checking the EntityDamageEvent but also the EntityType which is an obj

it'd work for the first couple though

[quaint mantle]

where are they checking the entitytype?

[chilly reef]

for death message

[quaint mantle]

oh wait

i see what you're saying, was confused for a second

[dense pulsar]

also, I have a question ```java
event.setCancelled(true);
player.damage(1);

new BukkitRunnable() {
    @Override
    public void run() {
        player.setFireTicks(60);
    }
}.runTaskLater(plugin, 1);

is this a legit way to do it or am I being dumb

heres the full method ```java
@EventHandler(priority = EventPriority.HIGHEST)
public void onArrowHit(EntityDamageByEntityEvent event) {

    if (!(event.getEntity() instanceof Player)
            || !(event.getCause().equals(EntityDamageEvent.DamageCause.PROJECTILE))
            || !(event.getDamager().getType().equals(EntityType.ARROW)))
        return;

    Player player = (Player) event.getEntity();
    if (!PartyManager.inAMiniGame(player)) return;

    event.setCancelled(true);
    player.damage(1);

    new BukkitRunnable() {
        @Override
        public void run() {
            player.setFireTicks(60);
        }
    }.runTaskLater(plugin, 1);
}

[ivory sleet]

Wat

[dense pulsar]

how so

np

[chilly reef]

i removed the semi colons but all of the messages are the default messages

[dense pulsar]

    @EventHandler
    public void deathEvents(PlayerDeathEvent e) {
        Player player = e.getEntity();
        if (player.getLastDamageCause().getCause() == null) return;

        if (player.getLastDamageCause().getCause() == EntityDamageEvent.DamageCause.FALL){
            e.setDeathMessage(player.getDisplayName() + " landed on their feet and fucking died.");
        }
        else if (player.getLastDamageCause().getCause() == EntityDamageEvent.DamageCause.BLOCK_EXPLOSION){
            e.setDeathMessage(player.getDisplayName() + " got 9/11'ed");
        }
        else if (player.getLastDamageCause().getCause() == EntityDamageEvent.DamageCause.ENTITY_EXPLOSION){
            e.setDeathMessage(player.getDisplayName() + " got 9/11'ed");
        }
        else if (player.getLastDamageCause().getEntityType() == EntityType.SKELETON) {
            e.setDeathMessage(player.getDisplayName() + " was shot by a boner.");
        }
        else if (player.getLastDamageCause().getEntityType() == EntityType.ZOMBIE){
            e.setDeathMessage(player.getDisplayName() + " was eaten alive");
        }
    }

[granite stirrup]

@ivory sleet lua makes me very sad :( theres no switch cases

[dense pulsar]

dont use lua then

luaser

[granite stirrup]

i have to

im using computercraft 🙄

[dense pulsar]

lol lua was the only reason I didn't get super into computercraft

[ivory sleet]

That’s good

It protects you from writing rigid code

[granite stirrup]

atleast i have fake switch cases

[ivory sleet]

[dense pulsar]

back in my day we just try catched everything! didnt even use if statements

[ivory sleet]

[granite stirrup]

local test= {
        ["Something"]=function() print("test1") end,
        ["Something2"]=function() print("test2") end,
        ["Something3"]=function() print("test3") end
}

local test2 = {"Something","Something2","Something3"} 

for index, value in ipairs(test2) do
  test[value]()
end

[ivory sleet]

Map where the values are functions?

[granite stirrup]

its kinda like switch cases

[ivory sleet]

[granite stirrup]

["Something"] is the case

function() print("test1") end is what gets run

idk

[ivory sleet]

Btw

Doesn’t lua have the arrow syntax

[granite stirrup]

?

[granite beacon]

Why am I getting the error

[18:38:43 ERROR]: Could not pass event ProjectileHitEvent to LearningSpigot v1.0-SNAPSHOT
java.lang.NullPointerException: null

When doing this

    }

    public static boolean removeProjectile(Entity p){
        projectiles.remove(p);
        return true;
    }
}

[granite stirrup]

something is null

[eternal night]

if only you had java 15+

tho looking at it projectiles seems very null xD

[granite stirrup]

yeah but also doesnt the projectile get deleted?

when it hits

so wouldnt it not work anyway???

[eternal night]

what

the static set in the projectHelper

[granite stirrup]

no i mean in the game

[granite beacon]

it's for a particle system I'm using

[granite stirrup]

wouldnt the entity not exist anymore after it hits?

[granite beacon]

it's still in the set

but I think you can still get it

[granite stirrup]

so

the entity doesnt exist anymore isnt that object gonna be useless

[eternal night]

but it has to be removed from the set, else you are leaking memory

[granite beacon]

the weird thing is when I print e.getEntity().getType() it print out the type

public void onShootSnowball(ProjectileLaunchEvent e){
        System.out.println(e.getEntity().getType().toString());
        if (e.getEntity().getType().equals(EntityType.SNOWBALL)){
            System.out.println(e.getEntity().getType().toString());
        }
    }

but when I try to add it to the set it does the null error

[granite beacon]

and yeah that's why I did it

[granite stirrup]

because the Set is null

[eternal night]

your set is just null my man xD
