[eternal night]

Pls don't use

[tender shard]

it does what? o0

[eternal night]

That's the thing that turns your "true" into a byte

Horror

[tender shard]

it turns the string "true" into a byte?

[eternal night]

Because Mojang interprets the string true as a Boolean or something

Idk

Been a while

[tender shard]

I remember this very weird bug when deserializing itemstacks that have "json-looking" text stored as String in it's PDC

[eternal night]

It's shit, stay away from pdc and yaml

[tender shard]

and it would break everything and throw exceptions

[eternal night]

Like the combo

[tender shard]

e.g.

ItemStack item = ...;
ItemMeta meta = item.getItemMeta();
meta.getPDC().set(..., "{\"name\": \"mfnalex\"}");
config.set("myitem", item);
ItemStack item = config.getItemStack("myitem"); // <-- huge exception

I wonder if this was fixed meanwhile? I once opened a jira issue and md_5 said it's indeed a bug but he won't be able to fix it without breaking other stuff

[eternal night]

It has not

[tender shard]

damn

[eternal night]

Everything as a byte array is the vibe

[tender shard]

I should add a new data type to MorePersistentDataTypes lol

DataType.STRING_CONTAINING_JSON

[eternal night]

Or just, again, don't use spigots item yaml shit

[tender shard]

then what else are we supposed to use?

[eternal night]

Papers item to byte blob XD

[tender shard]

but

1. more than 30% of servers use spigot
2. then it's not human readable anymore

D:

paper should just contribute upstream more 😛

[eternal night]

Not really possible

[tender shard]

why not? honest question, why is this not possible?

[eternal night]

The people that contribute those patches would have to sign the cla

Else they cannot be contributed

[tender shard]

what's the problem with signing it?

[eternal night]

That some people don't want to ? Or that people who have written the patches just aren't around

Can't force them

Lol

[tender shard]

well that's sad

I mean it takes like 30 seconds to sign it

and it doesnt have any downsides or anything

[eternal night]

What ?

[tender shard]

which downside does it have?

[eternal night]

You are signing your rights to the patch away lol

That's the entire point

[tender shard]

yeah sure, I mean it's an open source project

who the fuck contributes to an open source project and then later says "ha you cannot use it, I wrote it"

makes no sense in my eyes

imho you already give the rights away by contributing to any open source thing, automatically. it's like... inherent to the idea of creating a PR

[eternal night]

Not at all o.o

[tender shard]

not sure if I phrased it correctly

my english is only good enough for small talk and to talk about pickles

[eternal night]

My MIT licenced Code still forces every sucker that uses it to include the licence and a credit

Spigot doesn't have to do shit

[tender shard]

hm I don't really think I get what you mean

[eternal night]

I mean, my paper patches will have my mail and username as credit. If we ever get rid of them and move them to commits, I'll be the author of that commit etc

Spigot just, absorbs your stuff

You loose any form of ownership of the code

Which is the entire point so no one can trash them like Bukkit

[tender shard]

yeah okay but what are you going to do with the ownership? sell it to someone or what?

or make paper remove it again when you don't feel like contributing anymore?

[eternal night]

I mean it's a licence discussion. This is more about moral and concept than anything else lol

[tender shard]

honest question, I cannot think of a legimite reason why keeping the ownership would be relevant

[eternal night]

No like a single plugin gives two shits about licencing

[tender shard]

so MiniDigger could just say "Nah I don't feel like MiniMessage should be in paper anymore" and then they'd have to remove it again ? or am I misunderstanding sth lol

i think I'm misunderstanding sth

[eternal night]

But at this point it's also just a dumb business move to contribute to spigot lol XD

[tender shard]

it's also always a question about where copyright starts and where it ends. for example I added these 4 translation key methods to spigot (well I PRed them) and then found out that paper does it basically exactly the same way. One could now say that I "stole" this but I wrote this shit myself. I mean it's just a few lines - now the question is, if two people write the same code without having copied each other, does that count as "stealing" that code?

because if that'd be the case, then every Hello World program would basically be stolen from s/o else

I even accidentally used the same variable names haha

nmsItemStack e.g.

but tbh how else would one call an NMS itemstack

[eternal night]

Yea it's a iffy thing obviously

Especially with how some fixes just, fhere is only one way to fix them

Or API that just, makes sense

[tender shard]

exactly

[eternal night]

Hence no one is going completely nuts about this kind of stuff

[tender shard]

that's also why I had this discussion with this dude on paper's discord about the bukkit api

[mighty aurora]

Quick Question. Would a valid method(this was suggested to me and it doesn't seem like it would work but I want to run it by some people who know more than me) to turn players completely invisible(armor and all) be to basically move their armor to an armor stand that is set to be invisible?

[tender shard]

I mean cmon, obv an interface that represents a player is called Player

[tender shard]

why not just use Player#setVisible(false) ?

[eternal night]

There is also player#hide and show

[tender shard]

oh yeah

[mighty aurora]

player hide prevents the player from taking damage.

[eternal night]

It does yea

[tender shard]

then use setVisible(false)

[mighty aurora]

I didn't know that was a thing.

thanks

[tender shard]

I am pretty sure it is

hide(...) basically makes it hidden completely from clients (they dont know this entity exists), while setVisible(false) just makes it not "render" them

unless I am mistaken

[eternal night]

But anyway, I mean no one is going nuts and screaming at spigot if something similar is submitted to them. Obviously don't like it too much because well, the extra apis we add is an advantage for us.

Don't know what setVisibke does tbh

[mighty aurora]

.setVisible on a player doesn't work

[tender shard]

well this one dude on stash sent a kinda passive aggressive comment lol

that already made me not wanna contribute anything anymore haha

[eternal night]

Well, md used to be rather careful on anything looking remotely like paper patches

[tender shard]

hm what about a potion effect with ambient effects set to false?

[mighty aurora]

doesnt prevent armor visibility

[eternal night]

No need to move the armour to an armorstand tho

[tender shard]

but isn't that what the CLA is for? I mean, I basically assured that everything I contribute is "my work", that's part of what the CLA says

[eternal night]

People do a lot of things

[tender shard]

so even if I stole it from paper, that'd be my responsibility and not Spigot's

[eternal night]

Well yea, does not hurt to still check

Does spigot have the sendEquipmentChange stuff

Might be better here for armour

[tender shard]

IIRC the CLA basically just says this:
"Everything I contribute was done by me and I have the rights of that code. But now it's yours. If I fucked up, that's my responsibility"

[tender shard]

yes

[eternal night]

Yet you'll also double check the road before crossing a cross walk just in case a car does not see you

[tender shard]

you mean like sendBlockChange but for equipment, right?

if so, yeah that exists

[eternal night]

Sure it wouldn't be your fault but safe is safe

[tender shard]

sure

[eternal night]

Oh yea

Might be nice to hide the armour then

[tender shard]

wait wait wait

does an invis potion not affect the armor?

[eternal night]

No?

[tender shard]

I never play minecraft, so I have no clue

lol

[mighty aurora]

it has no effect on armor

[tender shard]

how weird

[rich pewter]

How do you write to a yml file?

[tender shard]

do you have a FileConfiguration object?

If so, call save(File) on it

[eternal night]

Pdc for plugins when then

[tender shard]

that's your job

you are the pdc dude

I only write libs related to pdc

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/file/FileConfiguration.html

[tender shard]

btw is there any official docs or something that notify about api changes in paper? I know that spigot doesn't have any so I always miss the new stuff

[eternal night]

We usually release a little update post on the discord

😛

[tender shard]

half of the people here are banned from your discord

[eternal night]

Every like 2 weeks or month

Otherwise twitter gets the same post

If you use that

[tender shard]

I could create an alt discord account

not_mfnalex#0001

[eternal night]

Once I finish my thingy, I should start making YouTube shorts covering API changes

[jagged monolith]

There needs to be like a little changelog thing for the api on the website for it

[tender shard]

that'd be nice

[eternal night]

And get the fat stacks from YouTube

For doing shorts

For 3 people

[tender shard]

for spigot I usually just stalk this but it's a pain https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/commits

[eternal night]

It's not so bad lol

[tender shard]

yeah well but it also has entries like "Updated SnakeYaml" and stuff which are useless if you just want to see api changes

so yeah it's not perfect but it's okay

I'd rather like to see some blog posts or sth

e.g. when PlayerProfile was added in 1.18.1, NOBODY knew about it

[eternal night]

We need a slicedlime update video series for API 😦

A weekly podcast lol

[tender shard]

I want to see md_5 becoming a tiktoker

[eternal night]

I'd follow for sure

[tender shard]

same lmao

my boyfriend is such a weirdo, he has 17k followers on tiktok

[eternal night]

Famous af

[tender shard]

all his videos are shit

he's just lipsyncing some songs or similar

i never understood tiktok

[jagged monolith]

Neither really.

[tender shard]

on the other hand, there's many things I don't understand

I am a tax lawyer but I couldn't do my own tax returns lol

oooh TeleportCause.DISMOUNT was finally added

hi verano

we all saw you typing

[sterile token]

What would the best way, for having a common sender for bungee and spigot?

[tender shard]

create an interface that declares all the methods you need, then create a bungee module and a spigot module with a wrapper class for the underlying sender that implements your interface and just delegates the stuff to the underlying object

[eternal night]

Use adventure for everything 🙂

There ya go

[sterile token]

Yeah i did the interface but i dont understand how i wrap it

[tender shard]

we got geyser, to make bedrock players join java servers. we got viaversion to make 1.19 players join 1.8 servers. we got mohist to run spigot plugins on forge (well, more or less...).

When will we have a thing that allows spigot plugins to run on bungee lmao

[tender shard]

maven or gradle?

[sterile token]

Maven

[tender shard]

you create two modules. E.g. MyAPI-spigot and MyAPI-bungee

[sterile token]

Also there is more, there is a way for playing mc via netscape

[tender shard]

both have a class that wraps the underlying sender, and then delegates

e.g.

[sterile token]

That is were im mixxed

[tender shard]

public class SpigotCommandSender implements MyUniversalCommandSender {

  private final CommandSender sender;
  
  public SpigotCommandSender(CommandSender /* the spigot one */ sender) {
    this.sender = sender;
  }

  @Override /* declared in your MyUniversalCommandSender interface */
  public String getName() {
    return sender.getName();
  }
}

basically like how CraftPlayer etc works

[tender shard]

this would be in your spigot module. then you do the same for your bungee module

however I don't see many usecases for this. Bukkit and Bungee player objects are extremely different

[sterile token]

yeah i thought something like that and then how i would call it via the Command?

[tender shard]

I mean, all they have in common is that they have a name, a uuid, and that you can send messages. oh and that they can have permissions

that's basically all they have in comm on

[tender shard]

wdym?

[sterile token]

Im doing it for my cmd framework that why

[tender shard]

your command framework would then just take a MyUniversalCommandSender instead of a bukkit or bungee one

[sterile token]

yeah i know that

[tender shard]

from spigot you'd just do new SpigotCommandSender(theActualSpigotCommandSender)

[sterile token]

I have smth like this public abstract boolean execute(Sender sender, String[] args);

[tender shard]

same for bungee

[sterile token]

Let start from begining, how would you do the command registration for bungee/spigot

I dont really understand the delegation part between diff platforms

[tender shard]

uwu

[buoyant viper]

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[tender shard]

ha noob

you need the spigot docs

[sterile token]

What?

[tender shard]

chads like me know everything by heart

[sterile token]

I know how to register command on spigot and bungee, just dont know how to create the command framework so its support both of them

Mainly the delegation part

[tender shard]

verano sometimes I think you're living in a different world lol

I wasn't talking to you

[sterile token]

HMNN

🤔

[sterile token]

You broken my brains, are you talking with ghosts?

💀

[tender shard]

I'm doing a trivia in #bot-commands brb

[sterile token]

ohh ok

[rich pewter]

if there is a list of player names in the plugin comfig.yml file, how would i get them as an OfflinePlayer[]?

[sterile token]

Get them via the uuid/name

[tender shard]

anyone up for some trivia?

verano meet me in the trivia channel pls

I am bored

[tender shard]

I'd use a stream

imagine your config looks like this:

players:
  - mfnalex
  - verano

then you could turn that into a list of offlineplayers like this: (1 sec, gotta type)

[jagged monolith]

            for(String user : userDataFile.getConfigurationSection("Users.").getKeys(false)) {
                OfflinePlayer player = Bukkit.getOfflinePlayer(UUID.fromString(user));

                if(player.isOnline()) {
                    getUserDataMap().put(UUID.fromString(user), new ConcurrentHashMap<>());
                }
            }

This is an example from my own plugin.

[tender shard]

List<OfflinePlayer> players = getConfig().getStringList("players").stream()
        .map(Bukkit::getOfflinePlayer)
        .collect(Collectors.toList());

[rich pewter]

ok ty

ill try it tmrw gotta go sleep

[tender shard]

@sterile token why are you not in #bot-commands ?

[sterile token]

Im not playing ¿? Im lost, what did happened

[tender shard]

you are supposed to say "hi" in #bot-commands now

and then we play a trivia game

[sterile token]

If im not wrong when you compile, the comments are ignored

[buoyant viper]

i need it a Lot

[jagged monolith]

Yeah, i'd say the comments were ignored.

[sterile token]

So if you write any docs in the code, during compile they are just ignore

if im not wrong they will be always remove

[buoyant viper]

a compiled class file wont have comments/javadocs p sure

[sterile token]

yeah

[buoyant viper]

no matter what compiler u use

[sterile token]

You will have to generate the docs, from those comments

Its not posible

On IJ there is a tool for that

[buoyant viper]

https://maven.apache.org/plugins/maven-javadoc-plugin/usage.html

[sterile token]

No

If you are using maven they will be downloaded im not sure how that works sorry

[buoyant viper]

if u do it through maven i believe itll be a separate jar called like <artifactId>-<version>-sources.jar

[sterile token]

yeah

The problem is that you will have to upload it too

That are the main reason in my case of having my own remote maven repo for coding, so i just deploy my libraries there and i dont need to care about that type of things

[wet breach]

If you want people to be able to see the code after compiling. You need to attach sources

This will also leave the comments in place as well

[opaque scarab]

Anyone know of a good way to internally stop a task?

Yes I’m a beginner here

[sterile token]

If you are using BukkItRunnable, you can just call the cancel method

Also i will recommend using the spigot docs, for this type of questions

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[opaque scarab]

@sterile token Thanks, that worked!

[sterile token]

Your welcome, now you know you can alays use the docs for those questions

[quaint mantle]

hi

i am implementing a command right now. The command is called join and when a player uses the join command, it takes the name of the game as an argument, and it looks through a hashmap for that name and runs a runnable.

and passes the onCommand() method's arguments to the runnable.

here is what the code looks like.

games.get(gameName).run(sender, cmd, label, args);

i am getting a red underline on this code, how do i register a runnable that has parameters as well?

i was looking into consumers but they seem to only take one argument at most.

[buoyant viper]

assuming ur not using the Runnable for anything other than run(), make a class that has a method that takes in those parameters

like

public class YourClass
  public void theMethod(CommandSender sender, Command command, String label, String[] args) {
    // do stuff
  }
}```

[quaint mantle]

oh ok

then i could use like i show below, right?

YourClass name = new YourClass() {
  public void theMethod(CommandSender sender, Command command, String label, String[] args) {
    // do stuff
  }
};```

[buoyant viper]

yeah

[quaint mantle]

okay, just making sure since i have not really done a lot of java programming.

also, can i perhaps create another class that implements or extends Runnable?

[buoyant viper]

yeah

public class YourClass implements Runnable {
  @Override
  public void run() {
    // do stuff
  }
}```

Runnable is an interface last i rmemeber, so non-interfaces use implements keyword

?learnjava will probably help u on ur adventures too @quaint mantle

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.

[lavish hemlock]

There are BiConsumers but it's also possible to define your own functional interfaces.
Note that they're primarily intended for lambdas.

@FunctionalInterface
interface QuadConsumer<T1, T2, T3, T4> {
    void accept(T1 t1, T2 t2, T3 t3, T4 t4);
}

void myMethod(QuadConsumer<String, String, String, String> consumer) {
    consumer.accept("michael", "it's", "your", "birthday");
}

myMethod((s1, s2, s3, s4) => {
    // ...
});

I typed that on phone.
Kill me.

[quaint mantle]

Is it possible to modify something's texture ingame?
By sending packets or something like that?

[nova tiger]

hi i am looking for some plugin devs that can help me with a server dm me if you are interested you will get more info if you sent me

[lavish hemlock]

Via a plugin? Probably not. You'd want to have the server send a resource pack.

[quaint mantle]

Isn't there hidden packets that makes the java client change the texture?

[lavish hemlock]

Possibly. You can check wiki.vg to see.

[quaint mantle]

Ok thanks

[cold field]

OK. I give up plugin licensing is a mess

[lavish hemlock]

What's your problem

[nova tiger]

hi i am looking for some plugin devs that can help me with a server dm me if you are interested you will get more info if you sent me

[lavish hemlock]

Don't spam your advertisement

[nova tiger]

ok

@lavish hemlock i guess i found something that might help

[vale ember]

is there a way to avoid unchecked cast here? (projectile is of EntityType)

player.launchProjectile((Class<? extends Projectile>) projectile.getEntityClass());

[distant ridge]

How can I change the bot's "playing: whatever" or "watching: whatever" using DiscordSRV's API?

[ivory sleet]

It uses JDA iirc

So do it through JDA

[twin venture]

Hello friends , i have a bit of problem with json saving :
so the description is a single line , but its add each word in new list .. how i can fix that? or is this how its looks like?

iam not sure if iam doing something wrong .. :

desc + effects + i will also add requirments

[humble tulip]

@twin venture use a string for the description, not a String array of words

[quaint mantle]

Yeah youre using a list its going to implement each string on its own

[ivory sleet]

Well if you use gson, you could always define a typeadapter for it

[humble tulip]

projectile.getClass?

[vale ember]

it'll just give EntityType.class?

[humble tulip]

Wait what?

[vale ember]

projectile is EntityType

[humble tulip]

Ah

Where do you get the entity type from config or something?

[vale ember]

yeah i deserialize it

[humble tulip]

Well then deserialize it to the Class

[ivory sleet]

You can’t really avoid the unchecked cast then

[vale ember]

k guess ill just suppress it then

[humble tulip]

So store the projectile class somewhere in your code after deserializing

And check that it extends projectile.class

[twin venture]

its a list am i not wrong?
like this :

"hi this first perk, yes its amazing"

[humble tulip]

I think i understand what ur doing

[ivory sleet]

Thats a string

Of course you can define what a list is based of a string

But semantically

[humble tulip]

Do u want ',' to mean new line?

[ivory sleet]

Thats a string

[twin venture]

yes new line .

[humble tulip]

Ok well don't join the string[] with ', '

Just ' '

[twin venture]

i have tried to do it but didnt know how with json ..

ok thx i will try

[humble tulip]

It's not a json problem

[twin venture]

ok i will try today thx ..

[quaint mantle]

Is there a way I can just listen for all serverbound packets using protocolLib?

[worn tundra]

You could always do a for loop 🙄

[twin venture]

sorry you mean like this ?

yeah that fixed it

hi, how do i get the chat color code for the wool material?

[summer scroll]

What should I do If I want to create a playtime system but I can get the information about weekly/monthly playtime for the players.

[hazy parrot]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Statistic.html#PLAY_ONE_MINUTE i guess you can use this

or just manually calculate it

[buoyant viper]

i hate to say it but i think u need to check it against the Material class

and then obv some wools wont have a chat color

like Brown

[dry yacht]

Could you explain what you want to achieve in a bit more detail? What version are we talking about? Just "native" chat colors (&[a-f0-9klmnr]) or do you want to include "custom" hex colors?

[lavish hemlock]

You can approximate this to orange

Or, if you support hex colours, then yeah you can just use the hex colour for brown wool lol

[quaint mantle]

the version is 1.19.2 and i just wanna include all colors of wool.

but i have another problem right now.

so, i dont want players to be able to change anything in their inventory; the players should not be able to move any items, drop any items or place them or use them, i want every item in their inventories to remain in their original slots, how can i do it?

I tried the InventoryClickEvent but there does not seem to be a method called getPlayer() to get the Player object because I wanna check the player against a list of players to determine if the event should be cancelled for that player or not.

[tall dragon]

can any1 explain how to actually read server crash stack traces.

cuz all the threads get dumped but idk which one is actually causing issues

[river oracle]

getWhoClicked

No getPlayer for click event

[hazy parrot]

Can you send it?

[dry yacht]

You're going to have to accept a compromise on exactness then, as you cannot perfectly depict all wool colors using chat colors only.

[dry yacht]

IIRC, it was InventoryClickEvent#getWhoClicked, which is a HumanEntity, and needs to be checked against Players by the call of instanceof Player.

[dry yacht]

Whoops, didn't see that, xD:

How to handle multiple queries at once? I set up HikariCP connection pool, but after spamming 3-5 times query on command, it crashes.

[tardy delta]

i once made the jvm crash with worldedit :)

not closing statements too, very good

and x should start at 1

[eternal oxide]

don't close the connection when using Hikari

[tardy delta]

ah youre incrementing it before :/

[tardy delta]

doesnt it just return it then to the pool?

i always closed them and never had issues

[eternal oxide]

no it closes it and forces Hikari to open a new one

[tardy delta]

🤡

[formal bear]

So leave only execute()?

[ivory sleet]

no?

[eternal oxide]

Yes I believe so

I actually ran out of connections when testing it due to hikari having to open new connections all the time

ProxyConnection::close iirc from Hikari just lends the connection back to the HikariPool instance

ofc with proper locking mechanisms

[eternal oxide]

In my experience it didn;t, but I may be wrong

[ivory sleet]

Hmm, maybe the pool was configured in that way then

but by default hikari should abide by the object pool pattern

[formal bear]

        String INSERT = "INSERT INTO user_codes (code) VALUES ";

        for (String code: codes) INSERT += "('" + code + "'), ";

        INSERT = INSERT.substring(0, INSERT.length() - 2);

        PreparedStatement preparedStatement = mySQLDatabase.prepareStatement(INSERT);

        ProxyServer.getInstance().getScheduler().runAsync(instance, ()-> mySQLDatabase.executeQuery(preparedStatement));

    }``` After testing it with command /codes (prefix) (amount of codes)

It just stops responding

[eternal oxide]

Use batch for multiple inserts

[formal bear]

Instead of VALUES (x), (y), (z)?

[eternal oxide]

no you use PreparedStatement#addBatch

sec

[formal bear]

i understand

add inserts to batch

[eternal oxide]

https://github.com/ElgarL/GroupManager/blob/a6245f5ce36e136f564117e77851e45d4e3ea8f2/src/org/anjocaido/groupmanager/storage/CoreSQL.java#L236

[formal bear]

multiple insert queries into batch

[eternal oxide]

be sure to conn.setAutoCommit(false); and then enable it after

as when using batch you have to call commit yourself

It seems I do close my connection using Hikari

as I use a try with resources

[formal bear]

What about refreshing? For example UPDATE query?

[eternal oxide]

update can batch too

[formal bear]

Sure, thanks

And the last question, how to sync properly? For example once a second or smh? When players would start to query data with commands

For example 10 players will execute command at once

Just async for every query or

[eternal oxide]

you keep relevant data in memory and push to sql when changed. interval depending on how important the data is

[summer agate]

Is there anywhere I can find which java versions are compatible with which minecraft version? As far as I know mc 1.16 is up to java 16, and above requires java 17?

[remote swallow]

All versions below 1.16 are 8, 1.17 is 16 and all higher are 17

[summer agate]

would java 17 work with mc 1.16?

[remote swallow]

It would not

Actually

[warm mica]

You can even use Java 17 with Spigot 1.8 if the software and the plugins support it

[summer agate]

Not true, I am unable to run buildtools for 1.16 with java 17 installed

nope, a clean spigot server on 1.16.5 requires java 16 max to run (on linux at least which shouldn't be any different). Therefore you can't use java 17 for 1.16 plugins since java 16 doesn't know what to do with java 17 files

[ivory sleet]

Yeah iirc some libs prevents u from using too modern java versions

Server sidedly

[summer agate]

Guess I'll have to drop support for 1.16 then. Trying to use an api compiled on java 17

[ivory sleet]

An api,

?

Which api

[summer agate]

plotsquared

[ivory sleet]

Cant u use a version of that api which is compiled on j16?

[summer agate]

one of my codevelopers looked into it and the latest version on j16 was for max 1.17

[ivory sleet]

Hmm

In worst case you might have to write a proxy layer

[summer agate]

I was already going to drop 1.16 though when mc 1.20 comes out. Might as well do it earlier

[ivory sleet]

Ah alt

Alr

[summer agate]

only 3.3% of my users still use 1.16.5 and they can just keep using the old release

[ivory sleet]

Ye

So if you’re masochistic enough

You could work with abstractions

As by the means of having one module per version

(Or method+varhandles/reflection)

[summer agate]

Yeah no, I have already abstracted our code to be compatible with a forge (as in common code with an implementation for each) and I am never doing that stuff again if I can help it

[ivory sleet]

Its easier with spigot

Because you have the spigot api

And forge api consisting of events mostly (bit different)

[summer agate]

It will only be a small part of the plugin, so not going to bother

[ivory sleet]

Alr gl then

[summer agate]

Might as well drop 1.17 then since only 2.7% uses it

[vale ember]

is Bukkit's scheduler's delayed tasks reliable (cuz ticks per second isn't constant right?), or should i use java's executor for scheduling delayed tasks?

[summer agate]

Depends on what you want to use it for I suppose

[vale ember]

like ability cooldowns

[ivory sleet]

Is it bukkit bound?

[vale ember]

sometimes yes sometimes no

[summer agate]

You want server ticks for that, because that would mean that if the server lags, abilities are slowed too, so bukkit scheduler

[earnest socket]

I'm trying to make a cannon but I am having trouble making the cannonballs fire in the correct direction. I am currently summoning falling blocks. How should I go about doing this

[ivory sleet]

Well i don’t know if SES is much better

[earnest socket]

the direction of the cannonball should be the same as the armorstand's rotation that I use for the cannon btw

[ivory sleet]

Cuz I assume you want to jump back to the server thread when executing the tasks areg?

[vale ember]

yeah

[ivory sleet]

Go with bukkit scheduler

[vale ember]

k thanks

[ivory sleet]

Cuz with SES you will want to have another ES which is gonna cause sone latency already + a delegation back to the bukkit scheduler

[summer agate]

This is also a good idea yeah, just save when the last ability was used, and when someone tries to use it, check if the time since then is greater then the cooldown, if yes then they may use it

[vale ember]

so i need a set to be concurrent if i am modifying it from task run via BukkitRunnabel#runTaskLaterAsynchronously, right?

[earnest socket]

nvm I did it

[rotund ravine]

yes

just run a sync task

[ivory sleet]

ConcurrentHashMap.newKeySet() else

[vale ember]

is it better than Collections.synchronizedSet(new HashSet<>())?

[mighty aurora]

What would the best way to be to determine the air block just prior to the block determined by a raycast?

[eternal oxide]

subtract teh vector from the hit location

[ivory sleet]

Depends

Its faster

[tardy delta]

Collections.synchronizedSet just wraps the synchronized keyword around all interactions iirc

[ivory sleet]

Yep

[tardy delta]

should check impl but idk how to install ij on linux :/

app store broken

[ivory sleet]

No what you said is correct

[tardy delta]

[formal bear]

Why with app store??

[tardy delta]

idk how to install from tar.gz :/

[formal bear]

You can install Toolbox easily

https://download.jetbrains.com/toolbox/jetbrains-toolbox-1.27.2.13801.tar.gz

[tardy delta]

dont even know how to install from that

why cant they just give a deb file

[formal bear]

Just use dpkg

[remote swallow]

no

[formal bear]

cd jetbrains-toolbox-1.27.2.13801
sudo dpkg -i jetbrains-toolbox-something.deb```

[remote swallow]

if you mean about alex he changed his actual discord name

cafebabe doesnt/cant add a nick if it matches your current name

you should not use exceptions to control code flow

What should you do then

Panic and shutdown the server

I thought you meant like don't use exceptions and throw stuff

[remote swallow]

ahh lol

[worldly ingot]

Oh yeah, no that's horrible lol

Theoretically, you should be able to check if the statement is closed. Anywhere you're accepting a PreparedStatement you should have an open connection. You can't get a PreparedStatement instance without a connection

So if you really want to make that check, you can check if (preparedStatement.isClosed())

if I want to copy a world multiple times to have multiple versions of the same world which files do I need to delete to make sure that I don't get mc to think I'm trying to load the same world multiple times?

[remote swallow]

cant you just rename them and mc says its different

[torn shuttle]

no

worlds have an id file somewhere

if two of the same id try to load in mc locks the second one

[chrome beacon]

I believe the Spigot API uses the folder name

[remote swallow]

could be level.dat or session.lock

[chrome beacon]

so its fine

[torn shuttle]

mc still locks it

I already got the session.lock, I was wondering if there was more

trying to document this so I stop getting lost

[remote swallow]

might be in level.dat if its not session

yeah I have them, still annoying

[formal bear]

It shows me an error when there's no try n catch

[worldly ingot]

Well you're allowed to use try and catch. We're not telling you not to. We're saying that use of a try catch to handle the flow of logic is wrong. Your isNotConnected() method is an inappropriate use of try/catch

Your executeBatch() method can be changed to use PreparedStatement's isClosed() method instead, but I ultimately think that checking whether or not the statement is closed is a bit redundant given that you're only able to get a statement instance from an open connection

Regardless,

    public void executeBatch(PreparedStatement preparedStatement) {
        ProxyServer.getInstance().getLogger().info("[MYSQL] Checking if connected...");
//         if (isNotConnected()) return; // Replace this
        try {
            // With this
            if (preparedStatement.isClosed() {
                return;
            }
            // ^^^

            ProxyServer.getInstance().getLogger().info("[MYSQL] Trying to send data...");
            preparedStatement.executeBatch();
            preparedStatement.close();

[dry yacht]

Btw, just curious, is this still an active issue? I don't know how much a version-independent and color-accurate solution is of importance to you, but: It wouldn't be a big deal to get the current server version, go to mojang's version manifest and find the corresponding client.jar url, extract the assets folder, query all block PNG files, calculate their average RGB color and store this information into a JSON-based table, which you can then load when the plugin loads. You version supports hex-colors, and that would most definitely give you the most accurate results available, for all blocks - not only for wool.

Otherwise, the quick and easy way would just be a lookup-table implemented as a switch-case block, where you match materials to chat-colors, obviously.

Item name not changing on checks

[spring pike]

Hello, I have a pvp server for me and my friends, and, when fighting, damage sometimes gets dealt withtout "cooldown", even though there should be 10(?) ticks of invincibility when a player gets damage. What could be causing this? I have no plugins on my server that mess with damage events. I hope it's possible to see in the video

[remote swallow]

isnt that just default minecraft

[spring pike]

default?

[dire marsh]

what server version

[spring pike]

the server is 1.8.9, but I play on 1.7.10 with viarewind

[dire marsh]

not sure then

we've experienced something similar on newer versions, might just be an mc thing

also I believe it's an entire 20 ticks of invincibility

[spring pike]

1 second?

I play lots of pvp, and I'm pretty sure it's .5 seconds

or at least something very close to that

[remote swallow]

might be a via rewind thing

[spring pike]

I was also thinking of that, I think i'll remove it and try it out

[dry yacht]

Is it tho, at such an old version? I still remember how clickspeed was always a huge topic, which wouldn't make sense with cooldowns as huge as 500ms.

[dire marsh]

checked 1.19 src and it's 20, could be different for 1.7/1.8 though, haven't played those for ages

[tender shard]

lmao when 1.8 isn't old enough already, so yuo install viarewind so you can use even older versions lmao

[spring pike]

preference

[spring pike]

I directly compared it to the damage of a server at the same version, it's way slower than on my server

[remote swallow]

what year was 1.8?

[spring pike]

2013 I think

close to 10 years lol

[remote swallow]

?1.8

[undone axle]

https://howoldisminecraft188.today/

[dire marsh]

aha it's / 2

so it's the same on all versions

[dry yacht]

Yeah, because there have always been ways to artificially increase the hit delay, and many server owners did that to improve the game experience for non-tryharders, lol.

[dry yacht]

Did that help? Otherwise, you could try overriding it programmatically.

[spring pike]

Didn't try it yet, hold on

[crystal palm]

heya!
im looking to store information inside of an item. when someone will right/left click while holding it, itll run a command.
will persistendatacontainers work? when the item is first made, ill give it some data and check for it when the player tries to interact

[spring pike]

didnt work.

[formal bear]

I'm going insane, prepareStatement's function stops after few runs https://paste.md-5.net/royofolise.md

[tender shard]

yes, pdc will work

[crystal palm]

alright, thank you!

[dry yacht]

Looks like this is manipulating the delay you're after, although I haven't tested it myself: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#setMaximumNoDamageTicks(int)

You could just set a desired number of ticks on a player when they join, which will then be active until they leave (AFAIK), and thus in effect all the time.

[spring pike]

thanks, I'll try it. Even after deleting all my plugins except for viarewind (because i tested it already) and multiverse it didnt get fixed, so I'll have a look at the multiverse config too if your method doesn't work.

[dry yacht]

That suggests that nobody else alters this delay, and it might just be what 1.8 actually defaults to (which I'd also remember it as, delays have been introduced in 1.9). You could also print out the getter of that delay onJoin, to see for yourself what it defaults to.

[eternal oxide]

A jar added to your resources folder will not be loaded by the classLoader

[dry yacht]

What other plugin does this work for? I'd actually be curious about that.

[remote swallow]

shouldnt you be shading stuff you want to run as a plugin

or add the jar to the class loader

[eternal oxide]

dependencies are not resources folder

[spring pike]

seems like you're right, and servers actually use methods to alter it. I set max no damage ticks for players to 20 when they join, sadly no results. Thanks for the help though

[dry yacht]

But you understand why we think that it doesn't work that way, right? Yes, if the plugin-loader has been instructed to load jars from resources/ into the path, then sure, it would work. But what loader does this?

Usually, you either shade your dependencies into your plugin or specify them in the plugin.yml for the server to provide them (which I never did, due to the fear of the server not doing it's job properly).

[tender shard]

ugh never do that

[dry yacht]

Did you print out the old value, as I suggested above? This could assure you that your code actually ran and took effect.

[tender shard]

why would you ever want to use scope system?

https://blog.jeff-media.com/manually-installing-jar-files-to-your-local-maven-repository/

[eternal oxide]

you remove it from your resources and shade properly

[spring pike]

I printed it out, it says 20, one line after that I set it to 20 too.

[tender shard]

did you write the api yourself? is it a maven project too?

[spring pike]

and this is on the same event that changes join messages so it works 100%

[tender shard]

then just mvn install the api project

after that, add it as dependency to the other plugin, set the scope to "compile" and shade it

second headline https://blog.jeff-media.com/common-maven-questions/

np 😄

[dry yacht]

This is so weird... Feels like another event subscriber alters it later on, but you said that you removed all other plugins already. Would you mind sharing your server jar with me, so I could give it a quick try locally? I'd actually be interested in what's keeping this setting from being applied.

[spring pike]

Sorry, I don't think I can do that. You'd have to download the whole server too because some plugins don't work without each other and so on... I'll try finding another way

[twilit roost]

bump 2x

[dry yacht]

Just meant the server.jar, to make sure we're on the same version. But I think you mentioned 1.8.8, so I'm just going to set up one of those.

[remote swallow]

paper probably still host 1.8 paperclip jars

[spring pike]

ohh, sure, here you go. PaperSpigot though, I hope I'm not on the wrong discord

[dry yacht]

Thanks! :). This is a general minecraft-server thing, I'd say it does not at all matter which "flavor" it is.

[spring pike]

Another strange thing I noticed tho, this only occurs when another player attacks me, AND when he's crit damaging me

as in the video

therefore it might be hard to test this locally

[dry yacht]

Server returned HTTP response code: 403 for URL: https://s3.amazonaws.com/Minecraft.Download/versions/1.8.8/minecraft_server.1.8.8.jar, alrighty, going back to my 1.8.8 spigot jar, xDD. Shouldn't make any difference anyways.

[spring pike]

nice lol

[tender shard]

update buildtools

[dry yacht]

Didn't build anything myself tho, wonder how @spring pike got it running, xD.

[spring pike]

i don't even know

it was 6 months ago and in my whole history of making servers I never had anything to do with buildtools

[remote swallow]

if you ran a spigot server you would have

or did you use get bukkit

[dry yacht]

Okay, there's actually always a delay on my server, so it sadly seems like I really cannot reproduce this issue.

[tender shard]

just shade it. set the scope to "compile" and add the maven-shade-plugin including the confiuration. then just do mvn package and you'll have a .jar with the API shaded in

[spring pike]

I downloaded the paper spigot jar man im confused

[remote swallow]

what is paper spigot

[tender shard]

yes

[remote swallow]

is that some fork of paper

[tender shard]

it's a spoon of paper

[remote swallow]

make sense

[spring pike]

pretty sure it's archived here https://papermc.io/downloads

[remote swallow]

oh thats just paper

[eternal oxide]

?fork

[undone axle]

SpigotMC maintains the Spigot server. If you are using a fork of Spigot (such as Paper, Airplane, Purpur, or other derivative works), you should seek support in the appropriate Discord servers.

[dry yacht]

Sorry, I completely missed this video! Seems like a player can double-hit when critting, which I can also reproduce. This seems to be desired behaviour on that version tho.

[spring pike]

my game client says PaperSpigot 1.8.8 when viewing my server in the list

[tender shard]

huh paper removed their quiz for old versions

[remote swallow]

guess they used paper spigot as a brand before

[spring pike]

Do you have any idea how to remove the "double crit hits"?

[tender shard]

new spigot logo confirmed

[remote swallow]

what is that

[tender shard]

duh obviously that is a siphon for kitchen sink with flexible drain hose - 100% waterproof - tubular siphon with two appliance connections + connection seals.

[dry yacht]

Hmm, I think the only way to really find out how (as just googling it didn't yield much for me) is to have a look through the hit logic in NMS. I don't have a de-obfuscated jar laying around, give me a quick second, I'll have a look at the topic and get back to you.

[remote swallow]

oh its a u bend pipe

wheres your something trap

[tender shard]

something trap?

[remote swallow]

theres a trap thats meant to be on them i thought

come on discord

[tender shard]

hm I am not expert when it comes to spigots and siphons. Maybe ask md_5 about it

[spring pike]

NMS, the three letters I hoped I'd never come across again

[remote swallow]

these

there could also be a u bend pipe

[tender shard]

can't you just check whether it's a crit hit in EntityDamageByEntityEvent and then do a cooldown

[dry yacht]

A trap for what, tho? The stinky gases are blocked due to the air-tight seal the water in the u-bend creates.

[tender shard]

no clue what this is for, but I love it

[dry yacht]

Yeah, that would be the easiest solution, I guess.

[spring pike]

I already put a cooldown, even without critting

[remote swallow]

i think thats a replacement for a ubend

[dry yacht]

NMS is the foundation of everything we modders work on, no way to avoid it. It's your friend, obfuscation just makes it a clusterfuck to work with.

[tender shard]

but why would anyway block the stinky gases instead of enjoying them freely?

[dry yacht]

Didn't work?

[spring pike]

nope 😦

[dry yacht]

Could you show an excerpt of the event you wrote? Did you cancel the event within the cooldown period?

[spring pike]

I put it into the same event that reduces overall attack damage, so don't worry about the other stuff

and no i didnt

[dry yacht]

That's not really what I meant. Going to give you an example in a second.

[remote swallow]

== for enums

[tender shard]

I'd create a cooldown class (https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/data/Cooldown.java) and then manually cancel the event if a player still has cooldown

[spring pike]

sure

[spring pike]

I'll optimize it in a second

[tender shard]

I'd do it like this basically

    private final Cooldown cooldown = new Cooldown();

    @EventHandler
    public void onCritHit(EntityDamageByEntityEvent event) {
        if(cooldown.hasCooldown(event.getEntity())) {
            event.setCancelled(true);
            return;
        }
        cooldown.setCooldown(event.getEntity(), 500, TimeUnit.MILLISECONDS);
    }

ofc also check the damage cause and the damage amount and stuff

[spring pike]

noted, thanks

[tender shard]

(the Cooldown class is what I sent above in the github link)

[spring pike]

oh didn't see it, appreciated

[remote swallow]

alex i have a question

[tender shard]

NO

[remote swallow]

sad

[tender shard]

well ok

[spring pike]

I'll just wait for BlvckBytes answer

[remote swallow]

can i have a like 2gb server on ur ptero because everytime i attempt to run mc, a server and intellij my computer just dies

[dry yacht]

I really don't get why the event has no API for checking for critical damage... I had to first research the requirements of critical hits before I could get to actually thinking about the solution itself, haha

[tender shard]

ok. do you have admin perms already?

[remote swallow]

yeah

[tender shard]

kk

then go ahead

[remote swallow]

thanks

[tender shard]

np

[remote swallow]

ill give you a gregg

want me to name it anything specific

[tender shard]

greggs 🤤

[twin venture]

Ideas for perk event system

[tender shard]

i dont care

[remote swallow]

ebics whor'e server it is

damn you get a double 0 ip

[tender shard]

wdym

10.0.0.X?

that's private IPs

[remote swallow]

yeah

oh

also massive tragedy

[tender shard]

that's the bridge vlan on the proxmox host

[remote swallow]

i cant have port 69696

[tender shard]

no it only goes up to 65535 or sth lol

[remote swallow]

it only lets me pick 300number ports

so 30069 we go

[tender shard]

nice

[remote swallow]

want me to add a cpu limit, also do i add a swap size

[tender shard]

swap is only needed if you don't use enough ram

cpu limit, no

[remote swallow]

ptero seems cool tbh

[tender shard]

the server has enough free ram, just use whatever amount you like lol

[twin venture]

oma how much do you pay for that?

[remote swallow]

ill limit myself to like 8 or 6gb

you pick

[twin venture]

if i have something like that i will make the best server i can xd

[tender shard]

that's just a VM in proxmox. here's the actual host

and it costs roughly 100€ + 19% VAT per month

[tender shard]

6 should be enough lol

if it's not enough, you can still raise it later

[twin venture]

can you give me the link?

[remote swallow]

theres something weird ive noticed that i do

if im specifying ram for servers i do 1024 x gb size

and use that mb

[tender shard]

https://www.hetzner.com/dedicated-rootserver/matrix-ax AX101

[twin venture]

is the host avillable at France or germany?

oh its hetzner

[tender shard]

germany and finland

[twin venture]

i know them

[dry yacht]

Cannot seem to get that event to trigger twice, can you give it a shot? Here's the test code: https://paste.md-5.net/royimoxeta.java

Check your logs for the cancel message, I cannot get it to show up, and the event also only triggers once in general.

[dry yacht]

Maybe this is some sort of internal bug? I really lost connection to 1.8.8, as it has been ages since I actively worked with it.

[remote swallow]

how much disk space do i get

[spring pike]

I'll test it, takes a minute or two

[tender shard]

there's 418G left so choose yourself

[dry yacht]

Take your time, I'm not in a hurry! :)

[remote swallow]

immediate thought is 50gb, then i think what will i ever use that would need that ill use like 20gb lol

[twin venture]

he problem i must pay a setup fee . :

[glossy venture]

im so fucking confused how the fuck does this work
what the hell

[dry yacht]

Those 32 cores seem like they could use some more usage, :).

[tender shard]

yeah epic, do some heavy worldedit stuff

[runic island]

How do i make theese dependencies work?

[tender shard]

did you add the spigot reopsitory?

repository*

also why would you add all those api versions

[twin venture]

#1060646223075360829 anyone made a perk system can give me ideas xd?

[tender shard]

you should use one spigot-api, not a hundred

[runic island]

I want my plugin to work on other versions

[tender shard]

that has nothing to do with that

use the lowest api version you wanna support

[remote swallow]

if you dont use nms do the above

[tender shard]

if you want to do 1.16.5+ then use spigot-api 1.16.5

[twilit roost]

I have Integer x.
I have some Strings whose are Negative Spaced Characters.
I want to transfer that Integer, into biggest possible combination of those Strings

for example:

"pseudo code"
Integer xToBackspace = 20;

String outputed = "{NEG16}{NEG4}";

I somehow want to create a function, that will generate that outputed
Heres my current try:
https://paste.md-5.net/enamuyeren.java
Use case:
https://paste.md-5.net/yenobukito.cs

[dry yacht]

If you're missing a version, you could always install it into your local maven repository by running build-tools for that revision.

[tender shard]

but that's just the api, it's in the spigot maven repo

[spring pike]

@dry yacht I read through your code, 2 things. .#isOnGround() is deprecated, and the HashMap may be final. Should I ignore this?

[dry yacht]

I know, I'm just saying that, because I often just don't even bother with specifying the spigot repo.

[tender shard]

there's no good alternative to isOnGround, just use it

and whether the map is final or not doesnt matter

[spring pike]

oko

k

[tender shard]

true lol

[runic island]

should i use snapshots or releases? And if releases how should the dependencies look

[humble tulip]

Uhh

[tender shard]

thankfully github copilot always adds the repo for me

[humble tulip]

Wbay are u doing?

[remote swallow]

rooster.jeff-media.com is redirecting to public ip right?

[twilit roost]

imma explain it to u in dms?

[tender shard]

you can just use jeff-media.com:30069

[remote swallow]

thanks

[humble tulip]

Sure

[dry yacht]

Yes, ignore this. Sadly, the API gods have not provided us mortals with a better interface for checking critical damage yet.

[spring pike]

sue them

[glossy venture]

dude what how the fuck does this work please tell me

[dry yacht]

That question just hurts my brain, tbh, xD

[dry yacht]

Like, waaaay too little context.

[glossy venture]

its on a thread

its printing, calling a function on the same fucking thread, which should print something, but it doesnt
it just printing the first thing

and other functionality in the stupid function doesnt work either

im so confused

[dry yacht]

Would be great to know what worker is and how it's set up.

[undone axle]

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

[glossy venture]

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

this is the whole thing

its just a thread

not that complicated

[dry yacht]

Btw, seems unrelated, but sometimes the issue with printing can be unflushed buffers too. Like, you print something but it hasn't yet been flushed to the output device. But in this case, this is not an issue, as you print over and over again, and println internally flushes, iirc.

[dry yacht]

1 sec

[chrome beacon]

Make sure you're using the right worker instance

[glossy venture]

i had it as a not static class first

but i thought that might be broken or smth

so i made it use di

with a static class

[quaint mantle]

anyone know how to make github actions work with buildtools ?

[glossy venture]

for UpdaterThread

[dry yacht]

Please tell us the specific workflow you want to implement using github actions, and what's the actual issue you're facing.

[spring pike]

@dry yacht thanks so much man, it works. You're a livesaver

[quaint mantle]

Well as you know buildTools does stuff on maven local and my github action compiles and releases the jar as a latest release

[tender shard]

do you already have a workflow file?

[chrome beacon]

https://github.com/SpraxDev/Action-SpigotMC

[dry yacht]

It works? Holy moly, I never thought that it would, lol. What a weird case! I'm very happy to hear that I could help you tho, :)).

[dry yacht]

Yeah, but what do you need from build-tools? Are you implementing against any NMS-APIs? Because the spigot APIs are available on a public repo.

[quaint mantle]

Thanks

[spring pike]

just removed the prints, the console gets clustered really quickly 😄

[tardy delta]

im wondering if i like make it method synchronized that changes a field x, will that synchronize on the whole object and prevent modifications on other fields too for threads that dont have the lock acquired?

[dry yacht]

Oh yeah, of course, they were just meant as a means to quickly debug your local situation, xD. You can now also make the map final, btw, as I forgot to do that and it's good practise (as it will never be reassigned during it's lifetime).

[copper scaffold]

Is it possible to disable the chest open animation?

[tardy delta]

or is there a dif bwteen synchronized (this) and synchronized in a method declaration

hmm that will probably allow only one thread to enter that method and wont lock on the whole object

sometimes im asking weird questions

[dry yacht]

Very likely locks the whole object, especially if the target member is not another allocation in memory itself. But I don't think that Java in general locks on such a granular level automatically, without you specifically instructing it to.

[wet tapir]

I'm sorry idk what to actually do here.
I'm trying to convert my pack to a plugin but people keep acting really weird...
Like as if I'm not even allowed to be around them or learn how to do it.

[tardy delta]

hmm

[dry yacht]

Huh? That sounds mean, :(. By pack you mean resource-pack?

[onyx fjord]

how do I set up gh actions so they can compile something with spigot remapped?

[wet tapir]

Yea I make optifine packs that require cit files

[chrome beacon]

https://github.com/SpraxDev/Action-SpigotMC

[quaint mantle]

remapped: false # Optional

[wet tapir]

@dry yacht I been working on them for years now

[tardy delta]

id think that this locks the whole object java void setI(int i) { synchronized(this) { this.i = i; } }

and synchronized in the header only prevents two threads from calling setI at the same time

[onyx fjord]

thx olivo

[dry yacht]

Optifine packs, hmm... Sadly have absolutely no experience with that topic, but I'm sure somebody might be able to pick up on it in this channel.

[zealous scroll]

Is there a way I can remove a set of entities upon server unload (reload/stop)? So far, entities have to be in loaded chunks to be removed. I've tried loading the chunks, removing them, then unloading the chunks but that doesn't seem to fix the issue. I don't really want to keep the chunks loaded all the time to save memory because my plugin uses these entities heavily all around the world.

[dry yacht]

Of course it does, as the semantics suggest.

[tardy delta]

ye never actually used it before

[dry yacht]

Same, just a gut feeling, lol.

[dry yacht]

Well, I did, but I never properly read up on it's inner workings.

[tardy delta]

once wrote a chat app that uses Object#notify and Object#wait for sending and receiving messages :/

[wet tapir]

@dry yacht
As far as I understand. I'm able to convert my Json models to a yem or something to load into a plugin
I seen it in the quality armory plugin
But idk how to make my own plugin that's the issue

[chrome beacon]

All you do is send a resource pack

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#setResourcePack(java.lang.String,byte[],java.lang.String,boolean)

[proven surge]

hi

i have problem

[wet tapir]

@chrome beacon yea but
I want to make people stuff
Not just for my self so I was gonna start making pack plugins

[dry yacht]

Something along the lines of a method which removes all entities from a given world based on a <Entity, Boolean> predicate when called? Or do you already have a handle on these entities because you created them earlier?

[zealous scroll]

I already have a handle on them, but I do remove them based on a predicate

        for (world in Bukkit.getWorlds()) {
            for (entity in world.entities) {
                if (EntityUtils.hasFlag(entity, EntityFlag.REMOVE_ON_SHUTDOWN)) {
                    entity.remove()
                }
            }
        }

[chrome beacon]

I don't understand the problem?

[proven surge]

I'm having a problem adding lands

[twin venture]

what's the problem?

[proven surge]

If I want to give someone trust on lands

[river oracle]

Uhm you are probably in the wrong place for this. Ask in the discord of the developer of your target plugin also since your not a dev #help-server

You are always best off asking the developer though

[dry yacht]

Well, that's not what I meant by having a handle on them. You're still querying the whole server. I meant something along the lines of you having spawned them earlier, kept them in a list or map and now want to remove them.

Okay, and your issue is (probably) that the entities you want to remove are not showing up in your loops because their containing chunk got unloaded, right?

Just trying to understand your problem first.

[tardy delta]

damn

[zealous scroll]

That would probably be the case, yeah

Would you suggest I save them in a collection to later on query it and remove these entities in a loop instead of fetching all of the world's entities?

[wet tapir]

Well.
I believe that I should attempt to learn how to do this.
But I'm scared because there is already a lotta work I gotta make but I'm still willing to try @chrome beacon

[chrome beacon]

So why do you need to make a plugin?

And what should that plugin do

[tardy delta]

how is it still not 1000 or 999 whatever

[dry yacht]

How do you assign that entity flag to entities? Or rather when?

[tardy delta]

ah wait i print the i before the threads are done

[dry yacht]

Was just about to say this, but I thought that executor.shutdown() might join on these threads. Guess it didn't.

[tardy delta]

ok returns 1000 when doing awaitTermination

[zealous scroll]

I assign the flag upon entity creation. It's just a metadata flag

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

[tardy delta]

oh i thought ExecutorService#join was a thing

oh this also works

not two times shutdown

[dry yacht]

Okay, that's what I thought. Then I'd say that it would be best to keep a local variable in the class which creates entities that keeps track of them, for later removal.

That collection should probably only be weakly referencing it's items, as I guess one of your spawned entities can die and be garbage collected later on, and you might run the risk of creating a memory-leak otherwise.

I'm not sure how bukkit internally handles entities, and if Entity#remove throws if that entity has been unloaded by the server. Your main issue is that you do not want to get as low level as modifying world NBT data yourself, which the entity should know it's exact place in and be able to remove itself.

I'd advise you to try the collection approach and see if you encounter any further errors.

[dry yacht]

What else, three times?

[tardy delta]

one maybe ,-,

what A ThreadPoolExecutor will automatically adjust the pool size (see getPoolSize) according to the bounds set by corePoolSize (see getCorePoolSize) and maximumPoolSize (see getMaximumPoolSize). When a new task is submitted in method execute(Runnable), if fewer than corePoolSize threads are running, a new thread is created to handle the request, even if other worker threads are idle.

[spring pike]

@dry yacht it turns out your method of fixing the critical double hits worked, but only kinda. Sometimes my friend couldn't hit me at all for a second, sometimes the old issue came through again.... idk what to do now

[quartz goblet]

Does anyone know why I would be getting "CraftWorld cannot be resolved to a type?" Like is the craftbukkit stuff not in the api? When I take it into luyten my api has it

[tardy delta]

no

hhave to use spigot artifact instead of spigot-api

[dry yacht]

That's why I left those debug prints in there, so you could check it's behaviour and check for when it actually cancels the event and when it detects critical damage, to maybe find out where it misbehaves.

[tardy delta]

well actually wondering if CraftWorld is nms or not

just craftbukkit ig

[quartz goblet]

what is spigot artifact?

[tardy delta]

are you using maven or gradle?

[spring pike]

I left them in there at first, I just didn't notice the inconsistencies because we only tested it for a few seconds

[quartz goblet]

maven

[zealous scroll]

a WeakReference collection seems to have fixed the issue, thank you. It appears I was attempting to get all loaded entities in the world and removing them but I, of course, wouldn't be able to remove those that were unloaded

[tardy delta]

just change 'spigot-api' in the dependency in your pom.xml to spigot

[quartz goblet]

thanks ill try that

[dry yacht]

Great! It's best to keep a "pointer" (weak ref) to your own created entity, rather than to query all chunks of all worlds (a ton!) to find them later on, based on some flags. You just cut out the middleman.

[dry yacht]

Add them back and check for cancellations which shouldn't apply, for example. I cannot really debug that system, as I cannot reproduce it locally.

[spring pike]

It's hard to find out which cancellations shouldn't apply, since there are many instances of critical damage when fighting

[dry yacht]

I know, welcome to the world of debugging, :p! It does seem to me like this is a bug in general, something weird with the minecraft-server version 1.8.8. You could try reducing the 500ms to like, idk, 200ms (four ticks), if the delays seem to be too long when in quick combat.

[static hollow]

hello,
I've wrote this class for Bukkit's Location serialization:
https://pastebin.com/vDDR1WUs

And using it like this:

Gson gson = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create();

List<JsonElement> countriesToWrite = new ArrayList<>();
for (Country country : countries)
{
    countriesToWrite.add(gson.toJsonTree(country, Country.class));
}

try (FileWriter writer = new FileWriter(playerFile))
{
    gson.toJson(countriesToWrite, new TypeToken<List<JsonElement>>()
    {
    }.getType(), writer);
} catch (IOException e)
{
    e.printStackTrace();
}

Country class don't have any Location at all, but Plot (and there are plots in country.plots) have this:

@JsonAdapter(LocationSerializer.class)
@Expose
@Getter
@Setter
private Location corner1;

@JsonAdapter(LocationSerializer.class)
@Expose
@Getter
@Setter
private Location corner2;

The problem is, that when I'm using the code #2 for saving json, it gives me stackoverflow error (recursion). Why? :/

[tardy delta]

why excludeFieldsWithoutExposeAnnotation()

[static hollow]

why not? I don't want them

[tardy delta]

make them transient

at what line does the stackoverflow occur?

[static hollow]

it says 11 and 25

[hazy parrot]

And what are those lines

[static hollow]

Oh, right, you don't see it in pastebin. Im sorry

As i remember, 11 was just a class name and everything, and 25 was setting z in serialize

In plugin.yml

[river oracle]

whatever version of the api you are coding with

[chrome beacon]

1.13

[runic island]

Well whenever i put it as anything else than the version im using on the server it doesn't load. And i want one plugin file to work with all versions

[river oracle]

you sure about that

cuz thats not how api-version works

[runic island]

I just get this error but the 1.12 changes to whatever i enter:

[chrome beacon]

It should be 1.13

[river oracle]

^

[runic island]

And then it will work 1.13+?

[river oracle]

wasn't api-version added in 1.13 ofc it would make sense it doesn't work with anything below that

if you are using 1.12 api don't bother adding it I'm pretty sure legacy mode will be activated

[chrome beacon]

Any version. Versions below 1.13 doesn't read the api-version setting in the plugin.yml

[remote swallow]

yeah api version was added in 1.13

[runic island]

I coded it using 1.19 but im almost not using any spigot api stuff at all other than simple commands and send chat messages

[river oracle]

then it works for everything 1.19+

adding api-version to config as 1.19

[runic island]

Yeah

I get this error now. Do i need to change the java version im using in intellij?

/DiscordServerStatus has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

[chrome beacon]

Yes you need to use Java 8

[runic island]

Okay

[runic island]

Is it a maven setting or intellij setting?

[remote swallow]

both technically

change the sdk in intellij, and compile version in pom.xml

[runic island]

Change the 11's to 8?

[remote swallow]

yeah

[runic island]

I changed the 11 to 8 and i have this in the project structure but i still get the same error

[hazy parrot]

1.8 iirc, not 8

[runic island]

In pom.xml?

[hazy parrot]

Yes

Im still getting the same error :/

[dry yacht]

https://stackoverflow.com/questions/53642402/why-do-i-see-open-jdk-1-8-instead-of-java-8

I always thought that 1.x === x, as they at some point in time started to take the minor version number and use it as a standalone version number.

[dry yacht]

55 refers to Java 11, so you're still compiling with 11.

[dry yacht]

Can you share your whole pom.xml in it's current state please?

[runic island]

Ok

[chrome beacon]

They dropped the 1. In Java 9 and above

[runic island]

Just paste it in or should i use some website?

[dry yacht]

?paste

[undone axle]

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

[dry yacht]

But specifying Java 1.8 as 8 will be fine with all java compilers.

[runic island]

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

[dry yacht]

Did you run clean before package once? And please make sure that you actually overwrite the file in your plugins/ folder, as that's often the issue too.

[runic island]

I don't understand the first thing you said but the file has changed because the time last changed is correct

[dry yacht]

Well, how do you usually initialize compilation? I use IntelliJ's maven window.

[runic island]

I just press install

[dry yacht]

Then press clean first, then do your usual thing

Maven tries to cache compilation units and strives to compile as little as necessary, so it may be stuck at not re-compiling the necessary parts because it hasn't been noticed of the version-change properly. You can force a complete rebuild by running clean first.

[runic island]

It worked! Thanks alot for your help

[dry yacht]

Happy to hear! :).

Damn, I forgot to uncheck that. I'm sure it'll bother me a million times with "do you want to update" now, :(.

[tender shard]

lol why would you evern uncheck that

[eternal night]

Living dangerously

[dry yacht]

Because I don't want to update to Ventura, as I always postpone updates as long as possible to let them mature further. Doesn't seem like they have fixed anything I'm interested in anyways.
