[wet breach]

well you would have to specify the variable at the top of the class or outside of a method

easier if its at the top to keep track of class variables

[ionic thicket]

oke now i dont have errors

how do I access that in the other class now? do i need to create an instance?

[wet breach]

got to keep up with the features

[remote swallow]

ive looked at the cc list so many times idk how i never noticed that

[dry yacht]

I read about how booleans are encoded to integers (shouldn't it be bytes tho?) and how they store true as 1 and false as 0. But thats encoding, when decoding, == 0 is false should still hold, as I've read in OpenJDK's source. Am I missing the catch there?

What equals returns is completely up to the implementation of the object you're calling it on. The default implementation is a memory address comparison (==), so no, this cannot be said that generically.

[wet breach]

almost everything in Java is backed by Integer

[quiet ice]

ints, shorts, chars, bytes and booleans are ints

[wet breach]

.equals() does not do a reference equality check, you might be referring to === instead?

where it does both

[quiet ice]

Yeah, == 0 still holds

But for boolean arrays != 1 should also hold according to the JVMS - but I strongly doubt so

[dry yacht]

It does by default, because you should override it yourself. How do you think that Java knows what fields of the object to compare? It does not by default just compare all fields, that would not be desired behavior.

[quiet ice]

More specifically JVMS 19§2.3.4 "The boolean Type"

[dry yacht]

I doubt that too because it would add a unnecessary limitation and maybe even break some edge cases which rely on the fact that all non-zero numbers evaluate to true. As I've said once, I think this is a legacy "convention" due to the ease of checking a register for all zero bits instead of against the numeric value one.

[quiet ice]

In my case it is

    public boolean equals(Object obj) {
        return (this == obj);
    }

Not sure why the brackets are there.

[quiet ice]

It's because for arrays it makes sense to pack the booleans - While oracle doesn't do it doesn't mean that other JVMs don't do it so I think this exists in order to force compliance of that being possible across all JVMs

[dry yacht]

Yep, that's the default implementation that you should learn about when learning about Java. Of course it is, everything else would be insanity. .equals() is just a convenient interface, but not meant as an automatic equality detector

[dry yacht]

Oh, others actually do that? I thought java never packs booleans. Now I get what you mean by the catch you were talking about! :)

[quiet ice]

There is definitely one implementation out there that does it

However it isn't being freely advertised as you can't really sell non-hotspot JVMs if you want to work with Oracle

Eclipse OpenJ9 is a perfect example for that

[undone spindle]

?tab-complete

to bad lol

[dry yacht]

But I guess that the average programmer won't have control on such a low level anyways. The original question for me was more of a "what happens if you cast an integer to a boolean". In that case, the only sensible thing to do is to accept everything non-zero as true. Of course, if you pack bits, you have no more space for any other values besides zero and one. But you're not going to reinterpret an integer as a byte[], 99% of the time.

[quiet ice]

In java world you cannot cast ints to booleans in any way I believe

It's only something in JVM world, at which point true and false does not exist (hell boolean only exists in descriptors but not anywhere else)

[remote swallow]

create an on tab complete method and extend TabExecutor, switch the args.length and then return a StringUtil.copyPartialMatches with the results you want to show

ill paste an example rq

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

something like that

args.length starts at 1, args[] starts at 0

[dry yacht]

Tbh, I have no idea, I just remember that the integer value implementation had a booleanValue() method, see: https://paste.md-5.net/edokigexaf.cs

But then again, I have no idea how the JVM works and I just way too often assume things about it that I know of other languages.

[wet breach]

ah right, default implementation is that if nothing overrides that is correct. However in regards to Java API, stuff does override that typically

and therefore that caveat is only for custom objects

which is what should be noted

[quiet ice]

From where the hell did you bring that from the depths of hell?

[dry yacht]

Not really, I have had countless "professional codebases" which either didn't override that method on some classes at all, or did a bad job at doing to. To just tell people that .equals() checks contents is plain wrong and may cause a lot of headaches, as it's completely depending on what the person who wrote the class decided to implement.

[wet breach]

are these professional codebases java api?

[dry yacht]

Straight out of /Users/blvckbytes/Downloads/jdk-687fd7c7986d/src/share/classes/com/sun/tools/jdi, haha :,D. I literally just grepped around, as I am completely lost in that codebase.

[dry yacht]

Ah, right, we're talking about the Java-API, I missed that.

[quiet ice]

Chances are you aint going to be able to use JDI

Whatever JDI even is

[wet breach]

it should be noted that sun packages are proprietary and thus JVM specific

IE, openJDK won't have it

[quiet ice]

Ah, debugging

[quiet ice]

Eh chances are they have

[wet breach]

OpenJDK does not contain proprietary code

which is basically the sun packages

[quiet ice]

https://github.com/openjdk/jdk/blob/master/src/jdk.jdi/share/classes/com/sun/jdi/IntegerValue.java

I challange your opinion

[wet breach]

its not my opinion

OpenJDK contains no proprietary code

[quiet ice]

Well yeah, but as it turns out there is no proprietary code in OpenJDK

[wet breach]

there may be some things in the sun packages that were deemed allowed

[quiet ice]

Or any JDK for that purpose

[dry yacht]

Yeah, it's probably a bad example. I need to look a bit deeper into it one day. There have to be a few lines of code which definitely decide this question which came up yesterday.

[wet breach]

but a lot of stuff under the sun package though is proprietary

[quiet ice]

Perhaps IBM J9 is propriatary, but it's since been open-sourced

[wet breach]

possible maybe, but its also possible for a JDK implementation to just implement something anyways. I just know openJDK is from oracle just open source version

[rotund ravine]

?jdk

[quiet ice]

The stock JVM is licened under the GPL, so the only thing that can be propriatry is outside it

So the java mission control center (or whatever it is called) is proprietary for example

And thus not present in OpenJDK

[wet breach]

nvm

JDK is free again

ever since 17

seems oracle didn't have any luck with that change they did some time ago lmao

[wet breach]

https://blogs.oracle.com/java/post/free-java-license

[quiet ice]

That was to be expected

[wet breach]

yes, but it took them a while to realize that

[fervent prawn]

What should the Main class look like in the plugins of version spigot 1.18 and higher?

[remote swallow]

public class PluginName extends JavaPlugin {
    @Override
    public void onEnable() { 
        // Startup code
    }
    @Override
    public void onDisable() {
        // Disable Code
    }
}

[fervent prawn]

I have to import something for "extends JavaPlugin" to work.

[remote swallow]

if you mean intellij saying that its onEnable and onDisable

[fervent prawn]

Error: "Cannot resolve symbol 'JavaPlugin'"

[rotund ravine]

?google Decimal formatter

[undone axle]

Google your question before asking it:
https://www.google.com/

[remote swallow]

do you have spigot-api in your maven/gradle?

[rotund ravine]

Import it, in IJ alt + enter whilst having your cursor in it

[remote swallow]

?main

[undone axle]

https://www.spigotmc.org/threads/why-you-shouldnt-name-your-main-plugin-class-main.493289/

[remote swallow]

do you have spigot/spigot-api in your build file

what version?

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[remote swallow]

also use maven or gradle

its a lot easier

[fervent prawn]

Okay, thanks!

[quaint mantle]

How would i make my scoreboard dynamic with my custom enconomies essence and tokens? Would I use a runnnable or hashmap or something? hmm

[storm scaffold]

import org.bukkit.entity.Zombie;

import static org.bukkit.Bukkit.getLogger;

public class Herobrine extends Zombie {
    public void spawn() {
        getLogger().info("Herobrine has spawned");
    }
}```

What am I doing wrong here? Shouldn't the isBaby() method (and all other methods this says are abstract) already be defined in the Zombie class?

[worldly ingot]

No. Your code won't even compile

You're extending a Bukkit interface, which isn't valid

[storm scaffold]

Why? Is there a way to make a class that is an extension of an entity?

I basically want to make it so I spawn the zombie, and can run my own methods on it as well as usual zombie ones

[chrome beacon]

You can't extend an interface

You implement it

You should be extending the vanilla zombie to get the behavior you want

[storm scaffold]

Oh ok, how do I do that?

[north cipher]

why do we haveorg.bukkit.util.Consumer if java.util.function.Consumer exists

[chrome beacon]

Bukkit is old

[slender kiln]

does anyone know a tab completer plugin for 1.8?

[chrome beacon]

Older than the java consumer

[chrome beacon]

Use #help-server

[north cipher]

alright il just use the java one, thanks

[storm scaffold]

How do I extend the vanilla zombie?

[chrome beacon]

Just like you extend any class Java

[river oracle]

For zombie specifically it's much more complex. You need to do byte code hacks real time and then type 'super duper crazy byte code extends Zombie'

[remote swallow]

packets probably

just use protocol lib

it'll bef ien

[river oracle]

Legit how I feel every time I hear scoreboard or teams

[remote swallow]

i simply dont deal with scoreboard or teams

my life is great

i also havent dealt with nms or packets yet

[river oracle]

I rather deal with packets than scoreboards

[eternal oxide]

nms and packets are fun to play with. I'd hate to make a plugin that depends on them though

[remote swallow]

if you dont do paid work you cant be forced to do stuff with them

problem solved

[storm scaffold]

What is the name of the vanilla zombie class name though? I couldnt find it

[lapis swan]

does the bungee.yml has the same syntax as the plugin.yml ?

[remote swallow]

the nms import for zombie probably

[river oracle]

Just use screaming sandals

[lapis swan]

But i Could add them ? what about permissions ?

okay so its only for name, version and main ?

[chrome beacon]

Have you imported NMS yet?

[orchid gazelle]

Its EntityZombie I think

[undone spindle]

im trying to use worldedit and worldguard but for some reason worldedit does not want to work as dependency in code

it does work as dependency in the pom.xml

[tender shard]

do other WorldEdit classes work?

[undone spindle]

i don't know

let me try

i mean if it autocompletes i think so right?

[tender shard]

then you are simply using the wrong import

Vector is probably in another package

or it's called Vec3 or something, idk

[undone spindle]

or it was something in an older version

or a fabric version

im using the bukkit version

but that shouldnt be it

[remote swallow]

i think wordedit use vec3

[tender shard]

yep, the API changed big time between version 6 and 7

[undone spindle]

tbh i don't even know how i can see that

i can look trough all tabs

or try making a variable

[remote swallow]

type Vector3 then just see if you get an import option

[undone spindle]

lmao ur right

[remote swallow]

https://docs.enginehub.org/javadoc/com.sk89q.worldedit/worldedit-core/7.2.0/com/sk89q/worldedit/math/Vector3.html

[undone spindle]

that helps thx

[lapis swan]

BungeCord
Should I use:
ProxyServer.getInstance().getConfigurationAdapter().getServers()
or
ProxyServer.getInstance().getServers()

First option seems to be more accurate as it should show the join able server but has this method a bigger impact on the Server ?
Is it better to get all and check when sending a Player ?

Is there a better way to send a message to all player on a server than iterating over the proxy player list in the Server info ?

[twilit garden]

Help is there a way to make a function that automatically separate lines if I input a string?
I’m trying to make making lore for items easier

[remote swallow]

i havent used bungee api but you could probably get a server instance and run broadcastMessage

[chrome beacon]

You can use String#split to split the string in to an array, convert that to a list and use it as lore

[twilit garden]

Ah I see thx alot

[lapis swan]

Could find a broadcast message for a special server only for all player connected sadly

[final monolith]

Can someone explain me why that code gives me a infinite line instead of a line from point A to point B?

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

[chrome beacon]

Thread sleep 💀

[final monolith]

Whats your recommendation? Im open for tips.

[chrome beacon]

Use run task timer

[final monolith]

Thats why i used Threads before, i changed to the BukkitRunnable

[chrome beacon]

or create your own thread

[quiet ice]

?jd-s It's async-safe?

[undone axle]

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

[quiet ice]

Doesn't say so, but I'll assume so

[spring pike]

hey man, I go remotivated to try to fix my issue. I hope you remember. I activated NMS for my project, how can I have a look at the hit logic? I only know java enough to make minecraft plugins, not much more sadly

[dry yacht]

It's kind of funny how people start nitpicking on some completely irrelevant implementation decisions rather than helping with the logic problem at hand, xD.

I'd really like to help you, but I kind of have a hard time understanding what you're trying to do, and there are too many undefined functions in that excerpt. Any way you can provide the full picture?

[final monolith]

It's kind of funny how people start nitpicking on some completely irrelevant implementation decisions rather than helping with the logic problem at hand, xD.

Hahahah, thats true.

I create that simple example: https://paste.md-5.net/okobazubiq.cpp

Thats suppose to create a line from location to target, but its generates a weird infinite line 🤔

im not too good with vectors xD

[ocean hollow]

how can I read this? Should I need to "plugin.getConfig().getString("books.green[0]")"? Or how?)

[final monolith]

yaml.getConfigurationSection("books").getConfigurationSection("green")

something in that way

[ocean hollow]

thanks

[final monolith]

for (Map.Entry<String, Object> key : getConfig().getConfigurationSection("books").getConfigurationSection("green").getValues(true).entrySet()) {
    Bukkit.broadcastMessage(key.toString());
}

[dry yacht]

Of course I remember! Well, I don't really know what to tell you, other than that it does require quite a lot of foundational knowledge to jump around in a massive codebase like the minecraft-server and keep a mental model of it's flow of data. It's sad how I myself haven't yet set up a proper environment to navigate through it, because I procrastinate all the time.

I usually use build-tools to build a version, then navigate into it's CraftBukkit folder and use grep -rni '...' src, where ... is what I'm searching for. I searched for new EntityDamageByEntityEvent, to check who creates these events. Then, I saw that it's inside of the src/main/java/org/bukkit/craftbukkit/event/CraftEventFactory.java, where many events originate. After a bit more digging around, the EntityLiving has a method called damageEntity0(final DamageSource damagesource, float f), which craftbukkit patched to spawn a new event through the event factory when that living entity took damage. I guess this would be the main place to put some "probes into", where one would start tracing this weird behaviour your server produces.

But again, this will take a pretty long time. Have you checked if the event gets fired twice if you get damaged twice already? If it doesn't (like it didn't ever for me), I think that we at least have somewhat of a startingpoint by knowing that. But make sure, really check that.

[final monolith]

Do a debug.

[spring pike]

thanks a lot! I will experiment a bit on my own with this knowledge and hopefully come to a conclusion

[dry yacht]

Thanks, I'll take another look at it. I just often times get headaches when looking at other peoples' code and my mind kind of starts closing up, which is why I have a hard time with little excerpts like these, xD. In general, if you want to ask a question in here, try to isolate the logic beforehand into a simple little unit with as little side-effects as possible, so that others can get a hold of what you were thinking when you wrote it. Gonna get back to you in a sec!

[final monolith]

Thanks for the tips!!

[storm scaffold]

For making a custom entity, would it be better to make an extension of a vanilla entity, or to make an entirely new class where it has an entity attached to it in an instance variable?

[ivory sleet]

I like the second design

where you delegate

since inheritance is harder to work with as it strongly couples your logic with the already existing base logic

yk

composition over inheritance :3

[dry yacht]

I really cannot seem to find any issues with the logic you use in your code... You keep track of the distance travelled by covered, and as long as that's smaller than distance, you add space to it every time you add vector to p1, where vector is the directional unit-vector of length space.

Don't quite get what you're trying to do with the outer row loop, but that shouldn't affect anything...

[dry yacht]

Which is why I think the actual issue has to be with your input parrameters and the way you call that logic.

[dry yacht]

If you need any help, I'd need to be able to run your exact configuration locally, which in essence means that you'd have to zip up your server directory and send it over as is, xD. Seems like you got a funny build there, as I couldn't even start it last time I tried.

[spring pike]

funnily enough, I tried copying my paper.jar over to another folder to test the issue on a server without plugins at all, I couldn't even start it with the same start.bat

but if it works, it works i guess

[dry yacht]

Can't you just try loading something less "exotic" once and see, if the issue still persists? Like just some simple spigot release of 1.8.8 from any online mirror. I have no idea what all of these forks add/remove from NMS patches, which might cause any additional trouble I'm not even thinking of.

[lapis swan]

is there a difference between getProxy.foo and ProxyServer.getInstance.foo ?

[spring pike]

I tried even less exotic, I opened a lan server for my cracked 2nd account, still the same

[wet breach]

and there we go

[ivory sleet]

ye

[dry yacht]

So how do you test that? Just clicking fast when in combat and checking to see if you get double-damage? I don't know, maybe I'm just too stupid to reproduce it, xDD.

[ivory sleet]

like its the same instance

[spring pike]

I put my 2nd account into a hole and started crit-hitting him while clicking fast. Much like in the video i uploaded

[ivory sleet]

but one is through the singleton, and one through the Plugin base class you derive

[wet breach]

one is a static the other isn't

[lapis swan]

so which is the "better" to use

[wet breach]

Generally you should go with the normal method and only use the static way when you need it

[ivory sleet]

For unit testing, Plugin::getProxy

but idm really I suppose

[wet breach]

it doesn't matter ultimately, but for consistency though best to stick with the standards 🙂

[lapis swan]

so which is the standard ?

[wet breach]

As I said, only use static when you need it, like anonymous classes for instance

where to pass something to the class it would need to be static anyways

[ivory sleet]

there's no standard

but singletons are usually avoided in the modern world

since they cause more issues than they solve

(proven in the industry especially)

[wet breach]

well when used incorrectly certainly XD

[tardy delta]

my programming teacher uses singletons 💀

[ivory sleet]

ye

[lapis swan]

I'm not java enough to understand which is the singleton 😄

[remote swallow]

on pdc if i were to get an int, if that wasnt set would it return null or 0?

just checked jds, it says null

[lapis swan]

So in a command if i do not use the singleton i would use an instace of my plungin instead an than use the .getproxy ?

[eternal night]

pdc returns you an Integer. Make sure to store it as one and not an int else you'll run into auto unboxing NPEs if the value is not set

[remote swallow]

ah, so it would just be 0 if not set?

[dry yacht]

If we're talking about NPEs due to auto unboxing, I'd say you get null if not set, otherwise there would be no reason to differentiate between boxed/unboxed.

[remote swallow]

ah mk

[kind hatch]

That’s the point. If you didn’t know, primitives cannot be null, so they will always return something. The wrapper objects have that third state so by default, they are null.

[dry yacht]

You're accessing books.green, where it seems like books is an actual section, but green is not and returned null, which is why you cannot call getValues(true) on it.

[ocean hollow]

Just remove true?

[remote swallow]

you dont really need the getValues part

also use camelCase for var names

[ocean hollow]

okey

[dry yacht]

You don't have the section green in the section books, so you cannot access it. Try having a look at your actual YAML file first, and check if you really write to that section before trying to read from it.

[dry yacht]

green is not a configuration section, but a list of objects

[fallow violet]

you can sign 2 objects to a list?

is it a hashmap?

[dry yacht]

This is just an unusual format of notating a list. It's JSON equivalent is basically:

green: [{name: ..., cmd: ...}, {name: ..., cmd: ...}, ...]

Usually, you would have a newline right after the - and start at the indent of cmd.

[wet breach]

yaml is a superset of json

[dry yacht]

So...?

[wet breach]

you can use json in yaml

if that is what you prefer

[dry yacht]

Yes, this is a known fact. I was not at all talking about preference tho, I was just trying to provide a more familiar notation to @fallow violet, because they thought that green's value was a map, mapping objects to objects, which is also possible in YAML. It's a list tho, which is formatted in a very unreadable way - but still a list.

[lapis swan]

do I need to run the ServerInfo.ping() function in a Scheduler for example runAsync or could I just use it directly ?

[wet breach]

I am surprised their yaml isn't giving them errors on that indentation

for their list objects

since it should be indented 2 in

[dry yacht]

I debugged the noDamageTicks variables of all players on the server (just my two accounts), and it seems like the player can still take damage, even if that variable is greater than zero. To be honest, at this point I'm just confused as hell and think that this may be a massive rabbit-hole, xD.

[dry yacht]

That's valid notation, as there's no ambiguity and the spec allows for multiple ways to notate the exact same thing. One of the many reasons why YAML is a headache.

[lapis swan]

                        proxy.getScheduler().runAsync(JoinMeBungee.instance, new Runnable(){
                            @Override
                            public void run(){
                                si.ping(new Callback<ServerPing>() {

                                    @Override
                                    public void done(ServerPing result, Throwable error) {
                                        //my code
                                        
                                    }
                                });
                            }
                        });

I wrote this but it feels a bit strange

I don't understand it but I like it 😄

Lambda stuff I guess ?

[quaint mantle]

so I know in client side mods there's the Minecraft class, is there any way to do like EntityPlayer.getMinecraft() just like in forge? but on server side

[dry yacht]

Every interface which has just a single method can be replaced by an equivalent lambda. This saves time by you not having to create a new anonymous class instance with new.

[tender shard]

follow the instructions on compiling your own spigot build

[austere cove]

what about this 👀

@FunctionalInterface
public interface MyInterface {
    void myMethod();
    default void myOtherMethod() {
        // Code
    }
}

[tardy delta]

a single abstract method :}

smh is that java formatting, those colors and fonts are weird

linux moment

[austere cove]

doesnt that match github colors?

[tardy delta]

ye

[austere cove]

looks better than this tho

[tardy delta]

nahh

that one looks fancier

[river oracle]

I'm on linux this is what mine looks like

[tardy delta]

linux fonts are weird

and idk what normal ones are

[river oracle]

debian prob has weird defaults

[tardy delta]

i still dont have nvidia drivers lol

[austere cove]

vomit colors

[dry yacht]

Yeah, what about this? xD

[austere cove]

still works as a lamba but has >1 methods

[tardy delta]

Conceptually, a functional interface has exactly one abstract method. Since default methods have an implementation, they are not abstract. If an interface declares an abstract method overriding one of the public methods of java.lang.Object, that also does not count toward the interface's abstract method count since any implementation of the interface will have an implementation from java.lang.Object or elsewhere.

[remote swallow]

is that real discord?

[quaint mantle]

does that include all the files by mojang? like not just the ones supplied by buildtools, but every .class file in existence. also please ping me on reply

[river oracle]

yes

[remote swallow]

i dont believe you

[river oracle]

its just custom css

[remote swallow]

you would still need something to parse that

[river oracle]

thats not how css works but!

don't need a css parser its read by the application

[remote swallow]

open asar be like

[river oracle]

all you have to do is edit the current values within that app you don't have to inject new values

[dry yacht]

Because you have a default implementation on the other method. I know, my definition wasn't exact, but I dislike the default keyword which is why I made myself forget it's existence, lol

[somber berry]

I am trying to protect the blocks from a list from being destroyed by explosions but it seems it does not work.

what am I doing wrong? 🙂

[quiet ice]

To be fair, there can never be an object with a single method

[spice shoal]

Hi guys , i have a problem.
When I restart the server , spawn resets ...
How do I get it to save in config?

[rough drift]

new discord experiment is adding custom themes

[rough drift]

config.save()

[spice shoal]

o i have missed it , thanks

[dry yacht]

That's why I talked about an interface specifically in my first answer on this, as the Object base class of course brings it's whole API with it. These interfaces act like a function type, as often times indicated by the FunctionalInterface annotation. Kind of like a function pointer in C. Lambda functions are just syntax sugar, as they are in cpp (I'd assume).

[quiet ice]

All interfaces are objects

[tender shard]

obviously, what else would they be lol

interfaces are classes and classes are objects, yeah

[dry yacht]

In internal representation, but... what? How? I'm confused about that tbh

[tender shard]

Class<Player> playerClazz = Player.class;

interfaces, in bytecode, are just classes that have the "interface" flag set

[dry yacht]

.class is internal representation in my mind. But the interface itself is just a contract, and when used with a lambda, it only defines a single method. I think that we're basically talking about different levels of abstraction.

[tender shard]

at least I think so. geol knows more about bytecode than I do, so maybe he can confirm it, or complain if I am mistaken

[tender shard]

every class is an object in java

otherwise reflection wuoldn't work

[dry yacht]

Yeah, of course, everything's an object in JS too, but I would never think about that when explaining to somebody how lambdas work with interfaces. This is an implementation detail which is not of interest when ig comes to this limited view I was getting at.

[tender shard]

well not everyhting is an object in java

for example primitives

that's why you cannot return "null" from an "int" method e.g. lol

[dry yacht]

Yeah, sure, didn't mean to suggest that. Just drew an anology.

[tender shard]

fair enough

SQL be like

SELECT name FROM dictators LIMIT 1;

result:
Hitler

[round crag]

Hey sorry I don't know if I can ask this question here but you know a BungeeCord 1.19.3 npc plugin ? Please

[tender shard]

#help-server

[round crag]

Ok thx

[dry yacht]

Maybe my views on things just need a little update. I always imagined interfaces as this inert type which have no functionality, where .class is kind of "auto-generated" code and just tells implementers what their function tables have to at least contain. Well.

[naive bolt]

what does this mean in my plugin

[sullen marlin]

Sir this is spigot

[naive bolt]

i mean its a plugin issue not paper i would think

[orchid gazelle]

Yes it is

Can you show us your code?

[eternal oxide]

recreate the issue on Spigot

[naive bolt]

idk how it originated in the first place

[quiet ice]

Thread.sleep?

[naive bolt]

non of that

[quiet ice]

Or while (true)?

[orchid gazelle]

We need the code probably

[jagged monolith]

Either way, see if you can reproduce the issue in spigot. Otherwise, paper isn't really supported here.

[orchid gazelle]

Does not sound like a paper issue

[naive bolt]

its on a paper server but not using paper api

[quiet ice]

Or actually, MinecraftServer#stop is getting invoked

[eternal oxide]

doesn't matter

[quiet ice]

So did you shut down the server?

[orchid gazelle]

The code

We need the code

[eternal oxide]

If you can produce the error on Spigot we can help

?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.

[naive bolt]

ill see what paper support say

[quiet ice]

Show us the whole stacktrace and then I can help (even if the other fools cannot)

[orchid gazelle]

Imma try to help you on paper lmao

[quiet ice]

Don't - you'll be laughed at if it is what I think it is

[naive bolt]

let me dive back into the logs i just snapped that real quick while it was there

[orchid gazelle]

We need the C - o - d - e

[naive bolt]

I cannot give you that

[quiet ice]

Nah, stacktrace is enough here

The "Supressed:" thing is already a good enough clue of the cause

[orchid gazelle]

Then we probably cannot help

[dry yacht]

What do you think it is? Just curious.

[quiet ice]

Invoking a command while stopping the server

[orchid gazelle]

Good idea

[dry yacht]

Oh

[quiet ice]

Or likely invoking /stop itself

[tardy delta]

why am i even in the paper server

[dry yacht]

Well, I would have been way off then.

[orchid gazelle]

Why not?

[tardy delta]

why would i

[orchid gazelle]

Because they are helpful if you have a problem

[quiet ice]

You also see above that the server is experiencing significant problems with watchdog

[tardy delta]

im not using their api either

[quiet ice]

So it is also possible that watchdog killed the server

[naive bolt]

https://mclo.gs/AyoFg6g

alright that seems to be all of it

[tardy delta]

im only using their fast reload command

[quiet ice]

Yep watchdog

[dry yacht]

Oh, that was what I thought about. That they block too long somehow, and the main tick loop obviously doesn't allow that, which is why a watchdog triggered

[sullen marlin]

Again, this is spigot

Last warning

[naive bolt]

I was told to post that

[dry yacht]

Got flashbacks of the watchdog in freertos of the ESP32, haha

[jagged monolith]

You are running a paper server so ask in the paper discord.

[naive bolt]

I said i would go paper but was told no

[orchid gazelle]

Reproduce the error on a spigot server or ask on paper

So people here won't cry about it ;)

[quiet ice]

[23:17:21] [Paper Watchdog Thread/ERROR]:         AndyisBlocks-1.0.jar//me.justacat.andyisblocks.structure.Structure.<init>(Structure.java:38)

These two lines of code deadlock

[naive bolt]

i was told to be here. not of choice

[eternal oxide]

So you won't be kicked/banned

[naive bolt]

I did go to paper

[dry yacht]

Is it that hard to substitute paper.jar for spigot.jar and retry? You're likely gonna get the same issue...

[tender shard]

AndyisBLocks fucked up in Structure line 38

[orchid gazelle]

Thats the same thing

[quiet ice]

Try running it with -Xmx1G -Xms1G - don't run it with more ram

[tardy delta]

i once crashed the jvm with worldedit 💀

all threads decided to throw an out of memory after a while

[orchid gazelle]

99.8%, yeah

[quiet ice]

If it crashes the fault is in onCommand, otherwise it is in your constructor

[naive bolt]

I will not post here anymore of this issue as md is mad

[quiet ice]

This channel is full of idiots anyways

Stacktraces? What are those? Never heard of em?

[tender shard]

?

[dry yacht]

Think you should have gotten enough ideas by @geol on what's the issue anyways, you should be able to track it down now using common programming logic.

[tender shard]

got banned there? me too

[eternal oxide]

Its not a case of being mad. It's a case of This is support for Spigot not forks. Your issue may have many underlying issues/causes and we won't waste time chasing bugs introduced in forks. Replicate the issue on Spigot and we'll be happy to help

[orchid gazelle]

For what?

[tender shard]

we dont talk about that here

hmu in DMs if you wanna know

[orchid gazelle]

Did not see your messages there, hmm. Bro, just replace paper.jar with spigot.jar and come again

[tender shard]

the issue clearly is their "Structure" clas in line 82

[remote swallow]

whats the player equivalent on bungee

[tender shard]

has nothing to do with paper vs spigot

[quiet ice]

Don't try to understand

You can't bring senses to the senseless

[naive bolt]

Look i don't want to talk more abt the issue here as i will get banned. and I kinda need this server

[remote swallow]

found it, proxied player

[tender shard]

the only way to get banned here is to post homophobic or racist messages

[dry yacht]

It's literally a pure logic issue, yet people love to be butthurt about the detail that the stacktrace contains the forbidden word paper.

That's why minecraft server modding is at the stage and place it's at, lol.

[orchid gazelle]

Yes but he is gonna get yelled at when coming here with "paper-issues", so this is just for the future

[remote swallow]

or advertising

[eternal oxide]

or ignore warnings from md5

[orchid gazelle]

Thats what I mean

[tender shard]

yeah that's true too

[naive bolt]

What have i caused

[remote swallow]

a certain canadian doesnt like advertisers

[sullen marlin]

Funny how you all seem to have no problem refusing to help offline mode servers

[tender shard]

nothing, this channel is always just a weird off topic spam

[naive bolt]

Bungee server

actually...

[quiet ice]

There aren't that many out there

[sullen marlin]

The rule is if you want support from this server, you use Spigot

[tender shard]

erm all big servers are offline mode bc of bungee

[eternal oxide]

I help with offline, if they have a reason to be offline other than piracy

[sullen marlin]

You have been warned, that should be the end of it

[jagged monolith]

I always refuse help straight up for them. Unless bungee is used. Unless bungee is offline too :p not just because of piracy but all the issues it brings for uuids etc..

[dry yacht]

Uhm... that's not how offline mode should be defined, xDD.

[naive bolt]

Mate. Do i look like im the one wanting to continue this

[tender shard]

did I misundertand sth? all backend servers are always offline mode and have "bungeecord: true" in their spigot.yml

[sullen marlin]

You (plural)

[orchid gazelle]

Thats right

[tender shard]

I am not sure what md5 is talking about, did I say sth wrong or anything?

[jagged monolith]

Yes, but some people run bungee in offline as well.

[remote swallow]

i think its the stuff about no paper help and that

[tender shard]

ah ok

[dry yacht]

What matters is that the player connection has to be authenticated against mojangs API. If the proxy already does that, why would the subserver have to be in onlinemode then. You cannot pass without having payed for an account.

[tender shard]

yeah sure, bungee handles that

[remote swallow]

am i correct in saying ProxiedPlayer player = ProxyServer.getInstance().getPlayer(vote.getUsername()); would get me a player if they are online on any of the servers registered on bungee

[orchid gazelle]

Dear md5, why is there a problem with it when its clearly a plugin logic issue, not paper issue?

[naive bolt]

We use the correct security measures to lock the backend servers to only allow traffic through the proxy

[tender shard]

@naive bolt show "Structure" line 38 pls

[naive bolt]

||blocks.put(new Vector(x, y, z), block.getBlockData());||

[sullen marlin]

Because this is the spigotmc community

[eternal oxide]

I already told you why. This is Spigot support. We help anyone USING spigot not a fork

[quiet ice]

It is mostly a surrounding line

[orchid gazelle]

So im not welcomed when I use paper which basicly uses this software?

[tender shard]

huh weird. maybe you indeed have to ask on your fork's discord instead, because that code should not kill the server

[sullen marlin]

💪🔨

[remote swallow]

paper is a fork that changes a lot of stuff internal

[eternal oxide]

correct

[sullen marlin]

Correct

[orchid gazelle]

Bruh

[tender shard]

what did you expect

[jagged monolith]

I'm safe then xD I don't even own a server an my plugins are all in spigot api currently xD

[tender shard]

if person A forks my stuff, and calls it B, then person C comes and has an issue with A's work, why would I have to answer?

I also use paper, but whenever I encounter an issue, I always see whether spigot has this problem too - if yes, I mock people here, otherwise I don't

[remote swallow]

what could i call a method that gets, something in a database then raises that by one and saves it back to the db

[naive bolt]

imma go to paper and they will start crying that im using 1.19.2 and not .3 like they always do

[orchid gazelle]

I expect people to help with literal spigot issues without crying that the word "paper" appears in a log. But lets just leave that, or else im gonna get banned probably

[tender shard]

.getAndIncrement(...)

[remote swallow]

thats smart

[orchid gazelle]

Please leave that now

[remote swallow]

do you want a gregg

[tender shard]

paper causes many issues though. it's normal that we ask you to use spigot if you come here

[sullen marlin]

Mmm grilled egg

[tender shard]

md simping for greggs again lol

[orchid gazelle]

Never seen that xD

[remote swallow]

what about nuggets

[tender shard]

anyway, paper often has serious buggs. e.g. in paper 323 you couldn't use Player#chat(String) without it throwing exceptions, while it worked on spigot the whole time

so yeah, we cannot help people who use paper

[remote swallow]

?whereami be like

[undone axle]

https://cdn.discordapp.com/attachments/864180468680360027/944415049462714469/whereami.mp4

[sullen marlin]

Continue this conversation at your own peril

[orchid gazelle]

Sure it does, but sometimes it is just normal plugin issues

[sullen marlin]

The position is clear

[remote swallow]

[tender shard]

sry. I just wanted to explain the reasons of why ?whereami is a thing

[jagged monolith]

The issue, is that if they are using paper, paper has changed the spigot code, so it's harder to debugg the issues. As It may be paper related. We don't think what they change exactly in the spigot code. So what may work fine on spigot, is completely different in paper.

[orchid gazelle]

In other words: the next thing about that topic gets a 🔨

[tardy delta]

a hammer

[remote swallow]

a more like

[tender shard]

yes, sometimes. but not always. and that's why people are expected to use spiot when they ask for help on spigot's discord

I mean, you also wouldn't email the debian mail list when you have issues with ubuntu, right?

[orchid gazelle]

So next time im asking for help here, I should run the same thing on a spigot server first and then come here?

[remote swallow]

alex you probably want to stop before md smacs you

[tender shard]

exactly

[orchid gazelle]

Thats an issue because some things need another software to work

[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.

[jagged monolith]

I must be still tired. I swear you said "want to shop"

[remote swallow]

thats happened to me while wide awake

[tender shard]

then use the "another software"'s discord

[orchid gazelle]

Damn I'd love to continue this discussion but 🔨

[remote swallow]

whats the sql thing to insert or update

does that even exist

[kind hatch]

I’m confused. Most plugins work just fine on spigot due to the whole compatibility thing paper has with spigot. So testing plugins on both jars should work in most cases.

[eternal oxide]

depends on yoru backend

[tender shard]

executeUpdate(...) ?

[orchid gazelle]

(Which, in a lot of cases, might not help you if its a small fork)

[naive bolt]

i got a real question what processing charges do you get on the donations for their to be a $10 minimum?

[remote swallow]

actually in the statement

[remote swallow]

as in? like what type of sql?

[eternal oxide]

yes

[remote swallow]

mysql

[tender shard]

yeah but that's not our fault. I mean, if you use spigot, you can ask here. If you use something else, you have to ask somewhere else

[orchid gazelle]

If I have a function that uses the paper-api and also needs a paper patched function, it wont work with spigot

[remote swallow]

paper lib

[eternal oxide]

REPLACE INTO

[remote swallow]

thanks

[dry yacht]

I think the main issue is that they very likely have another watchdog implementation at paper.

But again, this was not specific to that, but a general logic issue. Every server would've died, just maybe in another way. Which doesn't affect the solution.

[orchid gazelle]

So basicly if I fork spigot and change 1 line of code, im not welcomed here

[naive bolt]

🤣

[sullen marlin]

How is this still a point of contention

[naive bolt]

add a comment to the code

[sullen marlin]

If you want support from the Spigot community use Spigot

End of story

[tardy delta]

people are a little slow of understanding

[sullen marlin]

No if's, no buts, clear as crystal

[tender shard]

nobody ever said that. But you cannot expect to use <random fork X> and then expect spigot people to help you

[sullen marlin]

/thread

[tender shard]

?thread

hm

[dry yacht]

Maybe because some people are passionate and would have really loved to solve that deadlock/timeout issue and are now hurt because it got stomped into the ground.

[orchid gazelle]

In my opinion, thats an unlogical thing but aight

[tender shard]

nobody said that

[orchid gazelle]

Oh yes they did

[tender shard]

no

[orchid gazelle]

?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.

[eternal oxide]

It wasn't stomped. Show it happens on Spigot and we'll help

[quaint mantle]

I found a file located at C:\Users\USERNAME\.m2\repository\org\spigotmc\minecraft-server\1.8.8-SNAPSHOT\minecraft-server-1.8.8-SNAPSHOT.jar, is this the deobfuscated server jar? I noticed that it has more files than the BuildTools output, including the com.mojang libraries, for example

[tender shard]

nobody said that you're not welcome here anymore

[sullen marlin]

Yes

[tender shard]

no. everything below 1.17 will always be obfuscated

[tender shard]

whut?

deobfuscated?

in 1.8?

[sullen marlin]

Well spigot deobfuscated

[orchid gazelle]

This is not an actual thing, just an imagination what happens if I fork and change 1 thing

[jagged monolith]

It's basically what plugins hook into if they use the spigot api

[tender shard]

yeah okay so let's call it "half-way deobfuscated"

[dry yacht]

Kinda was, don't think the person originally asking this is still in the mood anymore. As am I. I'm out at this point, this conversation is not going anywhere anyways.

[mighty aurora]

Does anyone here know any reasons to use something like packetevents over protocolLib?(I just want to know like what benefits and cons their are to both. Not asking for opinions that X is better than Y just wanting to see what they can do so I can decide what to use).

[naive bolt]

called it

[quaint mantle]

so is there a way to recompile the decompiled source code? i loaded that up in maven

[kind hatch]

I fail to see how that is illogical. Just because two things have similarities does not mean they are the same. Spigot has its own set of changes, paper has their set of changes. The only line of similarity is that paper forked off of spigot. Meaning that they changed things. Just because they stated compatibility does not mean they didn’t change things under the hood.

[jagged monolith]

ProtocoilLib is messy and annoying. The api should be used in favour of messing with packets

[sullen marlin]

It will be full of errors that's why only the needed files are added

[orchid gazelle]

Lmao

[sullen marlin]

Next person to say a word on the topic gets 🔨

[quaint mantle]

so is there any way to modify the code of the minecraft server.jar? even spigot server.jar but with full access to every .java file

[mighty aurora]

So your saying I should work directly with packets using spigots API ? or what API are you referencing.

[jagged monolith]

Why would you need to?

[sullen marlin]

MCP/Forge. You're not going to need every file though so just add what you need and fix the errors as you go

[eternal oxide]

Yes follow the ?contribute link to see how to build your own jar

[tender shard]

then it's no problem ofc. You just have to understand the following: forks like paper change like thousands of lines of code. If now you encounter a bug, this might or might not be caused by those changes. You are supposed to check whether this bug is also present in the "original" spigot .jar. If it is, feel free to report it. If it's not, report it to the fork's devs you are using.

I e.g. have encountered a ton of bugs that were only present in paper, but not in spigot. And I always reported them to Spigot, because I thought "if it's in paper, it's in spigot too", although that's not true. So I accidentally made many people spend their free time to check out something that wasn't their fault. And that's not good

[jagged monolith]

Is there a particular reason you want packets. Because the api can do a lot that the packets can.

[orchid gazelle]

With that logic: If I have a jacket and add a jacket pocket to that, thats a whole different jacket

[mighty aurora]

I was told the only way I could make a player completely invisible(including armor) while still having them be damageable was to mess with packets.

[kind hatch]

Make a thread. I ain’t trying to get banned.

[naive bolt]

Continued Discussion

[quaint mantle]

well i was hoping to just play around with every library, the com.mojang.authlib stuff intrigued me as i'm thinking about making my own game so i would like to see how mojang did it and do something similar and wanted to play around with that, is it possible to modify those files?

[sullen marlin]

Packets aren't going to allow them to be damaged because the other players client won't hit them

[mighty aurora]

When I'm merely making it appear that they don't have armor using it?

[sullen marlin]

I suppose you could raytrace server side, but that still doesn't need packets

[remote swallow]

am i correct in saying statement.setInt(1, newInt) and statement.setString(2, uuid.toString) on "REPLACE INTO `simp_votes` (`votes`) VALUES (?) WHERE `uuid` = ?;"

[mighty aurora]

I am using packets only to hide the armor. I use regular invis to make the body invis

[sullen marlin]

If the body is invis the armor won't show

[naive bolt]

nice the thread was deleted

[tardy delta]

it starts at 1 yes

[mighty aurora]

Not anytime I've tested it even in latest version

[eternal oxide]

yes

[mighty aurora]

or at least not while using invisiblity potion

[dusk flicker]

stopping the discussion vs moving it to a thread arent the same thing

[remote swallow]

thankos

[sullen marlin]

Oh you mean potion not full invisible

[mighty aurora]

How else would I make them invisible?

[sullen marlin]

hidePlayer

[jagged monolith]

It would be nice if you could hide armour. Like a getarmor.hide so you can wear amour but have it hide if you only want to show player skins an not cover it. Or only show specific parts or amour

[mighty aurora]

That would prevent the player from taking damage

which is a problem for me.

[kind hatch]

What about hideEntity?

[sullen marlin]

What about sendEquipmentUpdate to remove the armor

[tardy delta]

hideEntity doesnt hide them from tab iirc

[mighty aurora]

Is that API?

[kind hatch]

That’s a thing?

[sullen marlin]

That's the API replacement for those packets

[kind hatch]

Tf. Guess I never noticed it.

[jagged monolith]

Check the docs more often :p

[naive bolt]

md how come donation limit is minimum $10

[sullen marlin]

Because there's overhead and also if you can't spare $10 you probably need the money more

[naive bolt]

paypal overhead isnt that bad is it

[jagged monolith]

Donating does have its benefits. I've done it. Years ago though haha

[sullen marlin]

Overhead isn't just paypal

It's administration, risk

[naive bolt]

i ended up donating to mcm just to change my username

[sullen marlin]

Good for you?

[mighty aurora]

md_5 does sendEquipmentChange persist across server restarts and/or player disconnect/reconnect?

[sullen marlin]

No, it's basically just packets

[kind hatch]

Hey md. Is there a way to better link the javadocs to the discord commands? Smth like ?jd-s Player#updateInventory() and it return an embed with the description of the method? Also a direct link to the page.

[sullen marlin]

You could make one

[remote swallow]

is there a mysql thing to check if a string is already set?

or would i have to query all and check each

you can use =

like have different purpose

[tardy delta]

like without % and i forget the other is like useless iirc

[remote swallow]

so SELECT * FROM table WHERE column = MySTring;?

[sullen marlin]

Eval? Gradle? Scary. Looks helpful though

[remote swallow]

gradle is love

gradle isnt scary

you could also convert it to maven

[smoky oak]

eh i only use maven cuz im too lazy to learn gradle

[naive bolt]

gradle>maven

what is their to learn about gradle. simple stuffs

[sullen marlin]

I mean it has like a gradle command and stuff

[remote swallow]

the best advice ill give you md is dont use kotlin

[smoky oak]

what i meant is that i can copy paste the pom and i only need to change name and version, ie, a working system

which

i wont change since it works

[jagged monolith]

What about the bot DocDex, that does it already.

[sullen marlin]

Yeah that's the mongo one

[jagged monolith]

I know a couple other discords use it, doesn't look bad. very useful haha

[sullen marlin]

Or MySQL apparently

Looks to have developed since I first saw it

[naive bolt]

maybe should just write a github wiki on the whole api 🧑‍🍳 👌

[jagged monolith]

Maybe more reason to invite it here?

[sullen marlin]

delete: Deletes collections from mongo then stops the app. This is used by the updater subproject, once again, you won't need to use this command.

Docs still reference mongo

[remote swallow]

anyone that mysql's would "SELECT * FROM my_table WHERE categories LIKE ?"; check if it contains value that i would set ? to

[remote swallow]

or do i use this

[hazy parrot]

here is example of jda butler, looks really cool imo

[tardy delta]

isnt like used like %something else%

[remote swallow]

no clue

[tardy delta]

like a kind of regex

[hazy parrot]

yap

[tardy delta]

i used to learn that stuff in highschool

[remote swallow]

i just need to check if my collumn contains a string already

[tardy delta]

i think theres also _

[remote swallow]

i dont mysql

[mighty aurora]

Does anyone know how to get all online players? I'm trying to use getOnlinePlayers() but can't seem to figure out how to call it.

[hazy parrot]

if you want exact string use = if you want "regex" like use like

[remote swallow]

Bukkit.getONlinePLayers

[remote swallow]

ah kk, thanks

[jagged monolith]

LIKe basically means similar to

[remote swallow]

can i use = ? to specify the string elsewhere

[jagged monolith]

So it would match anything similar to what you add it

[tardy delta]

theres also WHERE categories regex "some regex"

[remote swallow]

how would i specify this ```
"SLECT * FROM simp_votes WHERE uuid = ?;"

[tardy delta]

that would select all records where the uuid is the exact same as the param

[remote swallow]

ah

perfect

[jagged monolith]

If you spell select correctly 😉

[remote swallow]

yeah just noticed that lol

that would be executeQuery right?

[tardy delta]

ye

[remote swallow]

also how would i get if it matches

im guessing resultset something

[tardy delta]

execute would work too but it doesnt returns a resultset iirc

[tender shard]

test

yay my timeout has ended

[tardy delta]

ResultSet rs = statement.exexQuery()

[remote swallow]

yeah ive got that

[tardy delta]

if (rs.next()) // found a record

[tender shard]

execQuery() is for UPDATE and INSERT etc

wait no

it's execStatement(), isnt it?

tbh no clue

[remote swallow]

exec update for update/insert

exec query for select im guessing

[remote swallow]

so if thats passes it already exists?

[tardy delta]

it acts like a cursor that stands before the first record found

next() moves it down and returns if theres something there

if theres a next you can call rs::getString and that stuff

[remote swallow]

so if it doesnt exist it (rs.next) would return false

[tardy delta]

yes

[remote swallow]

ternary operator party

[tardy delta]

i can just tell you to read the docs

[remote swallow]

no clue which i would read tbh

[mighty aurora]

How do I use sendEquipmentChange to make the armor appear as air? More specifically what value do I use for the 3rd parameter?

[remote swallow]

you send the entity, so player, the slot eg chestplate, andt he itemstack you want to display

so air

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#sendEquipmentChange(org.bukkit.entity.LivingEntity,org.bukkit.inventory.EquipmentSlot,org.bukkit.inventory.ItemStack)

[mighty aurora]

According to that you can only use obtainable items which air is not

[remote swallow]

do it anyway

[kind hatch]

So new ItemStack(Material.AIR) doesn’t work?

[mighty aurora]

It was complaining that a method call was required

[tardy delta]

ItemStack.AIR when

[remote swallow]

never probably

[tardy delta]

still doesnt say what kind of air 🥺 cave air

[tender shard]

.isAir()

[mighty aurora]

nvm I tried it again and it works just fine...

[remote swallow]

does bungee have a join event?

found it

[tardy delta]

fuck its already 1 am

[remote swallow]

its not midnight yet

stop lying

[tardy delta]

you better stop lying

[glossy wren]

quiiiick question I'm a newer developer, why is player health represented as a double? Can't it only be a whole number?

[smoky oak]

u can take more precise amounts of damage than half hearts

[jagged monolith]

Half hearts etc..

[smoky oak]

most things just dont do finer than half hearts

example

protection enchantments usually result in non-half-heart numbers

since they're percentages

[glossy wren]

got it

[smoky oak]

not flat decreasess

[glossy wren]

kinda stupid imo, but ty

[remote swallow]

anyone know of decent bungeecord tab complete examples?

[smoky oak]

eh just keep in mind 1 heart = 2 hp

[mighty aurora]

Anyone know how to reset whats done by sendEquipmentChange?

[smoky oak]

(guessing here) call an inventory reset, iirc theres a method for that

[mighty aurora]

sendEquipmentChange fakes a players gear changing

[worldly ingot]

You'd have to just call that method again with whatever is in that player's slot

player.sendEquipmentChange(EquipmentSlot.CHEST, player.getInventory().getItem(EquipmentSlot.CHEST));

or whatever the method sig is. Close to that

Because remember, the server still has the real item

[mighty aurora]

Yeah I'm trying that. I had thought it would either be more complicated or their would be a different way of doing it.

Is their a way for me to create an iron golem that acts like a wolf would?(As in protects the player from things that attack it and attacks what the players attack?)

And if so how?

[smoky oak]

uh

probably just copy the wolf ai onto the iron golem ai

[mighty aurora]

uhhh

[smoky oak]

if u do that u need nms tho i believe

[zealous scroll]

you can just check for nearby blocks at a given radius and delete them if they're lava

it looks like it's 6

the diameter would be 12 i suppose

i went in game

the air blocks inside the clay seem to be the shape of the blocks the sponge takes

it also behaves very inconsistently for some reason

[last sleet]

I can't find the interface Enemy, even though the docs say it exists. I'm trying to find a way to know if a mob is hostile (aka a monster) but some mobs don't extend Monster, like Phantom, even though they should...

[worldly ingot]

It was added in like the last commit or two

It's very very recent. 1.19.3 only

If you're on .3, update your server

[last sleet]

oh darn

well I don't wanna update for now, is there another way or do I have to manually check ?

[worldly ingot]

I mean Enemy consists of Monster + a few other interfaces, so you could instanceof check them all if you'd like

public static boolean isEnemy(Entity entity) {
    return entity instanceof Monster || entity instanceof EnderDragon
        || entity instanceof Ghast || entity instanceof Hoglin
        || entity instanceof Phantom || entity instanceof Shulker
        || entity instanceof Slime;
}```

A little ugly, but that's in essence all that Enemy covers

[last sleet]

alright

thanks ;)

[worldly ingot]

It's very very recent. 1.19.3 only

well I don't wanna update for now, is there another way

[mighty aurora]

If I have created a custom ability and want a way of deactivating it prior to it finishing if an event happens what would the best method of marking the player as having the ability active(To then check for active players). The ability basically is just potion effects and currently I check for them having the permission to run it and the potion effects. I realized that this is a bad method of checking as it can activate at the wrong time. My first thought was to just add a tag to the player but I don't know if that is a good method or not.

[orchid gazelle]

Does this also work for for example nms EntityZombies?

[orchid gazelle]

Are the abilities persistent or do you wanna lose them at server restart?

[dry yacht]

These are bukkit interfaces, nms classes will not implement them.

[orchid gazelle]

Yeah thats what I thought

So that will not work for custom mobs

If another plugin is using custom monsters, this will be a problem

If its the same plugin with custom monsters, you can just have a master method and then register all your mobs to it

[remote swallow]

i read custom monsters as something very different to start with

[orchid gazelle]

Ehh not that unrealistic that any other plugin uses them

[dry yacht]

We got something way cooler tho, IMonster.

[orchid gazelle]

Sheeesh IMonster

[dry yacht]

No idea at which versions this is available tho, as I never used it, xD.

[orchid gazelle]

Same

[dry yacht]

Oh, no, that's not how that works. If you only work with the bukkit API and you query the world for entities, bukkit will return you with a wrapper which then again works with it's own interfaces.

[orchid gazelle]

Custom monsters = nms

[mighty aurora]

I mean they should last through server restarts but some of them I haven't set up to be that way yet.

[orchid gazelle]

Then you got to use some data storage like PDC

Or if you are planning to code a complex PRIVATE system anyways, you can use a database

[dry yacht]

NMS is the whole foundation, so that's not going against what I said. If you have Plugin A which creates a custom NMS entity and adds it to the world and Plugin B queries the world's entities through bukkit, it will get a bukkit Entity wrapper with it's handle pointing at that custom NMS entity. Bukkit interfaces will work on that wrapper.

[orchid gazelle]

Wow I did not know that it would work with that

So if I use getHandle I just get the custom nms entity again

[dry yacht]

Right exactly! :). Bukkit just has a thousand different hooks and wrappers, but still has to operate on NMS, as that's the true workhorse.

[orchid gazelle]

Thats insane

[dry yacht]

I also didn't know about all of it's inner workings for like the first two years I developed plugins. The basics are the following: You can download an obfuscated server.jar by using mojang's version manifest JSON for each available version there's a client for. In the early days, the team had to manually deobfuscate and create their own mappings, nowadays mojang kindly enough provides them for us. Then, they would go into this codebase and add their custom code (event calls, wrappers, injections, ...) until the whole bukkit API was supported and working. Then they basically run diff and create difference files, which later again can be applied by the user locally, which avoids having to share modified mojang code (illegal, due to licensing).

Bukkit is an API, CraftBukkit is it's patch-style implementation. But at the end of the day, NMS is and always will be the server, as it's immensely complex, huge and cannot be open-sourced due to trademark bs.

It's crazy if you think about what this community is actually pulling off, lol.

[orchid gazelle]

Its crazy how much is behind a quite "simple" minecraft plugin

[quaint mantle]

is there any way to modify the code of the minecraft server.jar or even spigot server.jar, but with full access to every .java file

[remote swallow]

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[remote swallow]

?contribute you dont need the cla or pr stuff but this tells you waht to do

[undone axle]

You can find information about contributing to Spigot at the following links:
https://www.spigotmc.org/wiki/cla/
https://www.spigotmc.org/wiki/guide-contributing-to-spigot/
https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/README.md
https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/CONTRIBUTING.md

[dry yacht]

Just goes to show that if a community truly loves a game, it will be modding it, no matter the obstacles ahead.

[quaint mantle]

excuse my lack of knowledge but what is cla and pr

and which of those 4 links XD

[remote swallow]

pr = pull request

cla is required to contribute to spigot

the 3rd is what you need

might need 4th

[orchid gazelle]

CLA is basicly a legal thing so the copyright allows spigot to hold your code or something I think when PRing

(Correct me if im wrong)

[remote swallow]

?cla

[undone axle]

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

[remote swallow]

that explains it

[quaint mantle]

so the contributing thing will straightup let me compile a server jar. will that require me to actually give the jar to spigot?

[dry yacht]

Well, BuildTools has to build that stuff from the "OEM" obfuscated server.jar locally, so you could intercept it's stages and add your custom code to it, while having full access.

Don't know how easy this will be, as buildtools seems kind of restrictive (with applying unofficial mappings for example).

[remote swallow]

no

you can edit your code and use it

i just send the contribute link because it has the docs you need

?stash what you need mainly is stash been as it has spigot code, and https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/README.md

[undone axle]

https://hub.spigotmc.org/stash/

[dry yacht]

Yeaaaaah, these links are a good start, but oh boy, if you can actually understand the whole chain which pulls this compilation off from only reading that, then I have to take my hat off to you.

Looking into the source of BuildTools is a great hands-on start, but heads up: It's spaghetti-code... lol.

[quaint mantle]

do I need to do these

[remote swallow]

?dmca is the entire reason the cla & stash exist

[undone axle]

An unofficial explanation of the DMCA can be found here: https://www.spigotmc.org/wiki/unofficial-explanation-about-the-dmca/

[remote swallow]

nah

[quaint mantle]

or is that just if i want to send the final jar to spigot

kk

good cus i dont want to wait 24h

[remote swallow]

thats just if you want to contribute the code you change to the project

[mighty aurora]

Whats the best way to learn NMS?

[river oracle]

?tas

[undone axle]

https://tryitands.ee/

[remote swallow]

thats pretty much it

[river oracle]

legit try and see

[remote swallow]

just try and make something

it works or doesnt

?nms is a help for getting setup

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[river oracle]

@echo basalt has a forums post about it that has some useful info, but that does by no means cover most of it

[mighty aurora]

I don't even know how to setup NMS...

[river oracle]

.

read that article

[quaint mantle]

i notice this guide uses BuildTools, but i was hoping to use every class in the server jar, not just the ones buildtoolos shows from NMS

[remote swallow]

you would get remapped mojang from that

and importing spigot gives you every class you need

unless you want to use obsfucated nms stuff

[quaint mantle]

that falls into the category of every class in the server.jar

[dry yacht]

BuildTools of course has to include every single NMS class, as the final output jar has to be a fully featured minecraft server.

[remote swallow]

why would you want obsfucated nms

mojang released there obfuscation map, there is no reason to use obfuscated

[quaint mantle]

except im dumb and need every step drawn out for me

or maybe because i should go to sleep soon and im tired

[remote swallow]

https://nms.screamingsandals.org

theres that too

[quaint mantle]

is there any way i can straightup download a zip folder with full deobfuscated decompiled code with a build.bat file (or an equivalent build file)

[dry yacht]

If you just want to understand the process of obfuscation first of all, you could try the following: download the latest server.jar from https://minecraft.fandom.com/wiki/Java_Edition_1.19.3, as well as it's obfuscation map (for the !server!). Then download enigma deobfuscator, build it and run the swing build (easiest to use). I think that recent versions of server.jar are a bootstrapping type of wrapper which have the real deal inside of META_INF, so you have to unzip the outer jar and extract the inner jar. Open enigma, load the jar as well as the obfuscation map as type proguard, let it run and save the jar. Now you can view deobfuscated NMS code without any other additions and play around with that.

[dry yacht]

But well, no, due to legal bs.

[quaint mantle]

is it possible to get that?

with multiple steps

[dry yacht]

Yep, it is, if you basically mimic BuildTools behavior on your local machine and skip the final compilation step.

[quaint mantle]

like i want all the nms and mojang classes

[dry yacht]

I don't know enough about BuildTools, maybe it caches that result somewhere and you could actually get your hands on within the next few minutes. I find it so immensely unstructured and unclear that I avoided thinking about it for the most part.

[quaint mantle]

am i allowed to ping md 5 they were talking earlier to me about this

they happened to bein this channel

idk if we can ping

[eternal oxide]

no

[quaint mantle]

sad

[dry yacht]

To be completely honest, I think you have to go through this yourself. It takes discipline and time, but you'll learn a ton.

[quaint mantle]

i really want a way to change all the NMS and com.mojang classes to my liking

ill figure it out tmrw

rn im tired

lol

[dry yacht]

Since I also need a solution soon, I can maybe provide you with some of the utility scripts I'll come up with.

[quaint mantle]

but one big problem is that intellij cant find uses for some of the classes in com.mojang

but obviously theyre used

like duh

[dry yacht]

If the codebase compiles, the AST and symbol solver in IntelliJ should be able to find declarations, uses, inheritances, etc with ease.

[dry yacht]

This functionality is pretty basic and should be supported by most IDEs.

[quaint mantle]

i must be using the wrong folder

i decompiled a jar file i found at C:\Users\USERNAME\.m2\repository\org\spigotmc\minecraft-server\1.8.8-SNAPSHOT

and buildtools didnt show all those classes

but now it cant find the uses

cus theres no like pom.xml

and proper project set up

its just a decompiled jar

[dry yacht]

Yeah, all of this is pretty confusing. I also don't feel like going into the rabbit hole today, but as soon as I understood how to properly work with that myself, I'll let you know.

I still got a huge idea ahead where i need decompiled and at least partially remapped code from 1.8-present, so I need to automate generating patched source anyways.

[remote swallow]

the code is all on stash, running bt with remapped/mojang profile would add that jar to your maven local

i dont think you can get decompiled & deobsfucated code pre 1.14

[river oracle]

💀

You won't recieve much support for 1.8 here

[dry yacht]

Decompiled always, deobfuscated partially, because the community has worked on mappings to make the patchwork easier.

[river oracle]

It's legacy as fuck

[remote swallow]

well yeah

[dry yacht]

That's called nostalgia, most people don't get it.

[river oracle]

No people still use a super outdated version for strictly pvp

9.9/10 people don't care about nostalgia

[dry yacht]

Because it was just better, in every way.

[river oracle]

You can simulate it using plugins

[dry yacht]

Not just about pvp, you can easily get the same style of pvp on latest.

But all that clusterfuck of so called "new features".

[river oracle]

If you don't like how current plugins do it make your own

[dry yacht]

I don't actually play minecraft, but thanks for giving me that freedom, lol.

[echo basalt]

pings me
doesn't link tutorial

[river oracle]

Lol

My bad

Musta gotten distracted

[remote swallow]

does bungee not have a way for me to create items?

[slate coral]

Hey Hey Quick question as the PlayerPickupItemEvent doesn't get fired when trying to pickup items but with
an actual full inv. What would be the most efficient way to check when players try to pickup items?

Do I have really to compare the current location of the player and the item which is laying on the ground?

Thanks in advance!

[remote swallow]

if there inventory is full pretty much, because the item cant even be attempted to be added to their inventory

[dry yacht]

What are you trying to achieve? Maybe there's a more elegant solution out there, which we can only think about if you share your goal.

[slate coral]

Goal is if the inventory is full and he is trying to pick it up its getting stored somewhere else instead, so "picking it up" but not to the player inv @remote swallow @dry yacht

[remote swallow]

idk if this is possible but you could see if theres a packet to send inventory change, you could have a fake empty slot that could pick items up, except that would only work if 1 type of item was on the floor. or you just listen to move event and check if theres any itemstack entities on the floor where player is

[pseudo hazel]

what do you mean by create items

[remote swallow]

i couldnt create ItemStacks, then i realised i couldnt create inventories without packets so i just made it have a spigot half

[dry yacht]

Going through all items and calculating the distance squared to a player while having to compare against known pickup suction values would just be a nightmare and pretty wasteful, in my opinion.

Seems like NMS already has a method on EntityItem, which checks if it's being touched by a player. We would only need to instrument that to fire some hook. But well, it's starting to get complicated again, ^-^

[slate coral]

Anyways a big thanks for that! 🙂

[dry yacht]

I'd love to solve that issue tho, it's just that I don't know if I still have the mental capacity left today (pretty late already, xD). There has to be an elegant solution, I'm quite confident about that.

[slate coral]

yea think so xD May we can find something as I have something pretty neat in mind about a feature for an upcoming plugin

Kinda bulling me rn haha

[dry yacht]

I feel you, it sucks to see the solution right ahead but not being able to hold it in your hands because of stupid limitations due to legal bs and the ego of humans. Well, I'm sure we'll be able to hook into this somehow.

[robust zenith]

Somebody wants to help me doing a call with a fantastic BlockBreakEvent plugin?

hey guys, i want to create a world with only one pillar per chunk but there is a problem. the structures and the trees are generated after my custom generateNoise function. how can i fix this?

[humble tulip]

Are you using a ChunkGenerator?

[dusky saddle]

Yup

[humble tulip]

override shpuld generate structures

And return false

[dusky saddle]

But I want Structures but just part which is in the Pillar

@humble tulip

[humble tulip]

Well how do you know where pillars are?

Actually this isn't my forte

Sooo

Chunk coordinate 0 0

[slow arrow]

what does Bukkit.getOfflinePlayer(String name) return if there is no minecraft player with the username?

[remote swallow]

null i would guess

[slow arrow]

apparently its never null

its annotated with @ NotNull

[remote swallow]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Bukkit.html#getOfflinePlayer(java.lang.String)

guess it wont

[slow arrow]

is there some way to tell if the player is an actual player?

[remote swallow]

you could probably attempt to get their uuid

[humble tulip]

Wdym?

An actual player?

[remote swallow]

because if a name doesnt associate with an mc account it shouldnt have a uuid

[slow arrow]

true

thanks.
The plugin isn't ready to test yet but that sounds like it should work

[ivory sleet]

an OfflinePlayer object simply

[dark karma]

hi, i'm just messing around and i created a listener that listens for a player join or a chat and sends a message. before all the messages sent by the plugin there's this weird little character. does anyone know what this is or how to get rid of it?

i don't think i have image perms but here's a better screenshot to show the issue

https://wa.wtf//7efc62ccab4ce488bb5faa39a9a6ed5e

[remote swallow]

thats the 1.19.1 chat reporting thing

it says if the message is secure ornot

[dark karma]

ahhhh okay thank you

[dark karma]

i just realized i can hover over it and see that lmao sorry for wasting your time

[remote swallow]

np lol

[spring pike]

@dry yacht I found a solution that works for me. My server is a soup pvp server, and it is usual to reduce the damage by 25% on these types of servers, to make the players able to survive stone sword damage without their fingers falling apart. My method of doing this was by only reducing the damage if it is above 2, which didn't count in these annoying crit-double hits, which happened to interestingly always be 1 heart, and then instantly the normal attack damage after.
I compared it to a fight I did on another soup server, and realized that this also happens there, I just didn't notice before. Instead, the "pre-damage" is only .5 hearts (or .75, if you will). So, I changed my method to only apply *.75 damage when the player has an item that deals above 1 damage in their hand, and when the event Cause is ENTITY_ATTACK. Sure, not a real fix, but my desired behavior anyways.
Some things turn out to be simpler than they appear to be lol

[quaint mantle]

hi

is there a way to cancel all lighting updates when adding or removing blocks with plugins?

[tardy delta]

Nms

Check the forum, im sure there is a post

[ocean hollow]

hi guys, what can this error say?

[tardy delta]

that is empty check isnt needed

[tardy delta]

content is null?

[somber berry]

Help? What am I doing wrong

[ocean hollow]

oh, thanks, sorry path was written incorrectly

[zealous osprey]

Specifically from explosions of everything? Cause there's also a BlockChangeEvent or smth similar

[somber berry]

All explosions, the blockbreakevent is working but I cannot figure out how to make those blocks from the list invincible to explosions

[zealous osprey]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/block/BlockExplodeEvent.html#blockList()
You might need to use the blockList() instead of getBlock()

Also a handy thing is, to make early escapes from loops. You can use continue; to skip the step in the foor-loop or break; to just stop the for-loop
