help-development

[rotund ravine]

It's quite a big grid tho

[pale hazel]

Okay, that makes more sense. I am bit new to using an API so all of this is overwhelming

[dry yacht]

My lord, how can there be such controversy to such a simple API, hahaha :,D. I love it tho, keep on going, xDD.

[rough drift]

I gtg soon though

Tomorrow I'll have the API sort of usable

Going now though

[rotund ravine]

huh

why are yo ueven setting it btw?

The default stuff is already that.

[sterile token]

Will it work on 1.7?

[rotund ravine]

If you transpile it yourself lol

just turn it off in settings

[sterile token]

No, why? Apis are designed to make things simplier, so there i dont see it viable

[dry yacht]

It sure is, you have to take your time and just open up a new playground plugin to experiment around with this stuff on a localhost. It makes a lot more sense once you know what the API actually does behind the scenes.

[rotund ravine]

Cause we only build for the newest version obviously?

He is gonna make a pull request to spigot itself

not a plugin

[sterile token]

As far as I know, it has been proven that companies that only target one sector have lower average profits compared to those that offer their products to the entire public, dont you think it?

[dry yacht]

With that it's doomed for mediocrity already. Just don't do anything fancy, proper or version-independent, or you get denied.

[rotund ravine]

shush.

[sterile token]

Na haha dont get mad Jan, im just fucking tho because i used to be 1.8 developer. Now only +1.16 comissions

[vocal cloud]

Still gotta work on my @Since stuff lol

[gleaming grove]

They does, great flawless Bedrock version is made with C++

[sterile token]

oh nice tho

What properties will you put for a Group object? So far i have name, weight, prefix and nodes

[dry yacht]

Group object? Parents are missing, if I understand you correctly. And what do you signal with weight?

[sterile token]

Group for managing permissions
Their priority (weight)

[dry yacht]

Yeah then, parents, most definitely. And a list of negative permissions which are subtracted from them and stop propagating down the inheritance chain.

[dry yacht]

I'd actually call it priority then, not weight tbh, as that's kind of confusing. Weight is a known term in computer science.

[sterile token]

Okay, can you explain the propagtion part?

[sterile token]

ok, thanks ill take your recommendations

[dry yacht]

Well, if a group has a parent, it inherits all of those permissions in it's #hasPermission check, but it does not own those permissions itself. If you have Group C inheriting from group B which inherits from group A and group A gets my.example, B gets -my.example, C will not have my.example, as B blocked it. B will also not have it.

[sterile token]

Do you think this way of saving/loading is correctly? or will be any better

[vocal cloud]

Mongo

[quaint mantle]

How I know plugin's RAM usage?

[sterile token]

Why? Because they will use it on a large network

[dry yacht]

I have no idea what that's about without extra context, sorry.

[dry yacht]

Well, because it perfectly fits a relational model, but sure, pick your tools, you are free to do so.

[sterile token]

I mean not only have to sync between a network i have to sync around different proxies 💀

Its not so simple tho

HAHAHAH

[quaint mantle]

Lol

[vocal cloud]

Use one global sqlite file /s

[halcyon lintel]

Can someone help me im tryna make a server with a strength 2 area basicly when ever u go inside the area u get strength 2 but if u leave it goes away if that makes sense can someone help me with the script pls

[sterile token]

Is SQL more scallable rather NoSQL? How much? Are there unit testings?

[dry yacht]

Are you planning to have all servers access the DB and use transactions to synchronize, or do you want to pass around info through messaging channels, as in an in-memory event database?

[sterile token]

They told me i must use something like RabbitMQ

[vocal cloud]

Well, think of it as you don't have to load an entire object everytime you want something. You can query specific things instead of needing to pull entire documents

[sterile token]

Well, mongo allows that tho, that why it contains Filters

[vocal cloud]

But it's still loading the whole document

[sterile token]

I mean im not wondering to fuck with this, just understand why most people use Sql

[vocal cloud]

Assuming you're mapping PoJo

[sterile token]

Im not using Pojo´s so far, because it cause me lot of issues

[vocal cloud]

SQL allows you to get only the data you need from queries

Since it's relational it also works better for things that require relationships

[sterile token]

I must use RabbitMQ, but i dont like as much a Redis because Rabbit doesnt have the ability for catching data in memory, its more like a data broker

[dry yacht]

Must? Wow, that sounds harsh, xD. You can easily write your own little protocol, you just have to deal with acknowledgement and so on then.

[dry yacht]

Mongo does too, IIRC? You should be able to select individual fields using a query on any good database implementation.

[sterile token]

Yeah, but they told not to reinvent the wheel when its already invented, also it wouldnt so optimized as a software already created and which has years of experience

[dry yacht]

Sure thing, it's a good choice.

Just wondering how you got into such a massive project.

[sterile token]

I mean i dont discard it tho

Such a big history hahaha

[dry yacht]

Because, not trying to be mean, but I think you might bite off a bit more than you can chew with that implementation. LuckPerms (i think) also does this stuff, and it's a huge ass sophisticated project. You might burn yourself out in trying to create something similar.

[sterile token]

I join caused a Russians recommend me in that project but i never realize until the owner contacted me and told me if where interested

[dry yacht]

It does? Damn you, point taken...

I mean... well, that doesn't dictate how one has to design their API, by no means.

[sterile token]

Yeah i told them many times, they can use perfectly, but they excuse was "we wanna have every plugin as custom as we can"

And my face was 🤡

[dry yacht]

I think you should support both, as the tab instance knows it's width, so why make caller have to use their brain to calculate stuff...

[gleaming grove]

Like if you want to use RabbitMQ you will have to implement event driver architecture

[dry yacht]

Just trying to give you a heads up. Believe me when I tell you that you'll probably burn out and be sad in the end. I've still got a big ass project on my disk where I created a whole server from scratch, used nothing existing, burned out and felt like shit.

[gleaming grove]

It's harder then Http or direct push to database because you will not get response if data has been saved to database

[sterile token]

What is scratch?

[dry yacht]

From scratch just means from the ground up without any libraries.

[dry yacht]

Or a beginner's "programming language", lol.

[sterile token]

oh ok

Dont bullet me im not native speaker

[trim creek]

More likely a game engine for 10 years olds

[dry yacht]

Well, you'd have to design that yourself, I think. The bungee-server should write to the DB while all sub-servers only keep state based on received events in memory. But I guess you'd always need an ACK from the bungee instance, otherwise you'd need to throw up all along the call-chain. Basically implementing transactions.

[dry yacht]

Me neither, no worries, I have a hard time with human languages too.

[sterile token]

Nice, german?

[dry yacht]

Austria, xD. But yes, my native language is German.

[zealous glen]

Can we just delete this please

if I get hacked idc

this is the most annoying shit at least add google authenticator support

[proper notch]

Other people care when users upload malware to spigot

oh also, there is google authenticator support....

I legit use Authy on my account

Hover on your profile -> Two-Step Verification -> Verification Code via App

[zealous glen]

then they can enable it

I'm not an idiot who downloads random shit

bro why are you typing to me do you have aspergers?

I know its catered to children like you 🙂

[dry yacht]

Nope. You also don't have to send raw bytes over HTTP just because TCP does. It's called abstraction. If I, as an API designer, think that rows and cols are a better fit, I can translate internally without letting this detail bleed through.

But please, let's just settle on our agreement of adding both slots and grid methods, xDD

[rotund ravine]

It has?=

What are you on about

google 2fa is supported.

[dry yacht]

lrighty, I'mma head out.

[zealous glen]

Yes I just noticed it now after I logged in

[ivory sleet]

Yeah both are useful

[vague swallow]

Hello,
This is my code which is supposed to move the entity to the players position with a vector which is perfectly working, when both locations have the same y-coordinate. If not then the entity flys way higher than the player is and also far beyond the players location. Does anyone have an idea why and what I can do to prevent this?

Entity e = player.getTargetEntity(distance(p), false);
assert e != null;
Location loc = e.getLocation();
Location target = player.getLocation();

int aX = target.getBlockX();
int aY = target.getBlockY();
int aZ = target.getBlockZ();

int bX = loc.getBlockX();
int bY = loc.getBlockY();
int bZ = loc.getBlockZ();

int x = aX - bX;
int y = aY - bY;
int z = aZ - bZ;

Vector v = new Vector(x, y, z).normalize();
v.multiply(loc.distance(target)/2.7);
e.setVelocity(v);

[dry yacht]

Hmmm, those last three lines seem kind of weird to me tbh. You're normalizing the vector, thus dividing each coordinate by it's length (the distance), then multiplying by the distance divided by 2.7 again. Instead of normalizing, you can just divide by 2.7. That's not solving your problem, but at least helps readability, first of all.

[atomic swift]

was EntityPickupItemEvent switched to PlayerPickupItemEvent

or did it just not exist in 1.8.8

[gleaming grove]

Shouldn't v be inverted? if player has y 500 and an entity 400 then y is -100 but should be positive to reach player position

[vague swallow]

because IntelliJ warned me that it could be null but I checked earlier if it was null or not. It's just a formality

[dry yacht]

I have forgotten how minecraft applies velocities, but from knowing that velocity is speed in m/s, I guess it applies 1/20 * velocity to the target's position at every tick, to apply the whole vector every second. You'd have to consider drag as well, which is dependent on the distance travelled.

What you want to accomplish is move the entity along the vector between the player and itself (end - start, as you correctly calculated). The simplest way of doing this in a linear motion, you could teleport the entity along the path this vector dictates by multiplying it in the range of [0;1] in a loop, taking step sizes in a way that you have consistent velocity no matter of distance. This teleportation could be performed on every tick, as it's not really any more expensive than sending out move packets (which the server essentially does) every tick.

Velocities in minecraft always weirded me out tbh, maybe I'm just stupid.

[vague swallow]

you mean the entity has y500? because the target is the player. But if the target was below the entity then the entity should move downward

[gleaming grove]

Ye

[vague swallow]

so you're suggesting to make a scheduler?

and teleport the entity every tick along the vector?

[dry yacht]

Why tho? They're calculating end - start, which gives the vector from (0, 0) and the length and direction of the distance. Applying that to the position of the entity will result in the vector's pointer to be exactly on the target.

[dry yacht]

Right exactly. Because - in essence - adding a velocity to it does nothing else, but you have one big issue: simulated physics, which works against what you want to accomplish.

[dry yacht]

With a scheduler you don't have to compensate for physics.

[vague swallow]

I'll try that but how do I teleport an entity along a vector?

[dry yacht]

Not at all meant in a mean way: how good do you know vector math?

[vague swallow]

I didn't really understand it tbh XD

but that would instanly teleport the entity to the player

[torn badge]

loc = playerLoc + (target - playerLoc) * Range(0;1)

[dry yacht]

Let me come up with a quick example for you, I know that it can be hard to understand if you're not into math as a hobby and haven't done it in a while. I'll get back shortly.

[vague swallow]

thanks

[vague swallow]

thanks!!!

[torn badge]

playerLoc being the start position all the time

Location playerLoc = player.getLocation().clone(); for (double t = 0 ; t <= 1 ; t += 1/20D) { Location loc = playerLoc.add(targetLoc.clone().subtract(playerLoc).multiply(t)); player.teleport(loc); }
Written on my phone

But in a scheduler

Because that would just teleport to the end within the same tick

[echo basalt]

oh god please use actual variable names

[zealous scroll]

Is there a way to check if an inventory was opened to the player by a plugin? I'm trying to replace crafting UIs from crafting tables but not from commands owned by other plugins

[echo basalt]

but yeah you basically want to lerp between 2 points

[dry yacht]

I'd just be very careful with calling clone all the time. You're generating a hell load of new allocations for no good reasons. It's a shame that all of these utilities mutate in-place. And second of all, your step-size does not compensate for distance and thus won't yield a constant velocity for all distances.

[vague swallow]

thanks very much for the help!

[torn badge]

t is a common variable name for lerping

In C#

[dry yacht]

Which can actually be harder to implement efficiently than one might think on first glance, lol

[echo basalt]

one-letter variable names should be reserved to x, y and z

[torn badge]

What about i, j, k?

[echo basalt]

nope

[zealous scroll]

Inventory#getLocation is not null even when it is a virtual UI

and Inventory#getHolder is always the player anyway because the crafting table cannot be its holder

[echo basalt]

i -> index/iteration

j and k make no sense

[dry yacht]

Just gonna take a few minutes as I actually want to give you something that's efficient and understandable.

[vague swallow]

I really appreciate that, you can also dm me if you want

[dry yacht]

I'm just going to post it here, as it'll be a general solution and might help others too (if they ever manage to find it, haha).

[vague swallow]

XD

[torn badge]

https://www.oracle.com/java/technologies/javase/codeconventions-namingconventions.html

[echo basalt]

Variable names should be short yet meaningful.

[torn badge]

Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters.

[echo basalt]

Each company follows different code styles

For example, Google Style

[torn badge]

Yeah okay but it’s still a Oracle convention

And I have seen this in all kinds of programming languages

[torn badge]

That’s right, if you want a constant speed for different distances. That method allows to easily set a duration, so it depends on what you want

[dry yacht]

Which method do you mean? Just having a hard-coded step size doesn't allow to set a duration, as the duration is depending the distance travelled.

[torn badge]

t += 1/duration

[wet breach]

?conventions

[undone axle]

https://www.oracle.com/java/technologies/javase/codeconventions-namingconventions.html

[dry yacht]

Ah yeah, sorry, I misunderstood that part. Of course the duration is choosable, depending on the delay between iterations.

[torn badge]

We had that already

[wet breach]

yeah but the bot is better

[torn badge]

True

[vague swallow]

Why is player.getTargetedEntity() only returning LivingEntities and no other entities? Is there a way to return all targeted entities not only the LivingEntities?

[chrome beacon]

That method is not part of the Spigot API

[hazy parrot]

Guy from whereami gif making mistake again

[vague swallow]

Oh that's why I didn't find it lmao

[dry yacht]

You could try this approach, although I haven't actually tested it myself: https://paste.md-5.net/fanaruyoci.cs

[vague swallow]

nonono don't mention it

[dry yacht]

Because the LivingEntity is the most abstract type there is for entities which still makes sense in this context. You have to check for specific entities using instanceof yourself. But you get all entities which are living.

[dry yacht]

Oh, you probably mean things like ItemFrames, huh? I actually haven't used that API ever, I think when I needed something similar I actually casted a ray.

[vague swallow]

bro this helped me A LOT

Thanks so much

[humble tulip]

Has anyone benchmarked using reflection with cached methods and classes?

[dry yacht]

I actually hope that it works, because it has been a long ass time since I had to think about all of that, xD. Love to help, as I actually know exactly how it feels to be overwhelmed by things like these.

[dry yacht]

Probably not, so we should! :). How funny that I just yesterday thought about doing this, lol.

[young nimbus]

Hi, i bought a server a few weeks ago, everything worked fine. Since today when i run a command of a plugin that i wrote, after 1 minute my server crashes and gives the error Startup script './start.sh' does not exist! Stopping server. Can someone help me? I didn't made any changes on the server, just uploaded my plugin

[civic apex]

i implemented cached reflection into my plugin today

[chrome beacon]

Send the server log

?paste

[undone axle]

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

[humble tulip]

Send your code as well

Methinks infinite loop

Any guesses?

[chrome beacon]

Yeah probably

[dry yacht]

Btw, just to make sure, what exactly are you guys define as cached reflection?

[civic apex]

i cached the fields/classes/methods

so i dont have to get them each time

it should be faster

[humble tulip]

Yes that

[young nimbus]

Logs: https://paste.md-5.net/watiqiwuve.md Code: https://paste.md-5.net/rufuzufaza.java

[dry yacht]

I only use cached reflection then, as my library searches all dependencies (class, method, field, constructor handles) in the constructor of the class trying to work with them so the plugin won't even load if we're not compatible.

[hazy parrot]

Doesn't that java do by default?

[civic apex]

but do you load them each time?

[hazy parrot]

Or its only kotlin

[civic apex]

i dont call .getDeclaredClass(classname) every time

[young nimbus]

My command runs titles, after the 6th Title (1minute delayed) it crashes

[civic apex]

i dont think getdeclaredclass has cache implemented

[dry yacht]

I doubt that it's much worse than direct access, as a Field should basically provoke a field access instruction with the overhead of a method call, right?

[humble tulip]

Well idk how reflection works internally so i cant say but I'd assume so

[civic apex]

and for fields i have static fields set to accessible

(when needed)

i know for a fact mine has to be faster than non cached

[rotund ravine]

Kotlin doesn’t either

Unless u tell it to

[dry yacht]

I also only assume it, but it would be stupid otherwise. I don't get why "reflection is sooo slow" should hold true, as it's perfectly optimizable. You basically wrap the field access instruction in a method called set/get.

[rotund ravine]

It has the lazy access

[civic apex]

because to get some classes i have to perform operations with streams (or for loops alternatively), and doing that each time is slower

[dry yacht]

Depends, the JVM might cache itself. But it's definitely far more sane to do so yourself, yes.

[rotund ravine]

Using something like reflectasm which generates bytecode that runs, it goes wroom wroom

[humble tulip]

Don't sleep a thread

[civic apex]

maybe, but the stream/for operations will still be done each time

[dry yacht]

Hahahaha :,D. Damn, never heard of that, need to look it up asap, lol.

[civic apex]

i call .getdeclaredmethods then filter

[young nimbus]

what should i do either?

[civic apex]

discord?

[humble tulip]

When you sleep a thread, the server thinks the thread is no longer responsive

[civic apex]

how have i not read my own message

[young nimbus]

damn

[rotund ravine]

https://github.com/EsotericSoftware/reflectasm

[humble tulip]

What do u want to do?

[young nimbus]

i am such a idiot haha, bought 5gb extra ram haha

[humble tulip]

Do something x ticks later?

[dry yacht]

Same, just differently. https://github.com/BlvckBytes/BBReflection/blob/main/src/main/java/me/blvckbytes/bbreflect/packets/InterceptorFactory.java

[rotund ravine]

It's used heavily in this @dry yacht https://www.spigotmc.org/resources/twerktree.35496/

[young nimbus]

yeah

[humble tulip]

?scheduling @young nimbus

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[young nimbus]

thanks

[civic apex]

anyways, im having a problem setting a player's gamemode

[dry yacht]

Wow, what a plugin name, xDD. Going to have a look rn.

[dry yacht]

What's the problem?

[civic apex]

its not working

[dry yacht]

...

[civic apex]

i run this on PlayerJoinEvent

(debug stuff)

[hazy parrot]

Why don't just... Player#setGamemode or smth

[civic apex]

this is the output, and the gamemode is survival

[civic apex]

its not working, so i used the nms method which has a return type (boolean)

the api just calls the nms method and ignores its return type iirc

[spice shoal]

Guys , can it work??

`import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;

    return null;
}

}`

[dry yacht]

<insert your favourite indent hell meme here>

[civic apex]

the weird thing is

[dry yacht]

No, never, actually.

[spice shoal]

why? pls help me

[civic apex]

as oggm (original gamemode) is survival and the gamemode im trying to set is spectator the only way "gm" could be false is if PlayerGameModeChangeEvent is cancelled

[hardy garnet]

Hey guys! i'm having an issue with world creator. When making the new world, players end up being disconnected due to it taking too long. Is there a way I can prevent this

[civic apex]

the thing is i only have my plugin, which never cancels that

plus after that p.getGameMode is somehow spectator, which shouldnt be the case if setGameModeForPlayer returns false that way

[dry yacht]

Man, that hurts my brain

How is something that simple not working

[humble tulip]

??

How

What mc version?

[civic apex]

idk

[rotund ravine]

Looks great

[humble tulip]

Wait you mean the world takes so long to load?

[hardy garnet]

In actuality its loading an already created world, but while its creating the spawn it takes too long and players get disconnected

[dry yacht]

Just joking btw, that's normal code, xD. Not one of those "never-nesters", although I love unnested code where ever possible.

[civic apex]

haha some of my old plugins have way more

[rotund ravine]

I should probably have used something other than triple, but was too lazy.

The names of the classes are also a bit weird

[civic apex]

you can remove the newlines after the first two for loops

if you remove the braces

its not pretty

but ¯_(ツ)_/¯

[dry yacht]

Btw, what the hell is a ServerPlayer

[humble tulip]

What's the actual solution to triple for loops

To orevent nesting

[humble tulip]

A server player

Duh

[civic apex]

mojang mapped version of the nms version of craftplayer

[torn badge]

NMS Player

[civic apex]

which i dont remember the name of

[dry yacht]

Very broad question to be honest, completely depends on what you're trying to accomplish. Almost unanswerable.

[rotund ravine]

Probably old EntityPlayer

[civic apex]

yes that

[dry yacht]

Oh, okay. I'm just still stuck in 1.8 times, sorry, xD.

[torn badge]

Got it after the 10th try 😂

[spice shoal]

why?

[civic apex]

me too lol

[rotund ravine]

I am drunk of course i type badly

[dry yacht]

This doesn't return a boolean, what version are you on?

[torn badge]

I was cheering for you to do it

[civic apex]

hey now ive realised my intellij theme is gone

i knew something felt wrong

[dry yacht]

That was a joke, sorry for the sarcasm involved. I have no idea actually, as I'm about to pass out after multiple nights of next to no sleep and a full day of coding. Sorry, but I cannot help you right now, you ask way too much with way too little context and explanation.

[civic apex]

thats the craftbukkit method

[dry yacht]

Hahaha, yes, that's the theme I've banned from ever coming back.

[civic apex]

im calling .a()

[spice shoal]

oh ok , np

[civic apex]

just the mojang mapped version

[civic apex]

which in mojmaps is setGameMode

[dry yacht]

Oh, sorry, I really need to sleep soon. Just want to check out how that boolean is defined.

Oh come on, .a is a void too

What version are you on, 1.19?

[civic apex]

huh

[civic apex]

1.18.2

im a certified 1.19 hater

[torn badge]

@civic apex Delay it by 1 tick

[civic apex]

i tried, still didnt work

sometimes it did

didnt test too much

[dry yacht]

Yeah, at 1.13 it's not a boolean yet, they changed that. I was on 1.13

[torn badge]

Then there must be something wrong on your side

Show your whole code

[civic apex]

._.

[civic apex]

wdym by whole code

[torn badge]

And please don’t use nms for setting a game mode 😂

Your entire listener

[civic apex]

its for debugging aisnduaybdawdmoia

[civic apex]

k

@EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Player p = e.getPlayer();
        recentQuitPlayers.remove(p.getName());
        if ((!Uhc.gameManager.isStarted()) || Uhc.gameManager.getAlivePlayers().contains(p.getName().toLowerCase())) return;
        PlayerDeath.setupDeadPlayer(p);
    }```

[dry yacht]

Hmm, depends on which path gave you the false

[civic apex]

uhc plugin yes

[dry yacht]

Are you sure there are no other plugins listening for events?

[civic apex]

not 100%, i only unloaded them with plugman and no errors

[dry yacht]

You did what?

...

[torn badge]

setupDeadPlayer sets the game mode?

[civic apex]

yeah

[torn badge]

Okay now try delaying that by 1 tick

[civic apex]

the gamemode set?

i already have previously

[torn badge]

Just the entire method call

[civic apex]

k

[torn badge]

And then show your entire setupDeadPlayer method too

[civic apex]

public static void setupDeadPlayer (Player p) {
        p.setHealth(20);
        p.spigot().respawn();
        Player teammate = UHCTeam.findTeammate(p);
        p.teleport(teammate);
        ServerPlayer sp = ((CraftPlayer) p).getHandle();
        Bukkit.broadcastMessage("oggm " + sp.gameMode.getGameModeForPlayer() +"\ngm " + sp.setGameMode(GameType.SPECTATOR));
        Bukkit.broadcastMessage(p.getGameMode().toString());
        new BukkitRunnable(){
            @Override
            public void run() {
                p.spigot().respawn();
                teammate.addPassenger(p);
            }

[torn badge]

You call respawn after setting the game mode

[civic apex]

does that set it to survival?

[torn badge]

Possibly

[dry yacht]

True that, but it still doesn't fully explain why the method returned false.

[young nimbus]

ugh i hate eclipse, i get an error in line 69, could someone look over it rq? https://paste.md-5.net/tulelorilo.java

[vague swallow]

why do you add him as passenger and not as spectatorTarget?

[humble tulip]

what's the error?

[civic apex]

idk

its different

[humble tulip]

ah

that's not eclipse

[dry yacht]

You cannot change a variable's value inside a lambda expression. It only captures it's value, but that's immutable then.

[humble tulip]

I'll send an example of how to do it

[young nimbus]

thank you, appreciate it

[dry yacht]

You'd need an AtomicInteger, which is a pointer to an integer, which you can then call incrementAndGet on

[rare rover]

Is there any good alternatives for teleporting an armor stand every 1 tick, im moving it up and down while rotating it

Make it look as smooth as possible

I could do 3-5 ticks ig

[dry yacht]

Btw, you're not stopping the task either. Return doesn't stop the task.

[humble tulip]

        Bukkit.getScheduler().runTaskTimer(Main.getInstance(), new Runnable() {
            
            int index = 0;

            public void run() {
                
                if (index >= titles.length) {
                    // We've displayed all the messages, stop the task
                    return;
                }

                String title = titles[index];
                String subtitle = titles[index + 1];

                // Display the title and subtitle
                player.sendTitle(title, subtitle, 1, MESSAGE_DELAY_TICKS, 1);
                player.playSound(player.getLocation(), Sound.ENTITY_EXPERIENCE_ORB_PICKUP, 1.0f, 1.0f);

                index += 2;
            
            }
        }, 0, MESSAGE_DELAY_TICKS);

[young nimbus]

thank you very much!

[humble tulip]

replace return with cancel()

also why are you doing index+=2?

[dry yacht]

Alternatives as in what? You could use move packets instead of teleportation, as that interpolates between positions on the client, which in essence makes it look more smooth again.

[humble tulip]

dont tell me you have titles and subtitles in the same array

[dry yacht]

Ah yes, the anonymous class, a classic! xD

[humble tulip]

have a title array anda subtitle array

[dry yacht]

What's wrong with that?

[humble tulip]

ArrayIndexOutOfBoundsException

[rare rover]

Okay, im just trying to make it as fast as possible

Aka performance

[dry yacht]

Why? As long as it's member-count is even

[humble tulip]

String title = titles[index];
String subtitle = titles[index + 1];

[humble tulip]

sure that work but it's clumsy

[dry yacht]

Yeah, then you could do move packets and step up the delay between moves a bit, but well... whether that's worth it? Or you send teleportation packets and go async, as you're not altering the world anymore.

[dry yacht]

Oh come on, it's common practise in low level languages. But okay, I get your point.

[rare rover]

Oh, bet okay thank you

[humble tulip]

low level languages

[chrome beacon]

Use a lambda expression

[young nimbus]

thanks @humble tulip

[humble tulip]

np 🙂

gn guys

gonna sleep

[young nimbus]

gn

[civic apex]

unrelated, but ive read that some times now and still dont get why i shouldnt use a static singleton

[dry yacht]

Basically because of coupling. You're locking yourself in.

[civic apex]

in bukkit development at least

theres one and only one javaplugin, and only one will ever exist

[dry yacht]

Passing a Plugin (interface) as a parameter doesn't couple you to a main class called "Main", it only couples you to bukkit's API. If you copy the file in another project called "Playground", you'll have to rename all "Main" symbols.

[civic apex]

but for the plugin itself its a non issue

di isnt more performant afaik

[dry yacht]

Almost none of the bad practises really are an "issue", as long as it works. But you do want to become a better developer, don't you? :)

[civic apex]

yeah but i see problems with di too

[dry yacht]

Don't think so, tbh. The compiler is very likely smart enough to notice the singleton pattern and optimize the method call out.

[civic apex]

not for the compiler, more for the mantainability

[humble tulip]

                ByteBuf newDS = (ByteBuf) pds.newInstance(Unpooled.buffer());

                writeVarInt(newDS, windownID);
                writeVarInt(newDS, windowType);
                BaseComponent[] component = new ComponentBuilder().bold(true).appendLegacy(ChatColor.RED + "Coool enderChest :)").create();
                byte[] newMsgByteArray = ComponentSerializer.toString(component).getBytes(StandardCharsets.UTF_8);
                writeVarInt(newDS, newMsgByteArray.length);
                newDS.writeBytes(newMsgByteArray);

                readPacket(newDS);

                Object newPacket = con.newInstance(newDS);

creating packets the wiki.vg way

[dry yacht]

Sure thing, have a smaller constructor but end up in couple hell.

[civic apex]

i've never seen it as "hell"

also i dont know if im going to need a plugin instance

[chrome beacon]

How often do you even have a massive constructor

[dry yacht]

Then you don't tend to write your own reusable libraries/modules.

[civic apex]

so if i dont i make the constructor w/out

[civic apex]

i mean thats true

[dry yacht]

Abstraction of logic requires dependency injection.

[civic apex]

i do create utils but per plugin

[dry yacht]

I know it for a fact, because that's how I thought too before I got into the more advanced architectures.

If a single class has a huge ass constructor, you're not segmenting it's responsibilities well enough.

And having many files in OOP projects is a shitty argument in my opinion.

[civic apex]

di only helps make it bigger tho

[dry yacht]

Yeah, because every number except than zero is bigger than zero, lol.

[civic apex]

thats not true

[dry yacht]

If you hate wiring constructors so much, use an auto-injector.

[echo basalt]

it's not even that hard

[civic apex]

whats that

[echo basalt]

type in your variables and alt+insert a couple times

or lombok

[dry yacht]

excuse me, every natural number.

[chrome beacon]

^^

;/

[civic apex]

yeah i do that

not saying its hard to make

i just dont like having to specify a plugin instance per constructor

[dry yacht]

A central registry where you register all your available dependencies and it invokes the constructors and matches instances for you.

[echo basalt]

then specify JavaPlugin

[civic apex]

ofc if i was writing a library i would do that

[dry yacht]

Not every constructor should need one. But there's no shame in taking one in, lol.

[echo basalt]

tfw your main has more "this" than actual words

[chrome beacon]

this

[dry yacht]

You gotta have the ugly parts somewhere. And if you wanna sweep them under the rug of runtime, use the registry and a java class scanner.

[limpid bloom]

Need a bit of advice, I am in a big project and I am making something to help do something faster and semi automatic, right now it’s a plug-in but I need it to be faster , problem being I am new to making plugins and kind of new to Java so while everything works, it needs to be faster , rn the plug-in can do an area of around 8mil blocks in about 3-4 seconds but when I need it to check an area of around 500m +, maybe up 1 billion blocks, well the plug-in needs to be better, rn when trying to do large areas the plug-in lags the server so much it crashes , rn it’s not asynchronous so it lags the server quite a bit, for every block in the area it has to check some blocks around it, about 12-24 blocks total and then it decides if it is changing the main block so a lot of checks , rn I am the crossroads, do I continue trying to make plug-in better and not crash the server when doing the volumes we need it too, segmenting the total area to do one after another (in game), or piggy back off of fawe and try to Learn and use craftscript , any help for either option or a different option that may be better .

[civic apex]

why are you in a big project if you are new to java and plugins?

[chrome beacon]

What's the command for load balancing again? I forgot

[echo basalt]

that's uglier ig

[chrome beacon]

Just split the scanning of blocks over multiple ticks so the server doesn't crash

[limpid bloom]

It’s a mc project, not a plug-in project, making plugins to replace old datapacks I had made, plugins are better and faster than datapacks.

[dry yacht]

D:

[civic apex]

oh

[echo basalt]

the plugin class is usually just like a central hub

contains trackers, managers and all

[civic apex]

whats a tracker

[echo basalt]

90% of cases it's just this

[remote swallow]

?workdistro

[undone axle]

https://www.spigotmc.org/threads/guide-on-workload-distribution-or-how-to-handle-heavy-splittable-tasks.409003/

[civic apex]

is it a good idea to make listeners/command handlers register themselves

?

[echo basalt]

no

as it's not explicit

[civic apex]

why?

[limpid bloom]

For more context , the world for the project is around 4gb…….. Compressed. Around 20gb on disk , not going through all of it though

[civic apex]

wdym

[echo basalt]

it somewhat breaks single-responsibility principle too

[civic apex]

how?

[echo basalt]

Classes usually stick to a few types

[dry yacht]

Tbh, I don't think that this is deal. I think the best solution lies somewhere in the middle, where you register all dependencies and all classes which need to be singleton instantiated, and the tool then figures out in which order to create them, if they require each other. That way, you still got references to their symbols and dead code elimination will be applicable, but you can just add another arg to the constructor and don't have to change up the wiring or in the worst case: even the order of instantiation.

No idea why you're against a bit of automation there.

[civic apex]

listeners do that, listen, so why not register them (something required for listening) on their own class

[echo basalt]

You have data classes, handlers, managers

Making a data class register itself to the manager starts to... do the manager's job

It's like getting hired at a company, going to HR and filing in your details yourself into the database

[civic apex]

a listener is a data class?

[echo basalt]

Not strictly

It's odd

[civic apex]

but the main class looks cleaner

[echo basalt]

not really

you're still creating objects

[civic apex]

¯_(ツ)_/¯

[civic apex]

yeah

[dry yacht]

Depends. The command handler should know what it's invoked by, so why delegate registration to the constructor caller? I usually have an interface which has a method called registerSelf(Plugin).

[civic apex]

but you dont need to see that big chunk of text saying .register a million times

[echo basalt]

instantiation order is often important

[civic apex]

which isnt important

so its distracting

[echo basalt]

you can make separate methods for those

[civic apex]

i have

[echo basalt]

It's difficult to explain grr

[civic apex]

but still

[echo basalt]

hard to explain my code style that I've developed over the past 11 years

[dry yacht]

Only because of the dependency graph. I don't care about that, the computer should solve it for me.

[civic apex]

this just doesnt look the best

[dry yacht]

It's not about looks...

[civic apex]

not about efficiency either

[echo basalt]

mans coding in the minecraft font

[echo basalt]

debatable

[chrome beacon]

Yeah make some variables

[echo basalt]

I write my code strictly focused on performance and readability

[dry yacht]

It's about how stupid it get's quickly when you actually are at a project with a decent level of complexity. Modules gonna need other modules, so you'll going to have a lot of fun when wiring everything together.

[echo basalt]

putting everything inside a black box and calling it a day isn't suitable

[civic apex]

well whatever that thing isnt that readable

[dry yacht]

Who cares about initial efficiency when the plugin is loaded up. That's sacrificing at the wrong time and place.

[sonic goblet]

No shot, are you actually coding in the Minecraft font? What an absolute mad lad

[remote swallow]

I just thought that lmao

[echo basalt]

module registry, init them all, and they can use each other

[civic apex]

thats what im saying, its not about efficiency

its the monocraft font

[echo basalt]

It is much more readable than whatever underlying code it might be running to do it

[echo basalt]

I've had plugins that took 5 minutes to start up, not fun

[civic apex]

its just one line

[dry yacht]

If the computer solved the dependency graph ahead of time and instantiated them in the right order. That means that there are no more new() calls, which then means that @civic apex would be happy looks-wise, and I would be happy work-wise.

[echo basalt]

that calls 1000 others

[civic apex]

it would call them if it was in the main class too

[dry yacht]

I bet that it wasn't because of DI. That would be so sad tho...

[echo basalt]

DI is lovely

you just need to be organized

[civic apex]

i am not

[echo basalt]

split everything into data classes, handlers or managers

[dry yacht]

You know, I get what you're saying @echo basalt. But I'm not willing to have a wiring site like this if I can solve everything automatically with a few lines of extra code. It's extremely easy, doesn't hide what's going on and saves me from having to do stupid brainless work.

[echo basalt]

It ain't brainless ¯_(ツ)_/¯

also I never have problems when it comes to wiring stuff

[dry yacht]

I can literally hire kids to write constructor calls, lol

[echo basalt]

just register a couple listeners, couple command handlers

[dry yacht]

As I've said, it only becomes an issue in projects of a certain level of complexity. Your average listener and commands won't cause that, no.

[echo basalt]

sure registering listeners is probably the most boring part, but it takes like 30 seconds at most

[dry yacht]

You're quickly at levels like these when your project is rather complex. I wouldn't want to wire 50 of those bad boys up manually, checking what I need to create first.

Look at NMS, or the client itself. They also sometimes have huge constructors. Not all software just uses a reference to a single main class, it can get quite complicated if you're trying to separate out reusable functionality.

[dry yacht]

But for literally 80% of plugin developers out there, this is enough and they shouldn't get into automatic DI for that, yes.

[echo basalt]

something tells me you're putting a lot of responsibility in a single class 🤔

[dry yacht]

It's the real world. You cannot have 200 line classes everywhere.

[echo basalt]

tell me about the real world

[dry yacht]

I literally factored out so much it's not even funny anymore. The class is doing all the basics, but somewhere you gotta join abstractions together.

[spice shoal]

touch grass

[dry yacht]

Oh yeah?

[echo basalt]

all of those commands in a single package

mfs leaking essentials sourcecode

[dry yacht]

You have to stop pulling everything apart at some level, or nothing get's done. As the symbol names of my screenshot show you, I already separated concerns pretty well. But as I've said, you have to write it up somewhere.

[dry yacht]

It's the server project I abandoned, lol.

But most of it aren't commands.

[echo basalt]

¯_(ツ)_/¯

average plugin developer dick measuring contest

[chrome beacon]

It's like the nms for mob brain behaviour

[echo basalt]

oh god the sensor system in nms is so overengineered

[chrome beacon]

Not sorted in to packages everything is a mess

[echo basalt]

they make sure to use immutablemaps everywhere

just to fuck with developers

[chrome beacon]

I'm aware guess who decided to mess with Villager AI for this Winterjam

;/

[civic apex]

i have one old plugin which only had three files, and the main class (Main.java) had 1200 lines

[dry yacht]

I'd love to see you write a hologram plugin from scratch on top of packets with persistence, commands, variable support and so on with your style of programming and then check if it's actually cleaner than mine. Not meant in a bad way at all, just curious. Because most people which tell me that my style is not clean or not conform enough mostly work on far too simple things where these patterns are easy to stick to. But it's really hard to keep it clean when you're literally trying to stick a million features together.

[civic apex]

also nesting hell

[echo basalt]

bet

packets are easy, I've done harder things

like fake blocks and fake entities that can collide with them

commands are also easy

Variable support is also easy, just a very abstract collection

Serialize that collection for persistence

And link stuff together

You now know why my class has multiple references to other modules. It's methods are dead simple, but they link features together to define higher level behavior.

I wouldn't say there should be a master origin point

just lots of modularity

So you're saying having a handler like this https://paste.md-5.net/davipohata.java is completely wrong? Having a handler which manages the local cache, writes/reads to/from persistence, looks up and creates holograms (and thus holds their dependencies) and the like?

[inland barn]

which is more preferred?

• plugin development using vscode and wsl or linux
  or
• intellij/eclipse and windows

i used to work with c++ projects via ubuntu or wsl and using visual studio code for development and was just curious about other thoughts

[spice shoal]

intellij idea for me

so , 2 * option

[river oracle]

I use Vscode on linux

but intellij on linux works as well

[inland barn]

sure, thanks!

[sterile token]

I use Ubuntu 20.04+ Intellij - They works perfect no issues

[spice shoal]

Guys i have a problem , i can't register event but idk the cause...

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

in
new ItemEvents();
new ItemManager();

[remote swallow]

You dont need the linr that just has new itemevents you already register thr listener and does item manager have listeners in

[spice shoal]

So in the game they will work the same in theory, right?

[remote swallow]

If the item events class register's listeners for item manager if it has listeners in it, yes

[spice shoal]

oh ok , thanks for information :))

[carmine urchin]

I'm trying to use NMS with mojang mappings for spigot 1.19.3 and for some reason when I write the code MinecraftServer server = craftPlayer.getHandle().getServer() in the form of a command, an internal server error occurs and the output is "Caused by: java.lang.NoSuchMethodError: 'net.minecraft.server.level.ServerPlayer org.bukkit.craftbukkit.v1_19_R2.entity.CraftPlayer.getHandle()" Are my mappings corrupted?

[sullen marlin]

you didnt remap your plugin

[carmine urchin]

I implemented the plugins specialsource-maven-plugin and maven-shade-plugin in my pom.xml, installed the remapped 1.19.3 jars, and someone gave me their pom.xml as a reference, but still the error continues. Aren't these the correct steps to remap my plugin?

[lost ferry]

hey, how to show server on craftbukkit that is in bungee list?

[remote swallow]

i would guess just like any other server type

[lost ferry]

"{server}", player.getServer().getName()))); it result "Unknown Server" on my scoreboard

[remote swallow]

oh that

[magic dome]

what would be the best way to go about setting specific heights of terrain in a world... all while keeping the vanilla cave generation underneath the height specified. IE lets say my code says that the ground should go up to y=100 in a specific xz coordinate, I know how i can set it using a custom chunk generator... but how do i ensure that vanilla generation is still occuring underneath

[remote swallow]

idk what could cause that to be unknown server

[remote swallow]

iirc theres a setCaveGen method

[lost ferry]

any solution?

[magic dome]

is this in the ChunkGenerator class?

I don't see it there

oh wait its just called "generateCaves"

it says "Shapes the Chunk caves for the given coordinates" but would that generate caves throughout multiple chunks or would each chunk be random?

[remote swallow]

no idea, i doubt many people use craftbukkit as there server jar now-a-days so it shouldnt cause too many issues

[magic dome]

ngl ive looked at chunk generators for hours and they still make little sense to me

[remote swallow]

yeah, ive got no clue how they work

i just remembered md saying something about that method

[lost ferry]

public static String getLobby(String input) {
      return ConfigFile.getConfig().getString("LOBBY-SELECTOR." + input + ".SERVER");
   }

https://ibb.co/VqGMMDB
I want it to merge with what is written in the config but i don't know the code for format {server}

[remote swallow]

what do you want {server} to be

[lost ferry]

shows the server name written in the config

[remote swallow]

if input is HUB-1 then you can just use what you already have, that would return hub-1 from the config

change .SERVER for .NAME if you want Lobby-1

Bukkit.getScheduler().runTaskTimer(JavaPluginInstance, () -> {
  for (Player player : Bukkit.getOnlinePlayers()) {
      player.doSomething();
  }
}, 0, 5);

yeah

change player.doSomething to OtherClassName.scoreboard(player)

might need new

[quaint mantle]

hey all. How do i create a boundingbox with 2 coordinates for the corners of the bounding box? I just want to figure out if im in this bounding box as well but have no clue where to start on creating the actual bounding box

created said bounding box, how do i check if enter the bounding box? Im using the player move event and im planning on having a few 100 of these regions all with checks for which bounding box i have entered, shouldnt cause lag should it?

[echo basalt]

uhh

not really

[drowsy helm]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/util/BoundingBox.html check out that

[echo basalt]

A bounding box is basically a cuboid

[drowsy helm]

so theres the constructor and BoundBox.of(location1, location2)

[echo basalt]

The thing is

[drowsy helm]

then to check if you're inside you can do .containts(position)

[echo basalt]

only thing I hate about that class

is that there's no partial contains

like

it only checks if all 4 corners are contained within one another

if you have 2 perpendicular aabb's they don't collide

[quaint mantle]

yep checked docs and did that, now the issue is, im def in the bounding box but my plugin doesnt think so

[drowsy helm]

oh interesting

print your values and see

[quaint mantle]

@EventHandler
    public void enterVanguardRegion(PlayerMoveEvent e) {
        Player player = e.getPlayer();
        Location loc = player.getLocation();
        BoundingBox vanguardBox = new BoundingBox(133.0, 71.0, 300.0, 139.0, 71.0, 307.0);
        if(vanguardBox.contains(loc.getX(), loc.getY(), loc.getZ())) {
            player.sendMessage("Entered Box.");
        } else {
            player.sendMessage("Not in Box???");
        }

    }```

yeah good idea

[drowsy helm]

also no bounding boxes don't cause heaps of lag

depends how often you are checking

[echo basalt]

oh yeah btw buoo

[drowsy helm]

its just a greater than lesser than check

yur

[echo basalt]

the guy from the rpg server keeps begging me to help him out

[drowsy helm]

lol

ill tell him to stop

[echo basalt]

like

paid work is one thing

but he's probably more broke than me

[quaint mantle]

136.30718410893195 71.0 302.34903518358374 My coords

why am i not in the bounding box

im lost

[quaint mantle]

also on this, its being checked every time someone moves which i imagine is going to cause lag with a lot of people online, is it still safe or time to switch methods?

if anyone has any idea on why this bounding box isnt working, please lmk

[quaint mantle]

Use papi and async bukkit task

Less lag

[echo basalt]

wut??

making things async just because isn't... ideal

also papi has nothing to do with boundingboxes

[quaint mantle]

both things you said make no sense to me!

[echo basalt]

making stuff async just because is something I do... more than I should

[quaint mantle]

but ill deal with that when i figure out why this bounding box isnt working

[echo basalt]

because I like to play it safe :)

[quaint mantle]

so i should make it async?

[echo basalt]

no

[quaint mantle]

okay gotcha

do you see anything wrong with what im doing?

bc it reallyyyyyyyy doesnt want to work

[echo basalt]

I mean..

the Y level is always the same

that can cause issues

try like

going in the area, in-game

but 1 block below

[quaint mantle]

okay

nope no changes

[echo basalt]

or above idk how you're doin this

actually I see hm

[quaint mantle]

above & below show no changes

oo

[echo basalt]

make the Y like 3 blocks tall

having it as the same value is.. .not ideal

at least set it to like 1 block above

you're making a bounding box that's like a sheet of paper

instead of a box

[quaint mantle]

that is a good point

ill change it to bedrock to height level

ah yep

look at that

it fixed!

whats the best way for me to make a getPlugin method?

i dont want to run into issues getting an instance of my main class later down the road

[jagged monolith]

Use the current getPlugin method?

[jagged monolith]

If it's for the same plugin, use Dependency Injection

[rare rover]

how do i write to a packet? Using mojang mappings?

[sonic goblet]

I'm very bad at math and I'm having a bit of brain lag.
I'm trying to create a chest populator that uses a scale of 1-10 to determine how full the chest(s) should be. 1 being empty or nearly empty and 10 being full or nearly full. But I'm having some problems translating that into code. My two variables are the container size, and the "purity" of the chest (being on the 1-10 scale)

Any math chads have any suggestions of how I should go about that?

[jagged monolith]

?paste

[undone axle]

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

[drowsy helm]

LoginEvent doesnt have a .getPlayer method iirc

[rare rover]

anyone?

[drowsy helm]

PostLoginEvent

[drowsy helm]

all the necessary components you need are in the constructor

https://nms.screamingsandals.org/1.19/

for the event

[jagged monolith]

Yeah, Use the PostLoginEvent instead of the LoginEvent

[remote swallow]

^^

[jagged monolith]

PostLoginEvent has a getPlayer()

[drowsy helm]

did you copy paste all that code from somewhere?

the LoginEvent

has to be PostLoginEvent

[jagged monolith]

1. Remove LoginEvent
2. Use PostLoginEvent
3. Get the proxied player from the event

[quaint mantle]

Hey, anyone here know how to make text pop up on your screen? Sort of how theres text right in the middle of your screen

[drowsy helm]

yeah sendTitle

[jagged monolith]

You'd need to create an actionbar. Or Title/subtitle type thing

[remote swallow]

Player#sendTitle

[quaint mantle]

okay so send title it is

[drowsy helm]

https://helpch.at/docs/1.15.2/org/bukkit/entity/Player.html#sendTitle-java.lang.String-java.lang.String-\

[quaint mantle]

i see what you were trying to tell me, its the one above the hotbar right?

[drowsy helm]

idk why helpchat was the first that popped up

[remote swallow]

Use string string int int int

Other one is deprecated

[quaint mantle]

okay and what if i just dont want a subtitle

do i just do ""

[remote swallow]

Pretty much

[quaint mantle]

perf

and are the ints as ticks?

[jagged monolith]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#sendTitle(java.lang.String,java.lang.String,int,int,int)

[remote swallow]

Think so

[drowsy helm]

yeah

you can do null

instead of ""

looks a bit nicer

[jagged monolith]

Parameters:
title - Title text
subtitle - Subtitle text
fadeIn - time in ticks for titles to fade in. Defaults to 10.
stay - time in ticks for titles to stay. Defaults to 70.
fadeOut - time in ticks for titles to fade out. Defaults to 20.

[quaint mantle]

oh i was looking at the helpchat one

thanks

[drowsy helm]

yeah my fault

[quaint mantle]

allg

what in the world is helpchat anyways lol

[jagged monolith]

An many other things

[quaint mantle]

oh thats neat

Hellow, what is the best plugin for tab?

[remote swallow]

Placeholder api is more known imo

[remote swallow]

TAB

[drowsy helm]

lol what

[jagged monolith]

https://github.com/NEZNAMY/TAB

[quaint mantle]

oh shit

so uh

[chrome coyote]

a premium tab?

with more options

[remote swallow]

The link omega weapon dev sent

Its very customisable

[jagged monolith]

It's free. You only need to pay if you want support from the dev which isn't really needed.

[quaint mantle]

since its whenever im moving, that title keeps coming up, 1s lemme send my code:

// PDC :
        Player player = e.getPlayer();
        PersistentDataContainer playerPdc = player.getPersistentDataContainer();
        String playerLocation = playerPdc.get(new NamespacedKey(Nebula.getPlugin(), "playerregion"), PersistentDataType.STRING);


        Location loc = player.getLocation();
        BoundingBox vanguardBox = new BoundingBox(133.0, 0, 300.0, 139.0, 256, 307.0);
        if(vanguardBox.contains(loc.getX(), loc.getY(), loc.getZ())) {
            if(!playerLocation.equals("vanguard"))
                player.sendMessage("Entered City: Vanguard.");
                playerPdc.set(new NamespacedKey(Nebula.getPlugin(), "playerregion"), PersistentDataType.STRING, "vanguard");
                player.sendTitle("Entered Vanguard", "", 10, 70, 20);
        } else {
            player.sendMessage("Not in Box???");
            playerPdc.set(new NamespacedKey(Nebula.getPlugin(), "playerregion"), PersistentDataType.STRING, "unknown");
            System.out.println(loc.getX() + " " + loc.getY() + " " + loc.getZ());
        }```

[rare rover]

oh, okay

[quaint mantle]

the chat msg only sends once, the title keeps coming up repeatedly

[drowsy helm]

ill send this gain https://nms.screamingsandals.org/1.19/

its super useful

[quaint mantle]

im assuming its bc it never finished its sequence

no idea how to deal with that tho

[drowsy helm]

you sending region entered messages?

you have to keep track of whether a player has entered before

orelse it will spam

[quaint mantle]

yep i did

the chat msg sends once

title sends a million times

[rare rover]

okay

1 more question

[drowsy helm]

oh

skill issue tbh

[quaint mantle]

i have an idea to fix it

fax yo

[rare rover]

how would i send a packet to the server, never sent one to the server

only to a player

[drowsy helm]

like a spoof packet?

[rare rover]

sure

[drowsy helm]

uuuh fuck

i dont actually know if thats possible

you would have to have a fake client

[rare rover]

im just trying to teleport the entity using a packet

so i can use async

[quaint mantle]

why use a packet?

oh

[drowsy helm]

thats not a good idea

its gonna cause heaps of desync

and technically the player wont be teleported

just teleport them on the main thread

use a runnable or smth

[quaint mantle]

fuck my idea failed

[rare rover]

alrighty

so just use stand.teleport(location);?

[drowsy helm]

yeah

[rare rover]

okay

[quaint mantle]

yeah uh buo

[drowsy helm]

unless you are using the packet to fake something being in a location

[quaint mantle]

how do i just send that title once

i have 0 idea

[drowsy helm]

when you say it pops upmultiple times

does it not go away

or just fades in and out

[quaint mantle]

oh no, everytime i move, it resets its sequence

it constantly fades in

[drowsy helm]

but the chat message only once right

[quaint mantle]

yep

[drowsy helm]

oh

you didnt do brackets

[quaint mantle]

brackets where?

[drowsy helm]

if(vanguardBox.contains(loc.getX(), loc.getY(), loc.getZ())) {
            if(!playerLocation.equals("vanguard"))
                player.sendMessage("Entered City: Vanguard.");
                playerPdc.set(new NamespacedKey(Nebula.getPlugin(), "playerregion"), PersistentDataType.STRING, "vanguard");
                player.sendTitle("Entered Vanguard", "", 10, 70, 20);
        } else {

vs

if(vanguardBox.contains(loc.getX(), loc.getY(), loc.getZ())) {
            if(!playerLocation.equals("vanguard")){
                player.sendMessage("Entered City: Vanguard.");
                playerPdc.set(new NamespacedKey(Nebula.getPlugin(), "playerregion"), PersistentDataType.STRING, "vanguard");
                player.sendTitle("Entered Vanguard", "", 10, 70, 20);
            }
        } else {

for the playerLocation.equals if statement

[quaint mantle]

oh for fucks sake

cmon bro

[drowsy helm]

wheres the CreaShield class?

if you are trying to load your main class it should be dashspy.main.Main

[stray nacelle]

lol

[quaint mantle]

is there any way for me to not be forced to restart my server without risking my plugin having a mental breakdown?

it is so slow

[remote swallow]

Your package would be dashspy.main not dashspy.main.Main

[stray nacelle]

i think plugman

but i use plugwoman cuz it faster

[jagged monolith]

[remote swallow]

Depends what it does, plugman, plugwoman are all options but then you could use /reload confirm although its not recommended

[quaint mantle]

women 🍵

[stray nacelle]

no

[stray nacelle]

https://www.spigotmc.org/resources/plugwoman.82302/

[jagged monolith]

You should learn the basics of java before coding a plugin

[drowsy helm]

Plugman in some situations

Most cases it’s best to just restart

[quaint mantle]

well, what would cause issues if i used plug whatever

[drowsy helm]

You can optimise your server to start in less than 10 seconds

[quaint mantle]

ooh please help me there

what can i do for that

[remote swallow]

Theres a load that could arise

[quaint mantle]

shit takes a solid 40-1m to load

[jagged monolith]

Using plugin management plugins or /reload aren't really a good idea. Unless a plugin has it's own in-built reload command, you should restart the server.

[drowsy helm]

Test environment use as little ugins as possible

[stray nacelle]

my shit takes 0.5m to load

[remote swallow]

So there isnt really a good way to tell if it would work or not

[stray nacelle]

cuz no code

[quaint mantle]

thats fair

its gonna be fairly big by the time im done

so server load times are an issue

[remote swallow]

Best bet you have is using a plugin manager and hoping it doesnt break anything or hoping /reload doesnt then

[remote swallow]

Huh

[quaint mantle]

i asked this yesterday but didnt get the answer i was looking for, how do i make a gun that functions like one from actual triple A games. The gun shoots as long as I hold the left click button down and when my finger goes off the left click button, it stops shooting

[jagged monolith]

Maybe use the PlayerInteractEvent, check if the block was air and the hand was the main hand. Then do the gun mechanics

You'd probably need to mess with particles, vectors and locations

It would be somewhat possible, but would take a bit and lots of trial and error.

[quaint mantle]

see but then it would only fire the event once so id only shoot once

im trying to figure out how to keep the gun shooting while im still holding left click down

[remote swallow]

Wouldnt the event fire consecutively if you were holding

[quaint mantle]

nope it wouldnt, i tried

[jagged monolith]

No, I think it only fires once.

[quaint mantle]

it only fires nce

[jagged monolith]

I've just had a quick look at the docs and I honestly don't think it's possible without delving into packets.

[quaint mantle]

thats fine with me, whatever to get it done

[jagged monolith]

Because there really isn't a way to check if a player is holding the mouse button

[quaint mantle]

ive been meaning to learn nms, this would force me to

what packet would the player even be sending to inform me that their holding the mouse down

[jagged monolith]

Unless someone else knows of a way to do it, I think packets might be the best option. (not 100% sure if possible with packets but should be)

[quaint mantle]

now that i think abt it, every server with gun mechanics always use right click to shoot, i havent tested it but does right click always fire if held down?

[icy beacon]

so I updated my plugin and now it's ~4.7MB, but the max size for uploading files is 4MB, so where do I upload the file now? is there a traditional hosting for this maybe?

[maiden thicket]

do u mean https://github.com/atlasmediagroup/scissors

kidding

[jagged monolith]

^ Didn't know that was a thing. Wouldn't trust it

[icy beacon]

nvm imma use releases

[maiden thicket]

my friends made it

it is trustworthy

xD

it was custom made fork of paper to patch creative mode exploits

primarily for the free op server they run

[remote swallow]

did you minimize it

[jagged monolith]

Using a shadowJar or anything for compression? Surely there is a way you could bring that size down. Maybe some of the dependencies could be set to compile instead of implemented

[remote swallow]

iirc maven shade has a minimize tag so some size would able to come off

[torn shuttle]

hm if class 1 implements cancellable and class 2 extends class 1 if I want class 2 to still implement cancellable the same as class 1 do I need to tell it to implement cancellable again or would it know to do that through polymorphism?

it should be extended right?

[cobalt thorn]

Hi, im trying to make a translator for chat, im using Protocollib i manage to make the packet works, but i don't know how to change the message to the new one and resend it to the user

code:

public class Message extends PacketAdapter {

    public Message(Translator plugin) {
        super(plugin, ListenerPriority.NORMAL, PacketType.Play.Client.CHAT);
    }


    @SuppressWarnings("deprecation")
    @Override
    public void onPacketSending(PacketEvent event) {
        if (event.isCancelled()) {
            return;
        }

        PacketContainer packet = event.getPacket();
        String message = packet.getStrings().read(0);

        String translated = Translate("de", message)
    }
}

[hazy parrot]

Class 2 will still impl that interface, you can always override implementation

[torn shuttle]

that's what I assumed, thanks

[hazy parrot]

Why would you use packets for this?

[cobalt thorn]

because i can change text from plugins too and its individual for each player

[remote swallow]

you could still do that on event priority highest

for chat messages

[cobalt thorn]

for plugins too?

oh

i need it more for plugins

[remote swallow]

customising messages another plugin sends i would guess needs packets to intercept

[cobalt thorn]

for chat i have already the solution but for plugins im trying to search the way

[cobalt thorn]

and im already doing that with Protocolib

[charred pollen]

how does a baltop gets created, been wondered for awhile, and my plugin needs this command 🥹

[remote swallow]

best bet i can say is check the event method and see what methods it has

[hazy parrot]

Isn't there write method, same way you get read?

[jagged monolith]

It gets created by a plugin creating it.

[hazy parrot]

Also make sure it's chat packet

[remote swallow]

getCommand("command").setExecutor(new ClassName())?

[jagged monolith]

It depends how you want to create it.

[hazy parrot]

If you are storing balance in some kind of database, it's just one query

[charred pollen]

got balance stored on PlayerConfig

[rough drift]

@quaint mantle @dry yacht What about TabPosition.ofSlot(2) and TabPosition.ofPos(0, 1);

y/n?

[jagged monolith]

It depends how you want to create it, If in chat, Then just do a simple string list to print out the baltop

Use a for loop to loop through the balances, and add it to a list then print the list

[charred pollen]

tried to use sort, is that how you create it, then i can just go back to it till i find a way

[hazy parrot]

It's probably better to use correct database for this stuff instead of storing in yaml

[jagged monolith]

You'll need to get an array or list of the balances, then print that list to the player.

[charred pollen]

its stored in data.db

[hazy parrot]

It's sqlite?

Because it looks exactly like yaml config

If its sqlite, just select player, balance from table order by balance desc limit 15 for example

[torn shuttle]

my programming playlists keep getting weirder

[jagged monolith]

Same concept. You'd need to get a way to Loop through the balances, and add them to a list, with the players name, position and balance and send it to the player

[charred pollen]

on the File configFile = new()
i set it as data.db, but how i setup players is bad?

[jagged monolith]

Maybe get the balances, put them into an array, sort the array based on the values, then just loop over the array

[hazy parrot]

Because extension doesn't matter, it's still yaml config, which is in pratcice not used for data storage

[remote swallow]

do you not use a java database api for data.db

i would recommend using hikari cp and sqlite

with a connection pool

[jagged monolith]

HikariCP is really good. I just always get confused trying to implement it, I have always wanted to. Just never actual spent the time to learn it

[remote swallow]

ive got no clue how it works either lol

one of my friends plugins used it so i just copied the concept

it works as intended so i just use it if i need sqlite

[quaint mantle]

How to get value from async task?

[charred pollen]

thanks, will try 😄

[remote swallow]

async task as in

[jagged monolith]

I've had multiple attempts at adding it and gave up each time haha

[remote swallow]

Hey, I get a weird error when I run my server, it seems to be something at TabExecutor. Am I doing something wrong?

The error in question

getCommand("chud").setExecutor(new CoordinatesHUDTabExecutor());
getCommand("chud").setTabCompleter(new CoordinatesHUDTabExecutor());

[remote swallow]

is it in plugin.yml

[jagged monolith]
