    public void onChatEvent(AsyncPlayerChatEvent e) {
        if(e.isCancelled()) return;```
Why does this not work? e.isCancelled is always false

[eternal oxide]

If you are you are probably going to have to do it with a child first class loader

[dry yacht]

Priority, probably

[warm mesa]

Somebody know why I got this error?

[distant ridge]

I've set this as both the highest and lowest and it didn't make a difference

[dry yacht]

Wouldn't relocate like that tbh, using shaded as a parent package is not the intended idea. It should be your root package. You also dropped a package (code, I think) on a relocation.

[distant ridge]

The event is being cancelled by another plugin completely.

[quaint mantle]

Could you show me what you mean?

[thorn crypt]

So, I'm trying to use that and import all needed stuff but their is some things that don't wanna be imported

[dry yacht]

Oh, maybe set ignoreCancelled on the annotation?

[distant ridge]

Ah that's a good idea

[quaint mantle]

[lost matrix]

This is written for ProtocolLib 5.0.0 and Spigot 1.19.3

[thorn crypt]

I'm using Spigot 1.19.3, but to be honest I didn't knew ProtocolLib 5.0.0 was out, I thought 4.8.0 was the last

[lost matrix]

4.8.0 doesnt even work for 1.19

[thorn crypt]

Oh, first time trying to use it in this version sorry 😅

[eternal oxide]

ok shade all your dependencies and don;t relocate. You shoudl be treating yoru classLoading as a child

[dry yacht]

shaded should be your root-package. Like country-code.your-nick.your-plugin-name. This is the only "guaranteed" way that you won't have namespace collisions and mess your versions up again. com.google.code.gson also became com.google.gson in your relocation. If you relocate, the corresponding imports/FQNs will be patched too, so there's no need to shorten anything and thus maybe make it misleading.

[eternal oxide]

^ you could

[quaint mantle]

Which one is better to do?

[dry yacht]

Oh, we're talking about custom classloaders here, xDD

[quaint mantle]

Still getting the error

[thorn crypt]

Is there a different way to use 5.0.0 ? Cuz I tried replacing 4.8.0 by 5.0.0 but it don't want to

[dry yacht]

Is this the error we're talking about?

[quaint mantle]

This

[warm mesa]

How Can I use NMS in my plugin?

[lost matrix]

        <dependency>
            <groupId>com.comphenix.protocol</groupId>
            <artifactId>ProtocolLib</artifactId>
            <version>5.0.0-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>

[thorn crypt]

Oooh snapshot, sorry. Where do you find these information, I couldn't find them myself

PS : I still get an error with ```java
TaskManager.scheduleSyncDelayedTask(() -> {

it wont let me import a thing

[dry yacht]

Did you set the plugin class loader as your class loader's parent? I think you tried to operate between two separately loaded GSON classes. They may have the same FQN, but are in different "modules", or what it's called. Don't quote me on that, but it would be the easiest to try.

[quaint mantle]

no

[dry yacht]

Yeah, after thinking about your stacktrace some more... It just looks like a version mismatch indeed, xD

[lost matrix]

Read the comment above this line

[quaint mantle]

So how would I fix that then?

[dry yacht]

You don't access your relocated Gson, the FQNs in the stacktrace all start with com.google.gson. You relocate com.google.code.gson.

[thorn crypt]

It work perfectly, I don't know what to say, just thank you 😭
And sorry for all stupid question I could ask really !!

[quaint mantle]

That's what im what dependency is though com.google.code.gson

Omg that fixed

There is no way

[dry yacht]

Is that error you posted occurring when you try to load something through your classloader?

[dry yacht]

What was it?

[quaint mantle]

Changing it to com.google.gson for relocation

[quaint mantle]

yes

[dry yacht]

How the hell did that solve it

[quaint mantle]

Now another error is occurring though

[dry yacht]

The class you're trying to load shouldn't have these relocations applied

So it should trip up there

[dry yacht]

Now I'm really curious, mind posting that? xD

[quaint mantle]

https://paste.md-5.net/aqidatafic.pl Now im using 1.8 just because I had a server already made but again this is not a plugin

[dry yacht]

Btw, what is it then? Your own plugin loader? xD

Wow, that error is cursed

[quaint mantle]

What is what?

[dry yacht]

What are you trying to develop?

That would help

[quaint mantle]

I'm just trying to gather data from a jar

Interesting the error does not occur when you use 1.18 but 1.8 it does

[dry yacht]

Trying to load a server jar? I just really don't get why there are nms/cb packages when it's not a plugin, xD.

[quaint mantle]

Because I originally had made it into a plugin then decided not too

[eternal oxide]

are you trying to modify at runtime, like mixins?

[quaint mantle]

Now its not suppose to function as a plugin though

[dry yacht]

SafeConstructor extends BaseConstructor, means that Type 'org/yaml/snakeyaml/constructor/SafeConstructor' (current frame, stack[3]) is not assignable to 'org/yaml/snakeyaml/constructor/BaseConstructor' doesn't make sense to me...

[quaint mantle]

Not modifying anything

[quaint mantle]

🤷‍♂️

[dry yacht]

You add snakeyaml as a dependency to your project, so I guess 1.8 expected another version, and you just load the one you (seem to ) shade, instead of the one the jar itself contains

[quaint mantle]

Yea

[dry yacht]

Try relocating your snakeyaml too, so the class loader is not using yours

[vocal cloud]

1.8 moment strikes again

[quaint mantle]

Yea that worked

[dry yacht]

If I'd only get a penny every time somebody complained

[dry yacht]

Any other exception appeared? xDD

[quaint mantle]

Nevermind I lied

Same thing still

[dry yacht]

Can you send the pom again?

[quaint mantle]

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

[dry yacht]

...

That relocation is basically a noop, xDD

Try <shadedPattern>shaded.org.yaml</shadedPattern>

[analog thicket]

How would i make this animation faster?

        new BukkitRunnable() {

            int i = 0;
            int x = -360;

            public void run() {
                i++;
                if (i < 100) {
                    armorStandLoc.add(0, 0.025, 0);
                } else {
                    stand.setHeadPose(new EulerAngle(0, Math.toRadians(x) , 0));
                    x++;
                }
                stand.teleport(armorStandLoc);
                if (i >= 200) {
                    cancel();
                    stand.remove();
                    openCrate.resetOpenStatus(player);
                    new crateRewards(player);
                }
            }
        }.runTaskTimer(Casino.getInstance(), 0, 1L);
    }

[granite burrow]

How can I display a item in chat using the hover event. I can get a hover message made however I cannot get an itemstack to be turned into a base component array

[dry yacht]

Either increase your step size or - if you need to go faster than the tick rate - you need to go into your own thread.

[analog thicket]

Arh okay thanks

[dry yacht]

Just make sure you're not going to block the server from shutting down, xDD.

[quaint mantle]

RIGHT

I frogot about that

[analog thicket]

Yeeeah maybe ill just increase the step size haha

[dry yacht]

Or rather make sure that the thread dies if the plugin unloads. Something like

new Thread(() -> {
  while (this.running) {
    Thread.sleep(x);
  }
}).start()

And then set running of your instance to false when the plugin is being disabled.

[quaint mantle]

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

A new one now

[analog thicket]

Yeah i could do that, but its probally better to increase step size relative to server performance

[dry yacht]

Really depends on what you're trying to do. If you want to play animations above 20 fps, you need to take that route. If just increasing the "delta" per step is enough to solve your problem, that's fine too.

[dry yacht]

Tbh, without understanding what you're doing and how you do it, that one is a bit too far out for me now, xDD.

[analog thicket]

Yeah, it should do, I don't need high fps animations.

[torn shuttle]

"oh yeah I'll just tweak a quick thing for a release before bed"

that was nearly 6 hours ago

this is a nightmare

[echo basalt]

imagine having code that's so messy that it takes 6 hours to tweak something real quick

[torn shuttle]

tbf I'm dead sure the inventory#remove(itemstack) method is just not working here

[echo basalt]

nah

[torn shuttle]

the item isn't null, I can see that it is identifying it correctly

it's just not removing it

[echo basalt]

well

[lost matrix]

Unmatched nbt data probably

[echo basalt]

Inventory#remove is a bit picky with amounts

[torn shuttle]

it's just a sword

[echo basalt]

it does equality checks

[subtle folio]

Is there a way to create fake players with the new game profiles?

[echo basalt]

durability maybe?

[torn shuttle]

and I didn't modify it in any way, that is sort of the point

no durability change either

[lost matrix]

Only when using ProtocolLib or NMS

[torn shuttle]

I don't really know how to fix this one ngl

[echo basalt]

make your own remove method

[lost matrix]

Yeah just iterate the inv and check every slot with isSimilar ^^

Unless you want to keep track of the amount

[echo basalt]

or do your own checks if you're hypixel

[torn shuttle]

I might have to do my own checks

[echo basalt]

mfs out there associate an NBT ID and compare the ID instead of comparing meta

[torn shuttle]

I need to test something, it's just a pain because there's seemingly no unified array for all inventory contents

[echo basalt]

they have like a global palette of some sorts

it's wild

[quaint mantle]

Was just a world gen problem xD

[echo basalt]

but apparently makes checks like 5x faster

[torn shuttle]

I have this really weird suspicion

because it's on the same tick I'm teleporting players

across worlds

and I just have this nagging suspicion it's a minecraft bug

[echo basalt]

nobody:

hypixel:

One of the things we changed within Spigot, was ItemStack and ItemMeta comparisons and accessing. Spigot was comparing NBT Data in a way that was not efficient, and with the sudden rise in SkyBlock popularity, all those items you see in chests, inventories, etc were constantly being compared against each other, especially by things like hoppers, etc, so what did we do to fix it? We added an ID to the NBT compound, then when we first compare items, if they are equal we sync up their IDs and we know for certain that they’re the same, we also track the parent of each NBT Tag, so when something changes within it we change the ID and thus the process begins again, this makes it much faster for us to do just as many comparisons.

[torn shuttle]

I mean seems like it makes sense

[dry yacht]

Comparison cache, what's wrong with that? xD

[echo basalt]

It's probably just a hashcode

[torn shuttle]

what in the fuck did I just see

I swear something's wrong I can feel it

this is further compounded by this not being consistent

god this is such a stupidly overkill feature too

I'd regret ever making it if it wasn't so fun

ooh

did I flip current and upgraded

ok it looks like somehow I did

argh I know what happened

I forgot that the upgraded itemstack was using a shallow copy of the original

aight now it's good

[echo basalt]

bro mfs at work didn't push

I hate my life

[torn shuttle]

speaking of pushing, I'm up to 350kg on my leg press now

the path to 400 is real

[echo basalt]

pretty sure I was pushing that when I was 15

[torn shuttle]

how much are you pushing today

[echo basalt]

idfk I've not really been hitting legs nowadays

or the gym at all honestly

[torn shuttle]

so basically what you're saying is you don't even lift bro

[echo basalt]

I go there once in a while, do the same chest & triceps workout and fuck off

[torn shuttle]

one step closer to yeeting you off a cliff

[echo basalt]

the difference between me n u is that I can write good code and you flex about pushing light

[torn shuttle]

I am pretty sure the real difference is that only one of us is dodging taxes

[echo basalt]

I saw a guy that looks exactly like you, today

dont remember where tho

[torn shuttle]

impossible, no one can look this good

[echo basalt]

how much is the circus paying you

[torn shuttle]

they couldn't place an offer on my position as a strongman, seems like you really destroyed their budget with your clowning around

well I think I see the immediate issue here, players are out of an instance before it's time to loot

[echo basalt]

we both know those are styrofoam weights

[torn shuttle]

that's why they didn't have the budget, do you even know how much 1 ton Styrofoam plates cost?

not to mention it would barely fit in the country, part of the gun show would be happening in spain

[echo basalt]

ant iq

[torn shuttle]

don't be so down on yourself, I'd say you can reach portuguese room temp in these winter days

[echo basalt]

you forgot I live in the south

[torn shuttle]

ah yeah a nice hot 24c

very clever of you to observe that

[echo basalt]

convert it to fahrenheit and it equals your height in cm

[torn shuttle]

aren't you shorter than me?

[echo basalt]

nope

[torn shuttle]

how tall are you

[echo basalt]

188

[torn shuttle]

ok so basically the same height

185

[echo basalt]

if you think 3cm is nothing then I feel sorry for your wife

[torn shuttle]

go take your schizophrenia meds again, you are seeing things

[echo basalt]

oh yeah I forgot your wife doesn't exist

[worldly ingot]

I'm his wife

This is #help-development by the way

[echo basalt]

we know

[torn shuttle]

yeah I'm helping illusion develop some character

[worldly ingot]

So why are you still here talking about wives? lol

Go to #general or just stop talking

Either is fine

[echo basalt]

according to your pfp, is magma the one on the left?

[torn shuttle]

that's why I love you wife

always so sassy

[torn shuttle]

man go clone yourself a couple of times so you can collectively have a few braincells to rub together, (s)he said (s)he was my wife

[echo basalt]

aight ladiesman

[torn shuttle]

well now I need to delay the dungeon ending by a bit

[wet breach]

not sure if that would work, could try it but might have to specify in code where its at

from what I gather it expects it to be in your root jar directory

well the root of your project

[ancient jackal]

Just noticing I've never put permissions into the plugin.yml but always checked for them in commands... I recall testing before I knew about this and everything was working but how bad could it end up

How do I use dependencies in my plugin? I'm trying to use snakeyaml

[rare rover]

In your pom.xml or gradle.build

[fervent panther]

Why is this a problem?

[lost matrix]

Because you didnt specify a variable with the name "ork.snakeyaml.version", did you

[quaint mantle]

yea what that guy said

[fervent panther]

oh lol where would I do that

ok thanks

[quaint mantle]

Just put a version number in there

[fervent panther]

I just changed it to a number

[worldly ingot]

Converting to what?

[quaint mantle]

hex 2 hex

[rare rover]

Just to chatcolor format

[lost matrix]

Usually you would do something like this:

  <properties>
    <java.version>17</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <org.snakeyaml.version>1.33</org.snakeyaml.version>
  </properties>

[rare rover]

Since its &x&1 ect

[fervent panther]

ah I see thanks!

[quaint mantle]

It's interesting to see people program in vscode

[rare rover]

I used to have a good method for converting but i dont anymore

[buoyant viper]

i made 1 recently idk

// Converts &#RRGGBB to &x&R&R&G&G&B&B
    private static String toSpigotHex(String text) {
        StringBuilder sb = new StringBuilder();

        for (var i = 0; i < text.length(); i++) {
            var c = text.charAt(i);

            if ((c == '\u00A7' || c == '&') && i + 7 < text.length() && text.charAt(i + 1) == '#') {
                var hex = text.substring(i + 2, i + 8);

                if (hex.matches("[a-fA-F0-9]{6}")) {
                    sb.append("\u00A7x");
                    for (int o = 0; o < hex.length(); o++) {
                        sb.append('\u00A7').append(hex.charAt(o));
                    }

                    i += 7;
                    continue;
                }
            }

            sb.append(c);
        }

        return sb.toString();
    }```

[worldly ingot]

+1 for using a StringBuilder

-1 for not precompiling your RegEx patterns

[buoyant viper]

whats the -1

oh

so funny thing

i did try doing that w Pattern and Matcher stuff

[quaint mantle]

public final Pattern HEX_PATTERN = Pattern.compile("&(#[A-Fa-f0-9]{6})"); happy birthday

[buoyant viper]

but it ultimately just shit on me bc i was too stupid

but yeah ig i couldve just not tried to overcomplicate it and just used Pattern#matches or w/e

[worldly ingot]

I mean all you really have to do is pattern.matcher(string).matches()

[buoyant viper]

yeah the thing is i was trying to use the result of the Matcher

[worldly ingot]

Matchers aren't necessarily cheap but it's better than recompiling the regex is all

[buoyant viper]

and it was not having it

    private static String translateHexFormat(String text) {
        StringBuilder sb = new StringBuilder();
        Matcher matcher = HEX_PATTERN.matcher(text);

        while (matcher.find()) {
            if (matcher.start() > 0) {
                sb.append(text, 0, matcher.start() - 1);
            }

            sb.append("\u00A7x");
            for (int i = matcher.start() + 2; i < matcher.end(); i++) {
                sb.append('\u00A7').append(text.charAt(i));
            }

            text = text.substring(matcher.end());
        }

        sb.append(text);
        return sb.toString();
    }``` this is what it was originally, it *almost* worked, but fell apart real fast

[rare rover]

hmm

[buoyant viper]

it took me days to realize my issue was i was modifying the original text string without updating Matcher

so i shouldve gone for an approach that either didnt reassign text or update matcher on each iteration (gross)

[buoyant viper]

ive had intellij yell at me enough times for concatenating in a loop that its drilled into my head to use StringBuilder

[worldly ingot]

Good. As it should

[frank kettle]

Why does it require StringBuilder?

I see intelliJ warn me about it all the time. What's the con about using strings?

[worldly ingot]

String concatenation in a loop isn't very memory efficient so if you can use a string builder you should

[frank kettle]

How bad is it?

Cause I do it all the time

But my strings in fors are usually small fors, not huge or "infinite" loops

[worldly ingot]

Very, very old answer (and tbh the JVM has probably gotten better since then), but this is generally the reason
https://www.reddit.com/r/java/comments/nk7ch/comment/c39r41h/?utm_source=share&utm_medium=web2x&context=3

[frank kettle]

Oh I see

So in small loops like fors of 5-10 shouldn't be too big of a issue, just a good practice to start doing

I didn't know it was an issue, sometimes intellij gives warnings for code efficiency that isn't properly a problem.

I'll start using StringBuilder from now on, thank you

[wet breach]

the issue is more or less the JIT being unable to optimize that code better

if it was in a loop

especially nested loops

nested loops do not always get unwound, therefore other code bits may not get optimized as well because of it

Don't need mods.

Unless it's for 1.8

Resource packs should be able to do it

no, you would have to implement your own hitbox

which won't be easy

[hushed pawn]

what is the topical method to create and manage minigame arenas?

[ancient jackal]

Best way people manage commands without making a big mess out of the OnCommand method?

make a single class for it

Yes please do

getCommand setExeuctor API

[ancient jackal]

That is pretty cool, never thought of it that way

[ancient jackal]

Don't you have to do this to register commands anyways

[wet breach]

I didn't want to spend time adding a bunch of commands to plugin.yml

so all those commands are technically subcommands

[icy sage]

yeah but instead of making your plugin class the executor you use different classes

[ancient jackal]

But tab completion 😢

[wet breach]

I never cared for it and this plugin was made before that

but even if it wasn't I still wouldn't care about it

[ancient jackal]

Yeah I have my TabExecutor class for a single command that is 70 lines long and has a lot of boilerplate checks

[wet breach]

since I typically keep my commands pretty easy to use and remember, as well as documented on the resources page I don't care about those that rely on tab completion

[ancient jackal]

I would rather refactor it to make it easy to add any arguments to any sort of command than rewrite some things 10 more times

[ancient jackal]

That's fair

[wet breach]

https://www.spigotmc.org/resources/servertutorial.28804/

although server tutorial needs to be updated to work again which I will do at some point lol

you could make a base command class that implements CommandExecutor with utility methods for that

[mortal hare]

probably you can by altering server's logger instance

but i dont know how that would work

maybe there's already configuration key for that in one of the server's YAML files?

[desert tinsel]

how can I differentiate the inventory from the top one from the bottom one?

[chrome beacon]

Top and bottom inventories from the view

[desert tinsel]

ok, but how can I cancel clicks only on top inventory?

[chrome beacon]

Get the inventory from the click

And check if it's the top one

[desert tinsel]

ok, thanks

                Inventory inventory = e.getInventory();
                if (inventory.equals(e.getView().getTopInventory())){
                    e.setCancelled(true);
                }```
This doesnt work, somehow

[icy beacon]

tbh working with raw bukkit inventory api is pain

just use a library

i prefer TriumphGUI but check others too to see which one fits your needs

[desert tinsel]

I just need to cancel clicks for the top inventory

[icy beacon]

what event are you listening to?

[desert tinsel]

InventoryClickEvent

[chrome beacon]

Don't forget the DragEvent

[icy beacon]

shouldn't InventoryInteractEvent cover them all

[quiet ice]

you cannot listen to it iirc

[icy beacon]

why not?

[quiet ice]

or there is some other catch, but I recall not being able to use it

[quiet ice]

it being abstract and not having the HANDLER field

[chrome beacon]

^^

[icy beacon]

ah

[mortal hare]

Working with native bukkit command api is more painful

[chrome beacon]

Working with the DFU is more painful

[icy beacon]

im getting this errror:

and i cant find anything on how to fix it.
this is my pom.xml
https://paste.md-5.net/axatutuvis.xml

[kind hatch]

First off, you should be using specialsource version 1.2.4 as it is the latest.
Second, combining a paper dependency with a spigot dependency might be the cause of your issue as the two are getting farther from compatible with each update.
Thirdly, are you sure that you are using the right class name?

[quaint mantle]

well about the 3rd issue, i actually cannot find anywhere where i am using net.minecraft.nbt.Tag im only using CompoundTag

[quaint mantle]

i can try get rid of the paper dependency but is there a good way to do that without breaking all my code?

[kind hatch]

There's a website called screaming sandals that can help you with NMS naming changes.
https://nms.screamingsandals.org
I don't think there is a class that's just called Tag. I think it's more along the lines of NBTTagCompound

To the second question, are you using paper specific api calls?

[quaint mantle]

acutally yea i dont think im using any paper specific stuff, let me try make backup of my plugin and remove the dependency

i only gotta replace all the uses of components back to normal

Hi

Help plis

[kind hatch]

You're using the remapped jar correct? You mean back to the obfuscated spigot ones?

[quaint mantle]

no i mean as in paper requires me to use Components for stuff like lore and messages, gotta change all those functions to strings now since spigot uses that

[kind hatch]

Oh, gotcha.

[quaint mantle]

also this stuff in my commands

[kind hatch]

I think spigot has those marked that way. Not sure why it's not recognizing it.

[quaint mantle]

isnt spigot @NonNull ?

[opal juniper]

what the whole thing?

lol

[kind hatch]

Nah, apparently it's NotNull

[opal juniper]

it uses jetbrains so yeah

[quaint mantle]

yea

[opal juniper]

nonnull is lombok

[quaint mantle]

idk why but the jetbrains maven dependency got removed with the paper one

so i added it back

i am getting this error a few times:

org.spigotmc:spigot:1.19.3-R0.1-SNAPSHOT/maven-metadata.xmlfailed to transfer from http://0.0.0.0/ during a previous attempt. This failure was cached in the local repository and resolution will not be reattempted until the update interval of maven-default-http-blocker has elapsed or updates are forced.

also this and a 2 with the remap thing

[chrome beacon]

Don't use http. Use https

Also run BuildTools

[quaint mantle]

again?

oh my bukkit repo was on http

still same errors but it does export

so kinda weird

[chrome beacon]

You mean the overlapping resource?

[quaint mantle]

just the plugin builds without any problem

it runs on the server

[tawdry echo]

someone know how to fix?

While build artifact i get this error

[chrome beacon]

Is that libs directory in your project?

[tawdry echo]

si

[chrome beacon]

If so show what it contains

Also what class are you trying to import

[tawdry echo]

all is exists

[chrome beacon]

And make sure the package is set correctly in that class

[tawdry echo]

all is correct

[quaint mantle]

Also when i build i get 4 files,
The normal plugin, remapped, remapped-obf, and the original
Does an artifact include the remapped version?

[kind hatch]

Wtf. I'm trying to delete these two rows from the database since they are duplicates. Why won't it let me? :3

[chrome beacon]

Use the normal plugin

[quaint mantle]

oh alr, does the artifact use that by default?

[tawdry echo]

what do to i have to it work

[chrome beacon]

Send the class you're trying to import

[quaint mantle]

uhh dont think i should, getting an error when i do

[tawdry echo]

content?

[chrome beacon]

What's the error?

[chrome beacon]

Yes

?paste

[undone axle]

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

[quaint mantle]

it doesnt recognise the remapped classes, as in:

java.lang.NoClassDefFoundError: net/minecraft/nbt/Tag

but when i use the remapped it doesn give me that error anymore

[kind hatch]

Well that's to be expected. If you aren't using the right dependencies, then your IDE can't make sense of what you're writing.

If that's a valid class path under the remapped jar, then you'll have to depend on that.

[quaint mantle]

so do i just use the remapped version or another way?

[hazy parrot]

Looks like you can't run two queries at once lol

Idk why is that the case

[kind hatch]

If you absolutely need that class or want to use sane names, then use the remapped jar. Otherwise you'll have to convert your code to use the obfuscated names that spigot uses instead.

[kind hatch]

That's odd considering it only tries running one.

[quaint mantle]

i really dont like using the default spigot ones, it confuses me too much.

anyways, how can i make that my artifact builds the remapped jar

[hazy parrot]

Just run query manually ig

[kind hatch]

That's all handled by the compiler. As long as you have the special source plugin setup in the pom, then you just need to run mvn clean package

[hazy parrot]

Probably intellij being goofy

[tawdry echo]

i think it isnt problem with class content, all is correct, but while artifact build it cant find any class in project

[kind hatch]

Try restarting the IDE. It could just be bugging out.

[tawdry echo]

i have tried it and still dont work

[chrome beacon]

So you didn't put them in the same place as the rest of your classes?

[haughty storm]

I want to use nms for minecraft 1.19.2 but in my maven dependency it says it can't find org.spigotmc:1.19.2-R0.1-SNAPSHOT.

</dependency>

[chrome beacon]

Did you run BuildTools

[kind hatch]

Did you run BuildTools?

[haughty storm]

yeah

[quaint mantle]

well if i use this it doesnt build the remapped but it uses the normal one

[lost matrix]

With which command?

[tawdry echo]

i guess all paths is correct

[kind hatch]

Wait, are you using the IntelliJ artifacts to build your project?

[chrome beacon]

💀 you're not even using maven

[haughty storm]

java -jar BuildTools.jar --compile craftbukkit

[quaint mantle]

oh yea thtas smart

[chrome beacon]

You need to build 1.19.2

[quaint mantle]

well yea thats how i learned it from some1, cus thats the only way i know how to change the output directory

[kind hatch]

IIRC, you don't need to compile craftbukkit, but rather provide the version you want to build.

[lost matrix]

You need to run

java -jar BuildTools.jar --rev 1.19.2 --remapped

Remapped only if you want to use mojang mappings

[chrome beacon]

?nms

[undone axle]

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

[chrome beacon]

^^ Mojmaps guide

[haughty storm]

ok, thanks. I'll try that

[quaint mantle]

since if i do that it just replaces the current plugin (so it updates) and then i dont have to close the server

[kind hatch]

Oh, well maven is different. You'll want to use the panel on the right hand side to do your stuff.

[quaint mantle]

can i change the output directory of the remapped file?

[thorn crypt]

Hey, what is the best way to get all near block of a player ? Like to get all wool in a radius of 10 blocks

[chrome beacon]

For loop

[kind hatch]

Yes, you can specify it in the pom.

[quaint mantle]

ahh alright

where exactly?

[thorn crypt]

it's the only way ?

[lost matrix]

Get the players Block as middle and then use 3 nested loops iterating over x, y and z
from -radius to +radius

[kind hatch]

I'd recommend setting up your build section accordingly.

<build>
  <defaultGoal>clean package</defaultGoal>
  <directory>../target</directory> <---- This is where you can change the output directory.
  <finalName>YourPluginName-${project.version}</finalName>

  <resources>
  </resources>

  <plugins>
  </plugins>
</build>

[lost matrix]

Then use the middle Block and call getRelative(x, y, z) on it

[thorn crypt]

Ok, I tried to loop block around a player and the tps didn't really liked it lol

[wet breach]

clean shouldn't be used as a default goal. For testing purposes to get things building right its fine, but once that is figured out it should be removed otherwise you lose out on some compiling speed ups

[lost matrix]

Yes if you use a radius of 10 thats 10^3 or 1000 Blocks each tick meaning 20_000 Blocks per second per player.
So for 20 players this is 400_000 Blocks per second.

[quaint mantle]

if i put like "d:/whatever" in the directory will that work?

[kind hatch]

Yes, that should work.

So long as you have permission to write there of course.

[lost matrix]

How often do you need to check?

Ah gtg

[thorn crypt]

Yeah :/

[quaint mantle]

so if i run this it should automatically work?

[thorn crypt]

i need it to be every second 🥲

[kind hatch]

I believe so. I use the play button on the right hand side to run the default goal.

[quaint mantle]

ok well it works but it removes everything in the directory and pastes ALL of the different files

[quiet ice]

I guess you can sort-of temporarily remember recently fetched blocks which reduces lookup times but it won't do too much

[kind hatch]

Really? I was unaware of this. I just got used to adding clean since it would almost always never work upon a second build.

[thorn crypt]

I'll still have to loop the block in case there is new one

[quiet ice]

I'd even say the oppose: You should use clean

I had a project where not using clean would double the size of the jar

[quaint mantle]

• the name only changed the default one not the remapped version

[kind hatch]

Yea, that's what clean does. It removes the contents of the output directory. It's like starting fresh if you have a build that's failing for some odd reason.

[thorn crypt]

wdym ?

[quiet ice]

was about something else

[thorn crypt]

Ok sorry x)

[quaint mantle]

ahh okay, how would i ONLY build the remapped file into the folder?

[kind hatch]

Just use the package command.

[quiet ice]

You can just listen for block changes though and update the cache depending on that

[quaint mantle]

it still builds all the files, and only renames the default one

[kind hatch]

Oh, are you wanting just the compiled jar file to be moved?

[quaint mantle]

yea

only the remapped one

[mortal hare]

finally i fixed my bugs with node autocompleter

it was my fault not paper or bukkits

i just handled it improperly

[kind hatch]

Then you might want to use the maven-jar-plugin instead of changing the output directory.

Also, you'll want to use the normal jar that's not labeled remapped since the specialsource plugin converts it back to the obfuscated names.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <version>3.3.0</version>
    <configuration>
      <outputDirectory>../wherever/you/want</outputDirectory>
    </configuration>
</plugin>

[tawny star]

how to configure kotlin in intellij idea i did everything and it still says kotlin is not configured

[quaint mantle]

do i change the build thing back to package clean

[kind hatch]

You can just change it package. You'd want to remove the <directory> tag that you created since the plugin will take care of moving the jar file.

[quaint mantle]

alright

[hazy parrot]

How did you make project

You can just select kotlin preset in intellij

[tawny star]

i had everything set up in java

[quaint mantle]

this is... weird?
it makes a folder with all the classes in the outputdirectory instead of the plugin file

[hazy parrot]

How do you expect kotlin to work then?

[quaint mantle]

oh sorry

using wrong one oops

[tawny star]

i clicked convert to kotlin then setup kotlin made sure everything was correct and then it always shows me that kotlin isnt setup

[quaint mantle]

alright thanks @kind hatch it works

[tawdry echo]

i created new project with the same classes and now work lol

[quaint mantle]

yea that happens idk why

[wet breach]

it depends what exactly you are doing, but you should always try to setup your build where clean isn't necessary to make it work

[tawny star]

h

[wet breach]

part of the speed ups that you miss out on is caching, maven is smart enough to know to only re-compile what was changed and not everything

but it just depends what exactly is happening in your build process that would prevent being able to take advantage of such things

[haughty storm]

How do I spawn an entity using nms

[eternal night]

why?

[haughty storm]

I want to spawn some sort of indicator behind a wall and I want to use a shulker to do this since I can give it the glowing effect but I only want to spawn it for one player

[eternal night]

Then you don't spawn them at all, you only sent the packets needed

[haughty storm]

Sorry, thats what I meant

[kind hatch]

Not me accidentally deleting half my database entries cause I put in the wrong query. 🥹
Thank god it's a test server.

[vocal cloud]

Sounds like you don't have triggers

[kind hatch]

Triggers?

[dry yacht]

I'd avoid creating an NMS entity myself, as that adds unnecessary coupling. There's CraftWorld#createEntity, which is basically a factory function that accepts a Bukkit entity class. Then, there's Entity#getBukkitEntity, use this wrapper to customize the entity according to your needs. Afterwards, you can just send the PacketPlayOutSpawnEntity followed by a PacketPlayOutEntityMetadata to the player you want to spawn this entity to, instead of adding it to the world.

[quaint mantle]

Anyone know a clean/neat way of requesting tons of user input in java, If i carry on with just using scanner variables etc it's going to end up seriously messy

There must be a better way

[dry yacht]

Just from taking a quick glance at your code, I don't think that it would lag, no. The only thing that I'm wondering about is that you can actually teleport an armor stand from another thread, but as long as that works... you should be fine, xD.

[analog thicket]

Do i need to teleport it from another thread tho?

[dry yacht]

By tons you just mean many prompts, right? Whatever logic you use to create those could just be hidden behind a blocking function, which returns a string and accepts a string as the prompt it displays. Not sure what you mean by the mess it creates.

[dry yacht]

Well, your animation thread is another thread, relative to the world thread. Usually you'd need to re-synchronize, which would then ruin the idea of running above tick-speed. Does it work, did you run the code yet?

[analog thicket]

Yep that works

[dry yacht]

Okay, then there's nothing to worry about! :)

[analog thicket]

Perfect thanks for the help

[quiet ice]

likely through libraries such as picocli

[tawny star]

why does intellij show kotlin is not setup when i clicked setup kotlin and did everything

[quaint mantle]

Just for looped through a list

[vocal cloud]

Use bulkInsert

Use BulkWrite along with InsertOneModel

oh wait nvm read that wrong

[haughty storm]

Ok, thank you. Could you tell me how I send a packet to a player in 1.19. I have tried ```java
player.getHandle().connection

But the connection variable doesn't exist

[mortal hare]

https://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html

[tall dragon]

            Player p = getThePlayer;

            ((CraftPlayer)p).getHandle().whatever

[tawny remnant]

Which one is the full-grown wheat the WHEAT or the LEGACY_WHEAT ???

[quaint mantle]

HIIII

[haughty storm]

and what fnct would I have to use to send a packet

[tawny star]

why does intellij show kotlin is not setup when i clicked setup kotlin and did everything

[kind hatch]

All materials that are prefixed with LEGACY_ are there for compatibility reasons. Use the normal one. (WHEAT)

[opal juniper]

if it is unobfuscated, Connection.sendPacket

[haughty storm]

I believe it is obfuscated for me

[opal juniper]

what version

[dry yacht]

If you - like me - don't want to rely on libraries to do this, I'm afraid that there's no easy route to be truly version independent. What I'm doing is the following: Find the field of type EntityPlayer in the Player's class, get it on the player, find the PlayerConnection field on the EntityPlayer's class and get it on the entity player instance, find the NetworkManger class on the PlayerConnection, get it on the player connection instance, then invoke the packet sending method on the NetworkManager which looks like _(Packet<?>, PacketSendListener) or _(Packet<?>, GenericFutureListener<?>) or _(Packet<?>, GenericFutureListener<?>[]), depending on your version.

[tall dragon]

        Player p = null;
        ((CraftPlayer)p).getHandle().b.a((Packet<?>) Yourpackethere);

latest version is this

[opal juniper]

^

[haughty storm]

thx

[dry yacht]

If you're really going to use this approach, you should centralize it and write your own sendPacket(Player, Object) helper method, to have a single point of change when updating. Don't scatter it throughout your project, xDD.

[haughty storm]

ok, thank you

[torpid blaze]

Hey,
has anyone any idea on how to easily generate a Get-Down map?

That a minigame where you need to just on almost randomly placed blocks about 100 blocks down without dying to fall-damage. Normaly the Map is a cylinder in which the (randomly) placed blocks are.
I thought of using multiple hightmaps and place blocks on different levels. But another question would be how to check if they are in the cylinder.

**Anyone any advice? **

[opal juniper]

Yeah sounds easy

[tawny star]

why does intellij show kotlin is not setup when i clicked setup kotlin and did everything

[opal juniper]

just pick a few y values, choose random x & z coordinates and then use a circle equation to check if they are in the circle, ie:

x^2 + z^2 <= radius^2

[dry yacht]

Depends on how you look at it. If you want a distribution that actually feels random, you're going to have to add more logic than just generating 2D points in a given circle. There will be added constraints like the minimum distance between two blocks.

[opal juniper]

yep but they said randomly

so i said randomly

[dry yacht]

almost randomly, xDD

[opal juniper]

ah, i was looking at the other randomly

[torpid blaze]

Oh, thats good!

[torpid blaze]

yea, a minimul and maximum distance would be nice but not the most importaint one

[rough mesa]

[dry yacht]

Are you requesting help for somebody's plugin in help-development? :-:

[rough mesa]

yes sry

[dry yacht]

The thing just is that I have no idea on how the plugin operates internally, so it's going to be hard to help you out. As already pointed out, this sounds like a name has been too long, either in the tab or possibly even in the sidebar scoreboard.

[mortal hare]

the more i implement my project in decoupled core classes, the more i hate it

[rough mesa]

THANKS

[mortal hare]

its very hard to maintain bukkit compatibility with good performance (i mean it works, but it loses couple of cpu cycles because of the conversions of collections and objects)

[rough mesa]

sry caps

[mortal hare]

also not to mention generics fuckery

that is going on

[dry yacht]

Uhm, I'm not sure that this is how it's supposed to feel, xDD.

Which feature are you trying to make compatible with multiple versions?

[mortal hare]

my main idea was to decouple core from the bukkit api completely (not even an import of bukkit api)

while creating an implementation of bukkit api plugin in a separate submodule

but i think its useless rn

since i dont develop this plugin on multiple platforms

[dry yacht]

Sounds like pessimization to me, xDD. Adding a lot of needless CPU work.

[tawny star]

why does intellij show kotlin is not setup when i clicked setup kotlin and did everything, i can send you the pom.xml file

[eternal oxide]

decoupling is a good design pattern, but pointless unless you plan on multiple server types

[mortal hare]

i think i will merge two submodules

its a cancer to work with independently

[quiet ice]

Basically something that is run when entering the loop

Such as initializing the counter variable (that is the most common use)

im sorry to hear that but im sceptical.

Myeah....
And you think we would believe THAT?

Hi Afghan I'm superman

[tardy delta]

💀

[late sonnet]

[limpid nexus]

So that's why you wear your underpants on the outside, oh its all making sense now.

[quiet ice]

It's because usually we increment by 1 every time we step through the loop fully

[mortal hare]

its an old technique of C programmers, who think that ++i is faster to compute than i++ because it returns your the current state instead of previous one, thus no storing of previous value is needed, thus faster impl can be made

[eternal oxide]

I did that before I was superman 🙂

[mortal hare]

but its not true anymore afaik these days

[limpid nexus]

So we established you are a bit special then.

[quiet ice]

However an increment of 2 is also not all too rare - sometimes you get other loops too

[mortal hare]

it may be different in JVM though

[eternal oxide]

very

maven

[mortal hare]

use gradle

[eternal oxide]

Ant is very old and less and less supported

[quiet ice]

Iterator it = getIterator();
for (Object o = it.next(); n.hasNext(); o = it.next()) {
}

Is also not too rare

[tardy delta]

or put the iterator in the initialisation

[mortal hare]

i prefer:

for (Iterator it = getIterator(); it.hasNext();) {
  Object object = it.next();
}

[quiet ice]

it is not - both compile down to IINC 1

[tardy delta]

i prefer to not use an iterator :)

[quiet ice]

ah, it should be it - forgot to rename it

[mortal hare]

best with iterable objects:

for (Object object : objects) {

}

[tardy delta]

objects.forEach

[quiet ice]

Yes but then we don't make use of the step.

[mortal hare]

who cares 😄

[quiet ice]

Well if you want to demonstrate what it can do it might be useful to not keep it empty

[mortal hare]

i didnt call this a for loop 😉

i said its for iterables

  .stream(iterable.spliterator(), false)
  .collect(Collectors.toList()).forEach

i for the filters or anyMatch/noneMatch and a few maps (convertions)

personally for me, they make code hard to read

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[tardy delta]

are you going to write it yourself or do you need someone to do it?

[proven current]

?

[quiet ice]

Another (at least where I am active in) common usage of for loops is:

for (AbstractInsnNode a = method.instructions.getFirst(); a != null; a = a.getNext()) {
}

I'm new to this, I wanted to ask if someone could help

!

[vocal cloud]

And I did ?ask so you can ask you're question

[pseudo hazel]

you still havent told us what you need help with specifically

[thorn crypt]

Does anyone have an idea on how I can get the distance between me and the player i'm looking at ?

[lost matrix]

ray trace

lol

looks about right

[pseudo hazel]

but they just wanna know how you got it, not the actual answer

[proven current]

I want to write a plugin for privileges, but I don't know where to start 👍

[mortal hare]

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[tardy delta]

dunno what "for privileges" means but you can google a tutorial on how to start ig

[mortal hare]

he meant for perk members

[tardy delta]

dunno what that means either

[proven current]

1.12.2 ?

[mortal hare]

in slavic languages privileged means a donator or smth like that

he wants to make features for donators

[proven current]

prefix

[vocal cloud]

If you want to write a plugin for perks/permissions look into how permissions work, how configs work, and how commands work.

[chrome beacon]

Don't forget to learn java first

[mortal hare]

dont forget

https://tenor.com/view/what-why-huh-steve-harvey-confused-gif-17449734

[chrome beacon]

Knowing the basics is important

[vocal cloud]

Benefit of the doubt. But big doubt

[mortal hare]

oh yas

it feels so good to remove generics from classes

wait

[mortal hare]

doesnt GPL enforce you to have your plugin open source

[quiet ice]

You can work around that through absurd amounts of abstraction

[mortal hare]

tbh i think 99% of the plugins on the market break the GPL license then

😂

[quaint mantle]

quite the way to do it for a simple .distance

considering it's a spigot discord, it isn't clientside

[tall dragon]

that assumes you know the location of the player you are looking at

[tardy delta]

me who knows exactly nothing about licenses and always picks gpl3

[quaint mantle]

Right

[quiet ice]

I always pick MIT or BSD

[quaint mantle]

Forgot about that completely

I retract

[lost matrix]

How else would you get the distance of the player you are looking at

[quaint mantle]

You're right

[tardy delta]

isnt the point of mit that you can do whatever you want with the project?

but you have the mention the author or smth

[limpid nexus]

5 blocks

[quiet ice]

Yeah - more or less

[quiet ice]

It looks more like 6 blocks than 5 blocks to me

[limpid nexus]

RAMBLE!

[hazy parrot]

I don't even think you have to do this

For example pterodactyl is under MIT, dave was like do what the fuck you want, idc, it's mit

[quiet ice]

The above copyright notice and this permission notice shall be included in all

Perhaps not explicitly, but implicitly the author must still be mentioned somewhere through the copyright notice

(I also find it funny that I'm one of the few plugin devs that has added a command to dump the license of my plugin (in that case it was the GPL - so even more fun) to the chat)

[quaint mantle]

Cleanest way to generate a random string of letters and numbers?

[pseudo hazel]

generate a uuid xD

[quaint mantle]

Not spigot

[lost matrix]

Create a String with a-z,0-9 and randomly select chars from it...

[eternal oxide]

UUID is nto spigot

[rare rover]

UUID is java

[quaint mantle]

I was just clarifying I'm not talking about minecraft

[lost matrix]

Well UUID is even more general. Every proper programming language supports the UUIDv3 model

[eternal oxide]

UUID is Java so for anything

[quaint mantle]

I know

[rare rover]

Anyways, how would i spawn a "dropped item" using packets? Cant figure out how to convert an itemstack / material to Entity for the packet parameter

[eternal oxide]

So random letters and numbers, as you asked

a single command

[quiet ice]

Have a dictionary of common combination of letters and then randomly pick a combination depending on how common the combination is

I think it's called a Markov chain? Idk, would need to look it up

[lost matrix]

What do you need this for?

[quaint mantle]

Just creating a random id for person in the database

[lost matrix]

Use a UUID

[pseudo hazel]

sounds like uuid is a perfect solution

[quaint mantle]

Just looking for different ways of doing it

[eternal oxide]

UUID

its what its designed for

[quaint mantle]

kk will do

[quiet ice]

Yeah, UUID is the proper solution there - and markov chains are definitely not the solution

[hazy parrot]

Oh, alright then 👍

[quaint mantle]

do UUIDs work if the server is running in offline mode?

[eternal oxide]

work?

[quaint mantle]

what happens if the online-mode field in the server.properties file is set to false?

[crisp forum]

why don't you just try it lol

[quiet ice]

Well it depends on what UUIDs

[lost matrix]

Then every player that joins will get a random UUID which is connected to his name

[mortal hare]

it generates random uuid

for each player username

and stores them inside usercache.json

until it expires

[eternal oxide]

If two players join with the same name they get the same UUID

[quiet ice]

UUIDs you manage yourself won't matter - but player's UUIDs are selected through the md5 checksum of the player name with some extra characters added as a salt

[eternal oxide]

online the UUID comes from Mojang

[mortal hare]

why would you salt an uuid?

[pseudo hazel]

I dont even think you can join with the same name

wouldnt it just say that that person is already online?

[opal juniper]

if it tasted bad

[eternal oxide]

Two players can join with the same name, just not at the same time

[quiet ice]

no idea - mojang does it anyways though

[pseudo hazel]

well yeah, to the server it is the same player

[quiet ice]

I think the salt is Offline player:

[mortal hare]

you cant join with the same name in the server, even native client would not render correctly since packets would be incorrect

[quiet ice]

protocolwise nothing forbids it

except perhaps the tablist and scoreboard - but that can be worked around

[mortal hare]

well client rejects entities with same uuid iirc

[quiet ice]

doesn't the client only know the EID?

[opal juniper]

yeah think so

[mortal hare]

could be

is there any better way to remove duplicate Strings from the collection apart from using set?

sort is closest that i could think of

[quiet ice]

set is the only efficent way of doing it

[mortal hare]

problem is that i need to convert set to list after that

[quaint mantle]

i am bored

[quiet ice]

staying with list can easily get you O(n²) complexity

[quaint mantle]

HashSet?

[hazy parrot]

It's impl of set

[daring lark]

how could get these slots?
https://cdn.skunity.com/2021/03/6935_fb4be127ab21d785540efc124ed9a94b.png

[quaint mantle]

or HashMap.

[quiet ice]

var var10001 = new HashSet<>(list);
list.clear();
list.addAll(var10001);

[mortal hare]

yea that's what i do currently

[quaint mantle]

set string as the key and array of where the strings are as the value.

[mortal hare]

im thinking if there's more faster way to do this

since i believe that iteration of set could be kinda slow

[quiet ice]

Well you might want to ask yourself why you are using a list in the first place

[mortal hare]

because im forced by the bukkit api 😦

[quiet ice]

For what?

[mortal hare]

setting aliases

[quiet ice]

pft - why care about efficiency there?

You only do it once

congrats - that is basically my code but worse

[mortal hare]

i think i would use this but with fastutils

[quaint mantle]

i mean for converting to the list.

[mortal hare]

since it could use System.copy sometimes

[quaint mantle]

nvm.

i am tired.

[eternal oxide]

aliases?

of what?

[opal juniper]

commands

[eternal oxide]

Yeh optimizing or worrying about performance there is a waste of time

[quiet ice]

Yeah like at most you loose 100 µs every time the server starts up

[opal juniper]

[eternal oxide]

Time you would lose converting to a Set or however you want to process it

[daring lark]

solved

Inventory inv = player.getOpenInventory().getTopInventory();```

[quaint mantle]

i have been writing java code for a while, does anyone ever make a new class and file for that class and keep writing code in that file until there is too much code in that file?

then you make even more files to split up the code?

[daring lark]

wut?

[quaint mantle]

i keep doing that in java.

[mortal hare]

everybody does that

that is called refactoring

[daring lark]

no

i use my main class for everything

[mortal hare]

😄

[quaint mantle]

thing is, i barely ever do that with other programming languages, probably.

[daring lark]

joke...

[quaint mantle]

I've got the same set up for mysql on another project and works fine... For some reason it's connecting but showing null and saying it isn't connected? No errors

[quiet ice]

I embrace monolithic development.
That is there stays there

[mortal hare]

Welcome to the java world where boiler plates adds up at least one hundred lines of code

[quaint mantle]

records_db is a cool name.

?

a database that stores records.

Okay

[quaint mantle]

try running some sql?

[tardy delta]

mine https://github.com/FourteenBrush/xKingdoms/tree/master/src/main/java/me/fourteendoggo/xkingdoms/storage/persistence

[quaint mantle]

Yeah, I get this error now

try connecting to the database with another application, does it work?

yep

Doesn't make sense at all lol

[minor fox]

Does saving the texture properties from a GameProfile make it possible to get a skin without the server accessing the MC textures endpoint?

[quaint mantle]

Anything wrong with this method?

and I just used DI for the classes

So shouldn't be null

[dry yacht]

The textures property on the GameProfile just contains base64 encoded JSON, which contains the URL to the texture sprite. So no, that doesn't cache the actual image data.

[tardy delta]

insert into person_records(entries...) values(values...)

no?

[quaint mantle]

What

oh yeah

you need to specify the columns.

[quaint mantle]

That's not the problem

I use this way all the time, works fine

[minor fox]

If I was able to store the actual image data, would it even be possible to use that?

[quaint mantle]

check mysql version and your jdbc connector, if they are compatible?

Okay

[dry yacht]

Still very, very bad practise. If the columns change, you could mess up heavily.

[opal juniper]

PreparedStatements are better!!

[quaint mantle]

that is not raw sql.

probably.

[tardy delta]

got that from w3schools cuz i was confused whether you actually need to specify the columns

[quaint mantle]

I don't need to specify columns

[tardy delta]

you do

[dry yacht]

Tbh, I haven't ever thought about this. If I had to implement a texture sprite cache, I'd try to intercept HTTP traffic and cache those responses, based on the parameters of the request. Otherwise, you'd probably have to really dig deep into the minecraft server itself.

[quaint mantle]

are you able to connect to the database with another application?

[minor fox]

As far as I know, the server doesn't send the skin data to the player, so you would have to edit the client itself, which is a no go

[quaint mantle]

maybe just make it look like another player joined?

then change the player's display username?

[dry yacht]

What are you trying to achieve? The client itself shouldn't matter to you, does it? It's their IP and their traffic. But yes, you're right, the server itself shouldn't render the sprite anyways. This would just be of interest if you actively tried to render it on a - let's say - map, for example.

[quaint mantle]

just make a call to the mojang api for the skin texture?

[minor fox]

The goal is to save the sprite in whatever format and then somehow apply it to a profile without any contact to mojang APIs

But that seems to be quite the challenge

[quaint mantle]

just use a custom texture pack maybe?

[dry yacht]

Well no, I don't think you'll make API calls if you only change the GameProfile which a later packet is going to serialize to the client. The sprite URL that's in the base64 JSON has to be requested separately too, so if you cache that, your server should be free of extra requests.

[minor fox]

I currently save the base64 and insert it into a custom GameProfile, however I won't get around the rate limit regardless if the client sends a request to the API

Which doesn't make sense to me because I have never noticed a rate limit when playing on servers

[dry yacht]

That's probably because your client and your server are on the same exit node. You cannot compensate for rate limiting on the client side, as the client only accepts the textures URL by design, no way to push actual pixels.

[quaint mantle]

so, i wanted to ask something.

[minor fox]

Yes, so how can I for example switch from lobby to lobby on hypixel and load hundreds of skins without the rate limit being reached

[mortal hare]

cache the skins

[quaint mantle]

does anyone wanna start a collab project of some sort? Any collab project should be fine. I have never really worked on a project with anyone. This might be a good way to learn stuff and also get feedback on how I code. Possibly even try learning things like CI/CD and other real world development stuff?

[dry yacht]

Could you show me an example of how you're currently running into rate-limiting? Are we talking about server-side or client-side issues?

[quaint mantle]

if anyone's not doing anything right now, perhaps?

[dry yacht]

I highly doubt there's a single developer out there with no active projects. That's almost a law of nature, xDD.

[quaint mantle]

i have an active project too lol and i just wanted to take a break from it.

[minor fox]

This is all more of a hypothetical scenario. I'm making a menu with potentially hundreds of player heads

[dry yacht]

Shouldn't be an issue, you just need to cache your textures base64 persistently, as a runtime cache won't cut it, if we're talking hundreds. I have written something similar once, where I had not a single issue... Let me search it up real quick.

[quaint mantle]

i am actually going to be doing something like that too probably sometime soon.

[dry yacht]

https://s4.gifyu.com/images/heads_compressed.gif

[quaint mantle]

how is it that fast?

[tall dragon]

i guess it has them in memory

[dry yacht]

Black magic

[quaint mantle]

anvil GUI, hm.

i will steal that idea, probably.

[dry yacht]

I basically cache all these texture values in a database and load them all on startup. I sacrifice memory for resolving speed.

[dry yacht]

I highly doubt that, xDD. This was not trivial.

[minor fox]

But you don't cache the sprite values, correct?

[quaint mantle]

you are loading your database in memory?

[tardy delta]

ij is doing weird

[pseudo hazel]

I never though about using the player inventory for the anvil ui , but thats pretty clever

so before it opens it does it like store the players actual inventory somewhere?

[tall dragon]

i can still steal it tho

[pseudo hazel]

or how does that work

[quaint mantle]

what other GUIs with textboxes do we have?

[tall dragon]

no problem

[pseudo hazel]

the anvil is the only one

[dry yacht]

Fake updates, otherwise you're gonna screw yourself if you error out

[tall dragon]

signs

but that is it

[quaint mantle]

signs are kind of, eh.

[tall dragon]

signs do not have slots obviously

[quaint mantle]

wait, what about written books?

[pseudo hazel]

okay so packet witchcraft then I see

[dry yacht]

There's no "stealing" it, I'm not the first to write this, xDD.

[tall dragon]

just joking haha

[quaint mantle]

does the text get sent to the server everytime player types something with written books?

[dry yacht]

Nope

[quaint mantle]

but it does with anvils?

[dry yacht]

Books are entirely clientside, they are only sent if you sign the book

[dry yacht]

Yep, one packet per key down

[quaint mantle]

is there an event for that in the bukkit api?

[pseudo hazel]

or if you close it iirc

[minor fox]

Would the textures column be a reference to the textures endpoint then?

[dry yacht]

Yep, that could work too. But most definitely not live, as the chat is also not transmitted live. The only live thing seems to be the anvil.

[pseudo hazel]

yes

[dry yacht]

Would be something along the lines of:

eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNjM3NTVjYmIyNzU3NTgxNmI3ZWE1NTc3NGMzYTdjNmEwYzc5NDVlZDIyYzI0M2NlMTlkNzdmOGNjOWEifX19

Which decodes to:

{"textures":{"SKIN":{"url":"http://textures.minecraft.net/texture/63755cbb27575816b7ea55774c3a7c6a0c7945ed22c243ce19d77f8cc9a"}}}

[pseudo hazel]

which makes sense since it has to update the output item for vanilla

[dry yacht]

But the client could also do that, but thank god they decided to outsource this to the server.

[minor fox]

Right, that's what I store persistently atm. What I don't get is how the client loads all those heads when the limit it 600 per 10 min

[quaint mantle]

so, do player head textures get rendered server-side or client-side?

[pseudo hazel]

if you say rendered, it means client side

[quaint mantle]

hm.

[pseudo hazel]

the server doesnt "render" anything

[dry yacht]

You don't load 600 heads in 10 minutes, very unlikely. You always paginate them. Maybe the client even caches some skins persistently, no idea, as I've never researched the client side of textures.

[quaint mantle]

do player head textures get requested from mojang api server-side or client-side?

[pseudo hazel]

probably server side?

I think the client has to download/cache the textures though somehow

[dry yacht]

The textures URL by UUID is requested serverside, the actual image data by URL is requested client side.

[quaint mantle]

does mojang api not have rate-limiters?

oh.

[dry yacht]

I just wouldn't waste a single thought about clientside rate-limiting, as it's out of your control anyways. Do the best job on the server and call it a day.

[quaint mantle]

ok.

[minor fox]

I guess 600 is more than I thought it would be lol

[dry yacht]

It is, I don't think you'll ever run into any issues on your client.

[minor fox]

Yeah I guess bottom line is cache the texture properties and let the client do its thing

[quaint mantle]

is the texture url different for every UUID and not something that concatenates the UUID in some way?

[pseudo hazel]

every uuid is linked to a url

as per the database

[dry yacht]

.

The texture ID is unique, don't try to find any patterns.

As they store every ever uploaded texture, it has nothing to do with UUIDs.

[quaint mantle]

oh.

[minor fox]

While we're on it, I noticed a value was an exact match of a signature, what exactly do you need the signature for?

[dry yacht]

Which is why there are services which allow you to create custom heads. They just upload an image to one of their accounts, generate a new texture ID and hand that out to you.

[quaint mantle]

hm.

[tall dragon]

you can even use an account you own for that

with either your own, or maybe you have a seperate account

[quaint mantle]

is there no limit to how many skins can be uploaded per account over some amount of time?

[dry yacht]

I completely forgot what that was for, I think it's some encryption stuff. I would just not set the signature, this is an example of how I rebuild GameProfiles: https://paste.md-5.net/comupebipe.java (It's old code, don't judge it, lol)

[dry yacht]

Yeah, that's exactly what that one service does by inventivetalent (IIRC)

[dry yacht]

Maybe there is, but I guess that's abstracted away by webservices who use some kind of round-robin balancer on multiple accounts.

[minor fox]

I have read that signature might be necessary to load fake players, but not for heads or vice versa

Have you had any issues with that?

[dry yacht]

I also wrote my own NPCs, and that worked, so... well... I guess it works, xD

[pseudo hazel]

awesome

[dry yacht]

You just need to try it. But you could also just save the signature value and add it to the property map, that wouldn't hurt and maybe even future-proof your code.

[quaint mantle]

i am bored.

[minor fox]

Well I noticed the decoded base64 has the signatureRequired field, so perhaps it makes extra requests if a signature is needed but not found?

[dry yacht]

Hey there, bored

[quaint mantle]

so, about the thing i asked earlier, does anyone wanna do some kind of collab project?

[tardy delta]

hey bored, im doge

[pseudo hazel]

he bored, im distracted

[dry yacht]

I don't know if the server would actually do that... Maybe it just serializes the GameProfile regardless and the client has to drop it, no idea. Again, you'd need to try. You could check with something like WireShark, if there's any additional request to mojang.

[tardy delta]

straighten up lil soldier

[dry yacht]

Tbh, collabs just don't work out for me, so I'm out on this one.

[quaint mantle]

it might be good for getting some real world development experience.

[dry yacht]

You're going to be best off with just persisting the GameProfile as a whole, I don't think that the signature is time critical.

[pseudo hazel]

so what is fake world development experience

[quaint mantle]

does not necessarily have to be limited to just making a minecraft plugin.

[minor fox]

Been a while since I messed with WireShark, so I'm just gonna store the signature too and hope that it's for the better (-:

[rare rover]

    @Override
    public void replacePlaceholder(Hologram hologram, int index) {
        HologramLine line = hologram.getLines().get(index);
        String text = line.getText();
        for (Player player : hologram.getLocation().getWorld().getPlayers()) {
            String newText = PlaceholderAPI.setPlaceholders(player, text);
            line.setText(newText);
            updateTextFor(line, newText, player);
        }
    }``` would there be a better way? Since this will be executing every like second

[quaint mantle]

i mean working in development teams.

i have sort of just done my own projects.

[tall dragon]

try making a little 2d game, thats pretty fun

[dry yacht]

I'd just persist every piece of information you can get your hands on, doesn't matter if you need it or not. This way, you're doing the best you can and don't have to be sorry later on or - in the worst case - even refetch everything.

[minor fox]

Couldn't agree more

[dry yacht]

Now I'm sad about my abandoned heads plugin, :(.

[minor fox]

Is it available on Spigot?

[tardy delta]

wdym?

[dry yacht]

No, I never released it. The main issue is that minecraft-heads sells it's own plugin to make up for server costs, and they could sue me. I hate depending on the "good will" of others. I'd need to roll my own open source database along side of the plugin, if I want to point it at a source that couldn't get me in trouble.

[quaint mantle]

just some random project to work on perhaps?

maybe a cool minecraft plugin of some sort, a significantly large project?

[tardy delta]

i know this lol

but its kinda dead

[quaint mantle]

i dont mean a minecraft server, necessarily.

i just mean a collab programming project of some sort to work on with multiple people.

[dry yacht]

I'm pretty sure the plugin would do pretty great tho, as it could be a gamechanger for builders. The search/fetch cycle for heads you need would be several orders of magnitude lower than with either their website or even their plugin.

[tardy delta]

id like to do that too, i only have no idea what

[quaint mantle]

maybe a complicated game or something?
