[kindred valley]

actually

no

it does not

[iron glade]

then you're probably returning from the condition before

Add a debug message before returning and see if it runs through

[wintry ibex]

agh help pls

[chrome beacon]

?paste

[undone axle]

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

[wintry ibex]

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

[eternal oxide]

paste teh full log as your snippet shows no actual error

[wintry ibex]

what

[eternal oxide]

oh looks like you have a corrupt file in your local maven

[wintry ibex]

h-how to fix

[eternal oxide]

delete the 1.12.2 folder C:\Users\Nurisantoso\.m2\repository\org\bukkit\craftbukkit\1.12.2-R0.1-SNAPSHOT

[wintry ibex]

bc i have wait buildtools for 20+ minute to run bruh

[eternal oxide]

delete the folder ^ and run buildtools again.

[wintry ibex]

this folder?

[eternal oxide]

if that is the folder I linked then yes

[wintry ibex]

ok

do i need to delete this folder on buildtools folder?

[eternal oxide]

You shouldn't need to.

[wintry ibex]

Ok

[eternal oxide]

just run buildtools again

[chrome beacon]

It can help to remove the old BuildTools files

[wintry ibex]

yeah done, now i just need to wait 20+ minutes

[eternal oxide]

you could probably just run mvn install but I can;t remember the full command

Silly question to ask at this point. Are you using 1.12.2 NMS?

Yay 3 minutes left of backing up my 4 TB of data on my NAS

[wintry ibex]

what NMS

[eternal oxide]

I guess not then

[wintry ibex]

ok

[weak bear]

Hello How can I do a command clickable message pls I try with TextComponent but I cannot create a new TextComponent

[wintry ibex]

ah still same error

[chrome beacon]

What happens when you try to create the text component?

[wintry ibex]

@eternal oxide still same error

[chrome beacon]

Ok now send the full log

[eternal oxide]

same error with buildtools?

[wintry ibex]

yes

[eternal oxide]

Then paste full log

[wintry ibex]

wait

[lost matrix]

Use the component builder from spigot. If you use adventure then the approach is completely different.

[wintry ibex]

this https://paste.md-5.net/aqadilabeq.cs @eternal oxide

[weak bear]

Okay but I dont found the method of Spigot. I use Mohist server

[chrome beacon]

Mohist 💀

[lost matrix]

wtf is Mohist?

[chrome beacon]

A bad Forge + Spigot hybrid with security issues

[lost matrix]

Forge implementing Paper

i see

Back in the days we used Cauldron for this XD

[lost matrix]

Try

Component message = Component.text("");

If you have those methods then i have some extensive docs for you...

[weak bear]

Okay

Thx

[wintry ibex]

tthis my full logs

[weak bear]

That's not work

I dont find the method of Bukkit or paper

[eternal oxide]

looking, but I see no reason for your error

[wintry ibex]

@eternal oxide

so how to fix

[eternal oxide]

um, at prompt type mvn

nope, ignore me

[eternal oxide]

I have to say, I've never seen your error before

[lost matrix]

TextComponent message = new TextComponent("Click me");
message.setClickEvent(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "some command") );
message.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new ComponentBuilder("Goto the Spigot website!").create()));
player.spigot().sendMessage(message );

[wintry ibex]

i type mvn and that happened

[lost matrix]

So you didnt provide any goals and then wondered why it complains about you not specifying any goals? Mysterious.

[eternal oxide]

nah that was me

his error is strange

[wintry ibex]

;/

[lost matrix]

Whats his plan? Didnt follow. This looks like he is trying to compile BuildTools for some reason.

[eternal oxide]

https://paste.md-5.net/aqadilabeq.cs building 1.12.2

[kind hatch]

What's the full command that he ran initially?

[eternal oxide]

his command is fine just java -jar buildtools.jar --rev 1.12.2

[lost matrix]

Delete everything besides the BuildTools.jar
There might be fragments of newer versions interfering
and its --rev

[weak bear]

Error: 'TextComponent(java.lang.String)' is not public in 'java.awt.TextComponent'. Cannot be accessed from outside package

[eternal oxide]

already had him do that

even had him move it off his desktop

still throws that error

same error every time

[lost matrix]

Wrong TextComponent. awt is useless to you.

[eternal oxide]

I've never seen his issue before. Never even mentioned

[wintry ibex]

hm

[weak bear]

Yes but there is not import for TextCompenent which comes from Bukkit

or Paper

Look you PM @lost matrix

[kind hatch]

Maybe he should clear his local 1.12 maven repos?

[lost matrix]

net.md_5.bungee.api.chat.TextComponent;

[eternal oxide]

did that, Had him delete teh folder

um one sec

it was a different file last time

it was the 1.12.2 folder

[kind hatch]

Which ones? The entire .m2? Or only the craftbukkit folder?

[wintry ibex]

craftbukkit

[weak bear]

He is not exist..

[eternal oxide]

Yes, this is a slightly different error

[lost matrix]

Well then you are not using the spigot api

[weak bear]

Yes I think that's true

I dont think so that mohist use spigot api

[eternal oxide]

same cause different files

[wintry ibex]

first error is this

[lost matrix]

Interesting. Try using git bash instead of the normal terminal.

[eternal oxide]

he is using git bash

[lost matrix]

Then use the normal terminal 😄

[eternal oxide]

🙂

[wintry ibex]

still same 😅

[eternal oxide]

run in command prompt instead of gitbash

but

[wintry ibex]

already

[echo basalt]

skill issue

[eternal oxide]

first delete the folder C:\Users\Nurisantoso\.m2\repository\org\bukkit

[lost matrix]

Are you on a mac?

Na C users nvm

[wintry ibex]

Windows 10

[wintry ibex]

bukkit folder?

[eternal oxide]

yes, clean it all out so nothign is old

[echo basalt]

bukkit folder in cache

yeah

[eternal oxide]

and run in command prompt not git bash

[wintry ibex]

ok

i will delete this folder again in buildtools folder

[eternal oxide]

yep, start everything clean

[wintry ibex]

Oke

[kind hatch]

You shouldn't need to in this case.

[eternal oxide]

Best to be safe as nothing else has worked 😉

[fluid river]

clap 4 me

another successful java lesson

[eternal oxide]

oh my, I just took 5 days backing up my NAS due to a failed drive (bought a full replacement set) updated and rebooted it and the dead drive sprang to life 😦

[lost matrix]

F

[kind hatch]

Lol. At least you now have spares at the ready.

[eternal oxide]

Yep, not a lot of use for 5 x 3 TB drives now though. Upgrading to 5 x 6TB

Can;t put them in my PC either as I'm all SSD other than an Archive drive

[fluid river]

F

[eternal oxide]

very F

[fluid river]

never used it, nice guide

learning from random discussion is nice

[hazy parrot]

btw now when you mention it, there is no way to copy some text with click event on component ?

just SUGGEST_COMMAND ig ?

[kind hatch]

I'm pretty sure there is a COPY_TO_CLIPBOARD enum.

[warm light]

Anyone can tell me how can I get the id?

I did this but not working

[lost matrix]

response -> resource -> id

[lost matrix]

Display the result in json format. Makes it more clear.

[warm light]

Its giving org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1] error

[lost matrix]

pipe the stream into a String and print it. I personally would always use the httpclient from java 11 for rest requests

[tardy delta]

probably free

depends on quality

[wintry ibex]

Yessssss

after waiting 1 hour+ my buildtools now no error again

Yeaaaaa

[fluid river]

there's only way lol

player.getInventory().getItemInMainHand()

or OffHand

[lost matrix]

There are several ways. I would go over PlayerInventory

[fluid river]

umm you just code it wrong then

[paper falcon]

would it be possible to make it so whenever a player types a message, I automatically send message in chat as well. Contents don't matter rn I'll modify it.
But I don't want a plugin, ik how to make it, could I modify it in my client, so I'm playing on random servers and when someone chats I chat

do I need to make a whole new client for this?

slash launcher

[vital mica]

Make a mod?

[lost matrix]

You need client modifications for that

[paper falcon]

could you elaborate?

[lost matrix]

client modification = A modification of the client

[paper falcon]

lol

[river oracle]

Forge or fabric

For the normies

[lost matrix]

In theory you could also do packet sniffing and write a 3rd party application which sends back chat packets

[tawdry python]

Hello, I want to create a world whenever the server starts, in case this world already exists, I want to replace it with a new one, can anyone help? any documentation?

[lost matrix]

[undone axle]

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

BungeeCord Chat: https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/index.html

[rough drift]

just mixin into the chat box add event and get the text lmfao

well tbf the client has 0 clue about the sender

it only knows the message

so like

<IkeVoodoo> hey

that's the message

and it has to parse to figure out who sent it

[lost matrix]

Creating a world:

    WorldCreator creator = new WorldCreator("worldname");
    Bukkit.createWorld(creator);

WorldCreator also has a bunch of parameters you can tweak.

Some inspiration for checking if a folder exists and removing a directory recursively

  public boolean worldFolderExists(String worldName) {
    return new File(Bukkit.getWorldContainer(), worldName).exists();
  }

  public void removeWorldFolder(String worldName) throws IOException {
    deleteDirectory(new File(Bukkit.getWorldContainer(), worldName));
  }

  private void deleteDirectory(File directoryToBeDeleted) {
    File[] allContents = directoryToBeDeleted.listFiles();
    if (allContents != null) {
      for (File file : allContents) {
        deleteDirectory(file);
      }
    }
    directoryToBeDeleted.delete();
  }

[robust light]

how can I get the last damager of a player if they fall into the void?

[worldly ingot]

Well, the last damager would be the void 😅

[rough drift]

they probs meant the last human damager

[robust light]

I mean the last player, that damaged the player

[rough drift]

in that case just store a hashmap

<UUID, UUID>

[worldly ingot]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#getKiller()

[rough drift]

and on player damage update it

you can just call #put again to update

[worldly ingot]

That value might be null though because Minecraft only tracks the last player damager for up to (10?) seconds

[rough drift]

the killer could be null

yep

and also zombies

zombies result in null

so do mobs

[worldly ingot]

Yeah because it would be the last damager

[rough drift]

only players are tracked in that method

[robust light]

I used Objects.requireNonNull(player.getKiller()).getInventory().addItem(giveThisOnPlayerKill);
in the PlayerDeathEvent but it doesnt work, any idea why? (giveThisOnPlayerKill is an Itemstack)

[lost matrix]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[robust light]

it just doesnt do anything. Doesnt return anything, neither does it leave any logs in console.

[lost matrix]

Is the listener registered? Did you add the EventHandler annotation?

[robust light]

yeah

[worldly ingot]

(also remove the Objects#equireNonNull(), it doesn't do what you think it does)

Just do a proper null check

[robust light]

if I check if the killer is online, would that be a proper null check?

[echo basalt]

it suppresses the IDE warning and that's all we care about

[lost matrix]

No. This is a check if the player is online. Not a null check.

[civic wind]

Loool so true

[warm light]

I am getting JSONObject["response.resource.id"] not found. ._.

[chrome beacon]

What nbt tag do you want to check for?

[lost matrix]

Did you print out the full response already?

[eternal oxide]

I'm going to guess your request doesn;t account for redirects

[lost matrix]

Thats why i would just use javas httpclient

Instead of opening a random stream on an url

[worldly ingot]

ItemStack#hasItemMeta()

Anyone who has a DataManager/FileManager class with everything normal config has like customConfig#set customConfig#contains

[slim kernel]

Hello! I made a spigot 1.18.2 plugin which works perfectly on my spigot server. But when I put it on my friends Bungeecord Paper Server also 1.18.2 everything works aswell except one method which is only doing some for loops to check if there is a block or not.... Anyone know what the problem could be?

[eternal oxide]

We are supposed to guess from that?

I say sunspots

[lost matrix]

Neutrons from the sun randomly flipping bytes

[slim kernel]

okay thank you I will look at that

thats the method: https://gist.github.com/ItzJustNico/693e809020e408bb0e7b2144c20eb888

[slow wigeon]

Hello

[lost matrix]

Nothing in here is paper specific. We need more infos like stack traces

[eternal oxide]

There is nothing in there which would break on paper

[slow wigeon]

Bro I open spigot and error is coming how to solve

[lost matrix]

Bro. Really? If the error is big then you might have to do some stuff man...

[untold jewel]

xD

[green prism]

How can I obfuscate a plug-in?
I don't need any moral advice

[lost matrix]

#help-server

[lost matrix]

Dont. Not worth it. We had this discussion several times already.

[slim kernel]

whats stack traces how do i get them

[slow wigeon]

I can send my error photo in dicord

[green prism]

Okay, thank you

[eternal oxide]

I'm going to guess that your "friends" server uses a different main world name.

[green prism]

ElgarL is my dad

[floral drum]

cap

[lost matrix]

nocap

[green prism]

no cap

[floral drum]

also why

if something can be obfuscated, it can be deobfuscated owo

[slim kernel]

hmm okay thank you i am gonna check taht

[green prism]

It's hard to deobf

[floral drum]

unless it's variable name/field changing

what are you trying to hide?

[green prism]

an hello world plug-in

[lost matrix]

If you need the "main" world then its safer to call Bukkit.getWorlds().get(0)

[green prism]

Smile

Could you help me?

[lost matrix]

Sure

[green prism]

?paste

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

[green prism]

https://paste.md-5.net/caxicudoxo.cpp
Apparently sometimes players get connected to the new server after 2 seconds, other times, they have to wait 10 seconds, other times 20s
Sometimes instantly

This is after a slot in the destination server is free

[slim kernel]

What would be a not "main" world? Every server only has one right? Even on bungeecord?

[lost matrix]

One more thing:

location.getBlock().getType() != Material.AIR

should be

!location.getBlock().getType().isAir()

Because there are several types of air now.

[slim kernel]

oh okay thank you

[lost matrix]

Bungeecord has no worlds. Its just a proxy to forward packets and has no notion of the actual game.

[slim kernel]

I could fix the world problem through passing a player in the method and getting the world from the player because its always the right one then right?

[lost matrix]

Did you track how often your loop is executed?
Debug the time in ms it takes between each run() execution.

[green prism]

hint:
those are the problem

    public int getMaxPlayers(String server) {
        try {
            AtomicInteger max = new AtomicInteger(-1);
            CountDownLatch latch = new CountDownLatch(1);
            ProxyServer.getInstance().getServerInfo(server).ping(((result, error) -> {
                if (error == null) {
                    max.set(result.getPlayers().getMax());
                }
                latch.countDown();
            }));
            latch.await();
            return max.get();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return 0;
    }```

Idk how to fix

[eternal oxide]

You pass Two Locations to the method,. just get teh world from that.

[lost matrix]

You dont need to. You are already passing two Locations to the method. And those Locations already have a World.

[slim kernel]

Oh didnt think of that thank you

[lost matrix]

Whats erroneous about this method?

[green prism]

CountDownLatch latch = new CountDownLatch(1);

I believe that, the ping action, takes a longer delay sometimes

for returning a response

[lost matrix]

Yes thats the nature of a ping. Thats why you have to pass a callback because the ping might take some time.

[green prism]

what can I do to reduce that delay time?

I'm stuck in this process

[lost matrix]

Nothing

[green prism]

So, any queue plug-in has the same problem?

[lost matrix]

There are a ton of approaches to this like caching the amount or tracking the connected players manually.

[lost matrix]

Nope

Ive written a queue plugin with instant responses. It was event driven and backed by redis topics.

[green prism]

hoW

[lost matrix]

Have a Queue of connections. When a player leaves -> poll the queue and connect the next player.

You can use a PriorityQueue and even force an ordering so you can support premium queues.

Or just a simple ArrayDequeue. First come, first serve.

[green prism]

I'm using a private final Map<String, LinkedList<ProxiedPlayer>> queues;

[green prism]

in a PlayerDisconnectEvent?

[lost matrix]

Ah yes. The LinkedList. The worst possible Dequeue. (But should work)

[green prism]

:c why

[short cedar]

This is not my exact code

but i have something like this

``

String materialName = args[0].toUpperCase();
try {

    if (location.getBlock().getType().equals(Material.getMaterial(materialName)))         {
         // code here to use material
     }

}catch (IllegalStateException e)
{
player.sendMessage("§cYou have to input a invalid material!");
return true;
}

``

and I still get a IllegalStateException error

[green prism]

whats an ArrayDequeue

[dusk flicker]

Google

[lost matrix]

Print the exception

[green prism]

does it exists?

[dusk flicker]

ArrayDequeue is in Java

A simple Google will tell you that

[green prism]

What changes between the two?
Why should I use it instead of LinkedList?

I'm not understanding this

[lost matrix]

Dont worry. Doesnt matter for you.

[green prism]

wdym

[lost matrix]

You can take that quite literally. Do not worry. It does not really matter if you use a LinkedList or an ArrayDequeue in your case.

[short cedar]

even if I print the exception I still get

Caused by: java.lang.IllegalArgumentException: No enum constant org.bukkit.Material.DA

[lost matrix]

Well "DA" is not a Material, is it?

[eternal oxide]

DA is not a material

[short cedar]

but thats what im trying to catch

but it doesnt catch the error, and then sends me an internal error in console saying the thing im trying to catch

[lost matrix]

And thats what you are catching

[green prism]

Going back to before, can I then maintain an estimate of the actualOnlinePlayer per server through the eventhandler? Right?

[lost matrix]

Ah you catch the wrong exception

[dusk flicker]

You are getting a different exception then what you are trying to catch

[lost matrix]

sure

[green prism]

thx

[short cedar]

im using IllegalStateException e

and the error
Caused by: java.lang.IllegalArgumentException: No enum constant org.bukkit.Material.DA

I might be stupid, but I thought those are the same, where can i read up on all the exceptions to learn better

[lost matrix]

https://www.tutorialspoint.com/java/java_builtin_exceptions.htm

thank you

oh i see LMAO

state expection
argument exception

very stupid mistake

Thank you everyone for the assistance

[green prism]

what's playeronjoin event equivalent in bungee?

[vivid skiff]

how can i get a key from a value?

[lost matrix]

Are you speaking about maps?

[vivid skiff]

yes

[eternal oxide]

BiMap

[river oracle]

Uhm I don't think maps provide that function but BiMaps do usual included in Google java api which is provided to you through spigot

[vivid skiff]

I asked the wrong thing, i wanted to say how can i get a HashMap key

[river oracle]

Get the keyset

And filter

[lost matrix]

In theory there could be several keys which correspond to a value.
But if the 1 to 1 contract is bidirectional then you can either use a BiMap
from Guava, use a second Map or store the key inside the value.

[green prism]

what is a bimap

[vivid skiff]

thakns

[green prism]

google, okay, im sorry guys

            plugin.getMaxPlayerCount().put(server, plugin.getConfigs().getConfig().getInt("servers." + server + ".max-player"));



        }```


Doesn't saves into the settings.yml file, could you help me?

```java

        try {
            ConfigurationProvider.getProvider(YamlConfiguration.class).save(config, new File(plugin.getDataFolder(), "settings.yml"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }```

please fourteen

I believe in you pal

[vivid skiff]

How can i get only the text, test from a HashMap keySet and not [test]?

[lost matrix]

[green prism]

Maybe String.join?

[tall dragon]

[pseudo hazel]

what are you doing to get [test]

[lost matrix]

You mean your KeySet contains Strings in the format "[data]" and you want to only get the "data" part?

[vivid skiff]

yes

[lost matrix]

Why do you store the Strings in this format?

[green prism]

yoo guys, at the first strange thing you all reply, to me you didn't even put a reaction to the message :C

[eternal oxide]

He's probably not. He's getting the KeySet and sysout. It will show as that

[vivid skiff]

because i need it for a playerdata where it saves like:

gangs:
gangname:
....

and i need to add a new path to the gang

[eternal oxide]

if he has a single entry

[dusk scroll]

https://pastebin.com/QdtC3X1V
I am getting a nullpointerexception in the addPriceToLore method in my ShopItems enum here.
Where it attempts to get the shop on line 393
I do not understand how this value could possibly be null, as if you check the enum it specifies the shop it's supposed to be getting for each item.
(ex. GOLDEN_APPLE) is what it is trying to get when I get this error.
Does anyone know why it would do that in this case?

[tall dragon]

are you storing the gang name as key?

[pseudo hazel]

well if you inly want one item in a set or array or list, you just use .get(i)

where i is the index of the item, in this case probably 0

[vivid skiff]

It is for a invite command where i need to get the gang name of who invited the player

[worldly ingot]

Just for the record, Sets aren't random accessible so there is no get(int)

[lost matrix]

If the ItemStack had no lore before then ItemMeta#getLore() doesnt return an empty list but null.

[vivid skiff]

                if (gangInvite.containsValue(player.getUniqueId())) {

                    String gang = String.valueOf(gangInvite.keySet());

                    RPGangs.getInstance().addGangMember(gang, player.getUniqueId());
                    player.sendMessage("§4§lGANGS §8» §7Ti sei unito alla §c" + gang + "§7!");```

right now is like this

[dusk scroll]

It's not trying to get the lore, it's trying to add lore using some text i've configured in the enum

in this case, it is trying to get the currency display name from the shop, but it believes the shop is null

even though it is specified in the enum

[lost matrix]

And in order to add lore you need to do what first?

[tall dragon]

so whats the problem....

[eternal oxide]

BadString gang = String.valueOf(gangInvite.keySet());

[vivid skiff]

it gets the gang name with the format [gangName] and i don' t know how to remove the []

[eternal oxide]

as I said, you are toString on a KeySet

[dusk scroll]

I know the error is because it's saying the shop is null. I tried to print out the values as a debug, and it says the shop is null each and every time even though it shouldn't be. Since it is directly specified in the enum for which item it's trying to create

[vivid skiff]

Why?

[lost matrix]

Send the stack trace

[eternal oxide]

You are calling toString() on the Keyset which gives you [] around the keys

[dusk scroll]

https://pastebin.com/rMgP7XDg

[vivid skiff]

How can i fix it?

[eternal oxide]

read the keys properly

[dusk scroll]

As you can see every System.out.println() before it works fine.

But as soon as it tries to print the shop debug, it has an error

[vivid skiff]

I don't know how

[eternal oxide]

you either iterate the keys or you read a specific key

[lost matrix]

item.getShop() returns null

[dusk scroll]

I know that. That's what ive been saying

It should not return null

It is directly specified in the enum for the item

that's what ive been asking the whole time, if anyone would know why that could be

[lost matrix]

Is Shops and enum? @dusk scroll

[dusk scroll]

Yes, Shops is an enum

I can send that too if you want

https://pastebin.com/FQc0yhSS

[lost matrix]

Circular reference

[dusk scroll]

is that not allowed?

i never got any error for that before

What it is doing is

When I click on the menu item to open that shop menu

[lost matrix]

Let me think how enums are initialized

[dusk scroll]

It is basically looping through all the shop items to add them to the gui

The reason it is referencing back to the shop in this case, is to get the currency display name to put in the price of the item

[pseudo hazel]

is the GOLD one the only one that doesnt work?

[dusk scroll]

I only implemented GOLD and DIAMOND into the inventoryclickevent for testing. Neither one works.

For the same reason

[pseudo hazel]

and how is createItem called?

[lost matrix]

Using enums for this is really a horrible design choice. But i can only speculate that you are dealing with a initialisation problem.

[pseudo hazel]

I asume you dont get a nullpointer because of the item.getDisplayName aswell right before addPriceToLore call right?

[dusk scroll]

No, the item displayname works fine

[dusk scroll]

as you can see in the error it prints it out before the error

where it tries to print out the shop as well (was debugging to see what was null and that's how i narrowed it down)

[dusk scroll]

createItem gets called when the GUI is being created. it takes the information for the item from the enum to create an item with the material, displayname, enchants, etc as configured, and even adds the existing lore, then it will call addPriceToLore() to add the price onto the existing lore and then return the new lore so the item can be created

[lost matrix]

Wait is your method called in the constructor of your enum?

[dusk scroll]

No

All those methods are outside the constructor

[pseudo hazel]

it might still be a circular reference though

[lost matrix]

Im also leaning towards this

[pseudo hazel]

because the ShopItems constructor constructs the enum value for Shops, but in that enum constructor you call the ShopItems Item

[lost matrix]

        System.out.println(item.displayName);
        System.out.println(item.getShop());

So this prints
"Golden Apple"
"null"

[dusk scroll]

correct

[pseudo hazel]

this seems like a design flaw

why does the item need to know the shop it came from

shouldnt just the shops knowing what items they have be enough for everything?

[lost matrix]

Yeah its almost certainly a problem with two enums referencing each other

[dusk scroll]

possibly

i think i had some reason but i don't remember it TBH, I did all of this last night 😂

I'll have it provide the shop it's looping through in the method

maybe that will fix it

lol that worked 😃

now ive just gotta change the order of the items and add the interaction back

(im reworking the shop system, previously it was hardcoded into a listener which was pretty trash but now with that at least it's configurable through the enum 😂)

[tardy delta]

Map<Integer, Consumer<InvClickEvent>>?

[lost matrix]

Everything else is fundamentally inferior

[tardy delta]

best thing

[iron glade]

Urgh that texture pack

[dusk scroll]

why do you hate it?

[iron glade]

don't like see through ones

although they can be nice for pvp and minigames n stuff

[prime reef]

just spitballing for a second, but i'm thinking about trying to untangle the game code a little w.r.t threading

[dusk scroll]

for the inventory?

[prime reef]

I despise that I have to use my old username here lmao

[dusk scroll]

i mean yeah that's what it's for

[iron glade]

makes sense

[prime reef]

anyway, game only uses the one sync thread for gameplay shit, then an async for chat, yeah?

[lost matrix]

Yes chat is handled async

[prime reef]

aye

[lost matrix]

*mostly

[prime reef]

guessing that "mostly" has to do with stuff like hover components

but that's a conjecture lmao

and a very raw one at that

anyway, asking since I've got a pretty chunky plugin and while I haven't properly stress-tested it yet, I'm considering ways to reduce or distribute CPU load

aside from cutting down the regular old asymptotic runtimes I mean

[severe marsh]

So I have this function which is supposed to transfer skull item into skull with custom texture:

public static ItemStack getHead(ItemStack item, String url, UUID uuid) {

        try {

            SkullMeta headMeta = (SkullMeta) item.getItemMeta();
            
            GameProfile profile = new GameProfile(uuid, null);

            Property property = new Property("textures", Base64Coder.decodeString(url));

            profile.getProperties().put("textures", property);

            try {

                Field profileField = headMeta.getClass().getDeclaredField("profile");

                profileField.setAccessible(true);
                profileField.set(headMeta, profile);

            } catch (NoSuchFieldException | IllegalArgumentException | IllegalAccessException e) {

                e.printStackTrace();
            }

            item.setItemMeta(headMeta);

        } catch (Exception ex) {

            ex.printStackTrace();

        }

        return item;


    }```

However it always returns normal steve head

[dusk scroll]

you can def offload some tasks to async

but just be careful and considerate

[severe marsh]

Here's the URL: eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvZWQyZDM2NzQ3YmMzZTJjMzdkOTFmYWZlYjU2MjhjZDg4N2ZjZjU0ZWVkNDllY2Y3ZGRjNTRkMjAzMzYzMzNmMCJ9fX0=

[dusk scroll]

since obviously not everything will work in async

[prime reef]

The way I usually see more intensive shit like dungeons/raids handled is honestly just through BungeeCord lmao, as in "let's just have a separate server process that hosts this other world"

[prime reef]

currently doing data writes async because with large player counts, you're saving a shitload of data every 5 minutes or however long the autosave interval is, and that eliminated the hiccup from saving

and there's not really a need to do it sync

[iron glade]

?paste

[undone axle]

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

[iron glade]

Try that https://paste.md-5.net/ocesiwayad.cs

[prime reef]

but I was thinking more uh

and this is obviously complex, I just spent 6 weeks working on something similar for work

basically dynamically partitioning the world based on player density lmao

[lost matrix]

Dont use reflections for that. Spigot has a profile api now.

[prime reef]

then distributing computation load across multiple sync threads

[severe marsh]

1.8 btw

[severe marsh]

thanks, will do

[lost matrix]

?1.8

[undone axle]

https://howoldisminecraft188.today/

[prime reef]

It's sort of a worst-case optimization, like the plugin runs fine rn, but I've never seen it with like 1k people online at once lmao

[lost matrix]

So you forked spigot?

[prime reef]

Nah but definitely considering it

for this exact reason, actually

[dusk scroll]

I'm so tired of people ragging on people for using 1.8 when more players use it and so do the most popular servers in the game 😂

[dusk scroll]

I have a solution that might work for you

ItemStack head = new ItemStack(Material.SKULL_ITEM, 1, (short) 3);
        if (url.isEmpty())
            return head;
        SkullMeta headMeta = (SkullMeta) head.getItemMeta();
        headMeta.setDisplayName(ChatColor.translateAlternateColorCodes('&', name));
        GameProfile profile = new GameProfile(UUID.randomUUID(), null);
        byte[] encodedData = Base64.getEncoder()
                .encode((String.format("{textures:{SKIN:{url:\"%s\"}}}", url)).getBytes());
        profile.getProperties().put("textures", new Property("textures", new String(encodedData)));
        Field profileField = null;
        try {
            profileField = headMeta.getClass().getDeclaredField("profile");
            profileField.setAccessible(true);
            profileField.set(headMeta, profile);
        } catch (NoSuchFieldException | IllegalArgumentException | IllegalAccessException e1) {
            e1.printStackTrace();
        }

        headMeta.setLore(lore);
        head.setItemMeta(headMeta);

        return head;
    ```

[prime reef]

I was initially thinking about just launching a thread for this plugin by itself, but tbh, forking Spigot might not be the worst idea for general optimizations

[lost matrix]

No only a minority uses it. >75% of the playerbase is on 1.16 or higher

1.8 is a bubble

[prime reef]

tbh i don't see why people cling to 1.8 the way they do

i don't know what's so great about it

[dusk scroll]

Server software is more efficient. It's better for PVP too

[prime reef]

i've been playing this game since i was literally 9 years old (older cousin bought it for me as a birthday present in 2008) and idk I've enjoyed seeing it change

i'm now almost 24 lmao

[prime reef]

the PvP part, I get, though it's not my cup of tea

[trim creek]

It uses less resources, and has a better PvP system in Java. Bedrock has the 1.8 Java PvP mechanics.

[lost matrix]

Its horribly outdated. It has many bugs which will never be fixed.
Absolute garbage version which is only played by pvp fortnite kiddies which
wanna hammer their left mouse button real fast. Everything more complex
is too hard to comprehend for them.

[prime reef]

but the server software? I was under the impression they'd actually cleaned up a lot of server performance

I mean just watching the profiler the GC is doing way less work but that might be my launch settings actually

[trim creek]

Wait. How did they buy it in 2008? 💀

[dusk scroll]

My entire experience with the latest Java version has been quite terrible

[prime reef]

...the game had an /indev/?

[dusk scroll]

Everytime there's an issue

[lost matrix]

Sound like a you problem

[prime reef]

Maybe it was 2009 and I was 10, idk

I was a literal child so my memory isn't the greatest

[iron glade]

2009 was early access

[dusk scroll]

I ran a server with it and the memory kept climbing up and up. Like the GC didn't even work. lmao

[drowsy pawn]

hello can help ProtocolLibrary.getProtocolManager().addPacketListener((PacketListener)new PacketAdapter((Plugin)plugin, new PacketType[] { WrapperPlayClientUseEntity.TYPE }) { public void onPacketReceiving(PacketEvent event) { if (event.getPacketType() == WrapperPlayClientUseEntity.TYPE) { WrapperPlayClientUseEntity packet = new WrapperPlayClientUseEntity(event.getPacket()); if (TrollCommandMain.this.names.containsKey(event.getPlayer().getName()) && packet.getType().equals(EnumWrappers.EntityUseAction.ATTACK) && packet.getTargetID() >= TrollCommandMain.this.set.startID && packet.getTargetID() <= ((WatchDogPlayer)TrollCommandMain.this.names.get(event.getPlayer().getName())).getLastID()) { int hits = ((WatchDogPlayer)TrollCommandMain.this.names.get(event.getPlayer().getName())).getHits(); TrollCommandMain.this.names.put(event.getPlayer().getName(), ((WatchDogPlayer)TrollCommandMain.this.names.get(event.getPlayer().getName())).upHits()); if (hits >= TrollCommandMain.this.triggerBhop) { TrollCommandMain.this.btc.addBhop(event.getPlayer().getName()); } else { TrollCommandMain.this.btc.send(event.getPlayer(), "&4&lNETRANKYK, NES BUSI PALAIKOMAS SUKCIUMI!"); } } } } }); this.btc = new BhopTask(this); this.set = new Settings(); plugin.getServer().getPluginManager().registerEvents(new TrollListener(this), (Plugin)plugin); }

[dusk scroll]

Went back to Java 8, no problem

[untold nymph]

Latest versions can still be run extremely efficiently

[prime reef]

but I know I played MC classic lmao

[iron glade]

hello what is problem

[trim creek]

The indev version was released in 2010. The game's first version was released in 2009 (and its original name - Cave Game - has been replaced to Minecraft with that)

[dusk scroll]

you haven't provided us anything except your code. no errors or anything

how can we see the problem with no info

[prime reef]

mb, you're right, it was 2009

if you bought the game you could get a custom skin

[dusk scroll]

oops wrong ping, sorry - that was to @drowsy pawn

[lost matrix]

Im not gonna get into this but if you prefer java 8 then you are standing
right here

[dusk scroll]

Sure and so can the 1.8 versions

[prime reef]

yeah i'm ngl, there was this super hairy ugly period where both spigot and java were kind of shit, and the older versions were just easier to work with

but Java 16+ and the latest game versions are actually really nice

[severe marsh]

Doesn't work

[dusk scroll]

what's the error?

[untold nymph]

1.8 versions are extremely limited API wise compared to newer versions

[prime reef]

error

[severe marsh]

no error

[prime reef]

this. old spigot API sucks

[severe marsh]

it just returns steve head

[dusk scroll]

It's a better learning experience

[kind hatch]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[prime reef]

it's not really a learning experience if you're doing it wrong

[iron glade]

Did you try what I sent?

[dusk scroll]

Learning NMS is extremely valuable.

[untold nymph]

If you actually want to learn spigot dev, starting with 1.8 is a horrible experience nowadays

[severe marsh]

yes

[lost matrix]

Why would you literally cripple yourself with an unsupported, buggy, ancient version from almost half a decade ago?
Its objectively a bad decision.

[prime reef]

NMS is only valuable if you plan on diving into more complex mechanics.

[severe marsh]

@iron glade

[iron glade]

Didn't work too?

[dusk scroll]

1. It's not buggy.
2. It forces you to learn NMS, which is a valuable skill in MC development.

[prime reef]

false

[iron glade]

Are you in offline mode?

[prime reef]

if you have to use NMS nowadays, you're doing one of two things:

1. Whatever you're doing, you're doing it the wrong fucking way, because Spigot has APIs for pretty much everything except modifying mob AI
2. Modifying mob AI

[severe marsh]

tried in both

didn't work

[iron glade]

hm weird, I have no idea if it works in 1.8, it works for me in 1.17+

[trim creek]

And this is something I hate in most people. Most devs prefer every other to use the latest software. Its not how it goes by. As I look into all this, most devs just do not realize, that others has their own minds. If they prefer an older software, they shall use it. I use 1.8 and 1.18, while doing stuff in 1.16 as well. I don't mind if I get no support on 1.8. I just google my problem, and voilá. I typically hate when everyone forces me to do use this and that. No. That's not how its going to work. Just stop being mean telling people they are stupid because they prefer an older software. Each software has its own greatness. And you HAVE TO ACCEPT IT.

[dusk scroll]

It also forces you to learn advanced java concepts like reflection you might not have to use in the later versions

[severe marsh]

okay

it is possible btw, as this command works

/give @p skull 1 3 {display:{Name:"Pumpkin Spice Latte"},SkullOwner:{Id:"9aac9003-8d9b-461d-bcdd-1ffa7b24dc3a",Properties:{textures:[{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvZWQyZDM2NzQ3YmMzZTJjMzdkOTFmYWZlYjU2MjhjZDg4N2ZjZjU0ZWVkNDllY2Y3ZGRjNTRkMjAzMzYzMzNmMCJ9fX0="}]}}}

[dusk scroll]

what values are you feeding to the method

[prime reef]

Honestly, I'm gonna disagree with that as well. The vast majority of plugin devs are doing this shit as a hobby, and the reflection you have to use in NMS really doesn't give you much of a grounding in what reflection is actually capable of

[dusk scroll]

i'll try it too

[severe marsh]

9aac9003-8d9b-461d-bcdd-1ffa7b24dc3a as uuid

[iron glade]

ah no

bad values

[dusk scroll]

It's looking for an actual URL

[iron glade]

use something like (gimme a sec)

[dusk scroll]

Like a texture from minecraft.net lol

[iron glade]

https://textures.minecraft.net/texture/7ec1482c1f16ba37f31167e6fb3731cd4b76317e28186cba363ed3eb81d34c59

[prime reef]

gonna hawk my own library for a sec (https://github.com/Dewynion/EmberCore/tree/dev) so I can say I've had ample experience using reflection at this point

[severe marsh]

\http://textures.minecraft.net/texture/ed2d36747bc3e2c37d91fafeb5628cd887fcf54eed49ecf7ddc54d20336333f0

[iron glade]

input a link of this type

[prime reef]

since one of the main features is basically hooking Jackson into Spigot

[dusk scroll]

right, like that

[iron glade]

yes

[dusk scroll]

Sure, if you are wanting to do this stuff as a hobby, it does not matter what version you use

But if you want to be a professional (like work at hypixel or something) then you should learn all this 1.8 stuff and experience it

[prime reef]

that's a more appropriate use of reflection, all NMS really does is make you comb through a bunch of obfuscated nonsense and waste time.

[prime reef]

idk I work in research at way larger company and I'm pretty sure nobody I work with would agree there lmao

well

for starters they'd ask why the hell I'd want to work on minecraft servers fulltime LOL

but yeah, I dunno, NMS is just a hallmark of shit software design

it's why I strongly advocate for staying up to date on Spigot as much as you reasonably can

[trim creek]

btw wtf is an nms

[prime reef]

net.minecraft.server

[trim creek]

ahh

[prime reef]

it's a package that basically contains the obfuscated game code

Spigot itself is an interface that runs on top of that

basically provides a (mostly) version-independent and human-readable API

[trim creek]

thats probably something i dont have in my latest buildtools jar I decompiled or somehingn. I cannot check TPS with the plugin xd

[prime reef]

iirc you need to explicitly create the craftbukkit jar

which is where NMS code lives

but I could be wrong, it's been a while

[trim creek]

I use the shaded API

(spigot)

idk if it matters

[prime reef]

yeah I haven't looked into that enough to know either

[trim creek]

but if I cannot use it, then probably it doesn't has it

[prime reef]

I'm inferring that "shaded" means "server code shaded in"

but if you can't access nms code, then yeah idk

[trim creek]

its... more complicated, I guess...

I mean... The normal version is less compatible with stuff

[prime reef]

how's that?

[trim creek]

uhh idk

I was not able to use somethjing

I was able with the shaded

• also there is a little difference between the two documents' filesize on space -

I just realized I have the whole Spigot code.

and I can edit it...

xd

The normal doc is 1,32MB, while the shaded doc is 5,39MB.

[severe marsh]

so?

[dusk scroll]

so that's the url you feed it?

and it doesn't work

?

[severe marsh]

ye

[dusk scroll]

ok

let's see

[prime reef]

Out of curiosity: what's the overhead of repeatedly creating/deallocating spigot Vectors?

They don't seem to be pooled

I do a lot of work with vectors, wasn't really sure is all

disclaimer that I primarily work in C++ nowadays so I'm overly conscious of this sort of thing

[dusk scroll]

SkullMaker wsg = new SkullMaker(ChatColor.YELLOW + "Walls SG", Arrays.asList(""),

this is how i use it

[severe marsh]

did that work?

[dusk scroll]

https://pastebin.com/yGHuCm5v

You can make a new class called "SkullMaker" and copy this code and just change the package name if you want...

[dusk scroll]

It works in my use case.

Should work in yours too, as the only difference the url and what name you want

[severe marsh]

let me try your method

[dusk scroll]

you can add lore too if you would like to the item by adding stuff to the array

btw there is no %22 at the end of the url

discord is bugged out lol

[ivory sleet]

ugh

well we have gc

and then soon youll be able to have stuff on stack

but the overhead is minimal unless you allocate millions

[severe marsh]

is this full url?

[dusk scroll]

Yes, just take off the %22 at the end. Discord is bugged out and added it for some reason.

[severe marsh]

It worked

thank you

[dusk scroll]

np

[prime reef]

aight, thanks. don't want to microoptimize for no reason

pretty OOTL on Java GC efficiency

all I know is that it's much better than Python lmao

[hasty prawn]

Doing it by hand is probably better than python

[prime reef]

LMAO

manually taking out the trash

write a new OS that allows you to modify system memory in real time and manually manipulate memory

[hasty prawn]

Exactly, I'm sure you could write that entire OS before Python managed to even run anything

[ivory sleet]

ye unless some dum fuk uses serialgc

if you want so... I actually wanted to make development tools into my OS... lets do it then...

                    economyManager.payPlayer(player, target, Integer.parseInt(args[1]));
                    ChatUtil.sendMessagePrefix(player, "&7You paid &a$" + args[1] + "&7 to &a" + target.getName() + "'s &7account");
                    ChatUtil.sendMessagePrefix(target, "&7Current balance: &a$" + economyManager.getBalance(target));
                    ChatUtil.sendMessagePrefix(target, "&a" + player.getName() + "&7 has paid &a$" + args[1] + " &7to your account!");

                return true;
            }

[dusk scroll]

well i guess we dontk now the structure of his command

[hazy parrot]

and can you send your isInt method ?

[untold jewel]

  public boolean isInt(String string) {
        try {
            Integer.parseInt(string);
        } catch (NumberFormatException exception) {
            exception.printStackTrace();
            return false;
        }
        return true;
    }

[hazy parrot]

it printing stacktrance because you said it to print

lol

[untold jewel]

but it gives An internal error

ingame

[hazy parrot]

because isInt is called

and its printing nfe stacktrace

[untold jewel]

lol ok ill try to remove it, but it worked literally 1 hour ago

give me a sec

[tall dragon]

also why would you return a boolean

why not the number

[hazy parrot]

its check

[tall dragon]

and -1 if failed

hes parsing twice now...

for no reason

[hazy parrot]

that is tru tho

[obsidian drift]

parseInt can return negative 1

[eternal oxide]

they could enter -1

[subtle folio]

How am I supposed to make a new objective for my scoreboard?? lol??

[obsidian drift]

just parse it once and catch an exception there

[tall dragon]

make it return null then

[obsidian drift]

you can’t return a bull int

null

[eternal oxide]

null is likely better, but then you still have a second test

[untold jewel]

ok now you guys type alot and im confused

[tall dragon]

u can if you use the wrapper

[hazy parrot]

Hey, can anyone help me think of some non messy way of doing this:
So I have string in my config that looks like this:

|-
&8---&6%player &3Something&8---
&3%placeholder - &6%timestamp
&3%placeholder - &6%timestamp
&3%placeholder - &6%timestamp
&3%placeholder - &6%timestamp
&3%placeholder - &6%timestamp
&8--------&6%current&8/&3%max&8---------

I want to make it TextComponent and only %placeholder parts clickable (each with different click event), but it seems to bit a little more complicated for me then expected

[obsidian drift]

or just parse it once

[untold jewel]

What is the best solution? I dont want them to put in -1

[obsidian drift]

Don’t use isInt

and in the command try parse

if you catch an exception then send a message to the player and return

[tall dragon]

nah thats a shit solution too. having a method is a good idea

[obsidian drift]

no, it’s not

[tall dragon]

what if he wants to do it somewhere else

[obsidian drift]

why parse twice

[tall dragon]

type that all out?

[untold jewel]

btw i removed the e.printstacktrace and it still gives me internal error

when i type a string in

and not just return the message that says please specify a number

[eternal oxide]

Two methods. Test it's an int and parse it.

safest and cleanest

[tall dragon]

ive always just done something like this

public static Integer parseInteger(String in){
  try{
    return Integer.parseInt(in);
  }catch(NumberFormatException e){
      return null;    
  }
}

[eternal oxide]

you could. store teh result and check for null

so really doing a parse and a test.

no real advantage

[tall dragon]

thats what i would do yea

well you only parse once

[eternal oxide]

yep

[tall dragon]

though i don't know how fast parsing is

[untold jewel]

but how would i check if the number is equal to or less than 1

[eternal oxide]

Integer value = parse(args[0]);
if (value != null && value > 0) {```

[untold jewel]

operator != cannot be applied to int, null

[eternal oxide]

Integer

[untold jewel]

ah yeah

im stupid

ty

[eternal oxide]

fixed in my code 😉

Not sure if auto boxing is the best approach

probably better to keep it as an int and return -1 as suggested before

[eternal night]

cool kids OptionalInt it 🙏

[tall dragon]

i mean used like this in a command is it rlly that bad?

[eternal oxide]

you can't assign null to a primitive

so return -1 is best for not an int

[tall dragon]

thats what i usally do yea

but if he needs to support negative values thats not rlly an option

[eternal oxide]

then its better to test and parse

[pseudo hazel]

I just use Integer.parseInt() in a try/catch xD

[hasty prawn]

Same

It's ugly but I don't parse enough ints to warrant another method for it I guess

[untold jewel]

I understood my code before but now with ElgarL and EpicGodMC advise i kinda do but not quite

and that is very annoying

haha

[eternal oxide]

🙂

[hasty prawn]

What do you not understand about their methods

[tall dragon]

if you want to support negative values your current approach is good

[untold jewel]

            Integer amount = economyManager.parseInteger(args[1]);

            if (amount != null && amount > 0) {
                ChatUtil.sendMessagePrefix(player, "&7Please specify a positive number!");
                return true;
            }
            
                try {
                    economyManager.payPlayer(player, target, Integer.parseInt(args[1]));
                    ChatUtil.sendMessagePrefix(player, "&7You paid &a$" + args[1] + "&7 to &a" + target.getName() + "'s &7account");
                    ChatUtil.sendMessagePrefix(target, "&7Current balance: &a$" + economyManager.getBalance(target));
                    ChatUtil.sendMessagePrefix(target, "&a" + player.getName() + "&7 has paid &a$" + args[1] + " &7to your account!");
                    ChatUtil.sendMessagePrefix(player, "&7Current balance: &a$" + economyManager.getBalance(player));
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
            } else {
                ChatUtil.sendMessagePrefix(player, "&7Please specify an actual number!");
                return true;



        }

so is this ok?

for what im doing

dont want a negative number

and I want the args[1] to be an Integer

[tall dragon]

then change it to a normal int

and make the method return -1 if it fails

[eternal oxide]

int parse(String value) {
  try{
    return Integer.parseInt(value.trim());
  }catch(NumberFormatException e){
      return -1;    
  }
}

// to use.
int value = parse(args[0]);
if (value <= 0) {
  sysout("Must be a positive integer!");
  return;
}```

[tall dragon]

real chads also automatically remove accidental chars in the input string

[eternal oxide]

there 🙂

[untold jewel]

            int amount = economyManager.parse(args[1]);

            if (amount <= 0) {
                ChatUtil.sendMessagePrefix(player, "&7Please specify a positive number!");
                return true;
            }
                try {
                    economyManager.payPlayer(player, target, Integer.parseInt(args[1]));
                    ChatUtil.sendMessagePrefix(player, "&7You paid &a$" + args[1] + "&7 to &a" + target.getName() + "'s &7account");
                    ChatUtil.sendMessagePrefix(target, "&7Current balance: &a$" + economyManager.getBalance(target));
                    ChatUtil.sendMessagePrefix(target, "&a" + player.getName() + "&7 has paid &a$" + args[1] + " &7to your account!");
                    ChatUtil.sendMessagePrefix(player, "&7Current balance: &a$" + economyManager.getBalance(player));
                } catch (IOException e) {
                    throw new RuntimeException(e);
                }
            } else {
                ChatUtil.sendMessagePrefix(player, "&7Please specify an actual number!");
                return true;



        }

[tall dragon]

looks good

tho u dont have to parse again

u got the amount already

[eternal oxide]

you have value so use it

[untold jewel]

yeah

i saw

ahha

ty guys!

I will test and come back if something is wrong

if im allowed :3

[eternal oxide]

We are always willing to confuse more 🙂

[untold jewel]

Haha

exactly

[tall dragon]

[dim palm]

Hello, im using this cuboid class (https://github.com/desht/dhutils/blob/master/Lib/src/main/java/me/desht/dhutils/cuboid/Cuboid.java) to make a faller (image), but i want it to break from up to down instead of down to up.

[viscid ember]

not really coding help but which colour looks better

[tall dragon]

whats ur current code to break it

[dim palm]

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

[tall dragon]

i only see a "build" part

and like 500 schedulers

[opal wedge]

Hey, is there an elegant solution to listen for all block events? Currently I'm trying to use the "BlockEvent" class, but I'm getting the error message you see below.

My goal is to cancel the event depending on the location.

[eternal oxide]

Then you need to rewrite the iterator class

it runs from low to high

https://github.com/desht/dhutils/blob/4eea6ad6302eccdb2cc519ec952257b06558c17a/Lib/src/main/java/me/desht/dhutils/cuboid/Cuboid.java#L694

[untold jewel]

ElgarL

How would I send a message to the player that they have to specify an actual number when using your parse method?

like where do I put it

[eternal oxide]

you do that in the method you called it from

[hasty prawn]

You have to listen to them individually afaik

[untold jewel]

but there I did if (economyManager.isInt(args[2])) {

} else {
player.sendMessage("has to be a number")

[opal wedge]

okay, no elegant solution :/

[hasty prawn]

You could probably make a custom event that is fired when any other BlockEvent was fired

You'd still have to listen to all the events, but all you'd be doing was firing another event, so probably a little cleaner.

[dim palm]

What do i need to modify? (i have 2 months learning Java and spigot)

[eternal oxide]

the iterator runs from a low value to a high value. You want it to run the opposite way to give you blocks from high to low

Simplest would be base + size and reduce size until size == 0

just from a quick look

its only the Y you neeed to reverse

[tall dragon]

you could also use reflection to do this.

but that cant really be called elegant 😄

[opal wedge]

haha

[modest garnet]

anyone know whats going on here

[hazy parrot]

google that

[eternal oxide]

Class.forName("com.mysql.jdbc.Driver"); or something close

[worldly ingot]

Depends on the version of your driver

[eternal oxide]

coiuld be com.mysql.cj.jdbc.Driver

[worldly ingot]

Correct

[eternal oxide]

if v8

[modest garnet]

wait sorry?

little lost

[eternal oxide]

You need to initialize teh driver

[grim ice]

2 imo

u shouldnt change the name color with tiers for items imo tho

[modest garnet]

?

[eternal oxide]

add Class.forname.... before asking for a connection

you only need do it once at startup

[viscid ember]

so im not its just i didnt know which one to choose all tiers will be the same colour its just the name changing
Dark Staff T1
Dark Staff T2 etc

and now im trying to work on a combo system

[modest garnet]

so Class.forname(connect())?

[viscid ember]

where with each tier a new combo gets unlocked

[eternal oxide]

no

[grim ice]

Why would you use forName though

thats only for jdks under 6

[eternal oxide]

it just makes sure the Class is loaded

[viscid ember]

im confused why its not letting me push?

[tall dragon]

u did not commit anything

[viscid ember]

i did tho

[tall dragon]

looks like u also need to define ur remote repo

[viscid ember]

i wasnt logged onto my github

🤡

[tall dragon]

[tawdry python]

Does anyone know how I can create a world using WorldCreator, but this world can only have bedrock on tier 1?

[eternal oxide]

You have no driver

are you using Spigot?

[modest garnet]

no JDA

but i thought it didnt matter as its just sql

[eternal oxide]

Then you need to include a MySQL driver

Spigot includes a driver. You are not using spigot so you need to provide your own driver

[modest garnet]

oh mb, ok ive fixed that now

[modest garnet]

sorry to bug, do you know how to build a JDA plugin?

[eternal oxide]

no

[hazy parrot]

They have full pom example on github

[high pewter]

I made a thread a few days ago sorta related to this but I got no responses so thought it would be a good idea to ask my new question here. Is there a way to use IntelliJ's debugger for Spigot plugins?

[untold jewel]

https://www.youtube.com/watch?v=AWsiQIZVU5s

maybe this helps

[tall dragon]

yes there is

really easily actually

[high pewter]

I'll have a look, thank you!

[tall dragon]

all you need to do is create a remote jvm debugger & intellij will give you some commandline arguments in there. you add those to your servers startup script

and boom ur done

[untold jewel]

BOOM

[high pewter]

Never heard of a 'remote jvm debugger' but I think I understand how it would work and ye that makes a lot of sense. So instead of making IntelliJ run our testing server, we make our testing server run IntelliJ (well, it's debugger)?

[tall dragon]

uhhh

not entirely

you bassically just open a port on your server

and intellij uses that

in intellij you need to add a run configuration

and select remote jvm debug there

[high pewter]

Ah, makes sense! I'll have a go 😄

[tawdry python]

I'm trying to enchant an item with fortune 4, and it's saying I can't because I can only enchant 1-3, how can I get around this?

[quiet ice]

As far as I know JVMTI might even be supported without much more configuration

But considering that I never used it outside of the IDE's debug env I never bothered checking out if it really is possible to use it like I think you can

[tall dragon]

is that a programming question?

or a server question

[quiet ice]

?jd-s

[undone axle]

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

[tall dragon]

yea it is possible like that geol

[quiet ice]

Use https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/ItemMeta.html#addEnchant(org.bukkit.enchantments.Enchantment,int,boolean) with ignoreLevelRestriction set to true if this is a programmatic question

[tall dragon]

all you need to do is create the config, copy the cmd line args it gives you and add that to your startup script

[high pewter]

The video seemed to show it working would having to set up a remote jvm debugger or adding any commandline arguments which is strange but I'm not gonna complain about 😅 Sadly, I thought this would also solve the issue of having to copy the JAR to the plugins folder, but the video got around this using build artifacts which afaik means I won't be able to test any Maven configuration

[tall dragon]

you can also achieve that with maven

[high pewter]

Is there a way that doesn't pollute the pom.xml and can be copied between projects? I'm aware that it's possible, but it's just slightly more annoying

[tall dragon]

  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-jar-plugin</artifactId>
      <version>2.3.1</version>
      <configuration>
        <outputDirectory>/my/path</outputDirectory>
      </configuration>
    </plugin>
  </plugins>

like this

[high pewter]

Yeh, but then that pollutes the pom.xml. I don't want to be including the path to my testing server every time I push to GitHub 😅

I know it's really fussy, but it's annoying me cos I feel like there's got to be a better way

[tall dragon]

how else are you going to specify a path

i always just copy my jar manually

[high pewter]

Well, one thing I tried was having my run configuration run a batch file which takes the path as a parameter. But to make this easy to copy between projects, I wanted to use Maven properties to get the path of the JAR to copy, but it doesn't seem IntelliJ allows Maven properties in run configurations

[eternal oxide]

my test server pulls a new jar at startup

[hybrid spoke]

just make a profile in intellij for a test server

if thats the topic

didnt read

[tall dragon]

this tha topic.

[high pewter]

There's also Maven's build profiles (settings.xml) which seems perfect for this, except that profiles made in settings.xml can't configure anything inside <build>, including build plugins

[hybrid spoke]

i mean what is exactly meant by pollute

you can have a parent pom and inherit from that

[sterile token]

Yeah

[high pewter]

imo, the pom.xml should be effective for anybody who uses it on any computer. I'd consider anything inside the pom.xml which only works on one computer/filesystem 'polluted'. Since not everyone has their testing server in the same location on their computer (or would want the JAR to be copied to it in the first place), this includes that.

[hybrid spoke]

you normally dont have test stuff in your pom anyways

[tawdry python]

I use 1.8 and can't find it, maybe not in 1.8?

[tall dragon]

well you could also just build with an extra argument. for example mvn clean package -DoutputDirectory=<path> iirc

[high pewter]

Again, sorry that I'm being really fussy, I'd honestly be quite happy to just manually enter the JAR's location for each of my projects, it's just bothering me that there seems to be so many ways that get so close to solving this but then reach a dead-end

[sterile token]

Are u using maven or gradle?

[high pewter]

Wait, does that work without having to set variables in the pom.xml? All the solutions like this that I've seen do it by having that argument set a variable in the pom, essentially doing the same thing

[high pewter]

Maven

[tall dragon]

one way to find out

[sterile token]

For maven you can use:

<outputFile>path</outputFile>

That worked for me

[tall dragon]

he doesnt want that

[sterile token]

I now there is a way but im not sure since im not on my home and i dont have a pc

What does he want?

[tall dragon]

a way to do this that would work on any pc

and not everyone has their testserver in the same location

[high pewter]

I tried this. It didn't come up with any errors or warnings, but the JAR still outputted to the default location, so I guess it does just act as a property to use in the pom.xml

[sterile token]

WHAT. ARE. YOU DOING. ?

[tall dragon]

uhh yea configurations aint gonna work with maven like that

[high pewter]

Hm?

[sterile token]

Sorry my cellphone its not working okay

I mean I wanst mad

[tall dragon]

@high pewter try adding

<build>
    <directory>${dir}</directory>
</build>

in your pom

[sterile token]

What he wants

[tall dragon]

note that this method does require you to always specify a path on command line

[sterile token]

Does he want to run a server directly from Intellij and have the plugin jar already setup inside the plugin directory

🤔

I dont really understand what he wants...

[high pewter]

I think that works if you use -Ddir="path". But ye, being required to set it to run the Maven goal is annoying

[sterile token]

Yup

[tall dragon]

yea indeed

u would use Ddir

[sterile token]

But what the fuck you want to do bruh

[tall dragon]

i mean there arent many other options really haha

[sterile token]

😡

[high pewter]

Dang 😕

[sterile token]

What is he doing

😂 😂 😂

[tall dragon]

he simply wants the plugin in the plugin folder in a way that works on any pc

xD

[high pewter]

Give me a chance to explain it lol

I'm wondering if there's a way to easily test plugins (so package the plugin and run a testing server with the plugin) which can be applied to any project (don't need to copy the build directory for every project, just enable a run configuration for example) but without polluting the pom.xml (I want all my plugins to be open-source and I don't want to include stuff involving my testing server whenever I push to GitHub)

[eternal oxide]

https://www.spigotmc.org/wiki/intellij-debug-your-plugin/

[high pewter]

I'll have a look, thank you!

Sadly not what I'm looking for, but it explains that there are different methods for debugging (local or with remote JVM) which clears up something I was confused about earlier, so thank you!

[humble tulip]

That's what you're looking for though

Wait do you mean you don't wanna build to your server directory?

Do you habe intellij ultimate?

[high pewter]

No? The only mention of building the plugin is at the very bottom

Build your releases by building the artifact or compiling your maven plugin

[high pewter]

No, but I'm kinda curious now what it has that would solve this lol

[humble tulip]

https://stackoverflow.com/questions/25968099/configure-intellij-idea-to-run-batch-file

You can create a debug configuration that runs a bat file which copies the plugin to plugons after build

As well as runs the server

Just don't commit the bat file

[high pewter]

That doesn't require IntelliJ Ultimate 😅 But ye that's something I've tried, but the thing I'm stuck with there is if there's a way to automatically get the path of the JAR to copy from. I was hoping I'd be able to send this ${project.build.directory}\${project.artifactId}-${project.version} as an argument, but IntelliJ doesn't seem to allow Maven properties to be used for run configurations

[humble tulip]

Ohh

Hm

Well you don't need the build directory because i doubt you're changing it much

[humble tulip]

You can just setup the bat file to copy PluginName-versionhere.jar

[sterile token]

Why dont use docker

[humble tulip]

Use regex to make it so that it can copy any version

[high pewter]

But the build directory would be different too

[high pewter]

Every project has a different build directory

[sterile token]

Oh lmao

Dont over-kill yourself

[humble tulip]

There's probably an easier way to do it tbh

[sterile token]

Oh minion nice. To see you

[humble tulip]

I just don't know it

[humble tulip]

Nice to see you as well

[high pewter]

ngl I'm surprised nobody has said that already 😂

[humble tulip]

I've been very busy with school

[sterile token]

Me too

[ivory sleet]

Well not really

Many attempts have been made to create some canonical convention

For instance maven with its target dir

[sterile token]

Yes

In other words he want to make weird things

[high pewter]

But the target dir is still relative to the project directory itself

[sterile token]

Hey mare

Its not posible

Just forget about that

This channel is more for other type of support

[high pewter]

Fair enough, sorry

Oh ok

I understand

You are talking about plugin Messaging channel

Its sent and receive by a player connection

Thst why it doesnt work when a player its not online

I explain

When you write thru spigot to bungee you the player connection is used to sent a packet

[hazy parrot]

bumping a little

[sterile token]

Patient

@quaint mantle look dm

Yes

spigot -> get the player connection -> send a plugin Messaging channel to BungeeCord channel or your custom channel

[torn oyster]

i only just learned that you can cast/use instanceof on this

is that a problem

[jaunty crag]

How can I slowly create a message and then send it to the player

like im running a for loop to get certain colors and I want to add to a piece of text that will be sent to the player each time the loop runs and then send it to the player

any help appreciated

[tall dragon]

so in the end its 1 message?

[jaunty crag]

yes

[tall dragon]

use StringBuilder

[jaunty crag]

can I add ChatColorto that?

[tall dragon]

i would just use the translated color codes

like &6, &5 etc

and translate it when done building

[jaunty crag]

I cant in my use scenario

[tall dragon]

why not?

[jaunty crag]

I am getting colors from a bufferedimage and then applying them

i need to use ChatColor

[tall dragon]

ah well

you should be able to yes

[jaunty crag]

Ok

[torn oyster]

how would I get an enchantment from a string formatted like "ENCHANTMENT:LEVEL"

well, i know most of it

but how would I get an enchantment enum value from a string

there isn't a .valueOf

[tall dragon]

well thats hard to believe

since that is part of enum itself

[fresh timber]

How do I make command arguments with acf commands

[torn oyster]

there's only .values()

[tall dragon]

should use this https://hub.spigotmc.org/javadocs/spigot/org/bukkit/enchantments/Enchantment.html#getByKey(org.bukkit.NamespacedKey)

[upper vale]

enchantment is not an enum

[tall dragon]

yeaaaa

my bad
