Oh boy it's time to teach dependency injection

Are you familiar with what a constructor is?

Anyway, you want to get rid of all that static, all of it. static is evil, you want to do basically this from the examples 👇 but with your classes

[neat pier]

FAQ Answer:

Dependency Injection
Dependency Injection is a way of providing objects with the objects they need ("dependencies"). This is usually done with a constructor, but can also be done for individual methods

[rigid mountain]

Ok, so i shouldnt use a Main instance, instead pass in main into the constructor?

[lyric gyro]

correct

[rigid mountain]

Ok, let me change that rq

So like this:
Guild data: https://paste.helpch.at/lumawiveza.cpp
Main: https://paste.helpch.at/etizahuhub.java
PlayerEvents: https://paste.helpch.at/azebaxedol.java

[lyric gyro]

That looks much better except that it doesn't compile lol
that new GuildData(this) shouldn't be needed, and you need to pass this when calling new PlayerEvents 😄

[rigid mountain]

yeah i noticed that after i copied it lol

let me try this and see

Still getting the same error

idk where it is coming from

[lyric gyro]

hm, how are you building your plugin?

[rigid mountain]

With maven

https://paste.helpch.at/amiducasas.xml

[lyric gyro]

ah, you need to put <scope>provided</scope> for the guilds dep too, you're probably shading it (bundling it inside your own jar) and it's doing pretty nasty things

[rigid mountain]

Ok, let me try that

Same error even if i add that

[winged pebble]

And it's in the plugins folder?

[rigid mountain]

the guilds plugin?

https://i.imgur.com/YGRDS2V.png

yep and all dependencies

[rigid mountain]

Any ideas?

[night ice]

Are u shading the api?

[dense galleon]

What's the directory holding the enchantment glyphs?

[rigid mountain]

no j sdded scope provided.

[night ice]

could you paste your entire pom here?

U might be adding realocation on dependency plugin

[mint trail]

help with deluxe tags for some reason when i use rgb and mutliple colors and things like that
for example &#c745ff&lN&#ff15e8&la&#c745ff&lm&7
it isnt just "nam" in colors
it look like this "&n&a&m" with colors and it really fucked even tho when i type the same thing in chat normaly without it using the plugin is look fine
and i have no idea what to do

[night ice]

add scope as

<scope>provided</scope> on guilds and try a clean package

[rigid mountain]

Im still getting the same error

[night ice]

btw, how are you building your plugin?

[dense galleon]

can I sort a Map based on the return value of a method of the items present in the keyset of the map?

[sterile hinge]

what

[dense galleon]

Say I got a map Map<Enchantment, Integer>, and the Enchantment class has a method getWeight() which returns an integer

I want to sort the map based on what each object in the map returns using that method

enchantMap.keySet().stream().sorted(Comparator.comparingInt(o -> o.getWeight())).forEach(enchantment -> System.out.println(enchantment.getDescriptionId())); I tried doing this

[sterile hinge]

use a TreeMap with a custom comparator

[dense galleon]

But it didn't do much

When I tried using a TreeMap it complained to me saying that Enchantment is not a comparable item

[sterile hinge]

note that a tree map has other asymptotic characteristics

[sterile hinge]

yes that's why you need a custom comparator

[dense galleon]

How would I make a custom comparator..?

[sterile hinge]

something like new TreeMap<>(Comparator.comparintInt(Enchantment::getWeight)); should do the trick iirc

[dense galleon]

Oh wow okay I didn't even think of that

[warm wing]

anyone know how I could access a variable from another class?

[dense galleon]

That doesn't automatically sort the map though does it

I gotta do the whole keyset().stream().sorted() thing

[sterile hinge]

it should keep the map sorted the whole time

[night ice]

You would need to implement Comparable interface

[dense galleon]

Well, it doesn't seem to be sorted 😅

[sterile hinge]

(as long as the weight does not change)

[dense galleon]

or maybe it is hold on

I'm dum, gotta double check

[queen plank]

I try to copy a section of blocks, WE-like. However, I can't figure out how to copy double chests. Regular ones are fine, but since there are two blocks idk how to get the other one for a Block instance. I know there is a getLeftSide and getRightSide but how do I know which one is which?

[dense galleon]

Is it possible to have two sorters

If there's like 5 items with the same getWeight() value, it should sort based on another value

It's another int

[sterile hinge]

.thenComparing[Int/Double/etc](...) or something like that on your comparator

[dense galleon]

Oh that's cool

uhm something's up

When adding the thenComparing, for some reason o is no longer of type Enchantment according to my IDE

[sterile hinge]

yeah type infering isn't strong enough there, you can write it as .<Enchantment>thenComparing though

[dense galleon]

Ahhhh I was so close to figuring that out

Alright

[rigid mountain]

Im building a clean package with maven

[lyric gyro]

hey where do i place the command: so it would work
left/right click

[viral star]

[graceful hedge]

[rigid mountain]

Still having this issue if anyone has any ideas

[sharp cove]

When i am changing my minecraft plugin to 1.18 i get this error when i try compiling:
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project Kingdom: Compilation failure An unknown compilation problem occurred
https://www.toptal.com/developers/hastebin/ihohuyihes.xml <-- My pom.xml

[winged pebble]

First thing you should change is don't include spigot twice

You only need to include spigot if you already have that then you don't need spigot-api

[sharp cove]

Oke thank you

[winged pebble]

You also don't need the online repo if you have it installed locally (which you probably do if you have the spigot artifact)

[sharp cove]

Yeah but i only want to solve my error tho

[winged pebble]

What else does it say?

[sharp cove]

Thats the only thing

Thats the weird thing too haha

Maybe changing the java version

But how?

[winged pebble]

Your version in the pom is set to 8 rn

But I feel like if that was the issue, it'd give you a better error message

[rigid mountain]

Question, im trying to make some quests, but im wondering how i should track the progress of each quest?

[rigid mountain]

Nvm, i figured out a way, but now i have an optimization question.

So the quests are configureable so im loading them from config, and currently i do it like so:

            QuestType type = QuestType.valueOf(config.getString("blacksmith." + key + ".type"));
            int amount = config.getInt("blacksmith." + key + ".amount");
            String m = (config.isSet("blacksmith." + key + ".id") ? (config.getString("blacksmith." + key + ".id")) : null);
            int karma = config.getInt("blacksmith." + key + ".karma");
            String name = config.getString("blacksmith." + key + ".name");
            List<String> lore = Utils.color(config.getStringList("blacksmith." + key + ".lore"));
            List<String> commands = config.getStringList("blacksmith." + key + ".commands");
            String area = config.getString("blacksmith." + key + ".area");

            Quest q = new Quest("blacksmith", type, amount, m, karma, name, lore, commands, area);
            blacksmith.add(q);
            allQuest.add(q);
        });```

While this works, if i were to do this for **every** player i have a feeling it will get intensive. So once i create these objects, and store them in a list is there any way to basically duplicate that list, but with different object ids? Duplicated each object? or is there a better way of doing this?

[dusky harness]

How do I delete a plugin after the server stops?
deleteOnExit doesn't seem to work 😕

I remember seeing a plugin auto updating itself and deleting the old version... but I don't remember the name of the plugin D:

If I add a shutdown hook (to unload the plugins that I want to delete after they unloaded), then I get this error: IllegalStateException: zip file closed
although the code inside (I added a print to test) works

[lyric gyro]

put the new file inside the ./plugins/update folder

the server will replace it on startup

[dusky harness]

waaaaaaaaaaaaaaait what

[lyric gyro]

update or updates, hold on

yes, that's a thing

[dusky harness]

😮 😮 😮 i never knew

wait

so spigot automatically removes the old jar?

oh wait no

[lyric gyro]

there's an "update-folder" setting or whatever inside bukkit.yml, check that

[dusky harness]

Lightbulb.png Note: Ensure the name of the .jar in the update directory is the same as the name of the .jar in the plugins directory for the same plugin.
hm

[lyric gyro]

that's where you put the new file

[lyric gyro]

paper changes that by replacing the plugins after their name, not file name 😌

[dusky harness]

plugin.yml name?

[lyric gyro]

yes

[dusky harness]

😮

oh is it only 1.18

Hmmm

not that i use other versions

but if other people use it

its limited to 1.18

¯_(ツ)_/¯

[lyric gyro]

then uh.. save the new file with the same name as "this" file?

idk lol

but yeah that's actually a really neat feature very few people know about

[dusky harness]

yep

ty

although for solving the issue without requiring the same file name, maybe I could disable & unload the plugins... manually in onDisable? 👀

hmm

[lyric gyro]

uh

why...? the server is already unloading

[dusky harness]

so that I can delete the jar file

on windows

the disablePlugin method has a check to see if it's enabled

so I think that disabling other plugins in onDisable shouldn't cause any issues

[lyric gyro]

uh.. and how does that solve anything?

you're unloading other plugins

[dusky harness]

then i can delete the file 😃

(after running some code that plugman uses)

(or plugwoman)

[lyric gyro]

deleting your own file
after disabling other plugins
from code that is inside your file
currently open and running?

[wintry grove]

wack

[dusky harness]

no i mean

deleting other plugins files

but once i disable

it shouldn't be running anymore

i think

[lyric gyro]

on newer versions their class loader is closed when disabling it, that isn't the case in older versions
unless you're using paper

[dusky harness]

hmm

is it possible to do that in my plugin?

close the classloader

noo why 1.13+

plugwoman

https://i.imgur.com/vWEVPGu.png

ah well

plugmanx supports 1.8

¯_(ツ)_/¯

[lyric gyro]

yeah, you just need to get their PluginClassLoader and call .close

[dusky harness]

oh

will that unlock the file?

in windows

[lyric gyro]

dunno

oh and in newer vesions the library loader class loader isn't closed so uh

basically you're in for a ride

[dusky harness]

library loader?

👀

[lyric gyro]

yes, the libraries thing in the plugin.yml to download libraries on startup form central instead of shading everything

[dusky harness]

oh

aaaaaa

wait

well that will be in the server classloader

wouldn't it?

[lyric gyro]

no, it's a separate one

[dusky harness]

but that would mean it's separate from the plugin

i think

[lyric gyro]

it is, but those libraries could contain references to classes from your file

[dusky harness]

True

hmm

ill just make it so that if the file deletion errors out, then it'll just skip it until I find a solution 🥴

[lyric gyro]

just put the file in the updates folder lol

[dusky harness]

oh i could do that

ill make the backup solution

🙃

[lyric gyro]

[dusky harness]

(since i want to support older versions)

(and the paper thing is only 1.18)

[lyric gyro]

it's just that good

[rigid mountain]

Anyone?

[dusky harness]

oh wait nvm the issue was that I was running deleteOnExit on null (nullcheck)

deleteOnExit does indeed work 😃

[dusky harness]

except for LuckPerms

all the other plugins work tho

[limber hedge]

How do I get CraftItem to work on 1.18?

final CraftItem craftItem = null;```

Isnt working anymore, it worked on 1.17

[sterile hinge]

It’s not part of the API

[broken elbow]

anyone ever used VectorDrawable? I need spoon feeding. I need a Z letter that doesn't look like this xD https://i.imgur.com/iGZlACj.png. my first time working with this

[broken elbow]

got to this. its not perfect but might have to stick with it for now https://i.imgur.com/iouWUYI.png

oh turns out I can use numbers with decimals. that's helpful

[dense galleon]

Noob question incoming

Does a tree data type exist in Java? When looking it up online, I see most people create their own implementation of Trees

[solemn ocean]

anyone knows why if I do
player.damage(60);
i get 60 dmg but if I do
player.damage(60,entityDamager);
where entitydamager is a entity reference it deals only 31.0?

[hoary scarab]

Yes Tree and Leaves

[wheat carbon]

not that I know of, what's the use case?

[dense galleon]

Making a mod which changes the random enchantment system to a tree like enchantment system

But I figured it out

[hoary scarab]

Oh IDK if it exists in the minecraft code but it existed in spigot 1.8.8

MaterialData  md = b.getState().getData();
String blockType = (md instanceof Tree) ? ((Tree) md).getSpecies().toString() : ((Leaves) md).getSpecies().toString();
if(blockType != null) {
    switch(blockType) { 
    case "GENERIC": saplingtype = 0; break;
    case "REDWOOD": saplingtype = 1; break;
    case "BIRCH": saplingtype = 2; break;
    case "JUNGLE": saplingtype = 3; break;
    }
}

[dense galleon]

I mean I'm making a fabric mode anyway 😂 😅

[wheat carbon]

yapps they’re not talking about ingame trees

[dense galleon]

Oh

[bitter grove]

mans linked a minecraft tree

[dense galleon]

I didnt even

😂 😂 😂

I was kinda confused when he said Leaves

[hoary scarab]

Well it is a minecraft server xD

Java 14+ contains Tree | getKind(), accept(TreeVisitor<R,D> visitor, D data)
All I could find.

[dense galleon]

Alright I ended up making my own data type kinda

https://paste.helpch.at/uxakiwipet.cs

[sterile hinge]

That’s compiler stuff

Tree structures are often modeled implicitly

[dense galleon]

Though I got a question: How can iterate (depth first) through this?

[dense galleon]

            EnchNode[] sharpnessNodes = {
                new EnchNode(root, new EnchantmentInstance(Enchantments.SHARPNESS, 1)),
                new EnchNode(sharpnessNodes[0], new EnchantmentInstance(Enchantments.SHARPNESS, 2)),
                new EnchNode(sharpnessNodes[1], new EnchantmentInstance(Enchantments.SHARPNESS, 3)),
                new EnchNode(sharpnessNodes[2], new EnchantmentInstance(Enchantments.SHARPNESS, 4)),
                new EnchNode(sharpnessNodes[3], new EnchantmentInstance(Enchantments.SHARPNESS, 5))
            };``` 

Is there any way to have this snippet of code work

It's annoying to have to create a bunch of variables and store them to use later

[dense galleon]

Or something similar

[sterile hinge]

well just design it as actual tree structure

means an enchantment has n children

[dense galleon]

So create like an EnchTree class?

Which holds EnchNode instances?

Or I mean an array of those

[sterile hinge]

just embed it into your Enchantment type

no need for an explicit tree structure

[dense galleon]

Enchantment is a minecraft class

Can't really embed it in there

Or I mean I can, just not sure if it's really worth it

[sterile hinge]

yeah then you need a wrapper

[proud pebble]

what is this for?

[queen plank]

How do I use a particle without it flying away? I have a way to make shapes out of particles and am trying different particle effects. However, some particles (like flame) just fuqs off in mach 2.

[rigid mountain]

How can i remove all of the messages Mongo sends on connection?

[tacit belfry]

For some reason with maven whenever i do:

         <dependency>
            <groupId>org.spigotmc</groupId>
            <artifactId>spigot</artifactId>
            <version>1.18.2-R0.1-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>```
It doesn't work. The latest version it sees is 1.17

I understand that 1.18 changed the spigot api?

[dusky harness]

spigot = nms
make sure u ran buildtools

[tacit belfry]

yeah I want NMS

but wait why do I have to run buildtools if its getting it from a repo

[dusky harness]

its not

[tacit belfry]

oh

[dusky harness]

its getting from local maven repo

since you can't host the minecraft jar online (legally)

[tacit belfry]

oop ok

[past ibex]

codemc has an illegal repo

although it is illegal so you shouldn't add it to your repositories then use it so that others don't have to use buildtools to compile your plugin

[tacit belfry]

erm why is TPS hard coded..

[stuck hearth]

Likely the max it can be, makes sense it would be set at 20

[tacit belfry]

Is there any way to get the actual server TPS?

[hoary scarab]

Bukkit.getServer().spigot().getTPS() I think. But its better to calculate it yourself.

[tacit belfry]

How would I calculate it? Also this only works with paperspigot

[hoary scarab]

I don't use paper. And just have a runnable caching the times it runs and calculate if its within 50ms of each other

[tacit belfry]

Ok thanks

[tardy cosmos]

Does anyone know a better regex for converting spigot-style hex codes to #ffffff format? what I have works but it's pretty clunky

public static String decolorize(String string) {
    if (string == null || string.isEmpty())
        return string;
    return string.replace(ChatColor.COLOR_CHAR, '&').replaceAll("&x&([0-9A-Fa-f])&([0-9A-Fa-f])&([0-9A-Fa-f])&([0-9A-Fa-f])&([0-9A-Fa-f])&([0-9A-Fa-f])", "#$1$2$3$4$5$6");
}

I'm not exactly an expert with regex so I don't know if there's a better way to handle the matching groups. I know that &x(&[0-9A-Fa-f]){6} matches the spigot-style hex code properly but then I don't know of a way to transform it to the #ffffff format

[hoary scarab]

Aren't you able to just do ChatColor.STRIPCOLOR?

[tardy cosmos]

I'm trying to transform the color codes back to a readable format, not remove them entirely

otherwise yes that would have worked

[hoary scarab]

Ah. One sec then

[tardy cosmos]

Basically &x&a&b&c&d&e&f -> #abcdef

[hoary scarab]

Wait what gives you that? I use #ffffff for hex...

[tardy cosmos]

When you do ChatColor.of() and then toString() on it that's what it transforms into

sending that format in a raw string for a chat message sends it as a hex color code lol

it's also the format that gets sent with an item's getDisplayName() and getLore() which is what I'm trying to transform

[hoary scarab]

Hmmm... yeah IDK for that then...

[tardy cosmos]

I'll just move the regex to a static final string and call it a day

[hoary scarab]

Kinda odd it would format like that.

[tardy cosmos]

magic

[warm steppe]

you need gradle for that

[tardy cosmos]

no.. you don't?

[lyric gyro]

🤮 Have you looked into just using Kyori instead? I think you can make a builder to change it from weird hex format to more readable hex format

I used something like that before for a gradient chat plugin. I can send it over here when I get on

[tardy cosmos]

don't feel like using a massive messaging framework like that is necessary for only parsing this small situation, a fair suggestion though

[hoary scarab]

So IDK about using regex but you can probs loop through the chars

public String decolorHex(String string) {
    Set<String> hexCodes = new HashSet<>();
    for(int i = 0; i < string.getLength(); i++) {
        if(string.subString(i).equals("&") && string.subString(i+1).equals("x")) {
            hexCodes.add(string.subString(i, i+6))
            i = i+6;
        }
    }

    String edit = string;
    for(String code : hexCodes)
        edit = edit.replace(code, code.replace("&", ""))
    return edit;
}
```Pesudo code just wrote it up.

[dense drift]

You cant use a normal set for that though, you care about the order

[hoary scarab]

Not really as it loops through all retrieved codes.

[dense drift]

Ah, I read it wrong

[hoary scarab]

private Pattern mcFormattedHex = Pattern.compile("&x&([A-Fa-f0-9]){6}");
public String decolorHex(String s) {
    Matcher matcher = mcFormattedHex.matcher(s);
    return matcher.replaceAll(color -> color.replace("&", ""));
}
```This might work....

[dense drift]

Well you can still use a regex for that and remove the section symbol

[hoary scarab]

Ok finally got the pattern right.
Try this @tardy cosmos

String hexString = "&6Hex Colors | #ffa800H#ff9c00e#ff8f00x #ff8200C#ff7400o#ff6500l#ff5400o#ff4000r#ff2400s";

public String removeColor(String s) {
    return s.replace("§", "&");
}

private Pattern mcFormattedHex = Pattern.compile("&x([A-Fa-f0-9&]){12}");
public String decolorHex(String s) {
    Matcher matcher = mcFormattedHex.matcher(s);
    return matcher.replaceAll(color -> color.group().replaceAll("&", "").replaceFirst("x", "#"));
}

[tardy cosmos]

I guess that's sort of one way to get around the matcher groups, it would match for things like &x&&&&&&&&&&&& though which I guess isn't horrible but the solution I had for it now might just be easier to do at this point

[hoary scarab]

👍

[tardy cosmos]

Thanks for the attempts

[hoary scarab]

MinecraftServer.getServer().recentTps make sure that you type .recentTps and not .getRecentTPS().

cus i assumed there was a getter but there isnt.

this requires nms unless theres some other way to get it without requiring a certain version

[tacit belfry]

I just opted for that route, but I am using 1.18.2 Spigot and it says its deprecated 😬

for now its the best i could find, there might be a way to get the MinecraftServer instance through spigot but i dont know that way

Hey everyone!

I'm honestly really keen in learning how to code minecraft plugins. Do any of you have any suggestions on what sort of tutorials to learn from?

Like YT videos or anything honestly.

[hoary scarab]

?learn-java

[neat pier]

FAQ Answer:

Online Courses:
Online courses are also great for learning java. Some websites that offer them are:

• Coursera - Free unless you want a certificate
• PluralSight - Great courses from what I've seen. Mostly Paid
• Udemy - Never used them myself but they seem to all or at least most be paid.
  My first ever course was one from Coursera. - I can say it was pretty good at introducing me to the programming world as a whole not just java.

Oracle Docs:
Oracle docs can help a lot at learning and understanding java:

• Start with this,
• Breeze through this (skipping stuff that doesn't seem relevant like bitwise operators),
• Hit this.
  They're the first three from this larger thing which you should definitely go through overall. But those three should be enough for slightly better understanding of what is happening here without feeling like a huge time sink.
  That one is a small part of this larger site wherein "Essential Java Classes" and "Collections" also have good useful stuff

Other services:
Some other cool services that will help you learn java are:

• SoloLearn
• W3Schools
• JetBrains Academy

As you can see there are plenty of good ways to learn as long as you're willing to invest the time. Have fun learning!

[dense drift]

you can not force it

[haughty parrot]

What if you escape it

“\”hi\””

[lyric gyro]

it'll probably write '"hi"' lol

because it's part of the contents

[dense drift]

exactly

[icy shadow]

Look into ScalarStyle.SINGLE_QUOTED if you really wanna add / remove it

youll probablyu need to do some weird stuff though

[hoary scarab]

getConfig().setString("PATH", "A string");

[hoary scarab]

... all

[lyric gyro]

There is only set, there aren't setThing variants

[hoary scarab]

Ah yeap. Thought there was.

[lyric gyro]

that really sucks tho, but like, bleh

[hoary scarab]

Could try just adding .toString() to the value.

[icy shadow]

String#toString just returns this

To be precise, it's an identity function

Hey guys im having issues with bungee brigadier

can anyone help a bit?

I'm trying to do a clientside glowing effect with PacketPlayOutEntityMetadata but i haven't worked with that packet in a while and am unsure what stuff to mess with.

Could anyone help?

How do you set a custom variables value in custom event from a listener

My event

I'm trying to set the droppedAmount from a listener

[proud pebble]

this isnt thte channel for that, your probably looking for somethng like either #970433902772617246 or #970433904517464134

if i would create a command /Test in my lobby, is it possible to execute something on a other server connected to the bungeecord?

[broken elbow]

not directly from the lobby. you'd either need a plugin on the other server and a plugin on your proxy to relay the information or some other way to relay the information to the plugin on the other server

[wintry grove]

how do I apply a gradle plugin to other subprojects in kotlin DSL?

[shell moon]

best way to save items in mysql? (like player inventory, or backpacks, etc)

[dusty frost]

Paper binary serialization

[shell moon]

and with spigot?

[lyric gyro]

cry

[dusty frost]

copy the Paper binary serialization method? lmao

[shell moon]

how exactly would that work?

if i want to save a backpack for example

respecting empty slots

[dusty frost]

    public static ArrayList<byte[]> serializeInventory(Inventory inventory) {
        var bytes = new ArrayList<byte[]>();

        for (ItemStack itemStack : inventory.getContents()) {
            if (itemStack == null) {
                bytes.add(null);
                continue;
            }
            bytes.add(itemStack.serializeAsBytes());
        }

        return bytes;
    }

    public static ArrayList<ItemStack> deserializeInventory(ArrayList<byte[]> inventory) {
        ArrayList<ItemStack> inventoryHolder = new ArrayList<>();

        for (byte[] itemStack : inventory) {
            if (itemStack == null) {
                inventoryHolder.add(null);
                continue;
            }
            inventoryHolder.add(ItemStack.deserializeBytes(itemStack));
        }

        return inventoryHolder;
    }

these are my methods for serializing and deserializing an inventory

[lyric gyro]

null

[dusty frost]

yeah spigot really gotta do us dirty likc that

[lyric gyro]

it's funny because minecraft doesn't use null items at all

and by funny i mean unfunny

[shell moon]

thats available on paper since 1.15 only right?

[dusty frost]

no clue, but use latest and Paper

you'll be much happier for it

https://i.imgur.com/Y7Q6GHO.png

[shell moon]

yeah, i tend to support 1.8 too

[dusty frost]

😉

[shell moon]

and spigot too

[dusty frost]

oh yikes

7% ain't look too good

[lyric gyro]

not even i hate myself that much dude

[shell moon]

another alternative?

[dusty frost]

stop developing plugins for a version of minecraft that is 6 years, 9 months, and 22 days old?

and only represents 7% of the market share

[shell moon]

mmm not enough

any alternatives?

[dusty frost]

have fun lol

[pine flax]

lucko helper has some item serialization/deserialization stuff, not sure if it'd work on 1.8 https://github.com/lucko/helper/blob/master/helper/src/main/java/me/lucko/helper/serialize/InventorySerialization.java

[shell moon]

weird, i use a similar thing for backpacks in other plugin

was expecting something different, but i guess is the only one approach

thanks, wonder how long would a deserialized inv is

hope it fits in a db column

[lyric gyro]

well it's definitely not the only approach lol

it's your only approach

[shell moon]

for spigot and 1.8+?

[dusty frost]

those are choices you made :)

[shell moon]

yeah, and thats prob the only approach to achieve that

[dusty frost]

funnily enough, even your own plugins would still benefit greatly from not supporting 1.8

[stuck hearth]

Counter argument, 1.8 just have less bstats diversity

[dusty frost]

wtf is "bstats diversity"

[cerulean birch]

so i need to get all the blocks between a player, and 10 blocks in the direction that the player is looking

the player.rayTraceBlocks doesn't really do what I need b/c it just returns the position where it ends, player.getTargetBlock doesn't really suffice either

any recommendations?

edit: gonna try player.getLineOfSight()

[dusty frost]

Sounds like you're looking for a BlockIterator! It does ray tracing and iterates along blocks in a line, which sounds like exactly what you need!

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/util/BlockIterator.html

[cerulean birch]

this does indeed sound like exactly I need, I'll take a look at it and try it out, thanks!

[winged pebble]

LivingEntity#getLineOfSight(Set<Material>, int) also seems applicable

[cerulean birch]

It's what I considered at first, but I want it to go through blocks and go the full distance rather than stop at the first target block

[winged pebble]

It doesn't appear to stop at the first block, it goes the distance you pass in, no?

[stuck hearth]

I meant it as a joke, but the likely hood the server has a plugin that would even show bstats its there.

[dusty frost]

I mean, we gotta draw the line somewhere

[cerulean birch]

"all blocks from the living entity's eye position to target inclusive" not sure

my workaround was passing in a hashset containing all materials as the "transparent blocks" argument but ehh

[dusty frost]

We have these metrics, and this guy has bstats on his actual plugins lol

[stuck hearth]

yea

[rugged bane]

I think for free plug-ins, I wouldn’t put the effort in to support 1.8, unless it required no extra time or effort.

However, with paid / commercial stuff, I can see the benefit supporting older versions. Naturally, you want to take as much market share as possible

[sterile hinge]

I doubt you‘d earn enough from 1.8 to cover the extra work you need to put in to make it work (heavily depending on what the plugin does obviously)

[dusty frost]

yeah the cost-to-benefit ratio is rarely in favor of 1.8 these days, especially with dwindling market share at currently 7%

[rugged bane]

Yeah I think it depends on what it does, some stuff is easier than others

That’s crazy how it’s now only 7% though

That’s dropped so quickly

[warm steppe]

Why would this:

@Path("list")
public static final Property<Map<Integer, Map<String, Object>>> CHAMP = Property.create(
        Map.of(
                1, Map.of(
                        "name", "test1",
                        "name_variations", List.of("tt", "aa"),
                        "skin_urls", List.of("tt", "aa")
                ),
                2, Map.of(
                        "name", "test2",
                        "name_variations", List.of("tt", "aa"),
                        "skin_urls", List.of("tt", "aa")
                )
        )
);

throw: class java.lang.Integer cannot be cast to class java.lang.String?

[dense drift]

How does your config look like?

Also, an object would help a lot

[dusty frost]

that is a hell of a generic type specification lmao

[hoary scarab]

It depends on the plugin type too. Which game mode the plugin is mostly used by etc...

For example with my minions plugin it's more beneficial on skyblock but it's also used in prison, factions, survival and I think atleast one towny server.

I don't have the plugin checking stats but users that have requested support usually run the following versions.

Skyblock - 65% 1.8, 25% 1.12, 10% latest.
Factions - 80% 1.8, 15% 1.12, 5% latest.
Survival - 90% latest, 2% 1.8, 5% 1.12, 3% 1.13 - 1.18

It goes on from there. Majority of users of my plugin use skyblock though so even with my newer minions plugin it was beneficial to add backwards compatability.

I will try a fix, aka making a list of items I want to remove from gensLocations and removing them all afterwards

[hoary scarab]

java.util.ConcurrentModificationException: null
Caused when you are either modifying a object while looping through it. (Use an iterator)
Or when 2 threads are editing the same object. (Use concurrent objects)

[worn jasper]

yup, that's what I found on stackoverflow

thanks anyways!

[viral moth]

heres a suggestion, iterating through the list of all generators will not take a lot of time, it is dropping the items via bukkit that takes time. idk if you are even dropping the items since acidgens now just puts it in a storage thing but regardless you dont want to do that stuff async. If you are actually dropping the item, i made a thing to optimize thatwhich would be perfect for you use case, lmk if you want it

[worn jasper]

uh, the dropping is sync, you can't drop items async

[viral moth]

ik, youre running stuff async, thats why that error was thrown

im saying that you shouldnt do it async, even if it is just looping through the generators

actually

[worn jasper]

uh I already fixed that issue

it had nothing to do with that

lol

[viral moth]

wack

ight lol

[worn jasper]

as I said previously, the issue was that I was looping through a list and modifying it, so I created a list with everything I wanted to remove from the other, and only removed everything afterwards

if that makes any sense

xd

[broken elbow]

I want to see what this is

[viral moth]

yk what

that would cause it

[broken elbow]

can you send code here?

[viral moth]

sure, 2 sec

i plan to improve it further but this was something i made in like 10m

[worn jasper]

my bet is that you are limiting how many items can be dropped/spawned per tick

idk

lol

[viral moth]

  public static int STACK_DISTANCE = 9;
  public static int MAX_STACK_SIZE = 64;

    public static void spawnItem(ItemStack i, Location loc, UUID owner) {
        ItemStack item = i.clone();
        for (Item _item : loc.getNearbyEntitiesByType(Item.class, STACK_DISTANCE)) {
            ItemStack itemStack = _item.getItemStack();
            if (itemStack.getAmount() >= MAX_STACK_SIZE) continue;
            ItemStack _itemStack = itemStack.clone();
            _itemStack.setAmount(item.getAmount());
            if (_itemStack.equals(item)) {
                int amountToStack = Math.min(MAX_STACK_SIZE - itemStack.getAmount(), item.getAmount());
                itemStack.setAmount(itemStack.getAmount() + amountToStack);
                item.setAmount(item.getAmount() - amountToStack);
                if (item.getAmount() <= 0) return;
            }
        }
        loc.getWorld().dropItem(loc, item);
    }```

no

just check if another item is near it and add to that item's count

avoids spawning an extra item entirely

[worn jasper]

never thought about that.

[viral moth]

i plan to make my own stacker that goes past 64 however i havent had time to work on this project

[worn jasper]

they will stack anyways, but that avoids spawning another item at all

ye

[viral moth]

but it avoids spawning extra items which is that most expensive part

[worn jasper]

ye

although in acidgens like you said, that wouldn't be an issue

since it's mostly everything digital

xd

[viral moth]

yeah, however i dont think that the item spawning was the issue tbh

[worn jasper]

but I will keep that in mind to use next time.

[worn jasper]

nha it wasn't

but it's still a good tip

[viral moth]

idk why he removed it

[worn jasper]

I mean, the issue was he was using skript

[viral moth]

yeah lol

[worn jasper]

😂

[viral moth]

i told him a long time ago

but spawning items makes kids feel like they are making more progress so removing it makes it feel more boring imo

[worn jasper]

this is going a bit offtopic btw

[viral moth]

you right

[shell moon]

when server is stopped, players are kicked before onDisable is called?

[broken elbow]

yeah

bcz spigot

(I Think. idk I always blame spigot lol)

but they are kicked before

[warm steppe]

They are.

[shell moon]

mmm, so basically PlayerQuitEvent is called for each player online

when server stops

how to know in there if server is being stopped?

[warm steppe]

uhh

[shell moon]

plugin.isEnabled ?

or something

[broken elbow]

nah

the plugin will be enabled

what's the xy here tho?

what exactly are you trying to do and why

[warm steppe]

https://www.spigotmc.org/threads/execute-a-code-when-shutting-down-or-restarting-the-server.316096/#post-2981061

piggy's answer

[broken elbow]

ugh they clearly want to execute something on players. so don't think that will actually help

[shell moon]

data is saved on inventory close event, ofc async, but on server stop you cant (iirc) create tasks, so i wanna know how to "recognize" if server is topping to not use async, but sync

[broken elbow]

unless shut down hooks are called before players are kicked idk

[warm steppe]

just save it on player quit event

save it to a list or smth

[broken elbow]

pretty sure the server waits for async tasks to complete? unless I'm misremembering and its the other way around

[warm steppe]

and then save it all somewhere when onDisable()

[broken elbow]

nitro what are you talking about? xD

[shell moon]

idk either xd

[warm steppe]

he wants to save data

wdym

[broken elbow]

he knows how to save data lol

[shell moon]

xd

[broken elbow]

did you read their messages?

or the entire message

[warm steppe]

yeah but you can save data when player quits

[broken elbow]

rather

[shell moon]

i dont think so xd

why would i use player quit event

im not even listening to it

[broken elbow]

yeah. but the problem is that possibly spigot won't wait for async tasks

when the server is shutting down

[shell moon]

blitz you get the question right?

[broken elbow]

yeah

[warm steppe]

try it?

[broken elbow]

try what lol?

[warm steppe]

does it wait for them to complete

[shell moon]

so, to prevent dups, what would be the best way if i only save data on inventory close event (ofc certain inventories)

[shell moon]

first of all, players are kicked before onDisable is called

[broken elbow]

ah yeah. the server won't wait for the async tasks to complete. or maybe it will but throw a warning. I Know it throws the warning just don't remember if it will wait or not

[shell moon]

correct? ☝️

[broken elbow]

yeah

that is correct

[shell moon]

if so, that means inventory close event and player quit even is thrown for all players

and then onDisable is called, correct?

that means in onDisable, getOnlinePlayers().length will always be 0 right?

[broken elbow]

not sure actually. maybe. idk if inventory close is called but I'd assume so. you can try tho

[broken elbow]

pretty sure yeah

[shell moon]

so, if i wanna decide between using async (as usual when inventory closes) or sync (so server waits until database is saved)

how would i check that?

there was a serverIsStopping or sth? xd

[viral moth]

if i had to guess the server kicks the players after all plugin's are disabled

however i would just test it myself if i were you

[broken elbow]

so yeah @shell moon some googling says that the players get kicked after the plugins are disabled

so I guess I Was wrong

but yeah. test it

just to make sure

[shell moon]

so basically, all plugins that listen to player quit event to save data

breaks? xd

[broken elbow]

nah

[shell moon]

if plugin is disabled, how would they work?

[broken elbow]

idk

I do know that they're kicked 1 tick before the event is called

which is stupid

or something like that. I had problems with FrozenJoin

unless again I'm misremembering

but anyways if you try, I guess you'll find out the answers

[shell moon]

i'll quickly debug the events

this driving me crazy

jlink 🥺

[dusky harness]

note that it still needs the JRE to be installed

either that or u need to make it an installer

[lyric gyro]

no?

the entire point of jlink is to ship a whole runtime image with your application so the jre doesn't need to be installed

[dusky harness]

oh idk about jlink but launch4j requires the JRE iirc

or installer

either that or i never found a way of how to include the runtime image

I have a biome provider, and when I set a biome to deep ocean, it sets it in f3, but still generates land there. The land has shipwrecks and ocean monuments on it, yet no water.

[past ibex]

That's how 1.18 generation works

Biome is determined by continentalness, weirdness, humidity, and temperature noise

the same noise also does world heights and terrain generation

setting only biomes does not change terrain generation like it did pre-1.18

Question, so im making a game system and saving it to mongo via GSON, but i keep getting these circular refrencing issues. I swear I have looked over and looked over the code several times and cannot find it. I have even commented out sections to trace where it is coming from. One save it works fine and then the next one it does not. Here are my full classes:

yes

it's probably trying to serialize the BukkitTask as well, you could try marking it as transient

[dark garnet]

how can i convert a long milliseconds to this: X.YY
X = seconds
YY = 2 decimal places of milliseconds
not sure if im explaining this well enough lmao

[dusky harness]

long milliseconds = 12345L;
double seconds = Math.round((double) milliseconds / 10.0) / 100.0;

there's also: ```java
private static DecimalFormat FORMAT = new DecimalFormat("#.##"); // constant

long milliseconds = 12345L;
String seconds = FORMAT.format((double) milliseconds / 1000.0);

[dark garnet]

yea i tried the decimalformat thing

i think i had just done it wrong

[surreal lynx]

What's the best way to delay something by a second or so?

[dark garnet]

bukkit runnable, runtasklater

[surreal lynx]

Ok, thank you

Is that the only way though?

Or is there an alternative

[dusky harness]

well

[dark garnet]

probably but bukkitrunnable is the easiest i think

[dusky harness]

in java itself there is an alternative (outside of bukkit)

but I'd recommend using runTaskLater

[hoary scarab]

Can make your own delayed tasks.

            // your code
            countDown = 60;
            //cancel task unless you want it to repeat.
        }
    });
}

Hey i wannas k

[dark garnet]

neither of these worked for me, the first one just displayed 0.01 and the second one displayed 0

final long timeLeft = TimeUnit.MILLISECONDS.toSeconds(timer.get(tnt) - System.currentTimeMillis());
final BukkitRunnable runnable = new BukkitRunnable() {
    public void run() {
        tnt.setCustomName(ChatColor.RED + "" + ChatColor.BOLD + Math.round(timeLeft / 10.0) / 100.0);
    }
};
runnable.runTaskTimer(Main.plugin, 0, 20);```

[dusky harness]

well you're using TimeUnit to convert to seconds

but the issue is that it returns a long

[dark garnet]

oh right

[dusky harness]

not a double

just use ```java
double seconds = Math.round((double) milliseconds / 10.0) / 100.0;

[winged pebble]

You also need to move the calculation inside of run, no?

If you want it to update

[dusky harness]

oh that too

🥲

[dark garnet]

alright

just realized i cant have the period of the runnable set to 20 lmao

or else the milliseconds part is just useless

[dusky harness]

oh wait yea bc thats every second

🥴

[dark garnet]

lmfao

hmmm now how do i solve this: https://srnyx.has.rocks/java_TGWjAKwA4J.mp4

the flashing

[dusky harness]

I'd just do #.#

instead of #.##

not sure if there's another fix

wait

no thats bc it's switching

try this:

[dark garnet]

unrelated, how would i change how many decimals are shown using this method:
Math.round((timer.get(tnt) - System.currentTimeMillis()) / 10.0) / 100.0

the / 10.0 part?

o wait it would be both divisions right

so if i just wanted #.# i'd do Math.round(timer.get(tnt) - System.currentTimeMillis()) / 10.0

[dusky harness]

String seconds = String.valueOf(Math.round((double) milliseconds / 10.0) / 100.0);
if (seconds.split("\\.")[1].length() == 1) {
    seconds = seconds + "0"; // if the amount of chars after . is 1, then add an extra 0 after
}

[dusky harness]

uhhh not sure, i gtg rn sorry

[dark garnet]

alright ill experiment, thank you!

[viral moth]

use BigDecimal.valueOf(0.5).format("#.##"); that will give you 0.50

my syntax/method names might be a little off as i barely use it but that is exactly what you want

[trail burrow]

need help on how to get updated code to the original developer github? My github never seems to work using github desktop

[hushed badge]

make a pull request? I'm unsure as to what ur asking here

[vestal talon]

fetch origin

[trail burrow]

pull request, I just want to send some updated code, I can't seem to figure out how to do it. I can't even update my own github with my setup. It broke I believe when I attempted to do it from two different locations

[topaz gust]

You would need to commit and push the “updated” to the git then pull from it wherever else you want it (or whoever)

[somber gale]

Does someone know if Gson will also use any fields defined in an inherited Interface?
Like when I have this:

public class SomeClass implements SomeInterface {
    public String message;

    private static interface SomeInterface {
        boolean error;
    }
}

And the JSON I parse is {"error": true, "message": "Message here"}, would Gson use the error field from the interface or is that completely ignored?

From what I tested now does it seem to not work as boolean error; is treated as a final entry

[sterile hinge]

Interfaces don’t have instance fields

[icy shadow]

wtf that is evil

[broken elbow]

everything is

[lyric gyro]

How can i get the location
when the table is like PreparedStatement ps = mySQL.getConnection().prepareStatement ("CREATE TABLE Spawn (" + "ID INT NOT NULL," + "X DOUBLE NULL," + "Y DOUBLE NULL," + "Z DOUBLE NULL," + "YAW FLOAT NULL," + "PITCH FLOAT NULL," + "WorldName VARCHAR(255) NULL," + "PlayerName VARCHAR(255) NULL," + "PlayerUUID VARCHAR(255) NULL," + "Server VARCHAR(255) NULL," + "PRIMARY KEY (ID))");

[rugged bane]

Wdym get the location

Read from the DB, pass it as an object

[lyric gyro]

so i can get the location now but my count down just doesnt work please let me know how i could fix it https://paste.helpch.at/qibobijece.java

[broken elbow]

what does "doesn't work" mean? what's the expected output and what's the actual result you get?

[lyric gyro]

So what happens is i do /sp i have to type it 5 times instead of doing a count down then it goes in to the minus so it does reset

it is currently doing this https://prnt.sc/hQy5kOZmRTxR

when i type the command so im trying too figure where my code is wrong

as it doing it on the amount of time i type the command in

[warm steppe]

what the fuck is that formatting

[lyric gyro]

its so ik what block is what

[broken elbow]

c# lol

[warm steppe]

😫

also

[broken elbow]

its called Allman or whatever

[lyric gyro]

lol

[warm steppe]

so K&R is the only usable style

[lyric gyro]

what the fuck is gnu and horstmann

im off back to try fix my timer 🙂

[broken elbow]

fairly certain runTask, only runs the task once

what you want to use is runTaskTimer

[lyric gyro]

It runs one once per command is done

but i can try run TaskTimer

What would period be ?

[broken elbow]

well its in ticks

so 20

for 1 second

[lyric gyro]

and delay is that going to be 1 Tick aswel ?

[broken elbow]

well you want that 20 as well

its in ticks yeah

[lyric gyro]

okay ill test that see if that fixes my issue

[broken elbow]

also are you accessing the database every time the command is ran?

that sounds like a nice server crash feature xD

[lyric gyro]

For some reason i have to type my command 5 Times for it too take me to spawn instead of 5 seconds

[broken elbow]

even after changing it to runTaskTimer?

can you send your current code?

[lyric gyro]

yh

here ya go v

https://paste.helpch.at/mopidixuli.java

[broken elbow]

you only updated it for the command when it uses an argument

when you do /spawn it will still just execute runTask

[lyric gyro]

ahh i didnt save it then

ill re finish that

just gotta fix an ACF problem that idk how to fix

[broken elbow]

maybe we can help?

[lyric gyro]

https://paste.helpch.at/etujiziruz.sql

Thats the error i have recieved

[broken elbow]

you need to shade ACF

[lyric gyro]

i have

[broken elbow]

are you minimizing?

[lyric gyro]

i am not

[broken elbow]

check your jar. open it with winrar or JDGUI or something

to make sure its there

[lyric gyro]

im just rebuilding i think i have it now ima give it a quick test

issue was resolved it was just a broken bit of code

How can i cancel a task correctly

as my cancel isnt working correctly

but you did fix my other issue thanks Blitz

[broken elbow]

you should be able to cancel the task from within itself. if not you might have to save the task in a variable and cancel it from there

[lyric gyro]

I’ve got the cancel writhing it sled but it ignores it

So I’m gonna have too turn it into a variable

[dusty frost]

OTB gang

K&R still does Allman for function blocks iirc

One True Brace always puts the opening brace on the same line

[rugged bane]

Which is the style where you do
function
{

}

[dusty frost]

Allman

it's awful

[icy shadow]

allman is great

[pulsar ferry]

Bad tastes

[lyric gyro]

from now on i'll use a mixture of Whitesmiths and GNU styles

void foo ()
        {
        bar ();
        baz ();
        }

[rugged bane]

I’ve started using Allman more

I prefer it because easier to see where the brackets are

Vs having it on the same line as functions

[dusty frost]

it's just so much extra whitespace, and if you're using an IDE based on IntelliJ at least, it shows you indents and things really nicely, plus I use rainbow brackets so it makes matching brackets the same color, very nice to use

[rugged bane]

Yeah, I think for me it’s more for visuals, like sometimes I’ll visit code on GitHub if I don’t want to pull it locally just to check something

[dusty frost]

hmm, I never really had a problem distinguishing where functions start and stuff, maybe it's more of a PHP thing?

but honestly, PascalCase and Allman indentation are the biggest reasons I don't like C#/anything .NET

[rugged bane]

I mainly started adopting the style since I primarily using PHP, so could be.

I never saw the appeal of the style before, but then started using, and I find it more readable

But naturally all this stuff is preference based

[dusty frost]

yeah, yeah, I suppose it's just what you're used to

like I managed to use C# and stuff for a few things for my class, didn't really end up liking it that much

the biggest appeal is just the raw features it has over Java, and the integration with like F#

[rugged bane]

I do find it crazy how much languages overlap

When I first started programming and heard “once you know one, the others are a bit easier” I thought that was full of crap

But so true

[dusty frost]

the others are a lot easier lol

at least, languages in a similar area, like OOP langs

I know Java really well, and I can effectively use Ruby, C#, Python, C++, C, Kotlin, JavaScript, Go, PHP, Swift, etc. very quickly

just by looking up the syntactic differences and stuff

now languages like F#, Clojure, and Haskell, etc. are a bit harder to learn because they are fundamentally different lol

[lyric gyro]

clj

[icy shadow]

all imperative languages are just reskins of each other

[rugged bane]

Yeah it’s crazy, I think if I were to learn any, Go would be the one to spark me

[icy shadow]

Also, close your PreparedStatements and ResultSets

Else, it will create memory leaks

okay will do

its all been fixed ive recoded it and used a switch statement in stead of an if statement

how can i like disable a command from being used?
i wanna make it so no one (including operators) can use /ban-ip

ping if reply

What's a good video to start on creating plugins myself?

Would this work for closing it public boolean checkTableExists() { try { PreparedStatement ps = coreDatabase.getConnection().prepareStatement("USE Spawn;"); ps.executeUpdate(); DatabaseMetaData dmd = coreDatabase.getConnection().getMetaData(); ResultSet res = dmd.getTables(null, null, "Spawn", null); if (res.next()) { ps.close(); res.close(); return true; } ps.close(); res.close(); } catch (SQLException e) { throw new RuntimeException(e); } return false; }

i couldnt remember if it was in the if statement or outside of it

[teal rapids]

How do y all understand coding? It's like how do you know where to put semi colin, or where to put the dashes and brackets? Can someone explain?

Please I wanna make my own plugins because I can't find what I want.

[torpid raft]

how do you understand how to write a paragraph? Where do you put nouns or verbs or adjectives? When do you use periods and when do you use commas?

both are just a set of syntax rules, and coding even arguably has a much much simpler set of rules than english does

A simple way to begin getting used to reading and writing java is to google around for a java tutorial, and visit any one of the hundreds of relevant sites - it honestly does not matter which

download a java IDE like IntelliJ / Eclipse / Whatever, and recreate the examples provided in that tutorial

from there the world is your oyster

[teal rapids]

English is way easier btw

More people know English than coding

But how long does it take to get used to coding, like to not look at a sheet woth the place holders and stuff

[lyric gyro]

English is easy only because you know it already

It's actually shit

[topaz elm]

few months

for the basics probably a month

but you never stop learning

[warm steppe]

my dad is almost 60, he has never learned english, never had contact with it, yet he can make some sentences and talk a bit, just by watching some videos on youtube for 2 months

[dusty frost]

yeah the syntax rules of programming languages are much more strict, enforced by a compiler that will make 100% sure, and you can use nice IDEs that will give you generally exact problem spots

like in Java, basically every line that doesn't have a {} on it will end in a ;, and for and if are always followed by the expression in ()

[past ibex]

Syntax is easier than logic

[torpid raft]

it heavily depends on how much effort you put into trying to genuinely understand what's going on, as well as just your natural affinity for logic and problem solving

as far as just memorizing what the keywords mean, it generally doesn't take too long as long as you try using them on your own instead of only following tutorials that spoonfeed you

When I took my first programming class in high school, most of the class had a great grasp on the basic java syntax less than halfway into the school year, and that was only with a 45 minute period every weekday + a bit of homework

[fresh spade]

Anyone have any idea why this isn't working? I'm trying to disable dyeing of a leather armor

@EventHandler
public void onLeatherArmorCraft(PrepareItemCraftEvent  e) {
        if(e.getRecipe() == null)
            return;
        
        if(e.getRecipe().getResult().getType() == Material.LEATHER_HELMET ||
                e.getRecipe().getResult().getType() == Material.LEATHER_CHESTPLATE ||
                e.getRecipe().getResult().getType() == Material.LEATHER_LEGGINGS ||
                e.getRecipe().getResult().getType() == Material.LEATHER_BOOTS) {
e.getRecipe().getResult().setType(Material.AIR);
        }
    }

[tight junco]

isnt the event cancellable

no uh

I think you might want to try CraftItemEvent?

[lyric gyro]

How can i change it from player.getLocation().getWorld().toString() to normal getWorld again

[hoary scarab]

Well... you can create a variable of the world
World w = player.getWorld();
Or if you really need to use the name you can use
Bukkit.getWorld(<name>)

[lyric gyro]

Thanks I did the bukkoit.getworld

[lyric gyro]

So im currently expirencing this https://paste.helpch.at/uhasagosuc.sql

And it says its inside here https://paste.helpch.at/jiyasizahe.cpp

[proud pebble]

if that did work then it would also prevent crafting of leather armor completely.

[fresh spade]

oh yes ur right!

thank you for finding that out, I wasn't thinking about that at all

[proud pebble]

when you say it doesnt work, what doesnt work?

id recommend that you put bukkit.getLogger.info(e.getRecipe().getResult().getType());
before your if leather armor statement so you can check if its coming back any type
and also a bukkit.getLogger just before the null check aswell.

basically just put some debug outputs to check your logic to see if its doing what you intend

if you get no messages then check that the event is registered.

[fresh spade]

Don't worry I already fixed it just forgot I sent a message here xD

And yes, I'm always placing some kind of debug outputs when I'm texting my logic

[candid arch]

Hi there is it possible to :

Create a HashMap<String, Object>, (Every Value is a class that extends the Object), putting content inside...
Find the good Value with a String key
Instantiate it with a parameter

I don't want to use Switchcase, this is good for a limited amount of options.
https://pastebin.com/9JEgncbE

(Maybe what i'm asking is unclear or maybe there's a better way to do so)

[lyric gyro]

Anyone know why Hikari Wont check if a table exists or create a table

i can send the class it just goes too an SQL Error

[leaden sinew]

It looks like you might want to do something like Map<String, Function<Territory, Objective>>?

Where the function gives the instance of the class

[candid arch]

Not really, sorry if I am not understandable. I want to create a map of objectives (every objectives extends Objective but are not instantiated yet).

Then, when devs use my API, they can add their own objectives in the list. (They add possibilities)

Finally, my plugin calls a function that will use a String to find an Objective in the map. If found, I want to instantiate the found Objective, with a parameter.

Something that already work on my plugin is this.

                Objective objective = null;
                if (objectiveType.equalsIgnoreCase("KOTH")) {
                    objective = new KingOfTheHill(territory);
                    objective.start();
                } else if (objectiveType.equalsIgnoreCase("STRUGGLE")) {
                    objective = new Struggle(territory);
                    objective.start();
                } else if (objectiveType.equalsIgnoreCase("CONTROL")) {
                    objective = new ControlPoint(territory);
                    objective.start();
                }

But since it is a if/elseif statement (switchcase too), it has limited optionsa dn will not include the objectives created by other devs with the API.

[lyric gyro]

too many caps

[night ice]

create table if not exists ....

[topaz elm]

switch(objectiveType)

[leaden sinew]

If you do it like I said, people who use the API can also call other methods when their object is instantiated which could be useful

[lyric gyro]

Yeah ive done that for it even existed tbf

[leaden sinew]

That still requires all objectives to be known ahead of time

[topaz elm]

ah

just smack em all into a list and do List#contains(objectiveType)

[candid arch]

I think I understand, like this I can even remove the map/list.

Every plugins hooked to mine will just check if the String correspond. if yes, they instantiate, etc. Else,nothing will happen. That's it ?

[leaden sinew]

Yeah

[leaden sinew]

What would that do?

[leaden sinew]

I would keep the map though

[topaz elm]

all ur doing is checking if the objective is equal to some constants

so you can just smack the constants in a list and make the list changeable at runtime

[leaden sinew]

No they need to create a new instance of the objective

[topaz elm]

ahh

just make a Map<String, Class<? extends Objective>>

[candid arch]

The map can be useful but in that case, it is not necessary. I'll keep it in, it can be useful sometimes.

Thanks ! ^^

[leaden sinew]

No problem

I would like to see how you do it without a map, so if you could send it again and ping me I would appreciate it

[candid arch]

aight

[candid arch]

It works too

[torpid raft]

seems like you're doing something silly with your database connections

[lyric gyro]

idk what you mean

its just a basic setup

[torpid raft]

no you're right your code is perfectly fine and the server just hates you and that's why it's crashing

jk

[lyric gyro]

haha

[torpid raft]

the error you are getting is a result of the main thread being locked up for a long time

and the server thinking it died

[lyric gyro]

how would i go about fix that

[neon wren]

your error is with your core database class.

Caused by: java.sql.SQLTransientConnectionException: HikariPool-1 - Connection is not available, request timed out after 30001ms.
        at com.zaxxer.hikari.pool.HikariPool.createTimeoutException(HikariPool.java:696) ~[Core-0.0.0-DEV.jar:?]

        ... 11 more

This means that your database isn't obtaining connection within 30 seconds (the default connection timeout period).

This also means that the network latency, or some of the queries are taking over 30 seconds to execute.

[torpid raft]

chances are you misconfigured your database address ~~/ credentials ~~^

[neon wren]

To help solve this problem, increase your maximum connection timeout to the hikari config.

It also could be a connection limit to the database.

Could you possibly provide whether the database server location is near the server's location? and also attempt what Ivan mentioned.

[torpid raft]

i've never heard of a server that has a latency of over 30 seconds x.x

[lyric gyro]

Ilbut it will do /spawn the first time and fail on the seconds so it can’t be a creds issue S it can set them as well

[torpid raft]

does your /spawn command rely on the sql database at all

if it doesn't it's possible that it never makes the connection in the first place but you just don't notice until later

[lyric gyro]

They are both in the exact same rack

[neon wren]

Is there a reason why you are selecting positions individually?

It makes no sense to do 5 selects for one location.

[lyric gyro]

It’s just massive get to get the location

It does it for multiple position across 3 servers

I’ve just been testing

[neon wren]

I'm not sure why you are searching over a server and world name, when it should be the id, as your PRIMARY KEY is the ID.

[lyric gyro]

How would I get the id tho from the database ?

[torpid raft]

kieran

[lyric gyro]

Yh

[torpid raft]

i didnt realize because i didnt see you posted your code but

[neon wren]

I don't understand why you are storing player names with the location either.

[torpid raft]

your issue is almost certainly this

coreDatabase.getConnection().prepareStatement("...");

[lyric gyro]

Yh I posted everything need to help fix it

[torpid raft]

you are never closing the connection from the thread pool

[lyric gyro]

How would I close it

[torpid raft]

by calling close on it lol

[lyric gyro]

Anywhere specific

[neon wren]

You shouldn't close the connection every time.

[torpid raft]

you should

that's how thread pools work

[neon wren]

If you are closing the data source connection, you throw away any benefit a connection pool has.

[torpid raft]

everywhere you have

coreDatabase.getConnection().{...}

make it

Connection conn = coreDatabase.getConnection();
conn.{...};
//other stuff here
conn.close();

[lyric gyro]

twr

[torpid raft]

no

first link about it on google

[lyric gyro]

you keep a single data source, and then use and close each connection/statement/resultset/etc

[torpid raft]

^

[lyric gyro]

hikari is smart

So too close it would i do something like

    {
        Connection connection = dataSource.getConnection();
        connection.close();
    }```

and call that too each of them ?

[torpid raft]

not quite

use them as you have been but instead of doing it all in one line like

coreDatabase.getConnection().prepareStatement("...");

save the Connection to it's own variable

get a prepared statement from it and proceed like usual

then after you are done with that query call close() on the connection

[neon wren]

Here's two examples for you @lyric gyro if you still haven't figured it out.

Here's a simplistic example for one of your methods that checks if it exists for a player.
https://paste.helpch.at/ipujofoceh.java

I'd recommend using try with resources, because you do not need to worry about closing anything.
https://paste.helpch.at/jugowowigu.java

I didn't change COUNT(*) back to *, so you'll need to do that, or switch it to where it'll get the amount from COUNT(*) and check if amount > 0.

I recommend possibly passing just the world name of the player, and not the entire player object.

[lyric gyro]

With this how does it know what database too get from ?

[dark garnet]

why is command returning null?
PluginCommand command = Bukkit.getPluginCommand("bipreload");

[cerulean birch]

did you register it in plugin.yml?

[dark garnet]

[cerulean birch]

[neon wren]

well you change dataSource with where you'd get the connection from?

that's a placeholder.

[lyric gyro]

okay np

Thanks ill give it a try and see if that fixes my issue ill let you know

[shell moon]

When using

Creeper c = world.spawn(loc,Creeper.class);
//Everything here runs after CreatureSpawnEvent was called and modified by other plugins in all priorities?
//Or it has a delay?

[dense drift]

Does that method even call the event?

[topaz elm]

try it and see

@lyric gyro anyways. Discord gave you some backup codes when you enabled 2FA. If you don't have those, there's no way to recover your account. That's most likely what they'll tell you as well

[lyric gyro]

Well, its gone then,😣 thanks for your help 💖

[lyric gyro]

So currently i have an issue where when i do the spawn command the first time it tps me too spawn if i wait 5 minutes then do it again it pulls this
Error: https://paste.helpch.at/varevagoca.md
CoreDatabase: https://paste.helpch.at/gocefusofe.cpp
SpawnTable: https://paste.helpch.at/ifevuhazuf.cpp
SpawnCommand:
https://paste.helpch.at/usenonuzeb.java

[lyric gyro]

i still get the error still

[neon wren]

Read the errors, as it clearly mentions what they are.

For example UUID of added entity already exists: EntityHorseDonkey['Donkey'/504, uuid='02b7d21a-5d09-4b25-adfc-249e5fc502a2', l='ServerLevel[world]', x=133.15, y=64.00, z=-180.85, cpos=[8, -12], tl=61141, v=false]

[lyric gyro]

thats not the error thats just a spawning error

thata somthing do do with my world entitys

its te bottom bit i cant figure

[neon wren]

Your database takes way too long to respond.

[broken elbow]

its blocking the main thread

[neon wren]

Which causes the server to lock up as it thinks its dead.

[lyric gyro]

so how would i go about fixing that its my first time every using HikariCp

[neon wren]

It's definitely not a HikariCp issue, but rather how you do your queries.

At some point, one of your connections go null in the pool, or all of them, and the database causes the main thread to be blocked.

[lyric gyro]

can i just check if the connection is null ?

[lyric gyro]

No, you should fix the way you use connections
Closing connections/statements/result sets is one step forward, but because you are (currently) closing them manually, there are places where they aren't closed and are still open, occupying a "connection slot" where it's no longer needed and most likely causing some or another mem leak (see those getX/Y/Z/Yaw etc methods, if the result is found you return immediately without closing the resources)
Thankfully Java can close them "automatically" for you when you return or if an exception is thrown, that's what the "try with resources" is for, the way you're doing it now is like this

try {
  Connection connection = coreDatabase.getConnection();
  PreparedStatement statement = connection.prepareStatement("blah blah");
  // ... set statement arguments
  ResultSet resultSet = statement.executeQuery();
  // use result set

  // oh no! you have a return statement somewhere in here and you're not closing the closeable resources!

  resultSet.close();
  statement.close();
  connection.close();
} catch (SQLException ex) {
  // oh no! perhaps the closeable resources weren't closed!
}

Again, closing them is a step in the right direction, but since you're doing them yourself there are missing spots
The try-with-resources (or just twr for short) will close them for you

try (  // note these parentheses
  Connection connection = coreDatabase.getConnection();
  PreparedStatement statement = connection.prepareStatement("blah blah");
) {
  // set statement arguments
  try (ResultSet resultSet = statement.executeQuery()) {
    // use result set
    // you can safely return here, the twr will close everything for you :)

    // no need to call .close() anywhere!
  }
} catch (SQLException ex) {
  // even if an exception is thrown, everything will be closed and cleaned up for you
}

It can be a little bit tedious to change but it's crucial for connection lifecycling and it's not significantly different in terms of "physical" code changes
@lyric gyro

so true

[broken elbow]

LMAO

[icy shadow]

shut up

[lyric gyro]

fuck you

[neon wren]

wow emily copied me.

but did more detailed comments.

[lyric gyro]

lol

[warped kestrel]

Hi kgm

[lyric gyro]

if i do it in this format would i need to close the connection at all ```try ( // note these parentheses
Connection connection = coreDatabase.getConnection();
PreparedStatement statement = connection.prepareStatement("blah blah");
) {
// set statement arguments
try (ResultSet resultSet = statement.executeQuery()) {
// use result set
// you can safely return here, the twr will close everything for you :)

// no need to call .close() anywhere!

}
} catch (SQLException ex) {
// even if an exception is thrown, everything will be closed and cleaned up for you
}```

you don't, java does

okay ill switch it all over too that then

[warped kestrel]

Is it possible to make smoking plugin

[lyric gyro]

sure /effect give <player> nausea

[warped kestrel]

That an effect

But sure
