@lost matrix it worked, thank you

[lost matrix]

He is not trying to check if a block is within a BoundingBox but get every Block within a box.

[raven ore]

https://i.imgur.com/yEjfvp2.png
@stone sinew

[lost matrix]

I at least hope he doesnt check if a block is within the bounds like that

[stone sinew]

add the commas that are missing

[raven ore]

yes i found but cancel() doesnt exist

[stone sinew]

Ah shit yeah forgot. One sec

[stone sinew]

there I forgot the BukkitRunnable portion

[raven ore]

where ?

[stone sinew]

on task Timers where you want them to be able to be cancelled.

[devout spoke]

why I can take items from inventory if I set it e.setCancelled(true);
I can take only with shift click

[vague mason]

why would he need to do that?

[stone sinew]

if(event.getAction() == InventoryAction.HOTBAR_MOVE_AND_READD || event.getAction() == InventoryAction.HOTBAR_SWAP || event.getAction() == InventoryAction.MOVE_TO_OTHER_INVENTORY) {
    event.setCancelled(true); p.updateInventory();
}

[white quiver]

Oh I didn't know about those. I installed maven, what should be my next step?

[eternal night]

if you are trying to setup a spigot plugin using maven, there are a bunch of nice tutorials out there

[bronze night]

btw, how can i do that?

[eternal night]

https://www.spigotmc.org/wiki/spigot-maven/ this is a written tutorial.
https://plugins.jetbrains.com/plugin/8327-minecraft-development can create the entire project layout for a spigot plugin using maven for you

[devout spoke]

thanks

[stone sinew]

NP. If it still doesn't work can always add a delay and remove the item and reupdate the player inventory.

[severe oracle]

i have: java @EventHandler public static void onRclick(PlayerInteractEvent event) { Player player = event.getPlayer(); if (event.getAction() == Action.LEFT_CLICK_AIR && player.getInventory().getItemInMainHand().getType() == Material.AIR) { and for some reason ti sometimes triggers when i rightclick on villagers.

[eternal night]

left click air is triggered every time the client sends an animation packet for the arm swing which happens when interacting with villagers afaik

there is sadly no better way to trigger left click air, as the client does not communicate it :/

[severe oracle]

ok thank you

[terse orbit]

How would I add onto a PersistentDataType.LONG_ARRAY

[lost matrix]

Idk. Maybe he wants to fill an area with blocks or check if there is a certain type of block inside.

[eternal night]

final long[] newData = new long[]{1};
final long[] data = persistentDataContainer.get(namespacedKey, PersistentDataType.LONG_ARRAY);
final long[] updatedData = ArrayUtils.addAll(data, newData);
persistentDataContainer.set(namespacedKey, PersistentDataType.LONG_ARRAY, updatedData);

something around that ?

basic concept is to just get the array -> create a new one that contains the old one plus the added array -> store the new one

[lost matrix]

I always use System.arraycopy for that

[eternal night]

the apache utils does too

[vast sapphire]

How do I make a kill counter

[median anvil]

is there a way to make the plugin run before all other plugins?

[true perch]

Trying to think of a good way to generate blocks from a starting point dependant on which direction the player is facing. Here's a reference picture: (0,0 being the start location). I could for sure do this without problem if it were just one direction, but I want this to work with North, South, East, and West. Any thought? https://i.imgur.com/mS6F6Ea.png

[lost matrix]

No. What are you trying to do?

[median anvil]

world delete plugin, where on startup before world is generated it deletes the world file contents.

[eternal oxide]

So many doing that today

[median anvil]

i got the delete part

[eternal oxide]

did some server just do a popular game mode or something?

You are the 4th person today to ask how to do it

[median anvil]

Idk, but i'm remaking a very very old gamemode

[true perch]

If you use the Spigot app within your IDE, you can make your plugin load post world or on startup https://i.imgur.com/csOpvJb.png

[lost matrix]

You can do that in your onLoad method.

[median anvil]

@true perch thats what im using, but its still not working

@lost matrix is onload an event just like onEnable?

[true perch]

I never tried it, I always assumed it worked.

[vast sapphire]

I think they go by alphabetical order?

so set it to 1 or something?

[lost matrix]

Its a method you can overwrite in your JavaPlugin. Just like onEnable()
But be aware that you can basically not use anything spigot related as nothing is loaded properly at this time.

[eternal oxide]

in onLoad, check Bukkit.getWorlds().isEmpty() then recursive delete all files and folders for your main world.

[true perch]

Anyone know a good way of doing this?

[eternal oxide]

You must check worlds is empty or you will attempt to delete an active world if you do a reload

[floral pewter]

Hey, I'm having some trouble with the remapped version of 1.17. I get an error where an obfuscated class is missing when running my plugin after having reobfuscated it it with specialsource.

Here's a section of my pom.xml:

And here's the error I'm getting

[eternal oxide]

SO much spam. Not read a line of it

[floral pewter]

Sorry for the spam, I realise now that I should have uploaded them as files

[eternal oxide]

Check the nms section https://www.spigotmc.org/threads/spigot-bungeecord-1-17-1-17-1.510208/

[floral pewter]

Here's the pom.xml: https://pastebin.com/CRvmChW6
Here's the error: https://pastebin.com/9jrKBbxM

I read the 1.17 post, which I used to add the specialsource plugin

[median anvil]

what about deleting the file after the world has been saved. unfortunately the onDisable event occurs before the world is saved, so it will delete the file and then save it again.

[floral pewter]

And that the remapped jar should be distribution ready

[eternal oxide]

You are using maven so you don;t need specialsource

[floral pewter]

But I need to reobfuscate it if I want to distribute the files legally, no?

[eternal oxide]

When choosing to use the 'Mojang Mappings', it is absolutely imperative that you are aware of the conditions attached to them as well as the Mojang EULA. These are not restrictions you can simply ignore. In particular you may only 'use the mappings for development purposes'. This means that you must only use the remapped-mojang jar for development and must remap your plugin prior to distribution. For those **not** using Maven you can download SpecialSource to help you do this here, and we encourage the creation of instructions/tools for other build systems.

[floral pewter]

I'm pretty sure I have a dependency on the deobfuscated jar file, and that the specialsource-maven-plugin reobfuscates it for distribution

Or have I misunderstood the post?

[eternal oxide]

It reads to me that the Maven section does it all for you

I have never done it so I'm just going on what I've read and others have said

[floral pewter]

Ah

When compiling and testing my plugin without the specialsource-maven-plugin I get another error:https://pastebin.com/vrL6BW6h

Which makes sense, since the server doesn't use mojang mappings if I'm correct

[wary harness]

how would I check if ArrayList of Locations already contains location

would it be better to use hashmap for it

and use cordinates as key

or something

[ivory sleet]

Set

Maybe

(:

[lost matrix]

Try this

  public void cloneInDirection(final Block start, final BlockFace face, final int count) {
    final BlockData data = start.getBlockData();
    final Location base = start.getLocation();
    for (int i = 0; i < count; i++) {
      base.add(face.getDirection());
      base.getBlock().setBlockData(data);
    }
  }

[true perch]

Oooo I will try it! Thank you a ton ❤️

[wary harness]

what would I get with set ?

[lost matrix]

Hugely better performance.

[ivory sleet]

Well what are you trying to do? Tldr

[lost matrix]

For contains

[wary harness]

so I am calculating some locations adding them to lets say arraylist

[bronze night]

So i want to get the online players and check if they are above or equal to 1 and im getting this error in console and i don't know how can i fix it doe

[ivory sleet]

The set interface guarantees no duplicates, however the common implementation HashSet#contains is O(1) if the elements contained have rightfully implemented the Object#hashCode method

[wary harness]

and when u check if it contains(location)

[lost matrix]

A player is not a number.

[lost matrix]

Wait you mean the amount of players

[wary harness]

problem is location is object

[bronze night]

ye

[wary harness]

and it is not same

[quasi flint]

; 7

[wary harness]

even when it has same cordiantes

and when u check if list.contains(location)

[ivory sleet]

yes that’s why I asked for your intentions

[wary harness]

so will

that work with Set ?

[lost matrix]

    final Collection<? extends Player> onlinePlayerList = Bukkit.getOnlinePlayers();
    final int countOfOnlinePlayers = onlinePlayerList.size();
    if (countOfOnlinePlayers > 0) {
      // Do stuff
    }

org.bukkit.plugin.InvalidPluginException: java.lang.UnsupportedClassVersionError: pluginpack/Plugin has been compiled by a more recent version of the Java Runtime (class file version 59.0), this version of the Java Runtime only recognizes c```

[wary harness]

because I am confused a bit now xd

[ivory sleet]

Well give us the entire picture

[mellow edge]

how can I fix that?

[lost matrix]

Compile time java version doesnt match server java version

[bronze night]

ahh

i saw it rn

[mellow edge]

so...

[bronze night]

the "onlinePlayerList.size()"

XD

thanks for help

[lost matrix]

Either compile with an older java version or update the version that is running the server.

[lost matrix]

Just to make it very clear

[mellow edge]

I think it was compiled with java 15 but my server is using java 8

[lost matrix]

You should compile and run your jars with java 16.
This is even required for the newest version.

[mellow edge]

im using version 1.16

[lost matrix]

Are you using maven?

[mellow edge]

no

[lost matrix]

Then no idea how to change the compile src version...

[wary harness]

so what I am doing is calculating some shapes and then adding there location to list
sometimes I get same cordinates because I am using Math.round
and I don't want the multiple location object with same cordiantes
and if I check if list.contains(location)
it wont work because every location is differenet object but they can have same coordinates

[lost matrix]

Ah wait i know.

[mellow edge]

lol I can just copy my code into jdk8 project

[lost matrix]

Or you change the version of your current project

[mellow edge]

that's good idea!

[lost matrix]

This will not work in most cases because you very very very rarely get the same Location twice.

Also List#contains scales suuuper bad

[sharp bough]

does anyone have a decent amount of experience with fabric that can answer a few question?

[lost matrix]

Do you want to fetch the list of mods published by the client?

[worldly ingot]

I'd have used Block#getRelative(face) so you can skip the whole Location construction.

public void cloneInDirection(final Block start, final BlockFace face, final int count) {
    Block current = start;
    BlockData data = start.getBlockData();

    for (int i = 0; i < count; i++) {
        current = current.getRelative(face);
        current.setBlockData(data);
    }
}```

Either works though

[mellow edge]

or in eclipse I think that I must just that:

[bronze night]

btw, how can i broadcast textcomponent?

[lost matrix]

Yeah this looks nice

[sharp bough]

no, a guy is asking me to make a MCMMO type of thing but in fabric, i never really used it and i was wondering if it worth it, what can you do with it and is it better than spigot or a waste of time

[mellow edge]

Java compiler

[sharp bough]

i already found the documentation

is it possible that you can add items?

https://fabricmc.net/wiki/tutorial:armor

[lost matrix]

Completely different platform and target audience.
Every player that wants to join a Fabric server has to download and install all mods.

[sharp bough]

im not sure what it is creating

[lost matrix]

Fabric is not targeted towards public servers but rather small, closed communities where every player

knows each other.

[mellow edge]

bdw why I can't paste pictures in this chat?

[lost matrix]

You are not verified

?verify

?verified

idk

[mellow edge]

ok I will quickly do that

[sharp bough]

https://www.reddit.com/r/fabricmc/comments/htiup7/i_made_a_list_of_fabric_server_side_mods/
but you can create the mods server side?

[lost matrix]

Sure. But every client still has to download the mods.

[sharp bough]

ah

[lost matrix]

He has to go to a website. Install Fabric and then download and install each mod that is on the server.

Manually

[mellow edge]

I must make spigot account and than verify it?

[lost matrix]

Sure

[sharp bough]

aight lets say the player now downloads all mods, what could a mod do? is it like spigot where you can edit an event and execute something or you can customize things like internal data of items, create new blocks and stuff like that

[lost matrix]

You can do absolutely everything you want.
There are no limits. Only your knowledge and time will determine whats possible.

[worldly ingot]

With Spigot you're restricted to the server. On Fabric you can manipulate both the server and the client

That is unless you're making a Fabric mod that should be useable on a non-Fabric server in which case you're bound to the client

[sharp bough]

and the client? thats interesting, lets say i want to create the good old emerald pick, i could make the texture, add the values to it and make it work?

both server and client side

[worldly ingot]

Yes, though the server would have to be a Fabric server running your mod so it recognizes and registers your pickaxe properly

[sharp bough]

and then client side shows the new pick

[worldly ingot]

Can't make an emerald pickaxe and expect to join a vanilla or Spigot server for instance

Yes

[sharp bough]

shit thats insnae

thx

[worldly ingot]

It would be a new item in the registry

👍

[lost matrix]

This will give you a glimpse of whats possible:

@ivory sleet

r u chatting in a mc server rn?

[bronze night]

i have another question, so somehow i managed to create the script(with some help) that sends a message when there is 1 or more players online, every 10 minutes, and now i don't know how to register it into the main .java file

[lost matrix]

https://www.spigotmc.org/wiki/using-the-event-api/

[bronze night]

but i didn't put any @brave glenHandler there

or should i ?

[lost matrix]

I dont know what you are doing. Ive seen a ServerListPingEvent before from you so i just guessed you
dont know how to register events.

[bronze night]

like

wait

lemme try something

[quaint mantle]

hello iam about to edit the Essentials plugin tho i encountered a problem.. i want to change colors but i dont know how to do it is there any other way instead of changing the .jar file itself

[lost matrix]

You should never access and change a .jar file.

[quaint mantle]

uu nice to know they are very messy

[lost matrix]

Here is the source code of essentials:
https://github.com/EssentialsX/Essentials

[quaint mantle]

look i just used the Java Decomplier and see the color is $6

but i cant copy that part

and insert it to my text editor

[lost matrix]

Dont do that. Doesnt Essentials have enough config files for that?

[quaint mantle]

yes i looked that up

[quaint mantle]

i want to change it in locale (and no they dont have setting for color itself)

[quaint mantle]

the problem here is that i dont know where is the locale file

[lost matrix]

If you dont have prior java experience then you will not be able to just change a jar on the fly.

[bronze night]

something went wrong

[true perch]

Does anyone know why the block at the desired location isn't being set to stone?java @EventHandler public boolean onTablePlace(BlockPlaceEvent e){ e.setCancelled(true); Location location = e.getBlockPlaced().getLocation(); generateTable(location) } public void generateTable(Location location){ location.getBlock().setType(Material.STONE); }

[bronze night]

so i did this

[lost matrix]

Try a one tick delay

[true perch]

Alrighty

[bronze night]

so

should i add EventHandler there?

[lost matrix]

1. This does nothing
2. This will just straight up crash your server

[bronze night]

it didn't somehow

XD

[lost matrix]

*If it runs once

[bronze night]

hm

[lost matrix]

Do you call this method somewhere?

[bronze night]

nope

[true perch]

public boolean generateTable(Location location, Player player){

    new BukkitRunnable() {
        @Override
        public void run() {
            cancel();
        }
    }.runTaskTimer(YuCraft.MAINPLUGIN,1,0);

    location.getBlock().setType(Material.STONE);
    return false;
}```the delay didn't help

[mellow edge]

org.bukkit.plugin.AuthorNagException: No legacy enum constant for FIRE_CHARGE. Did you forget to define a modern (1.13+) api-version in your plugin.yml?```

[lost matrix]

This is not a delay. This does nothing.

[quaint mantle]

[mellow edge]

what must I implement in plugin.yml then?

XDD what?

[paper falcon]

you mean on cracked servers when players have to /register ?

[lost matrix]

You can fiddle with bytecode. But you shouldnt.

who doesn't love breaking shit

[quaint mantle]

holy.. i did it 😄

[lost matrix]

What plugin? We need more information. I dont think any half decent plugin uses readable Strings for authorization.

I mean you can listen for the PlayerCommandPreprocessEvent and read the values from there

[mellow edge]

and also plugin now somehow load and then it stops because that message occurs: [22:58:34 ERROR]: Error occurred while enabling fireball v1.16.5 (Is it up to date?) java.lang.NullPointerException: null

[worldly ice]

you have to instantiate the itemstack to change the item

Does anyone know how to get default item attributes without NMS?

What do you want to do with the ItemStack?

[paper falcon]

use it in another class without having to copy-paste it there

Then make it a static reference

You could do public static ItemStack item = new ItemStack(Material.EMERALD);
Then do ClassName.item to get said static object.

is it possible to use breakNaturaly()

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

[wary harness]

So what I am saying I am braking block which are in HashSet

but will it breakNaturaly() check if event is cancled

[eternal oxide]

If you want to see if other plugins are going to prevent the block break you need to fire an event so they can see your attempt

[wary harness]

does it even runs block brake event

so I need to call

BlockBrakeEvent

for every block

[eternal oxide]

and check the cancelled state

[wary harness]

ok thanks

I was thinking breakNaturaly()

runs event

when u use it with getBlock().breakNaturally(e.getPlayer().getItemInHand());

thanks

[eternal oxide]

You can test it but I don;t believe it does

[wary harness]

I need to grab all those block

and give drops to player direcly to inventory

so best will be to call event

I'm making a plugin where I listen to BlockBreakEvent and use event.setDropItems(false) to stop items from being dropped from the block that was broken. However, this seems to also stop items from being dropped from blocks that "depend" on the block that was broken, such as torches, flowers, levers, etc. I initially thought that maybe two BlockBreakEventss were being called, but that doesn't seem to be the case. It this a bug or expected behaviour? If it's expected behaviour, how do I get around it (no hacky ways please)?

i created this file, stuff.java
how would i use it inside main java file?
is it even correct lol

[unreal quartz]

wat

[gaunt saffron]

how do i tell the plugin to run this

[crude charm]

m8

uh

what

[unreal quartz]

by putting it in a plugin

[crude charm]

[gaunt saffron]

okay

do i need to call it from the plugin itself?

[crude charm]

...

[gaunt saffron]

yeah i dropped java 8 years ago 🙄

[unreal quartz]

void doThing() {
// thing
}

onEnable {
doThing();
}

[crude charm]

should probs refresh your self

?learnjava

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

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

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

[gaunt saffron]

should, but then, i just need like 10 plugins and hoping to cheese thru and dont touch it even again

[unreal quartz]

what you're asking isn't even a java specific question

it's just.. common sense

[gaunt saffron]

well i know i need to load/import it, question how

[unreal quartz]

r

[gaunt saffron]

okay whatever can't get worse than errors

but takes like 1-2mins to run...

[wary harness]

custom enchant

so if I call manually block brake event

that will not brake block

[gaunt saffron]

crap, it's not giving me anything except 200 code... no data
thouight responsemessage would give me smth

[crude charm]

@timid root

[timid root]

hello

[crude charm]

hi

[timid root]

ive got to go

ill be back on soon

[crude charm]

how soon?

[median anvil]

can you cancel the enderpearl teleportation event inside the onProjectileHitEvent?

or can you at least get a cast of the Enderpearl that caused the teleportation in the TeleportationEvent?

[unkempt peak]

What are you trying to do?

[median anvil]

cancel the teleportation of the enderpearl depending on the lore of the enderpearl

[hexed hatch]

what you should do is listen for the PlayerInteractEvent, and if the enderpearl meets your criteria, set the owner field to null

[median anvil]

ooo

[hexed hatch]

that's the cleanest solution really

[unkempt peak]

Yeah

[median anvil]

never thought of that. can you set the owner field in player the onProjectileLaunch event?

[quaint mantle]

Lore is exploitable

[hexed hatch]

yeah

[median anvil]

k

[unkempt peak]

Use a persistent data container

[hexed hatch]

As long as you can get the projectile it will work

[quaint mantle]

tell me why you are using lore over PDC

[hexed hatch]

because lore is uncomplicated

[unkempt peak]

So is pdc

[quaint mantle]

its horrible and unsafe

[hexed hatch]

localized-name is a good way for identifying custom items

[quaint mantle]

yet its not

[hexed hatch]

eh

[quaint mantle]

?pdc @median anvil

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[median anvil]

idk what pdc is

[quaint mantle]

learn

[hexed hatch]

pdc is better

[median anvil]

ive been using lore for everything xD

[unkempt peak]

Persistent data container

[quaint mantle]

its easy

[median anvil]

damn.

[unkempt peak]

Store data in an items json

[hexed hatch]

lore is pretty gross for item identification, especially if you're iterating through multiple lines

[quaint mantle]

then you shouldve suggested it to him

[hexed hatch]

but for the sake of simplicity, localized names work well

I didn't suggest it to him forehead

[unkempt peak]

Simplicity deos not always mean good

[quaint mantle]

you said names are good

[hexed hatch]

localized names

[median anvil]

i've been using lore cause I watch youtube and thats what they do... thanks for telling me pdc exists tho.

[quaint mantle]

codedred?

[hexed hatch]

That's not the display name field, it's invisible meta on the item intended for resource pack translation

[median anvil]

YES

lol

[quaint mantle]

hes a bullshitter who spreads bad code

[hexed hatch]

localized name =/= display name

[median anvil]

his code has worked for me so far, but then again im new to java in general so...

[hexed hatch]

yeah his practices suck

[quaint mantle]

its working code but bad code

[hexed hatch]

he's one of the ones I used in the beginning lol

[unkempt peak]

Wow ok just because his code may not be the best does not mean he is bad. He is helping people understand spigot for free. Obviously there are some things that he should improve but there is no reason to hate.

[median anvil]

well, ill probably rewrite my plugin the correct way after I get everything working.

[quaint mantle]

when tf did I say he was bad

[hexed hatch]

lol the good ol' "I'll make it better later" manuever

fun fact: it never happens

[worldly ice]

true

[median anvil]

I'll try, i'm still a beginner. I'm already on my second rewrite actually.

each time i get further and further

btw the I grabbed the enderpearl and set the shooter to null but it did not work, i still teleported.

[hexed hatch]

Send your code please

In a code block if you know how

Or better yet

?paste

[undone axle]

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

[hexed hatch]

make sure you're registering your listener

and when something doesn't work, put some lines that output a string right above the part that makes the change to see if it even fires

[median anvil]

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

[worldly ice]

Any errors?

[hexed hatch]

@median anvil is there a setOwner method?

I see you have setShooter, see if there is a setOwner method as well

[median anvil]

no

there isnt

[hexed hatch]

Is this listener registered?

[median anvil]

a setOwner method nor any errors

yes

[hexed hatch]

Put a System.out.println("ooga"); above that

[worldly ice]

ooga

[hexed hatch]

see if it's even being reached

[glossy scroll]

setShooter

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Projectile.html#setShooter(org.bukkit.projectiles.ProjectileSource)

also looked at ender pearl code

can confirm

it is setShooter

[hexed hatch]

Cool

[median anvil]

https://gyazo.com/dc74dedcfa8c188b074cfdc27cafa00f

Bukkit.getConsoleSender().sendMessage("TESTING ENDERPEARL");enderPearl.setShooter(null);

its being reached just not doing anything.

[worldly ice]

Maybe a getShooter() after that to test if it's actually null?

idk

[glossy scroll]

what version of spigot are you using

[median anvil]

1.17.1 from intelij plugin

java.lang.NullPointerException: Cannot invoke "Object.toString()" because the return value of "org.bukkit.entity.EnderPearl.getShooter()" is null

[worldly ice]

hmm

[median anvil]

it is turning it null, but its still teleporting me

I event tried canceling the enderpearl land event, but still teleported me.

[worldly ice]

Can you confirm that you can modify the ender pearl in other ways?

i have no idea at this point

possible forum thread about it? https://bukkit.org/threads/cancelling-enderpearl-teleport-from-projectile-hit-event.404620/

[median anvil]

yeah, I set it to explode when it hits the ground.

[worldly ice]

the op specifically states that setting the shooter to null didn't work

[median anvil]

it explodes, but also teleports me into the explosion

[mighty vine]

is there a post thats realy indeeph about what to learn. I know post say learn OOP learn abstract learn java öearn spigot but not deep pls @ me if you have link or can tell me deeper

[quaint mantle]

thats all it is lol

[mighty vine]

what is all it

I need 1 to 10 step by step with sentences I can put into google

[quaint mantle]

1.Maps rarely are passed through classes

2. Never hardcode if statements for things like quests, skills, create check objects

3. Always create an API for your classes and allow everything to be changed

4. Javadoc everywhere

5. static isnt to make life easier

6. understand OOP

7. abstract everything

8. understand object constants vs enums and when to use them

[median anvil]

i did it by deleting the enderpearl when it hit the ground!

[mighty vine]

thx imaginedev but I dont understand the first two. Can you show examples where its right and where its wrong thx

[open vapor]

best way to store data permanently?

[worldly ice]

In an entity?

or just data in general

[open vapor]

in general

[worldly ice]

Use a config file

[median anvil]

so is pdc part of nms?

cause i've been storing my persistent data as lore in items xD

[quaint mantle]

ye

[median anvil]

i didn't even know pdc existed. but now i'm interested

[quaint mantle]

its like easy nbt

[median anvil]

i don't think i can do nbt/nms with the spigot plugin im using in intelij cause it doesnt have the imports. I was trying to follow a tutorial on creating npcs, and I couldn't cause I dont have the nms imports.

[quaint mantle]

you dont need it

pdc handles it all

[median anvil]

okay.

@quaint mantle will persistent data be injected into the block placed from the block item in hand?

so if i had an itemstack of blocks with persistent data, and placed a block, would that placed block hold the data I stored in the Itemstack of that block?

[quaint mantle]

no

[median anvil]

oh.

[quaint mantle]

It will

had to do some research

but it only works on certain types

Banner, Barrel, Beacon, Bed, Beehive, Bell, BlastFurnace, BrewingStand, Campfire, Chest, CommandBlock, Comparator, Conduit, Container, CreatureSpawner, DaylightDetector, Dispenser, Dropper, EnchantingTable, EnderChest, EndGateway, EntityBlockStorage<T>, Furnace, Hopper, Jigsaw, Jukebox, Lectern, SculkSensor, ShulkerBox, Sign, Skull, Smoker, Structure

[median anvil]

Well I was thinking chests and stuff

okay awesome!

[quaint mantle]

oh yeah

go for it 👍

[median anvil]

I wish I knew about pdc before writing thousands of lines of code depending on lore...

[quaint mantle]

[neon kestrel]

        PlayerInventory playerInventory = player.getInventory();
        playerInventory.clear();
        playerInventory.setExtraContents(null);
        playerInventory.setItemInMainHand(null);
        playerInventory.setItemInOffHand(null);
        playerInventory.setArmorContents(null);
        playerInventory.setStorageContents(null);
``` How do I clear the little crafting area in the player's inventory? I've managed to clear every other part of the player's inventory except for this

Ended up closing the inventory first then clearing it

[quaint mantle]

save contents
close
set contents

[median anvil]

can you allow crafting recipes under certain conditions/permissions?

[worldly ingot]

Yes. There's a PrepareItemCraftEvent you can use

To check which recipe is in the table in that event, there's a getRecipe() method

[quaint mantle]

Choco choco

[median anvil]

ty

[quaint mantle]

# Yes, the file extension is .ASS
# Cry about it.

final var name = prompt()
print('Hello', name) 

@worldly ingot Choco likes?

[worldly ingot]

I like .ass, I don't like the mangling of Java & Python

lol

[quaint mantle]

Sad

[worldly ingot]

What is .ass? Async script? ;p

[quaint mantle]

Assess

im making it

[worldly ingot]

Figured as much

[quaint mantle]

Choco Choco rate syntax

[median anvil]

with the PrepareItemCraftEvent can you check if the event.recipe is equal to a custom recipe you created?

[worldly ingot]

Yeah. Check if the Recipe is an instanceof Keyed. You can then cast it and getKey(), compare it to the key you used when you created the recipe

Recipe recipe = event.getRecipe();
if (recipe instanceof Keyed keyed && !keyed.getKey().toString().equals("yourplugin:key")) { // or equals() the NamespacedKey directly
    return; // Return if it's not your recipe
}

event.getInventory().setResult(null); // Remove it from the result under x condition

[median anvil]

@worldly ingot i have a separate class that holds my custom recipes in functions that return the recipes

example function from my class CustomRecipes: https://paste.md-5.net/ecanuqayim.cpp

[quaint mantle]

creating a new recipe everytime its called

[median anvil]

its only called once on startup

[quaint mantle]

Ok

still though

[median anvil]

how would I access that recipe / key?

the instanceof Keyed keyed is what is confusing me rn.

[worldly ingot]

Java 16 feature

Equivalent to

Recipe recipe = event.getRecipe();
if (recipe instanceof Keyed) {
    Keyed keyed = (Keyed) recipe;
}

[lavish hemlock]

did you know: Choco likes ass?

[median anvil]

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

this should work right?

cause its not

[lavish hemlock]

it should be namespace:seed_stew

replace namespace with wherever it comes from, e.g. minecraft

[median anvil]

I set the namespace as the plugin I think

[worldly ingot]

getKey().equals("some string") will never be true

Note in my initial snippet I did getKey().toString().equals("some string")

NamespacedKey.equals(String) is impossible. String.equals(String) however.

[median anvil]

Amazing, thank you!

[sage pine]

Hey guys I have a question for you if you know the answer i'd really appreciate it.

My server pulls the docker container image for about 4 minutes. When it finally pulls it after 4 minutes, the server starts like normal. But what is causing the container image to be so slow?

It's a rise-2 from OVH. I have 18G allocated to the docker container, and only 14 on the actual minecraft server (4g heap)

Hey! quick question: I was dealing with JDBC yesterday and asked for help here in this regard. Someone helped me and gave me an example of how to create a DataSource.Then I created the following class:

public static DataSource MySQLDataSource() throws SQLException {
        MysqlDataSource dataSource = new MysqlConnectionPoolDataSource();
            File file = new File("D:\Programming\Plugins\sfspConfig.yml");
            YamlConfiguration yamlConfiguration = YamlConfiguration.loadConfiguration(file);
                dataSource.setServerName(yamlConfiguration.getString("host"));
                dataSource.setPortNumber(yamlConfiguration.getInt("port"));
                dataSource.setDatabaseName(yamlConfiguration.getString("database"));
                dataSource.setUser(yamlConfiguration.getString("user"));
                dataSource.setPassword(yamlConfiguration.getString("password"));

                testDataSource(dataSource);
                return dataSource;
    }

    private static void testDataSource(DataSource dataSource) throws SQLException {
        try (Connection conn = dataSource.getConnection()) {
            if(!conn.isValid(1000)) {
                throw new SQLException("Database not connected!");
            } else
                System.out.println("Database connected!");
        }
    }

However, now I don't know how to continue. Can anyone help me there?

[stoic ravine]

I made two actions now, is this good enough to register if the player right cliekd an entity?

        UUID uuid = e.getPlayer().getUniqueId();
        Player p = e.getPlayer();
        Class clasS = Main.getClassManager().getClass(uuid);
        if (clasS.equals(Class.PRIEST)) {
          Entity action = e.getRightClicked();
          if ((action.equals(action) && ```

[burnt current]

Oh yes, there was also that. Thank you

[stoic ravine]

if ((action.equals(action.getType() == EntityType.ZOMBIE) ahhh like this, but can I do an entitytype for all entities there is?

[hybrid spoke]

you can loop over the entitytypes

[hybrid spoke]

for(EntityType entityType : EntityType.values())
    if(entityType == EntityType.ZOMBIE) System.out.println("a zombey");

[stoic ravine]

I see

How can I store PacketPlayOutMap in files efficiently?

actually my goal is to be able to cache again every of my PacketPlayOutMap after restarting serv

[mellow edge]

how can I make that BukkitRunnable will repeat the proces 10 seconds

.runTaskTimer(this, 0L, 2L);

[candid galleon]

It’s in ticks, 20 ticks = 1 second

2 would be 1/10 of a second

[tame coral]

So 10*20 = 200 ticks !

Mafs

[mellow edge]

so 20L I must put there then?

[candid galleon]

If 2 is 1/10 of a second what do you think 20 is

[mellow edge]

10

[candid galleon]

think carefully, because I did also just say

1 / 20 ticks per second * 20 = Once per second

[mellow edge]

ok

so 200 ticks is 10 seconds if I undestand

[tidal skiff]

is there any way to get a twitch chat into minceraft with spigot

[ivory sleet]

Yep

[ivory sleet]

Probably, there’s probably some sort of webhook you could use

[mellow edge]

you will need some sort of library or something like that

[tidal skiff]

i think i have one but i have no idea how it owrks

[mellow edge]

you can just find an example on internet

[upbeat sky]

I'm having trouble compiling my plugin. I get this error:
org.bukkit.plugin.InvalidPluginException: Cannot find main class `nl.naimverboom.aresessentials.GeneralClasses.AresEssentials'
In my plugin.yml, I have this:

[quaint mantle]

packages lower case only

[upbeat sky]

That's not going to fix the problem I'm facing

[chrome beacon]

Well does your main class exist in that location

[upbeat sky]

It does

[mellow edge]

how to check if block is blast protected

[chrome beacon]

Show us because the error says it doesn't

[paper falcon]

your main: should be the one where you have public onEnable() method

[chrome beacon]

Wrong package

You need the entire thing not just the ending

[upbeat sky]

You mean on the top?

[chrome beacon]

Yes

[upbeat sky]

Wait I think i found the problem

Alright

The problem was very dumb

if you look at the project files i forgot to wrap everything in a package

[mellow edge]

how to check if block is blast protected

[grim ice]

prob nms

or some hacky code

[opal juniper]

what so like if they are sneaking completely ignore it

[devout spoke]

why when I try to teleport the location I create here

                World world = plugin.getServer().getWorld(data.getString("world"));
                Location location = new Location(world, data.getInt("LocX"), data.getInt("LocY"), data.getInt("LocZ"));

its gives me an error java.lang.IllegalArgumentException: location.world
and when i try to create item there it works?

[opal juniper]

ig you could listen to the move event - check how close to the edge of a block they are and if that next block is air disable the crouch

[mellow edge]

can I make egg entity unbreackable? I mean when it colides with a block it won't break

[opal juniper]

what do you mean by break

[chrome beacon]

Eggs break when they hit a block

Looks like he wants to just have a bunch of eggs floating or smth

[opal juniper]

ew

thats gonna be laggy as hell

[grim ice]

not really?

[opal juniper]

well

it depends on how many eggs

[grim ice]

except if u have a very shitty server

[mellow edge]

I can just when player throws it get his position into 3 intagers and then when the egg breaks I can just spawn new one in the same direction

[mortal hare]

how to check if block is blast protected
@mellow edge im pretty sure Material enum class has method to check if enum block type is unbreakable

I could be wrong tho

[maiden briar]

Is there a way to get it higher? java.lang.IllegalArgumentException: Health must be between 0 and 20.0, but was 20.200000762939453. (attribute base value: 20.0)

[summer scroll]

So I just switched to java 16 for 1.17.1 plugin and I received a warning saying that's the class could be a Java Record, and I'm wondering If it will have the same effect like the dependency injection. Because I originally want to pass my main class to other class and I got this warning instead.

public record PlayerEvents(PersonaPlugin plugin) implements Listener {

}

It's like lombok tbh lol

[chrome beacon]

Set max health to higher with an attriubute

[maiden briar]

Ok so the attribute is able to have a higher value?

[chrome beacon]

Yes

That will give more hearts

[maiden briar]

Do I have to set baseValue?

[chrome beacon]

Believe so

[maiden briar]

Ok thx

And what is the max value Minecraft allows?

[chrome beacon]

Float or double max

Can't remember

[stiff ember]

infinite i think

[chrome beacon]

Probably float max

[stiff ember]

well yeah

that

lol

[maiden briar]

https://minecraft.fandom.com/wiki/Attribute Sadly it's only 1024 😦

[chrome beacon]

Aight

Why do you even need higher

That amount is going to fill your screen

[maiden briar]

Yep true 😄

[tardy delta]

can i combine a textcomponent (clickable message) with a normal string message?

[eternal oxide]

component builder

[tardy delta]

lemme see

aha

[summer scroll]

Got this error on this line, what is the problem? https://paste.helpch.at/uvofuzinal.md

[eternal oxide]

Thats not the line that gave the error, but it is the text you sent. Use prepared statements

You also definitely don't wank all those columns to be TEXT

[lost matrix]

Ok those readings are a bit weird...

[unreal quartz]

can't use prepared statements to replace table names

[eternal oxide]

no but you can for all the rest

[slim kernel]

Can I somehow delete the item after someone dropped it?

[unreal quartz]

not needed, it's a hardcoded statement to create the table

[unreal quartz]

destory the entity

[lost matrix]

Seems to be -0.5 - 2.0 in 1.17 and for 1.18 will become -0.7 - 2.0

[lean gull]

could still use some help with this

[lost matrix]

You can not cast a String to a Material. Use the method Material.matchMaterial()

[vagrant edge]

how can i obfuscate my code ?
ping me for answers

[lean gull]

how 2 use this

[lost matrix]

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

[lean gull]

i am literally on that webpage

it doesn't really help

[lost matrix]

Use an obfuscator

[vagrant edge]

Like?

[lost matrix]

Material.matchMaterial(String) is a static method of Material that takes a String and returns a Material.

[lean gull]

so like this?
Material.matchMaterial(cfgn.getMaterialsConfig().getString("disableElytraMovementCheckMaterialDisabledConfig"));

[lost matrix]

https://www.letmegooglethat.com/?q=java+best+free+obfuscator

[summer scroll]

I found the error, turns out I can't use desc because it's used for sorting stuff.

[lost matrix]

Yes but thats quite unreadable. Write it line by line.

String materialKey = "disableElytraMovementCheckMaterialDisabledConfig";
String materialString = cfgn.getMaterialsConfig().getString(materialKey);
Material matchedMaterial = Material.matchMaterial(materialString);

[slim kernel]

I tried to delete the Item after it gets dropped but with that method I only delete Items that are already dropped and not the one that I am currently dropping. How can I delete the Item as fast as possible after someone dropped it?

Collection<Entity> list = player.getWorld().getNearbyEntities(player.getLocation().getBlock().getRelative(BlockFace.DOWN).getLocation(), 10, 10, 10, (entity) -> entity.getType() == EntityType.DROPPED_ITEM);
        for (Entity entity : list) {
            Item item = (Item) entity;
            if (item.getItemStack().getType() == RegisterManager.getPlayersElements().get(player.getUniqueId())) {
                item.getItemStack().setAmount(0);
                player.sendMessage("deleted");
            }
        }

  }

[crimson terrace]

^

[slim kernel]

oh

thank you haha

[crimson terrace]

Im pretty sure you can cancel that event too in case there are items you dont want to delete...

[slim kernel]

No I cant cancel it because it triggers my InteractListener then

[crimson terrace]

Oh well

Theres always if()

[slim kernel]

Yeah but I do something on left click Air and it the dropp triggers the left click air and thats the problem

[crimson terrace]

If the event is set cancelled shouldnt it not trigger that anymore?

[slim kernel]

it does because of the swing animation or something:
https://github.com/SkriptLang/Skript/issues/2731

[crimson terrace]

Welp, gotta figure out a workaround then. Maybe try something like a public static boolean you set false when it happens and if its false you cancel the interact event?

Worked for entityspawnevent

[slim kernel]

Its okay I already fixed it but thank you

[trail flume]

Ok so, how can I get what block a snowball hit in 1.8.8?

[tardy delta]

im confused

[crimson terrace]

Never worked with 1.8.8 but isnt there a projectileHitEvent or something?

[trail flume]

Yeah but I need to know what block it hit

[crimson terrace]

Event.gethitBlock or something?

[trail flume]

nope

theres nothing in that event to get the hit block

[crimson terrace]

Am at my phone so i cant check anything really

Anything in event.getProjectile?

[trail flume]

It's getEntity, and no.

I don't need an exact block, shall I just get the snowball's location and round that to a block?

[crimson terrace]

Maybe even use the vector it has before hitting to determine the actual block it hit...

[trail flume]

True

[crimson terrace]

Might be weird around corners tho

[trail flume]

Yeah

[trail flume]

This will work

[crimson terrace]

Write your own getHitBlock method XD

[trail flume]

Nah I'm good ty

XD

[crimson terrace]

😄

[candid galleon]

think it wants the index of the biggest number in the array

[tardy delta]

im confused i forgot how to do it

[trail flume]

Snowball snowball = (Snowball) p.getWorld().spawnEntity(p.getLocation(), EntityType.SNOWBALL);
snowball.setVelocity(p.getLocation().getDirection().multiply(2));
```This isn't going to work is it.

The snowball will instantly destroy right?

[grim ice]

WHY R U CASTING

wait nvm

[trail flume]

XD

[candid galleon]

http://tryitands.ee/

[trail flume]

I did, I'm asking you guy's opinion on it.

[candid galleon]

Well, did it work?

[trail flume]

Sometimes

So I wondered if I'd done something wrong or that was expected

[candid galleon]

as far as I know that should work

[trail flume]

No because it spawns on the player so instantly destroys, adding the players direction to the spawn location fixes that.

[lean gull]

anyone know why i can't use this in another class?

    public static ItemStack createItem(String name, Material mat, List<String> lore, int cmd) {
        ItemStack item = new ItemStack(mat,1);
        ItemMeta meta = item.getItemMeta();
        meta.setDisplayName(name);
        meta.setCustomModelData(cmd);
        meta.setLore(lore);
        item.setItemMeta(meta);
        return item;
    }``` i could before but i did some stuff and for some reason now i can't

nvm

it just doesn't suggest it

[reef wind]

so offset it.. 😐

[severe oracle]

what is wrong herejava public static void brodcastToTeam(Team team, String message) { Player LoopingPlayer = null; for(int i = 0; i <= playersList.size(); i++) { LoopingPlayer = playersList.get(i); if(team.getPlayers().contains(LoopingPlayer)) { LoopingPlayer.sendMessage(message); } } return; } ?

[olive badger]

in your code i think you have nothing wrong, check if the players is in team.getPlayers() and playerList

[eager hinge]

what error are you getting?

is team.getPlayers() a List<Player>?

[severe oracle]

how can i send error ?

[eager hinge]

it it is, then you can simply do to send to all team members

for(Player TeamMember : team.getPlayers()) TeamMember.sendMessage(message)

[severe oracle]

it doesen't let me upload a filr

[eager hinge]

just copy last 5 lines there should be the error message

you can see the two parts, first one is the exception and a stack trace and the second one is the error message

[severe oracle]

the code you send: it returns
Required type:
OfflinePlayer
Provided:
Player

[tardy delta]

null

[eager hinge]

so it's a list of OfflinePlayer? List<OfflinePlayer>

[severe oracle]

for(Player/*not offlien player*/ TeamMember : team.getPlayers())

[eager hinge]

what is the return type for team.getPlayers()

[severe oracle]

Set<offline player>

[eager hinge]

Why are the team members offline players? Can you even send a message to offline player?

[severe oracle]

i don't think so

also i am realy new to java

and i got it to work with:java public static void brodcastToTeam(Team team, String message) { Player LoopingPlayer = null; for(int i = 0; i < playersList.size(); i++) { if(team.getPlayers().contains(playersList.get(i))) { playersList.get(i).sendMessage(message); } } return; }

[eager hinge]

Cool

[eager hinge]

you can try the other version of for too. to learn that

[severe oracle]

other versions ?

[eager hinge]

this:

for(OfflinePlayer TeamMember : team.getPlayers())
  TeamMember.sendMessage(message)

learn about for loop here:
https://www.w3schools.com/java/java_for_loop.asp

but i don't understand why are you using OfflinePlayer. and how can you call the sendMessage method on an Offline Player. That one doesn't exist i believe

[severe oracle]

well i didn't know about for-each as i don't think C has that

[ivory sleet]

it’s actually a while loop when compiled

But yeah syntactic sugar

[severe oracle]

thank you for the help

the code works if i do:java for(OfflinePlayer TeamMember : team.getPlayers()) { TeamMember.getPlayer().sendMessage(message); }

[atomic gyro]

Hey there guys. I've been getting a bunch of differing results when trying to get where a player is looking, and can't really seem to make any of them work. Any tips?

I more or less want to get the entity or block a player is looking at, whichever comes first.

[severe oracle]

do you want to know what block he is looking at ?

or just direction ?

[atomic gyro]

Just what entity they're looking at

[rapid meteor]

what about the command name.

I believe that is done just on the client side as you can change the language in the settings.

found this:
https://www.spigotmc.org/threads/looking-for-the-in-game-enchant-names.290133/
Essentials plugin do that too. The last message also contains a code with the finished thing. You can just copy that and add some new enchanments added since 2017

[limpid veldt]

oof

basically just a switch statement

[rapid meteor]

Can anyone please write me a quick plugin.yml with 1 command.

Please?

[limpid veldt]

thanks anyways tho

[atomic gyro]

I'm having some issues trying to use the RayTraceResult, if anybody can help me with how it works.

[eager hinge]

yeah, but you can do different methods too,
Essentials apparently does it with a Map<String, Enchantment> and it's all coded in a file
But you could also just load that from a text or config file

[limpid veldt]

version: version
main: main of your class. com.dublindevil.dubshop.DubShop
api-version: 1.17
prefix: log prefix like CoolPlugin or DS or smtn
depend: [ ] plugins to depend on
authors: [ your name here ]
description: desc of your plugin

commands:
  createshop:
    permission-message: You do not have permission to execute this command
    permission: dubshop.createshop
    description: Create Sign Shops
    aliases: setshop
    usage: /createshop <price> <quantity> [Warp Name]```

so just import the essX library and get the enchs? that seems like a pretty good option tbh

[eager hinge]

World#rayTraceEntities

rayTraceEntities​(Location start, Vector direction, double maxDistance)

[atomic gyro]

ohhh, once I run that I should run the result?

[eager hinge]

that method returns the result and you can getHitEntity()

[rapid meteor]

What about just the command one?

Like commands:HelloWorld:usage </command>?

[atomic gyro]

Oh, so like this?

[limpid veldt]

wdym

like it shows an example command of createshop there

/createshop

the usage is just what is shown when the commandexecutor returns false

[eager hinge]

do something like
Player.getLocation().getWorld().rayTraceEntities(Player.getLocation(), Player.getEyeLocation().getDirection(), 10)

[rapid meteor]

How do I enable my command via a .yml?

[limpid veldt]

the plugin.yml in a plugin declares the command, you then need to create an executor for it in the main

[atomic gyro]

Where should I put that, though? After the RayTraceResult?

[limpid veldt]

the executor class is called when the command is executed

[rapid meteor]

Yeah I know but how do I control the like prefix.

Like if I were to type /hello

How do I make that valid?

So it says Hello Again!

I know how to do it in Java.

[limpid veldt]

you need a lot more than just a yml to do anything lol

[rapid meteor]

I know how to create the command.

But I don't know how to set a "prefix" for it.

Like so it's valid typing /hello

[eager hinge]

that method returns a result...

RayTraceResult Result = Player.getLocation().getWorld().rayTraceEntities(Player.getLocation(), Player.getEyeLocation().getDirection(), 10);
//then something like 
Entity LookingAt = Result.getHitEntity();

[rapid meteor]

And it would return an result.

[atomic gyro]

OH. I get it now, thank you!

[rapid meteor]

dubz88?

[limpid veldt]

in the onEnable put this to declare the HelloCommand class as the one that handles /hello
this.getCommand("hello").setExecutor(new HelloCommand());

then make a class called HelloCommand and make it implement the CommandExecutor

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
      sender.sendMessage("hello");
      return true;
    }
}

[rapid meteor]

Are you sure about that?

I saw an tutorial.

[limpid veldt]

there are several ways to do it

[eager hinge]

https://tenor.com/view/are-you-sure-john-cena-ru-sure-about-dat-gif-14258954

[rapid meteor]

An it said something like command:
HelloWorld:
usage: </command>

[limpid veldt]

the usage is just shown if the command returns false

[rapid meteor]

Ohhhhhhh

Know I kinda get it.

[atomic gyro]

I got the code to run, but the .getHitEntity() is returning null despite looking at an entity.

Safe to say I'm looking at one.

        Entity LookingAt = Result.getHitEntity();
        
        if(p.hasPermission("laserEyes.use")){
            if(!(LookingAt == null)) {
                p.sendMessage("Target " + LookingAt + " removed.");
                LookingAt.remove();
                return true;
            } else {
                p.sendMessage("Target is unable to be removed.");
                return true;
            }
        } else {
            p.sendMessage("You do not have permission to execute this command!");
        }
        return false;```

this is the code that is acting up

[eager hinge]

what about the distance, try to get as close as possible. I'm not sure if the distance is in blocks 😄

[atomic gyro]

oo good point

[minor garnet]

@atomic gyrotry p.getEyeLocation() else p.getLocation

[atomic gyro]

It was the distance that was the issue.

Had to ram into the mob to remove them.

Is the distance in Pixels or 1 = .1 blocks?

[eager hinge]

whatever
do Double.POSITIVE_INFINITY

that might not work though 😄

[atomic gyro]

Oh yeah, as long as you can see it it should work.

didn't work, it has to be finite. I guess 99999 will cover it.

[spiral bramble]

I'm going to develop a custom plugin for my 1.17.1 server, do I need to use J16?

[eager hinge]

That isn't a number. that might cause the error. Try Double.MAX_VALUE

[atomic gyro]

For some reason, 10 is the only working value.

I tried 100, and Double.MAX_VALUE.

[eager hinge]

these work fine for me

[hybrid spoke]

whats the issue

[atomic gyro]

Trying to set it so that an entity I'm looking at while I run the command is removed.

[hybrid spoke]

and for what the double?

[atomic gyro]

For some reason, the double value on
RayTraceResult Result = p.getLocation().getWorld().rayTraceEntities(p.getLocation(), p.getEyeLocation().getDirection(), 10);
Isn't working

10 worked before, and now is no longer working.

[lost matrix]

1. Naming convention. result
2. How do you determine failure or success?

[atomic gyro]

1. should I change it to lowercase?
2. Failure would be looking at an entity, running the command, and it returning null. Success would be looking at it, running the command, and it disappears.

[lost matrix]

Try starting the ray trace from the players head and not his feet

[lost matrix]

I know that all the youtube tutorial kids think its cool if they use single chars like p and e and still know what they mean but its just very unclean.

[atomic gyro]

I'll change it up next time I make a plugin I guess.

How do I avoid removing myself from the game?

[lost matrix]

You need to use a Predicate so that the ray trace doesnt instantly hit yourself

[hybrid spoke]

entity != you

[atomic gyro]

How would I input a predicate? I'm pretty rusty on my implementation.

[lost matrix]

    final World world = player.getWorld();
    final Location start = player.getEyeLocation();
    final Vector direction = start.getDirection();
    final double distance = 10.0;
    final Predicate<Entity> filter = (hit) -> !hit.equals(player);
    final RayTraceResult result = world.rayTraceEntities(start, direction, distance, filter);

You might also get away with

    final Predicate<Entity> filter = (hit) -> hit != player;

[hybrid spoke]

final final final final final

[lost matrix]

Yes. I like it and thats why i configured my IDE to make everything final on default.

[atomic gyro]

What would (hit) be?

[lost matrix]

hit is the entity that is being hit. This is called a lambda expression.
It takes an entity and returns a boolean (Predicates are defined like that)

[atomic gyro]

so (hit) is the same as .getHitEntity()?

how can you call it before the method finishes?

[grim ice]

isn't that fine? the values won't change either way?

[lost matrix]

You can not call this method yourself. This is a method that you construct. It gets called internally for every entity that is hit.
If the method you passed returns false then the hit entity gets ignored and just proceeds. Its like a filter for when to stop the ray trace.

[atomic gyro]

i am thoroughly confused because this is glowing red like the sun in my IDE and theres no bukkit imports to fix it

[lost matrix]

  final RayTraceResult Result = world.rayTraceEntities(start, direction, 10, this::isViableEntity);
  ...

  private boolean isViableEntity(final Entity entity) {
    // Check if entity is viable
    return true; // Or false
  }

You can also define them like this.
Its basically just a delegate method you pass.

[lost matrix]

Java version, Spigot version?

[atomic gyro]

1.8 / 1.17.1

[lost matrix]

Show your code

Also use Java 16 for 1.17.1

[atomic gyro]

RayTraceResult Result = p.getLocation().getWorld().rayTraceEntities(p.getEyeLocation(), p.getEyeLocation().getDirection(), 10, filter);
Entity LookingAt = Result.getHitEntity();```

oh jeez thats messy

isnt that messy on my side, sorry

[lost matrix]

It gets less messy if you define more variables

is there a difference between ```java

and

Gui obj = new Gui();
obj.open();

[rapid meteor]

Can anyone tell me why my server logs out a message saying my permissions.yml is empty?

[atomic gyro]

its reading that statement as a second double for some reason.

[eager hinge]

no, but you can't do Gui obj = new Gui().open();

[hybrid spoke]

its "fine". literally opinion-based. it doesnt restrict anything. in my opinion its an overuse of final and very messy.

[tardy delta]

oh lol

ah not

ofc

[grim ice]

how

then why use private

[rapid meteor]

Can anyone tell me why my server logs out a message saying my permissions.yml is empty?

thats normal

[hybrid spoke]

you cant compare that with each other

how

[rapid meteor]

No it isn’t.

Cause my plugin won’t come on then

[grim ice]

they both won't stop ur code from working in most cases but they should be used

[tardy delta]

oh

use vault?

[hybrid spoke]

once you get into api design you will understand it

[grim ice]

well

explain it at least lol

[hybrid spoke]

private is important. final is too, but not for local vars.

[grim ice]

hmm

[atomic gyro]

For some reason, p.getWorld() doesn't work.

[hybrid spoke]

private is used to have something "class-only". important for encapsulation. final is used to declare something as "will not change anymore" what is not necressary for local vars in most cases.

[tardy delta]

p.getLoc.getworld

[atomic gyro]

Still doesn't work.

[tardy delta]

what does it say

[atomic gyro]

It's saying there's a type mismatch and that it can't convert org.bukkit.World to the MC version of .world.

Type mismatch: cannot convert from org.bukkit.World to net.minecraft.world.level.World

[tardy delta]

are you using org.bukkit.World?

[atomic gyro]

It autoreplaced my org.bukkit.World with the second one when I imported. Sorry.

[tardy delta]

start in in the player mount event or something?

[eager hinge]

300 ticks isn't 30 seconds

[violet depot]

sorry its 600ticks or 30sec

[eager hinge]

you need to create a global variable for the taskID, create the task, save the id of it to the variable. And on PlayerMountEntityEvent Cancel Task with that ID
Also check if it's been 30 seconds, and don't do it. Clear for next time.

You could put the taskIDs to a HashMap. so each player can do that at the same time

[tardy delta]

Bukkit.cancellTask()

biem

ah shit no

[violet depot]

Does canceled delayed task will start again whenever a player activates the delayed task?

[tardy delta]

Bukkit.getScheduler().cancelTask(pid);

can someone tell me why this doesn't work?

It's saying result can't be resolved.

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

if you don't understand what conclure said

I understand what he wrote, not how to implement it.

[grim ice]

I'm not gonna claim I know java well but I understand it enough.

[ivory sleet]

OkaKnight thing is

[opal epoch]

I created an abstract class..
i want that other developers who are not able to see my code write addons wich depends on my abstract class...

[grim ice]

what conclure said is 10 minutes of java

[ivory sleet]

A variable only lives inside the
{

}
It’s declared in usually

[tardy delta]

thats what dependencies are

[ivory sleet]

if you have something like this:
{
Object result;
}
result.method();
at line 4 variable result becomes unreachable

[tardy delta]

is you assume other devs dont use a decompiler then they cant read it

[ivory sleet]

So a good way to handle it is to move the result.method() part to line 3, whilst } comes at lines 4 instead
