yes use onCommand in replace of your execute

stark marlin
#

Might just put the tab executor in the main class then I guess

eternal oxide
#

its just a method name change

#

same args

#

then in yoru main register the Command Executor

lost matrix
#

Do you know what a Set is?

crimson terrace
#

how do I get something akin to a hashmap that allows duplicate keys?

eternal oxide
#

You can;t have duplicate keys

#

unless its a List

halcyon mica
#

@lost matrix Removing craftmob from the spigot entity did not change it, neither did removing bukkit mob from the interface

kindred valley
crimson terrace
#

so I need an actual list for duplicate keys?

eternal oxide
#

duplicate entries

#

the whole point of a keySet is that a single key references one value

#

if you want to store multiple objects under that key you can

#

but you use one key

crimson terrace
#

meh, might just use the Location as a key and the uuid as a value

#

works all the same, just cant read it as well from the file

eternal oxide
#

what are you trying to do?

crimson terrace
#

Im making a plugin so you can lock chests and they cant blow up. im trying to limit the amount of chests a player can lock

eternal oxide
#

use Block not location for a start

crimson terrace
#

fair

eternal oxide
#

then store as Map<UUID, Set<Block>>

crimson terrace
#

didnt think of that, thanks 😄

lost matrix
crimson terrace
#

might just use a list as the second one

halcyon mica
#

Which one

#

lmao

eternal oxide
#

List you can mess up as it allows duplicates, Set doesn;t

#

however, Blocks are unique, so

crimson terrace
#

I trust my code not to mess up so it wouldnt add duplicate blocks

lost matrix
dense goblet
#

have a block position class and override its hash and equals methods

#

then use that in a set

halcyon mica
#

I implemented it everywhere

#

No change

dense goblet
#

if you make it immutable then you get a small performance boost too in some situations afaik

crimson terrace
#

im not trynna make it complicated

For curiosity, is there a neat event that detects when cobblestone is generated from flowing lava and water?

#

Yes

i think its bugged tho

hello i'm asking about how to add tags for players like this

I just copied the plugin extension from the blog post for 1.17

#

Didn't mess with it

dense goblet
lost matrix
# halcyon mica I do, yes

Try not to. This means your plugin would only run with a moj mapped jar for once but the error could be in there
as Pose might be resolved weirdly

halcyon mica
#

Hm

#

In that case I do not reobfuscate it

lost matrix
#

Just to rule it out

halcyon mica
#

Because it works with a bog-standard spigot jar

lost matrix
#

I mean if you dont re-obfuscate it. Then it will only run with a mapped jar.

halcyon mica
#

right

lost matrix
#

Try removing the remap goal and see if it compiles without it

halcyon mica
#

Nope

#

No change

#

What wonders me is why the error is apperantly caught in the interface

#

Not the spigot entity or the nms one

#

But it just points to the beginning of the file

#

Ok, I have narrowed it down

#

When I stub the Interface, it works

lost matrix
#

Like a mock impl

halcyon mica
#

Yes, the pathfinder interface

#

And by stub, I mean comment out the entire body of the interface

#

Do note, the mob extension remains

lost matrix
#

Did your Pathfinder import nms Pose?

halcyon mica
#

Nope

#

Infact, the only nms stuff stuff it imports is PathNavigation and Path

#

Which is unrelated to poses

lost matrix
#

Did you try commenting out methods?

does anyone that knows citizensapi know why this error is happening?

the error happens here:

I heard that it's because citizens needs to fully load first, but i have it as a dependency in my plugin.yml ([WorldGuard, LuckPerms, ProtocolLib, Citizens]) and i even put a scheduler around the line that i register the event (which apparently waits until the first tick of the server to run)

Simplest way would be to just save them to disk and read them from there.
But here is a simple approach to getting the String from a json stream.

  private final Gson gson = new GsonBuilder().disableHtmlEscaping().create();

  public String toJson(final InputStream inputStream) {
    try (final InputStreamReader reader = new InputStreamReader(inputStream)) {
      final JsonObject jsonObject = this.gson.fromJson(reader, JsonObject.class);
      return jsonObject.toString();
    } catch (final IOException e) {
      e.printStackTrace();
      return null;
    }
  }
atomic gyro
#

How would I be getting the information as a Stream? Do I call it using the NamespacedKey?

lost matrix
# 
  @Override
  public void onEnable() {
    InputStream isr = this.getResource("theFile.json");
  }
#

Just make sure to not let the stream hanging

atomic gyro
#

This is my first time really using streams, so I have no idea what that means.

lost matrix
#

Use it right away.

atomic gyro
#

Ah ok, it'll be getting used moments after the call. Thanks for the heads up.

#

Is there a means of using the NamespacedKey functions to get the file name as a .json file? So far I've been able to get minecraft:entities/mobname but I don't know what I'd do from there.

lost matrix
#

Wait. You want to get those json files from your own jar, right?

Any reason why you dont want to use the loot table API from spigot?

atomic gyro
#

The loot table API doesn't seem to have any means of accessing the weight, min/max, or special lore about the items.

eternal oxide
#

The API will not allow you to list items and weights

atomic gyro
#

Loot Table API seems to just be for filling chests.

why do you want to do that

just wondering

Is there a way to teleport someone without effecting their momentum? Like can I just move somebody up 0.3 blocks and have their motion remain the same

left swift
ivory sleet
#

Yeah

#

Might be the case it got removed

left swift
#

ok, i check this

ivory sleet
#

Like the normal teleport method

dusty sphinx
#

Actually i think I might've said the wrong thing

#

It keeps momentum

#

But like if a player is pressing W, they only start moving in the air which obviously means they don't have the same momentum

ivory sleet
#

What about getting their velocity before and applying it after the teleport?

dusty sphinx
#

Doesn't make a difference

#

Like if someone is pressed up against a wall holding foward and they get teleported i want them to move foward

#

So is there a way to check if a player is holding foward?

#

Don’t think

Hey can any1 help me please? Im trying to create a random class chooser. Im trying to create a minecraft manhunt minigame and am trying to create a randomizer on who is the speedrunner and make everyone else the hunter.

lavish hemlock
#

You can use Java's Random class to return a random integer between 0 and 1, and then iterate through each player, if Random returns 1, then you make that player the speedrunner and everyone else the hunter.

solemn gulch
#

there are better ways more efficient

get a list of all the players select a random user from the list using javas random class assign that player to be the speedrunner and then everyone else can be hunters

lavish hemlock
#

in that case

#

You can generate between 0 and the last index of the List (players.size - 1 I think?), then just players.get(myRandomInt)

quaint mantle
#

ok

you want the size not the last index otherwise some poor player won’t ever get to be the runner lol

lavish hemlock
#

reminds me of my Murderer chances on Murder Mystery tho lmao

quaint mantle
#

Slight problem tho

#

Ive never created a plugin before

solemn gulch
#

i would start off with something simpler than hunter vs speedrunner if its ur first time
just try making fun commands and some event listeners that do wacky things so you can get a grip of how to make them

#

then once you are ready apply all the knowledge to create an event like hunter vs speedrunner

lavish hemlock
solemn gulch
#

it deff is one of the easier ones but if u havent done anything before its probably best not to do any gamemodes as a first plugin

lavish hemlock
#

I guess that's fair

solemn gulch
#

i mean it depends how you learn really

#

but you shouldnt expect us to spoonfeed you all the answers

#

or code anything for you

If I have added a command by altering the command map directly by code, is it still possible to set a tab completer for the command? I tried to do it by getCommand().setTabCompleter() but that just caused NPE

Hey guys. I've been trying to make an ability that involves shooting out an item from the player as if they had dropped it, but multiplying its velocity to increase its speed. However, no matter what approach I take to the situation, the item almost always seems like it's shooting out from the center of the player...
Here's a video of the item launching aspect in action:

#

Here's the code used to drop the item (in its current state):JAVA Item droppedItem = player.getWorld().dropItem(player.getLocation(), item); Location eyeLoc = player.getEyeLocation(); droppedItem.setVelocity(eyeLoc.getDirection().normalize().multiply(0.7));

#

OHHH

#

whoops

#

lmao

#

should move the eyeLoc line up so I can use it in the spawn line as well though

hasty prawn
#

Yes

round python
#

so so far I made it so you could mount dolphins underwater and that my custom dolphins replace regular ones

#

but

#

slight problem

#

how do I make the player control it

woeful crescent
#

set the dolphin's direction to the player's direction?

#

Maybe?

#

try it

#

could be an easy fix

#

You would also have to set the dolphin's yaw and pitch to the player's yaw and pitch

round python
#

how would I do that?

woeful crescent
#

You would utilize the Location#setDirection and Location#getDirection methods in order to get and set directions

#

For yaw and pitch, you would want to use Location#getYaw and Location#getPitch

round python
#

ohh ok tysm

woeful crescent
#

I know yaw and pitch might sound complicated if you don't know what it is yet, but it's really just two rotational factors

#

Sorry, but I need to leave now, so if that quick solution doesn't succeed, you'll have to work out another one on your own.

round python
#

yeah its like the yaw and pitch of a plane right

#

also yeah np

#

ty for your help

woeful crescent
#

Pretty sure it's the two rotational axis

#

Cya

round python
#

so might dolphin replacing thing is quite janky so how would I make it so that dolphins are replaced with my dolphin

SQLite statement

ALTER TABLE players RENAME TO old_players

apparently returns a query?

PreparedStatement ps = c.prepareStatement("ALTER TABLE players RENAME TO old_players");
ps.executeUpdate();

[12:26:51 WARN]: java.sql.SQLException: Query returns results

#

But for the MySQL connection it is fine, it doesn't error. Is the fault on my end or on the jdbc itself?

Oh that's just a sample. I have it named something else completely

Currently have the workaround if (m.version.equalsIgnoreCase("sqlite")) ps.executeQuery(); else ps.executeUpdate();, it works, but I'm not confident about it, plus it looks ugly

syntax looks fine, you don't need the TO there but not sure if that would do shit

Well if another plugin is hard referencing let’s say, your CachedUserManager, then it might not get gcd and instead a leak might be the case

# manic furnace I tried that but when i out print the thread it is the server thread

This is how you start a new async task per player when he joins.
When the player leaves you need to stop the task again.
TrackerTask has to be your own Runnable implementation.

public class PlayerLocationLogListener implements Listener {

  private final JavaPlugin plugin;
  private final Map<Player, BukkitTask> playerBukkitTaskMap = new HashMap<>();

  public PlayerLocationLogListener(final JavaPlugin plugin) {
    this.plugin = plugin;
  }

  @EventHandler
  public void onJoin(final PlayerJoinEvent event) {
    final Player player = event.getPlayer();
    final TrackerTask trackerTask = new TrackerTask(player);
    final BukkitTask bukkitTask = Bukkit.getScheduler().runTaskTimerAsynchronously(this.plugin, trackerTask, 0, 600);
    this.playerBukkitTaskMap.put(player, bukkitTask);
  }

    final Player player = event.getPlayer();
    final BukkitTask bukkitTask = this.playerBukkitTaskMap.remove(player);

i would do a global task

quaint mantle
#

🥄

golden turret
#

with a simple object or map to store the last storage

lost matrix
golden turret
#

why

#

😔

lost matrix
#

Idk

#

I think he hasnt done much with tasks so far. Which is totally ok.

stone sinew
#

task per player is probs safer anyways. That way if he gets to many players the tasks are spread out

lost matrix
#

They are async anyways.

#

So wouldnt matter.

How do i make a paper-spigot plugin in 1.8.8?

golden turret
#

use spigot as base

#

hope i helped 👍

lost matrix
golden turret
#

let they use 1.8

#

you can run both client and server with only 512mb of ram

lost matrix
#

I want the API to not be forced to support versions that are older than the people using it.

quaint mantle
#

But then how would i make my server run on 1.8? if i cant use 1.8 to code?

eternal night
quaint mantle
#

ye but i kinda also want the 1.8 pvp and all the plugins that exist for that are very buggy

eternal night
#

allows you to run the latest server software but people from older versions may still connect

golden turret
eternal night
#

they are?

there is a lot of threads about that

quaint mantle

quaint mantle
#

thats not a plugin link :D

lost matrix
# quaint mantle Do u have any?

Anyways. If you really want to code with old buggy software:
You need to add the spigot API as a dependency to your project.
Do you use maven?

quaint mantle
#

yes

#

But its fine ill use viabackwards !

lost matrix
#

Then try running BuildTools with the 1.8.8 as target to install it into your local maven repo.

vague oracle
#

It makes no sense why people prefer 1.8 pvp, 1.17 pvp is perfectly fine if you know how to do it, but 1.8 pvpers dont so they stick to 1.8. IMO there is more of a skill gap with 1.17 pvp.

atomic gyro
#

i like 1.8 pvp because its just better

vague oracle
#

How?

lost matrix
vague oracle
#

its perspective

atomic gyro
#

1.17 pvp has cooldowns so you cant do any of the cool stuff you could do before, like combos/strafe hit

vague oracle
atomic gyro
#

while i like 1.17 pvp, it lost all the cool parts and became a hit n run fest with axe crits and shields

#

theyre both good, in different ways

#

1.8 for fast paced skill heavy combat and 1.17 for slow paced tactile combat

vague oracle
#

I do myself not like shields, but what you can do is lower the damage for all weapons, remove shields and remove the hit cooldown. This edited version of 1.17 pvp is very fun.

#

no 1.8 is not skill heavy

atomic gyro
vague oracle
#

its who can click faster

atomic gyro
#

no its definitely not

vague oracle
#

it is you click faster you hit them first

atomic gyro
#

i can click 10/s and lose to my friends that click like 6/s

#

its strafing, positioning, and combos

vague oracle
#

then you have bad aim, but bad aim will make you lose in both 1.17 and 1.8 so it doesn't really mastter

atomic gyro
#

you want to get out of the way of their cursor, keep them in your cursor, and crit them while moving forward

#

if you drop them at any point you're getting hit back

#

anyways, I'm having an issue finding a file. Any reason why this is coming back with an exception?

File file = new File(player.getWorld().getWorldFolder(), "data" + File.separator + "minecraft" + File.separator + "loot_tables"
        + File.separator + "entities" + File.separator + "zombie" + ".json");```
This should be a file that exists.
#

data/minecraft/loot_tables/entities/zombie.json is the target file.

vague oracle
#

Don't know much but don't you only need 1 argument.

atomic gyro
#

What do you mean, as in I'd only need zombie.json?

quaint mantle
#

this is my error once i try build my 1.17.2 plugin

#

#

this too

lost matrix
paper viper
#

iirc you don't need the file separators

worldly ingot
quaint mantle
#

/

paper viper
#

you can just turn them into forward slashes and java should already convert

worldly ingot
#

And yes, you're right. Forward slashes

atomic gyro
#

just realized that getWorldFolder is going to, coincidentally, get the world folder and not the .jar. Back to drawing board.

lavish hemlock
paper viper
#

Yeah i wanted to say to use Path

#

but idk ppl would run me down

#

lol

lavish hemlock
#

it's legitimately the better API

#

both in usability and performance

paper viper
#

yeah immutable strings

atomic gyro
#

Since so many people are here, how do I get to the minecraft.jar? Haven't been able to find a way to call it using Spigot yet.

paper viper
#

wdym

lavish hemlock
atomic gyro
# paper viper wdym

I want to call files that exist inside the minecraft.jar. Like data/minecraft/loot_tables/entities/zombie.json for example.

lavish hemlock
paper viper
#

^

#

and you have no idea where it could be installed as it can vary anyway

#

and not all servers have clients installed

#

in fact most servers dont

#

lol

atomic gyro
#

Just realized then, should I just make a datapack using the file function that has every default loot table in game, then I can access them whenever and it gets replaced from default?

lavish hemlock
#

that would get messy pretty quickly

#

besides, I believe datapacks are loaded on the server?

worldly ingot
#

They are

golden turret
quaint mantle
golden turret
#

change it in project settings

quaint mantle
#

is it the sdk version?

lavish hemlock
#

yeah

golden turret
#

right there

unknown.png
quaint mantle
#

which one should it be?

#

what version

golden turret
#

java 16

quaint mantle
#

got it

golden turret
#

minecraft 1.17+ now requires java 16

lavish hemlock
# worldly ingot They are

in that case, the server has access to datapacks.
I'm unsure if it's possible to programmatically modify a loaded datapack (my knowledge of the API is limited) but there's better ways than rewriting all of the default datapacks lmao @atomic gyro

atomic gyro
#

Yeah this has gotten a bit confusing.

tardy delta
#

whats the best way?

for (account a : accounts) {
  if (a.name() != name) continue;
}
return a;

or

for (account a : accounts) {
  if (a.name() == name) return a;
}
lavish hemlock
#

the second

golden turret
#

2

atomic gyro
#

I'm more or less just trying to get the data inside a loot table as a string so I can use it, but considering I'd need to either recreate it in a datapack or find a way into a file I can't access, I'm gonna have to go back to the drawing board.

lavish hemlock
#

the first would loop through the entirety of the list

tardy delta
#

i'm wondering why people actually use it then

lavish hemlock
#

oh and also

#

the first is just plain invalid semantically

#

as a doesn't exist outside of the scope of the for loop

tardy delta
#

its just an example

lavish hemlock
#

aaaand you should probably use .equals when comparing strings and objects in-general

tardy delta
#

iknow 🥺

lavish hemlock
quaint mantle
#

Should i use plugman to reload only my plugin not the server?

stone sinew
quaint mantle
#

something else then?

lavish hemlock
#

I used a plugin kinda like it once

#

forgot what it was called tho

#

it worked pretty well

stone sinew
quaint mantle
#

i have like 3 plugins, its a private server i dont think restarting is rlly needed

tardy delta
#

cant i return something in a lambda expression?

lavish hemlock
#

if it's a Function then it has the ability to return

#

(or if it's a Supplier)

stone sinew
lavish hemlock
#

but something like Consumer can't

tardy delta
#

in this context

unknown.png
quiet ice
#

Just beware that sometimes stuff works with reloads but borks on restarts

tardy delta
#

ah its a consumer

lavish hemlock
#

yeah, forEach is a Consumer<T>

#

you can't use a lambda here

#

bc you can't get the account out of the lambda scope due to effectively-final/final rules

quiet ice
#

you can never return a method inside a lambda

quaint mantle
#

i have a decent plugin manager its fine

quiet ice
#

A lambda is effectively an anonymous class

lavish hemlock
#

but I'm unsure, it generates the InnerClasses attribute on a class with a lambda so I assume so.

quiet ice
#

nope, it's a method internally

#

method + methodHandle

lavish hemlock
#

I'm curious as to see why it generates InnerClasses then, lemme look at the JVMS

quiet ice
#

well, a class is created at runtime. but that is not visible in the bytecode

lavish hemlock
#

hmmmm seems it's hard to find information on lambdas from the JVMS

#

oh lmao

firefox_bLqcCwkV63.png
#

that is comedic

#

so yeah

#

a lambda is only effectively an anonymous class, u right

round python
#

How would I replace a specific entity with my own custom one?

quaint mantle
#

quick question, does the index of getWorld from getServer go 0: overworld, 1: nether, and 2: end?

quiet ice
#

remove the entity from the game and spawn your custom one at the same location

round python
#

Would I use entity spawn event?

#

Like it would check for that specific entity using instance of that specific entity, then it removes it

#

Then it spawns in mine right

#

Problem is my class extends that specific entity and instanceof includes subclasses so should I make an object of that specific entity and check for whether the event.getEntity equals that specific entity?

quiet ice
#

obj.getClass() exists

round python
#

Oh ok I’ll just use that then thanks

#

Appreciate it

upbeat ice
#

Anyone know how many decimal places a Java program double will solve before rounding

#

Pls ping me if you respond

quaint mantle
#

Worlds.get(0, 1, and 2) would return the Overworld, Nether, and End respectively right?

eternal oxide
#

yes

#

probably

#

depends on what is enabled in what order, but 0 is always overworld

worldly ingot
#

You'll never have a guarantee of that

#

Even world_the_end and world_nether aren't guaranteed

eternal oxide
#

Lets just say no guarantees, but I've never seen an occurrence where 0 wasn't overworld, even after many reloads

quaint mantle
#

on what is enabled?

#

hmm actually i could work with that, thanks for the help

rapid meteor
#

Bois why do my plugin.yml say that permission.yml is empty?

eternal oxide
#

I'm pretty sure it doesn't say that

rapid meteor
#

I mean it says permissions.yml is empty ignoring it.

worldly ingot
#

That's a message from Bukkit. You can ignore that lol

rapid meteor
#

Why doesn't my plugin work then?

rapid meteor
worldly ingot
#

If your plugin isn't starting it's for some other reason. Let's see your full server log

tardy delta
#

whats the best way of making a yaml file? putting a default one in the jar or creating one yourself on enable?

eternal oxide
#

If you want comments, put one in the jar

worldly ingot
#

Depends on the situation but generally speaking it's much easier to just have a regular file you can copy

#

Having to write it out in a more verbose manor just doesn't make sense ;p

tardy delta
#

new HashMap<>(theOtherMap);

austere cove
#

yo what's the point of the bitmask @ #getAsInt()

LargeFireball fireballprojectile = player.launchProjectile(LargeFireball.class);
                        fireballprojectile.setVelocity(fireballprojectile.getVelocity().multiply(1.5));
                        fireballprojectile.setIsIncendiary(false);
                        fireballprojectile.setFireTicks(0);
                        fireballprojectile.setShooter(player);

How can i make this break blocks?

woeful crescent
#

Why are you trying to iterate through a HashMap?

#

Can I see the error?

silver shuttle
#

Is there a way to cancel a player right clicking? So say I want him to be able to right click once and not hold it, so he has to continuously click?

eternal oxide
#

<ItemStack>

tardy delta
#

:/

eternal oxide
#

or do it properly and synchronize

#

oh CME, yeah, clone

vague oracle
#

you need to use keySet() or values()

eternal oxide
#

or add all the items you want to remove and remove them after

#

or use an iterator, then you can remove

woeful crescent
#

Anyone know if Damageable#damage(dmg, source) calls EntityDamageByEntityEvent?

eternal oxide
#

an Iterator is teh correct approach.

vague oracle
waxen plinth
#

Consider naming your variables descriptively

woeful crescent
eternal oxide
#

yes, but its not a good idea

waxen plinth
#

Wouldn't that effectively clone every time

#

What is getBingoItems returning

#

Bruh

#

Why are you creating a new one

#

Why

quaint mantle
#

?

eternal oxide
#

You just need to handle your data safely

waxen plinth
#

My god

#

You don't need to clone the entire map for that

woeful crescent
#

Just don't use an enhanced for loop?

waxen plinth
#

And it won't even prevent CME

eternal oxide
#

with an iterator you can safely remove elements without cloning anything

waxen plinth
#

Use a regular for loop and just do list.remove(i); i--;

#

Iterator is also a good solution

eternal night
#

removeIf is also cute

waxen plinth
#

If you're not doing anything but removing specific elements (or if you are removing multiple) use removeIf

waxen plinth
eternal night
#

tbf yours has more info xD

ugh can i put an message with a ' in a yml string?
