[elfin pilot]

spawn an Item with something like Item i = world.spawn(location, Item.class) and i.setItemStack(itemStack);

not sure if thats the exact syntax but its pretty close

[sly trout]

thank you very much I found world.dropItem

[elfin pilot]

nice :D

[flint coyote]

Are there any rules that state whether I'm allowed to track which active servers have my plugin that gets published on spigotmc installed?
Like save the server ip and port (since it's unique) and amount of current players that refreshes every hour?
I'd be interested in statistics like that when releasing more plugins.

I saw some premium resources have graphs on their resource page - so I wanna know whether there's any kind of limitation to what data I'm allowed to collect

[delicate lynx]

it would be kinda weird as a server owner

bstats does this but keeps it anonymized

[flint coyote]

I thought about anonymizing it. The problem is I still need a "unique key" per server. I would say hashing the ip does the job. But since an ip is 32 bit it can easily be bruteforced and "unhashed". Any idea on how to actually keep it anonymized without mixing up data from different servers?

Or in other words: How does bstats do it?

[delicate lynx]

bstats generated a UUID for each server I believe

[brave sparrow]

you could hash the string of the IP instead of the IP itself

[flint coyote]

does it do that by unique details about the server or is it simply doing #randomUUID() and storing it somewhere?

[delicate lynx]

not sure, but it saves it into plugins/bStats/config.yml

it probably generates a random one I would assume

[flint coyote]

can you elaborate what you mean by that? From what I understand I could still form all possible ip strings and hash them in a matter of minutes (or probably hours but it wouldn't take long)

[flint coyote]

Yeah if it saves it then it's probably a random one. Guess I can do that, too. If the server owner decides to delete that file I'll have some messed up data but I guess for the sake of keeping data anonymous that's worth it

[brave sparrow]

You could use some kind of salt/pepper to avoid having the same IP produce the same hash

You could make the salt the hash of the main world UUID

[flint coyote]

That idea also isn't bad. I probably won't use the worlds name since that's 90% "world" but I can probably find something that is more unique. Maybe the seed of the world

[brave sparrow]

The world UUID

Not the name

But yeah seed would work too

[flint coyote]

Oh worlds have a uuid? Didn't know. That's great for hashing. Guess I'll do it that way. Thanks a lot!

[brave sparrow]

👍

The world UUID is also more unique than seed

You could in theory do something with the UUID of all the loaded worlds

So that way even if they download a map for the overworld, nether and end would probably be different

[flint coyote]

But there's still enough possible seeds that I don't have a way to salt every possible ip with all seeds in a reasonable time. But I think UUID is the better choice

[brave sparrow]

Yeah

Also it’s important to note that your plugin has to still work if your backend metrics server goes down

[flint coyote]

yeah I mean if they swap out a map it will look like a new server. But I can't prevent that without storing it somewhere on the server

[brave sparrow]

Yeah that’s the downside with a somewhat ephemeral fingerprint

[flint coyote]

ofc. I will keep everything async, won't do it too often and will obviously let it fail silently

[flint coyote]

There isn't an optimal solution. But I'll think about which of the more or less optimal ones I will take. I really don't need to know which server has my plugin. I just wanna know "how it is used", if that makes sense

[uneven barn]

Am I allowed to ask questions about coding plugins here or is this channel only for developing the spigot/bungeecord framework itself?

[flint coyote]

Feel free to ask anything about coding Plugins. That's what the channel is made for

[brave sparrow]

It’s for questions about coding plugins

[brave sparrow]

You could store the hashed value in the config and do error correction on it

So if they modify the fingerprint in the config for whatever reason, you can perform the fingerprint algorithm again and figure out if the change was caused by a world UUID shifting or just randomly editing the key

Since the IP:port would still be the same

All depends on how much you care that the fingerprint is accurate

[flint coyote]

Since I don't know the old fingerprint after they changed it in the config I can't really determine why it changed. I can only recognize that it doesn't match the one from the fingerprint algorithm for whatever reason

(unless it was changed while the server was running but I don't have to read it multiple times during runtime anyway)

Noticing that it changed (for any reason) gives me the possibility to set a flag inside the database that it might be innacurate atleast. Might implement that aswell

[uneven barn]

@EventHandler public void onMove(PlayerMoveEvent e) { Block fromB = e.getFrom().getBlock(); Block toB = e.getTo().getBlock(); if (fromB == toB) return; Player pla = e.getPlayer(); //rand is a number generator if (rand != null) { if (rand.nextFloat() < 0.1) { pla.sendMessage(fromB.toString()); pla.sendMessage("To:"); pla.sendMessage(toB.toString()); } } } for some reason the messages are sent even when I don't really change the Block my Location is at

[flint coyote]

don't compare objects with ==
You have to use .equals() instead

[uneven barn]

(did i format the code correctly on discord?)

[flint coyote]

in other words:
change
if(fromB==toB)
to
if(fromB.equals(toB))

[hardy swan]

unless comparisons with enum constants

[hasty prawn]

You should probably use ```java in the future.

[tidal hollow]

I want to make certain effects when using a totem

this is my code but it doesn't work :(

@EventHandler
    public void totemMessage(EntityResurrectEvent event) {
        if (event.getEntity() instanceof Player) {
            Player player = (Player) event.getEntity();
            if (player.getInventory().getItemInMainHand().getType() == Material.TOTEM_OF_UNDYING || player.getInventory().getItemInOffHand().getType() == Material.TOTEM_OF_UNDYING) {
                for (Player all : Bukkit.getOnlinePlayers()) {
                    all.sendMessage(ChatColor.GRAY + "¡El Jugador " + ChatColor.DARK_AQUA + "" + ChatColor.BOLD + player.getName() + ChatColor.GRAY + " ha consumido un tótem!.);
player.addPotionEffect(new PotionEffect(PotionEffectType.POISON, 300, 1));

[hexed hatch]

This occurs on the entity resurrect event

which is after the player consumes a totem and it saves their life, right?

If I'm right about that, why would you be checking their inventory for a totem that is already gone?

[tidal hollow]

I'm stupid

😢

[hexed hatch]

I might be wrong

and looking at the docs, it appears I just might be

I would recommend putting some debug lines before and after every if statement to see how far it gets

[brave sparrow]

You can compare what’s in the config to a newly generated fingerprint at runtime and use that with some error correction to figure out if the world UUID changed or if the whole thing is scuffed up

[tender shard]

you're right

no need to check for the totem, it was already removed

unless the event is cancelled

[hasty prawn]

The totem will still be in their hand when the event is fired.

[tender shard]

hm but then their code should work

anyway, there is still no need to check for the totem. it's enough to check whether the event is cancelled

[hexed hatch]

Called when an entity dies and may have the opportunity to be resurrected. Will be called in a cancelled state if the entity does not have a totem equipped.

This is interesting phrasing

[hasty prawn]

You're calling that method right

Send the command class

Hm, add some print statements and see where it's not reaching.

That's fine

Where'd you put it

[uneven barn]

The java doc for that method seems to imply that those are the same. Did that get overridden in spigot or bukkit?

[lavish hemlock]

^ this applies to strings too btw

And uh UUIDs

It does not apply to enums since enums are static and therefore only have one memory location

[uneven barn]

https://docs.oracle.com/javase/8/docs/api/java/lang/Object.html#equals-java.lang.Object-
this method returns true if and only if x and y refer to the same object (x == y has the value true).
Could you give me your link? This one was the one I was using

[lavish hemlock]

That's referring to the default implementation

By default, equals is the same as ==. Classes must implement it themselves.

[uneven barn]

That kind of thing is hard to tell since I've only been looking through the docs

[lavish hemlock]

The stdlib's javadocs are more

intelligent than understandable

ig it's fair

They pack a lot of precise information

(Just not easy for newcomers to read, imo, although most of the time I fail to understand programming docs bc of their big words)

[idle kindle]

hello, I am writing a plugin to add functionality with boilers to dispensers, I need help because when a redstone is supplied to a dispenser, the item is not removed, it is thrown out of it and I don’t understand how to solve it

public class EventsList implements Listener {
@EventHandler
public void Cauldron(BlockDispenseEvent e){
Block dispenser = e.getBlock();
BlockState blockstate = dispenser.getState();

    Dispenser dis = (Dispenser) blockstate;

    Inventory inv = ((Dispenser) blockstate).getSnapshotInventory();
    if(dispenser.getBlockData() instanceof Directional){
        Directional dir = (Directional) dispenser.getBlockData();
        Boolean flag_lava = Boolean.FALSE;
        Boolean flag_water = Boolean.FALSE;
        Boolean flag_empty_lava = Boolean.FALSE;
        Boolean flag_empty_water = Boolean.FALSE;

        if(dispenser.getRelative(dir.getFacing()).getType().equals(Material.CAULDRON)){
            ItemStack item = new ItemStack(Material.LAVA_BUCKET);
            for (int i =0; i < inv.getContents().length; i++) {
                if (!inv.contains(item)) {
                    //flag_lava = TRUE;
                    inv.remove(Material.LAVA_BUCKET);
                    inv.addItem(new ItemStack(Material.BUCKET));
                    blockstate.update();
                    dispenser.getRelative(dir.getFacing()).setType(Material.LAVA_CAULDRON);
                    break;
                }
            }
        }

[terse lily]

if you don't need item to be thrown out (need the event to be cancelled), put e.setCancelled(true); somewhere

also why are you using Boolean object type instead of primitive boolean

[idle kindle]

ok

thank

[silver shuttle]

When making a set method for an integer in a specific range for a custom object, is it better to throw an exception if the integer is out of bounds or to simply adjust the integer?

e.g.:

// Throwing an exception:
public void setUses(int uses) throws IntegerOutOfBoundsException {
  if(uses < 1 || uses > 1000) {
    throw IntegerOutOfBoundsExcetion;
    return;
  }
  maxUses = uses;
}

// Adjusting the value
public void setUses(int uses) {
  if(uses < 1) {
    uses = 1;
  }
  else if(uses > 1000) {
    uses = 1000;
  }
  maxUses = uses;
}

[chrome beacon]

I believe an exeption is the correct way

[silver shuttle]

alright, thanks

How many items can fit into an itemstack?

[tall dragon]

um, normally 64

[tall dragon]

this question really depends on the use case.

[dull whale]

I have a client side entity, how do I listen when its clicked?

[earnest forum]

depends on the material @silver shuttle

[quasi flint]

listen for packets the client sends

[earnest forum]

eggs hold 16, a bed can only hold 1

etc

[silver shuttle]

I am pretty sure it is changeable, yet I cannot find any info on how to.
There is a plugin called StackableItems which allows for any item to be stacked to any amounts, even unstackable items

[quasi flint]

either protocollib, packet events or just ur own packet injector

[tall dragon]

yea. but i don't think this is done with api methods

[quasi flint]

asm , asm , asm , asm (yoke tho)

[silver shuttle]

mmmmmmmmmmmm

ugh

Wish there was an easy way like "ItemStack.setSize()"

[tall dragon]

yea i wish alot of thing too about minecraft

[quasi flint]

just write ur own server software

[earnest forum]

there is something like that no?

[tall dragon]

still does not make everything possible. because certain things are handled client side

[quasi flint]

write ur own client

[tall dragon]

:D

[quasi flint]

we kinda got some server things to already work

lemme grab the github link

[quasi flint]

https://steamwar.de/devlabs/zOnlyKroks/LecternServer

[tall dragon]

this ur own server software?

[quasi flint]

wip but yes

we currently generating the 1.8 to 1.18 classes from json to kotlin files

so build in multiversion support

[tall dragon]

interesting

[quasi flint]

the protocollscraper.kt generates rounda bout 500 classes

if i recall correctly

the funniest thing is, to get native bukkit plugins to run on that piece of garbage

[idle kindle]

if(dispenser.getRelative(dir.getFacing()).getType().equals(Material.WATER_CAULDRON)){
ItemStack item = new ItemStack(Material.BUCKET);
for (int i =0; i < inv.getContents().length; i++) {
if (!inv.contains(item)) {
//flag_empty_water = TRUE;
inv.remove(Material.BUCKET);
blockstate.update();
inv.addItem(new ItemStack(Material.WATER_BUCKET));
blockstate.update();
dispenser.getRelative(dir.getFacing()).setType(Material.WATER_CAULDRON);
e.setCancelled(TRUE);
break;
}
}
}

item dont remove

[tall dragon]

please format it

[idle kindle]

how

[tall dragon]

put 3 of these ` on each side of your code

[idle kindle]

                ItemStack item = new ItemStack(Material.BUCKET);
                for (int i =0; i < inv.getContents().length; i++) {
                    if (!inv.contains(item)) {
                        //flag_empty_water = TRUE;
                        inv.remove(Material.BUCKET);
                        blockstate.update();
                        inv.addItem(new ItemStack(Material.WATER_BUCKET));
                        blockstate.update();
                        dispenser.getRelative(dir.getFacing()).setType(Material.WATER_CAULDRON);
                        e.setCancelled(TRUE);
                        break;
                    }
                }
            }```

[tall dragon]

so now whats it supposed to do

[idle kindle]

if there is a bucket of water in the dispenser and an empty boiler opposite, then replace the boiler with a boiler of water, remove the bucket of water and add a bucket

[tall dragon]

so bassically, the dispenser shoots its water into a cauldron?

[fickle frost]

Be a bit more descriptive than "item dont remove" when describing what's going wrong.

[idle kindle]

one minuts

https://youtu.be/uNrQbHLbYXc

https://pastebin.com/GU3FEMT0

[tall dragon]

huh. why would it add lava when there is water in the dispenser

im am confuse

[fickle frost]

That's kinda funny.

[tall dragon]

first of all

[fickle frost]

Anyway:

                    if (!inv.contains(item)) {```
This makes no sense. 
You're looping over the inventory nine times just to perform the exact same check every time.
Moreover, due to your check, you're only attempting to remove the bucket if the inventory doesn't contain a bucket.

[tall dragon]

im pretty sure all of your for loops are useless

[fickle frost]

Remove the loop and invert the bucket check and you'll probably get some better results.

[boreal frost]

I am working on a program that once it moves it never stops again. I added Velocity to X and Z and it stopped falling, so I tried adding Velocity to Y but it doesn't come close to minecraft's behavior. I would appreciate if you could help me.

Here's the code now.

        Location loc = p.getLocation();
        loc.setPitch(0);
        Vector vec = loc.getDirection();
        p.setVelocity(vec.multiply(0.4f));
        p.addPotionEffect(new PotionEffect(PotionEffectType.JUMP,10,10));
        if (!fallMap.containsKey(p)) {
            fallMap.put(p,Bukkit.getScheduler().runTaskTimer(this, new Runnable() {
                @Override
                public void run() {
                    if (p.isOnGround()){
                        time = 0;
                        fallMap.remove(p);
                        fallMap.get(p).cancel();
                    }
                    time += 0.25;
                    p.setVelocity(p.getVelocity().setY((Math.pow(0.98, time) - 1) * 3.92));
                }
            },0,1));
        }```

[rough drift]

So i am trying to reload my recipe, however i get "Duplicate recipe ignored with ID"

even if i call Bukkit.removeRecipe before

[rough drift]

so... just making something float?

[tender shard]

are you sure you removed the correct recipe?

[rough drift]

yes?

oh wait

lmao

[tender shard]

hm I doubt it

[rough drift]

i am

[tender shard]

I always loop over all recipes and remove ALL recipes that match my plugin's namespace in onEnable

[rough drift]

the brightest idiot there is

[tender shard]

print out the recipes you are removing and also the ones you are adding

[rough drift]

i have a recipeKey and a headKey, guess which one i was using

[tender shard]

the wrong one, as I said 😛

[idle kindle]

how

[fickle frost]

Remove the ! from the if statement which checks the inv for a bucket.

[tender shard]

you are removing a bucket from the inventory if the inventory does NOT contain a bucket - that's probably wrong, isn't it?

[idle kindle]

i removed ! and code dont work

[fickle frost]

Then there are more bugs you need to find.

[tall dragon]

you also need to completely remove your for loops

its useless to do the same check 9 times.

[idle kindle]

How do you check inventory then?

[fickle frost]

You're doing that here:
if (!inv.contains(item)) {

[tall dragon]

^

[fickle frost]

You'd only need to loop over the inventory if you were going to use the index to individually check the item in each slot of the inventory.
But you're not checking each slot yourself, you're using the InventoryHolder#contains method to do that check for you. It will return true if any of the slots in the inventory contain the provided item.

Downside of that is you don't know which slot contained the bucket and which slot you removed the bucket from, but that's probably unnecessary for your purposes.

[unreal turret]

Is there a way to prevent EntityDamageByEntityEvent from responding in entity.damage ()?

Or is there a way to reproduce the damage?

[tender shard]

what do you mean with "preventing" it "from responding"?

exit

[unreal turret]

I want to skip the processing of the Event caused by damage()

[tender shard]

I don't think you can do that

you can instead directly set the health

entity.setHealth(entity.getHealth() - yourDamage);

[novel basin]

How can i setup a blank plugin in vscode? I read the tutorial thing on the spigot website but i dont understand anything.

[rough drift]

quick question

why not use intelli

it has the mc dev plugin and it allows you to auto setup

[novel basin]

i just prefer vscode

[rough drift]

alright

anyways what do you not understand

[novel basin]

everything smh

[fickle frost]

Have you set up a project in vscode before?

[novel basin]

yeah i do python on vscode but i have never do java

oh i havnt install maven im smart

[rough drift]

can you check if an item has been renamed in an anvil? (so the input's name does not match the output's name)

What i am trying to do:

Whenever my custom skull is renamed, it will set its owner to the name of the skull, now this works, however after a couple times you do this it will go crazy and kick the player for too many packets, here's my current code:

@EventHandler
public void on(PrepareAnvilEvent event) {
    ItemStack result = event.getResult();
    if(result == null) return;
    if(result.getType() == Material.PLAYER_HEAD) {
        SkullMeta meta = (SkullMeta) result.getItemMeta();
        OfflinePlayer player = Bukkit.getOfflinePlayer(meta.getDisplayName());
        meta.setOwningPlayer(player);
        result.setItemMeta(meta);
    }
}
```(I still need to add the check for my skull, however its just easier to test without it)

by going crazy i mean the skull keeps changing its owner as soon as i add it to the anvil slot (note: this is for every skull in the inventory, they all keep changing between steve and alex and i have no clue why)

when a dispenser is in front of a cauldron, check if the dispensed item is a bucket or a lava bucket. if it is, check whether the cauldron already contains lava or not, and then cancel the event and manually add / remove lava and exchange the bucket with a lava bucket or empty bucket inside the dispenser

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

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

[tender shard]

"the program asked you to" because you used TRUE instead of true

print out some debug statements whether it actually cancels the event. I bet one of your if statements returns false

[idle kindle]

do you suggest replacing the former letters with small ones?

i want make player can't break specific block event that can be turn on/off by command
can someone check?
https://pastebin.pl/view/7fdbba19
the event still going on even i run /enabledisable disable

[crude loom]

Is there a way I can display a message lower in the screen than what ChatMessageType.ACTION_BAR does?

[fickle frost]

The Minecraft client has limited positions available for displaying text.
Without modifying the client, displaying text outside of those positions isn't feasible.

[crude loom]

I see, thanks for the help!

[sharp flare]

should be break

let me know if it works

🙂

[lean gull]

does anyone have a good understandable tutorial about protocollib packets for beginners?

?

i mean protcollib beginners, like someone who hasn't really used it before

i know like half of the java basics and i'm learning

https://wiki.vg/Protocol or wiki.vg in general

i'm currently watching this tutorial [https://www.youtube.com/watch?v=2FcnwD2MHOA&t=1491s&ab_channel=KodySimpson]
but it's a bit hard to understand cause he kind of explains words and expects me to understand it as if i know what it means

[sharp flare]

not all tutorials help or perfect

[crude loom]

Don't know if this is necessarily spigot related or java related but it there a way I can schedule a task and cancel it without having the object I used to schedule it in the first place?
(when I reload the plugin I lose the object so I won't to have a command that cancels previously created tasks)

[young knoll]

Reloading the plugin already cancels them

[tender shard]

sending packets with ProtocolLib is like 17 times more complicated then using NMS imho

[lean gull]

there are a lot of different opinions on nms vs protocol so idk which one to choose but i'll pick protocollib ig

[crude loom]

It doesn't do it automatically, from what I tested

[tender shard]

if the plugin gets disabled, tasks are cancelled

if you only reload it yourself, of course they won't get cancelled

just cancel all your tasks in your reload method

[crude loom]

I deleted the plugin and the tasks are still running, I know I can reset the server but I want to create an in-game solution to this

[haughty storm]

I want to spawn npcs using my plugin, but for some reason my intellij doesnt give me any imports from net.minecraft. These are the dependencies of my pom.xml:

<dependencies>
        <dependency>
            <groupId>org.spigotmc</groupId>
            <artifactId>spigot</artifactId>
            <version>1.18.1-R0.1-SNAPSHOT</version>
            <classifier>remapped-mojang</classifier>
            <scope>provided</scope>
        </dependency>
    </dependencies>

[tender shard]

what classes do you want to import?

obviously class names are different in remapped-mojang

[haughty storm]

MinecraftServer

[tender shard]

that's the correct name, yes

did you click the "maven reload" button?

[haughty storm]

yup

[tender shard]

what import are you using for MinecraftServer?

it should be "net.minecraft.server.MinecraftServer"

[haughty storm]

That import doesnt exist for me

[tender shard]

do File -> Invalidate Caches, check all boxes then click on "Invalidate & Restart"

[haughty storm]

ok, I'll try that

[tender shard]

it might take a few minutes after restarting until it works again

[haughty storm]

ok

Still not working

amnd on the right side it gives me an error but doesnt tell me why

[tender shard]

you did run buildtools for 1.18.1 using --remapped though, right?

[haughty storm]

I ran them using ```
java -jar BuildTools.jar --rev 1.18.1

[tender shard]

You must add --remapped behind it

[haughty storm]

ok, give me a sec

[tender shard]

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

[ivory sleet]

Yeah, the entity should get removed the next tick if everything goes as it should (I believe)

[haughty storm]

Works now tysm

[tender shard]

Np

[crude loom]

Anyone knows how to approach this?

[late sonnet]

its better restart than try a ingame solution using plugman for load a plugin for cancel a task for a deleted jar.

any problem with my code? i want set a chest at specific coordinate with item inside

but i got error` Cannot invoke "org.bukkit.World.getBlockAt(org.bukkit.Location)" because the return value of "org.bukkit.Location.getWorld()" is null`

[tender shard]

you don't have a world called "neweventbow"

[last tulip]

i do have

also why are you waiting a tick?

ya i just remove it, i was copy it from onBlockPlace event and i need a tick so there is no error

the part below materials

where do I find it?

[crude loom]

Is there an event that allows me to check if a player is holding an item or do I have to use a runabble for it?

[lost matrix]

What version?

[quaint mantle]

1.8.8

[rough drift]

iirc just a runnable

[rough drift]

ah yes, 1.8

[quaint mantle]

its good men 🔫

[lost matrix]

This version is half a decade old and support was dropped years ago. In newer versions there is a LOT of api that you are missing out.
So for you its SkullMeta -> GameProfile -> use reflections to get properties

[crude loom]

If I run a check on every online player every half a second would that be really heavy on the server?

[tacit drift]

or use nbtapi

[rough drift]

https://tryitands.ee

[lost matrix]

No its not and nobody uses it. Update to a supported version or live with the horrible drawbacks like having to use reflections to get textures from a skull.

[quaint mantle]

it is

trust me

[rough drift]

well i mean, 1.8 is good for joining hypixel

thats it

[hardy swan]

no, it shouldn't

[lost matrix]

I trust the statistics and they state 7%

[crude loom]

Oh ok , thanks!

[quaint mantle]

imagine using 1.18 to play bedwars

[hardy swan]

imagine developers playing minecraft

[lost matrix]

But if you want to squeeze out every last bit of performance then you should try evenly distributed runnables.

How to change the skin of a player?

[red sedge]

[lost matrix]

You can change the textures of his GameProfile. You just need to make sure that the other players receive this change somehow.

[sage patio]

Hi, I have a NPC made with packets, i want to move this npc realistic ( not teleport, walking ), if anyone can help me create a thread thanks.

[rough drift]

use A*

[sage patio]

wdym " use A" ?

((CraftPlayer) player).getHandle().playerConnection.sendPacket(new PacketPlayOutEntity.PacketPlayOutRelEntityMove(entity.getId(), (short) (x * 4096), (short) (y * 4096), (short) (z * 4096), true));

[rough drift]

A* is a pathfinding algorithm

[lost matrix]

Was about to post a link to the protocol. This should be used for letting a fake entity walk.

Although i see a lot of other packets that might be needed for predictive computing by the client like velocities and player position/look

[rough drift]

iirc mc does not have prediction

atleast not for players/entities

[lost matrix]

I almost certainly has. 20TPS would look scuffed otherwise.

Is it possible to change the fade out time of the player.spigot().sendMessage() method?

[red sedge]

that still wont work

[rough drift]

no it would

if you keep doing it

[red sedge]

...

[rough drift]

chat will keep displaying new msgs

[crude loom]

player.spigot().sendMessage(ChatMessageType.ACTION_BAR,new TextComponent(""))
like so

[rough drift]

well, you can try resending it after a bit

[crude loom]

But it will take time to fade out

[lost matrix]

Action bars dont have a fadeout timer. You need to send a new one if you want to replace or remove it.

[crude loom]

Ohhh I can send a clear one to remove it, that will work, thanks!

[tribal holly]

What do you advise to host a public repository ? (What type of service is good to use ?)

[lost matrix]

caugh citizens has abyssmal performance and i consider it a borderline virus

[lost matrix]

I always go with nexus

[tribal holly]

Nexus okay thanks i will check this

[lost matrix]

There is also Artifactory and something called frogged (or something similar)

[tribal holly]

There is so much things, this is why i ask. For which is the most use and the most documented

[lost matrix]

What does this question aim at? Why the performance is abyssmal or why i consider it a borderline virus?

[tribal holly]

https://github.com/zelytra/Histeria/tree/master/src/main/java/fr/zelytra/histeria/managers/npc check this code if you wanna do it your self with nms and packets

[haughty storm]

thx, I'll try that

[tribal holly]

try to understand it, before using it

[lost matrix]

1. I dont know why the performance is so bad. Ask the citizens devs.
2. I consider it a borderline virus because the performance is so bad. (20% tick time with 0 players online)

[tribal holly]

wtf 20% ??

[haughty storm]

of course

[lost matrix]

Its been a while since ive used it (about 3 years) and back then it just hogged all the cpu time it could get.

[tribal holly]

btw there is a lot of feature with path finding etc so maybe there is some justification

(ore just very bad code optimization)

@lost matrix sry for the ping just a question, is Nexus free ?

[lost matrix]

yes. You just need a host and some time to set it up.
Dabbling with nginx and ssh key for https connections is really a hustle.

[tribal holly]

okay, but i wanna make my repo public (so any password and user to set for the user) is it possible and secure ? Or did i need to make it absolutely private ?

[lost matrix]

It has quite a bit of security features and is also used by bigger companies. You can make public repos with it.
But you can also check out jitpack.io
Its a really simple way to host maven dependencies. You just provide a github repo and
its automatically compiled and hosted there.

https://jitpack.io/

[tribal holly]

hooo well quite nice solution too

okay thanks for all infos

[lean gull]

what is it called when someone does something like "void hi();" in an interface

is it a function or somethin? idk what it is

[lost matrix]

method. And in interfaces all methods are implicitly public and abstract.
So its a public abstract method with no return type and no parameters called "hi"

[lean gull]

i don't understand

could you dumb it down?

[lost matrix]

Nope. Google the words.

[lean gull]

gee thanks

[viral crag]

it is not really a serious programming question - kind of surprised you got an answer

[lean gull]

forgot for a second how annoying everyone is here

[viral crag]

[vocal cloud]

"annoying" vs not wanting to teach java concepts to people because you should already know them

[lost herald]

No offense, but if you want to write a whole plugin, learning basic programming concepts might be a good idea

[lean gull]

im fine with them not wanting to teach me, im annoyed by how they said it

and im annoyed on lowonespresso

[viral crag]

What would you like for me to make it up to you? - codeacadamy has pretty simplified explanations

You're annoyed that someone said no they're not going to dumb down important concepts you should know and you're annoyed someone directed you to a page to learn said concepts. I don't know what to tell you

[quaint mantle]

hey how to get a location object with a specific coordinate that I have

[eternal night]

if you have the world and the x,y and z

just use the location's constructor

[quaint mantle]

sample code please

[eternal night]

final double x = 10, y = 20, z = 30;
final World world = ...; // Whatever world

final Location location = new Location(world, x, y, z);

[neon nymph]

Are there any downsides to having a lot of methods in a class? Say an average method in a class has at least a runnable in it, and there are like maybe 3000 lines of code worth of these methods. How does that affect the program?

[hasty prawn]

The computer doesn't care, but it makes it look awful and hard to debug.

And your mouse's scroll wheel :(

[lost matrix]

It makes this code really unclean and hard to maintain. And i would assume that it makes it unmodular as well.

Pretty sure that there is no chance that you can write code like that without violating clean code principles at least several dozen times.

[brave sparrow]

I would argue having a ton of functionality inside 3-4 methods is harder to read

Than having the code broken up into small units

Not programmatically

[raw ibex]

just saying that in future @quaint mantle you should use javadocs for simple stuff like that

[lost matrix]

Only for slimes. Minecraft doesnt support that for anything else.

[quaint mantle]

hmm alright thankyou

have a good day guys
thanks for helping me
Byyeee

[raw ibex]

why is he ignoring me

[neon nymph]

Hmm, I see. So follow-up question, how would one efficiently and optimally write/store multiple unique instances of an object? Basically like enums, but for objects. I'm planning to write my own GUI lib and I figured I'd be creating a lot of items as buttons of these GUIs with their own trigger methods (runnables I mentioned earlier) and that was my earlier concept, multiple methods that return a specific itemstack. I figured if I were to create a new item, I can simply add another method

[dull whale]

how can I stop the sitting animation?

[lost matrix]

So the current best practice for that is creating a wrapper class that contains
A) An ItemStack to display or a Supplier<ItemStack> or a Function<Player, ItemStack>
B) A consumer for the InventoryClickEvent which i called when the ItemStack is clicked.
Lets call this class UIButton

Then a GUI contains a mapping slotID -> UIButton.
So a Map<Integer, UIButton>

[lost matrix]

Ill follow up with an example

[hybrid spoke]

stop? like stand them up or like they sit but stand?

[dull whale]

sit but stand one with packets

[lost matrix]

The button class:

@Builder
@AllArgsConstructor
public class GUIItem {

  @Getter
  private final Function<Player, ItemStack> iconCreator;
  @Getter
  private final Consumer<InventoryClickEvent> eventConsumer;

}

Then inside your GUI object there should be something similar to a

  private final Int2ObjectMap<GUIItem> buttonMap = new Int2ObjectOpenHashMap<>();

Then you can fill this map with buttons

    GUIItem item = GUIItem.builder()
            .iconCreator(player -> new ItemStack(Material.RED_WOOL))
            .eventConsumer(event -> event.getWhoClicked().sendMessage("You clicked red wool"))
            .build();
    buttonMap.put(10, item);

There is quite a bit more to that but those are the core concepts.

[neon nymph]

Okay, I'll look into this further. Thanks for introducing it to me!

[dull whale]

my goal is to make player unable to move

[crimson terrace]

keep teleporting them to the same position every tick or 2?

[tall dragon]

or just set their movespeed to 0?

[crimson terrace]

that would enable them to be moved by others with knockback I assume

[tall dragon]

true

[dull whale]

I thought i could just make them sit on something

that wouldnt seem laggy too

because if they dismount, thats no problem for me

[lost matrix]

Oh so you want to cancel them dismounting? Just cancel the EntityDismountEvent then.

[torn yarrow]

Hi.. I'm trying to update an old abondoned plugin and it has these import org.bukkit.craftbukkit.v1_13_R2.inventory.CraftItemStack; import net.minecraft.server.v1_13_R2.NBTBase; import net.minecraft.server.v1_13_R2.NBTCompressedStreamTools; import net.minecraft.server.v1_13_R2.NBTTagCompound; import net.minecraft.server.v1_13_R2.NBTTagList; ... trying to find the right imports for gradle.. for 1.18.. not even sure that stuff is in the same place in this version now though

[dull whale]

no I want to cancel the sit animation

[fading lake]

In 1.18 the v1_13_R2 stuff was removed, try it without it

[lost matrix]

If you want them to sit down without showing the animation then you would have to intercept the backets.

[lost matrix]

This looks like it should be re-written using pdcs

[fading lake]

so import net.minecraft.server.NBTTagCompound (might not be exactly like that I'm a 1.8 dev)

[dull whale]

I know I tried it using packets but couldnt

[fading lake]

@torn yarrow

you want to make a player sit down without sitting down?

[lost matrix]

And in 1.18 there are not spigot mappings anymore. So you need mojang mappings which have a completely different package
structure and naming. So what Macho suggested will 99% not work,

[fading lake]

rip

what did they change it to, all I know is its not version mapped anymore

[lost matrix]

The try again or use a different approach.

[torn yarrow]

what is the gradle import for net.minecraft.server. ... I can't find even that

[fading lake]

in every other version its buildtools spigot but it mightve changed

[lost matrix]

You need to install spigot into your local maven repo and depend on it just like you would do with maven.

[dull whale]

yes so they just wont be able to move Ive been looking for a wayto do it for soem time now

[lost matrix]

Actually ive only done 1.17/1.18 with gradle by using the userdev plugin from paper.
For spigot i always used special sources.

[lost matrix]

The most trivial approach is to just cancel the PlayerMoveEvent

[fading lake]

why do they have to be sitting down?

[viral crag]

repositories {
    mavenLocal()
    mavenCentral()
    // Spigot
    maven { url = 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/' }

   // maven { url = 'https://oss.sonatype.org/content/repositories/snapshots' }
    // maven { url = 'https://oss.sonatype.org/content/repositories/central' }
}

dependencies {

    compileOnly 'org.spigotmc:spigot-api:1.18.1-R0.1-SNAPSHOT'
    // Spigot Annotations Support - Replaces plugin.yml
    compileOnly 'org.spigotmc:plugin-annotations:1.2.3-SNAPSHOT'
    annotationProcessor 'org.spigotmc:plugin-annotations:1.2.3-SNAPSHOT'

}

[dull whale]

because if I cancel the playermoveevent or loop teleport it seems too laggy

[fading lake]

cancel the move event like smile said, make them fly about 0.01 blocks off the ground, make it so they cant disable it (PlayerToggleFlightEvent) and set their fly speed to 0

Either that or set their walkspeed to 0 and give them negative knockback to kill jumping

[dull whale]

so canceling the sit animation isnt posibble?

[lost matrix]

wong ' char and the file type is not java but groovy. Unless you are using kotlinDSL

[viral crag]

aha

[fading lake]

not effectively, how would a player just randomly decide they want to sit?

unless you're doing it through packets

[lost matrix]

Just for the surrounding players. You can just make them think that the player did not sit down in the first place.

[dull whale]

but not the player himself?

[fading lake]

no thats client side

because minecraft

[dull whale]

thanks then Ill just loop set walkspeed 0

[idle kindle]

can you write a plugin that will allow dispensers to pour liquids into boilers?

[fading lake]

I mean you shouldn't need to loop it, their walkspeed wont increase on its own

[torn yarrow]

that worked.. i can import import net.minecraft.nbt.NBTTagCompound; now

[fading lake]

wat

[lethal python]

boilers?

[fading lake]

[idle kindle]

I'm tired my code doesn't work in practice

In order to grant a specific permission to a player, should I do it in my own plugin , or find a plugin that will handle that?
Or it doesn't matter

[idle kindle]

https://pastebin.com/sLYiE9DM

[lost matrix]

Sure. Should be as simple as just listening to the BlockDispenseEvent

[fading lake]

you can just do that in a permissions plugin unless you have your own perms plugin

[lost matrix]

Usually you would go for Vault

[idle kindle]

https://youtu.be/3zjE_x-14wg

[crude loom]

How would I do that?

[crude loom]

If I want do to it on my own, that would require a vault?

[fading lake]

no but Vault makes other plugins communicate with eachother properly

so its recommended

It says it couldnt find the ServerPlayer class but I imported in my code

import net.minecraft.server.level.ServerPlayer;

And in my pom.xml arent any errors but on the right hand side it gives me an error at the dependencies

[tall dragon]

check if the class is inside your compiled jar

[haughty storm]

how?

[tall dragon]

open it with something like winrar

[rough drift]

is there an event when a player clicks on an item and it goes to cursor? so far InventoryClickEvent#getCursor only returns the item in the slot after it clicked

[tacit drift]

the jar class paths are not like that

for the server

[haughty storm]

ok, gimme a sec

[lost matrix]

Try this and show me the result:

    @EventHandler
    public void onDispense(BlockDispenseEvent event) {
        Block block = event.getBlock();
        if (!(block.getBlockData() instanceof Dispenser dispenser)) {
            return;
        }
        Block target = block.getRelative(dispenser.getFacing());
        if (target.getType() != Material.CAULDRON) {
            return;
        }
        ItemStack dispensedItem = event.getItem();
        if (dispensedItem.getType() == Material.LAVA_BUCKET) {
            event.setCancelled(true);
            Levelled levelled = (Levelled) target.getBlockData();
            levelled.setLevel(7);
            Inventory dispenserInv = ((BlockInventoryHolder) block.getState()).getInventory();
            dispenserInv.remove(Material.LAVA_BUCKET);
        }
    }

[haughty storm]

I didnt put the class in my project but imported with my pom.xml I think (if that makes sense if not correct me xD)

        <dependency>

[brave sparrow]

If you’re using remapped nms you have to apply the mapping to your plugin to make it reference the obfuscated code in the compiled jar

You’re trying to reference the deobfuscated class

That doesn’t exist in the server

[rough drift]

?

[misty current]

iirc there is a maven plugin that auto remaps to obfuscated code

but if I place a renamed player head and break it it still has the name. So it needs to remember the name while it is placed somehow

Don't just copy paste your errors here without any thought, pay attention to what it's telling you

You already have a Dispenser import

There are two Dispenser classes

And add it locally from another project

If you want to not need to add it locally then you need to publish to a repo

Hello, could someone help me understand how I can create a custom entity using the NMS with armorstands in 1.18.1? I have several problems: The name of the fields with the obfuscation are difficult to identify, and for example is it possible to change the size of an armorstand, if so what is the property to modify?

and if you know an api that could simplify all this?

[quiet ice]

Read the 1.17 update post or something like that

?nms

eh

You get it

[tender shard]

you should use remapped spigot to get unobfuscated names

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

and for the size: you can only set an armorstand to be a marker or sth like that to make the hitbox smaller, I think there's nothing else you can do to its size

[rotund glade]

Ok thank i try it

[vague swallow]

lmao

I can't use PlayerProfiles

because required methods of the PlayerProfile are depreciated and marked as error

but if I remove them the full PlayerProfile is marked as error

[viral crag]

update them to the new method?

[round gale]

So, how do you assign a non-primitive Short in java?
Short.valueOf("1");?

[vague swallow]

No like

This is a PlayerProfile:

PlayerProfile profile = new PlayerProfile() {

};

But between the brackets there are a lot of methods like This one:

@Override
public @NotNull PlayerTextures getTextures() {
     return null;
}

or

@Override
public void setTextures(@Nullable PlayerTextures textures) {

}

But 2 of them are depreciated. Without them the PlayerProfile is marked as error and with them the methods are marked as error

These methods are implemented

@Override
public @NotNull String setName(@Nullable String name) {
     return null;
}
``` and ```
@Override
public @Nullable UUID setId(@Nullable UUID uuid) {
     return null;
}

Are marked as depreciated

[viral crag]

update()

[vague swallow]

where do I have to put that?

[viral crag]

hmm, creates new profile does not change existing ...

[viral crag]

no i am wrong, those two you can no longer change without creating a new one:
"A player profile always provides a unique id, a non-empty name, or both. Its unique id and name are immutable, but other properties (such as its textures) can be altered."

[vague swallow]

So what do I need to do now?

[viral crag]

either use update to async create a new player profile or clone - UUID and name are now immutable to prevent conflicts?

[viral crag]

why is it calling those two specifically, and are they actually doing anything with them? - if it is just a check, you could replace with isComplete()

[elfin steppe]

[river oracle]

I will make for 200 dollars ahaha

[ivory sleet]

if you cache the string, then its doable

MessageFormat is similar to String.format

[trail pilot]

oh, so default its the best option?

[ivory sleet]

depends on situation

[trail pilot]

i need to return player location

world x y z yaw pitch

[ivory sleet]

what does that have to do with string concatenation and string formation

[trail pilot]

and utils classes need to have all static methods?

[ivory sleet]

yes

the idea is that every utility is pure and stateless

[trail pilot]

oh ok

and should be initialized?

[ivory sleet]

well

no

[trail pilot]

like Utils utils = new Utils;

ah ok

[ivory sleet]

basically for any utility function, given the same input, the same output

thats useless

as its stateless and pure

so having an instance of it would just be useless

[trail pilot]

alright

[ivory sleet]

int square(int i) {
return i * i;
}

this is a utility function

regardless of circumstance

if I send in 2, I always get 4

[trail pilot]

oh

[next stratus]

hey, I had to shade some more things into my plugin and because of the file size it won't let me? What should I do?

[ivory sleet]

tho these would be stateful functions thus cant be utility functions:
Object getOwner() {
return this.owner;
}

void setOwner(Object newOwner) {
this.owner = newOwner;
}

[glossy venture]

use a downloader

[next stratus]

?

[trail pilot]

oh i get it

[ivory sleet]

for instance whenever calling getOwner you really don't know what you'll get

it depends on some state, right

and then we have methods like

Collections.shuffle()

and they are not utility functions either

just static helper functions

[trail pilot]

yea

[ivory sleet]

as they manipulate state

[trail pilot]

whats that mean?

[glossy venture]

i dont know how it would work exactly but maybe create a file libs.txt with urls, parse it and download all jar files from the urls and then load them dynamically

there should be a library for that

[next stratus]

but I use gradle

people are saying that obfuscating it makes it smaller but I don't wanna do that

[ivory sleet]

xnotro, that was a question concerning this

you just leaped from strings to sth completely else

[glossy venture]

ill try to make an example

[trail pilot]

my bad google translate is sht

[next stratus]

I can't even set a 3rd party link

[ivory sleet]

leap = jump

[glossy venture]

i mean to download and load the libraries at runtime

[ivory sleet]

concatenation means basically joining/merging

[next stratus]

i meant on spigot you can't even specify a link

[glossy venture]

?

[ivory sleet]

so "a" + "b" is string concatenation as you're joining/merging strings

[next stratus]

like you can't say download the jar from test.com/file.jar

[trail pilot]

aaa got it

[elfin steppe]

when i set their hp back to 10 on entitydamageevent, the zombie is still able to put me to 9hp n only then it doesnt go lower

like it gets me to 8.5 then it stays there then i regen to 9 then it goes back to 8.5 etc

while he keeps hitting me

[crimson terrace]

just put it back to the Attribute.GenericMaxHealth.getBaseValue() maybe?

[elfin steppe]

if (e.getEntity() instanceof Player) {
Player p = (Player) e.getEntity();
p.getAttribute(Attribute.GENERIC_MAX_HEALTH).getBaseValue();
}

so j like that?

well dont really need the variable but anyways

[raw ibex]

the easiest way i've thought of making a bedwars plugin is using a togglable event handler, but i don't know if that is the way to go (i have started this). any suggestions??

[trail pilot]

an other question

what's is the best option:
HomeUtils.saveHomesFile();
or
import static dir.HomeUtils.saveHomesFile;

I never understood what changes

[elfin steppe]

@crimson terrace wait how do i set it after getting the value

[undone axle]

https://hub.spigotmc.org/stash/

[ivory sleet]

dont import static

usually it causes a lot of confusion as you don't see the caller

[trail pilot]

alright thanks, love you dude

[ivory sleet]

(its fine in some very special cases but generally avoid it)

nw :]

[elfin steppe]

Conclure can you help me out?

[ivory sleet]

Sure, what's the issue?

[elfin steppe]

I need a player to take knockback on a hit but to not lose any health

[raw ibex]

can't you just set damage to 0

[elfin steppe]

But i can't just do sethealth 20 on entitydamage event

[lost matrix]

Just set the damage to 0

[elfin steppe]

7smile7 then they wont take knockback either

or

am i dumb

[raw ibex]

yea

no

just set the damage to 0

[elfin steppe]

Alrighty

[trail pilot]

an other good question how i can save data when player quit in this case his home

so the server dont need to debug always

[raw ibex]

^ @ivory sleet ping for help :)))

[lost matrix]

PlayerQuitEvent -> save his data

[ivory sleet]

xnotro yeah tho I'd suggest to eagerly save data if possible

[trail pilot]

because this plugin create home when you do the command and instaly save it

[ivory sleet]

hmm, I mean could just have a boolean which decides whether your logic is going to be executed

[grim ice]

any lib idea

[next stratus]

hey, how can I only compile certain modules fro mthe XSeries?

[trail pilot]

because of the method

saveHomesFile();

[lost matrix]

I would honestly try to always register listeners once and then use control structures to define where the events are needed.

[trail pilot]

public static void saveHomesFile() {
        try {
            yaml.save( file );
        } catch (IOException e) {
            e.printStackTrace();
        }
    }```

really simple

[ivory sleet]

OrlaDev of course you could unregister and re-register the given listener

but that comes with some drawbacks

[raw ibex]

is that the best way though

i was just wondering

[ivory sleet]

mainly that you probably want to rebake the handlers after re-registering to achieve better performance

[elfin steppe]

Sorry, but which event do i need to use for that

Just EntityDamageEvent?

[raw ibex]

EntityDamage Event

[ivory sleet]

which if there are many listeners and event executors registered will probably halt the server

[elfin steppe]

@EventHandler
public void onDamage(EntityDamageEvent e) {
if (e.getEntity() instanceof Player) {
Player p = (Player) e.ge();
p.getAttribute(Attribute.GENERIC_ATTACK_DAMAGE).setBaseValue(0);
}
}
Can u tell me what i'm forgetting

[ivory sleet]

so go with what smile said

[raw ibex]

you need to setdamage

[ivory sleet]

e.ge()

[signal meteor]

how can i make a function in java ?
i dont understand the articles in the internet :/ i want to teleport a player to a location, but thats too many code to use everytime. so i want to create a function like "player.resetlocation()" :D

[elfin steppe]

oh oops

[raw ibex]

e.setDamage() iirc

[elfin steppe]

oh okay

[raw ibex]

@elfin steppe

[elfin steppe]

so no need to do attribute

[lost matrix]

I find it hard to keep track when listeners are registered or not. Its dangerous because you might end up with multiple registered listeners.

[raw ibex]

cos all my listeners will be for the game anyways

[lost matrix]

[undone axle]

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

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

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

[lost matrix]

Spigot is not beginner friendly

[raw ibex]

so they're all gonna be off or on either way

[haughty storm]

how would I make a ServerPlayer behave like a dog, so it would follow you around and attack enemies

[lost matrix]

Maybe if you pay him enough. There are weird people out there.

[ivory sleet]

OrlaDev do it like

boolean shouldRunSomeEvent;

@EventHandler void onSomeEvent(SomeEvent event) {
  if (shouldRunSomeEvent) {
    //TODO: ACTUAL LOGIC
  }
}

void shouldRunSomeEvent(boolean toggle) {
  shouldRunSomeEvent = toggle;
}```

tho ofc that design isnt particularly scalable

but you get the gist of it

[haughty storm]

what kind of currency do you think he would accept

[lost matrix]

DogeCoin

[elfin steppe]

works, thank u

[haughty storm]

I'll try that

[ivory sleet]

sounds like you need to deal with packets here

or at least nms

[lost matrix]

ServerPlayer doesnt have any AI logic implemented. So this will be quite hard.

Means you cant just throw all the AIGoals of Wolfes at it.

[haughty storm]

could I maybe just give it motion in the right direction to follow and make it seem like its attacking stuff or is it not possible to give them motion

[trail pilot]

IJ IDEA its suggest to add @NotNull to my Utils Methods

[lost matrix]

What you could do is use LibsDisguises if you want the easy way out.

[trail pilot]

whats i need to do? ignore it?

[lost matrix]

Just disguise a Wolf as a player.

[haughty storm]

how would that work

[quiet ice]

You can but nullabillity annotations can be nice

[trail pilot]

i just google it and yea its cool to add it lol

[raw ibex]

ty :)

[quaint mantle]

How can I change the radius and damage of a fireball's explosion thrown by a custom item?

[raw ibex]

yea but i wanna turn them on and off with a command

[raw ibex]

custom item?

well we don't know anything about your custom item

what item is it?

[glad radish]

Should be able to modify the explosion power of it directly

Fireball is what they said

Not charge

[quaint mantle]

Wooden hoe with custom data that fires a fireball.

[raw ibex]

ok

how are you firing the fireball

[tall dragon]

for example

Fireball fireball = (Fireball) world.spawnEntity(new Location(world, 0 ,0 ,0), EntityType.FIREBALL);
        fireball.setYield(yourValue);

[haughty storm]

How would I implement that

[quaint mantle]

Hold on, lemme see if it does the trick. Thanks for the input, by the way.

[lean gull]

anyone have a good tutorial on creating a 1.18.2 plugin with maven? i usally use the Minecraft Development plugin in IntelliJ but it doesn't have 1.18.2

[viral crag]

just set the version to that

[glad radish]

Looks like the method call you need is setYield() and should be able to run that off any explosive thing

[lean gull]

huh?

[eager sapphire]

Does anyone know if there is an event for when a shulker box, as a dropped item, is destroyed and then it vomits out its contents?

[raw ibex]

wait is fireball an actual entity?

[viral crag]

   <dependencies>
        <dependency>
            <groupId>org.spigotmc</groupId>

            <scope>provided</scope>
        </dependency>
    </dependencies>

[raw ibex]

i didnt know that

[quaint mantle]

Do you happen to know how to change the damage dealt by the explosion?

[tall dragon]

yea, ofcourse

[tall dragon]

well setYield is how big the explosion is. i don't think you can modify that directly

you would need to listen to EntityExplodeEvent and set the damage yourself probably

[quiet ice]

Why would a fireball not be an entity? In mc space everything is either a block, and entity or a particle

[quaint mantle]

Thank you very much, this helped a lot

[quiet ice]

And it sure isn't a particle (those are usually smaller) and isn't a block at all

[raw ibex]

lol i didnt know

[tall dragon]

well, its like geol explained

[raw ibex]

lmao i just realised that ghasts throw fireballs 🤦‍♂️

i thought that they didn't exist in vanilla

im dumb :)

[quiet ice]

Pretty sure the dragon throws them too

[tall dragon]

dragon throws other things

[raw ibex]

yea

[tall dragon]

not sure the name is rn

[quiet ice]

Yeah idk

[raw ibex]

they throw particles

[tall dragon]

no

pretty sure he throws something similar

yea

DragonFireball

aperantly

[raw ibex]

ok

[quiet ice]

Well, close enough ;)

[raw ibex]

didn't realise that

[tall dragon]

public interface DragonFireball extends Fireball {}

which is. well... haha

[raw ibex]

being the idiot i am

[raw ibex]

lmaoo

[lean gull]

how do i open buildtools to look at all the craftbukkit, bukkit, spigot stuff? i forgor

[raw ibex]

it's basically a fireball

[tall dragon]

yup

[raw ibex]

maybe google?

[quiet ice]

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[tall dragon]

i think its purple instead of flamy

[quiet ice]

Yeah

Stash is fine as long as you don't want to see nms

[eager sapphire]

Sorry for the immediate-reask, I got kinda drowned but also guessing this is just not a thing:

Does anyone know if there is an event for when a shulker box, as a dropped item, is destroyed and then it vomits out its contents?

[tall dragon]

when does this even happen?

[eager sapphire]

if you throw a shulker box in lava is the easiest way

[next stratus]

how can I generate something like this? https://i.imgur.com/9kQeucX.png it was used on featherboard but idk how he did it

[eager sapphire]

but also if it explodes while dropped

[tall dragon]

but... then the items will be destroyed too?

[eager sapphire]

like from a creeper or fireball or whatever

no

well yes, in lava

unless they are netherite

but in the creeper/fireball/explosion case, the items inside the box survive regardless

it's a very specific/weird behavior I only just learned about but is causing me some dupe exploit headaches.

It seems like there's no real way to catch it

[viral crag]

in what version?

[eager sapphire]

1.18, but I think it's been like this since 1.17 or maybe 1.16

[tall dragon]

@eager sapphire you could test if EntityDeathEvent is fired

[eager sapphire]

I want to say Mojang changed it specifically to avoid netherite tools burning when inside a shulker box thrown in lava 😐

[eager sapphire]

I could, but then I have to .. wait a tick and scan the surrounding area for dropped items? Very messy at the least

[tall dragon]

im not sure. but i think it should be called when a shulker box item gets destroyed

you can get the item being destroyed

& get its contents?

[eager sapphire]

true, then again scan for the dropped items, check if it was something in the shulker box, etc

still very messy, an event would be nice but I'm guessing it doesn't exist

[quiet ice]

It's interesting as I have never heard about this feature, but is plausible and it makes fully sense that this would yield exploits

[tall dragon]

well, no dedicated event no.

[eager sapphire]

I had never heard about this feature either, until someone came complaining to me about exploits 😂

[tall dragon]

yea i never heard of this either

[quiet ice]

It should def. get an event however

[eager sapphire]

it is very much true though

I spose I could PR one 😄

[vocal cloud]

Well entitydeathevent has a list of drops you wouldn't need to scan anything they would be in there

[eager sapphire]

hmmm well that is a good point, if it really shows as drops like that, I will check.

[viral crag]

public static final GameEvent BLOCK_DESTROY should fire as a shulker is listed as a block

[velvet minnow]

Hi ! 😄
There is a way to set nbt to an item without use NMS ?

[quiet ice]

Bukkit unsafe

[eager sapphire]

Persistent metadata

If you want to use NBT to store your own custom data

[viral crag]

true

[eager sapphire]

not to hack up vanilla tags, there will probably never be an API for that 🙂

[quiet ice]

But beware, the bukkit unsafe is ... unsafe - better use NBT APIs

[tall dragon]

or just use this https://www.spigotmc.org/resources/nbt-api.7939/

very good api in my experience

[eager sapphire]

Possible X/Y problem why do you want NBT access? 😄

[vocal cloud]

You use the PDC if you're using a modern spigot version

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/UnsafeValues.html#modifyItemStack(org.bukkit.inventory.ItemStack,java.lang.String)

[velvet minnow]

Oh, I want to change vanilla tags ^^

[quiet ice]

Just note that there is literally 0 documentation on this method so you are on your own when using it

[eager sapphire]

What tags? ItemMeta should cover just about evrything

Really better to use the API unless you have an extremely exceptional case

[velvet minnow]

CustomModelData
Or may be i'm wrong and it's not a nbt ? 😛

[vocal cloud]

Ah good old xy problem strikes again

[eager sapphire]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/ItemMeta.html#setCustomModelData(java.lang.Integer)

😄

[tardy delta]

its the same line which is moved to the left for two blocks so maybe you could do something with that?

[velvet minnow]

Ah, i'm confusing meta and nbt then ^^

Thanks for your responses 😛

[tardy delta]

[next stratus]

Yeah, i'll try that ty

[eager sapphire]

To be clear, ItemMeta is really the NBT API.

All data on items is NBT. The ItemMeta API wraps this data, giving you safe access to it.

[eager sapphire]

In case you were curious, I just tested and it seems like EntityDeathEvent does not fire for dropped items

[tall dragon]

ah really

[viral crag]

then try GameEvent BLOCK_DESTROY will be noisy though

[tall dragon]
