[tidal skiff]

still does it

[young knoll]

When patching I just run CB

[tender shard]

but can't you just use the main jar anyway?

[tender shard]

then I have no idea. does it work when using other particles?

[tidal skiff]

havent tried yet let me see

[azure phoenix]

?

[young knoll]

I think you can compile it back to spigot using buildtools with --dont-update

(After committing your changes)

[tender shard]

normally you DO NOT want to run buildtools but just compile spigot using maven

[tidal skiff]

it seems to work fine with the heart particle but it has an animation so i wonder if its just a set animation for the particle

theres some extra data for the function im gonna try set to 0

[tender shard]

probably that fire particle just has random movements builtin

[young knoll]

Yes, the extra int controls speed on the fire particle

Or float, whatever it is

[tidal skiff]

ok i fixed it by setting the extra int to 0

alr ty

[tender shard]

:3

[azure phoenix]

worked, thanks :)

do u know why just mvn clean install doesn't work anymore?

[tender shard]

it should work. any error msgs?

[young knoll]

¯_(ツ)_/¯

[azure phoenix]

no errors

[tender shard]

and where's the problem?

[young knoll]

Probably because of the bootstrap stuff

[azure phoenix]

this happens when I run

[young knoll]

Which file

There should be several

[azure phoenix]

the one without bootstrap or remapping

[young knoll]

You need to run the bootstrap one

[azure phoenix]

I see

thanks :P

[tender shard]

mvn creates this file:

spigot-1.18.1-R0.1-SNAPSHOT-bootstrap.jar

it should run fine

inside SPigot/Spigot-Server/

[azure phoenix]

👍

[dark arrow]

       ShapedRecipe sr = new ShapedRecipe(NamespacedKey.minecraft("ProSword"),new ItemStack(Material.DIAMOND_SWORD));
       sr.shape("DDD"
               ,"DSD"
               ,"DDD");
       sr.setIngredient('D',Material.DIAMOND);
       sr.setIngredient('S',Material.DIAMOND_SWORD);
   }

i have tried that code now but it does not work and does not show any error also

[young knoll]

Well yeah, you need to add the recipe separately at startup

And then validate the ingredients using the event

[dark arrow]

ohh

[analog prairie]

i have some coding problem

Why I can not use chinese in kick message?

[tender shard]

wait whut?

you should not create a new crafting recipe in every PrepareItemCraftEvent

as Coll said: create the recipe ONCE on startup

buuuut

I already said:

this won't work

and also wtf

you use a minecraft namespaced namespacedkey

you should use your plugin instead

[tender shard]

you should be able to

[young knoll]

You would create a recipe with just the bare items at startup

[tender shard]

any error message?

[young knoll]

And then validate they have the data you want in the event

The bare recipe is just so the prepare craft event actually triggers

[tender shard]

well

the prepare event always gets called

even if no recipe matches

[young knoll]

Really?

Huh

[tender shard]

if always gets called when the matrix is changed, yes

let me double check, but im 99% sure

[analog prairie]

error: unmappable character (0xE9) for encoding x-windows-950

[tender shard]

my intellij doesn't want to open lol. but yeah I'm 99.9% sure because I'm using it in one of my plugins

[analog prairie]

event.getPlayer().kickPlayer(("雲端\nReason for ban >> "+jsonObject.get("response").getAsJsonObject().get("reason").getAsString()));

[tender shard]

that's strange. then it seems like the client simply doesn't like you for using chinese symbols

[young knoll]

I don’t think that’s the client

[dark arrow]

lol i am newbie everything is goind above the head but i am still try to undertstand and catch everythign

[young knoll]

Looks like you need to change the encoding in your IDE

[tender shard]

is that message appearing on compiling, or only when you run the code?

[analog prairie]

It still does not display properly in Minecraft

[young knoll]

You can also use Unicode escapes in strings

Like so \u0048

[tender shard]

that's a zero!

[young knoll]

The client should have textures for all the Chinese characters

I would think anyway

[analog prairie]

I try it now

[young knoll]

?

[analog prairie]

event.getPlayer().kickPlayer(("\u96f2\u7aef\u9632\u8b77\u7cfb\u7d71\nReason for ban >> "+jsonObject.get("response").getAsJsonObject().get("reason").getAsString()));

Is this right?

[tender shard]

try it

[mellow gulch]

does yml support utf8? might be worth trying to put the messages in a yml file so you don't need to escape every single character

and this solution (assuming yml does support utf8) would let you keep your sources ansi also

[young knoll]

It does if you save it as such

[mellow gulch]

(and would also make your plugin easily convertible to whatever language instead of hard coding the messages as chinese)

[dark arrow]

i think i found how to make custom r ecipes

how will i give the item a colored name

using setDisplayName

[young knoll]

ChatColor

[dark arrow]

is ti work for setDisplayName also?

i found this site

https://www.digminecraft.com/lists/color_list_pc.php

[mellow gulch]

it should, and afaik you can just use the reset color to remove the italics on custom named items

[dark arrow]

ok

[mellow gulch]

https://www.spigotmc.org/attachments/example2-png.188806/

your link was missing a few

lol nvm, i just didn't scroll down enough like an idiot

[dark arrow]

can i use font tag and color tag together?

[buoyant viper]

format and color? yeah

[mellow gulch]

what does fint mean? the format ones? yeah

beuh i am so dumb

lets go

its working

thx to everyone who helped me making is

tysm

😄

[tidal skiff]

hey all, i have kind of a weird problem:

im making a trap plugin and im trying to make a trap that encapsulates the victim in a 3x3 invisible wall that only theyre affected by and blah blah blah i have all that stuff down but i have a class for timed events and a class for the trap itself. before when i made an explosion trap it was pretty simple, the victim steps on the trap and it passes a location and a timer to the timed event class and after the timer drops to 0 then an explosion is created at the location, but this one is kind of weird. I need to pass 3 objects, a location, an int for the timer, and a player, but i havent found a way to do it. i used a hash map for the explosion trap but you obv cant fit 3 values into a hash map

im gonna try put a hash map inside a hash map wish me luck kekw

[ivory sleet]

I mean encapsulate the data with a class

If you’re on newer versions, you can even use a record

[tidal skiff]

lmfao i put a hash map in a hash map boys

[dark arrow]

bro i have completed the code to get shaprneed 5 dia sword after doing a specific recipe

now how will i make it so that it gives sharpness 6 or more then it

[ivory sleet]

That’s a terrible design

as said you should encapsulate said data in a new class and pass that type to the V type parameter

[dark arrow]

if i do using addenchants it just removes the enchants

[tidal skiff]

true

[dark arrow]

any solutions for that?

[ivory sleet]

Use addUnsafeEnchantments iirc

[tidal skiff]

pretty sure you need to use addEnchantment

[ivory sleet]

Something with unsafe

[tidal skiff]

in the item meta

im prob wrong

[dark arrow]

i did but i want to add sharpness 6

[ivory sleet]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/ItemStack.html#addUnsafeEnchantment(org.bukkit.enchantments.Enchantment,int)

[dark arrow]

when i add that

is just removes all the enchants

if i add shapness 5 then it add but if its sharpness 6 nothing happens

[dark arrow]

unsafe enchants?

[ivory sleet]

Check the link I sent

[dark arrow]

ok

how will i use it?

i cant type addunsafeenchants

[analog prairie]

I can add unicode to kick message

[ivory sleet]

Yes you can but not on ItemMeta if you’re observant

[analog prairie]

String msg= MessageFormat.format("\u96f2\u7aef\u9632\u8b77\u7cfb\u7d71\nReason for ban >> {0}",jsonObject.get("response").getAsJsonObject().get("reason"));

[ivory sleet]

Yeah although you need to make sure your compiler compiles with UTF-8 encoding or smtng

[analog prairie]

[16:21:05] [defaultEventLoopGroup-5-1/INFO]: [Geyser-Spigot] whes1015 從 Java 伺服器中斷連線，原因為 雲端防護系統
Reason for ban >> "\\u5916\\u639b"

[ivory sleet]

That’s due to gson

Which escapes the \

[analog prairie]

the problem is my unicode is \u5916\u639b

[ivory sleet]

Or whatever Json lib u use

[analog prairie]

It always display \ \u5916\ \u639b

[ivory sleet]

As said

It escapes the \

[analog prairie]

System.out.println(jsonObject.get("response").getAsJsonObject().get("reason"));

[16:21:04] [Server thread/INFO]: "\\u5916\\u639b"

[ivory sleet]

Try to append .replace("\\\\","\\")

[analog prairie]

So is Gson's problem?

[dark arrow]

can i add using itemstack?

[ivory sleet]

Might be

[ivory sleet]

Yes

[dark arrow]

ok

not working

[ivory sleet]

Send the code and never say not working, specify what does not work and what the wanted result is rather

[dark arrow]

sorry for not specifying

[ivory sleet]

No worries but just for any future references:)

[dark arrow]

        ItemStack item = new ItemStack(Material.DIAMOND_SWORD,1);
        ItemMeta meta = item.getItemMeta();
        meta.setDisplayName("§4Pro Sword");
        item.addUnsafeEnchantment(Enchantment.DAMAGE_ALL,6);
        item.setItemMeta(meta);

        proSword = item;

        ShapedRecipe sr = new ShapedRecipe(NamespacedKey.minecraft("pro_sword"),item);
        sr.shape("DDD"
                ,"DSD"
                ,"DDD");

        sr.setIngredient('D',Material.DIAMOND);
        sr.setIngredient('S',Material.DIAMOND_SWORD);
        Bukkit.getServer().addRecipe(sr);
}
    ```

[analog prairie]

It display correct but didn't change to chinese

[dark arrow]

ok 🙂

[ivory sleet]

Wym by that :0

[ivory sleet]

Oh yes, move the addUnsafeEnchantment under item.setItemMeta(meta);

It’s probably a bit weird to understand why that matters right now but ItemMeta is actually not a part of the ItemStack

[analog prairie]

[16:32:33] [Server thread/INFO]: whes1015 lost connection: 雲端防護系統
Reason for ban >> \u5916\u639b

[dark arrow]

ok

yay it worked

🙂

thx

[ivory sleet]

👍

[ivory sleet]

Actually it’s a bit more complicated now when I think of it

But how does your json look

Chances are you can read your json with utf8 encoding and get it to work that way

@analog prairie

So if you could share the code where you read the json file would be amazing

[dark arrow]

also how to make it so that they could only give shapneed 5 di amond sword for recipe and not any other diamond sword?

[ivory sleet]

ItemStack ingredient = …;
sr.setIngredient('T',new RecipeChoice.ExactChoice(ingredient));

[analog prairie]

I had dm you

[ivory sleet]

iirc

Ah right I’ll have myself a look

[analog prairie]

Thanks

[analog prairie]

I use UTF-8

[tidal skiff]

so do constructors not work in spigot or am i just fucking stupid

[ivory sleet]

They work

[tidal skiff]

public class TData {

    public static Location location;
    public static int timer;

    public TData(){}
    public TData(Location location_, int timer_){
        location = location_;
        timer = timer_;
    }
}

this is probably the simplest constructor ever but when i make a new TData object and try and use it like

[ivory sleet]

Remove static

[tidal skiff]

i need static

[ivory sleet]

No you don’t lol

[tidal skiff]

oh wait nvm

either way it doesnt work without them anyway

[ivory sleet]

Static globalifies the variables

It does

[tidal skiff]

wait nvm tf

ive tried without static???

this is rigged

anyway ty

[tidal skiff]

oh aight

[lavish hemlock]

don't do this (Location location_, int timer_)

_ is no longer valid in identifier names

[tidal skiff]

alr

why not tho

why arent they valid i mean

[lavish hemlock]

I'm not sure, I think it's because they're used as keywords in later versions

[sacred mountain]

does org.bukkit.particle; not exist i cant import it

[lavish hemlock]

keywords are stuff like public and static btw

ye Java is jank sometimes

[lavish hemlock]

Anyway

You should remove static.

[tidal skiff]

yeah i did

[ivory sleet]

Yeah they removed the possibility of using $ in variable names iirc

[lavish hemlock]

oh really?

dang

[ivory sleet]

Ye sadge

[lavish hemlock]

:(

[sacred mountain]

anyone know

[lavish hemlock]

So this pattern is what is called a DTO (data transfer object)

In Java, there's a very common way to define properties, which are getters and setters

Essentially, instead of allowing people to directly access your fields, you use methods to retrieve and set the value of the field

This is mainly to prevent binary incompatibilities as I understand it?

example:

private final String name;

...

public String getName() {
    return name;
}

If we were to refactor the above code to be conventional.

public class TData {
    private /* final */ Location location;
    private /* final */ int timer;

    public TData() {
        // this.location = <default here>;
        // this.timer = <default here>;
    }

    public TData(Location location, int timer) {
        this.location = location;
        this.timer = timer;
    }

    // Your getters here.

    // If you didn't uncomment the above code, then your setters would also be here.
}

Note: This is conventional, but not pretty. Java is not meant to be pretty.

[quaint mantle]

anybody cane help my with towny plugin'

[lavish hemlock]

If you want a pretty language, go look at Kotlin 😉

[lavish hemlock]

?ask

[undone axle]

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. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[dark arrow]

i tried it but nothing happened?

[ivory sleet]

That was just a sample code

You need to understand it and apply what I did just a little bit different

[dark arrow]

is it possible to make my new item with all those enchants and put it in ingredent?

[ivory sleet]

Think so

[dark arrow]

ok

ok

it worked

thx onceagain

[sacred mountain]

?

[dark arrow]

i was typing the wrong spelling xD

[ivory sleet]

You can’t import a package

[sacred mountain]

huh

[ivory sleet]

you could use org.bukkit.particle.*; tho that’s a bit slower

Ideally just import the class

[sacred mountain]

ok

[ivory sleet]

Well then that’s not a valid package

you know classes are case sensitive in terms of name

Actually a lot of stuff is in programming generically speaking

[onyx fjord]

Which spigot API version are you using @sacred mountain

[sacred mountain]

tried that didnt work

[sacred mountain]

im just using my 1.8.8 server jar

[onyx fjord]

Smh

[sacred mountain]

for referenced libraries

[ivory sleet]

[sacred mountain]

o

ok

[onyx fjord]

I guess that might be the reason

[sacred mountain]

i'm literally just tryna fix some stuff from another plugin, im not a great dev at all

idk whats wrong with ti

[onyx fjord]

@ivory sleet did 1.8 even have particle API?

[sacred mountain]

that will be a rip if it didnt

[onyx fjord]

Good reason to update

[sacred mountain]

well i cant really do that rn

is there any way to get a particle api in 1.8

like an external

[ivory sleet]

I don’t think so 🌚

[onyx fjord]

Because ?

[sacred mountain]

whole server is almost done on 1.8

its just this one class that im trying to fix without removing it

should i bother downloading particle api plugins and using those

[ivory sleet]

Yeah better than committing yourself to nms

[onyx fjord]

2bad

[dark arrow]

the maximum limit of enchants using commands is 32767 so unsafe enchants have the limit ?

[ivory sleet]

In newer versions 255

[dark arrow]

ohk

[trim crystal]

Hey, how do I use NMS to show a block as "cracked"?

[ivory sleet]

Step 0: you use the api

[trim crystal]

done

btw I'm on 1.18

I didn't know that it's a thing

I thought it's a protocollib thing

[ivory sleet]

🥲

Hi Conclure just to know, have you already any tips?

[ivory sleet]

Oh yeah link that thing

[cold field]

Don't worry 😂 https://github.com/Mr-EmPee/CommandManager

[summer scroll]

Can you remove the minecraft:paper and NBT lore?

[tacit drift]

no

[tidal skiff]

what was that text file thing that you could save data to like strings and ints and shit

i forgot what it was called

but i need to use it lol

[spiral light]

It's a client setting ... I think F3 and B

[analog prairie]

Can I display color on console?

[tacit drift]

you could change the itemstack thru packets probably

[royal vale]

Gets the brand of the currently connected server. May be null if the server hasn't yet sent brand information. Server brand information is sent over the {@code MC|Brand} plugin channel, and is used to identify modded servers in crash reports.

How do I change the server brand (which packet/plugin channel)?

[tacit drift]

https://github.com/zubiden/F3Name

[royal vale]

Will that change the server brand?

Or just the f3 brand

[tacit drift]

The F3 brand is the server brand i think

[wet breach]

I think the F3 Brand is the client

which, unless you have a mod that changes it or have a custom client, it is by default Vanilla

don't have the client loaded but I am sure someone can check really quick

if it says anything other then Vanilla on a spigot server, then we know its not from the client 🙂

[nocturne sinew]

difference between clients and launchers

[tidal skiff]

anyone know why getConfig().set("Traps.ExplosiveTraps", null); isnt working? im trying to reset the entire path

nvm i figured it out

anyway

anyone know how to iterate through a config like this:

Traps:
  ExplosiveTraps:
    '1':
      Location:
        ==: Vector
        x: 26.0
        y: 66.0
        z: 100.0
      PlacedBy: f780f203-cf11-4416-9e07-9ec21b37e476
    '2':
      Location:
        ==: Vector
        x: 30.0
        y: 67.0
        z: 109.0
      PlacedBy: f780f203-cf11-4416-9e07-9ec21b37e476

and get the vector values and uuids?

back into a hashmap i mean

or at least get the length of all the '1' '2' so i can iterate through the config directly

[spiral light]

You can save the length of this in the config while setting it too...

[summer scroll]

Thanks, F3 + B is Hitbox, the tooltips is F3 + H

[tidal skiff]

oh true

lol didnt think about that

[tacit drift]

well, there is also the server brand

ofc you can't change the client brand

[spiral light]

You can change the server brand in F3 but it is sended in the moment the player joins ... So you need to catch the packet there and modify it

[sage dragon]

I wonder if it is possible to check where an arrow hit a player?

[onyx fjord]

there is a plugin to hide that

https://www.spigotmc.org/resources/packetwhitelistnbt.98418/

[spiral light]

Like the height or the back/front/left/top?

[sage dragon]

I'd say the height would be enough.

Like... is it in the player's head, or in his legs

[spiral light]

Not that easy and not accurate all the time but it is possible

[tidal skiff]

does getOfflinePlayer work even if the player is online

i get that it says offline player

but i just need to know so i can get the uuid

[spiral light]

Yes

[sage dragon]

Yeah, but it will give you the online player

[tidal skiff]

alr ty

[sacred mountain]

anyone know anything about effectlib

im having trouble doing some stuff

i dont know where to add parameters into the code after reading the wiki

[tidal skiff]

anyone know why UUID tempID = Bukkit.getOfflinePlayer(getConfig().getString("Traps.ExplosiveTraps." + iter + ".PlacedBy")).getUniqueId(); isn't working? the error says that its returning null even though it shouldnt be, i can literally see it there in the config

[sage dragon]

Just curious... Why exactly don't you just save the uuid in the config?

[tidal skiff]

i do but if u try set tempid directly as the string in there it rejects it

[sage dragon]

Did you try UUID.fromString, or did you just put a string there?

[tidal skiff]

i just put the string there

[sage dragon]

If you use Bukkit.getOfflinePlayer with a string, it's assuming you entered a name, not a uuid

[tidal skiff]

whats fromstring

[tidal skiff]

oh really?

thats not sarcastic

it looks sarcastic

[sage dragon]

UUID.fromString(yourUuidAsAString)

[sage dragon]

No, it's not sarcastic

[tidal skiff]

OMG IT FINALLY WORKS

holy crap if i'd known the from string function existed

tysm

[sage dragon]

You're welcome

[tidal skiff]

is anyone on mc 1.18.1 rn? i need u to hop on the server so i can test smth itll be like 2 seconds

How can I send the crack animation to a few blocks at the same time? everytime I send a new crack animation the previous one disappears..

[quaint mantle]

Hello! I am trying to disable the fact that a tripwire gets powered when you step into it.

I looked at the spigot source in buildtools and here is what I found (it's from CraftBukkit):

        // CraftBukkit start - Call interact even when triggering connected tripwire
        if (flag != flag1 && flag1 && (Boolean)iblockdata.get(ATTACHED)) {
            org.bukkit.World bworld = world.getWorld();
            org.bukkit.plugin.PluginManager manager = world.getCraftServer().getPluginManager();
            org.bukkit.block.Block block = bworld.getBlockAt(blockposition.getX(), blockposition.getY(), blockposition.getZ());
            boolean allowed = false;

            // If all of the events are cancelled block the tripwire trigger, else allow
            for (Object object : list) {
                if (object != null) {
                    org.bukkit.event.Cancellable cancellable;

                    if (object instanceof EntityHuman) {
                        cancellable = org.bukkit.craftbukkit.event.CraftEventFactory.callPlayerInteractEvent((EntityHuman) object, org.bukkit.event.block.Action.PHYSICAL, blockposition, null, null, null);
                    } else if (object instanceof Entity) {
                        cancellable = new EntityInteractEvent(((Entity) object).getBukkitEntity(), block);
                        manager.callEvent((EntityInteractEvent) cancellable);
                    } else {
                        continue;
                    }

                    if (!cancellable.isCancelled()) {
                        allowed = true;
                        break;
                    }
                }
            }

            if (!allowed) {
                return;
            }
        }
        // CraftBukkit end

As you can see, cancelling PlayerInteractEvent and EntityInteractEvent should be enough

    @EventHandler
    public void tripwireEvent1(PlayerInteractEvent event) {
        event.setCancelled(true);
        Logs.logInfo("triggered 1");
    }

    @EventHandler
    public void tripwireEvent2(EntityInteractEvent event) {
        event.setCancelled(true);
        Logs.logInfo("triggered 2");
    }

Unfortunately, this code doesn't seem to work: event is not triggered when I step into a string (it is if I click on it of course)

Any idea why?

[trim crystal]

I'm not sure never dealt with this but I can only give what I think can be the solution.

Try saving the entity the player is interacting with and save it as a tripwire, after that change the tripwire's state

[quaint mantle]

What entity are you talking about?

I am trying to understand why the event is not triggered

[trim crystal]

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        Player p = e.getPlayer();
        if (e.getAction() == Action.PHYSICAL) {
            if (e.getClickedBlock().getType() == Material.TRIPWIRE) {
                p.sendMessage("you hit a trap!");
            }
        }
    }

I think you can change it to any entity as well

[quaint mantle]

This won't help, as I said it is not triggered

[trim crystal]

dumb question but, did you register the listener?

[quaint mantle]

yes, as I said it works if I click on it

[trim crystal]

Happens to me a lot that's why I'm asking

PlayerInteractEntityEvent try using this event maybe

[quaint mantle]

This event is not triggered according to the code I sent

[quaint mantle]

here

Tripwires are not entities

[trim crystal]

Yeah now I understand, it's pretty weird since it even says "If all of the events are cancelled block the tripwire trigger, else allow"

[summer scroll]

Does someone know what is the probable cause here? So I make armor stand follow player's head movement, and suddenly the armor stand stops following player's head movement when player is riding something.

[quaint mantle]

yeah exactly

do you know where I could report this issue to spigot team?

[trim crystal]

The armor stand rotates the same angle your head does but when you get on the horse your head rotates to the horse's head and the armor stand doesn't that's when the problem is starting.
Try rotating the armor stand to the horse's head angle when the player gets on it

[trim crystal]

Not sure, maybe try tagging one of them

Does mining fatigue -1 let's the player hand animation move the same speed without actually breaking the block?
in 1.8 it used to work but I'm now using 1.18

[summer scroll]

The player follow horse head movement?

[trim crystal]

The head's angle changes to the horse's head angle but the armor stand stays according to the player's head angle before you get on the horse

[summer scroll]

Okay, I'll try to use the horse's yaw.

[trim crystal]

can anyone help me?

[quaint mantle]

why not trying?

[trim crystal]

I actually asking because I tried maybe it doesn't work anymore and maybe I did something wrong..

    public void addSlowDig(Player player, int duration) {
        player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW_DIGGING, duration, -1, false, false), true);
    }

that function gives the player the mining fatigue and I do receive mining fatigue ingame

[cold field]

When is the itemMeta of an ItemStack null?

[trim crystal]

Hey, how can I put the equivalent to mining fatigue -1 of 1.8 in 1.18?
I want the player to move the hand like he is mining but won't actually damage the block, I know I can cancel block damage event but on the client side he will break the block..

[tardy delta]

cancel the block break?

well that will still show the block breaking

[trim crystal]

In 1.8 I could give the player mining fatigue -1 and the hand would move the same speed but he won't damage any block.. I think they removed that in 1.18

[spiral light]

In 1.18 you can send block damage to 0 all the time

[trim crystal]

with the player.sendBlockDamage(location, 0f);?

currently I'm using this but to change the animation, I'll send you the code, 1 sec

    private ArrayList<CustomBlock> blocks;

    @Override
    public void onEnable() {
        this.blocks = new ArrayList<CustomBlock>();
        getServer().getPluginManager().registerEvents(this, this);
    }

    private CustomBlock exists(Location location){
        for(CustomBlock block : blocks){
            if(block.location.equals(location)) return block;
        }
        return null;
    }

    @EventHandler
    public void onInteract(PlayerInteractEvent event){
        Location location = event.getClickedBlock().getLocation();
        CustomBlock block = exists(location);

        if(block != null){
            block.incermentDamage(event.getPlayer(), 0.05f);
        }else{
            blocks.add(new CustomBlock(location, 0f));
        }
    }

Main ^^

public class CustomBlock {

    public float dmg;
    public Location location;

    public CustomBlock(Location location, float dmg){
        this.location = location;
        this.dmg = dmg;
    }

    public void incermentDamage(Player player, float damage){
        this.dmg += damage;
        if(dmg < 1f) {
            player.sendBlockDamage(location, dmg);
        }
        else
            player.sendBlockDamage(location, 0f);
    }

CustomBlock^^^

This is just a test so I don't care if the main and the listener are the same class

So with this code if I cancel the interact event the block would break and then it would cancel the break, but on client side it would show the crack animation going all the way

I know I can send the block crack animation through NMS but I couldn't find how..

[spiral light]

Playerinterscct gets called just once

Playerinterscct event*

You will need to check if the player clicks something else and if not send no block DMG all the time

Also mining fatigue 255 will slow down the break animation ?

[trim crystal]

I'll try the mining fatigue 255, but I didn't understood what you said about the playerInteractEvent, currently I'm testing a perfect situation where the player doesn't click anything else, when I long left click the block will break like in vanilla minecraft but since the server cancelled the event the block won't disappear, I don't want the block to even break on client side.

[ivory sleet]

@cold field anyways the code is better

You could still extract the data transfers themselves from the manager logic

[trim crystal]

they don't damage the block but the player's hand is no where to be seen lol

[trim crystal]

Was that meant for me? or EmPee?

[ivory sleet]

Empee

[trim crystal]

I saw people use protocolLib for sending packets, is it better than NMS?

[spiral light]

Yes

i put this together but it doesnt work (regenerateInto = Material.PLAYER_HEAD)

[chrome beacon]

getState returns a copy. To apply your changes call update

[dusty sphinx]

ah

thanks ill try it

[spiral light]

not just update... setBlockState and then update maybe ?

[eternal oxide]

No just state.update()

Applies it back to the Block the state came from

[dusty sphinx]

update works

dope

thanks

[wet breach]

I will review it later if that is ok

however caveat, I will only review it for 1.17+

only because I am not a fan of developing for older versions, however just because I am not a fan of it, doesn't mean I should punish/critique harsher on others for doing so even if I would prefer if the majority of devs would stop supporting outdated versions

if your repo is setup in a way that makes it easy to review code for differing MC versions I will only critique on the code for 1.17 🙂

Just letting you know ahead of time so that when I give you my review it isn't confusing XD

just use a method

to create the recipe

pass in the things that are different from each item to another in the params

[dark arrow]

is it possible that i make a varialbe 'x' thne use it every where in the method then i replace teh x with the string of the item?

u mean like

x as a param?

then just method(x);

btw u shouldnt name variables 1 letters

[wet breach]

pre-login and the reason for this has to do with wait times

if I remember right, in the pre-login phase you can do all the stuff you want to and have a fairly long time to do so before connection gets dropped

and if for some reason the DB stuff isn't able to get fetched for whatever reason you can just terminate the connection

if you did this in the on Join phase, it has the potential of causing the server to lag, and because we already passed some protocol connection stuff, you have a shorter time to do stuff before the server automatically terminates the connection

and if the DB server stuff couldn't be fetched, they could potentially be stuck waiting on the connection to terminate

[cold field]

Ok get it. The problem is that I've used reflection to make it compatible with older version. I really wanted to avoid using reflection for 1.17 (Thanks to nms repackaging) the problem is that some classes has been compiled with java version 16+ and I can't compile the lib with java 8

[tardy delta]

I'm asking again, anyone know what's the equivalent of 1.8 mining fatigue -1 on 1.18?

I want to make it so that the hand animation moves the same as if the player doesn't has a mining fatigue but at the same time that the player doesn't damage the block on client side

[sage patio]

Hi, I have a problem with PlayerInteractEntityEvent
These is my code

public void onInteract(PlayerInteractEntityEvent event) {

        if (!(event.getRightClicked() instanceof Player)) {
            return;
        }

        Player player = event.getPlayer();
        Player target = (Player) event.getRightClicked();

        if (player.getItemInHand().getType().equals(Material.BLAZE_ROD)) {
            if (player.hasPermission("gtautils.cuff")) {
                if (Main.cuffs.contains(target)) {
                    Main.cuffs.remove(target);
                    player.chat("/uncuff " + target.getName());
                } else {
                    Main.cuffs.add(target);
                    player.chat("/cuff " + target.getName());
                }
            } else {
                player.getItemInHand().setType(Material.AIR);
                player.sendMessage(Utils.getColorizedConfig("noPermission"));
            }
        }

    }

      // I have a HashSet of Player in my Main class too

Problem is when I Right click on anyone, plugin runs both if and else codes.

[sage patio]

all of this

[golden turret]

the event is called twice

see event.getHand

[sage patio]

Thanks

[mellow gulch]

that event runs for the mainhand, and then sometimes also the offhand

[sage patio]

So how I can check item in player's hand in another method ?

[mellow gulch]

the event has a getItem() which returns the itemstack in the hand, regardless of which hand it was

[trim crystal]

😔

[sage patio]

umm

[mellow gulch]

wish i could help, i don't remember anything about 1.8, it was quite a long time ago

[trim crystal]

Do you know maybe how I can make sure that the hand moves normally (when you mine) but you don't damage the block, trying to figure it out with protocol lib but I'm not even sure if it'll do the job lol

[mellow gulch]

what are you showing in this image?
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerInteractEvent.html#getItem()

[mellow gulch]

earlier today/yesterday someone was saying something about that sort of thing if you scroll up quite a bit.

[sage patio]

Its a short time I started to coding, so ...

[golden turret]

*PlayerInteractEntityEvent

[trim crystal]

I think it was someone trying to help me lol

[mellow gulch]

ok, event.getItem() will return an instance of an Itemstack

[golden turret]

use

PlayerInteractAtEntityEvent

[spiral light]

what

[golden turret]

the getHand

[trim crystal]

I answered this

[tardy delta]

unnessecary check
if (Main.cuffs.contains(target)) {
Main.cuffs.remove(target);

cuffs.remove(target) will return a boolean whether or not it can be removed or not

[sage patio]

thanks

[sage patio]

like this ?

[tardy delta]

dont try to remove two times

it will check if it contains and remove it

[trim crystal]

Can anyone help me understand protocol lib? I'm reading the wiki and having a bit of a issue understanding

[hybrid spoke]

what is cuffs?

[spiral light]

what exactly is the problem ?
you create the packet, write the data that the packet needs and then send it ...

the mining speed penalty ?

you cant

unless you add some speed / break the block before it should break with calculations ...

[trim crystal]

In the wiki they give packet ID, how do I use that ID?

[tardy delta]

i'm having a player field somewhere in a class that extends bukkitrunnable, when the user leaves the server the runnable will be cancelled, will it be able to be gc'd?

[hybrid spoke]

manipulate packets

[hybrid spoke]

why shouldnt it?

[spiral light]

what id do you talk about ?
i think it is the packet-id that identifies the packettype

[tardy delta]

also because its an inner class

[hybrid spoke]

doesnt matter

inner classes are like normal ones just.. inner.

[tardy delta]

and that outer class instance is stored in a map

[trim crystal]

I see, so for example if the wiki shows "Packet ID 0x09" it doesn't really concerns me right?

[tardy delta]

until the player leaves

so it was a bit weird

[hybrid spoke]

inner class just means that it belongs to the scope of the outer class

[spiral light]

not rly

[tardy delta]

yea i know

i think that helped me

[sage patio]

a HashSet of Player in Main class

[tardy delta]

dont make fields public tho

[hybrid spoke]

so remove the second remove

[spiral light]

why tho

[sage patio]

I did thanks, but the main problem isn't solved yet

[tardy delta]

you dont want to expose them

[spiral light]

ok you mean for public uses ...

[hybrid spoke]

your problem is, that it runs once per hand

check if the hand is of OFF_HAND and return if so

[trim crystal]

https://prnt.sc/24o9pun
In protocollib if I have this packet, to change the ID I do:
packet.getIntegers().write(0, 1)
and to change the stage I do:
packet.getBytes.write(0, (byte) 1)
or did I understood in incorrectly, because if I didn't then how do I change the location?

[hybrid spoke]

what he's trying to say is, that there is a thing called encapsulation which belongs to OOP

having public fields in such a context breaks the concept of OOP kinda

[trim crystal]

Sorry for asking too many question about this I just feel a bit lost here XD

[tardy delta]

packets are a pain

[spiral light]

in general a good idea but not important for private usages tho

its a nice to have

[sage patio]

I used player.getInventory().getItemInMainHand().getType().equals(Material.BLAZE_ROD) to check item in player's hand, and if it will run twice for each hand, the off hand is empty of BLAZE_ROD, so I don't understand why

[hybrid spoke]

it is. its like having 3 lego stones but not stick them together

bad metaphor but the point should be clear

[spiral light]

position is mostly 3 integers ... so maybe setInteger(1,x),setInteger(2,y), setInteger(3,z)

[tardy delta]

i'm always thinking if you really want to use something as obj.myfield make it like a method so you can call obj.field()

[hybrid spoke]

the event provides a #getHand() method and you are just checking the mainhand. when the offhand is called, the mainhand still has the item

[tardy delta]

but yea i'm doing strange things sometimes

[trim crystal]

I see, thanks.. I do think it's doubles as seen here: https://dev.bukkit.org/projects/protocollib/pages/tutorial on the sending packets section

just create a method that does some stuff and call it

[buoyant viper]

like sendBlockBreak or sendBlockDamage

[dark arrow]

i am making a code so that if i add diamond blocks around the diamond armour and it should give the armour with prot5 and that part is working but how will make into method thats the problem

cuz as far as i know we can put variable in method

and armour is a defined funtion

[tardy delta]

Player#sendBlockDamage?

[patent horizon]

where do gradle builds get output to?
maven usually outputs it in a target folder in the project

[trim crystal]

There is but it can show only 1 block at a time and you need to do it per player, so if I want to show 10 block that are half broken to 2 players well.. you can't with that

I'm suffering lol

been trying to figure this out all day

[dark arrow]

instead of ItemStack item = new ItemStack(Material.DIAMOND_HELMET)

what should i w rite in teh mothod

so that i could replace the called method with the armour i need

[buoyant viper]

maybe its BLOCK_BREAK_ANIMATION? @trim crystal

https://github.com/dmulloy2/ProtocolLib/blob/master/src/main/java/com/comphenix/protocol/PacketType.java#L115

that matches up with the 0x09 packet id

[trim crystal]

Thanks, I'll check it

[tardy delta]

take a material as argument?

[trim crystal]

Yeah I figured I wrote the incorrect packet

[buoyant viper]

rip

i think u were also sending a client packet from the server so

lol

or trying to

[trim crystal]

oh lmao, I'm pretty new to this XD

Gives me this error everytime I interact with a block

[buoyant viper]

on phone cant see that

[trim crystal]

oh lol, I have this line as well: [ProtocolLib] Loaded class RPrison.rprison.Rprison from Rprison v1.0-SNAPSHOT which is not a depend, softdepend or loadbefore of this plugin.

[dark arrow]

?

[trim crystal]

Caused by: com.comphenix.protocol.reflect.FieldAccessException: No field with type byte exists in class PacketPlayOutBlockBreakAnimation.
This is the main error here

[buoyant viper]

uhh

maybe try writing in the order of packet fields on wiki? idk

so write the int, then the location(x3 doubles, or int depending on how it wants loc?), and then the byte

never used protocollib either so shots in the dark rn

[trim crystal]

lmao let's see if that works

nope, didn't change a thing

[buoyant viper]

rip

[trim crystal]

yep XD

[hexed hatch]

will Entity#remove function even if the entity is not in a loaded chunk?

[tall dragon]

Entity#remove marks it for deletion

which will not happen in an unloaded chunk

[tardy delta]

is the String::replace to prevent SQL injection?

String statement = "SELECT * FROM playerdata WHERE player_id='{id}'";
            pStatement = connection.prepareStatement(statement.replace("{id}", uuid + ""));```

[trim crystal]

just posted a thread on the forum.. let's hope someone will save me lol

[candid galleon]

das not how prepared statements work

[tardy delta]

tell me how to do then

its not my code tho

[grim ice]

;listen

just

learn java

okay

u wouldnt need to waste time for such a simple task if u knew java

private void nameThisWhatever(Material material) {}

actually replace void with the class name

was it shaped recipe

or smth

wait nvm

[trim crystal]

Is there anyone here that knows how to use protocollib?

[chrome beacon]

Yeah

[tardy delta]

how would i save a list of channels (strings) in a database?

i was thinking of saving it as one string with a delimiter

i could make a new table with channels and inner join it with the users, goes kinda brrr

[patent horizon]

.

[tardy delta]

does this looks clean lol

public User getUser(UUID uuid) {
        return userCache.values().stream().filter(u -> uuid.equals(u.getUuid())).findFirst().orElseGet(() -> {
            String sql = "SELECT * FROM playerdata WHERE uuid='" + uuid + "'";
            try (Connection conn = Database.getInstance().getDatasource().getConnection();
                 PreparedStatement ps = conn.prepareStatement(sql)) {
                ResultSet rs = ps.executeQuery();
                if (rs.next()) {

                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
            return null;
        });
    }

userCache is a map<uuid, user> tho

[sudden raft]

even if uuid is UUID, i would recommend using PreparedStatement#setString instead of concatenating

[tardy delta]

oh uh lets assume its better

[sudden raft]

also userCache.values().stream().filter(u -> uuid.equals(u.getUuid())).findFirst() time complexity is O(n) (linear)

instead, you could use uuid as key

[tardy delta]

so like this and then replace it
String sql = "SELECT * FROM playerdata WHERE uuid='?'";

xd i was trying to do some stream stuff

ah i can remove the ' '

also whats the best way to save a players playtime to a db? rn im saving an int with the total minutes they have played since they joined?

[peak granite]

if i have a home list in a player data file like this:
Homes:
HomeName:
Location: ....
AnotherHomeName:
Location: ....
how do i get the amount of homes, when i do getStringList(Homes).size() it returns 0

[tardy delta]

its not a list

a stringlist == ```yaml
key:

• 'value1'
• 'value2'```

do getConfiurationSection("homes").getKeys(false).size()

[hexed hatch]

is there no api for leashing entities to fenceposts?

I can get the leashholder entity

but I can't do anything with the api equivilent to this: /summon pig ~ ~ ~ {Leashed:1b,Leash:{X:32,Y:32,Z:32}}

[grim ice]

Yes

[tardy delta]

also is it possible to return in a HashMap::forEach?

doesnt work so i guess no

Map.Entry goes brr

[buoyant viper]

lambda expressions do have their caveats

[tardy delta]

true

[formal bear]

ik its about java not exactly spigot, but how to make timeout, like 1 second after

[peak granite]

runtasklater

[tardy delta]

isnt that a responsability for the fence or the leash itself?

[spiral light]

playerConnection now is "a" or smth like this

[buoyant viper]

sounds like a remap issue

[spiral light]

i think he does not use the mojang remappings ...

[tardy delta]

best move

efficiency is something else i guess xd

[brave sparrow]

Since userCache is a map you should just do userCache.get(uuid)

The whole point of a hashmap is the key based access

[tardy delta]

BRRUUHHHHH

im stupid

[brave sparrow]

Otherwise you could just be using a list

[tardy delta]

did i just....

do this..

bruhh its because it was an arraylist first and i didnt change it

[sudden raft]

you could also use computeIfAbsent

[brave sparrow]

The .get() is the main reason to use a hashmap, it gives you amortized constant time access by key

You wouldn’t want to use computeIfAbsent here

[sudden raft]

return userCache.computeIfAbsent(uuid, k -> {
// execute query to database
return user;
});

my english is broken

[tardy delta]

yea i understand 😄

sometimes i'm just doing suck stupid things

[brave sparrow]

Are you synchronizing access to userCache

Or how are you maintaining thread safety

[tardy delta]

i'm not using it on multiple threads

[brave sparrow]

You’re doing database calls on the main thread??

[tardy delta]

yea i was planning to do it async

[brave sparrow]

You have to do it async

[tardy delta]

still implementing db stuff

[sudden raft]

I think using a ConcurrentHashMap is enough to make it threadsafe

at least in this case

[brave sparrow]

I mean, using a sledgehammer to kill a fly

[digital rain]

hey why is the default player inventorytype crafting instead of player, ig its intended but its a bit weirdly described on hub.spigot

[brave sparrow]

But yeah lol

[wet breach]

depends on the object being stuffed into that kind of hashmap, but for the most part yes that type of hashmap is threadsafe

[brave sparrow]

There’s performance trade offs to using concurrent hashmap

[tardy delta]

i'm storing an <uuid, user> where user is a player wrapper

[wet breach]

most people really don't have to worry about that though

[brave sparrow]

If you don’t do it async then any time a database call takes any amount of time, which can happen often, your server is going to time out

[brave sparrow]

Good practice is good practice

[wet breach]

in this case that doesn't really apply here

what I mean is while there is trade offs with ConcurrentHashMap, most of the time you are going to see performance boosts

not the the other way around unless you are stuffing a crap ton of data into it

[young knoll]

IIRC you only need to use the concurrent one if you are modifying it from multiple threads

Reading is fine

[wet breach]

yes I was stating earlier above confirming to someone that it was thread safe

[quaint mantle]

no

Reading can cause a write operation as well

[brave sparrow]

No it can’t

If there’s a write associated with your read then it isn’t a read

However

You do have to worry about synchronization when reading from multiple threads if there are writes happening

And in this case there would be writes happening

[quaint mantle]

thats a myth; reading is not always thread safe. If you read and write at the same time, it will cause cme

[brave sparrow]

Reading isn’t always thread safe but reading does not cause a write

[wet breach]

concurrenthashmap takes care of that, this is the exact reason it was created in the Java API

[brave sparrow]

ConcurrentHashmap does a hell of a lot more than synchronization, it will do the job here but again, it’s using a sledgehammer to kill a fly

I’m not disputing that it will work

It’s just unnecessary

And there’s also memory overhead to think about if you don’t configure it with an appropriate concurrency level for your use case

[formal bear]

why is it highlighted?

[hexed hatch]

anyone know if there's an event for cancelling spectating an entity?

[brave sparrow]

Hover over the highlighted section and see what it says

[peak granite]

when i do config.set("Homes", null); it doesn't truly set Homes value to null in config like Homes: {} how can i make it actually set

it just skips

[brave sparrow]

https://www.spigotmc.org/threads/event-when-spectator-player-takes-mob-player-view.282839/#post-3038291

[brave sparrow]

Homes: {} wouldn’t be null, there’s no bracket syntax like that in YAML

[hexed hatch]

I was using that and it lead me to nothing. Through testing, I learned that the only way to check for that is to use PlayerToggleSneakEvent

Which is absolutely sickening to me

but it does work

[brave sparrow]

Lol

Hacky solutions always make my soul hurt but they get the job done

[flat belfry]

damn alex from mp

Do you just handle java

[buoyant viper]

whats java

[brave sparrow]

Technically I do both but my main focus is Java

I don’t think this is the right channel for that though lol

[wet breach]

all these things are not something to be concerned about for most plugins unless they are dealing with a bunch of data

sure, you could think about it and what not, but better to design and getting it working first then to sit there and think about which API method in Java is more optimal to use

[brave sparrow]

Designing it properly from the beginning is the way to avoid something like that becoming an issue later and then being forced to redo a bunch

Just jumping into something without thinking it through is how you make a mess and accumulate a massive amount of technical debt very quickly

[wet breach]

there really is no way to design something properly from the beginning not usually

you end up in just a dev cycle if you attempt that

and never release 🙂

[brave sparrow]

There’s a difference between not designing every component before you start and not designing anything before you start lol

This is a simple thing to think about

[naive jolt]

Hey, is there a work around to getting access(in another class) to this player, in the event

public void DamageEntity(EntityDamageByEntityEvent event) throws IOException {
       if(event.getDamager() instanceof Player) {
           Player damager = (Player) event.getDamager();

       flagCount.get(damager.getName());```

the damager var

[fleet imp]

I'm referencing getConfig() in an interface that doesn't have a static modifier. It gives me a problem: Non-static field 'config' cannot be referenced from a static contex

[brave sparrow]

That event is going to be called a bunch of times, what are you actually trying to do WRT getting the entity from another class

[wet breach]

well we obviously have differing opinions. I am of one that will answer your questions and tell if you something will work and what not, however not really my job to inform and teach nuances of the Java API which is where you seem more concerned with 🙂

You don't become a good developer by not making mistakes

[brave sparrow]

You can make mistakes, or you can get some wisdom from somebody who has already made the mistake and can teach you the lesson directly

The end result is the same

[delicate cargo]

how can i shift a location forwards>

[brave sparrow]

Location#add

[delicate cargo]

i mean on 1 dir

[brave sparrow]

Would need to see the code to give you a specific answer

[brave sparrow]

Add can take a vector direction

[delicate cargo]

so like shift forwards relative to player rot

[trim crystal]

I'm here again with the same issue trying to get help lol
https://www.spigotmc.org/threads/protocollib-error.539678/

[wet breach]

not quite, unless the mistake is going to kill someone or harm someone I agree, however you tend to remember better by being allowed to do something wrong and learning from your own mistake as opposed to someone else's mistake and never understanding why fully the other way is bad in some way

[brave sparrow]

Can we get line numbers?

[fleet imp]

Context: I'm making a discord bot that runs when the plugin runs

public class Main extends JavaPlugin {
    private final YamlConfiguration config = (YamlConfiguration) this.getConfig();
    public interface yml {
        String BotToken = config.getString("BotToken");

[trim crystal]

Sorry, how can I do that?

[delicate cargo]

just seeing vector to add

[wet breach]

but like I said we obviously have differing opinions which that is ok

[brave sparrow]

Well specifically the line number for the referenced bit of the error would be helpful

[wet breach]

and not necessarily need to debate our differences XD

[buoyant viper]

his issue iirc was not having the right fields for BlockBreakAnimation

[trim crystal]

If you mean this error RPrison.rprison.Rprison.onInteract(Rprison.java:52)
Then it's write(3, location.getBlockZ() + z);

[brave sparrow]

I buy that

[brave sparrow]

?

[delicate cargo]

im just seeing loc.add(vec)

aka add a vectors coords to a loc

[brave sparrow]

Correct

A vector is a direction

[delicate cargo]

oh

oh damn i understand it now

its not rotational values

[trim crystal]

If it's for me, I've tried a few ways to get to the correct fields, I'm using the fields according to: https://wiki.vg/Protocol#Block_Break_Animation

[naive jolt]

for this hasmap

 if(p.hasPermission("HyperCheat.checkFlags")){
               if (args.length == 0){

                   p.sendMessage(flagCount.get(damage.getPlayername) + " is the amount of flags" + p.getDisplayName() + " has.");```

[delicate cargo]

but instead the shift needed for moving forward

[brave sparrow]

Rotational values can be used in conjunction with a Location to compute a vector direction

If you just want to use the player’s direction there’s methods for that

[brave sparrow]

Is that being called in a command or?

[naive jolt]

yes

it is

[brave sparrow]

So are you just trying to show them their own flags?

You don’t need to fix it, see where it says “Usually this is not harmful and you can skip these warnings”

[young shell]

I know that I don't need to fix it. I don't like the warning tho

[brave sparrow]

I’m guessing the error is on that config.getString() call?

[trim crystal]

@brave sparrow do you know how I can know the correct fields? the main issue is the location..

[buoyant viper]

gradle, on the other hand, flips its sh!t over something like duplicate files

or at least it did for me

[naive jolt]

Yes

so I need to supply the Player

but then the player is in that Event

as a local variable

[brave sparrow]

The player is the sender of the command

[formal bear]

Name of the plugin: should be main class? Which "name"

[brave sparrow]

There’s no double field in the wiki vg section you linked

There’s VarInt, Position and byte

So those are the fields you have to set

[buoyant viper]

wouldnt position be 3 doubles tho?

[brave sparrow]

It would

[buoyant viper]

or maybe 3 ints if its picky

[brave sparrow]

But you can’t just set position to 3 doubles

[trim crystal]

How can I get to the position? as I saw there are only:
getDoubles();
getFloats();
getIntegers();
getBytes();
didn't see anything to position so I could write on..

[brave sparrow]

I’m not super familiar with the protocol lib methods but according to your error that is the issue

Maybe see what Position is made up of

[brave sparrow]

Is this code inside your main class?

[brave sparrow]

The player is in the command itself as the sender, the event has a variable and the command execution has a variable and they both point to the same thing

The command doesn’t need to reference the event

[trim crystal]

Yeah I'm trying a few things, thanks 😄

[fleet imp]

but whats wrong with it

[naive jolt]

The player your getting the flags of is not the player from that event

/flags another player

[wet breach]

https://wiki.vg/Protocol#Position

to learn more how position is comprised

[buoyant viper]

found this for u msybe @trim crystal https://www.spigotmc.org/threads/protocollib-nms-how-to-use-block-break-animation-packet.442335/

[naive jolt]

Here's the code

if (sender instanceof Player p){
            HashMap<String, Integer> flagCount = damage.getflagCount();
           if(p.hasPermission("HyperCheat.checkFlags")){
               if (args.length == 0){

                   p.sendMessage(flagCount.get(damage.getPlayername) + " is the amount of flags" + p.getDisplayName() + " has.");
               }else{
                   Player target = Bukkit.getPlayerExact(args[0]);
                   if (target instanceof Player){
                       p.sendMessage(flagCount.toString() + " is the amount of flags" + target.getDisplayName() + " has.");
                   }
               }

           }else{
               p.sendMessage(ChatColor.RED + "You do not have the required permissions(HyperCheat.checkFlags) to use this command");
           }

        }```

[wet breach]

unlike in game where you are used to xyz, it is in the packet as xzy @trim crystal

[brave sparrow]

If it’s another player then you would use Bukkit#getPlayer with the command argument

Still not the event

[wet breach]

26 bits for x and 26 bits for z, y having only 12 bits

[naive jolt]

How do I use Bukkit#getPlayer to get the player in the event from the other class

[wet breach]

((x & 0x3FFFFFF) << 38) | ((z & 0x3FFFFFF) << 12) | (y & 0xFFF)
from wiki.vg they give you an example to encode it properly

[brave sparrow]

You’re linking the command to the event which isn’t what you want

The player in the event is totally irrelevant to the player in the command

[naive jolt]

Okay let me explain a bit more

[brave sparrow]

Even if it’s the same player

[formal bear]

i found the solution, nvm! its inside other class thats why its not working

[brave sparrow]

It’s ok for it to be inside another class, you just have to give it the instance of your main class

[wet breach]

Hey, thanks alot! it worked for me, been looking for this all day lol

[trim crystal]

Yeah apparently it's BlockPosition blockPosition = new BlockPosition(new Vector(b.getX(), b.getY(), b.getZ()));

[formal bear]

yeah

[naive jolt]

So I should get the player supplied in the command

[brave sparrow]

Exactly

[wet breach]

If you are using protocolLib yes

[trim crystal]

❤️

[buoyant viper]

np

[wet breach]

how protocolLib does stuff isn't the same from the wiki.vg

so you need to refer to their API stuff

ProtocolLib attempts to make it easier instead of messing with stuff like I was showing for example

[buoyant viper]

just wasnt sure what the position field was for protocollib

[brave sparrow]

Nested interfaces in Java are static by default

[buoyant viper]

but that byte field might yell at u since that spigot page showed int

[wet breach]

I didn't realize protocolLib was being used here otherwise I wouldn't have bothered referencing wiki.vg stuff XD

[buoyant viper]

his original message showed protocollib code lol

[fleet imp]

how do i make it non-static

[wet breach]

well then that is my bad

[buoyant viper]

yea it was uhh

[buoyant viper]

.

[brave sparrow]

You can’t. Interfaces can’t have member values so they can’t be non static when nested

@fleet imp you’re providing too much implementation for a Java interface

All the interface really includes is method signatures

The implementation comes from implementing classes

[fleet imp]

how to i convert a string to int or bool

[spiral light]

Integer.parse###

same for bool

[loud vessel]

Integer.parseInt(string)
Boolean.parseBoolean(string)

[fleet imp]

thx

[lyric grove]

Hi, im getting a npe although i dont see why i am

as i made sure i set it if absent

[buoyant viper]

is actions null?

[lyric grove]

no

[buoyant viper]

thats just a class

i mean the actions field

[lyric grove]

i set the action as a new linked list so yeah

[buoyant viper]

still not what i'm talking about

this.actions

the field, actions

[loud vessel]

Output this.actions to the console to understand that it is not null

[buoyant viper]

is that null?

[lyric grove]

oh no i save it on disable and load it onenable

[brave sparrow]

Is an exception being thrown in your loadActions()?

If so actions would never be assigned

[lyric grove]

there isnt any exeption

and actions are being assigned, idk why its giving me a npe when i try to access them

(i store it using json)

[brave sparrow]

Is there any more to the error?

[lyric grove]

I dont think so

[brave sparrow]

Ok, can we see the whole getFromUUID with line numbers?

[lyric grove]

yeah

[brave sparrow]

Right before line 55 can you throw in a system print outputting this.actions

[buoyant viper]

can you add a System.out.println("" + actions) before calling the return in getFromUUID

[lyric grove]

ok

[buoyant viper]

or like an

if (actions == null) System.out.println("uhoh");

[young shell]

shouldn't Javaplugin#saveDefaultConfig() create a Folder with the plugin name and the config file inside?

If you’ve set up config defaults it should

So if the config File is inside the resources folder right?

[tardy delta]

yes

[lyric grove]

oh what? actions is null

well rip, i did something wrong

[cold pawn]

I’m making a chat plug-in we’re it gets the players around a player and sends the message that the player sends only to them. Practically Proximity chat. I’ve tried using the distance method in the players location and the getNearbyEntities Method but they don’t seem to work. It doesn’t give me any errors in console it just doesn’t get the players around that specific player. Any other way I can do this? 😅

[hasty prawn]

Entity#getNearbyEntities

[young knoll]

Nah

[hasty prawn]

And then filter to Players

It works

[young knoll]

You probably want to use distanceSquared for something like this

[cold pawn]

That’s what I did

Didn’t work

[hasty prawn]

What's wrong with getNearbyEntities

[hasty prawn]

Show what you're doing

[hybrid spoke]

"that doesnt seem to work" - what exactly? provide code

[young knoll]

Nothing, but when you want a big radius and only players its probably more efficient to loop over all players in that world

[hasty prawn]

Proximity Chat usually isn't that large of a radius

Guess it depends on what you define as a large radius

[young knoll]

Like, 50

[hybrid spoke]

looping over the players will be more performant

[hasty prawn]

Yeah that's pretty big for prox chat

[cold pawn]

I’m not at my computer at the moment but I loop through all the entities around that player, I then check if there an instance of a player after I add them to the recipients list. The issue is it doesn’t do the check and just gets everyone anyways...

And I clear the recipients list before

[hybrid spoke]

so you are doing smth wrong

[hasty prawn]

^

When you're back at your computer send code

[young knoll]

We can’t really so much without the code

[cold pawn]

Ok then I’ll do that in a bit 😅

[fleet imp]

how do i send text to chat with a plugin

[young knoll]

To one player? All players?

[fleet imp]

all

[young knoll]

Bukkit.broadcastMessage

anyone know why actions would be null even when im loading it?

[young knoll]

If logfileroot already exists you don’t load anything

[buoyant viper]

^

[lyric grove]

omg thank you so much i hope this works

[wide flicker]

Anyone know how to force a plugin to use a dependency packed with it instead of the version packaged with the server? (Gson version used is about 5 years out of date; trying to use the latest version, but it seems to be sticking with the server provided copy...)

[young knoll]

Shade and relocate it and it should be used

[vocal cloud]

Yeah if you shade it it will use internal dependencies.

[young knoll]

Relocate is the important part

Gotcha, I'll look into it. Thanks!

I currently do this with metadata as such java if (!isUsed(belowLoc.getBlock())) { event.getPlayer().sendMessage("hasnt been used"); event.getPlayer().setVelocity(event.getPlayer().getVelocity().setY(1.2)); belowLoc.getBlock().setMetadata("UsedOnce", new org.bukkit.metadata.FixedMetadataValue(Trampotdi.getInstance(), true)); } else { event.getPlayer().sendMessage("has been used"); event.getPlayer().setVelocity(event.getPlayer().getVelocity().setY(1.2)); belowLoc.getBlock().setType(Material.AIR); }

In chat I see both hasnt been used and has been used

the block instantly deletes, any idea how to fix?

the isUsed function if youre curious public boolean isUsed(Block b) { List<MetadataValue> metaDataValues = b.getMetadata("UsedOnce"); for (MetadataValue value : metaDataValues) { return value.asBoolean(); } return false; }

The event gets called a lot

Make sure the event isn't triggered twice or more by adding a cooldown for exemple. With your code, the PlayerMoveEventwill be triggered multiple times
(When the player velocity is updated, the player move again, triggering the event, that make the player move again, etc.)

So it’s getting called twice when the player steps on it

Yeah, im seeing that I put the from and to methods location's to strings. I guess a cooldown is nessasry
