[tender shard]

I don't know, can't you guys just look at the code I sent lol

[grim ice]

it doesnt explain much

[vale ember]

i made typo, it should actually be deserialize since it turns Map into T

[tender shard]

and how would that MapSerializer instance know which constructor to call?

it should of course work with all classes, not only those that I registered somewhere. But anyway, there is other way than what I'm currently doing unless Constructors could be declared in interfaces or abstract classes, which at least they can't as of java 17

public class Question extends MapSerializable {

    @Getter private final String question;
    @Getter private final Answer answer;

    public Question(String question, Answer answer) {
        this.question = question;
        this.answer = answer;
    }

    public Question(Map<String,Object> map) {
        this.question = YamlUtils.getString(map, "question");
        this.answer = new Answer(YamlUtils.getStringList(map, "answers"));
    }

    @Override
    public Map<String, Object> serialize() {
        return new MapSerializable.Builder().put("question",question).put("answers",answer.getCorrectAnswers()).serialize();
    }
}

For example this. If I remove the Map constructor, it still compiles fine, but then throws an exception when trying to deserialize it. And that's what I want to avoid

[vale ember]

public class QuestionDeserializer implements MapDeserializer<Question> {
  public Question deserialize(Map<String, Object> map) {
    return new Question(map.get("question").toString(), new Answer(YamlUtils.getStringList(map, "answers")));
  }
}

[lost matrix]

Spigot does this via reflections

[lost matrix]

This needs a runtime type context to work

[vale ember]

wdym?

[tender shard]

I know, me too

[lost matrix]

If you have a centralised registry for (de)serialisation then it needs to know the type it is deserializing in order to know which MapDeserializer to use.

Anyways i didnt read through the whole convo. Do you guys want to implement marshalling?

[granite owl]

why arent mob spawners holding PDC values i add to them?

mob spawner itemstacks

[tender shard]

I simply want this to work without reflection. I want to declare that every MapSerializable has a constructor that takes a Map
https://paste.md-5.net/wemonitiji.java

[lost matrix]

They do

[vale ember]

yep, of course, it's impossible to deserialize a yaml/json or anything else without knowing the type of the object you are trying to deserialize

[granite owl]

at least not displaying

[tender shard]

are you setting back the itemmeta to the itemstack?

[granite owl]

sec lemme give u the code

its a debug mess but its working

public static void breakMobSpawner(BlockBreakEvent event)
    {
        Block block = event.getBlock();
        Player player = event.getPlayer();
        
        if (block != null && player != null)
        {
            if (block.getType() == Material.SPAWNER && player.getGameMode() != GameMode.SURVIVAL)
            {
                Bukkit.broadcastMessage("TEST");
                ItemWrapper wrapper = new ItemWrapper(new ItemStack(Material.SPAWNER, 1), null);
                
                wrapper.setItemString("test", "LEMAO");
                
                ItemMeta meta = wrapper.getItemStack().getItemMeta();
                
                meta.setDisplayName("LUL");
                
                wrapper.getItemStack().setItemMeta(meta);
                //wrapper.setItemBytes("block_data", NonReflectables.serializeBukkitObjectToByteArray(block.getBlockData().getAsString()));
                
                block.getWorld().dropItemNaturally(block.getLocation(), wrapper.getItemStack());
            }
        }
    }

result is 1 NBT flag

the name

setItemString is a wrapper method to set PDC values

its working in alot of my other methods

[lost matrix]

Well then your wrapper doesnt work

[granite owl]

it does in alot of other methods

just not here?

sec

public boolean setItemString(String key, String value)
    {
        if (this.is != null)
        {
            if (this.is.hasItemMeta())
            {
                ItemMeta meta = this.is.getItemMeta();
                meta.getPersistentDataContainer().set(new NamespacedKey(main.getPlugin(main.class), key), PersistentDataType.STRING, value);
                this.is.setItemMeta(meta);
                return true;
            }
        }
        
        return false;
    }
    
    public String getItemString(String key)
    {
        if (this.is != null)
        {
            if (this.is.hasItemMeta())
            {
                PersistentDataContainer pdc = this.is.getItemMeta().getPersistentDataContainer();
                NamespacedKey nKey = new NamespacedKey(main.getPlugin(main.class), key);
                
                if (pdc.has(nKey, PersistentDataType.STRING))
                {
                    return pdc.get(nKey, PersistentDataType.STRING);
                }
            }
        }
        
        return "";
    }

[lost matrix]

If you wrap something, make sure to add all the methods you need so you dont have garbage like this where you have to constantly unwrap the wrapped object

[granite owl]

^ code is there

[lost matrix]

if (this.is.hasItemMeta())

This might be the problem

[granite owl]

but a newly instantiated is usually has itemmeta

well

ill test it for its return value sec

boolean b = wrapper.setItemString("test", "LEMAO");
                
Bukkit.broadcastMessage(((b) ? "TRUE" : "FALSE"));

the code

[12:13:05] [Server thread/INFO]: FALSE
```well rip

how can that even happen

so my fallback condition is the issue, question stands how can an IS even NOT have itemmeta

[green prism]

How to check if a player is looking at a door?

[vale ember]

i am not sure, but looking at type ItemStack's constructor

        Preconditions.checkArgument(type != null, "Material cannot be null");
        this.type = type;
        this.amount = amount;
        if (damage != 0) {
            setDurability(damage);
        }
        if (data != null) {
            createData(data);
        }

i would assume that ItemMeta is null at the start, and when u call getitemMeta first time

        return this.meta == null ? Bukkit.getItemFactory().getItemMeta(this.type) : this.meta.clone();

it creates new via Bukkit.getItemFactory()

[granite owl]

yea ive just browsed trough the docs

seems if its null getItemMeta instantiates a new container

as such i should only check if the itemstack itself is null

as getItemMeta cant throw null errors

[vale ember]

you should probably also check if getItemMeta() is null since getItemFactory().getItemMeta() is nullable

[granite owl]

so change hasItemMeta to

[vale ember]

like this

if (is != null && is.getItemMeta() != null)

[granite owl]

is.getItemMeta != null

^^

[vale ember]

yea

[granite owl]

right ty so ive just used the implementation incorrectly xD

[vale ember]

wait, hasItemMeta() does the same thing

apparently something else is wrong

[misty current]

can you make a case insensitive query on mongo?

[granite owl]

yea ty works now

😛

[granite owl]

it does work now tho

ive changed my implementation to check for getItemMeta being null

hasItemMeta returns false

getItemMeta returns an itemmeta

[vale ember]

oh i see

[granite owl]

or at least a not null value that i can edit

properly

[vale ember]

i read it wrong, item meta checks if the this.meta is not null

[granite owl]

public boolean setItemString(String key, String value)
    {
        if (this.is != null)
        {
            if (this.is.getItemMeta() != null)
            {
                ItemMeta meta = this.is.getItemMeta();
                meta.getPersistentDataContainer().set(new NamespacedKey(main.getPlugin(main.class), key), PersistentDataType.STRING, value);
                this.is.setItemMeta(meta);
                return true;
            }
        }
        
        return false;
    }
    
    public String getItemString(String key)
    {
        if (this.is != null)
        {
            if (this.is.getItemMeta() != null)
            {
                PersistentDataContainer pdc = this.is.getItemMeta().getPersistentDataContainer();
                NamespacedKey nKey = new NamespacedKey(main.getPlugin(main.class), key);
                
                if (pdc.has(nKey, PersistentDataType.STRING))
                {
                    return pdc.get(nKey, PersistentDataType.STRING);
                }
            }
        }
        
        return "";
    }

this

[vale ember]

yeah this is correct

[granite owl]

and works now

teye

😄

but it does make sense that i didnt notice it before because the plugins main purpose is to create new custom items and add flags to it. so the item meta was never null before

[maiden briar]

I have tried things like

SELECT (SELECT *, FIND_IN_SET(rating, (SELECT GROUP_CONCAT(DISTINCT rating ORDER BY rating DESC) FROM {table} WHERE ranked = 1)) FROM {table} WHERE ranked = 1) AS r
(SELECT *, FIND_IN_SET(previous_season_rating, (SELECT GROUP_CONCAT(DISTINCT previous_season_rating ORDER BY previous_season_rating DESC) FROM {table} WHERE previous_season_ranked = 1)) FROM {table} WHERE previous_season_ranked = 1) AS previous_season_rank

But that gives an syntax error

[granite owl]

the mob spawner thing is just a minor subroutine im adding in because the framework already exists

[sacred sparrow]

umm... can i question?
What is the api in the red frame in this picture?
i search "spigot screen api",but i coudlne find it.

[chrome beacon]

Those are mods

[granite owl]

spigot has nothing to do with the frontend

[sacred sparrow]

oh really😭

[misty current]

that's blc

can you make a case insensitive query on mongo?

[chrome beacon]

https://stackoverflow.com/questions/1863399/mongodb-is-it-possible-to-make-a-case-insensitive-query

that's 12 years old and not by using the java driver

[limpid bronze]

Hey, i'm trying to send packets with sendPacketNearby but this function doesn't exist and I don't know how to access to this, i'm using protocolLib in 1.18.1

[vale ember]

maybe this could help https://www.mongodb.com/community/forums/t/case-insensitive-query-with-java-driver/1297?

[covert karma]

are you not able to use ProtocolLib?

[limpid bronze]

no i have protocolLib

[misty current]

and(eq("familyId", item.familyId), eq("userName", item.userName)) i don't really understand how this is supposed to be java code

[sacred sparrow]

thanks for your answer. i found it
https://client.badlion.net/

[covert karma]

??

[misty current]

afaik there is no such method

there's just the normal sendpacket method under PlayerConnection

[covert karma]

is the protocollib javadoc broken? it says "js is disabled in your browser" but its enabled and it says it in all browsers https://ci.dmulloy2.net/job/ProtocolLib/javadoc/

[chrome beacon]

It's not. That looks like Scala (which like Kotlin runs on the JVM)

[vale ember]

looks fine to me

[misty current]

it opens for me

[chrome beacon]

Broken for me

[limpid bronze]

oh ok

[mortal hare]

yes it is

i get the same message on my ungoogled-chromium browser

but everything works apart of search

[sand vector]

Im trying to make a pickaxe enchant which creates an explosion. This can break a hole which is the same size and can destroy obsidian. How would I do this? I have the base enchant sorted just need to make the effects

[misty current]

does the explosion have to be a sphere?

you can iterate all the blocks in an area and then check the distance between the central block and the iterated block and if it is bigger than a certain number, don't break the block

[winged anvil]

do i have to do anything extra to remove an enchant from all items in a chest?

right now im going through the chest inventory and removing mending from all items in the chest but the mending isn't actually removing

im updating the tilestate of the chest afterwards, is this why?

nevermind, it is cause the tilestate

[umbral socket]

Do I have to follow a specific file structure for my plugin to work? Does bukkit, or paper read a plugin in a specific way?

this could be helpful

[visual tide]

does anyone by any chance know what exactly is happening if the server logs are full of this
com.mojang.authlib.GameProfile@5c7f092d[id=<null>,name=lLD_Mftz*****,properties={},legacy=false] (/200.2.***.**:58251): Took too long to log in
like its a crash attempt but im not sure about how to migitate it
maybe killing the login if the id is null at some point?

[misty current]

took too long to login sounds like a network issue

i've seen often null ids so im not sure if that's a problem

[visual tide]

i dont think so

its some sort of attack

theres 40k of those invalid login attempts

and it crashed at some point

[misty current]

from different accounts?

[visual tide]

yeah

and diff ips

[misty current]

hmm

i have no idea why

[visual tide]

i dont get why it crashes, shouldnt all the login stuff be on the netty threads?

[misty current]

how long was the span of time where it happened

[visual tide]

uhm

8 minutes

and 44 thousand logins

[misty current]

sync stuff happens too, i'm not an expert of minecraft internals

[mortal hare]

ah yes

generics

[visual tide]

usernames are random strings

[mortal hare]

Collection<ServerboundPacketListener<Packet<ServerGamePacketListener>>>

[misty current]

sounds like an attack

[visual tide]

yes i figured that much

[misty current]

he he

funni

[mortal hare]

runtime casting

🙃

[tardy delta]

if the system should exit caused by a crash, should i use System.exit(0) or -1?

not in the context of a plugin anyways

[misty current]

0 is when the code ran successfully

there are different exit codes based on what happened

[tardy delta]

ah wait i meant 1 then

[misty current]

it gets much worse when you have ? extends x

i had a pretty big generic somewhere

that was pretty much unreadable

[tardy delta]

Map<Map<?, ?>, Map<?, ?>>

mapmapmap

[mortal hare]

yes positive integer numbers as error codes are the best since not all JVM implementations theoretically can support negative numbers

IN THEORY ONLY

[tardy delta]

oh lol

[misty current]

Map<Map<? extends Map<?>, ? extends Map<?>>, Map<? extends Map<?>, ?>>

[mortal hare]

We are not in dino ages

oh hey

[tardy delta]

arent we?

[mortal hare]

i just solved unchecked cast

[tardy delta]

@Supresswarnings("unchecked") smh

[mortal hare]

i managed to achieve type safety somehow

[misty current]

generics confuse me at times

i have made a /pay command that lets you steal money from others if you insert negative amounts

nice

[tardy delta]

always fun

[misty current]

[tardy delta]

/pay kill05 -100000 coins

[misty current]

/pay kill05 -10000000000000

lol

[mortal hare]

how tf

how do you store cash

[misty current]

player profiles that are then saved in a database

[earnest forum]

adding a negative is subtracting

[misty current]

yea that's what happens basically

[tardy delta]

no shit sherlock

[misty current]

it subtracts a negative amount so it sums

[misty current]

and adds a negative amount so it subtracts

[umbral socket]

Do I have to follow a specific file structure for my plugin to work? Does bukkit, or paper read a plugin in a specific way?

[tardy delta]

does this look like a good beginning??

[tardy delta]

you need to have a resources folder if you're wanting to include a config file or smth

and just put your code in your package

very simple

[umbral socket]

Ight thank you

[zealous osprey]

Quick question, atleast I hope so, is there a way to easily serialize this: {id:"minecraft:cobblestone",Count:1b,Damage:0s} into an Itemstack?

got smth 👍

[tardy delta]

i'm looking at kotlin code to get ideas for java code.. i mean...

[vale ember]

is it json?

[tardy delta]

json would be "Count": true

[zealous osprey]

Thing is... it's kinda mojankjson, since it doesnt work correctly

[zealous osprey]

^^

[chrome beacon]

If it's Mojangson use the TagParser class

(NMS Mojmaps)

[tardy delta]

it prints 18 how do i make it print 19?

looks like the right bound of #between is exclusive

[chrome beacon]

So you want it to round up?

[tardy delta]

it would make sense to print 19 seconds if the cooldown was 20s and only one second passed no?

[chrome beacon]

I would assume something took slightly longer and it's like 18.99 seconds

[tardy delta]

actually, lets print the millis

18995

i guess thats why

just adding 15 milliseconds now smh 😂

[ebon topaz]

how do i make a config file

[chrome beacon]

https://www.spigotmc.org/wiki/config-files/

[humble tulip]

A custom one?

[tardy delta]

just follow the guide

[ebon topaz]

The embedded resource 'config.yml' cannot be found in plugins\resourcepacker-1.0-SNAPSHOT.jar

[humble tulip]

You need to put the config in your jar file

Are ypu usijg maven?

[ebon topaz]

mhm

[humble tulip]

You using*

Do you have a config.yml in your resoirces folder?

[ebon topaz]

ah

[tardy delta]

saveDefaultConfig() in your onEnable

[balmy fox]

When using this player.getInventory().getItemInMainHand().getType().name() to get name of item in MainHand it returns the right names whit most of the block. But by the new blocks and items like Amethyst Shard it returns AIR. How can I fix that?

[chrome beacon]

Send the output from /version

That sounds odd

[balmy fox]

Of my server?

[chrome beacon]

Yes

[brittle lily]

Thats weird

[balmy fox]

Maybe not the right versions of the plugin?

[chrome beacon]

Ask Paper I guess

[chrome beacon]

Show code

[balmy fox]

Fair, but just wanted to be sure that I wasnt doing weird things with the code

[brittle lily]

I'm codin 1.12 What version should be vault?

[chrome beacon]

Latest

Vault doesn't really care about mc version

[brittle lily]

?paste

[undone axle]

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

[brittle lily]

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

[chrome beacon]

Did you add Vault as depend in your plugin.yml

(Or soft-depend)

[brittle lily]

oh Actually I didnt add on plugin.yml

[grim ice]

yeah

make a JsonItem class with the fields id count and damage

then use gson to turn the json into the class

then have it implement ItemForm interface which has a static method

ItemStack toItem(ItemForm itemForm)

[chrome beacon]

It's mojangson not json

[grim ice]

that sets the fields from json to an item stack

[chrome beacon]

There is a difference

[grim ice]

idk whats mojangson

[brittle lily]

I depend on my pom.xml its enough?

[grim ice]

but im doing what i would do in a normal java project i assume

dunno about these mojang quirks

[chrome beacon]

No. soft-depend in the plugin.yml

[brittle lily]

I didnt how can I

[chrome beacon]

Json but a little more accepting

[humble tulip]

softdepend: [Vault]

[brittle lily]

Guys I solved it was about economy plugin when I download EssentialsX its worked

[humble tulip]

You also need softdepend: [Vault]

So ur plugin always enables before vault

[heavy marsh]

Anyone know why sometimes I get a "CraftBlockState cannot be cast to Container" here:

Block block = ((Location)serializedMap.get("container")).getBlock();
Container container = (Container)block.getState();

[tender shard]

because it's not a container

[humble tulip]

Check if it is first

[heavy marsh]

this is in a deserialize method, what would I do if it isn't a container? Can I return null in that method?

[humble tulip]

Mqke sure you specify the api-version in plugin.yml

[humble tulip]

I'd assume so

[tender shard]

what do you need the container for anyway? in the code you sent, you only cast it to container and then not do anything with it

[humble tulip]

It depends on what you want to happen if it's not a container

[heavy marsh]

sorry, here is the whole method for context:

public static LockedContainer deserialize(Map<String, Object> serializedMap) {
    String ownerUUID = (String)serializedMap.get("owner");
    OfflinePlayer owner = Bukkit.getOfflinePlayer(UUID.fromString(ownerUUID));

    Block block = ((Location)serializedMap.get("container")).getBlock();
    Container container = (Container)block.getState();
    UUID uuid = UUID.fromString((String)serializedMap.get("uuid"));

    LockedContainer deserialized = new LockedContainer(container, owner, uuid);
    return deserialized;
}

[tender shard]

well you have to know for yourself whether you're fine with this returning null or not

[heavy marsh]

it is YamlConfiguration.loadConfiguration which runs all the deserialize methods, I just don't know if would be happy with null being returned. I can test it ig

[humble tulip]

It is

[heavy marsh]

ok cool

[reef lagoon]

Can I make a player say a message with a tooltip?

[waxen plinth]

Using chat components

[heavy marsh]

Hmm (sorry for ping)

[humble tulip]

Hm

A lockedcontainer is a chest?

[heavy marsh]

Surely there must be a way to abort a deserialization or something?

[twilit roost]

stupid question
but how does Method#invoke work?
since I have shoot()
and Im getting the method and just doing method.invoke(null)
But it returns null

[heavy marsh]

Chest or barrel

[humble tulip]

Is shoot static and void?

[ivory sleet]

it’s first argument is the instance

[humble tulip]

Well maybe you just wanna store the location in lockedcontainer

[ivory sleet]

Or null in case the method is static

[twilit roost]

its void
and its Overriding from SuperClass

[twilit roost]

therefore class?

[ivory sleet]

so like

lol.doStuff();

would be getMethod("doStuff").invoke(lol)

[humble tulip]

Oh well you need to pass what you're invoking the method on

So if u wanna invoke it on a player, you do method.invoke(player)

Which is the same as player.shoot()

[twilit roost]

ooh right

i thought it was enough when I got the class,method

[ivory sleet]

It’s only if the method is static that you pass null to invoke like .invoke(null)

Same goes for Field::get

[twilit roost]

Caused by: java.lang.IllegalArgumentException: object is not an instance of declaring class

[ivory sleet]

You passed an instance of wrong type

    }

[river oracle]

Wait are you using reflection internally of your own plugin

[twilit roost]

yep 😄

[river oracle]

Why...

Did you not properly expose classes need so your compensating via reflection

[ivory sleet]

its just gonna make ur code more complicated and slower 🤨

[humble tulip]

Why don't u just cast to rangedweapon and call shoot normally?

[twilit roost]

I have Super class RangedWeapon and my Weapons are extending it

Yet I have no other idea how to execute method when the class is extending RangedWeapon

[river oracle]

Using reflection in your own code makes almost 0% sense a good 90% of the time

[humble tulip]

If obj instanceof RangedWeapon

[humble tulip]

Yeah cuz ur providing a class

[twilit roost]

forgot to cast

[humble tulip]

U can't cast thwt

[river oracle]

Bro what are you on

[twilit roost]

sleep deprecation

[river oracle]

This is a simple instance of call no classes needed

[humble tulip]

Just regoster each rangedweapon with an instance

Register*

Have a manager class for weapon so u can call weaponManager.register(Weapon)

That class can also give you the weapon for a given itemstack

Bump

Conclure can you maybe have a look? ^^

Interface

[river oracle]

I said thag already

[glossy venture]

Hello !
I've created a fly command, and I'm trying to remove fall damages only after the command /fly (when fly is disabled)...
How can I do this ?
I tried 3 things:

• Create a list, then put the player in this list when he does /fly. When he get fall damages, cancel and remove the player from the list.
  Problem: The player is still in the list if he wasn't falling, and he will be safe for his next fall.
• Remove the player from the list when he hits the ground
  Problem: He hits the ground before getting damages, so he will get damages
• Use the method Player#setFallDistance() after using the command, but it doesn't work (idk why).

[agile anvil]

What fall distance did you input ?

[rotund pond]

0.0F

Like Essentials :']

[tardy delta]

just look at their source code on github 😉

[rotund pond]

I tried with -10.0F and not working
Same with -5000.0F and not working :']

[rotund pond]

Gonna take a look

[rotund pond]

Well, that's the same thing :']

[tardy delta]

the decompiled code shows weird stuff sometimes

[reef lagoon]

event.getPlayer().chat(message); what's the problem with this

[chrome beacon]

You're doing it async

Do it sync

[reef lagoon]

nvm

[ivory sleet]

^ its gonna go off thread anyway

[dim palm]

create a BukkitScheduler with runTaskLater(), once the player hits the ground you remove it from the list

[rotund pond]

Gonna try

[tardy delta]

removing fly damage when fly is disabled? wait wha..

or am i reading ir wrongly

[brittle lily]

Guys I have a custom ItemStack. I wanna make event with When ItemStack Placed on the ground but I cant cast my custom Item to Block How Can I Do That

[rotund pond]

falling damage

[tardy delta]

uh ye

[rotund pond]

What's wrong ?

[tardy delta]

im not understanding this
I've created a fly command, and I'm trying to remove fall damages only after the command /fly (when fly is disabled)...

[stiff zinc]

Hey, I have a weird error happening today with Maven and I can't seem to find any fix for it.
Basically, I'm building an API for changing player skins. I've already done this API in the past, but I'm currently rewriting it.

This is the project structure:
The API contains the PacketProvider<T> class for sending the correct packets for the given Bukkit version: https://github.com/itspinger/DisguiseAPI/blob/master/API/src/main/java/net/pinger/disguise/packet/PacketProvider.java

Each module has a class which implements the PacketProvider<Packet> class (1.16.4 for example):
https://github.com/itspinger/DisguiseAPI/blob/master/v1.16.4/src/main/java/net/pinger/disguise/packet/v1_16_4/PacketProviderImpl.java

The plugin module is the module where all modules are combined within the PacketContext implementation
https://github.com/itspinger/DisguiseAPI/blob/master/Plugin/src/main/java/net/pinger/disguise/packet/PacketContextImpl.java

But what happens when I actually try to compile is I get the cannot access net.minecraft.server.v1_14_R1.Packet error when I do a mvn clean install

[rotund pond]

wow

[tardy delta]

remove embeds pls

[stiff zinc]

wtf

[rotund pond]

Well, you do /fly, you can fly you're happy
Then you do /fly while flying and you're falling. I want this fall to deal no damage, and only this one

[ivory sleet]

<link> will remove embeds fyi itspinger

[stiff zinc]

okay

[tardy delta]

something in my head is saying that whenever you fall when just having set Player#setFlying to false, that you dont get fall damage but that cant be true

[rotund pond]

Ah, gonna try and tell you

[earnest forum]

theyre trying to cancel fall damage for only the fall that happens after fly is turned off

[tardy delta]

i understand ye

[unreal quartz]

Have you actually ran buildtools for all those versions

[tardy delta]

or just set the fall distance?

[stiff zinc]

No I don't use buildtools

But they build fine in own modules respectively

Like only the Plugin module fails with that message

[chrome beacon]

But you need to run BuildTools to have the nms dependency 🙃

[stiff zinc]

1.8.8, 1.9.4 build fine

[rotund pond]

Not working ^^'

[stiff zinc]

I'm using a repository 😄

[chrome beacon]

Oh no

[tardy delta]

what parameter did yu give it?

[stiff zinc]

It's already built on my machine either way

[unreal quartz]

Well the plugin module lists all those versions up to 14 as a dependency

[rotund pond]

  @Override
  public void disableFly(FileConfiguration fileConfiguration, boolean forced) {
    Player player = this.getPlayer();

    if (player == null) return;
    if (!player.getAllowFlight()) return;

    player.setFallDistance(-500f);
    player.setFlying(false);
    player.setAllowFlight(false);

    String flyDisabled;
    if (forced) flyDisabled = fileConfiguration.getString(Message.FLY_DISABLED.getKey());
    else flyDisabled = fileConfiguration.getString(Message.FLY_OFF.getKey());
    player.sendMessage(MessageUtils.setColorsMessage(flyDisabled));
  }

[tardy delta]

-500?

why not just 0 or 1

[stiff zinc]

Yeah

[chrome beacon]

Depending on an illegal distribution of Mojang code is not good

[rotund pond]

Because someone asked me to put a negative value
Gonna try with 0

[stiff zinc]

The 14 fails

And when I remove the 1.14 the 1.13 fails

[tardy delta]

maybe put setfalldistance after you disable its flight

[unreal quartz]

Yeah, so you don't have the nms dependency available in your build path

Either whatever repo you're using doesn't serve it, or you don't have any of them locally

[rotund pond]

both are not working (0 as a value and put setfalldistance after disable its flight)

[stiff zinc]

https://gyazo.com/5abff18deb822c315627e0acfeca4141

They are all in my .m2

[rotund pond]

Found !
I've put a huge negative value in setFallDistance and it's working xd

[stiff zinc]

https://gyazo.com/20b15ffa0b5e46e077a263f4dc55d55a

[tardy delta]

lol

[stiff zinc]

IDE points me to the line where I add them to the providers set

Like I said, the Plugin module is the one that fails building, the other modules build just fine

    public PacketContextImpl() {
        // Add default providers here
        // this.registeredProviders.add(PacketProviderImpl.class);
    }

If I comment out the line and then try to build, it builds fine

So Idk why that happens

[unreal quartz]

Haven't work with maven for a while, but maybe it's because the specific versions have the nms dependency with the provided scope? Maybe that's why the plugin module doesn't have the nms dependencies as transitive dependencies

[atomic niche]

Without NMS or mixins, is there any reliable direct way to cleanly redirect an end exit portal to a specific destination in the overworld?
We have an indirect workaround, but its 100+ lines, requires a bunch of vector calculations, and is a slight pain to maintain.

[stiff zinc]

No that shouldn't be the problem

Provided means that the compiler shouldn't inject it into the jar

It should already be loaded within the JVM

I've tried googling but it doesn't get me anywhere

If I did use <compile> tag on all of them the .jar file would be huge aswell

More than 70mb probably

[unreal quartz]

Only if you shade it

You can try with the compile tag and see if it works

But looking at the documentation, it says that provided dependencies aren't offered as transitive ones

[stiff zinc]

Yeah but that shouldn't stop it from compiling

I'm not actually using any of the nms classes inside the Plugin module

[kind hatch]

The <provided> tag should be what they need though.

[stiff zinc]

I'm using wrapper classes

[unreal quartz]

Do you mean the PacketProviderImpl classes? Because they import net.minecraft

[rotund pond]

I don't get the difference between Location#getY and Location#getBlockY 🤔
IntelliJ says they can be null, but why ?
(Using it in EntityDamageEvent, to prevent fall damages)

[lavish folio]

can i get radius from one location to new location?

[rotund pond]

Radius ? Do you mean distance ?

[lavish folio]

yes sorry

[kind hatch]

EndGateway#setExitLocation()

[rotund pond]

something like Location#distance

[atomic niche]

That only works for end gateways; not end portals.

[lavish folio]

thanks

[kind hatch]

Location#getY() returns the exact Y value. (52.57182)
Location#getBlockY() returns the floored (rounded down) Y value. (52)

[mighty pier]

how to get the thing where you fall over and turn red and shit the carpet?

[rotund pond]

There's no more difference so ?

[mighty pier]

in spigot

[rotund pond]

??

[mighty pier]

you die

and you turn red and fall

the animation thing

[kind hatch]

I mean, that's the difference. Depending on what you need, one returns an int, the other returns a double. So, use that as you need.

[rotund pond]

Ah, idk sry

[rotund pond]

Alright thank you 🙂

[stiff zinc]

Yes they import them but I'm not instantiating them anywhere

I'm using .class only to store the classes

Like I'm not directly importing the net.minecraft inside the Plugin module

[kind hatch]

Then why not remove the dependency in the pom then?

If it's not used anywhere in the actual module, then it can be removed.

[stiff zinc]

Well it's not included in the Plugin module

But it is in the version modules

Because I need it there

Could anyone clone the repo and try to build it

Incase it's only on my machine lol

[atomic niche]

Btw, what was the rationale for making end portals so aggressive?
How long do PRs take with spigot? Would an end portal fix be within the purview of what one might be able to get merged?

The fact that it takes a load of vector calculations to redirect an end portal seems like an api limitation worth addressing

[unreal quartz]

Can't find whatever net.pinger.disguise:PacketHandler is

[stiff zinc]

Wait let me push the latest

[stiff zinc]

Okay done

[zealous osprey]

How would one check if a block is a tileentity?

[eternal night]

check if its state is a TileState

[zealous osprey]

Will do, thx

[kind hatch]

I mean, you could just cancel the PortalEnterEvent, check the block location, then teleport the player to the new location based on the portal block they entered.

[atomic niche]

EntityPortalEnterEvent can not be cancelled

[kind hatch]

What about the EntityPortalEvent?

[atomic niche]

Not called

[heavy marsh]

Hello I have a listener for the BlockBreakEvent and I cancel the event when the player tries to break a specific block, but the block still breaks anyway, anyone know why?

@EventHandler
public void onBlockBreak(BlockBreakEvent event) {
    Block block = event.getBlock();
    if (!manager.isLockedContainer(block)) return;
    event.setCancelled(true);
    logger.info("cancelled");
    ...
}

(the log message is sent)

[atomic niche]

PlayerRespawnEvent is what gets called, and it also can not be cancelled

[kind hatch]

Weird, because that should get called.

Called when a non-player entity is about to teleport because it is in contact with a portal

Oh

wait

lmao

[atomic niche]

End exit portals are a special case

there is no cancellable event that gets called, and thus, if the player touches the block, it is impossible to cancel the teleportation.

[kind hatch]

Sorry, what about the PlayerPortalEvent?

[unreal quartz]

Got the same error as you, it seems like .class ends up initialising the class? Because when I remove the scope for the 1.16 module it compiles successfully

[stiff zinc]

Yeah it does compile but the whole jar gets shaded inside

[atomic niche]

neither called nor applicable for entities.

[stiff zinc]

And I don't really want that

But it makes no sense why that would happen aswell

Like

I've never had this problem

[kind hatch]

Hmm, what are you wanting to happen then? Cause there are workarounds that don't involve using vector math. It can be as simple as block detection and teleportation. It just depends on what you want specifically.

[atomic niche]

nope

PlayerRespawnEvent and EntityPortalEnterEvent trigger before PlayerMoveEvent

You need to catch the blocks surrounding the portal and make them the teleport triggers, which makes it seem unnatural

Our workaround involves using a bunch of normalised vectors to predict the motion of the player or entity.
Using those checks, we determine whether it is likely they will hit a portal.

We then use some more expansive checks to expand the portal block's hitbox by 0.1 blocks, and teleport the player before they can touch it.
If the player is going too fast, we let them touch it, then hijack the respawn event to force them to respawn at a specific location in the overworld.

[kind hatch]

I'm telling you, there are other/better workarounds.
Have you tried PlayerTeleportEvent#setTo()

[atomic niche]

Doesn't work for entities, doesn't get called in the first place

End exit portals do not technically teleport the player; they force the player to respawn

not only do they force the player to respawn, they do so the moment the player touches a portal, and before the player technically moves there with PlayerMoveEvent

[unreal quartz]

So I can't quite explain why, but it seems like removing extends PacketProvider<?> from line 14 (so that it's just private final Set<Class<?>> registeredProviders = new HashSet<>();) allows it to compile?

[atomic niche]

The only way around that is to cancel the respawn event (or the EntityPortalEnterEvent) with nms.
Or, to implement your own detection algorithm slightly out from the block.

Such algorithms are flawed though at maximum velocities though, so hijacking the portal event is required

[kind hatch]

Can you explain what you are trying to achieve? From what I gather, you are making a teleportation system that uses end portals that works for all entities.

[zealous osprey]

Welp, I should have been more precise... I'm in 1.12.2, TileState doesn't exist yet.

[eternal night]

what

[zealous osprey]

I cannot check for TileState

[eternal night]

Well, rip

[atomic niche]

Basically, we have a recursive teleporter able to teleport literally any combination of players and/or entities.
This can be triggered by any "traversable" block set by the player; one such block is an end portal.

Thus, we want to be able to teleport any combination of players and/or entities that hit an end portal.

This is our current workaround; it feels a bit much for what should be a simple task.
https://github.com/stargate-rewritten/Stargate-Bukkit/blob/4fa09c15c20cdebf6dd9e26a56a690be07ff8f75/src/main/java/net/TheDgtl/Stargate/listener/MoveEventListener.java#L92-L202
Basically trying to determine if there is an existing direct solution, or if this is a PR-worthy issue.

The easiest solution would just be if PlayerRespawnEvent or EntityPortalEnterEvent had setCancellable

[heavy marsh]

help please

[atomic niche]

Hence the prospect of a PR

[kind hatch]

I don't think those would be accepted though. Player respawning is important for many things. Being able to cancel that event in a plugin could cause the game to break. However, I think this is one of those cases where you would have to listen to multiple events if you wanted this to work as expected. Due to the Teleporation logic for players and entites being split into their respective events. (PlayerTeleportEvent & EntityTeleportEvent)

Players have the TeleportCause enum that you could leverage, but regular entities don't. (Entity teleportation is pretty easy though.)

[atomic niche]

The problem here though is that it isn't teleportation

When you enter an end exit portal, you do not teleport

therefore, none of the teleportation events get triggered

[limpid bronze]

Hey, I'm trying to follow this https://www.spigotmc.org/threads/1-8-1-13-custom-block-breaking-change-block-hardness.362586/ for a custom block breaking system but this tutorial is outdated (i'm in 1.18.2), I still have follow this tutorial and the system doesn't work properly. Is there a updated tutorial or someone that can help me about that? The principal problems are:

• PlayerAnimationEvent is not called sometimes when it should
• The author of this tutorial forgot to calculate time that should take to broke the block depending on the tool used
• The author of this tutorial forgot to set hardness depending on the block

[atomic niche]

Neither PlayerTeleportEvent nor EntityTeleportEvent is called.
The actual "Teleportation" is playerRespawnEvent

[kind hatch]

That's odd. I wonder if the other events get fired later or are tied to other specific use cases. Because they wouldn't exist otherwise.

Let me setup a test server and try some of this stuff out.

[smoky oak]

cant you just set the goal of playerrespawnevent to where the player currently is instead of cancelling it

[atomic niche]

PlayerMoveEvent is called after EntityPortalEnterEvent, which itself results in PlayerRespawnEvent.
By allowing EntityPortalEnterEvent to be cancelled, it would fix this whole mess.

As for those other events, the TeleportEvents and PortalEvents occur for all other portals, and thus, exist.
Its just end exit portals that are a special case.

[atomic niche]

The problem is, it will still result in an uncancellable teleportation to the overworld.
We can hijack where they end up in the overworld, but we can not control their order.

This makes reconstructing complex entities difficult

Also makes it less than seamless if the destination is in a dimension other than the overworld.

For example, try to teleport an experience bottle riding a bat leashed to a boat riding a furnace minecart riding a donkey riding a player to the nether from an end exit portal.
It can be done by hijacking various respawn events and reconstructing everything.

It's just far more complicated than doing it directly, and is very noticeable for the player.
The easier solution is just to prevent the respawn events and do it yourself.
That involves a load of vectors and whatnot, with respawn hijacking as a fallback for high velocity entities.

[smoky oak]

why not save all passengers into someting, teleport the player, then set the passengers of the player back to whatever that stack was

[kind hatch]

Ok, just did some testing and the PlayerPortalEvent & EntityPortalEvent are both cancellable.
When I try to enter a normal end portal. The event is cancelled.
When I place a mob in the portal, the event is also cancelled.

[smoky oak]

iirc theres some special rules for passengers and teleports

[heavy marsh]

please can someone take a look at this and explain what is going wrong

[kind hatch]

You return before you cancel the event. Instead of returning just cancel the event if the block is locked.

[stiff zinc]

It does in fact solve the issue

But I'm wondering whether I should leave it at that

[heavy marsh]

hmm? that is intended, it should only cancel if it is a locked container

[stiff zinc]

Even doing Class<? extends PacketProvider> works

But I get the raw use of parameter type warning

[kind hatch]

Yes, but you use the return keyword before you set the event as cancelled.
return stops code execution.

[smoky oak]

its part of the if claus

[atomic niche]

Because we can't stop everything from being teleported to the overworld, and can't control the order of the teleportation.
If they are going to the nether, this becomes very messy; it also becomes very noticeable to players, and thus, clunky.

[smoky oak]

ha?

i thought passengers are unaffected by nether portals?

[heavy marsh]

yes, but that return is only ran if the block ISNT a locked container

plus I have already confirmed the code gets past that point

the problem is that even though the event is being cancelled the block still breaks

[kind hatch]

Then your check isn't doing what it needs to.

If it's getting past a guard clause, then you need to reevaluate what you are checking for.

[heavy marsh]

🤨

[kind hatch]

Think about it.

[smoky oak]

@kind hatch he is saying the block breaks even if he sets the event to cancelled, also, im fairly certain that check does what it's supposed to

[kind hatch]

I'm not sure it does. Otherwise the event would be cancelled.

Unless you have another plugin on the server that is interfering with yours, then it comes down to that one check.

[kind hatch]

Did you see my testing with the events?

[atomic niche]

Sorry, three conversations at once.
Missed that; one min

[atomic niche]

Just making sure, this is an end exit portal?

[kind hatch]

No, that is a normal end portal.

[atomic niche]

i.e. a portal in the end going to the overworld?

Radically different

Portals in the overworld going to the end are easy enough to deal with

[kind hatch]

Either way, it gets called for every portal I make and try to use.

[atomic niche]

Have you tried going from the end to the overworld?

[kind hatch]

Let me see.

[atomic niche]

That's going to the end though

what about going from the end to the overworld?

i.e. exiting the end

[atomic niche]

Nether portals != end exit portal.
End portal != end exit portal.
End gateway != end exit portal.

[smoky oak]

whats the difference between PlayerInteractAtEntityEvent and PlayerInteractEntityEvent?

[kind hatch]

@atomic niche

[atomic niche]

End gateway != end portal?

[kind hatch]

Yes

They are separate things.

[atomic niche]

Why is end gateway firing if its an end portal?

[kind hatch]

It's not.

I entered The End. Killed the dragon, then entered an End Gateway

[atomic niche]

end gateways are these things

nvm, cant upload screenshots

either way, not something I care about

end exit portals are the things that spawn when you kill the dragon

[kind hatch]

End Gateway

[atomic niche]

^ Don't care about those

[kind hatch]

You mean this?

[atomic niche]

yes

[kind hatch]

Oh, well yea.

That fires the Respawn event.

That's the end of the game.

[atomic niche]

indeed

I want to redirect one of those

And that's why I need a 100+ line vector workaround

[kind hatch]

Ok, that helps clear things up. Let me see if I can't find anything about it.

[atomic niche]

As far as I am concerned, there are six solutions

[kind hatch]

Ok, already have an idea.

The end has a special property.

Every end portal in The End acts as the end dragon portal.

[atomic niche]

1. Crazy vector workaround (we are doing this) with respawn hijackcing as a fallback for high velocity entities.
2. Brick the end exit portal with NMS.
3. Brick the end exit portal by screwing with world loading.
4. Replace the end exit portal with falling end portal blocks.
5. Get a PR to make EntityPortalEnterEvent cancellable
6. force a bunch of bounding boxes and detect colisions

[atomic niche]

Correct; this solution needs to apply for specific end exit portals, i.e. any arbitrary portal placed in the end.

    private void dropItem(Location location, int amount) {
        for (int temp = amount; temp > 0; temp--) {

            item.setVelocity(new Vector(0, 0, 0));
        }
    }

Can someone explain briefly what this code does

[compact haven]

dropItem

[flat galleon]

with little more detail than that ;-;

[heavy marsh]

@kind hatch I have removed all other plugins, the problem still happens, though may I point out it is only handled incorrectly if the person breaking the block is not the owner of the locked container (as far as I can tell)
Here is the repo, maybe you can take a further look with more context https://github.com/Synthetic-Dev/LockedContainers/blob/main/src/main/java/me/syntheticdev/lockedcontainers/events/BlockListener.java#L47

[smoky oak]

from what i can tell if you drop an item it drops every item of it separately and possibly renames them depending on if a flag is set

[tender shard]

why not use the dropItem method that takes a consumer?

[compact haven]

It spawns a number of “ore”s at the provided location in the provided amount and adds a special metadata to prevent stacking, if it’s not meant to stack

[smoky oak]

oh hey alex... do you know if i can override nms without having to rebuild the server?

[limpid bronze]

Can someone help me?

[eternal night]

beyond mixins not much

[smoky oak]

u mean me?

[tender shard]

wdym with override?

[smoky oak]

i want to change the inner workings of the server to use my method instead of the provided one

it was something in LivingEntity

dont know the exact name atm

[flat galleon]

This is a piece of code from an open source plugin that someone was calling out bad. I don't understand it myself. But, I was just looking for what would be a good code xD

I hope to understand this as I get more proficient with spigot development

[heavy marsh]

(Or anyone else who can help, you'll have to scroll up to understand the conversation though)

[chrome beacon]

As Lynx said you can load Mixins and make changes. However that might not be ideal if you plan on releasing it as a public plugin

[smoky oak]

ah that was it. I wanted to override LivingEntity#isDamageSourceBlocked

[limber owl]

how do I get players respawn location?

[heavy marsh]

player.getBedSpawnLocation

[limber owl]

if that's null?

[tender shard]

when do you need the respawn location?

[heavy marsh]

Then they will spawn at a random location near world spawn

[limber owl]

I'm teleporting player so it can't be null

[smoky oak]

to be precise i want to skip line 1434

[limber owl]

for safety reasons

[smoky oak]

why not?

[chrome beacon]

Because you would need to make a custom jar that launches instead of the server jar

[heavy marsh]

There isn't really much you can do apart from not teleport them since they don't have a respawn location

[chrome beacon]

Your jar then needs to launch the server

Basically you need the Mixins to load quite early

[smoky oak]

im not good enough for that urgh

is there any other possebility?

[kind hatch]

@atomic niche I guess I'm getting different results.

[atomic niche]

Is that going from the end to the overworld?

[kind hatch]

Yes

It also looks like the EntityPortalEnterEvent gets called first according to the output.

[atomic niche]

Yes, but EntityPortalEnterEvent can not be cancelled

[kind hatch]

But it can be leveraged.

You could use it to store information about a player or entity. Then in whatever event you want to use, use that information you stored to make comparisions.

[atomic niche]

but how does one go about preventing the applicable respawn events?

PlayerMoveEvent's getTo is too late
Neither EntityPortalEnterEvent nor PlayerRespawnEvent can be cancelled

We have all the information we need for the teleport;
The missing information is when to preform the teleport.
To make it as seamless as possible, we want to teleport the player a fraction of a second before they would trigger the respawn events

[kind hatch]

I think you would actually want to use the RespawnEvent and just set the respawn location using PlayerRespawnEvent#setRespawnLocation()

That way it is seamless.

[chrome beacon]

Probably not

[kind hatch]

How so?

[atomic niche]

The thing is,
a: that forces overworld.
b: it's a pain to resync entities when hijacking the respawn

[kind hatch]

If they check for the proper criteria, it should be fine.

[chrome beacon]

Actually nvm

It might be fine

[kind hatch]

How does it force overworld? That method takes a Location object. In which you can set the world.

[atomic niche]

ah

nvm, I guess I misremembered something

Anyways, still a pain to resync. For example, several parts of the entity recursion can enter the portal at the same time.
When rebuilding the entity, it needs to be done in a very specific order with very finicky timings, or stuff breaks.

If you have an experience bottle riding a bat leashed to a boat riding a furnace minecart riding a donkey riding a player.
And if the teleportation is not handled with very specific timings, everything will fall apart.
It can be rebuilt, but it gets really confusing and messy

Handling the teleport ourselves, unless absolutely necessary, makes life easier

[kind hatch]

Why do you need to rebuild the entity? Just use the methods from the events.
EntityPortalEvent#setTo()

Or, Entity#teleport()

[atomic niche]

Because none of the existing spigot teleport events are able to deal with complex entity stacks

they invariably split apart after one or two deep recursion

and they fail to handle leads

[kind hatch]

Wdym entity stacks?

[smoky oak]

again why not stuff all passengers except the main entity into something and the restore it once the main entity teleported

unless a player is a passenger

you should be fine

[atomic niche]

Because of how MC handles remounting and entity presence.
It's very finicky and requires precise timings.

Reassembling something is a pain, especially with circular components

[heavy marsh]

I don't think even vanilla supports stacked entities going through portals?

[smoky oak]

how the fuck do you stack entities in a loop

[kind hatch]

You mean passengers? No

[atomic niche]

Passengers are not complex entities

[kind hatch]

It supports players riding entities, but that's it.

[sterile token]

Why isnt possible to know the slot on InventoryDragEvent

It had broken my menu api

😡

[kind hatch]

Because you are dragging an item. You could be dragging multiple items across multiple slots.

[sterile token]

Okay

So how can i cancel it?

[atomic niche]

.
1️⃣
⬆️⬇️
2️⃣⬅️3️⃣

This is circular leashing ^

[sterile token]

Because i keep items as Map<Integer, MenuButton>

[smoky oak]

why not just cancel inventorydragevent if its in your menu

[sterile token]

Oh yeah good idea

Just cancel it

Instead of checking the button

[smoky oak]

check if it does something weird to items but you shouold be fine otherwise

[sterile token]

Thanks matter

[kind hatch]

Well, you will probably still have to do some things when it comes to entity teleportation, but simplifying the teleportation logic is the first step.

[heavy marsh]

Shadow are you able to take a look at my problem again?
Here is repo and line: https://github.com/Synthetic-Dev/LockedContainers/blob/main/src/main/java/me/syntheticdev/lockedcontainers/events/BlockListener.java#L47

Dont ask someone for specific help!

[heavy marsh]

We were already having a convo but I can send the problem again

[naive bolt]

can i have multiple items in a ItemStack

[smoky oak]

no

but you can have the same items a lot of times in it

ie

a stack

[naive bolt]

yea

[smoky oak]

long story short

[naive bolt]

but for different items needs a new item stack

[smoky oak]

itemStack = 1 slot

[sterile token]

yeah

[smoky oak]

and a shulker is a single item just with some extra data that is its contents

[sterile token]

Yeah because a banana is no the same as an apple. They are 2 fruits but are totally diff

😂

[kind hatch]

Reading this is a little confusing due to how you name your methods.
Also, your double chest logic in the #isLockedContainer() method might be causing some issues.

[heavy marsh]

What is wrong with that logic? I've tested it and it seems to work

[sterile token]

Yeah his methods name are really extrange

[kind hatch]

You have three methods for checking the same criteria. Named slightly differently or overloaded. Then in your #isLockedContainer() method you have a boolean called is It would help if it was named isLocked That coupled with the boolean using different checks makes this a little more confusing.

Anyways, that method first checks it see if the container is a proper type of container. You then use a different named method to get the same result. Which is then used to check for double chests.

I'm not sure if it is causing your issue, but it is definitely not easy to read.

[acoustic pendant]

hey! does someone have any tutorial about using mounts? such as mounting ender pearls, i haven't found anything in google. Thanks 😄

[kind hatch]

https://www.spigotmc.org/resources/rideableenderpearl.72042/ This plugin has a GitHub page for it.

[acoustic pendant]

okay, thanks!

[naive bolt]

whats the best way to turn a string from config into a itemstack

[kind hatch]

Material#valueOf()

[naive bolt]

what about an array so

NETHERITE_INGOT,
ENCHANTED_GOLDEN_APPLE
]```
and drop both them items

[kind hatch]

Iterate over your list.

[smoky oak]

is a string hard coded noticeably less efficient than having a separate text file containing the string if its around 1-2k words?

[kind hatch]

Not really. Strings are already the worst thing in terms of memory, but if you are grabbing it from a file, it would be the same as hard coding.
The only real difference would be the overhead for the file object. Once that gets gc'ed you are left with the same string.

[smoky oak]

ah well i was just wondering if pasting strings or eventually json is better done as hardcoded string or as file in src/resources

long strings i mean

i dont make an extra file for a regex string

[kind hatch]

I mean, if it's a file that's part of your plugin, you will have that file overhead unless you are streaming it.

[smoky oak]

i would be streaming it to read it in i think

[atomic niche]

Entity#addPassenger is very finicky for complex entities and requires very specific timings to avoid breaking apart.
Preventing leashes from breaking is also very difficult and requires carefully managing all stages of the teleportation.
Restoring momentum and dealing with legacy entities is also a challenge that requires careful execution.

Ensuring the above occurs seamlessly without desync or other visual problems is a challenge.
It involves a carefully considered DFS algorithm, a load of timing and motion calculations, etc.
It would be extraordinarily difficult to get that algorithm to work within the constrains of respawn events.

We originally tried simply hijacking respawns, but for particularly complex entities, it causes visual problems.
It works, but not in a way that is seamless for players; as such, its our fall-back method and not our solution.
By handling teleportation ourselves without respawn events, we can offer a much better player experience.

Anyways, thank you for help 🙂

[smoky oak]

i dont exactly recall how i normally do it

[umbral socket]

getting multiple errors after setting a folder as package

[smoky oak]

something something getResource iirc

i think that was a stream

[compact cape]

How can you register an event to just call a method?
It's not going to be always the same Classes so I can not use Event Handler annotation

private void update() {
    // Some stuff
}

public void updateWith(Class<? extends Event> event) {
    // Call update when the event triggers
}

// on enable
public void onEnable() {
    // An example
    MyClass.updateWith(PlayerDeathEvent.class)
    MyClass.updateWith(PlayerLeaveEvent.class)
}

[heavy marsh]

I don't find it too hard to read, also, there is no method that gives the same result?

[smoky oak]

actually you can. Its possible to register other classes to the plugin as event handlers

[compact cape]

JavaPlugin#getResource ??

[smoky oak]

grabs a file with the path having its origin in the same folder your plugin.yml is

[river oracle]

you should always use the event handler annotation and you should always implement Listener.

[compact cape]

I can't create event handler for all the possible events that might be passed to the plugin

[smoky oak]

actually you can

[river oracle]

you know you can create multiple events right

[compact cape]

I just want to trigger the update...

[umbral socket]

getting multiple errors after setting a folder as package any help?

[kind hatch]

Well, do you know which part is giving you issue? What are you expecting to happen and what is actually happening?

[naive bolt]

whats a way to do a 50/50 chance

[river oracle]

what is "the update"

[compact cape]

It must be the folder the class is in

[smoky oak]

random.double > .5

[naive bolt]

like random number between 0 1 and if its 1 then do something?

[compact cape]

Just updates some data in the plugin

[sterile token]

Is this okay or will make tps going down?

[compact cape]

me.WHAT YOU HIDE.skywars 🤦‍♂️

[umbral socket]

yes

[kind hatch]

Unless players are being constantly damaged, you shouldn't see a TPS drop.

[heavy marsh]

The issue is that event.setCancelled(true); is called in the onBlockBreak method, ok. And then, I have custom handling for breaking the block, line 60 if (lockedContainer == null || !cancelled) { only passes if the person who breaks the block is the owner (I have logged it), but if someone tries to break the block who isn't the owner the block is still broken (it uses the default breaking logic). Which means that the event.setCancelled(true) is not stopping them from breaking the block.

[compact cape]

That's the package not skywars 🤦‍♂️ 🤦‍♂️

[sterile token]

Allright i ask because someone told that doing .contains() many times on event can cause tps issue. Thanks

[kind hatch]

Ehhh, it depends on the context.

[umbral socket]

so what am I supposed to do

[kind hatch]

Player damage isn't that taxing.

Your contains lookup may be depending on how big the list is.

[compact cape]

2 Words LEARN JAVA 😵‍💫

[umbral socket]

ok then

[quaint mantle]

.contains() on a list is an O(N) operation
if you want to speed it up you can trade space complexity for time complexity by using a hashset or hashmap
because those use underlying hash tables, .contains() on those are near O(1)

[opal juniper]

i thought they were O(1)

[kind hatch]

Ok, even more confusion here. Your method name is #destroyLockedContainer() Implying that if it was true, you would allow the container to be destroyed. Your very first check in that method returns true if the player isn't the owner of that container.

[quaint mantle]

contains on a hash table?

[opal juniper]

yes

[quaint mantle]

most of the time

if your hash function has a collision it will be slower

[heavy marsh]

what do you want from me?? 😢

[quaint mantle]

well i guess it'd be more accurate to say its O(1) average case

[ivory sleet]

which is bound to happen as soon as your V instances scale up

[kind hatch]

Clarification :3

[heavy marsh]

ill fix the returns then, hold on. the destroyLockedContainer method use to be used to determine whether to cancel the event or not but then I realised I needed custom block break handling

[quaint mantle]

also i havent touched plugins in a while and im trying to make a basic one rn, what am i supposed to name the groupid and artifact id?
im following the guide from apache maven and i got something in this format:

GroupID: com.username.plugin-name
ArtifactID: plugin-name
Main Class Name: com.username.pluginname.pluginname.PluginName

this seems horrible, i have to be doing it wrong right

[ivory sleet]

group id is just the reverse of a domain (preferably one you own)

[quaint mantle]

i dont own any domain

[lost matrix]

Thats the standard

[ivory sleet]

dont u have github or sth

[quaint mantle]

oh yeah i do

do i just put io.github.username

[ivory sleet]

some do like io.github.<ghname> or whatever

ye sth like that

[quaint mantle]

gotcha

[kind hatch]

If you didn't have one of those, then the format would be me.my-name.my-plugin-name

[sterile token]

why using own domains ?

[quaint mantle]

thanks Conclure

[ancient plank]

you don't put the plugin name in the gorup id tho

[sterile token]

I always use: dev.alex.net and i never buy it

[ivory sleet]

tho with that being said

artifact id throws me off sometimes also

some people put their project name + module, for instance spigot-base-api whilst some have just api where the group id is supposed to clarify the project

[sterile token]

Is correct this

[heavy marsh]

there, less confusing
https://github.com/Synthetic-Dev/LockedContainers/blob/main/src/main/java/me/syntheticdev/lockedcontainers/events/BlockListener.java#L59

[sterile token]

When i have multiple multi module project i use for parent=dev.alex.net.<project> and for modules=dev.alex.net.<project>.<module-name>

[quaint mantle]

so in ur second example the groupid would be like io.github.username.spigot-base and the artifactid would be api?

[kind hatch]

Does it solve the issue though?

[tranquil viper]

https://www.spigotmc.org/resources/tnt-tag-minigame-bungeecord-recoding.43672/

I have this plugin. It is requiring NMS 1.18 which isn't included in the src. I tried to take a look at the src to see if I could add it but everything is obfusucated. Anyone know if there are any fixes?

[kind hatch]

That just means that it needs to be run on a 1.18 server.

[sterile token]

Or use PTC lib?

[quaint mantle]

i dont think i have multiple modules at all

its gonna be a very simple plugin

[kind hatch]

PTC lib? What's that?

[sterile token]

PTC lib = prtocol lib

[ivory sleet]

yes well for instance
as far as I understood it

either
com.google.gson:gson
or
com.google:google-gson

[quaint mantle]

gotcha

[ivory sleet]

which is annoying, cause afaik there's no rule which one is wrong

[kind hatch]

I don't think ProtocolLib is the issue here, otherwise it would be a simple fix.

[quaint mantle]

aight thanks

have you tried to read the error message that intellij probably shows you?

Yes, Inventory doesn't have any getTitle() method. You can get the title from the InventoryView instead

it's a bad idea though to check your inventories by their title

you should rather keep all your created inventories in a collection and check if it contains the clicked inventory instead

get the InventoryView from the event, and then get the title from that

why would a permission not get registered? If it only exists virtually?

[lost matrix]

Some people just check permissions like this:

player.hasPermission("some.plugin.permission")

And spigot has no way of knowing that this string exists.

yea thought so

but i meant more along the lines

does a permission get registered if it is in plugin yml as a command permission, but not an explicit permission in the permissions section

yes

Location is ConfigurationSerializable. You can just store it on a FileConfiguration

[acoustic pendant]

but i need the world

[chrome beacon]

Your message isn't a valid UUID

[lost matrix]

"0/60" is not a valid UUID

[lost matrix]

So?

[crimson scarab]

what is invalid about it

[lost matrix]

Its not a UUID

1c58dbdc-88ec-496e-b9c5-dd21f78c4884
This is a UUID

[crimson scarab]

then why does it want a uuid if it should send a string

[ivory sleet]

new UUID(counter,cooldown)

[wet breach]

UUID.fromString(message) this method here doesn't create a UUID

[lost matrix]

Because you are calling UUID.fromString(message)?

[chrome beacon]

It's the UUID of the sender iirc

That you're supposed to give it

[lost matrix]

Huh?

[chrome beacon]

You can really give it anyting though

Wait not a chat message

Nvm

[lost matrix]

public void sendMessage(@NotNull ChatMessageType position, @NotNull BaseComponent... component)

[chrome beacon]

Wait nvm on that nvm

The UUID is the sender

[lost matrix]

But its not needed

[chrome beacon]

Which in this case doesn't matter

Yeah

Yes

[crimson scarab]

no luck as of far

[chrome beacon]

Read this and use it together with what smile sent

[crimson terrace]

im having a problem where Bukkit.getWorld() doesnt get a world with a custom name... anyone know about this?

[crimson scarab]

does this mention actionbar

[lost matrix]

Its probably not loaded

[crimson terrace]

they say that they are in that world with their character

[lost matrix]

then the names dont match

[glossy venture]

isnt there a way to display items on hover?

[crimson terrace]

they do. at this point I think they are in a differently named world

[glossy venture]

of a chat component

[chrome beacon]

That would be the ChatPosition in the method smile sent

[glossy venture]

like an item stack render

or is that a md

mod

[chrome beacon]

Mod

Rendering is client side

[feral prairie]

how can i make a file ?

and a directory

[chrome beacon]

https://www.w3schools.com/java/java_files.asp

[feral prairie]

no no

i already have that

but is there a way to make it already go into the sever area

[chrome beacon]

Call your code somewhere and use getDataFolder for your plugin folder

[lost matrix]

Sure. Java is turing complete. You can do whatever you want (as long as the executing user has the permissions)

[hasty prawn]

SHOW_ITEM action when you're making a HoverEvent for a TextComponent iirc

[humble tulip]

getDataFolder.getParent

[glossy venture]

ah

[crimson terrace]

I shall delay the getting of the worlds a few seconds, that should do it

[feral prairie]

the first part is red and doesnt have an import class varible

[chrome beacon]

You need to call it on your plugin instance

[feral prairie]

wdym

[chrome beacon]

An instance of your plugins main class

Or just do it in there
