What is the most efficient way to load data from a user friendly configuration file to the server's memory?

[young knoll]

YamlConfiguration.loadConfiguration

[rare rover]

okay so, i'm working on an SQLite database for my plugin and i was wondering if i should store all the information in a Map instead of retreving the playerdata everytime the player joins. And if i dont do that how would i make leaderboards since it wouldn't be stored on a map therefore cannot sort without retreving all the data again which doesn't seem like the best way. But if i make it all load onto a Map it'll use up alot of ram

i need someones opinion

[young knoll]

Load player data when they join

Use a query to make a leaderboard

You can cache said leaderboard and refresh it regularly if you wish

[rare rover]

okay, you are referring to putting it into a Map / TreeMap for top 10 players

correct?

and make it update every like 5 minutes or so

[young knoll]

Mhm

[rare rover]

okay, thank you. I will work on that

[humble tulip]

Is it possible to put components on itemstack lores and if it is, do translatable components work in lore?

[young knoll]

Not yet

Not with the api anyway

[humble tulip]

With nms it's possible?

[young knoll]

Yes

[true perch]

I'm trying to save a list of Enum names to a config file. Not sure how to do it. Here's what I have:

config.set("Attributes", itemData.getAttributes());```Here's what it does:```java
Attributes:
- !!me.combatborn.realms.mechanics.realmitem.ItemAttributes {}
- !!me.combatborn.realms.mechanics.realmitem.ItemAttributes {}
- !!me.combatborn.realms.mechanics.realmitem.ItemAttributes {}```

Any suggestions?

Thank you

[regal scaffold]

That sounds interesting, if you get it done please send it hear sounds really cool

[young knoll]

Hopefully that api will come through soon

[humble tulip]

How?

[young knoll]

I can’t really give much direct advice without the code in front of me

But you should be able to convert bungee components into their minecraft counterparts, and then work with them directly with the NMS version of an ItemStack

[humble tulip]

Alr ty

I'll have a look

[regal scaffold]

Any ACF tryhard online again?

Is it possible to hide a subcommand in autocomplete, like when a player starts typing a subcommand it doesn't show in the list

So a "hidden" but available command

[echo granite]

Yes

It's annotation whose name I forgot

go to the wiki, they have an Annotations section

[regal scaffold]

Oh I will look in the docs

Thanks!

[wise mesa]

can I register a service provider during onLoad

or do i need to wait until onEnable

i want other plugins to be able to load my service during on load

[lost matrix]

What Nat told you is poop. Just use "@nothing" as second completion parameter.
So

@CommandCompletion("@contacts @nothing")

And dont use a String... at the end.
Just use a String. The last String can contain spaces on default.

@Subcommand("text")
@Description("Text a contact.")
@CommandCompletion("@contacts @nothing")
public void onTextCommand(Player sender, String phoneNickname, String message) {}

The phoneNickname is single on default and message will contain the rest of your input

[regal scaffold]

Oh

Thanks smile

[young knoll]

💀

[regal scaffold]

Will do the changes right now

I have a question

I know that UUID doesn't have a serializable option

So I'm pretty sure using UUID.toString() is the best way

Would it be worth making a class that extends UUID and implement Serializable into that

[humble tulip]

You can serialize uuid to 2 longs

[regal scaffold]

To straight up serialize it instead of toString

[lost matrix]

"best" in terms of readability.
But in reality a UUID is just a 128bit number and can be stored in two 64 bit longs.

[regal scaffold]

Is that the best aproach?

Like, efficiency wise?

[humble tulip]

Yes

[regal scaffold]

Is it that much better than just a String?

[young knoll]

Yes

[lost matrix]

Depends on how you define good for your serialisation

For readability its horrible

[regal scaffold]

Wait so you're saying on a big program, storing UUID as 2 longs would be noticeably better than 1 string? performance wise

I can imagine having to split it into 2 longs is.... tough for the eyes

[lost matrix]

And for performance it depends on your persistency system. How good can you handle 128bit numbers

[humble tulip]

If your program serializes and deserializes them a lot

[regal scaffold]

Alright I see, thanks for the clarification

I wonder if 128bits is too much

[humble tulip]

??

[regal scaffold]

And could probably have a custom UUID which is just 64bits

[humble tulip]

You can

[regal scaffold]

128 seems overkill

[humble tulip]

Just let the first long be 0

[young knoll]

How many uuids are you storing

[humble tulip]

Technically

[lost matrix]

If your serialisation system relies on reading two strings and parsing them into two longs then
the performance might be not too far off from just storing a single String.

[hybrid spoke]

what even are 'yall on about

[rough ibex]

uuids

[hybrid spoke]

just convert the uuid to a string and get the bytes

done

[lost matrix]

With 64bit you couldnt even create enough minecraft accounts for 1/4th of the human population

[regal scaffold]

But

Will your java plugin

Really need to create

[lost matrix]

meh. If you store it as bytes then i would def prefer the msb/lsb approach

[young knoll]

128 bits is nothing

[hybrid spoke]

also possible but in the end of the day it doesnt really matter

[regal scaffold]

5.3 x 10^36 possible choices

[hybrid spoke]

you have to deconstruct and construct it again anyways

both ways are fast

[echo basalt]

fun fact: it is not

[regal scaffold]

tf really

[hybrid spoke]

if you aren't gonna do it multiple million times at once its wayne what method you choose

[rough ibex]

is this a microoptimization

[hybrid spoke]

yes it is

[rough ibex]

(maybe)

[young knoll]

What’s that like 8k uuids in a megabyte

[regal scaffold]

1,099,511,627,776

[echo basalt]

if you have 1 billion unique users

that's like 16gb

[regal scaffold]

Are you really gonna need that many

unique identifiers

[hybrid spoke]

0.12mb

[young knoll]

Yes

[echo basalt]

you can get a 240gb ssd for 15$

[regal scaffold]

1,073,741,824

[echo basalt]

that's about 1$ / billion uuids

[rough ibex]

what a deal

[regal scaffold]

1,099,511,627,776 > 128bit
1,073,741,824 > 64bit

128bit is not 1bil. it's 1tril

[young knoll]

It’s more than that

[regal scaffold]

No?

16^10

Oh wait

it's not ^10

[humble tulip]

2^128

[echo basalt]

what you on about

2 ^ 128

[hybrid spoke]

are we topic hopping or what are we on about rn

[regal scaffold]

Didn't we just say it was hex

[young knoll]

128 bits, each bit has 2 states

2 ^ 128

[regal scaffold]

3.4028237e+38 -> 2^128
1.8446744e+19 -> 2^64
4294967296 -> 2^32

That definately seems overkill for... anything

But I guess I'm wrong

[young knoll]

I’m sure people said that about ipv4 too

[humble tulip]

That's what we thought with ipv4

LOL

[young knoll]

UUIDs are meant to be universally unique

[humble tulip]

Same thing

[regal scaffold]

Not even close

IPV4 was like 4.3 bil

Total

[young knoll]

So I don’t want any uuid collisions with any aliens out there

[rough ibex]

"Nobody will ever need more than 640k RAM"

[regal scaffold]

You can't compare 4.3bil with 3.4028237e+38

[hybrid spoke]

say that to my java program

[young knoll]

Keep in mind every entity you spawn in minecraft has a uuid

[echo basalt]

you'd need 2^65 exabytes to store all the uuids that could ever exist

[young knoll]

Granted those really only need to be unique across one minecraft server

But still

[regal scaffold]

340,282,370,000,000,000,000,000,000,000,000

That's the actual number

[hybrid spoke]

keep in mind that UUIDs aren't only used for minecraft

[regal scaffold]

vs 4,300,000,000

Yes but

We're a minecraft community

[river oracle]

Just don't use uuid if you think it's overkill

Your issue

[young knoll]

Still less than the number of ways to shuffle a deck of cards

[hybrid spoke]

yeah stay native

[regal scaffold]

We were just talking about micro optimizations

[humble tulip]

Use int or sumn

[young knoll]

Use a byte

[hybrid spoke]

better go machine code

[young knoll]

256 options, take it or leave it

[regal scaffold]

Cause instead of storing a UUID as 2 longs, you can most likely get away with just as 1

[hybrid spoke]

or write it on paper

[regal scaffold]

I think assembly is indeed the better choice here

[hybrid spoke]

no its not

[rough ibex]

aren't UUIDs like impossible to collide because the first part is timebased

[hybrid spoke]

they can collide

[rough ibex]

in what scenarios

[hybrid spoke]

if you create enough at the same time

like 1 bil within a ns or smth

[regal scaffold]

lol

[hybrid spoke]

ah per second

[rough ibex]

Of course not

[hybrid spoke]

chatgpt ftw

[regal scaffold]

TLDR of micro optimization

Just use UUID

I'm curious if it actually wrote it correctly lol

[young knoll]

¯_(ツ)_/¯

Anyone have NASM installed

[wet breach]

Also there is the probability in creating a duplicate on first time as well as shorter times just because

[regal scaffold]

Interesting

Thanks!

And last question for the night

Lets say I want to store a simple "date" in a object that gets written to a file:

DD-MM-YYYY-TIME

dateTimeFormatter.format(LocalDateTime.now())

I assume this is not serializable

[young knoll]

It should be possible to just store it as a timestamp

[regal scaffold]

OH!@

Yes!

[young knoll]

Provided you don’t need to go earlier than 1970

[regal scaffold]

Current so nop

Thanks

How do I get the timestamp

[lost matrix]

SImplest way is System.currentTimeMillis()

[regal scaffold]

I need something more readable

[lost matrix]

Well then you cant use a timespamp

[regal scaffold]

Could I just store it as a string?

[lost matrix]

Use Instant now = Instant.now()
It can be serialized pretty easily

[regal scaffold]

idk how hard it would be to convert it back

Oh

Ok

        map.put("timeSent", timeSent.toString());

        Instant timeSent = Instant.parse((String) map.get("timeSent"));

Logically makes sense I wonder how the format is

[young knoll]

Shouldn’t be too hard to format System.currentTimeMills into something readable

[regal scaffold]

Any preferred collection system to be able to sort Collection<Object> by a field inside the object?

[young knoll]

DateTimeFormater should work

[regal scaffold]

I was using this just not sure if it's serializable

[young knoll]

You serialize the milliseconds

And then format it for display

[regal scaffold]

I think if I make my Object implement Comparable<Object>

[lost matrix]

You have to serialize the Instant using the DateTimeFormatter#ISO_INSTANT
If you want to parse it again

[regal scaffold]

Ohhh ok ok

[lost matrix]

    Instant now = Instant.now();
    DateTimeFormatter formatter = DateTimeFormatter.ISO_INSTANT;
    String serialized = formatter.format(now);
    
    Instant deserialized = Instant.parse(serialized);

[regal scaffold]

Now that, is really cool

I like that

[young knoll]

If you’re able to keep it stored internally as a long I’d do that

And then parse it when displaying it to players

[regal scaffold]

Indeed

Pretty slick

Any preferred collection system to be able to sort Collection<Object> by a field inside the object?

Like lets say I want to keep the list organized

[young knoll]

Do you want it to automatically sort

[regal scaffold]

Sorted by, what we just did, date

[lost matrix]

PriorityQueue for example.
Or TreeSet

[regal scaffold]

Yes!!! I forgot about those, I couldn't remember the name

[lost matrix]

You just need to pass a Comparator to the constructor

[regal scaffold]

    @Override
    public int compareTo(Text other) {
        return this.timeSent.compareTo(other.timeSent);
    }

Are you sure I can't just implement Comparable<Text>?

[lost matrix]

  public static class SomeClass {
    private final long timestamp;

    public SomeClass(long timestamp) {
      this.timestamp = timestamp;
    }
    
    public long getTimestamp() {
      return timestamp;
    }
  }
  
  private final TreeSet<SomeClass> sorted = new TreeSet<>(Comparator.comparingLong(SomeClass::getTimestamp));

[lost matrix]

Oh yeah. You can also let your class implement Comparable<Self> and not pass a comparator

[regal scaffold]

Sickkk

Is Set<?> serializable

How can I know if it is

I want to be able to stop asking

Looking at the javadocs is there any way to tell?

[young knoll]

Serializable to what

ConfigurationSerializable?

[regal scaffold]

YAMLConfiguration

Yes

[young knoll]

I don’t believe set is

List is

[regal scaffold]

But how can I know without having to ask each time, there's got to be somewhere to look

And if it's not... annoying

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[lost matrix]

Try it out. Havent used spigots serialization in a while.
If not then try adding set.toArray()

[regal scaffold]

There's really no way to know looking at docs/implementation?

[young knoll]

Well classes will implement ConfigurationSerializable

But obviously java classes don’t have that

[regal scaffold]

Why does List do it then

?stash

[undone axle]

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

[lost matrix]

Other than that Map and List are natively representable in yaml

[young knoll]

Spigot handles various objects from the standard java library

I’m not sure if they are listed anywhere

[regal scaffold]

So try and error

Fair

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/configuration/serialization/ConfigurationSerialization.java#31-32,47,56,166,174,176,185,252,259,266,271,278

[young knoll]

So if it’s a Bukkit object check for the interface

If it’s a standard java object then yeah, idk

I do know all primitives work, as well as lists and arrays

I’m sure there is more

[regal scaffold]

set.toArray will do

If I'm doing toArray to serialize

What am I deserializing to

[lost matrix]

List and then passing it to the TreeSet i guess

[regal scaffold]

toArray does a list?

So confusing...

[lost matrix]

There is no diff between array and list in yaml

[regal scaffold]

Oh

            Set<Text> phoneTexts = new TreeSet<Text>((List<Text>) phoneData.get("phoneTexts"));

Jesus lol

[lost matrix]

Call getList

[regal scaffold]

It did not like that

[high igloo]

hello, is there a way to set the light level without using light blocks

[regal scaffold]

Oh wait I still need to cast

[young knoll]

Not with the api

[lost matrix]

You need to cast as well

[regal scaffold]

Does it even matter then?

I'm brain melted for tonight

I need sleep

Thanks for the help

I can say tho

It worked

Like a charm

Jesus

That is so damn cool

[young knoll]

What

You can index any java array like that

[regal scaffold]

Opinions on Adventure?

[young knoll]

Alone it’s not much different than bungee components

But if you use minimessage to parse stuff it can be quite useful

[regal scaffold]

I searched on how to do BaseComponents with config files and the first answer was using Adventure was a good option

[buoyant viper]

TextComponent.fromLegacyText go brrr

adventure probably is the better option bc u can use minimessage for some cool parsing

like clickable text and hover stuff

all stuff u can do with Spigots components too, but no built-in parser :v

Why does serialized ItemMeta not serialize back properly via ConfigurationSerialization? Result:
```[Server thread/INFO]: Expected: ItemStack{DIAMOND_SWORD x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, enchants={DAMAGE_ALL=5, FIRE_ASPECT=2, SWEEPING_EDGE=3}}}
[Server thread/INFO]: Actual: ItemStack{DIAMOND_SWORD x 1}```
this is on 1.19.4

Figured out the issue, the format of serialized ItemStacks must have changed at some point

item meta used to be under the key "meta", now it's "UNSPECIFIC_META"

That doesn't sound right, are you confusing with .toString

[static ingot]

It serializes back correctly after changing it to that ¯_(ツ)_/¯

I'm only using the #serialize methods

[quiet ice]

Are you using spigot spigot or something else?

If I had to guess different servers could produce different outputs

[static ingot]

It's Spigot. 1.19.4. lol

not any fork

[quiet ice]

strange

[lost matrix]

For what purpose are you doing this?

[static ingot]

gson deserialization via Bukkit's ConfigurationSerializable API

though i just realized i was printing the string value of the item stacks rather than the serialized maps after all, lol

I'm still looking into it more

[lost matrix]

Have you tried simply throwing the map into gson?

[static ingot]

err. personally, no. but afaik that would throw errors because ItemMeta is just an interface

Unless I'm misunderstanding what you mean

[lost matrix]

Does the serialized ItemStack have to be readable?

Or is it only for persistence

[static ingot]

Readability is preferred since it's part of the main config

[lost matrix]

Then you should not use json...

[static ingot]

¯_(ツ)_/¯

[valid solstice]

I can't see my arms, hotbar, and others when i do Player#setGameMode(GameMode.SPECTATOR). How do i make them visible while in spectator

[icy beacon]

That's the normal behavior of spectator mode, and pretty sure it's clientside

[valid solstice]

oh so how about hypixel? how do they do that?

[lost matrix]

They simply hide the player from others

[valid solstice]

Yea how?

[lost matrix]

Nobody can answer that for you.
But the spigot way is just Player#hidePlayer(Player)

[valid solstice]

oh so i hide one player to another player

[quiet ice]

If I had to guess - some packet shenanigans.
Nothing too complicated

I'd not recommend that route though unless performance is important

[quaint mantle]

hey guys

[quiet ice]

hello there

[quaint mantle]

can somone tell me how to check blockstate ? (i wanna know if a furnace is lit or not)

i tried e.getBlock().getState()
but when i do BlockState. there is no block State To compare

Is there a way to do it without nms and packet?

[quiet ice]

Cast it to the block state you want it to be

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[quiet ice]

So ((org.bukkit.block.Furnace) e.getBlock().getState()).getBurnTime() > 0

[quaint mantle]

oh lol i was trying to cast BlockState. itself , thx a lot mate <.3

[quaint mantle]

quick questoin
I have 2 types of a block in my plugin when i they both are supossed to triggera diffrent listeners. Whats the best identifier to set for the listeners to regonize them

[rotund ravine]

What type of blocks

[quaint mantle]

Barrels

[lost matrix]

In this specific case you could store data in the PDC of the barrels

[quaint mantle]

oke

hey guys, can someone tell why when i cast a block when i call its method its doesn't return anything ? i mean

why this work

but this one doesn't
Bukkit.getServer().getPlayerExact("__Mental_").sendMessage(((org.bukkit.block.Furnace)e.getBlock()).getWorld().toString());

[lost matrix]

This throws an exception

You can cast Block to Furnace

[pine forge]

Hey, ive never really understood how these namespaced keys work when im creating a recipe or using the persitentdatacontainer on items.

Is it valid to use NamespacedKey.minecraft("recipe_name") or should you use new NamespacedKey(this, "recipe_name") (or "item_name")?
What is the difference?

[rotund ravine]

One adds minecraft as the namespace the other uses your plugins name.

[pine forge]

Okay but what actually is a namespace and is it recommended add stuff to minecraft's namespace?

[rotund ravine]

It is not

minecraft:xxxx
yourplugin:xxxx it’s a way to easily differentiate keys.

[pine forge]

okay, why are you not supposed to add stuff to minecraft's namespace?

[rotund ravine]

Because it’s not yours

Simply said.

[pine forge]

okay

[lost matrix]

You should not add keys to any other namespaces than your own in general

[pine forge]

shouldnt the method be deprecated then or something?

[rotund ravine]

It’s not an old festure

[lost matrix]

It has its use cases if you want to create namespaced keys for minecraft resources

[rotund ravine]

It’s useful when you know what to use it for.

[pine forge]

examples?

[lost matrix]

vanilla recipes

[quaint mantle]

can you explain more ? i should throw what exception ? and is this a proper way to do it ? i wanna check if a furnace is lit or not by casting it to furnace and the get the burn time

[lost matrix]

Cast the BlockState of a Block to Furnace and check

[quaint mantle]

thx mate

[quick sail]

if im making an RPG plugin, I obviously need to hold some additional variables that "belong" to the player object. My solution to this is basically creating a PluginPlayer class that holds my additional data. Of course then I need a way to get a PluginPlayer from a player since all bukkit api gives me are regular Player objects so I store a map of UUID - pluginplayer pairs for all currently online players and pass that in to whatever needs it. Am I on the right track with this or is there a more elegant solution I'm missing.

im a bit of an amateur

[lost matrix]

This sounds like the proper approach. A manager class which holds a Map<UUID, RPGPlayer>.

[quick sail]

should my "RPGPlayer" hold a copy of the Player object too? That was my original plan but I feel its not needed at all

[lost matrix]

please make agility less grindy if you implement it btw

[lost matrix]

Never hold references to live objects like Player, Entity, Chunk etc.
If you need a reference then use an identifier like the UUID.
I would add the players UUID so that you can actually get back to the player
object when needed.

[quick sail]

that was what I figured, would you care to explain why not to hold live objects

doesnt need to be basic explanation or anything

I like to learn

[remote swallow]

for context the player one is invalid as soon as they logout

[ivory sleet]

they're fragile

[quick sail]

that could be handled

[lost matrix]

It easily leaks memory by preventing the garbage collector from collecting it

[ivory sleet]

these objects usually have a lot of state

[quick sail]

that makes sense

[ivory sleet]

yes you can always handle a Map<Player,V>

but is it a good approach?

[tardy delta]

WeakMap

[ivory sleet]

which is works but is still gc dependent

[tardy delta]

it will get gced, the question is when

[lost matrix]

Has anyone here sent custom advancement messages? Im a bit lost.

  public static void sendAdvancement(Player player, ItemStack icon, Component title, FrameType frameType) {
    DisplayInfo displayInfo = new DisplayInfo(icon, title, Component.literal(""), null, frameType, true, true, false);

    Criterion criterion = new Criterion(new NotifyTrigger());

    AdvancementRewards rewards = AdvancementRewards.EMPTY;
    String[][] requirements = {{criterionId}};
    Advancement advancement = new Advancement(identifier, null, displayInfo, rewards, Map.of(criterionId, criterion), requirements);

    AdvancementProgress progress = new AdvancementProgress();
    progress.update(Map.of(criterionId, criterion), requirements);
    progress.grantProgress(criterionId);

    ClientboundUpdateAdvancementsPacket packet = new ClientboundUpdateAdvancementsPacket(true, List.of(advancement), Set.of(), Map.of(identifier, progress));

    ServerGamePacketListenerImpl connection = ((CraftPlayer) player).getHandle().connection;
    connection.send(packet);
    connection.send(removePacket);
  }

[remote swallow]

for a toast message? or just a custom advancement

[lost matrix]

Just the toast message on the top right corner

[tardy delta]

doesnt alex have a lib for those toast messages

[lost matrix]

So adding an advancement and then instantly completing it

[ivory sleet]

yes which is a problem is u do certain types of test

and debugging where u use epsilon for instance

[tardy delta]

hmm?

to check for integrity for example?

[lost matrix]

Where does he translate this into a packet?

[remote swallow]

one moment

[ivory sleet]

well epsilon is a special type of gc that doesnt really free memory

[remote swallow]

https://github.com/JEFF-Media-GbR/JeffLib/blob/master/spigot_1_19_4_R1/src/main/java/com/jeff_media/jefflib/internal/nms/v1_19_4_R1/NMSHandler.java#L374-L384

[tardy delta]

ah

[ivory sleet]

and problem with weakhashmap is also that it just doesnt prevent gc, like assuming gc doesnt sweep for a while (which can be the case for some gcs wherre it doesnt happen for a longer time), then the object can be strongly reclaimable also

[lost matrix]

I dont want to register the advancement anywhere. The message is steteless. This sadly doesnt help much.

[opal juniper]

roasted

ive defo seen it done tho... hmm

[humble tulip]

Does bukkit store strong references to bukkittasks?

[tardy delta]

yes?

[ivory sleet]

for some time yes

[humble tulip]

Until cancellation?

[tardy delta]

as long as they are scheduled ig

[ivory sleet]

ye minion

[quick sail]

Do any of you guys have a good reference that goes in depth on the garbage collector

[humble tulip]

So i can put bukkittasks in a weakhashset to cancel the ones that haven't been cancelled?

[quick sail]

I have a rough idea but my brain doesnt work unless I fully understand things

[lost matrix]

Else they would just vanish into oblivion

[lost matrix]

You should in generall not worry about that

[quick sail]

I wish it was so easy

[ivory sleet]

there are like 7 gcs in total

and so many options

like jvm flags

[quick sail]

yeah i know

but like, I need to understand

[humble tulip]

I know calling cancel on a already cancelled task is fine

So what i really wanna know is if it's psossible for currently shceduled tasks to be gced

You said bukkit keeps a reference so i assume it isn't

[tardy delta]

should look into those different types of gc

i only know minor and major 💀

[ivory sleet]

learn zgc and g1gc

other ones are redundant for u rn i think

[quick sail]

I guess I'm just trying to understand what the inherent flaw would be with storing references to player objects in regards to the garbage collector

that storing references to "RPGPlayer" objects wouldnt have also

[tardy delta]

ZGC performs all expensive work concurrently, without stopping the execution of application threads for more than 10ms 10ms 😳

[ivory sleet]

its configurable but ye

[final monolith]

BaseComponent

As i know, the default bukkit api doesnt supports

Title creation with base components

[wet breach]

The main problem is accidentally holding a reference to a player object when said player has disconnected. The object becomes invalid even more so if they reconnect. This is in essence a memory leak because you have retained something that was marked invalid

[quick sail]

Okay I think I got you, to clarify if I create an RPGPlayer object when a player joins, I'd have the same exact issue if I didn't clean it up on disconnect

[wet breach]

But so as long a single reference is held the gc cant collect it and dispose of it

[wet breach]

Depends on your object. The player object is tied to server internals and api. Where as your object doesnt have to be

[quick sail]

or is that still me misunderstanding

okay yeah that I think makes sense

[quaint mantle]

is a barrel a tile entity?

was like a 10 second search nvmö

[rotund ravine]

Should be

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[rotund ravine]

Any block storing data is a tilentity

[wet breach]

Think they are called block entities now

[wet breach]

Feel free to ask more questions. Plenty of us here who are well versed. You can store a player object reference just really need to be careful and since it is easy to lose track where you have references, it is the reason we always recommend not storing the player object and instead uuid since that is still unique and can be used to obtain a valid player object if it is needed

[quick sail]

Yeah I've already decided I'm going to go the UUID route, just makes more sense in every way.

I'm mostly self-learning to code and really trying to focus on doing things the right way

[wet breach]

Well at least you are smart enough to actually seek out those who may know the answer instead of just assuming lol

[rotund ravine]

And asking in a coherent and polite way

[wet breach]

And that too

[quaint mantle]

how do i set a block with a pdc

or well a tile entity

[regal scaffold]

Well I was hoping to be able to conveniently customize the hover event, clickable events and colors from config

[rotund ravine]

?pdc

[undone axle]

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

[rotund ravine]

Not sure if this mentions it

[quaint mantle]

i find nothing online about it what so ever

nvm its in there

[buoyant viper]

then yeah, Adventure :p unless u want to make ur own format&parsee

[sullen marlin]

Json format, same as /tellraw is always an option

[quaint mantle]

i think im gonna go insane

why is this so complicated

nothing makes sense

pls help

[tender shard]

for blocks you can use CUstomBlockData

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[regal scaffold]

Alright thanks

[granite owl]

xD

[lost matrix]

Yo alex, maybe you got an idea what im missing here. Im trying to send a toast message by simply adding it, sending
a completed progress in the same packet and sending a removal packet afterwards.

  public static void sendAdvancement(Player player, ItemStack icon, Component title, FrameType frameType) {
    DisplayInfo displayInfo = new DisplayInfo(icon, title, Component.literal(""), null, frameType, true, true, false);

    Criterion criterion = new Criterion();

    AdvancementRewards rewards = AdvancementRewards.EMPTY;
    String[][] requirements = {{criterionId}};
    Advancement advancement = new Advancement(identifier, null, displayInfo, rewards, Map.of(criterionId, criterion), requirements);

    AdvancementProgress progress = new AdvancementProgress();
    progress.update(Map.of(criterionId, criterion), requirements);
    progress.grantProgress(criterionId);

    List<Advancement> advancements = List.of(advancement);
    Map<ResourceLocation, AdvancementProgress> progressMap = Map.of(identifier, progress);
    ClientboundUpdateAdvancementsPacket packet = new ClientboundUpdateAdvancementsPacket(true, advancements, Set.of(), progressMap);

    ServerGamePacketListenerImpl connection = ((CraftPlayer) player).getHandle().connection;
    connection.send(packet);
    //connection.send(removePacket);
  }

The advancement is there but i dont get a toast (presumably because the progress is not properly completed)

[echo basalt]

that's fun

[quaint mantle]

Hey, been a while since I've done anything Minecraft related, I can't seem to build my plugin using the shade:shade goal, saying Failed to create shaded artifact, project main artifact does not exist.

I'm not sure what could cause this, any info would be greatly appreciated

[quiet ice]

Use package instead

[quaint mantle]

That doesn't put all the libraries in, right?

[quiet ice]

Assuming you have set up the maven-shade-plugin correctly

send the pom

[quaint mantle]

Sent you a friend request

[echo basalt]

what if you add a trigger to your criterion

[quaint mantle]

If I run package -f pom.xml i'll run into ClassNotFound exceptions

[quiet ice]

what the friggn hell

[granite owl]

can anyone confirm that the JNI's jni.h header wrongly includes the jni_md.h file under the windows 64 bit version of literally any jdk version? xD

[quiet ice]

The JNI header has traditionally been broken. So could be.

[granite owl]

xD

[wet breach]

it is not wrongly included

you need to include the appropriate directory which is platform dependent

[granite owl]

from my jdk, the jni_md.h is under the win32 sub directory and the jni.h

#include "jni_md.h" without the sub dir

and this is since jdk 9 or so

[wet breach]

include the appropriate directory....

which again is platform dependent hence why it isn't there automatically

[granite owl]

as in they expect me to modify the header or in the project settings?

[wet breach]

if you don't want to bother with compiling it yourself then get a precompiled binary

[quiet ice]

It's a header ... you don't compile a header

[wet breach]

but a header is needed to compile

[quiet ice]

I'd just edit the header so it works and if it works it works

[granite owl]

xD

[wet breach]

its safe to edit the header since it is platform dependent anyways

that is, whatever it is you are targeting that binary will only work for that platform or similar possibly

[granite owl]

also i installed it from the PUBLIC jdk installer, and the header is licensed as confidential lmao ive already reported this to oracle a year ago with the jdk 18 and they still didnt fix it

[quiet ice]

I mean with JDK 18 you probably want to use panama instead

[granite owl]

17*

but still

how can it happen that they publically release something marked as strictly propritary and confidential

[wet breach]

because header is only needed for compiling it isn't strictly needed depending on what you are doing

[echo basalt]

@lost matrix why are you setting the clearCurrent field to true? that resets advancements

might be why

[granite owl]

yea ofc since i need a jdk for each target platform

[granite owl]

but the linux jdk 20 is marked as open source ^^

[wet breach]

and that means it can't have something proprietary?

[granite owl]

no but its not marked as confidential and NDA'd

xD

[wet breach]

individual files can have their own licenses attributed to them that is separate from the entire project

[lost matrix]

Hm this should only result in the current advancements being removed. Ill try to change it.

[lost matrix]

Ok that was literally the problem...

Makes no sense, but thanks for the input

[granite owl]

about this, i use multiple jdks for each respective target platform and i use conditional compiling to have it work from the same code base

[echo basalt]

I'm magical

my thought was like

you're setting the data and wiping it all away

[wet breach]

https://tenor.com/view/rainbow-unicorn-caticorn-cat-unicorn-taylor-swift-gif-15475737

[quiet ice]

The OpenJDK install I have (under linux) don't have any of such mentions

[lost matrix]

Well but the data is there (As shown in the screenshot). Ive only wiped the old data.

[echo basalt]

well you're wiping away all the progress

because advancements are only registered once

[wet breach]

even if it did, I think they forget that oracle doesn't need to give themselves permission to release something

[granite owl]

yea its only the windows version thats so oddly broken

[granite owl]

but it would limit the end user as to how to use it, for example i cant include it in my projects repo as standalone installation

[wet breach]

then you mis-interpret what it means to be open source

[summer scroll]

I tried to give spawner with different entity but it will turn into a pig spawner when I placed it down even If I try to give myself an iron golem spawner.

    public static ItemStack createMobSpawner(EntityType type, int amount) {
        ItemStack stack = new ItemStack(Material.SPAWNER, Math.max(amount, 1));
        BlockStateMeta bsm = (BlockStateMeta) stack.getItemMeta();
        CreatureSpawner cs = (CreatureSpawner) bsm.getBlockState();

        cs.setSpawnedType(type);
        bsm.setDisplayName(SodeSpawners.color("{type} Spawner"
                .replace("{type}", SodeSpawners.capitalizeFully(type.name().replace("_", " ")))));
        bsm.setBlockState(cs);
        stack.setItemMeta(bsm);
        return stack;
    }

[granite owl]

do u have op? only an admin can place a spawner with meta data

[summer scroll]

Oh really? I didn't know about that lmao.

[granite owl]

otherwise its always defaulting to a pig spawner with empty metadata

[summer scroll]

What would you suggest If I want to give players sheep spawner for example?

[granite owl]

that u cancel the event

and place it with ur plugin

thats what i do

[summer scroll]

But I'm op and it still turns into a pig.

[young knoll]

Manually add the data from the ItemStack to the placed blockstate with the place event

[granite owl]

then ur format is broken

somehow

[granite owl]

or that

that would prevent the block from getting removed and re-placed

[summer scroll]

Alright, I'll do that, thanks guys!

[granite owl]

also @summer scroll try using an online spawner generator that creates a give command just to verify it works at all xD

then u know that something in ur format went wrong

[young knoll]

You would also have to copy the data into an item in the break event

Assuming you want to pick them up with silktouch or whatnot

[summer scroll]

Yeah, I'll remember that.

[granite owl]

that i did with cancelling the drops and instead dropping the spawner block if the item is a pickaxe with silk touch

i mean thats how i made spawners mine-able

in the blockbreak event i think

[young knoll]

I wonder if you took every spigot plugin ever made

What event is used the most

[lost matrix]

You mean as in declared the most or used most amount of times during runtime

[quaint mantle]

interesting

[young knoll]

Declared the most

[quaint mantle]

i think he mean in declared

brock break ?

[lost matrix]

Declared i would say InventoryClickEvent

[quaint mantle]

block *

[granite owl]

onCommand

🐒

[lost matrix]

Because everyone want to add guis nowadays

[quaint mantle]

or intract

interact*

bruh im so bad

[lost matrix]

@austere cove ban pls

[young knoll]

Yeah inv click seems reasonable

[remote swallow]

you know what we can do

make optic run a server with all spigot plugins and run spark

[granite owl]

tbh im astounded by how many times i asked how to write my own command completer and ppl told me it doesnt work

when i finally learned how to dig trough apis and their docs

[young knoll]

As for called the most during runtime imma guess block physics

[granite owl]

theres literally onTabComplete as member of JavaPlugin

[quaint mantle]

☠️

[remote swallow]

its in TabCompleter and TabExecutor too

[lost matrix]

Who told you that it doesnt work?
Sounds like someone who has no idea about Spigot.

[granite owl]

ofc thats where it comes from

[lost matrix]

Also: You should only use that for very small plugins.
For bigger ones you should implement the appropriate spigot interfaces and register
them for each command individually

[granite owl]

as in having a class inherit BukkitCommand and register that?

[remote swallow]

command class extends/implements TabExecutor and you can do it there

[echo basalt]

for really big plugins you make a command system and register each subcommand as its own class

[remote swallow]

why big plugins, i do that for most'

[lost matrix]

[granite owl]

why cant i just have one main onTabComplete and switch trough the command.Name().toLowerCase()

in java strings in switches are hashed anyways

[remote swallow]

you can, nothing stops you

[river oracle]

No you shouldn't really ever use BukkitCommand unless you plan to do something like register them automatically through reflection

[granite owl]

as such there shouldnt be a performance penalty

[remote swallow]

its just not recommeneded

and can get long as hell

[river oracle]

Simple, separation of concerns

[granite owl]

thats what i did before xD

[echo basalt]

switch through the hashcode

[lost matrix]

Because thats dirty

[remote swallow]

is 7smile having a stroke

[granite owl]

xD

before i actually write my plugins i first need to finish my importer for my ini parser (the jni thing) xD

and probably need to find a dedicated server provider since every mc provider is not all too keen of allowing me to use binaries

[echo basalt]

just rent a vps

[lost matrix]

Ignoring the fact that ini is a terrible file format, why would
you want to trouble yourself with jni just to parse some files.

[granite owl]

its not a terrible format lol

its a simple format

a simple format for simple config files

[echo basalt]

this is micro optimization at its worst

you can do byte parsing in java, manually

basic readInt readWhatever, there's no need for jni

[granite owl]

my parser is written to be loaded in various languages, ive finished my c, c++ static and dynamic importers

working on the c# and java rn

and more to come at time

[quiet ice]

readInt
Smh.

[lost matrix]

I would assume that it doesnt even optimize anything unless you are parsing megabytes of data.
And at that point you are missing the point of inis.

The performance is more limited by your hard drive than the language for file IO

[granite owl]

its written in c++ with all the neccesseary memory management and error handling incl. handling bad allocs internally

its not running on asm speed lvls anyways

[lost matrix]

Meh. If you really like tinkering with that then go ahead.
But there is nothing to gain but trouble with this.

[granite owl]

like i said one lib can be loaded from various languages

one code base for multiple langs

[quiet ice]

I always wanted to write a machine code generator lib in java.
Should do it for maximum speed (Yes - nasm exists; but why not generate those executables at runtime?).

[granite owl]

its for me in the first place

if ppl think its a terrible product honestly idm ill release it under the MIT license and while its ofc good to listen to critics

in the end its free

[lost matrix]

GraalVM compiles java into native machinecode

[granite owl]

so if ppl dislike it its not like id lose money since i didnt ask for anything in the first place 😛

[quiet ice]

I'm talking about implementing a machinecode assembler in java

probably already exists though

[lost matrix]

[granite owl]

why exactly

would u want to write a compiler in java

[quiet ice]

Not compiler - assembler.

[lost matrix]

A compiler i would understand

[granite owl]

i dont think its even possible with pure java

iirc ghidras GUI is in java and the decompiler/compiler and disassembler are in C++

[lost matrix]

Fun fact: The java compiler (javac) is written in java

[tardy delta]

me who wanted to create some custom bytecode interpreter in java :(

[quiet ice]

it is possible - but you don't want to.

[granite owl]

idk how deep java lets u dig in its internals tbh

[quiet ice]

I mean it is just writing a file

How hard can it be (outside of reading a LOT of documentation)

[next plume]

You can write an assembler in any language.
I wrote a disassembler in Ada once.

[granite owl]

the hardest will be to read trough the standards how to format ur binaries so that the machine instructions can be read and then u need to have an engine that translates the developers nonsense in primitive usually cisc instructions

[tardy delta]

isnt that just the job of a parser?

[quiet ice]

The binary formatting/packaging will be the biggest pain

[granite owl]

so u need to understand how languages in general work on a basic level

[lost matrix]

Its all just GOTO in the end

[quiet ice]

Jars are so much simpler on that front

[granite owl]

java bytecode will prob be alot easier since oracle could basically define their own instruction set

[quiet ice]

Java bytecode is incredibly easy

[granite owl]

its still terrible to read imo🤣

[quiet ice]

But I've been extensively working with it for the past two years so ...

[lost matrix]

jvm

[wet breach]

lets see how long it takes them to learn that JNI doesn't get optimized by JIT or anything else in Java

[granite owl]

i like that jar files always include a copy of the source code by default

alongside the bytecode

🤣

[quiet ice]

Eclipse moment.

[granite owl]

ya eclipse

though i switched to intellij recently

[lost matrix]

Makes meta programming possible.
And runtime exceptions arent just
You fked up somewhere. Dumped memory

[granite owl]

since my eclipse broke upon trying to update it

[quiet ice]

I just delete the eclipse install folder and start from scratch if there is a serious fault

[tardy delta]

eclipse moment

[paper venture]

I have an entity, I want to deal damage considering entity's armor, how should I do it? Yes there is a formula on wiki, but is there a way without manually calculating this damage?

[glossy venture]

for exception stack trace info you dont need the sources
each class file stores the source file and it uses the methods LineTable or whatever

[quiet ice]

But I have only encountered such a scenario once (which was a CDT install so not that important anyways)

[lost matrix]

I believe that if you damage an entity while providing a damage source the armor and potion effects are taken into account.
But test that theory.

[granite owl]

the moment i dumped eclipse was when i installed the 2023 version and got a warning that there are unsigned dependencies from google and oracle and i must allow to install from unknown sources in order to install eclips

that was my fk it moment

[quiet ice]

I mean coredumps are powerful given that they include the entire state of the machine at the time it crashed.
But you need to correct tooling for it

[quaint mantle]

does this even work? im tryna find out if my mistake is in creating or reading the pdc

[quiet ice]

most likely gson, javax inject and other libs

[paper venture]

But can I somehow nullify knockback effect because of providing a damage source?

[lost matrix]

I dont think this applies a knockback

[paper venture]

If I'm not mistaken it does...

[remote swallow]

that should work

[granite owl]

still that + the fact that eclipse crashes on trying to update it + it being super bloated with features and maven unfriendly which i need for plugins made me dump it in the end

[lost matrix]

if(state instanceof Barrel barrel) {
  ...
  barrel.update();
}

[lost matrix]

🤷

Listen to the EntityDamageEvent, get the final damage and cancel the knockback then

[granite owl]

• my prof suggested intellij anyways for this semester so whatever

🤣

[paper venture]

Okay I will try thanks!

[wet breach]

netbeans exists

[lost matrix]

Then you got an up-to date prof.

Fk frostalf sniped me

Was about to bring up Netbeans

[granite owl]

xD

[quaint mantle]

lucky you

[quiet ice]

maven unfriendly?

[granite owl]

i got a university license for clion and intellij

[quiet ice]

Are you deep in writing maven plugins or something else?

[granite owl]

so i was like sure whatever

[hazy parrot]

Currently working with netbeans at class, this autocompletion is awful

[wet breach]

who knows what they are doing when they decided to use JNI to read a basic ini file

[granite owl]

im not a fan of maven its super bloated in features but it does have benefits like auto updating apis

[wet breach]

bloated?

[granite owl]

external 3rd party apis

like it has so many settings

[hazy parrot]

Why would you auto update libraries lol

[wet breach]

you do realize maven at its core is slim, it only bloats the more plugins you decide to toss into the pom

[quiet ice]

isn't that the whole purpose of a build tool?

Wait until you see make

[granite owl]

to keep my plugins updated with the latest api?

[hazy parrot]

Gl when getting breaking change in minor update

[granite owl]

xD well the ide will show me where

[granite owl]

ya

[wet breach]

not if you are using JNI

[floral drum]

[quiet ice]

It will be painful in a few years though when you have to guess the version you wanted to compile it with

[wet breach]

https://tenor.com/view/mew-cat-kitten-kitty-cute-gif-17624380

[wet breach]

I get the feeling you been waiting this entire time to finally use that

[floral drum]

nah I use it often

[tardy delta]

heehee

[wet breach]

one of these days I am going to start a collection of stupid ideas derived from this discord XD

[floral drum]

pycharm!

[granite owl]

xD

[floral drum]

or whatever its called

[tardy delta]

atleast college is up to date and not using java 8 anymore

we are on 17 now

[floral drum]

woo 17

[tardy delta]

im actually on 19 but nobody cares

[quiet ice]

:( We are still on Java 14

[wet breach]

not like the concepts of java changed

[granite owl]

our prof said he doesnt care which jdk we use since we work with the basic features only that exist since java 9 or so

[floral drum]

we love virtual threads!!

[tardy delta]

we were using bluej in the first semester so its a good improvement

[granite owl]

so im using the jdk 20

🐒

[wet breach]

however, java 17 has unix sockets

so that is a plus to use that

[tardy delta]

some new syntax sugar :D

[quiet ice]

The biggest thing about modern java is that classloaders have names

[granite owl]

as long as java doesnt change like .NET 6+

where the main class and namespace are hidden

and make it look like u code in the global scope

[tardy delta]

java modules :)

[granite owl]

🤣

[tardy delta]

then realizing it fucks with your reflection

[quiet ice]

If you mean like in a huge breaking change; it probably will happen in the future

[granite owl]

;-;

[wet breach]

technically you do when you initially creating a java application given a true main class needs statics everywhere

[granite owl]

well i mean a plugin is ofc different to a java program

[quiet ice]

Project leyden might be fun for modders and valhalla might brick quite a few libs depending on how it is implemented and other things

[granite owl]

when ive written a plugin api in c++ for a different project i adapted bukkits mechanics

idk if that was so smart tho

plugins as .dll

[wet breach]

it wasn't

[granite owl]

xD

[wet breach]

there is a lot of things in bukkit that were designed purposely flawed

[granite owl]

yea i figured

[quiet ice]

Bukkit's event bus isn't that great I have to admit

[granite owl]

thats why i changed from a pure event driven system

to utilizing an entry point

[wet breach]

well event driven system is more ideal

[granite owl]

i mean i used both

[quiet ice]

isn't that still kinda like events?

[wet breach]

since most of everything is derived from player input whether directly or indirectly

[granite owl]

well i mean if u view a dlls entry point as onLoad

it could prob be seen as an event

but its more versatile

[wet breach]

well the only alternative that could work is a subscribing system

[tardy delta]

isnt that the bukkit way?

[granite owl]

i think

[paper venture]

is jump effect the only way to prevent player from jumping?

[wet breach]

no, bukkit is events and it will send out an event regardless of who is listening

[granite owl]

i did use events tho

i let the plugins notify the loader to add their function pointer to an array that was then being iterated

or remove their function pointer

to unregister the plugins event

[tardy delta]

in a subscription system, if you sent an event and there are no listeners, isnt the event discared too?

[quiet ice]

That sounds more like C than C++

[granite owl]

like i said i wrote a plugin system in c++

in which i adapted bukkits mechanics

on how to do things

[quiet ice]

Yes but using function pointers and storing them in arrays sounds very C.

[wet breach]

no, as long as the cancel isn't set, it will just continue. It isn't discarded just the server moves more quickly then before since nothing actively wanting to do something with that particular event

[granite owl]

i did iterate the array in assembly

im not gonna elaborate why tho

🤣

[tardy delta]

i have no idea what the dif is actually

[granite owl]

u cant iterate c++ objects in inline assembly

but u can iterate primitive C arrays by index

[tardy delta]

i did some array iterating stuff in my weird language thing

[granite owl]

so the overlaying system was c++ with a mix of c and assembly to iterate the registered events

[tardy delta]

its kinda weird tho

[granite owl]

whats that

[quaint mantle]

so what is the problem now the creation or the listener

[tardy delta]

wanted to make some kind of assembly/ bytecode looking like lang but i regret making the syntax look like that

[granite owl]

basically if u wanna iterate an arrays entires on byte level u do ```txt
(startingAddress + (index * sizeof(array data type)))

[tardy delta]

thats what i did

[quaint mantle]

another dumb quastion but how i can run a bukkit command in a async event ?

i tried

Bukkit.getScheduler().callSyncMethod(Mco.getPluign(),() -> p.getWorld().spawnEntity(p.getLocation(), EntityType.CAT));

and

new BukkitRunnable() {
            @Override
            public void run() {
                p.getWorld().spawnEntity(p.getLocation(),EntityType.CAT);              
            }
        };

but none of them worked

[tardy delta]

i only fucked up at the sizeof(type), it worked before but then i decided to change the impl and it didnt longer work :(

[hazy parrot]

Just runTask

[chrome beacon]

?scheduling

[tardy delta]

uh oh manually instantiating bukkitrunnables

[quaint mantle]

anyone know how i can find out of my barrel creation actually added the pdc

[tardy delta]

🩴

here it is

[hazy parrot]

Any nbt editor or trough code

[quaint mantle]

well whats the easiest way

[chrome beacon]

It would probably show up in the data command

[granite owl]

btw when did vanilla mc add the feature of adding a teams prefix and suffix

[chrome beacon]

A very long time ago

[opal juniper]

what isnt working

[granite owl]

no i mean via a vanilla team command

[chrome beacon]

ah 1.13 is the earliest I can find on the wiki

[opal juniper]

also it is better practice to store NamespaceKeys as like a static thing somewhere

[wet breach]

asm{
   loop1:
     mov ax, this->var
     ...
     dec ax
     cmp ax, 0
     je exit
     jmp loop1
}

[granite owl]

thats still along time ago xD

[wet breach]

nothing too hard there

[quaint mantle]

well nothing is really. the block does get created but my listener doesnt cast ig(onbreak). I dont know if the listener is wrong or the commannd doesnt add the pdc

[granite owl]

isnt the loop counter in the cx register?

🤔

iirc cx is both loop counter and return value

[opal juniper]

have you got the correct Barrel Also, does the stuff inside the instanceof run?

[granite owl]

whereas ax and bx are arithmetik and boolean logic

and dx is universal

[left depot]

How to add custom ID's to blocks, (Im working on a miner robot system) so that players can upgrade their miner robot lvl etc?

[chrome beacon]

You can make that namespcaed key a constant

It doesn't change

[opal juniper]

i said that

[quaint mantle]

nvm it got the pdc

[opal juniper]

is your listener running?

[granite owl]

also it should be cmp X, 0 and then jne loop1

[quaint mantle]

should yes

[wet breach]

are you sure?

[granite owl]

check if its 0

jump if not equal loop1

[wet breach]

why check if its 0?

[opal juniper]

also, is that config valid? You do a null check and that would cause nothing to happen

[wet breach]

we wouldn't be iterating if it was 0

[granite owl]

ur using a decrementing loop dont u?

[wet breach]

that isn't a decrementing loop

[granite owl]

dec ax decrements

[quaint mantle]

configs valid i use it everywhere else too. It shouldnt have anything to do with the listener itself i suppose cause it worked before i added the pdc part

[granite owl]

then compare ax to 0

[opal juniper]

ok show the whole event listening method please

[left depot]

I can work with ZYX ID's, but if i break the block and place it somewhere else, the ID will be changed and everything will be reseted inside

[undone axle]

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

[wet breach]

ah forgot I posted the decrementing one

[left depot]

so how should i do that?

[quaint mantle]

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

[granite owl]

so it should be cmp ax, 0 then jne loop1

[wet breach]

what I posted is correct

[granite owl]

also im pretty sure the loop counter is in cx

it is if ur using a 2.nd label u didnt show here

[wet breach]

cx can hold the counter

its not the only register that could

or can

[granite owl]

i swear it was such a pain in my ass when i started

and had a corrupted stack

cause i didnt know cx stores the return value

🤣

[wet breach]

EAX, EBX, ECX, EDX, ESI, and EDI these registers are safe to use without restoring them to original values

[granite owl]

depends xD

stolen bytes cough

[opal juniper]

This code is not very readable. Are you storing the contents of a storage object in a yml config though? That is a horrible idea if so

i would reccommend attaching a debugger

[wet breach]

no doesn't depends. C++ or C has no expectation that those registers will ever remain the same or should be reverted

however those are not the only registers you could use

just those are the guaranteed safe ones

[quaint mantle]

no its like a luckyblock you could say. its a config file and when you break the block it has a chance of dropping the things listed in the config

[granite owl]

funny to even find someone who digged trough assembly nowadays

[opal juniper]

ok. still, use a debugger

https://www.spigotmc.org/wiki/intellij-debug-your-plugin/

[granite owl]

a = 8bit, ax = 16, eax = architecture dependent right?

[wet breach]

its the ultimate final way to optimize 😉

[granite owl]

ya but despite minor tasks i would NEVER want to write higher programming concepts in it. like that guy who wrote this roller coaster park game xD

[wet breach]

EAX is 32bit

AX is 16bit

order from greatest to least, EAX, AH, AL, AX

[granite owl]

from chatgpt

[wet breach]

AH and AL are technically part of AX

[granite owl]

for 64bit register

[wet breach]

but you can split AX to get AH and AL

[granite owl]

In x64 assembly, registers are 64 bits wide, and they are denoted with a "R" followed by a number. Here are some examples of x64 registers:

RAX
RBX
RCX
RDX
RSI
RDI
RBP
RSP

R prefix

idk if gpt is right but i doubt its wrong with such a standard

[tardy delta]

64 bit counter kek

i asked it assembly and it told me weird stuff so idk

[wet breach]

just because a CPU has 64 bit instruction sets doesn't mean you have to only use 64bit instruction sets

it is better to use 32bit sets unless you need 64bit

[granite owl]

i want 2^256 gold in my game

🐒

i think thats the main reason why most mmos use copper silver gold for currencies tbh

xD

[tardy delta]

wait we are still using the x86 instruction set today right?

[granite owl]

depends

[wet breach]

yes

[tardy delta]

i clearly didnt learn 64 bit registers exxisted then

[granite owl]

on the target system u compile it for

the architecture

but just because u compile for 64bit it doesnt mean u everything must be 64bit

but for example pointers will be

[quaint mantle]

the server im using rn isnt a local host is it really that good that i should bother setting one up rn?

[tardy delta]

ok i was confusing things

[wet breach]

only if you need addressing greater then 2GB or 3GB

[granite owl]

^^

🤣

star chitizen

[tardy delta]

storing addresses in ints 🤓

thats what i did

[granite owl]

dont make fun of me

🤣

[wet breach]

64bit instruction sets and 32bit sets coexist together these days

[tardy delta]

but i was only allocating 64 bytes for my program so no problemos

[granite owl]

thats what i do to store my pointers on javas end

[wet breach]

so it is valid to still learn x86 but worth to also learn AMD_64

[granite owl]

i mean

[tardy delta]

and arm is another thing then

[granite owl]

theres hardly much difference between learning the difference between 16bit to 32bit

and 32 to 64

its just larger

[wet breach]

there is a big difference

[granite owl]

as in being able to address more memory etc?

larger numbers

etc etc

[tardy delta]

instruction encoding?

[wet breach]

while yes larger numbers, there is still major differences especially in how things are done

[granite owl]

or wdym

[tardy delta]

oh god dont tell me my brother is going with the vacuum cleaner through his ps3

man never heard of discharge

[granite owl]

did he wash it appropiately before

under the shower?

[tardy delta]

he cleaned it with water

[granite owl]

🐒

[tardy delta]

dont ask me what that dude is doing

[granite owl]

imean u can clean it with watee

[tardy delta]

controller was laying outside and in the meanwhile it rained 💀

[chrome beacon]

tbh I've done that on my PC before

[granite owl]

technically u can

🤣

[chrome beacon]

The PC is going strong after 10 years

[tardy delta]

brrrrr

[left depot]

Block block = event.getBlock();
block.setType(Material.AIR);
block.getWorld().dropItemNaturally(block.getLocation(), new ItemStack(Material.PURPUR_BLOCK, 1));
event.setCancelled(true);

how to add a custom name to this blockdrop?

[tardy delta]

my laptop is already slow asf and i only got it half a year

imma reinstall windows ig

[granite owl]

i did clean my old pc once with a vacuum cleaner, afterwards it had random bsod's due to i presume a static discharge from the cleaner to the hardware. lesson learned but i was just dumb and like 15 back then xD

[tardy delta]

lmao

i had a bsod when discord crashed

[granite owl]

now to even open my pc casing

[left depot]

#general

[granite owl]

i put it and hardware it and myself to the heading pipe

[tardy delta]

💀

[granite owl]

and put it on a esd protection mat

[left depot]

I want to give it a name when someone breaks the block, it will be called "Robot Miner"

[tardy delta]

oh man he removed the backside of it and is going though the ventilator with the vacuum cleaner

gotta make sure its clean 💀

[granite owl]

get the itemstack and rename it there?

[haughty storm]

How can I save the mobdata of an entity and spawn an entity with the same data?

[granite owl]

either u store each attribute or u try to serialize the entire thing

[wet breach]

the only way to ensure it doesn't over heat. There is some PS3 models that have a defect where they build up an abnormal amount of dust due to the duct not being very well designed

[left depot]

like in the itemstack?
So

ItemStack(Material.PURPUR_BLOCK, 1, setName("This"))

[haughty storm]

ok, thank you. Hoped there would be an easier way

[tardy delta]

no clue, he got it second hand so it wont be the best quality at least

[granite owl]

prob id get a reference first tho since u need to address it in multiple individual instructions

[tardy delta]

stop thinking in c++

🤓

[granite owl]

u could hack the maps or whatever it is to inject ur custom mob with its custom behavior but idk how

and thats hardly easier

but idk how mobs are stored exactly as that prob involves alot of nms too

[twilit roost]

Bullet extends Snowball
[NMS]

    int postDeathTicks = 0;
    @Override
    public void tick() {
        if (shotFrom == null) {
            super.tick();
        }else {
            double distanceTraveled = shotFrom.distanceTo(this.position());
            if (distanceTraveled >= maxDistance) {
                postDeathTicks++;
                this.setDeltaMovement(0,-1,0);

                if(postDeathTicks >= 50){
                    this.remove(RemovalReason.DISCARDED);
                }
            }else {
                super.tick();
            }
        }
    }

Im trying to achieve Bullet drop, but instead of it going down, it just starts teleporting around before removal

[granite owl]

because u set it by -1

u need to deltatime the movement

otherwise if it teleports randomly around then theres another problem idk there yet

[twilit roost]

how do I delta time it
and I thought -1 on Y would make it down

[granite owl]

by measuring the real world elapsed time and multiply that by the movement?

[quaint mantle]

can someone give me a quick example of how to run a bukkit method in a async event ? i tried everything but it just dosent work

Bukkit.getScheduler().runTaskAsynchronously(Mco.getPluign(), new Runnable(){
            @Override
            public void run() {
                p.getWorld().spawnEntity(p.getLocation(), EntityType.CAT);                
            }
        });

i wanna summon a mob on chat event

[tardy delta]

go back sync

with another scheduler call
