[outer wadi]

thanks

[noble lantern]

ofc

[ornate patio]

k

[ivory sleet]

the last parameter in any function can be a vararg (Java)

[dusk shell]

@noble lantern plss

[noble lantern]

If none of those options work, then HorseAPI seems to just be broken asf and you may need reflections

or

[ornate patio]

nope, instantly adult

[noble lantern]

Interact event

-> Cancel it

-> add health manually

-> remove 1 from players in hand item

-> and play breed particles (if applicable for that item)

Thats probably easiest way now since all that shiz doesnt want to work

[ornate patio]

damn

[noble lantern]

sorry himme a sec

[ornate patio]

ugh

[dusk shell]

this

[ornate patio]

okay wait

i looked at the NBT data of a freshly spawned baby horse

i found this

lemme try that

[worldly ice]

yeah thats what i was looking at

doing /summon with a negative age value summons a baby horse

[ornate patio]

-1 didn't work though

maybe it has to be a specific negative value?

[worldly ice]

the horse is age locked right?

[ornate patio]

yes

[worldly ice]

yeah idk why that wouldn't work

[ornate patio]

age lock doesnt work for hand feeding though

[ornate patio]

anyways setting the age to -24000 actually worked

thank god

[green prism]

Player chat event isn't cancelled for the entire server spigot, so others plug-in can use the same one everytime. Help?

[compact haven]

cancelling a chat packet still passes it to other plugins

[echo basalt]

uhh pretty sure cancelling packets doesn't

[compact haven]

meaning logging plugins will still log it, etc

ah wait

I'm stupid

yes if you cancel the incoming packet

why was I thinking of outgoing

kek

I mean.. what's the goal

we need more info to tell you what's best

using the API is probably the best minus a few circumstances

the API lol

unless the goal is to prevent any part of the server from even knowing that a player chatted, then use the API

otherwise, the only way is to add a handler into the netty pipeline & don't let it pass

[ancient plank]

as a wise man once said: if it exists in the api, you should use it.

[quiet ice]

Unless the API is trash, the lessr wise man said

[compact haven]

just ignore the API & write directly into NMS 😏

[echo basalt]

That's exactly what I do lmao

I can't bother doing 20 jumps through the API if I can just call a specific field

[compact haven]

what

I'm talking about cloning NMS source into your IDE & coding onto it instead of using spigot

[echo basalt]

Ahhhhhhh

[compact haven]

not using reflection to call a method or get a field

[echo basalt]

Ehh

Current job has a spigot fork so I just add whatever I need into it

[ornate patio]

what color do you guys think i should make the age

[noble lantern]

That colors fine imo

Huh thats actually cool asf

Okay you should make a mobile app for it for shits and giggles

[mortal hare]

today it was my first day i've used yield in switch expressions

[noble lantern]

the fuck

is yield?

[river oracle]

wtf is yield

I've used it in python

[mortal hare]

java 16

[river oracle]

but I forgor

[noble lantern]

time to google

brb

[mortal hare]

lambda switch expressions

it basically like a return

but for switch expressions

[noble lantern]

omg thats badass

earlier today i did some stupid code as a joke

and its actually a real thing

LMAO

lemme find it

[mortal hare]

return switch(type) {
  case TYPE.FOO -> {
    if (this and not that) {
      yield true;
    }
    yield false;
  }
}

ofc with more cases and more complicated checks

[ornate patio]

hell no

[noble lantern]

It was actually real all along

just instead of if use else

thats funny af

[opal juniper]

that works no? what do you want to change

[severe turret]

tfw you swap to maven to not have to deal with shadowjar, and now your maven refuses to import mongodb

[noble lantern]

I was meming in general earlier just posting code that looks weird and wouldnt work xD

Hence why i was suprised when i saw yield, cause i was like oh they actually have that haha

[dull goblet]

Hey could anyone help me? I want to write a plugin for a leveling system for each player. Player will have different skills which each will have a level. How would I store this data? I was thinking reading and writing to a json file which will work and saving it every five minutes and keeping the Arraylist with playerlevel objects in memory. But won't this eventually take up too much resources since this object will become so large?

[lost matrix]

IO should be done async so it doesnt really matter if you need 0.5ms or 5ms to read/write files.
Files are decent if you only need the data to exist on one server. It it needs to be shared between several
instances then you need to use a Database.

There is a general approach to data lifecycles. Let me explain a bit more.

[mortal hare]

have you heard ternary operator

[noble lantern]

Yes but i didnt use it just to make people more mad

[mortal hare]

String string = that == this ? "this" : "that";

oh

you've just earned another hater then

i love ternary operator

[noble lantern]

Hate it

xD

That shit makes dyslexic people shiver in theyre boots

im trying to figure out wether b is d or if d is b and you over here like ?? :: ;; ?? ::

xD

[grand glade]

Sometimes it’s more comfortable to use it because that could shorten the code a bit

[lost matrix]

1. Data exists in 2 states: Live and persisted. Or in other terms: In memory or on disk.
2. Data has scopes. Usually you would differentiate between application scope and session scope.
   This defines when data should be loaded from disk into memory.
   Application scoped data is loaded when the application starts and saved when the application stops.
   Session scoped data is loaded when a session starts and saved when a session stops.
   Now we just need to define a "session" in minecraft terms:
   A session of a player usually starts when he connects to the server and stops when he quits.
   The same goes for chunks for example. A chunks session starts when the chunk is loaded and stops when the chunk is unloaded again.

Let me explain how to approach player sessions....

[mortal hare]

i use ternary operator almost every day.

i just dont nest them

[noble lantern]

boolean hah = otherTernary == true ? anotherTernary : null;

[dull goblet]

This is interesting, thanks for explaining 🙂 I'm listening 🙂

[noble lantern]

Data handling is a lot like baton running ngl

Hand baton to one person, baton is held by him for a bit, and eventually it comes back around

xD

[humble tulip]

Hm since you're talk abt data, what should I do if a player is online on one server and an admin tries to modify something about said player from another server?

Like whwre inventories are synced across a group of servers like skyblock

[noble lantern]

I typically:

Project startup:

1. Keep data and only edit the cached values for said player (Typically you have a HashMap<UUID, PlayerDataClass>) inside of a DataManager class that handles all this loading/saving

2. Have singleton timer that runs async every x minutes, where it loops through the values of that map, and writes them to file (use the async bukkit timer)

Player join:

1. Load data on async player join event, make sure to execute a blocking get no async or else the player logs in before data is loaded (This is the only non-async operation you should do, is the GET in an async player join)

2. On player disconnect, write they're cache to file and remove from cache, repeat

Basically what smile was saying but simpled down to minecraft terms

This is just something basic, you can get more complex the more requirements you need, like with smile said when you need data synced between servers, or servers need to share data

[humble tulip]

Problem i had with loading on async join is of players switch servers, it starts loading their daya before it saves on the prev server

[noble lantern]

Shouldnt really be an issue imo

just throw his data away it he switches servers

its no longer needed, hes not there and he didnt do anything to effect his data if he just instantly switched

Besides the player cant leav in async player join anyways

the cancel button isnt there, so youll have to alt f4, or modded clients

[humble tulip]

Noo

If a player quits after playing

[noble lantern]

Theres a bunch of Statistic issues for spigot ide just handle them myself at this point ngl

Like BREAK_BLOCk statistic not working if the item doesnt drop an item (BlockBreakEvent#setDropsItems(false))

Yep

If you setDropsItems false on BlockBreakEvent the BREAK_BLOCK statistic breaks and wont increase

I reported it on spigot, doc opened a PR but no new news on it yet

ohhh i see

[humble tulip]

So?

[noble lantern]

This shouldnt be an issue either

[lost matrix]

First we need to define our data class.

@Data
public class PlayerData {
  private long firstLogin;
  private ClanUserData clanUserData;
  private JobData jobData;
}

@Data just generates getter, setter, toString, equals and hashCode methods.

Next we define an Interface which has the task to save/load this data. The implementation can be done with Files or whatever.

public interface PlayerPersistenceHandler {
  CompletableFuture<PlayerData> loadDataAsync(UUID playerId);
  void saveDataAsync(UUID playerId, PlayerData playerData);
}

Dont be scared by the CompletableFuture. You can simplify this if you want.
Next we define our manager class that holds the live player data. This is our single entry point for interacting with player data.

@RequiredArgsConstructor
public class PlayerDataManager {

  private final Map<UUID, PlayerData> playerDataMap = new HashMap<>();
  private final PlayerPersistenceHandler playerPersistenceHandler;

  public void loadPlayerData(UUID playerId) {
    PlayerData loadedData = playerPersistenceHandler.loadDataAsync(playerId).join();
    playerDataMap.put(playerId, loadedData);
  }

  public void unloadPlayerData(UUID playerId) {
    PlayerData liveData = playerDataMap.remove(playerId);
    if(liveData == null) {
      return;
    }
    playerPersistenceHandler.saveDataAsync(playerId, liveData);
  }

  public PlayerData getPlayerData(UUID playerId) {
    return playerDataMap.get(playerId);
  }

}

At last we are defining our listener. This couples the data with a players session:

@RequiredArgsConstructor
public class PlayerDataListener implements Listener {

  private final PlayerDataManager playerDataManager;

  @EventHandler
  public void onAsyncLogin(AsyncPlayerPreLoginEvent event) {
    playerDataManager.loadPlayerData(event.getUniqueId());
  }

  @EventHandler
  public void onQuit(PlayerQuitEvent event) {
    playerDataManager.unloadPlayerData(event.getPlayer().getUniqueId());
  }

}

[noble lantern]

the player left, save theyre data?

[smoky oak]

is there a spigot mixin tutorial somewhere thats not restricted to the october twenty fifteen version of the game

[noble lantern]

Ayo can we pin this fr

Didnt expect you to go into full code example damn, save it so you dont have to retype it xD

[humble tulip]

Ok

[noble lantern]

Ide just use a Lib or PDT tbh

[humble tulip]

Player quits at 4503ms

Data is saved async at 4527ms

[noble lantern]

Oh i see and by the time the player joins the data isnt saved remotely?

[humble tulip]

Yes

[noble lantern]

For that youll need to mark the servers data state as saving with redis

[smoky oak]

*twenty seventeen

[noble lantern]

and when you receive the callback of completion, mark them as completed in redis

[humble tulip]

Asyncplayerpreloginevent happens really early

[lost matrix]

An example usage would look like this:

public final class SpigotSandbox extends JavaPlugin implements Listener {

  private PlayerDataManager playerDataManager;
  private PlayerPersistenceHandler playerPersistenceHandler;

  @Override
  public void onEnable() {
    this.playerPersistenceHandler = new PlayerFilePersistenceHandler();
    this.playerDataManager = new PlayerDataManager(playerPersistenceHandler);
    PlayerDataListener playerDataListener = new PlayerDataListener(playerDataManager);
    Bukkit.getPluginManager().registerEvents(playerDataListener, this);
  }

}

If you need the player data anywhere, then all you have to do is pass the PlayerDataManager instance there.

[noble lantern]

Theres no real reason to re-invent the wheel

and no

Thats why i reccomended a lib...

Like NBTAPI

It uses reflection

[worldly ingot]

Or Bukkit API

[lost matrix]

*However this is a bit dangerous because if your server crashes, then your data will not be saved.
Thats why it it common practice to regularly persist the entire cache every few minuts.

[worldly ingot]

PDC has existed since 1.14

[noble lantern]

^^^^^

PDC is godsend

Youll be reinventing the wheel with nbt unless your using remapped jar

[worldly ingot]

1.13 had another implementation you could use as well

Though I'd avoid it

[lost matrix]

Yes of cource. If you want to write custom data into NBT then just use a pdc

[worldly ingot]

Welp

[ornate patio]

bump

[noble lantern]

NBTAPI it is

[lost matrix]

well...

[noble lantern]

https://www.spigotmc.org/resources/nbt-api.7939/

supports more than just nbt tags too

[dull goblet]

Thank you very much for your time @lost matrix i'll deffo look into this 🙂 Don't fully understand everything but time to learn!

He is isn't he

[noble lantern]

it remaps all the bullshit d a b obfuscated names for you via reflection in this lib so you dont have to do it via NBT and suffer

[lost matrix]

Def. This is also important to understand if you want to stay in the industry.
Because basically everything is just CRUD

[smoky oak]

does anyone know this by chance?

[mortal hare]

technically as a storage format no, but in order to manipulate NBT data in minecraft you'll require NMS

[noble lantern]

You can use reflection

NBT-API has no nms import, only reflection

[mortal hare]

just check the slot

if the item is static and cannot be moved

[dull goblet]

I'm used to using sql/mysql json, so this is a bit different

[mortal hare]

then check the slot index

[noble lantern]

[mortal hare]

items would be unmovable

so the slot indexes wouldnt change

[noble lantern]

nbtapi

[quaint mantle]

Hey, if i set the persistent data of a player, would it persist after login and logouts, and server restarts?

[mortal hare]

for these items

[lost matrix]

This can be applied to any persistence method. yml, json, SQL, MongoDB. You name it.

Just implement the PlayerDataPersistenceHandler

[vagrant stratus]

https://tenor.com/view/betty-white-golden-girls-hands-gif-24420157

[noble lantern]

no way thats betty white hitting the dab

[quaint mantle]

uhh

[noble lantern]

idk how i feel about this, thats something new

[mortal hare]

checking index is way computationally faster than lets say a string or some kind of collection which does not provide O(1) random access

[quaint mantle]

I just need an answer really quick

[noble lantern]

Considering the name Persistant, i assume so

[vagrant stratus]

https://tenor.com/view/bill-gates-dab-gatesdab-billgatesdab-gif-12977596

[noble lantern]

meta data is stuff that will never save-

BRO WTF

BILL GATES HITTING THE DAB 2022 circa (colorized) 🥵 🥵 🥵 🥵

he looks like hes trying to make an F though, not a dab

he didnt bend his front arm

[dull goblet]

how would the saveDataAsync method be with json? Don't you have to rewrite the whole file in json? In sql you can just choose a record id right? Or do you store a file per player?

[lost matrix]

Do you still have my 2 classes for the BlockFinder?

[lost matrix]

One moment

[noble lantern]

Json you basically just overwrite the data in said file

[mortal hare]

    @Override
    public int getSize() {
        return 5;
    }

[noble lantern]

And have a file for each player

[mortal hare]

player's inventory menu

returns 5

[noble lantern]

and the name of the file is theyre UUID

[mortal hare]

of its size

[ornate patio]

uhh not really

i can search for it real fast

[mortal hare]

https://tenor.com/view/wtf-is-that-confused-gif-14675917

[noble lantern]

Look at the essentials userdata folder, they do it like how i said on there 🙂

[ornate patio]

found the message link

#help-development message

[noble lantern]

Can see a perfect example for saving your data there (Unles your wanting to split it up even further, essentials just shoves all the player data in the one file which may not be ideal if you wanna catagorize the data)

[dull goblet]

Okay thank you for the help you guys!

When should you use YAML to store data or when JSON or does it not matter

[noble lantern]

IMO i would never use YAML for storage, mostly everyone else will say the same

YAML for configs only

JSON read/write and parse is faster than YAML too, not a lot that its gonna make a worlds a difference, buts still faster

[severe turret]

Anyone has any idea why my maven doesn't want to import mongodb 😆

[humble tulip]

Send ur pom

[lost matrix]

?paste

[undone axle]

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

[lost matrix]

This is a trivial implementation for PlayerPersistenceHandler
https://paste.md-5.net/ipehixamic.java

It uses Gson as the bridge from live object to json

[noble lantern]

Wait what the

That class is built into spigot?

[dull goblet]

Is CompletableFuture a bit comparable with a task in C#

[noble lantern]

How is it used? Is there some type of handler/dispatcher like the commands/events?

[dull goblet]

This look awesome thanks

[lost matrix]

More with a delegate

Wait

No Task

yes Task is a good comparison

[severe turret]

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

[lost matrix]

Nope this is just something ive come up with

[lost matrix]

You shouldnt shade in jetbrains annotations

[noble lantern]

Ahh okay, the name made it seem like it was made by spigot ahaha 🤣 was about to say dang ive done it wrong the whole time making my own system

[severe turret]

how do i exclude it

[humble tulip]

scope provided

[lost matrix]

<scope>provided</scope>

[severe turret]

ah I see

and do you know why my mongo import doesnt work

[lost matrix]

The dependency looks good. Should work.

[severe turret]

Well it doesn't

oh well

guess I have to learn shadowjar

[noble lantern]

Did you reload maven

[severe turret]

I rebuilt

reloaded all projects

tried different mongo versions

nothing

I can import it on gradle

but I don't know how shadowjar works

[noble lantern]

implementation?

shades it right in for me

unless your needing some fancy shiz

[severe turret]

wdym

I have no idea how to use it so

[noble lantern]

?paste

[undone axle]

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

[noble lantern]

sec

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

This is my gradle for another project, works fine as is

Compiles fine and runs fine with all libs

[severe turret]

yeah but that's not spigot

[noble lantern]

Ive never needed to use shadowJar unless im wanting like to exclude stuff im not compiling in or whatnot, similar to maven

[severe turret]

I need it to run from the plugin jar

[lost matrix]

https://gist.github.com/Flo0/23a00897a7c73e34a5eccbc702afc7e9
Try this out. Do like 10 steps per tick.

[severe turret]

if i just compile it into a jar i get classnotfound exception

[noble lantern]

What was your old gradle file

[lost matrix]

How do you compile?

[noble lantern]

send it

[severe turret]

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

idk why it shows ruby lol

[ornate patio]

oh sheesh thanks

i'll check it out after i finish this

[lost matrix]

How do you compile the plugin?

[severe turret]

I just click run

and it compiles into .jar

[noble lantern]

you need to run shadowJar task

not the basic build one

[severe turret]

how

[lost matrix]

Isnt he using maven?

[noble lantern]

should show up in the list when you make it

[severe turret]

I swapped my project from gradle to maven

[noble lantern]

For his gradle file he sent im talking about

[severe turret]

because I didn't want to deal shading

but maven doesn't want to import mongodb for some reason

[lost matrix]

Maven has the maven-shade-plugin and gradle has the shadowJar plugin. You need to deal with them either way.
I personally find maven much simpler when it comes to shading.

[severe turret]

yeah

[noble lantern]

yeah mavens definatly one click and go

[humble tulip]

Did u invalidate caches and restart?

[noble lantern]

^

not bad idea

[severe turret]

how

[noble lantern]

top left

in the File tab

its near the bottomish

[humble tulip]

More middle bottom

Iirc

[hidden kestrel]

In my custom chunkgenerator, how woulld I go about making the entire world Plains?

[severe turret]

nope

doesn't work

only thing that gets imported is the bson

other stuff doesn't

that's why it's so weird

[noble lantern]

wait send the maven file again

Or whichever you were just building with that just did that

[severe turret]

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

[noble lantern]

Weird its on maven central to hm

[severe turret]

how do I use the shadowjar

[noble lantern]

When you create the task should just be a button like this one

[lost matrix]

Implement ChunkGenerator and implement the generateNoise(WorldInfo worldInfo, Random random, int chunkX, int chunkZ, ChunkData chunkData) method

[noble lantern]

The actual shadowJar task seems simple though ive never made one

here sec

shadowJar {
    archiveBaseName.set('yourarchivename')
}

IIRC it needs the baseName as a minimum

[lost matrix]

Just let another task depend on shadowJar. This way you also have a one click solution

[noble lantern]

That too ^

[hidden kestrel]

I am

But it seems that BiomeGrid is deprecated

[severe turret]

what do you mean by archive

[noble lantern]

jar name essentially

archive is just another word for jar in a sense, the finished product

you can also

[severe turret]

do i put that at the end of my build

[chrome beacon]

Didn't you switch to maven?

[noble lantern]

not sure about that part ngl, i know gradle is bitchy sometimes about that

[chrome beacon]

Or did you switch from maven

[lost matrix]

One moment let me take a look. Didnt work with that for a while.

[severe turret]

I switched from gradle to maven because I didn't want to meddle with shading

[noble lantern]

On this project its near the middle so i guess it doesnt matter where the task goes, just needs to be in global scope (Not nested in anything unless somethings depending on it like smile said)

[severe turret]

and then I found out my maven doesn't import mongodb

for some reason

so I have to use shadowjar

[noble lantern]

Olivo when profile picture 😦

[vital ridge]

Whats up. What would be the best way to load a chunk before player teleports there? I'm creating a random tp plugin and I don't want the player hovering in the void for 3 seconds when teleporting cuz the chunks are loading.

[humble tulip]

Ur chunks take 3 seconds to load 👀

[dull goblet]

Hey is it normal that pdc doesn't go between two plugins?

[chrome beacon]

When people stop asking for it

[humble tulip]

Because each plug uses its own namespace

[noble lantern]

Can you explain a lil more?

[humble tulip]

That's why namespacedkey take your plugin

[noble lantern]

Its because its new chunks

[humble tulip]

Ah

[noble lantern]

You need to call generate first and then tp him

[humble tulip]

Makes more sense

[severe turret]

https://paste.md-5.net/cizukoxaje.rb so like this?

[noble lantern]

you can call generate on existing chunks iirc, it should harm it unless your using the force setting

[dull goblet]

Wait so if I reference the plugin i want to share it between in the namespacedkey it'll work?

[severe turret]

oh!

[noble lantern]

Yeah thattl do

You can create a static instant for both plugins

[severe turret]

now my gradle has

shadow in tasks

is that good?

[noble lantern]

have one soft depends on it and use ThatMainClass.INSTANCE from both plugins, relativly easy for that part

[dull goblet]

won't it need to hard depend?

[noble lantern]

either or

prolly yes hard depend

since your gonna be directly using it and its essential for both to be running

[hidden kestrel]

Brilliant

[dull goblet]

It's because i'm making an economy system but with physical currency instead of virtual

[vital ridge]

Which class provides that method?

[severe turret]

think it's working now

[dull goblet]

So i want to make sure the currency is unique

[noble lantern]

Ahh i see then yeah definatly hard depend both plugins

[noble lantern]

Chunk should or its in Location

99% sure its Chunk

1% is my insecurities

[vital ridge]

Neither of those has it.

[noble lantern]

ohhh fuck

sec

[vital ridge]

World has regenerateChunk

[noble lantern]

ahh i think

its load(true) but

i need to check docs

2 mins

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Chunk.html#load(boolean)

aha

yes

[vital ridge]

but that didnt work, iirc someone said in the forums that if there are no players in radius it gets unloaded again.

Anyways I tried it and it didn't work.

[noble lantern]

Yes but its taking so long because they need to generate

[dull goblet]

Would a bukkitrunnable be a good way to store the data every 5 minutes?

[noble lantern]

Hence why you hover for a few secs

[noble lantern]

Yessir just make sure its async runnable

[vital ridge]

So you think I should delay my teleport more?

so loadChunk

and then wait like 5 sec

Currently I'm waiting 3 sec

[noble lantern]

You could do that yes, or call the load() first, and then setForceLoaded(true) (https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Chunk.html#setForceLoaded(boolean)) KEEP TRACK OF THIS CHUNK!!!!!!!!!!!! This method is dangerous!!

then you can tp him

[smoky oak]

i find that my server can generate and send to a client about thirty chunks per second. I'm unsure if the cpu or the connection is the throttle though. You should be fine waiting three seconds i guess

[noble lantern]

The method is dangerous because if you load shitloads of chunks, those chunks wont clear out

[vital ridge]

Mhm gotchu, I'll make sure the setforceloaded back to false

after tping him

[noble lantern]

Yeah 3 seconds for a rtp is 100% resonably plus you can add fancy effects too

[noble lantern]

Yep thats the best way

Just dont use it when searching for a safe location

thats the main issue when using it

[smoky oak]

cough accidental dos cough

[noble lantern]

(I learned that the hard way)

[vital ridge]

But should I only load 1 chunk?

[humble tulip]

Yes

[noble lantern]

You could load around yes

But the one is fine

[humble tulip]

One is fine no?

[noble lantern]

Yes one is fine, i had nicer effects loading a 3x3 when i made mine though

just better TPS performance overall somehow

but one was still fine

[vital ridge]

How does it work tho? If you load just one the others will load faster and easier?

the others around the one you just loaded

[noble lantern]

i loaded the 3x3 before the player TPd

i used a CompletableFuture and called all those methods for the chunks effected

[humble tulip]

They won't be in the void

[severe turret]

oh my god

[humble tulip]

The rest will load around them

[severe turret]

it finally works

[noble lantern]

and in the callback, i teleported the player on future completion

[severe turret]

thank you :D

god bless gradle

[humble tulip]

Chunks can be loaded async!?

[noble lantern]

nonononoon

it was a sync future

you can run them on main thread

[humble tulip]

Uhh then why use a future?

[noble lantern]

Just easier because you get the callback from the future

so you can easier see the flow of whats executing

[smoky oak]

... 💡
I'm going to make a plugin that loads chunks in front of you if you move exactly north, south, east, or west, and snaps boats on blue ice to cardinal directions

nether highways will work so much better

[noble lantern]

IE like this

So loadChunksAroundLoc(loc).thenAccept((listOfChunks) -> { // teleport, chunks are all loaded and ready for us to use });

[severe turret]

How do I stop NotNull from shadowing in gradle

[noble lantern]

Like just highways of ice?

[severe turret]

compileOnly?

[lost matrix]

This is what i got so far:
A generator that generates a square world and afterwards only a bedrock ocean

[smoky oak]

yes, those things are fast. Servers tend to lag out when travelling at high speeds, with blue ice and elytras specifically

im more doing this because of elytra than boats

[hidden kestrel]

I'm trying to make it a terrain though

[smoky oak]

if the chunks arent loaded you get rubberbanded

[hidden kestrel]

This is what I have so far

[smoky oak]

and thats bloody annoying

[noble lantern]

havent messed with blue ice yet ill need to take a look

[smoky oak]

*the chunks you travel through

[hidden kestrel]

public class TerrainGenerator extends ChunkGenerator {
    
    
    private boolean generateStuff;
    
    public TerrainGenerator() {
        generateStuff = true;
    }
    
    @Override
    public void generateNoise(WorldInfo worldInfo, Random random, int chunkX, int chunkZ, ChunkData chunkData) {
        if(chunkX < 2 && chunkZ < 2 && chunkX > -2 && chunkZ > -2) {
            generateStuff = true;
            return;
        } else generateStuff = true;
        for(int y = chunkData.getMinHeight(); y < 61 && y < chunkData.getMaxHeight(); y++) {
            for(int x = 0; x < 16; x++) {
                for(int z = 0; z < 16; z++) {
                    chunkData.setBlock(x, y, z, Material.BEDROCK);
                    chunkData.setBlock(x, y + 1, z, Material.WATER);
                    chunkData.setBlock(x, y + 2, z, Material.WATER);
                }
            }
        }
    }
    
    @Override
    public boolean shouldGenerateNoise() {
        return generateStuff;
    }
    
    @Override
    public boolean shouldGenerateBedrock() {
        return generateStuff;
    }
    
    @Override
    public boolean shouldGenerateSurface() {
        return generateStuff;
    }
}

and I'm trying to make it only generate plains biomes, because an ocean biome .. surrounded by water .. is dumb

Also if you could let me know if I've done it in a super inefficient way or if this is fine

This is the first time I'm really digging into worldgen

[smoky oak]

you can set the biome but that wont change the blocks there

[hidden kestrel]

Crap

So I can't force it to only generate plains??

[noble lantern]

it will change grass block looks tho

nah not that sadly

all thats on you to do

world gens are pretty complex ngl

people who make those are a different breed

they scare me

[smoky oak]

maybe steal the nms code for flatland generation

and give it the plains biome

[noble lantern]

superflat should be easy to generate

its just generating blocks at a set y axis infinitely

[smoky oak]

actually if you use the plains preset it generates trees, flowers, and small ponds

[dull goblet]

public void saveAllPlayerData() {
        for (Map.Entry<UUID,PlayerData> data :
                playerDataMap.entrySet()) {
            if(data == null) {
                continue;
            }
            playerPersistenceHandler.saveDataAsync(data.getKey(), data.getValue());
        }
    } 

Would this be good to put them all in a different operation or should happen in one async method instead of another per player

[noble lantern]

Ohhhh

[smoky oak]

youre thinking about the normal superflat

[noble lantern]

I mean tbf

generating trees wouldnt be too hard

flowers maybe

[smoky oak]

eh the one time i tried generation i got a diagonal line of blocks

[noble lantern]

just bc theres so many

[smoky oak]

while trying to do a random distributino

so

eh

[noble lantern]

hahaha xD

well you do a chance per block

[hidden kestrel]

I mean so I guess I should just do custom terrain then right

[lost matrix]

This is kind of ok. But data is never null

[smoky oak]

was a structure actually

[noble lantern]

Ohhh

structures littlle more complex bc they can go outside the chunk 😠

[smoky oak]

every chunk whose added x and z coord was a specific number generated that

i made sure to contain them in the chunk

not too big

[noble lantern]

ahh

okay thats good

[smoky oak]

but still weird that going north and east sixteen blocks gives you another copy

as said

supposed to be random

[dull goblet]

Okay thanks

[smoky oak]

i need to take a look at how math random seeds and massive numbers interact

cuz i bit shifted the z value by ten i believe then added the x value

[noble lantern]

yeah fuck this

im out

thats beyond anything i could ever do LMAO

[smoky oak]

hey a vertical ocean

aaand thats where i leave

[lost matrix]

Btw why dont you just have a void outside the generated chunks?

[vital ridge]

Sht well 1.8.8 doesnt have that method

So if I just load the chunk it gets unloaded pretty quick

I assume

[noble lantern]

NMS maybe

[vital ridge]

CUz when I get there I'm still in the void

[noble lantern]

or reflection

Might be able to access that method that way

Dont exactly have time to run through something like that rn haha

[lost matrix]

Let me check. Wasnt there an article on how to handle nms block placement?

https://www.spigotmc.org/threads/methods-for-changing-massive-amount-of-blocks-up-to-14m-blocks-s.395868/

Ok lets see what we can optimize here

[vital ridge]

what about setSaveChunk in chunkUnloadEvent

it saves the chunk on disk

what does that mean?

[dull goblet]

@lost matrix i put my project on github and wanna credit you how do you want me to do it? Like what name or something

[hidden kestrel]

https://i.imgur.com/7UBipfb.png

This is what I have

using the code I posted earlier

[hidden kestrel]

That would be significantly easier lol

but I'm trying to make it like in 0.30

[lost matrix]

First of all:

            if (blocks.containsKey(chunkKey)) {
                blocks.get(chunkKey).add(new NMSBlock(pos, blockData));
            } else {
                final List<NMSBlock> value = new ArrayList<>();

                value.add(new NMSBlock(pos, blockData));

                blocks.put(chunkKey, value);
            }

Should be

blocks.computeIfAbsent(chunkKey, key -> new ArrayList<>()).add(new NMSBlock(pos, blockData));

It does the same just with some fewer cpu cycles.

This one

[lost matrix]

7smile7
But you dont need to

Then this:

final Chunk nmsChunk = ((CraftChunk) this.world.getChunkAt(new Location(this.world, pos.getX(), pos.getY(), pos.getZ()))).getHandle();

Can be improved:

final Chunk nmsChunk = ((CraftChunk) this.world.getChunkAt(pos.getX() << 4, pos.getZ() << 4)).getHandle();`

Dont see any other low hanging fruits there

Yeah caching the chunks might be a good idea. Not super important tho.

[lost matrix]

I mean this looks fine, no?

[hidden kestrel]

I think so

Except I seem to have some random problem going on here lol
https://cdn.discordapp.com/attachments/981614238885892138/991107679185547354/unknown.png

[lost matrix]

With a

Map<Long, Chunk>
And computeIfAbsend

Or you can group the locations by their chunk id (long)

None of those are worth doing

Chunks are cached internally anyways.

So after the first getChunkAt() call it doesnt really matter

You will only play for micros at that point

It would be async. So you would have to completely re-write your method

And it would be a lot more complicated

[noble lantern]

CompletableFuture isnt too complicated tbh

getChunkAtAsync().thenAccept((theChunk) -> {
    // do your SYNC stuff here, main thread here!!
});

[lost matrix]

Does it need to be a bulk method? Because getChunkAtAsync() might spread the placement over
several ticks

[noble lantern]

Doesnt Future have a way to execute multiple futures at once?

I know javascripts Promises do

CompletableFuture.allOf(. . .)

[lost matrix]

Well... then going for nms stuff is pretty useless. You can easily place hundreds of thousands of blocks
in one seconds with the spigot method by simply spreading it over 20 ticks

[noble lantern]

ouah

fawe doesnt even do that in a second i dont think haha

maybe 5-10 seconds

[lost matrix]

Well. Whats wrong with using fawe?

[noble lantern]

^ faweapi

You can use the normal world edit api with fawe iirc

[hybrid spoke]

edit the file manually

[lost matrix]

I can do probably billions per seconds if you give me a good CPU and an NVMe with enough PCIe lanes.
Ill just pump out a gazillion region files with only stone in them.

[noble lantern]

copy paste the same file over and over

boom

[ornate patio]

@lost matrix i've implemented the code you sent me to the best of my ability but I don't really see anything happen

I'm stepping it 10 times per tick like you said

[lost matrix]

Oh yeah. There is quite a bit more you have to do.
So all this code does is find a suitable block in your surroundings.
You still need to add a simple pathfinder goal and let the entity wander to that block.
(When one is found)

[ornate patio]

public class BlockFinderTask implements LoopingTask<SuperiorHorse> {
    @Override
    public int getIntervalTicks() {
        return 1;
    }

    @Override
    public void runLoopingTask(SuperiorHorse superiorHorse) {
        for (int i = 0; i < 10; i++) {
            superiorHorse.getBlockFinder().step();
        }
    }
}

LoopingTask is an interface that I've created (i'm 100% sure it works i use it everywhere)

[ornate patio]

so how would i get the block that it's targetting though

[lost matrix]

Just use the nms pathfinder goal

[lost matrix]

Also this task should be inside the SuperiorHorse tick method (Im assuming SuperiorHorse extends the NMS horse)

[hidden kestrel]

public class TerrainGenerator extends ChunkGenerator {
    
    
    private boolean generateStuff;

[ornate patio]

SuperiorHorse is more of a wrapper which contains the nms Horse and bukkit Horse

with a bunch of other util functions

[lost matrix]

Uhm... thats a super weird approach because the bukkit horse already wraps the nms horse

[ornate patio]

i know its weird but i have a reason

i first tried to do everything within the nms horse

but it caused spigot to desync with nms

[lost matrix]

[ornate patio]

for example if i set the horse armor with nms, and then tried to get the horse armor using spigot

spigot would say there is none

so I basically try to do everything on the bukkit entity, but if I can't then i resort to the NMS entity (such as for pathfinding)

[lost matrix]

public class CoolHorse extends Horse {
  public CoolHorse(EntityType<? extends Horse> var0, Level var1) {
    super(var0, var1);
  }

  public void setArmorThroughBukkit(ItemStack armor) {
    ((CraftHorse) this.getBukkitEntity()).getInventory().setArmor(armor);
  }

}

[ornate patio]

oh

lmao damn

[lost matrix]

NMS Horse with bukkit bridge for the armor

[ornate patio]

well too late i already built like my entire plugin based on this system

[lost matrix]

big oof. How do you even keep track of the horses when they are being unloaded then?

[ornate patio]

like, save their data?

what do you mean keep track

[lost matrix]

If a horse gets unloaded with a chunk and loaded again later, how do you persist the data?

[ornate patio]

Any changes I make to the SuperiorHorse will automatically update the persistent data container of the horse

[lost matrix]

I see

Thats expensive

[ornate patio]

so that if the server restarts, it basically kills the original horse and replaces it with a new version of the NMS horse

[lost matrix]

Do you extend the nms horse at all?

[ornate patio]

yes

i have a SuperiorHorseEntity which extends the nms horse

which is contained within SuperiorHorse

[pallid forge]

very quick question, how do you get a world? I want to set a gamerule, and i think i need the world to do that.

[iron glade]

Can someone help me with my english? How would you call it when a player is in lava or water? Player is in liquid? xd

[lost matrix]

Ok. Inside this nms class you need to step the finder algorithm until it found a block or is done and didnt find a block.
If it found a block you need to let the horse have a different AIGoal -> Pathfinding to the found loction.

[lost matrix]

Sure

[lost matrix]

By name? By UUID? By object inside the world?

[ornate patio]

wait so first of all how do I get the target block that the blockfinder has found

and how would it navigate around obstacles?

[lost matrix]

yes

[ornate patio]

how lmao

[pallid forge]

Not 100% sure, but I think by string, cause I want to set a gamerule for that world and need a reference to it, so I think its name would work

[ornate patio]

would I use getNavigation().moveTo() for a bunch of different block positions?

[lost matrix]

Do you want to set the gamerule of the world a player is currently located in?

[pallid forge]

Yes

[lost matrix]

the just call player.getWorld()

[pallid forge]

oh lol thats really easy

thanks

[ornate patio]

@lost matrix So what I'm getting so far is this:
Override the tick method of the NMS horse, make it step the algorithm 10 times. (with a super call first of course)

Create a pathfinder goal that will start if a target block is found by the block finder, and finish when the horse can no longer reach that block or its hunger/thirst requirement is done.

but how do I get the target block from the block finder, and how would I make the horse navigate around obstacles?

[lost matrix]

The BlockFinder only finds Blocks the horse can navigate to. So all you need to do is let the Horse navigate to the Block at once.

[ornate patio]

with one getNavigation().moveTo()?

[lost matrix]

Actually the StepAlgorithm needs to be adjusted.
step() should return a StepResult instead of a boolean.
[SUCCESS, PROGRESS, FAILURE]

[ornate patio]

is StepResult a custom enum?

[lost matrix]

Yes it should be a custom enum

[ornate patio]

ok done that

[tender shard]

does someone know how I can set the log level per thread in logback?

I managed to make a plugin that hangs the server without any loogs

[iron glade]

Any idea why this always says the slot's size is 0?

    public void addItemToRandomSlot(Player p, ItemStack item) {

        List<Integer> slots = new ArrayList<>();

        for(int i = 0; i<35; i++) {

            if(!(p.getInventory().getItem(i) == null) && p.getInventory().getItem(i).getType() == Material.AIR) {
                slots.add(i);
            }

        }

        Bukkit.broadcast(Component.text("" + slots.size()));
        Random r = new Random();
        int slot = slots.get(r.nextInt(0, slots.size()));

        p.getInventory().setItem(slot, item);

    }```
```java.lang.IllegalArgumentException: bound must be greater than origin```

[valid sorrel]

is there any way to debug it

[eternal night]

I mean

generally indentify what might hang the server

[valid sorrel]

my plugin has a part about reading the log

maybe it reads the log and every time it logs

[eternal night]

your edge case is an empty slots list. in which case r.nextInt(0, 0) errors

how do you read the logs

[valid sorrel]

getting root logger then adding appender

[iron glade]

Yeah but why isn't anything added to the list even though the test inventory has empty slots

[eternal night]

because iirc getItem(int) on an inventory would return null for an empty slot

[eternal night]

can you share some code ?

[iron glade]

Oh so I have to use ```if(p.getInventory().getItem(i) == null || p.getInventory().getItem(i).getType() == Material.AIR) {

[eternal night]

Yea

[iron glade]

Makes sense

ty

[eternal night]

should also obviously check if slots is empty

else your code errors when someone has a full inventory

[valid sorrel]

hmm

so until reading the console it works

but then I send it to websocket

using this library
https://github.com/TooTallNate/Java-WebSocket

maybe it logs stuff when I send?

but the thing is I don't have any sockets open so it shouldn't send in the first place

[outer wadi]

Is there any library in Java for some "time parser" with a String? Like 3h would give me whatever it could be whatever ms there is in 3h or just a new Date + the 3h

Preferably that doesn't require me to pass in a full date string like 0d 3h 0m 0s

[iron glade]

Is there a way to launch a player more than ~60 blocks?

Which one for example? Should look smooth

[sharp flare]

In the y axis or x/z?

[iron glade]

y axis

[sharp flare]

#setVelocity

[iron glade]

Already doing that, but no matter how high I set the y the player is still not launched more than 60 blocks up

[valid sorrel]

yeah 4 blocks/tick is the maximum veloocity

you have to repeatedly launch the player every tick until the player is at the point in which they will be able to reach 60 blocks

[iron glade]

hm okay

[quaint mantle]

anyone can help me please?

just read the exception

Somehow cant find the wiki article on it, but understanding basic Java exceptions is a must

[obsidian roost]

hey I'm new to config stuff, how would I access the encircled objects in an arraylist?

U can get it as a set

Not arraylist

Config#getConfigurationSection("Parkour.1").getKeys(false)

[obsidian roost]

ah ok thanks a ton then

[humble tulip]

That just gets the naems

[dusk flicker]

There is probably a library those already Pvbble, wouldent be surprised lol

Check out https://github.com/topics/tournament-bracket?l=java

Check that out on how they did it

and then you can make it from that

[ivory sleet]

well if said tournament alr played out

why not a binary tree structure

[dusk flicker]

Personally id overcomplicate it

Make a good few objects, few enums etc

whole constructor to create a tree in real time

[mortal hare]

i finally made it. After SO MANY ATTEMPTS ITS FULLY SYNCED

fully hidden player's inventory contents, you cant interact with player inventory at all

and it restores to the previous state after inventory has been closed

[ornate patio]

A library could’ve done for you lmao

[quaint mantle]

hopper gui?

[ornate patio]

inventoryframework

[quaint mantle]

thats simple

[mortal hare]

this is packet based, so no storing of items is done

[quaint mantle]

whats the point of that

[mortal hare]

lemme show you

resource pack uis can now overlay the player's inventory

by using technique with font bitmaps

you can make interactable menus without having items inside the GUI, which can be accidentally moved and due to ping the overlay would wobble in that case

with trading gui

[quaint mantle]

😮

isnt that already doable tho

[mortal hare]

you can do that but in that case any player's contents will be visible through the overlay

but this is mostly for uis that are big

for example you cant create item model that can overlay contents

bigger than a scale of 4

for trading gui scale of 4 isnt enough to properly overlay

[river oracle]

you know thats a smart approach now that I think about it

just making it look like the item was never put in the inventory

by manipulating packets

I've been dwelling on how to do something similar.

[mortal hare]

im not sure if IF would hide player's inventory contents, since it requires either storing the player's items or manipulating container synchronization

here's the packet handling in action

armor slots are not being removed while ui is open

[river oracle]

this is actually a neat concept dude are you going to open source your code?

[mortal hare]

i think so, im working on UI lib rn so

[river oracle]

I'm working on one as well ironically

though who isn't working on a UI lib

[mortal hare]

it was a pain in the to make it

[river oracle]

I haven't even gotten to custom textures yet I'm still working on base stuff

[mortal hare]

its very hard since player's inventory is really hardcoded so i needed to inject packet handling and send packets manually to the player to sync it also, i needed to prevent PICKUP_ALL action from collecting items of the invisible player's inventory contents, so i needed to remove literally Slot objects from NMS container menu in order to achieve full sync

[river oracle]

https://github.com/Y2Kwastaken/ArcticInventories/tree/revised this is what I got for my lib so far. I haven't even touched custom textures yet though

[mortal hare]

cool

[daring egret]

    public void onMenuClick(InventoryClickEvent e) {

        if (e.getCurrentItem() == null) return;

        if (e.getView().getTitle().equalsIgnoreCase(ChatColor.YELLOW + "Punishment Menu")) {
            if(e.getSlot() == 13) {
                e.setCancelled(true);
                e.getWhoClicked().sendMessage("Stop That");
            }
        }
    }

}```

can someone tell me why this is just not registering the click

i've tried checking the material, the display name and the lore

[river oracle]

did you register the event

[daring egret]

        //GUI COMMANDS & GUI EVENTS
        getCommand("punish").setExecutor(new PunishCommand());
        getServer().getPluginManager().registerEvents(new PunishGuiListener(), this);

yeah

[river oracle]

did you add debugs to see where it cuts off at

oh shit

lmfao

I'm so stupid

[daring egret]

lol?

[river oracle]

you need the @EventHandler annotation

you don't have one

[daring egret]

oops

i'm such an idiot lmao

thanks man

It works now xD

[river oracle]

happens toe veryone

[daring egret]

yo

another question'

i'm struggling really bad with giving a variable to another class

it's breaking a lot

[river oracle]

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[daring egret]

ooh

wat

i don't really get it

[river oracle]

Learn more Java before coding a plugin then

[daring egret]

lmao

ok

[river oracle]

Di is an industry standard

[stone heath]

How can I implement dialogue as a part of my plugin? As in ask a question, get a response back and then ask another question based on the response(already set responses ofc), etc.?

[sweet pike]

How can I achieve a chat colour gradient like the one below?

[short raptor]

Is there a way to change the max amount of hunger meatsticks similar to how you can change the max amount of hearts?

[short raptor]

And also bump this guys question cause this is a really cool effect and I wanna do it too

[stone heath]

I believe if you search up hex gradient generator, you can make a gradient and it'll give you the hex code, which you can apply to the message

[sweet pike]

gotchu, thanks

[sweet pike]

so essentially all of this is shoved into one ChatColor.of?

[stone heath]

This is a good website for the generator: rgb.birdflop.com

[stone heath]

Yea I think so

[sweet pike]

okay! thanks

[dry marsh]

hi everyone

can i get some help?

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[dry marsh]

ok

so im trying to make a loot crate

where the player right clicks the item

and then it subtracts one and then gives them loot

i figured out the right click and the subtract but not the loot

i have certain items i want to give them but i dont know how you would pick some from those

[vocal cloud]

Store the items in a database and then query them based on chest opened? Use a yml config? I don't understand your exact dilemma.

[dry marsh]

no but i dont want to give them all

how do you pick like certain ones

[earnest forum]

basically trying to figure out a random loot system

like a loot table

[dry marsh]

here is my current code

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

[earnest forum]

what is that language

asm?

[vocal cloud]

You sent it in java bytecode looking stuff lol

[dry marsh]

so do i need to code a random function?

[vocal cloud]

What did you send us lol

[dry marsh]

LootCrate.asm

[vocal cloud]

Lmfao

Yeah if you're doing asm then you'd definitely need to write one yourself there

[dry marsh]

ok, will look into it. so then i just call the random function to give the list of items?

[vocal cloud]

Not an asm expert. This is after all a java focused server

[dry marsh]

ah okay ill try to ask on minecraft forum, thanks!

[quaint mantle]

this brotha sent in assembly

wtf

pretty impressive

[humble tulip]

Wat

He's making a plugin in assembly?

[quaint mantle]

that would be something

its like the shit that i sent in this server sometimes

fn main() {
    println!("Hello, world!");
    let binding = core::iter::Iterator::collect::<Vec<u8>>(core::iter::IntoIterator::into_iter(0u8..=8u8));
    let bytes = Vec::<u8>::as_slice(binding.as_ref());
    println!("{}", usize::from_be_bytes(core::result::Result::<[u8; std::mem::size_of::<usize>()], std::array::TryFromSliceError>::unwrap_or_else(core::convert::TryInto::<[u8; std::mem::size_of::<usize>()]>::try_into(&bytes[1..][..std::mem::size_of::<usize>()]), |err| { std::process::exit(core::iter::Iterator::map(core::iter::IntoIterator::into_iter(String::as_bytes(&ToString::to_string(&err))), |b| *b as i16).sum::<i16>() as i32) })));
}

[iron glade]

Does anyone have an idea how I would check if a player is falling?

[earnest forum]

velocity?

[iron glade]

yeah

What I'm currently using is checking #getVelocity().getY() < 0

but this is kinda buggy since I found out the main y velocity when standing around is -0.0078

[earnest forum]

maybe make like a threshold

some small decimal like -0.05

[humble tulip]

Also check if they're on the ground ig

[iron glade]

Is there a way to calculate like the gravity or smth?

currently on my server the main y velocity seems to be -0.0784000015258789 and idk if this can be changed or smth

[humble tulip]

What're you tryina do?

[iron glade]

Checking if a player is falling and as soon as he hits the ground do stuff

currently having a runnable firing in the move event

[humble tulip]

That's tough

What abt if they fall in water?

[iron glade]

already taken care of that

[humble tulip]

Can't a runnable that checks if the player is on the ground each tick sort that for u?

If not on ground and velocity negative falling

If on ground, falling stopped

^^ if they were previosly falling

[iron glade]

yeah thats all working out the only problem is the event keeps firing like 20 times after im cancelling the task

[humble tulip]

What event?

[iron glade]

MoveEvent

seems to be really triggerhappy

[humble tulip]

Well yeah

Looking around with ur mouse trigfers moveevent

[iron glade]

I'm spawning a firework as soon as the player lands on the ground and it keeps firing like 20 times

can't get it to fire only once

[humble tulip]

Can u send code?

When they're falling, put them in a set called falling

When they're onnthe ground, if they're in the set, that means that the player fell

So you can do whatever and then remove them from the set

[iron glade]

I'll try that give me a sec

[humble tulip]

That way when the runnable checks on tje next tick and sees the player on tje ground, it does nothing since they're not in the set

[restive mantle]

is there a way to get all the structures that exist as a list. Structure manager shows it have none in it

[restive mantle]

Random can return the same value multiple times

[smoky oak]

set the seed to system time in nanoseconds

[quaint mantle]

you're lucky

show your code

[smoky oak]

isnt it just that he initialilzes it too fast?

[quaint mantle]

idk]

[smoky oak]

probably is:

Additionally, default-constructed instances do not use a cryptographically random seed unless the system property java.util.secureRandomSeed is set to true.
I think its just using the system time in millis as seed, but i could be wrong

[iron glade]

Not a dev related question but maybe someone can help me out, are there any other MLG types in MC besides water bucket, cobweb and haybale? (ignoring slime blocks)

[earnest forum]

ladder

[quaint mantle]

latter

[quaint mantle]

honey blocks

[smoky oak]

random should have a setseed method. I'm unsure if it works in this instance, but you could check if ThreadLocalRandom#current#setseed#nextInt works

[quaint mantle]

end portal

[smoky oak]

um

isnt that the seed

ah no its not

[quaint mantle]

you're actually getting the same number every time?

[smoky oak]

its possible that your jvm initializes the same way every time

[native nexus]

What about using SecureRandom ?

[iron glade]

oh yes of course, ty!

[quaint mantle]

lava bucket

[native nexus]

https://docs.oracle.com/javase/8/docs/api/java/security/SecureRandom.html It's pretty much the same but safer

[crisp steeple]

anyone know how to get the windowid of the inventory a player is in? ive tried doing this but it just opens a wrong inventory, and doing some debug on client and server shows the id this returns isnt the same one the client opens

[humble tulip]

use a for loop

[smoky oak]

doesnt work

one layer deep lava doesnt absorb fall damage

[humble tulip]

no like

for (int i = 0; i< 1000; i++) {

like that

and print 1000 random numbers

[quaint mantle]

Ok 2 layer

[humble tulip]

then something si wrong with your computer

[smoky oak]

why dont you just use math random

[native nexus]

SecureRandom is thread safe

It extends random

[smoky oak]

multiply it by your maximum value + one, then cast it tointeger

[humble tulip]

Random random = new SecureRandom();

random.nextInt();

[native nexus]

No worries, why do you need to multithread it btw? 😮

[shy shadow]

Hey guys !
Quick question about the docs !

I'm reading this right now : https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerAdvancementDoneEvent.html

And was wondering, looking at the getAdvancement() method, I see that it returns the completed advancement.
How can I know on which form it returns it ? Like how do I know how to compare it with an existing advancement please ? 😄

[humble tulip]

It returns an advancement object

To compare it you can compare the keys

Of the advancement

Not sure if there's a better way

Advancement#getKey

[sweet pike]

could you help me with the formatting? i'm not quite sure how i am supposed to do this

[shy shadow]

Okay thanks a lot, and how do I know what a key look like and matches which advancement ? In the docs ? 🤔

[humble tulip]

a key is a namespacedkey

it's made of 2 parts, the namespace and the key

hence the name

the namespace can be for eg. bukkit or minecraft or your plugin name

the key is like the advancement name or whatever

just do key.eqauls(otherKey) to compare em

[shy shadow]

Ok I see ! Thanks a lot for the quick course, really helpful ! ❤️

[grand hull]

How to make an array of all players names?

thank you

[humble tulip]

Bukkit.getOnlinePlayers().stream().map(HumanEntity::getName).toList().toArray(new String[0]);

shorter^^

[chrome beacon]

String[]::new 🙂

[humble tulip]

:o

Why does List#toArray require an array

And the method that doesn't requires casting

[hollow belfry]

when i try to register login authme with bedrock account in java server there come cheats are not allowed

how can i fix it

[grand hull]

It says "Can't resolve method toList in Stream" How do I fix it?

[ivory sleet]

just use toArray directly

[humble tulip]

But then u have to cast :(

[ivory sleet]

nope

[humble tulip]

Really?

[hybrid spoke]

why would you if you already pass in the type

[ivory sleet]

toArray(IntFunction<A[]> generator)

[humble tulip]

why does it need an IntFunction?

[ivory sleet]

the length

[chrome beacon]

toArray(String[]::new)

[quiet ice]

Or Just use an Array of length 0

So .toArray(new String[0])

Oh actually that is stream

[humble tulip]

ye

[quiet ice]

Probably works either way heh

[humble tulip]

this works

but not new String[0]

that's really dumb

[shy shadow]

@EventHandler
    public void onAdvancement(PlayerAdvancementDoneEvent e){
        Advancement advancement = e.getAdvancement();
        Player p = e.getPlayer();

        if (advancement.getKey().equals(NamespacedKey.minecraft("story/upgrade_tools"))){
            p.sendMessage("action to do here");
        }
    }```

I'm doing something wrong I think, but can't really figure out what 🤔

[humble tulip]

uhh

[quiet ice]

Gotta Love consistency

[humble tulip]

are u sure the upgrade tools namespacedkey is story/upgrade_tools?

[hybrid spoke]

because its a function to explicit call ::new

[shy shadow]

I'm not 100% sure, I didn't really know where to find the info, found on the fr-minecraft.net website that they display the ID of advancements

So I assumed it was it xD

[humble tulip]

        String[] names = Bukkit.getOnlinePlayers().stream().map(HumanEntity::getName).toArray(new IntFunction<String[]>() {
            @Override
            public String[] apply(int i) {
                return new String[0];
            }
        });

it requires an intfunction just to create an array the size of the stream???

[static ingot]

Just use String[]::new

instead of that ugly mess, kek

[humble tulip]

ye ik but like why does it need it in the first place?

[static ingot]

the int is the array size

it just initializes an array with the specific size necessary

[humble tulip]

yes but why cant it just do that internally

or why does toArray() return an Object[] and not T[]

it's just stupid

Bukkit.advancementIterator().forEachRemaining(advancement -> System.out.println(advancement.getKey()));
@shy shadow

[static ingot]

the IntFunction also gives it the type so that it can return it as T

[humble tulip]

put that to see all the advancements

[static ingot]

lol

[shy shadow]

Ooh thanks, I was doing something similar to reach that too haha

p.sendMessage(String.valueOf(advancement.getKey()));

Tried to do that on the event xD

[humble tulip]

that's also possible ye

[shy shadow]

It didn't work sadly

Will try your 😄

[humble tulip]

also this

why cant it just be a List<Player>

if i want it to be a list<Player> i need to cast it

[alpine urchin]

i think its a set and even an array on some older versions

[shy shadow]

omg minion I'm so sorry

I've been trying this for 2 hours and just realised I didn't registered the event LOL

[humble tulip]

:/

LOL

It's alright

Happens

[quiet ice]

Because of generics erasure - it must somehow get an instance of Class<T> in Order to create T, which in your Case is Not applicable

[shy shadow]

Hahahaha minion imma go back to sleep

I was also connected on the wrong server

XD

Btw it works perfectly now, thank you very much for your help !

[humble tulip]

Ohh cuz they used ?

[vital ridge]

Iam creating a random teleport plugin. My goal is to load the chunk before teleporting there so the player won't hover in void. I'm on version 1.8.8. How could I achieve that? I can do chunk#load() but I can't set it to be force loaded so it unloads before I get there.

[opal juniper]

if you load the chunk without any reason to keep it loaded it will just be unloaded - you need to update to modern to use plugin tickets

[vital ridge]

So you cannot really achieve that in 1.8.8?

What about ChunkUnloadEvent?

I could cancel that.

[opal juniper]

no you cant

it doesnt implement Cancellable

[tender shard]

Just use World#setChunkForceLoaded https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#setChunkForceLoaded(int,int,boolean)

oh that's also not available in 1.8 lol

I wonder if the 1.8 api has any features at all

[hybrid spoke]

just load it again on unload

[vital ridge]

Yeah but chunk takes time to load doesnt it? If I constantly do load() on unloadEvent it would be pointless.

[tender shard]

that's how other chunk loaders do it in 1.8

[dawn hazel]

    @EventHandler
    public void onInteractEvent(PlayerInteractEvent e) {
        //Check if action was right click

        if (e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) {
            e.getPlayer().sendMessage("test");
        }
    }```
for whatever reason its sending doubles of the same message and i dont know why

[vital ridge]

I'll give it a try.

[tender shard]

the event gets called once for each hand

[hybrid spoke]

for the first time maybe, but after that it should be cached somewhere iirc

[dawn hazel]

i see

[hybrid spoke]

and even that "takes time" isn't much
