[fathom nova]

you have >=

[paper geyser]

yup

just realized

[chrome beacon]

Well you're not calling it

[fathom nova]

it should be <

[kind coral]

anyone?

[paper geyser]

yup

[heavy void]

org.bukkit.craftbukkit.v1_8_R3.block.CraftBlockState cannot be cast to org.bukkit.material.Directional
``` whyyyy

[fathom nova]

you cant cast material to block state

[heavy void]

Im using the wrong directional? ' -'

[fathom nova]

Think so

[chrome beacon]

It tells you to upgrade client or change auth type

[heavy void]

What is the correct directional

[fathom nova]

I'm not sure

but it's something like org.bukkit.block.Directional

if that exists

why do you need blockstate

[kind coral]

so how could i do that? i run mysql workbench

[chrome beacon]

You don't cast state. This isn't a modern version

[heavy void]

How i cast the state

[chrome beacon]

You don't

[heavy void]

How i use directional on the block ,_,

[chrome beacon]

You create new MaterialData from the Material then cast that

I think..

[lost matrix]

If you want to use Directional on a block you need to

1. Get the BlockData of a Block
2. Check if its instance of org.bukkit.block.data.Directional
3. Cast it to org.bukkit.block.data.Directional

[chrome beacon]

1.8

[lost matrix]

Ah. Then:

1. Update
2. Do the stuff from above

[heavy void]

1.8 ' -'

It dont has org.bukkit.block.data ' -'

[chrome beacon]

Yeah do what I said

[heavy void]

Ill try put and modify this at my blockutils and try use.

at setFacingDirection

[chrome beacon]

Um that should get taken down lmao

[narrow vessel]

Latest compiled binaries and full source code

uh huh

totally legal

[heavy void]

Idk if this is legal, i only searched Spigot 1.8 setFacingDirection

[narrow vessel]

n

o

[lost matrix]

Its even for 1.8.4
And its def not legal

[heavy void]

uh, so, sorry.

[chrome beacon]

Anyway do what I said then getMaterial and set the new block

[heavy void]

Idk how to do that

[chrome beacon]

What part

[heavy void]

Idk how to create a MaterialData

[chrome beacon]

new MaterialData

[heavy void]

Idk how to interact with MaterialData ' -'

[chrome beacon]

.-.

Just create a new MaterialData

[heavy void]

Im saying about bytes

[chrome beacon]

Yeah blocks have byte values in 1.8

Use getData on the block

Wrong channel

[heavy void]

Im saying, how can i convert blockface to byte

[chrome beacon]

Why are you converting BlockFace

[heavy void]

I want to use BlockFace

or yaw

[chrome beacon]

For what

[gentle meteor]

Even when i cast it for some reason it still is CraftBlock

[heavy void]

Im making a mystery box plugin that has a command to add new mystery box to the map, and i want it to go directly on player direction.

[gentle meteor]

Like the compiler removes the cast for being unnesesary

[chrome beacon]

Yeah so do what I told you

I need you to trust me here...

Just do exactly what I said

[chrome beacon]

Yeah that's because it is

[lost matrix]

Casting doesnt change the actual type of an Object

[torn shuttle]

oh wow I managed to permanently brick my intellij install

[chrome beacon]

How lmao

[torn shuttle]

no clue

it updated some plugins and seemingly bricked itself in the process

[gentle meteor]

Congrats on begoming a java ™️ teveloper

[torn shuttle]

you mean Oracle ™️ Java ™️ developer?

[gentle meteor]

Still less paim than c

[torn shuttle]

c# is lit tho

[gentle meteor]

Thats literaly like comparing javascript and java

[lost matrix]

Huh?

Are you speaking of C# ?

[gentle meteor]

Yep comparing c# and c

[torn shuttle]

lol which one is js in this metaphor

[lost matrix]

Ah. I thought comparing C# and Java

Because those are basically the same language

[torn shuttle]

that's why I like it

easy to learn lol

if you know java and js it's fat stacks easy street

[lost matrix]

I really like delegates

And the fact that types dont erase at runtime

[torn shuttle]

I've not done enough c# yet to see downsides but so far it feels a lot like java but slightly better

[lost matrix]

But if Java had those two features i wouldnt give C# a second thought

[lost matrix]

I dont like the way access modification is done

[heavy void]

But how this will work with what i want?

[chrome beacon]

Because I'm helping you get the Directional interface .-.

[queen niche]

if(sender instanceof Player) { Player player = (Player) sender;

How do I change this in so it also lets command blocks use this command?

[torn shuttle]

oh boy

commandsender

or bust

[heavy void]

But idk how to use bytes

[lost matrix]

if sender instanceof BlockCommandSender

[queen niche]

does this also let players use it?

[chrome beacon]

Just use getData on your block to get the byte. Or just skip it, byte isn't important here and will be overriden

[queen niche]

or only command?

[torn shuttle]

did nnya show up and get banned again since the last time I saw him?

[chrome beacon]

I think so

[lost matrix]

No idea but probably. Guy comes on every few hours

[lost matrix]

If you let them. Sure.

[torn shuttle]

what a bizarre behavioral pattern he has

[lost matrix]

Every CommandSender can execute every command. How you handle the different types of CommandSender inside your method is completely up to you.

[queen niche]

Ah okay! thanks for explaining!

[quaint mantle]

https://paste.md-5.net/fuveqofope.cs
i can open an inventory from "shop" but not anywhere else

[heavy void]

    MaterialData mdata = new MaterialData(Material.ENDER_CHEST);

```what i do now?

[torn shuttle]

draw the rest of the owl

[chrome beacon]

Now cast mdata to Directional

[heavy void]

Idk how to cast something ;;-;

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

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

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

[torn shuttle]

(cast)something

[heavy void]

Uh

[lost matrix]

Example:

  @Override
  public boolean onCommand(@NotNull CommandSender commandSender, @NotNull Command command, @NotNull String string, String[] strings) {
    if (commandSender instanceof Player) {
      commandSender.sendMessage("You are a player.");
    } else if (commandSender instanceof BlockCommandSender) {
      commandSender.sendMessage("You are a command block.");
    } else {
      commandSender.sendMessage("Only a player or command block can execute this command.");
    }
    return true;
  }

[heavy void]

uh

lol

[torn shuttle]

did you just assume my command sender type?

[lost matrix]

triggered

[queen niche]

Thanks! Gonna save this

[heavy void]

It is what i made with egtState()?

[torn shuttle]

(((triggered)triggered)triggered)

[heavy void]

Directional mdir = ((Directional) mdata); ?

[chrome beacon]

Yes

[heavy void]

I dont know the name lol

[chrome beacon]

Now use mdir to set facing

[heavy void]

But now i know lol

[tame coral]

Directional mdir = (Directional) mdata; is fine

no need for those parenthesis

[torn shuttle]

brackets and parenthesis are different things

[tame coral]

yeah mb

[quaint mantle]

Is there any way to pass in the getCommand method as an parameter to another method?

[tame coral]

i'm not fluent in english lol

[torn shuttle]

[] brackets () parenthesis {} curly braces/brackets

[tame coral]

corrected me

[lost matrix]

You should def use googles BiMap for stuff like this

    private String getKey(Inventory inventory) {
        Map<String, Inventory> map = manager.getInventoryMap();
        if (!map.containsValue(inventory)) return null;

        for (String key : map.keySet()) {
            if (map.get(key).equals(inventory)) return key;
        }
        return null;
    }

[quaint mantle]

?

[lost matrix]

Assuming that values are unique

[heavy void]

Directional mdir = ((Directional) mdata);
```and now?

wait

my control + v isnt working

lol

[torn shuttle]

can't you use if key contains inventory directly there

[lost matrix]

You cant pass methods to other methods. The question doesnt really make sense.

[chrome beacon]

Wait I just realized you can do new EnderChest(BlockFacing)

[heavy void]

mdir.setFacingDirection(BlockUtils.yawToFace(this.location.getYaw(), false));

What i do with this now

[quaint mantle]

I'm trying to make a command handler but i'm struggling on registering the command

[heavy void]

Im using .setType to set the block.

[lost matrix]

Its also really bad practice to pass data structures like maps between classes. That should be avoided at all costs.

[quaint mantle]

what do i do

[quaint mantle]

wait i think i found a solution

[chrome beacon]

Yeah so use new EnderChest(BlockData) instead of casting directional or new Material. When you've done that call getData on the EnderChest and use that byte in the setType method

[lost matrix]

You should have methods inside the class that contains the data structure to modify it.
Like
giveInventoryOfKey(String)
or
clearKeys(), sortValues() etc.
Just never pass the data structure to other classes

[quaint mantle]

ok

[cold tartan]

is there a way to make momentum last for longer? like less drag?

[torn shuttle]

vector math

[lost matrix]

The physics are hard coded. So you would have to do some hacky stuff to keep an entity moving.

[heavy void]

And how can i get a blockdata from a materialdata ' -'

[cold tartan]

ok, ty

[chrome beacon]

Use EnderChest not MaterialData

[heavy void]

Then...
Why i made a materialdata...

[chrome beacon]

Because I found the EnderChest interface

You know I haven't done this before either

I'm literraly just looking around in Javadocs

[carmine urchin]

What would be the best way to store wins and losses and points (such as coins and gems and such). Would it be better to use static or use a class with constructor to make a manager? {

[lost matrix]

2 or 3 more years and 1.8 is a decade old. Nobody wants to use ancient software. Thats why getting help for it will get harder and harder as time passes.

[lost matrix]

Generally:
Singleton Manager > static data

[carmine urchin]

thank you

[shadow gazelle]

I give up at this point lol

My plugin keeps saying item is null in this

size: 54
itemshop:
    categories:
        blocks:
            slot: 10
            item: "WHITE_WOOL"
            name: "&7&lBlocks"
            lore: "Blocks for building"

String mat = file.getString("itemshop." + category + ".item");
ItemStack item = new ItemStack(Material.getMaterial(mat));

That's in a for loop going through the categories

[paper viper]

Uhhh you are doing .item

Not like .blocks?

Unless I’m seeing something wrong

[heavy void]

lol

[shadow gazelle]

blocks is the category

[paper viper]

What

[heavy void]

uh

[paper viper]

That doesn’t make sense

[shadow gazelle]

How

The loop loops through all of the keys under categories

[heavy void]

If blocks is the category, you dont need to put "itemshop.categories." + category?

[shadow gazelle]

blocks is a category

[heavy void]

Its like you doing itemshop.blocks.item

Dont itemshop.categories.blocks.item

[shadow gazelle]

What

[heavy void]

.

[heavy void]

Your code is doing itemshop.blocks.item

[shadow gazelle]

How the fuck did I forget that

big brain time

Thanks

[heavy void]

lol

np

[shadow gazelle]

Excuse me while I die

[heavy void]

It keeps returning null? XD

[shadow gazelle]

No

Just that I did dum

Ah yes

You close Minecraft and it keeps starting anyway

very nice, Forge

[heavy void]

Minecraf is a game made in a 4x4 house ' -'

[shadow gazelle]

Watch it crash when I try to open the GUI

[heavy void]

Maybe you need to use a material formatter, not?

[shadow gazelle]

Aaand I forgot to cancel the click event

n o i c e

Wait

[heavy void]

Lol, my server is returning Timed Out ,_<

[shadow gazelle]

No, I wasn't doing click events yet

[heavy void]

LOL, my Yaw to BlockFace converter is getting the opossite face

Why i need +1 restart, god? ,_<

EnderChest ec = new EnderChest(BlockUtils.yawToFace(this.location.getYaw(), false).getOppositeFace());
    this.block.setType(Material.ENDER_CHEST);
    this.block.setData(ec.getData());
```Its finally workinggggg.

[hybrid spoke]

heard my name?

[shadow gazelle]

How would I have to translate color codes in a string list?

[hybrid spoke]

loop over

[lost matrix]

Iterate over the list and translate each String

[manic bison]

hey, anyone knows how to disable spectator menu when someone is on spectator mode ?

don't seem to find it on google

[lost matrix]

I think thats just client side

But never investigated it

[manic bison]

but on server siude, is there a way to cancel teleport

[ivory sleet]

probably

[lost matrix]

That for sure

[ivory sleet]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerTeleportEvent.html maybe

[manic bison]

so it'd be
on player teleport
if player is on spectator
event.cancel ?

[lost matrix]

pretty much

try it out ^^

[manic bison]

alrighty i'll try it, thanks

[heavy void]

Theres a way with Teams.

[manic bison]

umm the problem is thaat while on spectator, i teleport the player, so it's gonna cancel the teleport event, anyway for my teleport event to bypass the restriction on PlayerTPEvent ?

[lost matrix]

Sure. Use a Set<UUID>

[manic bison]

player's UUID? or what do you mean

[lost matrix]

Example:

  private final Set<UUID> bypassedPlayers = new HashSet<>();

  @EventHandler
  public void onTeleport(final PlayerTeleportEvent event) {
    final Player player = event.getPlayer();
    if (player.getGameMode() == GameMode.SPECTATOR && !this.bypassedPlayers.remove(player.getUniqueId())) {
      event.setCancelled(true);
    }
  }

  public void tpWithBypass(final Player player, final Location tpLocation) {
    this.bypassedPlayers.add(player.getUniqueId());
    player.teleport(tpLocation);
  }

To make it more clear:

  @EventHandler
  public void onTeleport(final PlayerTeleportEvent event) {
    final Player player = event.getPlayer();
    
    final boolean isSpectator = player.getGameMode() == GameMode.SPECTATOR;
    final boolean isBypassed = this.bypassedPlayers.remove(player.getUniqueId());
    
    if (isSpectator && !isBypassed) {
      event.setCancelled(true);
    }
  }

[manic bison]

alrighty, so the second code works ?

[lost matrix]

Everything there should work

The second code is the same as the first. Just written more verbose.

[hasty prawn]

Is there a benefit to writing final before everything

[tame coral]

A entity's unique id (or UUID) is an id they're attributed

Every entity has a UUID

And, as its name states, it's unique

[manic bison]

yep

[lost matrix]

Yes. It makes it clear that the variable should not be redeclared. Also every variable is automatically qualified for usage in anonymous classes and lambdas.

[hasty prawn]

Hm, I guess. Aren't they still qualified if they're effectively final anyways?

[lost matrix]

So it makes the intent of the code much more clear. Depending on your code, it serves as a hint for the compiler to potenitally enable optimizations.
It also makes them thread safe by default.

[hasty prawn]

Hm interesting, thanks

[lost matrix]

I just configured my IDE to fill those things in for me and it helped me write cleaner code for a while.

[hasty prawn]

I usually know when my variables shouldn't be redefined, but I do understand the use if you're working in a team environment

[dense goblet]

How can I check if an item can be damaged

[lost matrix]

Check if the ItemMeta is instanceof Damageable

[dense goblet]

ah ty

[lost matrix]

You can also see if Material#getMaxDurability() yields the results you want.

[grim ice]

im rly bored anyone has an idea of a plugin

[torn shuttle]

asking again, does anyone know if loading worlds is possible on load instead of on enable?

[lost matrix]

A plugin to import simulations and animations from blender so you can have giant moving creatures that are made out of blocks

[chrome beacon]

Um why

[lost matrix]

I would suspect that its not. onLoad happens really early in the application.

But then i also dont see a reason to do that.

[torn shuttle]

I want to guarantee that world loading happens before I try to load things in them and in general world loading comes with a shitload of logging data which is largely irrelevant for 99.99% of people but makes it hard to see anything else, especially if you're loading a lot of them

I can just shift stuff around but ideally I'd shuffle it way, way before the core loading part of things

[lost matrix]

Just block console output while your worlds are loading ^^

[torn shuttle]

I might have to, it's getting on my nerves

[dense goblet]

is there an event for an explosion caused by calling world.createExplosion?

[lost matrix]

BlockExplodeEvent

[dense goblet]

really? Thought thats if a block itself explodes

[torn shuttle]

I've never really dealt with console message suppression, what's the starting point for that?

[lost matrix]

Which is what happens if you call World#createExplosion()

[lost matrix]

duckduckgo

[dense goblet]

nah as in, if the block causes an explosion

[torn shuttle]

I need a way to toggle between ddg and google search

easily

[dense goblet]

but I'll give it a go ty

[torn shuttle]

ok so just java then, nothing spigot-side?

[lost matrix]

Just pipe System.out into dev/null or something idk

[chrome beacon]

Do it like me use ddg as default engine but always type google in the searchbar 🧠

[torn shuttle]

iirc firefox had a system to quickly search in a specific location but I had to stop using it because the websites I have to use for work don't support it

[lost matrix]

Probably something in this direction:
System.setOut(new PrintStream(...));

Let me try just setting it to null XD

[torn shuttle]

I'm sort of surprised there's no event for this

sounds like a good event candidate

[dense goblet]

btw why is the yield inverted in the explosion events

[lost matrix]

What do you mean by that?

[lost matrix]

Im this far:

  @Override
  public void onEnable() {
    System.out.println("Test");
    this.getLogger().info("LoggerTest");

    this.disableSTDOut();

    System.out.println("Post_Test");
    this.getLogger().info("Post_LoggerTest");
  }

  public void disableSTDOut() {
    System.setOut(new PrintStream(new ByteArrayOutputStream()));
    this.getLogger().setLevel(Level.OFF);
  }

Console:

[23:34:07 INFO]: Time elapsed: 1177 ms
[23:34:07 INFO]: [SpigotSandbox] Enabling SpigotSandbox v${project.version}
[23:34:07 INFO]: Test
[23:34:07 INFO]: [SpigotSandbox] LoggerTest
[23:34:08 INFO]: Running delayed init tasks
[23:34:08 INFO]: Done (4.158s)! For help, type "help"
[23:34:08 INFO]: Timings Reset

So it suppresses some stuff but not the server logging.

[torn shuttle]

world loading is logged by servers right?

[dense goblet]

yield is inversely proportional to explosion power. i.e. TNT has a yield of 0.25, and a creeper has a yield of 0.33

or whatever (1/creeper power) is

[torn shuttle]

yield isn't inversely proportional, the bigger the yield the bigger the explosion

[dense goblet]

nope, I logged it

in 1.16.5 at least

[torn shuttle]

I've actively used setting yields and I can guarantee that bigger numbers go bigger boom

you can create an explosion yourself

[dense goblet]

I'll test it again ig

what yield are you talking about though

[torn shuttle]

explosion yield

[dense goblet]

when creating an explosion or when receiving the event

[torn shuttle]

I've mostly messed with creating them

[dense goblet]

then that's different

that's power

but yield = 1/power for whatever reason

they use yield in the events

[torn shuttle]

no it's not

or at least the field is called yield

[dense goblet]

that's even worse then

they call it the same but the event has it inverted

[torn shuttle]

why do you think it's inverted

[dense goblet]

since logging it shows that it is inverted

[torn shuttle]

if you didn't know how to set the yield in the first place how do you know the one you're getting isn't accurate?

[dense goblet]

I use tnt which has a known yield of 4

[faint vector]

can someone explain to me as to why when I start a plugin java.lang.ClassNotFoundException: org.apache.commons.io.FileUtils appears even though I included it as a dependency when I compiled the plugin???

[dense goblet]

I'll test again comparing tnt's reported yield (0.25) vs a custom explosion with power 2.5

[torn shuttle]

no, it has a known power of 4

power isn't yield

[dense goblet]

they call it yield as you said

[torn shuttle]

no "they" don't

[dense goblet]

then it has a known power of 4

[torn shuttle]

yes

not a known yield

have you considered that 4 power = .25 yield?

[paper viper]

Did you not shade it in?

And also bukkit I think has that dependency and you need to relocate it

To some different name

[faint vector]

shade it in? I haven't heard of that before

oh

[paper viper]

It’s when you include the classes in the library into your jar file

So your classes can use them directly

[faint vector]

ooooh

[faint vector]

how do you do that?

[paper viper]

Maven or gradle?

[faint vector]

maven

[dense goblet]

checked with a fireball. If you summon one with explosion power 10, reported yield is 0.1

[opal juniper]

U need the compiler plugin

[dense goblet]

if the power is 2, the yield is 0.5

[paper viper]

https://maven.apache.org/plugins/maven-shade-plugin/usage.html

[dense goblet]

for creeper it is 0.333 and for tnt it is 1.0

it seems completely inconsistent

[paper viper]

Then you need to setup as so, and set your dependency to compile

[dense goblet]

also for custom explosion with power 2.5, it says yield is also 1.0

oh wait wow

[torn shuttle]

sounds consistent to me if I assume that you are doing the power wrong and it's just getting default yields

[dense goblet]

yield is the percentage chance to drop blocks

what a terrible naming scheme

[faint vector]

thanks

[dense goblet]

and no javadocs in the jar doesnt help lol

so how do we get the power of an explosion?

[torn shuttle]

no it isn't

[dense goblet]

they must then be doing it differently on different events

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockExplodeEvent.html#getYield()

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityExplodeEvent.html#getYield()

both of these seem to be the same though

you are looking at the creation side

[torn shuttle]

does tnt actually drop 100% of the blocks though

I thought it came with some loss

[dense goblet]

they changed it at some point iirc

recently

[torn shuttle]

well if they changed it after 1.0 it's recent to me

[dense goblet]

so it's impossible to get the power of an explosion from the event...

[faint vector]

alright cool it works now thank you so much!

[paper viper]

How to spawn an Item with ProtocolLib-API for one player ?

I know I need these two:

1. https://wiki.vg/Protocol#Spawn_Entity
2. https://wiki.vg/Protocol#Entity_Metadata

But im not really able to understand and spawn a item!
Im trying to spawn a item with this lines of code:

                        EntityItem entity = new EntityItem(((CraftWorld) loc.getWorld()).getHandle(), loc.getX(), loc.getY()+2, loc.getZ(), CraftItemStack.asNMSCopy(i));

                        PacketContainer item = protocolManager.createPacket(PacketType.Play.Server.SPAWN_ENTITY);
//                        PacketContainer itemData = protocolManager.createPacket(PacketType.Play.Server.ENTITY_METADATA);

                        item.getIntegers().write(0, entity.getId())
                                .write(6, 2);
                        item.getUUIDs().write(0, entity.getUniqueID());
                        item.getDoubles()
                                .write(0, loc.getX())
                                .write(1, loc.getY()+2)
                                .write(2, loc.getZ());```

But instead of an default stone item, it just spawn this https://i.imgur.com/vCe6vb7.png

Before I'm trying to use `ENTITY_METADATA`, I want to `SPAWN_ENTITY` get working xd
Im very very very new to protocolLib's API, but I dont have any idea how to work with it o.O

[lost matrix]

            shulker.setFlag(6, true); //Glow
            shulker.setFlag(5, true); //Invisibility

What is the new flag for Glow and Invisibility? I cant find it

Dude I already mentioned it xd But how to use it right with ProtocolLib ?

So I only need Entity ID, Object UUID, Type, X, Y, Z ? How to set them right ? What did I wrong

[rose aspen]

Did you register your Listener ?

[manic bison]

I did

[rose aspen]

I would recommend to just put overall a System.out.println to test your code is even working.
Place one right at the beginning, like over your event.setDeathMessage(null);

And check if the killer is an instance of Player

[next crater]

How do I check if a player stopped moving? (My ideia is: If a player stopped moving, they die :D, so they need to constantly move :)

[manic bison]

i'm adding one to each condition statement

[lost matrix]

How much does this have to scale?

[manic bison]

PlayerMoveEvent ?

[rose aspen]

Async Task / Threads / I would not recommend PlayerMoveEvent

[next crater]

like 1 second

[rose aspen]

Then just a Thread or Task

Check Pos

Check 2x pos and their distance and so on .. xd

[lost matrix]

You need to ask yourself 3 questions.
How much does my code have to scale
Is there a min delta space step that counts as not moving
Is there a min delta time step that counts as stopping

With scale i mean: How many people do you expect to support?

[next crater]

fuck im dumb

im a begginer with spigot xd

[lost matrix]

Then i would actually just go with the PlayerMoveEvent

[next crater]

ok thx :v

cant I just do:

if (plyaer.getWalkSpeed() == 0) {
// do stuffs
}

somehow?

[torn shuttle]

you're looking for velocity

although iirc it's never 0?

since it's acceleration and there's always a negative y vector

something like that

[next crater]

fuck my life...

ok

so I think I would need to learn how to use the "RunTaskLater"

I searched a little bit

[torn shuttle]

probably not a bad idea

[next crater]

the concept is:

• Create a HashMap (with the last player location)
• Every second (with the RunTaskLater, I think) it would update the HashMap
• If it updates with the same location, then it means that he stopped moving, and then he dies :D

again, sorry if my english sucks 😔

[lost matrix]

Just a quick mock up:

  private static final long MIN_DELTA_TIME_MS = 1000;
  private static final double MIN_DELTA_SPACE_SQ = 0.01 * 0.01;

  private final Map<UUID, Long> trackedTimes = new HashMap<>();

  @EventHandler
  public void onMove(final PlayerMoveEvent event) {
    final UUID playerID = event.getPlayer().getUniqueId();
    final Location from = event.getFrom();
    final Location to = event.getTo();
    final double distanceSquared = from.distanceSquared(to);

    if (distanceSquared > MIN_DELTA_SPACE_SQ) {
      this.trackedTimes.put(playerID, System.currentTimeMillis());
    } else {
      final long timeStanding = System.currentTimeMillis() - this.trackedTimes.getOrDefault(playerID, System.currentTimeMillis());
      if (timeStanding > MIN_DELTA_TIME_MS) {
        // Player stopped moving here
      }
    }

  }

[next crater]

did you test it?

[lost matrix]

Nope

[next crater]

np

[lost matrix]

And there is one big flaw i just realised. If they just stand still for a while nothing happens. Just if they move their mouse ever so slightly the time will get detected.

[next crater]

ok, I'll try to do that tomorrow

thx guys ❤️

[manic bison]

okay, i retested this code

       public void onDeath(PlayerDeathEvent event) {
        System.out.println("Begin");
        event.setDeathMessage(null);
        Player player = event.getEntity(); 
        Player killer = player.getKiller();

             //If the killer has and helmet AND the player doesn't have a helmet : say "player has been killed by unknown"
             System.out.println("killer has helmet AND plyer no helmet");
             Bukkit.broadcastMessage(player.getName() + " s'est fait tuer par un inconnu");

             System.out.println("player has helmet AND killer doesnt have helmet");
             Bukkit.broadcastMessage("un inconnu s'est fait tuer par " + killer.getName());
         }

         if(player != null && !player.getInventory().getHelmet().getType().equals(Material.LEATHER_HELMET) && !killer.getInventory().getHelmet().getType().equals(Material.LEATHER_HELMET)) {
             //if the player doesnt have an helmet AND the killer doesnt have a helmet : say "player has been killed by killer"
             System.out.println("both no helmet");
             Bukkit.broadcastMessage(player.getName() + " s'est fait tuer par " + killer.getName());
         }
        }}else{
        }
       }```

and all conditions doesnt work, checked it with sysouts, only the first sysout works which tells "Begin"
any ideas ?

honestly, sorry for bothering much, but i really cant find the answer i tried everything i could

conditions just arent firing

[ivory sleet]

kinda clustered with comments so slightly hard to tell

[manic bison]

i'll delete

[lost matrix]

You should def group the conditions and early escape

[ivory sleet]

write self expressing code btw 😄

[manic bison]

okay, i retested this code

       public void onDeath(PlayerDeathEvent event) {
        System.out.println("Begin");
        event.setDeathMessage(null);
        Player player = event.getEntity();

       }```

here

[lost matrix]

Example:

Player killer = player.getKiller();
if(killer == null) {
  return;
}

[manic bison]

i'll just replace return with a sysout

[next crater]

just a question, when "return;" appears, like you did, it means that it doesn´t return nothing, right?

sorry if it is a dumb question, but whatever

[lost matrix]

You are right. This happens in method which have the return type void

[manic bison]

alright killer isnt null

[lost matrix]

"it doesnt return anything" but im not a native speaker

[manic bison]

because no sysout

but it tells me on console "exception : null on line 49" which is

if(player != null && killer.getInventory().getHelmet().getType().equals(Material.LEATHER_HELMET) && !player.getInventory().getHelmet().getType().equals(Material.LEATHER_HELMET))

my first condition

[next crater]

thx 🙂

my english never was the best

  @EventHandler
  public void onDeath(final PlayerDeathEvent event) {
    final Player player = event.getEntity();
    final Player killer = player.getKiller();

    }

    final ItemStack playerHelmet = player.getEquipment().getHelmet();
    final ItemStack killerHelmet = killer.getEquipment().getHelmet();

    final Material playerHelmetType = playerHelmet == null ? null : playerHelmet.getType();
    final Material killerHelmetType = killerHelmet == null ? null : killerHelmet.getType();

    final boolean playerHasLeatherHelmet = playerHelmetType == Material.LEATHER_HELMET;
    final boolean killerHasLeatherHelmet = killerHelmetType == Material.LEATHER_HELMET;

    if (playerHasLeatherHelmet) {
      if (killerHasLeatherHelmet) {
        System.out.println("Both have a leather helmet.");
      } else {
        System.out.println("Only the player has a leather helmet.");
      }

      } else {
        System.out.println("Nobody has a leather helmet.");

This code doesnt need comments because the variable names are expressive and tell you exactly what you are trying to do.

oh so bsiclly i can just do this

oh

allright thank you so much ❤️

i'm not rlly good at this, prefer doing just code then comment

i hope so, i started learning java 4d go

all day just clicking & clicking my keyboard

[slow oyster]

Anybody use Hibernate in their plugins? I'm getting a problem when closing the SessionFactory in onDisable() Caused by: java.lang.ClassNotFoundException: org.h2.mvstore.MVMap$2 even though I can definitely see the anonymous classes shaded in the jar

[lost matrix]

Thought about it. Really didnt like my first experiences with it. Then scratched it.

You can block the main thread really fast if you are not careful

[slow oyster]

I use it in work with Spring Boot which is really nice, so thought I'd give it a go standalone

[lost matrix]

Do you fully understand how the lifecycles work and when hibernate is actually accessing a database? Because you really dont want that to happen on the main thread.

Also JAP entities are quite primitive. Serializing more complex data with hibernate is a bit of a hustle.

Especially if they are life Objects

[slow oyster]

I hadn't thought about the main thread issue tbf

[lost matrix]

Because even serializing an ItemStack with hibernate could result in half the server being serialized recursively

You can play around and give me an update if you found a nice way of decoupling the JPA Entity from the main thread. Maybe with a proxy class?

[slow oyster]

I'm currently serializing everything into a YAML file so it can't be much worse. And yeah I was planning on storing most of the Bukkit ConfigurationSerializable's as JSON anyway

[lost matrix]

Ah ok

[slow oyster]

Not sure I get what you mean by decoupling the entity from the main thread though? Do you mean the Queries to get/update entities?

[lost matrix]

Oh you probably dont want full autonomous persistence. So you just want to serialize/deserialize the entities in a DB and then schedule the queries yourself?

[slow oyster]

Yep that's what I'm doing, currently I'm storing everything in HashMaps and Lists in memory etc. And then that all gets serialized into a YAML file when the world file is saved. It's grew fairly fast and so it's not practical doing it all in memory anymore.

[lost matrix]

Holy moly. Too big for memory? You need to have a TON of data then. I lately was on a server project that just kept the data of the latest 5000 users in memory. Didnt even occupy 2 gigs of ram.

[slow oyster]

No it's not too big for memory

It's just annoying to maintain

[lost matrix]

I just throw everything into gson and register custom serilizers for the more complex types. 😄

[slow oyster]

Especially when it's all relational data, and doing all that object orientated is getting annoying.

I.e storing a HashMap with player ID's and everything related to them. Then a hashmap of Locations and everything related to players at that location.

I'm planning on utilizing Geospatial queries for the Locations which will help a lot

[lost matrix]

Oh i see. I normally have a more centralised data approach.
Map<UUID, PlayerData>
And PlayerData contains all the data i need.
Then throw everything into Gson -> MongoDB and hide it behind a AsyncLoadingCache for access to offline data.

[slow oyster]

I basically have HashMap<String, HashMap<String, ChestLinkStorage>> which is UUID -> StorageName -> Object

[lost matrix]

Nested HashMaps -> make a new class that contains the nested map
^^

But do you really want Hibernate then?
Because custom serialization with hibernate is a bit tedious.

[slow oyster]

All I need to store is player UUID's, String and ItemStack's tbh

There's just a lot of relationships between them all

Which is why I think a relational model will work much better

I.e get all Storages that Player X is a member of. Or that Player Y is the Owner of. Will be much easier

[lost matrix]

Sure. I was just thinking that you could use something like Querydsl and build the queries yourself instead of using hibernate for that.

But if you are confident with custom mappings then go for hibernate

[slow oyster]

I thought I need to use those on top of Hibernate?

Hibernate will automatically update database schemas for me too on upgrades

[lost matrix]

No. With hibernate you just do something like
hibernate.persist(object) and you are done. You dont see a single query there.

[proud basin]

@eternal oxide and 7smile7 I was talking to the devs that made NBT api and they said that it's not possible to do what im trying to do

[lost matrix]

Hibernate is there to abstract the queries away from you

[lost matrix]

F

[proud basin]

yeah

He said that plain file is slower than sql

Is that true?

[lost matrix]

No. It just scales worse.

[proud basin]

ah ok

So I guess im sticking to sql

[lost matrix]

I mean... Databeses have build in memory caches. So that why for repeated access they are in fact faster

But you can do the same with flat files.

[slow oyster]

Yeah, I've just been messing around with this class to achieve most of what I want https://paste.md-5.net/atejezoyer.java

[proud basin]

I guess ima have to deal with that delay I have

I think my query bad though

it takes longer than 10ms

[slow oyster]

10ms sounds good for an SQL query to me...

[lost matrix]

Def. And you shouldnt worry even if its 100ms. Just dont do any IO on the main thread.

[slow oyster]

Do you have an N+1 problem by any chance?

[lost matrix]

Looks nice. Now you just need to register some custom mappings and you are good to go.

[slow oyster]

I.e are you firing off a shit load of queries one after the other?

[proud basin]

no

[slow oyster]

So why is 10ms slow?

[proud basin]

I never said it was slow

[rose aspen]

Bumpy

[slow oyster]

Oh right, I thought you meant that SQL was your bottleneck

[proud basin]

Wait isn't there a way to check if its running on your main thread

[lost matrix]

What version are you on?

[rose aspen]

v1_17_R1

[worldly ingot]

Bukkit.isPrimaryThread() iirc

[proud basin]

ah ok thank you

wait where should I actually be running this?

[worldly ingot]

SQL? Off thread wherever possible. This is where CompletableFutures come in handy

[lost matrix]

I see you are using NMS. What do you need Protocollib for then?

[proud basin]

No Bukkit.isPrimaryThread()

What is CompletableFutures though?

ugh

why is the server crashing

[lost matrix]

As we told you yesterday. Really edge case method you will probably never use.
You first need to understand how to properly spawn a new thread, do something on it, and
sync back with the main thread when you are done.

[slow oyster]

Can you call Bukkit APIs inside a Future?

I presume not?

[lost matrix]

If they are on another thread then no. BukkitScheduler is thread safe tho.

[rose aspen]

I don't wan't to use NMS. I wan't to use ProtocolLib for this, but I really don't know how.
I took this example on the bottom https://github.com/dmulloy2/ProtocolLib/#sending-packets
So thats the way to send packets right.
But somehow it wont really work, as you see on my previous message xd

[proud basin]

Do you close the Connection first or PreparedStatement I forgot

[ivory sleet]

latter probably

[slow oyster]

I could probably extend CompleteableFuture and just make it call directly through BukkitScheduler then?

[ivory sleet]

why

[lost matrix]

You are already using NMS

[ivory sleet]

just wrap the bukkit scheduler into an executor and the pass that to the future?

[proud basin]

if Bukkit.isPrimaryThread() returns true that means its running on main thread correct

[ivory sleet]

ye

[proud basin]

ah shit

ok

[lost matrix]

Do you want to substitute what you have so far?
Because doing this purely with ProtocolLib will require you to do some nasty DataWatcher assembly.

[rose aspen]

If you mean EntityItem and CraftItemStack then yes.

But I want to do it with only ProtocolLib, I want to learn it.

[slow oyster]

It's late, you got an example of this? 😄

[ivory sleet]

well what exactly do you want?

[lost matrix]

This defeats the purpose of the CF.
What are you guys doing?

[slow oyster]

CF? I was just going to look at wrapping my queries to return Future's so that the queries can be run on a separate thread?

Oh completableFuture

[rose aspen]

Actually, I just want to know what I did wrong with my code, that somehow a particle appears instead of an item.

It can't be that difficult to somehow read that from https://wiki.vg/ and then use it?

[ivory sleet]

James then just use CompletableFuture#runAsync(command) and supplyAsync(supplier)

Or no?

Might wanna pass a custom executor actually

[slow oyster]

I suppose I want it to run on a separate thread and then I want the stuff in the future to be able to be run on the Bukkit thread

[ivory sleet]

Sure

[lost matrix]

Here is an example how you would load some data async and then apply an action to the data on the main thread.

  public CompletableFuture<PlayerData> applyToPlayerData(final UUID playerID, final Consumer<PlayerData> playerDataConsumer) {
    return CompletableFuture.supplyAsync(() -> {
      final File playerFile = getPlayerFile(playerID);
      final PlayerData playerData = readAndLoadPlayerData(playerFile);
      return playerData;
    }).thenAccept(playerData -> {
      Bukkit.getScheduler().runTask(SomePlugin.getInstance(), () -> playerDataConsumer.accept(playerData));
    });
  }

[ivory sleet]

Aww smile is fast as usually

[proud basin]

haha now its not running on the main thread

[slow oyster]

Okay cool, I suppose I can write a utility method that would return a Consumer directly from that method to be consumed in the BukkitScheduler

[lost matrix]

Ok thats how far im currently. This should be the proper way to prepare an Item packet. The metadata will be more complex tho.

  public void spawnItemWithProtocolLib(final ItemStack itemStack, final Location location) {
    final ThreadLocalRandom random = ThreadLocalRandom.current();

    final ProtocolManager manager = ProtocolLibrary.getProtocolManager();
    final PacketContainer itemPacket = manager.createPacket(Server.SPAWN_ENTITY);
    final PacketContainer metaPacket = manager.createPacket(Server.ENTITY_METADATA);

    final int entityID = random.nextInt();
    final int entityType = 41;
    final int extraData = 1;

    final StructureModifier<Integer> itemInts = itemPacket.getIntegers();
    itemInts.write(0, entityID);
    itemInts.write(1, entityType);
    itemInts.write(2, extraData);

    final StructureModifier<UUID> itemIDs = itemPacket.getUUIDs();
    itemIDs.write(0, UUID.randomUUID());

    final StructureModifier<Double> itemDoubles = itemPacket.getDoubles();
    itemDoubles.write(0, location.getX());
    itemDoubles.write(1, location.getY());
    itemDoubles.write(2, location.getZ());

  }

[opal sluice]

Hey guys, how would I check if a player is looking at a location

Like, getting the direction, and by the direction he can see the location

[lost matrix]

A Location is a very very tiny point. A player will almost never be looking at exactly one discrete location.

You can however easily find out what block the player is looking at by just using the ray trace method of Player

[opal sluice]

Yup, but I need to have this ray being able to tell me if it actually passes inside a "region"

Basically, like the hitboxes works

[rose aspen]

Wow! Thank you very much!
But where did you get the values entityType = 41; and extraData = 1; ?
From Spigot itself or by wiki.vg ?

Ah and by just using your snipped, it looks like this https://i.imgur.com/OUxtB9Z.png
(I looped this functions many times)

[quaint mantle]

Just go look at the client and gg you learned it

[rose aspen]

Looking at the client ? I've never done this before

[quaint mantle]

Yea you can get the client source and it has an implemented server

[rose aspen]

Ah okay

[lost arch]

Is this the right place to ask about plugin development? I’m looking to port my fabric mod.

[waxen plinth]

This is the channel for it, yes

[lost matrix]

From wiki.vg
41 is the entity id of Item

[lost arch]

How close are the APIs in terms of functionality?

[rose aspen]

Aha! From here so https://wiki.vg/Entity_metadata

[lost matrix]

But i have literally no idea why you see just a bunch of particles

[rose aspen]

Did you see an Item with your instance ?

If it helps idk

[lost matrix]

Now you will have to do something like this:

    final StructureModifier<Integer> metaInts = metaPacket.getIntegers();
    metaInts.write(0, entityID);    

    final WrappedDataWatcher watchableObjects = new WrappedDataWatcher();
    // Do some weird stuff here idk
    final StructureModifier<WrappedDataWatcher> metaDataWatcher = metaPacket.getDataWatcherModifier();
    metaDataWatcher.write(0, watchableObjects);

And fill the WrappedDataWatcher with stuff. But im not 100% sure. Maybe Plib has some separate wrapper for Items

[lost arch]

Is hot registering and unregistering commands possible?

[lost matrix]

Yes

[lost arch]

In Fabric you have direct access to brigadier

[lost matrix]

But you usually dont want to do that

[lost matrix]

You can also gain direct access to brigadier in spigot. Just not with the API.

[lost arch]

Is there a spigot equivalent to mixin? My mod cancels methods.

[lost matrix]

What do you mean by "cancels methods"?
Spigot has a command framework.

If you want to do bytecode injection then you need to shade that in yourself.

[lost arch]

In fabric I can inject into a Minecraft method and then return from that

Yeah

Wdym shade it in?

[lost matrix]

Use your dependency manager (maven or gradle) and provide an injection library like ASM with your plugin.

So shade the library into your plugin.

[proud basin]

How bad of performance can you lose from getting a value from your sql db if it's on the main thread?

[lost matrix]

To the point where your server just crashes

[proud basin]

Is there a reason why my server isn't crashing?

[lost matrix]

You didnt encounter any problems with your DB so far and you probably dont stress test the DB to simulate what would happen with multiple users online.

[proud basin]

right

So when your connecting to the db do you still not want to be on the main thread?

[lost matrix]

If you DB (or your hard drive) is busy then the main thread will just wait (worst case) several seconds for a response.
In this time nothing on the server will function. Every user will stand still, every entity will stand still, nothing falls moves or flows. The server is just dead for that time.

[unreal quartz]

worst case scenario using default values you could be waiting 30 seconds for a connection timeout

by that time all your players have been disconnected

[proud basin]

hm ok

[lost matrix]

A connection can fail and take some time to recover

[proud basin]

Is there different threads to let me return a long?

[lost matrix]

If you start a new thread then you wont get anything from the thread right away. You just tell the thread to do something and then move on.

[proud basin]

right

but

wait do I just need to put the connection in a new thread?

Sorry I'm just trying to understand this

[quaint mantle]

It’s just locking, so your main thread gets frozen until it’s no longer locked

[lost matrix]

Multithreading is a pretty complex topic. Ill draw you a quick diagram that shows how the threadflow in spigot works

[proud basin]

ok

[quaint mantle]

Look just run your stuff with a bukkit runnable async.

You’re better off with that for now

[proud basin]

But then I gotta redo everything

[lost matrix]

Ok so Minecraft is a tick based game.
Every 50ms a new tick begins.
First Minecrafts core mechanics will be applied. All mobs will be ticked. Packets will be prepared and read. Chunks will be loaded etc. This consumes the first 10, 20, 30 ms
Then there is some Spigot stuff happening. Event handling. Runnables will be executed etc. This lasts another lets say 5ms.
Now you have maybe 25ms to waste with your plugins code. If you start a query that lasts longer than 25ms then the next tick has to be delayed. This results in fewer ticks per second being scheduled.
(1000ms / 50ms = 20(ticks) but if a tick lasts 60ms on avg then 1000ms / 60ms = 16,66(ticks))
@proud basin

[lost matrix]

But i most cases you dont need to do complicated stuff like this.
You can always listen for the AsyncPlayerPreLoginEvent which is async on default and just load all the player specific data there into memory.
Then just work with the data in memory.
Then listen for the PlayerQuitEvent and save the player specific data back into your DB using the BukkitScheduler.runTaskAsync(...)

hello, it is I, magmaguy, master of java programming here to teach the people who make java how to make java better

lads, you have instanceof, give me notinstanceof

[lost matrix]

!(X instancof Y)

lul

[torn shuttle]

every time I do (!(a instanceof b)) a fragment of my soul exits through my ass

[lost matrix]

But i get you. Ive always wanted something like that because the brackets are tedious

[torn shuttle]

hell

I'll even take a !instanceof b

[lost matrix]

Same. But that would violate the syntax

[torn shuttle]

yes but not having it violates my soul

[lost matrix]

XD

[torn shuttle]

anyway thanks for coming to my tedx talk, you can purchase my book "how java ruined my soul" on your way out for $45

[hasty prawn]

Is it signed?

[torn shuttle]

you can pay an additional $20 for the signature

[hasty prawn]

deal.

[torn shuttle]

sure just paypal me the $65 and I'll send you a copy

[worldly ingot]

I'd take a !instanceof too

Oracle pls

[torn shuttle]

you know what I've not checked at all but I bet c# has a way to deal with this that is entirely seamless

[lost matrix]

Just write an email to the oracle HQ notinstanceof when?

[worldly ingot]

I don't actually think it does, Magma

iirc it too uses !(value instanceof whatever)

[torn shuttle]

java is like the lame stepfather who hits you with a belt when you try to put on your hat backwards and c# is the cool dad who picks up your friend in a convertible while blasting russian hardbass

[worldly ingot]

Oh it's is in C#. Sorry. Haven't done much C# in a while

[proud basin]

so I I'm trying to do it the complicated way?

[lost matrix]

if(C is not typeOf(D)) {

}

[worldly ingot]

But yeah, same issue

oh fuck off, they just added is not in 9.0 lol
https://devblogs.microsoft.com/dotnet/welcome-to-c-9-0/#logical-patterns

hm seeming obj is MyClass is valid syntax

so

[cold tartan]

how do u get the paper api?

[torn shuttle]

I mean sure he'll be in a car wreck one of these days but it will be a cool car wreck and he probably will have a dashcam

[lost matrix]

Ask on the paper discord

[worldly ingot]

Well you're definitely in the wrong server, burger lol

[cold tartan]

oh crap ya lol

[torn shuttle]

C# is lit and once I start using it for unity I will probably never really come back to java

[lost matrix]

I actually have no idea what you are currently doing. I was just rumbling about threads...

[proud basin]

ah ok

so I think I am actually doing it completely wrong

[lost matrix]

Eh you probably will. Microsoft Javas popularity is declining. Also Minecraft...

[lost matrix]

No no. I just dont know what you are actually doing XD

[lost matrix]

Where dog?

[torn shuttle]

I'm not beholden to following the trends

for the foreseeable future I have the liberty of choosing which programming language I want to use

[worldly ingot]

Definitely overcomplicating that because Bukkit's scheduler will suffice for that

[lost matrix]

You will come by all of them. At least C++, Python and JavaScript

[hasty prawn]

Python 🤮

[torn shuttle]

I don't really see why I'd ever bother with python

[worldly ingot]

Bukkit.getScheduler().runTaskAsync(plugin, () -> {
    // Do your SQL stuff in here. No need for the Thread creation
});```

[torn shuttle]

unless it really changes in the future

[lost matrix]

https://tenor.com/view/kevin-the-office-why-say-lot-word-few-word-do-trick-gif-16426767

[proud basin]

ah ok so I did it completely wrong

[lost matrix]

In some industries getting stuff done quickly with scripts is more important than maintainability

[worldly ingot]

Not completely wrong. What you wrote works fine, just no reason to start the thread yourself when Bukkit supplies you with a thread pool

[torn shuttle]

well if things go right I won't need to worry about that

[lost matrix]

Not completely wrong. Just overcomplicated.

[lost arch]

Few words go slow

[proud basin]

ah

[lost matrix]

Unless there is a library in the background that uses C for the hard lifting. But yes. (pure) Python is really slow.

[hasty prawn]

It's also super ugly imo

Having indentation matter is

:(

[torn shuttle]

for some reason every time I see a python program is seems to be made to just process some math and maybe make some graphics

just lots of number crunching

[lost matrix]

You should probably follow the routine ive described earlier.

1. Load the Data from a DB in the AsyncPlayerPreLoginEvent
2. Use the data in memory (so a Map for example)
3. Save the data back when the player quits (PlayerQuitEvent) then you can just use an async task from bukkit

So you dont have to constantly tinker with multithreading or async tasks.

[proud basin]

hm

[proud basin]

but why would I load the data whenever someone joins?

[lost matrix]

Because you only need a players cooldown when he is actually online, right?

[proud basin]

What if the command /reload was used?

[lost matrix]

Then you tell the person that used the command that it is not supported by anyone and he should not use it.

[proud basin]

But it's such a useful command

[lost matrix]

But you can just iterate over all online users on onEnable() and onDisable() to load/unload the data on reaload.

[proud basin]

I guess

[lost matrix]

No its an evil command that nobody should use. Even spigot discourages the usage of this command.

[proud basin]

Then why did they add it?

[lost matrix]

They didnt

[proud basin]

mojang did

[lost matrix]

I think its a bukkit command

[proud basin]

uh

I believe its in vanilla

although haven't touched vanilla in a long long time

[lost arch]

Can I cancel chat from going through to other players in a spigot plugin?

[lost matrix]

Anyways. You can support reloads by saving all online player data onDisable() and load all online player data onEnable()

[lost matrix]

Yes. You can change the recipients of a Message by simply listening for the chat event.

[proud basin]

alright

[proud basin]

Time to achieve this

[lost matrix]

But if you want to cancel messages from other plugins then you would need to listen for the outgoing chat packets.

Which is done using a library called ProtocolLib

[lost arch]

Cool beans, another question, can I run commands from a plugin or run Minecraft methods?

[lost matrix]

It injects a packet handler into the netty pipeline

[maiden thicket]

bukkit.dispatchcommand(CommandSender, String)

[lost arch]

Thx

[proud basin]

Would I use this in the asyncPlayerPreLogin

[maiden thicket]

u cant run client methods from mc but u can run nms methods from the net.minecraft.server package

[lost matrix]

You can force a CommandSender (including the console) to dispatch a command.

[maiden thicket]

in order to do that u have to use buildtools and compile spigot

[lost arch]

Can I capture server console log output?

[lost matrix]

Uhm. Sure. Its just a simple PrintStream

[lost arch]

This is my fabric mod by the way if you’re wondering why I’m asking about this random stuff https://GitHub.com/CamelBot/CamelMod

[proud basin]

bump to you

[maiden thicket]

or that

[lost matrix]

Ah. Yes. Thats the right event. You dont need to do anything special here other than loading the data.

[proud basin]

ok so I don't need the scheduler

[lost matrix]

Nope. Just load the data right there. The event is already async. So stuff you call in this event wont be on the main thread.

[proud basin]

ok

[opal sluice]

Does someone know what's the math to calculate if a vector does intersect a plane ?

[proud basin]

I think im gonna have to use getter and setters

well actually I don't

but

[lost matrix]

Sure. But why do you need that? In most cases you dont need something so low level in spigot.

[proud basin]

Alright the asyncpalyerprelogin is event is done

[opal sluice]

Cause I'm trying to dev a custom hitbox system that need to know if the player is actually looking at the hitbox

[void haven]

Hello I need help with Bungee

[proud basin]

Step 1 is completed

[lost matrix]

Use the build in BoundingBox class from spigot for that.

[opal sluice]

Yeah, but that's a box

[torn shuttle]

say you have class A then class B extends class A then class C extends class B , and they all have a #remove() method which gets more complex as you go down, is the correct solution to override and then have a non-overwritten helper method that contains the logic for the #remove method so you don't just copy paste code from class to extended class?

[lost matrix]

And you want an octahedron?

[torn shuttle]

it feels sort of dumb

[opal sluice]

Any kind of shape

[proud basin]

Would I want to load all of their data including uuid, time and cooldown

[void haven]

I need help with bungee!

[lost matrix]

Ok then be prepared for some ridiculous amount of math. Calculating the intersection of a vector and an arbitrary shape is complex.

[lost matrix]

Yes. All the data that is related to this player.

[opal sluice]

I was thinking of getting all the shape's planes (from the shape's coordinates) and then calculate if the vector does intersect one of the planes

Which would result in the player looking at the shape (I guess)

[torn shuttle]

ideas for my polymorphistic nightmare?

[lost matrix]

This means your method linearly scales with the amount of planes in the shape. Which is bad.

Would be O(n) yeah

[void haven]

I have this command panel, When I do ./server [name] it works but not in the panel

name "Command Pannel"

[lost matrix]

State of the art vector intersection is done using ray marching.

[silk mirage]

command panel?

[void haven]

yes the plugin

[torn shuttle]

ray tracing but implemented by the army?

[silk mirage]

Is that a bungeecord plugin?

[silk mirage]

^

[lost matrix]

https://ch-st.de/its-ray-marching-march/

[torn shuttle]

I'm looking at raymarching already lol

I feel like I half remember this

[void haven]

no

[lost matrix]

No. You overwrite like this:

@Override
public void remove() {
  super.remove();
  // Do your new stuff here
}

[torn shuttle]

hoh

dumb

[lost matrix]

This calls remove from the super class before it runs other code

[torn shuttle]

man I even did that in other parts of my plugin, I need to go get some more coffee

thanks

man I am doing some stupid shit today

[void haven]

So i have to install it in my bungee for it to work aswell? @silk mirage

[lost matrix]

Ok so you want to support intersection of non cubic shapes in a voxel based game. Why?

[silk mirage]

are u using bungeecord message system OR what r u doing

[opal sluice]

Because, people do make custom models, and those are not always cubic

[lost matrix]

A fixed set of shapes? Or even custom shapes imported from something like blender

[opal sluice]

Imagine having a dragon, with a proper hitbox that is shaped as the dragon

[lost matrix]

Can be done with a bunch of cubes

[dusk flicker]

Has anyone had problems with the maven shade plugin not working on Java 16?

Cant seem to get mine to shade anything in with an unsupported class ver of 60 error

[silk mirage]

add <target>

wait

it was like

[lost matrix]

Not so far. I dont think the java version should affect your maven dm.

[opal sluice]

Well, it would still be a custom shape since it requires multiple cubes

[silk mirage]

compiler target

[dusk flicker]

I have maven.compiler.target in the properties set to 16

[lost matrix]

Also set the source to 16 and see if that helps

[dusk flicker]

I have that aswell

My shade plugin is ver 3.2.4 and that's the latest ive seen

[silk mirage]

it shall be bcz shaded library were built with java version less than 16

[lost matrix]

That should be no problem

[lost matrix]

Is it a compile time error?

[dusk flicker]

It's when I run mvn clean install

[lost matrix]

Ah. Then make sure maven properly recognises your installed java version.

[torn shuttle]

oh that's interesting, so it's like raytracing's roundboi friend

[void haven]

?

[silk mirage]

send the part of the code

that is not working

[lost matrix]

Are you developing a plugin?

[dusk flicker]

mvn --version is showing it just fine, I just reran it now and removing one of my configs under the shading system seems to fix that problem but another one has popped up that i'm looking into now

[void haven]

No

It’s a plug-in

[lost matrix]

Then this is the wrong channel

[void haven]

Named command panel

[lost matrix]

#help-server

[torn shuttle]

so is non-spherical raymarching faster than ray tracing in general and then sphere tracing would only be faster in very specific contexts?

sphere tracing sounds like a technique someone would've used back in the ps2 era in order to squeeze more juice out of the hardware but still have a form of tracing

[quaint mantle]

I know this thing has been fixed for ages: https://bugs.mojang.com/browse/MC-106202 but was the fix only on the chest block glitching out?
if so do you think it would still be possible to open a chest with a 3 chest layout?

[lost matrix]

You can do it via code for sure

[dusk flicker]

This was the problem, one of my dependencies in another package were out of date

[quaint mantle]

I had an idea of how this could be utilized but yeah idk if you really can open the gui with a triple layout, I have not looked into it at all so I really don't know anything about it

[lost matrix]

Huh? Java versions are backwards compatible.

[torn shuttle]

you know what I'm going to implement sphere tracing on my plugin just for the hell of it

[dusk flicker]

It was a lombok err due to compiler changes

[quaint mantle]

I just remembered this old bug and got an idea out of it so it would be cool to get it working

[torn shuttle]

you should probably be asking that on the worldedit discord

[quaint mantle]

I am sure I would have to send packets myself for this though right? everything that is exposed in the api probably if not definitely doesn't allow it

[torn shuttle]

then you have your answer

sure it's possible

anything is possible if you have an infinite amount of time

there's probably a way to do it using reflections

[lost matrix]

Hm... just realised that they patched the possibility of just using a normal inventory out.

[torn shuttle]

https://www.spigotmc.org/threads/tutorial-writen-how-to-use-reflection.41413/

[quaint mantle]

that's sad, which version was that patched in?

[lost matrix]

It means that you basically scan the actual class file instead of getting the information from the runtime.
So you can change stuff you are normally not supposed to even see.

[lost matrix]

🤷

[torn shuttle]

reason why it gets mentioned so much is because it and nms are the only ways of doing some pretty crucial stuff

cough pathfindergoals cough

[quaint mantle]

just read thru some patch notes on the bug and it seems as if the actual gui problem wasn't ever actually fixed, the only thing that was fixed was the chest bug that allowed it

[lost matrix]

Im currently digging in NMS but it doesnt look too good because even when i bypass the spigot check i get:

[quaint mantle]

yeah I see

what happens if you try setting exactly the 3 chest size? so 81

[lost matrix]

The same

[quaint mantle]

hmm

I guess it was patched in some way then in the CraftContainer

[lost matrix]

I tried going down to 7 * 9 which is one row more that usual

[lost matrix]

Nope it goes even deeper. In NMS there is one static final instance for every container size

[quaint mantle]

oh lmao

that wasn't like that before was it?

[lost matrix]

Nope. Im pretty sure that when im going to try and tinker a new version of this container with 9x9 slots the client would just crash.

[proud basin]

So I managed to get the list of columns but how could I just get the rows from those columns (sql)

[quaint mantle]

hmm idk if it would crash as it was able to render that container but yeah I guess I see your point as those are set like that

[lost matrix]

I can maybe try tomorrow with some reflection and a lot of optimism to assemble a container with that size

but im out for today

[quaint mantle]

yeah no worries man, if you have some spare time and get to do it @ me please I am curious lmao

cya

[cold tartan]

could someone help me with this:
https://paste.md-5.net/oyezafiyoj.md
it has an issue with NBT API
but i added it to maven and regenerated it

oh wait

found it

forgot to add the plugin to my plugins folder

[opal sluice]

Does someone has the bit of code where the damages are calculated ?

[quaint mantle]

Explain?

[opal sluice]

I would like to know the damage a player would do if he hits something WITHOUT hitting something

[dusk flicker]

Likle you want to damage someone?

[quaint mantle]

just for reference so you have it
I have done some testing now but I really can't get past some things as I really didn't mess with most of this stuff

but yeah container sizes are checked in some ways so maybe you could do something with reflection idk

[opal sluice]

Like, I would like to know, when a player hits the air for example, what would be the damage done if it wasn't air but an entity

[paper geyser]

any clue why i'm getting sent this?

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

code: https://paste.md-5.net/imasijakib.java

https://paste.md-5.net/ucilikotes.sql is looping over and over

[hasty prawn]

Is this what you're trying to do?

[opal sluice]

at com.mcbt.rpgpackets.Slimeinswamp.SlimeReplace(Slimeinswamp.java:29) ~[?:?]

[paper geyser]

ahh

forgot to notate that

Entity ent = Bukkit.getWorld("rpg").spawnEntity(event.getLocation(), EntityType.SLIME);

what is the issue with this

[hasty prawn]

Does the world "rpg" exist

[paper geyser]

yes

[opal sluice]

Send the full error pls

[hasty prawn]

^

[paper geyser]

alright

[quaint mantle]

indeed

[hasty prawn]

Hm, lemme see if I can find anything

[paper geyser]

alright it took a bit of effort to get a latest.log that isn't so big that I cant save it to the hastebin but here it is

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

[hasty prawn]

Oh, spawnEntity is calling SlimeReplace(EntitySpawnEvent), so it's infinitely looping

[paper geyser]

hmm

how would I work around this?

I thought my if (event.getEntity().getType() != EntityType.SLIME || event.getEntity().getType() != EntityType.PLAYER || event.getEntity().getType() != EntityType.DROPPED_ITEM) { would cover that

WAIT

IT SHOULD BE =

NOT !=

or

hmm

it should be .equals not == right/

hmm

wait no

ahh i got it nvm

[quaint mantle]

if you do @ me please :)

[hasty prawn]

👍

[quaint mantle]

also just referring to this screenshot, it's saying container size 41 is smaller than expected as I was passing the playerInventory in the iinventory part so yeah

[hasty prawn]

This is terribly confusing the way they've done this ngl

[lost arch]

Is spigot built on top of vanilla or is it completely reprogrammed from the protocol?

[hardy swan]

You realise that this is always true right

[paper geyser]

I figured it out

yeah

did this instead

            if (event.getEntity().getType() == (EntityType.SLIME)) {
                return;
            }
            event.setCancelled(true);```

silly mistake haha

thanks for scrolling up and still trying to help though! Appreciate it

[hardy swan]

isn't this whole thing the same as

if (event.getEntity().getType() != EntityType.SLIME) {
  setCancelled(true);
}

or is there sth else you are doing before the second if

[paper geyser]

its actually after, I replace the entity with a slime

[quaint mantle]

How to check if offlineplayer exists?

[paper geyser]

wait

hmm

[paper geyser]

I did have this section as part of my code but it did loop

    public void SlimeReplace(EntitySpawnEvent event) {
        if (event.getEntity().getType() != EntityType.SLIME || event.getEntity().getType() != EntityType.PLAYER || event.getEntity().getType() != EntityType.DROPPED_ITEM) {
            event.setCancelled(true);
            if (event.getLocation().getWorld() == Bukkit.getWorld("rpg")) {
                Location center = new Location(Bukkit.getWorld("rpg"), 68, 69, 125);
                Double distance = 75D;
                Location location = event.getLocation();
                if (location.distanceSquared(center) <= distance * distance) {
                    Entity ent = Bukkit.getWorld("rpg").spawnEntity(event.getLocation(), EntityType.SLIME);
                    Slime slime = (Slime) ent;

                }
            }
        }
    }
}
``` this code was giving the error which does have that

plus other stuff

[hardy swan]

no what im saying is

[hardy swan]

your first if statement is still useless

suppose A || B but ~A -> B, then A || B is always true

Before I begin, this idea has come from me experimenting with numerous plugins as I plan my server to death. Real shoutout to @NoLogic with his Vivaldi plugin for what I feel is the best seasons plugin out there right now. Now here we go!

Using a secondary world(s) to simulate seasons in Minecraft

To my understanding a plugin should have the capability of modifying blocks, tracking movement, altering game states/rules, force texture packs, alter files, and enabling chunks.

What should be possible to simulate seasons without seriously altering biomes or being global projections across the server while also controlling good tps for a immersive world, this would give the most controlling form of seasonal support in vanilla Minecraft. It plays as this, a world (A) is generated with another world (B) that should be exactly the same. World A serves as one season, most likely summer. World B serves as a winter variation of the world.

The worlds both A and B will be generated by seed if the server is just normal Minecraft. If using custom maps World A would be generated with whatever features (new generation or custom map) then copied to world B. (raw region files for optimization). This second option would most likely be the optimal way to do it even if its vanilla Minecraft seed generation.

Next, we alter World B to be winter. This is done by having a loaded chunk alternate through the world checking ever chunk. This is while the server would be offline from player use, in server setup or when setting up this plugin or to play catch up on the following functions. World B is modified using functions to modify blocks so that (based on biome type, an uploaded image map, or coordinate/height-based settings) So that regions are snow covered, and water now ice.

Now we have world A in summer and world B in Winter. Hit the start button and players join. These players actions will be tracked in the following way to keep world B synced to world A. Real time editing could be enabled so that new blocks made or destroyed are detected including all attributes such as generation, changes in block states, items in chests, accounting for seasonal variation etc) and is copied into a currently FROZEN world B. world B should be programmed where the only block changes made can be done by this interaction between World A and B. Functionally World B is dead. It will have world game rules to disable for example natural decay of snow in the winter world even in say a desert. If tps becomes an issue, the changes could be saved to a file that will chronologically act it out in World B when server tps improves or set up for a maintenance.

Winter approaches and the server now must load world B and unload A. In this process it tells the server to use a winter version resource pack instead of vanilla summer or unloaded one. The plugin also updates all player locations in world B to match world A. Server reboots, players join and now are in a winter tone of their world where the texture pack with optifiine would be used to solve ambience, textures, biome colors, rain to snow based on biome, sound, you name it) to account for the visual aspect, so that it snow in a plains biome that has been altered to be covered in snow.

Pros to this: With techniques to minimize server resources when making the opposite variation world or worlds, players can enjoy exploring without lag. Then they can explore complete chunks that are already loaded into another seasonal type. This is due to the pre scan of making seasonal affects across an entire world before the server starts up and having a function that when new chunks are generated load additional resources to make it seasonal type of the current world a player is in, adding a layer to current world gen (which can be copied to the other worlds later).

The downsides is players would be forced to use a resource pack and the server would be down between seasons for a restart. .

Thoughts?

[quaint mantle]

ehm… why?

having 4 worlds that are exactly the same is not minimizing resources

also instead of using 4 worlds you could just fake biomes for snowing and stuff like that

but creating 4 worlds that would need to be constantly updated for changes will definitely cause issues

player.openInventory(craftingInventory);````aused by: java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_15_R1.inventory.CraftInventoryCustom cannot be cast to class org.bukkit.inventory.CraftingInventory (org.bukkit.craftbukkit.v1_15_R1.inventory.CraftInventoryCustom and org.bukkit.inventory.CraftingInventory are in unnamed module of loader 'app')`

[digital plinth]

that returns CraftInventoryView and is not the same as a inventory

[digital plinth]

different classes

CraftInventoryCustom

and

CraftingInventory

org.bukkit.craftbukkit.v1_15_R1.inventory.CraftInventoryCustom

is this nms?

weird name

so you want to set a recipe on the workbench when a player opens a workbench with right click or with a command?

[quaint mantle]

hnmm

[quaint mantle]

nop

when player right clicks book

open workbench, set result of item and metric

[quaint mantle]

uhh is there no solution? 😦

[digital plinth]

its is totally doable

[granite stirrup]

anyone know the best way to convert a HashMap's values into a List

[digital plinth]

i think

[digital plinth]

.toList

lol

googl

[granite stirrup]

its not a thing?

[digital plinth]

hashmap is a map

they are different?

list cant store keys and values

[quaint mantle]

can you tell me the solution?

I can't find any google result or thread

[granite stirrup]

i dont want to store the keys tho i just want to store the values

i want to put them into a list

[digital plinth]

.values?

[granite stirrup]

intellij gave me this lmao ArrayList<>(myHashMap.values())

for some reason

[digital plinth]

i dont quite understand java collection tbh

[quaint mantle]

bump

[granite stirrup]

apparently ArrayList<>(myHashMap.values()) this is a arraylist constructor?

it should work right ?

[quaint mantle]

Still trying to figure out how to cancel the bow pulling

like its possible

but idk how

[granite stirrup]

pretty sure theres a event for that

[digital plinth]

right click?

check for bow

cancel

?

bow pulling

not bow shoot

[quaint mantle]

I already cancelled the interact event

[digital plinth]

oh

[quaint mantle]

but that just prevents it from shooting

[digital plinth]

packets

[quaint mantle]

its still draws/pulls back the bow

[quaint mantle]

ye but wich xD

[digital plinth]

its client sided hmmm

[digital plinth]

no idea

ask in protocalLib discord

[summer scroll]

I have do some testing and come up with this.

InventoryView inventoryView = player.openWorkbench(null, true);

CraftingInventory craftingInventory = (CraftingInventory) inventoryView.getTopInventory();
craftingInventory.setResult(new ItemStack(Material.BARRIER));
player.updateInventory();

and it works, it set the result and you need to update the inventory otherwise you will got a visual bug.

[summer scroll]

what are you trying to do?

[quaint mantle]

does anyone have a link to protocol Lib discord?

[granite stirrup]

just to convert the values of a hashmap to a ArrayList

[summer scroll]

Oh, Map#values then

[granite stirrup]

yeah ik i was messing around and intellij gave me that

[quaint mantle]

uhh

removed the snapshot part and it works

i cant find the discord for protocolLib

[summer scroll]

bro, just go to their resource page on spigot
