[fresh timber]

also if arrow despawns, will this info be deleted?

[lost matrix]

It wont slow your server and if an entity despawns then its whole data will ofc be deleted

[fresh timber]

alr

tysm

how do you get the projectile or arrow entity that was in the air before in an EntityDamageByEntityEvent?

[lost matrix]

getAttacker()

[fresh timber]

thats the player right

[lost matrix]

-> then check if instanceof Projectile

[fresh timber]

ah

[lost matrix]

The attacker will be the arrow entity

[fresh timber]

oh event.getAttacker() is not a thing

[lost matrix]

Wrong event

[fresh timber]

hm?

[lost matrix]

EntityDamageByEntityEvent not EntityDamageEvent

[fresh timber]

thats the one im in

[lost matrix]

Ah getDamager()

[fresh timber]

so if I checked before if the cause is damagecause projectile do I still needa check if the damager is instance of projectile

or just getdamager

[lost matrix]

Yes. Only check with instanceof

[fresh timber]

alr

so if getdamager is the entity projectile, what is the player that attacked you

or are they the same..

[twilit wharf]

Not sure if this is the right place for this, but I am making a chess plugin, and I am curious how I can go about making a full sized board (8x8). I am using the unicode system for the icons and textures. Does anyone know of a way to allow the player to easily control every piece from the menu, and not external commands?

[lost matrix]

Where is this chess board located? In an inventory? On Blocks? On a Map? In Chat?

[fresh timber]

How do you get the player that attacked in an entitydamagebyentity event if getdamager is the projectile?

[twilit wharf]

sorry, I forgot to mention that it is in a inventory. (or at least that is what it is right now, not sure if there is a better way)

[terse pumice]

Would anyone happen to know how to get a specific light block (eg. light level 12) as an ItemStack?
Unsure if this information is useful but this is the command to give it: /minecraft:give Dav_e_ light{BlockStateTag:{level:"14"}} 1

[lost matrix]

Well then clicking the figures is the way to go. Properly displaying them is a bit harder.
You can try custom textured heads.

[twilit wharf]

but that doesnt change the issue of the inventory being 9x5 and the chess board being 8x8

[lost matrix]

Ah i see the problem... Well nothing you can do there.

[twilit wharf]

I know it is possible, I just don't know how. I saw someone use an entire screen worth of space and have everything clickable (no mods, vanilla and a resource pack). They mentioned it involved core shaders.

[fresh timber]

make chess thing not in inv

like on ground or smthin

[lost matrix]

Some meh ideas:

• make the inventory scrollable
• Use the players inventory as well

[twilit wharf]

Someone managed to make something like this, with the whole thing interactable. Like I said above, this was done with core shaders (which I have no clue how or even what they do)

[fresh timber]

o.o

I wonder whow much work that took

[twilit wharf]

They act like it took no work at all.

[fresh timber]

tf..

[twilit wharf]

I can share the link to their discord, there is a bunch of cool things like that on there.

[lost matrix]

For that you need custom resourcepacks

[twilit wharf]

I mentioned that I am using that

with the unicode system and all

[lost matrix]

Well you can abstract quite a bit away. Programmatically this is not too much work.
Most of the work lays in drawing the textures.

[twilit wharf]

Well, I just don't understand the actual concept behind it. If I knew how it worked and how it could be replicated, then I could work out the drawing and stuff later.

[lost matrix]

Well if you use a resourcepack then you can just create a 9x6 inventory, use the players inventory as well (3 rows) and
use a replaced inventory name as a chess board texture. The pieces can be actual ItemStacks.

[twilit wharf]

hmm

[lost matrix]

Any sources for this?

[twilit wharf]

https://discord.gg/9r4SPzZz

not sure if discord links are allowed here, but that is the invite to the discord

[lost matrix]

With just a renamed inventory you can do a lot:

[twilit wharf]

I know how to do all of that

That isnt the issue.

[lost matrix]

What is the issue then?

[twilit wharf]

I just wanted to know if there was a way to get an interactable gui bigger than a regular inventory, since obviously others have been able to achieve that.

and if I use the player's inventory, then I get the Inventory text and the gap where it isnt interactable, which wouldn't be very pretty in production.

[winged anvil]

holy pretty

[twilit wharf]

yep

[winged anvil]

bedrock or java?

[twilit wharf]

Java

[lost matrix]

Honestly i couldnt figure out how they did this by now. What informations do we have?

[twilit wharf]

nothing. I contacted the guy and all he told me was it was core shaders.

he didnt say anything more, and I didn't feel like being pushy was the right way to go.

they obviously werent directly stating how they were doing things, and that is probably from a business standpoint. If you let your competitors know how your entire business operates, what stops someone with more resources from out pacing you and stealing your marketshare.

[lost matrix]

Yeah the shader part i understand. Those are just some opengl shaders.
But how are they registering the clicks?

[twilit wharf]

yeah, I got no clue.

[winged anvil]

oh damn each button is actually its own button and not like a collection of slots?

this would be fire if we could figure it out cause id be able to make everything ive wanted to in terms of ui

[lost matrix]

Let me take a look at the protocol... Maybe there is some packet which sends screen space locations.

[trim lake]

Im making anvil rename gui, how to remove cost of rename? I tried this:

@EventHandler
    public void handleMenu(InventoryClickEvent e) {
        Player p = (Player) e.getWhoClicked();
        AnvilInventory anvilInv = (AnvilInventory) e.getInventory();
        anvilInv.setRepairCost(0);
        if (e.getSlot() == 2) {
            //ItemStack item = e.getCurrentItem();
            ItemStack item = anvilInv.getItem(2);
            String newName = item.getItemMeta().getDisplayName();
            FactionRankUtils.rename(faction, rank, newName);
            p.closeInventory();
            p.sendMessage(ChatUtils.format("&aÚspešne si premenoval rank &e" + rank + " &ana &e" + newName + "&a."));
            return;
        }
        p.sendMessage("Slot: " + e.getSlot());
    }```

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/AnvilInventory.html#setRepairCost(int)

In the PrepareAnvilEvent

[trim lake]

Oh, I cannot do that in InventoryClickEvent? daaam, that's complication 😄 So, chatGPT is dump 😄 I tried that (ChatGPT) to create this GUI, and it suggest me to do that in InventoryClickEvent.

[trim lake]

Thank, I will take a look on that

[trim lake]

Hmmm, event is not called with custom anvil inventory. But, if I clicked on anvil and start renaming some item is working. Any ideas?

Im using this to create and open inventory, mby thats a issiue?

Inventory inv =  Bukkit.createInventory(this, InventoryType.ANVIL, ChatUtils.format(getTitle()));

player.openInventory(inv);

[frank kettle]

So far every answer on chatgpt I've seen is wrong

It somehow looks correct but something or multiple things are always wrong.

[trim lake]

Ye, I just want to try that and save me time on google 😄 but.. better to google thinks

Any ideas why is PrepareAnvilEvent not called with custom inventory?

[wet breach]

Bigger in what way?

As in more slots?

[lost matrix]

We where speaking about how interaction in this is handled:
#help-development message

[rough basin]

Why unstackable items get stacked when I use reload

[lost matrix]

[rough basin]

Damn need translation app

Wait a sec

[lost matrix]

First of all: never use reload. It breaks half the plugins

[rough basin]

almost everyone said and its true, but why this happens?

nah ignore me, will be return with more info

[wet breach]

Is that entire bottom row interactable? Doesnt appear so

If not then getting the sides to display like that isnt hard if we are not worried about interacting with it

[lost matrix]

You might have a point. Maybe its just visual

[lost matrix]

But what about this one
https://cdn.discordapp.com/attachments/1064182580569722981/1066805287459225640/image.png

A chess board has 8x8 tiles. How can this fit in an inventory...

[wet breach]

You would use two inventories with custom textures to hide that sliver.

[lost matrix]

I thought 6x9 inventories arent possible anymore. So there would be a gap between top and bottom inv

[wet breach]

The gap is visual only

So you would just use a custom texture to remove the gap

But player inventory and double chest inventory has enough rows and slots for a chess board

[lost matrix]

This gap doesnt look visual-only to me

[wet breach]

This is where the shaders come in. Smoosh the graphic enough and its gone

[lost matrix]

I know that in earlier versions you could create one more row which would create a seemles big inventory

Never call anything main

[wet breach]

Recommended to name it after your plugin or related

You only name it main if its the main class of the entire program

[lost matrix]

Even then you would go for something like Application

[wet breach]

Well i wasnt counting plugins as programs exception being ones that can run standalone in which case application is more fitting

Those are typically called manager classes. But for plugins typically your main class is named after the plugin or a short name variant if its a long name lol

[wet breach]

This weekend i will look at the code. It might still be possible to add that extra row just buried or something that it doesnt make it really feasible to have the api do it for you like previously

Been needing to decompile the client anyways as well

[worldly ingot]

AbstractManagerFactorySupplier (/s)

[lost matrix]

DataFixerUpper.function10

[twilit wharf]

Everything

[twilit wharf]

Sounds good, let me know what you find. I will continue looking into this as well.

[lost matrix]

Well... Its a decent troll.

if player is in survival -> put him in creative
else -> put him in survival

Thats the short form of your code

This will break console commands

Blindly casing CommandSender to Player

Yes

Sure if it helps you learn then go for it.

Also: You fool nobody with your new name Bettanation 😅

[wet breach]

Sure thing

[left plover]

What about a default case?

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String alias, String[] args) {
        Player p = (Player) sender;
        if (sender instanceof Player) {
            if (p.isOp() && cmd.getName().equalsIgnoreCase("/gmswitch")) {
                switch (p.getGameMode()) {
                    case SURVIVAL:
                        p.setGameMode(GameMode.CREATIVE);
                        break;
                    default:
                        p.setGameMode(GameMode.SURVIVAL);
                        break;
                }
            }
        }
        return true;
    }

[tender shard]

why are you manually checking the command's name? also it'll never be equal to "/gmswitch" unless the player entered "//gmswitch"

also you should use proper variable names instead of "p"

also why do you have 3 times the same case?

                    case ADVENTURE:
                    case CREATIVE:
                    case SPECTATOR:
                        p.setGameMode(GameMode.SURVIVAL);
                        break;
                    case SURVIVAL:
                        p.setGameMode(GameMode.CREATIVE);
                        break;

wouldn't that be much easier?

[undone axle]

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.

[tender shard]

also why are you manually checking whether the player is op instead of just using a properly defined permission in plugin.yml

[worldly ingot]

Permissions are so last year

[tender shard]

your mum

[worldly ingot]

[lost matrix]

https://www.spigotmc.org/threads/handling-custom-items-with-effects.593039/

[tender shard]

this kinda seems overly complicated to me

[worldly ingot]

I like how he just says he's gonna make a resource then just does it

[tender shard]

why not just write "yo, add a string PDC tag to your items to identify it"

[lost matrix]

Ah true... my bad. Let me scrap that.

[worldly ingot]

Easiest resource thread ever

"lmao just get good and do it"

[lost matrix]

XD

[tender shard]

this indeed looks like an overly complicated approach to me

where's the MyCustomItemFactory that implements Factory<MyCustomItem>

[lost matrix]

Really? I tried thinking about the most basic approach i did back when i started using custom items.
What critic do you have?

[tender shard]

that it is overly complicated. I'd simply attach a string to the ItemMeta, e.g. "my-custom-item-id": "explosion-sword"

yeah and that's it

i dont wanna say that using all this enum stuff is bad, but it's definitely overly complicated, especially if it's written for beginners

[lost matrix]

Ah i see what you mean. But this is the basis for the next step in the tutorial where i linked functionality directly to the types

But i can see what you mean...

[tender shard]

as I said, it's definitely useful, but I still think it's way too complicated to be targetet at "beginners" in spigot plugins

for example I didnt know that enums can have abstract methods

[lost matrix]

Maybe i should prepend a short section for actual beginners.

[tender shard]

that'd be nice :3

[tender shard]

intelliJ also really doesnt know about it lol

it only stops complaining when you actually add an enum value (and implement that method inside that) lol

why do you still have 3 same cases?

[eternal oxide]

he means use switch fall through

[tender shard]

these cases are all the exact same

[tender shard]

^

[eternal oxide]

you can make it even shorter using lambdas

but it might become a little harder for most to read

[sterile axle]

that's going to throw a ClassCastException if console runs it

look at the order you do the cast and instanceof

[eternal oxide]

yep, you cast player before testing

[sterile axle]

looks fine without any extra flashy syntax sugar

[wet breach]

Once you learn this you can move onto bitshifting instead

[tender shard]

?

[sterile axle]

on modern java you could make it something like

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String alias, String[] args) {
        if (sender instanceof Player p) {
            if (p.isOp()) {
                p.setGameMode(switch (p.getGameMode()) {
                  case ADVENTURE, CREATIVE, SPECTATOR -> GameMode.SURVIVAL;
                  case SURVIVAL -> GameMode.CREATIVE;
                });
            }
        }
        return true;
    }

[tender shard]

that is so much more ugly

imho

[sterile axle]

🤷‍♂️

just providing alternative syntax

they do the same job either way

[wet breach]

Joking mostly but game mode is just a bit mask

[tender shard]

game mode is a bit mask?

am I too drunk to understand this lol

maybe

[wet breach]

In the packets and nbt data yes

[tender shard]

hm yeah okay lol

[quaint mantle]

Wait, so you can theoretically be in both creative and survival at the same time? lol

[sterile axle]

You could OR the two bit patterns together and send it in a packet but the client would probably freak out about it and not do what you requested

So yes but also no

[quaint mantle]

I said theoretically for a reason lol

[sterile axle]

And I answered

[quaint mantle]

That's pretty funny, but also very weird.

Where would that even be useful?

[sterile axle]

ORing bit patterns in general? or what

[quaint mantle]

Nah, gamemodes being a bitmask

I use bit twiddling all the time

[sterile axle]

oh yeah i dont know

they're exclusive states so not sure why they do it like that

[quaint mantle]

It's certainly an interesting design choice.

[sterile axle]

Minecraft in general is a series of interesting design choices

[quaint mantle]

True

[tender shard]

gamemodes are not bitmasks

they are just 0,1,2,3

[quaint mantle]

Ah, well that answers that

[tender shard]

(taken from this weird wiki.vg site)

[wet breach]

Yeah i was looking at that to see iv they changed and it seems they have

[sterile axle]

im inclined to think he meant they're just bit patterns.

0 => 00, 1 => 01, 2 => 10, 3 => 11; so theoretically you can Creative | Adventure => 01 | 10 => 11 which is spectator game mode

but 🤷‍♂️

(what isn't a bit pattern tho)

[tender shard]

011 isn't 3 but 4 or am I stupid

[sterile axle]

011 is 3

[kind hatch]

If it were a bitmask, any invalid ones could just default to one of the valid gamemodes. Most likely survival.

[quaint mantle]

11 is 3, 1 + 2

[sterile axle]

oh

i fucked that up

kekw

[tender shard]

confirmed, I am stupid

[quaint mantle]

100 is 4

since 4 is a power of 2

[wet breach]

No i remembered them being bit masks for values so 2,4,6,8

[sterile axle]

there i fixed that now

[wet breach]

But doesnt surprise me they changed though

Mojang likes changing everything

All well guess no bitshifting for that then lol

[lost matrix]

6?

[quaint mantle]

6 isn't a power of 2, yeah

[lost matrix]

Ah maybe it was a grey code

[quaint mantle]

It's 1, 2, 4, 8, 16, 32, etc. Each bit represents a power of 2.

[lost matrix]

Yeah but why? Makes no sense because we dont have many flags but just a simple enumerated value

[quaint mantle]

You still talking about gamemode being a bitmask, because I think that was already disproven (or at the very least, recently changed)

[lost matrix]

Im talking about why it would be a bit mask in the first place

[quaint mantle]

Maybe there was plans to mix gamemodes, or gamemodes were setup differently internally. Nobody (but the people who made that system) can say for sure.

[tender shard]

it was probably always just 0, 1, 2

[quaint mantle]

Maybe, I don't know. I haven't really looked into how Minecrafts netcode works, when I write my code, I just accept the fact that (in most cases) it does.

[wet breach]

On a phone lol

But you get the idea anyways

[wet breach]

In terms of packets and storing wise easy to check and compact. But mojangs view on data seems to be the opposite now. Instead of compact going to store more because everything practically being strings lol

[quaint mantle]

Having a bitmask for a field that isn't used as a bitmask would increase the size of stored data. This is because in a bitmask an entire bit is reserved for a single state, if that were the case with say 4 gamemodes, you are already using 4 bits when you could be using 2 (the numbers 0, 1, 2, and 3 can be stored using only 2 bits.)

[tender shard]

well it'd be the same, it's a "byte"

[quaint mantle]

Strings are also useful for networking, since every machine is different strings are probably the safest (if not a little bit expensive) way to send and receive information.

[quaint mantle]

If we are talking about compacting data, that byte can have multiple purposes if not all of its data is used for one purpose.

[kind hatch]

You want to talk about weird design decisions. Why is it that the player gamemode is stored as an unsigned byte while the previous gamemode is signed? You would think they should be the same.

[tender shard]

it could, but mc doesnt do that, never did

[wet breach]

It gets converted to binary anyways for packets. And i was talking about when it was a bitmask not talking about what it is now

[sterile axle]

because it says it could be undefined, for example when they just join

[tender shard]

i also wondered about that when I looked through ViaVersion lol

[sterile axle]

it says it right in the description

[kind hatch]

I fail to see how that would be the case considering that there is a default gamemode option defined in the server properties.

[sterile axle]

or if they haven't changed gamemodes before

[tender shard]

i wonder why the previous gamemode would matter in the first place

like, why

[sterile axle]

it looks like a potentially optional field, only used in the debug panel

so if you dont want to share it, just send -1

which is fine

[tender shard]

why does it not keep track of yesterday's time, or last week's health, why only previous gamemode

[sterile axle]

cause that's not shown in the debug panel?

[tender shard]

yeah but that exactly is my question

why the heck does the debug panel show my PREVIOUS gamemode

[sterile axle]

refer to this

[tender shard]

that is true

[kind hatch]

Wait, has the debug menu started showing that information?

[tender shard]

I still wonder who thought "ah yes, lets show the PREVIOUS gamemode, that might be useful to some people... yesterday"

who decided that haha

[quaint mantle]

I think minecraft stores previous gamemodes because there is a shortcut key to swap gamemodes back and forth

[tender shard]

there is?!

[kind hatch]

There is and that's what it's used for

[tender shard]

there is a key to swap gamemodes? o0

[wet breach]

How else would it know to set your game mode to when you come back?

[kind hatch]

Hold F3 + Tap F4

[sterile axle]

so it would be -1 when the gamemode has never been changed, which is why it's a signed byte

[tender shard]

in that case, the "old" and "new" gamemode would be the same

[wet breach]

Not necessarily

[sterile axle]

make a plugin that collects random animals if you're holding a certain item, then makes them follow you around when you type a certain command i guess 🤷‍♂️ good practice if nothing else

[wet breach]

But anyways we probably shouldnt infer too much when it comes to mojang code because as what simple said they dont always make sense in the why

[kind hatch]

@tender shard This is what the switcher looks like.

[tender shard]

does it need to be useful?

[quaint mantle]

Isn't there another key to switch directly to the previous gamemode though?

I thought there was

[tender shard]

is that java edition? o0

[kind hatch]

Yes, it's in Java

[tender shard]

never saw that

[kind hatch]

It's been in the game for a couple updates now.

[kind hatch]

AFAIK, there is not one. You'll just have to cycle through all of the gamemodes. Fortunately there is only 4 of them. 😛

[quaint mantle]

Ah, so then that doesn't actually answer why the previous gamemode would need to be stored.

[kind hatch]

It's for quick switching. I love it.

It's so useful for creative to spectator.

[tender shard]

make a plugin that when you send a message like "this is a sentence", it shows it as separate messages per word, like
mfnalex: this
mfnalex: is
mfnalex: a
mfnalex: sentence

[rotund ravine]

Dumb

[kind hatch]

Just tap the keybind once to switch quickly

The weird thing is that I think it's per server.

[quaint mantle]

So the list re-orders itself based on what the previous gamemode was?

[tender shard]

no the list is always the same

[kind hatch]

No, it just moves the selection cursor to the previous gamemode you had before it will continue to cycle.

[tender shard]

but it selects your previous gamemode

^

like shadow said

[quaint mantle]

Ah, I see

Ok that makes sense then.

[rotund ravine]

F3 + N: Cycle between Spectator mode and the previous gamemode. Switches to Creative mode if there is no previous gamemode. Requires cheats to be enabled.

[wet breach]

Cheats for single player

[tender shard]

having cheats enabled in single player is sooo stupid

like "oh I need some dirt. well I COULD go back to my base and get it, I'Ll just /give it to myself right now, then remove it from the chest later" said nobody ever

and then one keeps cheating the whole time lol

[lost matrix]

It has been a long time since ive actually played this game...

[tender shard]

same

I play it usually for a week when a new version comes out

[lost matrix]

Same. Kind of. I have a german stream who has an event every time a new version comes out and im
providing the server/plugins for that. I play in the opening days when we have 50-100 players and then
i get bored

But modded i can stay interested in a bit longer

[quaint mantle]

what is the farthest distance an arrow shot from a bow or crossbow could travel??

[lost matrix]

At least 5

[quaint mantle]

at most?

[lost matrix]

A bit more

[quaint mantle]

i require an exact measure of the upper bound.

for something i am working on.

[lost matrix]

We need more constraints. Max distance is achieved by a 45° angle.
But if the arrow lands below the height it was shot from then it will fly further.
Are we speaking about a perfectly flat area?

[quaint mantle]

yep.

the highest distance it can travel, shot from build height to bedrock.

[lost matrix]

In most cases this will fly outside of loaded chunks

[quaint mantle]

hm

[paper venture]

If I check every mob in the world for meta data every tick, will it affect the performance?

[lost matrix]

Yes

[quaint mantle]

but that depends on how many chunks you set as simulation distance in the world folder.

[round finch]

Interesting math

[quaint mantle]

and there could be other players around.

[lost matrix]

Sure

[quaint mantle]

that could be loading chunks in that direction.

[paper venture]

Significantly?

[quaint mantle]

yeah.

depends on the number of mobs.

[round finch]

Just run the test and shoot an arrow

[lost matrix]

Depends on how the data is stored and how efficient your algorithm is

[quaint mantle]

to be more precise.

[onyx fjord]

Depends how much you do

Or how heavy it is

[paper venture]

just checks for a value in persistent data container

[quaint mantle]

you can run it an async thread.

[lost matrix]

What are you trying to do?

[onyx fjord]

And just stores it that's it?

[quaint mantle]

to make sure it does not affect performance on the main game thread.

[paper venture]

yes

[onyx fjord]

Idk if you could add caching to it

PDC can be a bit expensive at times.

[paper venture]

using BukkitRunnable?

[quaint mantle]

using Bukkit.getScheduler().runTaskAsynchronously();.

BukkitRunnable is just a lambda.

you gotta pass that lambda into the function.

[onyx fjord]

What pdc item are you storing? Maybe it doesn't need to be like that

[quaint mantle]

for it to run.

[lost matrix]

Usually you would separate the lifecycles of your data:
Entity loads -> load from PDC into data structure (Map<UUID, SomeEntityData>)
Entity unloads -> save from data structure back into PDC

[kind hatch]

Here's something that'll throw a wrench in your problem. Projectile speed is based on how fast the entity is moving, so if a player has speed while shooting a bow, then the arrow will go farther.

[quaint mantle]

this is annoying

lets just assume player is stationary.

anyway, i have this database where i store permissions for the player per chunk.

and i am loading and caching chunks around the player.

i am not sure how much to cache though.

so a player fires an arrow in some random unloaded chunk, there has to be a database query running on the main game thread to check if that row exists.

[lost matrix]

What are you trying to achieve?

[quaint mantle]

because events cannot be cancelled asynchronously, probably.

[paper venture]

I want to each attack add a stack of slowness, up to 3 stacks, but I thought that in my plugin there would be a lot of slowness reasons so to separate them I make attacks add attribute modifier and add a INTEGER tag to PDC, this tag decreases every tick and if it is 0, then I remove attribute modifier

[quaint mantle]

just a plugin with chunk permissions.

[lost matrix]

More detail pls. You want a permission to prevent an arrow to fly into a chunk which the shooter has no permission for?

[quaint mantle]

something like that, yep.

[lost matrix]

I would just check for projectile hits and cancel those. Tracking projectiles is a hustle.
But what do you need the max distance for then??

[kind hatch]

Jeez. I hope you're using blacklist permissions instead of whitelist permissions.

[quaint mantle]

i have a table in the database where i am storing chunks that a player has been trusted to, the data is loaded and cached around a certain distance of the player.

thought that would be more efficient than loading permissions for every loaded chunk for every player online on the server.

that would take up M*N time and space.

eh

too much off a hassle.

i was just thinking about this in terms of edge-case anyway, probably won't be too bad.

[paper venture]

I think I can use a manager here like the manager you showed me yesterday, but is it a good idea to create a new manager every time I need to work with the data this way?

[lost matrix]

This means your data is now player scoped and not chunk scoped. That sounds like a very questionable idea
if you want to protect the chunks and not the players.

[lost matrix]

Create managers for every major program section you want. But only ever create one instance of your manager. (1 !)

[paper venture]

Thanks!

[kind hatch]

No, the purpose of a manager is for itself to "manage" the instances it'll create. There is hardly a need to create multiple instances of a manager class.

[tender shard]

one

/shrug if you ever only will need one instance, might as well make everything static

[lost matrix]

Just to make sure bc i dont wanna read "why does my map in x not contain the stuff i put in y" again

[quaint mantle]

how would you implement it?

https://imgur.com/XAzyfze

[paper venture]

I mean if I need different managers, for example I have a manager to work with individual glow effect, now I need a new manager to work with slowness...

[quaint mantle]

there can be more than one player trusted to a chunk

[kind hatch]

Yes, but you wouldn't need two instances of that type of manager.

[lost matrix]

Wait do you have several types of permissions or do you just have a binary value trusted/untrusted

[quaint mantle]

its a bit complicated so, if a player is trusted, it has all the permissions.

[paper venture]

Yes, these managers will be completely different types. Maybe I should consider making a manager generator if it is possible...

[quaint mantle]

but there are global permissions

for untrusted players.

[tender shard]

make it a ManagerFactoryFactory implements Factory<ManagerFactory> and call it a day /scnr

[kind hatch]

I don't get it. What conditions need to be met in order for the projectile to be removed?
Like, if Player1 and Player2 are trusted to chunk1, chunk2, and chunk3, that means that if the projectile landed in chunk4 that it would be removed for both of them?

[tender shard]

"enterprise" java code is usually a big joke

[quaint mantle]

if a player is trusted to that chunk or the global pvp permission for that chunk is enabled, or the chunk is unclaimed, the damage from the projectile is not cancelled.

its a bit complicated to explain in words, i will just show some pictures.

[tender shard]

i worked for a software company in my town (INDAL GmbH) and they used FactoryFactories and stuff, and that's just weird

they also used fuzzy logic for EVERYTHING

[kind hatch]

Oh man. So each chunk has an additional flag that needs to be checked? Are you storing that data or is another plugin handling that?

[quaint mantle]

i am currently storing the data, yep.

in a database.

[lost matrix]

Its basically:
unclaimed -> fallback
== claimed
== trusted -> allow
== untrusted -> deny

fallback -> global default

[quaint mantle]

claimed (global pvp enabled) -> allow.

is how that is set up.

i mean

its a pretty standard chunk claims plugin.

https://imgur.com/qUfQ2BQ

global permissions.

anyway

[kind hatch]

That looks like permissions for the claim, not global pvp perms.

[quaint mantle]

i think the server just has to deal with the sql query lag.

yeah, permissions for the claim, globally.

for all players.

that are not trusted to that claim.

[lost matrix]

Anyways lets go through both approaches.
Lets assume that you give each player a LongSet and simply load all trusted chunks when they join.
On average a player may have 100 chunks assigned to them (which is a lot 1600 x 1600 size)
which means we have to allocate 100 * 64 bit which comes down to 6400 bit = 6.4kBit
A very good server can hold a max of 100 concurrent players which means you need to
Allocate 100 * 6.4kBit = 640kBit which is around 0.6MBit. Add maybe 2MBit for all the
data structure headers and a bit extra which comes down to maybe 3MBit or half a MByte.
So do you think you can spare a few megabytes?

[quaint mantle]

i can do that

[tender shard]

I'd just use the chunk's pdc to store "who's the owner of this chunk"

[kind hatch]

Do you have claim groups? Like owner, member, nonmember?

[quaint mantle]

and that is why i came here to ask

i am not sure about idea of M*N time and space complexity.

[lost matrix]

This is the agreed standard when it comes to chunk permissions.
Make the data chunk scoped and not player scoped.

[quaint mantle]

loading trusted data for every player.

and no, i dont how many claims players may have

may be 100 or maybe 1000, idk lol, i am not using this plugin.

so i dont wanna load too much stuff.

[tender shard]

a max of 100 players? o0

[lost matrix]

Ok but you need to average that out.
How many trusted players will the average chunk have?

[lost matrix]

Maybe a bit less in 1.19

[tender shard]

wtf

[kind hatch]

Please, I implore you to setup a server and see it crawl to its knees once 50+ try and join.

[tender shard]

I had a tiny Ryzen 5 3600 a year ago, using 1.19.X (whichever version was recent about a year ago) and I got about 30 concurrent players withOUT a pregenerated world, they were flying around with elytras and stuff, with solid 20 TPS. So I doubt that "100" is the limit

[quaint mantle]

what was the render and simulation distance?

[tender shard]

12

or 16? definitely NOT below the default limit

I don't remember it but I definitely raised it, or not changed it at all

[quaint mantle]

i currently have an smp and it definitely struggles with more than 11 players.

in terms of TPS.

[lost matrix]

We used a Ryzen 3600 for our last event and i even pregenerated the whole map. I optimized the jvm params
and limited a lot of the common cpu hogs like entity limit and hopper actions etc. Everything above 65 got us a tick average of 40ms which is a soft limit

[tender shard]

are you using a dedicated server?

[quaint mantle]

although it runs fabric with lithium, starlight, ferritecore, and all those sorts of mods.

its a vanilla smp.

[tender shard]

well it probably also depends on which plugins people use. I basically only had 4 or 5 plugins running

[lost matrix]

Only one plugin i wrote myself which was optimized for this. (Didnt even show up in the 1% timings )

[quaint mantle]

instead of chunk scoping it, why not just load chunks in a certain distance of the player?

this way i dont have to load 1000 chunks, in case the player may have that many claims.

[tender shard]

anyway, it's definitely possible to have more than 100 players on one server, I've worked for ElderCraft when they still had about 300~ consec players daily, and they also ran everything off one dedicated machine (however that was 1.16/1.17 times)

[quaint mantle]

which is why i asking the maximum distance an arrow can travel.

[lost matrix]

Sounds error prone to me. Either load all data with the player or load all chunk related data with the chunk.

[quaint mantle]

why would it be error prone?

[kind hatch]

At minimum 50 blocks because of the achievement. Probably around 4 chunks if you get the right angle.
Then it could go farther if your velocity was somehow increased.

[lost matrix]

Imagine you have an ender pearl stasis chamber and tp yourself fast enough and inflict some damage before your radial data is loaded

[buoyant viper]

if u cheat, it could possibly be infinite

[quaint mantle]

yeah i know what you mean, i have optimised for that edge-case

[lost matrix]

And thats just the first thing i came up with. Players can be vile

[quaint mantle]

when i said i am loading chunks around a player, i am not loading them around the player exclusively

player may have a chunk loader then running a tnt duper

or something like that

which is why i cache them as well.

or something idk, i will get back to working on it

enough procrastination.

[kind hatch]

Realistically, the farthest a projectile can go is pretty much within the vanilla render distance. You can get around 250 blocks of distance with riptide and speed. However, anything past that is due to variables outside of the vanilla gameplay.

[lost matrix]

Modern servers have a lot of ram. If you can trade some ram for less cpu usage or more robustness then go for it.

[quaint mantle]

the cpu usage is not affected

actually, it is affected if i am loading M*N chunks where M is the number of players online and N is the number of chunks loaded throughout the server.

[lost matrix]

Speaking of loading things out of a database on the main thread when a chunk loads: Where is Redempt? Didnt see him recently.

[tender shard]

https://github.com/JEFF-Media-GbR/BetterTridents/issues/5 has anyone ever encountered this issue? (snakeyaml complaining about the awareness thing in plugin.yml) o0

[kind hatch]

awareness?

[quaint mantle]

it is loaded only if it is not already in the cache.

[tender shard]

yes

the awareness tag in plugin.yml

[kind hatch]

tf? What does it do?

[buoyant viper]

isnt it a very not necessary and/or deprecated tag

[kind hatch]

I've never even heard of that tag before so that's why I'm confused.

[tender shard]

yeah it is

but it still shouldnt cause problems

[buoyant viper]

ive seen it a total of one time, mentioned here, in this discord

@kind hatch

:v

[tender shard]

when I made that plugin, this tag was still mentioned in the official spigotmc wiki article about plugin.yml

meanwhile, it's not there anymore

but it should still not fail to load, after all yamllint.com tells me it's valid yaml

[kind hatch]

How long ago? Cause I have never seen it and I've been keeping tabs on stuff since 1.6

Oh wait

[tender shard]

2021, last update 2022

[kind hatch]

Was it that weird flag that was used internally?

Like PluginAwareness.Flags or some shit?

[tender shard]

yes

probably paper removed it again, calling this "api improvements" lol

[rotund ravine]

Makes sense

[kind hatch]

Well it's deprecated in spigot too.
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/plugin/PluginAwareness.Flags.html

[tender shard]

yeah it is deprecated

but it's not removed

the whole flag was totally useless anyway, iirc. still it's weird to just remove it

[kind hatch]

Well if it is functionally useless then I don't see why you should keep it around, but that's just me.

[tender shard]

I am also going to remove it, I just wonder why it fails to load in paper

[kind hatch]

Does paper ever update the snakeyaml dependency?

[tender shard]

i don't know what they do

[kind hatch]

Could be an outdated one trying to read a new format.

Or a new one that dropped that syntax

[tender shard]

well it definitely worked in paper when I released that plugin, after all I use paper myself sometimes

if they wouldn't have banned me from their discord, I could ask there, lol

[kind hatch]

Apparently it shows as null.
Guess its not that surprising since the value starts with an exclamation mark.

[tender shard]

it is still valid yaml, isn't it

[buoyant viper]

https://docs.ansible.com/ansible/latest/reference_appendices/YAMLSyntax.html doesnt look like it

[kind hatch]

So, either put it in quotes, or don't use it at all.

[tender shard]

a list is not a scalar

well, the identifier of the list is, but not the contents of that list, iirc

also I just checked it using paper 1.19.3 and it loads fine for me, very weird. no idea where the dude in the github issue got this exception from

it loads just fine for me lol

[kind hatch]

Yeaa, I thought it might have been used for data serialization.

Guess it just comes down to the interpreter.

[tender shard]

yeah I'll just remove it. I'm still confused about why it errors for them on paper 1.19.3 but not for me on latest paper lol

[quaint mantle]

nvm.

[kind hatch]

@tender shard It looks like spigot updates the snakeyaml dependency every so often. Version 1.30 was used for 1.18-1.19.2. Version 1.33 is being used for 1.19.3 and onwards for now. Paper probably followed suit. So maybe there was a change somewhere in those versions that had caused that error.

[tender shard]

yeah but in that case, it must have been an "in-between" thing because it works fine for me using paper build 420 o0

which is the latest

very weird

why does IntelliJ not support tabs on windows D:

this is so annoying

on mac it's just always one window

[buoyant viper]

YAML docs really are something, trying to look for stuff regarding ! brings me to "tags", idk wtf they r at all, but they show a syntax similar to urs as invalid

https://yaml.org/spec/1.2.2/#rule-c-ns-shorthand-tag

tags are also mentioned in snakeyamls error that user reported

[tender shard]

have you heard about their "placeholder" stuff?

[buoyant viper]

ive never used yaml in depth

i usually opt for json

[tender shard]

yaml allows stuff like this: https://github.com/JEFF-Media-GbR/ChestSort/blob/master/src/main/resources/gui.yml

[buoyant viper]

oh aliases

i did read that in the spec sheet

[tender shard]

erm yeah

quite nice, I wish XML would support this

[buoyant viper]

oh woops not alias, anchor https://yaml.org/spec/1.2.2/#rule-c-ns-anchor-property

[tender shard]

oh yeah

I think I wrote a blog post about this shit but never published it

[buoyant viper]

oh its anchors & and aliases *

[tender shard]

yeah the anchor is the definition, and the alias is the "reference to it"

whatever

[buoyant viper]

ye

[tender shard]

might as well have written "portugal" lol

"stop travelling through portugal, mr. trident, you can get to morocco instantly by plane"

[buoyant viper]

instructions unclear, trident was stolen in Detroit

[tender shard]

unfortunately, it gets stolen into the nether

[quaint mantle]

Stupid netherlands, always stealing my trident deliveries.

[tender shard]

yeah

fuck netherlands

their weed is also much too expensive

but they definitely do know how to properly fry fish (kibbeling)

I'd sell my left leg for some nice kibbeling right now

[paper venture]

Is there a way to get a list of only loaded entities? Or world.getEntities() already does so...

[tender shard]

that's already returning only loaded entities

I'd sell my right leg to be able to get a list of not loaded entities

[paper venture]

Haha thanks!

[tender shard]

np

[quaint mantle]

Imagine what magic would be required to get a list of something that technically doesn't exist until it's loaded.

[tender shard]

it's called MojangsonParser or similar lol

I use it to get the PDC of offline players for example

[quaint mantle]

It looks like a json serializer/deserializer but for NBT

[tender shard]

exactly

[quaint mantle]

There is still the issue of knowing which region files have unloaded entities without looping over all of them.

[tender shard]

usually all of them I guess

[quaint mantle]

That's a lotta entities

[tender shard]

yeah lol

[quaint mantle]

Are entities really that common? I guess bats, but I don't like the idea of every chunk in a world having at least 1 entity when it's seemingly empty.

Plus, don't entities that aren't persistent get effectively deleted once the chunk unloads?

[tender shard]

iirc, hostile or ambient mobs aren't even saved unless they have a custom name or anything

[paper venture]

Nice this code takes only 0.005 seconds to run so I can do some unoptimized stuff!

[tender shard]

if you run it twice, it probably takes less time

[quaint mantle]

Keep in mind, everything all together (both Minecraft and all plugins) only have 0.05 seconds to finish its processing before your TPS starts dipping below 20.

[paper venture]

Yes, thats clear, I will try not to overload my TickTask for too much

[hybrid spoke]

just overdrive the ticks so you have more ms to fuck around

[quaint mantle]

Wouldn't increasing the TPS reduce the available processing time per-tick?

[eternal oxide]

Yes he was joking

[hybrid spoke]

but he got a point tho 🤔

just underdrive the ticks so you have more ms to fuck around

[eternal oxide]

Use reflection to inject more ticks so you can take as much time as you like.

[tender shard]

just make /tps return a String "20 20 20" and call it a day

[eternal oxide]

fixed

[hybrid spoke]

make your ticks negative so you have infinite ms

[tender shard]

isn't there actually a spigot plugin for this?

[eternal oxide]

lol probably

I want my own private tick

[tender shard]

i remotely recall that there's a spigot plugin that allows you to change the tickrate, but it doesnt work on paper

[hybrid spoke]

yes there is

literally called "overdrive"

https://www.spigotmc.org/resources/overdrive.73779/

[tender shard]

oh yeah that one

[chrome beacon]

or you can use https://modrinth.com/plugin/limitless-tps

[tender shard]

modrinth? for spigot plugins?

[chrome beacon]

That's a Paper plugin

[tender shard]

haha

[hybrid spoke]

i like the FAQ

[tender shard]

I like how paper shot it's own leg by inventing this stupid "paper-plugin.yml" thing

[chrome beacon]

hm how so?

[tender shard]

because it makes plugins not be compatible with spigot anymore?

if someone only uses the paper-plugin.yml thing

[chrome beacon]

You can have both a paper yml and a spigot yml

[tender shard]

you can, but people won't

[mighty pier]

😱

[tender shard]

they will read exactly one tutorial, and only parts of it, then they'll continue to just provide this paper file, and then they'll be confused about "why it's no workings on spigot uuuuh"

[chrome beacon]

If people want to make spigot plugins they'll just continue to do it like normal

[tender shard]

in a perfect world, this would happen

in a perfect world though, paper could just have used the same .yml file to add their additions

or, even better: just contribute upstream

[chrome beacon]

If people misunderstand that the paper-pluign.yml is only for paper then that's not papers fault

[tender shard]

they want you to include 2 yml files?

[chrome beacon]

You're free to choose

You don't need the Paper one

[tender shard]

and I said that people will not understand this because nobody ever reads a tutorial completely, and that's why it'll cause problems

[remote swallow]

Loads of spigot plugins broke on paper bc of their paper-plugin

[tender shard]

it's usual for paper to break stuff, e.g. them fixing tnt duping by default is already kinda stupid imho

it should be an OPTION to fix this, not a DEFAULT

oh also the API incompabilities, e.g. remember when AdvencementInfo broke after spigot added that? And then plugins using the existing paper api ofc all broke down because Paper decided they must return a component instead of a string. If they would just contribute upstream, there'd be literally no problems lol

i never understood why everyone's so afraid to sign a tiny cla that only consists of like 2 pages

I also further have to add that paper adds many useful things, like way faster chunk loading and stuff

but the whole idea of "moving away from spigot" is a bit stupid imho

[eternal oxide]

Most don;t like having to provide personal info

[hybrid spoke]

we gotta make spigot more performant so people stay with it

[tender shard]

why not? why is everyone so afraid of that

[eternal oxide]

personal info handed out to who knows who is nto very safe

[tender shard]

my address is Junkerstraße 17 in 48165 Münster, Germany. My phone number is 015174202224. I could continue and tell you my iban. what is anyone going to do with such info?

[remote swallow]

Md is very sadlfe

Safe

[tender shard]

and as already explained, you only give that info to md_5, not to EVERYONE

[eternal oxide]

impersonate you and open credit in yoru name with enough info

[remote swallow]

^^

[hybrid spoke]

registering with your phone number on some scam site now

[quaint mantle]

Both ConfigurationSection.contains(section, true) and ConfigurationSection.isConfigurationSection(section) appears to be returning true for a field that doesn't exist... Does anybody have an idea as to why this might be happening?
The section exists in the default config.yml but not in the data folder one.

[tender shard]

how is anyone supposed to impersonate me just by having my name, address and phone number? o0

[hybrid spoke]

• sending you elefant shit to your home

[eternal oxide]

thast the point, You don;t actuall yknow who has access to that information. Everyone assumes it's only md5

[tender shard]

anyone can do that already

[hybrid spoke]

ever happened?

[tender shard]

they can just open "google earth" and scroll to a random place, then check the address

[tender shard]

no but I'd love it

[hybrid spoke]

so i will be the first

[eternal oxide]

with that info they can use social engineering to get all yrou details from yoru carrier

[tender shard]

what do you mean with "all your details"?

there are literally NO details that I am hiding besides my reddit username and my banking pin

[eternal oxide]

any that yoru carrier has. They can also get your phone spoofed

[tender shard]

wdym with "spoofed"?

[eternal oxide]

It happens often

[remote swallow]

Why hide reddit username

[tender shard]

because I only post nudes there

and I dont want spigotmc people to see them

[remote swallow]

Impersonate ur number from elsewhere

[eternal oxide]

they clone yoru phone and basically get all texts you send/receive

[hybrid spoke]

spoofing your phone number to get your reddit username

[tender shard]

I dont know how calling works but I am pretty sure that the number you call can see the actual phone number

[eternal oxide]

its very common way of hacking 2fa

[tender shard]

idk my ubikeys are safe and sound in a drawer and have never been hacked

[eternal oxide]

yet

[remote swallow]

We have your address

[eternal oxide]

Thats the thing about personal info, once enough of it gets out there the more you become vulnerable

[remote swallow]

We just break in and take them

[tender shard]

if someone is so stupid and enters his username and password on a website called "wafkwuagfawfawfgawufawfawfawfa.random-chinese-server.com", it's their own fault. doesnt have anything to do with "I am afraid to sign the CLA because the code I provided is actually stolen"

[eternal oxide]

and breakign in becomes quite easy, often with just a fishing rod

[tender shard]

if anyone would actually be afraid of their "personal data", they wouldn't use discord

which is erm, quite known to ignore the GDPR and sell data to everywhere

[wet breach]

This is why i lock my credit

[eternal oxide]

I gave no personal info to discord

[quaint mantle]

Can I bump this?

lol

[eternal oxide]

however I did sign the cla

[tender shard]

nobody can tell me that "randomPaperContrib" doesnt want to sign spigot's CLA because "I'm afraid of giving away personal info" but then continues to talk on their discord server haha

[hybrid spoke]

well. im not a fan of publishing my private info but a CLA of a verified longyear-standing project is something else

[tender shard]

also, md doesnt even check which data you put into the CLA. you could just enter some random address

[eternal oxide]

you could but it's also on Google servers

[tender shard]

what is on google's servers?

[eternal oxide]

as it uses Google to authenticate

[tender shard]

?cla

[undone axle]

https://www.spigotmc.org/wiki/cla/

[eternal oxide]

when you signed the cla it was via google

[wet breach]

As if google didnt already have personal info

[tender shard]

yeah that is true

but everyone's data is already on google anyway

I really never understood the idea of everyone now saying "lol I don't want my data being on google"

[eternal oxide]

perhaps perhaps not, it's still a reason people are reluctant to sign it

I had to think twice before I signed

[wet breach]

I didnt think twice

[buoyant viper]

i kept the tab for a lil while before i finally signed off on it

[eternal oxide]

You young'uns throwing caution to the wind

[wet breach]

Google knows where i live and i am forever in the library of congress

[buoyant viper]

kinda forget now if i signed off with my legal name or my to be legal name

[tender shard]

yeah and it's a reason that I do not understand, and also it adds a huge downside to paper:

it might be taken down anytime. someone could just message github and claim "yo that's my code": then they proceed to send a tiny fracture of code that's actually similar. Then github asks the owner of paper's repo "yo, is it true that you stole it?" then they reply:

...

what do you think? spigot could reply
"The dude who pull requested this code promised to me that he wrote it himself, here's the signed PDF:"

paper would have to say:
"erm idk"

[wet breach]

Unless the library of congress burns down again

[tender shard]

this was a reply to @eternal oxide btw, but I forgot to tag is as reply

How to play an animation for a player with plugin (animation aldready in client's resource pack)

[tender shard]

wdym with "animation"

[quaint mantle]

like custom animation for player, can spigot plugin send packet that play an animation in client side?

[tender shard]

I still don't know what you mean with "animation"

[quaint mantle]

like run, walk, swing arm etc... you know, player's character's animation

[tender shard]

ah ok

for "swing arm", there's api for that, yes

run, walk, i am not sure, but I dont think you can do this using spigot API, you'd probably have to use NMS

[quaint mantle]

anyway, what is the way with "swing arm"

[tender shard]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/LivingEntity.html#swingMainHand()

swingOffHand() also exists, ofc

[pseudo mica]

Hi, I have a public chat on redis and a guild chat(private) on bungee, someone knows how to block the chat packet when someone write in the bungee chat because right now when you write in the bungee chat the message appears also in the public one 😦 ?

[tender shard]

whut

a "public chat on redis"?

[pseudo mica]

Yes to send the message on every server, its the same of bungee but on redis

[tender shard]

yeah I am just confused of you calling it "public"

does everyone know your redis password, or what o0

[pseudo mica]

No, why? 🙂

[tender shard]

I asked "why" because you said "public"

[pseudo mica]

I mean the normal chat of minecraft, its public

[tender shard]

oooh

lol ok

[hybrid spoke]

so you want to do some sort of cloud system where you sync messages across servers via redis or what

I just want to avoid sending the message in both chat when I write in the bungee one

[tender shard]

well, how the chat is interpreted depends on the plugins you already use. by default, the proxy only forwards the chat packets to the server where the player (receiver, AND sender) actually is on

if you see the same message twice, you installed some plugins which caused this problem

by default, chats are always "per-server"

[hybrid spoke]

bungee has a chat?

[tender shard]

no

[hybrid spoke]

was about to say

[tender shard]

it just forwards the existing packets

if they see messages twice, they already use some plugin

if you'd remove all plugins, I'm sure this wouldn't happen

[pseudo mica]

Yes, the redis one is the chat. When I turn one the guild chat, which send message over bungee to other servers, I see the message in redis and in guild chat

Is not possible to block the packet after sending over bungee?

[tender shard]

I really don't understand what you're talking about

if you could explain it again in a bit easier words, maybe I could understand it

[tender shard]

you can intercept any packet sent using a custom netty handler (or if you hate yourself, using ProtocolLib)

I would however never recommend ProtocolLib, it's a pain

[pseudo mica]

So, I write in chat and the message is sent over redis to every other server. When I turn on the guild chat it sends the message over bungee but also in the redis

[chrome beacon]

ProtocolLib isn't that bad

You just need to learn how it works and then it's fine

[tender shard]

it's the worst library I have ever seen in my entire life, and I have seen stuff like XStream

[tender shard]

haha how it works

it promises to be cross-version but actually all it does is like "getIntegers()" and then you still gotta care about "which integer" is "which"

imagine this:

public class MyExamplePacket extends Packet```

[chrome beacon]

Yeah it doesn't do much more than a custom netty handler

[tender shard]

and now it adds a new integer parameter into the constructor

how is protocollib gonna handle that? oh right, it doesn't. you are supposed to do this on your own

and that's why I think that protocollib is nothing but a joke

I might be wrong of course, and maybe I simply misunderstood something

[tender shard]

yeah that's what I figured. It still doesn't do any X-version compatibility

all it does is to abstract the classes even further. so instead of doing

new PacketExample(1,2,3);

people now do this:

PacketExample ex = new PacketExample();
ex.getIntegers().set(0,1);
ex.getIntegers().set(1,2);
ex.getIntegers().set(2,3);

seems a bit useless to me, but ok

maybe it once was useful, idk

why would anyone want to do this instead of just calling the proper constructor of that packet

[wet breach]

Because they dont want to mess with nms and reflection

[tender shard]

but they do

they literally say "set the first "int" field in the constructor to 1"

cant get any worse than that imho

this PacketWrapper thing on github was a proper approach but yeah

it died

[wet breach]

I am saying for people who use protocollib

[tender shard]

that's also what I'm talking about

[wet breach]

Well you dont need nms or reflection if you are using protocollib otherwise pretty useless to use the lib

[quaint mantle]

where can i view all code of that method, the website show only the name of method

[wet breach]

?stash

[undone axle]

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

[quaint mantle]

i can only see the interface, where should i can find how that method actually work?https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/entity/LivingEntity.java#516

[tender shard]

but you still need to code version dependant code

[orchid gazelle]

I use BuildTools -> target > decompiled for viewing sourcecode

[tender shard]

protocollib is sooo useless in my eyes

[orchid gazelle]

Never used it, but I don't think I want to

[tender shard]

clone craftbukkit

then check that

[tender shard]

nobody wants to use it, it's trash

[orchid gazelle]

A Jägermeister a day keeps the doctor away

[tender shard]

I'll need some bencodiacepines to survive this day anyway

[orchid gazelle]

Oh yes same

[tender shard]

rivotril high five

[orchid gazelle]

I got holidays this week and got sick on monday yikes

[tender shard]

or valium or tavor or whatever

[quaint mantle]

bukkit or craftbukkit, what different

[buoyant viper]

craftbukkit is the implementation of bukkit api for minecraft

[tender shard]

https://blog.jeff-media.com/bukkit-vs-spigot-api-vs-craftbukkit-vs-spigot/

[orchid gazelle]

Isn't it basicly just nms stuff but in an external library?

[tender shard]

it's even worse

I explained it above

[buoyant viper]

well if ur messing with packets, ur already messing with version specific code :V

[tender shard]

exactly

[buoyant viper]

unless its a reeaallllyyy generic packet like chat, payload, or maybe player movement

something less likely to change or be removed

[orchid gazelle]

You really need some Jäger to not die while porting Version-Dependent stuff

[tender shard]

I doubt that, the NMS classes change all the time. and if they really "wouldn't change", then one could easily just provide a wrapper for each class

[tender shard]

yes, I'm addicted, not the right place to talk about it though

[buoyant viper]

god yeah

[tender shard]

just google "alcohol withdrawahl symptoms" if you care

[orchid gazelle]

Ok

[buoyant viper]

i remember trying to port some old ass simple forge mod to a modern version

[orchid gazelle]

Ouch

[buoyant viper]

and between mapping changes and literal code changes (ie. Gui handling), it was aids

[orchid gazelle]

Forge porting is 10x worse than plugin porting

And plugin porting is already insanely painful

[buoyant viper]

it was like 1.7 mod ported to 1.13 or 1.14

[orchid gazelle]

Even worse

Its literally a completely different modloader lol

[tender shard]

usually one can just use the mojang maps and 99% is fine

[orchid gazelle]

Im using mojang mappings nowadays

Imma hope porting gets easier with that from now on

[quaint mantle]

what best app to decompile plugin jar file to view source code

[tender shard]

btw, updated blog post: https://blog.jeff-media.com/how-to-make-maven-automatically-put-your-plugins-jar-into-your-test-servers-plugins-folder/

[orchid gazelle]

lmao

Alex with the blog post for everything

[tender shard]

I am just tired of answering the same questions every day, again and again

like for example "lol how do I make custom heads"

or "uuugh how do I tell maven to output my .jar to C:\MyServer\plugins"

[orchid gazelle]

Keep it up bro

Ah yes Alex btw. I found the issue why the multiblocks lag

[tender shard]

what is multiblocks?

[orchid gazelle]

The schematic thingy you know

[tender shard]

I knew it? I don't recall that

[quaint mantle]

what should i do, i just clone craftbukkit and open with intellji Could not find artifact org.spigotmc:minecraft-server:jar:1.19.3-R0.1-SNAPSHOT in minecraft-libraries (https://libraries.minecraft.net/)

[orchid gazelle]

Nono I mean I know how to fix it

[tender shard]

you have to run buildtools

?bt

[undone axle]

https://www.spigotmc.org/wiki/buildtools/

[orchid gazelle]

Thing is that the stupid client inits, wipes, inits, wipes the light-chunks everytime

So what I gotta do is init them one time and keep them there by faking like a barrier block so it does not keep wiping it

[lost matrix]

is "minecraft-server" actually an artifact?

I guess it is

[quaint mantle]

what actually is "artifact", i see it but i dont understand it

[buoyant viper]

artifact would be like the jar

[lost matrix]

An artifact is just a piece of software. In the maven context its mostly a compiled jar.

[cold field]

Does anyone have a github-action that when there is a release it publish the artifact even on spigot?

[tardy delta]

me wondering how people understand how to work with github 😢

[stiff snow]

Sry but can anyone help me?
I created a list with following command List<PotionEffectType> effects = Arrays.asList(PotionEffectType.values()); and now i try to remove some effects
with following commands ```java
List<PotionEffectType> removeeffects = new ArrayList<>();
removeeffects.add(PotionEffectType.REGENERATION);
removeeffects.add(PotionEffectType.FIRE_RESISTANCE);
removeeffects.add(PotionEffectType.DAMAGE_RESISTANCE);
removeeffects.add(PotionEffectType.INVISIBILITY);
removeeffects.add(PotionEffectType.WITHER);
removeeffects.add(PotionEffectType.INCREASE_DAMAGE);
effects.removeAll(removeeffects); <== ERROR HERE

but i got this error message in the console

[lost matrix]

Arrays.asList returns an immutable List. Use a normal ArrayList instead.

[tardy delta]

new ArrayList<>(Arrays.asList(...))

[lost matrix]

List<PotionEffectType> effects = new ArrayList<>(Arrays.asList(PotionEffectType.values()));

[stiff snow]

ok Thanks... XD my fault...

[smoky oak]

Is there a resource that explains how permissions with numeric values work? The problem i have is that something.<number> says the player doesnt have the permission something

[eternal oxide]

something does not equal something.<number>

if you give a permission something.1 they will not have something

[smoky oak]

how do plugins do it then?

allow everyone access to the command and then check if they have the permission?

[eternal oxide]

you specify child nodes

if you want someone to have something you have to actually give that permission. They don;t get it when you give something.1

a permission does not understand .

[smoky oak]

wouldnt those go in the wrong direction

[eternal oxide]

thats just another character

ie something.1 is a permission, it is not something and 1

[smoky oak]

i see

still

what do you mean by child nodes

[eternal oxide]

in your plugin.yml you can specify parent/child nodes

[smoky oak]

i cant just go and say something.1 child something, something.2 child something, something.3 child something

that would defeat the whole purpose of doing it numerically

[eternal oxide]

if you want them to require something to use a command you have to actually grant that node

then you can check for something.x in the command

[smoky oak]

[heady pumice]

MapView.Scale doesnt seem to be working for me when i create a Map via server.createMap.
I apply the view via MapMeta toa FILLED_MAP, which works fine, scale just isnt reflected.
Do i need to set anything additionally via the meta? No matter what scaling i set in the MapView it just doesnt seem to work

sender.server.createMap(sender.world).also { mapView ->
    mapView.scale = MapView.Scale.FARTHEST
    mapView.isLocked = true
    mapView.addRenderer(ImageMapRenderer(image.getScaledInstance(2048, 2048, 0)))

    ItemStack(Material.FILLED_MAP).also { item ->
        item.itemMeta = (item.itemMeta as MapMeta).also { meta ->
            meta.mapView = mapView
            meta.isScaling = true
        }
        sender.inventory.addItem(item)
    }
    sender.sendMap(mapView)
}

The ImageMapRenderer literally just calls canvas.drawImage, not sure if i need to set anything in there additionally

okay so the scale is set right in the Item, but rendering doesnt seem to adjust in the drawImage function

[paper venture]

Is there a way to understand if a player is hidden for another player?

[tardy delta]

Player#canSee iirc

[smoky oak]

can you test if a string is an integer without using try/catch

like a simple way i dont want to throw a regex at it

[tardy delta]

loop thro each char

[smoky oak]

so regex got it

[tardy delta]

thats not what i said

[smoky oak]

its essentially the same isnt it?

[tardy delta]

the only dif is that regex is slow

but ye your choice

[paper venture]

Thanks!

[smoky oak]

cant you run regex in like 3 modes

[tardy delta]

dunno what that means

[smoky oak]

like flags?

i know that regex can check strings backwards

but not how

[hazy parrot]

what

if you want to check if its number with regex just \d*

but tbh idk why wouldn't you use try/catch

its surely faster then regex

[smoky oak]

what about this one?

if(!new Scanner(strings[1]).hasNextInt()) return false;
int number = Integer.parseInt(strings[1]);

[tardy delta]

a scanner on a string?

[smoky oak]

thats how console input works aint it?

[tardy delta]

thats new Scanner(System.in)

[eternal oxide]

https://www.baeldung.com/java-check-string-number

[tardy delta]

there isnt a a constructor that takes a string

[hazy parrot]

https://github.com/apache/commons-lang/blob/master/src/main/java/org/apache/commons/lang3/math/NumberUtils.java#L1622-L1734 this is how apache does it, and according to online benchmark its faster then try/catch

[smoky oak]

wtf

[hazy parrot]

tbh just use try/catch

[smoky oak]

no im like

how is that faster

[hazy parrot]

https://goksi.tech/​‍‍​⁠⁠​‌‍⁠‌​ ¯_(ツ)_/¯

[smoky oak]

im assuming that coreJava is the try catch thing?

[hazy parrot]

yap

[tardy delta]

meanwhile me https://github.com/FourteenBrush/MathExpressionParser/blob/d2f720fe3b2764840137a82767d66283679b6365/src/main/java/me/fourteendoggo/mathexpressionparser/Tokenizer.java#L104

[smoky oak]

are they using pure regex or a pattern in that test btw

[terse ore]

Is it possible to have more than 2 world borders in a single world?

[smoky oak]

i believe with 1.19 world borders are now per-player but still restricted to 1

its like a really recent change

might be in the snapshot im not sure

[hybrid spoke]

minecraft borders no. custom borders, yes.

but why would you need 2 borders

[hazy parrot]

what

[hybrid spoke]

either per player (whatever moterius said via api) or via packets

[terse ore]

Have you played any Skyblock server?

[smoky oak]

oracle docs:

A compiled representation of a regular expression.
A regular expression, specified as a string, must first be compiled into an instance of this class. The resulting pattern can then be used to create a Matcher object that can match arbitrary character sequences against the regular expression. All of the state involved in performing a match resides in the matcher, so many matchers can share the same pattern.

A typical invocation sequence is thus

 Pattern p = Pattern.compile("a*b");
 Matcher m = p.matcher("aaaaab");
 boolean b = m.matches();
A matches method is defined by this class as a convenience for when a regular expression is used just once. This method compiles an expression and matches an input sequence against it in a single invocation. The statement

 boolean b = Pattern.matches("a*b", "aaaaab");
is equivalent to the three statements above, though for repeated matches it is less efficient since it does not allow the compiled pattern to be reused.
Instances of this class are immutable and are safe for use by multiple concurrent threads. Instances of the Matcher class are not safe for such use.

[terse ore]

they use different borders for every skyblock island

[hybrid spoke]

never really

[terse ore]

I would like to make something like that

[terse ore]

there are multiple islands in the world, and every island has its world border

[hybrid spoke]

oh you mean that many islands are in one world and each player has his own border?

okay yeah, thats just per player

[terse ore]

Is it possible to make in 1.19?

or is it an older version feature

[smoky oak]

btw cipher? do worlds run all on the same thread? i always forget

[hybrid spoke]

not sure, check the api. otherwise https://wiki.vg/Protocol#Initialize_World_Border

[hybrid spoke]

i would think so. only the generation is via workers

[hazy parrot]

they used the one showed on top of paghe

[smoky oak]

k

[hazy parrot]

well, i didn't sent url

https://www.baeldung.com/java-check-string-number

they basically do

[smoky oak]

@tardy delta ur opinion

private boolean hasPermission(final Player player, final int checkValue){
        Optional<String> permString = player.getEffectivePermissions().stream()
                .map(PermissionAttachmentInfo::getPermission)
                .filter(e -> e.toLowerCase(Locale.ENGLISH).startsWith("permission."))
                .findFirst();
        if(permString.isEmpty()) return false;
        try{
            int permValue = Integer.parseInt(permString.get().substring(10));
            return permValue >= checkValue;
        }
        catch (NumberFormatException e){
            player.sendMessage("Please input a valid number.");
            return false;
        }
    }

also im open to suggestions lol

[tardy delta]

remove those finals, this is not C++

[smoky oak]

that aside

[tardy delta]

no

[smoky oak]

we both know thats not what i asked

'what would you do differently aside from the final keywords' if you need it spelled out

[tardy delta]

could use Optional#map but that wont change anything

[smoky oak]

i mean if people give the same permission with different numbers thats not my problem

but point

[tardy delta]

ig that loops thro the players permissions and checks for a permission.X with X higher than checkValue?

[smoky oak]

yuo

*yup

also im checking all perms

cuz of inheritance

thats what im changing rn

[tardy delta]

assuming you dont fuck up with the permission.X i dont see a reason for that try catch

[eternal oxide]

effective permissions on teh player is ALL perms the player has, excluding wildcard

[tardy delta]

let the permissions expert help

[eternal oxide]

unless using Vaul#playerHas for permission checks

[smoky oak]

string to int

people are dumb

[smoky oak]

id like to not depend on other libraries

[eternal oxide]

you should support vault if it's there

its the defacto permission interface

[grim oak]

Dk if this is the right place to ask this, but where and how could I look for work as a plugin developer. How can I find service kind of places to work, and what evidence of experience, and how much of it would they expect to see, and could it also be more beneficial to just work on my own and publish plugins to Spigot?

[tardy delta]

why streaming and then looping over it?

[grim oak]

Where should I look for those people though. BuiltByBit/McMarket seems kind of dead these days

[smoky oak]

might work actually

im not sure if try/catch can be used in a stream method call

[river oracle]

Services

[tardy delta]

you can put try catch in your map

[river oracle]

There is an hiring developer section

[smoky oak]

can you give an example?

[tardy delta]

return checkVal - 1 if its not an int or smth, then filter the ones that are lower than checkVal out again

player.getEffectivePermissions().stream().map(p -> p.getPermission().toLowerCase(Locale.ROOT))
.filter(p -> p.startsWith("permission."))
.map(p -> {
  try {
    return Integer.parseInt(p);
  } catch (NumberFormatEx e) { return checkVal - 1; }
})
.filter(num -> num >= checkVal)
.findAny()```

[smoky oak]

ah

yea i need to make the block around it

what happens with findAny on an empty stream?

does it give an empty Optional ?

[tardy delta]

you probably want that method that returns if the stream found anything

[gleaming grove]

Does Spigot website provides some Rest API that can I use to update Description of my plugin?

[tardy delta]

i forgot the name

[smoky oak]

findfirst?

[tardy delta]

anyMatch

[smoky oak]

instead of filter then ig

[tardy delta]

no anyMatch will return if the stream contains any elements

[smoky oak]

ye i figured

[tardy delta]

so you filtered the ones out that are not permission.X and where X is lower than your value

[smoky oak]

.map(e -> {try{return Integer.parseInt(e);}catch(NumberFormatException ex1){return -1;}})
                .anyMatch(e -> e>= vaultNumber);

[tardy delta]

ah anymatch takes a function?

[smoky oak]

predicate

[rotund ravine]

🤮

[tardy delta]

im thinking if you dont need .count() > 0 instead lol

mb

[smoky oak]

return player.getEffectivePermissions().stream()
                .map(PermissionAttachmentInfo::getPermission)
                .filter(e -> e.toLowerCase(Locale.ENGLISH).startsWith("permission."))
                .map(e -> e.substring(10))//adjust depending on line above
                .map(e -> {try{return Integer.parseInt(e);}catch(NumberFormatException ex1){return -1;}})
                .anyMatch(e -> e>= vaultNumber);

full code for your viewing pleasure

actually i can remove one of those maps ig

[rotund ravine]

What are you even checking for

[tardy delta]

ye

[smoky oak]

permissions, namely numbered ones

in the style of permission.<number>in this example

or rather if the number is equal or higher to the number to check against

[desert loom]

Instead of that comment, you could substitute "permissions." with a variable and use length() on that variable instead of the value 10.

[hazy parrot]

public static boolean canMakeMoreKeys(Player p){
        if(p.isOp()) return true;
        int maxKeys = Integer.parseInt(p.getEffectivePermissions().stream()
                .filter(perm -> perm.getPermission().startsWith("restful.count."))
                .map(perm -> perm.getPermission().split("\\.")[2]).findFirst().orElse("1"));
        return Main.getInstance().getDataContainer().getKeysCount(p) < maxKeys;
    }

This is how i done it in my like really old project

[smoky oak]

ah

i forgot about split

but how do you get around not calling try/catch? saying 'your fault' if someone tried to give restful.count.five?
