[eternal oxide]

check if its your helment

then if check the helmet slot to see if its empty or occupied

then check the clicked slot to see if you are removing teh helmet

[rugged topaz]

@eternal oxide

if you're able to identify the causes that is

more importantly of "and also, if a block regenerates (by plugin) that i've mined, it'll break it again, and give me xp, and continue the loop"

[eternal oxide]

move the for loop inside the if (block.getType() == targetMaterial) {

so it only adds adjacent blocks if this main block is the correct material

ish, remove the ;

you need more tests

[rugged topaz]

the while, or the for

[eternal oxide]

that only tells you if your helmet was clicks, you still need to see if its the one you are wearing

[eternal oxide]

the whole for loop

[rugged topaz]

alrighty

[kindred solar]

i still need help, if anyone can help me i would be happy

this is not working

[eternal oxide]

do you get any errors?

[kindred solar]

no

[rugged topaz]

with that, nothing works

[kindred solar]

talking to me?

[quaint mantle]

why is it boolean

your method return signature

[eternal oxide]

that will tell you if your custom helmet was clicked. Then test the slot, if its not the helmet slot you need to test if the helmet slot is occupied

[quaint mantle]

make it void

[eternal oxide]

@rugged topaz show current code

[split light]

I am trying to add a config file that records the number of times a player gets a special Beer potion item through a command, but I'm having some strange results. The code snippet included runs every time the player receives a new beer using the command: https://pastebin.com/CN481Kt7 I want the value of <UUID>.name.beers to increase by one every time, but that isn't working. Neither is storing data under "name". The results in the config and terminal repeat every time I enter the command, which is when I want the number next to "Beers:" to increase by one. Any ideas?

[eternal oxide]

@rugged topaz ok this issue now is that the original block is already broken. cancel the break in yrou calling event

[quaint mantle]

thats going to lag so hard if it runs often

you need to optimize a lot of your code in there @rugged topaz

[eternal oxide]

It won;t lag, its Async

[rugged topaz]

neither does it run often

too* often

[quaint mantle]

cache arrays, 1 instance of random, cache the itemstacks

[eternal oxide]

no need yet, its not working 🙂

he's close though

@rugged topaz did you change to cancel the block break of the first log?

[rugged topaz]

cancelled the event before calling the func yea

[eternal oxide]

k, now it shoudl work, for the logs

[quaint mantle]

cus thats not how yaml format works

[rugged topaz]

working a lot better now, however the side issue of sometimes getting a block that is two blocks away of the same type rather than touching blocks, and also, if a block regenerates (by plugin) that i've mined, it'll break it again, and give me xp, and continue the loop the latter issue's now resolved

gonna test for the first

seems like both issues were fixed :)

[quaint mantle]

u cant have
id name: 'value' beers: 'value'

[split light]

My problem is a problem, correct.

[eternal oxide]

ok, now you need to instead of checking the name for log or leaves, use Tags

[split light]

is it not possible to have a value next to a subclass with another subclass?

[quaint mantle]

i think you want

id name: beers:

[split light]

yeah

[quaint mantle]

you need to change your keys, they're a bit hard to follow in your code which is what probably got you confused

[split light]

So I guess that would look like, directory wise, "<uuid>.name" AND "<uuid>.beers"

[quaint mantle]

yes

[split light]

I'll try that out. Thanks!

I think I was just being stupid xD

[quaint mantle]

its ok, we all make mistakes

[split light]

One other quick question, how are variable types stored in yaml? I've had trouble putting in a quantity as an int and then getting it out as an int elsewhere in the code

Is it all Strings? Or am I just confusing the spigot API

[quaint mantle]

pretty sure they're manually checked somewhere internally

[rugged topaz]

@eternal oxide so, any other optimizations we're able to make? (i'll work on ay.ngel's rn too) but, is there anyway to dictate the speed of the animation of breaking blocks or no? since it seems the only power i have over how fast the blocks break is a simple .RunTask

[eternal oxide]

You can use a delayed task

[split light]

I'll see first if just simply redoing it properly helps, best not to deal in hypotheticals lol.

[rugged topaz]

async or sync

async ye?

[eternal oxide]

sync

[rugged topaz]

o okay

[eternal oxide]

the breaks have to be sync

[quaint mantle]

yeah, reformatting the yaml how i told u will get it to work 🙂

[deft sedge]

Now I have a new problem

great!

[rugged topaz]

sync meaning one after another?

tbh if i'm bein real with u idek async vs sync when it comes to runnables

[deft sedge]

ItemStack item = player.getItemInHand();
if(!(item.getType() == Material.WRITTEN_BOOK)) {
player.sendMessage(ChatColor.RED + "You have to hold your data book to start the game!");
return true;
}
BookMeta meta = (BookMeta) item.getItemMeta();

            String saturation = meta.getPage(1);
            String thirstRAW = meta.getPage(2);
            String location = meta.getPage(3);
            float HungerF = Float.parseFloat(saturation);
            int Thirst = Integer.parseInt(thirstRAW);

            player.setLevel(Thirst);
            player.setSaturation(HungerF);

[quaint mantle]

if you know for certain the yaml value is an int, then use getInt. if it's not an int, or whatever type you're dealing with, that's an issue with the server owner or whoever is configuring

[deft sedge]

now there are now errors

but it just doesn't work

it's supposed to get the data wout of the book and set the levels (which is substituted for thirst)

and saturation

[eternal oxide]

@rugged topaz In this instance sync means in sync with the server Thread

[deft sedge]

@eternal oxide any ideas?

[eternal oxide]

Async means it runs along side at the same time

[rugged topaz]

ah okay

by 1 instance of random, i'd just move it to the start of the function right

as recommended by @quaint mantle

[quaint mantle]

no, as a global variable

[rugged topaz]

i use rand everywhere

so ur sayin i should instantiate it only once per onEnable?

[quaint mantle]

yeah, use it as a global variable and access that

yes

[rugged topaz]

in that case

[eternal oxide]

yes Random rand = new Random();

[rugged topaz]

does that even make a difference

[eternal oxide]

so its only created once, same with the ItemStack

[quaint mantle]

Random instances are expensive

[eternal oxide]

else it creates a new instance every time. Which takes time and wastes the garbage collector

[quaint mantle]

for the itemstacks that aren't chaning, like the apple or whatever, cache those too

changing*

[rugged topaz]

cache them meaning what exactly

[eternal oxide]

create outside your loop and reuse

[quaint mantle]

make them global variables

[eternal oxide]

so one instance

[quaint mantle]

in the scope of the class, not the method

[rugged topaz]

alrighty

[quaint mantle]

do the same for your blockface array, cache it as a global variable

[eternal oxide]

@rugged topaz is this only for breaking trees, and are teh leaves supposed to break aswell, or only if the first one is broken?

[deft sedge]

@eternal oxide did u see my post?

[rugged topaz]

leaves shouldn't break

or actually

uh

sec

do i also cache new BlockFace[]{BlockFace.UP, BlockFace.DOWN, BlockFace.NORTH, BlockFace.EAST, BlockFace.SOUTH, BlockFace.WEST}?

since it's being instantiated

[eternal oxide]

yes

at class level so its only ever created once

[rugged topaz]

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

i could turn those final

[eternal oxide]

you can also remove your blocksToRemove array now and change it to a counter

a simple int

[rugged topaz]

do you work with intellij

[eternal oxide]

no Eclipse

[rugged topaz]

needa know why sometimes final is suggested and sometimes not, even though most of the time it's allowed

smh okay

[cloud berry]

intellij best ide ™️

[deft sedge]

i agree

[rugged topaz]

https://paste.md-5.net/efuhebapef.cs looking at this now

[eternal oxide]

Move teh BlocksToRemove int inside teh method

it needs to be initialized to zero upon calling the method

[rugged topaz]

mhm but

atomic expression bla bla

[eternal oxide]

you can place it inside the task

its only used inside the task

new ItemStack(targetMaterial, 1) can be moved out

oh no it cna;t 😛

[rugged topaz]

thought about it myself lmao

[eternal oxide]

but it can be moved outside the task

so its only created once per run

place it under targetMaterial

The only part thats not going to work currently is your leaves section

[rugged topaz]

well i don't even have a system where leaves would be able to be broken

but when comes time

it wouldn't be hard to just copy and paste the code from above right

or, we could just do it now

[eternal oxide]

all you'd need to change is the if (block.getType() == targetMaterial) {

[rugged topaz]

o yah, i can do it from there

as of rn

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

ends like this

[quaint mantle]

u want blocksToCheck inside

otherwise if the method is called twice you'll have clashing elements of different runs

[eternal oxide]

if ((block.getType() == targetMaterial) || Tag.LEAVES.isTagged(block.getType())) {```

Yep, blocksToCheck inside so its initialized each call

[rugged topaz]

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

did that, and added a few final's

[eternal oxide]

you will need to test that as the leaves may play havoc with yoru connected idea

[rugged topaz]

if that's the case, when it's implemented i'd be right back here in this channel :)

[eternal oxide]

🙂

[rugged topaz]

thanks for the help over the hour or so tho :) completely fixed all of it

[eternal oxide]

lol, it was only 3 hours 😛

[rugged topaz]

lmaoo

[quaint mantle]

make the apple, sapling and faces static and final

they are meant to be constants

[eternal oxide]

yep, static will ensure they are single instance

[rugged topaz]

done thanks

[quaint mantle]

also i would cancel the task if the player is online

they could easily logout during the async task

is offline*

[eternal oxide]

they could but the Player object won't be disposed of till the task ends

[quaint mantle]

i know, but you could be accessing a stale object for no reason

check via Player::isOnline

[south onyx]

i want to make it so that when i hit a player, they get sent flying forword at a speed of 2, 3, 4, 5 ... 10. The speed will be chosen randomly. Ik you need to use vectors for this, but idk how to.

[eternal oxide]

not really needed as it won;t throw any errors and will just quietly do nothing

[quaint mantle]

set their velocity as their vector of direction, then multiply it via Vector::multiply

[south onyx]

and i multiply it by a random number that i want?

[quaint mantle]

yes, but probably not 2,3,4,5,10, those are massive increments to multiply the velocity by

you'll see yourself when testing

[rugged topaz]

private modifier or no

[deft sedge]

hey anyone free to answer a question?

[quaint mantle]

depends how you're accessing it

private if its only being used in that class, public if its used in many classes, protected if it's only used in that class and child classes

etc

[rugged topaz]

private would further optimize it too

right

[quaint mantle]

no

[eternal oxide]

just protect it

[quaint mantle]

it just follows conventions

[deft sedge]

here is my code

if (args[0].equalsIgnoreCase("start")) {
ItemStack item = player.getItemInHand();
if(!(item.getType() == Material.WRITTEN_BOOK)) {
player.sendMessage(ChatColor.RED + "You have to hold your data book to start the game!");
return true;
}
BookMeta meta = (BookMeta) item.getItemMeta();

            String saturation = meta.getPage(1);
            String thirstRAW = meta.getPage(2);
            String location = meta.getPage(3);
            float HungerF = Float.parseFloat(saturation);
            int Thirst = Integer.parseInt(thirstRAW);

            int ThirstTest = 2;



            player.setLevel(Thirst);
            player.setSaturation(HungerF);

[rugged topaz]

that is code

it takes tthe stuff from a book

[eternal oxide]

what is not workign and any errors?

[deft sedge]

and it is supposed to set the player xp and hunger

no errors

it just doesnt' work

when it says player.set level thirst

[quaint mantle]

Does anyone know how I can create/spawn a structure like a village or stronghold? Please ping me on response

[deft sedge]

it doesn't work

it doesnt' set the level

thirst is meaning the xp levels

making a game where your thirst just uses the xp bar as a puppet

[eternal oxide]

setLevel is the players experience level

[deft sedge]

yea

ik

thirst is just the name of var

and I have checked

it does what I want

I had it print those values out to console

and it did the values

and they were corerect

I did System.out.println(Thirst);

and it printed out the correct number

[quaint mantle]

bump

[floral flare]

criarTabela("info","nome varchar(16), id text");

[deft sedge]

but itdoesn't set player stuff to that number like it should

@eternal oxide

[eternal oxide]

are you sure you want saturation? Thats not food level

[deft sedge]

?

i want to set the food level

[floral flare]

in this case, to store text

[eternal oxide]

then void setFoodLevel​(int value)

[deft sedge]

ok but y does the xp set not work?

[eternal oxide]

what value are you setting for exp?

[deft sedge]

it is a simple integer

just doeing set level

[eternal oxide]

exp is a float

[deft sedge]

o

but if i make it float

[quaint mantle]

bump

bukkit impl for exp is wack

[eternal oxide]

level is total levels, exp is how far to next level

[quaint mantle]

look up some exp tools, ive seen some people make some on bukkit and spigot that lets u control the exp like normal

[deft sedge]

it says it requires int

?

not right?

@eternal oxide

[quaint mantle]

(int) thirst

[eternal oxide]

setExp is a float. setLevel is an int

[deft sedge]

well don't I want setexp

srry set level

bc i want to change levels

[eternal oxide]

are you trying to set their current level or the exp till next level?

[quaint mantle]

then just make your float an int

[eternal oxide]

ok level

[deft sedge]

ok

but it was int from the start

i only changed it bc u said to

[eternal oxide]

what value are you setting to it?

[deft sedge]

like 2

[quaint mantle]

float is for setting the exp, int is for the level

[quaint mantle]

bump, can someone plz help

[eternal oxide]

once you set level try calling player.sendExperienceChange((float) 1);

[deft sedge]

ok

[quaint mantle]

u need to change chunk generation to your own

[quaint mantle]

i dont want to make it generate with chunks

i just want to generate one on the spot

in existing chunks

[south onyx]

how do i get a 10 block radius around a entity
bc what im trying to do is teleport an entity to a random location that is in the 10 block radius of his old location

[quaint mantle]

loop between every axis u want, for x amount of blocks/distance

[eternal oxide]

or generate a random vector

[deft sedge]

@eternal oxide THanks for all the help! It works

[wet breach]

might want to use Math.abs as well for the radius check

makes things easier when you are not dealing with negatives 😛

[young knoll]

I would just add a random number between -10 and 10 to their x and z, then either get the highest block y at the new location or scan up/down for a free space

[quasi epoch]

Hey guys, looking for someone who knows about command blocks

Essentially all I need is a command block triggered when a player respawns, and when they join the server for the first time

[young knoll]

We deal with plugins here mostly

You may want to look into that, or ask in the minecraft commands discord

[north niche]

im saving blockdata in a txt file like this

bl.getBlockData().getAsString()
//where bl is a valid defined BLOCK

now i got the block data string like this

minecraft:oak_stairs[facing=south,half=bottom,shape=straight,waterlogged=false]

now how to set block with this blockdata

[quaint mantle]

idk if there's a way bukkit can parse that

you might have to parse it yourself and set the data yourself

[north niche]

so there is no other ways ?

[tough zephyr]

@quaint mantle Just do a for loop on world.getEntities()

instanceof RabbitWhateverClassName

The rabbits should have a ticksLived function

Just use that to tell how many ticks have passed since their creation

[tough zephyr]

@quaint mantle I think you can re-set the ticks lived?

With Spigot API that is

[dusty herald]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Entity.html#setTicksLived(int)

[tough zephyr]

Yeah that'll work perfectly

[outer sorrel]

how would i get the player previous position from a move packet? (PacketType.Play.Client.POSITION)

[quaint mantle]

or grab the chunk of every player, add it to a set (so you only have unique chunks), then loop through those chunks and get the rabbits in those chunks then do whatever u want with them

[regal dew]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerMoveEvent.html, be careful with it as its called a lot per tick

[outer sorrel]

im using packets

[quaint mantle]

to make it so each rabbit only does it once they've lived for 8k ticks, you can keep track of their uuid and mark when you've first tracked them (mark the time), then when you loop through them again, check to see if the current time minus the initial track time is >= 8k

then mark them as 'marked' or something so u know they've already dropped dirt, otherwise they'll drop every 8k ticks

[regal dew]

The packet doesnt contain the previous location, for that you need to do some magic yourself

ie store it

[outer sorrel]

ok thanks

[lost matrix]

There are 2 possible approaches:
First:
Extend the nms rabbit and overwrite the tick method. (Would need to register the rabbit in the IRegistry which has gotten quite complex)

Second:
You create one runnable that runs about every 20 - 40 ticks because you dont need a 50ms precision i suppose.
Then listen for the ChunkLoadEvent, get each entity from the chunk, filter the rabbits and add it into a Map<Rabbit, Long>.
Remove the rabbit in the ChunkUnloadEvent. You can make the timer persistent if you use the rabbits PersistentDataContainer. (Which you should do)

If you want a better performance than you can take a look at section 3 of this tread:
https://www.spigotmc.org/threads/guide-on-workload-distribution-or-how-to-handle-heavy-splittable-tasks.409003/

[outer sorrel]

how would i do this lol, my brain is mush rn

[lost matrix]

Take a look at this:
https://gist.github.com/Flo0/7b98ae3234c4fc0edd6c3ce4a325e5f3

Its the lesser performant way.

You should be able to figure that one out by looking at the run method.

[maiden briar]

What is the best way to save an ArrayList (with uuid's) into MySQL?

Pls ping if you know the answer

[lost matrix]

Depends on the relation of that data.

[maiden briar]

I have my regions, and they have members

List<UUID> members

[lost matrix]

So relational databases are designed for one value per column.
If you want the quick and dirty way:
Serialize the List to a single String.

The normalized design way would be to create a new table for each region.
Thats what relational databases where defined for.

But if you are absolutely certain that you will always just have UUIDs in there then its possible to just join the UUIDs with '\0' or
something like that and store them as a single value.

[maiden briar]

Yes then I think I will store as one single values, thanks

Then I need to choose "VARCHAR"?

Oh and I have seen MySQL has "ENUM", can't I use that?

[quaint mantle]

can anyone help me setting up leaderboard using leader heads plugin in bedwars1058

[lost matrix]

Is a UUID an Enum?

[maiden briar]

No but save in an ENUM

Because you can save up to 60000 custom strings

[lost matrix]

Why not just go for varchar or nvarchar? The limit is 2GB per String...

[lost matrix]

Oh. You mean one enum value per UUID. Thats an interesting idea...

[maiden briar]

Yes

Indeed

[lost matrix]

But... then you would need to define a new enum type for each region. And then re-define it each time the list changes.

[lost matrix]

I dont think it would work well tbh

[maiden briar]

Hmm ok

[vague mason]

Is anyone here database expert?

I have a really stupid question...

I mean it seems genies to me be I never seen anyone to do this...

That's why I think it's stupid...

[ivory sleet]

?ask

[queen dragon]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply.

[vague mason]

I'm going to work on password manager and like normal way is to create users, passwords and user_passwords tables.
But I was thinking when billions of passwords will be saved. Wouldn't be better if I create new table for each user?
So database would be able to find password much more faster then looking them from billions of passwords....
So each user will have their own table with their own passwords.
and finding the right password from one table with 30ish passwords will be much faster then looking for user password from table with billions of passwords...(edited)
so I can just do SELECT * FROM <username>; to get all passwords from this specific person.
Instead of SELECT * FROM passwords p JOIN user_passwords up ON up.password_id = p.password_id JOIN users u ON u.user_id = up.user_id WHERE u.username = <username>;
Also deleting and retrieving passwords would be much more faster.
But I never see anyone to do this.... So that's why I'm asking...
Also if user remove their account I can just delete him from user tabel and also delete their table which name = their username.
Much faster then finding all his passwords in table with millions of data and deleting each one password.

[ivory sleet]

idk

[ivory sleet]

user per table designs are usually not so manageable from what I've heard

[vague mason]

I mean users will be still saved in one table

but for passwords every user will have their own table

[main dew]

I have problem I need protocollib 3.5 but I can't find this

[ivory sleet]

idk never seen anyone due to lack of maintainability but why not try it so you can experience the cons yourself

[lost matrix]

Thats just how relational databases work. Relational collections become their own table...

[vague mason]

So then it's just better if I make every table for every user separately by myself?

Like I will never need to look for passwords from 2 or more users at the same time.

so it makes sense that it's better to just separate passwords

[lost matrix]

No. Build your data after those principles:
https://en.wikipedia.org/wiki/Database_normalization

[vague mason]

Yeah normal is the first way but it seems slower for me.

I mean first option has pros.

for example it will allow users to share passwords between each other

But if I don't need that then it might be better to create table for each user.

[main dew]

how to add protocollib version 3.5 to a local repository?

#help-server
This channel is for developer support. Hence its name help-development

[quaint mantle]

ohkk

umm can someone explain me about PersistantDataContainers ?

[ivory sleet]

yeah

its a way to interact with the persistent nbt stored in tile entities and itemstacks through api

or well PersistentDataHolders

[quaint mantle]

so what does primitative and complex of a object mean exactly ? (in PersistentDataType)

[ivory sleet]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/persistence/PersistentDataType.html read here Ig

[quaint mantle]

are they somehow linked together or something ?

[ivory sleet]

well I mean

there exists two types of every primitive sort of, a boxed and an unboxed type

probably a way to convert between those I guess

[quaint mantle]

ok

[ivory sleet]

or maybe not

well just read the javadoc there

explains in a more plausible manner

[quaint mantle]

but won't the methods toPrimitive and fromPrimitive be useless if there is no way to convert between them ?

[ivory sleet]

public class UUIDTagType implements PersistentDataType<byte[], UUID> {

         {@literal @Override}
         public Class<byte[]> getPrimitiveType() {
             return byte[].class;
         }

         {@literal @Override}
         public Class<UUID> getComplexType() {
             return UUID.class;
         }

         {@literal @Override}
         public byte[] toPrimitive(UUID complex, PersistentDataAdapterContext context) {
             ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
             bb.putLong(complex.getMostSignificantBits());
             bb.putLong(complex.getLeastSignificantBits());
             return bb.array();
         }

         {@literal @Override}
         public UUID fromPrimitive(byte[] primitive, PersistentDataAdapterContext context) {
             ByteBuffer bb = ByteBuffer.wrap(primitive);
             long firstLong = bb.getLong();
             long secondLong = bb.getLong();
             return new UUID(firstLong, secondLong);
         }
     }

its probably more understandable if you look at the example provided where T and Z differs

byte[] would be how it's stored

the you would use UUID to interact with it

[quaint mantle]

I c

that's make sense

ty, also I read docs and try to ask questions when I don't rlly know thing

[ivory sleet]

yeah

[lost matrix]

This is one example of how to use the PersistentDataContainer for a simple counter.
https://gist.github.com/Flo0/473919e547c9dce8c49227a019210155

[abstract relic]

PersistentDataContainers

are so cool

i love em

[ivory sleet]

idk

its fine

[lost matrix]

If we only had a way of properly storing data in any block...

[ivory sleet]

that'd be excellent

[quaint mantle]

um, I understand what is PersistantDataContainers but was confused with how to get the Values and set the Values

[ivory sleet]

PersistentDataContainer#set and #get

[lost matrix]

This example shows how to get and set values

[ivory sleet]

then you need a namespaced key

which acts like any other key

[quaint mantle]

I read the docs, and that PersistentDataType was the confusing part not the methods of the DataContainer

[ivory sleet]

and then the PersistentDataType is what type you want to store it as

[quaint mantle]

lol I thought its an image xD

[ivory sleet]

the most interesting types which you want to use is probably either PersistentDataType.INTEGER or PersistentDataType.STRING

[lost matrix]

Oh ok. Those types are pretty much type converters from primitive to complex values. But i think conclure explained the implementation already.

One could actually write a Library for some custom persistent data types like PersistentDataType<byte[], ItemStack> or <byte[], ItemStack[]> or <byte[], Inventory> etc

[ivory sleet]

oo

would be awesome if one would create such a thing

[lost matrix]

Because storing an entire inventory in an ItemStack is a simple way of doing backpacks for example.

[ivory sleet]

indeed

[quaint mantle]

oh ok ty for the information, @lost matrix and @ivory sleet,
have a good day 😄

[ivory sleet]

u2

[quaint mantle]

another question does the Tag of an item, entity still remain even if the server restarts ?

[ivory sleet]

yes

persistentdatacontainers holds persistent data 😄

[quaint mantle]

Nice

[grave kite]

Hi, is it possible to modify all the chat messages sent to a player including messages from other plugins?

[lost matrix]

Yes

[grave kite]

Is there an event for that? How do I specify that the plugin should go after all the others?

[lost matrix]

https://wiki.vg/Protocol#Chat_Message_.28clientbound.29

Probably better on the proxy layer

[grave kite]

I'm not so good at plugin development, but it does seem a bit low level. Doesn't spigot have some kind of abstraction for that?

[lost matrix]

I dont think so. But the abstraction is provided by ProtocolLib

[grave kite]

ok, thanks

[quaint mantle]

I cant disable invenoryclick event

[lost matrix]

Yes you can

[quaint mantle]

Nevermind a hadnt closed my switch

No

[quaint mantle]

I cannot

[lost matrix]

Yes you can. Generally speaking.

[quaint mantle]

f

You can disable inventoryclickevent (e.setCancelled(true);)

thats exactly what I'm doing

and fuck you automod

[opal juniper]

dont be toxic

@quaint mantle just send the code where u use the inventorycloseevent and are you czech?

[quaint mantle]

We had the discussion a few days ago xD

about the event or czech xd

Czech

oh xd

huh?

just send the code where u use the inventorycloseevent

[quaint mantle]

Nah I just forgot to register events in the main class

okay

F

anyway thanks

i mean its always the register event in main class xd

[sage dock]

how to send broadcast message only to a specific server exactly where the person who writes is located (bungeecord)

[quaint mantle]

like to all players that are on the server where player texted

[sage dock]

🤔

okey

[quaint mantle]

okay ill send u a code

@EventHandler public void chat(ChatEvent e) { ProxiedPlayer playerWhoWritedInChat = (ProxiedPlayer) e.getSender(); for (ProxiedPlayer proxiedPlayers : getProxy().getPlayers()) { if (proxiedPlayers.getServer().getInfo().getName().equals(playerWhoWritedInChat.getServer().getInfo().getName())) { // Players are on the same server as player who writed in chat. } else { // Players aren't on the same server as player who writed in chat. } } }

[maiden briar]

Why do I get https://api.mojang.com/user/profiles/"<UUID>"/names as URL with that "" ?
new URL("https://api.mojang.com/user/profiles/" + UUID + "/names");

[quaint mantle]

try using only one () in new URL() like that new URL("https://api.mojang.com/user/profiles/" + UUID + "/names");

okay you edited it

[maiden briar]

Yes I found that out

But that is not the solution

[quaint mantle]

could you send whats in the UUID

like what prints out

if the "" isnt in the uUID

[maiden briar]

[12:19:34] [Server thread/WARN]: java.io.IOException: Server returned HTTP response code: 400 for URL: https://api.mojang.com/user/profiles/"63c8889e90874e1fb5e958a8e86e34f1"/names

[quaint mantle]

how do you get the uuid method

[maiden briar]

With an String

I will print the UUID string for you

[quaint mantle]

okay

[maiden briar]

[12:20:43] [Server thread/WARN]: java.io.IOException: Server returned HTTP response code: 400 for URL: https://api.mojang.com/user/profiles/"63c8889e90874e1fb5e958a8e86e34f1"/names```

[quaint mantle]

okay show me the code when you set the value to the string

seems like the "" is somewhere in uuid setting

[maiden briar]

public static String getUUID(Player player)
{
    try
    {
        URL uuid = new URL("https://api.mojang.com/users/profiles/minecraft/" + player.getName());
        BufferedReader in = new BufferedReader(new InputStreamReader(uuid.openStream()));
        return new JsonParser().parse(in.readLine()).getAsJsonObject().get("id").toString();
    }
    catch(IOException e)
    {
        e.printStackTrace();
    } 
    return null
}

        BufferedReader in = new BufferedReader(new InputStreamReader(uuid.openStream()));
        return Bukkit.getPlayer(new JsonParser().parse(in.readLine()).getAsJsonObject().get("name").toString());
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }

    return null;
}

[lost matrix]

Why tf would you query the mojang server when you got a Player object??

[maiden briar]

Because players have different UUID's in offline mode unfortunately

[quaint mantle]

well if he wants uuid and he doesnt have online mode

yeah

new URL(("https://api.mojang.com/user/profiles/" + UUID + "/names").replaceAll("^"|"$", "")); remove the double () here too

[maiden briar]

It's under bungee

[lost matrix]

Oh god...

[maiden briar]

Can't

[quaint mantle]

oh yah sry my bad

didnt notice the replace method that needs it

[maiden briar]

😄

[quaint mantle]

when you use the an getPlayer() method what do you put inside the an argument?

p.getUniqueID().toString()?

[maiden briar]

Nope

[rotund ravine]

what

[maiden briar]

Converted uuid's for the string above

[eternal oxide]

Bungee should be Online, ALWAYS. Servers set to offline.

[maiden briar]

Yes Bungee is online, Spigot is offline, this plugin is running under spigot

[eternal oxide]

The servers will get the players UUID from the bungee server

[maiden briar]

Ok how would I do that?

[rotund ravine]

You don't do anything, it'll already be pushed to the server.

[eternal oxide]

its how it works normally when you correctly configure bungee

[rotund ravine]

Authentication happens at bungee and the uuid and ip gets forwarded.

[maiden briar]

But the problem is that this plugin is running UNDER SPIGOT

[eternal oxide]

the UUID still comes from bungee

[quasi epoch]

Looking for someone to make a plugin;

Custom drops from each crop type, configurable by biome

Let me know if possible and what price $$$ you would like!

[eternal oxide]

read the post installation section https://www.spigotmc.org/wiki/bungeecord-installation/

[maiden briar]

Yes I don't what to do with it

[eternal oxide]

do with it?

[maiden briar]

I don't need to post

[eternal oxide]

I'm not understanding you

[maiden briar]

I already configured bungee

This is the main problem:

[12:20:43] [Server thread/WARN]: java.io.IOException: Server returned HTTP response code: 400 for URL: https://api.mojang.com/user/profiles/"63c8889e90874e1fb5e958a8e86e34f1"/names```

[eternal oxide]

You havn't if your servers are getting offline UUIDs instead of Authenticaed ones from Bungee

[maiden briar]

That "" in the URL

Yes I need authenicated one from bungee, and my plugin is under spigot

[eternal oxide]

Your spigot will use UUIDs from Bungee

[maiden briar]

The problem is simple: Bukkit.getPlayer(UUID.fromString() returns null

[eternal oxide]

if you have offline UUIDs on yoru spigot then your setup is wrong. You are allowing direct connections and not going through bungee

[opal juniper]

When i kick the player, the reason gets printed to console, can i stop this?

[maiden briar]

I did before player.getUniqueId.toString

[maiden briar]

How to fix that?

[main dew]

how to add protocollib version 3.5 to a local repository?

[eternal oxide]

IF your bungee is setup properly player.getUniqueId() will return a Bungee Authenticated UUID.

Hmm and in Spigot you don't have ProxiedPlayer???

change version

[maiden briar]

The problem is that I need it in spigot

[eternal oxide]

proxied player is bungee not spigot

[quaint mantle]

just let him do it the way in url

[maiden briar]

I need the UUID in spigot

[maiden briar]

Exactly

[eternal oxide]

the UUID is already IN spigot

[maiden briar]

But the "" are the problem

[maiden briar]

Yes the OFFLINE UUID

[eternal oxide]

no

[quaint mantle]

YES

[eternal oxide]

Online Authenticated. Thats precicely what Bungee does

[quaint mantle]

if he doesnt want to use online mode for both then he doesnt have to

[eternal oxide]

Bungee shoudl alwasy be online or you have no authentication/security at all

[maiden briar]

The problem started with how to remove "" in the URL and now we are discussing 20 minutes and we didn't got anything further

[quaint mantle]

ill jjust try to fix it with the code you sent me

[maiden briar]

Yes thanks

[eternal oxide]

Is yoru bungee server set to Online or Offline

Bungee, not spigot

[maiden briar]

You can send it to me in DM, I have lunch now

[main dew]

I must use old vesion (this plugin use old version protocollib)

[maiden briar]

Online

[eternal oxide]

Then I am correct and you are doign it all wrong

With Bungee set to online, your spigot servers get ONLINE UUIDs from Bungee

[opal juniper]

then just change the version, if not just add it is an itelllij dependency

[eternal oxide]

If you are getting offline UUIDs in Spigot then your servers are exposed and players are connecting directly to them with no authentication

[main dew]

the old version has a different record, I would have to change from 100-200 lines of code

[weary geyser]

@maiden briar s.replaceAll("[\"]", ""); that should work if it doesn't work I'm just really shitty with regex

do that on the url string

or whatever

[main dew]

How I can add libary to maven?

[eternal oxide]

@maiden briar there is a full section about Online UUIDs and bungee in the setup guide I linked you - DATA CONSISTENCY WITH UUIDS & IP FORWARDING:

You don;t need any of your code when you can simply use the player UUID

Potion effect heal on a player?

player.getPotion what then?

[eternal oxide]

player.addPotionEffect(new PotionEffect(PotionEffectType....

[acoustic tapir]

thx

have a error why ?

[limber dust]

you need to add more

[drowsy helm]

i use my middle finger for ' interesting how others type lel

[weary geyser]

)

[ivory sleet]

pretty sure there's no such constructor

[limber dust]

like seconds, amplifier

wellll

ticks

not seconds

[weary geyser]

I use my index lol

[acoustic tapir]

what comes the behind? so what numbers

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/potion/PotionEffect.html#<init>(org.bukkit.potion.PotionEffectType,int,int,boolean) or any of the constructors you find there

[limber dust]

new PotionEffect(PotionEffectType.HEAL, int, int));

[eternal oxide]

look at the javadoc I linked. they are all named

[limber dust]

^

[acoustic tapir]

thx

[limber dust]

see i wish i had the docs on speed click but don't

i have intellij open set to a keybind though XD

[eternal oxide]

web browser for me. the search is great. I wish MD_5 added it to the bungee docs too.

[ivory sleet]

it always says javascript disabled when I'm on the bungee docs

[wide galleon]

How can I detect if the player enters a new chunk?

[eternal oxide]

didn;t I tell you this yesterday?

[wide galleon]

i dont really understand that

[drowsy helm]

if you cache their location you can divide it by 16

[eternal oxide]

other than writing the code for you it was really simple

[round finch]

where do i learn 3D Math for unique shapes ?
so i can generate unique shapes with loops?

[acoustic tapir]

how do I do a query of the heart you that when the heart is full you instantly die ?

who has a java class that I can look at

[drowsy helm]

shapes are all just 3d graphs, so I'd start with polynomials

[eternal oxide]

public boolean isNewChunk(Location from, Location to) {
    if (convertToChunk(from.getBlockX()) != convertToChunk(to.getBlockX()) {
        //new chunk
    }
    //repeat to test getBlockZ
}

private int convertToChunk(int value) {
    return (int) Math.floor(value) >> 4;
}```

[acoustic tapir]

should that be for me?

[eternal oxide]

thats for @wide galleon

[drowsy helm]

no its not nick

[acoustic tapir]

ok

[drowsy helm]

nick what do you mean query a heart

[round finch]

i really took a linking to wordedit generate command
i wanted to do 3d geometry :D

[acoustic tapir]

a choice of hearts and when they are at 10 hearts one should die

[drowsy helm]

well 3d geometry falls under a lot of different graph types, it really depends on what shape you want to make

[wide galleon]

tyssm and where do I put my code?

[drowsy helm]

just check their health on heal event

[round finch]

thank you for sharing your fact

[eternal oxide]

you use the getFrom() and getTo() in the player move event

[drowsy helm]

ngl i never thought of right shifting the x and z

that is genius

[eternal oxide]

just looks cleaner

[drowsy helm]

i just divide by 16 and floor

[acoustic tapir]

Coincidentally, we also have here who can speak German and who help me in the talk because I'm not an English professional

[wide galleon]

where would I put that?

[limber dust]

why does everyone ask that XD

[eternal oxide]

Sorry, I wrote the code you need. I'm not willing to write your plugin 😭

[drowsy helm]

wherever you're checking it

critical thinking

[round finch]

ok what if i did 3d grap stuff with some doubles

would i round it up to fit in the grid of Blocks to make Lines?

[drowsy helm]

yes it would floor it

if you're working with blocks

[round finch]

yeah

that my idear

[drowsy helm]

its just a matter of iterating through your bounds and entering the x,y,z coords into your formula

[round finch]

i literally paided a guy on fiiverr 50$ 🙂
and he wasn't much of help with learning me to understand

he even claimed to be a professer

[drowsy helm]

dont use fiverr

its horrible

[round finch]

and software engineer

[drowsy helm]

you can learn all that stuff on youtube for free

[round finch]

ye why spend money? then you can save right xd

[ivory sleet]

fiverr lol

[drowsy helm]

thats exactly it lol

[ivory sleet]

you could have just thrown that money right in the trashcan

[round finch]

or donate it to random person XD

[quaint mantle]

Is there a method to quickly convert a string to an EntityType

for example

"zombie" --> EntityType.ZOMBIE

I do not feel like switching and casing every entity

or mapping them

[eternal oxide]

EntityType.valueOf(String)

[quaint mantle]

thanks

[ivory sleet]

might want to use something like Enums.getIfPresent(EntityType.ZOMBIE,"zombie").orElse(null); I think as that would avoid the exception thrown when an invalid input (string not matching one of the enum constants case sensitive) is passed.

[quaint mantle]

pass it as lowercase then lol, I think 🤔

[ivory sleet]

?

you'd have to pass it as uppercase

[quaint mantle]

hmmm

then I am reading the source of valueof wrong then

[drowsy helm]

isnt there a default enum function for that

[ivory sleet]

no but it would for instance
return EntityType.ZOMBIE if and only if you passed "ZOMBIE"

[quaint mantle]

no idea... I am new to the spigot API hahaha

[drowsy helm]

not spigot just java

[ivory sleet]

well this touches default java as well

Enum#valueOf

[drowsy helm]

yeah Enum#valueOf

just pass string as uppercase

and try catch block

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/EntityType.html#valueOf(java.lang.String)

[quaint mantle]

hmm

enumerations are annoying

[drowsy helm]

not really

its pretty straight forward

[quaint mantle]

i dont think so

they are good

[ivory sleet]

enumeration is a different thing

or if we're talking about Enumeration<E>

[quaint mantle]

nah I was stating something offtopic

haha

[ivory sleet]

dont confuse enums with enumerations though

[drowsy helm]

believable

[quaint mantle]

are the enums constants?

[ivory sleet]

ehm they're not enumerations if that's your question

[quaint mantle]

I do not know that standard for enums

[ivory sleet]

Im confused as well

[quaint mantle]

but constants are capitalised

java has weird rules

like flipping a domain 😑

[drowsy helm]

you cant have instances of enums if that's what you mean

they are stateless

[ivory sleet]

unless we make them stateful 😄

[quaint mantle]

More like Java has strange conventions that you can break in exchange for being humanity's worst supervillain

Does anybody know how do i chat with BungeeCord & Spigot with CustomPluginMessages (having one spigot plugin & and one bungeecord plugin) i want the bungeecord plugin to get message from spigot when a event happens. but idk how to do it. (https://www.spigotmc.org/wiki/sending-a-custom-plugin-message-from-bungeecord/) this wiki didn't help me.

[ivory sleet]

plugin message channels

or something like redis

[quaint mantle]

no i dont want like spigot to connect player to another server

Redis is the solution to every plugin problem

[ivory sleet]

wat

[quaint mantle]

i want likesomething like authme uses to disable commands like (/server) when logging in

[round finch]

how do you convert math formals like this into 1/1?
plus i don't have any understand of advance math just the basic

any online converters?

[eternal oxide]

The /server command requires a permission and players don;t have it when connecting

[round finch]

i'm trying to turn the math fomauls into different format
so i can easily make shapes using the new formats fx like this 1/1

[quaint mantle]

wtf

What type of formulas do you want to convert, and what do you want to convert them into?

[round finch]

isn't there website to convort math fomauls into the format i'm looking for?

[quaint mantle]

well yeah they dont but if they are loginning as the player that has it then they can access ti

What are you looking for

If you mean a rational form then look at Wolfram Alpha

[eternal oxide]

If your Bungee is online and your servers are correctly configured they can only log on as themselves

[quaint mantle]

yes but im making an plugin

and i want just to know how to do the custom plugin messages

[ivory sleet]

plugin message channels or redis still :]

[eternal oxide]

It just seems you are looking for a way around something you don;t need to avoid

[gentle orchid]

hi

[quaint mantle]

hey

[gentle orchid]

can i make server ?

[quaint mantle]

okay so how do i send plugin message channels?

yes u can

[gentle orchid]

how

[quaint mantle]

try server.pro if you want free

[eternal oxide]

The tutorial has everything you need for messaging channels.

[gentle orchid]

ok

[quaint mantle]

which tutorial?

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/#forwardtoplayer

this?

[eternal oxide]

Yes

[quaint mantle]

okay ty

[ivory sleet]

Bukkit.getMesseger().regiserOutgoingPluginChannel(pluginInstance,channelName)

then https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/plugin/messaging/PluginMessageRecipient.html#sendPluginMessage(org.bukkit.plugin.Plugin,java.lang.String,byte[])

[quaint mantle]

do i need to do msgout.writeShort(123);?

[ivory sleet]

no why?

[quaint mantle]

its in tutorial so just asking if i can delete it

[eternal oxide]

https://www.spigotmc.org/wiki/bbcode.3202/archive

[opal juniper]

Can you clear the resource pack that a client has cached for your server?

[young knoll]

Not with a plugin

You can change the sha

[round finch]

this a example of the format i don't want

i want it to be convert into a format where it is on 1 line like this
x = -b+-b^2-4^ac / 2a

[quaint mantle]

wtf

[young knoll]

Quadratic formula

[ivory sleet]

ByteArrayDataOutput out = ByteStreams.newDataOutput();
out.witeUTF("message");

Optional.ofNullable(Iterables.getFirst(Bukkit.getOnlinePlayer(),null)).ifPresent(player -> {
  player.sendPluginMessage(pluginInstance,messageChannel,out.toByteArray());
});``` @quaint mantle smtng like this I believe

[quaint mantle]

How will you load these formulas? As an image file?

[round finch]

any website there does that?

[ivory sleet]

ofc when you read it you'd need to call #readUTF or smtng as opposed if you'd write a short you'd have to call #readNextShort or smtng

(if you wanna read the message)

[quaint mantle]

why you using the quadratic formula is another question 😆

@ivory sleet okay ill try it

[ivory sleet]

also some coding configuration on the proxy side might also be needed

idr

[round finch]

i don't what the word of the concept or phrasing of the thing i'm looking for

[ivory sleet]

iirc there's smtng called photomath

[quaint mantle]

If you have a single formula you want to change, do it manually. Just put parentheses around the numerator and denominator and put a / between them.
If you have multiple formulas you want to change then you need a library that can do symbolic math

If you are saying that you want to convert these formulas in a java program, then you need to be willing to get both libraries that read those formulas from image files or whatever and put them into symbolic mathematics libraries.
If this is just some mathematics homework then do it manually.

An example of such a library is SymPy (a Python library)

[round finch]

i just have no real math experience so i wanted to simplify it into one line

[eternal oxide]

Just write it out. Its fairly simple

[quaint mantle]

how is python going to help with java

[worn tundra]

That's why it's an example.

[quaint mantle]

o

[quaint mantle]

It does not look like this was a Java question

Looks more like math homework

it should be pretty easy, you could do it in a method, or class based

[round finch]

the idea is i need to do math stuff
and make 3d minecraft block shapes

[quaint mantle]

I do recommend you use a separate class for it though, means you can reuse it

[quaint mantle]

interesting

[round finch]

but i dont understand Quadratic formulas or symbolic math

[eternal oxide]

ask questions on what bits you don't understand

Java has a full Math class for all of that

[round finch]

it look like Alien language to me

[ivory sleet]

I think its like a "beutification" of ax^2 + bx + c = 0 (a != 0)

[round finch]

so i wanted to translate any Quadratic formula into something i understand

[quaint mantle]

Then you only need a few formulas. You can easily rearrange them with high school mathematics. In java the quadratic formula would be something like this:
int x1 = (-b + Math.sqrt(Math.pow(b, 2) - 4\*a\*c))/(2*a) and int x2 = (-b - Math.sqrt(Math.pow(b, 2) - 4\*a\*c))/(2*a)

[ivory sleet]

and if you're only working with the math maybe static import Math class to reduce verbosity btw

[cinder thistle]

good god

flashbacks of converting formulae to java

[quaint mantle]

If it's mainly geometry then there are probably also libraries that have functions with these formulas built in

[sleek pond]

flashbacks to 7th grade algebra

[round finch]

why does math have such complex Quadratic formulas instead of (-b + Math.sqrt(Math.pow(b, 2) - 4*a*c))/(2*a)

[cinder thistle]

although @waxen plinth's crunch would probably be able to parse it quite well

[quaint mantle]

It's concise

[round finch]

it make my brain yeet off and into crazy

[cinder thistle]

it's a lot more readable ig

as soon as you start writing it in java it's ass af

gotta have comments linking to the formula on google

[quaint mantle]

The quadratic formula is so well-known that you can just write //quadratic formula and most programmers would get the point

[cinder thistle]

wrong channel

The quadratic formula has two solutions when sqrt(b^2 - 4\*a\*c is greater than 0, one solution when it is zero and no real solution when it is less than zero

[maiden briar]

player.connect(entry.getValue());
//try and catch
Thread.sleep(10000);
SpawnManager.forwardToSpawn(player);
return;

The problem: I want that the player get connected immediately and then after couple seconds the forwardToSpawn is called, but this will let both wait and then do both things at the same time

[ivory sleet]

thread sleep 😮

[eternal oxide]

Never sleep main thread

[paper viper]

oh god please no

lol

[young knoll]

Use a runnable

[round finch]

do time check

[paper viper]

runnablefuture

(:

@ivory sleet

would approve

[maiden briar]

Ok

[ivory sleet]

noice

[paper viper]

wait not runnablefuture

i forgot what its called

mi brain ded

[ivory sleet]

ScheduledRunnableFuture ?

[paper viper]

CompletableFuture

[ivory sleet]

CompletableFuture?

ah

yeah

[paper viper]

yea lol

[round finch]

there is something about never make thread sleep cus it in not good in spigot or something idk
i forgot🤔 thb idk

[paper viper]

???

[maiden briar]

Ah the problem was quite simple: I didn't need to get the serverInfo from the player, I needed to use the correct serverInfo

[ivory sleet]

ok

[sleek pond]

that's just general bad advice

never sleep the main thread

[paper viper]

Never use sleep

[ivory sleet]

well thread sleep is fine

[paper viper]

for this case

[ivory sleet]

but on the server thread it should be avoided

[paper viper]

not should, always

lol

unless you going to make some backdoor shit

[cinder thistle]

wdym

[ivory sleet]

I mean I could think of like one usage where it would be useful

[cinder thistle]

why not sleep the main thread

sounds good

[ivory sleet]

troll plugin or some random shit

[paper viper]

lol

[cinder thistle]

ultra performance

100% multithreaded $19487819

[paper viper]

ur dog is so tall smh

[quaint mantle]

Nobody gets my code 😎

[ivory sleet]

ik right

[paper viper]

show me ur code then lmao

[round finch]

any tip for a math dumi like me?

[quaint mantle]

1 sec

[round finch]

phone autocorrects.. jikes

[paper viper]

@ivory sleet have you used completablerunnable before?

[ivory sleet]

wat

no

pretty sure thats not a thing

[paper viper]

or not that

lmfao

i keep mixing them up

[ivory sleet]

yeah lol

[paper viper]

I meant runnablefuture

[ivory sleet]

yes

Its useful if you're making an expiring cache but then we do have libs like caffeine and guava

[paper viper]

tru

[quaint mantle]

  @ServerStarting
  public void serverStarting(FMLServerStartingEvent event) {
    String name = getOps();

  }

[ivory sleet]

die

[quaint mantle]

This is from about 5 years ago, on some custom forge patches

The only way to get this code is steal it from a dedi, so whoever got it got what they deserved

[paper viper]

Ahahahahahahahah

MinecraftServer.D().ad().b(name);

[quaint mantle]

I don't have the source, this is from jd-gui

[cinder thistle]

lol

[young knoll]

Woo obfuscation

[paper viper]

Woo

[woven coral]

what happened with entityplayer

full line

[paper viper]

thats nms

[woven coral]

ik

im tryna use nms

but I cant

[paper viper]

You need to add it as a dependency

and run buildtools

[ivory sleet]

a list as well

wew

[sleek pond]

it needs rest, right?

[cinder thistle]

exactly

give my man some sleep

[round finch]

server goes sweepy weepy

[woven coral]

@paper viper so now I add the jar to my intellij project?

[paper viper]

nope

in your dependencies

you change spigot-api to spigot

then it will give you nms

[sacred phoenix]

What would I use to get a players speed

[sullen dome]

the effect? else, i dont think the player has a speed value

[sacred phoenix]

Not the effect but the blocks per second that they are moving

[sullen dome]

well

maybe it's possible by doing some stuff with the velocity

but velocity isnt directly it's speed

however, there are only 2 states of walking.
normal, and sprinting. faster they can't go, except they have speed effects

and sneaking ofc

[sacred phoenix]

Yeah.... I am going to be trying to measure the speed of someone moving faster then 50 blocks per second....

[abstract relic]

oh

just get the velocity

[sullen dome]

velocity isn't directly the speed if i am right

[abstract relic]

I think you can just get the length/magnitude of the velocity vector

its their "movement" vector

[sacred phoenix]

I am trying to find blocks per second as speed

[abstract relic]

well

velocity is in blocks/tick

in x y z directions

iirc

[sacred phoenix]

Ok

[abstract relic]

so if you get the length of that vector you have the total speed in blocks/tick

[sullen dome]

is looping throu Material.values; a random direction, or always the same?

i mean, is the first mat always the same?

[abstract relic]

why not loop like this to be sure

for (int i = 0; i < Material.values(); i++)

and then just go

Material material = Material.values()[i]

[sullen dome]

i want it in a random dir

[abstract relic]

so randomly pick

[sullen dome]

thats why i ask

[abstract relic]

start -> finish

finish -> start

[frail phoenix]

It's an Enum so it will always be in the same order

[paper viper]

Enums have ordinals

in fact they have a .ordinal()

method

i believe

so their indexes will be maintained

https://docs.oracle.com/javase/7/docs/api/java/lang/Enum.html#ordinal()

since java 5

[sullen dome]

what i want is assign a random material to all of them in a map.
problem is, if i do it normally, some materials would be assigned to multiple items

[paper viper]

wdym?

[sullen dome]

hard to explai nxd

[paper viper]

can you give an example

[sullen dome]

i wanna let every block drop a random item

but every item should be dropped 1 time only

[paper viper]

Yea

[sullen dome]

and not like from multiple source blocks

[paper viper]

Use a HashSet

or EnumSet

EnumSet is very fast

everytime an item drops

add it to the EnumSet

and use a while loop to randomize, although that would be extremely inefficient at the end

so here is my approach, you could copy the values array as a list of some sort

and every time you randomize, you take it out of the list

then randomize from the same list again

and so on

[sullen dome]

could i just create an arrayList, containing all materials.
and adding them in a random position?

would probably be in a random spot in the list

[paper viper]

that would be slower at first, but faster at the end

i see what you are going with that

maybe smthing like this

private static final List<Material> mats;
private static int index;

static {
  mats = EnumSet.allOf(Material.class).stream().collect(Collectors.toList());
  index = 0;
  Collections.shuffle(mats);
}

public void chooseRandom() {
  return mats.get(++index);
}

something like this

@sullen dome

[sullen dome]

yeah, i'll try that out.

ty

[paper viper]

Ok

sounds good

I am only using static because I am caching the contents

[sullen dome]

my java knowledge doesn't contain that, so i dont even ask lol

[paper viper]

you could also modify it so it removes and takes the first element

you could use a queue

[patent bloom]

hey guys, so i'm trying my hand at reading json, specifically the whitelist.json file that comes up. i'm trying to get the uuid of a passed playername. firstly, what is the proper path name to the json file? I currently have
BufferedReader br = new BufferedReader(new FileReader("\"C:\\Users\\Admin\\Desktop\\Spigot 1.16.5 Server\\whitelist.json\"")); but it doesn't look right? lol

but if anyone has any resources on hand i could use, please lmk

[paper viper]

the json file will vary

depending on the path

is this a plugin?

[patent bloom]

indeed

[paper viper]

or just standalone app

you would have to think relative paths

For example, you know how plugin jars are dropped into [SERVER FOLDER]/plugins

right

[patent bloom]

yeah

[paper viper]

now you have to think relative to that location

that means you have to go up one level

to the [SERVER FOLDER]

and then access the file that way

[patent bloom]

ah okay. i'm doing this in my test server atm, and the server folder is where the whitelist.json file is

tbh i just clicked the file explorer address bar and c/p'ed and added \whitelist.json 😓

[paper viper]

That won't work

If i was running that on my pc

it wouldn't work because the paths are different

[patent bloom]

ohhh, gotcha

[paper viper]

you know about plugin data folders right?

[patent bloom]

yup yup

[paper viper]

you could get the parent file of that and get the parent of file of that

for example

lets say your datafolder was

/plugins/MyPlugin

you could do something like

/plugins/MyPlugin and get the parent of that (which is /plugins)

[sullen dome]

would Collections.shuffle just re-order the existing contents?

[paper viper]

then get the parent of that (which is the server folder)

[paper viper]

yes

[sullen dome]

perfect

[patent bloom]

thanks! i'll have another crack at it

[paper viper]

Cool

[sullen dome]

wouldnt this to the same then?

if (matList.isEmpty())
  matList.addAll(Arrays.asList(Material.values()));
Collections.shuffle(matList);```

[paper viper]

Yes, but it is no different from my approach which uses streams

[maiden briar]

https://paste.md-5.net/ubasevated.java, why does this line give me an error? Files.copy(EindjeMinecraftPlugin.getInstance().getResourceAsStream(configFile.getName()), configFile.toPath());

[paper viper]

please use di

[sullen dome]

mine looks cleaner (to me)

[sullen dome]

what error

[maiden briar]

null

[sullen dome]

configFile is null i guess

it doesnt exists.

[maiden briar]

Nope it is not null

And it is in my resources folder

[sullen dome]

either your instance or configFile is null i guess

[chrome beacon]

Is it in the resource folder in the jar too

[chrome beacon]

Alright that looks correct

[maiden briar]

Yes as I said

[sullen dome]

weird

[maiden briar]

I always doublecheck if I don't forget something

The plugin folder will be created, but not the database.yml

[sullen dome]

so it would be something of this
getClass().getResourceAsStream(configFile.getName()), configFile.toPath())

[maiden briar]

Yes

I can try

[sullen dome]

thats what i found
