help-development

[ivory sleet]

magic values are fine if its related to state Id say (isEnabled, setEnabled), or if u do multi threaded design (where numbers sometimes are differently treated)

[lost matrix]

enums bomb the open-closed principle. Had to learn that the hard way recently.
A lot of rewriting was done

[lilac dagger]

i like to keep away from enums

[ivory sleet]

I mean sure if u facade the enum behind a pretty interface and only depend on the interface

then all good

[lilac dagger]

but where i use them it's not that important

[ivory sleet]

but most likely u dont do that

[lost matrix]

enums have their place, but in many cases you rather want a class with constants

[mortal hare]

why tf class with constants are better then enums

[ivory sleet]

yeah and now with sealed, non-sealed enums lose some of its power it had before

[mortal hare]

enums are classes and they support methods too

[grim hound]

Depends

[ivory sleet]

enums with generic type arguments is not a thing

[lost matrix]

Because enums are closed for modification and extension

[mortal hare]

and constants are closed for modification and extension

[grim hound]

Like you can use enums in a switch case

[ivory sleet]

look at minecraft for instance

[mortal hare]

and no reflections doesnt count

[ivory sleet]

EntityType is a constant declared as a registry

[lost matrix]

No? You can just extend the class which hosts those constants and add a bunch of new stuff

[grim hound]

You don't necessarily always need those

[ivory sleet]

but because its not an enum we can create our own entity types

[mortal hare]

what if those are private

[lost matrix]

Then... they are completely useless?

[ivory sleet]

extreme troll if u do that 9/10 times

[mortal hare]

also adding new functionality via inheritance for constants sounds like a code smell

[ivory sleet]

yeet what u have left of ur so called "maintainable infrastructure"

[grim hound]

How so?

[ivory sleet]

type inheritance tho

not implementation inheritance

big difference

[lost matrix]

Havent used switch cases in thousands of lines of code.
Control flow can be done much nicer and more performant differently

[smoky oak]

good argument

[ivory sleet]

because if u add a constant the class that has that switch has to recompile and everything to the right has to recompile as well

in enterprise thats horrendous if u have to do that

esp with millions of lines of code

[grim hound]

I use them decently often. They're really fast

[ivory sleet]

imagine having to recompile half of ur system to test sth just cuz of a switch

the practical time performance of switches is not bad

[mortal hare]

you're just moving recompilation performance to runtime in that case

[lost matrix]

I hate switch cases. I dont think i have a recent project with a single switch case statement

[grim hound]

Yes, it's increadibly fast

[ivory sleet]

but thats not the reason we avoid them tho lol

[grim hound]

Why would you hate them tho?

[mortal hare]

what about network protocols and parsing packet data

[lost matrix]

switch case is only fast for enums because they get converted to LUTs

[ivory sleet]

@grim hound

[grim hound]

No. It's fast for all types

[ivory sleet]

what if u change the protocol specs

[lost matrix]

Because they lead to bloated methods really fast

[ivory sleet]

then every dependency of that protocol specs has to recompile dovidas

[lost matrix]

What about it? I dont see the correlation

[grim hound]

Uh

[mortal hare]

protocol is called protocol for the reason that both ends communicate it shouldnt be drastically changed

[ornate mantle]

NullPointerException: Cannot invoke "org.bukkit.craftbukkit.v1_20_R1.CraftWorld.getHandle()" because the return value of "org.bukkit.Location.getWorld()" is null anyone know why this is happening? the world is Bukkit.getServer().getWorld("world")

[mortal hare]

you need to parse magic values, unless you want to parse bloated packets which take lots of bandwidth

[ivory sleet]

I and smile arent saying there is no usage for switches, just that its really easy to use them inappropriately

[ivory sleet]

just look at protocollib how ugly it gets

no1 wants to touch that

[lost matrix]

No you dont. The protocol is strictly defined by the serializer.

[lost matrix]

The world this location is in is not loaded at the time you called this method

[mortal hare]

it depends of what technology you use, but in the end everything is getting compressed into bitwise values and need to be deserialized, if you dont use magic values in that case you will destroy your bandwidth

[ornate mantle]

🤦‍♂️

[grim hound]

No idea what LUT is, but last time I check they're converted to an int switch case with the enum's ordinal

[ivory sleet]

noo

[lost matrix]

My guy thinks sending json with named properties via TCP is eliminating magic values...

[ivory sleet]

we can write good code and only make a little bit of the implementation cover the low end magic values part

but even then

its easy to not explicitly use magic values

[mortal hare]

imagine sending 50 byte string as a key instead of one 32bit int over the internet

[ivory sleet]

?

the amount of bytes sent is the same

[smoky oak]

isnt the minimum packet size 60 bytes or smth

[ivory sleet]

minecraft still has id based registries (for potential stuff that needs it ofc)

its just that we avoid that

u can always make some sort of handshake protocol that declares a mapping between an Id INT32 to an Id STR

that way during runtime it will understand the INT32

[lost matrix]

dovidas... you can not mix scopes like that. After leaving the application layer
with serialized data, your responsibility regarding magic values is done. Session layer, transport layer
and every layer below use strictly defined protocols. This has absolutely nothing to do with the code
we write.

[mortal hare]

it depends on the protocol, im not talking about netty, java and minecraft overall, im just saying that you cant really avoid magic values in networking, even if they would get either get encapsulated by some kind of facade, magic values would probably would be used in raw data form since those take less space and could be faster to compute on both ends. Its just that in your case you leave responsibility to map your things to serializer first before sending through the wire

[ivory sleet]

as said also, its fully possible to at app layer make the transportation just as large as is with as without

[ivory sleet]

yeah but when we retrieve the values we can be smart to not put those in the code, but to instead map them to more useful types

[smoky oak]

I mean, just send the md_5 hash

[mortal hare]

sure, but sometimes people overengineer those things quite frequently by creating unnecessary abstractions

[ivory sleet]

yeah

ofc

its important to keep a balance

[twilit basalt]

Do I have to wait one tick before map does have map view?

[smoky oak]

if you have to wait its 2 ticks lemme tell u that

[twilit basalt]

2 ticks?

[smoky oak]

everything i experienced delays with so far had a 2 tick delay

[grim hound]

Is there a way to have the same plugin work both on Spigot and BungeeCord? And by that I mean the loading class

[grim hound]

No

[ivory sleet]

yes

plugin.yml and bungee.yml

[smoky oak]

afaik yea, if you just check what ur running on and change code appropriately

[ivory sleet]

but they cant be the same class

[grim hound]

Well also depends when you're checking

[lost matrix]

99% of the time you need to wait 1 tick *if anything.
2 ticks sounds arbitrary

[ivory sleet]

since ud get a NCDFE error otherwise shadow

[smoky oak]

smile

inventory updates on client

item switch read by server

[grim hound]

But isn't plugin.yml also read by bungeecord?

[ivory sleet]

bungee.yml takes priority iirc

[grim hound]

I see, thanks

[lost matrix]

Those require 0 ticks delay and can evaluated in the same tick

[smoky oak]

oh sure it fires the event that tik

but the actual attributes of the player n stuff is only updated two ticks later

[lost matrix]

I dont believe you. Let me check that out.

[smoky oak]

lemme just ping u some code

@lost matrix

private BukkitRunnable speedUpdater =
            new BukkitRunnable() {
        @Override public void run() {
            AttributeInstance speedAttribute = player.getAttribute(Attribute.GENERIC_ATTACK_SPEED);
            //return if illegal speed set
            if(player == null || !player.isOnline()) return;
            //calc & apply
            double currentSpeed = speedAttribute.getValue();
            
        }};
``` run this at 1 and 2 ticks delay from the event, print out speed when switching from nothing to a weapon

[twilit basalt]

Then why it has no map view

[grim hound]

Back to the topic, switch cases are really useful. Like if you have a ChannelReader, the fastest way to determine a packet is by using a class' SimpleName in a switch case (like for example instead of an instanceof)

[grim hound]

Sometimes it doesn't have a map view I think

[ivory sleet]

have u benchmarked?

[grim hound]

Might differ depending on the version

Yes

0.013 ms - the switch case with like 10 branches
3.3 ms - same thing but using instanceof

[quaint mantle]

Can you use protobuf over netty?

[ivory sleet]

thats instanceof

I think an IntToObjMap from fastutil or trove would do really good as well

or well if its alr a packet obj, then IdentityHashMap<Class<?>,V> perhaps

[grim hound]

But then what other ways do you have? I tested many, Class#getSimpleName in a switch case was the fastest

[grim hound]

Hmmm

I tested literal class comparison and it was also slower than the switch case

Like getClass() == PacketPlayInPosition.class

[ivory sleet]

show me the benchmark

[grim hound]

Does Identity HashMap not use the Object#equals? Ooo maybe like Map<String, Method> might be faster

[ivory sleet]

no it doesnt

[grim hound]

I currently can't

[ivory sleet]

it uses System::identityHashCode

[grim hound]

You can test it yourself

[ivory sleet]

nah

[grim hound]

That's for saving the object.

[ivory sleet]

u wanted to prove the switch is better for w/e reason

[lost matrix]

You are right, attributes get applied 2 ticks after the switch event.
This might be literally the only occasion where a 2 tick delay makes sense.

[ivory sleet]

???

[smoky oak]

oh its not the only one

[grim hound]

Normal maps use Object#hashCode but also Object#equals in case of a hash collision

[smoky oak]

the same nonsense is with player blocking with shields

[twilit basalt]

When

[smoky oak]

remove shield, wait 2 ticks, give shield back

[ivory sleet]

and IdentityHashMap uses System::identityHashCode

[smoky oak]

or they keep blocking even if you disabled their damn shield

[grim hound]

Have you look at HashMap's source code?

[ivory sleet]

im not talking about HashMap

[lost matrix]

Whats this about?

[grim hound]

I get that. But what does it do in case of a hash collision?

[smoky oak]

which of us lol

[grim hound]

Can you show your code? Cuz I ain't sure

[slender elbow]

well it's based on identity so I would assume it uses referential equality

[twilit basalt]

Umm I am not on pc right now, but I just get map view from mapmeta

[slender elbow]

can't say I've looked at the source, but the entire premise of IHM is that it's identity based

[twilit basalt]

And I get mapmeta right after creating itemstack, getting meta and casting it

[grim hound]

Then it wouldn't really be faster than a switch case

[lost matrix]

You mean a switch case on a String?
I wouldnt use that even if it was slightly faster than a switch case on a type.
Which is probably faster anyways

[ivory sleet]

collisions should be rare but then yeah what emily said

[grim hound]

Switch case on a type? What type?

[smoky oak]

Hm i just noticed something. a player's yaw and pitch 0 equal a player looking towards +z, shouldnt it be +x?

[grim hound]

Yaw is bugged

[slender elbow]

Minecrafts axis are completely fucked up

[lost matrix]

The type of the class you are calling getSimpleName on

[smoky oak]

ah of course lol

welp this makes the geometry 10 times harder

[slender elbow]

one is mirrored and the whole thing is 90 degrees phased off

[grim hound]

I once had 180 and my friend had -180. We were both looking in the same direction

[lost matrix]

And y points up for some reason

[grim hound]

You can't use class types in a switch case

[slender elbow]

oh yeah and that

[smoky oak]

bleh

should i use +x as my 'normal' or +z as my 'normal' orientation

either's bad here

[onyx fjord]

if you dont want fucked up direction you gotta run a modulo

so its never on minus

[onyx fjord]

soon tm

[grim hound]

A modulo on a negative number will not help

[smoky oak]

im aware of that, but that would probably translate into negative rotation values. not the question anyway

[ivory sleet]

you can but not for all types

sealed allows for it

[worldly ingot]

o.O You can switch sealed types?

[slender elbow]

sealedn

[grim hound]

Oo you can use class types in newer java versions? Quiet nice

[ivory sleet]

I think yeah? if that still isnt preview lol

[worldly ingot]

I know there's pattern matching (soon™️)

[lost matrix]

Hm, right. Classes are runtime dependent. Cant really use them in a switch.

[grim hound]

Yeah, I tried that

[lost matrix]

Well. Map<Class, > it is then

[grim hound]

Nope. It's still slower than a switch case

[ivory sleet]

oh its j21 nvm basically no1 uses it

[onyx fjord]

in preview

[slender elbow]

what are you even doing that demands the most of every single CPU cycle anyway

[onyx fjord]

in 17 at least

[ivory sleet]

yep

[worldly ingot]

Everything requires as little clock cycles as possible >:((

[ivory sleet]

yea here

[lost matrix]

Ill benchmark this real quick

[ivory sleet]

bru

[slender elbow]

gj

[ivory sleet]

:]

[grim hound]

Maybe Map<Integer, ?> With a Hash Code would be faster

[grim hound]

Go ahead

[smoky oak]

how the f

[ivory sleet]

but that fucks up collisions

assuming u get ur integers from some object

[slender elbow]

congratulations, you just invented the hash map

but worse

[grim hound]

Yoo dassick

[ivory sleet]

fastutil has IntToObjMap<V> which u may be interested of instead shadow

yea :)

[slender elbow]

also I'm pretty sure a Class's hash code is cached? if it's the identity HC then it's definitely cached

[grim hound]

Nononono. It would still be better than using Class as the Key

[ivory sleet]

how

[grim hound]

I've never used FastUtils. Now I'm interested

[ivory sleet]

yeah its sick

[lilac dagger]

i wish fast utils was present with the api

[slender elbow]

no lol

[grim hound]

Cuz it uses Object#equals on a class. And Integer#equals is faster

[grim hound]

Yes

[slender elbow]

no

[lilac dagger]

both are the same

[grim hound]

It is. Spigot uses FastUtils

[lilac dagger]

it's not in the spigot-api

[ivory sleet]

did u just forget about IdentityHashMap<Class,V> ? :c

[lilac dagger]

i use identity in some places

[grim hound]

Nope. Object#equals compares variables and Integer#equals just the stored value

[lilac dagger]

where i know the keys are gonna be the same all through the store

[lilac dagger]

do you mean int?

[grim hound]

I never used IdentityHashMap so I can't really tell

[remote swallow]

int doesnt have equals

Integer does

[grim hound]

It's casted into an Integer when stored

Or converted I should say

[lilac dagger]

autoboxed

[grim hound]

Ye

[ivory sleet]

shadow

and best part

Class#equals is just Object#equals

:)

(j17 btw)

[grim hound]

What about it?

[grim hound]

I know

[ivory sleet]

this

[grim hound]

And == compares all fields

[ivory sleet]

no lmao

thats wrong

[grim hound]

Yes

[slender elbow]

that's just plain wrong

[ivory sleet]

it compares memory addresses (if u dumb it down)

[lilac dagger]

there is an id that gets compared

the memory address yeah

[slender elbow]

if you're gonna speak so confidently about something at least make sure it's correct beforehand

[grim hound]

That's what I read in many sources

[ivory sleet]

what are those sources lol

[grim hound]

Not always

[slender elbow]

yes always

it's called referential equality

[ivory sleet]

um missclick

[slender elbow]

and back to this, it's the same (but worse cuz no collision handling), either you call hashCode on the class and you can't deal with collisions without extra handling, or the map does and also deals with collisions appropriately, it's literally the same for this use case

[ivory sleet]

anyway shadow it feels like u r a bit under the Dunning–Kruger syndrome not to be mean but just trying to imply a little bit what emily said before

[lilac dagger]

it might be faster i dunno

[grim hound]

A wat now

[ivory sleet]

it isnt

instanceof and then a == comparison

[lilac dagger]

oh wait

[ivory sleet]

def slower than just ==

[lilac dagger]

this equals is implemented for hashmap

nevermind

[grim hound]

Then how does IdentityHashMap deal with hash collision? By creating a tree?

[slender elbow]

a tree or a linked list

[grim hound]

It is

[slender elbow]

that is also the case for HashMap

that is the case for any collision handling ever

[grim hound]

Then how would it be faster?

[slender elbow]

how would your solution be?

"yeah no collision handling"

I would argue that losing data is not worth it lmao

[grim hound]

hashCode is usually overwritten to make it more unique. Replacing that with the identity hash codes makes little to no sense

[slender elbow]

but they can still collide

any int is as equally rare as any other int

[lilac dagger]

you're confusing hashmaps with identity hashmaps tho

[grim hound]

Yeah I agree, I just don't get what benefit does using the IdentityHashMap provide to it's brothers?

[ivory sleet]

first and foremost, collisions rarely happen in IHM like the chance of that is low, esp if u just have like 300 packet types

[smoky oak]

testRunnable.runTaskLater(Echo.getInstance(),10);
testRunnable.cancel();
testRunnable.runTaskLater(Echo.getInstance(), 10);

java.lang.IllegalStateException: Already scheduled as 6
fuck do u mean ur scheduled

u dont exist

[lilac dagger]

ah yes

[grim hound]

That is true. They're not impossible tho

[ivory sleet]

yes but this is why we run our benchmarks many many times

[lilac dagger]

@smoky oak tasks take longer to be removed

[ivory sleet]

to avoid randomties that may affect it

[grim hound]

It's a bukkit runnable. Look at the src

[smoky oak]

sooo

make a new one

[grim hound]

The BukkitRunnable obj can be scheduled only once

[grim hound]

Use your own Runnable impl class

[ivory sleet]

anyway I just read through identity hash map

[smoky oak]

nah, I'll just be like 'reset_runnable(){runnable = new BukkitRunnable...'

[ivory sleet]

it seems to be making space for a collision every other element (dk if i read it right tho)

[grim hound]

Dooont doo that

[smoky oak]

got a better idea?

[grim hound]

Yes. All HashMaps do that

[grim hound]

Ye

[grim hound]

.

[smoky oak]

er

hows that going to help

[ivory sleet]

no

not in the same way hashmap does it

hashmap has a given internal tree node structure

[smoky oak]

actually i can just reinstantiate the wrapper

[ivory sleet]

identity hash map just uses a circular traversal

[grim hound]

Well the BukkitRunnable disallows multiple scheduling. You own class doesn't.

[grim hound]

Eeeee

[ivory sleet]

but thats actually faster

assuming the amount of collisions are low

which they definitely will be

most likely ranging from 0 to 2

altho 0 is gonna be it 99% of the times

[grim hound]

So like a Node-based system?

[ivory sleet]

not like a node based system

[floral drum]

weeeeeee

[grim hound]

Got it

[smoky oak]

there problem solved. death = leave, respawn = join

[ivory sleet]

https://github.com/openjdk/jdk21/blob/master/src/java.base/share/classes/java/util/IdentityHashMap.java here

u can read it

[lost matrix]

First benchmark is a bit inconclusive

Benchmark                               Mode  Cnt    Score    Error  Units

SwitchScale.hashMapAccessAverage        avgt    5    0,643 ±  1,881  ns/op
SwitchScale.hashMapAccessWorstCase      avgt    5    4,873 ±  0,035  ns/op

SwitchScale.identityMapAccessAverage    avgt    5    0,586 ±  2,108  ns/op
SwitchScale.identityMapAccessWorstCase  avgt    5    3,638 ±  0,263  ns/op

SwitchScale.switchCaseAccessAverage     avgt    5    2,168 ±  1,424  ns/op
SwitchScale.switchCaseAccessWorstCase   avgt    5    4,936 ±  0,024  ns/op

The error is still a bit too high. Ill try throughput.

[ivory sleet]

yea

[grim hound]

Anyway, I still don't think that using a Map is faster. Map<UUID, ?> took for me 0.015 ms. For a class it would be longer. If I don't have like 10 000 elements, using a switch case should be still faster

[ivory sleet]

if u have like 2 cases then just use if else lmao

[lost matrix]

0.015ms sounds like a LOT for either method

[grim hound]

Like what's the point of a Map with 15 entries when a switch case is a confirmed faster one

[grim hound]

Wat.

[ivory sleet]

because the amount of entries can grow, and everything isnt about speed

we care about design, maintainability and flexibility also

[grim hound]

No. I have ~13 cases

[grim hound]

It's really easy to add a switch case branch

[ivory sleet]

its not about it being easy

[grim hound]

With just the packet's name

[ivory sleet]

its just as easy to add it with a map bro

but with switches I have to add a case everywhere if I add a new constant

[warm mica]

Overoptimization contributes to poor code design and isn't always a good idea

[ivory sleet]

with switches I have to compile everything to the right

u havent ever been in an enterprise dev org where it acc takes time to compile a large code base, have u?

[grim hound]

I feel like I'm talking with chat gpt right now

[grim hound]

Wat

[remote swallow]

whats used to benchmark this

[grim hound]

Yeah no, but why would that matter? For my case it would take much more code for it to be in a Map rather than in a switch case

[ivory sleet]

it matters because the industry care about it

for ur duct taped little project u can use whatever u want w/o any greater severe impacts

[grim hound]

Hmmm

[ivory sleet]

u could use static and go around and say its faster

[onyx fjord]

how do you benchmark

[ivory sleet]

because u have dynamic dispatch based virtual tables for ur instance methods

[onyx fjord]

can you send your benchmark?

[ivory sleet]

with invokestatic

[grim hound]

Cuz it is xD

[ivory sleet]

yeah

go do that

maybe write in assembly as well

that way no gc or anything will stop u

[grim hound]

I'm on my phone and it's night time, I'll send it tomorrow

[onyx fjord]

okay but you are using what for benchmarks

[grim hound]

Yooo, that's a great optimization

[grim hound]

?

[onyx fjord]

like what framework/tool

[ivory sleet]

yeah go do that, lets just say I wouldnt ever touch a project uve been on but thats just me

[remote swallow]

how are you benchmarking

[grim hound]

A Runnable

[remote swallow]

that isnt benchmarking

[grim hound]

My own method

[onyx fjord]

i have a suspicion that you are using System.currentTimeMilis

[grim hound]

How would I get 0.013 ms then?

[onyx fjord]

wdym

[grim hound]

System.nanoTime :D

[onyx fjord]

that method itself is slow

a lot slower than currenttimemilis

and your benchmark isnt accurate

[ivory sleet]

both are utterly and completely wrong to use and INVALID if u are benchmarking

[grim hound]

Ms is milliseconds. And it's a whole number.

[slender elbow]

yeah that isn't how you benchmark

[ivory sleet]

ur benchmarks dont prove anything because u didnt do any

[onyx fjord]

you should only ever use either when returning time to the user

i do with /reload command for example

[grim hound]

Eee

[onyx fjord]

because accuracy doesnt matter there

but for this case it matters

[slender elbow]

the jvm is a really really complex machine and using a simple loop with System.nanotime/currentTimeMillis is basically garbage measurements

[near mason]

What is benchmarking?

😐

[remote swallow]

kacper what tool you use for benchmarking

[onyx fjord]

running something and seeing how fast it completes

[onyx fjord]

jmh

[near mason]

Oh ok

[onyx fjord]

or how much load it causes

but the point is checking the speed

[grim hound]

I mean there is a really small difference of like 0.001 ms betweeen each try but that's it

[near mason]

Wait really

[ivory sleet]

we test how fast functions are by running them in a specific environment where its as error prone less as possible

[near mason]

I always used them to benchmark

[onyx fjord]

still your benchmark is worthless

[slender elbow]

workless

[grim hound]

Not really

[slender elbow]

yes really

seriously, read up on hotspot

[near mason]

How do i do it then?

[grim hound]

Now that feels personal

[onyx fjord]

its ok if you accept few miliseconds of error

but when doing this type of benchmark

things take nano/microseconds

[onyx fjord]

how so?

[ivory sleet]

smile

give us some actual benchmarks

[grim hound]

Not "a few milliseconds" but rather "a few hundred nano seconds"

[onyx fjord]

still

[slender elbow]

I am once again asking for your financial support

[onyx fjord]

• i dobut

[lilac dagger]

what was the annotation benchmark thingy?

jhm?

[slender elbow]

yes

[onyx fjord]

getting nanoseconds is expensive

[grim hound]

So insensitive and direct

[lilac dagger]

try with that 😄

[onyx fjord]

wrong but ok

[grim hound]

Wat

[onyx fjord]

read my message again

the original one

nobody is attacking your personally

[lilac dagger]

i feel like we've put shadow on defensive mode now

[opal carbon]

if a benchmark is entirely invalid and shows nothing helpful its worthless

[grim hound]

Ya, I wasn't serious about that

[onyx fjord]

ofc

[ivory sleet]

very much so

[grim hound]

Man, I should've maxed out my defense skills

[lilac dagger]

haha

[onyx fjord]

whats the code behind

[lost matrix]

?paste

[undone axle]

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

[ivory sleet]

how many entries

[slender elbow]

3

at least

[lost matrix]

18

[slender elbow]

old enough

[grim hound]

Wat

Thank god you're not a pedophille

[onyx fjord]

thrpt score higher = better?

[slender elbow]

higher

throughput

[ivory sleet]

oh

[near mason]

So ı use jmh to benchmark

[ivory sleet]

nvm

[onyx fjord]

yea

[lost matrix]

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

[onyx fjord]

we all love the blackhole

[grim hound]

Uh

[lost matrix]

So either map had a significantly higher throughput

[onyx fjord]

FUCK JIT

[slender elbow]

so good

[near mason]

And system.currentTimeMillis is not accurate

When benchmarking

[grim hound]

I don't know what the values mean

[grim hound]

System.nanoTime

[lost matrix]

The values mean that maps are faster

*But let me do some more tests

[grim hound]

Naah, tell me what they mean, exactly

[slender elbow]

do 1, 10, 100, 1000, 10000, 100000 entries

[near mason]

I use system. Nanotime?

[onyx fjord]

whats IdentityHashMap for

[lost matrix]

Mode: thrpt => Throughput
Score: N +/- M ops/us => Operations per micro second

[grim hound]

What did the man do (jk)

[lost matrix]

I would, but switch cases cant dynamically scale

[gilded granite]

any1 has a packet lisntner code?

[onyx fjord]

optimized without consent

[slender elbow]

codegen

[grim hound]

I do

[gilded granite]

Can you please share it with me

[onyx fjord]

what packet listener

like netty?

[grim hound]

Decompile AlixSystem on spigot, as I can't send it right now

[slender elbow]

-Xint :trollface:

[gilded granite]

like it logs every packet send or receive in the server logs

[lilac dagger]

i don't think it's a fair comparision to be honest, map takes space while switches don't, i still find them best in some situations

[ivory sleet]

smile has

[lost matrix]

10GB log file after a day. lol.

[grim hound]

Go into shadow.utils.objects.filter.packet

[ivory sleet]

smile has accly good packet code last time I read that lol

[slender elbow]

netty LoggingHandler

[gilded granite]

I dont have the depedancy

I use mojangs mapping

[onyx fjord]

why is it like that @grim hound

[lost matrix]

Cant open a proj right now bc of benchmark. Otherwise i would lend you mine.
If you wait 5m ill send it

[grim hound]

And in the PacketBlocker class you will find the defaultInject method

[remote swallow]

jarinjar

[grim hound]

You mean that you don't use spigot?

[grim hound]

Ya, compression is great, use it myself

[onyx fjord]

???

[slender elbow]

jar in jar has nothing to do with compression

[grim hound]

?

[slender elbow]

i don't have time for this

[lost matrix]

Jar is already a compressed format. I dont think you can compress it any furthert.

[gilded granite]

Yes i use it but with mojangs maping

[remote swallow]

its a plugin on spigot he wants you to decompile

[slender elbow]

zipping a zip won't do anything useful yeah

[grim hound]

My plugin weighted 320 KB and after I made it into a jarinjar and added an jarinjar loader classes it weightes 280 KB so you know

[kind hatch]

Zip bomb!

[grim hound]

So like ServerboundClientCommandPacket stuff?

[gilded granite]

yes

[lost matrix]

3m ill send you something for packet listening

[grim hound]

Damn

[gilded granite]

ok thx

And btw is there anyways to modify the server code?

[grim hound]

But you do have access to the spigot api?

[grim hound]

ByteBuddy

[lost matrix]

You can fork spigot if you want to write your own server version

[gilded granite]

Yes i have access

[onyx fjord]

what do you wanna modify

[gilded granite]

buch of things

[onyx fjord]

then fork

[grim hound]

CraftPlayer#getHandle and then like the player connection network manager and you get the Channel object.

[onyx fjord]

tbh i'd recommend just using a packet library

no need for nms

easier multi version support

[grim hound]

And just invoke Channel#addBefore("packet_handler", "whatever", new MyChannelDuplexClass());

[gilded granite]

ok

[remote swallow]

seems like bad design icl

having to do that for every single player

[grim hound]

You can do it async

[onyx fjord]

thats how its done usually

[grim hound]

And it's fast

[remote swallow]

i dont believe you when you say its fast

[ivory sleet]

async doesnt mean faster tho necessarily

[onyx fjord]

async generally means more overhead ^

[grim hound]

I said and

[slender elbow]

don't even think about doing blocking operations on the nettu threads

[lost matrix]

Benchmark                               Mode  Cnt    Score   Error  Units
SwitchScale.hashMapAccessAverage        avgt    6    4,271 ± 0,113  ns/op

SwitchScale.switchCaseAccessWorstCase   avgt    6    4,979 ± 0,082  ns/op

Honestly this concludes it for me. (At least for 18 entries)
Map lookup is faster than a switch statement.

[grim hound]

Bruh chill y'all

[onyx fjord]

?

[slender elbow]

i mean if you want to drastically increase the latency of a quarter of your players then go ahead lmao

[grim hound]

I just said that it's fast and it can also be done async

[slender elbow]

or, wlel, all

[grim hound]

So no need to synchronize

[grim hound]

Y'all need to listen better

[gilded granite]

i cant find the spigot source code breh

[grim hound]

Or at least read

[gilded granite]

?source code

[remote swallow]

?stash

[undone axle]

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

[onyx fjord]

i feel like you are having trouble understanding some java concepts

[remote swallow]

what source code are you looking for

[gilded granite]

spigot server 1.20

[remote swallow]

what part of it

[onyx fjord]

probably all of it

[gilded granite]

all

[remote swallow]

if you want the patched mc server, run buildtools and open spigot as an intellij project

[grim hound]

Are you doing this on purpose? Like not reading and stuff?

Anyway gtg to sleep

We shall argue another day fellows!

Goodnight

ehm... non existent benchmarks

[gilded granite]

Thx

[onyx fjord]

conclure you are wrong

they exist

[grim hound]

Uh. You just use another tool for that

[ivory sleet]

oh yes my bad

[onyx fjord]

maybe theyre invalid

accuracy-wise

but they exist

[grim hound]

That's more like it

Anyway goodnight

[slender elbow]

o/

[lost matrix]

hashmap, yay

Wait... i just realised that my code actually uses a switch statement o.O

Disgraceful

And that for a binary case

That needs some fixing

[ivory sleet]

u became the very thing u swore to destroy

lol

[lost matrix]

Compiler will optimize this to if-else probably

maybe

[quaint mantle]

i kinda hate what you did here

[lost matrix]

same

[quaint mantle]

you could put more FP over here

[lost matrix]

file pointer?

[tardy mist]

I think he means functional programming

[next zinc]

How difficult would it be to code a duels like plugin?

Never coded something on that scale before and want to know what I'm dealing with before hand

[lost matrix]

You mean simply letting people only attack each other if they are in a duel?

[gilded granite]

how i can remove the cooldown of damaging entities

[lost matrix]

Set the no damage ticks to 0

[gilded granite]

like for example when shooting fast at zombie with a bow it reflec the arrow and doesnt damage him

how do i remove that?

[gilded granite]

how?

[lost matrix]

Set the no damage ticks to 0

[gilded granite]

where?

[lost matrix]

when an entitiy is damaged, set its no damage ticks to 0
You might need to delay that by one tick

[gilded granite]

onEntityDama

ok

cant find it java @EventHandler public void noDmgCoolDown(EntityDamageEvent event) { Entity entity = event.getEntity(); new BukkitRunnable() { @Override public void run() { entity.; } }.runTaskLater(Plugin.getInstance(), 1L); }

[lost matrix]

setNoDamageTicks

[gilded granite]

it doesnt exist

Cannot resolve method 'setNoDamageTicks' in 'Entity'

[lost matrix]

Only exists in LivingEntity ofc

[remote swallow]

word nerds what could i call a config option that would happen on every login

cant be join

has to be join.something

[lost matrix]

join.join

join.login_action

[river oracle]

join.action

or join.event

[remote swallow]

technically its a message config not a config option but same thingy

[river oracle]

Oh

[river oracle]

join.on-join

[remote swallow]

works for me

[lilac dagger]

Session.join

How to get after player.setResourcePack did player install resource pack or not?

[opal carbon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerResourcePackStatusEvent.html

[kindred sentinel]

Oh, thx!

[opal carbon]

pls read javadocs it says right on there

"Players can disable server resources on their client, in which case this method will have no affect on them. Use the PlayerResourcePackStatusEvent to figure out whether or not the player loaded the pack!"

[quaint mantle]

isnt the arena generation the hardest?

it seems intimidating to do

[unborn hawk]

hey guys, new here so sorry if this is the wrong place to ask this question.
im a server admin for a Paper server (running Paper version 1.20.1-112 specifically) and im trying to work out how to alter the length of the day / night cycle, ive searched everywhere and cant find any settings in any .YML files (Bukkit, Spigot or Paper) and i cant find any compatible Spigot plugins for 1.20.1
we're just trying to make days last twice as long, i didnt think that would be very hard, but turns out it is lol
could anyone point me in the right direction as to how i could achieve this? Spigot plugins have been my go to, to alter the server so far, they seem to be the way to go, i just cant figure it out

[quaint mantle]

key word server admin

also

paper?

?whereami

[undone axle]

https://cdn.discordapp.com/attachments/864180468680360027/944415049462714469/whereami.mp4

[unborn hawk]

well yeah like i said, i dont really use Paper much, i mainly use Spigot plugins, hence why i thought of here 😛

[lost matrix]

isnt threre a pluhgin

for this

[unborn hawk]

yeah im sure there is, i just cant seem to find it 😦

seems like a fairly basic thing to have a plugin for

[quaint mantle]

`https://www.spigotmc.org/resources/custom-day-length.101165/

[unborn hawk]

yeah i tried that one, its only 1.18 compatible, we're running 1.20.1

[quaint mantle]

I dont see anyhhing in the code

thast wouldnt work on 1.20.1

[unborn hawk]

server just crashed when i restarted after chucking it into the plugins folder

maybe i fucked it up, ill try again

[quaint mantle]

error?

[unborn hawk]

yes your right, it does still work with 1.20.1, thank you mate, dunno how i installed it first time but i obviously fucked it up (probably but it in a folder or something i dunno)

sorry for the stupidity!

[true perch]

What's the most efficient way to implement a boss bar at the top of a player's screen?

Does it involve me spawning a boss (No ai, invisible, custom name) below bedrock at a player? Or are there new ways of achieving this?

[worldly ingot]

You can create a virtual boss bar with Bukkit#createBossBar()

Gives you back a BossBar instance on which you can invoke #addPlayer()

[true perch]

That's exactly what I needed, thank you sir.

[true perch]

Is it possible to tell what size a player's client is through the Spigot API?

If not, is there a way to tell whether or not they're using full screen? (less preferred)

[lost matrix]

Nope. For all you know he could play a headless client that has no graphical window at all

[true perch]

Understood, thank you!

[jaunty crag]

can someone help me understand how big servers like hypixel have several little servers used to host mini games and stuff that all still communicate with eachother sharing things like party information and such? i’ve only ever seen one jar file host one server at a time so i am curious

[worldly ingot]

Technologies like Docker and Kubernetes can be used to spin up servers as necessary, but there's a whole tech stack behind that

As for communicating things between servers, just a simple Redis and MySQL database shared between servers will suffice

[quaint mantle]

Does anyone have proguard rules for plugins? I have read that proguard obuscation is allowed as long as main class name isn't obuscated

Link (https://www.spigotmc.org/threads/approved-obfuscators.420746/)

[jaunty crag]

databases… why did i completely forget about this

wouldn’t they have to be realtime though? some servers like mcc have queue systems

[worldly ingot]

Redis is an in-memory database so it's very quick

[river oracle]

personally wouldn't even bother with obfuscation

idk what @tender shard but he uses obfuscators so he might have a set of rules that can be used or something

[vagrant stratus]

[kind hatch]

If you only need a single color, then just set the foreground color. If you need multiple colors, you can either convert everything to html and use the inline styling, or use a customized JTextPane and insert strings on the document with whatever styling you need.

[round finch]

how insert on document?

[sage patio]

how can i check if player enters a number like /test 56, he has test.56 permission? for example i set test.69 for a player, he can do at max /test 69, /test 1 - 69 are allowed but /test 70 not

the only way is permission check from 1 to ... ?

[novel mauve]

yo how do you give a pre existing mob a boss bar?

like just a normal mob like elder guardian for EG

[near mason]

make a Hashmap

[sage patio]

then what

[near mason]

add players uuid and his max test int

[sage patio]

doing a for loop when he enters the server or ...? for checking his permission

what if he gets a permission while his already in the server

[near mason]

when you give him the permission

you will add his uuid to hashmap

map.put(player.getUniqueId(), maxTest);

then you will serialize it to a file onDisable

deserialize it back onEnable

[sage patio]

i've to use luckperms api or there is something for it in spigot (for the permission)

[novel mauve]

please

[near mason]

https://www.spigotmc.org/threads/get-player-permissions.530487/

check the danirod12's answer

idk if there is a way to add bossbar directly to an entity

but you can create a bossbar

than update it whenever he heals and get damages

[novel mauve]

so i just use damage and heal events?

[near mason]

listen to EntityRegainHealthEvent and EntityDamageEvent

and update the bossbar in them

[novel mauve]

thanks

also dyk if subtract is broken

like location.subtract

[tall dragon]

why would that be broken

[near mason]

wdym its broken?

[novel mauve]

for some reason it just, doesnt subtract

[near mason]

heh

[novel mauve]

i was tryna get 4 adjacent blocks to a block

the add methods worked but the subtract method just got the central block

had to use blockface

[tall dragon]

yea u add first and then subtract back to the central block

probably

show code

[novel mauve]

nono i used this too

[tall dragon]

that does not work?

[novel mauve]

nope, would get the first and 3rd block

wouldnt get the 2nd and 4th

(the minus ones)

[tall dragon]

seems odd

imo its better to use the method intended for it anyway

[novel mauve]

yeah block face works like a charm

also lets say theres a collection of mobs i wanna keep track of (say like mobs i want a bossbar of), is the wisest decision to just keep an array of them in my main class?

[tall dragon]

honestly depends on how big your plugin is. but i would not

[near mason]

u can also use Block.getRelative(x, y, z)

[tall dragon]

i would either keep it in the class where the listeners are or i would create a seperate class to keep track of the mobs

probably a seperate class since ur going to need to access that list not just from the listeners probably

[novel mauve]

yeah okay

actually on 2nd thought i only need it in my listeners class

cuz its not a crazy big plugin or nothing im just creating like a custom elder guardian boss

[novel mauve]

but my listeners are in my main class 😭

[tall dragon]

well hecking move them!

[novel mauve]

why is it a bad practice tho

[tall dragon]

its just unreadable

when you have specific classes for listeners its so much easier to find stuff

like a PlayerListener class can handle player related events

for plugins with 1 or 2 listeners its fine i guess

but beyond that it quickly becomes annoying

[novel mauve]

ahh okay i see

[abstract spindle]

Is it possible to change the path from witch an Inventory gets it looks ?
I know you can change it for all if you have a recourcepack and edit the files in asset\minecraft\textures\gui\container
But I want to add a container and want to open that if the Invenory the player opens has a custom Name

[near mason]

is there a way to get class from generic type?

[smoky anchor]

no

[novel mauve]

how do i get GENERIC_MAX_HEALTH as an int instead of attributeinstance

can i just cast to int?

[lilac dagger]

of course

it would be better to round it first

[novel mauve]

aight thanks

[novel mauve]

i cant

[smoky anchor]

there is .getValue I think and it will return a double

[novel mauve]

thanks

[upper hazel]

give someone a normal tutorial on creating your worldguard api flags

the documentation is kind of confusing. Where to register a listener

i dont undestand

[quaint mantle]

maybe you dont

not every api needs a listener

maybe it is done by first registering the type and then checking it on block

[upper hazel]

I need a flag that allows only certain blocks to be broken and, logically, there should be a listener, or I don’t know

[lilac dagger]

you need to cast the value

[robust helm]

getBaseValue

[abstract spindle]

First I recommend Creating a Class that represents your Flag for example:

public class YourFlag {

    BooleanFlag booleanFlag;

    @Getter
    private BooleanFlag flag;

    public void register() {
        FlagRegistry flagRegistry = WorldGuard.getInstance().getFlagRegistry();
        try {
            flag = new BooleanFlag("Your_Flag");
            flagRegistry.register(flag);
            this.booleanFlag = flag;
        } catch (FlagConflictException e) {
            Flag<?> existing = flagRegistry.get("Your_Flag");
            if (existing instanceof BooleanFlag) {
                booleanFlag = (BooleanFlag) existing;
            } else {
                Bukkit.getLogger().log(Level.SEVERE, "Something already created a Your_Flag Flag");
            }
        }
    }

    public static ProtectedRegion apply(ProtectedRegion protectedRegion, Boolean value) {
        protectedRegion.setFlag(new BooleanFlag("Your_Flag"), value);
        return protectedRegion;
    }
}

Then you create a Methode to check if a Player is in A Region with this Flag:

public boolean isPlayerInRegionYourFlag(Player player) {
        var returnValue = false;

        RegionContainer container = WorldGuard.getInstance().getPlatform().getRegionContainer();
        RegionQuery query = container.createQuery();
        ApplicableRegionSet set = query.getApplicableRegions(BukkitAdapter.adapt(player.getLocation()));
        LocalPlayer localPlayer = WorldGuardPlugin.inst().wrapPlayer(player);
        for (ProtectedRegion protectedRegion : set) {
            if (Objects.equals(protectedRegion.getFlag(YourFlag.getFlag()), Boolean.TRUE)) {
                returnValue = true;
            }
        }

        return returnValue;
    }

Then you can use that to listen to your envents and handel the response

[quaint mantle]

see? like i said

[abstract spindle]

Don`t forget to Register your Flag

[upper hazel]

were i shold register 2 metod for loop

check

[novel mauve]

yo if i spawn a mob how do i give them a purple coloured name with "BOSS"

like a name tag has been used on them

[upper hazel]

displayName

end chat.color enum or color coding

[novel mauve]

displayname seems to be for players

[upper hazel]

for mob exists too

[smoky anchor]

entity.setCustomName(ChatColor.LIGHT_PURPLE + "BOSS");

[novel mauve]

thanks

[novel mauve]

yup u were right

BossBar bossBar = Bukkit.getBossBar(new NamespacedKey(this, Integer.toString(EGBoss.getEntityId())));
            bossBar.setProgress(EGBoss.getHealth()/EGBoss.getAttribute(Attribute.GENERIC_MAX_HEALTH).getValue()); 

if(bossBar.getProgress() == 0){ // Remove bossbar from all players screen if bossbar health reaches 0 (meaning custom elderguardian boss has died)
                bossBar.removeAll();

for some reason when i kill the egboss entity the bossbar isnt at 0

[upper hazel]

ooh buddy boss bar is a separate unpleasant (for me for sure) topic

[novel mauve]

this is how much health it has on death

[upper hazel]

Well, I think you should synchronize the HP of the mob and bar

[novel mauve]

is that not what bossBar.setProgress(EGBoss.getHealth()/EGBoss.getAttribute(Attribute.GENERIC_MAX_HEALTH).getValue()); is doing?

[abstract spindle]

The EnderDragon shows only 0 because it is not instantly removed - But your remove it instantly

I would recommend using a timer to remove it when it reaches 0

[upper hazel]

@abstract spindle But how to register the flag event itself and does the wolrdguard api have its own events?

for example, I need a block breaking event

for check wat the material

in flag

[tender shard]

yeah but only for allatori

[abstract spindle]

register in your Plugin the Blockbreaking Event and check if the player is in the region with the flag and then do your check

[upper hazel]

do custom flags work like that? what about abstact class Handler

the flag makes no sense then

if you can just use the event

[abstract spindle]

public WorldGuardManager(YourPlugin pl) {
        this.pl = pl;
        this.worldGuardHook = pl.getWorldGuardHook();
    }

public RegionManager getRegionManagerForWorld(World world) {
        RegionContainer container = WorldGuard.getInstance().getPlatform().getRegionContainer();
        return container.get(BukkitAdapter.adapt(world));
    }


public class WorldGuardHook {

    private final YourPL pl;
    public WorldGuardHook(YourPL pl) {
        this.pl= ül;
    }

    public void init() {
        Bukkit.getConsoleSender().sendMessage("WorldGuard Initializing Hook!");
        if (Bukkit.getPluginManager().getPlugin("WorldGuard") == null) {
            pl.getLogger().severe("WorldGuard Plugin not found!");
            pl.shutdown();
        } else {
            WorldGuardPlugin worldGuardPlugin = (WorldGuardPlugin) Bukkit.getPluginManager()
                    .getPlugin("WorldGuard");
            if (worldGuardPlugin == null) {
                pl.getLogger().severe("WorldGuard Plugin is null!");
                pl.shutdown();
            } else {
                Bukkit.getConsoleSender().sendMessage("WorldGuard Hooked!");
                Bukkit.getConsoleSender().sendMessage("WorldGuard Version: " + worldGuardPlugin.getDescription().getVersion());
            }
        }
    }
}

This is my register for the WordGuard flags

[upper hazel]

I mean how to register a class like this is it a listener right?

https://github.com/EngineHub/WorldGuard/blob/master/worldguard-core/src/main/java/com/sk89q/worldguard/session/handler/HealFlag.java

[abstract spindle]

No it has it has a Handler

https://worldguard.enginehub.org/en/latest/developer/regions/custom-flags/

[upper hazel]

public void onLoad() { - were he was find owerride

were class

lol now I understand all these custom flags can be replaced with regular polymorphism

[abstract spindle]

The HealFlag seams to be registered in the AbstractSessionManager.class

[upper hazel]

and means there are used their events?

hm

I even think that creating your own flag is bad for the blockBreak event. Better to create an event for each region and receive it via hashMap

although I don't know it's hard to say

[novel mauve]

how do you supercharge a creeper?

.setPowered() doesnt come up as an option in my IDE

[eternal oxide]

its only available IF you cast to a Creeper

[sage patio]

how i can teleport a player behind another player?

[eternal oxide]

Player#teleport 😄

[smoky anchor]

Creeper ent = (Creeper) ...

[novel mauve]

Im so dumb

thanks

[smoky anchor]

If you have this and hover over the Creeper, your IDE will tell you what is wrong

[sage patio]

well the problem is how i can teleport behind him 😁

[smoky anchor]

do some vector math with the players look direction

[chrome beacon]

Use the spawn method that takes a consumer

Otherwise you will spawn then charge

Instead of spawning charged

[novel mauve]

thanks but what do u exactly mean takes a consumer

[eternal oxide]

look or just location

[chrome beacon]

There's a method that's called spawn and it takes a consumer as a param

[novel mauve]

okay thanks

[sage patio]

something like this 2 - 3 behind

in the direction player1 is looking

[eternal oxide]

target.getLocation().subtract(target.getLocation().getDirection().multiply(-3))

or 3 depends on usind add or subtract

[gilded granite]

how do i create a 1.8 plugin with the minecraft development plugin

[chrome beacon]

You manually switch the dependencies in your pom

[gilded granite]

ok

[chrome beacon]

The development plugin does not support 1.8

[smoky anchor]

would teleport above player1 if player1 is looking down

[eternal oxide]

not using getLocation

has no Pitch

[smoky anchor]

wait what

[eternal oxide]

getLocation is the players body/feet

[smoky anchor]

huh never knew that, good to know

[eternal oxide]

getEyeLocation is the players head

[gilded granite]

1.8-R0.1-SNAPSHOT good?

[chrome beacon]

At least use the latest 1.8 version 💀

[gilded granite]

1.8.8?

[near mason]

theres a spawn method that takes a consumer?

[eternal oxide]

?jd-s yes

[undone axle]

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

[near mason]

oh thank you

i didnt knew it existed man

[sage patio]

is it possible to do not change the Y? when i look down the player flies

[eternal oxide]

you are using eye location

getLocation() not getEyeLocation()

[zealous osprey]

I just read "teleportScuffed" XD

[eternal oxide]

player#getLocation() is the location of their feet. It has no pitch

it does not matter where the player is looking

why are you teleporting the target?

teleporting the target behind the player

[sage patio]

the names are weird rn, i'm confused too

i just want to cuff someone

and the cuff plugin teleports him behind me

[smoky anchor]

can't wait to stand with my back to a wall

[zealous osprey]

What mc version, is it possible to make the cuffed player ride the other player?

[sage patio]

well thats a weird way to cuff someone

1.19.4

[zealous osprey]

Well then you don't have to teleport the player behind you and riding is "smoother".

[sage patio]

its very weired for a cop to carry someone in a roleplay server

[eternal oxide]

your code is fine. you must be doing something else odd.
Player#getLocation() is the location of the players feet. it has a zero pitch.
Player#getEyeLocation() is the players head which is where they are looking and will have pitch

[smoky anchor]

it is also very weird that the cop has the ability to teleport players into a wall

were it me, I would make a "bubble" from which the player can not escape
if the player does try, it pushes them towards the cop

[sage patio]

thats something cops can understand and they don't do that, but carrying someone while your're a cop? no

[zealous osprey]

Whaaat?!
This looks completely natural XD

[sage patio]

yea

for sure lol (why emojies are disabled in this server)

[zealous osprey]

If you rotate quick enough, you could maybe even fly away like a helicopter

[sage patio]

uh god

just tell me how can i teleport him

without changing the Y location

it works fine rn except the Y

[eternal oxide]

that is already how you teleport without changing Y

[smoky anchor]

create a variable from the player.getloc.getDirection
set the y to 0, normalize the vector, multiply by whatever
do the rest of the math

[eternal oxide]

If are getting a different Y when the player looks down you are not using Spigot

[zealous osprey]

If you want them behind you, take the vector of the direction the player is looking and invert the x and z components, multiply by some distance value V and set y to the y-level of the player?

Make sure to norm the looking direction vector

[eternal oxide]

lol so ott

Just use Spigot and not whatever fork you are using

a Player#getLocation() has zero pitch

[sage patio]

then waiting one hour to starting the server

[eternal oxide]

This is Spigot

?fork

[undone axle]

SpigotMC maintains the Spigot server. If you are using a fork of Spigot (such as Paper, Airplane, Purpur, or other derivative works), you should seek support in the appropriate Discord servers.

[gilded granite]

?export

[eternal oxide]

however, if you ask how to do it using teh players Eye location, then that will work on all forks too 🙂

[sage patio]

why should the paper change the methods they shouldn't?

[gilded granite]

?exporttoserver

[smoky anchor]

what are you trying to do

[gilded granite]

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

[smoky oak]

1sec

[sage patio]

on localhost or on a host?

https://github.com/Mohamad82Bz/RUoDeT

[smoky anchor]

do you not have localhost to test your plugins ?

[gilded granite]

localhost but i just forgeted the sitre

[smoky oak]

<plugin>
                <groupId>org.apache.maven.plugins</groupId>

                </configuration>
            </plugin>

[gilded granite]

no ik

[eternal oxide]

public void teleportTarget(Player player, Player target) {
  Vector eyeDirection = player.getEyeLocation().getDirection();
  eyeDirection.setY(0).normalize();
  target.teleport(player.getLocation().subtract(eyeDirection().multiply(2));
}```

[sage patio]

yea this one is working fine, thanks

it was because of paper or what?

[eternal oxide]

probably

you don;t need to zero pitch on Spigot as the player body/location has zero pitch on Spigot

[smoky anchor]

Honestly surprised the body has yaw or whatever at all.
thought only eye loc has it

[eternal oxide]

I can;t believe paper actually adds a pitch to the player location though

[sage patio]

when they cuff each other at the same time i've 2 supermans in my server

[eternal oxide]

server is single threaded for ticks so two players will never do it at the same time

[sage patio]

i know they just get teleported behind each other each tick

[eternal oxide]

you need to not allow a player to cuff another if they are already cuffed

[sage patio]

yea sure
