[viral temple]

remember when oil prices went negative

[noble lantern]

+rep for senior team

[lost matrix]

Intellij comes boundled with its own maven instance

[wet breach]

only for like a very short time window

[granite owl]

member when donald trump was still president? oh yea i member

[wet breach]

you had to be super quick to get in on that deal for the oil prices XD

[viral temple]

was better than free

[noble lantern]

uh oh were getting political

byebye

[granite owl]

xD

[slim kernel]

got this error tho:

[wet breach]

no nothing political

[viral temple]

economical*

[wet breach]

they were just pointing out what was better then free

XD

[granite owl]

hes replying to me

referencing the best series

ever

[lost matrix]

Then change the maven directory used by intellij

[wet breach]

wooo

7smile7 is here

I can leave now 😄

[lost matrix]

lul

[wet breach]

and the place won't fall apart chaotically

[slim kernel]

to what?

[noble lantern]

oh its the man who steals top slot on server boosters from me

[lost matrix]

path to your maven binaries

[wet breach]

he is very good 🙂

Also @noble lantern what happened to that test?

[slim kernel]

so the file I downloaded from there? https://maven.apache.org/download.cgi

[noble lantern]

couldnt get it working ngl

[lost matrix]

But bundled should work without any problems

[slim kernel]

yeah doesnt tho idk why

[noble lantern]

and compile takes 1 mins i got bored of recompiling to test

[granite owl]

i suspect my pom.xml isnt even setup properly but whatever, it works xD

[wet breach]

it isn't that hard to change the TPS 😂

[granite owl]

but i just left the namespaces empty

xD

[noble lantern]

i would of assumes it would be a variable

but nope

its probably something deeper than the main class

[lost matrix]

Yeah then just change the path to your maven bins

[glossy venture]

wouldnt you just divide 1000 by the tick time in miliseconds

[viral temple]

Oh boy, is this lag free?

[glossy venture]

to get tps

think it might be a local variable

in some method

[noble lantern]

the issue is theres no clear indication how the servers really processes those ticks

[lost matrix]

Its literally just a field. But changing it will result in weird behavior.

[noble lantern]

theres TPS = 20 but changing it past that doesnt change anything, unless /tps is lying

Plus was just doing it for fun

[granite owl]

@wet breach what would you say to my approach to write my own permission system using the scoreboard teams as its backbone? (its already working xD for the most part) xD

[lost matrix]

Wont be consistent because the runnables might be ran in different orders.

[glossy venture]

why do you want to change tps

[slim kernel]

get this now: Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project plertanixplot: Fatal error compiling

[noble lantern]

just wanna see what happens frost said it was fun

[lost matrix]

Whats the fatal error?

[glossy venture]

what would it be used for

i think it would rather use the tick time

[wet breach]

that it is terrible

[glossy venture]

for calculations

[lost matrix]

Look at how they did it:
https://www.spigotmc.org/resources/overdrive.73779/

[wet breach]

there is api methods in regards to permission related things

[slim kernel]

idk where can I look that up

[lost matrix]

Click higher in the hierarchy

[glossy venture]

ah

[noble lantern]

I think that plugins broken tbh

[lost matrix]

There you go. Invalid target release

[glossy venture]

theyre changing the minimum length the tick is adjusted to

[noble lantern]

unless that command is lying

and my changes did work when i changed them

[glossy venture]

is that with the plugin or your own code

[lost matrix]

Make sure to use the latest version of the maven shade and maven compile plugins.

[noble lantern]

both

[glossy venture]

ah

[noble lantern]

i know its not really possible with a plugin past jdk 12 as you cant edit public static finals really

already tried it

[granite owl]

ik

[slim kernel]

and where do I get them from?

[lost matrix]

https://maven.apache.org/plugins/

Just change the version in you pom

[slim kernel]

ohhh okay thank you a lot

[smoky oak]

can i force a scheduled task to wait until a different scheduled task finished?

[granite owl]

memory usage is so dumb

the server only deletes data when he needs memory

if u give it 32gigs itll first fill 32gigs before freeing memory

[lost matrix]

Kind of. What speaks against making the second task simply start another task after it finishes?

[noble lantern]

LMFAO

@wet breach

theyre fucking

teleporting

[smoky oak]

they're called unaware of each other, and passing one to the other would be difficult

[lost matrix]

How about you optimize your gc parameters. Then this wont happen.

[noble lantern]

i figured out the problem my spawn chunks has 10k tile entities somehow so i legit couldnt do 17tps

[lost matrix]

Would you mind explaining the overall task that you want the tasks to accomplish?

[noble lantern]

this is cursed oh nice laggy video

[smoky oak]

I have a config filled with 'effects' and a function that translates them into a hashSet of EffectPreset extends BukkitRunnable, iterates it and schedules them. The issue is that one of those effects is supposed to read in coordinates from a lodestone locked compass and another effect is supposed to use those coordinates. The reason they're separate effects is bc there's more than one effect that's dependent on those coordinates.

[granite owl]

from what ive learned, mc by default tries to keep as much in memory as possible like chunk data so players can move forward and backward in the map without reloading chunks every single time

but the way the server does so

is quite exentive

as its just swallowing all the memory for this

[lost matrix]

This can all be configured. You would need thousands of players in a world to "swallow" 32 gigs of ram

[granite owl]

at some point the cpu will be the problem anyway

[lost matrix]

Im not sure if i understand this. Whats the problem with the one task reading and the other task using the coordinates?

[smoky oak]

they have no relation to each other, they can't pass information to each other. It iterates through the entries in the config and translates them into the BukkitRunnable extending Effects & calls them

[gleaming grove]

Hi does Java has some handy way of loading Resource files to code?

[wet breach]

sounds like you just need to make a method that is intermediary that allows them to exchange information with each other

[lost matrix]

I hope you have something like a Map<UUID, LodestoneLocation> or some other centralised data structure that is accessible from both effects.

[smoky oak]

cant parse information. For that to work one would need toknow the UUID of the other wouldnt it?

[cursive loom]

Hey do you know why I can't do that ?

[lost matrix]

because setDroppedExp doesnt return an int

[cursive loom]

Thats say he want int ?

[lost matrix]

There is too much unknown information... Arent the effects per player?

[lost matrix]

Yes for the variable initialisation. Very basic Java.

[cursive loom]

So what he want ? 😂

[lost matrix]

To initialize an int variable you need an int...

[smoky oak]

no, they're in the config to get changed easily manually. it's something like this

effectList:
  effect_1: grab_coords
  effect_2: playsound_lightning
  effect_3: strike_lightning_at_cords

[lost matrix]

And they are being ran after another?

[smoky oak]

HashSet<EffectPreset> effectsMap = DetailsConfig.getEffectDetails(echo.r_details.getConfigurationSection(spell));
for(EffectPreset preset : effectsMap){
  preset.trigger_effect();
}

yes and no

the reason i ask if i can make one task wait for the other is because of the nature of HashSet to not have a ordered structure

[lost matrix]

Then why do you use it?

[smoky oak]

because the order of those effects isnt particularly important since they're all BukkitScheduler instances that call themselves

[cursive loom]

I do not understand what you want say

[lost matrix]

?learnjava

[undone axle]

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

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

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

[lost matrix]

But if one effect tries to grab coordinates and the next one needs those coordinates then the order is important. Crucial even.

[smoky oak]

yea but

even then theres still the issue of parsing the information from one task to the other

[lost matrix]

Ok let me show you a mock up.

[cursive loom]

I have my error I'm just not wake up 😂

thanks

[lost matrix]

Example number one:

public class EffectContext {

  private final List<EffectPreset> effectList = new ArrayList<>();
  private final Map<String, Object> dataMap = new HashMap<>();

  public void runAllEffects() {
    for (EffectPreset preset : effectList) {
      preset.trigger_effect(dataMap);
    }
  }

}

You use a List so you have a fixed order. You then simply pass a Map<String, Object> to every effect in order.
The first one can write something in there, the next one can read something and so on.
This would run all those effects in one tick after another.

[smoky oak]

being dependent on ConfigurationSectoin.getKeys() it would only work if that returned a usable list

but it returns a set not a list

[kindred valley]

when im trying to reach arraylist from another class it makes the arraylist empty why is it

[lost matrix]

Example number 2:

public class EffectContext extends BukkitRunnable {

  private final List<EffectPreset> effectList = new ArrayList<>();
  private final Map<String, Object> dataMap = new HashMap<>();
  private int currentIndex = 0;

  public boolean hasNext() {
    return currentIndex < effectList.size();
  }

  public void runNextEffect() {
    effectList.get(currentIndex++).trigger_effect(dataMap);
  }

  @Override
  public void run() {
    if (!hasNext()) {
      this.cancel();
    }
    runNextEffect();
  }

}

The effects will be run in order but only one per tick

[lost matrix]

Because you always create a new instance of that class. Simple java concept.

[smoky oak]

in either case how can i get the effects in their proper order

[slim kernel]

I cant reload the pom anymore now it says this. log: https://gist.github.com/ItzJustNico/6fba3978e8b12f387fab4d9b7fd3741a

[lost matrix]

Then dont use keys because they are useless here. Just make it a List of Strings:

effectList:
  - grab_coords
  - playsound_lightning
  - strike_lightning_at_cords

And then get it using FileConfiguration#getStringList()

[kindred valley]

thanks, i always tried to reach it with get

[smoky oak]

i use the keys so i can parse arguments to the functions via the config. For example, the volume, pitch, and relative coordinaet shift of the playsound_lightning

[lost matrix]

But i hope you dont use the keys to store any data...

[smoky oak]

no

[lost matrix]

Then i dont see why you would need keys

[lost matrix]

Restart your pc

[smoky oak]

because the keys indicate where to grab the configuration sections indicating the effects:

effects:
 a:
  type: sound
  pitch: 2.5
  shift:
   x: 10
   y: 0
   z: 10

[lost matrix]

So like this?

effectList:
  - grab_coords
  - playsound_lightning
  - strike_lightning_at_cords

Another yml

effects:
  playsound_lightning:
    type: sound
    sound: LIGHTNING_EFFECT
    pitch: 2.5
    shift:
      x: 10
      y: 0
      z: 10

How is your data structured

[smoky oak]

well like what i showed as example. 'a' is a generic key, and the function instantizing the effects does for(String key : section.getKeys(false))

i just number them 'a' 'b' 'c' etc because its fast

[wet breach]

fast in what way?

[smoky oak]

in typing in

[slim kernel]

still the same 😦

[smoky oak]

also its helpful to name them like that because if i want to indicate a more uncommon effect the name of the key doesnt matter

so i can name it like 'explosion_effect'

[lost matrix]

Im now completely confused how your data is even structured and i dont see any reason why you would need keys at all.

[wet breach]

I am not sure how you are dealing with the people here @lost matrix lmao

[chrome beacon]

I don't recommend running your server in a google drive folder

Anyways if no other server is running delete the session lock file

[lost matrix]

barely

[smoky oak]

?paste

[undone axle]

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

[smoky oak]

https://paste.md-5.net/ehohumukaq.apache
visual section

[slim kernel]

i dont even run a server i just wanna reload the pom

[pliant copper]

running a server in google drive bru

[smoky oak]

right click file -> maven -> reload

assuming you use an IDE

[wet breach]

i am not sure where else you would reload a pom or would need to 🙂

[slim kernel]

@smoky oak

[lost matrix]

What is the purpose of the key here?
And how do you even know what type of effect "a" is? By just the keys in that section?

[lost matrix]

Dont have your projects in drive folders and also delete the lock file.

[smoky oak]

i told you before the names of the keys dont matter. Their purpose is to separate the effects from each other. The key 'visual' is there because I have a scheduling class, which gets extended by different effect classes - audio, visual, and things permanently changing in the world

i iterate over each key in the sections 'visual', 'audio' and 'world', adding the effects to the HashSet and returning it to the main function, which then calls the for loop to schedule them all

[wet breach]

maven doesn't work every well in google or one drive directories because the software involved with syncing those directories with the services, locks the files and prevents maven from being able to use them. If that isn't the issue then the pom is opened up somewhere else.

[lost matrix]

That is a super weird and hacky approach...

[wet breach]

and inefficient

[smoky oak]

if it works without noticeable lag its good enough

again what i really need to do is to parse some information from one effect to the other

[wet breach]

yeah if you like degraded quality sure

[smoky oak]

hwo would you do it then

[wet breach]

probably something similar to what 7smile7 would do it lol

idk, when you got two pretty decent developers here confused in what you are doing or how you are doing it, odds are it probably isn't a very good way lmao

[lost matrix]

Still not 100% clean but its def better than what you are doing rn:

public class EffectContext {

  private final List<EffectPreset> effectList = /*load the effects in order*/;
  private final Map<String, Object> dataMap = new HashMap<>();

  public void runAllEffects() {
    for (EffectPreset preset : effectList) {
      preset.triggerEffect(dataMap);
    }
  }

}

Load them in order and pass some sort of data structure between them. From 0 to N.

[smoky oak]

about that... i remember having an issue with my IDE telling me its not possible to call a function with a HashSet<Item> when the parameter type was HashSet<Object>. Do you know why that is?

[wet breach]

I am assuming you were having issues in that it doesn't have a .get() method

[lost matrix]

Yes sure. A HashSet<Item> cant be implicitly downcasted to a HashSet<Object>.

[smoky oak]

HashSet<T> then?

[wet breach]

well if they were referring to casting, think they meant the other way

[smoky oak]

ah no

[wet breach]

but now we are getting into the realms of generics though

which I doubt you are ready to really mess with

[lost matrix]

Yes. If you want to allow any type of collection you can either do this:

  private <T> void call(List<T> list) {
    
  }

Or use a wildcard:

  private void call(List<?> list) {

  }

[wet breach]

also different types of generics

allow for different things too

[smoky oak]

where's the difference between T and ? then?

[lost matrix]

The one makes the method generic and the other makes the type a wildcard. It has a ton of implications depending on what you
are trying to do with the list internally.

[smoky oak]

im confused

[wet breach]

very good reason for you to not mess with generics right now lol

[lost matrix]

For example:
This is not valid

  public void otherCall() {
    List<String> elements = new ArrayList<>();
    String element = "TEST";
    call(elements, element);
  }

  private void call(List<?> list, Object obj) {
    list.add(obj);
  }

While this is allowed:

  public void otherCall() {
    List<String> elements = new ArrayList<>();
    String element = "TEST";
    call(elements, element);
  }

  private <T> void call(List<T> list, T obj) {
    list.add(obj);
  }

But lets stay away from generics for now...

[smoky oak]

maybe context for this one

public static boolean allOne(HashSet<HashSet<Object>> tHashHashSet){
        for(HashSet<Object> tHashSet : tHashHashSet){
            if(tHashSet.size()!=1)
                return false;
        }
        return true;
    }```
This function is uninterested in the data type the inner HashSet contains so i wanted to make it generic but neither Object nor T work here

[lost matrix]

Use a wildcard instead. Also: wtf

[wet breach]

lmao

[smoky oak]

worked thanks

[wet breach]

not sure if we should be worried about that

I suppose we find out when they come back and complain about something along the lines of they can't read from their generic method but can write to it or vice versa 😂

[smoky oak]

context for this one, i iterate through a list of locations and get all item entities in a bounding box of loc, loc.clone().add(1,1,1). I require that each of those bounding boxes contain exactly 1 item entity

[lost matrix]

You should use the lowest interface that still respects the liscov substitution principle.
So

  public static boolean allOne(Collection<Collection<?>> nested) {
    for (Collection<?> collection : nested) {
      if (collection.size() != 1) {
        return false;
      }
    }
    return true;
  }

This would have the same functionality but a broader use range.

[smoky oak]

oooh i see

noted

is that the reason getKeys returns a set?

[wet breach]

probably better if you use that instead of generics so you don't run into issues that you don't quite understand yet 🙂

[smoky oak]

wait isnt that again not able to get parsed?

[worldly ingot]

Funny enough, ? is probably better than Object there

Ah beat me to it lol

[wet breach]

lol

[smoky oak]

so wait

it can parse HashMap<HashMap<?>> to Collection<Collection<?>> but cant parse HashMap<HashMap<Item>> to HashMap<HashMap<Object>>

[worldly ingot]

Maps and Collections are different, so no

[wet breach]

well the first matches because it is using wildcard generics

[worldly ingot]

? is a wildcard so it could be either Item or Object

[wet breach]

the second way you are attempting to implicitly cast which isn't allowed in this way

[full forge]

How would I create an item? I want to override a BlockDropItemEvent, but the event.getItems() doesn't take ItemStacks

[smoky oak]

wait what does HashSet have that Collection doesn't?

[wet breach]

a set

[worldly ingot]

HashSets are Collections, they're just a more specific type of one

Collection -> Set -> HashSet

[smoky oak]

i mean in functionality

as in

why use hashset instead of collection

[wet breach]

Order I suppose?

[worldly ingot]

Sets don't allow duplicates and aren't ordered, but HashSets operate on the hash values of objects so #contains() operations are faster

[wet breach]

oh right there we go

[lost matrix]

Because it contains Items instead of ItemStacks. You can remove Items from there to prevent them from dropping.
Adding is now allowed.

[full forge]

Yes, I want to add items, but how would I actually make an item to add

[smoky oak]

Use set when you dont do contains() then?

[worldly ingot]

If you want to take a peek at the Collection interface on the Javadocs (https://docs.oracle.com/en/java/javase/18/docs/api/java.base/java/util/Collection.html) you'll find a lot of different types of collections that all serve a different purpose and fit best in different situations

[lost matrix]

Note: There are some sets that maintain an order like TreeSet or LinkedHashSet.

[worldly ingot]

Mhmm

[smoky oak]

i used this as a guide thus far

[worldly ingot]

I guess order isn't really a specification of a Set, just a HashSet

[wet breach]

Well someone is certainly getting a free lesson in advanced java this morning lol

[worldly ingot]

Yeah, List/Set/Map are probably the three you'll use most often

ArrayList/HashSet/HashMap implementations generally

Until you explore alternative options you'll be okay with those lol

[lost matrix]

You listen for the BlockDropItemEvent and simply spawn additional Items on the broken blocks location.

[smoky oak]

well every bukkit plugin ever I've seen has used HashMap instead of Map

[worldly ingot]

BlockDropItemEvent gives you a mutable list, doesn't it?

[full forge]

Yes

[lost matrix]

I thought that adding items wanst allowed. Only removal.

[worldly ingot]

Yeah, https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/block/BlockDropItemEvent.html#getItems() is mutable. You can add a drop to it

Oh you're right

mbmb

No additions

[wet breach]

You should use the highest type when possible and not the lowest. Unless you making an API and sometimes it is quite the opposite

[worldly ingot]

You'll see Map<K, V> map = new HashMap<>() very, very often as you really don't need to know the implementation type in most cases

It provides no benefit

(again, in most cases*)

[smoky oak]

I'm more curious about the reason to use HashSet instead of Set. I dont call contains() at all

[full forge]

My problem is whever I make an item using new Item(), it wants me to override all methods in the class. Obviously I'm using the wrong constructor, so how should I properly do this

[lost matrix]

Use World#dropItemNaturally(Location, ItemStack)

[worldly ingot]

Maybe not right now you don't, but you may only use #contains() exclusively in other scenarios

[glossy scroll]

And not ConcurrentQueueLinkedTreeHashMapSet?

[worldly ingot]

What if you're keeping track of a set of player UUIDs that are able to perform some functionality?

You'll add to/remove from it, then #contains()

[full forge]

Ok, thanks :D. Wouldn't have thought of that

[worldly ingot]

(though for reference, a HashSet is a Set much like how a HashMap is a Map)

[smoky oak]

Oh i havent meant overall. I meant is there a reason to, in an instance i know i will not call contains(), to still use a HashSet

[worldly ingot]

Maybe. If you aren't iterating either (because iteration tends to be slower in sets) but you don't want duplicates, a Set is probably ideal over a List

It's all extremely situational

[glossy scroll]

Duplicates

[chrome beacon]

Ah yeah my bad not a server. Solution still applies. Make sure only one instance is running and delete session lock

[smoky oak]

Ah that would be a reason. I do iterate that HashSet in particular quite often

also Set still cannot contain duplicates right?

[glossy scroll]

Dont optimize your code before writing it

[smoky oak]

I've written most of it already

[glossy scroll]

All set implementations do not have duplicates

[glossy scroll]

Well still dont optimize it

If it doesnt need to be

[smoky oak]

to clone my earlier question

spawning 40000 Particle.DustTransition in causes them to appear over a few seconds in the order they're initialized in, but the method is supposed to run in one tick (50ms) and also tells me it finishes in that time in the logs. Any idea why?

so yes

optimization might be useful here

if i ever find out the reason it doesnt work like it says it does

[glossy scroll]

I dont think you will be able to do this in one tick

[smoky oak]

the server says it works in one tick

it also says if i call /tps immediately afterwards that the tps of the last 5 seconds was 20.0 tps

[glossy scroll]

Well the problem is

You have to send 40,000 packets to the player

Thats easy

Sending packets is easy

I think there would be a client limitation at this point

They may not be able to receive all of these at the same time

[smoky oak]

i recall that issue not happening with lower amounts of particles

but i use so many to generate a continuous shape

[wet breach]

While this may be true, you shouldn't limit yourself to API options just because you are not making use of them. There isn't any loss of benefits by using a HashSet over a Set even if you are not making use of the extended features in fact you have more benefit because later down the road you won't have to spend time refactoring code because it turns out you do need that extended functionality.

most of the time where you have to worry about these things is if you are making an API where you would return the lowest type instead and let the user decide if they want to make use of a higher type because you don't know what the user would want.

[slim kernel]

What do you mean running there is nothing running I just want to reload the pom and where is that session lock?

[smoky oak]

doesnt set still have the contains function? wouldnt the onyl thin i need to change be the implementation method behind the instantication of the set?
Set<Item> itemSet = new Set<>() -> Set<Item> itemSet = new HashSet<>()

[glossy scroll]

You cant instantiate Set on its own

Its an interface

[smoky oak]

well that answers that question bruh

imma take a break and then deal with the part of my code thats not working

[glossy scroll]

Im very confident youve just reached a mc limitation

Also 40,000 packets

[wet breach]

that sounds ideal since you basically got a crash course into some advanced java stuff 😛

[glossy scroll]

Thats a lot of data

Players may hit throttling if their ISP sees that!

[wet breach]

40k packets is nothing 🙂

[smoky oak]

im unsure if its 4k or 40k packets

[glossy scroll]

40k would be a lot

[smoky oak]

i call spawn particle 4000 times with 10 particles each

[glossy scroll]

I usually try to keep lower than 1200 for complex visuals

[glossy venture]

spawn particle packet contains the amount i think so it would probably be 4k

[glossy scroll]

You can also use the debug screen in minecraft to see if your client is receiving all the packets

[smoky oak]

where?

[glossy scroll]

Its in the packet?

You can specify amount

[smoky oak]

no in the debug screen

[glossy scroll]

Oh

[wet breach]

if each packet is 60bytes which is their max size, that is only 2.4mb of data

[glossy scroll]

https://minecraft.fandom.com/wiki/Debug_screen

[smoky oak]

must be a client issue then

[glossy scroll]

“rx”

[glossy scroll]

I mean 2.4mb is still significant

[smoky oak]

is tht over the lst second?

[wet breach]

yes and no, network hardware pads out the packets to their max size usually 🙂

makes it easier to handle in this manner

[glossy scroll]

Im just thinking like

That requires around 20mbps internet

Which most have

But a decent chunk dont

[wet breach]

while true, the packets are not sent or received all at once

[glossy scroll]

I think these are?

[wet breach]

so while total it is 2.4mb they are not coming down the pipe all at the same time

[smoky oak]

it goes up to 5000 rx over a few seconds then drops down

[glossy venture]

isnt rhere some conpression on the minecraft networking

[wet breach]

yes

[glossy venture]

so it will prob be a bit lower than 60 bytes/packet

[wet breach]

doesn't change tcp packet sizes though, just changes the size inside of the packets themselves

[glossy venture]

oh

tcp

yeah

[glossy scroll]

Should emphasize i have no real expertise

[glossy venture]

me neither

[glossy scroll]

So take anything i say with a grain of salt

[glossy venture]

lmao

[wet breach]

well networking is actually an area where I am an expert at 🙂

[glossy venture]

nice

[wet breach]

didn't take 52week course in Satellite communications to not know anything 😛

[glossy venture]

lmao

[glossy scroll]

idk maybe yoy can help with this problem

The issue is trying to send 40k packets alledgedly

Theyre not all appearing at once like he wants em to

[wet breach]

however while the packets are padded to 60bytes, the nic will discard those empty bytes upon receiving 😉

[glossy scroll]

Server says they were all sent in a 50ms interval

[wet breach]

well this is going to be probably an issue along the route as well as the receiving ends hardware and setup

[smoky oak]

wait a fucking second
I just sent a quarter million particles in 25k spawnParticle calls stretched over 2 seconds

no lag

[wet breach]

while the server may have sent those packets, that doesn't mean none of them needed to be re-transmitted

TCP requires acknowledge packets in return

if it doesn't get one, it will send a new one

[smoky oak]

so if the client cant recieve that many packets they get resent

[midnight shore]

hi! How can i set an item to be unpickable from the ground?

[smoky oak]

resulting in the stuttering display?

give it a tag in pdc then cancel whatever event is called when it get spicked up

[wet breach]

yes, but what I explained is an over simplification

there is a lot more to it

[midnight shore]

would this work?

[wet breach]

that isn't how it works

network hardware takes care of the re-transmitting the mc server wouldn't even know about it

[glossy scroll]

Ya

[wet breach]

oh talking about something else

[glossy scroll]

Also i believe there is a packet loss metric

[smoky oak]

i meant client side

server side there seems to be no issue considering the function finishes within one tick

[wet breach]

yes but this only applies if the client knows it was supposed to receive it

so if the server sends 40k packets, the client doesn't know it was suppose to get 40k packets

[glossy scroll]

Right

Server does

Just unsure if there is any feasible way to know

Probably not

[wet breach]

you would need a mod of some sort on the client

to report back to the server

[glossy scroll]

Mhm

[wet breach]

IE, you send 40k packets, client then reports back to server how many it got

[smoky oak]

hm i recall one of the things i tried - i set the particle display to decreased

can you spawn in particles without nms that only those whose setting is all see

[wet breach]

however though most of the time 40k packets isn't an issue for most people

minimum down speed someone would need for that is 5mb/s

maybe even 2 or 3 would just be fine too

[glossy scroll]

Right but theyre all at once

In this case

[wet breach]

client tick rate is the same as that of the server

so as long as they can get all the packets in 50ms

or even 100ms

then it shouldn't be an issue lol

[glossy scroll]

Right well that doesn’t explain why its not working

[smoky oak]

no it does work

it stutters

but the server says theres no lag at all

must either be the client or the transmission then

[wet breach]

well that is going to be more of a case of client lag then it is a network problem

if the client can see all the particles but it is stuttering then that means the client got all the packets or most of them anyways

[glossy scroll]

Ya thats what i said

[smoky oak]

well theres no actual lag on the client

but the particles appear over time

not at once

[glossy scroll]

How much over time?

[wet breach]

server lag isn't going to affect the displaying of the particles on the client side

I bet the server is throttling the sending of the packets

throttle limit is for both tx and rx

[smoky oak]

uh if i spawn in about 2000 * 10 particles

[glossy scroll]

Yea yhats also something i was thinking

[smoky oak]

SOMETIMES they appear over time

[glossy scroll]

Hardware or mc?

If its mc i would just recommend using protocollib

[midnight shore]

https://paste.md-5.net/wedafidago.apache whats this error?

[wet breach]

I am thinking its client related

[glossy scroll]

Wrong pdc data type or smt

[wet breach]

if you wanted to be sure it wasn't hardware related, send a custom ping packet from your server terminal that is 60bytes to the client system

[smoky oak]

the weird ting is that while it may stutter one time, the other time it eats three times as many particles without any issue

[midnight shore]

?? how could it be wrong?

[glossy scroll]

Data type mismatch

E.i you are getting and int when it really is a double

[wet breach]

@glossy scroll for not being an expert in networking at least your intuition wasn't off base either 😛

[glossy scroll]

Well i had to make tornado in mc

And faced a little bit of stuttering

[midnight shore]

in the error it says NBTTagByteArray

but i never mention arrays

[glossy scroll]

Darn i cant find the gif of my tornado

[wet breach]

lol

[wet breach]

does it tell you about where the offending line is?

[midnight shore]

man this is the error

[smoky oak]

he means 'shouldnt there be a caused by below that'

[wet breach]

you misinterpreted the error

you are trying to store an integer when it wants a bytearray

[midnight shore]

but how could it 'want' an array?

i'm storing in a pdc

[smoky oak]

you need to declare thedata type youre storing in a pdc

it only allows primitives, byte array and string

[wet breach]

need to serialize your data or put it in a string

[midnight shore]

true! but i'm using a library from @tender shard

[wet breach]

doesn't mean it is perfect 🙂

[midnight shore]

thats the DataType thing

[wet breach]

or you are not using it correctly lol

[glossy scroll]

Youre trying to store an integer where an array already exists

That is the issue

[wet breach]

I am not familiar with alex's lib

[midnight shore]

it worked perfectly until now and also i stored integers really well

[eternal night]

I mean, you are clearly accessing one value as an int and then the same value as a uuid

[glossy scroll]

The error doesnt lie

[midnight shore]

so i don't really understand whats wrong

[wet breach]

I can only tell you what the error means

and as martoph said

it doesn't lie lol

[eternal night]

whatever value is stored under WillowCore.entity_data

[wet breach]

well that isn't true

[midnight shore]

UUIDs?

[glossy scroll]

Do not claim to have perfect code if it errors out

[wet breach]

rarely it lies about the error 😛

[eternal night]

you read it once as an DataType.INTand once as a DataType.UUID

[midnight shore]

oh my god

i'm dumb

i had a typo

in the namespace name

[eternal night]

👀

[glossy scroll]

That explains

[wet breach]

I do hate it when java lies about the error though

glad that isn't a common thing for people to complain about when they come here 🙂

[gleaming grove]

how can i get the server IP adress in my plugin?

ok nvm

[tardy delta]

what does that mean?

[granite owl]

11.04 14:19:21 [Server] Server thread/ERROR Error occurred while enabling PlayerControl v1.0 (Is it up to date?)
11.04 14:19:21 [Server] INFO java.lang.ClassCastException: class java.util.HashMap cannot be cast to class java.lang.String (java.util.HashMap and java.lang.String are in module java.base of loader 'bootstrap')

rankPermissions = (HashMap<String, ArrayList<String>>) Utils.deserializeFromFile(permissionFile.getPath());

is it not possible to serialize/deserialize an object

like a hashmap

that holds another arraylist?

public static HashMap<String, ArrayList<String>> rankPermissions = new HashMap<String, ArrayList<String>>();

[glossy venture]

where does the error occur

[granite owl]

with this line

it serializes just fine

ive read the file

but when its supposed to deserialize the object

[glossy venture]

weird

[granite owl]

it throws an error

[noble lantern]

Error says your cating hashmap to a string though?

[granite owl]

but code says im not

[glossy venture]

when are you casting it to a String wtf

[granite owl]

im casting a hashmap holding a string as key and an arraylist as value

ik it says im casting it to a string

but i dont see where

thats lit a 3liner so far

[noble lantern]

Gson deserializes and dsrializes though so it should be possible

String lists*

[hasty prawn]

It is possible

[granite owl]

the arraylist itself holds strings ya

but yet again, im not casting to a string im casting to a hashmap holding those members

[noble lantern]

Has to be the way your storing it

[granite owl]

public static HashMap<String, ArrayList<String>> rankPermissions = new HashMap<String, ArrayList<String>>();

@SuppressWarnings("unchecked")
    public static void loadPermissions()
    {
        File permissionFile = new File(Utils.getOwnDir + "/RankPermissions.bin");
        
        if (permissionFile.exists())
        {
            rankPermissions = (HashMap<String, ArrayList<String>>) Utils.deserializeFromFile(permissionFile.getPath());
        }
    }

public static void savePermissions()
    {
        Utils.serializeToFile(rankPermissions, new File(Utils.getOwnDir + "/RankPermissions.bin").getPath());
    }
``` this is the whole code

so far

its like nothing

[noble lantern]

Ack im on my phone

Hard asf to read on mobile lmao

[granite owl]

ik

[noble lantern]

Whats it look like when stored in a file also whats serializeToFile method look like

[granite owl]

Utils.getOwnDir works fine, it just gets a static reference to the main class and then parses it to its own directory

so i can move plugins in different directories and they still find their own directory

where theyre supposed to store data

[noble lantern]

Wait ik

DeserializeFromfile

Does that returns a string itself

And not a type of Map

[granite owl]

it returns Object

i kept it generic

sec

[noble lantern]

Check if its instanceof String

[granite owl]

it already works

with a hashmap

holding <string, UUID>

[noble lantern]

Oh idd

Odd*

[granite owl]

sec

this is still more or less from a tutorial which ive alternated to fit my needs

public static Object serializeToFile(Object obj, String str)
    {
        try
        {
            ObjectOutputStream s = new ObjectOutputStream(new FileOutputStream(str));
            s.writeObject(obj);
            s.flush();
            s.close();
            
            return 0;
        }
        catch (Exception e)
        {
            return e;
        }       
    }
    
    public static Object deserializeFromFile(String str)
    {
        try
        {
            ObjectInputStream s = new ObjectInputStream(new FileInputStream(str));
            Object ret = s.readObject();
            s.close();
            return ret;
        }
        catch (Exception e)
        {
            return e;
        }
    }

and kept a few placeholders where i dont need them like the return value just in case

[midnight shore]

How can i listen for the Enderchest open event?

[granite owl]

InventoryOpenEvent check if instance of players enderchest

[midnight shore]

ty

[tardy delta]

Map<String, List<String>> ranksPermissions = new HashMap<>(); :)

[noble lantern]

Hes loading data

Oh wait

Not there

Mb

[granite owl]

did i initialize it incorrectly?

[noble lantern]

That might fix it

Worth a try

[tardy delta]

ye but it looks ugly

[granite owl]

tho this works fine too

public static HashMap<String, String> defaultMsgs = new HashMap<String, String>();

im keeping a bunch of config data in memory yes

[noble lantern]

Maybe you need to serialize the List too

Just a thought not sure though

[granite owl]

serialize the list on its own?

[tardy delta]

never worked with serialisation 👉👈

[granite owl]

its anoying to get into

but its very handy

[noble lantern]

I just let gson handle it

Ez

[granite owl]

imagine writing pagefiles when ur provider only gives u 4gb ram

[tardy delta]

its just maps and objects :}

[granite owl]

cough

i would never do that ofc

[hasty prawn]

Fantastic until Gson does something stupid

[noble lantern]

We dont talk about gsons stupidites

Theyre features

Okay?

Jackson has that feature too

ObjectMapper

[granite owl]

im going to try just for a quick debugging to change the data type of the hashmaps value members

doesnt matter since its an empty snipped so far anyway

[hasty prawn]

"ok Gson go save this int"
"ok"
"Can I have that back now Gson?"
"yes but I put a .0 at the end so now it's a double"

[granite owl]

so its storing 2 strings instead of an arraylist

[tardy delta]

🤣

[granite owl]

but that shouldnt make a difference

because all hashmap, arraylist and string inherit Serializable

implement*

[noble lantern]

NodeJS does the same bullshit sometimes

Though not as serious in Java, still annoying

[granite owl]

ik what the problem might be

i keep storing the same corrupted arraylist

from before

nope

still corrupted

wtf

why wont it load its both strings now

even my uuid works

[restive tangle]

How would I go about making a server selector in Bungee? What I think I'll try is make a command in bungee and whenever I click on an item in the server selector inventory I run the command with the name as the argument

[tardy delta]

can someone explain me what bungee actually is?

[maiden thicket]

though in js its just "number"

[tardy delta]

is it just an api to work with mmultiple servers or what?

[maiden thicket]

a proxy that bridges multiple servers together basically

player connects to proxy

player connects to server thru proxy

[tardy delta]

what is a proxy :kekw:

[maiden thicket]

well the way i think of it its like an extra layer

[noble lantern]

In nodejs you can check its type :p

[maiden thicket]

node.ts 😎

[tardy delta]

a layer of networking stuff?

[maiden thicket]

basically?

i guess

[glossy venture]

manages and redirects connections to servers

just forwards the packets

[maiden thicket]

that

[glossy venture]

but you can handle them before they reach the actual servers

[noble lantern]

Ts i nice for js ngl I love having explicit types

[glossy venture]

and you can teleport players to other sevrers

[maiden thicket]

but proxy doesnt send game packets and stuff

[glossy venture]

yeah

it forwards them

[noble lantern]

And not some wildcard variable that thinks it can be everything

[glossy venture]

it doesnt send any

iirc

[maiden thicket]

it'll send the casual handshake and login probably

[glossy venture]

oh yeah

[maiden thicket]

but for game packets thats from the backend

[glossy venture]

yeah

it does the authentication

[tardy delta]

oh

[granite owl]

okay ive copied it 1:1 from my working project

its still not working

so i guess ik where to look at

and ive found it im so dumb

@noble lantern

public static Object deserializeFromFile(String str)
        {
            try
            {
                return (String)DeserializePtr.invoke(UtilsPtr, str);
            }
            catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException e)
            {
                e.printStackTrace();
            }
            
            return null;
        }

[tardy delta]

try return kek

[granite owl]

ive already fixed it

its working now

the problem was that i actually access the method using reflection

and my wrapper function was returning a string because ive copied that wrapper from alot functions

because i outsource all standard methods i use into another plugin to access them via well reflection

[restive tangle]

Do custom channels we register in BungeeCord act the same as the default BungeeCord channel?

[sterile token]

Im a bit annoyed trying to do this in block place event

• If claim exists, allowed players to place blocks (if they are inside the users)
• if claim doesnt exists claim another

[hasty prawn]

whats annoying about doing that

[sterile token]

I have this code but im not secure about it

@EventHandler(priority = EventPriority.HIGHEST)
    public void onPlace(BlockPlaceEvent event) {
        Player player = event.getPlayer();
        Claim claim = this.claims.getClaim(event.getBlock().getLocation());
        if (claim != null) {
            if (claim.getUser(player.getUniqueId()) == null) event.setBuild(false);
        }
        this.claims.create(new Claim(player.getUniqueId(), "test", event.getBlock().getLocation()));
    }

[tardy delta]

are you storing every block of the claim?

and after that i asked what a proxy is

[sterile token]

No, just the location

[tardy delta]

well every location of the blocks of the claim?

[sterile token]

My claims are based on 1 location (the center block)

And them virtually im creating 2 corners

[tardy delta]

uh lol

[hasty prawn]

Well you know you're always making a claim right?

Whether there's one there or not.

[sterile token]

Oh

I jsut realized that

Im so dumb

[tardy delta]

im thinking that you have a weirdly designed claim class

[sterile token]

I explain, the claims have 1 location, and them i convert that location into a cuboid (to generate 2 virtually corners)

[tardy delta]

what if players place a block on a location that is not the middle of a claim, will that allow them to place or not?

[hasty prawn]

Yeah that's a fine way of doing it.

[tardy delta]

wait its correct

thought you were using claims::contains

[hasty prawn]

oh god

[granite owl]

gotta tell u, as long as u dont expect a user to manually update the file like for example using a config file, serialization is so useful esp because its super easy to use.

[sterile token]

No i will send full code

So you can understand it better

[granite owl]

also for networking

[tardy delta]

the hell is event.setBuild(false) tho

since when is that method there

ye

i was thinking that

ah lol there's actually a method setBuild

[undone axle]

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

[tardy delta]

screenshots on linux go brr

nah just shareX and press ctrl + printscreen

and it automatically copies the screen to your clipboard

🤔

sharex is only windows

:(

screen capturing thing

its easier than pressing a few buttons

[hasty prawn]

I only use ShareX if I want to make a gif

[tardy delta]

i always used it

its just easy

[opal juniper]

i have one of my mouse buttons bound to snipping tool

best decision ever

[tardy delta]

lol

i could technically do that too

[sterile token]

Dessie and Fourteen this how looks now:

@EventHandler(priority = EventPriority.HIGHEST)
public void onPlace(BlockPlaceEvent event) {
  Player player = event.getPlayer();
  if (!event.getBlockPlaced().getType().equals(Material.BEACON)) return;
  Claim claim = claims.getClaim(event.getBlockPlaced().getLocation());
  if (claim == null) claims.create(new Claim(player.getUniqueId(), "test",      event.getBlockPlaced().getLocation()));       
}

[tardy delta]

i got a button which is basically ctrl now

[lilac dagger]

why not use the window's snipping tool and just press prt scr

[tardy delta]

no need for equals, == comparing for enums is fine

[sterile token]

I seen and still wrong the code

[tardy delta]

idk lol

[sterile token]

That why im so messier lmao

Because i need to:

• Create claims when a claim doesnt exists on the location and if block placed is beacon
• If claim exists, allow to place blocks (the owner) and his team users

[tardy delta]

is there a map with the claims?

i would do java Location loc = event.getBlockPlaced().getLocation(); Claim claim = claimsMap.computeIfAbsent(loc, () -> new Claim(player.getUUID(), "test", loc));

or well instead of new claim just claims.create

returns a claim too i guess

claims.create(new Claim()) wha-

[grim ice]

no wtf

[tardy delta]

heh?

[grim ice]

u cant have duped keys in a map

and even if u can u shouldnt do that

ur gonna have a few ten thousands of entries for each claim

[tardy delta]

i know that, computeIfAbsent just creates a new claim or returns the claim if it exists in the map

[grim ice]

bro

[sterile token]

Also my claim its nto a map

Its just a Set<Claim>

[grim ice]

u shouldnt use that type of map

anyways

ur map will look like this according to ya

HashMap<Location, Claim>

which sucks ass

[sterile token]

Hex

That why im using a Set<Claim>

[grim ice]

Exactly

[sterile token]

So im messed in the event

[tardy delta]

then tell me that >_<

[grim ice]

having an entry for each block in the claim

is absolutely garbage

[sterile token]

Hex

Can i explain?

[grim ice]

sure

[tardy delta]

when im done with rust i'll make a claims plugin too

[grim ice]

there are many

[tardy delta]

and a home plugin.. smh soo much more to do

[grim ice]

no one will ever make something better than the existing one

I wouldnt bother

and even if you do

no one will use it

[tardy delta]

i dont care about making it better i just want to try to make one

[grim ice]

oh ok

[sterile token]

My claim store (owner, name, location, team users)
For checking the blocks inside the claim i use a cuboid class

So i store a single location of the claim (the centered block)

Because its a block protection plugin, so the claims should be created base on a center block and protect all blocks around in a radius

[tardy delta]

mwe

[fleet pier]

How do i get the port of the spigot minecraft server?

I know how to get the ip address but there is no get port method

🤔

[tardy delta]

getServer().getPort() i guess

[sterile token]

Yeah

[fleet pier]

bruh

[tardy delta]

it is there :)

[sterile token]

And maybe try using a good IDE or use github copilot

[fleet pier]

i was trying to work with

MinecraftServer minecraftServer = MinecraftServer.getServer();

[sterile token]

No that no the spigot api

[tardy delta]

dont work with the implementation lol

the impl isnt probably aware of the port

[sterile token]

Fourteen

S owhat do you u recomemnd?

[grim ice]

of what though

[tardy delta]

uhh about what

[sterile token]

Could u read my explanation?

[tardy delta]

lemme write something rq while u try to explain

[sterile token]

I already explained

[sterile token]

there its start

[grim ice]

Well that doesnt look awesome design

[sterile token]

Why?

Do you know a better way?

[grim ice]

where da abstraction sir

yes

[sterile token]

Oh u can help me a bit?

[grim ice]

and not all cuboids work with radiuses

yes

make a Cuboid interface

[sterile token]

Allr

Done

[grim ice]

make your class atm called RadiusBasedCuboid

or RadiusCuboid if u want

[sterile token]

ok

[tardy delta]

are you on java16+?

[grim ice]

then make it implement the Cuboid class

with the methods that are for a cuboid

like

contain() etc

any method related to radiuus shouldnt be in cuboid interface

and override them in radius implementation of Cuboid

and later if you want to

u can just implement Cuboid

to make a

SimpleCuboid or smth

which accepts 2 locations

[sterile token]

Hex, So cuboid interface should contains methods:

void expand(T location)

boolean contains(T location)

T getPos1()

T getPos2()

[tardy delta]

verano do you have access to records?

so java 16 or smth

[sterile token]

No sorry

[tardy delta]

np

[sterile token]

Im trying to do cuboid multi version

So be able to use it from 1.8 to 1.18x

If not i would be using BoundingBox

😮‍💨

[grim ice]

I mean sure

you wanna make it generic?

I mean that makes sense

since not all cuboids are bukkit location cuboid

[granite owl]

short question cause i cant test it rn, if i do String.replace("{break}", '\0'); will this cut the rest of the string off as it would in C?

[rancid snow]

no.

[grim ice]

cut the string off?

[granite owl]

using a null terminator character

[rancid snow]

that happens because c has null terminated strings

java doesnt

[sterile token]

Hex i make the interface generic, because you can have location cuboid or vector cuboid

[granite owl]

aight teye

[sterile token]

But the difficult thing for me its the math lmao

Because based on 1 location i should calculate 2 corners

[grim ice]

that wont work anyways

[sterile token]

Hex can i letter dm u?

[grim ice]

String.replace is not static

[grim ice]

No

do it here

[sterile token]

Allr

But dont yo u get mad i tag so you dont orget the message?

Because if you dont tag then you lost messages

I had many times losted my questions

Because this chat its so active

[grim ice]

its fine

[grim ice]

yeah

makes sense

[grim ice]

UHH

i failed in math cant help u with tha

LOL

[sterile token]

Yah dont worry the cuboid class i had was working great

[glossy venture]

also always get the -X -Y -Z corner and X Y Z corner

[sterile token]

So i just need to do it inside RadiusCuboid

[sterile token]

private double x1, y1, z1;
    private double x2, y2, z2;

    public Cuboid(Location location, Double radius) {
        this.x1 = location.getBlockX();
        this.x2 = location.getBlockX();
        this.y1 = location.getBlockY();
        this.y2 = location.getBlockY();
        this.z1 = location.getBlockZ();
        this.z2 = location.getBlockZ();
        this.inflate(radius);
    }

    void inflate(double x, double y, double z) {
        if (x != 0) { x1 -= x / 2; x2 += x / 2; }
        if (y != 0) { y1 -= y / 2; y2 += y / 2; }
        if (z != 0) { z1 -= z / 2; z2 += z / 2; }
    }

    boolean contains(double x, double y, double z) {

[glossy venture]

so do like some Math.max and Math.min shit

[sterile token]

That work really wells

[glossy venture]

yeah but if the second corner is at -X -Y -Z it wont

so make sure the first is always - and 2nd always +

[sterile token]

Oh

So how i can do it?

can u do the math part if it doesnt fuck to you?

[grim ice]

hes saying

it should always be

0,0,0;1,1,1

OR

always

1,1,1;0,0,0

so you know for a fact the bigger position

[sterile token]

Hmn im dumb with math

😡

[glossy venture]

well with the radius it works

always

[grim ice]

@granite owl

    System.out.println("{break}".replace("{break}", String.valueOf('\0')));

this will return nothing

[glossy venture]

but if you need two arbitrary corners it might be useful to force them to be correct

[grim ice]

just a line break

[sterile token]

And it most diff because its a 3d, so i dont just have an x and z i also have Y that i dont know how it works

I will have to read about x, y, z

[tardy delta]

whats now the problem in fact?

[grim ice]

it sounds easy

to get it from radius

just get paint

and draw

[tardy delta]

dunno why i was writing this but ye

[sterile token]

Works great?

[lost matrix]

Another bootleg BoundingBox?

[tardy delta]

nah i decided to write smth for verano

[echo basalt]

Math.min, Math.max

[tardy delta]

i forgot whats the problem actually lol

[lost matrix]

@sterile token Just use Spigots BoundingBox

[sterile token]

I cannto since i want my cuboid support 1.8x until 1.18x

If not i would already be using it

[tardy delta]

i hate maths lol

[sterile token]

Which is the math to calculate 2 (3d) corner based on 1 centered location and a radius

[lost matrix]

Then copy paste the class from spigot.

[echo basalt]

did you fail 3rd grade geometry

center.add(radius, radius, radius)
center.subtract(radius, radius, radius)

[tardy delta]

i just pasted it

basically

[sterile token]

I never had geometry its my first year of computer science im just 15y im a child lmao

[tardy delta]

wait what circles in mc 🤔

[lost matrix]

Or you could just literally copy paste BoundingBox from spigot because it will work in all versions.

[echo basalt]

ehh still

[sterile token]

😂

That why im so dumb

[tardy delta]

i just like to draw stuff down when i need to do maths

especially geometry

[echo basalt]

your age shouldn't really matter for these basic things

[sterile token]

Minecraft terrain:

= claim block

$1 = corner 1
$2 = corner 2

--$1----------------

--------#---------
--------------$2----

[tardy delta]

and what are you trying to calculate?

[glossy venture]

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

verano

[sterile token]

I did the draw

[glossy venture]

i wrote some simple class

[sterile token]

Oh oik

Really thanks people

I will check all your suggestions and accept then

That why i love this community

[tardy delta]

is that contains method properly working? because you have to check if the provided x and y are between the x and y of the obj

[sterile token]

Because other people will say me "Verano, dont fuck with cuboid and use WorldEdit"

[sterile token]

Isnt the same code i send?

[glossy venture]

when

it does calculations to ensure the first corner is always the smallest and the second the largest

[tardy delta]

isnt this supposed to do it

ah the first is the smallest

[glossy venture]

yeah

[tardy delta]

lol

[glossy venture]

that would work too

doin git in the checks

[tardy delta]

im still wondering what hes doing

anyways is Object#clone returning an object with the exact same fields and stuff as the original or do you need to set them yourself?

[echo basalt]

it does return with the same fields

[tardy delta]

i was underestimating the C impl lmao

[lost matrix]

The fields are all set. But if the clone is shallow or deep is an implementation detail that might vary for different classes.

[tardy delta]

hmm

i came accross the term "shallow copy" and i forgot what it means lol

[civic mica]

Hello, I have a question does anyone have an image plugin for 1.16.5?

[lost matrix]

A deep copy would go through all fields and create a new object for each one. And it would do that recursively until it reaches primitives. So a ton of new
objects will be created in the process. A shallow copy only copies over references to already existing objects.

[granite owl]

teye gonna try that in a few

[tardy delta]

ah so a deep copy is slower

but it basically does the same as a shallow copy

[lost matrix]

No the outcome is very different. The objects might look the same but they are not.

[sterile token]

So which final code i have to use people

[sterile token]

And the radius part?

[tardy delta]

what was the issue actually?

[sterile token]

I dont know which code to choose

[tardy delta]

and what does that code do

lol i forgot

[sterile token]

Oh btw

Oh im so messed

[pine elbow]

hey does anyone know how to get the map color of a block? I Found the MapPalette class but I have no clue how to get one, and it looks deprecated. Is there a API way to get this data?

[tardy delta]

dutch lol

not you

🌝

[mighty pier]

                    if (item == null || item.getType() == Material.AIR) continue;
                    player.getWorld().dropItemNaturally(player.getLocation(), item);
                }``` it doesnt drop the items

[tardy delta]

is there something in the inventory?

[mighty pier]

yes

[pine elbow]

old username :C

[tardy delta]

still dutch

[pine elbow]

ye

[tardy delta]

[mighty pier]

EntityDamageByEntityListener, no errors

the code around it works

yes

yes

[undone axle]

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

[mighty pier]

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

cuz

i want to do the title thing

and player.respawn buggy

yes but

i want the player to respawn instantly

and player.respawn buggy

[tardy delta]

sysout the contents

before and after

and use early returns smh

do people even know that those exist

same with && thing

[mighty pier]

i have no idea what that means

[tardy delta]

prints the contents to a place

to see if its empty or not

ah lol didnt see that

[mighty pier]

omg

right

[sterile token]

So what class shoud l isue

I so confused

Because i need to calculate 2 corners knowing the center location and a radius

[mighty pier]

also how do i clear armor contents?

8 i think

[tardy delta]

i barely know what you are talking about

[mighty pier]

1.8

[sterile token]

he?

[mighty pier]

e

[smoky oak]

if i schedule two things, at different times (1 tick delay more), no matter how long the first one takes, will it finish before the second or does it run async?

[mighty pier]

ok

ty

[viral temple]

I just realised, this is the wrong channel

my bad

[tardy delta]

you are talking the whole time about corners and radius but i dont know what the actual problem is

no memes in general, they go to #help-development

[sterile token]

I dont know how to get the blocks inside the claim

[tardy delta]

all of them?

[sullen fox]

hi

[tardy delta]

that includes checking the chunks around

hello

[sullen fox]

is there any package/api i can use to get player list?

like the whole list

of players

not just number

no no

im coding a dc bot

its javascript

true

well

ty

bye

wdym

[tardy delta]

what players? from the discord or the mc server?

[sullen fox]

mc server

[tardy delta]

im confused

[sullen fox]

I want to fetch the list of the players in the mc server

[tardy delta]

whats wrong with Bukkit.getOnlinePlayers then?

[sullen fox]

Bro

I'm coding a javascript discord bot

yes

[tardy delta]

there is no way to interact with the server via javascript

[normal isle]

can someone help me compile something?

[tardy delta]

unless theres native support iirc 👉👈

[normal isle]

no

its a free one

[sterile token]

Oh lmao

[normal isle]

furniture engine

[sullen fox]

not

[normal isle]

i have no idea how to compile it

[sullen fox]

well

[tardy delta]

is it from github?

[sterile token]

im So messed up i will finally search on google how to calculate 2 corners knowing from a centered location

[normal isle]

you know how to?
