It's hard to tell what's going on with so little context. Is any code running asynchronously/on new threads? Where are things added to/removed from the list?
glass mason
just when someone sends a message
only usage
as I said before ".......but on my computer nothing weird happens.."
this should work
lyric gyro
Is any code running asynchronously/on new threads?
lyric gyro
can you show more?
glass mason
yep
this code is so simple and doesn't have much code
I still think this is occurring due to replit issue
becuase this code run perfectly smooth on my computer
and the jar on my computer is the same jar on replit
I even recompiled it and repackage it
just to be sure
lyric gyro
Okay so you are creating new threads (readThread extends Thread (might want to rename the class itself to ReadThread though)), Server.messageHistory (it's a regular ArrayList which is not thread safe) is being modified from the whichever many client connection threads you create
Concurrency is a bitch, anything can happen
glass mason
can you suggest a solution that could work?
pure crater
You can make your list thread safe by using a concurrent implementation
So you won’t run into that issue
glass mason
what do you mean by saying concurrent implementation? I'm a begginer in java
winged pebble
Thread safe
glass mason
Thread safe
I know, the question is how to use concurrent implementation?
lyric gyro
this could be easy to fix without overengineering a solution but it might be a band-aid patch on the long run
flat anchor
lyric gyro
eeeck
dusky harness
I know, the question is how to use concurrent implementation?
you can use Collections.synchronizedList
not a concurrent list
but it'll work
lyric gyro
no it won't
lyric gyro
That only allows single-thread access to each method (adds synchronized to every method), but once you get the iterator you are outside of the sync list itself and you're still gonna modify the list as you iterate it
dusky harness
oh
dusky harness
ConcurrentLinkedDeque
does the iterator in this work? or does it have the same issue
lyric gyro
They could use a CopyOnWriteArrayList instead of an ArrayList but that's gonna be funny for memory usage on the long run - or use some sort of (thread safe) queue to offer/pull messages between threads rather than iterating
glass mason
so what is the best way?
for short term
I dont really care much about this java application this is mainly for testing
dusky harness
so what is the best way?
well for a "list" I think you can use ConcurrentLinkedDeque
I think
lyric gyro
uh i don't think a set is fit for this
dusky harness
oh wait which one
lyric gyro
any
lyric gyro
if I send two messages with the same contents then that's gonna be a no-go lol
glass mason
it's on server class
glass mason
well for a "list" I think you can use `ConcurrentLinkedDeque`
so is this the best way for this particular needs?
lyric gyro
Quickest and dirtiest solution? Use a Collections.synchronizedList(new ArrayList) for messageHistory and use an indexed for loop (for (int i = 0; i < messages.size(); ++i)) with List#get(int index) instead of enhanced for loop (for (String message : messages))
But this is smelly lmao
dusky harness
so is this the best way for this particular needs?
for what I can see in the code, it'll work afaik, but note that you can't do get(index) on it
although technically you can iterate through it and get the element that way 🥲
🥲
dusky harness
Quickest and dirtiest solution? Use a `Collections.synchronizedList(new ArrayLis...
orrr you can do this
¯_(ツ)_/¯
lyric gyro
Concurrency is nasty, and doing it well isn't easy
glass mason

collections from java.util?
lyric gyro
yee
glass mason
are you sure?
lyric gyro
uh, yes? 
why
pure crater
I mean, it’s like the only import option lol
glass mason
i have an image to send
but i don't have the preivleges to send it'
maybe imgur will help
glass mason
pure crater
Lol
lyric gyro
err could you show the whole line?
lyric gyro
Also this is the solution to iterating a synchronizedList safely, I never read that lmao
CC @dusky harness
dusky harness
Also this is the solution to iterating a `synchronizedList` safely, I never read...
oh
makes sense 🥲
glass mason
oh nevermind
lyric gyro
so yeah you could do that with a synchronizedList instead of doing the indexed for loop
both solutions should work
lyric gyro
the actual class is implementation detail, you'd just use a List<String>
like List<String> messageHistory = Collections.synchronizedList(new ArrayList<>());
and then when iterating
synchronized (messageHistory) {
for (String message : messageHistory) {
// ...
}
}
Ok it fixed the error and now it doesn't show up in the console
but I still getting null in the client
please note that on my local machine it works fine
but on replit...
fine I dont really care about that server on replit, most important is that it actually works on my local machine perfectly fine
Another question - can I place the JDK folder or JRE in the project folder and run jdk/bin/javaw.exe -jar asdsd.jar and it will run on any machine?
wintry grove
I believe you can
thats how minecraft bundles the jre for example
now its my time to ask
can you spawn fireworks with different angles?
like I want to spawn one that goes to the right
and another that goes to the left
can you do so?
and how?

Hey folks I have a pretty hefty set of questions for yall
I'm trying to create a new api to be used in place of the bukkit scheduler. However, I'm using ProjectReactor, to ensure the scheduled tasks are all reactive and non blocking. My first question is, how would I get the service in question able to be executed on a new thread?
My second question is: how can I make a service execute repeatedly, and how can I delay it?
Third and final question: would the actions in question be considered asynchronous as they're operating on parallel threads and not on the main thread?

edgy lintel
private final Map<String, PlantTicker> plants = new ConcurrentHashMap<>();
sth to do with keyset prolly
See here
||keySet: The view's iterator is a "weakly consistent" iterator that will never throw ConcurrentModificationException, and guarantees to traverse elements as they existed upon construction of the iterator, and may (but is not guaranteed to) reflect any modifications subsequent to construction||
It’s not guaranteed to reflect any modifications made
Try doing thread.sleep maybe for even like 3 ms and see if the changes is posted
sterile hinge
that won't change anything as
and guarantees to traverse elements as they existed upon construction of the iterator
having random sleeps in your code isn't how you solve threading issues, but this isn't a threading issue anyways
edgy lintel
having random sleeps in your code isn't how you solve threading issues, but this...
Retrieval operations (including get) generally do not block, so may overlap with update operations (including put and remove).
This statement implies that put is non blocking too and is async to be overlapping with another async function
So the get function may have preceded set function
And the other problem may be that all sync operations are done before async operations
So this can be a thread problem
And indeed sleep may not solve this issue but at least it will test if this is indeed the issue
sterile hinge
no
threading issues can only appear if multiple threads are involved
and "non blocking" is often confused, because the method actually does not return until it did its work.
edgy lintel
Depend on your definition of threading issues
The set operations create a new thread apart from the main thread,which is exactly the definition of non blocking
So it’s effects have to be delayed after all synchronous operations finish
sterile hinge
The set operations create a new thread apart from the main thread,which is exact...
that's just wrong
edgy lintel
What do you mean
If an operation is non blocking it means that the operation is async
I’m talking about the operation not the function
sterile hinge
please read the documentation instead of spreading false information
CHM does not create any threads at any point
retrieval operations don't block, but that still doesn't mean those methods run anything async
merry knoll
threading issues can only appear if multiple threads are involved
this, chm does not do anything async by itself
edgy lintel
My mistakes
merry knoll
unless the person is calling from another thread (even then should be no issue as the retrieval and put is on the same thread)
edgy lintel
Should be synchronisation issues
Or locking sequence or sth
But delaying get for a few ms certainly would help
sterile hinge
If the code is as shown, there is only one thread involved
merry knoll
If the code is as shown, there is only one thread involved
even if there were multiple, that method would still be used by only one thread
so that should not cause an issue
sterile hinge
Yeah
edgy lintel
Yes my mistakes
merry knoll
i just tested, putting and pulling from a concurrent hashmap works fine
so my bet is there is somehow an issue maybe with the objects that they are putting in
but they didnt say anything about npe either so
edgy lintel
I mean it can be inherent thread design problem
sterile hinge
It’s probably just a weird toString method lol
edgy lintel
Like the synchronise or read and write block problem
merry knoll
It’s probably just a weird toString method lol
most likely
merry knoll
I mean it can be inherent thread design problem
whole point of chm is that you dont run into those issues
quite sure its safe up to? 16?? operations at the same time

it will remove the entity from the world

but it's worded like that because it won't necessarily be removed in that same tick afaik

no, it is worded like that because md sucks as writing documentation, wdym

oh, understood, thanks.
worn jasper
Uhm quick question, any way to deserialize a text with MiniMessage and return a string instead of Component?
tried toString, but kinda returns this
(Trying to set the name of an armorstand btw, which doesn't accept components)
icy shadow
you have to serialize the component in some way
if you want it in § form then use LegacyComponentSerializer
lyric gyro
no, it is worded like that because md sucks as writing documentation, wdym
that function has existed loooong before md, lol
dense drift
ah ah

I serialize, the deserialized component?
icy shadow
pretty much

You can either use what BM suggested, or try to set the name using reflections, that should work

(Trying to set the name of an armorstand btw, which doesn't accept components)
Surely it does? Like any other entity?
lyric gyro
lyric gyro
lol
worn jasper
uhm another quick question, anyways to fix this "shadow glitch"?
like, since the armorstand is inside the block, it displays the name like it's "suffocated" or well, "inside a block"
lyric gyro
setMarker(true)
worn jasper
okay, thx
lyric gyro
that will get rid of the hitbox altogether so you need to place the armour stand where you actually want it to be
i.e. above the thing rather than trickily below
lyric gyro
yea
worn jasper
k thx
Oh also, entities, specifically armorstands, can't be removed async right?
Does that also apply to spawn?
lyric gyro
it applies to every entity
dusky harness
Uhm, any ideas on how I can serialize an armorstand?
make a data class with location, etc and serialize that instead
I don't think you can serialize the entity itself
¯_(ツ)_/¯
lyric gyro
welll
you "can", you just are very very very much not supposed to do it
usually you save data that refers to the entity, like the UUID
worn jasper
Well, actually, no need to serialize it, found another way, but thanks. Also, any way to prevent like, the armorstand being visible for a mili second?
worn jasper
like when I spawn the armorstand
I can see it for a millisecond
it doesn't go invisible directly

use the spawn method that takes a Consumer, and in that lambda you can "configure" the entity before it's added to the world

maybe 0.2? or something
works?

basically doing this:

why dont you get the entity by its id or something

Would the DeluxeMenu developers be interested in changing the EventPriority for its PlayerCommandPreprocessEvent listener (in PlayerListener) from LOWEST to LOW? I maintain a plugin for creating Bedrock Edition Forms and I provide a way of intercepting commands so that server owners can instead show forms to bedrock edition players. The problem is that DM uses the LOWEST priority so I cannot modify the event before DM does its thing. It would be nice if DM also ignored the event if it was cancelled.
The workaround for this is setting the DM menu to register_command: true but that isn't really a solution for users that use DM to intercept commands from other plugins. Or just not using open_command.

For some reason, I have been having trouble using SplittableRandom. I first tried RandomGenerator.getDefault(), however, I would get an error saying that No implementation of the random number generator algorithm "L32X64MixRandom" is available. So then I tried RandomGenerator.SplittableGenerator.of("L32X64MixRandom") in order to try to specify the implementation to use. However, I still get the same exact error.
What is weird is that when clicking on the SplittableRandom interface and clicking on View Implementations, I can see the source code for the L32X64MixRandom class. However, when I try to import the class, Intellij cannot identify the class.
So after some research it turns out some JDK's don't actually have the implementations?

Hi, so, right now I have this method, which well, as the name says, is supposed to delete a hologram with the specified uuid in the location's chunk:
The issue I am having, is that, whenever I unload the chunks, and wait a bit, and load them again, it seems like, this method can't find the hologram??
Do the armorstands change the UUID or something?
mental cypress
Possibly!
worn jasper
Hmm, will test it then, thanks lol
quite a stupid mistake
still get sometimes confused when I should use == and when I should use .equals
since both can compare objects
dusty frost
since both can compare objects
== compares referential equality for objects
so if they are not referencing the exact same object, it will not be true
.equals() methods are user-defined, which, especially in this case with objects being loaded and unloaded by the garbage collector, is what you want
when you're using enums (like you are above) or numbers, you want to use == as you can't use .equals

Well you can't create multi lined holograms with the display name of 1 armorstand. You use multiple named armorstands with an offset of the ylevel.
Also with holograms I know it's a bit more advanced but I recommend looking into nms and using packets. Otherwise your gonna be running things on the main thread which won't be to beneficial in terms of performance.

errant kraken
which one would be better performance-wise for checking something every tick, relative to every player: using PlayerMoveEvent or using a repeating scheduler?
dusty frost
well it kinda depends on what you're doing
are you checking something every time a player moves? because there can be a ton of those every tick
or are you checking for like one thing every tick?
errant kraken
are you checking something every time a player moves? because there can be a ton...
yeah, I am checking if they are looking at another player, then display a bossbar
dusty frost
yeah so that wouldn't really be a very good use case for PlayerMoveEvent, as they would have to move to see the boss bar?
errant kraken
well yeah, and if they are no longer looking, the bossbar disappears
dusty frost
yeah but they can rotate their camera without PlayerMoveEvent firing
I mean either way it's not going to be great for performance, but it doesn't really make sense tying pitch/yaw to x/y/z movement
errant kraken
what if they move without rotating their head and a player pops in their view?
dusty frost
then the every tick check will get it?
what if they rotate their head without moving and a player pops into view?
PlayerMoveEvent won't show them a bossbar lmao
errant kraken
why not? the x,y,z will change, but not the yaw and pitch, PlayerMoveEvent fires when either of these change
dusty frost
PlayerMoveEvent fires on pitch/yaw? I thought it was only x/y/z changes
errant kraken
yeah
broken elbow
PlayerMoveEvent fires on pitch/yaw? I thought it was only x/y/z changes
yeah
it does
dusty frost
If so, then it doesn't really matter, though depending on how events are handled, it'll probably be better to listen to that event (if it only can happen once per tick per player)
dusty frost
weird
i would've thought there'd be separate x/y/z movement and pitch/yaw move events
errant kraken
If so, then it doesn't really matter, though depending on how events are handled...
I thought about that, the event can eventually stop firing when no one moves, but the scheduler will check forever
dusty frost
well i doubt that'll really be happening often, but moreso just less players if the events are capped to once per tick per player
whereas the scheduler will iterate over every player every tick no matter what
though to be fair, players can also move without you moving
so if someone walks into your view, the bossbar wouldn't show until you moved
broken elbow
yeah. unless you do the double check in the playermoveevent. which seems not that good.
errant kraken
if there's not that big of a difference, then I guess a scheduler seems to be the choice

I really don't think you should be using 1.9
It's a bad decision to make since versions like that are at this point hella unstable and prone to loads of exploits
You can do much, MUCH cooler stuff with the latest version when it comes to resourcepacks, that doesn't have to involve finnicky stuff like item damage
Development wise you're also going to be stuck with a really old version of the API that has nowhere near as many improvements/features as the current one
edgy lintel
i took processing power into consideration
mmorpg takes a lot of mechanics based calculations so i just fear that 1.19 will be too much of a burden for servers to accomodate large amount of players
and about resourcepacks im too noob at that to make good packs lol

I think no matter how motivated you are, you're not gonna be able to remake an entire server system that a bunch of developers collaborated on to house over 60k players concurrently.

Hypixel does not do a lot of chunk generation lmao

Money motivated them, money
edgy lintel
what makes them earn more money with a custom piece of server software?
it just adds more work instead of making more gamemodes
dusty frost
it can run way lighter
high edge
Because people play and spend money on the server?
dusty frost
turns out that the Notchian server, not the most well optimized lmao

Well no shit sherlock

Nah they just have stupid big numbers because of all the publicity, so they had to keep up with the demand somehow. It's split into thousands of smaller server instances for each gamemode to be able to keep up.

like, you wouldn't want Hypixel's server software for your latest SMP server
but it's really good for quick-starting minigame servers

uh well, not exactly
it's more likely they're using something like Docker and k8s
would recommend their dev blogs if you're interested, they go into a lot of detail about some cool stuff, like making a custom world file format for their housing servers

wow this post has been really harsh on him
he was like a god to me back then
i used to watch his videos non stop while chugging cola in mc donalds and i just blindly followed his code after watching his whole video and find joy in manipulating basic events
someone even got into uni and landed a dev job because of him.
The post is mainly about deprecation and bad conventions. Honestly those part about deprecated methods and bad naming conventions did not matter to me at all. I corrected all of them later on when partly seriously about learning java as a whole.
And that part about his lack of knowledge about java. Honestly I have already forgotten about that to this day because i wasnt learning java from him but i was learning how to code in bukkit. Any style did not matter to me at that time and as long as it works and as long as i can learn the proper methods to do stuffs i would be happy.
For me this is way too harsh for my past personal god like honestly he doesnt deserve criticism like that being a pioneer in bukkit tutorials
high edge
Everyone deserves criticism, best way to improve, when people aren't allowed to critisize you get shit like the current events happening in the world
edgy lintel
honestly constructive criticism yes but all the mockings and sarcasms no

No

should be event#getWhoClicked()
dusty frost
well you can get the entity and use Player#getTargetEntity()

New to making particle effects and this aura does not feel quite right
In fact its quite disgusting (just the shape not colour that matters
is there any cooler way to make particles

it is what it is maybe you may want to change the particle type that is how that one looks like

edgy lintel
im just looking to make someting like this
but i end up like this
colour is certainly something to change
but the shape and stuffs for now i am resort to using formulas
edgy lintel
maybe i should use something like custom model data and make an effect sticker or sth?
nimble vale
yes and also there will be lots of particles and some clients may struggle to show them continuously

if changing particle textures possible you can actually make something with it
edgy lintel
that would be lit
but on the other hand I actually thought about it but i want people to be able to customize their aura and stuffs so i didnt want to use texture
but if textures make it look better then imma go for it
is there such thing in mc tho
like custom model data
nimble vale
yeah think about it more before you actually try to implement and also i believe that you can still make auras customizable with custom textures
just show different custom model data depends on each players settings
edgy lintel
i mean like i want people to customize particle physics or make their own aura shape or sth
but for now its too overwhelming for me
edgy lintel
yo that looks real nice
i can change the colour using spawnParticle method with that right
that would be super cool thx bro
oh i actually cant
nimble vale
you can only change the color for redstone dust particle
edgy lintel
still pretty nice
gonna try and use that to model super saiyan blue
thx so much
nimble vale

still not sure I understand your question honestly

index = the current char of the word?

yes
dusty frost
yes

oh wow thats really nice

you don't need the index, since you already have the character

thats amazing

java has that too lmao

most languages do lol

C moment

not C 😭
dusty frost
iterables are a thing in like, basically every language I can think of that is used in the modern day besides C lol
dusty frost
oh no not the Allman brackets
tacit quail
what kotlin does in one line ;-;
dusty frost
this is what i have to do in C to get that
and that is why C is old and unsafe lmao
tacit quail
Im kind of liking this new kotlin thingy
dusty frost
oh no lmao
tacit quail
uh you could just do `return strlen(text)` lmao
no im using the strlen for somthing else
dusty frost
i have a feeling Strings just have a property for length anyways
tacit quail
im returning a different variable
icy shadow
i have a feeling Strings just have a property for length anyways
not in C they dont
dusty frost
oh I thought you meant in Kotlin lol
icy shadow
the C string type is null terminated rather than storing a length
merry knoll
strlen or smt in c i think
merry knoll
its a method though not a property
dusty frost
it's a property in Java for some reason lmao
icy shadow
old java code is not very consistent
icy shadow
kotlin bad
merry knoll
kotlin gud
icy shadow
wrong
dusty frost
I mean it kinda should be a property
icy shadow
it doesnt matter really
merry knoll
yeah, i prefer property too
icy shadow
purely stylistic
dusty frost
Java is just weird because it has special syntax for arrays for some reaosn
icy shadow
what
sterile hinge
it's a property in Java for some reason lmao
?
dusty frost
it doesnt matter really
I mean it makes more sense in the object oriented sense
icy shadow
what on earth has that got to do with strings

oh yeah I was thinking of arrays sorry
icy shadow
I mean it makes more sense in the object oriented sense
eh, for things like mutable collections a method arguably makes more sense as property might imply it's a constant
but im nitpicking here
dusty frost
eh, for things like mutable collections a method arguably makes more sense as pr...
how does a property imply it's a constant
the whole point of OOP is that properties are state and they change
if anything it should explicitly not be a function, because that function is just a getter and it does nothing special
icy shadow
how does a property imply it's a constant
in kotlin if you have val size: Int theres nothing in the code saying that might change
obviously you know from context
but in terms of self-describing code it's not ideal
dusty frost
that's why you make it a var???
dusty frost
that's cause Collection is immutable
MutableCollection is the interface for mutability where the size actually can change
icy shadow
i know
but there's nothing saying that size is actually mutable sometimes
you just have to know it from the context
dusty frost
I mean it really shouldn't be if it can change
grizzled wagon
does anyone know the answer to my question in #general-plugins 😅
icy shadow
I mean it really shouldn't be if it can change
what
"it shouldnt be mutable if it can change"
?
dusty frost
it shouldn't be val if it can change
icy shadow
that is entirely my point
dusty frost
that is entirely my point
dusty frost
Kotlin bad, confirmed
icy shadow
kotlin bad yes
