hmm, why are you using executors in kotlin?
half harness
hmm, why are you using executors in kotlin?
I used to use coroutines but after running into some issues i just decided to use executors
i don't remember what the issues were but i think it was something which coroutines not being in its own separate thread, idk
gusty glen
well, idk what you're doing, but I think Future have a getOrExceptionally or something like that
half harness
nope D:
but i think i should have googled with the term "executorservice" so i think this should work: https://stackoverflow.com/a/2248166/14105665
¯_(ツ)_/¯
gusty glen
oooh I know
you can't just throw stuff inside futures, dkim
you have to catch them and use completeExceptionally
then whoever calls get() will get ExecutionException with your exception nested iirc
half harness
you have to catch them and use `completeExceptionally`
how?
what do I run completeExceptionally on
ExecutorService#submit only has a runnable or callable parameter
gusty glen
let me hop to my ide to make an example code
ooh, and you should be using some method of CompletableFuture class which accepts an executor
gusty glen
ExecutorService#submit only has a runnable or callable parameter
hmm, could we make a test? runnable does not throw exceptions (it just "swallows" them, per say), but callable does, try to add a return "ass" below your throw statement
oh wait, I think nvm? If you figure out a way to force the usage of Callable, them you should be good, else probably what I said of using CompletableFuture will be a better option
steel heart
well afaik
You can provide an exception handler or whatever that’s called
(Through a thread factory)
Idk if it would have an impact on the future but worth a try
gusty glen
that snipped throws my "some ass" IllegalStateException nested inside a ExecutionException ```kt
fun main(args: Array<String>) {
println(someAsyncComputation().get())
}
fun someAsyncComputation(): CompletableFuture<String> {
val executor = Executors.newSingleThreadExecutor()
return CompletableFuture.supplyAsync({
throw IllegalStateException("some ass")
"ass"
}, executor)
}```
gusty glen
a method?
half harness
no i mean what does it do
gusty glen
I just created the executor inside the method for demonstration purposes only, you probably should handle them differently (like caching them) or smt
steel heart
that snipped throws my "some ass" `IllegalStateException` nested inside a `Execu...
Just use CompletableFuture::completeExceptionally then
steel heart
CompletableFuture::supplyAsync is a static factory method which begins a future with where it uses the supplier passed to compute a value through the given executor
gusty glen
yeah I know, but my example was just showing that dkim could throw exceptions inside the supplyAsync and it would work
if you have an exception ready to be returned before running the async part of your code, you can just use CompletableFuture#completeExceptionally to accomplish that feat (by creating an empty completablefuture, them completing it using that method (instance method)
steel heart
yeah I know, but my example was just showing that dkim could throw exceptions in...
Yeah cuz it wraps it with an execution exception
Anyways dkim

half harness
but the exception should have been caught

if you want to know the issue: I had another Future that ran that future but I didn't do Future#get - I just looped and checked Future#isDone

it never threw

I'm using Rider and I have console applications and I'm trying to get user input but every time when I do so I get a fucked up terminal. For example I want to read a number and when I enter a digit, it doesn't display it in the terminal. the program works well and it prints the correct number but for the user that entered the number it looks like its missing the first digit.
Also another problem I have is that backspace is displayed like a space
Here I entered 2245 then double backspace then 2444 and the output is right
is there anyway to improve that terminal?
because it annoys me so much
it is just the RUN terminal
not the normal terminal. that one looks fine. just like the one in IJ

It is one of the poisonous superstitions of our times the equal of which is not to be found even among so called primitive societies […] Vaccination is a filthy remedy.

Hmmm. So I have a string input that's made out of 0s and 1s. And you can basically replace the 1s and 0s with brackets. I need to tell if the string is a valid bracket sequence.
This would be valid sequences: 00100111, 100100
This would be invalid sequence 011001
first checks I made is for the string length to be even and then made sure that there's an even number of 0s and 1s. but how would I proceed from here? because it still doesnt count stuff like this one 0101 for example.
prisma wave
why is 011001 invalid?
oh, because there are 2 )'s?
ok
easy
use a stack
actually you dont even need a stack

yo how can I get the name of an entity by String, im trying an dying inside, getName is also deprecated.
This is what i got so far
@EventHandler public void onPlayerHit(EntityDamageByEntityEvent e){ String ent = e.getEntity().getType().getName(); DEPRECATED e.getDamager().sendMessage(ent); TRYING TO FIGURE OUT WHAT getType() RETURNS boolean check = this.getConfig().getBoolean("entities."+ent+".check"); if (e.getDamager().getType() == EntityType.PLAYER && e.getEntity().equals(this.getConfig().getString("entities."+ent)) && check) { e.setCancelled(true); e.getDamager().sendMessage(Objects.requireNonNull(this.getConfig().getString("entities." + ent + ".message"))); } } }
Config
entities: villager: check: false message: "Non puoi uccidermi, smetti di colpirmi >("
I want the users to set as much entities they want from the config so I check in there with e.getEntity().equals(this.getConfig().getString("entities."+ent)) but getType does not return a string so I added getName

Hey, so I've been messing around with fake blocks using spigots sendBlockChange and I'm looking for a way to detect when a player clicks these fake blocks.
I've been able to disable right clicks to prevent them from going away but I need to do this only for the select blocks. Just really need the cords and maybe material. Is that possible with what I have? Just looking to be pointed in the right direction.
getServer().getPluginManager().registerEvents(this, this);
protocolManager = ProtocolLibrary.getProtocolManager();
protocolManager.addPacketListener(
new PacketAdapter(this, ListenerPriority.NORMAL,
PacketType.Play.Client.USE_ITEM) {
public void onPacketReceiving(PacketEvent event) {
Player p = event.getPlayer();
if (event.getPacketType() == PacketType.Play.Client.USE_ITEM) {
event.setCancelled(true);
i++;
p.sendMessage("Use Item event fired! " + i);
}
}
});

i started working on a plugin that was a replacement for the vanilla enchant table and now im trying to make a box system that stores all the items that could be lost from custom inventories cause i didnt want to just drop it on the floor
and then ended up rewriting half of it and now i have a project that wouldnt do anything cause i havent got it working yet
also i tried to organize my code and ended up making a bunch of little classes that do small tasks and just interwiring them together and now im stumped and bored and going back to watch youtube about game design
i have no clue how people come out of it with a viable project
quite happy that im not the only one
i might just scrap the box since its more trouble then its worth and ill come back to it another time

coding related stuff
i still don't get why #development isn't named #coding 😖
brittle leaf
so would #minecraft be the place to talk about server development?
half harness
either that or #placeholder-api, #general-plugins, or #general-plugins-2
brittle leaf
its just cause i was in the planning stages of a server i wanted to make and those seem more plugin help sorta thing instead of actual design talk places
half harness
hmm
yea i think u can ask in #minecraft
although most of the active members here code rather than manage a server
brittle leaf
i mainly wanted to brainstorm a couple ideas and make some sort of prototype just to see if i could do it rather then release publicly
because public servers are a bag of snakes that i dont want to get into really
i just wanna code some stuff and see where it goes
and also wanna look at nms and see what packets i can modify

I mean wiki.vg is that, a wiki, info about the current minecraft "spec"
btw does a mc developer write that?
or does someone decompile mc
obtuse gale
packet manipulation has nothing to do with the packet stream spec (so neither with wiki.vg), and how you achieve that also depends on the platform you use, it's not the same for bukkit than for fabric

it's all reversed engineered

Hi there, I have several questions about loading/storing datas on database:
My plugin saves datas for each players connected on the server every 5 minutes from the player connexion but:
-
Isn't it better to save the data of all players connected at the exact same time ?
-
In that case, shall I keep the desync data save?
winter iron
I would save at 5 minute intervals based on server time rather than player connection time
it just makes coding it a bit simpler too
You can do batch updates then too
reef maple
That means I should save all players simultaneously ?
oak coyote
If it’s async yeah
You will just idle out that separate thread for a bit but otherwise no issues really ever occur
Make sure to make your onDisable a main thread save
reef maple
Ok I use async by default, I should add it sync on onDisable
prisma wave
Yes
You need it to block onDisable
CompletableFutures are nice here
You can have it async by default or force it to block when you need
reef maple

is there no actual way to modify a final field past java 12 without adding extra commandline parameters?
forest pecan
is there no actual way to modify a final field past java 12 without adding extra...
if it isnt static, then no
it gets inlined iirc
steel heart
trying to replace the spawner field specifically
That should be possible
I don’t know if reflectively setting the field’s value would overwrite it, but if not then I guess good ol’ Unsafe
tranquil crane
I'm currently trying unsafe to see, using reflection was a no-go
I believe it's only static final fields that get inlined
forest pecan
Yeah nvm my life is a like lmfao. i just realized that is an anonymous class
tranquil crane
yeah it would be real hard for that class to get inlined lol
forest pecan
i originally thought of unsafe but i didnt know if it'd work
tranquil crane
well we're about to find out
tranquil crane
I will yeah
hm I couldn't even access Unsafe
java.lang.IllegalAccessError: class dev.rosewood.rosestacker.nms.v1_17_R1.NMSHandlerImpl (in unnamed module @0x3ee60427) cannot access class jdk.internal.misc.Unsafe (in module java.base) because module java.base does not export jdk.internal.misc to unnamed module @0x3ee60427
tranquil crane
Field unsafeField = Unsafe.class.getDeclaredField("theUnsafe");
unsafeField.setAccessible(true);
unsafe = (Unsafe) unsafeField.get(null);
It doesn't look like it was the reflection that failed but simply trying to use the Unsafe class
that was with the jdk.internal.misc.Unsafe class, I'll try the sun.misc.Unsafe one and see if that's any different
forest pecan
Yeah try the other one
tranquil crane
oh my god it worked
forest pecan
Yeah i read a post online regarding it
cause one is exposed
but the jdk internal one isnt

yea i just wasnt clear what the final var was
tranquil crane
Field field_SpawnerBlockEntity_spawner = ReflectionUtils.getFieldByPositionAndType(SpawnerBlockEntity.class, 0, BaseSpawner.class);
Field unsafeField = Unsafe.class.getDeclaredField("theUnsafe");
unsafeField.setAccessible(true);
Unsafe unsafe = (Unsafe) unsafeField.get(null);
long offset = unsafe.objectFieldOffset(field_SpawnerBlockEntity_spawner);
unsafe.putObject(spawnerBlockEntity, offset, new StackedSpawnerTileImpl(stackedSpawner));
|| naming conventions 🙃 ||
tranquil crane
I purposely name my reflection variables terribly like that so I can actually read them
forest pecan
and also just cache unsafe ig in general if u havent done it
tranquil crane
yeah it is cached I just put it all together there for you
forest pecan
mhm thx
tranquil crane
complain about my reflection variable names all you want lmao
half harness
💀
tranquil crane
that reflectionutils thing is because I use mojang mappings so the fields end up having different names during runtime
can't be bothered trying to switch between the two so I just look up fields based on type and position
ocean quartz
Huh interesting someone forked my lib and committed "changed reflection naming to be more readable" and they also named the variables like that 
ocean quartz
A dude called "evernife"
tranquil crane
that is kinda similar
tranquil crane
mine goes reflectionType_className_fieldName
reflectionType being field/method
I do it purely for readability even though I know it goes against conventions
anyway glad I can do this with unsafe at least for java 16, going to hope 17 also works since 1.18 is using java 17 confirmed now

I believe it's only static final fields that get inlined
final instance fields with a primitive data type inc String would also get inlined iirc, where the value of the field is known at compile time ofc.
