can't you build it yourself?

In the beginning of every task
noble lantern
Well i create a new Logger instance inside my task
so Logsl4j should pick up the thread
plus
its bricking the request handler
ashen quest
its not
noble lantern
so if i Thread.sleep() it wont use a new thread
it wants to run it on 115 still
let me try with only availableProcessorCore size
ivory sleet
noble lantern
Doing that makes it block on thread 19
ivory sleet
Try to print the thread in the beginning
noble lantern
kk
takes time to debug because thats the core lib
so i have to edit compile then import into gradle

current async thread = inside runAsync
server thread is outside of it
which is fine that thread can stay the same bc it needs to
i rly wonder if calling join() on CompletableFuture is messing with it somehow
but without it the threads never completed and hung on non complete status
maybe its broken locally
lemme upload to prod

your just sending fake blocks to the player
round eagle
specifically its a minecraft server. the response determines the status of the server eg. String online = true/false;. should it be safe?
ivory sleet
It starts at 115?
noble lantern
It starts at 115?
When i was running at 96 threads it did
un using Runtime.availableProcessors now
on prod the requests always execute on worker 3
ivory sleet
Hmm
ivory sleet
Ima write a test
noble lantern
Does calling join() on futures possibly have something to do with it?
ivory sleet
No
tardy delta
poor string class
ivory sleet
Wouldnt day that
noble lantern
public static void runAsync(Runnable runnable, Executor executor) {
CompletableFuture.runAsync(runnable, executor).join();
}
This is the runAsync code if needed
i just pass the executer code you showed me a bit ago
ivory sleet
Wair
This kind of defeats the point
Wouldnt it be better to just run it as is
join blocks
Its like await in javascript
ivory sleet
Why do u use a thread pool in the first place
noble lantern
Well its what you suggested
I was just using the normal runAsync() without the pool beforehand
but i would assume it would stop forking new threads after x amount of them
and then start blocking
well no futures queue dont they

That is awaiting

its just weird bc without wait earlier
i bricked my container
it was weird
the logger logged the threac count in increments of 1
then went to a high number, restarted back to 1
did it a few times then bricked at 60mb ram and 2% cpu
was rly weird....
ill try it again rn with new executor

need to do more testing if its bricks again tho
Thanks Conclure!

im honestly suprised no mem leaks in all of this sytem
i was spamming it earlier with 96 threads and it barely hit 80mb ram

oh wtf
ivory sleet
Its just the amount of active threads the pool should try to maintain
noble lantern
thought it was limited to the long provided
is there an option to set max?
well
eh
i assume it would start blocking at that point

Yeah

not really performance difference *8 and *64 tbf

Yeah
noble lantern
just slightly more ram

You need to kick players on the main thread
not async
you should be able to synchronize and object to lock and then call that method sync, or just remove that runnable all together
and handle socket connections in a diff runnable
round eagle
You need to kick players on the main thread
how do i pass a boolean var from there to the main thread?
round eagle
and handle socket connections in a diff runnable
apologies. im not very good with java
noble lantern
Not sure if you can do this in Bukkit but IIRC you can pass a sync task inside the async one and it will run back to main thread
But typically you use synchronized to shove onto the main thread providing a object lock (Hopefullly explained that right)
Store the boolean as AtomicBoolean on the main thread not a standard boolean
hybrid spoke
or just a CF and accept the boolean
noble lantern
runTaskAsync(() -> runtask(())); works?

runTaskAsync(() -> runtask(())); works?
this code
Your running an async task with BukkitRunable
You can call a sync task insde of that current async task
sec
This code block here (And any code that interacts with bukkit/bungeecord) needs to be run in sync
round eagle
You can call a sync task insde of that current async task

so you can just do the same thing you did with the async task, but use runTask
instead of runTaskAsynchronusly

Hello ! i'm a little sad that i need to ask but i need help, i need to add potion effects to player when they equip armor and remove the potion effects when they remove it. BUT when the player doesn't have anything equiped and we throw potion on it the effect is removed, so idk what to do
eternal oxide
what kind of effect?
plucky cliff
strength
eternal oxide
Put Attribute modifiers on the Armor piece
plucky cliff
For speed too ?
eternal oxide

so you can just do the same thing you did with the async task, but use runTask
it is now freezing the whole server for some reason

You'd need to do it a bit like the enum class does it

bruh ive been on this for hours now
deaths:
'1':

how do i parse through each of them and return each value as a PotionEffect

i just gave up on that ngl
eternal oxide
deaths.1 is a List, each element of that list is an Object which is a Map<?,?>
tardy delta
hmm good
ornate mantle
`deaths.1` is a List, each element of that list is an Object which is a Map<?,?>
heres the thing im dumb as shit
lemme show you the code im using
ornate mantle
potionEffectList = new ArrayList<>();
this.config.getList("deaths." + deathNumero).forEach(__effectList -> {
LinkedHashMap effectList = (LinkedHashMap) __effectList;
for (Object o : effectList.keySet()){
potionEffectList.add(
new PotionEffect(
PotionEffectType.getByName((String) effectList.get(o + "effect")),
Integer.MAX_VALUE,
(Integer) effectList.get(o + "multiplier")
)
);
}
});
return potionEffectList;```tf
ornate mantle
`deaths.1` is a List, each element of that list is an Object which is a Map<?,?>
tf does ? mean
is it like an undefined datatype
tardy delta
for (String deathNumberOrSmth : config.getSection("deaths")) {
List<?> list = config.getList("deaths." + deathNumberOrSmth);
String effect = ...
}```i lost it at the list part lolits a method
deathnumero is a value given when calling the method
public List<PotionEffect> getEffectsFor(int deathNumero){
tardy delta
then dont iterate
idk what type the list is cuz its some weird structure i have to agree
ornate mantle
some guy here gave me that format
eternal oxide
this bit os wrong new PotionEffect( PotionEffectType.getByName((String) effectList.get(o + "effect")), Integer.MAX_VALUE, (Integer) effectList.get(o + "multiplier")
o is your KeySet element, so its either effect or multiplier
which is not how you want to do it
effectList is is actually a Map not a list. Carefull with naming
eternal oxide
so effectList.get("effect") will get you the effect
and best to drop the __ on variables. Its not normal for java

Hello guys i'm back again 🙂 i need help to add and remove attribute modifier when entering water the event i did (and it doesn't give attribute to my boots ) :
@EventHandler
public void inWater(PlayerMoveEvent e){
ItemStack waterBoots = new ItemStack(WaterArmor.waterBoots());
Player p = e.getPlayer();
Location loc = p.getLocation().subtract(0.0,1.0,0.0);
if(p.getLocation(loc).getBlock().getType() == Material.WATER){
ItemMeta changeMetaWB = waterBoots.getItemMeta();
changeMetaWB.addAttributeModifier(Attribute.GENERIC_ATTACK_DAMAGE, new AttributeModifier("SpeedEffect", 1, AttributeModifier.Operation.ADD_NUMBER));
waterBoots.setItemMeta(changeMetaWB);
}
}
Do you set the boots to the player? I don't see that here just creating a pair of boots and setting it's attribute?
plucky cliff
i have the boots on me

Okay? But how are they going to get the meta from your method here?
You create a new itemstack and set it's attribute and then that's it

plucky cliff
tell me if i'm wrong but, i need to check if the player have the boots and then if it have the boots get the player inventory and boots slot to add attribute to the boots
vocal cloud
Bingo

Anyone know if i can find some old mappings? Im not sure what this is from 1.16.4 to 1.18.2

However, you might want to be careful cause if it gets the attribute and then they leave the water with them off they keep the effect. Make sure to add a remove as well.
plucky cliff
Yes ! I'm not forgetting about that !

I have a flyingFeather here for when player right click it they can fly, but it also drains their mana, there is a problem I am having where if they disable their flying, and re-enable it, the runnable runs twice, and drains double the amount then what it should be. this goes the same for the combat log when they turn flying on again.
any ideas on how to make the runnable only go once if they decide to fly again?

Check if it has it to begin with. Use PDC or something.
plucky cliff
Check if it has it to begin with. Use PDC or something.
i did that :
if(p.getLocation(loc).getBlock().getType() == Material.WATER && !(p.getInventory().getBoots().getItemMeta().hasAttributeModifiers())){
ItemMeta changeMetaWB = p.getInventory().getBoots().getItemMeta();
changeMetaWB.addAttributeModifier(Attribute.GENERIC_MOVEMENT_SPEED, new AttributeModifier("SpeedEffect", 0.2, AttributeModifier.Operation.ADD_NUMBER));
p.getInventory().getBoots().setItemMeta(changeMetaWB);
}
but now i have another problem it give the attribute 6 times

i have a plugin simulating walking by setting the npc's velocity every tick, but i noticed that its interfering with the npc's knockback
how would i go about fixing this problem while still being able to make the npc walk
this is my code atm (sorry its kotlin)
private var motionX: Double
get() = player.velocity.x
set(value) {
player.velocity = player.velocity.setX(value)
}
private var motionY: Double
get() = player.velocity.y
set(value) {
player.velocity = player.velocity.setY(value)
}
private var motionZ: Double
get() = player.velocity.z
set(value) {
player.velocity = player.velocity.setZ(value)
}

as i already said, i dont have experience with that, but it's obvious, that since u set velocity every tick, then the velocity recieved from knockback is discarded, im not sure whether u can fix it without using path finding api. if u want npc to just walk straight u can as well make it to walk to the location of the block in front of him every n ticks ig

attributes are cumulative. if you add it more than once it will add up

plucky cliff
Add
eternal oxide
0.2 is quite a lot to add. Its a quater block per tick
plucky cliff
How to get the speed of speed 1 potion ?
eternal oxide
if you use MULTIPLY_SCALAR_1 and set 0.1 it will increase your speed by 10%
so to match a potion use MULTIPLY_SCALAR_1 and 0.2
eternal oxide
yes, add is a fixed speed increase
scalar is a percentage increase
you don;t sort them, you add them as scores
plucky cliff
yes, add is a fixed speed increase
So to do it with strength it's GENERIC_ATTACK_DAMAGE ?
eternal oxide
yes

For the ```java
NamespacedKey key = new NamespacedKey(pluginInstance, "our-custom-key");
Hmm, basically you might wanna do stuff like
NamespacedKey itemIdentifier = new NamespacedKey(pluginInstance, "customItemIdentifier");
or smth
if you can about identifying different items down the line
that way a) each item can have a unique string id under that key and b) if an item has anything under that key you know it is a custom item
plucky cliff
Ye but for each piece should i use different key or same key ?
eternal night
Well in the case of a key like customItemIdentifier
you'd reuse the key
and change the value
you need to know the key to lookup the value in the end
so a unique key for each item doesn't make much sense
plucky cliff
but same key with different value make sense, right ?

well sorting can be done like this where map is your hashmap
List<Map.Entry<UUID, Integer>> list = new LinkedList<>(map.entrySet());
list.sort(Map.Entry.comparingByValue());

for (Map.Entry<UUID, Integer> entry : list) {
