Do I have to import the API or something?

[worldly ingot]

No, you're just making a web request

[woeful moon]

Ok, sounds good

[quaint mantle]

I start the server, when I join it will time me out then say ./start.sh does not exist, stopping the server!

[novel lodge]

How can I wait without halting the entire server?

[quaint mantle]

I don't have an sh file do i create one and put this in it?

[mortal hare]

just create it

[quaint mantle]

okay

[woeful moon]

Question, does this apply to plugin creation?
https://www.youtube.com/watch?v=YYP_dNSYOG4

[mortal hare]

if you're on windows create .bat file

yes it does

its in java

[woeful moon]

Ok :D

[mortal hare]

you just need to make it work via bukkit plugin API

handle the plugin itself

[quaint mantle]

I created the file and pasted the stuff in it now do i run the server by opening the new .bat file or the old one @mortal hare

[mortal hare]

have you changed those?

[quaint mantle]

ye

[mortal hare]

if you're on linux terminal:
chmod +x [filename].sh
./[filename].sh
if you're on windows:
just double click it, or from cmd.exe inside directory - [filename].bat

Is there a simple database/method to store Usernames and their points?

[mortal hare]

have you created .sh file on windows

or .bat file one?

[quaint mantle]

.bat

exactly

[mortal hare]

are you running on some kind of ARM based windows pc ?

is it like surface shit

[quaint mantle]

nope

[mortal hare]

maybe its windows defender

[quaint mantle]

ill disable it and let you know

[mortal hare]

can you do a screenshot?

[quaint mantle]

can't upload images here

[mortal hare]

on the edited file

[quaint mantle]

okay

[mortal hare]

login to your spigotmc account

and verify the discord account

and you'll be able to do that here

I am trying to cancel the mushroom block state update but for some reason it still changes

[mortal hare]

have you tried debugging it if it does happen for mushrooms on that event?

[quaint mantle]

it is fired yes

[main dew]

How the best metod to set all chunk to max bright? (max light and max skylight)

[mortal hare]

not sure mate, i've rarely used that event

[quaint mantle]

Thank you it works now it was windows defender, ill see if I can join or it's still giving me the same error

Now it's giving me this infinite error and won't let me join, timed out @mortal hare

[quaint mantle]

anyone that can help me out here?

it's really weird, the event cancel should work by itself

[mortal hare]

some kind of powerranks plugin cause errors

what java version have you got on your computer

some software just vomits errors when it seems older or newer java version

[quaint mantle]

openjdk version "1.8.0_282"

[mortal hare]

minecraft version?

[quaint mantle]

1.16.5

[mortal hare]

try installing java 11

its now industry standard

java 8 is deprecated

[quaint mantle]

this error wasn't happening but as soon as i installed essentials everything is ruined

[quaint mantle]

aight

[mortal hare]

why wouldnt you restore the blockstate whenever someone breaks or places mushroom blocks

[quaint mantle]

?

custom blocks

[mortal hare]

yes

but you can listen to onBlockBreak or onBlockPlace events and check if block is mushroom type

if its is restore the blockstate

??

[quaint mantle]

still it changes the blocks around it

because that is how the mushroom block works

[mortal hare]

what's stopping you to check 3x3 block area around the broken block

[quaint mantle]

that is why I need to listen to the BlockPhysicsEvent

then it will change the ones around the ones that are placed and again and again

[mortal hare]

you only need to change 6 block's blockstates

since it only changes the blocks around the broken or placed block

if that's not an option for you and spigot doesn't work

try to listen to the packet which changes the block type

and create your own custom bukkit event

or handle it from there synchronised to the main server thread (BukkitRunnables)

[main dew]

What the best metod to set all chunk to max bright? (max light and max skylight)

[mortal hare]

Never done it so i don't know if spigot api supplies light api

but you can do it manually via NMS i think

[quaint mantle]

this will change the block states of the changed blocks around it

[opal sluice]

Hey, can someone help me to find out how could I change the crafting slots of the player inventory ?

[mortal hare]

check if it is the mushroom block

then change the block state

[opal sluice]

Cause it seems that it is a sort of view and can't get the actual slot

[quaint mantle]

if its for example a 100x100 and you place one in the center

you will have to change for each one of those blocks the block state because when you update one it will update the others again and again

[mortal hare]

idk what you're talking but it only changes the blockstates around the broken block

unless this is different in older versions of minecraft

if it would work like that, i would be lagging p2w creative server straight away

heck no need for creative servers, you can do it in survival with silk touch enchantment and a big ass area

[cinder thistle]

p2w? creative?

[mortal hare]

there are some

ngl

[quaint mantle]

if you change the state of a block

the others around it will change

[cinder thistle]

you can "win" on a creative server??

ig competitions

[mortal hare]

well maybe mushroom blocks don't fire that event, but block around it like for example do

i dunno

[quaint mantle]

im running one a 64 bit operating system, I downloaded the 64 bit java sdk 11 but it doesn't open

it confirms that it will change stuff on this pc, I click yes and it won't open

even in task manager there is nothing

[cinder thistle]

try restarting your pc?

never heard that one before

[quaint mantle]

alright

[mortal hare]

i've never heard about this too

are you sure you haven't downloaded some kind of trojan virus?

[cinder thistle]

bruh

[mortal hare]

i use amazon coretto

[cinder thistle]

why does everybody assume that when something doesn't work it's immediately a virus

why not just use adoptopenjdk smh

[mortal hare]

because first signs of RAT or trojan is to hide itself

because the download speeds of adoptjdk were slow

when i downloaded it

[cinder thistle]

bruh

download from a mirror

[left swift]

How can i make nametag prefix? I tried with scoreboard teams, but when i make prefix type "&cPREFIX " so the player's name is still white

[mortal hare]

it was like 3kbps

for 100-200 mb package

[cinder thistle]

y'all aren't that patient?

I had to put up with that for years

[novel lodge]

How could I make something run every few seconds?

[mortal hare]

use ChatColor enums

[cinder thistle]

BukkitRunnable

[left swift]

yeah i make it witch chatColor, but the result is the same

[tribal holly]

is there any way to set only 1 heart of absorption ? (the potion effect is minimum 4 hearts) ?

[mortal hare]

https://tenor.com/view/spongebob-nickelodeon-shrug-spongebob-squarepants-nothing-gif-16934569

[quiet ice]

well, damage the player

[mortal hare]

use scaledhealth method

[tribal holly]

he will take knockback

[mortal hare]

or send the packet

[quiet ice]

good point

[tribal holly]

never heard about it

[mortal hare]

#player.setHealthScale​(double scale)

[tribal holly]

hoooo

[mortal hare]

this will scale your health bar

[tribal holly]

well okay but i wanna have the visual effect of the absorption

[mortal hare]

more hearts or less hearts

[cinder thistle]

that's half a heart btw

4 = 2 hearts

2 = 1 heart

[tribal holly]

yeah sorry wrong word

[mortal hare]

i don't know much of the potion api of bukkit, but you could also send packet which sets the health of player, but its synced with the server so if you set it to 0 hearts, the player dies

[tribal holly]

but the setHeal method change permanant heart not absorption heart

[mortal hare]

in ealier days of minecraft you could've glitched the minecraft client in to removing the health bar

miss that glitch so much

i think you couldn't set it normal hearts to the absorption ones if you're talking about it

you can set it to wither ones or hardcore ones tho

if you're talking one absportion heart above the normal hearts then yes you can

but im not sure if spigot api allows it

or you need to handle it yourself

im not an expert in spigot api

[tribal holly]

with packet ?

[mortal hare]

yes but im not sure, there could be a better way to do that

[tribal holly]

hmmm

[mortal hare]

and im pretty sure there is

[quaint mantle]

nope

I have my antivirus run 24/7

[mortal hare]

found it

[tribal holly]

well

[quaint mantle]

and btw, restarting doesn't fix it

[tribal holly]

what an ass hole i am

[mortal hare]

#DamageableEntity.setAbsorptionAmount(double amount)

[vague mason]

What Absorption means?

[mortal hare]

that yellow hearts

above the normal ones

[vague mason]

Thanks

[mortal hare]

its a potion effect

[tribal holly]

thanks for help this is what i need

[mortal hare]

np

[quaint mantle]

yo I fixed it

one of powerranks's ymls was corrupted

thanks dovidas for the help : )

[novel lodge]

How can I send an actionbar to somebody

[mortal hare]

np

[mortal hare]

Packets or Spigot API

[lost matrix]

player.spigot().sendMessage(ChatMessageType.ACTION_BAR, someComponent);

[mortal hare]

oh

how strange it looks

but at the same time correct

Message can be sent via action bar, title, subtitle, chat

[lost matrix]

So for example

    Player player = ...;
    BaseComponent[] components = new ComponentBuilder().append("Some text").create();
    player.spigot().sendMessage(ChatMessageType.ACTION_BAR, components);

[mortal hare]

so its better to group them i guess

[novel lodge]

Ty

[mortal hare]

Whoever thought of that component api integration, hands down

But enum name shouldn't be ChatMessageType

Chat is the type of message

in this case

name makes no sense

but i guess this was left out because of bungeecord component api

before it was integrated with other types of messages

[rugged topaz]

    public String getTexture(final UUID u) {
        URL urlUUID = null;

        try {
            urlUUID = new URL("https://sessionserver.mojang.com/session/minecraft/profile/" + u + "?unsigned=false");
        } catch (MalformedURLException ignored) {
        }

        try {
            InputStreamReader reader = new InputStreamReader(urlUUID.openStream());
            JsonObject json = new JsonParser().parse(reader).getAsJsonObject().get("properties").getAsJsonArray().get(0).getAsJsonObject();
            return json.get("value").getAsString();
        } catch (IOException e) {
            return null;
        }
    }

need a method that doesn't kill tps 😬

[earnest junco]

It should be ^^ it's all the same packet
https://wiki.vg/Protocol#Chat_Message_.28clientbound.29

[earnest junco]

It "kills TPS" because you make a web request synchronously. Put it inside a CompletableFuture that you run async and you're fine.

[quaint mantle]

Hi, I have this code:

List<ItemStack> drops = event.getDrops();
        
String items = drops.stream()
           .map(it -> String.format("%d %s",it.getAmount(),it.getType()))
           .collect(Collectors.joining(", "));
``` that prints me this: `1 IRON_SHOVEL`

And I want to print me this: `:iron_shovel: x1`

How can I do that?

[rugged topaz]

and to use the return of a completablefuture?

[eternal night]

just change your format and lowercase the get type ?

[rugged topaz]

such as passing the result string type as the texture of an item

i'm not sure how to incorporate .thenAccept in there

[earnest junco]

CompletableFuture.supplyAsync(() -> {
    // ... web request
    return "texture";
}).thenAccept(result -> {
    player.sendMessage(result);
});

Be careful though, you're not on the main thread in #thenAccept, so you might need to call some API through BukkitScheduler#runTask.

[eternal night]

what prevents you from doing something like this ```java
String items = input.stream()
.map(item -> String.format(":%s: x%d", item.getType().toString().toLowerCase(), item.getAmount()))
.collect(Collectors.joining(", "));

[gritty mist]

can i turn a string into an integer

?

[rugged topaz]

    gui.setItem(13, getTexture(visiting.getUniqueId()).thenAccept(texture -> {
        createSkull(texture, 1, "&avisit", "&7Player: " + inst.getRankedName(visiting));
    }));

    public CompletableFuture<String> getTexture(final UUID u) {
        CompletableFuture<String> result = new CompletableFuture<>();
        try {
            InputStreamReader reader = new InputStreamReader(new URL("https://sessionserver.mojang.com/session/minecraft/profile/" + u + "?unsigned=false").openStream());
            JsonObject json = new JsonParser().parse(reader).getAsJsonObject().get("properties").getAsJsonArray().get(0).getAsJsonObject();
            result.complete(json.get("value").getAsString());
        } catch (IOException e) {
            result.completeExceptionally(e);
        }
        return result;
    }

look right?

cause apparently i'm doing something wrong with the first line (:

[eternal night]

but your getTexture method is still on the main thread

why use a completable future then

[rugged topaz]

i'll async

mb

needa fix this error tho

[eternal night]

Well gui is an Inventory I am guessing ?

[rugged topaz]

yes

[eternal night]

it expects an ItemStack not a CompletableFuture<ItemStack>

so you will have to either CompletableFuture#join

which holds the thread you call this on until the future resolves

[rugged topaz]

sounds like we're not doing that

[eternal night]

Yeah xD

tho joining would kinda defeat the purpose

because then you could just run all of this on the same thread anyway

so I guess you would more do a

getTexture(...).thenApply(texture -> createSkull(...)).thenAccept(skullStack -> gui.setItem(13, skullStack))

[winged mica]

try calling that with somehting like this

[earnest junco]

why two then accepts? one is enough lol

[winged mica]

this.runTaskTimer(getTexture, 0, 20L);

it lauches a new thread

[eternal night]

idk the entire point of reactive programming is splitting these up no ?

[winged mica]

and doesn't block the main one

[eternal night]

but yeah you could just do a single thenAccept

¯_(ツ)_/¯

[novel lodge]

Is there a way I could stop a projectile from damaging a specific plaer

[mortal hare]

paperspigot

onProjectileCollide event on paper

[opal sluice]

Hi, is there an event triggered by the usage of the crafting recipe ?

[gritty mist]

        if(!(sender instanceof Player)){
            return false;
        }
        Player player = (Player) sender;
        if(args.length == 1){
            try{
                String argsValue = args[0];
                float FlySpeed = Float.parseFloat(argsValue);
                player.setFlySpeed(FlySpeed);
            }catch (Exception e){
                player.sendMessage(ChatColor.RED + "Please use a float value !");
            }
        }

        return true;
    }```
this is supposed to change the flyspeed to the input value but somehow it throws an error each time

[mortal hare]

Don't catch exception in abstract Exception form

[gritty mist]

event entitydamagebyentity e.setCancelled(true);

[mortal hare]

it can lead to bad both in bad code reading quality and some problems, like when threads fails

etc

[gritty mist]

ok is there a way i can verify if the input value is a float ?

[mortal hare]

you're already doing it .

try using #String.trim()

wait

nvm

yes

[prime nimbus]

public class main extends JavaPlugin {
    private World world;

    @Override
    public void onEnable() {
        World delete = Bukkit.getWorld("world_the_end");
        File deleteFolder = delete.getWorldFolder();
        World unload = Bukkit.getWorld("world_the_end");
        unloadWorld(unload);
        deleteWorld(deleteFolder);

    }

    @Override
    public void onDisable() {

    }

    public void unloadWorld(World world) {
        this.world = Bukkit.getWorld("");
        if(!world.equals(null)) {
            Bukkit.getServer().unloadWorld(world, true);
        }
    }

    public boolean deleteWorld(File path) {
        if(path.exists()) {
            File files[] = path.listFiles();
            for(int i=0; i<files.length; i++) {
                if(files[i].isDirectory()) {
                    deleteWorld(files[i]);
                } else {
                    files[i].delete();
                }
            }
        }
        return(path.delete());
    }
}

it deletes the end every time the server starts up, but it dosent create it again so i tried setting the plugin to run before the world was loaded but since the location of the world is received only after the world it loaded, it dosnet work, so it there any way to hardcode the location of then end dimension or recreate the world after it has been deleted

[mortal hare]

try using #String.trim()

for an argument

and see if it works

wdym by location of world

folder path location? @prime nimbus

[prime nimbus]

yes

[gritty mist]

            try{
                String argsValue = args[0].trim();
                float FlySpeed = Float.parseFloat(argsValue);
                player.setFlySpeed(FlySpeed);
            }catch (Exception e){
                player.sendMessage(ChatColor.RED + "Please use a float value !");
            }
        }```
like that ?

[mortal hare]

yes

[mortal hare]

well you can use plugin's data folder path location and traverse it back two folders to get root location of your minecraft server folder

[prime nimbus]

im not sure on how to do that

[gritty mist]

it stills throws an error

[prime nimbus]

sorry im pretty new to java

[mortal hare]

File endFolderLoc = new File(#Plugin.getDataFolder().getParentFile().getParentFile(), "world_the_end")

[wet breach]

if you are that new that you don't know basic Java API stuff, then you probably should be learning more about said API that is part of the language you want to learn.

[mortal hare]

what input do you input it?

[prime nimbus]

oh okay, ill try it

[gritty mist]

/speed 10.0

[mortal hare]

try adding f to the back

[torn oyster]

why is this happening (bungeecord)

this is a tabexecutor thingy

but when i try typing "un"

[mortal hare]

or try using Float.valueOf() instead

[torn oyster]

it doesnt recommend unsponsored

[mortal hare]

@gritty mist

[gritty mist]

still doesnt work

[mortal hare]

have you tried switching clients?

[torn oyster]

wdym

[mortal hare]

or maybe you send the tab completion every letter?

[torn oyster]

how do i do that

i have this in my command class

    @Override
    public Iterable<String> onTabComplete(CommandSender commandSender, String[] args) {
        List<String> names = new ArrayList<>();

        for (String s : BanManager.getBanManager().config.getKeys()) {
            String name = BanManager.getBanManager().config.getString(s + ".name");
            names.add(name);
        }
        return names;
    }```

[mortal hare]

ik why

i think

[torn oyster]

this is my first time using tabexecutor/tabcomplete

[mortal hare]

Try saving the names in lowercase

[torn oyster]

so idk how to use it

[mortal hare]

i think its casesensitive

[torn oyster]

nope

i tried that

i typed "Un"

instead

but it still doesnt work

[mortal hare]

that's strange

i've never had these kind of issues before

[gritty mist]

it doesnt work with the valueof to

unless I wrote it wrong

float FlySpeed = Float.valueOf(Float.parseFloat(argsValue));

[mortal hare]

you wrote it wrong

float flySpeed = Float.valueOf(argsValue);

[gritty mist]

lets try it

[mortal hare]

you don't need trim() in this case

[gritty mist]

ok

oh yeah it works im as fast as Flash McQueen

[mortal hare]

https://tenor.com/view/kachow-cars-lightning-mc-queen-pixar-disney-gif-5931942

ParseFloat is raw type of valueOf(), it has more strict rules

that's why probs it didn't worked

[gritty mist]

so if i want to slow down a bit can I write ?
float flySpeed = Float.valueOf(argsValue)/10;

[mortal hare]

yes

since returned number from static method is float

[gritty mist]

bcz 10 is real fast

ok perfect

[torn oyster]

why is this happening (bungeecord)
https://cdn.discordapp.com/attachments/741875863271899136/834170095743926362/unknown.png

this is a tabexecutor thingy

it doesn't suggest "Unsponsored"

        List<String> names = new ArrayList<>();

        for (String s : BanManager.getBanManager().config.getKeys()) {
            String name = BanManager.getBanManager().config.getString(s + ".name");
            names.add(name);
        }
        return names;
    }```

[mortal hare]

Have you tried add random tab completion to it?

maybe bungeecord lacks this feature

and you would need to implement it yourself

with contains

idk

[waxen plinth]

Cause you're not filtering out suggestions that don't match the partial string

That's also a pretty slow way of doing it - if you have a lot of bans, that will definitely cause lag on tab complete

What you want to do is keep a cached set/list of bans somewhere

And then when they're tab completed, you filter out ones that do not start with the partial string in the last argument passed

[torn oyster]

if (name.startsWith(args[0])) {
names.add(name);
}

would that work

[waxen plinth]

No

It would error if they haven't entered any args yet

[mortal hare]

wat. Bukkit Configuration API is Cached. There's MemorySection class dedicated for this

[lost matrix]

FileConfiguration is just a glorified HashMap that was loaded from a file

[mortal hare]

Its a wrapper of SnakeYaml

still

the configuration is cached

there's no need to create new references to it

[waxen plinth]

Yeah he is literally fetching potentially hundreds/thousands of values from a hash map every time someone types a character

That's a bad idea

[mortal hare]

why? map's contains() method time complexity is O(1)

how is that different from hashset

which uses hashmap internally

[waxen plinth]

Because if you cache them in a set the elements are just in there and you can iterate them

Instead of fetching them all from a hash map

Like, yes, hash maps are efficient

But hashing is still an operation that takes much more time than native array access

Iterating a hash set is only marginally slower than iterating an array

[mortal hare]

well for putting this into list or primitive array your statement correct, but putting it in set is as not efficient as the hashmap

[waxen plinth]

More than just the runtime complexity of an algorithm matters

???

In a set it's already in there

What he's doing is literally going through and fetching each value from a hashmap, essentially

[lost matrix]

Depends on the element count. Array iteration is several times faster that Set iteration. Dont underestimate that.

[waxen plinth]

Calling get on a hashmap to generate each element

That is significantly slower than just using an already-generated hashset

[lost matrix]

That for sure

[waxen plinth]

This is true but you do need fast remove from the cache

And an array/list can't provide that

This guy is getting a set of keys, presumably UUID keys, iterating it, and then for each key, fetching a value from a hashmap

[mortal hare]

so you're saying that everytime hashmap get an instruction to check if it contains the object it calculates all the hashcodes of the objects

that sound inefficient

[waxen plinth]

???

No what the fuck

He is getting the set of UUIDs as keys

(Strings, mind you)

Then generating a list of the banned players by iterating that list and getting each player's name from a hashmap

To generate a hash of each string it needs to iterate all the characters

[opal sluice]

Is there a way to cancel the autocraft of the crafting recipe book ?

[waxen plinth]

UUIDs are like 48 characters in length, right?

[mortal hare]

no im talking about hashset vs hashmap performance on contains()

[waxen plinth]

Bro

Oh my god

That's not what we're talking about

HashSet is backed by a HashMap

[lost matrix]

They are literally the same data structure. HashSet is just a HashMap without values

[waxen plinth]

That's not what I'm talking about

What I'm talking about is that his way of doing it requires hashing potentially hundreds to thousands of elements every time someone types a character

[mortal hare]

that's what i was talking about but i got confused because he started talking about runtime complexity

[waxen plinth]

Which is going to create a hell of a lot more issues than just iterating a cached HashSet of those same values already fetched

I'm not talking about the runtime complexity

They have the same runtime complexity but his way is still a lot slower because the O(1) operations are much more expensive

Just because it doesn't take more time with more elements doesn't mean it can't still be slow

[mortal hare]

i got it, i just got confused by your explanation, no worries

[lost matrix]

One could use a tree approach to calculate all the possible inputs beforehand 😄

[waxen plinth]

This is true

A prefix tree would be a very elegant solution

[lost matrix]

So
u
un
und
unde
...
all point to
undermined and undetermined

With depth first traversing and early escaping this would be quite efficient. O(log n)

[waxen plinth]

Yeah you could just get the node for the current partial string

And then iterate the subtree to get the completions

You could technically have an O(1) solution but it would be pretty memory intensive

Storing a list of possible completions at each node

[lost matrix]

Yeah XD

[waxen plinth]

O(log n) is perfectly acceptable here

Hm..

It's O(n) for the base case

When they haven't typed any characters yet

Then again it's O(n) no matter what you do

Because it has to serialize and send the completions

[mortal hare]

well i have command node system which acts like it, by iterating the nodes

eh its not the best one

but fits well for me

brigadier is still better

[tough zephyr]

Is it possible to transition the worldborder by position rather then size? Like on warzone how the border moves

[quaint mantle]

Call of Duty in Minecraft!

[tough zephyr]

Pretty much the goal, yes

[quaint mantle]

Hunger Games Battle Royale

shit

is it survival or hunger games

[tough zephyr]

Hungergames sort of

Setting the center wont transition though. Damn shame

Only the size allows for a transition

[quaint mantle]

why not use a task

[tough zephyr]

Not SMOOTH enough

[quaint mantle]

too damn picky

[tough zephyr]

https://gyazo.com/f28d5660931834636cd4b03600ccd98e

The transition effect looks really nice

[lost matrix]

If you move the border with a task then it should be quite smooth

[safe granite]

Hello,

[quaint mantle]

Hello,

[safe granite]

im currently making a plugin to change skin texture of a player

[tough zephyr]

@lost matrix Are you MOVING the border's center?

I mean like MIGRATE the border to another center

Not the size

[lost matrix]

You need to remove the "textures" property then add your own again. Dont forget that it needs a signature.

[lost matrix]

Yes im moving the center of the border

[tough zephyr]

Very cool, I'll give it a go

[safe granite]

@lost matrix yes that im doing

and its works well

but idk what the best way to reload skin view for other player

simply hide and show ?

and for a self view

[quaint mantle]

teleport to other world and come back if you want it to be simple

[lost matrix]

You need to. There is no other way.
But i would simply use
player.spigot().respawn();

[safe granite]

that i was doing but i didnt know if it was a good way

respawning looks a better way

[lost matrix]

I dont think there is a better way.

1. Change the GameProfile using nms or reflections
2. Respawn the player using spigot API

[safe granite]

is nms better than reflections

or just different way

im doing it with nms right now

[lost matrix]

nms makes your plugin only viable for one exact version.
Using reflections might make it compatible with multiple ones.
You can also use a multi module setup to write the same code for each version and implement an interface that is used in your plugin.

But reflections are risky and will be slower if you dont cache them

[safe granite]

okok ty for your explanation

I will look more details on the internet

ive tried with player.spigot().respawn();

but it looks to doing nothing

[sullen marlin]

that method respawns a dead player

not whatever youre doing

[safe granite]

so how cand i o pls ?

its works pretty well when im teleporting a player to another dimension then tp him back to his original position

but it dont looks like clean to do it like that

[quaint mantle]

What’s the difference between a hash set and arraylist? In terms of the data it stores?

[tough zephyr]

@quaint mantle HashSet = wrapper for HashMap. So O(1) gets/puts/removes

Arraylist is a wrapper for an array. So just a generic list

[quaint mantle]

Alright cheers

[tough zephyr]

If you're just iterating the data, use an arraylist. Otherwise, a hashset

[quaint mantle]

Cheers

[ashen flicker]

Is there a way to have a chat click that runs code rather than just a command?

[dusty herald]

🤷 why not have a command that runs code

[ashen flicker]

I'd just prefer not to register a command if I can avoid it

[lost matrix]

Only with some trickery. So you would still need a command but with a dynamically generated secret that is mapped to a delegated function

[ashen flicker]

So like, I could make an api for it that does it or something maybe? I'd need an interface I think

[lost matrix]

Using one of the functional interfaces should suffice

[ashen flicker]

Like?

Are you saying making my own interface for it would be pointless

[lost matrix]

Map<String, Consumer<Player>>

[ashen flicker]

Ah okay, I've not actually used Consumer before but let me look at it, probably is what I need

[stone sinew]

You can check PlayerPreProcessCommandEvent Or check for the click in chat.

[ashen flicker]

Well I'm gonna probably do that anyways, but I need to register the command. Which is fine. Why would I need to use Consumer actually @lost matrix? I just need to run code, couldn't I use like Runnable or something?

[drowsy helm]

consumables run code

Consumeable<int> myConsumable = i -> { //do stuff};

[stone sinew]

Don't have to register the command if you check the pre event

[lost matrix]

Ill write you and example of the thing i just thought of.

[ashen flicker]

Okay awesome thx

[dusty herald]

I haven't put must testing into PlayerPreProcessCommandEvent but is it possible to have tab completions?

[tawdry rampart]

Hey, how would I access for example the playerList string from the Bungee plugin message in other places around my plugin?
I have the actual thing done that gets the player list and then the subchannel listener, but just unsure on how to get that string..

[lost matrix]

Either pass it down to your other instances in a reactive way or cache it using a Map<>
Normally you would use a system, where one instance requests the name and sends a Callback
or Consumer<String> with the request which later consumes the received name.

[lost matrix]

Ok so it works and the user can only click the message once. After that clicking is useless.

[dusty herald]

what is your username

that's an amazing username lmao

[ashen flicker]

Yea I mean as long as that's per user and not just 1 click over all that's probably fine

[eternal night]

iconic username

[lost matrix]

https://gist.github.com/Flo0/e3730a8f8ba0dd58aa91b0d528777966

This is how ive done it. Quite compact actually

[stone sinew]

Klick???

[woeful moon]

Hello. Doing webhook programming right now. Everything works well, one question though: For setting the image/thumbnail, you need a String (a url to the image). Which image hosting website do you guys suggest?

[lost matrix]

In the onJoin method you can see how to assemble such a command

[tawdry rampart]

If I were to put it all into the actual subchannel listener, would I just be able to output playerList from there or would that not work at all?

[lost matrix]

Dont do that. Separation of concerns. A listener should only listen and then pass its results to other classes.

[ashen flicker]

Ah I see how it works

[tawdry rampart]

Alright, sorry still am a bit confused on all of the other stuff you said though

[lost matrix]

Ill write you and example

[tawdry rampart]

Alright

[unreal finch]

Would anyone know why setSitting() wouldnt be working for me? I’ve confirmed that the code works entirely and there are no errors whatsoever. The wolf in question just wont stand up

[lost matrix]

This one would be used for executing something with the players IP for example:
https://gist.github.com/Flo0/9c0bbf1c4f175ec924353c079169aad1

You could also design this to use a CompletableFuture.

[tawdry rampart]

Alright thank makes more sense, thanks. Also, would I have to just make a new class for each one if I use multiple things or could I put it all in one somehow?

[lost matrix]

But at second glance this looks quite complicated... Non linear programs can get confusing quite fast.

[lost matrix]

You could probably throw them all in one class. But separation is way cleaner.

[tawdry rampart]

Yeah that's understandable, thanks

https://paste.gg/p/anonymous/f1d79b7cfad74bd1a93c0afeb7f1870e

im using gradle

[lost matrix]

First of all the scope should be compileOnly instead of implementation

[lost matrix]

What spigot version?

And why the heck do you need an inner class for this?

[hushed crescent]

.

Maybe I am overly object oriented

😆

[hushed crescent]

Latest

[glossy dirge]

how you use latest spigot api ?

[hushed crescent]

I created a spigot project with a plugin in intellij

"Minecraft Integration"

[lost matrix]

This has nothing to do with object orientation. Pls show how you register the event. And pls unpack this inner class.

[hushed crescent]

Yeah I removed the inner class.

[lost matrix]

Pls show how you register the event

[quaint mantle]

@lost matrix are you in germany

[hushed crescent]

public final class TNS extends JavaPlugin {

    @Override
    public void onEnable() {
        System.out.println("Wassup");
        getServer().getPluginManager().registerEvents(new PlantSapling);
    }

    @Override
    public void onDisable() {
        // Plugin shutdown logic
    }
}```

[quaint mantle]

well thats not java

well thats not spigot

[hushed crescent]

...

[lost matrix]

This wont compile. new <ClassName>(ConstructorParams)

so new PlantSapling() in your case

[hushed crescent]

Yeah, I fixed it.

Still getting the same error though.

[eternal night]

Also you'll need to provide the plugin instance

[hushed crescent]

.

[hushed crescent]

Pardon?

[eternal night]

So new PlantSaplling(), this

[hushed crescent]

Oh

[eternal night]

This being the reference to the current instance of your TNS class

[hushed crescent]

That fixed everything

Well, thank you haha

[eternal night]

Hope you understood why that fixed it 😅

[hushed crescent]

Why did I need to reference my TNS Class?

May I ask what those do?

[eternal night]

Spigot basically wants to know what plugin is registering the listener here. So besides providing your listener instance (new PlantSappling()) you also need to provide your instance of the Plugin interface which is, when executing from onEnable just this

[lost matrix]

Just tested a clean gradle project. Works fine.
Make sure to add at least those repos:

repositories {
    mavenCentral()
    maven { url 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/' }
    maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
    maven { url 'https://hub.spigotmc.org/nexus/content/repositories/snapshots/' }
}

And this dependency

dependencies {
    ...
    compileOnly 'org.spigotmc:spigot-api:1.16.5-R0.1-SNAPSHOT'
}

[hushed crescent]

They are already added btw

inside a pom.xml

Not sure what that is

Is that like a package.json but for java?

[eternal night]

I think this is for someone else

XD

[hushed crescent]

Oh

[quaint mantle]

hello how would i add the string? getConfig().addDefault("message"); I have to do something... i just am not sure what

[lost matrix]

Describe what you are trying to do

[quaint mantle]

im trying to have a onjoin message taht u can change

and i tried manually making the config with creating a file but it didn't work

[lost matrix]

Ok so there are two approaches for default configurations.

1. You just write and put a config.yml in your plugin and then save it when the server starts
2. You generate a config.yml from code when the server starts

Which one do you prefer?

[glossy dirge]

its still not working for me

[quaint mantle]

I tried the first one but that doesn't work for me and now im trying to do the second one

[glossy dirge]

but when i created a clean project its working

[lost matrix]

Then your old project is somehow malformed

[lost matrix]

I would go for a file that you deliver with the plugin for now. I think thats simpler.

[quaint mantle]

I have tried that but it doesn't work

[lost matrix]

Lets make it work then.

[quaint mantle]

I'll again thought thanks!

tysm :)

[lost matrix]

Do you use maven or do you add spigot to your project manually (as library)

[quaint mantle]

spigot api

[lost matrix]

Ok so you manually add the spigot api i suppose.
Then go to your src folder and create a new file.
Name it however you want. So messages.yml should suffice.

Content should look similar to this:

messages:
  on-join-message: "This is a default message."

[quaint mantle]

ok

[glossy dirge]

malformed ?

[quaint mantle]

player.sendMessage(getConfig().getString("on-join-message"));would it be that?

[lost matrix]

Then (just to be sure) compile your plugin and open the jar with a compession program like 7zip or winrar to see if the yml is actually in your final jar file.

[quaint mantle]

ok

[quaint mantle]

yup

it shows up

[lost matrix]

Next you should export the file when your plugin starts.

  @Override
  public void onEnable() {
    setupFiles();
  }

  private void setupFiles() {
    this.getDataFolder().mkdirs(); // Creates plugin folder
    this.saveResource("messages.yml", false); // Saves the messages.yml if it doesnt exist
  }

create a method named setupFiles() where you handle all your io setup stuff.
Normally you would create a FileManager class that handles all that so your JavaPlugin class doesnt get messy

[quaint mantle]

ok

[lost matrix]

If this is done. Compile your plugin and run it once with your server. You should then see a messages.yml file in your plugin folder

[quaint mantle]

ok thx

[lost matrix]

  private void setupFiles() {
    this.getDataFolder().mkdirs();
    this.saveResource("messages.yml", false);

    // Create a file variable. This is not the actual file on your hard drive but only a representation for Java to work with
    File messagesFile = new File(this.getDataFolder(), "messages.yml");

    // Load the content from that file into a FileConfiguration. This reads the whole file at once.
    FileConfiguration messagesConfig = YamlConfiguration.loadConfiguration(messagesFile);

    // Now you can access all the content using the methods from FileConfiguration
    String message = messagesConfig.getString("messages.on-join-message");
    
    // Print out the message we just got from our FileConfiguration
    this.getLogger().info(message);
  }

[hushed crescent]

Thank you @eternal night and @lost matrix! My first ever plugin works

I am so happy

Now I just need to find a way to parse the stuff onto a scoreboard

[tawdry rampart]

Alright, so I have the player list fetcher working (I think) now it's a matter of trying to figure out how to access it from another class. The actual event is called in onEnable(), but this is just losing me

[lost matrix]

Yeah thats just ugly. Mind sharing your list fetcher as well as the method where you want to use it?

[tawdry rampart]

Yeah sure let me upload it to github or smtn

[quaint mantle]

so what would I put in the onjoin event?

[tawdry rampart]

Mind the messy shit:
https://gist.github.com/PrinceBunBun981/dc56752542b62efcd4f389b231d99b49

[quaint mantle]

whatt

I see that it would print out the message but would I just put that in the event method?

[lost matrix]

You first need to somehow gain access to the FileConfiguration you just created. For this you could create a field in your JavaPlugin class.
Then you need to pass the FileConfiguration in the construcor of your listener class like this:

public class SpigotCore extends JavaPlugin {

  private FileConfiguration messagesConfiguration;

  @Override
  public void onEnable() {
    this.setupFiles();
    
    JoinListener listener = new JoinListener(messagesConfiguration);
    Bukkit.getPluginManager().registerEvents(listener, this);
  }

  private void setupFiles() {
    this.getDataFolder().mkdirs();
    this.saveResource("messages.yml", false);
    File messagesFile = new File(this.getDataFolder(), "messages.yml");
    this.messagesConfiguration = YamlConfiguration.loadConfiguration(messagesFile);
  }

}

Or you create a getter method in your JavaPlugin class so you can get the FileConfiguration from other classes like this:

public class SpigotCore extends JavaPlugin implements Listener {

  private FileConfiguration messagesConfiguration;

  @Override
  public void onEnable() {
    this.setupFiles();

    JoinListener listener = new JoinListener(this);
    Bukkit.getPluginManager().registerEvents(listener, this);
  }

  private void setupFiles() {
    this.getDataFolder().mkdirs();
    this.saveResource("messages.yml", false);
    File messagesFile = new File(this.getDataFolder(), "messages.yml");
    this.messagesConfiguration = YamlConfiguration.loadConfiguration(messagesFile);
  }

  public FileConfiguration getMessages() {
    return this.messagesConfiguration;
  }

}

[quaint mantle]

ok thanks

[lost matrix]

Ok so first of all playerList.toString() This will just print out the memory location of that array.
You are converting a String to a String[] and then back to a String. Just let the playerList variable be a String.

[tawdry rampart]

Only thing is the actual output is String[] playerList = in.readUTF().split(", "); (according to the messaging docs at least)

[lost matrix]

Then the correct usage of your current setup would be

    final Player player = (Player) sender;
    this.playerListFetcher.fetchPlayerListAndExecute(player, (server, playerList) -> this.sendList(player, server, playerList));

It should work but its quite hard to understand.

[lost matrix]

in.readUTF() returns a String
in.readUTF().split(", "); splits this String at each comma and makes an array out of it

[tawdry rampart]

Alright, so thankfully when removing .toString() the errors went away, but lemme test it

[tawdry rampart]

Okay, so I got ALL: [Ljava.lang.String;@46088d50 in game as the message and a null pointer exception in the console. (https://paste.helpch.at/tejedufeqe.bash)

Oh I'm a dumbass

Still had .toString() in the consumer thing, now that I've changed String[] to just String

[lost matrix]

Thats the memory location of your array (as i told you)
And you should only have one exact instance of PlayerListFetcher because currently each time you execute the command you register
a new channel and a new listener. Which is a straight memory leak. So create one instance of PlayerListFetcher in your onEnable
and pass it to other instances where this instance is needed.

[lost matrix]

Yes.
Replace final String[] playerList = in.readUTF().split(", "); with final String playerList = in.readUTF();

[tawdry rampart]

Yeah, just re-read one of your previous messages (once again dumbass me)

[lost matrix]

All good

[tawdry rampart]

Alright! Sends the message with all players, also removed it making a new one, thanks for putting up with me lmao

i will explain everything

do u see the string builder?

[drowsy helm]

Bukkit.getOnlinePlayers().toString().contains(args[i])

yes

[south onyx]

no wait

this part

if (invalidPlayers.toString() != null && alreadyStalker != null) {
                            player.sendMessage(ChatColor.GREEN + "Removed players that were listed, except " + alreadyStalker.toString() + ",because these players are already not stalkers, and also except " + invalidPlayers.toString() + "because these players are invalid!");
                        } else if (invalidPlayers.toString() != null && alreadyStalker == null) {
                            player.sendMessage(ChatColor.GREEN + "Removed players that were listed, except" + invalidPlayers.toString() + ",because these players are invalid!");
                        } else if (alreadyStalker.toString() != null && invalidPlayers.toString() == null) {
                            player.sendMessage(ChatColor.GREEN + "Removed players that were listed, except" + alreadyStalker.toString() + ",because these players are already not stalkers!");
                        } else {
                            player.sendMessage(ChatColor.GREEN + "Removed all players successfully!");
                        }

idk why it pasted like that

[drowsy helm]

right

[south onyx]

lemme try again

[lost matrix]

Because you dont respect the character limit

[south onyx]

if (invalidPlayers.toString() != null && alreadyStalker != null) {
                            player.sendMessage(ChatColor.GREEN + "Removed players that were listed, except " + alreadyStalker.toString() + ",because these players are already not stalkers, and also except " + invalidPlayers.toString() + "because these players are invalid!");
                        } else if (invalidPlayers.toString() != null && alreadyStalker == null) {
                            player.sendMessage(ChatColor.GREEN + "Removed players that were listed, except" + invalidPlayers.toString() + ",because these players are invalid!");
                        } else if (alreadyStalker.toString() != null && invalidPlayers.toString() == null) {
                            player.sendMessage(ChatColor.GREEN + "Removed players that were listed, except" + alreadyStalker.toString() + ",because these players are already not stalkers!");
                        } else {
                            player.sendMessage(ChatColor.GREEN + "Removed all players successfully!");
                        }

o

ok anyways

[lost matrix]

If this happens then you need to overthink your design.

[south onyx]

ok

[drowsy helm]

also please change that if statement with getOnlinePlayers()

[south onyx]

ok

[rugged topaz]

    @EventHandler
    public void onTryShoot(EntityShootBowEvent e) {
        if (e.getEntity() instanceof Player) {
            Player p = (Player) e.getEntity();
            e.setCancelled(true);
        }
    }

this takes arrows out of the player's inventory, now instead of just adding an arrow back into it, how do i fix this efficiently?

[lost matrix]

[rugged topaz]

thanks

[lost matrix]

And pls rename your event frome to event
Single character variables are a disease that needs to be stopped.

[rugged topaz]

i'll search and find for my entire project (:

[lost matrix]

Also p -> player

[rugged topaz]

    private void doBlockEater(final Player player, final Block startingBlock, final int amount) {
        if (startingBlock.getType() == Material.AIR) return;

        final Material targetMaterial = startingBlock.getType();
        final ItemStack item = new ItemStack(targetMaterial, 1);
        final ArrayList<Block> blocksToCheck = new ArrayList<>();

        blocksToCheck.add(startingBlock);

        Bukkit.getScheduler().runTaskAsynchronously(getInstance(), () -> {
            while (!blocksToCheck.isEmpty()) {
                int blocksToRemove = 0;
                final Block block = blocksToCheck.get(0);
                blocksToCheck.remove(block);
                if (block.getType() == targetMaterial) {
                    for (final BlockFace blockFace : faces) {
                        blocksToCheck.add(block.getRelative(blockFace));
                    }

                    if (block.getType().name().contains("LOG")) {
                        player.getInventory().addItem(item);
                        block.getWorld().playSound(block.getLocation(), Sound.DIG_WOOD, 0.3F, 2.0F);
                        Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(getInstance(), () -> block.setType(Material.AIR), 3);
                    }
                    blocksToRemove++;
                }
                if (blocksToRemove >= amount) blocksToCheck.clear();
            }
        });
    }

what is effectively wrong with this method of cutting down an entire tree but with an interval of 3 ticks per second of producing an animation of breaking the log block

considering, it used to work better on my old slower system then i upgraded, and it's worse. but even before, it would give me way too many logs filling up my entire inventory after around 20 blocks broken

[sudden raft]

You're scheduling the removal of all the blocks 3 seconds later

I think u want to schedule the removal 3 seconds after the previous removal

[rugged topaz]

yeah

but that wouldn't even answer for the reason why my inventory fills up completely and my ears are bloated with emotion

only from 10 blocks worth of logs

[sudden raft]

Also, you should use a Queue

instead of a list

[rugged topaz]

for the blocksToCheck?

[cerulean harbor]

hi y'all, im completely new to plugin making so excuse the basic question.

so far i have a working command '/power [target]', but right now it's empty and just sends a message to the player. what I want the command to do is store the target player's UUID in an arraylist somewhere that persists through server resets. how would you guys go about this?

[rugged topaz]

through server resets?

[cerulean harbor]

restarts

[rugged topaz]

yes ik

but

[sudden raft]

Queue<Block> blocks = new LinkedList<>();
blocks.add(startingBlock);

int count = 0;
while (!blocks.isEmpty() && count++ < maxRemovedBlocks) {
  Block block = blocks.remove();
   if (block is target) {
         // ... same code you have
   }
    if (is log) {
     
        runLater(plugin, () -> {
              // add item and remove block
        }, count * 60);
    }
}```

[sudden raft]

Yes

[rugged topaz]

arraylists are tied to memory, and memory is reset after /rl, /restart, /stop, the process ceasing to exist blah

you can write it to a file

[sudden raft]

Lemme see the javadocs because i dont remember the method names

[rugged topaz]

and parse that onEnable()

https://www.spigotmc.org/threads/saving-arraylists-in-config.236465/

this'll help you

[cerulean harbor]

ah

thank you

seems like exactly what I need

[rugged topaz]

yessuh

[rugged topaz]

ah i'll try that

and lyk

[cerulean harbor]

@rugged topaz would i just be putting this in my main class? does it matter where?

https://bukkit.org/threads/tutorial-custom-yml-files.259122/

[sudden raft]

what is lyk

[rugged topaz]

let you know

[sudden raft]

ah

[rugged topaz]

for that matter it's preferable that it is in your main class

and if your main class is called Main, Plugin, consider changing it (:

[cerulean harbor]

i was told that naming it main was standard? is there a specific reason

[rugged topaz]

ambiguity

and that's not true

just call it the name of your plugin

    private void doBlockEater(final Player player, final Block startingBlock, final int amount) {
        if (startingBlock.getType() == Material.AIR) return;

        final Material targetMaterial = startingBlock.getType();
        final ItemStack item = new ItemStack(targetMaterial, 1);
        final Queue<Block> blocks = new LinkedList<>();
        blocks.add(startingBlock);

        Bukkit.getScheduler().runTaskAsynchronously(getInstance(), () -> {
            int count = 0;
            while (!blocks.isEmpty() && count++ < amount) {
                Block block = blocks.remove();
                if (block.getType() == targetMaterial) {
                    for (final BlockFace blockFace : faces) {
                        blocks.add(block.getRelative(blockFace));
                    }
                    count++;
                }

                if (block.getType().name().contains("LOG")) {
                    Bukkit.getScheduler().runTaskLaterAsynchronously(getInstance(), () -> {
                        player.getInventory().addItem(item);
                        block.getWorld().playSound(block.getLocation(), Sound.DIG_WOOD, 0.3F, 2.0F);
                        player.playSound(player.getLocation(), Sound.SUCCESSFUL_HIT, 1.0F, 1.8F);
                        givePlayerForagingXP(player);
                        block.setType(Material.AIR);
                    }, 1 * 60);
                }
            }
        });
    }

@sudden raft

how's this

[dusty herald]

Conventional standards are naming your main class something informative

[cerulean harbor]

i see

thank you

[sudden raft]

remove the count++ inside the if

It's already done in the while(...)

[rugged topaz]

whoops

[sudden raft]

Also it's not necessary to run everything asynchronosuly

[dusty herald]

it's not possible to run everything async ;)

Bukkit.getScheduler().runTaskLaterAsynchronously(getInstance(), () -> {
                        player.getInventory().addItem(item);
                        block.getWorld().playSound(block.getLocation(), Sound.DIG_WOOD, 0.3F, 2.0F);
                        player.playSound(player.getLocation(), Sound.SUCCESSFUL_HIT, 1.0F, 1.8F);
                        givePlayerForagingXP(player);
                        block.setType(Material.AIR);``` *psst* You shouldn't be messing with the Bukkit API async, this code won't even work

[rugged topaz]

so just

[rugged topaz]

why's that?

[dusty herald]

you're trying to modify the world async

[rugged topaz]

oo oohoohh

[dusty herald]

pretty sure you can't even play sounds async either

[rugged topaz]

i mean

it works

it's just terrible

[dusty herald]

it shouldn't work

[rugged topaz]

if you read above, it literally spams my inventory and ears

nah it worked

[sudden raft]

could it work if u disable the AsyncChecker?

i dont remember the class name hahaha

[dusty herald]

🤷 never tried it

I don't like using async that much, I run everything on the main thread, even Thread.sleep /s

[sudden raft]

🤨

[rugged topaz]

welp

what to do

[dusty herald]

try running it sync

[rugged topaz]

as for the two async's tho, remove the first one? or

[sudden raft]

use runTaskLater instead of runTaskLaterAsynchronously

It shouldnt cause lag

[rugged topaz]

the nested one

or the first

[sudden raft]

the nested

[rugged topaz]

    private void doBlockEater(final Player player, final Block startingBlock, final int amount) {
        if (startingBlock.getType() == Material.AIR) return;

        final Material targetMaterial = startingBlock.getType();
        final ItemStack item = new ItemStack(targetMaterial, 1);
        final Queue<Block> blocks = new LinkedList<>();
        blocks.add(startingBlock);

        Bukkit.getScheduler().runTaskAsynchronously(getInstance(), () -> {
            int count = 0;
            while (!blocks.isEmpty() && count++ < amount) {
                Block block = blocks.remove();
                if (block.getType() == targetMaterial) {
                    for (final BlockFace blockFace : faces) {
                        blocks.add(block.getRelative(blockFace));
                    }
                }

                if (block.getType().name().contains("LOG")) {
                    Bukkit.getScheduler().runTaskLater(getInstance(), () -> {
                        player.getInventory().addItem(item);
                        block.getWorld().playSound(block.getLocation(), Sound.DIG_WOOD, 0.3F, 2.0F);
                        player.playSound(player.getLocation(), Sound.SUCCESSFUL_HIT, 1.0F, 1.8F);
                        givePlayerForagingXP(player);
                        block.setType(Material.AIR);
                    }, amount * 40L); // count * 2 seconds interval
                }
            }
        });
    }

current code

still async huh

[summer scroll]

it's not

[rugged topaz]

haha

for some reason, it only breaks 1 block tho

oh and now

almost a minute later

it's working in pairs of 2 blocks every 2 seconds

almost what it's meant to? but completely broken nonetheless

[sudden raft]

hmm

Oh

Youre using the amount variable

You should use the count

For the delay

[rugged topaz]

oh frick

the timing's heavily inaccurate

idk why we're multiplying count by 2 seconds

if it's meant to be at a 2 second interval per block

or even, 4 ticks

[drowsy helm]

there any methods for getting ping without using nms?

[sudden raft]

i dont think so

[sudden raft]

because the tasks are being scheduled at the same time

so, first block waits 2 seconds to be removed, the next waits 4, and so on

[rugged topaz]

Bukkit.getScheduler().runTaskLater(getInstance(), () -> {
     block.setType(Material.AIR);
     player.getInventory().addItem(item);
     block.getWorld().playSound(block.getLocation(), Sound.DIG_WOOD, 0.3F, 2.0F);
     player.playSound(player.getLocation(), Sound.SUCCESSFUL_HIT, 1.0F, 1.8F);
     givePlayerForagingXP(player);
}, count * 1L); // count * 1 tick per block

fr some reason

this is just too slow

and i'm not sure if that's to do with the fact that it's sync

but probably

@sudden raft

[sudden raft]

slow?

[rugged topaz]

mhm

ikr idk

it shouldn't be count

but i'ma test it with just

1 tick

[lost matrix]

Try this thing

public class BlockEaterTask extends BukkitRunnable {

  private static final EnumSet<BlockFace> DETECTION_FACES = EnumSet.of(
      BlockFace.NORTH,
      BlockFace.SOUTH,
      BlockFace.EAST,
      BlockFace.WEST,
      BlockFace.UP,
      BlockFace.DOWN
  );

  private final int hardCheckLimit;
  private final Set<Block> checkedBlocks;
  private final Queue<Block> blockQueue;
  private final Predicate<Block> filter;
  private final Consumer<Block> action;

  public BlockEaterTask(final Block startBlock, final int hardLimit, final Consumer<Block> action, final Predicate<Block> blockFilter) {
    this.hardCheckLimit = hardLimit;
    this.checkedBlocks = new HashSet<>();
    this.checkedBlocks.add(startBlock);
    this.blockQueue = new ArrayDeque<>();
    this.filter = blockFilter;
    this.action = action;
  }

  @Override
  public void run() {
    if (this.blockQueue.isEmpty() || this.checkedBlocks.size() == this.hardCheckLimit) {
      this.cancel();
      return;
    }
    this.next();
  }

  private void next() {
    final Block nextBlock = this.blockQueue.poll();
    for (final BlockFace face : BlockEaterTask.DETECTION_FACES) {
      final Block surrounding = nextBlock.getRelative(face);
      if (this.checkedBlocks.contains(surrounding)) {
        continue;
      }
      this.checkedBlocks.add(surrounding);
      if (this.filter.test(surrounding)) {
        this.action.accept(surrounding);
        this.blockQueue.add(surrounding);
      }
    }
  }

}

[quaint mantle]

um does EntityDamageByEntityEvent give the kb that the player has recieved ?

[rugged topaz]

i dunno how i'd use that tbh

[rugged topaz]

while (!blocks.isEmpty() && count++ < amount) {
     Bukkit.broadcastMessage(count + "");

printing count immediately sends 35 messages (in my instance) from 0-35, so i'm pretty sure at that point count = 35, which is equal to the amount i pass in

[sudden raft]

Yes it's correct

[rugged topaz]

forsure?

[sudden raft]

yes, read this

[rugged topaz]

mhm ik

but idk why it'd immediately find its way to count = 35 whilst it hasn't broken a single block yet

ahh understand why now

but still undesired result :/

[sudden raft]

how are u calling the method?

[rugged topaz]

blockbreakevent, if the block is equal to type of log, if the player has the intended item in their hand, and if they're in the intended spot, doBlockEater(e.getPlayer(), e.getBlock(), 35)

should be nothing wrong

w that

[sudden raft]

Hmm

[lost matrix]

Example:

  public void destroyStone(final Block startBlock, final JavaPlugin plugin) {
    final BlockEaterTask task = new BlockEaterTask(startBlock, 100, Block::breakNaturally, bl -> bl.getType().equals(Material.STONE));
    task.runTaskTimer(plugin, 1, 1);
  }

[rugged topaz]

i'll try it

[sage swift]

hey you made this for me some months ago, i really appreciate it (especially now when i understand it more, lol)

the block iterator

[lost matrix]

Dont remember ^^ but you are welcome 😄

[sage swift]

#help-development message

[lost matrix]

A i see ^^

[onyx shale]

wut is that a custom break animation?

nvm

its a block remover

[rugged topaz]

        if (this.blockQueue.isEmpty() || this.checkedBlocks.size() == this.hardCheckLimit) {
            Bukkit.broadcastMessage("cancel");
            this.cancel();
            return;
        }

seems like it's always cancelled

isn't blockQueue gonna be empty if it's initalized empty regardless?

[lost matrix]

Uhm. The first block should be inserted in the queue in the beginning.

[rugged topaz]

the starting block is added to checkedBlocks

[lost matrix]

Oh nvm. You need to add that in the constructor

[rugged topaz]

not blockQueue

add wha

starting block to the queue?

[lost matrix]

    this.blockQueue = new ArrayDeque<>();
    this.blockQueue.add(startBlock);

[rugged topaz]

yah

seems like it works fine

just the starting block isn't broken 😝

[lost matrix]

just

    if (blockFilter.test(startBlock)) {
      action.accept(startBlock);
    }

At the end of the constructor. idk

[rugged topaz]

that fixed it

but i needa perform multiple things at once,
is it possible to pass that in as a parameter instead of this final Consumer<Block> action?

rather not just cheat it into the actual class

like a lambda of code

[lost matrix]

Sure. This here would grow all the connected wheat to max age:

  public void growWheat(final Block startBlock, final JavaPlugin plugin) {
    final BlockEaterTask task = new BlockEaterTask(startBlock, 100, this::growBlock, this::isViableBlock);
    task.runTaskTimer(plugin, 1, 1);
  }

  private boolean isViableBlock(final Block block) {
    return block.getType() == Material.WHEAT;
  }

  private void growBlock(final Block block) {
    final BlockData data = block.getBlockData();
    if (data instanceof Ageable) {
      final Ageable ageable = (Ageable) data;
      ageable.setAge(ageable.getMaximumAge());
    }
    block.setBlockData(data);
  }

[kind coral]

how would i round up a number to a multiple of 9? i am making a InventoryLib

[lost matrix]

Wait...

[lost matrix]

This looks like it should work:

  public static int roundUp(final int number, final int base) {
    return (Math.floorDiv(number - 1, base) + 1) * base;
  }

Now it works...

Just not for 0

how to create custom achievement popups?

[severe zenith]

i dont understand exactly how to spcify the reciever player

[quaint mantle]

what are u trying to do?

[severe zenith]

understand plugin messaging

[quaint mantle]

yea i got it but i mean like are u trying to do (Connect, IP, IPother etc.)

[severe zenith]

nothing yet. i just want to know how it works

[quaint mantle]

u just send messages between spigot and proxy

[severe zenith]

yeah: for example Connect

[quaint mantle]

like connect u send player to server

lemme send u example

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

[severe zenith]

ok, the channel is "BungeeCord", the subchannel is "Connect", the argument is "", and the reciever is player???

@quaint mantle is this correct?

[quaint mantle]

yes

[severe zenith]

ok, thanks

[quaint mantle]

like you write into the argument something like i said for ex. Lobby, Auth

like name of server when u use Connect

Hey! I saw you were interested in our Java Project of working with the SpigotAPI.

This is a long-term project. We have a current open project of about one year of work. Here is the plugin we are currently working on:
https://docs.google.com/document/d/1wKi4Cr7dHou1JZFjqPwi2GBE-WLGEhF5XYXtWguYlXA/edit

This is also a well-paying and loyal position.
I have a few question, it is okay to be honest, as we are hiring several developers who are interested in this position long-term.

Do you have any experience with SpigotAPI?

Have you played Minecraft?

Could you learn the SpigotAPI?

Do you have experience working in gradle?

What interests you about this job and why do you want this project?

This is just to get an understanding so we can work better together! :D

That's is what am looking for

1. You are asking for services in #help-development

[quaint mantle]

why would you apply for spigot developing when you dont know spigotapi

[median plank]

Am newbie

[quiet ice]

2. You are asking for server help in #help-development

[median plank]

I want to start

[quiet ice]

3. This is not how you hire people

[quaint mantle]

you want to start with what?

[eternal oxide]

How to write Spigot plugins - https://www.spigotmc.org/wiki/spigot-plugin-development/

[quiet ice]

Meh, that is a bad one

[quaint mantle]

well first of all if you dont know java u should learn it first before working with apis and stuff

[quiet ice]

https://bukkit.fandom.com/wiki/Plugin_Tutorial_(Eclipse) is a better one

Granted, it is outdated but it does a lot more right

[eternal oxide]

It looks decent

I link the other as it covers more IDEs and should be all anyone needs.

Hi hi, i'm trying to get a config.yml file for bungeecord and I used this example https://www.spigotmc.org/threads/bungeecords-configuration-api.11214/
I get a null pointer error in this line: Files.copy(in, file.toPath());
full method:

    private void saveDefaultConfig() {
        if (!getDataFolder().exists())
            getDataFolder().mkdir();
        File file = new File(getDataFolder(), "config.yml");
        if (!file.exists()) {
            try (InputStream in = getResourceAsStream("config.yml")) {
                Files.copy(in, file.toPath());
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

Full class (and yes, I know bungeecord already sends a startup message for the plugin)
https://pastebin.com/nwewHt4P

Can anyone explain what i'n doing wrong?

oh and the error

[eternal oxide]

BungeeMain.java:51

[eternal oxide]

either in or file is null

[toxic mesa]

Alrighty ill mess around with it

[eternal oxide]

Why not just use the provided saveResource method?

ah Bungee

[toxic mesa]

yep

And #getResourceAsStream was indeed null, and i found this fourm post https://www.spigotmc.org/threads/getting-file-as-inputstream-within-the-jar.405681/
And tried what they said:

        this.getClass().getClassLoader();
    try (InputStream in = ClassLoader.getSystemResourceAsStream("config.yml")) {

however this still returns null

[quiet ice]

Use Java 15+ and you wouldn't be in here anyways

[toxic mesa]

o

[quiet ice]

The more descriptive Null Pointer Exception messages are really worth to get Java 15+

[ivory sleet]

Objects#requireNonNull(obj,str) 🤡

[quiet ice]

Why not use Plugin#getResourceAsStream?

Or whatever it is called

[toxic mesa]

this forum post

I had that before, but it was null

So i googled and got that forum

[eternal oxide]

Are you trying to save the default Bungee config for your plugin?

[toxic mesa]

yup

[eternal oxide]

thats not how you do it..sec

https://www.spigotmc.org/wiki/using-the-bungee-configuration-system/

followed that?

[toxic mesa]

Jup

[toxic mesa]

.

null error

[eternal oxide]

If you have then you are missing the config.yml in your plugin jar

[toxic mesa]

thats

o

yeah

shit

m b

god dammit

[eternal oxide]

happens to everyone at some point 🙂

[severe zenith]

Ok, I now understood how to send messages from a spigot plugin to the bungeecord system and how to recieve responses. But how to send messages from Bungeecord to Spigot and how to recieve messages on Bungeecord?

[ivory sleet]

Check the plugin message channel API in bungee javadoc but presumably you’d do smtng very similar to what is done in spigot API

[slim magnet]

What's the difference between InventoryInteractEvent and InventoryClickEvent? (In terms of making GUI menus)

[eternal oxide]

Interact is an abstact event thats used as a base for other Inventory events. It will not be fired itself.

[slim magnet]

Can I still listen to it tho?

Should I handle interact or click?

[eternal oxide]

As I just said, interact will never fire. Its an abstract class

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/InventoryInteractEvent.html

look at its subclasses for those that you can listen for

[tame iron]

hi! there is a task to get chunks in a certain radius from the player, how can this be implemented?

[eternal oxide]

Explain what you mean by "get chunks"

[tame iron]

the player specifies the value in chunks with the command and I need to get all chunks in this radius getChunk()

[ivory sleet]

InventoryInteractEvent wont ever fire it's mainly used for inheritance and convenience

[rapid vigil]

Hey, is there anyway to do so everytime someone dies it comes up with different death message?

Like different death message everytime

[ivory sleet]

yeah

[rapid vigil]

I tried multiple ways but none worked

I made 6 classes, and each one has a different death message

But It's 1 same message from them and it never changes

[eternal oxide]

The reason I ask is teh implementation greatly depends on what you need it for. What do you need the chunks for? To store them, or what?

[stone sinew]

Show the code. Debug the code.

[rapid vigil]

First class :

    public void onDeath(PlayerDeathEvent e) {
        if (e.getEntity().getKiller() instanceof Player) {
            Player k = e.getEntity().getKiller();
            Player v = e.getEntity();
            e.setDeathMessage("§6§l" + v.getName() + "§6 was slain by §l" + k.getName);
        }
    }
}```

[ivory sleet]

class PogConclure implements Listener {
  String[] messages = new String[]{"first", "second"};

  @EventHandler public void onDeath(EntityDeathEvent event) {
    if(event.getEntity().getType() != EntityType.PLAYER) return;

    Bukkit.broadcastMessage(messages[ThreadLocalRandom.current().nextInt(messages.length)]);
  }
}``` @rapid vigil

[rapid vigil]

And same thing with other classes, but different death message

[tame iron]

creating territory protection
claim.isNewRegion(chunk);

[stone sinew]

Debug. Are the listeners even running?

[ivory sleet]

oh yeha you might wanna set it instead

[rapid vigil]

Thanks Conclure. Appreciate it

[eternal oxide]

take the players location (x,z) / 16 will give you the chunk.
Add half the players given value to get max, minus half to get minimun.

its just two loops then to grab all chunks

[eternal oxide]

public class RandomDeath {

  final static String[] message = new String[] { "You died!", "Fatality", "Poor you" };
  final static random = new Random();

  public static String getMessage() {
    return message[random.nextInt(message.length)];
  }
}```

[rapid vigil]

What's wrong with Conclure's code though?

[eternal oxide]

Nothing. I didn't see it. Both are just as valid

[rapid vigil]

Thanks a lot appreciate it anyways ;)

[eternal oxide]

Not sure what you are asking

[minor garnet]

translator bad

[eternal oxide]

You want the block the player is looking at?

[minor garnet]

no

location of cross hair

[eternal oxide]

the cross hair is only on the client. It represents nothing on the server

[minor garnet]

no i mean

when you right-click on the block, you have the location of the block, I wanted the location of the crosshairs on the block

[eternal oxide]

There is a method but I forget what it called. sec

[minor garnet]

i forgot, i'm on 1.8

[eternal oxide]

ok, not helping with that

[languid geode]

Lads what in the hell did you guys do the the project structure of craftbukkit all my branches are no longer compilable

[eternal oxide]

Nothing

[languid geode]

@eternal oxide Well Something happened to all my NMS patches none of them are able to apply anymore

Also for some reason my project is unable to import any of the classes in the same package

[willow fossil]

Can i set more then one Item in an Inventory in one Code Line?

[eternal oxide]

Sounds like you need to clean/invalidate cache on your project

[minor garnet]

i had an idea, using the direction of the player I could multiply with the distance of the block

and get a location by this vector

[languid geode]

Actually a good idea

Still wont fix all my patch files tho but still

ill redo the changes on those because merging patch files is a pain in the first place

[languid geode]

Thank you that actually worked to my surprise

[cold field]

Hi guys, can some explain me what dataWatcher is used for?

[languid geode]

To watch data changes

data-watcher

[cold field]

Lol, ok

More in-depth?

[willow fossil]

Can i set more then one Item in an Inventory in one Code Line?

[languid geode]

Think events for variables

[cold field]

so, when a variable changes it executes code, right?

[languid geode]

correct

[cold field]

setContents()

[languid geode]

@eternal oxide Could you help with my patch files ever since we decided to change all of the paths for them none of them work for me anymore and i cant get my root fixed due to that fact

[drowsy helm]

No but you can make a helper method for it

[eternal oxide]

I've not done any patches.

[languid geode]

Well darn guess i just nuke my changes and rebuilt them from the ground up

[drowsy helm]

Probs have to move em manually

[cold field]

Does anyone know what it is the variable "a" inside the DataWatcherObject class?

[eternal night]

I believe that would be the data value id

basically an integer identifier of the data that is stored in the object
