[twilit wharf]

wait, nevermind

it is the first thing being set on onEnable

[tawny horizon]

hm,m

does Started scheduled task ever print?

[rough jay]

can this

for (int i = 0; i < players.size(); i++) {
    if (players.get(i).equals(player.getName())) {
        players.remove(i);
    }
}

be replaced with this?

players.removeIf(s -> player.getName().equals(s));

[tawny horizon]

what is players?

[twilit wharf]

no

[tawny horizon]

a list i would assume?

[tawny horizon]

send the entire class in a paste

[tawny horizon]

so is players a list?

[rough jay]

yes

[acoustic pendant]

static double Mana = 100;
static double MaxMana = 100;

to separate things like this per players

how am i supposed to do it?

with a hashmap or something like that?

[rough jay]

yes

[tawny horizon]

that should work then

[tawny horizon]

what exactly is this for?

[acoustic pendant]

hmm

i want that players

[rough jay]

Also, will the method always return true/false, or does the return value changes at it should?

private boolean removePlayerFromGroup(YamlConfiguration yaml, OfflinePlayer player, String group) {
    List<String> players = yaml.getStringList(group);
    List<String> newPlayers = players;
    newPlayers.removeIf(s -> player.getName().equals(s));
    yaml.set(group, newPlayers);

    try {
        yaml.save("plugins/MaxiCity/teams.yml");
    } catch (IOException e) {
        e.printStackTrace();
    }

    return players.equals(newPlayers);
}

[acoustic pendant]

store different numbers

they start all with 100

but can change that

[tawny horizon]

What are the numbers for? Are they for each player or the same for everyone?

[acoustic pendant]

each player

[tawny horizon]

that wont work

[rough jay]

yeah ik I'm trying something else now

[tawny horizon]

you need to at the very least replace

newPlayers.removeIf(s -> player.getName().equals(s));

with

newPlayers.removeIf(s -> player.getName().equals(s.getName()));

[rough jay]

boolean flag = players.removeIf(s -> player.getName().equals(s));

If a player's name is removed from players, will flag be true or false?

[tawny horizon]

Is MaxMana the same for everyone or different for everyone?

[acoustic pendant]

i want to be different for everyone

public class perPlayerStats {


    Map<UUID, Double> mana = new HashMap<>();

    public void separateMana(Player player){
        mana.put(player.getUniqueId(), ManaStatMain.MaxMana);
        
    }



}```

trying something like this

[tardy delta]

private brrrr

[tawny horizon]

Then make an object and store it on a static map

[rough jay]

Why? s is a string so s.getName() is... wrong?

[acoustic pendant]

should i do a PlayerJoinEvent so when a player joins he enters the hashmap?

[tardy delta]

ah its a string

[tawny horizon]

Wait, if I may ask why is the players list strings?..

[rough jay]

Here's how it's done

private boolean removePlayerFromGroup(YamlConfiguration yaml, OfflinePlayer player, String group) {
    List<String> players = yaml.getStringList(group);
    boolean flag = players.removeIf(s -> player.getName().equals(s));
    yaml.set(group, players);

    try {
        yaml.save("plugins/MaxiCity/teams.yml");
    } catch (IOException e) {
        e.printStackTrace();
    }

    return flag;
}

[rough jay]

Well [Max094_Reikeb, Nat7123, TheFlow] is a list of strings because usernames are strings

[tawny horizon]

Yea thats what I would do, also have a Json file for the data if possible

or YML

[acoustic pendant]

or MySQL?

[tawny horizon]

Ehh, i guess if you have a ton of players then sure

[acoustic pendant]

i will do that

ty!

[tawny horizon]

mhm

[rough jay]

@tawny horizon am I all good? https://pastebin.com/kq1nvvgg

[quaint mantle]

These perms are automatically set to default: op? (names are just for example)

[opal juniper]

no

[quaint mantle]

ok

[opal juniper]

you must declare them as well

[quaint mantle]

ok, thanks

[twilit wharf]

https://paste.md-5.net/vuyekowohu.cs @tawny horizon

[tawny horizon]

I would recommend storing groups in data files and loading them on the plugin enable and storing them in a hashmap

Here is how I would recommend doing it.

public class Group {

    @Getter
    private final static HashSet<Group> allGroups = new HashSet()<>;

    @Getter
    private final HashSet<UUID> playersList = new HashSet()<>;

    @Getter
    private final String groupName;

    public Group(String groupName) {
        this.groupName = groupName;
        allGroups.add(this);
    }

    public void addPlayerToGroup(UUID playerUUID) {
        playersList.add(playerUUID);
    }

    public void removePlayerToGroup(UUID playerUUID) {
        playersList.remove(playerUUID);
    }
}

something like that

You could also make a HashMap with every UUID and their corresponding group for quick checking on that

that way you dont have to load a YML file every time you need to add / remove someone from a group

just save the file every 5min or so

and onDisable()

[rough jay]

It's already a thing

[tawny horizon]

Then how come the code for adding and removing players requires the file?

[rough jay]

HashMap manager

https://github.com/Max094Reikeb/MaxiCity/blob/master/src/net/reikeb/maxicity/datas/PlayerManager.java

[tawny horizon]

and permissions

[rough jay]

And Group enum : https://github.com/Max094Reikeb/MaxiCity/blob/master/src/net/reikeb/maxicity/datas/Group.java

I haven't really tested perms but the playerDataMap works fine and is saved

[twilit wharf]

might have something to do with the delay, idk

[tawny horizon]

Sysout something to do with the instance just to see if it is null

for whatever reason

[rough jay]

@tawny horizon

1. When player connects, it checks in the team.yml file to see in what Group the player is.
   https://github.com/Max094Reikeb/MaxiCity/blob/master/src/net/reikeb/maxicity/listeners/players/JoinQuit.java#L90
2. The PlayerManager adds permissions to the player depending on the Group he is
   https://github.com/Max094Reikeb/MaxiCity/blob/master/src/net/reikeb/maxicity/datas/PlayerManager.java#L56

[tawny horizon]

Thats what Im saying, it would be more efficient to just have all of that data stored on a hashmap so that you dont have to check the file with every player that logs in

the file would be scanned once

[rough jay]

you can't only scan the file once

what if it gets changed?

[twilit wharf]

it prints a blank line

[tawny horizon]

The only way the file should be changed is through your code

[tawny horizon]

do System.out.println("This is the instance: " + instance);

[rough jay]

well no because if an admin has an access to the file then he can change it. I know people like us would know to only change the file via code (the command I made earlier) but for some people it's not that clear, and I need to make the code "break-proof"

[twilit wharf]

it prints this: This is the instance: APOC-WorldControl v1.2.472

[tawny horizon]

Then make it impossible to change any way other than through your own code, accessing the file with every login is just so slow that its not reasonable to do.

[tawny horizon]

Ok, so its not null.

hmm

[lean gull]

does anyone have a good tutorial for a tab plugin with a config file? i want to make a plugin that has its own yml file, and in that file there's a header section and a footer section, and you can change like 5 lines of each section, and also have like the player ping, server tps, etc etc

[twilit wharf]

I believe Kody Simpson has a very detailed tutorial on this.

look him up on YouTube

[lean gull]

don't see one

[twilit wharf]

oh, then idk

[tawny horizon]

@rough jay should players be allowed to be in more than one group at once?

[twilit wharf]

maybe there is a better way to do it than a Bukkit schedule delay? all i want is to wait 5 min and try again, over and over, without stopping everything else

[rough jay]

they can yeah

[tawny horizon]

?paste

[undone axle]

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

[tawny horizon]

If you want I wrote this really quick, you could check it for bugs but i doubt there are any. https://paste.md-5.net/lujumuxari.java

It would handle all of the logic of taking care of groups and checking who is in what group, saving data, and so on.

Note: The "saveAllData()" method needs you yo actually write the config.save() method at the bottom of it (accidently left it out). Also feel free to make the groups non-case sensitive (i just made it case sensitive by defualt)

Also, it would mean they dont have to add permissions for groups

[quaint mantle]

add entity to the team and set the color's team to glow color you want]

[quaint mantle]

eh static

[tawny horizon]

?

[ivory sleet]

they probably said ew because that class is not unit testable and quite rigorously written Ig but its probably fine concerning this isnt some sort of enterprise

[rough jay]

Could you tell me, based on my Github, what part of my code does yours replace?

[tardy delta]

is there a way to keep fly when changing gamemode to survival?

[tacit drift]

setAllowFlying true

or something like that

and setFlying true

[glossy venture]

i think you can just set someone flying

Player#setFlying(true)

i believe

[glossy venture]

maybe this is needed too

lemme check docs

[tacit drift]

that it's like creative fly

[glossy venture]

Player.setAllowFlight(true);
Player.setFlying(true);

like that

[tawny horizon]

It would mainly be used for replacing adding and removing players from groups

in a more efficient way

[glossy venture]

new HashSet()<>
``` wait is this possible?

no

[rough jay]

I don't understand like 90% of the code @tawny horizon

[quaint mantle]

i mean, static having mutable state is not cool and that breaks single responsibility principes. Group shouldnt add itself to the list, thats a task for another object

[rough jay]

like why does addPlayerToGroup only take a Player as parameter? the method is not named correctly then

[tardy delta]

well yea doest work

@EventHandler
    public void onGamemodeChange(PlayerGameModeChangeEvent event) {
        Player player = event.getPlayer();
        if (CommandFly.getFlyingPlayers().contains(player.getUniqueId())
            && event.getNewGameMode() == GameMode.SURVIVAL)
            player.setAllowFlight(true);
    }

[glossy venture]

it stores the groups mapped by name and by UUID in the concurrent maps

[tawny horizon]

Because you use UUID not the Player object itself for a group list

[shrewd hemlock]

is there a way to detect when a player touch the ground?

[glossy venture]

because CommandFly.getFlyingPlayers() doesnt include them maybe?

it should work

so then the statement is not reached

[rough jay]

yes but if I do

addPlayerToGroup(player.getUniqueID());

to what group will player be added in?

[glossy venture]

also you might have to do player.setFlying(true) after it

idk

[tawny horizon]

The group object in which you are calling that method from..

[glossy venture]

its an instance method

so to the group

it adds the player to the group

public void
``` no static

[tawny horizon]

Soooo what part of that breaks the functionality of the class XD

[ivory sleet]

Idk

I mean srp just states classes should only change for one major reason

[quaint mantle]

https://www.toptal.com/developers/hastebin/ijameguzap.csharp

who is toptal

[rough jay]

yeah so how do you register a new group and all?

[glossy venture]

idk

i didnt write it

as dianaa

[tawny horizon]

Here is the thing, using 2 classes for handling groups vs 1 single class makes it more confusing for someone who is new to use, the purpose of me writing that was to make it as easy as possible to use

[tawny horizon]

its automatically done

when you create the instance

[ivory sleet]

how does it make it more confusing

[rough jay]

so if I have 6 groups I need 6 instances?

[glossy venture]

when you do new Group("name")

[glossy venture]

yes

[tawny horizon]

exactly

[tawny horizon]

Because its extra steps

[ivory sleet]

extra steps doesnt mean something is inherently more confusing

[tawny horizon]

Its more to keep track of

[ivory sleet]

No it’s less to keep track of

If you have isolated responsibilities in different classes then you have reduced the amount of complexity in each class as opposed to just using one single class

[tawny horizon]

The way in which it was made literally all he had to do was instance the class for every new group and then add players

calling the load method in onEnable

and save method every 5min or so and once in onDisable

[rough jay]

so it means I replace my enum Group with your class?

[tawny horizon]

Its meant to replace anywhere in which you would be using a group

[rough jay]

I still don't get how is your way better... my enum is good, I don't have to register anything because it's static

[ivory sleet]

Which is bad

[lean gull]

can anyone help? i'm using a config manager and it tells console that it couldn't create the file, it also says that it reloaded it and saved it, but it actually did create the file but did not set anything inside it?
config manager class: https://paste.md-5.net/sijoruluzu.java
main class: https://paste.md-5.net/ariyuwamew.java
class where its supposed to set something in the file: https://paste.md-5.net/bajumulaye.cpp

[tawny horizon]

You can use yours, all I am saying is at the very least you shouldnt be accessing the file every time a player logs in

thats why I wrote that, it does it once when the server loads

and thats about it other than saving

[rough jay]

well no because with their code, I have more HashMaps which means more data to save.
I already have a HashMap for each player with datas of other things in my plugin and when a player has a Group, his group is stored in the HashMap

aaaah

[rough jay]

the file has nothing to do with the Group

[ivory sleet]

More HashMaps doesn’t even imply it’s more data to save necessarily

[tawny horizon]

The data load and save method is already written XD

other than one line on the save method where you have to just type config.save(file)

at the bottom of the method

only one of the maps has anything saved from it at all

[rough jay]

well no because if I use your code, I would still load the file each time a player connects and use the method to load the data or something like that

[tawny horizon]

the other maps are used to make accessing data in the class easier

[tawny horizon]

You wouldnt have to load it every time a player connects, you would just add them to a group

and then save it onDisable

the file would not need to be touched

[rough jay]

well if someone changes the file

[quaint mantle]

I think you can just make a hashmap contains a uuid and another hashmap for that?

Hashmap contains another hashmap i mean

[tawny horizon]

If someone touches and changes a data file thats their fault XD

those are never meant to be edited any way other than through code

[rough jay]

HashMapCeption?

😂

[rough jay]

then what's the point of storing it in an editable separated file if not meant to be edited?
EDIT: edited other than code

[quaint mantle]

Sorry i don’t understand what you mean lel…?

[tawny horizon]

for saving the data through server reloads, thats the only point of the file

[rough jay]

Haven't you seen Inception?

It's a dream inside of a dream

so HashMap inside of HashMap would be HashMapCeption (it's a joke)

[quaint mantle]

Joje

Jole

[rough jay]

joke 😂

[left swift]

how can i make an entityarmorstand that has something similar to noclip? I would like to give it velocity, but when it's in a block it gets stuck

[quaint mantle]

Give it a hacked client then…

Or just see some hacked client source then…

Hacked clients are mods

and im sure it works completely differently since its on client-side

[foggy estuary]

does anyone know how to add players to a scoreboard

[quaint mantle]

also i've never saw a cheat with noclip for mc lol

[opal juniper]

its the other way around i think

you add a scoreboard to a player

[left swift]

what? I want to move armorstand in blocks but currently blocks stop it

[opal juniper]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#setScoreboard(org.bukkit.scoreboard.Scoreboard)

[quaint mantle]

You can try teleporting it through

Probably the best it's going to get

[tardy delta]

whats the best way of saving namespacedkeys?

[ivory sleet]

Like persistently?

[tardy delta]

i was thinking of storing them in a class

[ivory sleet]

Oh I just have a soft cache for it sort of

[left swift]

imo teleport isn't the best way for me, because i want to simulate natural mob movement with velocity, i tried with noGravity and setMarker method for armorstand, but then all velocity is removed

[chrome beacon]

You will have to mess with NMS

Create your own entity and override the collision detection

[quaint mantle]

wdym by saving

toString and fromString?

[tardy delta]

@paper viper said me to

.

[paper viper]

Singleton

[eternal oxide]

NamespacedKeys are just strings

[lean gull]

someone pls help

[foggy estuary]

    //The scoreboard display
    public void OnJoin(PlayerJoinEvent event) {
        createBoard(event.getPlayer());
    }
    
    public void createBoard(Player player) {
        
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        Scoreboard board = manager.getNewScoreboard();
        Objective obj = board.registerNewObjective("test", "dummy",(ChatColor.GOLD + "Bank Heist"));
        
        obj.setDisplaySlot(DisplaySlot.SIDEBAR);
        Score score = obj.getScore(ChatColor.RED+ "Most Gold Collected:");
        score.setScore(3);
        obj.getScore(ChatColor.RED + "Most Gold");
        score.setScore(2);
        obj.getScore(ChatColor.RED + "Time Left");
        score.setScore(1);
        player.setScoreboard(board); ``` Can you explain how i would do it i cant find anything to do it.

[quaint mantle]

private final NamespacedKey xKey, yKey, zKey...

no magic

https://github.com/decalium/persistent-data-types/blob/master/src/main/java/com/manya/pdc/LocationDataType.java

[ivory sleet]

Used to have a class called NamespacedKeyProvider which encapsulated a Map<String,SoftReference<NamespacedKey>> then whenever I needed a key I checked if that key existed within the map, if not then I created a new one and stored it in the map.

[quaint mantle]

but why

i dont think creating a namespacedkey that expensive

[ivory sleet]

Because I had around 2000 keys

so if it was urgently needed, it would go ahead and gc unused ones given that they weren’t used anywhere else (softly reachable)

[left swift]

what is te best way to add to armorstand natural mob movement (like a pig etc.)

[quaint mantle]

i've already answered 😦

[left swift]

I'm looking for different ways

but actually I have a question for you 😄

when i spawn that nms pig, and nms armorstand then it doesn't have any movement, how can i fix that?

[quaint mantle]

show the code

[left swift]

        EntityPig entityPig = new EntityPig(EntityTypes.an, ((CraftWorld) location.getWorld()).getHandle());
        this.ID = entityPig.getId();
        entityPig.setPosition(location.getX(), location.getY(), location.getZ());

        PacketPlayOutSpawnEntityLiving spawnEntityPig = new PacketPlayOutSpawnEntityLiving(entityPig);
        PacketPlayOutEntityDestroy destroyEntityPig = new PacketPlayOutEntityDestroy(ID);

        PacketPlayOutSpawnEntity spawnEntity = new PacketPlayOutSpawnEntity(ID, entityPig.getUniqueID(), location.getX(), location.getY(), location.getZ(), entityPig.getXRot(), entityPig.getYRot(), EntityTypes.c, 0, entityPig.getMot());


        sendPackets(spawnEntityPig, destroyEntityPig, spawnEntity);```

[quaint mantle]

you spawn the pig using api, not packets

[left swift]

I do not understand 😕

[tardy delta]

world.spawnEntity(EntityType.Pig) or something

[paper viper]

why are you using packets

[glossy venture]

there should be a method for spawning entities in an nms world

[left swift]

I'm a beginner, shouldn't I use them?

[hybrid spoke]

depends on what you are trying to do

[quaint mantle]

as i can understand, he wants to make armorstand act like a pig

[left swift]

armorstand with natural mob movement

[quaint mantle]

i thought the easiest way of doing it was replacing pig with armor stand via packets, like LibsDisguises does

[glossy venture]

if you dont want the pig shown dont send packets

[quaint mantle]

1. Spawn a pig with api
2. Destroy it using packets
3. Spawn an armorstand with same entity id as pig using packets

[glossy venture]

do you mean destroy it on clients using packets?

[quaint mantle]

yes

[glossy venture]

but then the entity id is still taken

on the server

[quaint mantle]

we dont need a new entity on the server

[glossy venture]

oh you mean armor stand on client

using packets

[left swift]

Works! thx manya!

is it possible to edit this armorstand? hand movement, adding items etc?

[quaint mantle]

that easy? glad to help!

[quaint mantle]

yes, with metadata packet iirc

[left swift]

ok, and is it possible to change the Y pos of the armorstand?
I mean armorstand go into the ground

[azure nova]

hello! I want to update a scoreboard every 5 seconds, I have read about Runnable and stuff like that, but it's still really confusing for me...All i want is just mere hints, of how do I do it 🥺 , like PROBABLY for no lags, I think updating the scoreboard asnyc would be a good idea? and cause if I update a scoreboard every 5 seconds on main thread, wont that cause lag? cause it wont be just updating a scoreboard but also displaying it on the player screen, right....right?

[eternal oxide]

?scheduling Don;t do it async

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[graceful turret]

how to get material from numeric ID i mean for example stone = 1, air = 0 etc.

[eternal oxide]

We don't use magic numbers any longer

[tardy delta]

btw my actionbar for every player who joins the server is async, is that a good way or not?

[eternal oxide]

Yes its fine. But for someone who is unsure of how to use a Runnable its not.

[quaint mantle]

yes sending messages async is fine

(unless you start an async thread everytime you send it)

[pearl sparrow]

Hello everyone, is there a way of programmatically turning on and off a core shader that is within a resource pack? I am referring to core shaders that were added recently.

[tardy delta]

i have it like in the playerjoinevent new ActionBar.runTaskAsync(blablalbla)

[quaint mantle]

looks fine

[tardy delta]

ki

[quaint mantle]

idk if player.getHealth is a problem

[tardy delta]

getHealthScale does also exist but i dunno what it does

it works so i dont care

uhh

[quaint mantle]

getInstance 😒

[tardy delta]

that runs it immediatly when creating it

nvm

it looks kinda the same

but why not extending runnable?

[quaint mantle]

bruh i use constructors

[quaint mantle]

this staff may lead to the memory leak, you shouldnt use direct Player references

i guess just cancel a task when player leaves

[tardy delta]

wdym? cant i use a player object?

[eternal oxide]

a Player object may go stale

[opal juniper]

what he said

[eternal oxide]

a UUID will not

[tardy delta]

but i need to send an actionbar so i need an player object

[eternal oxide]

get teh player object when you need it

[quaint mantle]

but it seems unecessary to do uuid lookup everytime

[eternal oxide]

I guess it depends on how often you need it and how reliably you are dropping the player reference when teh player leaves

[tardy delta]

i dont completely understand

[quaint mantle]

ElgarL, do you write "teh" on purpose?

[eternal oxide]

no

[ivory sleet]

Ofc you can, but the Player interface and its implementation wasn’t created to be a key for maps nor stored, though it does support HashMaps by implementing hashCode and equals. Ideally it’s just a context object really.

[elfin talon]

Hey if I want to work with Craftserver etc.. Do I have to add the complete Spigot version as an external libary or is there an alternative?

I want to spawn npcs

?

[ivory sleet]

yeah

you'd have to add the actual server jar itself to your compile classpath

[ivory sleet]

for this maybe use citizens or something?

[tardy delta]

and what should i do instead?

athough i dont see a map here

[ivory sleet]

I'd say UUID, it's resistant against invalid Player instances or whatever else you might encounter

[tardy delta]

i need to call player.spigot() every time when updating the actionbar so why would i choose for an uuid where i need to call Bukkit.getPlayer(uuid) every time?

[mighty burrow]

could someone help me with the vault api? I've got essentials installed as well as vault. it logs [Vault] [Economy] Essentials Economy hooked.. however, when i try to get the service using Bukkit.getServer().getServicesManager().getRegistration(Economy.class), it just returns null

[ivory sleet]

Idk the very case here, but yes the drawback of using UUID is that we have to rely on looking up Player by UUID, which in some cases might be redundant if you can assert that the object which strongly references the player is only used during the player's valid session. If you are not sure, and you don't want to use Server::getPlayer then maybe go with a WeakReference<Player> which won't stop the player object to get gc'd.

[mighty burrow]

public static boolean doServiceChecks() {
        
        if (Bukkit.getPluginManager().getPlugin("Vault") == null)
            return false;
            
        if (!Bukkit.getPluginManager().getPlugin("Vault").isEnabled())
            return false;
            
        if (!Main.getPlugin().getClanConfiguration().isVaultEnabled())
            return false;
 
            
        if (service == null)
            service = Bukkit.getServer().getServicesManager().getRegistration(Economy.class);
 
        System.out.println(service == null ? "service is null" : service.toString());

        if (service == null)
            return false;
             

        return true;
    }

it prints service is null everytime

[ivory sleet]

when do you call that method?

[mighty burrow]

so, i have another package which is discord bot code, i call this static method from a command executor for the bot

 @Override
    public void execute(Message msg, ArrayList<String> args) {
        if (args.size() <= 0) {

heres that if required

[tardy delta]

i dont even knows what happens when the player leaves the server

it keeps running guess

no errors

[quaint mantle]

How do you think, is making Clans immutable a good idea? Clan has methods to set display name, add and remove members and homes. the problem is that with immutability i'd have to re-add a clan to the clan manager everytime when i change the clan

[ivory sleet]

anyways point is, for that former code to work, vault must be loaded before you call that method and that also means vault needs to be present in the first place and that you need an economy provider

[ivory sleet]

well you do need to cancel the task?

[ivory sleet]

Hmm I'd say keeping it mutable sounds logical since by your explanation, it sounds like it contains a decent amount of state

[mighty burrow]

i do have both the vault and EssentialsX-2.19.0 plugins. vault even logs this: [Vault] [Economy] Essentials Economy hooked . about vault not being loaded, it passes through the initial checks right?

if (Bukkit.getPluginManager().getPlugin("Vault") == null)
            return false;
            
        if (!Bukkit.getPluginManager().getPlugin("Vault").isEnabled())
            return false;
            
        if (!Main.getPlugin().getClanConfiguration().isVaultEnabled())
            return false;

or does this not ensure that it is loaded? if so, how can i do that

[ivory sleet]

Though Idk if you deal with some sort of multithreaded system here, in that case maybe having it immutable could make it automatically thread safe (apart from the manager)

[quaint mantle]

no, not really. Just thinking about immutability design overall

adventure looks sexy

[ivory sleet]

Yeah lol, though some of adventure is just "virtually immutable"

[ivory sleet]

have you debugged?

(with for instance printing to sysout)

[mighty burrow]

yea theres a println here right

it logs service is null

[tardy delta]

yesh so probably re-designing that actionbar class

[ivory sleet]

thats once

Rohith you probably want to print for every branch

(every if statement)

[mighty burrow]

everytime i run the -bal command from discord, it prints that

[ivory sleet]

to see where exactly it stops

[mighty burrow]

oh,

ublic static boolean doServiceChecks() {
        
        if (Bukkit.getPluginManager().getPlugin("Vault") == null)
            return false;
            
        if (!Bukkit.getPluginManager().getPlugin("Vault").isEnabled())
            return false;
            
        if (!Main.getPlugin().getClanConfiguration().isVaultEnabled())
            return false;
 
            
        if (service == null)
            service = Bukkit.getServer().getServicesManager().getRegistration(Economy.class);
 
        System.out.println(service == null ? "service is null" : service.toString());

        if (service == null)
            return false;
             

        return true;
    }

[ivory sleet]

yuh

[young knoll]

Did you depend on vault in the plugin.yml

[mighty burrow]

if it prints service is null, that means it doesnt stop at the if statements right?

[tardy delta]

something like this?

[mighty burrow]

main: ---
api-version: 1.16

softdepend: [Vault, Essentials]

isnt it named EssentialsX?

[mighty burrow]

oh

[ivory sleet]

(idk acc)

[mighty burrow]

i'll try that

[ivory sleet]

sure do lol

[mighty burrow]

but see

this method is being called long after the server has loaded

(coz i have to get on discord and type the command)

its still null :/

[tardy delta]

EssentialsX should work i guess

[mighty burrow]

yh im tryin that

[tardy delta]

illegal combination of modifiers static and static :kekw:

[mighty burrow]

aagh ive been on this for a day now

i feel like its something stupid im doing

[tardy delta]

need a static plugin instance only to get its name smh

[young knoll]

Just store the name instead?

[tardy delta]

i only need it once and making a private field for that goes brr

[ivory sleet]

anyways this is what I used to do:

interface EconomyProvider {
  Economy getEconomy();
}
class JavaPluginImpl extends JavaPlugin implements EconomyProvider {
  private Economy economy;

  @Override public void onEnable() {
    this.getServer().getBukkitScheduler().runTask(this,() -> {
      this.economy = this.getServer().getServicesManager().load(Economy.class);
    });  
  }

  @Override public Economy getEconomy() {
    return this.economy;  
  }
}```
Then whenever you need economy thing you pass an instance of EconomyProvider (in my case it was the plugin instance)

[mighty burrow]

hm lemme try that

[eternal oxide]

you'd need a task per player

[opal juniper]

what is this indent lol

all over the place

[quaint mantle]

how do i do that?😅

[eternal oxide]

a HashMap

[quaint mantle]

do i have to use a HashMap for every variable??

[opal juniper]

no

something like

Map<UUID, Integer>

instead of task1

So like

.put(player.getUniqueId(), sched.scheduleSyncRepeatingTask(...));

[quaint mantle]

so instad of task1 = sched.scheduleSyncRepeatingTask(plugin, new Runnable() i do what?

[eternal oxide]

You don;t seem to actually be using teh task ID other than to cancel

use a BukkitRunnable, pass the player to it so it only acts on that specific player, then you can call this.cancel() when finished

you will need to track what players have an active runnable, so you don;t start a second (if thats possible)

[fresh pollen]

is there a resource website or smth for protocol lib examples?

[granite beacon]

is there a way to dynamically change a tasktimer (aside from canceling and creating a new one.)

[quaint mantle]

wdym by dynamically change

[granite beacon]

like changing this bit

https://share.pnsdev.com/mavvmt317bim.png

[quaint mantle]

no not really

[granite beacon]

so best way would just be to cancel the current one and schedule a new one with the new timer?

[quaint mantle]

you may run it every tick and count them by yourself

[granite beacon]

that wouldn't impact performance?

[quaint mantle]

no

[granite beacon]

dope

just to understand it a bit better

why would it not impact performance? is it like subscribing to an event that runs x amount of ticks?

[ivory sleet]

It does impact performance

Because it has to invoke your runnable every tick

But it’s negligible to the extent that it doesn’t impact really

[quaint mantle]

but thats actually nothing

[granite beacon]

so should I just dynamically create the runnable depending on how fast I want to run it (aka if (this) cancel & make new) or do what manya said?

[quaint mantle]

depends

how oftenly does the period change

[granite beacon]

it's based on how many players are using it

so

[ivory sleet]

well

[mortal hare]

mood

https://streamable.com/idzk4q

[granite beacon]

not very very often

but kinda often

[ivory sleet]

You’d basically skip the logical code execution when it’s the wrong tick right?

[quaint mantle]

y-yeah

[ivory sleet]

Yeah then it really doesn’t matter

[granite beacon]

dope

Thanks 🙂

[ivory sleet]

I mean you could re schedule a new task everytime but it comes with some other problems

[granite beacon]

what are they?

[quaint mantle]

thats annoying at the first place isnt it

[granite beacon]

true

[ivory sleet]

For instance you have to keep track of each individual BukkitTask instance which gets created every time. Then it also increments task id tracker unnecessarily.

For the former ofc you don’t have to keep track of them, but you might need it in the future if you want proper cancellation or something

[granite beacon]

I don't think keeping track of them would be an issue but I do see what you mean with the task id. Are there any side effects to that?

(just curious)

[ivory sleet]

No not really

It’s just an AtomicInteger iirc

[patent horizon]

how do i spawn a client sided entity with protocol support?

[mortal hare]

send spawn living entity packet

[ivory sleet]

Probably not an issue for any decent dev but the design would require excessive mutations (which can cause complications for other stuff)

[granite beacon]

very true

[patent horizon]

https://ci.dmulloy2.net/job/ProtocolLib/javadoc/com/comphenix/protocol/PacketType.Play.Client.html#ENTITY_ACTION

doesnt look to be one

[mortal hare]

Its in Play.Server section

[patent horizon]

oh

it's a server thing?

[mortal hare]

well server sends an entity to the client

not the client to the server

[patent horizon]

but i thought the client was per-player and server was global players

why would the server handle an entity only one person's client sees?

[mortal hare]

that's not how servers work. To get clientsided rendering of an entity

server needs to send the packet

to specific player

in order for server to display all entities in the world

it sends packets to player's client every tick

a.k.a 1/20 second

[patent horizon]

ah ok

[mortal hare]

but yes, you can send the packet manually

[patent horizon]

would that mean i need to make a repeated task in order to spawn the entity and then to keep it alive and do things afterwards?

[mortal hare]

no

https://wiki.vg

has you covered for this

[patent horizon]

so i can just spawn a fake entity for the player, and it'll just wander around like normal ai?

[mortal hare]

no it wouldnt

AI pathfinding is controlled by the server

[patent horizon]

ah

[mortal hare]

you're only sending the packet

the incorrect server packet

[patent horizon]

and the entity stays there until updated?

[mortal hare]

client believes it that its from server and its true

client renders it

AI pathfinding system on server, it sends
positions packets back to the client

AI is not done on clientside

you can test that by lagging yourself out in a server

not any mob would move

nor do the sounds

[patent horizon]

right

how would i then remove the entity?

[mortal hare]

you're basically sending data back to the client without server noticing it and verifying it

you're bypassing the whole server processing

For removing entity from the client screen

there's Entity Destroy packet

which when sent deletes mob from player's screen

[patent horizon]

it would just delete it right?

not do the kill animation

[mortal hare]

yes

just poof

and its gone

[patent horizon]

alr that's better in my case

[mortal hare]

In order to do animations

there's separate packet

when player or mob has been killed server sends animation packets back

to inform client that animation needs to be done since on server a entity has died

most of the data about the game is stored on the server

client mostly does the rendering

and positioning

[patent horizon]

so uh in my case, im trying to make it look like a fishing rod is being thrown from a carrot on a stick

https://github.com/Bukkit/mc-dev/blob/master/net/minecraft/server/EntityFishingHook.java

does this packet count as an entity when using the entity spawn packet?

[mortal hare]

it should

https://wiki.vg/

there's a website

which tells you more about minecraft's protocol

go to Current Protocol Specification and see the packet you want for yourself

yes you can spawn fishing hook

by using Spawn Entity packet

im not sure if it includes the rendering of the string

[autumn hound]

is there any way to convert a cachedservericon to a bufferedimage?

[patent horizon]

yeah im not sure where you'd specify the string's owner

in bukkit, you have to specify an owner public EntityFishingHook(World world, EntityHuman entityhuman) {

and i guess they also use the owners facing direction for hook velo and such

[mortal hare]

are you looking into NMS or protocollib

Every entity has its own ID

persistent between client and server

EID

not UUID

[quaint bough]

https://prnt.sc/1you9d8
This method registers goalSelector of entity villager what is the number parameter for this method im not sure what it does

[patent horizon]

that's nms

but i was hoping protocol had support for what i wanted to achieve in nms

maybe i have to specify the owner afterwards or smth

PacketContainer fakeExplosion = protocolManager.
        createPacket(PacketType.Play.Server.EXPLOSION);

fakeExplosion.getDoubles().
    write(0, player.getLocation().getX()).
    write(1, player.getLocation().getY()).
    write(2, player.getLocation().getZ());
fakeExplosion.getFloat().write(0, 3.0F);```
similar to this

[mortal hare]

its a reflection library for packets. it doesnt provide full support for clientside features you need to do it for yourself

im pretty sure I saw on youtube how to spawn fishing hook with string via NMS

[patent horizon]

rlly?

that would be awesome to see

[quaint bough]

seems like the hashmap but the hashmap has Pathfinder items but does the index matter when adding more pathfinder goals?

[mortal hare]

i cant find it

but its at least couple years old

and i think it was german

coding it

[patent horizon]

lmao

[mortal hare]

what he did is he pulled up the fishing rod class

and there's i think a method

to spawn the grappling hook

he just used the reflection to get that private method

and utilised it

[lean gull]

how do i make a custom skull item from nbt? like from the heads db api

[young knoll]

https://www.spigotmc.org/threads/how-to-create-heads-with-custom-base64-texture.352562/

[sharp bough]

tf is this new "theres a better way of doing it " thing

ahahahhaah

theres always a better way of doing anything

[patent horizon]

    public static ItemStack createSkull(String value) {

        String url = "eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUv" + value;

        ItemStack head = new ItemStack(Material.PLAYER_HEAD);
        if (url.isEmpty()) return head;

        SkullMeta headMeta = (SkullMeta) head.getItemMeta();
        GameProfile profile = new GameProfile(UUID.randomUUID(), null);
        profile.getProperties().put("textures", new Property("textures", url));

        try {
            Field profileField = headMeta.getClass().getDeclaredField("profile");
            profileField.setAccessible(true);
            profileField.set(headMeta, profile);
        } catch (IllegalArgumentException | NoSuchFieldException | SecurityException | IllegalAccessException error) {
            error.printStackTrace();
        }
        head.setItemMeta(headMeta);
        return head;
        
    }```

basically go to custom heads website, go all the way down until you see the "value" field and paste that into the parameter for this method

it'll return your head as an itemstack

[vestal matrix]

how to i enable the arms of an armor stand? i dont see anything on the intellij tabcomplete i see stuff like setGravity but nothing for arms or baseplate?

[patent horizon]

those are really more living entity attributes

you have to actually set the nbt of the living entity to show arms

[young knoll]

What, no

[patent horizon]

well idk

oh wait no im dumb

[young knoll]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/ArmorStand.html#setArms(boolean)

[patent horizon]

show arms will be inside of ArmorStand

yeah

[vestal matrix]

Cannot resolve method 'setArms' in 'Entity'

[patent horizon]

read plz

[vestal matrix]

what

[young knoll]

Entity is not armorstand

[vestal matrix]

oh wait i just realised i was using entity instead of armor stand

[patent horizon]

        LivingEntity armorStandEntity = (LivingEntity) Bukkit.getWorld("your_world").spawnEntity(location, EntityType.ARMOR_STAND);
        ArmorStand armorStand = (ArmorStand) armorStandEntity;
        armorStand.setArms(true);```

[vestal matrix]

mb

[patent horizon]

yuppers

actually you can even do

        LivingEntity armorStandEntity = (LivingEntity) Bukkit.getWorld("your_world").spawnEntity(location, EntityType.ARMOR_STAND);
        (ArmorStand) armorStandEntity.setArms(true);```

[vestal matrix]

alright thanks

[patent horizon]

does anyone have an example of sending server nms packets to a player

[young knoll]

Even better,
ArmorStand armorstand = world.spawn(location, ArmorStand.class)

[patent horizon]

Use the remapped jar

Or get used to digging through obfuscated stuff

[formal dome]

what is this plugin object?

plugin.saveDefaultConfig();

[drowsy helm]

your main class which extends JavaPlugin

[formal dome]

i can call it within itself?

[drowsy helm]

yep

[formal dome]

oh ok

[formal dome]

that's not working

[drowsy helm]

show ur code

[formal dome]

public class BroadcastReader extends JavaPlugin implements Listener {

    public File config;
    public Socket clientSocket;
    public PrintWriter out;

    @Override
    public void onEnable() {

        BroadcastReader.getProvidingPlugin().saveDefaultConfig();

        try {
            clientSocket = new Socket("ip", 8080);
            out = new PrintWriter(clientSocket.getOutputStream(), true);
        } catch (IOException e) {
            e.printStackTrace();
        }

        config = new File(getDataFolder(), "src/main/resources/config.yml");
            if(!config.exists()){
                config.getParentFile().mkdirs();
                saveResource("src/main/resources/config.yml", false);
            }

        getServer().getPluginManager().registerEvents(this, this);


    }```

[drowsy helm]

whats the whole BroadcastReader.getProvidingPlugin()

[formal dome]

lmao my first guess at saving a config

[drowsy helm]

saveDefaultConfig() is a method of JavaPlugin

just call it

[formal dome]

it's not static

[drowsy helm]

it doesn't need to be static

[formal dome]

oh

ok

sorry

[drowsy helm]

all you need to do is saveDefaultConfig() i think you're confused that you need an instance reference

[formal dome]

yeah i figured it out lol

[young knoll]

I mean you can use this if you really want to have an instance reference

[formal dome]

nah i don't

i forgot that its inheriting all the methods so i can just call it lol

since it's a function of the class now

question, what's the usual way of updating config files other than manually changnig it

is there a way to do it from the server instance

like an initial setup screen in the server... maybe a slash command that sets it up

[young knoll]

Nope

The usual method is to read the one in the jar and the one on the server, copy any missing fields from jar to server

Of course if you change fields that doesn’t quite work

[autumn hound]

is there any way to convert a cachedservericon to a bufferedimage?

[odd lichen]

Custom enchantments and effects on a pickaxe while player is holding: looping through enchantments on pick and doing ABC...

One repeating task that loops through all players and checks if player is holding certain item and do something
OR
One repeating task per player that does so.

My main concern is with lag spikes when the repeating task is ran, and my thought process is to use per player tasks which means that the tasks are ran at a more sporadic interval.

Any thoughts would be appreciated.

[young knoll]

Depends how frequent it is

[odd lichen]

every 15secs

[young knoll]

A good option is to run a task every say, 3 seconds and process 20% of online players each time

[dry forum]

i have an api in my plugin that uses public classes and voids and all that but how am i supose to let other people use it in their plugin's library? i tried adding it to a new project and i did ApiTest at = new ApiTest(this); and where it says this, it says it needs to be the exact same main path as my api project so lets say in my api class my main class path was com.stuff.main the main path on the other plugin would need to be that as well

[drowsy helm]

did you import the jar

[dry forum]

yeah its added as a library

[drowsy helm]

is your api an actual plugin itself?

[dry forum]

yeah

[drowsy helm]

well you cant instantiate a plugin

you have to have another way to access it

[dry forum]

what

its not on my server or anything im just trying to test the methods in another plugin

[ivory sleet]

An api is just a set of interfaces you internally implement, then you expose them through services manager.

[mortal hare]

what you can do

is to get the plugin instance via pluginmanager

and cast it to the class of library plugin

[quaint mantle]

I've heard there's some sort of service manager in bukkit or smth

[mortal hare]

MyLibrary library = (MyLibrary)server.getPlugin("MyLibrary");

[lost matrix]

Or you just use JavaPlugin#getPlugin(Class<? extends JavaPlugin>)
This way you dont need to cast

[mortal hare]

im surprised that the library doesnt provide a static accessor

or service api

majority of API's on spigot include static getter method to get the instance of the library plugin

iirc WorldGuard or WorldEdit uses service api

[lost matrix]

You need to add it as a library but your must not include it when compiling.

[quaint mantle]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/plugin/ServicesManager.html

[mortal hare]

it only works for some libraries, plugin developer needs to implement the service for himself.

[quaint mantle]

Ah

I thought this guy made his own api

[lost matrix]

Usually the ServicesManager is not needed when providing an API.
Its only useful if you want other devs to provide an implementation for one of your interfaces.
Custom events and simple API classes are more suitable in most cases.

[summer scroll]

Is using abstract/interface class considered as using inheritance concept?

[quaint mantle]

😂

[noble lantern]

For BlockPlaceEvent#getItemInHand()

Is the item in hand the block that was placed? EG: If they place blocks in offhand, it gets the block in the offhand, and if its in main hand it gets it in main hand?

[summer scroll]

Are you trying to add support from 1.8 to latest?

[noble lantern]

1.16+ only

[quaint mantle]

Interfaces are nothing but polymorphism

[noble lantern]

Maybe will do 1.13 but not sure yet

[summer scroll]

Maybe you should use BlockPlaceEvent#getBlockPlaced instead.

[noble lantern]

Maybe i should of added this information:

I want to find how many items the player has in theyre hand while placing a block

[quaint mantle]

Abstrsact class is.. Kinda both

[summer scroll]

If you want to get the information from the ItemStack, you could detect the hand.

You could try tho.

The BlockPlaceEvent#getItemInHand

[noble lantern]

Yeah cant hurt to try ofc was just curious before trying it or wether i had to do some jank stuff between events to get item in hand xD

[summer scroll]

So I have a simple task from school, make a method to calculate area of triangle by using inheritance concept, it's overcomplicating stuff but idk

[quaint mantle]

Any extra details? You have triangle class that, maybe, extends Shape?

[summer scroll]

That's what I'm thinking right now, but I don't know what to put on the Shape class.

No extra details, literally that's it.

[quaint mantle]

Hm, make it abstrsact and make an abstrsact calculateArea method on it. Then, make Triangle extend Shape and implement the method

Thats clearly polymorphism, but..

[summer scroll]

haha

ik it's only overcomplicating a simple thing but it's still a task

[lost matrix]

  public abstract double calculateArea();

[summer scroll]

abstract is not inheritance right?

[drowsy helm]

What do you mean by that?

[summer scroll]

inheritance as a concept of oop

[drowsy helm]

abstract method just has to be overriden on the class extending it

[summer scroll]

read this first

[drowsy helm]

ah mb

[lost matrix]

Circle extends/implements Shape and thereby inherits the method calculateShape() from Shape

[drowsy helm]

yeah abstraction is inheritance

hey smile havent seen you here for a while

[lost matrix]

😋 .

[summer scroll]

Like this I guess lmao

public abstract class Shape {
    public abstract double calculateArea();
    public abstract double calculateVolume();
}

public class Triangle extends Shape{
    private double base, height;
    public Triangle(double base, double height){
        this.base = base;
        this.height = height;
    }
    @Override
    public double calculateArea() {
        return 0.5 * base * height;
    }
    @Override
    public double calculateVolume() {
        throw new UnsupportedOperationException("This shape doesn't support this method!");
    }
}

[lost matrix]

Make the abstract class an interface

Abstract class only makes sense if you have a state

[summer scroll]

alright

thanks

[quaint mantle]

I mean, he should solve that task with inheritance

[lean gull]

can anyone help?

[chrome beacon]

Send the error

[lean gull]

no error, just the logger saying that it couldn't create it

even though it did make it but without anything inside it

[chrome beacon]

Get the error you're hiding it with try catch

[hybrid spoke]

where do you place your abstract methods in your abstract class personally?

[lost matrix]

Which can be done with an interface 😄

[lost matrix]

At the bottom

[hybrid spoke]

so under everything else?

[quaint mantle]

Yeah, same

[lost matrix]

public static var
private static var
public static method
private static method
public field
private field
constructor
public method
private method
public abstract method
protected abstract method

this is what i do currently

[chrome beacon]

In the try catch tell it to print the error

It's that simple

[lean gull]

idk how to do that

[chrome beacon]

Intellij should already do it for you

(When you tell it to add try catch)

[quaint mantle]

nice minecraft font

how to have it..?

[lean gull]

this? idk i'm just guessing
plugin.getLogger().info(e.getMessage());

[lean gull]

it's in the intellij settings or whatever, idk

go on the settings and search for font

[lost matrix]

You just need to catch the IOException. What you do in your catch block is irrelevant.

[lean gull]

what does that mean

[lost matrix]

You can take that literally.
try { Code } catch(IOException e) { Handle exception }

[lean gull]

??

[lost matrix]

https://www.w3schools.com/java/java_try_catch.asp

[lean gull]

this doesn't say how to send the error

[lost matrix]

Use
Exception#printStackTrace()

If you want to create a file, you have to make sure that all folders in its path are actually present.

isn't that this?

yeah but

which one

adopt, oracle, openjdk, ...

[quasi flint]

adopt

[tender shard]

I heard goot things about graalvm

anyone ever used that?

[drowsy helm]

is there even a noticeable diff between jvms

[ivory sleet]

Isn’t that to run JavaScript on the jvm?

[ivory sleet]

Yes

[tender shard]

https://www.graalvm.org/java/

it's a normal JDK

[ivory sleet]

Some have patches for certain things others are meant for debugging

[tender shard]

they claim to be about 10% faster than other JDKs but tbh 10% isn't that much

I'll probably just use the normal openjdk from Debian's official repos

[drowsy helm]

10% across the board?

damn

very bold

[tender shard]

yeah well one dude claims it to be 8-11% faster, no idea how true that statement is though 😄

[ivory sleet]

Would like to see some statistics on that :0

[tender shard]

I mean, I could also claim that my plugins are 8-11% better than other ones.... 😄

I don't believe them until there's some proof 😄

I'll just go with openjdk 17 for now which is included in debian anyway

[trail flume]

Anyone know how these are done? This is on the OriginRealms (spigot, not modded) server. I know it's a resource pack but how exactly could I replicate this in code and in my resource pack?

[humble heath]

how do i get the player head to show the playes skin

[trail flume]

SkullMeta skullMeta = (SkullMeta) item.getItemMeta();
skullMeta.setOwner("Commandcracker8");
item.setItemMeta(skullMeta);
```Something like that

[lean gull]

i'm not sure exactly how did they did, but i would use the bossbars and custom fonts

[trail flume]

that's a good shout

[lean gull]

also i mean like to remove a bossbar texture, then add multiple bossbars set to unicode characters that are then textured in a font and aligned with the ascent thing

[trail flume]

yeah

is it possible to set a custom bossbar texture?

like with nms or something

[trail flume]

hang on

SkullMeta meta = (SkullMeta) playerHead.getitemMeta();

skullMeta.setOwner(list.get(i).getDisplayName());
skullMeta.setDisplayName(list.get(i).getDisplayName())

playerHead.setItemMeta((ItemMeta) meta);

Custom textures

[trail flume]

but how in code

[stone sinew]

Just a hologram with a character that has its texture changed in a resource pack.

[trail flume]

But they're not holograms... they're on the player's screen

[humble heath]

nope still nothing

[lean gull]

yapperyapps, i think commandcracker8 is asking on how to make bossbars

[stone sinew]

Yeah was moving to that next.

[stone sinew]

Then try boss bar textures

[trail flume]

How do I change the texture though

Of a bossbar

[lean gull]

for that you'll need to ask in a different discord server about fonts and textures

[trail flume]

ok

[stone sinew]

Either the font or the bar.

[trail flume]

How can I remove the bar?

is that possible

[humble heath]

it works now thank you

[lean gull]

wrong discord server bud

[trail flume]

its plugin dev but ok

[stone sinew]

If you modify the bars texture you can

[lean gull]

it's not, it's the texture

[trail flume]

ok

[young knoll]

Generally they use a font to show a custom texture

[trail flume]

im not entirely sure how I'd achieve that

[lean gull]

i still need help if anybody's up for it

[young knoll]

It tells you file is null

[lean gull]

what does it mean though

[young knoll]

It means tabFile is null

[lean gull]

it made the file tho

can anyone spot my error? when i break a block that exists it removes the block but executes player.sendMessage(ChatColor.YELLOW + "[WATCHBLOCK B] Block was not protected.");

dont even understand how thats possible...

[hybrid spoke]

yeah lemme take my holy crystalball and clairvoyance what your methods do

[paper viper]

what does sqllogger

do

[pastel stag]

the methods do exactly what they're named to do blockexists just checks if the block exists in an sql database, removeblock removes it from the database

[paper viper]

maybe something changed in the database

when you try calling it again

[pastel stag]

the only explanation here is that something else is removing it right?

[hybrid spoke]

we would need to see what your methods do to help you

otherwise we can just speculate

How can I send a video in here?

[hybrid spoke]

drag n drop

otherwise a link

Hello!
I am making Spheres with Particles by rightClicking. If I rightClick again the radius gets bigger. By pressing left click I can "shoot" the sphere by moving the center. Everything functions right with the small radius. However, once I shoot the middle or the big one, everything goes right until it should stop. The Runnable doesnt stop then it just starts from the top again although "done" is true. Pls help me I cant find the error.

[hybrid spoke]

remove those embeds

[hybrid spoke]

seems like you never cancel the scheduler

[slim kernel]

it does the execute method and then check if done is true it functions in every other Task I did and functions if the radius is 1

[hybrid spoke]

so you mean because it needs a sec to fade out or what

[slim kernel]

Yeah you can see by the debugs in the chat that done is already true and it should stop but it doesnt then it starts again and spawns a sphere again after the explosion @hybrid spoke

When I do the small one I get done in the chat and it stops as it should

[hybrid spoke]

there is so much boilerplate code

[slim kernel]

I am sorry I still need to learn alot I will try to improve it after I fixed the error

[mortal hare]

i fear no man... but that thing:

java.util.ConcurrentModificationException: null
        at java.util.HashMap$HashIterator.nextNode(HashMap.java:1584) ~[?:?]
        at java.util.HashMap$KeyIterator.next(HashMap.java:1607) ~[?:?]

it scares me

[hybrid spoke]

so you mean it starts from new after being done? or is it really just that 1 second fade like in the video?

[slim kernel]

After the "true" "done" "true" it should be finished. But the there is the "false" again which means it started again somehow and done is "false" again @hybrid spoke

[hybrid spoke]

where do you execute it

[slim kernel]

I call this method on rightclick in the PlayerInteractListener

[hybrid spoke]

i guess you are starting it over and over again

with your rightclicks

[humble heath]

how do i check to make shour that it is a player head that someone is clicking

[hybrid spoke]

so since your middle one needs 2 rightclicks, you start it 2 times. same for your big one just 3 times

[hybrid spoke]

you want to check if the one who just clicked is a material?

[slim kernel]

I set the done to true before so It should be finished and then started again. But it probably is does not have enough time to finish right?

[hybrid spoke]

this seems like a result of static abuse

[slim kernel]

whats static abuse?

[slim kernel]

yeah you were right I just tested it

ok so i removed the part that runs the TabManager class in the main class, and then i put the thing that sets a line in the config file in the loadConfigManager() method and everything is working. now, i'm guesing that this means that the order is wrong, but the thing is, is that in onEnable i run loadConfigManager() first AND THEN i do the TabManager thing... so what do i do?

[humble heath]

might help to register the events in the main class
