the amount of broilerplate and shit visual bukkit creates

when it makes the code

not sure if its going to be faster either

Hello, I am receiving an issue where my listener will not be called for some weird reason. Does anyone perhaps know any suggestions? Here is what my code looks like:

public class Main extends JavaPlugin {

  public static Main instance;
  public static HashSet<Player> players = new HashSet<Players>();

  @Override
  public void onLoad() {
    instance = this;
    Bukkit.getServer().getPluginManager().registerEvents(new MyListener(), this);
  } 

  public static Main getInstance() {
    return instance;
  }

}

public class MyListener implements Listener {
   
  public static void onWalkEvent(PlayerMoveEvent event) {
     Main.players.add(Bukkit.getPlayer(event.getPlayer().getUniqueUuid()));
     event.getPlayer().sendMessage(ChatColor.GOLD + "You have walked!");
     event.getPlayer().sendMessage("test");
  }

}

#

I am new to Java

eternal night Apr 2, 2021, 12:36 AM

#

Your listener methods cannot be static

#

They also should be annotated with @EventHandler

wicked shale Apr 2, 2021, 12:36 AM

#

Oh

#

public class Main extends JavaPlugin {

  public static Main instance;
  public static HashSet<Player> players = new HashSet<Players>();

  @Override
  public void onLoad() {
    instance = this;
    Bukkit.getServer().getPluginManager().registerEvents(new MyListener(), this);
  } 

  public static Main getInstance() {
    return instance;
  }

}

public class MyListener implements Listener {
   
  @EventHandler
  public void onWalkEvent(PlayerMoveEvent event) {
     Main.players.add(Bukkit.getPlayer(event.getPlayer().getUniqueUuid()));
     event.getPlayer().sendMessage(ChatColor.GOLD + "You have walked!");
     event.getPlayer().sendMessage("test");
  }

}

#

like this?

eternal night Apr 2, 2021, 12:37 AM

#

Looks better yes

wicked shale Apr 2, 2021, 12:37 AM

#

alright I will give it a shot

eternal night Apr 2, 2021, 12:38 AM

#

Tho Bukkit.getPlayer(event.getPlayer(). get UniqueId()) seems just. Like. Why XD

wicked shale Apr 2, 2021, 12:38 AM

#

Oh

eternal night Apr 2, 2021, 12:38 AM

#

Like event.getPlayer already returns the player

wicked shale Apr 2, 2021, 12:38 AM

#

I see

#

so unecessary tight coupling

#

right

#

Yeah it seems to work

#

But wait

#

why do people say not to use static?

#

some other people in other discord told me that

eternal night Apr 2, 2021, 12:39 AM

#

I mean for the listener method you just straight up can't

#

Spigot won't allow it

wicked shale Apr 2, 2021, 12:39 AM

#

for set

quaint mantle Apr 2, 2021, 12:40 AM

#

What's a good redis library to use for a plugin?

eternal oxide Apr 2, 2021, 12:40 AM

#

you are overriding an existing method in the Listener so your method footprint must match

eternal night Apr 2, 2021, 12:40 AM

#

eternal oxide you are overriding an existing method in the Listener so your method footprint m...

No he isn't

eternal oxide Apr 2, 2021, 12:40 AM

#

Static is fine when used correctly.

wicked shale Apr 2, 2021, 12:41 AM

#

this kid looks cool https://github.com/PulseBeat02

eternal night Apr 2, 2021, 12:41 AM

#

This is not an overwrite

quaint mantle Apr 2, 2021, 12:41 AM

#

Lord have mercy 👴 🤏 👓

#

the static

wicked shale Apr 2, 2021, 12:41 AM

he seems like a good coder

eternal night Apr 2, 2021, 12:41 AM

#

Kekw

#

Okay then

eternal oxide Apr 2, 2021, 12:41 AM

#

@eternal night all plugin implementations of listener are overiding the Listeners method.

eternal night Apr 2, 2021, 12:41 AM

#

No. Open the listener interface

#

Find me those methods

#

That are overwritten

#

Please

eternal oxide Apr 2, 2021, 12:42 AM

#

Oh I see what you are saying, they are annotated not overridden

eternal night Apr 2, 2021, 12:42 AM

#

Yes

paper viper Apr 2, 2021, 12:42 AM

#

I wanted to pretend to be a beginner

#

and make shitty code

eternal night Apr 2, 2021, 12:42 AM

#

So you wasted my time

paper viper Apr 2, 2021, 12:42 AM

#

and see how ppl would react

#

lmao

eternal night Apr 2, 2021, 12:42 AM

#

Sweet

#

I really enjoyed it

paper viper Apr 2, 2021, 12:43 AM

#

Its okay! I know you are a good programmer now

#

lol

eternal night Apr 2, 2021, 12:43 AM

#

Ah.

#

But yeah. Elgar the listener class is traversed using java reflections to find all methods annotated with Eventhandler

#

So it isn't really overwriting

#

More like, following a schema.

eternal oxide Apr 2, 2021, 12:44 AM

#

Yep

eternal night Apr 2, 2021, 12:44 AM

#

Hence why static doesn't work, because static methods are not considered in that traversal

deft sedge Apr 2, 2021, 12:57 AM

#

is there a way for me to get a function to return two different types of variables

eternal oxide Apr 2, 2021, 12:57 AM

#

yes

deft sedge Apr 2, 2021, 12:57 AM

#

How?

eternal oxide Apr 2, 2021, 12:57 AM

#

create a return type object that holds two

deft sedge Apr 2, 2021, 12:58 AM

#

ok

cinder thistle Apr 2, 2021, 12:58 AM

#

What points should be considered in the MySQL vs Mongo argument? I wanna know why we don’t just all use mongo (although sql is older and therefore has more users and people comfortable with it)

deft sedge Apr 2, 2021, 12:58 AM

#

but what do i set the public thingy to

cinder thistle Apr 2, 2021, 12:58 AM

#

I guess also all data is maintained via the same commands

deft sedge Apr 2, 2021, 12:58 AM

#

I want to return an item meta

eternal oxide Apr 2, 2021, 12:59 AM

#

then set the return as public ItemMeta

deft sedge Apr 2, 2021, 12:59 AM

#

ok

#

waht about the static

#

some people use public static, whyat does that mean?

eternal oxide Apr 2, 2021, 12:59 AM

#

static is really for utility methods

deft sedge Apr 2, 2021, 1:00 AM

#

k

eternal oxide Apr 2, 2021, 1:00 AM

#

I should say, mostly for

#

a static method or field only ever has one instance

deft sedge Apr 2, 2021, 1:00 AM

#

it's mad a tme

eternal oxide Apr 2, 2021, 1:00 AM

#

you need a method name

deft sedge Apr 2, 2021, 1:00 AM

#

ohh

#

nvm i forgot

#

i remebmer now

#

thx

eternal oxide Apr 2, 2021, 1:01 AM

#

public ItemMeta methodName() {}

deft sedge Apr 2, 2021, 1:01 AM

#

k

#

What changes do I have to make to this, i'm trying to check the players inventory for the specifc material that is given

#

I found this code on bukkit forms so it's probably wrong

#

@eternal oxide

#

or anyone else

eternal oxide Apr 2, 2021, 1:12 AM

#

if you just want to see if a material exists inv.contains(Material)

#

to see if a certain amount exists inv.contains(Material, amount)

#

Javadocs are your friend https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/Inventory.html

deft sedge Apr 2, 2021, 1:15 AM

#

well I want to get the meta of that certain material, but I think i figured this one out

#

thanks!

#

i am trying to make a function bc this will probably happen a lot

#

my goal for what i'm doing now is to remove certain item from the invenotry

#

so i think if i can get the meta of that item, i can then remove it

eternal oxide Apr 2, 2021, 1:16 AM

#

ItemStacks have meta not Material

deft sedge Apr 2, 2021, 1:17 AM

#

oh

#

my goal is to be able to do stuff with things I find in their invenotry. Like for example, If I find a book I wanna add a page to said book

#

how would I do that?

eternal oxide Apr 2, 2021, 1:19 AM

#

if you just want to remove if found use the contains method to make sure it exists, then use inv.remove(Material)

deft sedge Apr 2, 2021, 1:19 AM

#

ok

eternal oxide Apr 2, 2021, 1:19 AM

#

all the methods available for Inventories are in those javadocs

deft sedge Apr 2, 2021, 1:19 AM

#

ok thanks

sullen dome Apr 2, 2021, 1:38 AM

    @EventHandler
    public void onLogin(AsyncPlayerPreLoginEvent event) {
        if (config.contains("verify." + event.getUniqueId())) {
            return;
        }
        String code = ThreadLocalRandom.current().nextInt(100000, 999999) + "";
        idCode.put(event.getUniqueId(), code);
        codeID.put(code, event.getUniqueId());
        codes.add(code);

ideas why the last line codes.add(code); doesnt't add anything?

eternal night Apr 2, 2021, 1:39 AM

#

How is the Set/List initialized ?

#

Where are you checking the list later on

sullen dome Apr 2, 2021, 1:39 AM

#

private List<String> codes = new ArrayList<>();

#

in a JDA-Event

#

 if (!codes.contains(code)) {
            channel.sendMessage("Dieser Code existiert nicht. Bitte versuche es erneut oder kontaktiere einen Admin.").queue(); // code doesn't exist.
            System.out.println(codes);
            return;
        }```

it just prints out ```[]```

eternal night Apr 2, 2021, 1:40 AM

#

They use the exact same instance of your listener I suppose ?

sullen dome Apr 2, 2021, 1:40 AM

#

idk

eternal night Apr 2, 2021, 1:40 AM

#

Creating an instance of this class twice would explain the issue

#

How do you not know lol XD

sullen dome Apr 2, 2021, 1:41 AM

#

maybe i am? :o

builder.addEventListeners(new ConsoleLogListener(), new VerificationManager());
        Bukkit.getPluginManager().registerEvents(new VerificationManager(), this);```

#

is that the reason why?

eternal night Apr 2, 2021, 1:41 AM

#

Yeah no you are using two different instances

#

Yes

#

Your listener instance of the class is mutating the list it owns

sullen dome Apr 2, 2021, 1:41 AM

#

ah nvm

eternal night Apr 2, 2021, 1:42 AM

#

While your jda instance is just vibing with an empty list

sullen dome Apr 2, 2021, 1:43 AM

#

 VerificationManager vfManager = new VerificationManager();
        builder.addEventListeners(new ConsoleLogListener(), vfManager);
        Bukkit.getPluginManager().registerEvents(vfManager, this);```

so i guess, this fixes it?

eternal night Apr 2, 2021, 1:43 AM

#

I mean.

#

Give it a whirl

#

Test it out

sullen dome Apr 2, 2021, 1:45 AM

#

wow that actually worked. thanks!

#

leaked my uuid 😕

eternal night Apr 2, 2021, 1:46 AM

#

No problem XD it's a very common mistake when not using static for once

sullen dome Apr 2, 2021, 1:47 AM

#

i am still a bit stuck at static abuse tho... but outside of that, i guess i am pretty good at stuff now after like 14 months

eternal night Apr 2, 2021, 1:47 AM

#

Nice 💪💪

sullen dome Apr 2, 2021, 1:48 AM

#

yoinked discordSRV xd

#

oh god

#

leaking my uuid is different from leaking my ip

young knoll Apr 2, 2021, 1:49 AM

#

You mean 127.0.0.0

sullen dome Apr 2, 2021, 1:49 AM

#

was it that?

#

lol

#

isnt that showing the ipv4 normally?

#

or not at localhosts

limber dust Apr 2, 2021, 1:53 AM

#

127.0.0.1 is just localhost XD

sullen dome Apr 2, 2021, 1:55 AM

#

yeah ik

#

but usually it shows the real ip... and i just saw an ip and paniced lol

but is there a simple way for me to make it so that they can't loose hunger

#

other than peaceful mode

eternal oxide Apr 2, 2021, 2:05 AM

#

schedule a repeating task that sets the players saturation every 20 ticks

deft sedge Apr 2, 2021, 2:05 AM

#

Wil this work?

lunar moat Apr 2, 2021, 2:06 AM

#

probably

deft sedge Apr 2, 2021, 2:06 AM

#

k thix

eternal oxide Apr 2, 2021, 2:06 AM

#

that will only stop them losing health, not hunger

lunar moat Apr 2, 2021, 2:06 AM

#

are you sure?

#

Called when a human entity's food level changes

eternal oxide Apr 2, 2021, 2:06 AM

#

um, you are correct. I'm just tired

deft sedge Apr 2, 2021, 2:17 AM

#

eternal oxide that will only stop them losing health, not hunger

well it does niether

#

so what did I do wrong is the question

young knoll Apr 2, 2021, 2:17 AM

#

Registered?

deft sedge Apr 2, 2021, 2:17 AM

#

I have to register?

like that

k thx

young knoll Apr 2, 2021, 2:22 AM

#

~~Spoonfeed~~

lunar moat Apr 2, 2021, 2:22 AM

btw StopHungerLoss class needs to implement Listener

deft sedge Apr 2, 2021, 2:22 AM

#

k thx again

lunar moat Apr 2, 2021, 2:25 AM

#

ebon birch is it possible to grab a permission in prelogin?

you can listen to the PlayerLoginEvent

#

idk if that helps

ebon birch Apr 2, 2021, 2:25 AM

#

kinda, i guess i could kick after they login

#

i just wanted to kick during the prelogin ~~login~~ process instead of after

lunar moat Apr 2, 2021, 2:26 AM

#

ebon birch i just wanted to kick during the prelogin ~~login~~ process instead of after

that's the PlayerLoginEvent

ebon birch Apr 2, 2021, 2:26 AM

#

i meant during prelogin sorry lol

lunar moat Apr 2, 2021, 2:26 AM

#

when the player joins the server the PlayerJoinEvent is fired

deft sedge Apr 2, 2021, 2:28 AM

#

@lunar moat Thanks It works!

        if (!p.hasPermission("luna.join")) {
            p.kickPlayer("Not Allow lmao");
        }
    }

something like this?

lunar moat Apr 2, 2021, 2:29 AM

#

yeah I think so

young knoll Apr 2, 2021, 2:30 AM

#

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerLoginEvent.html has a player entity, you can probably check permissions here

carmine urchin Apr 2, 2021, 2:36 AM

#

Usually when entering a portal, the portal searches for an area to create the portal. If it cannot find a safe space it creates the portal with four extra obsidian blocks at the bottom. Not sure if anyone has heard of this but it usually happens when you enter in ocean. When setting a portal location to a different world with e.setTo, (PlayerPortalEvent), and when in my case the portal cannot find a safe spot, it sets the location of the portal at y 246. Anyone know how I could make the y level for the portal the same as vanilla? (Nvrmind I fixed this with location.setY(50)

ebon birch Apr 2, 2021, 2:40 AM

don't just ask what you're doing wrong

explain your issue

#

its not kicking me when i join even though i dont have the permission

young knoll Apr 2, 2021, 2:42 AM

#

Are you op

ebon birch Apr 2, 2021, 2:43 AM

#

nope

cinder thistle Apr 2, 2021, 2:45 AM

#

It might be that you’re listening too early in the login process

ebon birch Apr 2, 2021, 2:45 AM

#

should i try at the playerJoinEvent?

cinder thistle Apr 2, 2021, 2:46 AM

#

Because at that time, many things might not have loaded yet. This would likely include kicking because it would reply on you being fully connected

#

Yeah give it a shot

#

But it might run when you switch worlds idk

young knoll Apr 2, 2021, 2:47 AM

#

Don't kick them

#

use event.disallow

am i able to then send a kick/error message?

Then I’ll help you

vale zealot Apr 2, 2021, 2:51 AM

#

sorry if I sound crazy, I literally just started and have no idea how anything works.

#

Im talking about the things like @Override, etc

tight coyote Apr 2, 2021, 2:51 AM

#

so annotations

vale zealot Apr 2, 2021, 2:51 AM

#

yes

young knoll Apr 2, 2021, 2:51 AM

#

Override is a normal java annotation, you should learn the basis first

tight coyote Apr 2, 2021, 2:52 AM

#

Exactly what I was going to say

#

or basically..

vale zealot Apr 2, 2021, 2:52 AM

#

I guess what I'm trying to ask is where do I start

lunar moat Apr 2, 2021, 2:53 AM

#

learn core java first

#

the language features, object orientation

tight coyote Apr 2, 2021, 2:53 AM

#

I love OOP...

young knoll Apr 2, 2021, 2:53 AM

#

There are hundreds of free tutorials for Java online, you should take a look there

vale zealot Apr 2, 2021, 2:54 AM

#

Ok thank you guys!

#

I was trying to tackle the entire plugin thing first but I need to learn Java in order to begin. Thanks for the help, will do!

ebon birch Apr 2, 2021, 2:56 AM

#

it works! thanks!

mystic lion Apr 2, 2021, 2:56 AM

#

Anyone want to try and improve on this code?
https://paste.md-5.net/zequyawudu.java

#

And tell me what I can improve, to improve my java knowledge

lunar moat Apr 2, 2021, 2:57 AM

#

well, you don't need the addEnchantmentLevels method

#

because you can simply use setEnchantmentLevel(getEnchamentLevel() + how many levels you want to add)

mystic lion Apr 2, 2021, 2:58 AM

#

Well... what if I'm wanting to have that method for the sake of the code looking shorter/cleaner

lunar moat Apr 2, 2021, 2:59 AM

#

yeah if you are repeating code it is not looking cleaner

mystic lion Apr 2, 2021, 2:59 AM

#

I meant in other classes

lunar moat Apr 2, 2021, 2:59 AM

#

it is basically the same method

mystic lion Apr 2, 2021, 2:59 AM

#

        setEnchantmentLevels(name, getEnchantmentLevel(name) + level);
        //applyItem();
    }```

#

How about that?

#

Better?

lunar moat Apr 2, 2021, 3:00 AM

#

yes

mystic lion Apr 2, 2021, 3:01 AM

#

anything else?

lunar moat Apr 2, 2021, 3:01 AM

#

the same thing applies to the removeEnchantmentLevels method

mystic lion Apr 2, 2021, 3:02 AM

#

Already done

#

: )

lunar moat Apr 2, 2021, 3:02 AM

#

but other than that your code looks fine imo

mystic lion Apr 2, 2021, 3:02 AM

#

Aight

ebon birch Apr 2, 2021, 3:15 AM

#

i just realized that the plugin needed to be for bungeecord...

#

#

how do i get permission information from bungee lmao

deft sedge Apr 2, 2021, 5:14 AM

#

I am trying to scan player inventory for a spicific item which is targetI Then I want to get the info of that item in the inventory. End goal is to check if there's a book and then get the meta and other stuff avbout the book. The code is mad at me for this

#

Any Ideas?

young knoll Apr 2, 2021, 5:15 AM

#

I is an integer

#

You want an Itemstack

#

I recommend you refresh yourself on java

deft sedge Apr 2, 2021, 5:16 AM

#

I know that it's an integer. god i'm bad at wording questions, I kind of meant what do I need to change to check all of the slots You don't have to answer, I know you've been helping a lot

#

All the stuff I can find on what I want to do is outdated

young knoll Apr 2, 2021, 5:17 AM

#

With your current loop you’ll need to get the item from getContents at that index

#

Or you can switch to an enhanced for loop and compare them directly

#

Also the basics of what you want to do aren’t outdated

deft sedge Apr 2, 2021, 5:18 AM

#

ik but all questions on it are

#

Can I have a link to or an example of an enhaced loop

#

?

#

if u don't want to, just say so ik i've been asking A LOT today

deft sedge Apr 2, 2021, 5:20 AM

#

thanks

#

I do this but it is mad at me. I'm sure i'm doing something wrong @young knoll

young knoll Apr 2, 2021, 5:32 AM

#

You access array elements with []

deft sedge Apr 2, 2021, 5:33 AM

#

so .get contents [i]

#

but i tried that and it didn't work

#

@young knoll

#

i'm definently not picking up on something obvious

quaint mantle Apr 2, 2021, 5:36 AM

#

ItemStack diamond = new ItemStack(Material.DIAMOND);

deft sedge Apr 2, 2021, 5:36 AM

#

yea ik

#

i have material stored as a varialbe

limber dust Apr 2, 2021, 5:41 AM

#

deft sedge I do this but it is mad at me. I'm sure i'm doing something wrong <@!12534952024...

    Arrays.aslist(player.getInventory().getContents()).forEach(item ->{
             //code
        });```
or do the same thing but forloop

#

for(ItemStack item : player.getInventory.getContents()){
}

deft sedge Apr 2, 2021, 5:42 AM

#

ok

young knoll Apr 2, 2021, 5:42 AM

#

Probably best to avoid the stream

#

They aren’t exactly the fastest

limber dust Apr 2, 2021, 5:42 AM

#

i know

#

just he wasn't getting anywhere

deft sedge Apr 2, 2021, 5:42 AM

#

thanks

limber dust Apr 2, 2021, 5:43 AM

#

not in a bad way

deft sedge Apr 2, 2021, 5:43 AM

#

is there an easy faster one then stream?

limber dust Apr 2, 2021, 5:43 AM

#

sorry

#

changed it

deft sedge Apr 2, 2021, 5:43 AM

#

no not like that lol

#

i'm a noob

limber dust Apr 2, 2021, 5:43 AM

#

use asList

deft sedge Apr 2, 2021, 5:43 AM

#

thx for the help

#

ok thx

#

so they both do the same thing

#

but the for loop is simpler right?

limber dust Apr 2, 2021, 5:44 AM

#

either one will do what you want

deft sedge Apr 2, 2021, 5:44 AM

#

ok

#

thanks

young knoll Apr 2, 2021, 5:44 AM

#

limber dust for(ItemStack item : player.getInventory.getContents()){ }

This is probably still the best option, it avoids making a list

limber dust Apr 2, 2021, 5:44 AM

#

ye

deft sedge Apr 2, 2021, 5:44 AM

#

yea i'm gonna do that

limber dust Apr 2, 2021, 5:46 AM

#

that way each time it loops you get a instance directly from the loop

deft sedge Apr 2, 2021, 5:47 AM

#

Do I have to put targetI somewhere else? it's not detecting it (TargetI is the item that I want to look for)

limber dust Apr 2, 2021, 5:48 AM

#

        for(ItemStack item : player.getInventory().getContents()){
            //code here
        }``` you don't need the current part

deft sedge Apr 2, 2021, 5:48 AM

#

k

limber dust Apr 2, 2021, 5:48 AM

#

since you already have the ItemStack

#

eg

#

        for(ItemStack item : player.getInventory().getContents()){
            //code here
            item.setType(Material.DIRT);
        }```

deft sedge Apr 2, 2021, 5:49 AM

#

How do i know if the item i'm looking for is what it found

#

sorry i'm being really slow

#

I only want it to trigger if it finds the item i want it to find

young knoll Apr 2, 2021, 5:49 AM

#

Compare the type

#

Or use isSimilar

deft sedge Apr 2, 2021, 5:50 AM

#

ok so in for loop ill do item.isSimmilar(TargetI)

limber dust Apr 2, 2021, 5:50 AM

#

if you want to stop the loop when it finds the target

#

just do if(isSimilar()){
return;
}

deft sedge Apr 2, 2021, 5:50 AM

#

yea

#

ok

#

thanks

young knoll Apr 2, 2021, 5:55 AM

#

Return will return the entire method

#

Use break if you don’t want that

deft sedge Apr 2, 2021, 5:56 AM

#

ok thanks

limber dust Apr 2, 2021, 5:56 AM

#

thats right XD

#

my bad

deft sedge Apr 2, 2021, 5:57 AM

#

I want to get the variable invitemmeta out of this for loop. I tried delcaring it up above, and that didn't work

limber dust Apr 2, 2021, 5:58 AM

#

you don't need the second ItemMeta

young knoll Apr 2, 2021, 5:58 AM

#

You are trying to declare it again

#

I strongly suggest you get a good grasp on java basics before working with the API

limber dust Apr 2, 2021, 5:59 AM

#

^

deft sedge Apr 2, 2021, 5:59 AM

#

K so like that?

#

and i'll look into that tmr

#

it's late

#

ok nvm

#

i got it

#

thanks ya'll

young knoll Apr 2, 2021, 6:00 AM

#

That if statement isn’t in use

deft sedge Apr 2, 2021, 6:00 AM

#

ik

#

i'm putting it into use rn lol

quaint mantle Apr 2, 2021, 6:04 AM

#

since it implements Iterable u can just do for (ItemStack itemStack : player.getInventory())

quaint mantle Apr 2, 2021, 6:35 AM

#

What is the best way to serialize a BannerMeta (CraftMetaBanner) for storing in Redis? Bonus points if I can actually deserialize it

#

theres a serialize method that'll convert it to a <String, Object> map

#

to unserialize it, look at the constructor in CraftMetaBanner that takes a Map<String, Object> as the argument

#

Couldn't be bothered, I'm using Apache SerializationUtils.serialize and base64

Hey Guys,
maybe some of you can Help me with my Problem. My Problem is, when the InventoryClickEvent is called and I am in my custom Inventory he doesn't cancel the event when the Item is not an specif Item.

else if (event.getWhoClicked().getOpenInventory().getTitle().equalsIgnoreCase("Your Documents") && event.getInventory().getSize() == 18) {
            if (event.getClickedInventory() == null) {
                return;
            }
            if (event.getClick().equals(ClickType.NUMBER_KEY)) {
                if (event.getHotbarButton() != -1) {
                    event.setCancelled(!isDocument(event.getCurrentItem()) && !isDocument(event.getCursor()));
                }
            }else {
                event.setCancelled(!isDocument(event.getCurrentItem()) && !isDocument(event.getCursor()));
            }

private boolean isDocument(ItemStack item) {
        try {
            if (item.getType().equals(Material.AIR) || item.getType().equals(Material.WRITABLE_BOOK) || item.getType().equals(Material.WRITTEN_BOOK) || (item.getType().equals(Material.PAPER) && item.hasItemMeta() && !item.getItemMeta().hasCustomModelData())) {
                return true;
            }
        } catch (NullPointerException ignored) {
        }
        return false;
    }

heavy mason Apr 2, 2021, 8:46 AM

#

event.getClick() == ClickType.NUMBER_KEY - Enums can be compared with ==

#

Try that @abstract spindle

abstract spindle Apr 2, 2021, 8:46 AM

abstract spindle okay I will try

        } catch (NullPointerException ignored) {
        }

This is the stuff that leads to problems which will lead to days of search.
NEVER ignore a NPE like that. Handle your exceptions properly.
When you have a null pointer then look into your code and see where you messed up.
This is the equivalent of putting ear buds in when the fire alarm goes of...

#

and equals vs == doesnt matter when using enums. Internally its just == anyways.

heavy mason Apr 2, 2021, 8:53 AM

It is really important that you create variables here. You need to stop stacking methods. You should not just ignore the character limit.
Your code should be thin enough that you can read it on a small 4:3 screen.

There's got to be a better way to do this, right? I'm thinking DI might be beneficial. If it's the best way to go, then I'll switch from an interface to an abstract class.

I'm using YamlConfiguration.saveAsString() because it looks like the easiest way of serializing a bukkit object to put in redis

You can always serialize bukkit objects as Strings using BukkitObjectOutputStreams if you dont mind using nms.

wet breach Apr 2, 2021, 1:56 PM

#

@sleek pond using Kotlin is perfectly fine

#

still compiles to byte code that is no different then what java does itself

#

Be nice if people stopped actually caring about the language someone is using especially if it isn't even remotely relevant given the problem occurring -.-

Don’t you still need to shade Kotlin for the plugin to work

wet breach Apr 2, 2021, 1:58 PM

No

the Kotlin compiler will turn Kotlin code into appropriate standard JVM Bytecode

meaning you can use a Kotlin JVM for it or Java JVM and it wouldn't matter

At least to get the API ^^'

It doesn't have an API from the looks of it

#

It does seems to have one ^^

wet breach Apr 2, 2021, 2:12 PM

#

probably should bug them to release an API lib then

#

instead of forcing the developers to buy the plugin that they are not using other then for development purposes

opal sluice Apr 2, 2021, 2:14 PM

#

Yeah, I'll write them to ask for it since it's a bit annoying to ask the customer for it's copy of the plugin to actually dev on it ^^'

wet breach Apr 2, 2021, 2:15 PM

#

Yep probably wise. Never makes sense to have a premium plugin that has an API, but restrict the developers from actually obtaining said API lol

#

so as long as that is the case, not many people will develop additional resources for a premium plugin since you know the barring to entry for it legally.

opal sluice Apr 2, 2021, 2:16 PM

#

Yeah, I guess that's why the most of the integration of this plugin is in other "Mythic" line up plugin

minor garnet Apr 2, 2021, 2:18 PM

#

mm

wet breach Apr 2, 2021, 2:18 PM

#

yes talking about the keyword

#

using that keyword makes the method synchronized in that it forces anything using to wait in line

fading lake Apr 2, 2021, 2:19 PM

#

oh thats useful, I've never seen it used before lol

eternal oxide Apr 2, 2021, 2:19 PM

all threads have to syncronize on that object when they access it

wet breach Apr 2, 2021, 2:19 PM

#

Not something you should toss everywhere, but still handy in some cases like dealing with an Array for example 😛

eternal oxide Apr 2, 2021, 2:20 PM

#

synchronize forces them to take turns in accessing

fading lake Apr 2, 2021, 2:20 PM

#

wait does that mean if you call something async then it calls a synchronized method, then it waits for the synchronized method to finish before continuing with the async method?

eternal oxide Apr 2, 2021, 2:20 PM

#

yes

fading lake Apr 2, 2021, 2:20 PM

#

🤔

wet breach Apr 2, 2021, 2:20 PM

#

Alternatively you could also use volatile keyword too @fading lake

fading lake Apr 2, 2021, 2:21 PM

#

wait what does that one do, apologies not seen these used before

#

@quaint mantle blockbench

wet breach Apr 2, 2021, 2:21 PM

#

volatile forces cloned objects to merge with the master @fading lake so that everything has the same state for an object 😉

#

so if an object is allowed to be used Asynchronously, you can put that asynch object into a method where anything else accessing said method async will merge their copy of the object with the master, that is where the object originated from.

#

Thus, even if its async the object state is maintained regardless who has a copy using that method

How do I disable that Spawn get's generated on load of a world?

wet breach Apr 2, 2021, 2:28 PM

#

The volatile modifier is used to let the JVM know that a thread accessing the variable must always merge its own private copy of the variable with the master copy in the memory. Accessing a volatile variable synchronizes all the cached copied of the variables in the main memory.

#

Has its uses, but just like synchronized not something to just toss everywhere as well 😛

fading lake Apr 2, 2021, 2:30 PM

#

ah okay

wet breach Apr 2, 2021, 2:30 PM

#

@fading lake always nice to randomly gain some insight on using something that is rather easy thing. IE using synchronized keyword on an array to stop CME's instead of changing the entire method XD

oh wait I think I understand now, so imagine a class like this

  public boolean a = true;
}

if I had 2 different runnables doing stuff with it, and one of them changed it's value, the other thread wouldn't notice it normally. Would the volatile keyword make both threads cache a live/updated result of when the volatile variable changes?

obtuse basin Apr 2, 2021, 2:34 PM

Well I mean let’s say you create new WeakReference(new Boolean(true)); this would instantly be cleared as you never put a strong reference to that boxed boolean object passed. But if you’d do smtng like:

class a extends JavaPlugin {
  Boolean b = new Boolean(true);
  void onEnable() {

minor garnet ```vb public void tick() { for (Arrow a : arrows) { if (...

3 ways of doing this:

Use an iterator and its remove() method
Create a second empty collection. Then while iterating over the original you add all elements that should be removed to this extra collection.
After iterating you simply remove all elements that are in the new collection.
Use the removeIf() method

ok

One spoon:

  public void tick() {
    final Iterator<Arrow> iterator = this.arrows.iterator();
    while (iterator.hasNext()) {
      final Arrow arrow = iterator.next();
      if (arrow == null || arrow.isDead()) {
        iterator.remove();
      } else {
        if (arrow.hasMetadata("sniper")) {
          particle(EnumParticle.CRIT_MAGIC, arrow.getLocation());
          return;
        } else if (arrow.hasMetadata("comum")) {
          particle(EnumParticle.CRIT, arrow.getLocation());
        }
      }
    }
  }

paper viper Apr 2, 2021, 3:02 PM

you don't cast if you specify the generic arguments the first place

Because the best collection for removing while iterating is LinkedList.
Thats also the only thing a LinkedList is good at. Otherwise its trash.

so, to get an entity I usually use metadata

wet breach Apr 2, 2021, 3:04 PM

@minor garnet Collection is a term to refer to things like arrays or hashmaps. Easier to refer them that way because there is quite a bit of them, and they well collect stuff and sometimes collect other collections etc etc.

heavy mason Suggest adding a check if the item is null so you don't get NPE

Ur probably not here but I did do that if the item isn't null it doesn't return the item maybe i'm missing something, but in my case the player will pretty much always have the item.

Iterable is the base interface
Collection inherits from Iterable
The base collections (List, Set, Queue) inherit from Collection
Then each base collection has specific implementations
List > LinkedList, ArrayList etc
Set > HashSet, TreeSet etc

generally bad practive to return nulls @deft sedge second you are not checking if the item is null rather its metadata. Which will result in an NPE in itself if the item is null to begin.

Avoid returning null whenever possible

will it store null to the variable if i return null

?

wet breach Apr 2, 2021, 3:11 PM

#

makes it easier when you have other code logic relying on the method and if there is problems down the chain, makes it quite clear or more clear where that problem is at and why.

#

@deft sedge depends how exactly you are doing it. The way you have it in your code, that object only persists so as long as the code in that method is running, but all those objects disappear once you return it like you are.
