how can i make .* also match linebreaks?

using java.util.regex.Pattern and Matcher, idk if there is a diffrence with String.replaceAll, but i specify just in case

[lost matrix]

Regex is witchcraft

But i think there is some s modulator for that

let me take a quick look. But when im gagging while looking at regex ill just stop.

[craggy cypress]

How can i get a damaged anvil in 1.12.2, I looked into the docs but block.getData() is deprecated

Normally you can still use deprecated methods, But it doesn't work.

So i was wondering if there are other methods to get a damaged anvil with the PlayerInteractEvent

[lost matrix]

Ok. Try to compile the Pattern with the DOTALL flag to make the dot wildcard also include line breaks.
Example:

Pattern.compile(".*key : value.*", Pattern.DOTALL);

[lost matrix]

If you work with old spigot versions then deprecation warnings are no concern for you.

[fluid cypress]

thats what i was looking for, thanks

[maiden briar]

       Bukkit.getWorlds().add(Bukkit.createWorld(new WorldCreator(world)));```
This gives me an exception if I try to `Bukkit.getWorld(world);` directly after?

[fluid cypress]

idk why the most popular answer to that in stack overflow is "use this [\na-zA-Z]"

[quaint mantle]

oh

im blind

i should read first

[civic lantern]

Guys I need some help that I use a vanish plugin and it doesn`t remove the vanished player from the server list online players
Can you help?

[quaint mantle]

Can you rq gimme an example of how i would add an amount to with an item

i dont understand how it works xD

[maiden briar]

It took me 10 minutes to find out that it has to be == 😦

[quaint mantle]

nothing really working right?

[lost matrix]

Nope

[quaint mantle]

welp that's sad I guess we gotta use what we have then

[cold tartan]

my plugin just isnt working, no error message or anything

ive never faced this issue before so im not sure what to do

[lost matrix]

What are you doing?

[cold tartan]

well i just set it up with a start message so far

[lost matrix]

If you execute /pl is your plugin listed?

[cold tartan]

lemme check

[cold tartan]

nope

[lost matrix]

Then scroll up and see if you got an error early on

[cold tartan]

nope dont

[lost matrix]

Not possible. If there is a jar in the plugins folder that could not be loaded as plugin then you will see a stack trace.

[cold tartan]

yeah thats what im confused about too

do u have a java decomp? i can send u the jar

[lost matrix]

Stop the server. Put in the jar. Start the server.
Doesnt matter what the jar contains. If it couldnt be loaded then you will see a stack trace in your console.

[cold tartan]

i put that into the plugins folder

here is the log:

[lost matrix]

Doesnt matter what it contains.
This is a binary outcome.

1. The plugin gets loaded and is listed under /pl
2. You get a stack trace

[cold tartan]

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

[cold tartan]

im aware, thats why im really confused

[lost matrix]

Always test your plugins in a clean environment btw.

[cold tartan]

wdym?

oh

with no other plugins

ok

i mean the nbtapi im using with gradle loads

[lost matrix]

Your plugin is enabled.

[cold tartan]

but the plugin itself doesnt

should i send my gradle.build or something

[lost matrix]

Again:
It is not possible to shade one plugin into another.
Not with gradle nor with maven.

[echo basalt]

You can shade all classes but not a plugin (without modification)

[cold tartan]

ok

[paper geyser]

do you have a .yml

[cold tartan]

plugin.yml, yeah

[paper geyser]

hmm

[gleaming grove]

Someone knows why i cant cast it to LectureInventory?

[echo basalt]

LecternInventory is the inventory that belongs to the lectern block

[lost matrix]

1. The cast is obsolete

[echo basalt]

Also pretty sure you need nms to do this stuff

[lost matrix]

You can just return the Inventory there. Casting within this method makes no sense.

[gleaming grove]

i make this to show problem with few lines of code, i will need LecternInvetory in other place

[shadow gazelle]

So I have a command that adds an NPC with whatever specified name when you use with it. When I use reload, the click event I have stops working. It does basically nothing, I'm already uninjecting the player packets onDisable, do I need to remove them, too?

The click event is still working, i.e. I can spawn another one and it works, but clicking one of the old NPCs (from before the reload) doesn't do anything

[hollow sand]

How do I check if a player doesnt have a potion effect?

[lost matrix]

You probably have some sort of map that just gets cleared

[hollow sand]

I've searched everywhere but cant find anything

[lost matrix]

  public boolean hasAnyPotionEffects(Player player) {
    return !player.getActivePotionEffects().isEmpty();
  }

[shadow gazelle]

All the NPCs get loaded again from the storage file and put back into the list of NPCs

[hollow sand]

Thanks!

[lost matrix]

So the event is called but not delegated to the NPC?
Check where the delegation fails.

[shadow gazelle]

Where would I even start?

[hollow sand]

But if I wanted to put it in a bukkit runnable, would I have to do it like

@EventHandler
    public void onJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        if(player.hasPermission("staff.join")) {
            return;
        }
        else{
            player.addPotionEffect(new PotionEffect(SLOW, 500, 60));

            new BukkitRunnable() {
                @Override
                public void run() {
public boolean hasSlowEffect() {
  return !player.getActivePotionEffects().isEmpty();
}

                }
            }.runTaskLater(this, delay)
        }```

?

[shadow gazelle]

runTaskLater

[lost matrix]

This will produce a memory leak

Ah never mind

Thought it was runTaskTimer

[hollow sand]

oh aha, but would it work?

[lost matrix]

You are declaring a method inside another method. This isnt even valid java. It wont compile.

[lost matrix]

What IDE are you using?

[hollow sand]

Intellij Ultimate

[lost matrix]

Then go into your class and press Ctrl + Alt + L

[hollow sand]

with the code, right?

[lost matrix]

Doesnt matter. Just click into the class and press the shortcut

[hollow sand]

oki

[hollow sand]

ok i did, it said, 'formatted 4 lines'

[lost matrix]

Good. Next: Dont declare a method inside another method.

[valid crag]

learn java

[proud basin]

Anyone know why im getting this? error: cannot find symbol iPlayer.setCooldown(res.getString("Cooldown")); symbol: method setCooldown(String) location: variable iPlayer of type IPlayer

[quaint mantle]

@lost matrix

[quaint mantle]

what is highlighted

[lost matrix]

Thats just a basic mock up. Creating a proper attribute system can get quite complex.
For now you should just create a simple Map<> that contains the attributes

[lost matrix]

Moar code pls

[proud basin]

I was just showing the error

but really there isn't any code because im using lombok

private final UUID uuid;
    private String cooldown;
    private long time;

    public IPlayer(UUID uuid) {
        this.uuid = uuid;
    }

    public UUID getUuid() {
        return uuid;
    }

Iplayer ^

[lost matrix]

Make a screenshot of the location that contains the error -.-

[proud basin]

symbol: method setCooldown(String)
location: variable iPlayer of type IPlayer

[lost matrix]

Show the entire IPlayer class including the annotations

[dusk flicker]

why do you have another getter when using lomboks getter?

[lost matrix]

Apply @Getter or @Setter to the fields or use @Data on the class.

[proud basin]

never bothered removing it

[manic bison]

hey, how can i do to prevent player from right clicking or left clicking ?

i have a weapon plugin which when you right click a weapon, it fires a projectile.

and i'd like to prevent player from right clicking / left ny item

[lost matrix]

cancel PlayerInteractEvent

[manic bison]

i've tried on if(action == Action.LEFT_CLICK_BLOCK) {
event.setCancelled(true);
} but it doesnt work

or anything

    public void onInteract(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        Action action = event.getAction();
        Player playerr = (Player) player;
        if(playerr.hasPotionEffect(PotionEffectType.BLINDNESS) && playerr.hasPotionEffect(PotionEffectType.SLOW)) {
        if(action == Action.LEFT_CLICK_AIR) {
            event.setCancelled(true);
        }
        if(action == Action.RIGHT_CLICK_AIR) {
            event.setCancelled(true);
        }
        if(action == Action.LEFT_CLICK_BLOCK) {
            event.setCancelled(true);
        }
        if(action == Action.RIGHT_CLICK_BLOCK) {
            event.setCancelled(true);
        }
        if(action == Action.PHYSICAL) {
            event.setCancelled(true);
        }
        }
    }```

[proud basin]

Like java @Setter private String cooldown

[lost matrix]

Yes.

[proud basin]

What would that do?

I already have @Getter and @Setter above the class

[hollow sand]

bukkitrunnables are timed by miliseconds, correct?

[shadow gazelle]

No idea

packet uninjection and injection are fine

[lost matrix]

No. Ticks,

[shadow gazelle]

It loads them right

[hollow sand]

how much is 1 tick in seconds

[lost matrix]

Did you enable annotation processing in your IDE

[shadow gazelle]

There are 20 in a second

[lost matrix]

If the server doesnt lag than it has 20 ticks per second.

[proud basin]

probably how can I check?

[lost matrix]

You can write that in 5 lines:

  @EventHandler
  public void onInteract(PlayerInteractEvent event) {
    Player player = event.getPlayer();
    if (player.hasPotionEffect(PotionEffectType.BLINDNESS) && player.hasPotionEffect(PotionEffectType.SLOW)) {
      event.setCancelled(true);
    }
  }

Just make sure to actually register the listener

[lost matrix]

Do you have intellij?

[hollow sand]

so if im not dumb it would be 1200 seconds

[lost matrix]

Per tick?

[hollow sand]

per 60 seconds

[lost matrix]

yes

[hollow sand]

omg

im so smort

[lost matrix]

quick mafs

[proud basin]

https://imgur.com/vSk44Lt

[hollow sand]

yes yes yes

[manic bison]

i did reg it

[hollow sand]

Thank you sensei 🙏

[manic bison]

thanks

[lost matrix]

Do you use maven?

[proud basin]

no

[lost matrix]

Did you use lombok before and it worked then?

[proud basin]

yea

[lost matrix]

Then restart your IDE

[hollow sand]

I believe in Maven supremacy 🙏

[proud basin]

Tried that

[quaint mantle]

Yes

[manic bison]

it still doesnt work actually

[lost matrix]

Add debug messages.
Directly after the event starts and directly after the condition.

[manic bison]

i added sysouts

it sys'ed out on console but still works ig

[lost matrix]

What still works?

[manic bison]

right clicking an item

in crackshot, there are weapons, and i'd like to cancel the weapon right / left click action, so people cant right / left click weapon, in order the weapon doesnt fire projectiles

[hollow sand]

I was drinking chocolate milk and was watching memes, as I was drinking, I saw this funny ass meme and spat all over my screen

[lost matrix]

What do you mean by that?
Other eventhandler methods still get the event.
If you want to ignore cancelled ones then you need to do the following:

  @EventHandler(ignoreCancelled = true)
  public void onInteract(final PlayerInteractEvent event) {
    // Some custom stuff
  }

Or:

  @EventHandler
  public void onInteract(final PlayerInteractEvent event) {
    if(event.isCancelled()) {
      return;
    }
    // Some custom stuff
  }

[hollow sand]

nice

code

[manic bison]

basically, in my server, when a player right clicks a wooden shovel, it fires projectiles (wooden shovel = crackshot weapon)
but i want to prevent the player from right / left clicking the wooden shovel, so the wooden shovel doesnt fire projectiles

[valid crag]

you basically cancel the interact event and set the item use result to deny

and then pray that crackshot actually respects cancelled events

[lost matrix]

Then you need to check if the event was cancelled in the listener that is used to fire the projectiles.

[valid crag]

if it doesn't, you have to get smart about it

[manic bison]

so i take the fire projectile event, then i cancel it

[valid crag]

and that usually involves reflective bullshittery

[lost matrix]

Do the projectiles get fired from another plugin?

[manic bison]

yep

[valid crag]

crackshot, as mentioned

[grim ice]

anyone has an idea of a spigot plugin

that doesnt suck

[quaint mantle]

No

[valid crag]

no, they all suck

[manic bison]

handcuffs

[valid crag]

without exception

[quaint mantle]

hey nnyak

[valid crag]

hello

[dusk flicker]

lmao

[lost matrix]

Then you are out of luck. Write the dev that he should make his event handling more robust.

[grim ice]

OO

[valid crag]

ask them to respect cancellations

[dusk flicker]

bye

[proud basin]

So you don't know how to fix it 7smile7?

[valid crag]

or get around it with a reflective hack

I had to do that with slimefun once

[manic bison]

alrighty, thanks 4 help

[quaint mantle]

you can stay aslong as you dont be a dick

[lost matrix]

A plugin to import arbitrary shapes and animations from blender to make giant walking multiblock monsters.

[valid crag]

getting soft I see

[quaint mantle]

nope

[valid crag]

can I use my old account to not be a dick

[quaint mantle]

nope

[valid crag]

how about a new account that looks exactly the same

[quaint mantle]

nice pfp

[shadow gazelle]

@lost matrix yeah, it just doesn't detect right clicks on NPCs after reload

[valid crag]

search result 25 for "batman avatar"

[ancient whale]

Hey I'm looking how to properly handle async tasks (especially for dbs) can anyone give a quick look to this one and tell me if this is a good one to learn from ? https://www.spigotmc.org/wiki/asynchronously-working-with-a-database/

[shadow gazelle]

?paste

[undone axle]

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

[lost matrix]

What do you mean "detect"
Where do you listen for the right clicks? Event level or packet level?

[lost matrix]

How did you know its him?

[valid crag]

it's pretty obvious

[quaint mantle]

"reflective bullshittery"

who the hell else says that

[lost matrix]

I see XD

[valid crag]

need to keep the obvious alts obvious so that the sleeper alts go under the radar, after all

[quaint mantle]

[shadow gazelle]

I have an event called RightClickNPC which returns the player and npc, the click event that uses it just opens the inventory. This is the read packet function:
https://paste.md-5.net/ixisuwonug.cpp

[lost matrix]

Do you receive a packet?

[shadow gazelle]

Yes

Wait

Let me test something

[lost matrix]

You are iterating over all NPCs every time you get an interact packet on an entity. This just sounds like a lag machine with extra steps.

[valid crag]

Doesn't the entity interact packet have the uuid of the clicked entity directly, or something

[proud basin]

bump

[shadow gazelle]

Yep, receiving the packets

[hollow sand]

do guis start from 0-9 or 1-9

im confused

[lost matrix]

The int id. Yes. So he could just use a Map<Integer, EntityNPC>

[lost matrix]

Not enough infos.

[valid crag]

i vaguely think that there might be a way to get an entity by eid through Bukkit, but that might be paper only

[lost matrix]

Inventory slots start at 0

[valid crag]

basically everything starts at 0

java is zero indexed

[grim ice]

anyone has an idea of how can i stun players

[opal juniper]

apart from lua

[grim ice]

i might use pot effects but its a weird way

[eternal oxide]

its saying there is no setCooldown method in IPlayer

[proud basin]

But there is...

@Getter
@Setter
public class IPlayer {

    private final UUID uuid;
    private String cooldown;
    private long time;

    public IPlayer(UUID uuid) {
        this.uuid = uuid;
    }

    public UUID getUuid() {
        return uuid;
    }

}

[eternal oxide]

Not one that takes a String

[proud basin]

Yea

[lost matrix]

What does your auto completion tell you?

[hollow sand]

so it would be 0-9

ye?

[valid crag]

0-8

[dusk flicker]

do me a favor and remove the getUuuid and the getter and setter and put a @ Data and see if that changes it

[shadow gazelle]

How would I do that otherwise?

[eternal oxide]

type IPlayer.

[hollow sand]

o h

ok, ty

[proud basin]

setCooldown(String cooldown)

[lost matrix]

Map<Integer, NPC>

[hollow sand]

now i just got to do intense meth

maht

math

[eternal oxide]

Compile time error using Maven.

[proud basin]

same thing

[valid crag]

lombok 💯

[lost matrix]

Your annotation processing might be broken. Have you tried the @Data annotation. Also pls remove the duplicate UUID getter.

[eternal oxide]

I can;t remember the name of the tool you are using for teh getter/setter

[dusk flicker]

lombok

[eternal oxide]

thats it

[proud basin]

Yeah tried that

[eternal oxide]

Have you checked HOW to use Lombok with Maven?

[dusk flicker]

What he's doing should work

I use lombok and like

[proud basin]

I know how to use it

[dusk flicker]

Just something's odd

[valid crag]

the tool that saves you time on not having to write things that your IDE would already write for you

[granite stirrup]

Lombok is useless to me

[valid crag]

and then wastes your time with things like these

[lost matrix]

Download and install lombok again. Then add the newest lombok jar to your dependencies.

[eternal oxide]

Have you added lombok as a dependency in yrou pom?

[proud basin]

using gradle

[eternal oxide]

or configured it as a plugin in pom?

[granite stirrup]

your*

[dusk flicker]

you have the lombok plugin in your ide right?

[valid crag]

try using ant

[eternal oxide]

gradle or not, you still have to configure it as a plugin in your build enviroment

[granite stirrup]

#FuckGradle

[lost matrix]

And then you can also roll back to java 6 while you are at it

[proud basin]

lmao

[proud basin]

yes

compileOnly 'org.projectlombok:lombok:1.18.20'
    annotationProcessor 'org.projectlombok:lombok:1.18.20'

that's what I have in my depend

[eternal oxide]

yep

[dusk flicker]

they use it diff on the lombok site

[grim ice]

anyone has an idea

of how do i check

if a player is right clicking right npw

now

[dusk flicker]

Are you using the lombok gradle plugin jtx?

[lost matrix]

PlayerInteractEvent

[proud basin]

no without the plugin

[grim ice]

lmao

this only checks

[dusk flicker]

okay then use

[grim ice]

for a 1 click

:/

[dusk flicker]

repositories {
    mavenCentral()
}

dependencies {
    compileOnly 'org.projectlombok:lombok:1.18.20'
    annotationProcessor 'org.projectlombok:lombok:1.18.20'
    
    testCompileOnly 'org.projectlombok:lombok:1.18.20'
    testAnnotationProcessor 'org.projectlombok:lombok:1.18.20'
}

[proud basin]

that's what I have...

[grim ice]

i want to check if the player is holding

right click

[dusk flicker]

You said you have half of that

use ALL of it

[proud basin]

you don't need the other ones

[granite stirrup]

No it's supposed to do all clicks

[dusk flicker]

Try it

[proud basin]

oh look didn't work

[granite stirrup]

You didn't specify which click

[dusk flicker]

This is straight off of their website; Im only telling you what they legit tell you to do

[lost matrix]

Then you need to constantly check if a player has sent the right click packet and define a tick amount that defines when not receiving a packet means he has stopped.

[dusk flicker]

https://projectlombok.org/setup/gradle

[granite stirrup]

This is why #FuckGradle

[proud basin]

.

[proud basin]

💃

ay look at that I guess restarting your pc fixes it

@lost matrix What did you mean by Use the db data in memory

[lost matrix]

Throw it onto a data structure

[proud basin]

should I be closing the connection after they log in?

or only do it when they disconnect

[lost matrix]

Thats what a connection pool is for.
Always get a new connection, do your transaction, then close the connection again.

[proud basin]

ok

[shadow eagle]

what is the spigot api version for 1.17.1

[lost matrix]

1.17

[shadow eagle]

im making a plugin and in pom.xml i put 1.17.1-R0.1-SNAPSHOT

is that not it

my error says unsupported api version

[lost matrix]

I thought you meant the api version from the plugin.yml

[shadow eagle]

WAIT i may have that wrong xD

[lost matrix]

For the pom its
1.17.1-R0.1-SNAPSHOT

[shadow eagle]

i do smh

tysm!

[shadow gazelle]

How would I get anything from the NPC that was clicked?

Does the packet include the ID of the NPC that was clicked?

Or UUID

[lost matrix]

NPC clickedNpc = npcMap.get(id);
if(clickedNpc != null) {
  // Do stuff with clicked NPC
}

The packet contains the entity id as int

[shadow gazelle]

oh

[lost matrix]

And you even use it... why are you surprised?

[tacit drift]

Has any1 worked with inventivetalent's menubuilder?

or can any1 recommend an api to build menus easier?

[quaint mantle]

Yes useEntity has a method to see if you interacted with an entity

[sleek girder]

Is there a way where if a player sends you a friend request invite, it shows the message with an achievement? Is this possible in java?

[grim ice]

how to send a player a packet to show him that he has an item in his hand but it doesnt actually exist

[lost matrix]

https://wiki.vg/Protocol#Window_Items

[granite stirrup]

No I'm pretty sure its SetSlot

Im pretty sure that is for on join what you said

[lost matrix]

Ah right. This looks better.

[final monolith]

hey guys, can anyone review my code? im trying to make then better https://github.com/LaivyTLife/DataAPI/releases

[lost matrix]

Right away:
Never ever have a public static non final collection.
Dont even have a final one. No public data structures and no passing the data structures to other classes.

[grim ice]

How do i check if an item is not in its place? what event?

[final monolith]

oh, needs put final?

[lost matrix]

Second:
Dont have a hard reference to game bound objects.
No Player, Entities Chunks etc

[granite stirrup]

What's wrong with having public variables

[lost matrix]

should be private final

[lost matrix]

Exposing data structures is very bad practice. Always encapsulate them

[grim ice]

How to check if a item is not in a specific item slot

and then cancel the event that caused that

[final monolith]

needs to access from another classes

[lost matrix]

No. Write mutators.

[final monolith]

getters and setters?

[lost matrix]

No

[valid crag]

the only good public collection is a final and immutable collection

[final monolith]

something like this?

[lost matrix]

This is bad:

This is also bad:

This is the proper way:

[final monolith]

ooh okok

i will use that

thanks for the example

[granite stirrup]

wait how can you remove something from final?

[valid crag]

that isn't what final means

[final monolith]

🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔

[ivory sleet]

I mean encapsulation is good:

• It let’s you rewrite internal state without affecting any dependents. You can easily provide defense copy of your internal list as an example.
• Fields cannot be abstracted, methods can.
• You can have mutable internals while providing no way of mutating internals to the dependent.

[valid crag]

final means you cannot reassign the value of that field

you can't do someMap = someNewMap if it's final

[granite stirrup]

oh

[valid crag]

but you can still use the methods of someMap to change it, to mutate it

[lost matrix]

As long as its immutable its fine. final just refers to the field, not the content

[valid crag]

this is why public maps should be immutable

because final doesn't protect them from being changed

[final monolith]

ok guys, but... Whats the difference? how the immutable HashMap can impact my code?

i dont understand

[lost matrix]

You dont need immutable maps.

just make your map private final and work your way around that.

[ivory sleet]

An immutable data structure disallows any mutation on its structure once created.

[final monolith]

ooh okok

[lost matrix]

final doesnt mean that you cant access the map

[valid crag]

a field is final; an object is immutable

[granite stirrup]

but whats the point if it doesnt make much difference?

[final monolith]

🤔

[ivory sleet]

What are you referring to idkidk?

[granite stirrup]

?

[valid crag]

what doesn't make much difference?

[lost matrix]

Next thing: Use primitives here.
You really dont want to check for null values on a Boolean field.

[ivory sleet]

.

[valid crag]

what's the point of what?

[granite stirrup]

what 7smile was talking about

[lost matrix]

It makes a huge point in your design process and greatly increases the robustness of your code.

[valid crag]

he talked about a lot of things

[final monolith]

private static Boolean saved = false?

[proud basin]

What if I saved the uuid, cooldown, time in a json style? 7smile7

[granite stirrup]

can i make public static final variables in like utilities classes tho?

[lost matrix]

As long as they are immutable

[valid crag]

public anything should always be immutable

[granite stirrup]

what about stuff where it just has methods that messes with the command map?

[lost matrix]

so
No: public static final List<String> SOME_NAMES = new ArrayList<>();
Yes: public static final String SOME_CONSTANT = "Hi";
Yes: public static final List<String> SOME_NAMES = Arrays.asList("One", "Two", "Three");

[valid crag]

arrays.asList is still mutable iirc, it just doesn't allow add

[outer sorrel]

thanks! works now

[lost matrix]

Ah good point

[lost matrix]

Stateless methods can be put static into a utility class

[lost matrix]

As json into your DB?

[proud basin]

Yeah like json {"UUID":"631b2936-7672-474d-9b4f-3366124065f0","Cooldown":"weeklyKit","Time":1627356977681}

[granite stirrup]

ah thing is i have the public static final var for a class instance that i want to be able to access every where

[lost matrix]

No idea why you would do that when you have data thats 100% relational in nature.

[ivory sleet]

I mean you might wanna go with List#of since Arrays#asList is just a fixed sized array list, still mutable by inserting new data into a bounded index.

[lost matrix]

Thats ok(ish) but usually you would want a static getter for this singleton instance. It allows for lazy initialization which is often needed when using with spigot.

[valid crag]

lazy initialization can be really horrible at times, though

at least when implemented poorly

[granite stirrup]

lazy initalization?

[ivory sleet]

Yeah

When the instance might not always be needed, it’s created lazily which is only when the method is invoked for the first time.

[proud basin]

hm ok

[granite stirrup]

public static final SomeClass something = new SomeClass();
i just have this in one class lmao

[grim ice]

uhhhhhhh HELP

[ivory sleet]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply.

[valid crag]

often lazy initialization results in the initialization only ever being attempted once

[grim ice]

how do i give a recipe to a exact person

[valid crag]

and if someone happens to trigger the initialization at the wrong time, the whole runtime gets fucked

[grim ice]

without giving others

[proud basin]

add permissions probably?

[grim ice]

that isnt what i want

[valid crag]

for example, static blocks in classes can be considered to be lazy initializers

as they are only ran when the class itself is loaded and initialized

[grim ice]

Bukkit.addRecipe()

[next crater]

well im not a proffesional dev, but try checking the player that is trying to craft an item?

[lost matrix]

This might be problematic if the the static instance is created when spigot doesnt accept listener registration at the moment.

[grim ice]

adds it for everyone

[lost matrix]

This is lazy and will work more often

[valid crag]

the issue however is that they only ever run once, when the class is first attempted to be initialized

if they fail at that time, they will remain failed until the class is reloaded with a different classloader

[grim ice]

yeah i think i have to check the crafting table grids

[paper viper]

What lmfao

Provider class or something?

[lost matrix]

Never ever manually listen for a NPE.
NPEs are good. They tell you that you fked up.

[granite stirrup]

its just in a class called Utils lmao

[paper viper]

But why

[granite stirrup]

because i want to access it anywhere?

[ivory sleet]

Singleton (:

[paper viper]

But… Utils are supposed to like the methods itself

Should be static in general

For utility classes lol

[ivory sleet]

Yeah utils shouldn’t be confused with singletons

[granite stirrup]

i mean i could do that but where would i put the instance lmao

[paper viper]

Singleton good for providers

Like GSON provider

[valid crag]

Utils are classes that group stateless functions together

[paper viper]

Stuff like that

[lost matrix]

I think utility classes should be stateless and have only static methods

[valid crag]

A singleton is a class that can only have one instance

They have some similarities but are very different

[granite stirrup]

what about ```java
public class Utils {
private static SomeClass someInstance;

public static SomeClass getSomeInstance() {
    if (someInstance == null)
        someInstance = new SomeClass();
    return someInstance;
}

}```

[ivory sleet]

Well not a utility

[valid crag]

That's a singleton

Singleton implies state

Utils should be stateless

[granite stirrup]

?

[ornate hollow]

how can i check if the PlayerLoginEvent is allowed, what result should i look for (asking bc there is Result.ALLOWED and Result.ALLOW)

I need to make sure the event was successful before i save something to a hasmap

[granite stirrup]

yeah i never made a actual utils class before so i kinda need a example on what you mean

[lost matrix]

The heck is "Truncated class file" supposed to mean? Never seen this error before

[honest iron]

I'm just getting it

[valid crag]

make every method static, make every field static, make every field final

[lost matrix]

Is this the full stack trace?

[ornate hollow]

https://github.com/SamiCraft/MainPlugin/blob/main/src/main/java/com/samifying/plugin/DatabaseAccess.java

I had that before, but i forgot what it is, all i know this code works

[tacit drift]

im confused

[valid crag]

and probably also immutable

[granite stirrup]

probs ALLOWED

[lost matrix]

1. Dont use a decade old spigot version
2. Whats in line 17 ?

[tacit drift]

getCommand

is line 17

[lost matrix]

Then you didnt write your command into the plugin.yml

[tacit drift]

oooh

yeah forgot about that

:))))

[honest iron]

i've reached the 2k limit

[granite stirrup]

but can someone tell me how to actually write a utils class

[valid crag]

craftbukkit lmao

[lost matrix]

Just a bunch of static methods and no fields

[valid crag]

well, you can have fields, but they should be static, final, and their contents should be immutable

[granite stirrup]

then where am i supposed to store the instance of a class?

[valid crag]

look at the java Math class for an example

[ornate hollow]

Example

public class PluginUtils {

    @NotNull
    public static String trimUniqueId(@NotNull Player player) {
        return player.getUniqueId().toString().replace("-", "");
    }

    @NotNull
    public static HttpURLConnection fetchBackend(String uuid) throws IOException {
        URL url = new URL(PluginConstants.BACKEND_API + uuid);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        return connection;
    }

    @NotNull
    public static HttpURLConnection fetchBackend(Player player) throws IOException {
        return fetchBackend(trimUniqueId(player));
    }

    public static String getJson(InputStream stream) throws IOException {
        BufferedReader in = new BufferedReader(new InputStreamReader(stream));
        String json = in.readLine();
        System.out.println(json); // Debug
        return json;
    }


    public static BackendData getBackendData(InputStream stream) throws IOException {
        String json = getJson(stream);
        ObjectMapper mapper = new ObjectMapper();
        return mapper.readValue(json, BackendData.class);
    }


    public static BackendError getBackendError(InputStream stream) throws IOException {
        String json = getJson(stream);
        ObjectMapper mapper = new ObjectMapper();
        return mapper.readValue(json, BackendError.class);
    }
}

[valid crag]

you don't store anything

storing things means state

and Utils should be state-less

which means not storing anything anywhere

[lost matrix]

You dont. Everything in the class is static anyways. So you just make an empty private constructor and never create an instance of it

[valid crag]

again, look at the java Math class for an example

[granite stirrup]

but how am i gonna call those methods of that class?

[valid crag]

statically

Class.staticMethod()

[ornate hollow]

UtilsClass.methodName()

[valid crag]

for example... Math.round()

[granite stirrup]

not the utils the one that handles my thing

[lost matrix]

They are static <- So you can call them at any time from everywhere

[valid crag]

again, look at the Math class

[ornate hollow]

go learn oop please

i dont like beeing toxic

but still

[granite stirrup]

no im saying

i have another class...

[valid crag]

that doesn't matter, the Utils methods are static so you can call them, like already stated, from anywhere, at any time

[lost matrix]

Do you compile with jdk 8 ?

[honest iron]

It doesn't run on my computer but it runs on my VPS

[valid crag]

it can be in another class, it can be in another package, it can be in another parallel fucking universe, but static is static and is available as long as the class itself is available

[honest iron]

sec

[honest iron]

yea

[lost matrix]

This might be a really rare edge case of a bug in java 8

[lost matrix]

Try installing a newer java version and see if that fixes it

[granite stirrup]

but this other class i have has a constructor i want to access every method in there every where lmao i need to have a instance of it some where tho

[valid crag]

what does that have to do with your utils class

[granite stirrup]

i want to make a thing that interacts with it and probs more soon

[valid crag]

then just interact with it?

[grim ice]

why do i make my plugins so complicated and not test them man

[granite stirrup]

but where do i put the instance

[valid crag]

you don't put an instance

it's static

[grim ice]

im sure if i test my plugin now itll have like 100000 errors

[ornate hollow]

I recommend you to use hibernate for the database stuff, it will handle all the stuff with connections for you, and you can just focus on developing

[valid crag]

you don't need an instance

[granite stirrup]

i do because i do important stuff in the constructor on my other class

[valid crag]

import != instance

[lost matrix]

Custom mappings are really tedious with JPA entities + hibernate

[ornate hollow]

idk dude so far whatever i did i did with making a backend in spring first, and then from a plugin calling that data, proved to be much faster in the long run

[granite stirrup]

theres no static methods in the other class

[lost matrix]

If you have premapped data types like Date or String then this might be true.
But custom mapping for stuff like Locations is quite the hustle.

[valid crag]

that doesn't matter

Utils is still accessible from that other class

because everything in Utils is static

[proud basin]

Did I do this correct REPLACE INTO kitCooldown (UUID, Time, Cooldown) WHERE UUID = ? VALUES (?, ?, ?)

[granite stirrup]

but how to i access everything in that other class in utils

[valid crag]

you don't

or, if you absolutely need to, you can add the other class as a parameter in your utils method

[ivory sleet]

idkidk the thing with utilities are that they’re utilities. It should help you merely. For instance doing this
calculatePower(double health, double maxHealth) {
return health * 2 + 1 % maxHealth;
}
getPower(Player p) {
return utility(p.getHealth(),p.getMaxHealth());
}

Instead of this

getPower(Player p) {
return p.getHealth() * 2 + 1 % p.getMaxHealth();
}

[valid crag]

and pass this to it

but that can lead to weird and shit design

[granite stirrup]

??

[ivory sleet]

Bad example but yeah, Math class is a great one

[valid crag]

it sounds like an utils class is not what you are looking for

what are you trying to do

[granite stirrup]

trying to access methods and things from another class

[valid crag]

no, that is not what you are trying to do

[granite stirrup]

but i cant make them static since i do things in the constructor in the other class

[valid crag]

describe to me what you are trying to do

"accessing methods and things" isn't an answer

[granite stirrup]

??

[valid crag]

everything in java is "accessing methods and things"

accessing methods and things is how you are trying to achieve it, not what you are trying to do

[granite stirrup]

i just want to grab a instance of a class from some where

[valid crag]

again, that is not what you are trying to do

that is how you are trying to do it

do we have a bot command for xy questions

[ivory sleet]

?xy

[undone axle]

http://xyproblem.info/

[granite stirrup]

that is what im trying to do ??

get a instance of a class from some where everything can access

[valid crag]

alright, fine, let's turn it the other way around

[ivory sleet]

Singleton

[valid crag]

why do you want to do that?

why do you need that instance of a class from some where everything can access

[lost matrix]

To get the instance in the util methods XD

[clear galleon]

new Class() ????

[shadow gazelle]

IntelliJ is saying that id that is returned is from my NPC class

[granite stirrup]

because i have a class that needs a instance of it

[shadow gazelle]

Is my brain just not working and that's the point?

[granite stirrup]

and idk if need it for any others

[valid crag]

and what does this class need it for?

[granite stirrup]

to call some methods of it

[valid crag]

why are you calling those methods?

[granite stirrup]

to do things?

[valid crag]

what things?

[granite stirrup]

like commandmap stuff

[lost matrix]

Have a centralised mapping of entity id and NPC
Map<Integer, NPC>
This way you can directly access your NPC in O(1) if some packet comes in.

[valid crag]

right, so you're working on your commandmap shit

what exactly are you trying to do

[shadow gazelle]

Oh 🤦‍♂️

[next crater]

does anyone has a tutorial about spigot MySQL Databases? I just want to try new things :)

[proud basin]

@lost matrix I would also want to save the kit has been used correct?

[granite stirrup]

¯_(ツ)_/¯

[clear galleon]

so you are trying to get an already existing instance of one class in another class?

[valid crag]

if you want proper help, you need to ask proper questions

[lost matrix]

I dont know how your data is structured and i dont know your schema.
If you want true relation data then create a table for each kit

[valid crag]

what you are asking right now is super fucking vague and there is no good answer

we need to know the use case and what you are doing

[granite stirrup]

idfk what i am doing

[valid crag]

we can see that

[granite stirrup]

im just messing with the commandmap

[valid crag]

then pass the commandmap instance to the thing that is supposed to mess with it

problem solved

[granite stirrup]

im just gonna create this class in the class i need it in lol

[proud basin]

So as long as I am saving the data async I should be fine

[lost matrix]

And also load it async

[proud basin]

right

[lost matrix]

Sure

[odd sentinel]

any ideas why PlayerFishEvent is giving me bizarre item stacks when I catch salmon? https://paste.gg/p/anonymous/f637a075ab0c4127aa9421109b58fce2

[next crater]

I cant open that link btw

now I can

sorry

[odd sentinel]

idk it works for me, but I think that site has had downtime issues recently

[next crater]

no, I just reloaded the link and I can now

@odd sentinel why do you check if the thing you caught is an item

you cant caught like a creeper

everything you fish is a item, right?

[odd sentinel]

idk, but I assume so. that could be null though

so I need a not null check at least

[unreal quartz]

you can hook players and other entities

[next crater]

you´re right

I was thinking about fishing (water)

sorry

[odd sentinel]

I just went with my instanceof to be safe

but that's likely unrelated to getting weird results for salmon

so far, never happens with cod

[unreal quartz]

are other plugins interfering?

don’t see any reason for that to happen

[odd sentinel]

the only other plugin on this dev server is mcmmo because my plugin needs it, so it could be

but I am never given those items either

it's not like extra loot, I just got salmon and cod

[unreal quartz]

mcmmo does modify your fishing outcome based on your fishing skill

[odd sentinel]

right but I'd actually get that loot

[unreal quartz]

unless you’re going to modify the event you could listen on MONITOR

[odd sentinel]

not saying it's not mcmmo, just I am confused

[valid crag]

those look like fishing treasure

[unreal quartz]

mcmmo is probably firing after you

[odd sentinel]

actually that was originally on monitor, I changed it for testing

[unreal quartz]

try it without mcmmo then, if not then i don’t see the issue

[quaint mantle]

where can I find good tutorials for plugins?

[ivory sleet]

Visual or textual

[quaint mantle]

visual

[ivory sleet]

I know the source code and kody simpsons do decent ones

Altho those videos are not really the goto if you wanna write clean code

[next crater]

GHG, CodeRed, TheSourceCode, Kody Simpson

[quaint mantle]

wdym?

[next crater]

my favourite channels

[ivory sleet]

Many Bukkit/Paper/Spigot tutorials are good if you wanna learn how to implement certain features in your plugin, not really demonstrating good architecture and clean code.

[valid crag]

or good anything, for that matter

many spigot/bukkit/paper tutorials fail even at the thing they're trying to present

[ivory sleet]

Of course the code does fine merely if you just wanna get something to work.

[valid crag]

one sql tutorial I don't remember the name of comes to mind

[ivory sleet]

Yeah

🥲

[quaint mantle]

alright do you know any tutorials that would teach me how to organize plugins, or maybe templates even

^textual or visual

[next crater]

what do you mean with "organize plugins"

[ivory sleet]

Probably a clean and decoupled code architecture

[next crater]

hmmmmmm

[valid crag]

just throw a lot of interfaces at it

[ivory sleet]

Well Icy I can redirect you at some stuff, learn about Java’s 23 design patterns, learn about SOLID, lean about all the features Java has.

But that’s probably irrelevant for most spigot devs.

Like ridiculously irrelevant.

[next crater]

@quaint mantle are you a begginer at spigot coding?

[quaint mantle]

yeah

[next crater]

and are you begginer with java?

[quaint mantle]

yeah I have been 'studying' java for a couple months, just looking for stuff to do with it if that makes sense

[next crater]

ok, its nice to know java first before starting with spigot

[ivory sleet]

What level would you say, you’re right now?

[valid crag]

you'll probably stumble for a while over bukkit and its own shenanigans before you can start thinking about how to organize and structure things

[ivory sleet]

Hard self assessment but that might give us a hint on what you should try learn next

[next crater]

man my first plugins code was all in 1 single class 🙄

[quaint mantle]

id probably say beginner to intermediate, but idk

[ivory sleet]

🥲

[quaint mantle]

Ive done some event handler stuff

which is pretty basic

[ivory sleet]

Do you know the difference between an instance and a class

[next crater]

if you have any questions about something in java (like polymorphism, object, etc...) I would suggest you to search at the w3school site, that´s where I started learning 🙄

[granite stirrup]

i found this in String :)))

[quaint mantle]

a class makes objects and isn't instance similar to class or am I wrong

[valid crag]

instance is another word for object

[quaint mantle]

ahh alright thanks for clearing that up for me

[valid crag]

"instance of Player" is a way of saying "object that was created from class Player"

[grim ice]

why is this not working

ItemStack TOKEN = new ItemStack(Material.EMERALD);
                    TOKEN.getItemMeta().setDisplayName(ChatColor.LIGHT_PURPLE.toString() + ChatColor.BOLD + "Staff Token");
                    TOKEN.setItemMeta(TOKEN.getItemMeta());```

[ivory sleet]

Similar but not identical, an instance is a unit from a class. Classes are blueprints to create units/instances.

But anyways that’s a crucially important thing to know if you wanna start upgrading your code architecture

[grim ice]

it just gives a empty emerald when i do the command

[quaint mantle]

alright thank you

[grim ice]

((Player) sender).getInventory().addItem(TOKEN);

[granite stirrup]

isnt the item meta null when its a new itemstack?

or no?

[grim ice]

OH RIGHT

[next crater]

LOL

[valid crag]

itemmeta is null only for air

the issue is that getItemMeta clones the itemmeta

you are calling setDisplayName on a clone; it does not affect the original itemstack

[quaint mantle]

so what are some good first plugin ideas for beginners?

[valid crag]

you need to store the itemmeta in a field and then use setItemMeta on the itemstack

[ivory sleet]

Believe paper has a convenient method ItemStack#modifyMeta(Consumer) which doesn’t clone it or smtng

[valid crag]

that is new

let me take a look

[ivory sleet]

Yeah think it was added very recent

[granite stirrup]

ItemStack is so confusing lmao

[valid crag]

itemstack is horrible in many ways

[ivory sleet]

Indeed

[valid crag]

mmm yes ItemStack::editMeta(Consumer<? super ItemMeta>)

[ivory sleet]

Ah nice

[valid crag]

now if they could make the equals call not clone it 4 times

[granite stirrup]

LOL what

[next crater]

• /fly command that gives the player fly permission, but if the player already has the fly permission, than he would lose the fly permission
• Teleport bow
• a command that launches you idk, maybe 10 blocks at where you are looking at

[ivory sleet]

Didn’t they fix that lol

[next crater]

I never understood, what does the # symbol means?

[quaint mantle]

alright thanks

[ivory sleet]

It’s just an anchor

[valid crag]

I don't know, I've been pretty out of touch with development recently

mostly because I'm still on 1.16

[ivory sleet]

It’s mainly for Javadocs

[granite stirrup]

isnt that javadoc thing

[ivory sleet]

Yeah good point batman

[next crater]

ooooh ok

thx

[ivory sleet]

So you get that hyperlink in javadocs when you generate those btw which takes you to the method belonging to that class (;

[granite stirrup]

editmeta is in 1.16 on paper to

its not in 1.15 tho

[valid crag]

yeah looks like it is

[quaint mantle]

soo its completely fine to put all of my code in the plugin.java file to start out with?

[valid crag]

far from fine but I'd worry about it once I were familiar with bukkit

[quaint mantle]

alright

[granite stirrup]

doesnt Plugin.java already exists?

[shadow gazelle]

Would this work for that map @lost matrix?

    public static Map<Integer, EntityPlayer> npcMap() {
        for (EntityPlayer npc : getNPCs()) {
            Integer npcID = npc.getId();
            npcMap().put(npcID, npc);
        }
        return npcMap();
    }

[ivory sleet]

Looks like StackOverflow error

[shadow gazelle]

I've never done anything with maps before

[valid crag]

you are recursing indefinitely

npcMap calls npcMap calls npcMap

[granite stirrup]

as soon as you run that your server will instantly crash

[valid crag]

well, it'll throw a stack overflow eventually

the jvm can only handle calls going so deep

[granite stirrup]

doesnt that crash the server?

[valid crag]

depends on where it happens

when caused by a plugin, usually not

[granite stirrup]

oh i thought it will lol

[ivory sleet]

I believe somewhere deep spigot uses a try catch (Throwable) or smtng to prevent random shutdowns

[quaint mantle]

public boolean containsInventory(Inventory inventory) {
    if (cache.contains(inventory)) return true;
    boolean v = values().stream().anyMatch(i -> i.getInventory().equals(inventory));
    if (v) cache.add(inventory);
    return v;
}

there's gotta be a better way of doing this

[valid crag]

what is it supposed to do to begin with

[quaint mantle]

when an inventory is clicked it calls like 4 methods, i dont want players to cause performance issues

and i check through a map each method

[valid crag]

no but like what is happening here

[quaint mantle]

Map<String, ShopGUI>

ShopGUI -> getInventory.equals(inventory)

@Data
public class ShopGUI {
    private String permission = "";
    private Inventory inventory;
}

[valid crag]

consider an Inventory -> ShopGUI map?

i'm not sure what you're doing but that'd be what I'd do if this is what I think it is

[quaint mantle]

yeah ill just make this manager class contain 2 maps

[ivory sleet]

What maps?

You might be able to utilize a BiMap depending on circumstances

[valid crag]

that'd take you from ShopGUI to String

[quaint mantle]

its String, Inventory -> ShopGUI

[ivory sleet]

Oh right

[quaint mantle]

whats bimap?

[ivory sleet]

Then nvm

[valid crag]

a map that goes two ways

[ivory sleet]

Yeah key to key basically

[valid crag]

instead of key -> value it can go from value -> key as well

without like having to iterate over the entire thing

[quaint mantle]

i could use that

public String getKey(@NotNull Inventory inventory) {
    for (String key : keySet()) {
        Inventory i = get(key).getInventory();

        if (i != null && i.equals(inventory)) return key;
    }
    return null;
}

it could be used here i imagine

[gritty lake]

Hi is there any solution to fix 1.8 servers can't connect to mysql 8 with is the new default? :/
I updated my plugins to new driver but not able to update other plugins
Many plugins use "com.mysql.jdbc.jdbc2.optional.MysqlDataSource" i believe but on 1.8 it not work anymore but works fine on 1.12+ servers with get me to think 1.8 may using a very outdated driver but i can't update that :/

I also tryed to change characterEncoding on the mysql server but did not work

[valid crag]

sort of, but the inventory -> gui map would serve the same function

[quaint mantle]

alright

[valid crag]

you'd get the gui by the inventory and then call getKey or whatever on the returned gui

[shadow gazelle]

Okay, I'm really stuck now

[quaint mantle]

Hi, could someone help me by giving me ideas of how to make tops, weekly and monthly please?
I can think of ideas but they could kill the database

[valid crag]

leaderboards of what, exactly

what kind of data are we talking about

how often do the criteria update

[quaint mantle]

leaderboards

[valid crag]

yes, but leaderboards for what data

[quaint mantle]

for example kills, deaths, etc

[valid crag]

maintaining a leaderboard is very simple if the relevant values can only increase

things get more difficult for things like killstreaks, that can decrease or reset

[quaint mantle]

Yes, but I would like them to be eliminated from time to time

[valid crag]

if deletions/decreasing criteria are the case, you'll have to maintain the whole thing in order

otherwise you end up going through the entire database whenever someone's score lowers or someone is removed from the board

[quaint mantle]

yes, I understand how they work, where I am stuck is to make the statistics reset every day, week and month

[valid crag]

if you for some reason can't just drop the whole table, you can store an expiry timestamp and reset the values on access if it's expired

[quaint mantle]

ok, I'll be testing it

thx

[shadow gazelle]

Can someone explain how I would make HashMap for my NPCs like 7smile7 said?

new HashMap<>()

[shadow gazelle]

Oh, yeah, wasn't very specififc

[valid crag]

you probably want to store the map somewhere in addition to making it, yes?

[shadow gazelle]

Yes

[valid crag]

and how do we store things in java?

[shadow gazelle]

Do you mean variables?

[valid crag]

variables aren't stored

they poof and disappear when the method they belong to is done

what I'm talking about is fields

a field belongs to an object or a class and exists as long as that object or class exists

[shadow gazelle]

Oh, right

[valid crag]

a regular field belongs to an object, a static field belongs to a class

[shadow gazelle]

My brain is gone because I've spent like an hour trying to figure this out

[valid crag]

do you remember how to declare a field

[shadow gazelle]

Yes

[valid crag]

declare a field of type Map<Integer, NPC> named npcMap

make it private and final

[shadow gazelle]

Okay, got that

[valid crag]

show me what you ended up with

[shadow gazelle]

public final Map<Integer, NPC> npcMap = new HashMap<>();

[valid crag]

right

you now have a map, where you can store things

you can then at a later time read those things

[shadow gazelle]

I know

[valid crag]

what don't you know, then

[shadow gazelle]

Where I store things from, I guess

[valid crag]

a map is also called a 'dictionary'

it allows you to look up things

for example, take a phone book

you look up a person's name, and you end up with their phone number

in your code, you want a dictionary that, given an entity id, gives you an NPC

you then want to take the entity id from the packet, take it to the dictionary, and it'll take you to the NPC

[shadow gazelle]

So pretty much move everything from my List where the NPCs were stored to the Map?

[quaint mantle]

its called a dictionary in cs

[valid crag]

i don't know what your list is, but probably yes

lists are for when you want things to be in order

maps aka dictionaries are for when you need to find things

[quaint mantle]

can be NPC[]

[valid crag]

you don't need your npc's to be in order; you need to be able to find them

[vague oracle]

The map is a key and value based storage you can get the value from the key if you wanted to get a item from a list, you have to loop through and filter them

[quaint mantle]

Integer, NPC is pretty much the same thing as NPC[]

[valid crag]

yes, but NPC[] is not sparse

[shadow gazelle]

So do I just use a for to put the NPCs in that map from the list with the NPCs?

[valid crag]

seeing as eids range in the millions, an array is haram

you can do that yes, but ideally you would get rid of the list altogether

and instead of putting the things in the list to begin with, you'd put them in the map instead

[shadow gazelle]

That would require the map being public and changing like ten other things

[quaint mantle]

ah did not know he was using entity ids as key

[valid crag]

he's listening to packerinos so he has to

it having to be public and changing like ten other things are issues caused simply by poor design

[quaint mantle]

not necessarily a plugin but how would I customize mobs i.e creepers always being charged or zombies having full diamond all the time

[valid crag]

listen to the creature spawn event and perform whatever modifications you see fit on the spawning entity

[shadow gazelle]

Not big changes, now that I look, but how would having to change it to public be poor design?

[valid crag]

because data structures shouldn't be public

you should have accessor and mutator methods like registerNpc(NPC) or getNpc(int entityId)

[shadow gazelle]

How would I call every NPC in a map?

[valid crag]

map.values() returns very value in the map

the better question is why do you need to do that?

[shadow gazelle]

For sending the packet that adds the NPCs

[valid crag]

wouldn't you only want to send the npcs in the player's view-distance

[shadow gazelle]

How am I supposed to put the NPCs into the map and call them with an ID if they use UUIDs?

[valid crag]

they use both UUIDs and IDs

UUID is persistent, ID is not

UUID is an UUID, ID is an int

[torn shuttle]

wth, I bricked intellij again

[valid crag]

intellij is trash

[torn shuttle]

no it's not

[valid crag]

it is though

[torn shuttle]

compelling argument, looking forward to seeing the IDE you created and which is better than intillij

[valid crag]

that doesn't mean it's not trash

[shadow gazelle]

But how is it trash?

[torn shuttle]

I think he's a bot

[valid crag]

commentating on something doesn't require one to be 100% proficient at and capable of fully reproducing the subject of the commentary

it's trash because it's slow as balls, has too many bells and whistles, the UI is annoying and there is too much eyecandy

[torn shuttle]

saying something is trash 5 times in a row and not going into detail is not commentary, it's something I can teach a parrot to do

[valid crag]

it is better than most other IDE's around because it has more features than any other IDE

but it has its own significant share of drawbacks and super irritating issues as well

[torn shuttle]

so the thing that makes it better than the other ides is what makes it trash

gotcha

[minor garnet]

How work the minecraft projectile velocity, when losing velocity between distance ?

[valid crag]

not quite

I would say the thing that makes it trash is a symptom of it being better than the others, combined with a poor mindset or goal at the source

both its advantages and its issues stem from the same root cause

that does not, however, mean that the issues cannot be trimmed out if someone competent actually gave a shit

which is why I label it trash

it is an enermous waste of potential, which to me, is even more haram than not being good to begin with

[prisma needle]

?paste

[undone axle]

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

[torn shuttle]

I see your opinion and I raise my opinion about your opinion: your opinion is an enermous waste of character space

[valid crag]

you're the one who asked for real commentary

[torn shuttle]

no I didn't

[valid crag]

you did

by complaining about me not actually giving commentary

[ivory sleet]

Aye guys we can just stop this IDE debate

[torn shuttle]

I never asked for your opnion, I was just commenting that intellij bricked itself

is anyone having issues with the latest release?

I think it might be a plugin issue

[valid crag]

i'm still using a version from 2019

[ivory sleet]

Latest broke some plugins ye

[valid crag]

this is why I never update anything

[prisma needle]

I'm trying to make some code which will create a new config file (with any name) and the contents from an already made file within the project into the new file. It successfully creates the file, but it is always empty. Is there something I'm doing wrong? https://paste.md-5.net/pehiroreva.cpp

[valid crag]

use JavaPlugin::saveResource

and then load the created file with YamlConfiguration::load

[ivory sleet]

Geek what ya trying to do

That would load the config from the jar

Not the one copied to ur plugin folder

[valid crag]

it'd grab the file from the jar to the destination if it doesn't already exist

[torn shuttle]

are you still using that awful red filter nnya

[valid crag]

and then load the file in the plugin directory

basically saveDefaultConfig

but for any name, not just config.yml

if the resource name and the target file name don't match, you'll have to do stuff with io streams to write it to a different location, but that is only one or two more lines

and yes I'm using the red theme still

[torn shuttle]

is your favorite game doom or something

[ivory sleet]

Ripcord getting any updates with the new threads coming?

[valid crag]

i don't know, I haven't even updated to the version with replies yet

it'll probably take a few weeks or months for threads

[ivory sleet]

Oo yeah, how many developers does it have

[valid crag]

one

[ivory sleet]

Ah fair

[valid crag]

a money hungry fuck who ignores the discord side of the program in favor of slack, because the slack part you have to pay for

so nothing ever gets done

[torn shuttle]

I mean

in fairness

it's probably easier to keep someone banned on a paid service huh

[valid crag]

it's the easiest on a service you run the servers of yourself

like IRC

[ivory sleet]

What is ripcord written in?

[valid crag]

like C or something, I don't remember

[shadow gazelle]

So then how do I insert an NPC into that map?

[torn shuttle]

irc is trivial to bypass bans on

[valid crag]

you get its entity id

[shadow gazelle]

If it needs an integer and NPC

[valid crag]

Entity::getEntityID

yes but on IRC you at least have rangebans

[ivory sleet]

Sounds like a pain in the ass to maintain if it were to use something like that

[valid crag]

on discord you are entirely fucked if someone has a dynamic IP

[torn shuttle]

yeah seems a good reason not to use discord if you don't want to deal with that

[valid crag]

granted you are still kind of fucked if someone uses a vpn, but I'm sure you can rig up something with dnsbls for IRC

discord on the other hand doesn't even let you see an user's IP, let alone block them or prevent them from joining based on it

[shadow gazelle]

Like npc.getId()?

[prisma needle]

yes I know, that's what I'm trying to do (I think)

[shadow gazelle]

npc being an EntityPlayer

[torn shuttle]

based on the skype exploit era I much prefer discord acting as a filter for ips

[valid crag]

an Entity declares a method getEntityID of return type int

yeah, it does have its advantages

[torn shuttle]

remember when you could get anyone's ip on skype by just looking them up

that was fun huh?

[prisma needle]

What do you mean exatly? Can't figure out how that code would look :P

[quaint mantle]

how would I make it so when someone mines an ore it replaces it with stone like it does on hypixel skyblock

[valid crag]

are you replying to something I said? I can't see replies

[prisma needle]

yeah you said "use JavaPlugin::saveResource"

[valid crag]

JavaPlugin::saveResource takes a string and a boolean iirc

the string is the relative path of the resource in your jar

for config.yml, it'd be "config.yml"

the boolean determines whether an existing file at the destination should be overridden

which for your case you probably want to set to not happen

[shadow gazelle]

pog

Now that it's not going to be a lag machine...

[valid crag]

@torn shuttle have they fixed the fucking window focus issue in modern intellij yet

[shadow gazelle]

Back to the original issue
#help-development message

wtf is happening?

[valid crag]

ripcord doesn't support message links

[shadow gazelle]

:l

[shadow gazelle]

e

[valid crag]

nor does it support replies

[shadow gazelle]

https://tenor.com/view/star-wars-visible-confusion-confused-gif-14771834

[valid crag]

basically copypaste the original question or something

[shadow gazelle]

Yeah

So I have a command that adds an NPC with whatever specified name when you use with it. When I use reload, the click event I have stops working. It does basically nothing, I'm already uninjecting the player packets onDisable, do I need to remove them, too?
The click event is still working, i.e. I can spawn another one and it works, but clicking one of the old NPCs (from before the reload) doesn't do anything

[opal juniper]

Just update

Orrrrr use the webpage of discord

Slightly less Intensive than the electron window

[valid crag]

do you receive the relevant packet in your whatever listener

it's still pretty cancerously laggy

[shadow gazelle]

All the NPCs get loaded again from the storage file and put back into the list of NPCs

[shadow gazelle]

Yeah

Wait, if I relog they work

[valid crag]

then simply track down the specific condition that isn't being met

[shadow gazelle]

OH

Got it

onDisable and onEnable needed to add/remove the packets

[warm galleon]

when im using spigot clip why is there no org.bukkit and nothning for my to have my main class extend
how do i use it

[torn shuttle]

which windows focus issue

[shadow gazelle]

When you forget to return true in an onCommand boolean so code runs anyway

[valid crag]

you know those small popup windows that open when you're loading a project?

[shadow gazelle]

No

[torn shuttle]

no?

[warm galleon]

no?

in intellij it does say "open in this window or new window"

[steep nova]

no?

[warm galleon]

but only if theres alr one open

[valid crag]

the small window that says "Loading Project..."

[torn shuttle]

lol the stars aligned there

[normal flower]

clipboard.getRegion() returns the region of the place where I first created the schematic file doing //schem save. How do I get the region of the pasted area? Or even better how do I modify the schematic file before pasting using the world edit API? I can't seem to figure it out.

[valid crag]

with status messages like "reopening files..."

and a loading bar

https://cdn.discordapp.com/attachments/324667367860862977/870449274582880366/image.png

ring a bell?

[shadow gazelle]

wtf is that red

[steep nova]

nope

[valid crag]

do these popup windows not exist anymore in modern intellij?

[shadow gazelle]

But yes, it's there, it's almost unnoticeable with the load speed if your project is small, though

[torn shuttle]

it does exist although by default it doesn't look like it's out of a doom game gui

[warm galleon]

oh yeah i know it

[valid crag]

Well, see, here is one of the things that grinds my gears about it

my machine is slow

[warm galleon]

but since my laptop is a god it appears for .00000000001 seconds

[valid crag]

like, very, very slow

[shadow gazelle]

lol

[valid crag]

which means that this popup is usually open for around 45 seconds

[torn shuttle]

guys no joke this man's computer is legendary
