[limber owl]

Wouldnt that be too small?

[terse raven]

wdym

[brave sparrow]

What do you mean it’s name has version in it

That’s the maven config not the plugin config

[waxen plinth]

They're talking about the build artifact

[limber owl]

Lets take 16 teams of 1 player, then you have 16 chunks, and one chunk is 16 block wide, so they would be dropping too close, won't they?

[brave sparrow]

That’s configurable separately, you don’t need to make version null lol

[terse raven]

then make the play area bigger

[brave sparrow]

Just set a custom radius on your spread

[harsh totem]

Like when I build the plugin it's name is what's in artifactId and then what's inside version in the .pom file.
I want it to just be the artifactId

[limber owl]

So double or triple that

[terse raven]

yea

just divide your play area by the number of teams

[limber owl]

Okay, thanks

What is the new PacketPlayOutMapChunk in 1.18[.2]?

[paper crater]

Anyone know how i can change the specific item back to durability 0 when putting it in a chest/dispenser like the OnWeaponDrop in screen

[chrome beacon]

Use the InventoryClick and InventoryDrag event

[brave sparrow]

ItemStack isn’t mutable down to the NMS, once you modify it you then have to set it

Using the appropriate inventory events

[waxen plinth]

That is an awful practice you're showing there

Can I make some suggestions

[paper crater]

It's for 1.7.10 and modded server so yh lots of stuff not possible

[silent timber]

whoever just replied to me and deleted it, client bound

[paper crater]

and needs to work with modded items hands the reason why IDs is used

[terse raven]

yea sry that was me, just noticed that my question was stupid

[viscid fractal]

Hi quick question, what spigot version do I use to make a 1.8.9 plugin? I assume 1.8.8?

[waxen plinth]

1.18.2

[terse raven]

^

[waxen plinth]

Use latest :)

[viscid fractal]

Oh I can just use latest. Sweet! Thanks

[terse raven]

nonono

but why would you want to use 1.8?

[waxen plinth]

Viaversion for backwards compatibility if you really need people to be able to join from 1.8

[paper crater]

What kind of suggestions?

[brave sparrow]

1.8.8

Not latest

[waxen plinth]

Use hasPermission instead of looping through all permissions

[viscid fractal]

Now confused....

[brave sparrow]

If you don’t want to help the kid just say that guys

[waxen plinth]

Don't copypaste code, extract it into a method

[brave sparrow]

Don’t lie to him

[waxen plinth]

You shouldn't be using such an outdated version and it will be much harder to get support for it

Use latest

[terse raven]

where did you find that?

[viscid fractal]

But it works for a 1.8.9 server?

[brave sparrow]

They don’t support people working on 1.8, if you actually want to do 1.8 spigot use 1.8.8

For a 1.8.9 server, latest will not work, you want spigot 1.8.8

[viscid fractal]

Okay, thank you very much!

[brave sparrow]

Presumably ClientboundLevelChunkWithLightPacket

[paper crater]

Yeahh that code is from my server dev, but he is inactive lately so i'm trying to fix it myself but ye not rlly experienced 😛

[jagged quail]

i bet i dont even need the else if in this: ```java
Player player = (Player) commandSender;
if (flyingPlayers.contains(player.getUniqueId())){
flyingPlayers.remove(player.getUniqueId());
player.setAllowFlight(false);
Msg.send(player, "&cFlight has been disabled.");
} else if (!flyingPlayers.contains(player.getUniqueId())) {
flyingPlayers.add(player.getUniqueId());
player.setAllowFlight(true);
Msg.send(player, "&aFlight has been enabled.");
}

[waxen plinth]

You're PAYING to get code like that?

[paper crater]

No just friends helping out

[waxen plinth]

You don't

Matter of fact this code can be dramatically simplified

[crisp steeple]

bro what the actual hell

a print statement is determining whether or not my code works

??

[jagged quail]

oof

[brave sparrow]

If flyingPlayers is a set

You can replace that contains and remove with just remove

[waxen plinth]

Yep

[brave sparrow]

In a set remove returns true if the element was in the set, false otherwise

[waxen plinth]

It could look like this

[crisp steeple]

anyone have a clue how this is happening

[jagged quail]

could be using getLogger().info(); instead of System.out.println();?

[waxen plinth]

player.setAllowFlight(flyingPlayers.add(player.getUniqueId()));
player.sendMessage(player.getAllowFlight() ? "You can now fly!" : "You can no longer fly!");
if (!player.getAllowFlight()) {
    flyingPlayers.remove(player.getUniqueId());
}```

[crisp steeple]

i mean thats not really the point here

[waxen plinth]

Not sure why you even need to have a Set to keep track of a property that's already stored on the player though

[jagged quail]

i can still make the message send in colour?

[waxen plinth]

Yes

Just edit the strings

[fair sable]

Hello, I am trying to find packet equivalent of a method. This is the method I need: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Entity.html#setRotation(float,float) Because it can rotate passengers without need to eject. Anyone know what packet does it use?
I am using protocol lib so here are the packets types: https://github.com/dmulloy2/ProtocolLib/blob/master/src/main/java/com/comphenix/protocol/PacketType.java

[jagged quail]

intellij asked if i wanted it to be and if else

[brave sparrow]

https://github.com/dmulloy2/ProtocolLib/blob/240920d642be3ff5d84f45586e01ddb2444cf1c2/src/main/java/com/comphenix/protocol/PacketType.java#L148

[jagged quail]

ok i now have this @waxen plinth

[brave sparrow]

Can you send more of your code

[waxen plinth]

Prefer ternaries over inline if-else

[fair sable]

thanks 😄 I will try it

[tender shard]

I guess that's personal preference

[waxen plinth]

Ehhh

It's in the official Google style guide

[tender shard]

I mean I also do love the ? operator

[waxen plinth]

Inline if statements are considered an antipattern

[tender shard]

but there's also nothing wrong in using if else

[waxen plinth]

Use braces

Omitting braces is the antipattern

[tender shard]

+1 for using {

yeah

[waxen plinth]

Not if-else itself

Though to be honest I avoid if-else too

[brave sparrow]

Not using braces is how you get security flaws

[waxen plinth]

Having more than a few in one function is a sign of bad code

[tender shard]

but anyway, if/else is nothing that one should avoid imho

[brave sparrow]

Having a bunch of nested if-else can be a sign of bad code, but not just if-else in and of itself

[waxen plinth]

No, either way

[mortal hare]

Man i have this architectural problem

I have a feature, function which I would like to implement

[waxen plinth]

Nested or not, if you have more than a few in one function something is probably wrong

There are a few exceptions

[mortal hare]

but if i Implement it, there's an impact of performance

[waxen plinth]

It's a rule of thumb

Not a universal truth

[mortal hare]

due to how that feature would remove bunch of optimisations

which I implemented

[fair sable]

it does work when unmounted, but does not work when armor stand is passenger unlike the spigot method

[brave sparrow]

Well the spigot method is likely performing more than one operation

[jagged quail]

should i move my main class from Mecha.class to Main.class?

[brave sparrow]

You’re probably going to need a few different packets

[brave sparrow]

Your main class should not be named Main.class

It should be YourPluginNameHere.class or something to that effect

[waxen plinth]

Explain it

[jagged quail]

hm ok

[fair sable]

how can I learn what spigot method does? someone said on the code side of things its the ClientboundMoveEntityPacket$Rot but it doesnt mean anything to me as idk much about packets

[waxen plinth]

Maybe make a thread

[brave sparrow]

That one will be https://github.com/dmulloy2/ProtocolLib/blob/240920d642be3ff5d84f45586e01ddb2444cf1c2/src/main/java/com/comphenix/protocol/PacketType.java#L147

[fair sable]

thx going to try now

[mortal hare]

I have an experimental UI framework which allows you to simulate clientside inventory actions, the thing is I could reuse some of the handling code from the action handling system I'm currently using, but they're optimised in way, that some actions are remain to be calculated by the client, by that I'm saving bunch of iterations which server doesn't really need to do. On the other side, these optimisations break my feature of clientside interaction simulation which seems like a cool idea, and I can't think of how to implement this gracefully without any performance drops.

[waxen plinth]

Proper abstractions

Have an interface that represents all the needed behavior

For simulating inventory actions, you have an implementation of it that does all the calculations

For non simulated ones it can basically just be a dummy that does nothing

[jagged quail]

makes more sense to put command usage like that?

[mortal hare]

thing is that the implementation is very abstract and action handlers can be swapped due to how strategy design pattern works

its not monolithic

[waxen plinth]

Adding another polymorphic component seems like the solution

[waxen plinth]

Makes more sense to use a framework, default commands suck

[fair sable]

same problem :/

[brave sparrow]

You’ll probably want to look at the decompiled spigot source for that method and see what it’s doing differently from you then

Or look at it on stash

[fair sable]

how can I do that?

[mortal hare]

I would say yes, that way your plugin could properly respond to the changes in the plugin.yml file, if server owner wishes to change the permission nodes or to localize the description of the command (although its not recommended to do it that way, some plugins crash due to this)

although command frameworks are more fancy and flexible to work with

bukkit api should add static tab completion maps to the plugin.yml

that way plugin developers wouldnt need to rely on tab completion events every time, thus save some performance (although not much)

dynamic tab completion are not that common for simple commands

basic dynamic tab completion is already implemented (player names, worlds, etc.)

[silent timber]

Do you know how to get a LightEngine in ClientboundLevelChunkWithLightPacket(Chunk var0, LightEngine var1, BitSet var2, BitSet var3, boolean var4)?

I'm a bit lost trying to interpret the table at https://wiki.vg/Protocol#Chunk_Data_And_Update_Light

[chrome beacon]

So why are you trying to send a chunk packet

[silent timber]

Trying to send chunks from a certain area of the world to the player at a different location

[chrome beacon]

Oh well guess you're going to have to dig around a bit

[quaint mantle]

Hey guys! Need some help.
Does any of you know if there's any way I can set an ItemStack display name in multiple languages? So it's translated client-side?

[ivory sleet]

yeah

[quaint mantle]

Just as any other regular Minecraft item

[vale cradle]

Translatable key in the Resource pack

Or modify the packet before it's sent to the player replacing a specific placeholder with the text in question

[quaint mantle]

Alright, so I must either use a resource pack or deal with packets?

Thank you folks

[vale cradle]

o/

[ivory sleet]

anyway theJsUsed I believe ItemMeta setLocalizedName/getLocalizedName might be for you

or if you use paper then those w/o the get/set prefixes

[spare marsh]

for some reason my plugin runs the onDisable method whenever I do /stop but if I do /restart it doesn't. Anybody know how this is possible>

[quaint mantle]

It's weird, set/get LocalizedName was my first approach, but setLocalizedName only received one single string

shouldn't I be able to set a localized name for English, Spanish, Protuguese and any number of different languages?

[ivory sleet]

ye its the key

yep

but the some.name.key gets translated client sidedly

[quaint mantle]

Okay, I'm not getting it. Sorry if i'm just being dump:
Let's say I got an Itemstack with a glowStone material. I want it to be called "magic dust", but I want English clients to see "magic dust" and Spanish clients to see "polvo mágico". How would I achieve that using the ItemStack's localized name?

[ivory sleet]

Oh custom localized names can only be supported using a resource pack as tommy said, or if you translate it server sidedly

but that presupposed you also are aware of the language of said usr

[quaint mantle]

Ohh! got it!

I guess I'll just translated I server-side. Player#getLocale should be enough to get the Player's language

[ivory sleet]

indeed

[jagged quail]

hey guys

i wanted to make it show the plugin version here

[quaint mantle]

The drawback it that if an English located player crafts my custom item, drops it and then a Spanish located player picks it up, they'll see an English display name and lore.

[jagged quail]

not the server version

does anyone know how to do that?

    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        Msg.send(commandSender, "&7------------= &aMecha &7=------------");
        Msg.send(commandSender, "&aVersion: " + Bukkit.getVersion() + " &ais installed.");
        Msg.send(commandSender, "&4PRE-RELEASE!!! THIS VERSION IS NOT STABLE");
        return true;
    }```

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[humble tulip]

Use dependency injection

[quaint mantle]

Set a static member of type JavaPlugin in your Plugins main class, define it in onEnable(), then access it from your command class

[jagged quail]

okay

[limber owl]

hey, am I dumb because it's too late and I'm overworked or why can't I add player to this Set

private final Set<Player> players = new HashSet<>();

    public void addPlayer(Player player) {
        if(players.size() >= size) return;

        players.add(player);
        Logger.info(getPlayers()); //TODO: remove
    }

in this function

I see it doesn't work

it prints out empty set

that logger is custom class, just shorter bukkit.getLogger()...

    public Set<Player> getPlayers() {
        return players;
    }

getPlayers() function

[jagged quail]

if i can find it

[lethal python]

i've got a PlayerInteractEvent and i'm trying to make it so when a player right clicks a container with a certain item, the container won't open. i've already made a list of every block which does something when you right click it. I'm trying to do .setCancelled(true) on the PlayerInteractEvent but it doesn't stop the inventory from appearing?

[limber owl]

please

[quaint mantle]

The Static member approach is just a simple an easy solution. There're definitely more elegant patterns to have the job done, like using dependency injection.

[humble tulip]

what's the value of size?

[limber owl]

I'm going to sleep, you found the problem that I've been working on for 1 and half a hour in minutes, it's 2am and Im tired, sorry

[lethal python]

ok so i will use this code instead, i want to cancel the inventory appearing if the player is sneaking

if (player.isSneaking()) event.setCancelled(true);

surely that would work

that's what i have

[humble tulip]

Is it an inventory open event?

Close the inventory

Don't cancel

[lethal python]

make an int called count = 0 and a string called last = null, iterate thru the stringlist and check if the current string = last, if it does increment count by 1, if it doesn't equal it then set count to 0, return current string if count reaches 5

[lethal python]

it's a PlayerInteractEvent

[humble tulip]

^^

I'm proud

[lethal python]

why

[humble tulip]

U gave him an algorithm

Just retun no need to cancel

[lethal python]

i got a B in algorithmics

[humble tulip]

Niice

[lethal python]

my problem still : (

[humble tulip]

Just don't open it for them?

And return

[lethal python]

nono

i have this item which i have detected if they're holding

[humble tulip]

Yes

[lethal python]

i need to check if they are crouching

if they are, and they're right clicking a block which is in my list of forbidden blocks, then i need the inventory to not open

i mean i cancel the event at the end anyway idk why im actually checking again

i always cancel the event

but the inventory always opens

[humble tulip]

when u want to exit the method use return;

So do ur checks to not open the inv and return

[lethal python]

that won't cancel the inventory opening

[humble tulip]

I dont understand why it won't

[lethal python]

returning from an event handler won't cancel the event

[humble tulip]

U don't have to cancel it

Just don't open the inv

[lethal python]

but i'm not opening the inventory

if the player right clicks a barrel

[humble tulip]

So why does the inv open?

[lethal python]

i don't want the barrel to open

[humble tulip]

Well cancel tje event first

[lethal python]

i did that

it isn't stopping the barrel from opening

[humble tulip]

Can i see ur listener?

[lethal python]

https://i.imgur.com/HBSBIkc.png

the final line there is supposed to make it so if you right click while crouched, the barrel won't open

but the rest of the event listener will play out

[humble tulip]

Yep

Set the listener priority to monitor to test if something is uncancelling the event

[lethal python]

how do that :v

[humble tulip]

Next to @EventHandler

(priority = EventPriority.MONITOR

also print somethingafter u check that the data is correct

[lethal python]

so would adding that have fixed it

[humble tulip]

I'm not sure we're testing to see what the problem id

Is

[lethal python]

so what should the monitor have done

the thing i added to check if i was crouching says i am

[humble tulip]

Where did you print the crouch check message tho?

[lethal python]

immediately after the last line in that screenshot

[humble tulip]

MONitor makes your listener code run after all other listeners so u have the final say

[lethal python]

oh well

the barrel still opened

[humble tulip]

Are u sneaking when u right click the barrel?

[lethal python]

yes

[humble tulip]

Use & & instead of & btw

Idk why ur code is bugged

[lethal python]

nop

[fervent gate]

Quick question, for a server that will have a lot of features. What would be the best solution, 1 big plugin or a lot of small ones?

[lethal python]

not using && on purpose

[humble tulip]

You wanna evaluate both?

Why

[lethal python]

i don't want to quit the rest of the event listener if the player is only standing up

they need to be standing up and clicking a forbidden block

[humble tulip]

Doesn't matter too much

[humble tulip]

That's not what && does

[lethal python]

my brain isn't very good today so that might be wrong but it's working

i know && skips evaluating the 2nd one if the first one fails

[dusk flicker]

separate different things

[lethal python]

anyway the event still isn't getting cancelled

[humble tulip]

Yep but that won't quit your listener or anything

[dusk flicker]

ex 1 core plugin, that handles the stuff that would be used on the full network etc; specific plugins for each gamemode, etc

[jagged quail]

im so bad at this

[lethal python]

i saw someone on a forum post say that they cancelled the event when they clicked a dispenser and it worked for them

[humble tulip]

Can i see what blocks are in the list

[humble tulip]

It's supposed to

[lethal python]

https://pastebin.com/vyP6ix6h

[humble tulip]

Try other blocms other than barrel

And make sure you're crouching

[jagged quail]

idk how to use dependency injection

[lethal python]

i am crouching and clicking doors and chests

[humble tulip]

And they still open?

[lethal python]

yes

[humble tulip]

Something is wrong

[dusk flicker]

I somewhat do that

[sterile token]

Arent called MongoDB Pojo's?

[dusk flicker]

I have objects created that will be used for the DB, but methods in that class I have basic save/update/delete methods; its hardcoded -> All it basically is, is converting it to a bson Document

[sterile token]

Yeah

I do that

But i seen that some people dont use bson Document

They directly save/update/delete/etc a class object with properties already defined

Hey, im not really able to figure out what is the problem with my plugin. Is someone able to help me (this is the console when i enable it: https://pastebin.com/SLhtQRKQ)

best guess off a quick look- your command isnt defined in your plugin.yml

https://www.spigotmc.org/threads/beginner-programming-mistakes-and-why-youre-making-them.278876/

I was reading this post and I noticed that I frequently made this mistake in a recent plugin. What would be the correct and efficient way to do the thing that this codeblock does so poorly?

I was making pets and did the exact thing here.

[echo basalt]

I'd honestly just do a weird map supplier type thing

Map<String, Supplier<SpawnPet>> petSupplier = ...;

petSupplier.put("common_cow", () -> new SpawnCommonCow(this.plugin));
etc


String value = container.get(type, PersistentDataType.STRING);
SpawnPet whatever = petSupplier.get(value).get();

whatever.spawnPet(player, 3);

getKeys(true) returns all paths

or recursion

wait so what's your objective?

make a tree view or something?

what if you do getKeys(true) and substring(lastIndexOf(".") + 1)

it's just simpler

[compact haven]

^ it probably does recursion under the hood lol

[golden turret]

is there a way to get a Plugin from bungeecord like bukkit JavaPlugin.getPlugin(Class)?

[subtle folio]

Is there a event for when a entity moves and not just a player?

[ivory sleet]

sadly nope

[subtle folio]

oh heck, is there a way I can check if a mob moves outside of a certain radius or nah?

[golden turret]

but nms have a move method

[ivory sleet]

nope

[golden turret]

inside the Entity class

[subtle folio]

What is the event called?

[golden turret]

i mean

[ivory sleet]

yes but EntityMoveEvent doesnt exist because it had too much overhead

[golden turret]

the Entity class from nms have a method called move

[ivory sleet]

since it would record a timing when the event fired, and the system uses reflection

[golden turret]

but that will only work for custom entities

[subtle folio]

so I cant check if a regular zombie moves somewhere?

[minor otter]

is there a client side block physics event?

[golden turret]

you can do a 1 tick runnable

[subtle folio]

id rather not but alright

[golden turret]

and create a new event bus just to not use the bukkit's one

because it uses reflection

[flat olive]

oh kkill myself

[vital moon]

I've been trying to do public class main extends JavaPlugin but it doesn't find it for some reason

[flat olive]

thats a lot

[ivory sleet]

yeah alternatively reflection

[flat olive]

Okay I did it

but I have a question

how do I build this as a jar

not a folder

https://gyazo.com/b4f33d55c72ceb100fa42b8e1d42c10c

[ivory sleet]

you use the maven tasks

through your terminal prob

or the ui window

[flat olive]

Yeah I see that

[winter nova]

Anyone know some good plugins for trading items with chest that is crossplay compatible like 1 item for another no money system

[flat olive]

do I use maven compile

command

nvm found it

its install

WOAH

https://gyazo.com/967a2eca3303b080016160874792688e

[river oracle]

make sure your plugin.yml has the right path

[vital moon]

it did not create a plugin.yml

[river oracle]

you have to create the plugin.yml

https://www.spigotmc.org/wiki/plugin-yml/

[winter nova]

Anyone know some good plugins for trading items with chest that is crossplay compatible like 1 item for another no money system???

[river oracle]

be patient

jesus christ your annoying

[winter nova]

Who

[vital moon]

how would this help exactly

[river oracle]

you

[winter nova]

Asked

[river oracle]

the plugin.yml contains some info about the plugin like path to main class, description commands etc

 The plugin.yml is a file made to contain information about your plugin. Without this file, your plugin will NOT work. It consists of a set of attributes, each defined on a new line with no indentation.
All attributes are case sensitive. Attributes in bold are required. Attributes in italics are not.```

[vital moon]

yes but I can't even code it thats what my issue is

[river oracle]

the wiki goes over all the fields you need in it

make a file called plugin.yml in your resources folder

[vital moon]

https://gyazo.com/197af758b48b795007792ad76bdf9ae2

[river oracle]

oh you don't have the spigot-api added

do you know much java?

[vital moon]

nah, but know a bit of other languages

https://gyazo.com/295ca780a867961821a2fa807efc7c2c

added both of those

into it

[river oracle]

I'd spend a couple days aquainting yourself with the syntax then that should be really all you need if you have plenty of programming experience already. I also recocmend using a package manager like Maven or Gradle for java projects

[vital moon]

it's also under the "Referenced Libraries"

Im using eclipse with a Maven project already

I learn syntax by coding something

so thats what im doing

[river oracle]

your class naming conventions are slightly off I'd just check out java naming conventions

[vital moon]

I will name them how I like to name them

[river oracle]

https://www.spigotmc.org/wiki/spigot-maven/

[river oracle]

lmao

[uneven fiber]

realest shit i’ve seen in a minute

[river oracle]

I'm putting numbers in my class names now for because I want to

[ivory sleet]

I mean Id advocate naming conventions but ye

[vital moon]

well it's more of the stuff I code its mostly only for me so Im gonna name them how I like to

[uneven fiber]

so called free thinkers when naming conventions and camel case is brought up

[ivory sleet]

yeah well its not the most fundamental thing in the beginning so no shame :3

[vital moon]

yeah rn its just been trying to get the api to actually function but it isn't rn and can't figure out why

[river oracle]

you need to add it to your maven dependencies
https://www.spigotmc.org/wiki/spigot-maven/

^ wiki tells you how to

[vital moon]

stil won't import the API when I try to use extends JavaPlugin

[river oracle]

are you importing it

[vital moon]

it doesn't regconize it

https://gyazo.com/bb635b59aaa65df62e4717550dda3c94

[uneven fiber]

https://www.youtube.com/watch?v=rT-gZeevmZs&t=493s

Could be useful

he walks through the process, may have something

[vital moon]

im already watching one but I'll give that one a look rq

[uneven fiber]

👍

[vital moon]

yeah so a few issues, he's using linux I believe, im on a windows machine and I already tried that software and it didn't work for jack shit so I removed it and am using eclipse

[uneven fiber]

oh your not using intelliJ/jetbeans?

[vital moon]

nah was having issues with it so using eclipses

[uneven fiber]

oh, yeah then I'm not much help

why doesn't it work on your computer?

cause i also have windows

[vital moon]

pretty sure it was something with the java file I had downloaded it using intelij and kept saying it was corrupted and wouldn't continue

[uneven fiber]

rip

[vital moon]

yeah but eclipse works without issue so just went with that

[uneven fiber]

yeah i heard that you can use eclipse, but i never have so im not sure what the issue may be

[flat olive]

how do I make holograms, I want to make a plugin to do /npc hologram <line> <message>

[uneven fiber]

for spigot at least

[shut field]

how can I send a string between a Waterfall plugin and my server plugin?

[quaint mantle]

Im making a care package plugin and im just trying to figure out how i can make the care package spawn ON surface, im randomizing the x,y,z but i want the package to be on surface and if its meant to spawn in a ocean/over water, itll restart the randomization

[summer scroll]

You need to do like a simulation, get the surface location and check the block

[flat olive]

how do I access the second argument the user sends

for a command

args[0]?

nvm I figured it out

[shut field]

second is args[1]

third is args[2]

[minor otter]

Is there a packet associated with tripwire client predictions

[quaint mantle]

im sorry, i geniunely have no idea how i should do that at all, im still new to spigot plugins ngl

world.getBlockAt(gen_x, 100, gen_z).setType(Material.CHEST);

So how can I put some contents into this chest?

[flat olive]

https://gyazo.com/01afe430dea048ab9f1177f9bb215f43

whenever I type in /hologram t

its saying what I used for if the length of args is above 2

length of args array

it makes no sense

why is it sending when the arg is 1

[quaint mantle]

can you send an ss of what it sends in game?

[flat olive]

its exactly what my message is

Please use /hologram <message>

/hologram t

[quaint mantle]

ah, okay i got it

[flat olive]

oh

my

GOD

I meant to use a greater than sign

but I used less than

nvm im dumb

[quaint mantle]

its mostly how i access the inventory for this chest, i know how to put stuff in

[earnest forum]

do .getState() on it

and then cast it to a Chest

then from that you can do Chest#getBlockInventory()

[quaint mantle]

yeap no idea, what exactly am i doing .getState on? ofc its not on the code i sent above so kinda at a loss atm

[earnest forum]

on the block sorry

Block block = world.getBlockAt(x,y,z);

if (block.getState() instanceof Chest){
  Chest chest = (Chest) block.getState();
  Inventory inv = chest.getBlockInventory();

}

@quaint mantle

[flat olive]

does anybody know how to make new lines for hologram custom names

[earnest forum]

you can't

just have to make a new armour stand

[flat olive]

bro what

I mean new lines as in

lines that go over again

[earnest forum]

the plugin holograms?

[flat olive]

no

I mean like when you enter text in

one line

two lines

this is the first line
this is the second line below it

\n

[earnest forum]

yes

you make a new armour stand for each line

armour stand 1 name = line 1
armour stand 2 name = line 2

offset them on the y coordinate a little bit

are you programming a plugin or using someone else's

[flat olive]

so if user args[0] == line number for whatever user sends the command make a new armorstand and offset its value in the same location the previous hologram was but make its y coordinates minus a few values?

Making my own plugin

[earnest forum]

yep

[flat olive]

okay

sounds hard as shit

🤣

[earnest forum]

oh wait

so when the text gets too long you want it to automatically go to the next line?

[minor otter]

Is there a way to get client block update packets?

[flat olive]

no I just want other to be able to do /hologram 1 test 2 another

and in coding logic

print("test"\n"another")

[earnest forum]

looking at how other plugins do it

you create a hologram which is stored somewhere with a name

and then you set each line of it with a separate command

/createhologram "test"

/changehologramline "test" 1 "this is line 1"

/changehologramline "test" 2 "this is line 2"

[flat olive]

wait

instead ill do /hologram a b c

so arg 1 which is a will be line 1
b is 2
c is 3

ill automatically make whatevers next on the next line

that way its not so complicated

[earnest forum]

but then you can't have sentences

[flat olive]

oh

[earnest forum]

because a space in the command

[flat olive]

oh my god

[earnest forum]

makes it a different argument

[quaint mantle]

            int min_xpos = -3000;
            int max_xpos = 3000;
            int gen_x = (int)Math.floor(Math.random()*(max_xpos-min_xpos+1)+min_xpos);

            int min_zpos = -3000;
            int max_zpos = 3000;
            int gen_z = (int)Math.floor(Math.random()*(max_zpos-min_zpos+1)+min_zpos);
            Block block = world.getBlockAt(gen_x, 100, gen_z).setType(Material.CHEST);```
"Incompatible types. Found 'void', required org.bukkit.block.Block"

*pain*

[earnest forum]

setType doesnt return anything

 Block block = world.getBlockAt(gen_x, 100, gen_z);
block.setType(Material.CHEST);

@quaint mantle

[quaint mantle]

oh

great

yeah that makes sense

[flat olive]

how do I get whatever is in the first argument and whatever ends off the last bit of the argument

args[0:-1]?

or is it args[-1:0]

[ivory sleet]

no java doesnt have that

[flat olive]

wtf?

js

and python do

[ivory sleet]

yes

[flat olive]

bro WHAT

[earnest forum]

java isnt js and python

[flat olive]

how can I do that thne

[earnest forum]

if you want to get the last argument you get the length of the args array and then subtract it by 1

[river oracle]

for loops!

or just basic math

[earnest forum]

are you trying to combine arguments?

[ivory sleet]

generally java doesnt add unnecessary language features

[somber hull]

Lmao

[ivory sleet]

I mean they only add features if proper motivation is given else than arbitrary usefulness

[flat olive]

how would I setcustom name to all the args they provide instead of just one

[earnest forum]

for loop

[flat olive]

I cant use for loops ?

[quaint mantle]

Im making a care package plugin and im just trying to figure out how i can make the care package spawn ON surface, im randomizing the x,y,z but i want the package to be on surface and if its meant to spawn in a ocean/over water, itll restart the randomization

i am an extreme beginner so if you guys do know, please dumb it down a lil lol

[flat olive]

hologram.setCustomName(ChatColor.RED + args[0]);
I cant use a variable and keep adding onto it and setting it

[somber hull]

There’s a method for it

Lemme find it

Your trying to find the highest solid block right

[quaint mantle]

more or less yeah

[sour brook]

StringBuilder?

[quaint mantle]

i want it to spawn on any available block but not inside of one

[earnest forum]

world#gethighestblock(x,z) I think

[somber hull]

That one

Yea

It’s

[tranquil viper]

Is Bukkit.getServer().broadcast() supposed to be deprecated?

[somber hull]

getHighestBlockAt(x, z)

[sour brook]

StringBuilder builder = new StringBuilder();
for(int i = 1; i < args.length; i++) {
builder.addend(args[i]);
}

[somber hull]

@quaint mantle

[quaint mantle]

im gonna try it out

[tranquil viper]

And it requires a message & permission but it's @NotNull so putting null as the permission isn't going to work, right? I don't remember this being the case but Ig it is now?

[ivory sleet]

yes

if its paper

since they favor adventure

[tranquil viper]

Oh I forgot I'm using paper for this project, nevermind

Whilst you're here though, what should I put for the permission if I want it to be null?

[ivory sleet]

uh

broadcast is permission based

[tranquil viper]

Within paper using a string yes

[quaint mantle]

it worked! tyvm

[somber hull]

Np

[tranquil viper]

Whatever I'll just go learn how to do it the way they want me to

Even though I'll probably never use paper again

[ivory sleet]

use Bukkit.getServer().sendMessage() if you wanna do it without permission

(paper only)

[quaint mantle]

so my next and hopefully last question for a while is, how can I make an armorstand and make it spawn at an exact location? this goes hand in hand with the care package

[tranquil viper]

Only accepts Components, just going to learn how to use components for now

[ivory sleet]

Component.text("blah")

[tranquil viper]

I've used them briefly in the past but I lowkey forgot

[tranquil viper]

That easy huh

lmfao

thank you very much

[ivory sleet]

with styling it gets a bit more intricate

but ye

[sour brook]

World#spawnEntity(EntityType.ARMOR_STAND) Or Use NMS

[quaint mantle]

yes but it needs to spawn at an exact set of coordinates, ive randomly genned a set and need it to spawn there

[earnest forum]

spawn entity has location argument

[quaint mantle]

ah yep im dumb

[gleaming olive]

wdym subtract health ? I dont want double damage, i just want double attack speed..

[flat olive]

it doesnt include spaces

[earnest forum]

Pretty sure you have to have modified jar

might be some way to do it with nms

[gleaming olive]

aw

nms o:

ok il'l try that

[sour brook]

What

[earnest forum]

Add a " " after

[flat olive]

I am

trying rn

to do that

[sour brook]

Oh yes sorry Xd

[quaint mantle]

Location location = new Location(gen_x, 100, gen_z);```
im misunderstanding something here :thonk:

[sour brook]

StringBuilder builder = new StringBuilder();
for(int i = 1; i < args.length; i++) {
builder.addend(args[i] + " ");
}

[flat olive]

Nice that works

now I need to figure out the super hard part

different lines

I think I want to make a specific system for this

after the hologram armor stand is made give them a random generated ID

they can take that id and add a line to the hologram, what it does is make a new hologram with whatever text in the same location as the hologram given (the id given) just subtract y value some

[sour brook]

You can do this by spawning the upper armor of the lower armor of the lower stand

[quaint mantle]

Location location = new Location(player.getWorld(), gen_x, world.getHighestBlockYAt(gen_x, gen_z), gen_z);
            world.spawnEntity(location, EntityType.ARMOR_STAND);```
This code spawns it perfectly, now how can i make my armorstand invisible and give it a name? im not sure how to access the armorstand itself

[earnest forum]

store the entity when you spawn it

Entity e = world.spawn....

you can then cast it to ArmorStand which has cool stuff

[quaint mantle]

i saw a ArmorStand class too, would that work too?

oh

[earnest forum]

yea

[flat olive]

ArmorStand hologram = (ArmorStand) player.getWorld().spawnEntity(player.getLocation(), EntityType.ARMOR_STAND);
                hologram.setGravity(false);
                hologram.setVisible(false);
                hologram.setCustomNameVisible(true);

thats for you

anyways

[sour brook]

armorStand.setVisible(false);

[flat olive]

how can I make this an NPC

instead of armor stand

[earnest forum]

nms

[flat olive]

what is nms

[sour brook]

One hard

[earnest forum]

basically mojang's code

spigot is an API which builds on mojang's code and makes it easier

[sour brook]

Net.Minecraft.Server ...

[earnest forum]

it's basically packets

[flat olive]

so... can I just make an npc in the same location the armor stand gets created at?

[earnest forum]

you can Google player npc tutorials on YouTube

you basically have to make a fake player

[flat olive]

right

[sour brook]

Ye

[earnest forum]

I'm on phone and I think teixayo is too so it's probably best to look up a tutorial

[ivory sleet]

Use citizens

[quaint mantle]

ArmorStand entity = (ArmorStand) world.spawnEntity(location, EntityType.ARMOR_STAND);
            entity.setCustomName(ChatColor.translateAlternateColorCodes('&', "&l&cCARE PACKAGE!!!"));

it spawns but it doesnt have the custom name..

[compact haven]

entity.setCustomNameVisible(true)

[quaint mantle]

oh my bad didnt see it

[tranquil viper]

    public void particilizeAirdrop(Location airdropLoc) {

        Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {

            int i = 10;

            @Override
            public void run() {
                if (i <= 0) {
                    Bukkit.getScheduler().cancelTask(how to get the task id);
                }

                airdropLoc.add(0, i, 0).getWorld().spawnParticle(Particle.FIREWORKS_SPARK, airdropLoc.add(0, i, 0), 8, 0.2F, 0F, 0.2F);
                i--;
            }
        }, 0, 10);
    }

I have this method that particilizes an airdrop, but I'm not sure how to cancel it after it runs 10 times. I don't want to create a variable outside the loop because then it would be replaced if someone places a different airdrop and the task would never be cancelled. Any ideas?

[quaint mantle]

so ive got a chest, how can i add an item with something like efficiency 6 or protection5 to the chest?

[tranquil viper]

Make an ItemStack[], add the item you want to the array, then set the contents to the array

Or just make an ItemStack and add it to the chests inventory

Either way works

[quaint mantle]

main issue im facing is getting the item enchanted

how can i make it an enchanted item

[chrome beacon]

Call addEnchantment on the item stack

Or addUnsafeEnchantment if you want to enchant highee levels

[quaint mantle]

oh thank god you told me about unsafe

and does anyone have a little guide on how to make custom enchants?

[earnest forum]

I honestly wouldn't go down that path

it's really bad

[quaint mantle]

yeah me neither, i decided against it

[earnest forum]

I recommend making your own enchantment system

[quaint mantle]

and is there a like PlayerAttack event? for when a player hits an entity

[earnest forum]

EntityDamageByEntityEvent

check if the Damager is a player

[tranquil viper]

Recommend adding lore that contains the custom enchants if possible, you can make a pretty simple system like this

[chrome beacon]

It's still really messy to deal with

Highly recommend using an already existing plugins api

[tranquil viper]

It's a fun project and you learn a lot from it

[chrome beacon]

It's fun until you realize how creative mode works

[tranquil viper]

Have you tried AsyncPlayerPreLoginEvent?

[woeful moon]

It's a little more complicated than that, I need to get it outside of any event

where I only have the Player object

[chrome beacon]

?scheduling

[undone axle]

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

[tranquil viper]

Ok so here: Store it in a database or something when a player logs in, then you can just access the database to get the ip

[tranquil viper]

I highly recommend storing with UUIDs over names or anything else though

[woeful moon]

Thanks for the tip

[chrome beacon]

There can be multiple players with the same name

It will break stuff

[tranquil viper]

That's why I just said to use uuids :p

[chrome beacon]

Yeah just explaining why

[tranquil viper]

Ah, also all the methods using BukkitRunnable are deprecated?

[chrome beacon]

No

You should just use the BukkitRunnable directly

[tranquil viper]

ohhh

I see now

That's what I get for coding at 12am lmao

thank you

[chrome beacon]

Sleep is important

[tranquil viper]

Indeed

I'm in one of those periods of time where I just can't stop coding

Then I'll get burned out in a few months ago

It's a whole cycle at this point

[brittle lily]

Hey Guys I'm making Warp Plugin and I wanna make warp list command How can I get Warps name from config?

[tranquil viper]

string lists

configuration sections

few different ways to do it tbh

[heady pumice]

Im a bit confused about how to properly depend on another one of my plugins.
I thought i always need to get the plugin instance by doing PluginManager.getPlugin etc etc or whatever.
Braindead i wrote it like PluginMainClass.getWhatever and it works fine, is that intended or did i just not get far enough to encounter issues?

[little panther]

Hey, im kinda new to coding and trying to learn hashmaps for a plugin. Is there a way to sort information after value to make a leaderboard?

[quiet ice]

Now that is a complicated problem

[heady pumice]

You can loop through HashMaps, and then probably use any sorting algorithm

[quiet ice]

Generally you wouldn't want to use HashMap but rather LinkedHashMap for displaying the sorted key-value pairs

And then sort the linked hashmap through clearing the whole map and inserting the elements in their sorted order

[little panther]

do you have some sort of example, sorry if thats too annoying to get 😄

[quiet ice]

In one of my plugins I instead use TreeSet using a custom immutable datatype that stores player UUID and player score - however it's #equals and #hashcode operations are rigged to only compare UUID where as the compareTo compares only the score. You'd need to delete and reinsert the datatype to update the score however and I am not overly sure if that really works since I have only used that approach in plugins I use for my own server which is pretty much empty

https://github.com/Geolykt/bake/blob/master/bake/src/de/geolykt/bake/Bake_Auxillary.java#L159-L174 is the first algorithm I described (which uses a seperate map)

(Don't comment on the rest of the code - I know that it is absolutely trash)

[little panther]

im new to coding, so for me its surprising what you are able to do :)

but yea, i think i get what you have done

[iron glade]

Any idea why this keeps teleporting me into the ground like this?

Location newLoc = p.getLocation().clone().add(xDistance, 0, zDistance);
p.teleport(newLoc.getWorld().getHighestBlockAt(newLoc).getLocation());```

[quiet ice]

Probably because it is the highest block but that will still be non-air (you'd need to add 1 to y to get the air block)

[iron glade]

So I'd have to add (0, 1, 0) to land on top of it

alright

[quiet ice]

Most likely

[iron glade]

Is there a reason I'm always facing the same direction event though setting the yaw randomly

[sacred mountain]

yaw randomly between what values

[iron glade]

-180 to +180

[sacred mountain]

ok should work idk

[iron glade]

always facing 0 (south)

        Random r = new Random();
        float randomYaw = -180 + r.nextFloat() * 360;

        Location newLoc = p.getLocation().clone().add(xDistance, 0, zDistance);
        newLoc.setYaw(randomYaw);```

[sacred mountain]

and yeah getting the highest location will put you in the block

so add 1

[iron glade]

yes done that

works fine now

[sacred mountain]

alr

r.nextFloat(min, max)?

or is that not a thing

[brittle lily]

How can I string of String Path?I will save a many warps. and I wanna make list of them. How can I get String of their name

[sacred mountain]

im not sure what the -180 * r.nextFloat() stuff is

[iron glade]

it's basically the same formula to set bounds

min and max

min + r.nextFloat() * (max - min)

[iron glade]

but yeah that's more comfortable to use

the generated values are fine, but it's not setting them

[sharp kayak]

sure wahts up

[dreamy arrow]

Wait let me post the logs

[drowsy helm]

oh just make the set public and access it from the PlayerQuitevent

[earnest forum]

PlayerQuitEvent?

or make a method

[dreamy arrow]

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

there is an error

[jagged quail]

so make this public?

and maybe move the @Override up

[drowsy helm]

yeah

nah leave the override

[earnest forum]

store an instance of the class too

dont wanna make 2 different hashsets

[drowsy helm]

what are your params

[dreamy arrow]

java -jar BuildTools.jar --rev 1.8.8

[jagged quail]

1.8.8 is unsupported

            flyingPlayers.remove(player.getUniqueId());
        }
        return true;
    }
}
``` how would this make 2 hashsets?

[quaint mantle]

no

dont make it public

[jagged quail]

meant to reply to you

[quaint mantle]

public variable bad

public variable mean can be reassigned

dont do that

[dreamy arrow]

heh wdym? buildtools for 1.8.8 is still listed in wiki

[earnest forum]

when yous et the command executor store the instance of the new class

[dreamy arrow]

https://www.spigotmc.org/wiki/buildtools/

right in here

[jagged quail]

yeah but it's not supported though

your basically on your own if you have issues unless people want to help

[dreamy arrow]

but worked on my ubuntu system. buildtools isnt installing on main system

[jagged quail]

what java version do you have

[dreamy arrow]

java 8

[jagged quail]

do you have git installed?

[dreamy arrow]

u mean git bash?

ye

[jagged quail]

hm

well it should work then

[dreamy arrow]

there is a java runtime rror

[jagged quail]

send the log in

[dreamy arrow]

i even tried installing latest on windows with latest java still doesnt work

[jagged quail]

?paste

[ERROR] I:\Developement\BuildTools\CraftBukkit\src\main\java\net\minecraft\server\DedicatedServer.java:[1] The type org.apache.logging.log4j.util.Supplier cannot be resolved. It is indirectly referenced from required .class files```

try deleting buildtools and download it again

[iron glade]

Nevermind, got it working now

        Random r = new Random();
        float randomYaw = r.nextFloat(-180, 180);

        Location newLoc = p.getLocation().clone().add(xDistance, 0, zDistance);
        p.teleport(new Location(newLoc.getWorld(), newLoc.getX(), newLoc.getWorld().getHighestBlockYAt(newLoc), newLoc.getZ(), randomYaw, newLoc.getPitch()).add(0, 1, 0));```
.getHighestBlockAt(loc).getLocation() seems to return a locatino with yaw and pitch = 0, that was the reason I think

[dreamy arrow]

yep tried 5 times already

even switched to windows power shell

same error

[jagged quail]

maybe build it on your ubuntu system and transfer it to your pc

is the ubuntu system a vps or local system

[dreamy arrow]

then how am i gonna use it. it wouldnt be in my local maven repository

[jagged quail]

for intellij?

[dreamy arrow]

its hosted on a virtual box

hmm

wot to do :v

[jagged quail]

put this in your repositories <repository> <id>spigotmc-repo</id> <url>https://hub.spigotmc.org/nexus/content/repositories/snapshots/</url> </repository>

[dreamy arrow]

oh

wait can i even access nms

[jagged quail]

then this in dependencies <dependency> <groupId>org.spigotmc</groupId> <artifactId>spigot-api</artifactId> <version>1.8.8-R0.1-SNAPSHOT</version> <scope>provided</scope> </dependency>

[earnest forum]

yes

change spigot-api to spigot

[jagged quail]

doesn't intellij download it automatically for you?

[earnest forum]

no

spigot-api only includes what spigot builds on top of nms

[jagged quail]

i have this

[earnest forum]

you have to install that i think

its an intellij plugin

[jagged quail]

yes

[earnest forum]

because i havent got that

[jagged quail]

i did that

[dreamy arrow]

its already like that but i can't access nms

[earnest forum]

change spigot-api to spigot

artifactId

[opal juniper]

You need build tools to install the nms to local yes

what error are you getting?

[dreamy arrow]

did

org.spigotmc:spigot-parent:pom:dev-SNAPSHOT was not found in https://hub.spigotmc.org/nexus/content/repositories/snapshots/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of spigotmc-repo has elapsed or updates are forced

[sacred mountain]

i suppose it's fixed now?

[dreamy arrow]

like when installing>?

[opal juniper]

yes

[dreamy arrow]

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

[iron glade]

yes, see above for solution

[dreamy arrow]

thats the error log

[opal juniper]

hmmm thats weird

[dreamy arrow]

ik

oops caps

it installed on my ubuntu system perfectly

but in win10

[jagged quail]

@dreamy arrow install the plugin

on intellij

[dreamy arrow]

I DID

:V

oops caps

breh

[jagged quail]

this one?

[dreamy arrow]

hmm

i am going for nms not normal spigot

[jagged quail]

nms?

[dreamy arrow]

when u install buildtools it puts nms on ur local repository

[jagged quail]

ah

[dreamy arrow]

net.minecraft.server

[jagged quail]

oh

you are running it in git bash?

[dreamy arrow]

HMM

oops caps

breh this capos

[vale ember]

how can i get the base value of any Attribute?

[sacred mountain]

the default?

theres a thread on that

https://www.spigotmc.org/threads/override-base-item-attribute-value.236434/

might help you

i dont think the spigot api has it

but then again its been like 4-5 years

[opal juniper]

that doesnt change it

why do you keep saying this

[thorny dawn]

can someone help? i am getting kotlin.UninitializedPropertyAccessException: lateinit property plugin has not been initialized in my dependancy injection]

[jagged quail]

ok i need to figure out how to make it remove the player from the hashlist when they leave

[quiet ice]

Listen for the PlayerQuitEvent (or however it is called)

[jagged quail]

in the main class?

[brittle lily]

?paste

[undone axle]

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

[thorny dawn]

Bukkit.getScheduler().runTaskLater(Bukkit.getServer().pluginManager.getPlugin("Mobwars")!!, Runnable {}, 20) is this a good way to delay execution?

[earnest forum]

new Runnable

[thorny dawn]

kotlin

[earnest forum]

ah

idk

[thorny dawn]

the syntax is correct

im asking if the logic is correct

[earnest forum]

should work yeah

realistically should be using di for the plugin

[thorny dawn]

its a bit complicated to do in kotlin

at least i haven figured out with my knowledge

[earnest forum]

what does !! do

[quiet ice]

!! or what?

[thorny dawn]

it assures that the plugin is not null

"?" means nullable and "!!" means not null

[earnest forum]

ah

[quiet ice]

Basically an Objects.requireNonNull, right?

[thorny dawn]

probably, not familiar of how it would be done in java

[quiet ice]

But yeah, I think this logic is right

[thorny dawn]

hm for some reason its not waiting before executing in my for loop

[quiet ice]

Are you sure that you are using runTaskLater?

[thorny dawn]

yeah

[jagged quail]

ok so i have this so far

[quiet ice]

Yank up the delay I guess, it might be too slow for you to notice the difference

[jagged quail]

i cant import that because it's private

should i make it public?

[earnest forum]

u should maybe make it static

since you only will have 1 set ever right

[jagged quail]

private final static

[earnest forum]

public

[jagged quail]

    private final static Set<UUID> flyingPlayers = new HashSet<>();

    @Override

    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        if (!(commandSender instanceof Player)) {
            Msg.send(commandSender, "&cThis command can only be used by players.");
            return true;
        }

        Player player = (Player) commandSender;
        // Enable/disable fly mode
        player.setAllowFlight(flyingPlayers.add(player.getUniqueId()));
        if (player.getAllowFlight()) Msg.send(player, "&aYou can now fly!");
        else Msg.send(player, "&cYou can no longer fly!");
        if (!player.getAllowFlight()) {
            flyingPlayers.remove(player.getUniqueId());
        }
        return true;
    }```

[earnest forum]

you could make it public or make a static method which removes it

public static void removePlayer(UUID uuid){
remove from set
}

[quiet ice]

...

[earnest forum]

sorry im rushin

and ive never actually used a set idk if you use .remove on it lol

[jagged quail]

dont think that'll work

need to change it abit probably

[earnest forum]

oh my god

remove from set is not valid code

i just put it there as placeholder because i was rushing

[iron glade]

Anyone knows a way to get a random color code? java ChatColor.getByChar(Integer.toHexString(r.nextInt(16))) isn't working anymore for me

[earnest forum]

flyingPlayers.remove(uuid)

put that in there

[earnest forum]

whats the error

[earnest forum]

wait

can u show the whole code

[jagged quail]

package me.oliver193.mecha.commands;

        public static void removePlayer(UUID uuid) {
            flyingPlayers.remove(player.getUniqueId());
        }
    }
}

[earnest forum]

dont put the method inside the onCommand

do you actually know how to code in java

[jagged quail]

not really .-.

i'm just trying for the first time

[earnest forum]

you should probably learn

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[earnest forum]

helps a lot

[jagged quail]

yeah

[thorny dawn]

Bukkit.getScheduler().runTaskLater(Bukkit.getPluginManager().getPlugin("Mobwars")!!, Runnable {}, 20) its still not waiting execution

[dreamy arrow]

:V breh its been 3 days and i still cant fix this problem

[sharp flare]

is looping a map entry set in a block break event a bad idea

[quiet ice]

Just note that the code getting called is within the runnable
