[smoky oak]

ah still any clue it works with 1.16

[eternal oxide]

supplying the folder as a Javadoc location it expects an unzipped javadoc set of folders. You need to set a jar location not a directory

[woeful crescent]

How do I detect a player holding right click

[eternal oxide]

You can detect the right click, you can;t detect holding

[ivory sleet]

You could with an invisible armor stand

Altho hacky workaround

Prone to bugs

[woeful crescent]

I know Mineplex does it

for the sniper rifle in super paintball

[ivory sleet]

Yeah but then you hold in an item

[woeful crescent]

huh?

[ivory sleet]

I am pretty sure you hold in an item while performing the holding click

[woeful crescent]

Hold in an item?

[ivory sleet]

In which detecting a holding click is possible

[smoky oak]

actually @eternal oxide , @ivory sleet ...
It's possible, just give me a moment to check the relevant cocde

*code

[hybrid spoke]

as i already said -> store the MSs between each click and compare them. if they are each time 199-201 ms apart, the player is probably holding right click

[ivory sleet]

You can check a holding click through hacky PlayerInteractEvent and some other events but it’s a workaround

[woeful crescent]

hmmmm

[ivory sleet]

Not really a supported way of doing it

[woeful crescent]

maybe I won't

Maybe I'll make it so it activates on right click and cancels if you scroll off of it

[hybrid spoke]

.....

[ivory sleet]

That said you will be introduced to a lot of things which might break that

[smoky oak]

public void onPlayerInteract(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        if ((event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK)){
                ItemStack s = player.getInventory().getItemInMainHand();
}```

[hybrid spoke]

there is the solution. other workarounds are redundant

[ivory sleet]

That’s a single click

Not a holding click

[eternal oxide]

That only detects a Click, it doesn;t detect Holding a right click

[smoky oak]

i see

[hybrid spoke]

i'm feeling ignored

[woeful crescent]

Here's what I'm making:

[eternal oxide]

"No one puts God in a corner!"

Film quote if you were wondering

[hybrid spoke]

for what do you need the rightclick here?

holding rightclick*

[eternal oxide]

It sounds like he's tryign to do a sniper scope on held right click

I wonder if the spyglass events could do that

[smoky oak]

In that case, @hybrid spoke 's solution might actually be the best. The javadoc states that the event fires under specific circumstances which translate to 'event gets triggered ~ once/15 ticks, or with every right click', but from what i can see checking the duration without specifically storing it elsewhere is not possible

[eternal oxide]

There are no spyglass events yet, but possibly

[hybrid spoke]

[smoky oak]

From experience, a map is a far better solution than the stuff with armor stands. That would trigger a different event (PlayerInteractWithEntity) but pure code that has to NOT run on the server (directly) is much faster

[woeful crescent]

I know @hybrid spoke you're feeling ignored, because to be honest, with my current system, it'd be pretty hard to do that. I wanted to make it so you had to hold right click (it'd be pretty OP if you could do other things while rejuvenating), but I think I'll make it so that you click it once, and then you can't scroll off of the item or else it will cancel the rejuvenation.

[hybrid spoke]

already had this topic because of my anti autoclicker plugin since holding rightclick causes 5 cps

[smoky oak]

guys.

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerItemHeldEvent.html

[proud basin]

is it possible to get the top kills with Statistics.PLAYER_KILLS

[hybrid spoke]

its not pretty hard to do that. not even to integrate it. just checking if he scrolls off would actually be more work ig

[smoky oak]

well if he wants to keep it active until item in hand changes

[hybrid spoke]

use a map and sort it by the value

[smoky oak]

just log that he right clicked and set it to false when that events triggers

[proud basin]

ok so it is then

[stoic osprey]

How can I copy a world folder into my plugins directory?

[hybrid spoke]

the integration would probably be the same by having a boolean if he still clicks/holds it or not

[quiet hearth]

Ok so I have an interface that is opened that displays crafting recipes. The interface is opened via a Knowledge_Book, and it is name and has a lore, and is enchanted with luck for the enchanted effect... However when i open the book it displays an error in the console. https://hastebin.com/gokuluheti.rust
I was wondering if there was a way to bypass this.?

[smoky oak]

@stoic osprey per plugin or manually

[stoic osprey]

i.e From ./world to ./plugins/myPlugin/world

[stoic osprey]

plugin

[smoky oak]

Look up how java works with files

there should be a copy method

[stoic osprey]

I tried it

it said the target dir already exists

but it doesn't?

[smoky oak]

...mind jumping in a vc for that?

[stoic osprey]

I can't VC sorry

I can DM though

[smoky oak]

fair enough

[ivory sleet]

Files.copy(world.getWorldFolder().toPath(), plugin.getDataFolder().toPath().resolve("world")) or smtng

[quiet hearth]

Just curious, if u know a way to bypass id appreciate it

[quaint mantle]

Can someone help me with Json onEnable/onDisable please, cant make it work

    public void onDisable() {

        Map<UUID, Collection<Vector>> map =Territory.getAllTerritories().asMap();
        Gson gson = new Gson();
        String json = gson.toJson(map);


    }```

so I have this but it's onDISABLE

[ivory sleet]

Why not use a Multimap

[quaint mantle]

I actually have a multimap

but I read that I must turn it into a Map for json

[ivory sleet]

Also you need to write that into a file

[compact haven]

that is broken

you need to write it to a file like conclure said

[quaint mantle]

yea no idea what i'm doing actually lol

[compact haven]

and use GsonBuilder instead

[ivory sleet]

I believe Gson adds guava collection type adapters by default

Or yeah mb that’s the builder

[quaint mantle]

wdym adding it to a file ? another class ?

[compact haven]

no writing it to an actual file

[quaint mantle]

sorry guys im big noob about it

[compact haven]

it doesnt just stay in memory after restart

[ivory sleet]

No you need a file to store the data like between arbitrary server instances

[quaint mantle]

ah ok so I need to create a "json" file with the name I put it when I call json command, right ?

wait

the file must be in the server

not in the plugin

[compact haven]

https://github.com/Itzdlg/RegenBlocks/blob/master/src/main/java/me/schooltests/regenblocks/RegenBlocksAPI.java#L42
this shitty plugin of mine has an example of reading json

but you need write, one sec

[quaint mantle]

ah thanks will look into it see if it helps

[compact haven]

its something like toJson(object, filewriter)

so just create a filewriter

[quaint mantle]

Im really confused

so 1st of all I need to write in my plugin a command that will create a file in the server disk, right ?

[ivory sleet]

yes a physical file

[compact haven]

public static final Gson GSON = new GsonBuilder()
            .setPrettyPrinting()
            .enableComplexMapKeySerialization()
            .disableHtmlEscaping()
            .create();

...
try {
    File file = new File(dataFolder, "territories.json");
    FileWriter fw = new FileWriter(fw);
    GSON.toJson(Territory.getAllTerritories().asMap(), fw);
} catch (IOException e) {
    e.printStackTrace();
}

[quaint mantle]

ok is there any spigot thing to do that ?

hmmm

[ivory sleet]

Just use a FileWriter

Like itzdlg showed you (:

[quaint mantle]

damn tysm dude, so it s tailored to my thing already like that ?

what does it do

[compact haven]

well dont just copy it, learn what it does

[quaint mantle]

yea

[compact haven]

the first part creates a static object called GSON, all static final constants should be uppercase by convention

[ivory sleet]

Your plugin might leak memory if you copy paste that code considering that it doesn’t close the file writer.

[compact haven]

then we create a builder for the Gson object, enable pretty printing which puts different keys on new lines, enables map key serialization which serializes map's properly, and disables html encoding which prevents your json from being fucked up

you should use that new Gson object everywhere, dont copy paste that code to every file you use gson in

[quaint mantle]

hmm okay so all those methods are Gson methods, like the core methods of Gson to copy my shit into json file, right ?

[compact haven]

thats why it's statically available

now we create a try catch which is for FileWriter

because it throws IOException in some odd cases

then simply toJson serializes the object to a json string and then writes it to the FileWriter (fw) provided

[quaint mantle]

hmm

so

File file = new File(dataFolder, "territories.json");

this create an actual file in a folder somewhere ?

[compact haven]

dataFolder needs to be your plugin data folder

so get the instance of your plugin then call #getDataFolder()

[eternal garnet]

Is there a way to check of the message author is a player or a bot? If yes, can someone please give me an example?

[compact haven]

event.getMember().isBot()

[quaint mantle]

My plugin has no folder being created when you load it into a server is that what is meant

[compact haven]

I'm assuming you mean JDA since you give no information at all

[eternal garnet]

oh shit wrong dc server

soryy

[compact haven]

if it is JDA

then that line I gave works for u

[quaint mantle]

do I need to create a such a thing ?

[eternal garnet]

It's javacord

[compact haven]

oh

[hybrid spoke]

lmao

[compact haven]

never used javacord

[ivory sleet]

JDA all the way (:

[hybrid spoke]

^

or python

[ivory sleet]

Jython 🥴

[hybrid spoke]

BrainCord

DiscFuck

would be a huge lib

for brainfuck

[compact haven]

I'd love to see how you can make an http request in assembly

kekw

[ivory sleet]

🥲

[quaint mantle]

if (!getDataFolder().exists()) getDataFolder().mkdir();
saveDefaultConfig();

will this create a datafolder ?

[ivory sleet]

yes

[quaint mantle]

thanks

[chrome beacon]

You don't need to create the data folder it will do that for you

[quaint mantle]

thanks guys really appericiate the help!

[hybrid spoke]

isnt the data folder pregenerated?

[quaint mantle]

it doesnt for me

Ive been loading my plugins many time

[ivory sleet]

I think not in older versions

[quaint mantle]

no datafolder

[chrome beacon]

Oh

[quaint mantle]

not sure what is meant by older version but ive downloaded all this shit recently so

maybe only some IDE do that

[hybrid spoke]

no IDE does that

[chrome beacon]

IDE doesn't have anything to do with this

[quaint mantle]

what does then ? isnt it from templated code by IDE ?

[chrome beacon]

Spigot should create it when you save the default config

[quaint mantle]

ah I use paper, maybe it's that

[chrome beacon]

Probably not

But hey if your code works that fine let's not over think this

[quaint mantle]

yea right

have a good day

[unreal quartz]

you don’t need to check if it exists

[silver wadi]

how do you create a default config?

[ivory sleet]

saveDefaultConfig() followed by
reloadConfig() iirc

[silver wadi]

oh

[ivory sleet]

Then you need a config.yml resource

[silver wadi]

So I can create that manually?

[ivory sleet]

https://www.spigotmc.org/wiki/creating-a-config-file/

[silver wadi]

Thanks

[ivory sleet]

Always check the wiki before asking here in the future

It contains a lot of substantial spigot concepts

[quaint mantle]

Guys I'm not sure what to input to retrieve the file onEnable

Map<UUID,Collection<Vector>> map2 = GSON.fromJson()

            File file = new File(getDataFolder(), "territories.json");
            FileWriter fw = new FileWriter(file);
            GSON.toJson(Territory.getAllTerritories().asMap(),fw);
        } catch (IOException e) {
            e.printStackTrace();
        }

this is where I built it on disable

[ivory sleet]

When reading you need a FileReader instead

[quaint mantle]

ah ok

so similar to above but with a reader

also

FileWriter fw = new FileWriter(file);

is "file" as input, correct here ?

it's hard for me to tell because the IDE doesnt refer the type that should be as inputs

[ivory sleet]

Multimap map = new Multimap()
FileReader reader = new FileReaded(new File(...));
map = GSON.fromJson(new TypeToken<Multimap<UUID,Location>>().getType(), reader);

[quaint mantle]

Hmm thanks ! so Gson will translate its own file directly into the Map, amazing!

[ivory sleet]

Yeah should work I think

[quaint mantle]

Hmm I get an IDE error "expression expected" before the Map<xxx>

[rocky glacier]

@quaint mantle
player.sendMessage(Message.getMessage(player.getUniqueId(), "prefix") + Message.getMessage(player.getUniqueId(), "message_ETC_price").replace("{amount}", money_formatter.format(API.ETC_price)));
}else if(args[0].equals("balance") || args[0].equals("bal") || args[0].equals("check") || args[0].equals("info")){

lol it made it spoiler bc of |

it would be args[0].equals("bal") with || at start and end

[silver robin]

https://wiki.vg/Server_List_Ping#Handshake
On this page it says an incoming server list ping contains data about the client's protocol version
How can i get this in a ServerListPingEvent?

[wraith rapids]

it probably isn't exposed by the spigot api

paper api might expose it

[silver robin]

yeah, there isn't a method to it
isn't it possible to get a handle to the actual packet object itself? (idc about nms)

[wraith rapids]

not from the event, I don't think

well, let me check

yeah no the bukkit event doesn't retain that information

and nms doesn't have an event bus that you could hook into easily afaik

consider using protocollib and listening to the incoming packet

[silver robin]

yes thats what i wanted

PaperServerListPingEvent has getClient().getProtocolVersion()
so guess i'll have to use protocol lib

[wraith rapids]

or paper :fingerguns:

[opal juniper]

Yeah you have to use the packets

Unless you use paper

[wraith rapids]

most people do

[opal juniper]

Ehh - I try and avoid developing against paper

But I run paper

[wraith rapids]

i build against paper exclusively because I want my things to actually be performant

but I usually add a fallback dependency for spigot

for those poor fucks who still run splögget

[opal juniper]

Lmao

Hi, can I make a spigot plugin from a gradle project? (I want to use firebase so I needed a built.gradle file and this seemed the easiest way to get one.)

[hexed hatch]

alright ill check it out tysm

[wraith rapids]

check your plugin.yml

[hushed lantern]

Pls help me

[wraith rapids]

yes, the build tool you use, if any, doesn't matter

you can use notepad and javac if you're gay enough

[regal moat]

can anyone recommend me a hosting? i want it to be good and cheap as possible. its for plugin development.

[eternal oxide]

Self host

can;t get cheaper

[swift nebula]

What do you recommend to learn how to create plugins?

[hexed hatch]

Learning Java

?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.

[regal moat]

my ram isnt enough

[rocky glacier]

pls help me with that

[quaint mantle]

Hey, is it possible to give a custom loot when someone gets a fish? like could I replace the fish with an item of my choice?

[eternal oxide]

If you don't have enough ram to host a home server you don't have enough to develop plugins

[regal moat]

i use 80% of my ram to develop plugins

and minecraft

[eternal oxide]

How much ram do you have?

[regal moat]

8 gb's.

[eternal oxide]

thats plenty

well, thats JUST enough

[granite stirrup]

i give 2gb to minecraft and 1gb to the server

XD

normally

[eternal oxide]

But you are going to have to be choosy over what you use. No Intelij, Only Eclipse

[regal moat]

i have just intellij and minecraft open, and i cant open the server with 2 gbs.

[eternal oxide]

Yeah, with 8 gig total you shoudl drop InteliJ

[granite stirrup]

the server doesnt need 2gb ....

if its just for testing

its fine with 1gb

[eternal oxide]

he needs OS, MC, IDE and Server

[regal moat]

in 1.12.2, yeah but 1.16.5 ... 🤷‍♂️

[granite stirrup]

intellij only uses like 1gb

max

[eternal oxide]

1.16 is ok for testing with 1 gig

[regal moat]

i always used 1.12.2 in the past

[granite stirrup]

u can run 1.16.5 with 1gb

its possible

but only for testing your plugins

and i ran a 1.17 server on 1gb just to test my shit

[eternal oxide]

Or you could save the money you would be spending on a host and instead buy more ram.

[regal moat]

its a laptop

[eternal oxide]

They do make laptop ram

[regal moat]

i use 4x2 ram

[eternal oxide]

they also make it in 8 gig sodimms

[regal moat]

and it only has 2 slots

wouldnt readyboost would be useful?

[eternal oxide]

not really

Hi, I created a build.gradle project, I copied the code from is link(https://www.spigotmc.org/wiki/spigot-gradle/) to the build gradle, I added some java also to test the plugin. BUT after I built the artifact and started the server, it thrown me error that says "cannot find a plugin yml". I have an plugin.yml file but I don't know where should I paste it where the program can find it

[compact haven]

I test my plugins on a vps kek

[granite stirrup]

you forgot plugin.yml in the resources

[rocky glacier]

that pops up when i launch server with plugin https://paste.md-5.net/nahayucegi.coffeescript

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

need some help here

[granite stirrup]

also dont just copy and use

[limber mica]

private String kitName;
    private ItemStack[] kitItem;
    private Enchantment enchantmentName;
    private int enchantmentLevel;
    private String requiredPermission;

    public KitManager(String kitName, ItemStack[] kitItem, Enchantment enchantmentName, int enchantmentLevel, String requiredPermission) {
        this.kitName = kitName;
        this.kitItem = kitItem;
        this.enchantmentName = enchantmentName;
        this.enchantmentLevel = enchantmentLevel;
        this.requiredPermission = requiredPermission;
    }

    public String getKitName() {
        return kitName;
    }

    public ItemStack[] getKitItem() {
        return kitItem;
    }

    public Enchantment getEnchantmentName() {
        return enchantmentName;
    }

    public int getEnchantmentLevel() {
        return enchantmentLevel;
    }

    public String getRequiredPermission() {
        return requiredPermission;
    }```
 right so I have
then make a class for each kit
have KitManager extended and have this 
```public t() {
        super(kitName, kitItem, enchantmentName, enchantmentLevel, requiredPermission);
    }```
but now I'm thinking about it and I don't know if this is actually gonna work how I want it to work. So any suggestions?

[granite stirrup]

actually read

[rocky glacier]

!!!!!!!!!!!!!!!!!!!!!!!!!!

[granite stirrup]

is kit manager abstract

[limber mica]

no

[granite stirrup]

you need it to be abstract if you want to extend it 🤣

[limber mica]

wait do you actually?

[granite stirrup]

yep

[hushed lantern]

When I use it in the resources folder it also says that "cannot find a plugin yml in the jar file"

[granite stirrup]

then your doing something wrong

idk

i dont use gradle

[maiden briar]

I try to center both, for the green line I expect the full line is 127 pixels (and start centering from behind with spaces). The blue line is line 1 of the motd and I also expect here 127 pixels and it starts with spaces at the front

[granite stirrup]

maven is better to me as in user friendly and more easier to use

[eternal oxide]

A class doesn't have to be asbstact to be extended, but you can;t instance abstract classes

[granite stirrup]

it doesnt?

i thought it does

[eternal oxide]

no

[maiden briar]

You can actually do new Class() {} even if abstract

[hushed lantern]

Can I use maven in IntelliJ?

[granite stirrup]

ye

fuck off

[dusk flicker]

@quaint mantle spammer

Few messages up

[maiden briar]

Exactly as the error sais, you have a null object

[rocky glacier]

yh if every1 ignores me

[granite stirrup]

doesnt mean you spam

[eternal oxide]

learn to read a stacktrace

[limber mica]

idkidk123123 now the reason I was thinking is that this won't work how I want it to is because there will be multiple items that will be in the kit

[dusk flicker]

You spamming us makes us just want us to fucking ignore you even more

[granite stirrup]

read the thing @rocky glacier ALSO show code

[quaint mantle]

who beat me

[dusk flicker]

Not sure

[quaint mantle]

😢

[granite stirrup]

but go to ur command class and change the return to true

next time read the stack trace and wait for help

[limber mica]

did ya read my response?

[granite stirrup]

¯_(ツ)_/¯

[eternal oxide]

If you are unable to read a stacktrace you can always post your link and ask how.

They are fairly simple once you understand it.

[granite stirrup]

i forgot how to fix this

how?

ive done it before but i forgot how

[eternal oxide]

which IDE?

how does paper solve plugins but spigot the plugins are broken on 1.17

[hybrid spoke]

wait how did you timemark this

[granite stirrup]

well not all plugins are broken on spigot

[hybrid spoke]

so manager is probably null

[regal moat]

how can i fix that?

[hybrid spoke]

do you have protocollib as a soft dependency?

[dusk flicker]

assert manager != null; /s

[regal moat]

well i have it on my pom.xml and i have no clue what you are talking about

i also have it in my plugins folder

[hybrid spoke]

you can add plugins which your plugin depends on to your plugin.yml so your plugin will just be loaded if the dependency is loaded

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

[regal moat]

softdepend:
  - ProtocolLib
```like this?

[hybrid spoke]

most likely

also, ```

this

[sage swift]

so lets think

what does this mean

[regal moat]

maybe since i already have protocollib inside of my plugin?

[sage swift]

no

[regal moat]

hm

[sage swift]

Caused by: java.lang.IllegalArgumentException: Plugin already initialized!

[regal moat]

hm

[sage swift]

what does this mean

[regal moat]

i have one clue

my plugin initalized it first and spigot tried to initialize it again

[sage swift]

other way around

[regal moat]

Oh?

[sage swift]

since you have it as a softdepend

you dont need to initialize it since it's already initialized

[regal moat]

when i got this error

i didnt

i didnt test it with the softdepend in the plugin.yml

[sage swift]

you initialize it somewhere in your code.

[hybrid spoke]

probably in the spawnbee or listenerbee constructor

[regal moat]

spawnbee is a command

it has nothing to do with it

[sage swift]

although i guess in the error above since it's not a softdepend you initialized it first

[regal moat]

so i should add it as a softdepend and try

[sage swift]

you should not initialize it in your code

[hybrid spoke]

what is powder

[regal moat]

its the name of the plugin

[hybrid spoke]

org.powder.Main.<init>(Main.java:16)

[regal moat]

i just typed random shit

[sage swift]

but yes, add it as a softdepend and it will show you the error line

from your end

[regal moat]

16 is ```java
public final class Main extends JavaPlugin {

[hybrid spoke]

so you are somewhere creating a new instance of your own plugin ig

[sage swift]

no

what are you on about

his code is initializing ProtocolLib

[regal moat]

what should i do to fix it then??

[granite stirrup]

wait is this a bug or this intonational when you make a static method in intellij it says its being used when it isnt?

[regal moat]

ok added it as a softdepend

now trying

[quaint mantle]

Used/unused checks for intellij is definitely far from good in my experience

[regal moat]

okay no errors

[eternal night]

I think there was a config option to consider static methods entry points by default

[ivory sleet]

What’s bad about it

[granite stirrup]

falses

[regal moat]

it works lol

[opal juniper]

EventListeners always appear in unused

[eternal night]

Makes sense ?

[ivory sleet]

Yeah it can only predict compile time shit obv

[eternal night]

They are invoked using reflection lol

[upper mica]

Hello, so I need to log information into file, and I will also use it as for 'history' command, what file type should I choose? I was thinking yaml, because its easier to read and write values, but it's more like for configuration stuff

[eternal night]

How is intellij gonna now

[opal juniper]

Magic 🪄

[eternal night]

:5head:

[opal juniper]

For just logging you can use a text file

[granite stirrup]

actually probs not in 1.17

[regal moat]

so i am trying to make the bee rideable

?paste

[undone axle]

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

[granite stirrup]

cuz reflection doesnt work in java 16

[regal moat]

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

the controls work

but the rotation doesnt

for some reason

[eternal night]

Omg why is everyone saying reflection doesn't work in java 16

[opal juniper]

It works, but differently…

[eternal night]

Like, read

It works perfectly fine

[granite stirrup]

it doesnt work?

[eternal night]

Unless the code access is encapsulated by a module

And your plugin isn't

Neither is the server internals

[opal juniper]

I mean I avoid it so idrk but I have heard that you have to change stuff so that was the basis of this ^^

[eternal night]

Or craftbukkit, spigot or paper code

[regal moat]

no errors

help please

[granite stirrup]

can anyone tell me why maven thinks this is bad str.replaceAll("([a-z0-9])([A-Z])", "$1-$2").toLowerCase(); it says uses unchecked or unsafe operations.

im using it to convert camel to kabab

[opal juniper]

Dafuq is kebab lmao

Never heard of it

yeah but why does it say that it uses unchecked or unsafe operation.

[eternal night]

wild, my intellij says nothing when trying to call this method

[opal juniper]

He said his maven

But idk

[granite stirrup]

it doesnt say anything about it but when i do mvn package

it says something

[regal moat]

https://paste.md-5.net/maregozuxi.java
the controls work
but the rotation doesnt
for some reason

[granite stirrup]

@eternal night should i just ignore it i mean its just a warning

it doesnt stop it from building

[eternal night]

What maven version are you using

I cannot reproduce this

[granite stirrup]

idk

[eternal night]

what is the maven warning

[granite stirrup]

[WARNING] /C:/idk/src/main/java/test/idk/idk/Main.java: Recompile with -Xlint:unchecked for details.```

[eternal night]

and you are 100% sure this is caused by the specific line ?

[granite stirrup]

yep

because after i added

this happend

i have Apache Maven 3.6.3

[eternal night]

try to update maven to latest ¯_(ツ)_/¯

update compiler as well

[granite stirrup]

i dont really want to update maven

[eternal oxide]

This is not giving you an unchecked warning

[granite stirrup]

it is

cuz after i added it

[eternal night]

can you recompile using -Xlint:unchecked

[granite stirrup]

it says this

[eternal night]

so you can compile with exactly this one line removed

and the warning is gone ?

[regal moat]

https://paste.md-5.net/maregozuxi.java
the controls work
but the rotation doesnt
for some reason

[granite stirrup]

uh when i did before it did but now it doesnt

[eternal night]

🤔

[eternal oxide]

That line is a simple regex replace, it doesn't cast anything

Nothing unsafe about it

[granite stirrup]

oh f i think i figured it out

i cast some other class somewhere to a T which is passed in through the class using these <T>

but it wasnt causing a warning before

so idk why it is now?

[burnt current]

Hey quick question: Is it possible to query the display name of an item not whether it has a certain full name, but only whether a certain word occurs in the item?

[eternal night]

I mean, there is just String#contains

[quasi flint]

Which works

[burnt current]

ok and what would be the best way to include this in event.getCurrentItem().getItemMeta().getDisplayName()?

[eternal night]

a) you are missing a bunch of null checks there
b) getDisplayName().contains("my substring")

[quasi flint]

Store that in an variable?

[quasi flint]

For further use

But i dont know If U need that

If Not use Lynx's answer

[burnt current]

This is not the full code of this paragraph. It is the following:

if(event.getCurrentItem().hasItemMeta()) {
                            switch(event.getCurrentItem().getItemMeta().getDisplayName()) { 

[eternal night]

a switch statement is not an if and does not allow partial checks

switch doesn't work like that

[burnt current]

I don't think I need it. But thanks for the tip

[eternal night]

switch is just a pretty form to express a lookup table in code

[sage swift]

but dont use display name for custom items

pls

holy shit

or guis

[burnt current]

I already thought so

[quasi flint]

Tf u want to achieve with thay

[quiet ice]

switch on strings works with hashcodes for anyone interested

[burnt current]

What is more suitable for this?

[sage swift]

Doesn't it also just works with normal strings ? why use hashcodes. afaik java 7 introduced string switches

i need to move the vehicle

with rotation

it rotates fine

but it doesnt move in the rotated direction

[burnt current]

ok thank you

[eternal night]

this is not how steer packet works

https://wiki.vg/Protocol

read up on what the values represent

[quasi flint]

Never worked with persistent data holders

Pretty smort things

[regal moat]

i know

i am just new to spigot

[eternal night]

then why are you passing these values as x and z velocity values into the velocity

if you know xD

[quasi flint]

Well dis not gonna work

[eternal night]

just, be vary on storing a) half a database on them and b) 100% do store the item meta you are reading them off. getItemMeta is a very very expensive call.

[compact haven]

wot

[quasi flint]

10€ a call

[compact haven]

I never heard that getItemMeta is expensive?

[eternal oxide]

it copies

[eternal night]

the entire thing

also parses it all

[regal moat]

i know that i should read it 🤦‍♂️

[quasi flint]

I personally store my coins not on my mysql. I store em on my items lol

[eternal night]

:5head:

[compact haven]

how is persistent item data stored

I assume its just an abstraction for nbt

[eternal night]

then maybe do that next time before asking, if you knew it already 😉

it is

[quasi flint]

When u take wallets to seriously in minecraft

[compact haven]

like it could be implemented in any version, not just 1.14

[eternal night]

internally it uses NBT yea

just do not think of it as a NBT API

[compact haven]

mmm?

[eternal night]

the API very specifically does not allow generic nbt modification

[compact haven]

right

[eternal night]

e.g. you couldn't modify the items display name with it

[granite stirrup]

any better way than what i have done XD java public static String kababToCamel(String str) { String result = ""; String[] strings = str.split(""); for (int i = 0; i < str.length(); i++) { if (strings[i].equals("-")) { result = result + strings[i + 1].toUpperCase(); continue; } else if (i == 0) {} else if (strings[i - 1].equals("-")) { continue; } result = result + strings[i].toLowerCase(); } return result; }

[eternal night]

use a StringBuilder

[regal moat]

my small brain cells cant understand it.

[granite stirrup]

idk how to use that

[eternal night]

the values in the packet only represent if the player pressed the forward,backwards or left and right buttons

not actually the rotation

you will need to calculate the vector from it

[quasi flint]

smooth

[sage swift]

java.lang.NullPointerException: Cannot invoke "org.bukkit.World.getBlockAt(org.bukkit.Location)" because the return value of "org.bukkit.Location.getWorld()" is null
getting this on startup despite having load: POSTWORLD because it's loading before the worlds for some reason... any ideas for a fix other than delaying it by a tick?

[eternal night]

Seems more like a question as to where your location comes from

[sage swift]

well not really

the World is null

[quasi flint]

I think getting world before the world is there is bad

Or am I smooth brain

[eternal night]

Yes, the locations world. I can create a location at runtime that doesn't have a world assigned to it

[sage swift]

the location includes the world.

it's just that the plugin enables before the worlds

oh

it might be that i need softdepend on multiverse

one sec

[regal moat]

i still do not understand, i dont think i will either

[eternal night]

then maybe look for existing plugins to do what you are trying

[sage swift]

yep, it was because the plugin was enabling before multiverse loaded custom worlds

thanks for all your help guys 😉

[quasi flint]

Even though we did nothing yeah sure 😂

[sage swift]

exactly

[eternal night]

mental support

smh

that counts for something

[quasi flint]

From a mentally unstable person

[granite stirrup]

isnt looping slow?

[quasi flint]

Seems reasonable

[granite stirrup]

    public static String kababToCamel(String str) {
        String result = "";
        String[] strings = str.split("");
        for (int i = 0; i < str.length(); i++) {
            if (strings[i].equals("-")) {
                result = result + strings[i + 1].toUpperCase();
                continue;
            } else if (i == 0) {} else if (strings[i - 1].equals("-")) {
                continue;
            }
            result = result + strings[i].toLowerCase();
        }
        return result;
    }``` can someone help me revamp this XD

[quasi flint]

Stringbuilder says henlo

[granite stirrup]

thing is idk how to use that

[sage swift]

why not split via "-"

[eternal night]

^^ could just uppercase each array start

[sage swift]

if youre trying to get the characters why not use toCharArray

[granite stirrup]

i wanna make sure i get all the characters correctly uppercased and lowercased

[sage swift]

word.substring(0, 1).toUpperCase() + word.substring(1).toLowerCase()

[quasi flint]

?paste

[undone axle]

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

[quasi flint]

Some code I found online

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

[eternal night]

the fuck

is that formatting

[granite stirrup]

@quasi flint thats snake to camel

and not kabab to camel

[eternal night]

snake and kabal just different delimiters no ?

one uses _ the other -

[quasi flint]

Tf is kabab

Brain smooth

[granite stirrup]

kabab-case

[turbid wind]

Minecraft commands naturally suggest stuff like "[<level>] above the message when there's no tab complete and all. How can I do the same?

[sage swift]

https://github.com/Mojang/brigadier

[quasi flint]

The same shit just with -

So replace my _ with -

And workes I guess

[eternal night]

https://paste.md-5.net/ulasuwuvac.java this might also work

no guarantees tho

Pattern.compile("[-_](\\w)").matcher(input).replaceAll((r) -> r.group(1).toUpperCase());

[lunar wedge]

How do I get UUID of an offline player by just their Name?

[wraith rapids]

call getOfflinePlayer with the name

note that it can and probably will make a blocking network request to mojang

so you don't want to do it synchronously on the main thread

i don't know how to put it any clearer

[granite stirrup]

isnt that deprecated ?

[wraith rapids]

call getOfflinePlayer

pass the name as an argument to it

it is deprecated but it is still a perfectly valid operation, not subject to removal, and fine to use

read the deprecation note

[hybrid spoke]

its just deprecated cause it sends the request to mojang

[granite stirrup]

lol

[regal moat]

i still have no idea how

[wraith rapids]

bukkit deprecations aren't real deprecations

[hybrid spoke]

not sure if iterating over the offline players would make more sense

or if getOfflinePlayer already checks them

[wraith rapids]

it does

[hybrid spoke]

ah good

[wraith rapids]

it uses the local usercache if the name is cached

in fact paper has a specific overload or a variant that does not make the network request

and only checks the usercache

[regal moat]

gosh just help me

[wraith rapids]

what even is your issue

and no, I can't see replies

you'll have to put some actual effort into it and cuntpaste the thing instead of .'ing it

it rotates fine
but it doesnt move in the rotated direction

[granite stirrup]

why?

[hybrid spoke]

~ Core

[wraith rapids]

what is that supposed to mean

[lunar wedge]

Thanks! I got it to work

[wraith rapids]

how do you move something with rotation

do you mean relative to its rotation

[eternal night]

and he doesn#t understand that the packet does not send the actual rotation but rather boolean style int flags what keys were pressd

[granite stirrup]

nn why cant u see replys?

[hybrid spoke]

i am not sure how you can rotate something without rotating

wait

what version is it

[regal moat]

1.16.5

[wraith rapids]

probably 1.8

[regal moat]

its a bee damn it

[wraith rapids]

were boats even in the game in 1.8

[hybrid spoke]

the entities looks like they've been rotated

but they doesn't

[eternal night]

NNY is obviously famous for living the life of ripcord

[regal moat]

...maybe?

[hybrid spoke]

if you spec them in spec mode you can see that they still are looking into the direction like before

[wraith rapids]

vehicles are pretty buggy with rotation

well, boats are

[granite stirrup]

whats ripcord

[regal moat]

so, what do i have to do here?

i have no idea

[wraith rapids]

dunno bout minecarts

[hybrid spoke]

couldn't find a fix yet but probably didn't looked deep enough into it

[wraith rapids]

give up i suppose

No

you have to kill the drops

[quasi flint]

Tf Electrons related to Germans?

[granite stirrup]

:)

[steep nova]

wait

[granite stirrup]

what lynx said

[wraith rapids]

electron isn't related to germany, I wouldn't think

[steep nova]

nvm

[wraith rapids]

it is closely related to shit, though

[quasi flint]

That's what I think as a German lol

[quasi flint]

Well nuclear bomb I guess

[wraith rapids]

that is anti german

[quasi flint]

But the Americans did it so more related to em

[granite stirrup]

apparently this works java StringBuilder s = new StringBuilder(); char[] chars = str.toCharArray(); for (int i = 0; i < chars.length; i++) { if (chars[i]=='-') { s.append(("" + chars[i + 1]).toUpperCase()); continue; } if (!(i==0) && ("" + chars[i - 1]).equals("-")) { continue; } s.append(("" + chars[i]).toLowerCase()); } return s.toString();

[hybrid spoke]

you could probably deep search it. already tried the nms and normal way. good luck. @ me if you found smth

[wraith rapids]

built by the amerimutts and conceptualized by a jew

[quasi flint]

Well then good

[wraith rapids]

about as not german as you can get

[quasi flint]

Good it wasn't dropped here ;7

[quaint mantle]

how i can get CustomModelData from armorstand's ArmorItems in spawner?

[granite stirrup]

:)

[wraith rapids]

is this your first plugin

[proud basin]

if I'm correct this should give a speed potion

ItemStack potion = new ItemStack(Material.POTION, 1);
PotionMeta potionmeta = (PotionMeta) potion.getItemMeta();
potionmeta.setMainEffect(PotionEffectType.SPEED);
potion.setItemMeta(potionmeta);
p.getInventory().addItem(potion);

[granite stirrup]

me or someone else?

[wraith rapids]

maybe, dunno; potion meta and shit has been changed since 1.8

i don't know how the new system works, and I don't remember how the old system worked

[granite stirrup]

i thought you use the PotionCreator for potions

PotionBrewer

i mean

[wraith rapids]

neverheard

[granite stirrup]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/potion/PotionBrewer.html

it a interface tho so it might not be how you do it

lol it got deprecated cuz it doesnt work XD

[earnest sonnet]

I guess you play with getDrops()

[wraith rapids]

also for the snake to camel conversion, on java 1.9 this should work
Pattern.compile("[-_](\\w)").matcher(input).replaceAll((r) -> r.group(1).toUpperCase());

will convert it to lower camelcase

[granite stirrup]

uh

[wraith rapids]

Pattern.compile("([-_]|^)(\\w)").matcher(input).replaceAll((r) -> r.group(1).toUpperCase());
will convert to upper camelcase

[granite stirrup]

that way might be better than what i have done it but im gonna stick to the way i have currently

[eternal night]

just please cache the compiled pattern

[wraith rapids]

of course you don't want to compile the pattern every time

[eternal night]

yes

[wraith rapids]

but that is for the sake of brevity

[granite stirrup]

yeah i dont understand regex so ima stick to loops and stuff XD

even if its bad idrc

[earnest sonnet]

newbie mistake, done that a few times while learning and I had a headache

[ivory sleet]

Doesn’t it get optimized?

[wraith rapids]

i doubt there is any internal caching going on in there

[eternal night]

I don't think JIT would actually cache yea

[ivory sleet]

Hmm fair then

[regal moat]

mmm

[wraith rapids]

not sure if the compiler does anything about it

[regal moat]

maybe i found it

PacketPlayOutEntityHeadRotation?

[wraith rapids]

JIT might do something about it

[granite stirrup]

what if the string changes and you want to do it like every time you ran a command?

[wraith rapids]

the string doesn't change, if you mean the regex string

[eternal night]

no way JIT caches instances of pattern

[wraith rapids]

if you mean the input string, you call pattern.matcher(input)

where pattern is the precompiled pattern

and input is your input

[granite stirrup]

oh

[novel mauve]

Help

[granite stirrup]

yeah i dont understand regex so i might just use for loops and stuff

[wraith rapids]

can't see embed txts

[eternal night]

you are running outdated java

[novel mauve]

I cant figure out what to do in the ide

yeah i know im not using hte right version but i dont know which one to use

[wraith rapids]

it probably says that

[eternal night]

you compiled with java 15

and run with java 10

so, just run with java 15

[granite stirrup]

LOL

[novel mauve]

Ohh okay

[granite stirrup]

or java 16

[eternal night]

or better, upgrade both to java 16

yea

[novel mauve]

Thanks

[granite stirrup]

java 16 is evil tho

[eternal night]

it. really isn't

[granite stirrup]

to me it is

[eternal night]

Are you modifying static final fields using reflection ?

[wraith rapids]

anything past 8 is

[main dew]

what is this CraftComplexRecipe and CraftSmithingRecipe?

[wraith rapids]

a complex recipe and a smithing recipe, respectively

[eternal night]

I'll start a list of people that like java 8

[wraith rapids]

the concrete classes part of the craftbukkit server implementation that each implement the corresponding bukkit api classes

java 1.8

how fitting

[proud basin]

how come huh

[granite stirrup]

not really but in java 16 i would like to have it ;-;

and you cant do that in java 16

[main dew]

anvil? yes?

[wraith rapids]

no the smithing bench thing i think

whatever it's called

i don't think anvils use recipes

[eternal night]

if you ever run into that issue, be a useful person and PR a change.

[granite stirrup]

idk some people say that mojang made packets have final fields and they need them to not be final so they can make packet listeners idk

[wraith rapids]

your mom

[granite stirrup]

?

[hybrid spoke]

reflections are bad

and should nearly never be used

[granite stirrup]

but you need it for some things

[hybrid spoke]

not really

[granite stirrup]

packets?

nms

[hybrid spoke]

reflections are a bad usage except your are doing your own framework

[granite stirrup]

¯_(ツ)_/¯

[ivory sleet]

Yeah kinda agree with luzifer, shouldn’t be used unless you have a decently justified reason for it

[regal moat]

its just fucking facin south. i am having the same problem as https://www.spigotmc.org/threads/set-body-rotation-of-a-livingentity.46377/

potionmeta.addCustomEffect(new PotionEffect(PotionEffectType.SPEED, 3600, 0), true);
potion.setItemMeta(potionmeta);
p.getInventory().addItem(potion);

So now im just wondering should I just get console to give them it

nope
