so this is a error that is spammed in my console every time i try to connect to the server via bungeecord

its 1.8.8 server in bukkit.yml the connection throttel thing is at -1 in spigot.yml bungecord is set to true and in server.properties online mode is set to false and in the proxi its the the second in priority and ip forwarding is true and its on the correct port

its the first 1.8.8 server im releasing on to my network and for some reason this is giving me a issue however all the over servers on the network work just fine

[quaint mantle]

Hey, so i again have an little problem.
(cant copy the code with correct indent, that why i send an image link)

https://imgur.com/a/ceFyWhS

it works but it gives out the whole log file and spams the whole chat.
what i want:
only the latest line of the log.

how would i do this?

[formal bear]

add continue for not last line?

[quaint mantle]

yea but how do i get the last line? how should java/the code know what the latest line is?

[gleaming olive]

How can I calculate damage ?
player.damage() just damages the player without checking for armor points and enchantments... in 1.8

damagemodifer armor then substract it from damage value?

I am on 1.8

[wintry badger]

hi, hasPermission method returns always true if the player is OP. is there any workaround for it? or do i have to get a full list of the perms and then check for the specific perms?

default: false in plugin.yml will work?

but what if the plugin contains an integer?

keepinventory.partially.30 for example

[summer scroll]

OP will have every permission.

[summer scroll]

Maybe try to use Player#getEffectivePermissions, and loop through that.

[rare flicker]

other crappy but probably functional way that everybody will hate :

• check if he's OP
• if so Deop
• check perm
• if was opped, reop

[summer scroll]

yikes

[rare flicker]

i mean, it works, its really not how its meant to be used

but it SHOULD work

[summer scroll]

The better solution is to organize your groups on the permission plugin and avoid use op

[rare flicker]

^^^^

Unrelated :

What would be the best way to store an itemstack as text format. I've looked a bit into serialization but i'm not sure if there's an API way of doing it or if you have to use serialization

Given i need to store EVERYTHING, so, NBT data, lore, tags like HIDE_ENCHANTMENTS, durability etc

[summer scroll]

Maybe base64?

[tardy delta]

ItemStack#serialize?

is that a thing?

[rare flicker]

i think it is, i'm just not too sure if its the best way

[summer scroll]

ItemStack is configuration serializable yes

[rare flicker]

then i just loop through every element in the hashmap and store it in text format?

[wind sphinx]

Check if a player can build in a specific location

[formal bear]

How to add element to List?

List<Material> test = new ArrayList<>();
test.add(Material.GRASS_BLOCK);

Code above does not work

[harsh totem]

If I have a file named "data.json" in a plugin's resource folder, would it's path be just "data.json"?

[tardy delta]

new File(plugin.getDataFolder(), "data.json")

or new File(plugin.getDataFolder() + File.separator + "data.json")

[harsh totem]

ok i'kk try

i'll*

[wind sphinx]

It should work... maybe new ArrayList<Material>(); instead of new ArrayList<>();

[harsh totem]

@tardy delta thank you!

[formal bear]

😵‍💫

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[tardy delta]

ofc it doesnt work, there is no add method which takes 0 params

[formal bear]

it does not work with test.add(Material.GRASS_BLOCK) either

[warm saddle]

How would I get the block that a player has walked on from a PlayerMoveEvent?

like the block type?

[tardy delta]

get the block under the location of the players feet

player.getLocation().getRelative(BlockFace.DOWN) or smth

[pastel juniper]

I created a claim system, but when I want do to disable pvp for all player except the chunk owner and op, it doesn't work

            if(ClaimSystem.isChunk(chunk)) {
                UUID uuid = player.getUniqueId();
                if (ClaimSystem.getBD(chunk) == true) {
                    if (!(ClaimSystem.getOwner(chunk, uuid).equals(player.getUniqueId()))) {
                        if (!(player.isOp())) {

[harsh totem]

why does it get this error? Caused by: java.lang.ClassCastException: class java.lang.Long cannot be cast to class java.lang.Integer (java.lang.Long and java.lang.Integer are in module java.base of loader 'bootstrap')

the value that's supposed to be returned is integer and it is in the json file

[tardy delta]

cast it to a long and then to an int idk lol

[ivory sleet]

cast to Long and use intValue

Or the opposite

Integer -> longValue etc

[rare flicker]

what is this devilish creature

[rare flicker]

i found the solution, and it is waaaaaaaaaaaaaaaaayyyyyy easier than what i was looking into

YamlConfiguration has a .getItemstack(String) method, and you can also .set(Itemstack). Just let it handle everything

[west crag]

hey can anyone tell me which method will be good to increase difficulty of game?

If someone use this command /easymode then less mob should spawn and all code for this function will go to this method :- ```java
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
if(command.getName().equalsIgnoreCase("easymode")) {

        if (sender instanceof Player) {
            - - - code - - -
        }
    }

or should i make new class or new method for this? and then call it from this method?

[tardy delta]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#setDifficulty(org.bukkit.Difficulty)

[west crag]

no

that was an example just

its going to be something else

[west crag]

btw thanks for this i will use this somewhere :)

[tardy delta]

¯_(ツ)_/¯

[west crag]

:)

no really it will help me :)

i will use this in mob spawning stuff

[sinful rapids]

player.getInventory().addItem(a);

not work, i use java11 and server spigot 1.12.2. gives me player in red

idk if this is the right channel for that, but am I allowed to Upload Paper Plugins to Spigotmc.org?

[west crag]

yes

wait

[manic crown]

okay, thank you

[drowsy helm]

if it doesnt use paper only api, yes

[manic crown]

and where do I upload it if there are paper only things?
without github...

[tardy delta]

paper site

[drowsy helm]

i think paper has hangar

[manic crown]

okay...

[quiet ice]

hangar isn't really a thing yet however

[drowsy helm]

you can just make a spigot port

[quiet ice]

I think you can also just upload them to bukkitdev, they do not care about the difference anymoree

[ivory sleet]

if and only if it can run on spigot as well

[harsh totem]

how do I check if a raid was finished because the players won and not because the player's lost with RaidFinishEvent?

because RaidStopEvent isn't executed when the raid is won

[main dew]

How I can disable create end portal like this?

[tardy delta]

check the result

and before complaining that you dont know what those enum constants mean check the docs

[harsh totem]

there is no result in raidFinish.
i tried to use result in raidStop but the entire event is only executed when the players lose for any reason

[harsh totem]

i have

[tardy delta]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/raid/RaidFinishEvent.html
?

[harsh totem]

i tried to use result in raidStop but the entire event is only executed when the players lose for any reason

[harsh totem]

i know what is says i just read it

i checked and it isn't executed when it's won

i did the same check one time winning and one time losing and nothing happened when i won

[tardy delta]

it should lol, did you register it?

[harsh totem]

yes

[harsh totem]

.

[eternal oxide]

Have you also checked the Raid Stop Event?

[harsh totem]

I have this @EventHandler public void Hero(RaidStopEvent event) { Player ytg667 = Bukkit.getPlayer("YTG667"); ytg667.sendMessage(event.getRaid().getLocation().toString());
when i win nothing is printed. when i lose it's printed

[tardy delta]

method names should start with a lowercase character.. again...

[harsh totem]

why does it matter

[tardy delta]

because conventions

[glass mauve]

you also hardcoded the player

[eternal oxide]

Makes it easier for everyone else to read your code

[tardy delta]

it would throw anyways otherwise

[eternal oxide]

a Capital letter indicates that is a Class not a method

[harsh totem]

i only did it to print to the player

its for debugging

[glass mauve]

isnt there no event.getPlayers or smth like that?

let me look in the docs

[eternal oxide]

I would assume RaidFinishEvent would fire fora win only

RaidStopEvent seems like it would fire if the raid was lost

[tardy delta]

dunno what clear result means

[eternal oxide]

actually RaidStopEvent would fire always

[harsh totem]

the docs say that it executed whenever a raid id done whether is was won or lost

[glass mauve]

RaidEvent got a getRaid() method. Raid got getHeroes method which returns Set<UUID>

[quasi patrol]

It is only triggering for command argument tab completing, not the actual command itself tab completion.

[glass mauve]

there is a Raid.RaidStatus enum with LOSS, ONGOING, STOPPED, VICTORY

both RaidStopEvent and RaidFinishEvent inherit from RaidEvent

[eternal oxide]

TabCompleteEvent is only for args on commands

[glass mauve]

RaidFinishEvent is for VICTORY

cause there is a getWinners() method which returns a List of Player

[harsh totem]

oh ok thx

[quasi patrol]

Unless it is console?

[eternal oxide]

Command TabComplete is done from the CommandMap

Note that due to client changes, if the sender is a Player, this event will only begin to fire once command arguments are specified, not commands themselves. Plugins wishing to remove commands from tab completion are advised to ensure the client does not have permission for the relevant commands, or use PlayerCommandSendEvent.```

[tardy delta]

just dont give them permission to execute the command

¯_(ツ)_/¯

[eternal oxide]

Yep, no permission it won;t be in their command list

[sterile cloak]

Hello, anyone can help mi with that? I want to change every link sended by player in chat change to my link, i know, i need to to that with AsyncPlayerChatEvent and regex but i don't have idea how (and i mean replacing by converting url to another based on url so example: String originalurl = ""; byte[] enc = originalurl.getBytes(); String encoded = Base64.getEncoder().encodeToString(enc); String replacedurl = "https://nonexist.nonexist/something.php?=" + encoded + "";

[eternal oxide]

https://stackoverflow.com/questions/30143037/finding-and-replacing-an-url-using-regex-in-java

[sterile cloak]

i already founded exactly that and didn't helped me

[eternal oxide]

It literally gives you the regex to find ANY url and replace it

[sterile cloak]

but it must replace exactly from original url

converted

[eternal oxide]

what?

you have an incoming String in teh getMessage(). Perform replaceAll with that regex

[sterile cloak]

yes but how exactly replace every url with new converted url?

you readed my example to convert?

[eternal oxide]

String regex = "(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|]";

//in Event

event.setMessage(event.getMessage().replaceAll(regex, "http://yoururl.com"));```

[sterile cloak]

i know about that

problem is detection original url

because that must be converted

[eternal oxide]

what must be converted? The getMessage() should be in plain text

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

[sterile cloak]

for understanfing: player in chat send message with example: https://www.youtube.com and i need that url replaced by my url but original player url must be converted to base64

[eternal oxide]

why muist it be converted?

[sterile cloak]

url that player sended

[eternal oxide]

if you want to encode then encode it Base64.encode

why?

[sterile cloak]

because of web api

[eternal oxide]

I don;t understand what Base64 encoding has to do with anything

[mortal hare]

Its easier to send data in Base64 than in binary form

[eternal oxide]

ok, lets start over. You asked how to replace all player entered web links with yours.

[sterile cloak]

yes but every that link must be separatelly converted

[eternal oxide]

why?

[sterile cloak]

because of web api

[eternal oxide]

web api has nothign to do with player chat

[sterile cloak]

yes, it has, because of ad link

[eternal oxide]

I'd suggest you go reformat your question as you are only giving broken pieces of it.

[sterile cloak]

my english isn't perfect, that is true

[eternal oxide]

web api and ad link are nothing to do with your original question

[sterile cloak]

so converted chat link -> my web -> linkvertise -> final target link

[eternal oxide]

Are you wanting to do something with the web links that the player has entered?

[sterile cloak]

that's the point, replacing original links

[eternal oxide]

Then compile a Pattern from the regex and you can process each match

[sterile cloak]

i know, i need to do that but I'm really bad in regex

[eternal oxide]

search regex pattern matching

you already have the regex

[sterile cloak]

yes

[eternal oxide]

you literally create a Pattern from it

then loop any matches

[sterile cloak]

and that's the problem, how?

how to exactly do that specific operation i want

[eternal oxide]

https://www.tutorialspoint.com/java/java_regular_expressions.htm Scroll down to the section that has while(m.find())

[sterile cloak]

i don't understand that regex, I'm literally self-learned but regex is not my part ....i tried exactly use that ..... don't worked

[eternal oxide]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[ivory sleet]

yes regex is well... interesting to say the very least

[ivory sleet]

anyway you probably wanna cache the regex

since that'd compile it every time you invoke it

[sterile cloak]

I'm tried to that and don't worked ... I'm literally don't understand regex

oh... i can't send image

[subtle folio]

i didnt know you could make projectiles bounce lmfao

[ivory sleet]

verify

[sterile cloak]

i literally don't have idea, how to do that i want

[tardy delta]

store the pattern as a field

regex slow

[ivory sleet]

ye if you have to compile it every time

[eternal oxide]

Not tested, but somethign like ```java
Pattern patern = Pattern.compile("(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~|!:,.;]*[-a-zA-Z0-9+&@#/%=~|]");

public void findURL(String message) {
    
    Matcher match = patern.matcher(message);
    
    int count = 0;
    
    while (match.find()) {
        System.out.println("Found: " + match.group(count));
        count++;
    }
}```

[tardy delta]

why getting the bytes of a stringbuffer.toString?

dont even know what a stringbuffer is lol

[quiet ice]

Don't use StringBuffers

StringBuilders are almost always more appropriate

[ivory sleet]

^they're badly optimized due to "antique" thread safety

[quiet ice]

But in this case the allocation is superfluous as you'd really want to call String#getBytes

[hybrid spoke]

you dont have to. if you've made nothing wrong you'll never need it

[quiet ice]

StringBuilders on the other hand are the best shit out there

[hybrid spoke]

hah, y'all need a builder to make a string?

i just do ""

[formal bear]

where i can find list of minecraft sounds with preview

[hybrid spoke]

?bing

[undone axle]

Bing your question before asking it:
https://www.bing.com/

[quiet ice]

That used to internally create a StringBuilder

[ivory sleet]

yeah well basically StringBuffer with no obsolete synchronization

[quiet ice]

JIT probably optimises a fair bit there, but using a shared StringBuilder instance is rather neat

[quiet ice]

heh

Is it possible to set a Entity's bounding box?

so like they can only walk inside that area?

[quiet ice]

That is a very strange definition of bounding box

[subtle folio]

lmfao Im not exactly sure how to even use it so

[quiet ice]

Or at least not the traditional connection

[hybrid spoke]

well

[quiet ice]

It is the right term, yes

[hybrid spoke]

what are you trying to do

[eternal oxide]

call it a region (BoundingBox) 🙂

[subtle folio]

Im trying to allow mobs to only walk within a certain area of their spawn

[hybrid spoke]

ohh i thought of a hitbox

[crimson terrace]

Ive done that recently. I set a bounding box and check whether that bounding box contains the entities bounding box, if not i tp them back inside

[quiet ice]

And this is why I said that

[subtle folio]

What event would I even call that in?

[crimson terrace]

I made my own

[pastel juniper]

I disabled door opening with this :

block.getState().getData() instanceof Openable

But still can open Crimson and Warped doors

[crimson terrace]

every second I go through the entities Ive assigned a bounding box to and check

[subtle folio]

every second 😳

[crimson terrace]

yes

not every tick

[subtle folio]

wouldn'

[quiet ice]

You can spread out the workload across multiple ticks anyways

[subtle folio]

yeah

[tardy delta]

i liked this post https://www.spigotmc.org/threads/guide-on-workload-distribution-or-how-to-handle-heavy-splittable-tasks.409003/

[crimson terrace]

you could yeah. for my purposes its not necessary tho. at least not for the targetted servers

[subtle folio]

hmm okay

that bounding box contains the entities bounding box
Could you explain this to me? @crimson terrace

[crimson terrace]

BoundingBox#contains(BoundingBox boundingBox)

[subtle folio]

Uhuh

[crimson terrace]

any problem?

[subtle folio]

How do I set a zombie's bounding box?

[crimson terrace]

a boundingbox is a hitbox basically

you dont set them

[subtle folio]

OHHH

[crimson terrace]

you have to make another bounding box and check whether the zombies box is inside the big one

[subtle folio]

So I should make a bounding box that get init'd onenable for their allowed locations

[crimson terrace]

give me a stone axe don't axe iron, how can I solve?

[tardy delta]

doesnt make sense

[eternal oxide]

It would probably be cheaper to just set a tether range

[tardy delta]

have you restarted your server with the new plugin?

[sinful rapids]

yes

[subtle folio]

https://www.javatpoint.com/java-naming-conventions

[crimson terrace]

the code you sent gives you an iron axe, the problem must lie somewhere else

[crimson terrace]

did you have it as a stone axe before?

[sinful rapids]

nope

always iron

[crimson terrace]

then you have different code which gives you a stone axe

you on intelliJ?

[sinful rapids]

yes

[crimson terrace]

hit ctrl shift F and search for "STONE_AXE"

[sinful rapids]

ok

[crimson terrace]

if there is none, build the project again and put the new jar file back into the server, then restart it

[sinful rapids]

There is not

[loud junco]

What do you think is better to use, CompletableFuture.runAsync or Bukkit.getScheduler().runTaskAsynchronously and why? Been thinking about what to use, as i'm not sure if the Bukkit Scheduler works the same as CompletableFuture.. Does it? 😄

[ivory sleet]

Doesn’t really matter if you supply the cf with a good executor

In java 19 the runAsync will be better in combination with virtual threads

[loud junco]

I just plan to fill my cache with data from mysql with it.

[ivory sleet]

Since runTaskAsync probably will stay as is with the cached thread pool

[ashen quest]

hey guys, i wanna do smth like

- every 24 hours, X player's progress resets
  - which contains
    - all the blocks they placed turning into the block that was previously there
    - there items be gone (i know how to do this)

now how do i store all blocks placed by the player effeciently

as this could get messy with like 50 players

[sinful rapids]

Im stupid... There was a script with the same command, that's why it didn't go

[eternal oxide]

why not just replace the world every 24 hours?

[quiet ice]

How far could the players move?

[ashen quest]

cuz that also resets other player progress

[eternal oxide]

Then store changes in a database

[ashen quest]

What DB would u recommend

MySQL or Mongo?

[eternal oxide]

sqlite would be fine for 50 players

[ashen quest]

no but the problem is also resetting

[eternal oxide]

why?

[ashen quest]

cuz imagine i m resetting for 10 players, all of them have like 200 blocks
and now all of a sudden i m replacing so many blocks

wont that make the server a bit slow?

at that time no one will be online if that helps

[quiet ice]

It gets messy if you allow players to move more than 2^27 blocks in either location, otherwise you can just do a Map<Player, Map<Long, OldBlock>>

[ashen quest]

whats the long for

The old location

(it would be a bitset)

[ashen quest]

Okay

hmm now shit gets messy

cuz theres container blocks

[ashen quest]

Also, why do I store the loc when OldBlock already has a way to get location?

[quiet ice]

If you are on paper you might be able to pass it through DFU

What happens if a non-reset player interacts with a block scheduled to be reset?

[ashen quest]

it just stays how the non reset player decided to

[quiet ice]

Prevent collisions

[ashen quest]

will remove it from the db

[ashen quest]

can u elaborate please

[loud junco]

what data do you think will get reset? 😄 you won't clear players inventories if you delete the world

[quiet ice]

Well if you player sets a block twice at a certain position and this thing

[ashen quest]

yea i m not deleting the world

[ashen quest]

okay

[quiet ice]

Oh yeah, and your idea does open up the window for dupes

[ashen quest]

oofus

I imported spigot remapped to mojang nms into my project and I get this error right here: java.lang.NoClassDefFoundError: net/minecraft/nbt/Tag, I tried using both reobfuscated and not reobfucated in the server.

I have checked that both the server and the plugin use the same nms version

Hi.
I'm trying to store a list of locations and I've used a File to store the data between server restarts. but im having some trouble retrieving and storing the list to a variable. I know that im retrieving the List correctly but when im trying to make it to the variable it breaks.

What ive tried:
public static List<org.bukkit.Location> DrillLocations = new ArrayList<>(); DrillLocations.addAll(FileHandeler.getFile().getList("Cords"));
And:
public static List<org.bukkit.Location> DrillLocations = FileHandeler.getFile().getList("Cords");

Where are you instancing the PlayerKits Class?

[eternal oxide]

your instance you pass is null

[tall dragon]

why not pass this?

[river oracle]

must abuse static

[tall dragon]

right

[sacred mountain]

how do i use an instanceof in a foreach/predicate

entity -> entity instanceof Player
doesnt work so idk

[tall dragon]

those are called lambda's fyi

[sacred mountain]

yeah

sry

[tall dragon]

well what ru tryna do

[sacred mountain]

this

[tall dragon]

that should work fine

        List<Entity> list = ...;
        List<Entity> players = list.stream().filter((ent) -> ent instanceof Player).toList();

for example

this works fine

[glass mauve]

you could also map it to List<Player>

[tall dragon]

yea you could

[ivory sleet]

Player.class::cast (:

And ::isInstance

[tall dragon]

how dare you use a smiley face the wrong way arround!

[ivory sleet]

🙂 yeah

Oh

I can’t do it the other way

[tall dragon]

you can

if you disable discord transforming them 😄

[glass mauve]

^

:)

:D

[ivory sleet]

Let me see

[sacred mountain]

how?

[ivory sleet]

stream.filter(Class.class::isInstance).map(Class.class::cast)

[uneven fiber]

anyone know how to set the color of some leather pants

[sacred mountain]

[ivory sleet]

collect

Or toList, depends on what implementation of list you want

[glass mauve]

yea

[tall dragon]

#toList returns an unmodifiable list

hello i want to spawn a ender dragon in overworld but it has to support changing phases and having a portal how to do that

1.17.1

[tall dragon]

uhh as far as i know enderdragons AI is disabled in overworld

[sacred mountain]

ignore the line at the top, its a duplicate method error

[tall dragon]

so would prolly take some trickery to get arround that

[eternal oxide]

The last time I spawned a dragon in the Overworld it always heads off to 0,0. But that was back in 1.7 days

[tall dragon]

nowaways it just floats still i think

iirc

[winged ridge]

I'm trying to parse an Item from an arg on a command, but I get null exception. java try { ItemStack item = new ItemStack(Material.getMaterial(args[1].toUpperCase()), Integer.parseInt(args[2])); } catch (NumberFormatException e) { player.sendMessage(ChatColor.RED + "The item " + args[1].toUpperCase() + "doesn't exist"); }
args[1] isn't null, I can print it

[sacred mountain]

uh

[ivory sleet]

No but getMaterial can return null iirc

[sacred mountain]

Returns:
Material if found, or null

[winged ridge]

yeah but it doens't send the message to the player

[ivory sleet]

Anyway you should favor matchMaterial

[tall dragon]

and the action you take after an exception is wrong too

[ivory sleet]

It’s much kinder

[winged ridge]

ok let me try

[tall dragon]

you send them a message the item doesnt exist

while really they didnt enter a correct number

[ivory sleet]

Yes because the NPE terminates the execution

[uneven fiber]

anyone know how to set the color of some leather pants

[tall dragon]

use LeatherArmorMeta

[desert tinsel]

try Material.valueOf(args[1])

[uneven fiber]

👍

[sacred mountain]

marerial

[ivory sleet]

Don’t

[sacred mountain]

matchMaterial

[ivory sleet]

That’ll just explode upon misinput

[sacred mountain]

Attempts to match the Material with the given name.
This is a match lookup; names will be converted to uppercase, then stripped of special characters in an attempt to format it like the enum.

[winged ridge]

that also throws a null exception

[sacred mountain]

you dont need to worry about uppercasing that

then your command args are wrong

[ivory sleet]

Literally not

[tall dragon]

make the player input a number and choose a material from the ordinal 😄

[ivory sleet]

ItemStack(null) throws NPE

[sacred mountain]

btw

commands args start from 0

not 1

[ivory sleet]

Because it doesn’t make sense for the material of said stack to be null

[winged ridge]

i know

[desert tinsel]

Material.valueOf(args[1].toUpperCase())

[sacred mountain]

mk

[sacred mountain]

no

[ivory sleet]

Stop

[winged ridge]

oh that's maybe why

[ivory sleet]

Yes

You should cache matchMaterial into a variable, null check the value of the variable and if not null then continue

[sacred mountain]

?

[ivory sleet]

Yes

[sacred mountain]

i tried \d and it doesn't work

[glass mauve]

\d means digit

[ivory sleet]

\d

\\d

[glass mauve]

like 0-9

[winged ridge]

alright

[ivory sleet]

Since you need to escape the escape character

[tall dragon]

actually thats not entirely correct

[sacred mountain]

?

[ivory sleet]

Yes

[sacred mountain]

aight

i've always used 0-9 ;lol

[tall dragon]

[0-9] will match 0 to 9 as it sais, \d will match any number so also latin numbers and stuff

[ivory sleet]

Latin numbers?

[glass mauve]

I, II, III, IV etc

[tall dragon]

idk there are weird numbers

[sacred mountain]

thats

roman numerals

[tall dragon]

those will be matched by \d as well

[sacred mountain]

unless im stupid

[tall dragon]

or i am confused with \w

[sacred mountain]

whats latin numbers

[tall dragon]

XD

[ivory sleet]

Yes you’re

\d is literally equivalent to [0-9] by definition

[sacred mountain]

is there a difference

[ivory sleet]

No

[sacred mountain]

ok

[ivory sleet]

They’re equivalent

[tall dragon]

in \w there is a difference tho

[ivory sleet]

Ye

[tall dragon]

between \w and [a-zA-Z]

[glass mauve]

[A-Za-z]

[ivory sleet]

\w is like [a-zA-Z0-9]

[sacred mountain]

thx

[tall dragon]

and it will also match arabic characters and stuff

iirc

[ivory sleet]

In Java I don’t think so, maybe tho

For Latin shit there’s another one

[ashen quest]

arabic characters only or like chinese and hindi and everything as well

[ivory sleet]

Like \p{IsLatin} or sth

[tall dragon]

pretty sure everything

[subtle folio]

Does ChatColor#of() translate colorcodes like & and hex values?

[ashen quest]

o

[ivory sleet]

^

Not Arabic then

But . can be used

[ivory sleet]

Yes

[ashen quest]

btw whats the _ for

[ivory sleet]

&x&f&f&f&f&f&f is equivalent to white

For instance

[glass mauve]

https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/regex/Pattern.html

[tall dragon]

only latin characters then

https://gyazo.com/207ed4ebeb30fecca97be6d159a4318e

[sacred mountain]

some methods i made to find players, any way to improve or nope

[ivory sleet]

By convention you should use Predicate<? super Player> such that an instance of Predicate<HumanEntity> could be passed

But looks fine

I would avoid streams

[sacred mountain]

okay

[glass mauve]

why?

[ivory sleet]

Since they’re not yet competitive with normal loops

[sacred mountain]

was suggested to me by 7smile

[ivory sleet]

And those methods look like they would be executed arbitrarily during runtime post bootstrap

[glass mauve]

streams are really useful

[ivory sleet]

So are loops

[glass mauve]

but ugly

[sacred mountain]

yes

ugly

lambdas look hot

[ivory sleet]

You don’t use lambdas cause they’re hot tho

[sacred mountain]

well yes

[ivory sleet]

No

[glass mauve]

well no

[hasty prawn]

I do wdym

[sacred mountain]

lmao

[ivory sleet]

You’d use them because they tend to abstract or avoid side effects

[sacred mountain]

• they're hot

[hasty prawn]

^

[ivory sleet]

literally doesn’t matter

[sacred mountain]

¯_(ツ)_/¯

[opal juniper]

i use streams cause they make a huge multi step problem a one line issue

[ivory sleet]

Streams as of now scale significantly worse than loops

Well if you wanna be clean just extract a method with the loop like any clean coder would do

[tall dragon]

by smile's logic, 1 line = faster 😄

[opal juniper]

they are slower but i accept that

[sacred mountain]

yez :D

[glass mauve]

same, but depends on the use case

[sacred mountain]

i mean

on a scale of a minecraft plugin

[hasty prawn]

My guess is that in this case the performance difference of streams and loops isn't going to matter.

[ivory sleet]

Yea for bootstrapping and termination it’s fine to use streams

But they really suck ass right now when it comes to performance since it has to switch on the terminal operation type and sometimes can’t evaluate lazily

[sacred mountain]

whats the actual speed difference

[ivory sleet]

And + all the extra object allocation

Do some benchmarks

[sacred mountain]

nanotime? or is that useles

or just system milliseconds

[glass mauve]

but pls use good java benchmarks

[ivory sleet]

But it’s a bit hard to bench mark individual methods as sometimes they’re lazily evaluated

[glass mauve]

use org.openjdk.jmh

[ivory sleet]

Anyway light fury thats what I would say, go with a loop, or at least get rid of the stream, you can create some hacky for each higher order function if you want to

if you’re in love with javas lambda syntax ig

[sacred mountain]

aight ok

lmao it was a joke

but yeah thx

[ivory sleet]

No it’s fine

A lot of people have that opinion apparently

[glass mauve]

but the performance difference between forloop and streams are not that high

[ivory sleet]

Depends on how you scale it

And what operations you do

[tall dragon]

in some critical systems every little bit counts though

[glass mauve]

but makes code less readable

[ivory sleet]

Like, streams are worse in terms of both space and time

No it doesn’t

It reduces boilerplate tho

But that’s different

[lethal roost]

can someone explain what this does exactly? i'm not sure if my understanding of this line matches to what the docs mean https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/InventoryAction.html#PLACE_ALL

because my code isn't working the way i think it's supposed to work

[eternal oxide]

In an InventoryClickEvent this would be the InventoryAction if you were putting a stack into a slot.

[lethal roost]

so with this code, it should message the console whenever i place a wooden axe in my inventory, right?

[crisp steeple]

no, you never check what the type of the item is

[lethal roost]

oh yeah right

well but any object then

ah

lemme try that then

ty

[quaint mantle]

is getVersion() and getBukkitVersion() the same?

[opal juniper]

no

[lethal roost]

ok i've done some testing, with this code, the message pops up both whenever i place everything from my cursor down in my inventory and when i pick it up, which makes no sense
does anyone know why?

[river oracle]

Version = plugin Version
BukkitVersion = server Version

[quaint mantle]

oh okay didn't knew that

thanks

[opal juniper]

wrong

[river oracle]

Wrong?

What Is version then

[opal juniper]

get version is - Gets the version string of this server implementation.

[river oracle]

Mb

[lethal roost]

and the console doesn't say anything at all with this code even after i tried clicking on a stack of items, one item, etc in my inventory

is there a reason for this?

[tall dragon]

nope

but for items you can use Nbt as an alternative

idk what ur tryna do

[high eagle]

Anybody know what has happened to EpicWorldGenerator, is it still supported?

[dire marsh]

no

[high eagle]

No it's not or you don't know.

It say I can still buy it for $20.00USD.

[dire marsh]

the author hasn't cared about ewg for 2 years

[dire marsh]

it's in inactiveresource

you can't purchase it

[high eagle]

I know.

It's terriblay.

Any other alts?

[dire marsh]

terra, realisticworldgenerator, iris

[high eagle]

Respec. Thanks man those are free resources and not only that they look substantially better than EWG.

[lethal roost]

terra is very good i can confirm 😏

[high eagle]

Dude the .jar name is incredibly long.

It looks sorta scuffed.

But I know it's safe.

[lethal roost]

ok

[sacred mountain]

ok

[high eagle]

Since nobody else would help me with my server. Would you?

[trail lintel]

Hey guys, I am having some trouble with the getLineOfSight function. I want to only get water SOURCE blocks, but it takes a material list for its "transparent blocks". Well, water is no longer differentiated by the two material types WATER and STATIONARY_WATER, I have to use a Levelled block instance. How can I approach this? My getLineOfSight is returning flowing water blocks, when I want it to look through them =[

I'm guessing the only option here might be to use a Raycast with a predicate to filter out the non-source blocks? Would like to stick with getLineOfSight if possible though for simplicity

Oh 😮

looks like raycast blocks has a FluidCollisionMode option, can take SOURCE_ONLY 😉

[dire sand]

Hey guys

I am looking to spawn hollow falling blocks

How can I make them hollow?

[twilit roost]

How to get if player is holding A/D key?

[trail lintel]

dont think you can get what keys the player is holding

you can tell that they are sneaking or sprinting, thus kinda getting ctrl and shift, im not 100% though there might be a way

[twilit roost]

i thought of MoveEvent
but that can lag the crap out of the server..

[ocean lion]

Does anybody know a good ScoreboardApi?

I'm looking for a plugin that won't allow me to pick up creative from articles, help me pls

[sacred mountain]

what is articles

and 'pick up creative'

and this also isnt the right channel

hey is there any good way to shorten/clean this up?

[silver pulsar]

Hi.
I'm trying to store a list of locations and I've used a File to store the data between server restarts. but im having some trouble retrieving and storing the list to a variable. I know that im retrieving the List correctly but when im trying to make it to the variable it breaks.

What ive tried:
public static List<org.bukkit.Location> DrillLocations = new ArrayList<>(); DrillLocations.addAll(FileHandeler.getFile().getList("Cords"));
And:
public static List<org.bukkit.Location> DrillLocations = FileHandeler.getFile().getList("Cords");

[sacred mountain]

are you sure the path is right

what does your yaml look like

[silver pulsar]

yaml:
`Cords:

• ==: org.bukkit.Location
  world: world
  x: 1.0
  y: 119.0
  z: 0.0
  pitch: 0.0
  yaw: 0.0
• ==: org.bukkit.Location
  world: world
  x: 0.0
  y: 119.0
  z: 0.0
  pitch: 0.0
  yaw: 0.0
• ==: org.bukkit.Location
  world: world
  x: -1.0
  y: 119.0
  z: 0.0
  pitch: 0.0
  yaw: 0.0
  Test:
• Hello
• World
  LoremIpsum: Test
  `

[silver pulsar]

yes i tried printing it with toString() and it worked

[sacred mountain]

don't you need to deserialize

[silver pulsar]

what does that mean?
im new to java

[sacred mountain]

how did you set the locatoin in the config

config.set("path", Location)

[silver pulsar]

DrillLocations is a ArrayList of org.bukkit.Location
DrillLocations.add(event.getBlock().getLocation()); FileHandeler.getFile().addDefault("Cords", DrillLocations);

[lost matrix]

This should 100% not be a switch statement but a map

[sacred mountain]

aight ok

wdym a map

HashMap<String, Object>

or <string, string>

[lost matrix]

Either <String, String> or if you want to use the calls instead <String, Supplier<String>>

[sacred mountain]

and just have a getter

those values change though,

how often do i update this map

runnable async?

[lost matrix]

Data structures like lists, sets and maps should never have getters or setters. This breaks strong encapsulation and leads to very messy code.

[sacred mountain]

i meant map.get not an actual getter method sorry

[trail lintel]

aye guys, im marking an entity for removal with Entity.remove(), but afterwards it leaves a ghost of the entity that stands in place and whos collision box still affects the player

[lost matrix]

You simply create the map once and fill it. You can have something similar to a method in a Map. Ill give you and example.

[trail lintel]

disconnecting and reconnecting removes it, is this a known thing?

[sacred mountain]

yeah but values update

[lost matrix]

The value is a method. You never update it.

[sacred mountain]

do you mean putting the BukkitUtils.methodHere() inside the map?

but wont htat be equivalent to putting an actual value in the map

[twilit roost]

How to get direction that player moved in?

[sacred mountain]

when

player moved in? contexrt

[sacred mountain]

uh?

still don't understand

i'd appreciate some kind of example if you can

[lost matrix]

  private final Map<String, Supplier<String>> placeholderMap = new HashMap<>() {{
    this.put(SERVER + "version", () -> BukkitUtils.getServerVersion());
    this.put(SERVER + "version_tab", () -> BukkitUtils.getVersion());
    this.put(SERVER + "name", () -> BukkitUtils.getServerName());
    ...
  }};

  public String onPlaceholderRequest(Player player, String placeholder) {
    if(player == null) {
      return null;
    }
    return placeholderMap.getOrDefault(placeholder, () -> null).get();
  }

[sacred mountain]

oh i see

so not putting the actual method, putting the value of the method at the time

of getting the value

[lost matrix]

Or to be more clear on what is happening:

  public String onPlaceholderRequest(Player player, String placeholder) {
    if(player == null) {
      return null;
    }
    Supplier<String> supplier = placeholderMap.getOrDefault(placeholder, () -> null);
    return supplier.get();
  }

[sacred mountain]

should i put it in the main class¿

the map i mean

[lost matrix]

2 ways.
PlayerMoveEvent -> Build a vector from "from" to "to"
Player -> get his velocity

[lost matrix]

Nope.

[sacred mountain]

in the same class then as a private method

private map

not method

[lost matrix]

Yeah the map should be invisible to anyone else unless you want to let others register placeholders as well.
So putt it in the class that also contains the method.

[halcyon mica]

Is there an easy way to get the direction a player is looking at, and get the oposite of it?

Only yaw

[sacred mountain]

couldnt i use a method reference

instead of hte lambda

[lost matrix]

Sure.

  public Vector getBackwards(Player player) {
    return player.getEyeLocation().getDirection().multiply(-1);
  }

Thats the vector. You can figure out the yaw from there.

[sacred mountain]

or no

[lost matrix]

Sure you can also use method references.

[halcyon mica]

But that only signs it negatively

-45 is not the oposite of 45

[sacred mountain]

no you're multiplying the vector by -1

its like

[lost matrix]

  private final MessageService messageService = new MessageService();
  
  private final Map<String, Supplier<String>> placeholderMap = new HashMap<>() {{
    this.put(SERVER + "version", () -> BukkitUtils.getServerVersion());
    this.put(SERVER + "version_tab", () -> BukkitUtils.getVersion());
    this.put(SERVER + "name", () -> BukkitUtils.getServerName());
    this.put("coolname", this::getCoolName);
    this.put("msg", msgService::getMessage);
    ...
  }};

  public String onPlaceholderRequest(Player player, String placeholder) {
    if(player == null) {
      return null;
    }
    Supplier<String> supplier = placeholderMap.getOrDefault(placeholder, () -> null);
    return supplier.get();
  }

  private String getCoolName() {
    return "Bob";
  }

There you go. One local method reference and one from another class instance.

[sacred mountain]

scalars

[sacred mountain]

neat, thanks

[lost matrix]

This gives you the exact opposite vector of the players eye direction.

[sacred mountain]

i love the alt key 😍

[lost matrix]

For just the yaw. Not sure if it works.

  public float getBackwardsYaw(Player player) {
    float currentYaw = player.getEyeLocation().getYaw();
    return (currentYaw + 180F) % 360;
  }

[halcyon mica]

The plan is faily simple

        Vector invertedView = player.getEyeLocation().getDirection().multiply(-1);
        float yaw = (float)Math.atan2(invertedView.getX(), invertedView.getZ());
        if(data.dirLocked()) {
            // Snap to a cardinal direction
        } else {
            // Set rotation to face the player
        }```

[halcyon mica]

Snapping is the issue though, idk if I can use the minecraft direction implementation which I know for a fact can go off of an angle

[sacred mountain]

snapping?

[green prism]

How to create a paginated help menu like /help 1/2/3...? With 10 obj for each page?

[sacred mountain]

dynamic locations should fix yaw and pitch stuff

[trail lintel]

anybody got any idea why when I mark an entity with .remove(), it glitches client side and creates a frozen copy of the entity? reconnecting fixes it

[sacred mountain]

remove it with a packet ? idk much about packets tho

you could send it to the player after

removing it serverside

[trail lintel]

hmm, it seems weird that is even necessary when there is that remove function o.o

figure it would handle sending those packets

[sacred mountain]

yeah as i said im not sure, ill check gimme a sec

[ocean lion]

Is there any 'right way' when it comes to making GUIs. I feel like I always make it overcomplicated and really messy.

[spice remnant]

how to use 1.19 nms?

java.lang.NoSuchMethodException: net.minecraft.network.chat.ChatMessageType

[lost matrix]

Yes. Delegation is key.

[lost matrix]

https://www.spigotmc.org/threads/spigot-bungeecord-1-19.559742/
Scroll down to "NMS"
Since 1.17 nms works differently

[sacred mountain]

essentialsx uses the default e.remove()

and that works fine, what does your code look like

[lost matrix]

Meaning you should have a Consumer<InventoryClickEvent> or something similar somewhere in your pipeline.

[trail lintel]

hmm so they do, ill post a snippet here RQ

[sacred mountain]

then again essentials is a big project so they might have some handler elsewhere that manages that

[lost matrix]

It does. When you call .remove() on an entity then it will be removed like when it would despawn.

[trail lintel]

@EventHandler
public static void BucketEntityEvent(PlayerBucketEntityEvent event) {
  ItemStack original = event.getOriginalBucket();
  if(ItemManager.isBetterBucket(original.getItemMeta())) {
    if(ItemManager.interactableEntities.contains(event.getEntity().getType())) {
      original.setItemMeta(ItemManager.setContentType(original.getItemMeta(), ContentType.valueOf(event.getEntity().getType().name())));
      ItemManager.updateItemStack(original);
      event.getEntity().remove();
      // TODO: Should not just set main hand
      event.getPlayer().getInventory().setItemInMainHand(original);
    }
  event.setCancelled(true);
  }
}

cleaned it up a bit for ya

you can see I am cancelling the event, and removing the relevant entity

but the remove leaves a "ghost" client side, reconnecting fixes it though

[lost matrix]

Remove the entity one tick later

[trail lintel]

ohhhh interesting idea 😮

not quite sure how to do that atm, will do some googling 😄

[sacred mountain]

bukkit runnable

[chrome beacon]

?scheduling

[undone axle]

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

[sacred mountain]

runTaskLater

[trail lintel]

ayee thanks you guys, gonna try this will update with results

[lost matrix]

Bukkit.getScheduler().runTaskLater(yourPlugin, () -> event.getEntity().remove(), 1L);

[spice remnant]

what if im using grade?

!spigotmain: Could not find org.spigotmc1.19-R0.1-SNAPSHOT.
Required by:
project :spigot

[chrome beacon]

?bt You still need to run BuildTools

[undone axle]

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

[chrome beacon]

Also you won't be able to remap

So either use Paper userdev or use unmapped NMS

[lost matrix]

Tricky. You need to do some research because the special sources plugin is maven only iirc.
For gradle projects i just used the userdev plugin from Paper 😅

[sacred mountain]

yo 7sm how would i put this in the map?

should i just keep that in the placeholderrequest

try the first one and if thats null try this else return params

[lost matrix]

I think that would be the best sollution

[ornate patio]

does anyone know the range of horse speed, jump strength, and max health possible

like the natural range when spawning in

[lost matrix]

Horse's movement speed ranges from 0.1125–0.3375 in internal units, with an average of 0.225.

[trail lintel]

@sacred mountain @lost matrix it worked! delaying by 1 tick made the ghosting effect go away, you guys rock

that was the biggest bug preventing me from finishing up this plugin for our server =] thanks a bunch

[ornate patio]

ive seen this online but i didn't believe it.. I tried out 0.1125 and i have never in my life seen a horse so slow

to the point where you can sprint faster than it

[sacred mountain]

unless you put the horse on drugs

[ornate patio]

i also saw jump strength is 0.4-1.0, but at 1.0 the horse can jump 5.25 blocks and I also have never seen that before

welp i was just checking then

[trail lintel]

ok one final question 😉

[sacred mountain]

okay

[trail lintel]

is there a way to get the center of a block from the Location object? I want to spawn an entity in the center of a block rather than right on the corner

I could just add .5 to each, but figure there might be a function already

[ornate patio]

pretty sure you just have to do Location#getBlockX() + 0.5

[trail lintel]

block.getLocation().add(.5, .5, .5) 😉

[ornate patio]

ye that works

[humble tulip]

Yep

Mqke a func for it

[sacred mountain]

one last thing, would it be better to store the object in the supplier instead of just the string? then i can do other things if needed

i dont like people who dont put a 0 before the decimal point

playerfishevent?

or no

[humble tulip]

Maybe add 1 to the y depending

[ornate patio]

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

[sacred mountain]

i was right

lmao i guessed

[trail lintel]

ohh yeah thats a good point, since spawning on TOP of blocks will need a full Y

[sacred mountain]

() -> null is just getting the value, else return null right?

placeholderMap.getOrDefault(params, () -> null).get()

[humble tulip]

Or u may need to add 0

Again depending

If the block is air add 0 if it's solid add 1

[tardy delta]

why getOrDefault(key, null), thats the default implementation for get(key)

[trail lintel]

story of my time learning to dev for spigot haha, always another very specific scenario you have to account for if you overriding normal game behavior through event cancels

having to cancel all the regular bucket interact events because they replace the item meta, so doing all this bucket logic in the interact events

[crude loom]

Hi, I'm new to packets and I'm trying to use the entity move packet
If I understood correctly, using ProtoclLib it should be the PacketType.Play.Client.POSITION
How do I get the information about it though? like what variables can I get out of it (I'm asking where can I find this on google)

[sacred mountain]

ask 7smil

i didnt write htat

there's got to be a better way of doing this

[tardy delta]

make the return value of get a variable lol

and do toString

[sacred mountain]

ok

[halcyon mica]

Can texts not escape UTF characters?

I am trying to set ▮ into a motd

And it just corrupts it

I can set it through code though

Also, different question

How do I rotate a armorstand, as in the entity itself?

Just setting y rot and x rot does nothing

[sacred mountain]

you need to telelport it to the same location, changed direction

i think location has the direction builtin so you just need to do armorStand.teleport(updatedLocationWithDirection)

[halcyon mica]

I have set the rotation before spawning the entity though

[pale egret]

I need help, when I did sudo apt install openjdk-14-jre-headless I got this error: 'openjdk-14-jre-headless' has no installation candidate

[sacred mountain]

iirc you need to use radians

Math.toRadians(yourDegreesHere)

EulerAngle(Math.toRadians(yourDegreesHere) , yDegrees , zDegrees)

[humble tulip]

?protocol

[sacred mountain]

bukkit has that builtin

i used it for particles

[pale egret]

anyone know why that happened? I'm using ubuntu

[sacred mountain]

this isnt hte place to ask

[halcyon mica]

Nope, that is still not it

[sacred mountain]

did you use

[humble tulip]

https://wiki.vg/Protocol

[sacred mountain]

armorStand.setHeadPose(new EulerAngle(Math.toRadians(blah), y, z))

[halcyon mica]

No, I am trying to rotate the entire entity

Not just the head

[sacred mountain]

setRotation?

[humble tulip]

Well u need to use yaw or pitch

[sacred mountain]

i think they already did that

[humble tulip]

Not for thebhead

For the armorstand itself

[halcyon mica]

A nms armorstand has no setrotation function

just a set yrot and setxrot

Which I am using

[sacred mountain]

it inhertis the entity class tho

its also in the javadoc

oh nms

the bukkit api has stuff tho

[halcyon mica]

I am using a nms entity to fake packets

Can't really do that with bukkit entities unless I cast like 3 times in the process

[sacred mountain]

why woukd yioyu need to cast 3 times

[quartz basalt]

i am very confused... if (land.getOwnerUID() != p.getUniqueId()) { Bukkit.broadcastMessage("owner " + land.getOwnerUID() + " player " + p.getUniqueId()); p.sendMessage(ChatColor.translateAlternateColorCodes('&', "&7You do not own this claim")); i need to make a thing that checks if land.getowner and p.getunique are different but this ALWAYS triggers which makes no sense because when i broadcast the 2 they are the exact same so why is this happening

[quiet ice]

Use .equals

!= uses instance comparision

[halcyon mica]

Because a lot of things I am accessing are not abstracted by bukkit

[quiet ice]

Or however you call it

[sacred mountain]

Objects.equals(a,b)

[halcyon mica]

So I would need to go between a craftbukkit and nms entity constantly

[quartz basalt]

ah ight ty

[green prism]

Guys, please help.
How can I close these two PreparedStatment and ResultSet?

    public HashMap<Integer, String> getValues() {

        try {
            PreparedStatement ps = plugin.getMySQL().getConnection().prepareStatement("SELECT * FROM agencies");
            ResultSet rs = ps.executeQuery();
            HashMap<Integer, String> values = new HashMap<>();
            while (rs.next()) {
                values.put(rs.getInt("ID"), rs.getString("AgencyName"));
            }
            return values;
        } catch (SQLException e) {
            if(e == e.getNextException())
                return null;
            e.printStackTrace();
        }
        return null;
    }```

[quiet ice]

!= is only appropriate when comparing primitives and enums, but not much more unless you know what you are doing

[sacred mountain]

or instances

[ocean lion]

 Player whoToTarget = player.getServer().getPlayerExact(ChatColor.stripColor(event.getCurrentItem().getItemMeta().getDisplayName()));

How would I access whoToTarget from else if statement under

[quiet ice]

This also applies to wrapper classes, Integer.valueOf(5926) == Integer.valueOf(5926) will return false for example

[sacred mountain]

define it above

[green prism]

Player whoToTarget;
if() {
//
} else //

[sacred mountain]

i forgot the word for it

theres like instantiation, assignment and seomthing

declaration?

or was the first one initialization

[green prism]

Elgar, help pls

[eternal oxide]

try (PreparedStatement ps = plugin.getMySQL().getConnection().prepareStatement("SELECT * FROM agencies")) {```

[green prism]

and then I close it in a finally right? Thanks!! I hadn’t thought about it!

[eternal oxide]

PreparedStatement is AutoCloseable

[green prism]

ah

[eternal oxide]

no, that will close it when its finished

[quiet ice]

Object o; // Declaration
new Object(); // Instantiation
o = x; // Assignment

[sacred mountain]

yez

[green prism]

A friend of mine told me that it is better to close things when talking about actions that interact with the outside (in this case with the database) because the GC does not insure the outside in fact

I didn’t know, thank you so much again Elgar! You’re giving me a great helping hand in learning mysql & java!

[eternal oxide]

in a try with resources once you exit the scope of the try it will auto close anything in the try (...)

[green prism]

I understand, thanks thanks thanks

[rare flicker]

where should i report spigot bugs?

[green prism]

Forum I think

[eternal oxide]

?jira

[undone axle]

https://hub.spigotmc.org/jira/secure/Dashboard.jspa

[rare flicker]

thx

has to do with the way an item gets saved to a YamlConfiguration

theres a name missmatch for enchantments

still works just doesnt make sense

[green prism]

Hey elgar, do you know how to create a paginated menu? Like /help 1, 2, 3... with some dynamic values?

[sacred mountain]

when i print a normal string with \u2713 in it, will it automatically convert it to a symbol in the console?

[rare flicker]

(efficiency is stored as SILK_TOUCH for eg)

[quiet ice]

"Working as intended"

[eternal oxide]

You'd probably be best to look at teh Essentials help menu source for that

[green prism]

Uhh! Thanks!

[sacred mountain]

will this work

or can i literally just do this

[quiet ice]

that is a very strange way of doing it

i.e. I have never seen that syntax

[eternal oxide]

Either will work, but correctly private final String claimedPlot = "\u2B1B";

[sacred mountain]

oh right

so without the brackets

why is it an emoji bruh

that looks so ugly

[quiet ice]

what do you mean?

Blame your character set if you are complaining about what I think you are complaining

[sacred mountain]

how do i even change that

[quiet ice]

Adopt vim I guess

[quartz basalt]

how do i get all the contents from a specific enum here https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/CreativeCategory.html when i do CreativeCategory. it has a list of enums but i cant use CreativeCategory.<enum>.values()

[quiet ice]

I know that eclipse has a way of chaning the fonts that are used but idk how IJ works so yeah - you'd need to use vim

[quiet ice]

What do you mean by contents?

[ocean lion]

Caused by: java.lang.NullPointerException: Cannot invoke "org.bukkit.entity.Player.setHealth(double)" because "this.whoToTarget" is null

[quartz basalt]

oh wait im dumb mb just reliased

is it possible to get all the specific items from a specific creative category like all the redstone items for example

[quiet ice]

I think that was always a bit of magic

[neon nymph]

In an attempt to store a key-value pair in an ordered list, instead of using LinkedHashMap, I created my own simple Pair<K, V> class and did this instead ArrayList<Pair<K, V>>. In this approach, I could easily get the last entry anytime I want using the arraylist indices instead of having to iterate over every entry in LinkedHashMap, costing me like O(n). Is this approach feasible?

[quiet ice]

Feasible, yes - does it makes sense? I do not know

[neon nymph]

Well originally I wanted to have an ordered list of two variables, and thought of pairing them together instead to simplify things

[silver pulsar]

Hi.
I'm trying to store a list of locations and I've used a File to store the data between server restarts. but im having some trouble retrieving and storing the list to a variable. I know that im retrieving the List correctly but when im trying to make it to the variable it breaks.

What ive tried:
public static List<org.bukkit.Location> DrillLocations = new ArrayList<>(); DrillLocations.addAll(FileHandeler.getFile().getList("Cords"));
And:
public static List<org.bukkit.Location> DrillLocations = FileHandeler.getFile().getList("Cords");

[latent heron]

Anyone know a plugin or something so like when a player presses like E on their keyboard it executes a command?

[sacred mountain]

ryan ask in #help-server

[latent heron]

thanks

[quiet ice]

You are sacrificing O(n) .get complexity for O(1) .getLast performance, so be aware of that

[sacred mountain]

big o notation"?'/

[neon nymph]

Well, isn't that a good thing? I'd go for constant time any day compared to potentially longer time

Since my list is gonna be big, like 100+

[quiet ice]

.get is now more expecsive

At least the map-like get

The list-like get is now O(1)

[neon nymph]

It's always been cuz of the indices

That's why I used arraylist instead of LinkedHashMap, the latter didn't have .getLastEntry() or something similar

I need the last entry most of the time lol
