[tribal sparrow]

i know, i'm using a runnable but its setting all blocks that are on fire to air

[wraith rapids]

then just set the one specific block to air

[digital plinth]

so the blocks that are fire

[wraith rapids]

instead of all of them

[digital plinth]

not the fire block

wait what are you trying to do here

extinguish multiple fires or just one

[tribal sparrow]

just the one.

so a projectile hits a block, sets it on fire
that fire goes for 15 seconds
after 15 seconds i'm trying to extinguish the fire, but only the fire. not removing the blocks. yes i know some blocks burn within that 15 seconds that's fine though

[wraith rapids]

set the fire block to air

[hardy swan]

Can block at 255 be set on fire on the top

[wraith rapids]

no because the fire would have to occupy 256 which exceeds the world size

fire isn't an entity; it's a block and needs to occupy an entire block of space

[digital plinth]

i wonder is the fire will go out before 15 secs

like natrually

or burn the block away

[digital plinth]

projectilehit -> getLoc,set fire, execute the runnable and feed the location of the fire block to it so it can set the block to air in 15 sec

i will not extinguish all fires if you do it correctly

[tidal ferry]

is there a way to make a line of code where there are no tall grass blocks in the world

[wraith rapids]

very difficult to do in a single line of code

[tidal ferry]

not on a single line sry

like just is there a way

[wraith rapids]

remove the block populator that spawns them from the generator

[digital plinth]

yes there is a way

[tidal ferry]

idk how to do that

[wraith rapids]

then you should learn how to do that

[digital plinth]

or set all tallgrass to air on chunk load (worse method, probbaly easier?)

[digital plinth]

🤣

[tidal ferry]

how

[digital plinth]

google.com

[tidal ferry]

...

bru

[digital plinth]

bru indeed

[wraith rapids]

spoonfeeding is frowned upon

[digital plinth]

omg i cant believe NNY the 7 years old know about the generators

:0

[digital plinth]

aww online chat is no fun

cant see live reactions

[tribal sparrow]

                                for(Block nearby : getNearbyBlocks(block.getLocation(), 15)) {
                                    if(nearby.getType() == Material.FIRE) {
                                        if(nearby.getBlockData() instanceof Fire) {
                                            //Fire fire = (Fire) nearby;
                                            //fire.setAge(15);

                                            nearby.setType(Material.AIR);
                                        }
                                    }
                                }
                            });```
so checking to see if the block is instance of Fire and the material still removes that block thats currently on fire (under the Fire)

[dusk flicker]

So what's the goal

Or I should say problem

[tribal sparrow]

Trying to put out the fire after 15 seconds and not remove the blocks that are under the fire when setting the fire to Material.AIR. as some of the blocks may not have been 100% burnt at the end of that 15 seconds.

what i've currently got now works but it also removes the block that the fire is sitting on

[dusk flicker]

So you don't want to remove the block the fire is on?

Or do you? Bit confused

[tribal sparrow]

correct, i don't want to remove it

[dusk flicker]

Alright so when you set the nearby to air it's removing the block underneath?

[tribal sparrow]

yeah, all blocks that are on fire get removed plus the block that the fire sits on.

[dusk flicker]

What version are you running for the server

[tribal sparrow]

1.16.4

[wraith rapids]

why are you running .4

[tribal sparrow]

it's what my test server has been running on for a while, i'll update it and see if that fixes

[wraith rapids]

it probably won't

[dusk flicker]

I don't think upgrading will fix but you wan to upgrade .5 added stability fixes

[tribal sparrow]

that's why i didn't update it haha

ill try .5 now

[wraith rapids]

i super vaguely do remember hearing someone mentioning something about some strange vanilla logick that'd consider a burning block as burnt when the fire on top of it is removed manually

[dusk flicker]

Honestly I don't know what the issue is with the fire thing as the fire javadocs are fucking shit

[tribal sparrow]

i thought casting it to Fire from the blockData and setting the age would work

[dusk flicker]

Literally the description of Fire is md_5's mixtape

[tribal sparrow]

yeah i seen that

[dusk flicker]

Gonna see if paper docs offer any better info

[tribal sparrow]

thank you for your help and everyone else

[dusk flicker]

It does not.

[wraith rapids]

they generally don't care to touch up the shit that spigot left to rot

[tribal sparrow]

ill just settle for what it does now, thank you everyone

[wraith rapids]

only the new stuff has proper docs

[dusk flicker]

Def try .5, see if that helps, if it doesn't try paper possibly as maybe they have a fix for it

[tribal sparrow]

alright

[high pewter]

Still not found any reason why this could be happening. Anybody got any ideas?

[steel gulch]

i want to make a plugin for 1.7.10 does anyone have a link for the right spigot download

[haughty musk]

Hi. I am working on a plugin.. I have the following code in my onjoin() event and I was wondering if anyone can help me figure out how to get this to work>?

[sullen marlin]

What is not working

[haughty musk]

the teams dont show up in team list or tab menu

[sage swift]

why is your name red

is that bad

are you banned from spiget

[haughty musk]

so do you guys know how to fix it or do it another way?

[haughty musk]

Got it to show up just gotta get it to show the prefix

on tab menu

which still doesnt seem to work for some reason

[real spear]

How do I create multiple servers on one host? Like what minigame servers have. (making a minigame plugin rn and need to switch between servers)

[craggy osprey]

#help-server

[haughty musk]

ok just refreshed the plugin and it no longer makes the teams

[maiden shore]

Is it possible to add log4j settings for the Bukkit logger from a plugin? I'm trying to silence logs from a specific package but I can't find a way to add the log4j setting in the plugin itself

[granite stirrup]

i found out when you use the thing to simulate another device in devtools on google it actually sends to the website that your on mobile

this is the javascript lmao https://paste.md-5.net/raw/nejeyoyuxa.js https://paste.md-5.net/nejeyoyuxa.js

i found this online

lmao

[rugged topaz]

    public static void updateScoreBoard(Player p) {
        if (CitizensAPI.getNPCRegistry().isNPC(p)) {
            Bukkit.broadcastMessage("npc"); // this doesn't get called, i guess NPCs aren't included in bukkit's getonlineplayers method
            return;
        }
        Objective health = score.getObjective("showhealth") == null ? score.registerNewObjective("showhealth", "health") : score.getObjective("showhealth");
        if (health.getDisplaySlot() != DisplaySlot.BELOW_NAME) health.setDisplaySlot(DisplaySlot.BELOW_NAME);
        health.setDisplayName(SkyblockBasics.replaceChatColors("&c❤"));

        p.setScoreboard(score);
}

for (Player p : Bukkit.getOnlinePlayers()) {
    Scoreboard.updateScoreBoard(p);
}```

is there any way to fix this with citizens NPCs https://prnt.sc/n8ph6k

[granite stirrup]

dont worry about the cringe console.logs

just for debugging

[granite stirrup]

not possible

unless you had a custom client

[rugged topaz]

hypixel and several other servers do it

[granite stirrup]

they dont

[rugged topaz]

oh yea?

lemme send u an ss

[granite stirrup]

well its not possible

[rugged topaz]

or ykw

npc to my right

healthbar on me and everyone else

[granite stirrup]

i believe it showed for me so maybe thats badlion or whatever client your using doing that

[rugged topaz]

lunar client, nah. i'll show you on vanilla too if you'd like

sec

[granite stirrup]

but let me tell you its impossible cuz the above name scoreboards are client sided all the info is grabbed from the server

[rugged topaz]

player to my right with healthbar, npc further forward with no healthbar

i'm on vanilla

so, it is possible one way or another

[granite stirrup]

it isnt tho

[rugged topaz]

i'm legit showing you

[granite stirrup]

ok but hypixel uses a custom server

its not spigot or paper

its modified

[rugged topaz]

then that means nms would do the job?

[granite stirrup]

no

[rugged topaz]

i'm stumped

[granite stirrup]

its not possible

[rugged topaz]

several servers pull this off. hypixel isn't one of a kind

and not every server uses some modified server jar

or they might, but it'd at least be public since not everyone has the money or expertise to do that

[granite stirrup]

its not possible

[rugged topaz]

you just said it's possible with a custom server

[granite stirrup]

i said might idk if it is or not

but im telling you u cant do it with nms or with just the spigot api

[rugged topaz]

well someone in this discord's gotta have the answer ig

[granite stirrup]

if this was possible it would be in the citizens config

to disable health above name

[rugged topaz]

citizens faq does not provide info on how to fix the issue, rather to just disable it

[granite stirrup]

yeah cuz it isnt possible

[rugged topaz]

but they do say you're able to get in touch with the plugin dev for an alternative

nah

^^

[granite stirrup]

it isnt possible

with spigot

or nms

[rugged topaz]

i think ik

what hypixel and other servers do

[quaint mantle]

well hypixel probably fixes it by using internal plugins

[rugged topaz]

name of npc is invisible, idk how they pulled that off or what

but it's just it seems a hologram on top of the npc

[granite stirrup]

its not possible lol

[quaint mantle]

which wont randomly create stuff

[rugged topaz]

and hypixel prolly does the same

so on that note

is it possible to make the npc's nametags and stuff invisible?

[granite stirrup]

yeah

just name the npc &3

[rugged topaz]

great

[granite stirrup]

or whatever

any color code

without text

[rugged topaz]

to my knowledge that'll give u something like this

[granite stirrup]

should make the name invis

[rugged topaz]

i think i'll have to use an outside plugin for that like nonamenpc ig

seems like that plugin's only limited to 1.8.8 tho and no idea why

wdym

idk at all how protocol lib's used

what exactly do you mean by "custom names"

[granite stirrup]

try /npc name ? with nothing after it

[rugged topaz]

nah it'll just give me an argument error

[granite stirrup]

ah it said somewhere dev builds allow you to do it with nothing

[rugged topaz]

isn't that premium tho

[granite stirrup]

¯_(ツ)_/¯

[rugged topaz]

well okay

i think i got everything i need tbh and might just use that 1.8.8 plugin

[tidal ferry]

so im doing this plugin where like the last player alive wins and I want it to show a title saying victory on the last player alive can someone help me

[dusty estuary]

is it possible to use code to check if a certain gmail account (in config file) is subscribed to a youtube channel

so as to people subscribe to a youtube channel before using some plugins

[opal juniper]

I imagine that it is possible with some oauth stuff

But YouTube doesn’t publicly share emails thankfully

[dusty estuary]

i mean cuz i need to find a way to get large amount of sub outside of YouTube, or else I will never get 1000 sub

But i dont see a api for doing so.... time to really dig into docs

Or maybe buy subs and view hours myself

[quaint mantle]

You don’t even need protocol lib for that

You just inject into the netty pipeline, and check for entity use packet or whatever

[rugged topaz]

PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.REMOVE_PLAYER?

does sending that packet to the npcs work

or

idek

[granite stirrup]

isnt npcs just fake players

[rugged topaz]

mhm

[granite stirrup]

then if that thing works for players that it might work for npcs

[rugged topaz]

im struggling to figure out how to loop thru all the npcs

[granite stirrup]

citizens api?

[rugged topaz]

soo we'll see in like a few years

yea trying

i'm not really sure what to do about this line

        Iterable<NPCRegistry> reg = CitizensAPI.getNPCRegistries();
        for (NPCRegistry _reg : reg) {
            Iterable<NPC> npc = _reg.sorted();
            CraftPlayer _npc = (CraftPlayer) npc.iterator().next(); // since NPC's aren't craftplayers
            PacketPlayOutPlayerInfo pack = new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.REMOVE_PLAYER, _npc.getHandle());
            _npc.getHandle().playerConnection.sendPacket(pack);
        }

that's commented

[quaint mantle]

Citizens doesent handle all that for you?

[rugged topaz]

wdym?

best explanation i found on how to loop thru npcs

am i supposed to send this packet to players and not npcs?

since that sounds more logical and possible

[quaint mantle]

Why can’t you just call .destroy

[rugged topaz]

i'm not trying to delete the npc

[rugged topaz]

i'm still on this

[quaint mantle]

If you use scoreboard teams you can set name tag visibility

If you really want it blank

[rugged topaz]

yea i do

but are you sure that's possible

seems too good to be true rn

[quaint mantle]

Lol ofc it’s possible

[rugged topaz]

does it disable showhealth objective tho

[quaint mantle]

I’m pretty sure playerinfo packet just takes them off tab btw

[rugged topaz]

it should

well blame this guy for misleading me then

[quaint mantle]

Idk what citizens is using

I mean you can try it

Doubt it’ll work, I think “hypixel” did this lol

[rugged topaz]

u dont know hypixel?

[quaint mantle]

Ofc I do

[rugged topaz]

quoted it lol

[rugged topaz]

ill see and lyk

[quaint mantle]

Yea cause it’s weird that the guy was like I think hypixel used this

Like ok lol?

[rugged topaz]

LMAO

this it?

[quaint mantle]

Unless he knows there secrets 🧐

Yea I believe that’ll work

Idk what you gotta do after that tho.

Assign teams and stuff

[rugged topaz]

well idk how to assign the team to the npc

i guess i already got the iteration done

[eternal oxide]

NPCs are treated as players so you add them by name to Teams

[rugged topaz]

by name?

[eternal oxide]

other Entities you add via UUID.toString()

[rugged topaz]

as in

&e&lCLICK for their name?

lmao

do i add entry or addplayer

[quaint mantle]

team.add(name)

[eternal oxide]

deprecated

[rugged topaz]

alright

[eternal oxide]

do as Bomp said, add them by name

[rugged topaz]

team.addEntry(replaceChatColors("&e&lCLICK"));
yea and that should be this?

that all?

already registered team, blah, set the scoreboard

that did it <3

thank u

[quaint mantle]

Bettt yw

                    }
                }
            }






        }

    }

im trying to make a block but when its placed it destroys a chunk
im not sure if this code is correct

[granite stirrup]

https://tryitands.ee

[cedar rampart]

oh lol it works

[subtle kite]

wait

[cedar rampart]

my server is just slow

[subtle kite]

oh does it break bedrock though?

[cedar rampart]

ye

[subtle kite]

thought so

something to think about if you want to use it your servers.

[granite stirrup]

Shouldn't he run in the bukkit scheduler?

So then it doesn't cause huge lag

[cedar rampart]

imma try and change it then

[red fox]

Good afternoon, could anyone give a link to the simple murder mistery/skywars/bedwars github?

At the moment I am trying to write my own mini-game and would like to see some sample code on how to correctly build the architecture of the application.

Thank's.

[next stratus]

Afternoon? It's 9am 🤨

[red fox]

Sorry, I was counting by my time zone 😢

[next stratus]

Ah my bad, sorry was a bit confused that's all

[stiff topaz]

Use ASkyBlock it’s a really great plug-in that I have used

BentoBox is a gamemode with a bunch of stuff like bedwars and one block

A bit like a mini game api for devs

It’s all open source too

So you can “borrow” code

[stable plinth]

hey guys, is it not possible to set default name to a custom item? I'm trying to set a smithing recipe for a custom item but the display name and attack damage won't change (cuz smithing will keep the item meta i guess)

[stiff topaz]

When a somebody uses a smithing table just change the item meta

[stable plinth]

so I should use prepareSmithingEvent right?

[stiff topaz]

Ill check

[stable plinth]

or SmithItemEvent

[stiff topaz]

Prepare just triggers when somebody puts an item in a smithing table

Not uses it

So SmithItemEvent is when a user completes an action

For the events read the spigot docs

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/SmithItemEvent.html

[stable plinth]

oh so SmithItemEvent is called when the upgraded item shows up?

[stiff topaz]

When they take the item

Called when the recipe of an Item is completed inside a smithing table.

[stable plinth]

ummm cuz I want to chanage the item meta after the upgraded item shows up (for preview purpose)

[stiff topaz]

It might be when a preview is made, I dont quite understand the docs

Its worth trying

[stable plinth]

oh setResult in prepareEvent will help i guess

[stiff topaz]

Try using SmithItemEvent

[stable plinth]

same here 😂

alright thx ❤️

[stable plinth]

it's onClickEvent, called after the player took the item

so it's gonna be prepare one

[stiff topaz]

Alright

[supple elk]

I'm trying to make a custom tab menu, however I've ran into some difficulty. This will currently add a fake player to every player's tab menu, however I don't know how to reset the tab menu. What I want to do is reset, then reconstruct the tab menu every couple of ticks but I don't know how I can do this/

[grand coral]

How to order a MySQL table to top 5 players by balance?
SELECT * FROM tablename LIMIT 3 ORDER BY Balance LIMIT 3?

[supple elk]

if you want top 5 why are you limiting to 3?

also don't you need to specify if it's ASC/DESC?

[quaint mantle]

ima assume they googled it

[quaint mantle]

remove the first LIMIT 3

[grand coral]

Me and MySQL are not the friends I want It DESC but must I add something for that?

[grand coral]

Thx

[supple elk]

I think you do ORDER BY Balance DESC LIMIT 3?

@grand coral

I don't know if the syntax is different for MySQL

[grand coral]

Ok thx

[eternal oxide]

DIAMOND is not a valid ItemStack

[earnest sonnet]

Αn itemstack

[eternal oxide]

a serialized ItemStack

[earnest sonnet]

Just save one and check it out

[eternal oxide]

getConfig().set("items.0", new ItemStack(Material.DIAMOND));

[supple elk]

anyone know about this?

[earnest sonnet]

Update it again

[subtle kite]

player.getPlayer().hidePlayer();

what is the hideplayer part I can't find it on the API website

[supple elk]

doesn't reset it

the packet just adds a player

[hardy swan]

just to confirm

comparing 2 UUIDs with .equals() yields the same result as comparing its .toString().equals() right?

[eternal oxide]

yes

[hardy swan]

ok great

[supple elk]

I want to make a team system for some minigames

there's the default mc Teams, however I want to keep track of some additional stuff

so I thought I'd extend Team, went down a rabbit whole of finding out where that actually led and eventually found the CraftTeam class which is private so I can't extend it

so do I just make a wrapper? That's kind of annoying tho

can I just implement Team, or does that break stuff?

[tardy delta]

why does this not works this time???

[lament bronze]

I don't see why you wouldn't be able

I extended Command and implemented PluginIdentifiableCommand once

[waxen barn]

what is the easiest way how to remove /pluginname:command form tabcomplete and only leave the /command?

[lament bronze]

just start typing the command

[tardy delta]

???

[lament bronze]

you can't really get rid of it

[tardy delta]

there's no way to do that

[lament bronze]

well you could but why

its made like that so if there are multiple commands with the same name you can use all of them

[waxen barn]

i can, either by editing the command dispatcher, or by removing it via the send command event, but idk if there is some easy way

[lament bronze]

or you could just remove the commands from the commandmap

you'd need to use reflection to access the command hashmap though

since it's a protected field

[waxen barn]

i made all plugins myself, so there are no conflicts between command names and it simply looks better without the plugin name in front of it

[lament bronze]

hm

lemme make a little method

[supple elk]

default implementation has all this kind of stuff in it

I don't know what it does but it's probably important, so it's probably safer to just wrap

[lament bronze]

yeah i guess

@waxen barn

    @SuppressWarnings("unchecked")
    public static void unregisterPrefixes(String prefix) {
        try {
            final Field f = Bukkit.getPluginManager().getClass().getDeclaredField("commandMap");
            f.setAccessible(true);
            final SimpleCommandMap commandMap = (SimpleCommandMap) f.get(Bukkit.getPluginManager());

            final Field knownCmds = SimpleCommandMap.class.getDeclaredField("knownCommands");
            knownCmds.setAccessible(true);

            final HashMap<String, Command> knownCommands = (HashMap<String, Command>) knownCmds.get(commandMap);

            for(Map.Entry<String, Command> commandEntry : knownCommands.entrySet()) {
                if(commandEntry.getKey().startsWith(prefix)) {
                    knownCommands.remove(commandEntry.getKey());
                }
            }
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }

look so

this is not the best way

since im doing a for loop and removing from the map at the same time

i'm sure you can do that part better

[waxen barn]

oh, thanks

[lament bronze]

but I think you get the idea

what spigot version are you running?

[waxen barn]

1.15.2

[lament bronze]

if you aren't running this onEnable then you need to sync commands

otherwise it's fine

[tardy delta]

can i copy the itemmeta of an item or something?

private void completeTrade(Player sender, Player target) {
        List<ItemStack> targetItems = new ArrayList<>();
        for (ItemStack s : target.getInventory().getContents()) {
            if (s.hasItemMeta()) {
                // copy itemmeta
            }
        }
    }

[quiet ice]

s.getMetadata() already results in a clone

[true jacinth]

Do I have to create a "plugin.yml" for every plugin I have? Or can I use my project to create multiple plugins using only one?

[waxen barn]

@lament bronze, it doesn't work, probably because as I saied, the hash map is responsible for executing the commands, but the tab list is managed by the command dispatcher, but still I can apply similar logic there.

[wintry marten]

For every plugin you create, there must be a plugin.yml

[true jacinth]

Jesus this looks like a mess

[quiet ice]

well, for every plugin jar - if you bundle plugins into a single jar it isn't needed

[lament bronze]

then you'd have to sync the commands

the command appears but it says it doesn't exist when you execute it right?

[true jacinth]

yeah i want to do this

[quiet ice]

But bundling plugins into a single jar is untypical to say the least at it would result in more work

So, don't try it

[ivory sleet]

I mean is creating a plugin.yml really that hard?

[supple elk]

how can I find players who have a particular skin? I'm trying to find players who just have a single colour on their entire skin

[quiet ice]

have a single class that extends JavaPlugin and the rest are just semi-independent subcomponents of it

[supple elk]

like the skins used in this tab menu

[true jacinth]

I know it takes only 30 seconds to do it, but if something is taking me less than 2 minutes, why not compact or automate?

[quiet ice]

having multiple classes that extend JavaPlugin is possible, but ultimately not worth the effort

[ivory sleet]

Well you could use annotation processing

Idk if that simplifies the process

[true jacinth]

🤔 I'm gonna take a look, thanks

[ivory sleet]

but just because something takes less than 2 minutes doesn't mean you can or have the ability to always automate it

[wintry marten]

Hello guys how do you store the data of a sign? Like if there is a message written in an oak_sign

How will I save it in memory (if u get what I meant :<)

[true jacinth]

I was thinking to do like this

[ivory sleet]

anything particular?

[quiet ice]

so?

That is a fully valid plugin.yml - if the intentions behind it are also valid is another thing

[ivory sleet]

Isn't always saved into memory (the 4 lines and if its glowing or not)

[wintry marten]

Ohh I see

[true jacinth]

I'm creating a server so I wish I could make just 1 plugin.yml that starts from PluginHeart and go through the other plugins. Basically when the player send /help MCPlugins they get a list of all options they can use. Instead of just multiple projects with just one class/plugin

[ivory sleet]

I mean you could mess with classloaders such that one jar loads all the other jars of yours

Though Idk why you would want that

[quiet ice]

no, dont - not worth the effort

Messing with classloaders is a pain

[true jacinth]

just to organize things and give up spaghetti code

[ivory sleet]

This just sounds a little bit like a you problem, not to be rude or anything.

[quiet ice]

All JavaPlugin classes have to be loaded with the bukkit plugin loader - which complicates things

[true jacinth]

Don't worry, yeah, it is somehow annoying to have to create plugins.yml for every plugin I do, instead of just having one that manages every single one

[ivory sleet]

yeah well I thought of something like papi expansions

[supple elk]

ok nvm I've found what I was looking for: https://freshcoal.com/maincollection

[quiet ice]

The issue is that we have no idea what they are actually doing

[river spear]

How can I prevent a door from opening and closing during the PlayerInteractEvent when it is canceled. Would you have to somehow block with client packets, but how?

[wary harness]

@river spear best use protocol lib

It will be the simpler way

[eternal oxide]

or just get the open state in the event and set it back to that after canceling

[wary harness]

@eternal oxide didn't know u can do that xd

[eternal oxide]

Canceling door open events is an odd one as even canceling the event can end up ignored by the client, so it ends up open.

[waxen barn]

yes

[lament bronze]

ah so you need to sync commands

here

    public static void syncCommands() {
        try {
            Method m = Bukkit.getServer().getClass().getDeclaredMethod("syncCommands");
            m.invoke(Bukkit.getServer());
        } catch (NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
            e.printStackTrace();
        }
    }

run this after you remove the commands

[waxen barn]

oh, ok

[waxen barn]

you forgot m.setAccessible(true); but ye, its working

[lament bronze]

is it rly needed

its public void

[waxen barn]

yep, it throwed illegalaccessexception without it

[lament bronze]

huh weird

[wary harness]

@waxen barn so what are u doing here

[waxen barn]

rn nothing, because @lament bronze solved the problem

[wary harness]

@waxen barn i mean what were u trying to accomplish 🤔

[waxen barn]

I was trying to remove the /plugin:command and only keep the /command form of command

[wary harness]

Oh

Lol

Why is that

[lament bronze]

.

[waxen barn]

bec I have tab complete on and it looks nicer without the plugin name

[wary harness]

Well I got you man

Perfection fetishism

😁

@waxen barn

[supple elk]

This is a command to give a blue head, how can I find the username or UUID of the player with this head?/give @p minecraft:player_head{display:{Name:"{\"text\":\"Dark blue (#00008B)\"}"},SkullOwner:{Id:[I;1390846929,-1328133163,-1764951099,406210083],Properties:{textures:[{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNmE0NjA1MzAxMmM2OGYyODlhYmNmYjE3YWI4MDQyZDVhZmJhOTVkY2FhOTljOTljMWUwMzYwODg2ZDM1In19fQ=="}]}}} 1

or does a player with this skull even exist?

[waxen barn]

I think, that you must loop all players and check if they have this skull in inventory.

[eternal oxide]

try assembling the ID

UUID = new UUID (long mostSigBits, long leastSigBits);

[river spear]

But what is the name of the packet that has to be intercepted?

[wary harness]

@river spear just cancel event and set state of doors back to closed like @eternal oxide said

[river spear]

That was my first thought too, but it didn't work out.

[wary harness]

Delay it for one thick

[eternal oxide]

how did you set the door open state?

[wary harness]

@eternal oxide it ould be he needs to delay task for one thick

[eternal oxide]

yes

he also likely needs to get the other half of the door and do the same

how to replace the item that is holding by the cursor on InventoryClickEvent event
I tried...

public void onInventoryClickEvent(InventoryClickEvent event) {

        Player player = (Player) event.getWhoClicked();
        ItemStack ClickedItem = event.getCurrentItem();
        ClickedItem.removeEnchantment(Enchantment.MENDING);
        
        //I TRIED THESE THINGS:
        //event.setCurrentItem(ClickedItem);
        //event.setCursor( ClickedItem );
        //player.setItemOnCursor(ClickedItem);

        //player.updateInventory();
    }

I'm just removing the clicked item's mending enchantment and replacing that item stack back to the player's cursor.

[river spear]

                                 TrapDoor door = (TrapDoor) bdata;
                                 door.setOpen(door.isOpen());
                                Bukkit.getScheduler().runTask(Main.main, () -> {

                                });``` no working

[eternal night]

I mean

you aren't delaying it 😂

[wary harness]

Delay one thick

@river spear

[kind coral]

what is the best way i can make an abstract class / interface for Kits that my Kit Class will extend/implement

Like Archer Kit extends/implements KitBase

something like that

[river spear]

what do you mean

[wary harness]

@river spear delayed tak runnable

[eternal night]

https://papermc.io/javadocs/paper/1.17/org/bukkit/scheduler/BukkitScheduler.html#runTaskLater(org.bukkit.plugin.Plugin,java.util.function.Consumer,long)

[wary harness]

@eternal night thanks god u send it

https://tenor.com/view/divine-mercy-jesus-god-bless-gif-5043304

[young knoll]

I mean that is delayed one tick already

[north niche]

Bukkit.getScheduler().runTaskLater(this,  () -> {
  //your code inside
}, 1);

it will delay 1 tick

[young knoll]

runTask schedules it for the next tick

[wary harness]

@north niche u maybe need to cancel event

And set item after it

[north niche]

i used runtasklater so we no need to cancel that i think so

[wary harness]

@north niche well not sure then

[river spear]

                                 TrapDoor door = (TrapDoor) bdata;
                                 door.setOpen(door.isOpen());

                                    event.getClickedBlock().setBlockData(door);
                                }, 1);```The trap door is still opened and closed briefly

[north niche]

any idea about this ?

[wary harness]

@north niche well i was talking about that

That u should cancel event

Then change items

[north niche]

can u send a snippet of it

[wary harness]

What is currently a problem

[eternal oxide]

you cancel the event, then set its state in teh delayed task, not the other way around

[north niche]

i just need to replace a itemstack that is holding by the player in his cursor
on "InventoryClickEvent event "

[river spear]

                                Bukkit.getScheduler().runTaskLater(Main.main,  () -> {

                                }, 1);```Still no change

[north niche]

can u explain me short what you are trying to do

[wary harness]

Door.isopen

[noble spire]

With plugin yml aliases for commands, if you use an alias does it automatically change the command name supplied to the plugin?

[wary harness]

Replace it with false

@river spear

[eternal oxide]

No. Cancel the event as normal. You will not be able to access the event inside your runnable as it will be finished. Create a final field for teh data you are going to set and teh block, so they can be accessed in the task

[quaint mantle]

is there any library that contains blocks and items from like 1.7 to 1.17so they are easilly accessible? like getBlock(WHAT, version)

[opal juniper]

What?

[supple elk]

the uuid is this: "52e6a3d1-b0d6-4bd5-96cc-fbc518364623", looking at this website: https://minecraft-heads.com/custom-heads/miscellaneous/6251-dark-blue-00008b

[opal juniper]

Not really sure what u mean

[supple elk]

however this is too short I'm pretty sure

https://mcuuid.net/

typing it in on that website gives nothing

[opal juniper]

whatcha doing?

oh - i read up

[quaint mantle]

there are changes for items and blocks with versions, like its called another in 1.13 and another in 1.8, most of the things, so is there any library that maps it all

[opal juniper]

idk

[supple elk]

my UUID is "675242d1-5461-4c6f-8017-8353046a44d8"

[supple elk]

I'm trying to do tab menu stuff

[eternal oxide]

You asked if the player existed. So I said assemble the UUID, from that you can see if the player exists

[supple elk]

well clearly the player doesn't exist, so how do I create a fake player with this ksin?

I'm trying to do this

when I create a game profile the skin is set to the plyaer or whichever UUID I pass in

hey i found this! this was my mistake i was checking this in creative all the time so only it not worked!

[waxen plaza]

Is there a special folder to store plugin data such as databases or config files?

[river spear]

It still doesn't work that it doesn't open and close

[cold field]

Guys, I was thinking... Is it a good idea make an updater that is able to update even the plugin dependency... Bc I've some dependency like the commandManager or the GUIFramework that I use and whenever I change something into the dependency I need to update every plugin... Obv this has the problem that if i remove some methods that my plugins use it will not work anymore.. What I am asking is, Is it worth?

[north niche]

ok what you need to do ? it should need to close automatically after few seconds ?

[river spear]

I don't want the client to see it open

I want the trap door to stay closed in the video I can see that it is open but it is already canceled.

[opal juniper]

u need to stop packets then

[river spear]

I want to try that too, but what is the name of this packet

[opal juniper]

check the wiki ig

[river spear]

is blockchange right?

[north niche]

https://www.spigotmc.org/resources/fakeblock.12830/
FakeBlock

This versatile plugin allows you to create fake blocks that exist for some players and do not exist for others!

These fake blocks are indistinguishable from real blocks and prevent players from walking through them, or interacting with them.

what does not work

[river spear]

the door was opened

[noble spire]

Is there an EntityMoveByEntity event?

(well something like that)

[wraith rapids]

there may be a collision event

[noble spire]

I can't find anything looking under org.bukkit.event.entity or org.bukkit.event.player

[eternal oxide]

I don;t belive there is

Some vehicle collisions is all

hmm oh well

[twin venture]

i need help iam trying remove items when player die , only the items with [Kit Lore]

but its not remove them ..

idk what's wrong there ar eno errors in the console

[wary harness]

@twin venture use delayes task after respown

[twin venture]

this is in playerDeathEvent ..

i really need help i was trying to figure this out for like 5 hours now ..

[wary harness]

Set it null

[twin venture]

that won't work

[opal juniper]

I would use pdc rather than lore

[wary harness]

Well then iterate thru slots

[twin venture]

what do you mean?

[wary harness]

And just set specific slot item null

What is pdc@opal juniper

[twin venture]

no no that won't work for me ..

i just want when player die

[dusk flicker]

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[twin venture]

iam using 1.8.8 ..

that wont work ..

:L

[wary harness]

@twin venture just iterate per slot

[twin venture]

and after i do that?

should i check for lore or ?

[wary harness]

And set item to null

[wraith rapids]

easy solution

don't use 1.8

[wary harness]

Check for lore

[twin venture]

best answer ..

[wary harness]

@wraith rapids i mean he will inconter same shit

On 1.17

[twin venture]

1.8.8 is the lagless ver i ever used

try to change my mind .

[wary harness]

Dont set item material to null

[twin venture]

you just told me too

lol

[wary harness]

Just set that specific slot item to null

So invenory.setitem null

[wary harness]

I told u to iterate thru inventory per slot

[twin venture]

ok

[wary harness]

And then u grab current slot number set it null and done

[twin venture]

still learning don't be mad bro .

[wary harness]

It is ok np

What's the best way to store a player's Location as a primitive type? My first thought is an int[] with {x, y, z}, but that misses out world, and looking direction. I could have multiple primitive vars where one is {x, y, z}, then {pitch, roll, yaw}, then ẁorld_index but there might be a better way...

[eternal oxide]

Store where?

[noble spire]

A player's PersistentDataHolder

|| https://hub.spigotmc.org/javadocs/spigot/org/bukkit/persistence/PersistentDataContainer.html ||

[eternal oxide]

odd, but why store a location in PDC?

?paste

[undone axle]

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

[eternal oxide]

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

Location in PDC

[noble spire]

You've probably seen the /spectator mode thing for smp before, where running the command toggles you between spectator and survival, but going into survival puts you back where you went in to spectator, so you can't use it for teleport as such, I'm making a simple implementation of that, except you need to store the last location persistently

thanks!

I didn't quite get my head around the to primitive and from primitive

[wary harness]

@eternal oxide so what is presistent data container

What is the point of it

[wraith rapids]

a container that persists data

[noble spire]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[eternal oxide]

Stores data on an object that is saved with the object

[wraith rapids]

for example, a custom ID on an itemstack that lets you identify it as a custom item easily

without having to check for visible and modifiable things like lore or name

[wary harness]

@wraith rapids intresting

So that saves on preformance

[wraith rapids]

and allows items to be renamed and their lore modified

[wary harness]

Is it supported on 1.8

[wraith rapids]

obviously not

[eternal oxide]

no

[wraith rapids]

nothing is supported on 1.8

[wary harness]

Oh ok

Just checking

Because people expect when they buy plugins support for 1.8

[wraith rapids]

tell those people to piss off

[wary harness]

Well those are bed reviews

Which I love to avoid

[wraith rapids]

tell choco to delete them

[wary harness]

@wraith rapids is that possible

[wraith rapids]

of course

[wary harness]

If some one review base on version

[wraith rapids]

if its a dumb or false review you can yeet it

reviewing something poorly because it doesn't work on a version it's not intended for is a false review

[wary harness]

Didn't know that and 1.8 and older version are making my plugin big and problematic

[eternal oxide]

just drop 1.8. If they want 1.8 they use older versions.

[wary harness]

@eternal oxide should peoe drop 1.12 to

?

What is opinion of community on that

[eternal oxide]

Thats a choice you need to make

Many willingly support 1.12+ A lot only 1.14+

[quiet ice]

Supporting 1.12 or older means that you cannot make any use of the wonders of newer java versions - which is another thing to consider

[noble spire]

Wait, what are you supposed to pass as a type for the second argument of PersistentDatContainer#set - PersistentDataType<T,​Z> type?

I was thinking PersistentDataType_LOCATION.class or something, although that doesn't work

[eternal oxide]

if you are using the class I just gave you, you pass it

[noble spire]

intellij doesn't like it

[wraith rapids]

if it wanted a .class, the method declaration would say it wanted a Class<PersistentDataType<T,​Z>>

[quiet ice]

IJ or javac?

[noble spire]

yeah

(IJ)

[wraith rapids]

yeah, you are trying to provide it a Class

it doesn't want a class

it wants a PersistentDataType object

[eternal oxide]

yeah, no .class ^

[noble spire]

yeah, I'm not sure what to pass 😳

[wraith rapids]

you pass it an instance of the class

not the class itself

[noble spire]

okay I'm dumb

thanks

I swear it didn't work hmmm

[eternal oxide]

Don;t worry, when I came back to Bukkit a couple of years ago I fell over that too

[wraith rapids]

i remember that

in fact I think I was the one who explained it to you

[ivory sleet]

Look how the PersistentDataType is implemented in the interface itself

[wraith rapids]

on the paper discord I think

[eternal oxide]

I could not for the life of me see what I was doing wrong.

[wraith rapids]

it was quite amusing

[eternal oxide]

Yep, it was on paper and NNY was my saving Angel

[noble spire]

no the thing is, I swear I tried that, and it just didn't work, hmmm

I have no idea what I did lol

[ivory sleet]

No because you did it wrong

[wraith rapids]

everybody else was telling you to learn java

[eternal oxide]

Yeps

[main dew]

How I can apply change without send packet to players? java Sign sign = (Sign) new Location(Utils.world, x, 23, z).getBlock().getState(); sign.setLine(2,"");

[wraith rapids]

you drop the packet with protocollib or you use nms to skip the doodads that send the packet

[twin venture]

so i found this code in the fourm .. its working for me thx for the guy who make it

it fixed my problem ..

but my other problem is not fixed

i gived my self diamond

and when i died well diamond is stuck with me

..

well i guess i need to get the last location of player before respawn?

how to make game?

[wraith rapids]

a fucking brilliant question

[idle grotto]

What game?

[wraith rapids]

you shoot it dead and you've got game

[wary harness]

@wraith rapids so was looking in to pdc

Will this not be more complicated or intense on system then just using nbtapi

ItemStack itemStack = ...;
NamespacedKey key = new NamespacedKey(pluginInstance, "our-custom-key");
ItemMeta itemMeta = itemStack.getItemMeta();
PersistentDataContainer container = itemMeta.getPersistentDataContainer();

if(container.has(key , PersistentDataType.DOUBLE)) {
    double foundValue = container.get(key, PersistentDataType.DOUBLE);
}

[eternal oxide]

no

[wary harness]

@eternal oxide u sure

[eternal oxide]

PDC is a wrapper over NBT

[wary harness]

I mean I understand that

But nbtapi look simpler

[eternal oxide]

its doing the exact same thing as NBTAPI

[ivory sleet]

What’s simpler?

Or what looks simpler?

[wary harness]

@ivory sleet nbtapi then pdc

[ivory sleet]

I asked what is simpler. Not which one.

[wary harness]

Loom example up from tutoril

In chat

Pdc needs more lines of code then nbtapi

[ivory sleet]

Myeah in that sense I guess

[wary harness]

Like here u need instance of plugin to get namespacekey

And so on

So I dont know which will be more intense on plugin

[eternal oxide]

neither

Both will perform the same

[wary harness]

Example nbtapi can do lag if u are checking nbt data on pickupevent

And there is lots of items

Expirianced it

Learned on hard way xd

[kind coral]

hi guys i am making a kitpvp plugin for my server, tho i have like 20kits or something, and i want to "register" them efficiently, how would i do this, i got an abstract class ( i know i can make it an interface but i tought i could add something in it)

as u can see many lines in the archer class are taken by getting itemstacks

[ivory sleet]

For the registration, maybe have some sort of immutable registry and then have a builder, each entry would take 1-2 lines.

[kind coral]

yeah, as of registering i know how i could make, the only thing is how i would actually make the kit class compact

[wraith rapids]

wither skull is its own block these days i'm pretty sure

[vale cradle]

Cuz MrTommy was taken lol

[vale cradle]

If you're going to make all methods abstract, you'd rather use an interface for it lmao

[kind coral]

thats what i said, its because i think i will place a full body method there

thats why i made it abstract

[vale cradle]

Btw, there are so many methods that are not actually needed to be abstract. You can simply make a super class wich requires a list of the items and the permission needed for this kit, that way you can define the kits and not even need to make a subclass extending from Kit

[kind coral]

yeah i know, but i feel better using interfaces and abstract classes

[vale cradle]

Smth like:

public class Kit {
  private List<ItemStack> items;
  private String permission;
  public Kit(List<ItemStack> items, String permission) {
    this.items = items;
    this.permission = permission;
  }
  
  //Just make the getters
}

[vale cradle]

Well, it's not

as you see, you're complicating so much trying to make it that way ;p

[lament bronze]

could use an enum for kit types

or even just a string for the name

[kind coral]

the only thing, if i make an itemstack of potions with amount for example 27 and i give them to the player, will they stack or not?

also, what is the sound that the arrow makes when hitting the player?

https://youtu.be/QWhfpniYV3w this one

[ivory sleet]

They will stack

[kind coral]

sad

[ivory sleet]

mye

[vale cradle]

Just add each one individually

[opal juniper]

For loop go brrrrrr

[kind coral]

if you know

[kind coral]

still, linkedlist would be used

[ivory sleet]

ArrayList iterates faster probably tho

[vale cradle]

Copy this, I think this might be helpful:

public void addVanilla(Player target, ItemStack item) {
  int iterations = item.getAmount() / item.getMaxStackSize();
  int toGive = item.getAmount();
  for (int i = 0; i < iterations; i++) {
    int give = toGive % item.getMaxStackSize();
    toGive =- give;
    ItemStack itemToGive = item.clone();
    itemToGive.setAmount(give);
    target.getInventory().addItem(itemToGive);
  }
}

[ivory sleet]

Or just an array

[vale cradle]

@kind coral, you might want to take a look to this snippet

[hardy swan]

I'm very curious if we have a class that extends ItemStack, say PaperClone that is basically of material paper, without extra stuff like display name or custom model

Can the server recognize that the item is an instanceof PaperClone?

[eternal oxide]

an object on the server, yes. An ItemStack sent from the client, no.

[hardy swan]

But you can mix this paper with other normal paper, no?

[ivory sleet]

I mean ItemStack is just an api class essentially

Extending it will have minimal impact though as it for instance gets cloned to a CraftItemStack or the nms variant depending what you do with it

[vale cradle]

Only when in runtime, when the item gets serialized and retrieved back (e.g. Server Restart) server won't be able to recognize it anymore

[kind coral]

or i could just check if the itemstack is a potion and do a for loop

or just check if the itemstack is above max stack size

[ivory sleet]

Oh yeah that’s true unless you’d annotate it with the configuration serialization delegation annotation I think?

[vale cradle]

Method is meant to work globaly for any item you want

Not only potions

[kind coral]

i just need potions so yeahh

[vale cradle]

that's exactly what the method does

lol

[kind coral]

anyone knows btw?

[kind coral]

yeah

[ivory sleet]

Check Javadoc

[kind coral]

i can't find it

i saw arrow hit player and arrow hit

they do not match

[vale cradle]

Oh, yes, you can override that ;0

How I've been so stupid this time

[ivory sleet]

I found out about it recently also 😅

[hardy swan]

Ohhhhh

Right

[vale cradle]

More practical than make it a mixin using a custom Java Agent kek

[ivory sleet]

🥲

[wraith rapids]

the underlying server itself doesn't handle ItemStacks at all

ItemStack is a bukkit api concept

every time you pass an ItemStack to the server, for example by placing it in an inventory, the values of the ItemStack are retrieved with the various getters and a new nms itemstack is built from them

[hardy swan]

yea that makes sense

[vale cradle]

kinda, but you can override those getters to make that items custom ;p

[wraith rapids]

well yes, but only within the scope of those getters

[vale cradle]

Like a getLore, you can, for example, make the lore prettier using a better design for enchantment definitions

just to give you an example

[wraith rapids]

and when you retrieve it back from the inventory or wherever you placed it, you will just get a new standard CraftItemStack instead of your custom class

you can do it, but you need to remember that the moment you pass your item to the server it drops everything except what an itemstack might be expected to hold

[vale cradle]

Basically ^^

[amber hill]

there is some issue with my mob spawning in my world .I don't know why the chest become invisible but I can open them

[opal juniper]

They seem completely unrelated…?

[vale cradle]

mob spawning? chest invisible?

[wraith rapids]

sounds like a 1.8 user

[opal juniper]

TRUE

[hardy swan]

i was wondering about this cuz we discussed about testing if an inventoryholder is an instanceof a custom class that implements inventoryholder

which I also find weird that it is possible

that every of this instance in saved in metadata space?

[ivory sleet]

ItemStacks get cloned like whenever u pass them through other api classes

InventoHolder is quite different sometimes

[vale cradle]

Bukkit is stupid when it comes to implement your own version of their api stuff lol

keep that in mind

[wraith rapids]

inventoryholder can hold classes provided by plugins as it is not persistent

[ivory sleet]

Yeah it misses @NonExtendable 😫

[wraith rapids]

it only exists as long as the inventory itself is around

i'm not sure if it is evicted properly on plugin unload

probably not

[vale cradle]

Reload the inventory holder somehow (Reloading a chunk if its a Chest or Player Rejoin if it's a player) and will most likely go brrrrrrrr

[kind coral]

i still can't find it, anyone knows?

[hardy swan]

Sound.ENTITY_ARROW_HIT_PLAYER?

[wraith rapids]

and that's why you need to provide a PersistentDataType both when setting and getting from a PDC

[kind coral]

its different

[wraith rapids]

neither the complex object nor the data type object are stored anywhere at all

only the primitive data the datatype's serializer shits out is stored

[ivory sleet]

Probably just different yaw and pitch

[vale cradle]

so, sounds have yaw? kekkkkk

[vale cradle]

You can always serialize a Function (don't.)

[ivory sleet]

Yeah I believe lol

[kind coral]

nop, i've tried everything ahah

[ivory sleet]

Assumably not

[vale cradle]

naw, they don't

[vale cradle]

probably client sided

[wraith rapids]

even if you do try to serialize the function, the function object itself is not retained anywhere

[vale cradle]

ofc

that's the purpose of serialization

[hardy swan]

maybe Sound.ENTITY_ARROW_HIT?

[ivory sleet]

Oh nvm volume 🥴

[kind coral]

nop

[hardy swan]

prob client side then, only heard by the shooter

[kind coral]

bruh

[ivory sleet]

Spleed anyways

If you mean the hypixel sound, they use exp orb one

[hardy swan]

or player level up one

[ivory sleet]

But what solarrabbit mentioned is correct for vanilla

[kind coral]

nono i mean the minecraft one, btw i fixed it i made a for loop that plays each pitch from 0 to like 2 and it was 0.5 thx 😄 i tried them all by hand but i think i missed 0.5

[ivory sleet]

👍

[loud island]

What's the best way to go about making a http request in a plugin?

[eternal oxide]

That all depends on what request you want to make and what to do with the response

[loud island]

POST request & the response is pretty much not needed (except status like 404)

[eternal oxide]

this is a simple request. just wrap it in an async task ```java
URL url = new URL("https://api.mojang.com/users/profiles/minecraft/" + name);

        URLConnection conn = url.openConnection();
        conn.setReadTimeout(5000);
        conn.addRequestProperty("User-Agent", "Mozilla/4.0");
        conn.setDoOutput(false);

        // Handle redirects.
        String redirect = conn.getHeaderField("Location");
        if (redirect != null){
            conn = new URL(redirect).openConnection();
        }```

as you don;t need to know what the response is

[loud island]

wouldn't that make a GET request?

[eternal oxide]

probably

just build yoru address as you need

[eternal night]

if only java 16 had an inbuild http client

[eternal oxide]

else, a very quick google returned https://stackoverflow.com/questions/3324717/sending-http-post-request-in-java

[loud island]

Perfect, thanks!

[eternal night]

or just use the http client xD https://openjdk.java.net/groups/net/httpclient/intro.html

might be the more elegant solution anyway

[minor garnet]

Does anyone have an idea to create a collision system that can rotate the item through the place it collided?
is hard to explain

[vale cradle]

this is minecraft dude, not a game engine

take it or leave it kek

[minor garnet]

your bastard, even if it's minecraft regardless or there are no ways to do this

[wraith rapids]

define 'item'

[minor garnet]

armor stand euler angle

[wraith rapids]

not via the api

api doesn't expose proper collision shapes

[minor garnet]

not like, I managed to do similar things by rotating the item across the face of the block

hm

[wraith rapids]

if you plug into nms for collision shapes or hardcode them yourself, yes

after that it's just math

after that it's just math

[minor garnet]

like, i use a egg like projectile

[vale cradle]

I mean, he refered to rotate an entity through the place it collided

basically implement physics

[minor garnet]

I use the projectile to detect collisions, but the tricky thing would be to just rotate it according to the direction the projectile went, but there are certain times when it rotates the item gets into the block xd

[vale cradle]

that's the thing

I think there is no conventional way to do this

to not say there is no way to do this cuz I'm not totally sure tbh

[wraith rapids]

implementing physics is just math

and something that has been done a billion times, so a lot of helpful resources exist for it out there

[minor garnet]

i do not know how to do it

[wraith rapids]

look it up on stack overflow

[minor garnet]

i check

[wraith rapids]

check again

[minor garnet]

i'll check***

[wraith rapids]

but, again, you need access to collision shapes to rotate things properly

otherwise it'll phase into shit while you rotate it

[minor garnet]

i cant use the euler angle like a collision shape ?

[wraith rapids]

rotating a collision shape causes its points to move

if you rotate your item, you move the points of its collision shape

you need to be able to tell when those points collide with other collision shapes and stop rotating it accordingly

otherwise the corners of your item will phase into shit while rotating

well. unless your collision shape is a sphere

[dusty sphinx]

Is there a way to register/dispatch events? Not listeners, events.

[wraith rapids]

Bukkit.getPluginManager().callEvent(event)

[eternal oxide]

Yes, but you should only ever do it to offer other plugin the opportunity to prevent your actions

[dusty sphinx]

I want other plugins to be able to hook into my plugin

[wraith rapids]

for 'registration', your event class should declare a public static HandlerList getHandlerList() method which should return the class' HandlerList

f.e

public class TransactionEvent extends Event {

    private static final HandlerList handlers = new HandlerList();

    @Override public @NotNull HandlerList getHandlers() { return handlers; }
    public static @NotNull HandlerList getHandlerList() { return handlers; }

java can't enforce you to implement a static method, so the most common noob issue with custom events is forgetting about the static getHandlerList

[dusty sphinx]

so event is just an abstract class?

actually that doesnt matter

[wraith rapids]

yes, and all events must extend Event

org.bukkit.event.Event

[dusty sphinx]

is PluginManager.callEvent() blocking?

[eternal oxide]

yes

[dusty sphinx]

hmm ok

[eternal oxide]

It has to be so you can get teh canceled state when finished

[dusty sphinx]

cancelled state?

[eternal oxide]

If your event is cancelable .

[dusty sphinx]

ah

[eternal oxide]

it gets passed to any registered listeners, then you get it back to see if anyone made any changes

[dusty sphinx]

so

I would construct the event with whatever parameters that I want, and then call it, correct?

[eternal oxide]

yes

[dusty sphinx]

and listeners will receive the instance of the event

ok

i think i get it

[eternal oxide]

the return of callEvent gives you the result of your event

[wraith rapids]

its void

[eternal oxide]

ok yes

teh event is modified directly

[wraith rapids]

chaining .isCancelled on it would be too easy

[dusty sphinx]

should i call super() in my constructor

[wraith rapids]

super is called implicitly

Event has two constructors

the default no-args constructor

and a constructor intended for events that are supposed to be fired asynchronously

which lets you pass a boolean that determines whether the event is fired asynchronously or not

[dusty sphinx]

if it returns void how do I get the result

[wraith rapids]

you store the event in a variable

[eternal oxide]

the event you pased

[wraith rapids]

        PreTransactionEvent preEvent = new PreTransactionEvent(... );
        Bukkit.getPluginManager().callEvent(preEvent);
        if (preEvent.isCancelled()) { do stuff }

there is no explicit, separate result; the event instance itself is modified

[eternal oxide]

That event is not cacnelable

[wraith rapids]

yeah

you canc cacnel it

[dusty sphinx]

how do I listen to an event i dispatch

[wraith rapids]

as you would to any other event

[eternal oxide]

same as you would any event, import it in a Listener

[dusty sphinx]

how does bukkit know which listeners to fire when an event is dispatched, is it the name of the listener or something else

[wraith rapids]

with the HandlerList

as the name might imply, it's a list of event handlers

[dusty sphinx]

wrong question mb
how does bukkit know which event to register the listener to

is it the name of the listener or something else

[wraith rapids]

registerEvents scans the class of the object you pass it

and looks at the method declarations

[dusty sphinx]

ohhh so its the type of the argument

[wraith rapids]

yes

[dusty sphinx]

wow i was overthinking that

[hardy swan]

can I ask a ruby question here

[wraith rapids]

only if it's ruby on rails

[hardy swan]

# event.start_date = 2021-06-25T00:00:00.000Z
clone = event.clone
clone.attributes ={:start_date=>event.start_date.strftime("%d %B %Y")}
render json: {:start_date=>clone.start_date, # = '2021-06-25T00:00:00.000Z'
:intended_date=>event.start_date.strftime("%d %B %Y")} # = '25 June 2021'

ok it is, so basically

my clone's attributes never gets updated

any idea why

[wraith rapids]

no

[hardy swan]

ok maybe now clearer

[dusty sphinx]

does it go all the way up the hierarchy ladder? like if I dispatch an event that extends another event and there is a listener that listens to the base event will it get fired when the event that extends the base event is dispatched

woah boy thats some run-on sentence

[wraith rapids]

only events that have a static HandlerList in the class can be listened to

abstract superclasses like Event or PlayerEvent don't, so you can't listen to them

but yes, each superclass of an event declaring a HandlerList is invoked in order

for example, EntityDamageEvent and EntityDamageByEntity event both declare a HandlerList

firing the latter will first fire listeners for the latter, and then for the former

while firing the former only fires the listeners for the former

[dusty sphinx]

alright, makes sense

[dusty sphinx]

i see you used isCancelled, is that a method I have to implement myself or do I inherit from another class

[wraith rapids]

you'll have to implement it yourself if your class extends/implements Cancellable

but, it's just a boolean field with a setter + getter so not much to implement

[quaint mantle]

I was wondering if its possible to make a gui smaller than 8 slots?

like this

[chrome beacon]

That's a hopper

[quaint mantle]

Ahhh

[limpid bronze]

Hey, I have a question, according to this wiki https://www.spigotmc.org/wiki/creating-a-gui-inventory/ I should create a variable outside of the functions and then use that variable in the "event" function InventoryClickEvent to check if the inventory is the same. Is there any other alternative to not creating a variable outside of the functions or do I have to do like the wiki?

[wraith rapids]

super hyper technically yes there is an alternative but it's not one you should take

using fields is part of java; you should get used to it

[limpid bronze]

Ok so better to use the wiki technique

[olive scaffold]

Sorry, not really sure where to ask this - I have had multiple users show me that there is no option to pay for my premium plugin when they click the purchase button on the resource page, I have had people purchase it already (last one was on the 25th of June) but nothing has changed on my end and now it seems that the option isn't there for new purchases. Any ideas what could have caused it or where I should take this problem?

[wraith rapids]

simple solution

don't sell premium resources

you capitalist pig

[eternal oxide]

Come join us socialists. Give us everything and we'll look after it for you.

[earnest sonnet]

Yeeees

We're the most trustworthy batch

[waxen plaza]

How do I make it so when I type a command for example "/tp" and I go to type the next argument to show me a list of options like "/tp" does show a list of players

[earnest sonnet]

No clue xD try asking in the off topic/chat/help and try the irc, maybe they know there

[earnest sonnet]

Do you mean tab complete?

[waxen plaza]

Yes, that's what I mean

[earnest sonnet]

Aaaah, I'm not at the pc atm, but if I remember correctly you have to implement it and populate a list or something along those lines

[waxen plaza]

Do you know a tutorial or a post somewhere?

nvm, I found a tutorial when I searched tab complete

[wraith rapids]

implement tabexecutor and return a list of results

[waxen plaza]

thanks

[quaint mantle]

how to force entity to shake?

[wraith rapids]

a brilliant question

[sage swift]

type in chat "boo" while looking at it

[worn tundra]

works better if the entity doesn't see you

[quaint mantle]

ha-ha

[waxen plaza]

Why is the tab completer not working?

[chrome beacon]

Did you register the tab completer

[waxen plaza]

Yes, like this "getCommand("privateChest").setTabCompleter(new VaultTabCompleter());"

Do you know why it doesn't work?

[wraith rapids]

have you debugged it

[waxen plaza]

no

[wraith rapids]

try debugging it

[waxen plaza]

ok

btw I implement TabCompleter is that right?

[wraith rapids]

probably

a good first step is to have sysout in your onTabComplete to see if it's getting called at all

[waxen plaza]

It doesn't get called

[real spear]

how do i set a permission level for a command I am making?

Example: I want to req op or a custom permission to run a command.

[earnest sonnet]

plugin.yml

and if checks

[compact haven]

if (!sender.hasPermission("myperm")) return;
if (!sender.isOp()) return;

[waxen plaza]

Anyone knows why tab completer might not work?

[digital plinth]

bc you did something wrong

:>

post some code for debugging

[waxen plaza]

the method doesn't get called at all

and I did set tab completer on my command

[digital plinth]

codeeeeee

no code = i can only tell you you did something incorretly

[waxen plaza]

    public List<String> onTabComplete(CommandSender sender, Command command, String alias, String[] args) {
        if (!(sender instanceof Player)){
            Bukkit.getServer().getConsoleSender().sendMessage("Tab Completer non player");
            return null;}
        Bukkit.getServer().getConsoleSender().sendMessage("Tab Completer");
        List<String> arguments = new ArrayList<>();
        arguments.add("Argument1");
        arguments.add("Argument2");
        arguments.add("Argument3");


        return arguments;
    }```

getCommand("privateChest").setTabCompleter(new VaultCommand());

I watched a couple tutorials to figure what I did wrong but they did same thing as me

[digital plinth]

it seems fine to me hmmm
