atomic trail
#

Ok so yeah it’s not a plugin

#

Idk what I’m on about

dusty frost
#

oh?

atomic trail
#

It’s used in other plugins

#

To simplify stuff like handling configs etc

#

And chatutil and so on

dusty frost
#

That will be used as a separate jar in each thing?

#

Like, you'll put ValdemarF-Lib.jar or whatever in your Paper backend server and your Velocity server?

atomic trail
#

Not sure if all plugins using the library should shade it or have it at runtime

#

I think have it at runtime

#

Because multiple plugins on each backend server will probably use it

dusty frost
#

Plugins using the library, if the library is a .JAR file included in the plugins folder and loaded as a plugin by the classpath loader, should ABSOLUTELY NOT shade it

#

They should compileOnly it and use it at runtime

atomic trail
#

It won’t be a registered plugin though, that’s not the plan at least, it should work like Configurate basically, other than the fact that Configurate is in the server jar already

#

The default version of Configurate I mean

dusty frost
#

I meann you have to have it loaded by the Bukkit classloader somehow lol

atomic trail
#

Is Configurate also setup as a plugin?

dusty frost
#

No, because it's exported as a library by Paper

atomic trail
#

Ah yeah ofc

dusty frost
#

you don't include the Configurate .jar in your plugins folder lol

atomic trail
#

Yeye lol

#

So I should register the library as a plugin as well?

dusty frost
#

Yes, so that it can be loaded by the Bukkit classloader

#

And optionally like, do other stuff

#

like maybe if you want a global config for the library, or to have it register some listeners or common things

atomic trail
#

Alright yeah, that would make sense, but no server would have the common jar would it?

#

That would just be internal right?

dusty frost
#

uh, I'm not really sure?

#

it depends on what you're doing

#

In the scenario as I understand it, people using your plugins would need like SummitLibs-Bukkit.jar in their plugins folder, plus whatever plugins you make that depend on them

atomic trail
#

Yeah

#

Exactly

#

But not the common module I’d assume

dusty frost
#

ah I see your question now, yeah you'd only have the specific implementation jar in your plugins folder

atomic trail
#

Because it should be shaded in the bukkit module

dusty frost
#

but each specific implementations one would basically just include all the code of the common one

atomic trail
#

Yeah perfect

#

That makes the most sense yeah

#

Thank you for your help! :))

dusty frost
#

absolutely!

Hello there, I was wondering how I could update the victim's scoreboard inside the if (killer != null) in my onPlayerDeath script. I tried importing the code below into it but it won't work.

        int victimKillStreak = killStreaks.getOrDefault(victimId, 0);
        int limitedVictimKillStreak = Math.min(victimKillStreak, 5);
        ChatColor victimKillStreakColor = getColorForKillStreak(limitedVictimKillStreak);
        String coloredVictimKillStreak = victimKillStreakColor + String.valueOf(limitedVictimKillStreak);
        victim.setPlayerListName(victim.getName() + " " + victimKillStreakColor + "[" + coloredVictimKillStreak + "]" + ChatColor.RESET);
        updatePlayerScoreboard(victim);```


Full  onPlayerDeath script: https://pastebin.com/ZCfYshw8

guys how can i disable the plugin name like when i type/warp it says /warp:warp
how can i change whether it shows the name of the plugin or not

worn jasper
hazy vale
#

ofc

worn jasper
worn jasper
#

It's an intended feature. If 2 plugins have the same command, that can be used to differentiate between each other.

hazy vale
#

i know that but i dont need it

worn jasper
hazy vale
#

how do i do that?

worn jasper
# hazy vale how do i do that?

google is your friend, but in short, you would get all the completions, remove those you don't want and set the completer if I recall correctly.

lilac portal
#

Can someone help me with getting the minecraft server's ip address without port?

#

So like: 82.3.122.112

#

i need it for an api call

#

The reason why i can't use plugin.getServer().getIp() is because my server is on bungeecord, so i don't have the server-ip set in server.properties

dusky harness
lilac portal
#

in java

#

as a string

dusky harness
#

wdym dynamic?

lilac portal
#

numerical

dusky harness
#

it gets the public numerical ip

#

note that it should run async though

#

or actually even better - get it once and save it in onEnable, no async needed there

lilac portal
#

It works, tysm!

#

By the way, i have the public void inside the onEnable so that shouldn't cause any issues

somber gale
#

Not sure if my logic here is right...
I want to ensure, that the = found is after {{r and that the last } is after it...

        if(target.toLowerCase(Locale.ROOT).startsWith("{{r=") && target.toLowerCase(Locale.ROOT).endsWith("}}")){
            int start = target.indexOf('=');
            int end = target.lastIndexOf('}');
            
            if(start < 3){
                CachedWarnHelper.warn(expansion, "reg-start", raw, "Index of '=' for Regex is invalid. Needs to be at least 3, but got" + start + ".");
                return null;
            }
            
            if(end <= 3 || end < (start + 1)){
                CachedWarnHelper.warn(expansion, "reg-end", raw, "Invalid index of '}'. Expected at least 4, but got " + end + ".");
                return null;
            }
            
            Matcher matcher = Pattern.compile(target.substring(start + 1, end - 1)).matcher(text);
        }

Hello there, I was wondering how I could fix my onPlayerDeath javascript so that the correct killstreak is displayed over the players head. It keeps telling me there is an Invalid killstreak placeholder for the player but I don't know how to fix it. And my scoreboards aren't updating in real time. Here is my full code.

Why is wait (\d+) seconds not matching wait 5 seconds?

Matcher matcher = getMatcher(task);
int time = Integer.parseInt(matcher.group(1)); // this line
#

java.lang.IllegalStateException: No match found

#

what does getMatcher do?

warm steppe
# 
public Matcher getMatcher(String string) {
    return getPattern().matcher(string);

#

ok now a different question. How can i send a title to a player inside completablefuture#runasync

#

i did tru bukkitscheduler#runtask, but it didnt show the title

spiral prairie
#

Does it work without it?

warm steppe
#

no

spiral prairie
#

Well if it doesn't work within a runnable you can try with packets as a last resort but if that doesn't work your code ain't runnin

warm steppe
#

a nwm, it does work

#

i had the defautl task id as 1, but needed it to be 0

#

is there anyone actually willing to provide insight on my delima here someone helped me with making my first tab complete class for my pluggin and im trying to add more tab complete args to that command for instance right now its /command <tab completed> <arg> <arg> <arg string builder>
i want to add a tab complete list to the second and third <arg> but these ones would be manually set to static elements the first tab complete is made up of a list of config paths for the worldpoints that are in the config i tried to copy the public tabexecute but its giving me some error on not superclass or what have you so any insight on what i could do to achieve this would be great i even tried to reverse engineer the class to see where the tabex is called in the command etc but its not so im at a loss here and dont want to spend hours scraping through forums and jdocs to try to figure this out

this is the class code as of right now http://ycs.canvaswrite.com/resources/uploads/TabEx.java

merry knoll
fleet shale
#

already have that so this wasnt helpful 🙁

merry knoll
#

args - The arguments passed to the command, including final partial argument to be completed

#

just read

fleet shale
#

i do see my error was trying to make a second override but now i have a new issue the matterials list i need to display all and every poissible (including uncraftable) item in the game im only getting ACACIA_BUTTON since its the very first available item alphabetically and its the only tab complete option for all args now http://ycs.canvaswrite.com/resources/uploads/TabEx.java

merry knoll
#

turn all mats into a list then return that

fleet shale
#

i did attempt that but im pretty wure what i did was not right

merry knoll
#

Arrays.asList(Enum.values())

fleet shale
# 
String tabString2 = "";
        if (args.length > 1) {
            tabString2 = args[1];
        }
            for (Material items : Material.values()) {
                if(items.getKey().asString().toLowerCase().contains(tabString2.toLowerCase())) {
                    tabComplete.add(String.valueOf(items));
                }
            }
merry knoll
#

or you can just stream it

#

Stream.of(Enum.values()).map(Enum::name).collect(Collectors.toList());

#

either works

#

enum here would be material obviously

#

i would probably cache that list though rather than mapping it over and over on each tab complete request

fleet shale
#

ok that worked for the item list but im still only getting that list as tab complete instead of the pointnames for the first arg

# 
// Grab the current text the player is typing, or empty String if none
            String tabString = "";
            if (args.length > 0) {
                tabString = args[0];
            }
            // Go through each point and add values to our list if the player is typing them
            for (String pointName : points.getValues(false).keySet()) {
                if (pointName.toLowerCase().contains(tabString.toLowerCase())) {
                    tabComplete.add(pointName);
                }
            }
        String tabString2 = "";
        if (args.length > 1) {
            tabString2 = args[1];
        }
            for (String items : Stream.of(Material.values()).map(Material::name).collect(Collectors.toList())) {
                if(items.toLowerCase().contains(tabString2.toLowerCase())) {
                    tabComplete.add(String.valueOf(items));
                }
            }

            // Return our list
            return tabComplete;
    }
``` this is just a snippet of the full class so you can see what ive put in so far im sure its something silly and small that ive dine wrong here for the first args tab complete
#

im seeing now the whole list for the tab complete is every item ive added so far but how can i remove a certian section of added elements tot he array when its tab completing to the new arg

merry knoll
#

String tabString = "";
if (args.length > 0) {
tabString = args[0];
}
what is this even

#

args gives you whatever they entered already

#

so, check for size then for arguments themselves

#

its just what was in there from when the first tabexecuter was given to me so i coppied it assuming its required

What is the best way for saving an inventory to MySQL and then being able to loading it back in game

Every item to a json string then map by slot number (or include in json string).

Hello I was wondering how I would fix the errors in the lore in my script. It displays this error to me in console: "Tag not valid: {display:{Lore:['{"text":"","extra":["Re-roll your Boost to any random number between 1-5"]}'],Name:'{"text":"","extra":["Reroll Book"]}'}}"

    public void onPlayerUse(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        ItemStack item = event.getItem();

        // Check if the player is using a reroll book
        if (item != null && item.getType() == Material.KNOWLEDGE_BOOK) {
            ItemMeta meta = item.getItemMeta();
            if (meta.hasDisplayName() && meta.getDisplayName().equals("Reroll Book")) {
                // Create a list for the lore
                List<String> loreList = new ArrayList<>();
                loreList.add("Re-roll your Boost to any random number between 1-5");

                // Set the lore to the meta
                meta.setLore(loreList);

                // Set the meta to the item
                item.setItemMeta(meta);

                // Update the item in the player's hand
                player.getInventory().setItemInMainHand(item);

                // Remove the reroll book from the player's inventory
                item.setAmount(item.getAmount() - 1);

                // Create a new Random object
                Random rand = new Random();

                // Generate a random killstreak as soon as the reroll book is used
                int killStreak = rand.nextInt(5) + 1;```

@fading stag - Yeah, the repository is private but the gist I'm about to link you should do the job. If you're saving a non-player inventory, I linked you the method directly (named toBase64), otherwise search for the playerInventoryToBase64 method which is at the very top. https://gist.github.com/graywolf336/8153678#file-bukkitserialization-java-L63

Hello, I have 2 databases: gitea (as example) and luck perms database. The first one was created by its user itself but the second one was created by postgres user and later transferred to luck perms user, now it looks like this:

 gitea           | gitea           | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
 luckperms_proxy | luckperms_proxy | UTF8     | en_US.UTF-8 | en_US.UTF-8 | luckperms_proxy=CTc/luckperms_proxy

The problem is that if I remove all privileges at luck perms database from luck perms user then it gets unable to interact with that database from its user BUT gitea db hasn't any configured privileges and gitea is able to interact with its database

fleet shale
#

Omg and it wasn’t even the right repository anyway 🤦🏼‍♂️

molten venture
frozen fox
molten venture
# frozen fox Ofc I can but the question is still open: why can't the owner (even if it was re...

In PostgreSQL, the owner of a database does indeed have full privileges to interact with the database. However, these privileges apply to the database itself, not necessarily to all the objects within the database such as tables, views, sequences, etc.

When you reassigned the ownership of the luckperms_proxy database from the postgres user to the luckperms_proxy user, the luckperms_proxy user became the owner of the database, but not necessarily the owner of all the objects within the database. The ownership of these objects would still be with the original owner, i.e., the postgres user.

If you then removed all privileges from the luckperms_proxy user, it would lose its ability to interact with the objects within the luckperms_proxy database, even though it is the owner of the database.

To allow the luckperms_proxy user to interact with the objects within the luckperms_proxy database, you would need to either:

  1. Grant the necessary privileges on the objects within the database to the luckperms_proxy user, or
  2. Reassign the ownership of the objects within the database to the luckperms_proxy user.

royal hedge
#

idk but relocate gentyref

atomic trail
#

Oh, didn’t know that was required, why?

#

I just use the version from paper or Configurate, forgot where

royal hedge
#

if its inside ur plugin jar it should be relocated

royal hedge
atomic trail
#

I thought it was only if there’s another version at runtime as well

#

For example in the paper jar

royal hedge
#

but because bukkit is so ass class loaders arent isolated

#

so if any other plugin has the same classes youll get conflicts

atomic trail
#

As in 2 libraries at same version

royal hedge
#

like between two plugins?

atomic trail
#

Like if I shade Configurate at exact same version as the one inside the paper jar

#

So both versions are identical, are conflicts then an issue?

royal hedge
#

if its provided by paper you dont even need to shade configurate

atomic trail
#

Yeah bad example

#

But you get the idea?

royal hedge
#

yea

#

ig itll be alr

#

but you cant be sure it doesnt get a breaking update

atomic trail
#

That’s true, so the issue comes if there’s two different versions of same class?

royal hedge
#

yea

atomic trail
#

Gotcha, I don’t think that’s the issue in this case but it might, will try to relocate it tmr

torpid raft
#

/tp snowball coords 😏

#

nah im not sure if there is any easy way to do that, you are probably facing a whole bunch of math

#

but maybe you can use a skeleton ai

#

have it target a thing at that block and fire an arrow, then steal the velocity

#

seems scuffed though

grim oasis
#

really wish i did calculus

torpid raft
#

dkim moment

grim oasis
#

you think so if it was done via setting velocity?

#

not teleporting it constantly

dusky harness
torpid raft
#

i think setting velocity would be fine

grim oasis
dusky harness
#

yeah I forgot abt the velocity

#

but thats gonna be some math/physics 😌

grim oasis
#

just calculating it is something I can't do, yeah

dusky harness
#

the math itself shouldn't be difficult, but finding out what values to put it as probably will

torpid raft
#

nah you should be able to extrapolate the values from your input coords / gravity

grim oasis
#

you'd want to check the speed of a normal snowball and use that speed

#

and gravity

#

yeah

#

then the angle is all you need I suppose, but 🤷‍♀️

#

I don't think player velocity works the same because the player is in control, but I'm guessing

dusky harness
torpid raft
#

yeah i think players have air resistance and other stuff to worry about, i dont think projectiles have that

dusky harness
#

actually there is a wiki where they like decompiled the movement code

dusky harness
grim oasis
#

what about not player

dusky harness
#

I hope it's the same

#

🙃

grim oasis
#

oh yeah, gravity

#

idk what i was even looking at

dusky harness
#

2% drag

torpid raft
#

😏

grim oasis
#

oh you didn't want a snowball really?

dusky harness
#

oh

grim oasis
#

i think the teleporting zombie might be laggy

dusky harness
#

wait whats the end goal

grim oasis
#

i missed that, yeah

dusky harness
#

to move the player?

grim oasis
#

Are you looking for a straight line? or something more like a snowball throw with an arc

torpid raft
#

is the player the one deciding where they are thrown

#

if so ender pearls are your friend

#

or snowballs ig

dusky harness
#

why on an entity?

grim oasis
#

so in an arc?

dusky harness
#

if the end goal is just to make the player fly to a certain location (on an arc), then honestly the best thing here is probably to just make up your own values and do simple trig

torpid raft
dusky harness
#

or else theres gonna be a lot of effort in finding out what values to put velocity as

torpid raft
#

i dont think so, if you can make a program do the math once it can do it a million times

#

then you just draw a preview in-game of the path

dusky harness
torpid raft
#

and you can just eyeball it and export the values you want from there

dusky harness
#

wait wdym make a program to do that

#

like spawn a million snowballs with different velocities and track each location?

torpid raft
#

no

#

like if you're doing the math to determine the arc, you are no loner limited to just using it to throw a snowball

#

you can do whatever you want with that arc

dusky harness
#

if you don't want it to be laggy, it has to follow minecraft's physics with 1 set velocity at the start

torpid raft
#

like say display particles every 0.n blocks

#

yes

dusky harness
#

even like hypixel does /tp i think

grim oasis
#

except 3d

dusky harness
#

oh i forgot about 3d 🥲 (at least with the /tp method though, you can just treat it as two 2d planes i think)

grim oasis
#

🙂

dusky harness
#

o

#

its also partially random

#

don't know how much that impacts it though, but for large distances it wouldn't really work well if you were to set 1 velocity at the start

grim oasis
#

if it's being calculted then shouldn't matter

#

i think

#

man, i really want to try doing this

dusky harness
grim oasis
#

but I don't think I can

#

lol

#

🤣

#

time to learn

dusky harness
#

without air resistance, it's just these 3 equations (x = position)

image.png
grim oasis
#

is that with gravity?

#

constant accelaration down?

dusky harness
grim oasis
dusky harness
grim oasis
#

32 m/s?

dusky harness
dusky harness
grim oasis
#

right...

#

lol

#

some errors tho

#

idk

#

reeddit

#

i would just set a snowball with no velocity and track it's movement

#

figure out gravity ig

#

true

torn heart
#

hello, i am using Citizens API and Sentinel to create some type of bot and i want to send a message to the player when they kill a NPC i tried using onPlayerDeath but that doesnt seems to be working..

    @EventHandler
    public void onPlayerDeath(PlayerDeathEvent event) {
        Player victim = event.getEntity();
        Player killer = victim.getKiller();
        if (killer != null && CitizensAPI.getNPCRegistry().isNPC(victim)) {
            String npcName = CitizensAPI.getNPCRegistry().getNPC(victim).getName().toLowerCase();
            List<String> deathMessages = new ArrayList<>();
            deathMessages.add(" ");
            deathMessages.add(formatColors("&#794dff&lғʟᴀʀᴇ"));
            deathMessages.add(formatColors("&7You defeated " + npcName + "."));
            deathMessages.add(" ");
            for (String message : deathMessages) {
                killer.sendMessage(message);
            }
        }
    }

Probably need to search those plugins apis for a death event.

Have you tried doing a debug to see what the entity type is by returning a message with the event target

#

Probably not going to achieve the desired outcome given the entity is entirely specific to citizens but it could help possibly

you are subclassing a packet, creating your own type

what are you expecting and whats the exact placeholder you are trying to test?

I would like to know if there are any public, available benchmarks comparing using the WorldEdit API vs using NMS directly to set blocks, or if anyone here has already done this comparison and know the answer (how they stack against each other)

I'm curious because I am performing maintenance in a plugin that has to modify a lot of blocks (next to each other, up to 150K blocks), and the current logic is using NMS to do that, but I remembered that WorldEdit has an API to set tons of blocks at once, and I would like to use it instead of NMS if the performance hit is not that big, because that means the plugin won't have to be updated on each major MC update.

#

I know that using WorldEdit API is going to inevitably be slower than NMS, what I wanted to know is if this performance hit was already benchmarked before, so I can make an informed decision faster. I'll benchmark nonetheless, but if you tell me the performance hit is huge I might just skip testing it altogether.

This is how the plugin is currently doing the updates using NMS, if that serves as reference. Since I haven't much experience with NMS, I'm not able to explain the decisions and tradeoffs made by this code snippet.

https://paste.helpch.at/ewugedotoz.typescript

Please ping me if you answer.

hoary scarab
#

I don't know of any publicly posted comparisons, over the years though I've definitely found using nms methods is much faster as you can chose what occurs rather then doing hundreds of updates for setting a few blocks.

#

Also there is a thread posted from 1.14, that still works today, of most of the set block methods and their ranges for performance.

robust flower
minor summit
#

you can disable updates and other side effects when using the WorldEdit API tho

hoary scarab
#

Ah see that's new ^^^

You disable Physics, block updates, light updates, notifiy etc...

I've got a Minecraft plugin which uses a production URL for api requests. Right now I have to manually change the URL and compile the plugin, which really isn't ideal.

I see that people like Aikar have launch flags like -Dusing.aikars.flags=https://mcflags.emc.gs on boot, if I added my own, how can I check this flag within my plugin?

river solstice

ManagementFactory.getRuntimeMXBean()

sterile hinge
#

you want to use System.getProperty(...)

rugged bane
#

Ah thanks folks! Yeah, System.getProperty worked a charm

#

I use a local url for testing, and I've been constantly recompiling when it comes to the production plugin. Of course, it's a pain if you ever forget to change them back, or you commit the local name etc

#

Now I've swapped the code to..

String url = System.getProperty("tebex.analytics.url", String.format("https://analytics.tebex.io/api/v%d", API_VERSION));

Using it like so..

-Dtebex.analytics.url=https://tebexanalytics.test/api/v1

This is a lot easier

dusty frost
#

no config.yml?

rugged bane
# dusty frost no config.yml?

Nice idea, I did consider this option - though this is mainly solely for me to test the plugin with.

If I ever need to test a fresh install, it would be a nightmare to set the value each time.

dusty frost
#

I mean surely you'd need to set the launch property each time anyways? lol

#

idk I had a similar thing when I couldn't figure out how to get Velocity configs to work, ended up just hardcoding the secret for a while lol

pulsar ferry
#

System property best, just set it once on your test environment and don't have to worry about it again

rugged bane
#

Yeah I believe this was my main reason for going down this avenue ^ I have a start.sh file and now I just launch the server and it auto uses my local instance instead.

I can delete the config files and launch it, and never have to change or recompile the plugin

dusty frost
#

at this point just go full .env 😌

which you already do

queen plank
#

What data do I need to save in order to recreate the skull.

#

ah

#

I assume it is one of the values of a Property under the textures key?

#

Unknown which?

ocean raptor
#

yeah it is

queen plank
#

With no way of telling which?

#

Is it encoded in the base64 somehow?

#

It must be right?

ocean raptor
#

yep, its encoded

#

its basically an json string tho

queen plank
#

I don't know how many values there are, I assume not many. But would it be worth getting the correct value instead of saving them all in an array?

#

Or are there typically like 2 values

#

I just don't want a big array taking up a bunch of space

ocean raptor
#

i believe there is already only one skin in textures

#

but it may also include the cape and model

#

i am not sure tho

queen plank
#

Meh, I'll see how much space it takes up. If it annoys me I'll have to do some base 64 mumbo jumbo.

#

you should be fine storing the whatever the value you got

Hi! I'm kind of new so I might make dumb questiosn lol. I'm using an open source plugin and found a bug which I tried to solve at the .java files.

Pretty sure you can pass it a script. Maybe ask n0rska how he does it in ultimate restart

b) modify restart script (reflection even?)

it probably forgot your JDK or something

on IntelliJ, ctrl alt shift S and then I think it's like Project SDK

If I am right even the malware needs to somehow execute the command or maybe rewrite ops.json, but rewriting ops.json will need a server restart iirc, (Sorry if I am wrong). even tho checking it every sec might be a bit unnecessary in my opinion

I thought for NBTTagList you can add all object types not just a single type.

doesn't seem like it 🙃
there's a type byte field preventing it

and its primitive so non null too

Damn. More work 🤦

#

Is there anyway to allow NBTTagList to function the same as List<Object> ?

#

I don't mind rebuilding the list but if I can have all the object in the same list it would be better.

#

Also yes having the same object types fixed it.

dusky harness
#

since mojang has to know how to serialize them

hoary scarab
#

I might be able to but its more work to recheck the object type when being used plus I think the client check for specific NBTTag types.

Whats the best way you found to make it work?

For the portals I just check in a bukkit runnable and remove the text display if needed. For the teleporting I haven't implemented it yet, but I believe you could listen to the teleportation event, as it should get canceled and you can just remove it and send the event again

non-minecraft question
i wanna make api for a discord bot using mongo and someone that wants to use the api needs to like listen to an event (similar to a minecraft plugin ig)
is there any way to achieve this nicely? only way i thought of requires them to spam my api to check for changes

dusky plinth
#

Web sockets

dark garnet
#

L

dusky plinth
#

Just look them up

#

The mdn article is good

#

They are pretty much like an api, but the server will send events to any listening clients

#

So you don't have to constantly ping for updates, the server will just send updates to the client when they are ready

dark garnet
#

ok yeah thats what i wanted but didnt know it was possible thx

dusky plinth
#

No

#

Np

dark garnet
# dusky plinth Np

wait i dont have to do anything to like allow a client to listen right? anyone can just hook in and listen?

dusky plinth
#

For most applications they first require you to send a message to the server through the socket with an api key or something

#

But this would be something you would implement on the server

dark garnet
#

yeah and then like hand out api keys?

dusky plinth
#

Yeah, like they would for a normal api

dark garnet
#

ok

dark garnet
#

doesnt rly make sense since a key is supposed to be like per-service

hoary scarab
#

You can make your bot collect classes (listeners) and run the methods the same way as spigot. (Using annotations)

dusky plinth
dark garnet
dark garnet
dusky harness
#

btw discord api uses/can use websockets for events

#

just listing a real world example

dark garnet
#

yeah i thought i heard of it somewhere

dusky plinth
#

API keys won't really be necessary unless you want a lot of control and knowledge of what every user is doing

hoary scarab
dark garnet
dusky plinth
#

Just rate limiting the number of connections per client IP per hour may be fine for what you are doing

dark garnet
#

yeah think thats what i did for laser tag's api

#

something called bucket overflow rate limiting 🤷‍♂️

dusky plinth
#

If people are abusing it you can implement api keys

#

But that would also require you to make a system where users create accounts, which you have to store

#

If you aren't already doing this it may be unreasonably over complicated

dark garnet
hoary scarab
#

Well it's a discord bot so don't need to store account data just have them interact through that bot or another 😉

dusky plinth
#

Alright, I'm not too familiar with discord bot development

dark garnet
#

yeah if needed can just have a command to generate/get api key

#

wait nvm

#

discord bot not ran on api server

#

actually sitll possible if i make api endpoint to generate keys but require authorization

#

interesting

dusky plinth
#

I mean you should store the api keys and their corresponding discord accounts in a database somewhere

#

So the discord bot can add to this database when a new user creates an api key

#

And the server can read from this database to check that all incoming web socket connections have a valid api key

#

id like to note you shouldn't be using titles to check inventories

#

anyone could just call a chest "Coin Flip" and it'd act the same

#

although im unsure of what exactly you're doing

unborn ivy
#
  1. have different classes for different stuff example: a class to listen to events, a class for Command Executor, a class for Item building etc
  2. Do not ever use menu titles to check inventories, could use something like an enum combined with a HashMap instead
  3. Keep in mind that HashMap values aren’t that reliable for a coin flipping plugin because player bets will be removed if the server restarts
#

You can solve 3 easily by giving the player their money back in leave event, or in onDisable by having a for loop, but then other players wouldnt be able to take other offline players coin flip games

#

i also have no idea what you’re trying to do with the coin flip plugin anyway, i’ve made one recently and i can help you out a bit

unborn ivy
#

what are you looking for exactly

#

you should have some kind of prototype or template

#

like what kind of inventory you want, what you wanna display on it

#

then you can figure out what to do from there

#

e.g. your coding structure

#

take a look

#

if (inventory != null && inventory.getName().equals("Coin Flip")) {

#

you are checking if the inventory name is Coin Flip

#

so someone could just get a normal chest

#

and call it Coin Flip

#

and then it would execute code

#

you dont want that

#

so like what i said earlier, you can use a HashMap combined with an enum

# 
public enum MenuState {
  MAIN_MENU,
  ROLLING_MENU
}
#

something like this

#

then you have another class called PlayerStateManager, create methods like getState#, setState# and deleteState# to make your work easier

#

then to check if a player is actually in the menu, you open the menu somewhere and use the setState# method

tight junco
#

enum isn't the best either to be fully honest

unborn ivy
#

what do you mean

unborn ivy
tight junco
#

InventoryHolder

unborn ivy
#

well if hes using a static inventory he cant do that

#

but if he wants to display info like profit, amount of wins/losses, then sure

#

inventoryholder is the way to go

#

from his code seems like hes using a static inventory

#

or global inventory i should say

tight junco
#

public class X extends InventoryHolder // do whatever
createInventory(this)

new X()

if (!(event.getInventory().getHolder() instanceof X)) return

#

yk

unborn ivy
#

then i just register the click and close events

#

and unregister them when the menu is closed

tight junco
unborn ivy
tight junco
#

but honestly if they're that new to plugin development, frameworks are better until they have a solid grasp on spigot api (and obviously studying how the framework actually functions is important too but)

unborn ivy
#

what does your client want

#

a gambling plugin right

#

o

#

so how is your game going to work

#

you bet $500, guess a random number to win money?

#

ok

#

so whats going to happen when the command runs

#

define your check clearly

tight junco
#

it would be correct, it might get by with different wording but meh

unborn ivy
#

selling stuff to people that give them a gameplay advantage is against the mojang EULA

#

afaik gambling plugins arent

tight junco
#

they updated the guidelines where the server has to be like, friendly to all ages

unborn ivy
#

thats common sense

the server i work for had to remove our "lottery" plugin

unborn ivy
#

im quitting, time to host a SMP server

#

no shit but mojang is mojang

#

they dont play around ever since that tf2 mann co supply stunt back in april fools a long time ago

tight junco
#

here's the exact guideline

IMG_5685.png
#

as far as compliance goes, at a certain point they just send an employee on your server to briefly search the features (check if chances are on crates and looking out for certain things, haven't seen them do an in-depth search though)

unborn ivy
#

time to ban every mojang staff member known to existence

tight junco
#

the account is called MCEnforcement

#

and they'll tell you they're showing up beforehand, or atleast they did for us

#

although that likely won't happen unless your server blows up or you try to put it on the official mc server list

unborn ivy
#

not if i ban that account

tight junco
#

they'll either send a different account or blacklist the server because you banned the account prior

unborn ivy
#

also does anyone know how to send a TextComponent as part of a message e.g. click HERE where only HERE has hover and click actions

stuck hearth
#

No way minecraft can make more minecraft accounts

tight junco
#

depends what text component you're on about

unborn ivy
#

err

#

dont understand what you mean

tight junco
#

kyori/minimessage or vanilla

unborn ivy
#

vanilla

tight junco
#

although i believe there's a component builder somewhere

#

and you'd just have to append a new component with the hover events and such onto the previous component

unborn ivy
#

sounds mind boggling considering im doing all this in AsyncPlayerChatEvent

tight junco
#

correct!!

unborn ivy
#

so after appending all that bs

#

i cant just turn it back into a string to use e.setFormat

#

im basically stuck after that then

tight junco
#

lol probably not

#

it's easier when using kyori (bundled with paper api) by a significant margin because spigots text component system can be really jank

#

most chat plugins to memory will just redo the chat system and overwrite it with their own messages that are individually sent

unborn ivy
tight junco
#

i think it's just operate on event priority HIGHEST or MONITOR with ignoreCancelled and it'll send whatever messages go through whatever other plugins are listening for chat messages

#

but the actual message event itself gets cancelled at the end every time

I have this bit of code to launch an entity in a direction. It works fine when the multiplier is 1, but when I increase it the target becomes really inaccurate. Why is this? In my head multiplying the vector should not affect the angle? Pls ping if you respond :)

double multiplier = /* My multiplier */;
entity.setVelocity(vector.multiply(multiplier));

Is it simple enough to create a JS placeholder that will return 'true' if the item in a player's hand is a certain ID?

I haven't touched the player side of stuff, only permission checking in existing scripts.

Yes, but I would advise using the changeoutput expansion + player expansion

should be more efficient than using a js placeholder (since a new javascript engine has to be started every time a js placeholder is called)

I used to create a single package-info.java file at the project root's src folder in order to have everything annotated with @NotNull by default.

@DefaultQualifier(value = NotNull.class, locations = {TypeUseLocation.PARAMETER, TypeUseLocation.RECEIVER, TypeUseLocation.RETURN, TypeUseLocation.CONSTRUCTOR_RESULT})
package net.countercraft;

  compileOnly("org.checkerframework:checker-qual:3.42.0")

I'm trying to use that same setup in another existing Java project, but the IDE is not catching up. RemoteControlledCraft is a simple interface that had its getCraft method annotated with @NotNull, and if I comment it out, Kotlin doesn't pick that the field is non-nullable, even after I've added the package-info.java file.

How could I fix this?

Hello. I am currently building a multi-module gradle project, and here is what the main file looks like: https://paste.helpch.at/afejabaxin.java

sure..? but why does that matter

#

it doesn't include any of the useful info thonk so why is it relevant

hoary scarab
#

Unless I go through all the item meta from the minecraft itemstack thats the only data available.
I can check later if the item data is in the minecraft itemstack class but was to lazy earlier.

Anyways from itemstack -> minecraft itemstack -> itemstack it loses the ItemMeta

minor summit
#

how are you verifying that? it works fine for me

hoary scarab
#

Giving myself the item before and after

#

So now I'm just reapplying the itemmeta on the returned itemstack.

minor summit
#

idk, it certainly works fine and it's been working for over a decade lol

#

would be nice to see some code

hoary scarab
#

Can't right now. Can send it later.

# 
Object minecraft_item = nbt.asMinecraft(item);
nbt.setTag(minecraft_item, tag);
            
item = nbt.asBukkit(minecraft_item);
item.setItemMeta(meta);

Heres all I can send for now.

minor summit
#

this is my code

final var bukkit = new org.bukkit.inventory.ItemStack(Material.IRON_INGOT);
bukkit.editMeta(meta -> meta.displayName(Component.text("stink")));
final var vanilla = CraftItemStack.asNMSCopy(bukkit);
final var bukkit2 = CraftItemStack.asBukkitCopy(vanilla);
final var bukkit3 = CraftItemStack.asCraftMirror(vanilla);
getSLF4JLogger().info("{}\n{}\n{}", bukkit.getItemMeta(), bukkit2.getItemMeta(), bukkit3.getItemMeta());

and this is what it logs

[Paper-Test-Plugin] UNSPECIFIC_META:{meta-type=UNSPECIFIC, display-name="stink"}
UNSPECIFIC_META:{meta-type=UNSPECIFIC, display-name="stink"}
UNSPECIFIC_META:{meta-type=UNSPECIFIC, display-name="stink"}

Mine

Object nmsItemStack = asNMSCopy(itemStack);
Object itemCompound = getTag(nmsItemStack);

setString(itemCompound, key, value);
setTag(nmsItemStack, itemCompound);

return asBukkitCopy(nmsItemStack);

Also been working for years

hoary scarab
#

Thats why I'm questioning it just stopped working for me.

minor summit
#

i believe this is what the kids nowadays call a skill issue

#

the itemmeta is certainly retained, but i wouldn't be surprised if spigot/minecraft removed foreign tags at some point, i know that's a thing that happens with entities, not itemstacks but who knows

hoary scarab
#

Ill do more debugging later. Weird that its causing an issue now.

hoary scarab
#

Sigh nbt.setTag(minecraft_item, tag);
tag is null so I was essentially erasing the display tag after I set the item meta.

Made sure to copy tags from the minecraft_item onto the new tag.

Oh wow this is actually perfect I think, thanks

Is there a way to tell what type of villager a villager is? Like a jungle villager or a desert villager

im having flat out errors with my permissions in my server

essentialsx is somehow having an interference with everything and customcraftings just disabled itself

torpid raft

that's awful, consider undoing whatever you most recently changed

stuck hearth
#

mmm yes

torpid raft
#

also probably better to ask for help about that kinda stuff in #minecraft

Yeahhhh just found that as well, protocollib has 895 open issues tho lol

I doubt it'll get fixed soon

#

What do you guys think, Exlll ConfigLib vs Spongepowered Configurate?

stuck hearth
#

I love configurate, never used the other
I also use hocon fwiw

atomic trail
#

Never really why hocon is used, what's better about it?

stuck hearth
#

I started in sponge and it's just the standard there.
I find it more readable + it has comment support whereas configurate I don't think supports yaml comments (yet)

atomic trail
#

Yeah there's a working pr with comment support which I use tho

stuck hearth
#

Oh yeah I remember you

But I have made a wrapper so it's not really an issue, it just looks so simple

#

configurate supports inheritance too?

#

although it isn't really configurate that handles that, but the underlying serializer library, but they all support that

# pulsar ferry Hocon my beloved

I've got a question for you actually, is it possible to remove the player inventory for a gui? So it only shows the gui I created

pulsar ferry
#

Yes with resource packs

atomic trail
#

Ah, so not with just the api

atomic trail
#

I'm still very new to kotlin, is this like a record in java?

class PetItem(
    private val plugin: EcoPlugin,
    private val pet: Pet
)
#

So it adds those fields through constructor?

worn jasper
#

thought that were data classes

worn jasper
#

these are like records

atomic trail
#

Ah gotcha, but what I sent above adds to the constructor and adds the required fields right?

worn jasper

#

In Kotlin when you do private val/var you create a "property" which is composed by a field, a getter, and if var a setter

class Test(plugin: EcoPlugin)
// Equivalent to
class Test {
  
  public Test(EcoPlugin plugin) {}
}
// While
class Test(private val plugin: EcoPlugin)
// Equivalent to
class Test {
  
  private final EcoPlugin plugin;

  public Test(EcoPlugin plugin) {
    this.plugin = plugin;
  }

  private EcoPlugin getPlugin() {
    return this.plugin;
  }
}

eyo that's quite a cool hack

#

reminds me of lambda type hacks lmao

pulsar ferry
#

"hack"?

worn jasper
#

like, a way to do something quicker

#

I call it hacks xD

pulsar ferry
#

At best "syntax sugar" is what this would be, but still it isn't since it's a different language that works differently, that's why I say equivalent, because it isn't exactly that

worn jasper
#

yeah fair enough

#

although I have never fully understood why everyone hates lambda... I personally don't use but idk
