question for curiosity sake, if i make a plugin's database logging log someone's uuid and username on join, and a server is running in offline mode, and a cracked player joins the server, what happens? do cracked players have uuids assigned to them by the server or naw

no you told me to learn java

hey olivo, i'm trying to create a command
i'm implementing CommandExecutor as one of the interfaces of my plugin
the onCommand function has some parameters i'm confused about
can you offer any explanation?
i want the server hoster to be able to set some properties in the config file through the console
pastel stag
what are the params of the function you are confused about
chrome beacon
^
formal dome
onCommand(CommandSender sender, Command command, String label, String[] args)
pastel stag
which
formal dome
so i don't know how to set CommandSender
i want it to be a command sent from the console only
pastel stag
CommandSender is the sender of the command, whether thats console or instance of a player
formal dome
server hoster should be the only one be able to set it
chrome beacon
Then check if it's an instance of ConsoleSender
formal dome
okay, so let me try to describe this.... is the sender passed in by the api ?
kinda like an event ?
pastel stag
yes
formal dome
okay cool thanks
pastel stag
CommandSender is passed in
formal dome
well there are some commands that can only be sent in the server console
so i wouldn't think so
pastel stag
@lean gull if you look up and gain an understanding of how instances work in java i think you will see what is wrong w/ your code

formal dome
i want to learn the basics along the way
i hear ya. well, at the very least you should learn the basics of what applies to what you're doing
it will make it a lot easier
you don't have to go learn all the basics. that's too much as well
lean gull
i'll try googling it and i will probably come back immediatly with questions about it lol

iirc that's the standard for NBT APIs if you're not using PDC

sharp bough
https://paste.md-5.net/ohutemayof.java
why are you using titles to check invs?
quaint mantle
plus idk how to do loot tables in spigot
worldly ingot
The purpose of PDC was to avoid polluting the root NBT of an item and hide everything under Bukkit's namespace. Ideally nothing on the root NBT should be added/edited by a plugin because we have ItemMeta for that
That's the reason you can't access any tag from there, only ones defined by plugins

quaint mantle
and if you are using a class for a single command then you dont need to check if label is the command name
hybrid spoke

go over the command
the label is for being very specific
quaint mantle
i know u can use command.getString() as well
worldly ingot
getName(), yes. The preferred way
quaint mantle
getName(), yes. The preferred way
ah yes getName() : )
worldly ingot
The label is useful for command feedback and label-specific execution
quaint mantle
i just prefer to make individual classes for each command and define aliases
quaint mantle
The label is useful for command feedback and label-specific execution

Yeah definitely
formal dome
HAH
i'm happy i was doing it the right way lol
without looking at the tutorial first
quaint mantle
ye the thing is, even tho i gave myself the item with an nbt that i added, when i run it, it says that the nbttagcompound is null
worldly ingot
nms.ItemStack#getTag() will only return null if the item has no NBT at all
quaint mantle
@EventHandler
public void OnBottleBreak(ProjectileLaunchEvent e) {
Projectile projectile = e.getEntity();
if (projectile.getShooter() instanceof Player) {
Player p = (Player) projectile.getShooter();
ItemStack item = p.getItemInUse();
net.minecraft.world.item.ItemStack nmsItem = CraftItemStack.asNMSCopy(item);
NBTTagCompound nbtTag = nmsItem.getTag();
for (String string : nbtTag.getKeys()) {
System.out.println(string);
}
}
}
this gives that nbtTag object is null
quaint mantle
nms.ItemStack#getTag() will only return null if the item has no NBT at all
btw, what does # mean?
in java ofc
worldly ingot
Javadoc notation. Methods are referred to using #
quaint mantle
oh
worldly ingot
getItemInUse() is the item being consumed by the player (i.e. food, or a potion)
You probably want player.getInventory().getItemInMainHand()
worldly ingot
(if you want to be really fancy you can account for multiple hands by doing a null/air check then grabbing the other hand)
ItemStack item = player.getInventory().getItemInMainHand()
// If there was no item in the main hand, get the item in the off hand
if (item == null) {
item = player.getInventory().getItemInOffHand();
}
// There wasn't an item in the main or the off hand. Don't proceed
if (item == null) {
return;
}```what about quickly switching hands
like sword swap maybe
maiden briar
I have no idea what is happening here
worldly ingot
what about quickly switching hands
Won't be any issue because the item will be in the same spot when the event calls

golden turret

Hit is a bit different. But to work around that you could just keep track of the arrow on launch then compare it in the hit method

You're creating a new instance which means it isn't set anymore
ok so i now know what an instance and what an object is, and from what i understand, you mean that in the main class i have an object of config manager, and in tab manager i have another one?
i tried doing this in main:
public ConfigManager getConfigManager() {
return cfgm;
}```and this in the tab manager class:
```java
public TabManager() {
cfgm = MangaTab.getConfigManager();
cfgm.reloadTab();
FileConfiguration tabConfigFile = cfgm.getTab();
tabConfigFile.set("banana", "yes");
cfgm.saveTab();

Hello, I'm currently trying to change the amount of items certain recipes give, but and just set up custom crafting recipes, hoping they'd override the vanilla ones, but that didn't seem to work. Does anyone know of a method I could use.
(Notes: I am new to Java; This is for Spigot 1.17.1; I have tried google, but I didn't find anything (although that might just be me not using the right keywords))
covert remnant
I have attempted updating the amount by creating custom recipes with the same crafting table input, hoping it'd just override the vanilla recipes.
covert remnant
public class ___ {
public void ___() {
ItemStack result = new ItemStack(Material.ACACIA_STAIRS,8);
NamespacedKey key = new NamespacedKey((Plugin) this, "___");
ShapedRecipe recipe = new ShapedRecipe(key, result);
recipe.shape(
"X ",
"XX ",
"XXX"
);
recipe.setIngredient('X', Material.___);
Bukkit.addRecipe(recipe);
}
glossy venture
so the first in the list gets recognized first
minecraft recipes are first so you will have to either put yours before it
or remove the other one
covert remnant
How do I remove a recipe though?
glossy venture
no clue
covert remnant
Me neither, and I've tried googling. :/
glossy venture
maybe using Bukkit.getRecipe()
to get the vanilla recipe
and edit it?
what item craft are you trying to overwrite
ohk acacia stairs
try ```java
((ShapedRecipe)Bukkit.getRecipe(new NamespacedKey("minecraft", "acacia_stairs"))).getResult().setAmount(amount)
idk if it will work
/* get recipe and cast to shaped crafting recipe */
ShapedRecipe recipe = (ShapedRecipe) Bukkit.getRecipe(
new NamespacedKey("minecraft", "acacia_stairs") // key, same as "minecraft:acacia_stairs" in text
);
/* set amount of result */
recipe.getResult().setAmount(amount);
Imma test it out now.
public void ___() {
String item = "";
Bukkit.getRecipe(new NamespacedKey("minecraft", item)).getResult().setAmount(_);
}

Yeah, I thought so
tardy delta
doesnt "namespace:key" works as only parameter?
so only one string?

lean gull
btw what i'm trying to achieve here is a tab plugin that has a footer and a header, each of them has 5 lines
tardy delta
what is the purpose of a TabManager instance?
also a constructor is the way to do it
public void getPluginConfig(MangaTab plugin) {
this.plugin = plugin;
}
and all of that is stored by something like this:
# each line is stored from line 1 to line 5, top to bottom
header:
line1:
line2: aa
line3:
(etc etc)```so a comment, a section, and 5 keys and their values
and if the value is not set then it will not count it as a line
tardy delta
and what exactly are you trying to achieve?
tardy delta
so just saving a header & footer into the config file?
lean gull
wdym
the header and footer of all players' tab would be what you set there, and if a value is empty then it won't be counted as anything
tardy delta
you're saying your plugin has a footer and a header so probably you're going to save them somewhere
hasty prawn
So what is the issue, Derpy?
lean gull
and all of that is stored by something like this:
```java
# each line is stored ...
this is an example for what i want the config file to look like
tardy delta
why not just using the FileConfiguration class?
to get values from config
like plugin.getConfig() -> return the config.yml fileconfig
and just set your things there?
covert remnant
Are you saying I have to call "Bukkit.getRecipe(public NamespaceKey(@NotNull Plugin plugin, @NotNull String key))" then, cuz I'm pretty sure that 'aint gonna work. I'm trying to edit an existing recipe, and need the "minecraft" namespace keys, not my plugins'.
tardy delta
just a Plugin and a String as parameter
btw the minecraft namespace isnt tht just ```java
var key = NameSpacedKey.minecraft("stone");

i think its just

How can I create a custom World, for example a plot world?

Can I use Java 16/17 SDK for compiling pre-1.17 plugins? Will there be any issues?
hasty prawn
Pretty sure it won't work
gritty urchin
Even if I use it to run the server jar?

I mean you can certainly try it, I've just not really seen Java 16/17 work well with Minecraft versions that aren't 1.17

Inventory inv = Bukkit.createInventory(null, 9, "§aChosse a player");
for (Player players : Bukkit.getOnlinePlayers()) {
ItemStack skull = new ItemStack(Material.SKULL_ITEM, 1, (short) 3);
ItemMeta meta = skull.getItemMeta();
meta.setDisplayName("§e§l" + players.getName());
skull.setItemMeta(meta);
inv.addItem(skull);

How can i change the texture of the skullitem to the texture of the playergoogled it?

you need to parse the item meta as skull meta

idk what's wrong
probably sodium has a memory leak

you will have to make a custom block populator
i think its called

then just set the world type to flat

you will have to make a custom block populator
do u have a piece of code for me, i watched a ton of tutorials but they dont show how to create it with like a command. It would be really helpful
glossy venture
wdym by with a command?
you mean when they run a command they create a new world
?
pastel mauve
I would like to create the would with a command. The tutorials always use the bukkit.yml the create it or something old like multiworld
pastel mauve
not at all lol

Sounds like you are looking to configure your server not write a plugin
nah
hes writing a plugin

its still not fixed

its going to be fixed in sodium 0.3.3 it seems

Sodium still better than OptiFine imo
well, resourcepack features

What exactly are you doing with chunkgen?
mortal hare
idk guys but vanilla minecraft runs better than running sodium or optifine
i'm getting 300 fps
on vanilla
while on sodium i get 200-250
opal juniper
🆒
karmic mural
I get lower FPS on Optifine but that's because I opt for higher quality
I do get more consistent FPS with Optifine vs Vanilla, though. So regardless the fps drop is weighed up for by better graphics and smoother framerate
But this is more #general isn't it?
mortal hare
Mojang really polished their graphical engine for caves and cliffs update
to get more fps
mortal hare
no

Server Resource Pack
wary harness
is Crafting even string
?
karmic mural
No, it's literally in the textures

Get a resource pack with what you want it to say, then force that as a server pack

What's the best way to make an area system where you can create areas and customize their permissions and add/modify owner and co-owner?
By replacing Group with a new name and UUID with the name of the area, would it work?
formal dome
what are the various command permissions you can use in your plugin.yml?
commands:
setDiscordIDs:
description: Sets your desired Guild and Channel for interaction
usage: /<command>
permission: BroadcastReader.
the example from spigot
# Replace "kit" with the name of your command.
commands:
kit:
description: Your description
usage: /<command>
permission: yourplugin.yourcommandpermission ```is there like op only?
console only?

hello everyone, I want to make a plugin, that broadcasts over 2 (or more) servers. Here's the example out of the Thread on SpigotMC:
I want to for example send a broadcast message from one server to another.
So something like:
server1 executes /winner foobarbaz, sends a message to server2, says "hey, please broadcast, that foobarbaz has won!"
If you have an answer, that works for me, I would like to copy it in the Thread or you write it directly in there^^
(I'm not impatient, just wanna spread my issue lol)

Would PlayerChangedWorldEvent be a good event to check coordinates of a player to see if he enters a custom region?
mortal hare
Is it me or the PlayerChangedWorldEvent makes the the previously stored player object stale
i get two different world names
quaint mantle
hm?
mortal hare
I've checked the world name in the event.getPlayer().getWorld() and previously stored player object in hashmap and it turns out after PlayerChangedWorldEvent, player object gets stale, since world names do no match. Hashmap stored value retrieves the old world name while the event.getPlayer() player object retrieves new world name
nice
I wasted 7 hours
debugging this
thinking it was my fault in my algorithm
i thought Player object are stale only when player disconnects
or rejoins
turns out even world change can make it stale
since player object changes, whenever world changes in NMS
quaint mantle
Thats why you really shoudnt use player references
quaint mantle
Players are entites, and they are bound to the world
mortal hare
i thought i was going to save some cpu power by not using getters to get the uuid everytime
since im utilising intensive events
like playermoveevent
and entitymoveevent
sullen marlin
no that's wrong
player objects do only go stale after a disconnect
what version of spigot are you running, post /version
mortal hare
then why world objects stored in player are different wtf
quaint mantle
ah
mortal hare
PlayerChangedEvent Player reference:
[23:08:03 INFO]: [DEBUG]: Player's current world name: world
Stored Player reference in hashmap:
[23:08:03 INFO]: [DEBUG]: Player's world: flat
all i did
is changed dimensions

Why arent my config functions working
this.getCommand("setDiscordIDs").setExecutor(this);
this.getConfig().addDefault("guild-id", 0);
this.getConfig().addDefault("channel-id", 0);
this.saveDefaultConfig();```.
saveDefaultConfig copies the config from your jar
mortal hare
im running airplane
sullen marlin
if you are using addDefault you want regular saveConfig
@mortal hare so not spigot and almost probably a bug they've introduced
mortal hare
This server is running Airplane version git-Airplane-99 (MC: 1.17.1) (Implementing API version 1.17.1-R0.1-SNAPSHOT) (Git: e68f5c2 on HEAD)

how do you check if the server has a world by name

how do you check if the server has a world by name
Bukkit.getWorld("name");
and then check if it's null or not
if not null then the world exists

the server may still have a world with that name as a folder

what API are u talking about?

it's... not an API? and what about "refactoring" it? what do u mean?
and what I did is not done yet don't worry, I just wanted to make sure I'm not doing shitty work before doing more

I mean when the Area framework will grow, you will refactor the classes sooner or later

dont do this
don't do what? making my HashMap public?

static
paper viper
The point of managers is to hold this stuff inside the actual instance not like to be static
there is only supposed to be 1 manager
so put your map in there
instead of using static
mortal hare
I name my managers registry's but im not sure if that's the proper name for them
all of my managers do is register deregister things
rough jay
but I separate my managers to avoid having a 2k lines file
paper viper
and stuff
paper viper
but I separate my managers to avoid having a 2k lines file
that doesnt have anything to do with static
rough jay
you said there is only 1 Manager
paper viper
but its a registry. It registers stuff
i dont think it matters too much
paper viper
you said there is only 1 Manager
Yeah
if there is only 1 manager
no need to make it static
just put the map inside your actual manager class
rough jay
uh I'm not sure to understand what you're saying
if there is only 1 manager
I don't have 1 manager but 2
paper viper
1 manager instance
What you are currently doing is trying to store your map like a singleton. Singletons are something which is only defined once. However, your AreaManager class is a Manager class already, meaning there should only be 1 instance of AreaManager in your plugin. Therefore, you don't have to turn your Map into a singleton and you should remove the static.
rough jay
but my map is already inside AreaManager so it's inside the class
I know there is only 1 instance of AreaManager, it is defined in MaxiCity.java
rough jay
just put the map inside your actual manager class
do I remove the static or do I put the map inside my manager class???
mortal hare
java oop experts be like
paper viper
> just put the map inside your actual manager class
do I remove the static or do...
remove the static
paper viper
without static
no need to make it static
should remove the static.
remove the static
🥲
young knoll
public maps?
paper viper
And encapsulate it
rough jay
> without static
he said just put the map inside your actual manager class
he lost me because my map is already in my manager's class that's why
anyways, everything's good now

i dont fucking get it
in one world
packet entity
always spawns
but in another
it just doesnt
no matter what i do
mortal hare
its not as if its not sending packets
it does
the client just doesnt render
for some fucking reason
but in another world
it does
i've debugged all the if statements
that could cause packets not to be sent
nothing
i tried adding tick delay
via scheduler
it adds after one second
in the flat world
while in another dimension it doesnt
im so pissed
ivory sleet
You know editing messages is a thing 😄
unkempt peak
Are you sending the packet to each world?
mortal hare
wdym by each world. im using player's connection to send the packet
via spawn entity living packet
unkempt peak
Yes are you spawning said entity in each world?
mortal hare
im sending destroy packet at the worldchangeevent and then resend the spawn entity living packet
spawn entity living doesn't have a field for dimension UUID
unkempt peak
Ok and it's spawning it in the wrong world?
mortal hare
im not sure
unkempt peak
What world are you trying to spawn it in?
mortal hare
but it doesnt spawn in the right world
at the right time
survival
none of the dimensions do not work
apart from one
unkempt peak
And your trying to spawn it if somone joins the survival world?
mortal hare
as i said im spawning an entity whenever PlayerWorldChangeEvent hits
unkempt peak
that event has 2 locations it has a from and a to which one are you trying to spawn it at?
mortal hare
it doesnt matter
i dont use these getters
since protocol of packet doesnt require it
unkempt peak
Where are you getting the location from then?
unkempt peak
Sorry I gtg I'll be back in about 30m dm me if you still need help

how do you change the value of a default in the config.yml
so i've added it already, now i want to change it
@Override
public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String label, @NotNull String[] args) {
if(sender instanceof ConsoleCommandSender) {
config.addDefault("guild-id", args[0]);
config.addDefault("channel-id", args[1]);
getConfig().options().copyDefaults(true);
saveConfig();
return true;
}```so im' trying to figure out why it doesn't change everytime i run the command
i set some values the first time and it worked... now everytime i run the command it defaults to those values
i guess that's why it's called default eh
AH i figured it out
theres an inherited method in FileConfiguration from ConfigurationSection called set 🙂
that does the trick
hasty prawn
Probably just set it to that value if it's null maybe? When you use saveDefaultConfig? 
🤷♂️
waxen plinth
Man
People really be out here writing commands like this
@NotNull CommandSender sender, @NotNull Command command, @NotNull String label, @NotNull String[] args

And all that for just a few lines of logic

People really be out here writing commands like this
If only there was a lib what makes this 10x easier

Well at the very least you don't need the @NotNull annotations because it's not an API method or anything

Sure would be nice if the exception told you exactly what was happening and where
quaint mantle
mhm
waxen plinth
but its not null
Well the exception seems to disagree
waxen plinth
I feel like a simple null check would fix this
Just early return if the nbt tag is null
quaint mantle
can someone help me, im using this code:
```
@EventHandler
public void onBot...
i clearly put bottleType:grand here
waxen plinth
If the nbt tag is null then it won't have the data you want to begin with
waxen plinth
It's entirely possible that minecraft just ignores nbt data you put in the item that it doesn't think exists
Try throwing the item on the ground and using /data get entity @e[type=item,distance=0..5] or whatever
quaint mantle

okay
waxen plinth
It might not have had the tag applied at all
In which case you would have to apply it programmatically
quaint mantle
any reasons for that?

Might just be how the game is written
Not sure why you're using nbt api to begin with
quaint mantle
i want to use this item in datapack loot tables
waxen plinth
You could easily use PDC for this
quaint mantle
You could easily use PDC for this
ik that would be so much easier
waxen plinth
I don't think plugins and data packs mingle very well
So I wouldn't know how to help further with that
waxen plinth
PDC must be represented in some structure in NBT
Where else would it be stored
I'm guessing it just puts a special map in the NBT data for an item or something
quaint mantle
yuh
waxen plinth
It depends on what you want to do with them
quaint mantle
i want to modify almost all vanilla structure loot tables

PSA: If the exception says a value is null, then it's null. It cannot lie as the exception is raised by Java (the JVM) itself.

you know what I mean
lavish hemlock
also it's hard for fake NPEs to exist lol
quaint mantle
maybe the way im checking for em is wrong
plus one thing i noticed, the exception only throws when i use the item in survival
lavish hemlock
I believe it's throwing bc the item isn't guaranteed to have a tag?
quaint mantle
I believe it's throwing bc the item isn't guaranteed to have a tag?
ye about that, at first i was using projectilehit event and i used a for loop to print all strings in nbtTag.getKeys() metod
and it displayed bottleType as an nbt
@lavish hemlock help pls

use packetdataserializers
in newer versions of minecraft
it allows packet construction without reflection overhead
although packetdataserializer methods are obfuscated you can find out what those do by just looking at the PacketPlayOut class and comparing it to wiki.vg documentation
for example in 1.17.1
#PacketDataSerializer.d() would write minecraft implementation of VarInt to the buffer
by using these you can create packets without reflection

Should i cache SQL data or is getting the data from the database every time fine?
pastel stag
never heard of caching data from an sql database and not just fetching it
i would imagine just using the database as intended would be plenty fast enough for pretty much any possible minecraft related use-case

Yes lol
You most certainly want to cache it
ornate heart
Why
ivory sleet
First and foremost querying sql is quite the operation, so it should be done async to avoid lag spikes as it’s not just any "function invocation" you’re doing there. Because of this you probably want to store the data retrieved from the database, such that if you’ve queried the database once, there’s no need to do it again. However, if you implement a cache you need to be damn disciplined such that you keep your cache in sync with the database regarding all data, and invalidate unneeded objects in the cache which might be after a certain duration.
quaint mantle
Should i cache SQL data or is getting the data from the database every time fine...
well, getting data from db everytime may be a reasonable design, especially with cross-server software, but that requires complex asynchornous design. Even with this you need to cache stuff which is being checked oftenly
ivory sleet
You probably want to use a sophisticated cache if it’s across servers like redis
But that’d require even more discipline

I used to think that i should keep everything in memory, but dam this plugin design is soo awesome

I have idea that I think its possible - since X-rays are very popular and its hard to stop x-rayers that want ORES why not we to stop ores - the server is hiding ores by changing the whole block to stone and if you mine block next to the ORE or close to the ORE its transofrming into ore so the player really must "find" it...
Would it be possible to implement in BIG servers?

Apart from not using gradle it’s quite nice

that is what the dev of paper thought, and you know what? they even made a system built-in to paper. if you interested in that then i can link you to a post about it lol
