[violet niche]

I am

[hardy swan]

ok, firstly, it that on that head of the player

if so, you do not need armor stand

[grand swan]

@quaint mantle please refer to the premium resource guidelines.

[summer scroll]

the backpack is on the armor stand helmet equipment

here's my method https://paste.md-5.net/zosovamiji.cpp

[grand swan]

@quaint mantle I will quote for you:
https://www.spigotmc.org/threads/premium-resource-guidelines.31667/

Please do not contact us regarding ETAs

[eternal oxide]

one sec...

[hardy swan]

oh wat?! there is a passenger method.... Im missing a lot

frick

in that case, can't you set the backpack as the passenger itself?

[summer scroll]

the backpack is an itemstack with custom model data

[violet niche]

K good, "real" players get added to the usercache, so they're being distinguished in some way

[eternal oxide]

You cna compare the UUID of the returned player to UUID.nameUUIDFromBytes(("OfflinePlayer:"+name).getBytes(Charsets.UTF_8)); If its a match then its not a realy player (unless in ofline mode.

[summer scroll]

and afaik armor cannot have custom model data

[violet niche]

ewww haha

[hardy swan]

ohhh passenger must be entity

[eternal oxide]

I remember it returning with a null name but I guess it no longer does

[summer scroll]

armor stand is a entity

[hardy swan]

yes wat i meant is, I thought you could just add the backpack as a passenger

self-realization exclamation

[violet niche]

Where are the sources you just looked at?

[eternal oxide]

I was looking at my own util classes, but that line is pulled directly from Bukkit.

[violet niche]

yea I was wondering where was good to read them

[eternal oxide]

I just use the decompiled sources BuildTools generates

[violet niche]

great

[summer scroll]

so, are there any solution?

[hardy swan]

err try setting gravity false, tho I dun think it really matters

also just use one of the visibility methods

.setVisible(false) should suffice

[summer scroll]

Wait, I'm having like a weird problem.

So I'm trying to spawn an armor stand, but it's automatically be the player's passengers.

[hardy swan]

when did you call equipBackpack() lol

[eternal oxide]

Do you mean you want to it be the players passenger or it already is?

[summer scroll]

I was testing without that method.

Hold on, I'm gonna do some couple of testing

[hardy swan]

o.O, definitely called setPassenger somewhere

[hardy swan]

he was creating a backpack cosmetics, but he now has the armorstand on passenger whenever he spawns one even without the equipBackpack() method

[summer scroll]

The armor stand is already on the player passengers even though I didn't add the passenger onto the player.

[hardy swan]

try killin the entity and try again

[summer scroll]

kay, i think i fixed it smh

ah finally, thanks guys!

[quiet ice]

sighs "wont work" is not telling us much

[hybrid spoke]

when are you calling this?

[quiet ice]

try to delay it by a tick and see if that changes it

[hybrid spoke]

delay it

scheduler

runTaskLater or runTask

the event doesn't count that player, which just entered the bed. just a tick later the player will be added or better said the player will be sleeping

[violet niche]

Can I execute a command on behalf of a player?

[hybrid spoke]

player#chat(command);

no need to wait a whole second. 1 tick is enough.

also you won't need that BukkitTask task =

in the task. otherwise you will have the same problem again

[quaint mantle]

can i change item nbt in player's inventory without giving item?(inventory.setItemInMainHand(ITEM))

it is

try: .setTime(world.getTime() + 24000)
24000 = 1 day

Player#getHealth()/Player#getMaxHeatlh() * 10

ehm? wha?

[quiet ice]

Player#getMaxHealth is deprecated I think

[sacred vector]

how can i make it so my custom item can not be placed on the ground

like it stops them from doing it, so the attributes of the item stay

[hybrid spoke]

cancel the block place event 🤔

[violet niche]

Can I do this and bypass the permission check?

[hybrid spoke]

i am not sure what you mean by permission check. #chat just lets the player chat the given message just like he would type it

[violet niche]

I want to run a command that the player might not have the permission to run

[quiet ice]

many abuse the hell out of setop

[violet niche]

I think Bukkit.getConsoleSender() might do it

[hybrid spoke]

i am not sure if #performCommand bypasses the needed permissions but i dont think so. you could send it over the console

[quiet ice]

Bukkit should have a doPrivilegedCommand or something tbh

[violet niche]

I don't need the original sender, so... hopeful

[hybrid spoke]

Bukkit#dispatchCommand should it be

[sacred vector]

    @EventHandler
    void onBeaconPlace(BlockPlaceEvent event){
        if(event.getItemInHand().isSimilar(itemManager.megaBeacon)){
            event.setCancelled(true);
        }
    }
``` So like this?

[hybrid spoke]

most likely

[quiet ice]

wouldn't prevent plugins from checking it manually

[violet niche]

return Bukkit.dispatchCommand(Bukkit.getConsoleSender(), String.format("whitelist add %s", String.join(" ", args)));
```atm

let's see!

[quiet ice]

that can be done via bukkit api

[hybrid spoke]

why don't you use the bukkit api for that

[quaint mantle]

anyone know alternative way to write this for java 11 ```java
Bukkit.getScheduler().runTaskLater((Plugin)main, () -> {

}60L);```

[violet niche]

because this way is easier 😛

[quaint mantle]

With assignment crossbow in hand it isn't charged

ItemStack item = new ItemStack(Material.CROSSBOW)
CrossbowMeta meta = (CrossbowMeta) item.getItemMeta();
meta.addChargedProjectile(new ItemStack(Material.ARROW, 1));
meta.setCustomModelData(200);
item.setItemMeta(meta);
new BukkitRunnable() {
                        @Override
                        public void run() {
                            p.getInventory().setItemInMainHand(item);
                        }
                    }.runTaskLaterAsynchronously(Main.getInstance(), 1);

[violet niche]

I already have the working code using the bukkit api

[quaint mantle]

what is wrond?

[violet niche]

but it has funky error conditions

it forces me to UUID defaultUUID = UUID.nameUUIDFromBytes(("OfflinePlayer:"+playerName).getBytes(Charsets.UTF_8));

[quiet ice]

what is the issue there?

[hybrid spoke]

uhm, why don't you just get the offline player? EDIT: ah nvm, you don't have the UUID

[quaint mantle]

cant use lambas in java 11

[quiet ice]

You mean java 1.1, right?

[quaint mantle]

;D

[quiet ice]

Because java 11 def. supports it, check your target/source versions

[quaint mantle]

https://big-cock.club/mCU2Ogcf

Who da fuk uses Java 11 for MC?

[quiet ice]

that is not a lambda expression

[quiet ice]

J11 supports 1.13 - 1.17, so it is a good middle ground

[quaint mantle]

oh

[hybrid spoke]

you've left a , at the and. remove the run method

[quaint mantle]

but 1.17 doesn't support J11

[quiet ice]

not even then

[quaint mantle]

🤔i did not know this

[vapid thorn]

so the old way with cauldrons I just had to cast block data to Cauldron, but now with layered cauldrons how do I set that up now? I tried against block data and even state and both state I cant cast it for either

[quaint mantle]

hey?

[quiet ice]

Sure it does, Java is backwards compatible

[quaint mantle]

ahhh i see it works thanks

[quiet ice]

It wont work

[sacred vector]

is damage all like sharpness for a sword?

[quiet ice]

You have a half anonymous class - half lambda construct

[quaint mantle]

set item attribute

[vapid thorn]

DamageAll iirc is sharpness

[quiet ice]

a Java 16 JVM will in 99% of cases be able to load Java 11 plugins

[sacred vector]

i'm adding enchants not attributes atm

[violet niche]

So this works with the only downside being that the feedback is printed to the console instead of back to the player

which makes total sense

but bleghh

the api's just passing around a bunch of strings and I dont think I get to touch the permissions

[quiet ice]

why can't you just do Bukkit.getOfflinePlayer(String.join(" ", args)).setWhitelisted(true);? Or is there an issue with the UUIDs

[violet niche]

The alternative version is ```java
if (args.length == 1) {
String playerName = args[0];
UUID defaultUUID = UUID.nameUUIDFromBytes(("OfflinePlayer:"+playerName).getBytes(Charsets.UTF_8));
OfflinePlayer player = Bukkit.getOfflinePlayer(playerName);
if (!player.getUniqueId().equals(defaultUUID)) {
player.setWhitelisted(true);
sender.sendMessage(String.format("Could not find player "%s"", playerName));
return true;
}
sender.sendMessage(String.format("Could not find player "%s"", playerName));
}
return false;

But this has two problems

The UUID hackery sucks

[hybrid spoke]

because the method with getting an offline player by the name is contacting the mojang server

[violet niche]

and it's on the main thread so it freezes the game for a mo

[quiet ice]

why not check for hasJoinedBefore?

[hybrid spoke]

this could cause lags AND you could be banned if you have too many requests

[violet niche]

Because it's too late then

[hybrid spoke]

it will contact anyways

you need the uuid

[violet niche]

And I need players who havent joined before

[quiet ice]

mojang does not do that anymore

[hybrid spoke]

#getOfflinePlayer(String) will contact the mojang api no matter what. it needs to get the uuid.

[quiet ice]

At least unless you do that really frequently

[hybrid spoke]

as i said, at too many requests

[violet niche]

The CommandSender interface is interesting though

Can I extend it to have the isPermissionSet api return "yes"?

[quiet ice]

that is in the dozens of requests per second, if not more

Otherwise you could easily ban servers by just logging in a ton of offline-mode accounts

[violet niche]

This is still way simpler :/ ```java

    boolean isOp = sender.isOp();
    sender.setOp(true);
    boolean ret = Bukkit.dispatchCommand(sender, String.format("whitelist add %s", String.join(" ", args)));
    sender.setOp(isOp);
    return ret;

[hybrid spoke]

why do you argue against me if we are actually saying the same?

[quiet ice]

because it is not a concern

Well, wouldn't work

You still need the offline player instance to #setWhitelisted

[violet niche]

Well, ig I'll use this 😞 https://paste.md-5.net/xofisaguye.java

[vapid thorn]

is the cauldron api messed up or something? I cant even cast blockdata to Levelled anymore. (worked 1.16.5, trying to get working in 1.17)
guess im missing something.?

[hybrid spoke]

[violet niche]

It works 🤷‍♂️

[hybrid spoke]

but its a very bad and insecure practice

[quiet ice]

but very often used

[violet niche]

What vulnerabilities does it really create?

Bc if the only alternative is 10x as long for no real benefit then... I dont think I want to use it

[hybrid spoke]

you have the command sender

wait

what exactly are you trying to do

[quiet ice]

the real concern is that there is a chance of the programmer fucking up and resetting it, other other lesser concern is that anti-malware applications are going to flag the plugin

[violet niche]

basically alias my /welcome <player> command to /whitelist add <player>

The user should only need permission to call /welcome, /whitelist shouldnt matter

[quiet ice]

for a moment I wanted to suggest the commands.yml file, but that wont work

[vapid thorn]

while im aware of it, i even tried the new LayeredCauldronBlock and I couldnt get that to work, and its api setup appears to specifically target water, and there was a lava one as well. Im specifically trying to target a cauldron to see if its empty and then if its empty set its water level to full. I have a setup that uses dispensers with water buckets to fill, it worked in 1.16.5 and earlier but with new cauldron mechanics uhg xD

[hybrid spoke]

just get your offline player by the name.

in your case its not a big thing

[vapid thorn]

the layredCauldronBlock is extended off block data but then tells me it cant be casted to blockdata

so idk xD

[violet niche]

I need to write scheduling, reporting, unstable validation, and user feedback logic

It's not a huge amount of work, but it's far more complex than "call whitelist add"

[hybrid spoke]

basically 2 lines of code

[violet niche]

And doesn't represent what Im trying to do as well

[violet niche]

Oh? Nice! What would this involve?

[hybrid spoke]

well not even 2

[hybrid spoke]

the name of the player.
basically something like this: Bukkit.getOfflinePlayer(name).setWhitelisted(true);

[violet niche]

So...

I just explained why that's insufficient

If I want a command with the same utility as whitelist add, I need to write much more code

[quiet ice]

I already suggested that and you were the person to decline it

[eternal oxide]

why not just dispatchCommand with a ConsoleSender

[hybrid spoke]

yeah, but in his case it seems fine. its much more worse to just give the command sender op so he can execute the command

[violet niche]

I'd like to keep the feedback to the user of "who's that?" or "added so and so to the whitelist"

[violet niche]

But what harm does this do?

[quiet ice]

Plugins such as LP do not like OP iirc

No idea how they behave towards such code

[eternal oxide]

Then you use the returned boolean to tell them if it was successful or not.

[quiet ice]

I think that was already done but replaced due to some reason

[violet niche]

Yes, and I also would want to find a way to remove the output from the server console

[eternal oxide]

why?

[violet niche]

The command can also fail for other reasons

[eternal oxide]

The command will alwasy return a boolean. There is no other outcome

[violet niche]

I'd want to avoid putting the user message in the console because it doesn't belong there

[eternal oxide]

what user message?

[violet niche]

The other outcome is the command failing to parse

[eternal oxide]

you are defining the command it is impossible for it to not parse

[violet niche]

"That player does not exist" doesn't belong on the console

...

the command is defined by vanilla minecraft

[eternal oxide]

You seem to be making it harder than it actually is

[quiet ice]

You are misunderstanding each other

[violet niche]

Im happy with the simplicity of my impl

[eternal oxide]

You test if the player exists, if it does you issue the command

[violet niche]

I don't know why I'd make it more complex

[violet niche]

Right, but testing for the players existence is the complex part of this

[quiet ice]

The player will never exist though

[hybrid spoke]

1 method

[eternal oxide]

no its not, its very simple to test if a player exists

[violet niche]

Lol

[eternal oxide]

If you are only allowing players who have been on the server you can simply getOfflinePlayers() and see if yoru player is in there.

if you want ANY valid player, getOfflinePlayer, get teh UUID, then get again using the players UUID checking name for null, or compare their returned UUID to the offline generated one.

3 ways of doing it

[quiet ice]

Issue is NIO

[violet niche]

And all of them suffer from the same problem of blocking the thread they're running on

[quiet ice]

(though i'd argue NIO is involved there either way)

[violet niche]

And needing user feedback

and logging

[eternal oxide]

No only the get offlinePlayer by name blocks

[violet niche]

I'm not going to keep talking about this. Thankyou for your time

[eternal oxide]

every other method is non blocking

[hybrid spoke]

let him do his thing

we tried our best

[sacred vector]

        meta.addAttributeModifier(Attribute.GENERIC_ARMOR_TOUGHNESS, 2);
``` Im getting a a underline on the 2, is this how u use a Modifier? 

If not just gimme the link to docs page..

yeah i see it now thanks

[vapid thorn]

im slowly beginning to hate cauldrons xD

lol

[sacred vector]

yeah no errors with this now

        AttributeModifier modifier = new AttributeModifier(UUID.randomUUID(), "generic.armor_toughness", 2, AttributeModifier.Operation.ADD_NUMBER, EquipmentSlot.HEAD);
        meta.addAttributeModifier(Attribute.GENERIC_ARMOR_TOUGHNESS, modifier);

[gaunt hatch]

Have anyone find a way to get around the refection final field problem in java 16?

[quaint mantle]

I have a problem, i want to import files, but idk it dosen`t work, it always gets red :c

thats real descriptive

[quaint mantle]

Hmm do you know how t import other of your files?

wtf are you even asking?

[quaint mantle]

Yes?

stop pinging me

[quaint mantle]

kk

[opal juniper]

Am i correct in saying that HashMap#getOrDefault will either get the value of the key or return the new default

[eternal oxide]

correct

[quaint mantle]

[opal juniper]

So if i had a
Map<String, Set<UUID>>
and i ran this:
getOrDefault(isoKey, new HashSet<>()).add(player.getUniqueId());
it would either add it to the existing key or it would add a new set and add the uuid?

[gaunt hatch]

getOrDefault does not add it a return

[eternal oxide]

add does not return a HashSet so no that would not work

[sacred vector]

So we have attributes and I now have them on my armor, but the armor bar can it go more then 10 like health? i want it to show 20 bars of armor because custom armor will each have higher then 10 but at different values

[opal juniper]

Why would i need add to return a hashset?

[gaunt hatch]

The idea behind getOrDefault is to return a value from a key or return something if its no there.

[opal juniper]

ohhh i get ya

[quaint mantle]

public static PluginDescriptionFile description = this.getDescription();
public static String version = description.getVersion();

here "this" says "cannot use this in a static context"
how do i get around this?

[sacred vector]

no possible way to edit that without mods

?

mhm....

[quaint mantle]

how do i import other files in a file?

[opal juniper]

cause i need to add to the set if it does not exist in the map already

[eternal oxide]

don't do the add on the same line

[quaint mantle]

how?

inside onEnable()?

[gaunt hatch]

Then you need a check for the key, if not found add it, then return it.

[opal juniper]

what so like:

Set<UUID> uuids = map.getOrDefault(isoKey, new HashSet<>());
uuids.add(player.getUniqueId());
map.put(isoKey, uuids);

as an example

[quaint mantle]

i dont think i can use this. under onEnable()

[gaunt hatch]

you dont have a check in there

[quaint mantle]

Helppp

[gaunt hatch]

You are just adding it every time

[eternal oxide]

yes, but I'm not certain you need to push back to the map, it shoudl not be a copy but a reference

[opal juniper]

ah - makes sense

[eternal oxide]

Test though

[opal juniper]

👍

[gaunt hatch]

Set<UUID> uuids = map.getOrDefault(isoKey, new HashSet<>());
        if (!uuids.contains(player.getUniqueId())) {
            uuids.add(player.getUniqueId());
            map.put(isoKey, uuids);
        }

Check if its not there add and update the map

[opal juniper]

but sets cannot contain duplicates

[eternal oxide]

correct

[opal juniper]

and for my usecase it is impossible

for there to be a duplicate

[gaunt hatch]

then you have to check that also

but that is what that does

you see how i have it checking the set to see if its not there then it adds it

its its there it will not add it and update it

[opal juniper]

im so confused what you are talking about

sets cannot contain duplicates

[eternal oxide]

just add. If its a new Set it will get added, if its not it will be added if its not there.

[opal juniper]

That was the plan

[gaunt hatch]

Also unless its a manager class you should not be access a map with a direct call.

[opal juniper]

what

although that is a valid point

it seems a bit like you are spouting random knowledge to try and prove yourself?? 🙃

[gaunt hatch]

the 'map' object should not be access from a direct call from somewhere lese

No i am trying to help, with better code practices

[opal juniper]

Fair enough

but this is just a variable

not a field

[gaunt hatch]

yes how is it delcared?

public static Map<String, Set<UUID> map = new HashMap<>();

Maybe like this?

[opal juniper]

just like this

Map<String, Set<UUID>> targetPlayerLanguages = new HashMap<>();

cause it is a variable

[gaunt hatch]

and do you access it from outside of the class it is defined in with a direct call?

[opal juniper]

do you know what a variable is

in java

[vital swift]

bump

[opal juniper]

They are typically the ones which are part of a method

[gaunt hatch]

correct

ugh nvm

trying to help with better code practices, do it not the best way

[opal juniper]

sorry i made a typo

fields are part of a class

variables are part of methods

do you see what i mean now

[gaunt hatch]

you mean local variables

[opal juniper]

yuhuh

that is the same thing

[gaunt hatch]

no its not

[opal juniper]

kinda is but we should just move on

[gaunt hatch]

there are 3 types of variable

local
instance
static

[unreal quartz]

and where does it print null??

[vital swift]

in other plugin

[unreal quartz]

yeah

how do you get it though

[vital swift]

i use skript plugin to broadcast player's balance

just to debug

[gaunt hatch]

local - in side the method
instance - inside the class
static - global

[unreal quartz]

Bukkit.broadcastMessage("Double: " + i); doesn't look like skript to me

[vital swift]

no i mean the null

    broadcast "%balance of player%"```

this is the skript

[opal juniper]

he means he is accessing the api with skript

and that code is the api

[unreal quartz]

try writing a plugin to access it instead? don't think many people here know how skript works

for all we know it could be skript that is broken

[vital swift]

and other plugins

i have auction house plugin

and when i have 10000 coins i cant buy stuff for 1 coin

[opal juniper]

does this broadcast null @vital swift

[vital swift]

no it doesn't

[unreal quartz]

that won't broadcast null

[opal juniper]

just checkin

then yea - its probs a skript thing

[quaint mantle]

Arenas:
  Map2: {}
  Map1: {}``` How come I can't get the sections under Arenas with this: https://paste.md-5.net/xubakorizu.cs ?

[vital swift]

how about the auction house plugin

[opal juniper]

🤷

[unreal quartz]

could be your plugin is loading (and registering its economy provider) after other plugins get the economy provider

so to other plugins it appears as null

[unreal quartz]

you want this instead https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/MemorySection.html#getConfigurationSection(java.lang.String)

and https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/ConfigurationSection.html#getKeys(boolean)

[quaint mantle]

Main.java

import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
  PluginDescriptionFile description = this.getDescription();
  String version = description.getVersion();
}

this works fine, but how do i pass it to the below?

CMD.java

sendMessage(String.valueOf(Main.version)

[unreal quartz]

pass whatever you need in the constructor of CMD and store it in a field

in this case you can pass the version string, or the plugin instance itself if you want to do more with it

[true perch]

17.06 09:54:01 [Server] INFO Caused by: java.lang.UnsupportedClassVersionError: me/combatborn/firstplugin/FirstPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Am I getting this error because I'm using SDK 11.0.4?

[unreal quartz]

yes

[true perch]

Which version should I use?

[unreal quartz]

your runtime is java 8, your compiuled classes are 11

choose one

[true perch]

What do you recommend?

[unreal quartz]

everybody would recommend the latest version for obvious reasons

[true perch]

I've been learning java for the last few months, thought I'd give minecraft plugins a try

souns good, thanks for the help

[unreal quartz]

but some servers still run java 8, some java 11, though with mincraft 1.17 java 16 is required

[summer scroll]

Does anyone know why If I logout and have armor stand as a passengers, the helmet won't get removed.

[unreal quartz]

just depends who you're targeting

[vital swift]

ill see

but i don't haev other economy plugins

like essentials

[true perch]

I'd like to do a 1.17 server yeah

[summer scroll]

This is the method that I used when player logged out https://paste.md-5.net/ritaralivo.cs

[true perch]

Would this be recommended for 1.17? Java SE Development Kit 16.0.1

[unreal quartz]

if you're using 1.17 then you can use any version up to 16

[unreal quartz]

seems fine to me? is it just the helmet that isn't being removed

[quaint mantle]

Hey,

Is it possible to disable portals?

I want players to create them, but not use them

[unreal quartz]

cancel the event

[summer scroll]

The helmet isn't being removed.

That's why it has flying object.

[quaint mantle]

I cancelled EntityPortalEvent and PlayerPortalEvent without effect

[unreal quartz]

what version of spigot is it

[quaint mantle]

1.16.5

[unreal quartz]

is it registered? or you can listen to the teleport event or the switch wordld event, one or both has a cause you can check

[quaint mantle]

They are registered, yes

[summer scroll]

@unreal quartz or it's because I add equipment lock to the armor stand?

I add these on armor stand spawn

armorStand.addEquipmentLock(EquipmentSlot.HEAD, ArmorStand.LockType.ADDING);
armorStand.addEquipmentLock(EquipmentSlot.HEAD, ArmorStand.LockType.ADDING_OR_CHANGING);
armorStand.addEquipmentLock(EquipmentSlot.HEAD, ArmorStand.LockType.REMOVING_OR_CHANGING);

[quaint mantle]

PlayerChangedWorldEvent can't be cancelled... I also tried the PlayerTeleportEvent

[unreal quartz]

can try removing the equipment lock before removing the helmet

[summer scroll]

ah true, will try that

nvm, still the same

the helmet doesn't got removed

[unreal quartz]

don't see any other reason why none of your approaches work except for the fact that it might not be registered then

[quaint mantle]

It definitely is registered:
Bukkit.getPluginManager().registerEvents(this, this);

My events are in my main class.

There isn't even any console output... (Tried to print out some messages)
https://www.youtube.com/watch?v=Y60lp-XPlpY

[unreal quartz]

send your code

[summer scroll]

show whole class maybe

[quaint mantle]

https://paste.ofcode.org/wDSEfPMWQJ7yxPXimywKYA

[unreal quartz]

is the plugin even running?

[quaint mantle]

Yes 😅

[summer scroll]

The armor stand doesn't even got removed I think.

[unreal quartz]

is it even iterating over anything from player.getPassengers()?

could be that they get dismounted prior to the event being called

[summer scroll]

Okay, I'm gonna debug it. But what should I do if the entity got ejected before the PlayerQuitEvent got called?

[unreal quartz]

keep track of them somehow

[summer scroll]

And yeah, the entity got rejected before the event gets called.

What about store it on the map Map<Player, Entity>?

Anyways, thank you for that, i'm gonna sleep for now.

[unreal quartz]

could do that, or by UUID, UUID if you don't want to keep hard references

[summer scroll]

Yeah I think UUID fine, I don't really need Player object.

[opal juniper]

your class is final

maybe remove that

[quaint mantle]

Does somone know, how to upload maps in spigot server? xd

[unreal quartz]

the final wouldnt affect things

[unreal quartz]

drag the zip folder over ?

[quaint mantle]

Never had any problems with that, but ok, I'll remove it

[opal juniper]

and also - put a debug sys out in onEnable

[quaint mantle]

Tyyy and where do i have to put it?

[unreal quartz]

just in teh base directory

and unzip it

[opal juniper]

do you mean the picture maps or world maps 🙃

just checking

[quaint mantle]

Tyyy!!

[quaint mantle]

And do you know, how do i come to the map?

[unreal quartz]

use a plugin like multiverse to import it, or alter your server.properties to point to the new folder

[quaint mantle]

Thank you!!

[foggy bough]

quick question what does ambeint mean? java p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, duration, amplifier, ambient))

[unreal quartz]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/potion/PotionEffect.html#<init>(org.bukkit.potion.PotionEffectType,int,int,boolean)

Makes potion effect produce more, translucent, particles.

[foggy bough]

ohhh ok and amplifier means that my speed will go faster right?

[narrow vessel]

yeah

[quaint mantle]

I added multiverse, do you know, how i come to the map? I only know from Pocket Edition /mw tp "Worldname" but here nothing works :c

[unreal quartz]

mvtp

[quaint mantle]

Tysm!!

I unpacked the zip, but there isn`t the map when i do /mv list

[unreal quartz]

u need to import it

first

[quaint mantle]

How do i import it? xd

[sage swift]

mvimport

player data in the world folder

[quaint mantle]

mv import ?

[sage swift]

mvimport

or mv import

[quaint mantle]

I have done this, have i to put in /mv import "name of the folder? Or what do i have to input there?" ?

[sage swift]

that's why each multiverse command has feedback when you run it

[quaint mantle]

Mhh it tells me, that that not seems like it is a world :c

[cinder fable]

signs dont work when i click them

i should be teleported to hunger games game but dont tp me

[quaint mantle]

you're not making a plugin, wrong channel

[shut trail]

hey , can someone tell me how to add multiple nms versions to plugin

[frosty tinsel]

Hello, is it possible to view the spigot mappings in the ide?

[unreal quartz]

multi module project if ur using maven/gradle

[frosty tinsel]

https://www.youtube.com/watch?v=qS1DLgOxqpw&t

[shut trail]

thnx i will check it out

nvm i did saw that video

@frosty tinsel how to do that with maven?

[frosty tinsel]

idk, I actually haven't seen that video

try to find it on google

[shut trail]

how to set it up?

[unreal quartz]

looks comprehensive enough https://www.spigotmc.org/threads/maven-nms-tutorial.347254/

[frosty tinsel]

Is it possible to have Mojang mappings for NMS and spigot mappings for Bukkit at once?

Since now, all spigot methods are obfuscated

[woeful crescent]

Hey, can anyone tell me if it matters which plugin instance I put for Bukkit.getScheduler().runTaskLater()?

[frosty tinsel]

The plugin, you execute this in

[woeful crescent]

You mean

I have to put the plugin instance it's executing from?

That's what I've been doing, but I was wondering if it really mattered

[frosty tinsel]

I think so, because then, the task is tied to your plugin.

[quiet ice]

yes it does because otherwise it may not unload properly

[true perch]

public class Test implements CommandExecutor {
    private SecondPlugin plugin;
    public Test(SecondPlugin plugin){
        this.plugin = plugin;
        plugin.getCommand("test").setExecutor(this);
    }
    @Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        if (!(commandSender instanceof Player)){
            commandSender.sendMessage("Only players may execute this command.");
            return true;
        }else{
            Player p = (Player)commandSender;
            if (p.hasPermission(("test.use"))){
                p.sendMessage("Hello there, this is a test.");
                return true;
            }else{
                p.sendMessage(p.getDisplayName()+" does not have permission to send this command!");
            }
            return false;
        }
    }
}``` 
In the constructor I have the line: ``plugin.getCommand("test").setExecutor(this);``.
When hovering over the "setExecutor" method, it's producing this warning: ``Method invocation 'setExecutor' may produce 'NullPointerException'``
Why is that? Should I be concerned?

[shut oyster]

Because it isnt certain the command actually exist.

[novel lodge]

How can I make it so only the localName of an item matters in a crafting recipe?

[true perch]

I added this: yml commands: test: description: This is a test command.to the plugin.yml file. Is there anything else I can do to make sure it knows the command exists?

[sage swift]

the ide isn't aware of that

but you should be fine

[shut oyster]

as long as you register it correctly you can just ignore it yes

[true perch]

okay cool! good to know thank you

what do you want to do

[next zinc]

I want to heal the player by 50%

[mortal hare]

maybe you're diving by 0

Division by zero can make weird things like 1=2 in math

in that case programming languages forbid you from doing that

could someone help me debug my plugin, it should be working fine but i have no idea whats going wrong, ( its a simple chest cleaner plugin, i also have the code that works fine, but when i try the same for others blocks like barrels, it dont work )

[unreal quartz]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply.

[quaint mantle]

this works for "chunk" but not for "world" or "server"

if (Blockname.equalsIgnoreCase("Barrel") && blockState instanceof Barrel) {
            Barrel barrel = (Barrel)blockState;
            barrel.getInventory().clear();
        }
        else if (Blockname.equalsIgnoreCase("BlastFurnace") && blockState instanceof BlastFurnace) {
            BlastFurnace blastfurnace = (BlastFurnace)blockState;
            blastfurnace.getInventory().clear();
        }
        else if (Blockname.equalsIgnoreCase("Chest") && blockState instanceof Chest) {
            Chest chest = (Chest)blockState;
            chest.getInventory().clear();
        }
        else if (Blockname.equalsIgnoreCase("Dispenser") && blockState instanceof Dispenser) {
            Dispenser dispenser = (Dispenser)blockState;
            dispenser.getInventory().clear();
        }
        else if (Blockname.equalsIgnoreCase("Dropper") && blockState instanceof Dropper) {
            Dropper dropper = (Dropper)blockState;
            dropper.getInventory().clear();
        }
        else if (Blockname.equalsIgnoreCase("Furnace") && blockState instanceof Furnace) {
            Furnace furnace = (Furnace)blockState;
            furnace.getInventory().clear();
        }
        else if (Blockname.equalsIgnoreCase("Hopper") && blockState instanceof Hopper) {
            Hopper hopper = (Hopper)blockState;
            hopper.getInventory().clear();
        }

original, this works fine but it only supports "chest"

if (blockState instanceof Chest) {
        Chest chest = (Chest)blockState;
        chest.getInventory().clear();
      }

[unreal quartz]

this works for "chunk" but not for "world" or "server"
?

[quaint mantle]

trying the above one for "world" or "server" gives an internal error

[unreal quartz]

you can also just cast to InventoryHolder rather than checking for each one

[quaint mantle]

basically you can reset the supported blocks, within your chunk or world or server

[true perch]

Is there an existing method that's better for sending a message to all online players other than doing this:

ArrayList<Player> players = new ArrayList<>(plugin.getServer().getOnlinePlayers());
for (Player player : players) {
    player.sendMessage("The console has sent you a message.");
}```

[unreal quartz]

why are you creating a new array list?

[true perch]

loop through them all to send a message

[unreal quartz]

also you can just use Bukkit.broadcastMessage

[true perch]

ah thanks

[unreal quartz]

yeah but you don't need to create a whole new array list

for (Player player : plugin.getServer().getOnlinePlayers())

[true perch]

thats good too

            return;

[unreal quartz]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/Bed.html doesn't appear to be

[shadow gazelle]

Maybe because it's a persistent data holder?

[quaint mantle]

Can you show me an example? Please

[unreal quartz]

this method provides the console command sender https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Server.html#getConsoleSender()

pass the returned value of that into the first one

[shadow gazelle]

It's easy to fix, anyway ¯_(ツ)_/¯

How to make an inscription in front of a nickname? Is it in the documentation or not?

[quaint mantle]

Oh thanks

[ebon siren]

how would i check if a player died to a sword or a bow, i understand that i use PlayerDeathEvents and their last cause but how would i get the item they were killed with

[unreal quartz]

you can check the killers held item for a sword, for a bow you need to track each arrow as their are shot to their bow, i don't think there is a simple way to get the bow which shot an arrow

[ebon siren]

alright, thanks

and more question: how would i check if the player's killer was an entity or a player type, i know instanceof exists but player and entity are abstract so it doesn't exactly work

[mortal hare]

do you guys throw IllegalArgumentException when the arguments specified in the function are invalid? If so, why? Doesn't the runtime throw nullpointerexception, and doesnt make the code more heavy just because you add one unneccesary if statement?

[lean gull]

anyone know how to use all the dust particle stuff? like options, transition and normal?

spigot api doesn't have examples

[unreal quartz]

what if the passed argument isn't null but say, for instance, out of range? then what

if you're writing a method for someone else to use, then throwing an exception with a short message telling them how they fucked up is generally a good idea

[mortal hare]

maybe you're right

[unreal quartz]

it is also much safer to check the arguments and throw an exception than let the code execute with bad parameters as the code relying on that data could be safety critical and potentially cause damage with bad data

[ivory sleet]

yeah

for instance if u spawn a redstone particle u can choose to pass new Particle.DustOptions(color,size) through the data parameter iirc

or smtng like that

[quaint mantle]

does binding a socket freeze the main thread?

[ivory sleet]

its probably call sensitive

[quaint mantle]

ah nvm its serversocket#accept

makes sense

So I made a custom item , but people can use it anywhere on the server .
any tips

[pine zephyr]

Alright, I need help with my multi java versions due to 1.17.

So My project Holograms (https://github.com/wherkamp/Holograms/tree/new_mc)

However I cant compile it. Because The 1.17 module needs to use Java 16
Because it fails and says
class file has wrong version 60.0, should be 55.0

If I set it to Java 16
Gradle Says

ublic class EntityNameable extends EntityArmorStand implements Nameable {
       ^
  bad class file: /home/wherkamp/.m2/repository/org/spigotmc/spigot/1.17-R0.1-SNAPSHOT/spigot-1.17-R0.1-SNAPSHOT.jar(/net/minecraft/world/INamableTileEntity.class)
    class file has wrong version 60.0, should be 55.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.
2 errors```

My guess is to have Gradle do two releases one with 1.17 Java 16 and one without.

But I am not sure how to do that. And if that is the best idea

[chrome beacon]

Looks like you're not using Java 16

[pine zephyr]

I dont want to use Java 16. Because I want to keep older support

[chrome beacon]

You need Java 16 if you want to use NMS

[pine zephyr]

My user base is mostly 1.16 and non of them use Java 16. So I want to push it a bit longer before forcing an update

[chrome beacon]

You might be able to work around this by using a module that you shade in

[pine zephyr]

Thats what I am doing. The 1.17 is shaded in.

[shut field]

can someone please explain to me how to use LootContext?

[chrome beacon]

Yeah you need to compile the module with Java 16

Wait a min

Yeah I'm not sure

[pine zephyr]

https://paste.ee/p/5LG5J

[eternal oxide]

Yes MC 1.17 requires Java 16, No alternative

[pine zephyr]

If I set the 1.17 module to java 16 this happens

[eternal oxide]

Yeah, you are still forcing java 8 compat

[pine zephyr]

I need to set the entire project to 16

java {
    withJavadocJar()
    withSourcesJar()
    targetCompatibility = org.gradle.api.JavaVersion.VERSION_16
    sourceCompatibility = org.gradle.api.JavaVersion.VERSION_16
}```

I just did that to the specific module

[dusk flicker]

well fist of all you dont need the else

you are returning inside the first if statement, so no matter what it wont execute past that if that condition is met

[chrome beacon]

Just make everything Java 16 it will make your life easier

The major versions will support this

[dusk flicker]

I've never seen the Inventory#setContents used before, ill take a look at the javadocs for it but if you can send your entire class that would be useful/

[undone axle]

BungeeCord Chat: https://javadoc.io/doc/net.md-5/bungeecord-chat/latest/index.html

[pine zephyr]

That will drop support for the old versions. But ok

[chrome beacon]

1.8.8, 1.12.2 and 1.17 the major versions all run fine on Java 16

[pine zephyr]

But it will require them to update their server platform

[chrome beacon]

Yeah they will have to deal with that

Don't make it too hard for yourself

[dusk flicker]

at this point most services will be running J16 for minecraft as its required for 17

[chrome beacon]

^^

And the illegal access permit does fix most broken plugins with Java 16

[shut field]

what location does LootContext.Builder() need?

[dusk flicker]

Check the javadocs

[pine zephyr]

I think I am just going to keep a branch open with older versions for a bit of LTS. and a main branch will be 1.17 + and Java 16 so I can use all the fun nice features

[chrome beacon]

The location that the loot should use

[shut field]

I always check the javadocs before asking a question here, it just does not give the answer

[dusk flicker]

Olivo answered you, and that does answer your question.

[chrome beacon]

Look closer

[shut field]

what is it using that location for though

[chrome beacon]

It's where the chest, mob etc is located I assume

The loot does spawn somewhere

[dusk flicker]

Its where the loot will generate

https://cdn.rackdevelopment.tech/img/GNnL2QuEOE.png

Took me a few seconds to find that in the Javadocs, you will have to look closer.

[shut field]

where did you find that

[chrome beacon]

Javadocs

;/

[shut field]

I am ON the javadocs

I always keep it open while I'm coding

[dusk flicker]

So Builder is a builder for the 'LootContext' class, so I looked into the actual LootContext class for the getter of 'Location'.

[chrome beacon]

Then try reading it

;/

[dusk flicker]

this is basic java and javadoc understanding

[opal juniper]

I need to make api requests but I need them to be as fast as possible - anyone got any tips

[quaint mantle]

Imagine having the Javadocs open and not even reading them smh

[dusk flicker]

Id use something like redis but it really depends per application

[opal juniper]

I just essentially need it to be as fast as possible

It needs to translate things the player inputs in real-time

So request to a translation api

[violet niche]

You're going to struggle to do that without client mods

But if you need it, the best thing you can optimise is the location the server is running

so that it can make direct requests to the translation service

some cloud providers will give you much more negligible latency on the requests

[opal juniper]

Yeah - i have no doubt that a lot of the bottle neck is the actual packets getting from a -> b

so i am just trying to minimise as much as possible of my latency 🙃

[violet niche]

I'm not familiar with the libraries you'd use in java, but a big way to lower latency on frequent requests would be reeping the http connection open

so youll need a http library capable of that

[opal juniper]

Yeah - the thing is that on average the same request is about 30% faster on python

So 🤷

[dusk flicker]

Id recommend you use Redis

It's insanely fast

[ivory sleet]

just make addEnchant public

Im making a shaped recipe and was wondering how you would have a custom item as an item in the recipe. //Shaped Recipe ShapedRecipe shapedRecipe = new ShapedRecipe(NamespacedKey.minecraft("flamethrower_recipe"), item); shapedRecipe.shape("PGP","PFP","PLP"); shapedRecipe.setIngredient('P', ironPlate); shapedRecipe.setIngredient('G', Material.GOLD_INGOT); shapedRecipe.setIngredient('F', Material.FLINT); shapedRecipe.setIngredient('L', Material.LAVA_BUCKET); Bukkit.getServer().addRecipe(shapedRecipe);
IronPlate being the custom recipe

i've tried without it, doesnt work still

[true perch]

Is it something to do with Spigot 1.17?

[quiet hearth]

I added that and rebuilt the jar and ran it in my server and when i go to put the plates in the places it does not work, but i can craft the item as if they were not part of the recipe

Reflection is not usable in java 16 for internal methods

[quiet ice]

what the hell are you doing here

[crude axle]

How do I fix it?

[quiet ice]

Impossible

It has been always convention to not poke at JVM internals, now it is a rule

Well, it has been for a few years now (since august 2017)

[crude axle]

Except I am unable to find any classes that reflect Java internals in that module.

[eternal oxide]

Is yoru IDE not updated? Eclipse?

[crude axle]

IDE is IntelliJ IDEA 2020.2.3

[pine zephyr]

In Minecraft 1.17 where is the registerEntity method inside the WorldServer class

[lean gull]

anyone know why this is happening?
https://i.imgur.com/uf9yNW4.png
i just made a new paper server with a new plugin like i did twice before (following a tutorial) but this time this happens?

the only change i made was instead of making a 1.16.5 server i made a 1.17 server

[eternal oxide]

1.17 on a 1.16.5 jar

[crude axle]

So should I update the IDE?

[eternal oxide]

Sorry I don't use that IDE

[lean gull]

elgal i clicked show message cause i was bored and you do realize you're blocked in my account, right? (don't bother answering, i won't click show message again)

[digital rain]

for some reason it doesnt recognize addprimeenchant from the other class, yeah im quite new to coding, anyone can help?

[eternal oxide]

I answer to whoever asks for help, If you are too much of a prick to accept help, thats upto you

[digital rain]

no elgarl is cool

[eternal oxide]

Have you registered the command/executor in yoru onEnable?

[lean gull]

ohh it says unsupported api version 1.17

that's hella dumb

[true perch]

Why does this crash the server? java Inventory gui = Bukkit.createInventory(player,9,"Custom GUI"); player.openInventory(gui); Crash report: https://hastebin.com/qiqukuwajo.apache

It crashes regardless of if I add an item to the gui object like so: java ItemStack gameItem = new ItemStack(Material.DIAMOND_AXE); ItemMeta gameItemMeta = gameItem.getItemMeta(); gameItemMeta.setUnbreakable(true); gameItemMeta.setCustomModelData(101); gameItem.setItemMeta(gameItemMeta); gui.addItem(gameItem);Does anyone know another solution or know how to fix this?

[digital rain]

yes

[eternal oxide]

do you have the command correctly in your plugin.yml?

[digital rain]

yes

this is the addprimeenchant function

[quiet ice]

Do you get the same issue with the standalone maven? If yes, then it is something with your buildscript, not your IDE

[eternal oxide]

You need to run BuildTools again. Your Spigot is out of date and bugged IndexOutOfBoundsException: Index 0 out of bounds for length 0

[quiet ice]

I recommend recompiling with the --stacktrace (I think that was it) flag, I highly doubt that your IDE is at fault here

[eternal oxide]

When you use the command is the command recognised?

[digital rain]

yes the command is all good just the addprimeenchant is unrecognized in the class

[quaint mantle]

ok so I'm trying to cancel players from damaging them selves through arrows and harming potions

but how can I check the shooter of such potions/arrows

[eternal oxide]

It looks like you are not adding the meta back to the item

[digital rain]

oh yeah true

[eternal oxide]

EntityDamageByEntityEvent and cancel the event if the attacking entity is an arrow

you test teh Entity instanceof Projectile. If it is, cast to Projection and use .getShooter()

[mortal hare]

You guys literally need to try maven with sublime text 4 and java language server

its basically an eclipse but way more efficient

on resources

no lag whatsover

it uses the same language server as Eclipse do

[eternal oxide]

No lag here on Eclipse

[mortal hare]

its even more smoother on ST4 since its written in CPP and has hardware acceleration support

it supports maven, stub generation, auto imports

its feels like VSCode but way faster and more aproppiate for java

[eternal oxide]

I liked VSCode before it became VSCode. Back when it was for VB8

[digital rain]

oh yeah i fixed it by changing void method => itemstack, anyways ty for the help

[eternal oxide]

np

[true perch]

When I attempt to run BuildTools.jar, the command prompt appears titled C:\Prorgram Files\Java\jk1.8.0_281\bin\java.exe for a split second and nothing happens. Any fix?

[mortal hare]

try running java -jar BuildTools.jar inside cmd

[true perch]

okay

[quaint mantle]

       if(e.getDamager() instanceof Projectile){
            Projectile projectile = (Projectile) e.getDamager();
            if(projectile.getShooter() instanceof Player){
                Player shooter = (Player) projectile.getShooter();
                if(shooter == e.getEntity()){
                    e.setCancelled(true);
                    return;
                }
            }
        }``` something like this

[eternal oxide]

If you are looking to use 1.17 MC you are going to need to install Java 16

[mortal hare]

yea.. And i still don't understand why archlinux doesnt have java 16 inside their official repo, now i need to use AUR's to install it

[eternal oxide]

yep

[quaint mantle]

But a damage potion isn't a projectile when it attacks the player, right.

[eternal oxide]

however, use .equals not ==

[chrome beacon]

They only have lts versions right?

[quaint mantle]

alright

[mortal hare]

not sure

[chrome beacon]

I think that's the case

Try installing a non-lts version and see if it can find it

[eternal oxide]

You have 3 events for potions Splash, Lingering and effect

use whatever you need

[quaint mantle]

but can I get the shooter of a splash

[mortal hare]

wait

they added it

no way

they literally added couple days ago to the repo

nice

that's not the case then

[eternal oxide]

getEntity() returns the Potion, which is also a projection, so you should be abel to cast and getShooter()

[quaint mantle]

ah coolio

[chrome beacon]

ah nice

[mortal hare]

yep

[quaint mantle]

couldn't I just use the damage event instead of a splash event that way

[mortal hare]

found the non headless version too

[chrome beacon]

Sorry for the repeat pings ;/

[eternal oxide]

I don;t believe a splash potion would trigger that event

as it has its own

[quaint mantle]

but the potion is an entity right

[eternal oxide]

yes

but its not the entity thats actually causing the damage

its the effect

[smoky anchor]

Hi, how does one check if block contains liquid. Block.isLiquid() checks if it is water or lava and the Waterlogged interface does not work on seagrass.

[eternal oxide]

isWaterlogged is for flooded blocks like corals and fenceposts/stairs. It should work for seagrass, unless its been forgotten

[smoky anchor]

well seagrass is not waterlogged as it can not be without water

[chrome beacon]

Yeah was about to say

It has to be in water

[eternal oxide]

if it can't be without water isn't it a superfluous test to see if it has water?

[quaint mantle]

    @EventHandler
    public void onSplash(PotionSplashEvent e){
        Potion potion = (Potion) e.getPotion();
        if(potion.getType() == PotionType.INSTANT_DAMAGE){
            Projectile projectile = e.getEntity();
            if(projectile.getShooter() instanceof Player){
                Player shooter = (Player) projectile.getShooter();
                e.getAffectedEntities().remove(shooter);
            }
        }
    }```

[quiet hearth]

How does one change the dye color of a piece of leather armor

[smoky anchor]

I was wondering if there is like one function that checks if there is liquid in this position or not.

[chrome beacon]

Use LeatherArmorMeta https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/LeatherArmorMeta.html

[eternal oxide]

Shoudl work. You may want to check the type of potion as you probably want to be able to use positive effect ones.

[hallow escarp]

Hello! I am trying to make a falling block to drop random materials on the world.
I have this code, but the falling block doesnt appear or fall.

Location pos = new Location(p.getWorld(), p.getLocation().getX(), p.getLocation().getY() + 50, p.getLocation().getY());
          FallingBlock fallingBlock = p.getWorld().spawnFallingBlock(pos, Material.OAK_LOG, (byte)0);```
p is the player variable by the way.

[eternal oxide]

I'm not sure what you mean, if its seagrass its seagrass. Are you wanting to test when its placed or something?

[quaint mantle]

4th line checks if it's INSTANT_DAMAGe

[eternal oxide]

k

[hallow escarp]

It works if i spawn the falling block right on the player

aka replacing pos with p.getLocation()

I also tried teleporting the player to pos, and it worked fine so it has nothing to do with pos

[eternal oxide]

Location pos = p.getLocation().clone().add(0,50,0);

[hallow escarp]

Thats odd because I was able to tp to it

Without any issues

[quaint mantle]

Caused by: java.lang.ClassCastException: org.bukkit.craftbukkit.v1_8_R3.entity.CraftThrownPotion cannot be cast to org.bukkit.potion.Potion
when i do Potion potion = (Potion) e.getPotion();

[hallow escarp]

Ill try this though

[eternal oxide]

Just showing a simpler way to create the location

[hallow escarp]

ah

[eternal oxide]

ThrownPotion

[quaint mantle]

replaced it with java ThrownPotion potion = e.getPotion(); if(potion.getEffects().contains(PotionType.INSTANT_DAMAGE)){

[eternal oxide]

are you using 1.8? If not you shoudl really use one of the non deprecated methods

[hallow escarp]

No, I am using 1.17

[smoky anchor]

NMS Mojmap LevelChunk#getFluidState(BlockPos) returns the Fluid state. Meaning if there is any kind of liquid (either waterlogged, forced water like seagrass or just regular water or nothing) it will return the state of that water. Is there any API function that does the same.
I do not care about what the block is I just want to know if there is water or not.

[next zinc]

?paste

[undone axle]

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

[eternal oxide]

if IsWaterlogged() doesn;t work you'd have to ask Choco

isWaterlogged shoudl be mapping that method

[next zinc]

Ok so whenever I make a player interact event I get a ton of errors mostly revolving around a NPE when I detect if the player has the correct item in their hand. However, I'm not sure exactly how to stop this.
https://paste.md-5.net/bomezepebi.cs

[smoky anchor]

It checks the blockstate, not fluid state

[quaint mantle]

item may not have itemmeta

[eternal oxide]

Lots of things in line 6 can be null. You need to test for an account for that

[next zinc]

I know that, but how exactly can I detect those things?

make like a check to see if the player is holding null and then cancel it or soemthing?

[eternal oxide]

every time you can get null, assign to a variable and test it

[next zinc]

If I did this would that just automatically make everything else not be detected?

if(!player.getInventory().getItemInMainHand().getItemMeta().getDisplayName().equals(ChatColor.DARK_GREEN + "Common Loot Box")) {
                event.setCancelled(true);
                return;
            }

[eternal oxide]

ItemStack item;
if ((item = player.getInventory().getItemInMainHand()).hasItemMeta())```

[next zinc]

ohh

I see

[eternal oxide]

you can then use item to do yoru other tests

[next zinc]

thats smart

ty

ill test it out

[hallow escarp]

Also, any way to make it slower?

[quaint mantle]

setting it's velocity

[hallow escarp]

Ive tried, instead of making it slower, it just instantly drops

[lean gull]

anyone know why this returns an error?
https://i.imgur.com/IyU1pNB.png

[eternal oxide]

yes

[sage swift]

lol

[hallow escarp]

or sometimes it doesnt even start dropping at all

[eternal oxide]

what are you setting a velocity?

[hallow escarp]

the falling block

[eternal oxide]

yes, what value are you setting?

[hallow escarp]

-1, -1, -1

[eternal oxide]

yeah, thats not going to be good

[hallow escarp]

why>

[eternal oxide]

thats is a vector with length of 1 in all directions

fast

[hallow escarp]

so is it the higher i go the slower?

or uh?

[eternal oxide]

try new Vector(0, -0.1, 0)

[hallow escarp]

alright

[true perch]

Just finished updating my java to 16, used build tools to get spigot-1.17.jar, and tested it out. It worked! Thanks ❤️

[hallow escarp]

its just instantly on the floor

it doesnt smoothly fall

just instantly goes on the floor

i dont know if it matters that im using a chest

[eternal oxide]

use a smaller value

[hallow escarp]

no matter what value i do it still does it

            Location pos = p.getLocation().clone().add(0,50,0);
            FallingBlock fallingBlock = p.getWorld().spawnFallingBlock(pos, Material.CHEST.createBlockData());
            fallingBlock.setVelocity(new Vector(0, -0.1, 0));````

here is my code

with the 0.1

figured out why

it has to do with the chest

for some reason chests cant be smoothly dropped

[eternal oxide]

try fallingBlock.setVelocity(fallingBlock.getVelocity().multiply(0.5))

does it have gravity enabled?

[hallow escarp]

i tried it with oak logs and it worked

[hallow escarp]

let me try enabling it

[hallow escarp]

enabled gravity, still not workin

[eternal oxide]

odd, but good to know chests are funky

[hallow escarp]

yeah lol

[hallow escarp]

this just makes the barrel megafast

[eternal oxide]

It should cut the velocity in half

[hallow escarp]

is there supposed to be a -0.5

or just 0.5

[eternal oxide]

just 0.5

[hallow escarp]

yeah it just makes it super fast

[eternal oxide]

[dusky spade]

ik this not bukkit server, but what sound from mc could I use to make a "ding" sound?

Can anyone help me to understand this code a bit more?

for (double t = 0; t < 50; t += 0.5) {

                    double x = radius * Math.cos(t);
                    double z = radius * Math.sin(t);

                    p.getWorld().spawnParticle(
                            Particle.REDSTONE, new Location(p.getWorld(), p.getLocation().getX() + x,
                                    p.getLocation().getY() + 1, p.getLocation().getZ() + z),
                            1, new Particle.DustOptions(Color.AQUA, 1));

                }

this code creates a circle
a circle
the thing is
iam fully aware how cos and sin work
i know that if you multiply hypothenus with math.cos(degrees) you will get the horizontal side of the triangle
and sin returns the vertical side of the triangle
the thing is
i cant understand how this is used to create a circle
the 0.5 i understand is how close the particles are to each other
but i dont understand why it is used as the degrees

I'm trying to add some flags to an item, this is what I have but I'm not sure how to initalize ItemFlag flag;

This is what I got so farjava ItemFlag flag; gameItemMeta.getItemFlags().add(flag);

[vital ridge]

flags are added with itemmeta

[true perch]

        ItemMeta gameItemMeta = gameItem.getItemMeta();```

[eternal oxide]

Using cos and sin its calculating points on a circle

[vital ridge]

On a circle?

Wbu the triangle tho

[true perch]

ItemStack gameItem = new ItemStack(Material.DIAMOND_AXE);
ItemMeta gameItemMeta = gameItem.getItemMeta();
gameItemMeta.setDisplayName("1");
gameItemMeta.setUnbreakable(true);
gameItemMeta.setCustomModelData(101);
ItemFlag flag;
gameItemMeta.getItemFlags().add(flag);
gameItem.setItemMeta(gameItemMeta);```
This is what I have for the itemstack so far, just not sure how to initialize the flag

[eternal oxide]

look up Pythagorean theorum and see where cos and sin are used on a angle of the hypotenuse.

https://cetking.com/pythagorean-theorem-circles/

[vital ridge]

thank you ill look into it

[eternal oxide]

not a good example though

[vital ridge]

anything helps tbh

[eternal oxide]

this is better https://www.dummies.com/education/math/trigonometry/pythagorean-sine-and-cosine-identities-on-a-unit-circle/

[lean gull]

anyone know why this isn't doing anything when i craft?
public void WaterTNTSound(CraftItemEvent event) {

uhhhh

imma just casually moonwalk outta here

[vital ridge]

instead of getitemflags.add, use gameItemMeta.addItemFlags(ItemFlag.(YOUR_ITEM_FLAG)

[true perch]

I wrote a quick method to remove Item Flags from an ItemMeta, but it doessn't seem to do anything java private ItemMeta hideAllFlags(ItemMeta itemMeta){ itemMeta.getItemFlags().add(ItemFlag.HIDE_UNBREAKABLE); itemMeta.getItemFlags().add(ItemFlag.HIDE_DYE); itemMeta.getItemFlags().add(ItemFlag.HIDE_ATTRIBUTES); itemMeta.getItemFlags().add(ItemFlag.HIDE_DESTROYS); itemMeta.getItemFlags().add(ItemFlag.HIDE_ENCHANTS); itemMeta.getItemFlags().add(ItemFlag.HIDE_PLACED_ON); itemMeta.getItemFlags().add(ItemFlag.HIDE_POTION_EFFECTS); return itemMeta; }

[vital ridge]

as i said, use itemMeta.additemflags

[true perch]

oo I'll do that

[minor vapor]

itemMeta.addItemFlags(ItemFlag.values());

much cleaner

[green comet]

is anyone in intellij idea rn

[true perch]

oh wow yeah that is very clean

[lean gull]

anyone know why sleep has a red line below it in both of these?
TimeUnit.SECONDS.sleep(1);
Thread.sleep(1000);

[true perch]

Hiding the flags works great, however now I'm stuck with sseeing this: https://prnt.sc/15qj6nc

[eternal oxide]

Never use sleep in main thread

[minor vapor]

If it's red, it's likely the IDE telling you to use a try and catch statement as those methods both throw IllegalArgumentException and InterruptedException

[minor vapor]

seeing what?

If you mean the dark gray text, that's client side

[true perch]

yeah

[minor vapor]

I believe anyways

[true perch]

oh right! debug mode

[lean gull]

i'm a beginner so i don't really understand, is there a simpler ways to wait a certain amount of time?

[crude axle]

Yes. This happens with standalone Maven too

[minor vapor]

The Bukkit scheduler: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scheduler/BukkitScheduler.html

[quiet ice]

Then this is almost certainly an outdated plugin or something

[minor vapor]

which is passed through the scheduler? lol

[crude axle]

Here is POM

[lean gull]

what do i do with that

[crude axle]

The three modules before that are successful

[granite stirrup]

u do stufff with it

[minor vapor]

see Bukkit#getScheduler()

[green comet]

does anyone here have intellij idea open?

[granite stirrup]

u probs have to use the runTaskLater method

i think

[quiet ice]

looks like it is as it should, I recommend running it with the stacktrace flag (or whatever it is for maven, I always forget) so we have an idea where it happens

[lean gull]

there's no getSchedular on that

[chrome crane]

does anyone know why its doing this? I opened the server file with git and i pasted this command: java -jar BuildTools.jar --rev 1.17

What version are you using?

If it's not a thing, try Bukkit#getServer()#getScheduler()

there is on class bukkit

you meant "no", correct?

[lean gull]

i'm talkin about the api

not in code

[minor vapor]

wdym not in code?

[lean gull]

i mean i'm looking at the spigot api rn

[minor vapor]

which has the Bukkit class?

?

i'm talking about this:

[minor vapor]

yes, what about it?

[lean gull]

you said that can help, but the information doesn't help me

[minor vapor]

You're trying to delay a task, correct?

[lean gull]

well i'm trying to delay a spawn particle within a for loop

share us your code and tell us where exactly the error is at

currently i have no errors since i'm not really doing anything

@lean gull has exactly what you're looking for

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scheduler/BukkitScheduler.html#runTaskLater(org.bukkit.plugin.Plugin,java.lang.Runnable,long) to be specific

[lean gull]

i have no clue how to use this

[granite stirrup]

bro

[minor vapor]

The docs explain it

please read them

[granite stirrup]

i think u do java Bukkit.getScheduler().runTaskLater(plugin,new Runnable() { @Override public void run() { // your code } },Ticks); i think

im not to sure

never used the scheduler myself

[vital ridge]

https://www.youtube.com/watch?v=T1_ikvAQHkM&t=4s

[tame coral]

You can either do this or pass a function instead of runnable :

Bukkit.getScheduler().runTaskLater(plugin, () -> {
// The code
},execute_x_ticks_after_this_is_called, execute_every_y_ticks);
