[rotund prawn]

can someone help?

[young knoll]

What do you mean it’s not banning them

[rotund prawn]

its not banning him

he vcan join back

and its not doing anyhting

when i trxy to do it

[proven coral]

i dont understand im using a command block not coding a plugin

[young knoll]

Ah

Well, #help-server

Also no, the plugin would have to support it as far as I know

[proven coral]

agh

[snow stratus]

Player#setBanned()

[rotund prawn]

whats that

doesnt work

[snow stratus]

Use .

Player.setBanned

[young knoll]

That’s not a thing, at least not in 1.18

[rotund prawn]

im using 1.16.5

is there a another way for 1.16.5?

[snow stratus]

Huh, it isn’t a thing, could’ve swore it was

[rotund prawn]

oh no problem

gtg dinner

[snow stratus]

hmm,

Bukkit.getBanList() 

only takes Type.NAME and Type.IP

You might be able to do something like

Bukkit.getServer().getBannedPlayers().add(Bukkit.getOfflinePlayer(player.getUniqueId()));
player.kickPlayer("You are banned");

Not sure if it'll work though

@rotund prawn

[unkempt peak]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/BanList.html#addBan(java.lang.String,java.lang.String,java.util.Date,java.lang.String)

[snow stratus]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/BanList.html#addBan(java.lang.String,java.lang.String,java.util.Date,java.lang.String)

@NotNull
String target,

and the only way to get the banlist is by doing

Bukkit.getBanList(Type.NAME)
or
Bukkit.getBanList(Type.IP)

Which is fine if the player is online since their name won't change.
If they're offline you're going to have to do a name lookup with Mojang's servers

[unkempt peak]

So what's the issue?

[snow stratus]

I guess nothing. idk why there's not a UUID Type

[unkempt peak]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerLoginEvent.html#getAddress()

Just use that

The api has a method for getting ips

[snow stratus]

That's fine if you want to IP ban someone

[young knoll]

I think you might be able to stick the uuid in as a string and have it work

[unkempt peak]

Why wouldn't you ip ban?

[young knoll]

Bans are weird

[young knoll]

Some people have siblings

[snow stratus]

Does an IP ban also player ban? Or can I pull out my phone hotspot and jump right back on with my same account?

[rotund prawn]

nope, doesnt work

[snow stratus]

Maybe, I've literally never tried playing with bans

[unkempt peak]

No you aren't given it a player

I'm pretty sure it would be IP only

[snow stratus]

You could always do old reliable
Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "ban " + player.getName() + " You are banned!");

There has to be a better way than passing a player name as the argument, but I'm loading into a Tarkov raid rn

[unkempt peak]

Not a fan of executing console commands in a plugin but maybe it would work

[rotund prawn]

getting errors

[snow stratus]

Same, but it works and I'm starting a raid

[rotund prawn]

doestn owrk

[snow stratus]

Bukkit, not Plugin

[rotund prawn]

oh

still doestn work

[young knoll]

You can easily make your own system using the login event and a file to save uuids

[sullen marlin]

The name ban list is the same as the uuid ban list

[snow stratus]

Yeah, but why reinvent the wheel when the ban file already does that

[sullen marlin]

The name is bad and predates uuids

Think of it as PLAYER

[rotund prawn]

still doestn work

[young knoll]

So shoving a uuid in as a string works

[snow stratus]

So the Argument* will take UUID and not name?

API is still Type.NAME

[unkempt peak]

Yeah you don't have to use spigot/minecrafts banning system

[young knoll]

Or do you need to shove the name in still

[sullen marlin]

Yes, should

[young knoll]

What’s spigots thoughts on duplicate stuff with better names

IE adding Type.UUID that just redirects to Type.NAME

[unkempt peak]

Or it would make alot more sense to rename Type.NAME to Type.PLAYER

[buoyant viper]

would be nice to be more descriptive in code

[buoyant viper]

player still seems vague enough to mean UUID or Name

[young knoll]

Renaming is a breaking change

[unkempt peak]

so its just Type.PLAYER and Type.IP

[young knoll]

Spigot avoids breaking changes

[sullen marlin]

Be the change you wish to see in the world

[unkempt peak]

Oh yeah

[buoyant viper]

ezpz PR

[young knoll]

Can’t tell if that’s an invite to PR a breaking change :p

[buoyant viper]

then make it not breaking

[snow stratus]

Just add another type that then calls NAME

[unkempt peak]

Or you know just add a ban method to the player class so you don't have to deal with all that

[snow stratus]

What if player is offline

[unkempt peak]

OfflinePlayer

ban method

[young knoll]

Yeah that’s another option

[foggy estuary]

does anyone know how to prevent the timer becoming negative i tried doing ```
Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {
public void run() {
countdown --; //Taking away 1 from countdown every 1 second

final Score score = plugin.o.getScore(ChatColor.of("#fe6f5e") + "Time Left:"); //Making a offline player called "Time:" with a green name and adding it to the scoreboard
score.setScore(countdown); //Making it so after "Time:" it displays the int countdown(So how long it has left in seconds.)
 
if(countdown == 0) {
     for(Player p : Bukkit.getOnlinePlayers()) {
    p.setScoreboard(Bukkit.getScoreboardManager().getNewScoreboard());

    
    if(countdown == -1) {
        countdown = countdown - countdown + 20;
        
            p.setScoreboard(Bukkit.getScoreboardManager().getNewScoreboard());
    }
     

    //plugin.getServer().getScheduler().cancelTasks(plugin);

     }
    ```

[young knoll]

If you don’t want to PR it, at least consider making a Jira issue

[buoyant viper]

looks good to me

[foggy estuary]

Im not sure what the problem is then.

[candid quail]

@foggy estuary if countdown is less than zero

[buoyant viper]

^

[foggy estuary]

i tried that

[candid quail]

Make sure it's actually called?

Triple checked the signs?

[foggy estuary]

            countdown = countdown - countdown + 20;
            
                p.setScoreboard(Bukkit.getScoreboardManager().getNewScoreboard());
        }```

is what i did

i can also do < 0

but it doesnt change it

[candid quail]

Change it to <=

[foggy estuary]

ok

[next zinc]

Anyone know how to detect if a player left clicks twice?

[rotund prawn]

@snow stratus found the problem. it was a nullpointerexpection

[candid quail]

@next zinc store a bool for first click second click, depends on what event

[next zinc]

Im using PlayerInteractEvent

[foggy estuary]

That works, though for some reason the countdown becomes x2 speed

[next zinc]

and Ill try that and see how it works

[woeful crescent]

hey guys, i tried to make a class configurationserializable, but it's not working very well

it gives a noclassdeffound error before i even load anything

[foggy estuary]

My countdown always counts twice as fast.
Thus, not 60, 59, 58 ... but 60, 58, 56.
It happens after i do this if(countdown <= 0) { countdown = countdown - countdown + 20; for(Player p : Bukkit.getOnlinePlayers()) { p.setScoreboard(Bukkit.getScoreboardManager().getNewScoreboard());

What have I done wrong?

[woeful crescent]

and the noclassdeffound error is for a class that does exist

and can be used

[ivory sleet]

what r u tryna do

also

maybe just post the entire snippet

[foggy estuary]

this

[ivory sleet]

and not just parts

[young knoll]

countdown -= 20 :p

[ivory sleet]

?paste btw

[undone axle]

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

[foggy estuary]

The other guy told me to do <= so i listened

[ivory sleet]

so you don't know for yourself what you're doing?

[foggy estuary]

No i needed help with that

[ivory sleet]

well

post the entire runnable code

[foggy estuary]

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

[wet breach]

in the check where you check if it is 0, is where you should be resetting it

you shouldn't be checking if it is -1 because you shouldn't be allowing it to get that far

[foggy estuary]

I know i changed it to 0 after

[wet breach]

countdown = countdown -= countdown + 20;
this is very redundant

using -= is the same as doing countdown = countdown - (number)

so you can just collapse that down into a single =

[young knoll]

countdown -= 20

[wet breach]

https://paste.md-5.net/kiwuzegifo.cs#L46
on this line, we don't need to check if it is less than 0. If you really want to check if it is less than zero it should be an error check because you only care if it hits 0

the error check if it runs means something went really wrong XD

anyways once it hits 0, at the end of everything you want to do on 0, should be where it resets the timer or whatever else

<= means if it is less than or equal to

since it is a loop we shouldn't have a scenario where 0 gets skipped and now at -1 unless again something went really wrong

[spiral light]

from what is this:

Trying to mark a block for PostProcessing @ MutableBlockPosition{x=380, y=0, z=327}, but this operation is not supported.

while generating structures like villages/swamphut/stronghold ?

[dense geyser]

Is there a way to freeze Bukkit.getServerId() so it doesn't change?

[buoyant viper]

store it somewhere that doesnt change 😎

[fleet imp]

is there an onChat event or some

[buoyant viper]

theres AsyncPlayerChatEvent

[fleet imp]

oh thx

[wet breach]

And SyncPlayerChatEvent

depends which you need

[opal juniper]

*PlayerChatEvent

[buoyant viper]

doesnt that actually wrap back around to the Async counterpart

[wet breach]

yes and no, it is for things that can't be async

[spiral light]

even then you can make them sync by running bukkitschedular ^^

[flint carbon]

    public void onInteract(PlayerInteractEvent e) {
        Player p = e.getPlayer();
        ItemStack item = new ItemStack(Material.PLAYER_HEAD);
        ItemMeta meta = item.getItemMeta();

        if (e.getAction().equals(Action.RIGHT_CLICK_AIR) || e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {

            if (p.getInventory().getItemInMainHand().equals(Material.PLAYER_HEAD)) {

                assert meta != null;
                if (meta.getDisplayName().contains("Infinity Gauntlet")) {

                    e.setCancelled(true);

                } else if (p.getInventory().getItemInOffHand().equals(Material.PLAYER_HEAD)) {
                    if (meta.getDisplayName().contains("Infinity Gauntlet")) {
                        e.setCancelled(true);
                    }
                }
            }
        }
    }
}```

Hey I am trying to deny player head placement of a specific item, but it says 

"'equals' between objects of inconvertible types 'ItemStack' and 'Material'"

I'm pretty new to Java so if my code looks bad, you know why

[wet breach]

not necessarily no

if something is sync in the implementation your async scheduler isn't going to magically make it async

[spiral light]

nono...
in asyncplayerchatevent
if you need to place blocks for example ... you can call a BukkitSchedular

[wet breach]

Ah ok

[slow oyster]

I have a bit of a dilemma, a while back I added this method as a PR https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Bukkit.html#craftItem(org.bukkit.inventory.ItemStack[],org.bukkit.World,org.bukkit.entity.Player) I use it to add autocrafting to my plugin, but I've ran into an issue when trying to do the autocrafting for offline players, since it obviously takes a Player instance and I don't have that whilst the player is Offline. The player instance is used to send a PrepareItemCraftEvent. I'm thinking I'm going to need another method that just crafts vanilla recipes without the PrepareItemCraftEvent

[wet breach]

You could make a fake player object

you don't need the object to make it appear they are online, you just need to construct enough of the player object to satisfy what you need 😛

[sullen marlin]

How can you craft offline players???

[little trail]

What's the format for a clickable link again

[wet breach]

however in terms of a PR, not sure why it would be a useful thing in the base code

[opal juniper]

2 wood, a player head, and an iron chestplate

[spiral light]

^^

[wet breach]

lmao

that is a good one

[slow oyster]

What do you mean by craft offline players? The original method crafts an item as if it were the player, I.e using their inventory, the PrepareItemCraftEvent manipulates the result for custom recipes etc. Obviously this isn't possible for an offline player.

[sullen marlin]

well how can you craft as an offline playert

and why

[slow oyster]

That's actually a good idea tbf, I did wonder about that, there will just be a shit load of empty methods

[wet breach]

of course, didn't say there won't be problems or anything just in terms of what the server cares about for a Player object it isn't hard to create one 😛

[unreal quartz]

and beware of any plugin which listens to the craft event and wants to do something with the player

[wet breach]

^

[slow oyster]

So my plugin allows you to create auto-crafting tables using chests above a crafting table as the ingredients, and you set your recipe in the table. It then runs even if the player is offline etc

[sullen marlin]

seems player is pointless in that scenario then

[slow oyster]

Apart from the PrepareItemCraftEvent

Which plugins use to create custom recipes

[sullen marlin]

wouldnt 'public static ItemStack craftItem(@NotNull ItemStack[] craftingMatrix)' be sufficient for you

[sullen marlin]

well that'll never work

[little trail]

.

[sullen marlin]

look at ComponentBuilder, should be obvious

[inland palm]

hey!

i run a server and new help

whats a good anti cheat?

[sullen marlin]

this is a development channel

[slow oyster]

Yeah exactly, it just sucks that I will lose the custom PrepareItemCraftEvent recipes that some plugins use. (It is possible to create Recipes properly if I remember though right?)

[inland palm]

oh

[sullen marlin]

yes there is addRecipe

[slow oyster]

Okay so if anyone complains I can just tell them to use the API correctly then 😄

the craftItem() method is probably going to work best then

[fleet imp]

how do i get the index of a char in a string

or, is there an event for using a cmd

[sullen marlin]

those questions seem unrelated, why do you say or

[little trail]

Sorry, didn't know that existed so no it wasn't obvious

[sullen marlin]

https://www.spigotmc.org/wiki/the-chat-component-api/

[candid quail]

@sullen marlin what would your recommendation be for replacing NMS for NBTTagCompound without reliance on PDC?

[fleet imp]

either i can use the chat event and see if the first char is a / or if there is a cmd event already

[little trail]

..what

[sullen marlin]

why

[quaint mantle]

use pdc

[little trail]

Why did you reply to me

[sullen marlin]

PlayerCommandPreprocessEvent

[candid quail]

PDC Doesn't stretch over to all the items I want use, I want to remove reliance upon NMS

[sullen marlin]

wat

every item has PDC

[quaint mantle]

what

[candid quail]

One sec might of had a brain fart

For like a month

[foggy estuary]

I can do that, but how do i just make it restart if i do /start again

make it restart countdown from 20 again

manually

[woeful crescent]

I know this isn't quite "spigot", but can anyone help me with a Jitse NPCLib issue? If an NPC is created while a player is offline, but then is shown for that player when they join, the NPC won't show with no error. link: https://github.com/JitseB/NPCLib

you can take a look at how it creates packets and stuff there if you're not familiar with it

[candid quail]

I've had a brain fart for a month

[little trail]

I can’t find anything about links in there

[fleet imp]

oh THX

[slow oyster]

Also @sullen marlin when I'm running CraftBukkit inside IntelliJ I always get a crash because Bukkit.getConsoleSender() returns null but is marked as @NotNull, changing it to Nullable fixes the issue for me 🤷‍♂️

I'm not sure why running in IntelliJ causes it to return Null though, but it also means that the Null check isn't needed if it's supposed to be NotNull 😄

[rapid quiver]

Is this the right place to ask for BossShopPro help?

Nope, probably best to ask on their GitHub. Can't seem to find a discord for them at a glance: https://github.com/Blackixx/BossShopPro/issues

[rapid quiver]

Okay thank you:)

[young knoll]

This is a beautiful message

[little trail]

Sorry if this is "so obvious" but how would I sent it with broadcastMessage?

[young knoll]

broadcastMessage does not support components

[little trail]

so how on earth do so many servers use links

[sullen marlin]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Server.Spigot.html#broadcast(net.md_5.bungee.api.chat.BaseComponent...)

[hasty prawn]

The Spigot class

[little trail]

editor is telling me broadcast is 2 strings not components

my server object is an org.bukkit.Server

[sullen marlin]

.spigot().broadcast

[young knoll]

Huh, why did I assume that didn't exist

I guess because .spigot stuff is still kinda weird :p

[sullen marlin]

at the end of the day its just a loop

you can build it from sendMessage

[young knoll]

Has deprecating .spigot and merging it into bukkit ever been considered?

[sullen marlin]

its complicated, and also a bit pointless

because if you want to support any older version you'll just use the old method anyway

[slow oyster]

I forget there are spigot additions since I just depend on Bukkit

[sullen marlin]

which hasnt been supported for a long time now

[young knoll]

True

[sullen marlin]

we dont even publish bukkit to the maven repo since 1.15

[slow oyster]

Huh? As in depend on it in a plugin?

Oh

[young knoll]

.spigot() stuff comes from the days when spigot and bukkit had different maintainers :p

[slow oyster]

Maybe I am using spigot then

[young knoll]

I think this was also shortly after dinosaurs went extinct

[slow oyster]

Ah yeah <dependency> <groupId>org.spigotmc</groupId> <artifactId>spigot-api</artifactId> <version>1.14.4-R0.1-SNAPSHOT</version> <scope>provided</scope> </dependency>

youre not running spigot

[serene egret]

your missing your main method?

[young knoll]

Also

[serene egret]

smth like that

[young knoll]

patched_1.17.1.jar:git-Purpur

[quaint mantle]

bla bla bla

[half spoke]

I am running purpur 1.17

[young knoll]

This isn't purpur

Anyway

Your main class entry is wrong

[slow oyster]

Man as a plugin dev all the derivatives of Bukkit really cause a lot of headaches, so many times I've had to completely change an event because Paper disables it or something similar 😄

[serene egret]

for some reason i cant figure out a way to cound this array to display on the tab footer, is there a better way of doing this?

sorry for cutting in

[slow oyster]

A List isn't an array use .size()

[buoyant viper]

u can just call .size from getOnlinePlayers

[half spoke]

It's not? That is what I downloaded

[young knoll]

This

Is a discord for spigot

[buoyant viper]

we are spigotmc

not purpur

[half spoke]

yes well I was coding the plugin for spigot

[buoyant viper]

does the class exist?

[little trail]

You may want to update that as it says HoverEvent(Action, BaseComponent) is depreciated, and (Action, String) doesn't exist, what do I use then?

[buoyant viper]

is the package correct?

[half spoke]

the class exsists.

It should be correct

[buoyant viper]

it might deprecated for being new, like the hide/showPlayer stuff

[buoyant viper]

double check it idk

send plugin.yml

[little trail]

So if it's depreciated what am I meant to use?

[buoyant viper]

?paste

[undone axle]

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

[buoyant viper]

the components

[young knoll]

Read the javadocs

[little trail]

what

[young knoll]

They tell you why something is deprecated

[little trail]

i can’t though, it says "JavaScript is disabled" when it isn't

[buoyant viper]

its like how Player#showPlayer and hidePlayer are deprecated, but theyre new methods

[little trail]

On bungee ones, not the spigot ones

[buoyant viper]

so it could be something like that

[half spoke]

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

[little trail]

However I don't know

(It's not)

[buoyant viper]

now send ur main plugin class

[tender shard]

hidePlayer and showPlayer aren't deprecated when you use the correct one

[buoyant viper]

?paste

[undone axle]

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

[little trail]

I'm not using that though

[half spoke]

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

[little trail]

nop

[buoyant viper]

are the right ones not the currently deprecated ones?

[tender shard]

no -> https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#hidePlayer(org.bukkit.plugin.Plugin,org.bukkit.entity.Player)

[buoyant viper]

the package is wrong @half spoke

[young knoll]

package ro.fr33styler.grinch;
vs
ro.Fr33styler.GrinchSimulator.Main

[serene egret]

does this make sense?

[young knoll]

yes

[buoyant viper]

oh it takes a plugin argument now hmm

[little trail]

So what am I meant to use

if the constructor HoverEvent(HoverEvent.Action, BaseComponent[]) is depreciated and the bungee javadocs don't like any browser I use

[buoyant viper]

look around otherwise mayb some1 else knows ¯_(ツ)_/¯

[young knoll]

It's not deprecated

[young knoll]

Let me guess, you are using the Paper API

[tender shard]

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

[young knoll]

Ah wait right

It's content now

[little trail]

So the ?jd is the wrong link?

as the bungee one there doesn't include hover event at all

But the one you sent does

[tender shard]

no its the correct link

[buoyant viper]

exactly what it says

[tender shard]

and error stating java couldnt the class

[buoyant viper]

java couldnt the class

[tender shard]

let me guess. you only set the value once and never update it

[tender shard]

How exactly do I even construct Content when it's empty

[foggy estuary]

https://paste.md-5.net/midavuzayu.java anyone know why when the entity is dead the other mob doesnt spawn?

[little trail]

Like I don’t know, a string?

[foggy estuary]

or anything

[tender shard]

check the javadocs, Content is an abstract class

it has subclasses, e.g. Text

new Text("string") is a Content

[tender shard]

does your code even run to the point where you spawn a ravater?

[serene egret]

i put it in the same function that loops the different headers i have set, but i cant call it from the main class now

[tender shard]

what is Players? a class?

[quaint mantle]

Hey, I am quite a newbie to MC java development. When building an artifact it builds without faliure. However when I check the directory it is set to there is no jar. Any ideas?

[tender shard]

how do you build it? maven?gradle? ...?

[quaint mantle]

I think maven

[tender shard]

it's by default in the "target/" directory

[serene egret]

just an int

[slow oyster]

Players is going to be out of scope outside of the run() function so you can't access it?

[tender shard]

then you shouldn't call it it "Players" but players

[tender shard]

also this ^

[slow oyster]

create a static variable in your class probably

[tender shard]

ugh no not at all

[foggy estuary]

yes

[quaint mantle]

I set it to a folder on my desktop, yet didn't any jars built, Ill grab some screenshots.

[tender shard]

why would you want to store the amount of players the server had on startup instead of updating it every second or everytime a player joins leaves?

why don't you just directly use Bukkit.getOnlinePlayers().size()?

no need to cache that in some static variable that you will then have to update everytime

[tender shard]

so you set it up in your pom to save it to your desktop?

[slow oyster]

This, I assumed they needed it for something else

[tender shard]

yeah but still, doing "int players = ..." will never update automagically, which is what they are probably expecting^^

[quaint mantle]

oh sorry I meant gradle

[tender shard]

where did you set the output path? in your build.gradle file?

[quaint mantle]

Hmm it appears to be empty

[tender shard]

if your build.gradle is empty, you probably are not using gradle ^^

[foggy estuary]

if(evok.getHealth() <= 0) {

is this right though?

if it dies

[tender shard]

I doubt the damage will ever be 0 when you set it to 749 like one line above

[foggy estuary]

well do you know why once i kill it the ravanger doesnt spawn...?

[tender shard]

the if will always be false

[foggy estuary]

y

[tender shard]

because 749 is not <= 0

[foggy estuary]

how do i make the other mob spawn once the evok dies

[tender shard]

by stopping to set the evoks health to 749 before checking whether it's dead

[foggy estuary]

i dont understand, thats what i did. no?

[serene egret]

this wont work either

[tender shard]

you probably only run this code once and then ever again, correct?

[serene egret]

yea

[young knoll]

That won’t work

[tender shard]

as I said, it will never update then

[young knoll]

The number of players online changes

[serene egret]

should i loop it or rerun this function periodically

[young knoll]

Yes

Use a schedular

[tender shard]

it's like writing down your age on a piece of paper and then looking at it next year. the number won't have changed unless you write down your new age again

[young knoll]

Or placeholder API, it could handle this

[serene egret]

how can i declare this to be used in the footer

[tender shard]

that does not make any sense at all

have a look at this:

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[tender shard]

and about spigot scheduler programming

[serene egret]

alr

[tender shard]

e.g.

        Bukkit.getScheduler().runTaskTimer(yourPlugin, () -> {
            // Everything here runs one per second (every 20 ticks)
        }, 20L, 20L);

[young knoll]

?scheduling

[undone axle]

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

[tender shard]

everything inside of that will run once per second

[misty current]

hey, i wanna get into bungee development and i'd need to create multiple instances of the same server and it's pretty annoying that everytime i need to change something in the spigot servers i need to go ahead and copy paste it multiple times. Is there a better way to manage it?

[tender shard]

I just have symlinked all my .jars and their configs

[misty current]

what do you mean?

[tender shard]

all plugins and their configs aren't actually inside every server's plugins/ folder but inside another folder

and all server's only have "symbolic" links to the actual files

so all servers share the same plugin files

[misty current]

o

[young knoll]

Huh

[misty current]

how can you do that?

[young knoll]

Does that apply to the plugin data too

[tender shard]

on linux: ln -s [target] [linkname]

[tender shard]

depends on the plugin and what file. e.g. you can easily symlink WorldEdit's config but you shouldn't also symlink WorldGuards region storage^^

[young knoll]

Ahh

[tender shard]

e.g. ln -s ~/servers/lobby/plugins/WorldEdit.jar ~/plugins/WorldEdit.jar

[young knoll]

Shame,

[tender shard]

now WorldEdit is actually at ~/plugins/ instead of inside ~/servers/lobby/plugins

[young knoll]

Why can’t I just symlink the world itself :p

[tender shard]

and you only have to update one .jar file or config and all servers get the update

[misty current]

dam i need to learn to use bash

java not enough 😔

[tender shard]

e.g. if you have 5 servers:

for server in server1 server2 server3 server4 server5; do
  ln -s ~/servers/$server/plugins/WorldEdit.jar ~/plugins/WorldEdit.jar
done```

[round elbow]

sooo I am experiencing this weird ass thing
new Location(Bukkit.getWorld(a.split(" ")[3]), x, y, z).getBlock().setType(Material.HEAVY_WEIGHTED_PRESSURE_PLATE);
This sets a specific block to iron pressure plate
but it actually doesnt even if i fire this 1000 times
Unless i restart the server
is there a way to make it work by reloading the plugin instead of restarting the whole server? it seems to fire correctly without any errors but it doesnt physically work until server is restarted

[misty current]

i mean in general

recently i've found many cases where i need it

also rn i'm on windows since i'm testing in localhost

[young knoll]

I’d love to have a survival setup that is fully synced

But that would not be an easy task

[tender shard]

git bash 🙂

you can easily get git bash and learn shell on windows

I use it all the time to do stuff much faster than in explorer

[misty current]

so i can use bash command on windows?

[tender shard]

sure

[misty current]

o useful

[tender shard]

https://gitforwindows.org/

[misty current]

thanks

[tender shard]

np 🙂

but of cuurse you won't have ALL the typical linux commands

stuff like find, top, ps, grep is of course included, but you won't find stuff like systemctl

[misty current]

but i could do this

couldn't i

[tender shard]

sure, that only requires ln

that's included

[misty current]

what does the $ do in there?

$server

[tender shard]

it's a variable

e.g. look at this:

[misty current]

oh the bar

bar

var

ffs spelling

from the loop

[tender shard]

for name in mfnalex kill05; do
  echo $name
done

this prints

mfnalex
kill05```

[misty current]

it will send mfnalex and kill05

oh ye

[tender shard]

yes on 2 lines though

[misty current]

yup like println

i kinda know the basics because i used to make those shutdown files to mess with my friends

:p

[tender shard]

you can also easily do stuff like this

for file in logs/*.gz; do rm logs/$file.gz; done

so it also supports glob expanding (the * thing for files) and much more

[misty current]

so this runs something for every file

in logs

[tender shard]

that ends with .gz

yes

[misty current]

ahh oke

thanks

[tender shard]

np

[misty current]

and the tilde refers to the path the bash is in

doesn't it

[tender shard]

no

~ is your home path

e.g. /home/mfnalex or C:\Users\mfnalex

the current path is just a dot:
rm -rf . deletes the current directory and all it's contents

and .. is the folder above your current path

~ is just short for $HOME

[young knoll]

Wait I can figure this out

It deletes all .gz files in logs

[tender shard]

yep

Oh wow discord butchers that

[sullen marlin]

[wooden fable]

Thx md_5!!

[misty current]

oke lemme do some big brain coding

[tender shard]

ok 😄

but be aware, bash's if syntax is a bit weird

[unreal quartz]

""

[foggy estuary]

                if(e.getEntity().hasMetadata("Vin")){    
                    if(ent.isDead()) {``` ok well i did this too and nothing happend

[young knoll]

Debug it

[tender shard]

yeah, for spaces, have to be quoted

correct

[misty current]

what's the pause equivalent of bash

[young knoll]

Where does the code stop, add some print statements

[unreal quartz]

sleep

[young knoll]

Or attach an actual debugger if you want to be fancy

[tender shard]

pause for time or pause for a keypress?

[misty current]

keypress

[tender shard]

read

[unreal quartz]

-p switch

[tender shard]

read -p "Enter Text: " var puts the entered text into $var

just read simply waits for you to press enter

[misty current]

ok bash weird fr

[tender shard]

it's not weird 😄

it's just different 😛

[misty current]

you can't have spaces before and after the =

[tender shard]

nope, you can't

because it wouldn't make sense

[unreal quartz]

Because a bash script is literally a series of lines as you would write into your shell

[misty current]

ah right

makes sense

[tender shard]

echo = hi =
for example should print "= hi =" instead of assigning a variable

[unreal quartz]

var = a
it would take arg0 as 'var' and try to find a program calledl 'var' in your path

with = and a as arguments to the program 'var'

[quaint mantle]

Is it possible to give a falling block a name and check if it landed?

[tender shard]

https://www.learnshell.org/

[tender shard]

a visible name?

[quaint mantle]

yes

[misty current]

oke ima give it a look and stop annoying yall

thanks for the help

[tender shard]

not sure about that, just try it, they are regular entities

[quaint mantle]

okay

[tender shard]

you're not annoying, just open a thread if you have questions

[quaint mantle]

how do I check if he landed?

[quaint mantle]

if the entity is missing?

[tender shard]

Entity#isOnGround

or do you mean when it has turned into a solid block?

[misty current]

oke

[tender shard]

if so: Entity#isValid should work

[quaint mantle]

yes

[tender shard]

if it's no longer valid, it's either dead or has despawned for other reasons, so that should work

[quaint mantle]

When he fell

[tender shard]

yeah as long as it has turned into a solid block, it probably is not valid anymore

so FallingBlock#isValid will be false once it landed

[quaint mantle]

okay, thanks

Anyone have a idea about a good practice plugin with boxing?

[young knoll]

I have alot of named entities and its spamming the console when they die

[tender shard]

I don't think you can besides replacing the logger

[quaint mantle]

Yes but atm I need any plugin

Anything

[tender shard]

maybe you can also add a filter to the existing logger

If you aren’t coding it yourself

player.sendMessage(TextComponent); is deprecated.

Does someone know how i can convert a ChatComponent into a Component so i can send it non deprecated?

[tender shard]

there is no Player#sendMessage(ChatComponent) in spigot

[wooden fable]

Oh i meant TextComponent

[tender shard]

That doesn't exist too

it's all String

[young knoll]

Player.spigot().sendMessage

[tender shard]

yeah but they said they use Player so I thought they must be using paper api or sth ^^

Quick question does the PDC Persist between Item and Placed state?

[tender shard]

no

blocks do not have a PDC

[wooden fable]

TextComponent message = new TextComponent(".. .. ..");

[tender shard]

TextComponent.fromLegacyText("...");

[young knoll]

Did you see this?

[tender shard]

Text only extends Content which is no Component

[wooden fable]

message.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new Text(new ComponentBuilder("Klik hier om te joinen!").color(ChatColor.GOLD).create())));

I used it in my hover event

[tender shard]

if you need a PDC for blocks check out my tiny lib https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[tender shard]

and that's deprecated?

what is "message"?

ah a TextComponent I see

and on what are you calling sendMessage on?

[wooden fable]

Player p = (Player) sender;
            TextComponent message = new TextComponent("[FloppieSMP] Klik hier om de discord te joinen!");
            message.setColor(ChatColor.GOLD);
            message.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new Text(new ComponentBuilder("Klik hier om te joinen!").color(ChatColor.GOLD).create())));
            message.setClickEvent(new ClickEvent(ClickEvent.Action.OPEN_URL, "discord invite link lol"));
            p.sendMessage(message);

Full code

[young knoll]

Inb4 paper API

[tender shard]

p.spigot().sendMessage(message);

@wooden fable

[wooden fable]

still deprecated

[unkempt peak]

Ah nvm it turns out there is a config option in spigot.yml for named entity logging

[tender shard]

no it isn't

[candid quail]

@tender shard The blocks I'm using it on stem from TileState

[young knoll]

Then you can just use normal pdc

But it won’t automatically transfer when you place an item

[candid quail]

Just running into weird issues porting some nms code into PDC items

[tender shard]

if it has a PDC it will be consistent, but as said you have to set it yourself to the placed block

[young knoll]

Use the BlockPlaceEvent

[wooden fable]

p.spigot().sendMessage(message);

[candid quail]

@tender shard take a poke:

    @EventHandler
    public void onPlayerPlaceBlock(final BlockPlaceEvent e) {
        Player p = e.getPlayer();
        if (!(e.getBlock().getState() instanceof TileState))
            return;
        else {
            if (e.getItemInHand().getItemMeta().hasLore()) {
                NamespacedKey k = new NamespacedKey(LabToolsPlugin.getPlugin(LabToolsPlugin.class), "cid");
                PersistentDataContainer co = e.getItemInHand().getItemMeta().getPersistentDataContainer();
                CraftableBlock c = CustomBlocks.get(co.get(k, PersistentDataType.STRING));
                String uid = co.get(k, PersistentDataType.STRING);
                TileState state = (TileState) e.getBlock().getState();
                PersistentDataContainer con = state.getPersistentDataContainer();
                con.set(k, PersistentDataType.STRING, uid);
                state.update();
                c.Place.Run(p, state);
            }
        }
    }

[buoyant viper]

paper!

[young knoll]

Yep paper API

Called it

[wooden fable]

Wait does it matter or not?

[tender shard]

you are using paperAPI, they have everything marked as deprecated, go to paper discord's or stick with what spigot API tells you is deprecated and which isn't

[buoyant viper]

maam this is a spigot discord

[tender shard]

yes paper marks 50% of stuff as deprecated

[young knoll]

Paper deprecated all bungee component methods

[wooden fable]

Oh okay thx!!!

[tender shard]

of course they will still work, they just want to use their system instead

but since they want to be compatible with spigot, they will never actually remove spigot methods

[candid quail]

Pretty sure as I set my item on creation (through crafting, I set the cid (which previously worked in NMS)) on the object but then transfer the pdc state on block place to tilestate

[young knoll]

Hard fork™️

[tender shard]

I don't think getBLock().getState() will work because the block wasn't placed yet

you have to run it in a task instead

[candid quail]

Hmm, it's a pretty weird state tbh I've had it working with NMS

I'm switching out all my NBT Tag compounds to be PDC

@tender shard I'll give it a go

[tender shard]

tbh it's still easier to use my library

because you have block PDC's regardless of the block's state

so you can just instantly set a PDC value to the block, regardless of it was already placed or not

[candid quail]

I'll defo take a look!

[tender shard]

you can just do
PersistentDataContainer pdc = new CustomBlockData(yourBlock, yourPlugin);

then you have a PDC for that block 🙂

[young knoll]

I assume it uses chunk pdc

[tender shard]

ofc

[young knoll]

In the back end

[tender shard]

1.16.3+ only

it's just a wrapper around the chunk's pdc

[young knoll]

Nice

[tender shard]

yeah I had that idea in a dream

lol

[candid quail]

Ayy awesome

[young knoll]

World PDC when

[tender shard]

the default world has a PDC

[young knoll]

Does it

[tender shard]

erm well

kinda

it's not a real PDC, it's what PDC uses in NMS

[young knoll]

So NBT

[tender shard]

non mojang mapped:

WorldServer fromWorld = ((CraftWorld) Bukkit.getWorlds().get(0)).getHandle();
WorldPersistentData persistentData = fromWorld.getWorldPersistentData()
MinecraftKey key = new MinecraftKey("cuve")
NBTTagCompound storageNBT = new PersistentCommandStorage(persistentData).a(key)

yeah actually just NBT

well but you could also just abuse some spawn chunk's PDC for a world PDC 😄

[tender shard]

stolen from here: https://www.spigotmc.org/threads/persistent-data-container-custom-vanilla-storage.480780/

[young knoll]

True

I wonder if your block pdc would ever make it as a PR

[gentle oriole]

hi, is the if statement return immediately if the first operand is true? or does it check all the operands before it returns true?

[tender shard]

no idea, never did any D:

[tender shard]

depends on | or || or & or &&

[gentle oriole]

||

[tender shard]

|| = lazy, it stops once the first is not true

[young knoll]

It will short circuit

[tender shard]

| = continue to check all anyway

[young knoll]

So it will stop as soon as it finds a true

Or false in the case of &&

[tender shard]

I hate using | or & because it always looks like some bash commands

[gentle oriole]

well, ive been getting null errors recently

anddd the only problem i can se is in the if statement

[tender shard]

if(object == null || object.someMethod())

can NEVER throw an NPE

unless you run it async and have very bad luck

[gentle oriole]

npe?

[tender shard]

nullpointerexception

[young knoll]

args[x] will never be null in a command

Check the length

[tender shard]

can easily throw an NPE if modules is null or enableDisable is null

[gentle oriole]

how do I do it?

[young knoll]

args.length

[gentle oriole]

oh

[young knoll]

Granted that would not be an NPE, but still

[tender shard]

yeah it would be ArrayIndexOutOfBounds. Maybe show the actual error you got @gentle oriole

[gentle oriole]

null

[tender shard]

then either modules is null or enableDisable is null

[gentle oriole]

yes.

[misty current]

ok so i tested with it a bit (1 am shell o.o) with text files and i couldn't get it to work with symbolic links

[candid quail]

Ugh the NBT Tag Data is 10x more versatile than the PDC

[young knoll]

Not really

You can put anything in pdc with a type adapter

[hasty prawn]

So what actually implements PersistentDataHolder? TileStates, Entities, and Chunks?

[tender shard]

no. PDC can store ANYTHING

[tender shard]

and ItemMeta

[misty current]

when i edit a text file the other one doesn't change if i use -s as an arg

[young knoll]

In fact PDC is NBT

[hasty prawn]

Ahh gotcha

[young knoll]

It’s just a wrapper

[tender shard]

what exactly didn't work?

[misty current]

when i edited a text file the other one didn't change

[tender shard]

let me check

[misty current]

while -f worked just fine

[candid quail]

But the PDC is rubbish at actually being Persistent, I had NBT Tag Data that could Persist from a precrafted state where as the PDC is wiped upon creation of a new Item on Crafting

[unreal quartz]

Some things simply won't work with symlinks

e.g. vim cannot read symlinked .vimrc configuration files

[young knoll]

You can easily copy the data yourself

[tender shard]

oh yeah, seems like windows doesn't properly support symlinks then

let's see about hard links

[young knoll]

I don’t think NBT is automatically copied when crafting

[misty current]

hard worked

[young knoll]

It is in smithing tables though

[misty current]

at least with text files

[gentle oriole]

im still getting null error. ive already changed it to

(args[0].length() != 1 && args[1].length() != 1) || !modules.contains(args[1]) || (!enableDisable.equalsIgnoreCase("enable") && !enableDisable.equalsIgnoreCase("disable"))

[candid quail]

@young knoll it's crazy but it did

[tender shard]

just use ln without -s

windows doesn't support symbolic links properly

you can create hard links instead

[young knoll]

That’s more wrong

[misty current]

yeah sad

[tender shard]

ln file1 file2

[young knoll]

Drop the indexes, it’s just args.length

[tender shard]

works fine

[gentle oriole]

ah

[misty current]

i've added the -f so i don't have to delete the files if i need to rerun it for any reasons

[unreal quartz]

Your hostname is jagermeister

[misty current]

also does it persist through restarts?

[unreal quartz]

That's actually great lol

[candid quail]

Any ideas on Persisted Data from a Precrafted to a Crafted State (Without NBT)

[gentle oriole]

you mean just args[0].length()?

[young knoll]

No

[tender shard]

yes, my servers have organ names instead 😄 kidney, lungs, ...

[young knoll]

args.length

Like I said

[gentle oriole]

but

AAHHHH

[unreal quartz]

😳

[gentle oriole]

I UNDERSTAND

I've abstracted a lot of the item creation process, for example to create a new custom item all I have to do is use this CraftableItem item = new CraftableItem(Material, Name, Lore, UniqueObjID, Material{} Recipe, ExecutionCodeOnUse()) in that same regards previously the NBTTag Data could persist as a part of the metadata container as it was treated as the same, whereas the PDC is not maintained between a precrafted and a crafted state, any suggestions on circumventing this would be bril

[gentle oriole]

its still erroring null...

public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        String enableDisable = args[0];
        String module = args[1];

        if (args.length != 2 || !modules.contains(args[1]) || (!enableDisable.equalsIgnoreCase("enable") && !enableDisable.equalsIgnoreCase("disable"))) {
            System.out.println(1);
            sender.sendMessage("Usage: /" + command.getName() + " [enable|disable|list] " + modules);
            return false;
        }

[young knoll]

Use the craft item event to copy the PDC to the output

[tender shard]

show the full stacktrace

[karmic grove]

so i wanna make my plugin combatible with lands plugin it says to add ```java
private final LandsIntegration landsIntegration;

public IntegrationExample(Plugin yourPlugin) {

    // view methods of this class: https://github.com/Angeschossen/LandsAPI/blob/4.8.17/src/main/java/me/angeschossen/lands/api/integration/LandsIntegrator.java
    this.landsIntegration = new LandsIntegration(yourPlugin);
}

// just a test
void test(Location location) {

// get a land area from a location
final Area area = landsIntegration.getAreaByLoc(location);

// check is a location claimed
final boolean isClaimed = landsIntegration.isClaimed(location);

}

[candid quail]

Hmm I'll take a look

[young knoll]

It does not say to add that in plugin.yml

That’s java code

[tender shard]

that definitely does not belong to your plugin.yml

[young knoll]

You just need softdepend: [lands]

Or whatever the name is

[karmic grove]

thats all i need to add

[young knoll]

For the plugin.yml, yes

It will ensure lands loads before your plugin

[gentle oriole]

it says its happening here: String module = args[1];

[karmic grove]

oh ok

[tender shard]

that can't be unless args is null in which case the line above would have already thrown an error

show the full stracktrace pls

[gentle oriole]

whats the thing called

the site

you can paste

[tender shard]

?paste

[undone axle]

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

[gentle oriole]

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

[tender shard]

oh btw @misty current when installing git bash, there's an option enable support for real symbolic links

[misty current]

O

Thanks

[young knoll]

It does inside say array index out of bounds

[unreal quartz]

Alternatively, you could install Linux

[misty current]

I'll change tomorrow

[young knoll]

That should have been a reply, blah

[tender shard]

C:\ProgramData\Git\config

you can enable it in that file

[young knoll]

Discord let us add a reply when editing

Kthx

[tender shard]

that's no NPE, that's ArrayOutOfBounds because you only have 1 argument instead of 2

[gentle oriole]

i dont have any arguments?

[young knoll]

Yeah

[gentle oriole]

i only did /ad

[buoyant viper]

alternatively, u could install Linux

[tender shard]

you do, otherwise args[0] would throw the exception already

[young knoll]

It does?

[twin sapphire]

How can i send TextComponent with ClickEvent with the MessageRaw Channel? I dont get it

[young knoll]

It says index 0 out of bounds for length 0

[gentle oriole]

i dontttt????

[tender shard]

sure, /command returns an array of length 0

[young knoll]

Yes

So 0 arguments

[tender shard]

so what's "enableDisable" then?`...

[gentle oriole]

its either enable|disable

but i didnt put anything in there when executing the command

[tender shard]

so you have an argument

[tender shard]

ah yes I see, this time the error was thrown in the line where you do enableDisable = args[0]

because you access the first element of the array (args[0]) although there is no first element

[young knoll]

There is no spoon

[tender shard]

check the length of the array before accessing it's contents

[buoyant viper]

god imagine per-chunk difficulty

[young knoll]

I mean

[gentle oriole]

so I just put the if statement higher, and change all the variables to args

[young knoll]

The game does kinda have that

[buoyant viper]

its per world iirc

[young knoll]

Local difficulty exists

[tender shard]

yes

[young knoll]

Controls stuff like the chance for mobs to wear armor

[gentle oriole]

but why did it say it errored on line 19

not 18

[tender shard]

the longer you stay inside one area the harder it gets there

[young knoll]

^

[tender shard]

what is line 19?

[young knoll]

You can see it in F3

[gentle oriole]

String module = args[1];

line 18 is String enableDisable = args[0];

[young knoll]

Both of those won’t work if you have no args

[tender shard]

then your .jar doesn'T match your source code

you changed your code without recompiling and restarting the server if line 19 is the one with args[1]

your stacktrace cleary says that line 19 is the one with args[0]

[gentle oriole]

ah maybe it happened when I formatted it

[tender shard]

yeah probably^^

check the args.length() before accessing anything from it

[young knoll]

just length

It’s not a method

[tender shard]

oh right

[gentle oriole]

ah it finally worked

[tender shard]

if(args.length < 2)
// tell player "you need at least 2 arguments" and return
// now you can access your stuff
String val1 = args[0];
String val2 = args[1];

[gentle oriole]

so String val1 = null; null error?

[young knoll]

No that’s valid

[tender shard]

no

[gentle oriole]

eh?

[young knoll]

You just can’t do something like val1.trim() if the string is null

[tender shard]

String val1 = null; // fine
val1.toLowerCase(); // NullPointerException. "null" doesn't have a toLowerCase() method

[tender shard]

^

[gentle oriole]

but didnt the error happened on String val1 = args[0];

and args[0] is null

[young knoll]

Yes but It wasn’t null

[tender shard]

yes, but you didnt have any nullpointerexception...

[gentle oriole]

it wasnt?

[young knoll]

It was array index out of bounds

Because index 0 did not exist

[tender shard]

As I already said 3 times, you had an ArrayIndexOutOfBoundsException

[gentle oriole]

ooohhh

[young knoll]

Any variable can be null just fine (except primitives), you just can’t invoke any methods on said variable

[tender shard]

the "null" at the top is just the missing exception message

[gentle oriole]

oh, I understand now.

thanks a lot

[tender shard]

np^^ next time pls instantly send the full stacktrace 😛

[tender shard]

DId you define a ServerManagerPlugin class inside both of your .jars or maybe even shaded the one into your other?

because if so of course they have the same name but they don't extend each other or sth

[worldly vessel]

Nope. I checked the jar.

Its even on the same java version

[stone apex]

Players that first join have a death bug.. I have 3 plugins. My first plugin teleports them to the new world at 0, 68, 0. The second plugin has an EventHandler that picks up on the change of worlds and teleports that player to the center of their plot. The third plugin is the plot plugin. I don't know why people are dying when they get sent to that world for the first time, once it happens once it never happens again..

But this is java code

[hushed badger]

hmm

maybe difference in height during tp?

what's the death msg?

[stone apex]

It's just player died in console

They are teleporting from y = 64 to y = 68

[candid quail]

@young knoll you free to jump in General to help me out with the CraftItemEvent?

[hushed badger]

maybe listen to the PlayerDeathEvent and see why it says they're dying...? maybe cancel if during the first few ticks of the player's existence...? idk

[stone apex]

That is a patch for sure

[hushed badger]

what MC ver?

[stone apex]

1.18.1

[hushed badger]

mmk

[stone apex]

Using paper-109 but it's been around a bit

[rough basin]

?paste

[undone axle]

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

[candid quail]

Anybody got an idea of comparing a CraftItemEvent to a ItemStack?

[rough basin]

i hate my code and life lmfao

[hushed badger]

seems odd. I'd try that first thing I said to maybe try and debug why they're dying

[next fossil]

How do you convert from a DataWatcher to SynchedEntityData?

SynchedEntityData sed = npc.getEntityData();

It keeps giving me errors saying its a DataWatcher object, but there is none for the new Mojang Mapping itself

I keep getting NullPointerExceptions too because of it

[gentle oriole]

ArrayList<String> disabled = Modules.disabled; if I modify disabled, will Modules.disabled get modified as well?`

[young knoll]

What? You can’t compare an event to an item

[unreal quartz]

What is disable

[gentle oriole]

*disabled

[unreal quartz]

Yes

[gentle oriole]

typo

[candid quail]

@young knoll more so extracting the result of the event in order to track down which custom it is to apply the pdc data I need to it

Happy to jump in general and show you where I'm stuck lol

[gentle oriole]

Hello, I have a problem. So firstly, I have two ArrayList String in class Modules. One of them is modules and the other one is disabled. Secondly. I have imported both said ArrayList into my Commands class.

    ArrayList<String> modules = Modules.modules;
    ArrayList<String> disabled = Modules.disabled;

Thirdly, I have a command that if I type /ad disable all, disabled = new ArrayList<>(modules); will execute. Causing Modules.modules to my knowledge to update. Fourthly, I have !disabled.contains("playerSlipped") in another class imported again using ArrayList<String> disabled = Modules.disabled;, The problem is !disabled.contains("playerSlipped") still returns true after executing /ad disable all. Fifthly, It only returns false when I reload confirm the server after executing /ad disable all

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/CraftItemEvent.html#getInventory()

The inventory should have a getResult

[unreal quartz]

Your third assumption reassigns what the local variable “disabled” points to

[rough basin]

It seems that the task never works or is created, but no error is generated,
and the code in the previous line works normally. Is there any way to solve this problem?

Here is a full code of event and Task.
https://paste.md-5.net/pifirayosa.java

[gentle oriole]

yes, I want to copy the values of modules into disabled

[unreal quartz]

See array list clone method

[gentle oriole]

Clone() doesnt work

[unreal quartz]

Well it does

[gentle oriole]

im confuused

[ebon siren]

cast it

[candid quail]

@young knoll no joy

[stone apex]

I would need a test user to join for it to work. The bug is possibly because the player doesn't own the plot for that tick, or a schematic being pasted at coordinates can kill someone idk. Maybe I should just have a delay between teleports

[candid quail]

Wait

Figured it out

[ebon siren]

Object thing = new ArrayList<String>;
doTheFunctionThing((ArrayList<String>) thing);

or a more readable way

int someInt = 1;
float castedToAFloat = (float) someInt;

[gentle oriole]

ArrayList<String> disabled = Modules.disabled;
disabled = (ArrayList<String>) new ArrayList<>().clone();

System.out.println(disabled);
System.out.println(Modules.disabled);```Why doesnt it sync?

[young knoll]

Because .clone

[gentle oriole]

yes but isnt it supposed to sync with Modules?

when I reloaded it, thats when it synced. but disabled isnt syncing

[storm quarry]

how do you report a spigot plugin for using your code but making no mention/credit anywhere?

and i'm talking 90% of the codebase is my code not a little bit

[candid quail]

Ughh pdc

[young knoll]

Use the report button

[storm quarry]

the only report button I see is titled "Report Resource Update" which seems specific to an update or is that also just a general report button

[candid quail]

@young knoll am I not setting an Items PDC Correctly?

    @EventHandler
    public void onPlayerCraftItem(final CraftItemEvent e){
        List<CraftableItem> val = new ArrayList<CraftableItem>(CustomItems.values());
        List<CraftableBlock> CustomBl = new ArrayList<CraftableBlock>(CustomBlocks.values());
        Bukkit.getConsoleSender().sendMessage("Craft Event");
        for(int i = 0; i < CustomItems.size(); i++) {
            if(e.getInventory().getResult().equals(val.get(i).Item)) {
                NamespacedKey k = new NamespacedKey(LabToolsPlugin.getPlugin(LabToolsPlugin.class), "cid");
                e.getInventory().getResult().getItemMeta().getPersistentDataContainer().set(k, PersistentDataType.STRING, val.get(i).UniqueName);
                e.getWhoClicked().sendMessage(val.get(i).UniqueName);
            }
        }
        for(int i = 0; i < CustomBlocks.size(); i++) {
            if(e.getInventory().getResult().equals(CustomBl.get(i).Item)) {
                NamespacedKey k = new NamespacedKey(LabToolsPlugin.getPlugin(LabToolsPlugin.class), "cid");
                e.getInventory().getResult().getItemMeta().getPersistentDataContainer().set(k, PersistentDataType.STRING, 
CustomBl.get(i).UniqueName);
                e.getWhoClicked().sendMessage(CustomBl.get(i).UniqueName);
            }
        }
        

    }
}

[young knoll]

Should be general if you do it from the main resource page

[young knoll]

getItemMeta is a copy

You need to use setItemMeta after modifying it

[stone apex]

Can anyone join this server to see if they die lol not advertising but this death bug is the death of me

[candid quail]

Bout to fix a tonne of code @young knoll

[buoyant viper]

y cant u join n test?

[rough basin]

can someone help me

I just wants this task to repeat every 30 ticks and cancel itself.

[stone apex]

It was only happening when a player purchases a plot for the first time

I already have mine and don't wanna start up a giant test server it's a super weird bug

[buoyant viper]

ezpz just keep deleting ur profile data

f

[patent wadi]

Hi, I'm trying to spawn a entity with type player but it wont, can someone suggest a method for this please?

[young knoll]

You cannot

You need packets

[patent wadi]

hmm

[ancient plank]

I love reading code without syntax highlighting

[candid quail]

@ancient plank ayyy

If it ain't precompiled jars being opened in notepad it aint worth it

[young knoll]

Microsoft word

[candid quail]

Never switching between NBT and PDC ever again lol

[young knoll]

Just never use NBT again

[candid quail]

Pretty much

It's a personal project more than anything

But better to use best practices instead of trying to take the easy way out

Ayy my wireless redstone is working again

This time not just in 1.17

[swift adder]

how to get spigot?

[candid quail]

@swift adder Build tools

[swift adder]

oh okay

[mental moon]

Is there a masterlist of all the NameSpacedKeys for all the registered recipes?
I want to make something that will "discover" all recipes for a player on join but I can't find the list to iterate from, or how to populate my own list.

[swift adder]

i understand, thanks

[karmic grove]

is there a right click mob event or somthing like that or detect when damage is applied to certain mobs

[late sonnet]

Currently i think not... Only the defaults recipes

[sullen marlin]

There's Iterator<Recipe> in the Server class

[mental moon]

I was looking at that.
It returned a Recipe object.
Would I have to populate a list of ItemStacks, then iterate off of that?

[hasty prawn]

Bukkit.getServer().recipeIterator()

[swift adder]

http://jd.bukkit.org/rb/doxygen/dd/dcb/classorg_1_1bukkit_1_1event_1_1player_1_1PlayerInteractEntityEvent.html

[late sonnet]

In docs not say only return vanilla recipes? Or i missing the method

[sullen marlin]

Should return all recipes

[young knoll]

Assuming they have already been added

[mental moon]

Thanks, I'll look into it some more

[karmic grove]

thats not a real link

atleast dont work for me

[swift adder]

use the PlayerInteractEntityEvent

[hasty prawn]

And EntityDamageEvent when they're damaged ^

[swift adder]

get the player then get the entity type

[young knoll]

ong

glad they made such a website

[young knoll]

No idea what that other link was

bukkit.org, so probably very old

[mental moon]

I looked into the Recipe iterator, however I can't figure out how to turn that Recipe object into a NSK I can use for the #discoverRecipe(NameSpacedKey) function

[sullen marlin]

Check if Keyed, cast

Iirc there's still at least one type of recipe that isn't Keyed

[late sonnet]

In what case a recipe are not keyed (?

[mental moon]

Oh, I didn't realize recipes were a NSK. Thanks!

[late sonnet]

Or well maybe tomorrow can see what typw of recipe its not keyed xd

[sullen marlin]

Probably furnace recipe or something

One of the non crafting ones

[young knoll]

Merchant

Furnace is keyed

[late sonnet]

Merchant is a recipe?

[young knoll]

MerchantRecipe, yes

It technically extends recipe

[late sonnet]

I edit this class and dont remember xd

[young knoll]

implements*

[mental moon]

I'm probably not understanding right.
(recipe instanceof NameSpacedKey) gives me an inconvertible type error.
the only function off of recipe is #getResult() -> ItemStack

[young knoll]

Keyed

[mental moon]

Thank you, I found the NSK!

[rough basin]

Can someone Help me?

[sullen marlin]

What messages slow

Show

[rough basin]

Nothing

no Warning, no Errors.

just not working

[sullen marlin]

Did you register the event

[rough basin]

yeah i did

According to the debug message, it can be seen that up to line 16 is working normally.
But putting debug messages inside run() doesn't work either.

[fleet imp]

When I compile a Maven project, does it import the dependencies automatically?

or do i need the .jars in the same folder or some

[sullen marlin]

It does it automatically

[fleet imp]

then idk y im getting the err im getting. NoClassDefFoundError

[young knoll]

Did you shade

[static ingot]

If it's not a library used by Spigot, you have to shade it.

[fleet imp]

wat

idk what that means
