BlockDamageEvent

BlockDamageAbortEvent for if they cancel

[worldly ingot]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockDamageEvent.html, not the break event

[drowsy helm]

oops

yeah that one

[fierce dock]

Thanks! : D

[ornate patio]

well

it turns out you can only have names up to 16 characters

which is a huge bummer

that wont work for me

[lost matrix]

You still on this? Just use a mounted entity already...

[ornate patio]

I already have

The mounted armor stand is too low

where the name tag is inside the head of the player

[lost matrix]

Thats what happens if you make it a marker

[ornate patio]

but if it's not a marker it will interfere with hitboxes

[lost matrix]

Let it be a small as and set collidable to false

[ornate patio]

will that completely stop any interferences?

[lost matrix]

Yes. No collision and no arrows.

But this will only work if you are on a newer version

[desert frigate]

Stupid question but how do I use nms?

[lethal coral]

why is that a stupid question

[desert frigate]

idk

cause this is like my first week of java lol

[lost matrix]

https://www.spigotmc.org/threads/spigot-bungeecord-1-19.559742/

Scroll down to the nms section and setup the special sources maven plugin in your project.

[lost matrix]

Then do not tinker with nms.
Nothing there is meant to be used. Nothing is documented and you wont get any help.
Its all just reverse engineering and suffering.

[desert frigate]

i was just tryna make a npc and every video i watch told me to use nms

[desert frigate]

i already tried the dependency config but intellj keeps putting out a error on it

[lethal coral]

buildtools

[lost matrix]

^

[desert frigate]

java -jar BuildTools.jar --rev 1.18?

okay yeah i did everything from https://www.spigotmc.org/wiki/buildtools/

[ornate patio]

1.18.2?

[lost matrix]

should work

[desert frigate]

what did i do

[ornate patio]

Ok great

And the custom name won’t show for the player it’s mounted on right

[lost matrix]

You would need to do packet filtering for that

[ornate patio]

damnit

with ClientBoundDestroyEntities or whatever it’s called?

[lost matrix]

No. You just cancel the spawn packet for the as

[potent atlas]

Hello, is this the right place to get help coding a plugin?

[ornate patio]

How?

[ornate patio]

Yes

[potent atlas]

It's about the PlayerCommandSendEvent. I am trying to get the list of commands that gets sent to the user with e.getCommands() and it's telling me that it has a missing type "Collection" even though I've done all my imports

Does anyone have any ideas? I've been googling all day lol

[glad prawn]

https://pastebin.com/nH56EuZR

Why i can still dragging item when i already cancelled event.

[lost matrix]

If you properly cancel the InventoryClickEvent then you wont be able to drag items anymore.

[glad prawn]

I can still get all the items on the inventory.

[lost matrix]

Then you dont properly cancel the event

[glad prawn]

I honestly don't know where I went wrong…

[lost matrix]

Did you register the listener?

[wet vault]

Guys I am currently learning plugin development and I have made a really basic plugin so can anyone help me test it out?

[lost matrix]

Start an offline mode server and connect with two clients

[wet vault]

Yeah the thing is My laptop cannot handle that

[ornate patio]

Wait that’s a thing?

How does one do that

I’ve always had two Minecraft accounts

for reasons other than plugin development

[wet vault]

You host the server from your PC or Laptop

[ornate patio]

yeah of course

[wet vault]

You do not need two accounts

[ornate patio]

but it contacts mojangs auth servers though

[river oracle]

yes you do

[wet vault]

After that join from minecraft the server which you hosted

[wet vault]

You can access server.properties file in the server folder

[river oracle]

wait what how would you even do this I thought you needed an account to even launch the game

[wet vault]

DM me if anyone wants to help

[ornate patio]

oh so that’s where it is

[glad prawn]

Yes.

[lost matrix]

Add debug messages and debug your code

[wet vault]

Yes after accessing the server.properties file you can find online mode which will be true by default and then set it to false

[ornate patio]

How does one cancel a spawn packet to a specific player

[lost matrix]

Check who the receiving player is and cancel it regardingly

[lethal coral]

Ok so I'm trying to create a project with multiple modules in order to support different nms versions. What I'm wondering is if it'll still remap correctly with SpecialSource

[potent atlas]

Would it be helpful if I post the whole listener class for the PlayerCommandSend event that's not working?

[lost matrix]

If you set up the special sources plugin for each module then yes

[lethal coral]

I'm gonna get lost so quick 😭

I haven't done a module project before

[lost matrix]

Properly setup your jdk in your project. Collection is from java itself.

[potent atlas]

No idea what that means

[ornate patio]

How do I "check" who it is

[potent atlas]

I'll do some more googling. Thanks

[ornate patio]

Is there an event for when packets are sent?

[lost matrix]

Protocollib has that

[ornate patio]

Like when I call the World#spawn method

How would I just stop the packet for one player

[ornate patio]

Ah damn okay

Ive never used that before

[lethal coral]

do you know of a good spigot module plugin that I can use as an example

[lost matrix]

Hm not really

[lethal coral]

https://github.com/mbax/AbstractionExamplePlugin
this is all I have rn and it's from 8 years ago

😩

[chrome beacon]

https://github.com/SirBlobman/CombatLogX

https://github.com/SirBlobman/SirBlobmanAPI

[potent atlas]

I fixed the error but it still doesn't work. Gonna do some debug statements... and then idk lol

[chrome beacon]

If you can't figure it out you can always send the code

?paste

[undone axle]

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

[potent atlas]

Alright I confirmed that it's triggering the event and running the code, but it's not doing what I want 😛

[near kite]

@vestal moat

Ask here

[vestal moat]

No

I don't get support from spigot

Stfu

[potent atlas]

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

I'm trying to remove commands from the list that the players see

subcommands

that get run from clickable text

problem is I've heard of 3 different events to listen to. this one made the most sense

(the commands are still showing) EDIT: nvm! works now!

[ornate patio]

Does anyone know how to cancel an entity spawn packet with nms? Or maybe even ProtocolLib?

I want to spawn an entity in the world, but have it not exist for one player

[lethal coral]

how does it not have access?

[visual tide]

restart your ide

[potent atlas]

Thank you @lost matrix

[ornate patio]

bump

[hybrid spoke]

so either try to listen to it via protolib or destroy the entity immediately afterwards for the player

[ornate patio]

destroying the entity immediately sounds inefficient

how would you listen to it with protocollib?

[hasty obsidian]

    public static void onDrop(PlayerDropItemEvent e){
        if (e.getPlayer().getInventory().getItemInMainHand() != null){
            if (e.getPlayer().getInventory().getItemInMainHand().getItemMeta().equals(ItemManager.crown)){
                e.setCancelled(true);
            }
        }
    }``` anyone know why this not working?

[lethal coral]

ok so I'm making a multi module project and I'm trying to compile the whole thing into one jar file
the problem I'm running into right now is that each jar file is being completed individually

[hybrid spoke]

how so

thats probably how you do it

[ornate patio]

i mean

i feel like it should be possible to just send the spawn packet to specific players

[hybrid spoke]

listen to the sent entity spawn packet and cancel it

[ornate patio]

rather than sending spawn packets to every player and then another delete packet to one player

[ornate patio]

but how i kinda have no experience with protocol lib lmao

[hybrid spoke]

THAT sounds inefficient

just destroy it for the player who shouldnt see it

[ornate patio]

what does, first or second sentence?

[hybrid spoke]

https://github.com/dmulloy2/ProtocolLib/wiki
https://wiki.vg/Protocol

[ornate patio]

I need every player except one to see an entity

[ornate patio]

I'll do some experimenting

[hybrid spoke]

to intercept the spawn packet and then resend the spawn packet for only specific players

[ornate patio]

thats not what i meant

[hasty obsidian]

?

[ornate patio]

i just mean, "send the packet to all players but one", rather than "send the packet to all players and then send another delete packet to one"

[lethal coral]

bump

I'm not so good at xml so 😂

[hybrid spoke]

you need an uber module

which holds the ones you want to build as dependencies

f.e. https://github.com/olijeffers0n/PatheticAPI/blob/master/pathetic-mapping/pom.xml

[hasty obsidian]

    public static void onDrop(PlayerDropItemEvent e){
        if (e.getPlayer().getInventory().getItemInMainHand() != null){
            if (e.getPlayer().getInventory().getItemInMainHand().getItemMeta().equals(ItemManager.crown)){
                e.setCancelled(true);
            }
        }
    }```
anyone know why my code isnt working?

it doesnt give an error

it just doesnt work

[lost matrix]

Dont check metas for equality. Use the persistent data container of the meta to tag an item as a custom one.

[hasty obsidian]

ok

[lost matrix]

?pdc

[undone axle]

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

[lethal coral]

ok that's what I have but then when I do mvn package this is what it says, then proceeds to still build every single one

also a problem I have is that I'm using a maven plugin to remap and obfuscate the mojang mappings, and that's compiling into its own jar file just like the others

actually

nevermind!

it just outputs weird to this file name

[ornate patio]

I'm running into some strange desync issue

so I'm constantly teleporting an invisible armor stand on top of a player (mounting still didn't work- the name tag was either too high or too low)

and it works fine when both accounts are on the server when the plugin is reloaded

but when this "Jacob" accounts logs off and back on, this happens on my main account:

even though on the Jacob account, it still looks normal:

I have no idea what could be causing this. here's the code that's run when a player joins the server

private void updateArmorStand(Player player, String name) {
    ArmorStand armorStand = playerArmorStands.get(player.getUniqueId());
    if (armorStand == null || !armorStand.isValid()) {
        armorStand = player.getWorld().spawn(player.getLocation().add(0, ARMOR_STAND_Y_OFFSET, 0), ArmorStand.class);
        armorStand.setCustomNameVisible(true);
        armorStand.setGravity(false);
        armorStand.setVisible(false);
        armorStand.setInvulnerable(true);
        armorStand.setMarker(true);

        playerArmorStands.put(player.getUniqueId(), armorStand);
    }

    armorStand.setCustomName(name);
}

[small current]

the durability also gets checked

[chrome beacon]

Are you removing the armor stand when the player is logging out

[ornate patio]

yes

the armor stand is deleted when the jacob accounts logs off

[ornate patio]

private void removeArmorStand(Player player) {
    ArmorStand armorStand = playerArmorStands.get(player.getUniqueId());
    if (armorStand != null) {
        armorStand.remove();
        playerArmorStands.remove(player.getUniqueId());
    }
}

this is the code that's run on player quit or on player death

[chrome beacon]

That's not removing it from the world though

nvm

I'm blind

Have you tried delaying the armor stand spawn by a tick

[ornate patio]

yes

by 0, 1, and 10 ticks

[hybrid spoke]

i've had the same problem but didn't looked further into it. what if you "reload" the entity for the player?

[quaint berry]

Can I check for if a chunk has been generated?

[hybrid spoke]

also when doing custom titles you want to use packets for the armorstands

[ornate patio]

that's a thing?

[ornate patio]

yes

havent gotten to there yet

I'm gonna use packets to hide the armor stand from the player

[hybrid spoke]

in newer version you could hide/show the armorstand for all players, otherwise packets

[crisp steeple]

tfw hypixel just decides to completely disable playerinteractevent

[ornate patio]

I want the title to be visible to everyone except for the player it's on top of

[hybrid spoke]

a fake entity is the key here

[ornate patio]

i dont see any reload method for player or armorstand

[hybrid spoke]

^

[ornate patio]

fake entity on which client?

[hybrid spoke]

fake entity = sent by packets

no real entity

its not there other for the client

[ornate patio]

so you're saying instead I should just send fake armor stands to every player

[hybrid spoke]

yes

[ornate patio]

how do I teleport those armor stands on top of their respective players

[hybrid spoke]

you can keep track of them

otherwise mount packet

[ornate patio]

i have no experience with fake entities

how do i even start

[hybrid spoke]

well, first you need the entity

second you need to handle it (mount it, keep track of it, what happens if a player "unloads"(the entity will be gone as well, so resend the packet))

third what happens when you try to hit a player with a fake entity on him (you need to redirect the hit)

[ornate patio]

i mean

marker armor stands don't have hitboxes

so i dont think that'll be an issue

[ornate patio]

How do i do all of this lmao

I'm so lost

[quaint berry]

.

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#isChunkGenerated(int,int)

[quaint berry]

Thank yoooouuuu

Uhhh?

[chrome beacon]

Don't getChunk

That will load it

[quaint berry]

Oh

What would I use?

[chrome beacon]

To see if it's loaded?

[quaint berry]

If it's ever been generated

[chrome beacon]

.

[quaint berry]

I had a look but I don't understand

Ohhhh

I'm an idiot

[ornate patio]

Won’t this actually take up more memory though?

Because each player has their own set of fake armor stands (which are on top of other players)

[lethal coral]

how come whenever I do an entity spawn packet the entity isn't looking in the right location and the velocity vector does nothing pretty much

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/LivingEntity.html#setCollidable(boolean)

[eternal oxide]

pitch and yaw of Location are where the player will be facing

[ornate patio]

What does this have to do with my problem though

[eternal oxide]

my guess is your client thinks you are colliding with the stand so it pushes it

[hybrid spoke]

no, since all you are holding is a set (if even a set) of IDs per player. if you are really unnecessarily concerned about memory, use a profiler and sum the bytes

[lethal coral]

what are you talking about

[ornate patio]

How does that mess with visibility tho

[eternal oxide]

I thought your issue was teh stand gets moved up for teh spawnign player?

[lethal coral]

the xrot and yrot arguments in the packet constructor are regarding the entity's spawn location that you're spawning in

[eternal oxide]

are you talking about teh players facing or his head direction?

[lethal coral]

dude what

[eternal oxide]

^

There is a seperate packet for setting teh lookat

[lethal coral]

the entity being spawned via that packet is not looking in the correct direction and the velocity vector does nothing

[ornate patio]

One armor stand per player?

[lethal coral]

then tell me why it's an argument in the packet constructor

[ornate patio]

No

The issue is that the stand becomes visible and the custom names becomes invisible for some clients

[eternal oxide]

ClientboundRotateHeadPacket

[eternal oxide]

strange

[eternal oxide]

which packet?

[lethal coral]

the one I mentioned earlier

packetplayoutentityspawn

aka clientboundaddentitypacket

[eternal oxide]

there is a ClientboundAddEntityPacket which just takes a LivingEntity, unless you are trying to custom set its facing

[lethal coral]

it does not just take a livingentity

you can create a client entity via that packet

this is one of the higher level constructors

[ornate patio]

So here’s what I would do:
Have a hashmap with player UUIDs as the key and fake armor stands as the value (I have no idea how to create a “fake armor stand” instance)

Then when a player moves, I’ll send a packet to every other player to teleport the fake armor stand on top of the player that moves (no idea how to teleport fake entities either)

Does this look right?

[eternal oxide]

There is a contructor which takes a LivingEntity java LivingEntity livingEntity = null; new ClientboundAddEntityPacket(livingEntity);

[lethal coral]

sir

[eternal oxide]

I'm looking at it now

LivingEntity var0

[lethal coral]

if you looked at the code, you would see that it's Entity, which is a super class of livingentity

and there are multiple other lower level constructors that allow you to do more

[eternal oxide]

Yes, which is why I specifically asked you if you were just trying to spawn with a facing or you were trying to customize it

[lethal coral]

you never asked me that but ok

my question still hasn't been answered

why are both of the values in that packet if they don't do anything

[lethal coral]

there is more to the packet

😂

[eternal oxide]

ok be rude, ask someone else.

[lethal coral]

how am I being rude you're literally going on about one of the higher level constructors

when I have said I'm not using that one multiple times

[eternal oxide]

and I asked you why not, twice

[lethal coral]

public ClientboundAddEntityPacket(int var0, UUID var1, double var2, double var4, double var6, float var8, float var9, EntityType<?> var10, int var11, Vec3 var12)
this is the one I'm referriing to

[eternal oxide]

yes I know which constructor you are using, I'm asking why

[lethal coral]

because I'm allowing for options

full control of the packet

[chrome beacon]

So what's the problem? What actually do you need help with

[lethal coral]

let's start over

so

I have everything filled in and the zombie spawns

however

a) his velocity is static and doesn't seem to change (what is the last value for if that doesn't edit velocity)
b) var8 and var9 (xRot and yRot) seemingly have no impact as well

[obsidian drift]

Does anyone know how to create NMS entities in 1.19.1?

[chrome beacon]

Yeah

What part do you need help with

[obsidian drift]

The creation of the entity

[chrome beacon]

Use Level#addFreshEntity to spawn the entity in the world

[obsidian drift]

I mean like starting off from here

class Test extends EntitySkeleton {
                
}

[lethal coral]

look at the entityskeleton class

[obsidian drift]

Why does it have to take multiple EntityTypes?

public EntitySkeleton(EntityTypes<? extends EntitySkeleton> entitytypes, World world) {

[lethal coral]

it doesn't

[chrome beacon]

It takes the Skeleton Entity type

[obsidian drift]

'x()' in 'net.minecraft.world.entity.EntityInsentient' clashes with 'x()' in 'net.minecraft.world.entity.EntityLiving'; attempting to use incompatible return type

[chrome beacon]

Use Mojmaps

[eternal oxide]

The last value (d3) is the entities yHeadRot

[chrome beacon]

Unmapped is just a pain to work with and you run in to issues like that

[lethal coral]

I don't see a d3

[obsidian drift]

What's that?

[lethal coral]

mojang mappings

[chrome beacon]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

Replace 1.18.2 with the version you're using

[eternal oxide]

PacketPlayOutSpawnEntity(int i, UUID uuid, double d0, double d1, double d2, float f, float f1, EntityTypes<?> entitytypes, int j, Vec3D vec3d, double d3)

[obsidian drift]

Thank you

[lethal coral]

what version are you on

[eternal oxide]

1.19.1

[lethal coral]

I'm on 1.18.2, I do not have that value

[eternal oxide]

ah

[lethal coral]

I mean this is just an example I'm doing to make sure everything works. I just want to make sure there's nothing wrong on my end with my code for why the xrot, yrot, and vector have seemingly no impact

so I can better understand what's going on

[chrome beacon]

ElgarLs constructor is the same as your one

[lethal coral]

no

[chrome beacon]

It's just unmapped vs mojmaps

?

[lethal coral]

I do not have the last value

[chrome beacon]

ah'

[lethal coral]

I think I know the problem

and @eternal oxide tried to point it out earlier

just not perfectly since he didn't know my full context which is fine

I'm using the packet for minecarts and other nonliving entities (as stated by wiki.vg)

so those things probably don't have a major effect or not the one I expected

I'll give the other packet a go

[eternal oxide]

Thanks. Sorry I'm in and out as cooking wifes breakfast

[obsidian drift]

Any idea how I get the Level instance?

[buoyant viper]

Level nmsLevel = ((CraftWorld) bukkitWorld).getHandle(); probably

[chrome beacon]

Yeah

It's that

[obsidian drift]

Ty

[buoyant viper]

might be ServerLevel idk

[obsidian drift]

Yeah but it still works

ServerLevel extends Level

[buoyant viper]

oh i just genuinely didnt remember the mappings

[obsidian drift]

java.lang.NoClassDefFoundError: net/minecraft/world/level/Level

[chrome beacon]

How did you make your jar?

Make sure you used maven to build it

[obsidian drift]

Ah ok

[chrome beacon]

Maven tab on the right side > package
If you're using Intellij

[obsidian drift]

Yeah that works thanks

[lethal coral]

is there a way to get an entity object in spigot without spawning it

[chrome beacon]

NMS entity?

If so yeah just create an instance

They don't spawn automatically

[lethal coral]

no

😔

in regular spigot

[chrome beacon]

Then no

Not that I'm aware of

[lethal coral]

https://www.spigotmc.org/threads/creating-entity-without-spawning-it.314683/
was reading this thread and was hoping it was a thing by now

[chrome beacon]

You're already using NMS for packets

[lethal coral]

yes I am

me/the people using my plugin will not

[chrome beacon]

?

[lethal coral]

why the question mark

[chrome beacon]

wdym

the people using my plugin will not

[lethal coral]

I'm making something for future me to use without nms

or others

[chrome beacon]

Make some abstraction or use reflection

[lethal coral]

I am

[obsidian drift]

Would this be correct?

private class Test extends Skeleton {

                public Test(net.minecraft.world.entity.EntityType<? extends Skeleton> entitytypes, Level world) {
                        super(entitytypes, world);
                }
        }

Level level = ((CraftWorld) Bukkit.getWorld("world")).getHandle();
Test test = new Test(net.minecraft.world.entity.EntityType.SKELETON, level);
test.teleportTo(-3, 70, 6);

[chrome beacon]

Yes. You can call setPos in the constructor though if that's easier for you

Looks like it can't find a plugin

Specify the exact maven plugin dependency

[winter scarab]

        if(configSec == null) return;
        if(configSec.getList("list") == null) return;
        configSec.getList("list").remove(piece);```
according to my ide, how can .remove() possibly be NullPointerException if ive accounted for literally every variable to be null?

[quaint berry]

A plugin called lint

[chrome beacon]

^^

[quaint berry]

Quick question, How do I make a plugin pause for 2 seconds?

[chrome beacon]

Your IDE doesn't know that it won't return null the second time

[chrome beacon]

?scheduling

[undone axle]

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

[winter scarab]

what do you mean by the second time

if it checks everytime beforehand?

[quaint berry]

It can't find itself

'lint' in the current project

[chrome beacon]

You call getList twice

[winter scarab]

so i need to make it a variable to keep the same instance?

[chrome beacon]

Yes

[winter scarab]

any other ways? i will have to do this with quite a lot and rather not

[chrome beacon]

You can just ignore that warning

[winter scarab]

what about the assert statement?

[quaint berry]

I wouldn't know since I'm not the best but I get the same error when I don't reference the plugin instance

Neither

[chrome beacon]

Did you add the maven repo for that plugin

and did you follow the installation instructions

[winter scarab]

if there should be no way of a NPE occuring with what i have going, is it ok to suppress null warnings in specific classes i know it will especially flag

[chrome beacon]

If you know your IDE is wrong you can ignore it

[obsidian drift]

The entity doesn't seem to spawn, no error in console or anything

[chrome beacon]

Call setPos

in the constructor

[obsidian drift]

I have this

private class Test extends Skeleton {

                public Test(net.minecraft.world.entity.EntityType<? extends Skeleton> entitytypes, Level world) {
                        super(entitytypes, world);
                        this.setPos(4.0, 72.0, 12.0);
                }
        }

[chrome beacon]

also did you actually spawn it with level.addFreshEntity

[obsidian drift]

Oh... forgot that

[tawdry python]

Does anyone know how I can create a world with only plaints biome and only bedrock on layer 1? a normal world

[obsidian drift]

seems to be working well now, thanks

[quaint berry]

Your mean this?

Is there an equivalent to Thread.sleep(5) but for spigot?

[tawdry python]

Yes, but then I can't make a normal world with only bedrock on layer 1, not from 1 to 5, I think it's only programmable that I can do that

[quaint berry]

Since everything else is some weird indent

[quaint berry]

I heard that datapacks are more suited for this type of thing

[quaint berry]

.

[chrome beacon]

Use the scheduler like I linked earlier

[quaint berry]

I had a look but I'm special

[obsidian drift]

How can I create a pathfinding goal for an entity? For example following a player

[chrome beacon]

You can take a look at the existing goals

[supple elk]

Does anyone know how to stop a player moving in a boat?

I've tried something like this

[main dew]

World#notifyAndUpdatePhysics anyone know how work flag in this method? 😅

[quaint berry]

If you had many of these it looks like it would be a pain

[chrome beacon]

Well that's what you need to do

[supple elk]

but it kinda just teleports the player on to the top of the boat

rather than putting them in it

[quaint berry]

Oh

[glossy venture]

maybe like player or entity move event and cancel that

[supple elk]

I'm using VehicleMoveEvent

which is not cancellable

[glossy venture]

bruh

[chrome beacon]

NMS?

If so there should be a class with constants you can use

[main dew]

Yea

[chrome beacon]

Don't remember the old name

[eternal oxide]

?stack

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[quaint berry]

The whole server stopped when I did this

[glossy venture]

how

show your code

[chrome beacon]

Sounds like you still have thread sleep somewhere

[quaint berry]

Bukkit.getScheduler().scheduleSyncDelayedTask(myPluginInstance, () -> {
                ((Player) sender).teleport(finalLocation);
                Location finalLocationAbove = ((Player) sender).getWorld().getBlockAt(blockX, blockY + 10, blockZ).getLocation();
                ((Player) sender).getWorld().spawnParticle(Particle.EXPLOSION_HUGE, finalLocationAbove, 1);
                sender.sendMessage(ChatColor.GREEN + "Teleporting...");
            }, 10L);

[main dew]

And I don't understand

[glossy venture]

the code surrounding it?

[chrome beacon]

?paste

[undone axle]

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

[glossy venture]

because that will not stop a server

[quaint berry]

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

:D

[main dew]

On what version you write?

[quaint berry]

1.19

[chrome beacon]

isChunkGenerated uses chunk coords

Not regular ones

Also getBlockAt will load the chunk

[glossy venture]

think your position choosing code might be a little slow, you can automatically make random generate between a min and max using

int randInt(int min, int max) {
    return random.nextInt(max - min) + min;
}

[quaint berry]

It'll be fine

But

The server stops for 10 second E.i. The time I specify

[glossy venture]

because youre loading a chunk every position check i think

getBlockAt(...)

[chrome beacon]

^^

[glossy venture]

do the isChunkGenerated check first

with the correct chunk coords

[glossy venture]

also youre not specifying 10 seconds there, rather 10 ticks

[main dew]

if (!(sender instanceof Player p)) { return true; } you should use it

[glossy venture]

1 second == 20 ticks

10 seconds = 200 ticks

thats what you want in the value

for scheduleSyncDelayedTask

[opal juniper]

generics are kinda cool

[glossy venture]

yeah

[chrome beacon]

Try looking at the DFU and you'll never want to see Generics again

[opal juniper]

i do not want to see that

i err - yeah

[spare prism]

Hello. I want to display info below player's name. Why doesn't my code work?

    public static void setUserLivesScoreboard(User user) {
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        Scoreboard scoreboard = manager.getNewScoreboard();
        Objective objective = scoreboard.registerNewObjective("name", "dummy", "lives");
        objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
        objective.setRenderType(RenderType.INTEGER);
        objective.getScore("lives_team").setScore(user.getLives());
        Team team = scoreboard.registerNewTeam("lives_team");
        team.addEntry(user.getPlayer().getName());
    }

[chrome beacon]

Use the main scoreboard or set the players scoreboard to the new one you created

[spare prism]

Wouldn't everyone have the same info?

[chrome beacon]

?

ah yeah

[shadow zinc]

how do I check how many items are in players inventory?

[spare prism]

I want to display the lifes count for every player

[chrome beacon]

Either create a team for each player or set the players scoreboard

You probably want a team for each player

[sharp flare]

how many or what items they have?

[spare prism]

Can you show an example, pls? Or is this one correct?

    public static void setUserLivesScoreboard(User user) {
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        Scoreboard scoreboard = manager.getMainScoreboard();
        Objective objective = scoreboard.registerNewObjective("name", "dummy", "lives");
        objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
        objective.setRenderType(RenderType.INTEGER);
        objective.getScore("lives_team").setScore(user.getLives());

        Player player = user.getPlayer();

        Team team = scoreboard.registerNewTeam("lives_team_" + player.getName());
        team.addEntry(player.getName());
    }

[shadow zinc]

how many of any item

[chrome beacon]

Yeah that's fine

You might run in to errors if the team already exists though

[sharp flare]

#getInventory#getContents

[chrome beacon]

also make sure to remove teams when they aren't needed

[shadow zinc]

thats contents not size

[spare prism]

ok, I'll try that, ty

[shadow zinc]

and .length doesnt work

[sharp flare]

well there are stackables

[shadow zinc]

just how many slots are taken up

[sharp flare]

thats why you get the contents first

[chrome beacon]

hm actually what are you using the team for?

[sharp flare]

oh

[shadow zinc]

of 54 slots assuming

shovel a dirt block and food should be three

[spare prism]

I want to display players' lives count (from the plugin) below their names

[chrome beacon]

No need for teams then

Scoreboard is enough

[spare prism]

Can you show an example?

[shadow zinc]

its to check if there is room in the inventory to add another item for auto pagination

[chrome beacon]

Just like you did above but skip creating a team

[sharp flare]

not sure if there are specific methods for that, but I would loop the contents and filter out empty slots

[spare prism]

I'm not too familiar with scoreboards 😦

[shadow zinc]

thats straight up filly

k

ill do that

[spare prism]

But every player has it's own lives count

[chrome beacon]

or not

Yeah

The problem is a player can only be in one team at a time

You might cause conflicts with other plugins if you're not careful

[spare prism]

wdym if I'm not careful?

[chrome beacon]

Example:
plugin a; Creates a team for name colors
Your plugin adds lives count; Name colors no longer work

Actually again we don't need a team for this. Just create an dummy objective for each player and set the lives of that

[spare prism]

like that?

    public static void setUserLivesScoreboard(User user) {
        ScoreboardManager manager = Bukkit.getScoreboardManager();
        Scoreboard scoreboard = manager.getMainScoreboard();
        Objective objective = scoreboard.registerNewObjective("name", "dummy", "lives");
        objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
        objective.setRenderType(RenderType.INTEGER);

        Player player = user.getPlayer();

        objective.getScore("lives_" + player.getName()).setScore(user.getLives());
    }

[hidden kestrel]

Hey guys
Why does
e.getAdvancement().getDisplay()
Throw a
java.lang.NoSuchMethodError: 'org.bukkit.advancement.AdvancementDisplay org.bukkit.advancement.Advancement.getDisplay()' error??????

[chrome beacon]

ugh I hate working with scoreboards

[spare prism]

me too 😵‍💫

[chrome beacon]

That's probably not going to work either. Just use an existing plugin like TAB and add your own PlaceholderAPI

[chrome beacon]

Looks like that method doesn't exist in the version you're running

[spare prism]

I need it to work in my plugin 🥲

[chrome beacon]

TAB is open-source go take a look at how it works I guess

[hidden kestrel]

But I'm running 1.19.1??

[noble lantern]

What version is your plugin developed on? If it compiles but doesnt run on the sever then you got something mismatching somewhere

[quaint berry]

Does anyone have any ideas for making a cooldown for a command?

Like methods for doing it

[hidden kestrel]

1.19.1

      <dependency>
          <groupId>org.spigotmc</groupId>
          <artifactId>spigot-api</artifactId>
          <version>1.19-R0.1-SNAPSHOT</version>
          <scope>provided</scope>
      </dependency>

Oh 1.19

but still

[noble lantern]

Store a HashMap of UUID/Long

Where long is the Epoch milli of the time they ran the command, look into the Instant class its really helpful for this

And where UUID is the players uuid

From there, just compare times and if time is == 30 seconds + the stored time then you know 30 seconds has passed, you can remove them from the hashmap and process the command right there

[eternal oxide]

Your server isn't 1.19 or its not Spigot

[noble lantern]

you know what it makes sense alex was talking about some issues with advancments on paper a few days back

[noble lantern]

@hidden kestrel

also those 2 minor versions could of had a method rename too, may be good to check javadocs or just fully upgrade both sides

[eternal oxide]

Its in both 1.19 and 1.19.1. Excactly the same https://hub.spigotmc.org/javadocs/spigot/org/bukkit/advancement/Advancement.html#getDisplay()

[noble lantern]

yeah likely on paper then

[eternal night]

heh @tender shard we found your breaking change 😅 ^

[slate delta]

How can show this screen with code ?

[echo basalt]

uh

setFreezeTicks

[slate delta]

thanks

[noble lantern]

well

it will freeze the player i think no?

and give damage?

[echo basalt]

uhhhhhhhhhhhhh

[noble lantern]

or is it just a packet for freeze

[echo basalt]

entity metadata packets then

[noble lantern]

yee

or you can just cancel damage from snow frost

that works too

[hybrid spoke]

since when does this exist

[echo basalt]

might have unintended consequences

[noble lantern]

ever since the powdered snow was added

[echo basalt]

1.17 iirc

or 1.16

somewhere like that

[noble lantern]

1.16 i think

i can check in a sec on 1.16

[echo basalt]

I feel like it's 1.17

[hybrid spoke]

tf

[echo basalt]

because entity metadata packet

[noble lantern]

i think so too

[hybrid spoke]

i never experienced this

[noble lantern]

its annoying

[hybrid spoke]

what does it do

[echo basalt]

had to shift all bit fields by 1

[noble lantern]

when you fall in it you can see shit

[echo basalt]

because we added a new field to all entity metadata

[noble lantern]

and it just freezes you and constantly damages you

[hybrid spoke]

ah

[noble lantern]

you find them in snowy biomes

[hybrid spoke]

but it looks cool

[noble lantern]

and you can randomly fall in them

yeah the hud for it is cool

[hybrid spoke]

could be some mmorpg thing

[noble lantern]

they need a fire one

[echo basalt]

you can do funky shit

[hybrid spoke]

back to the minecraft mmorpg server idea

[echo basalt]

with resource pack

one for barrier warnign, other for snow tick

[real blaze]

quick question, for the InventoryClickEvent, does setCurrentItem() set the itemstack before or after an item is moved to the cursor?

[noble lantern]

iirc doesnt that set the item currently clicked

[echo basalt]

setCurrentItem sets the item at the target gui

[noble lantern]

or last clicked

[echo basalt]

currentItem = gui item

cursor = cursor item (doesnt belong to any gui)

[noble lantern]

ignore me

[echo basalt]

and those are the values before the inventory changes

because the event can cancel

issa pain

[noble lantern]

inv api is a mess

[eternal ember]

if you set it just 1 tick below the max it doesnt damage the player

[slate delta]

that work ! , but a event exist for when player take damage because that for cancel ?

[real blaze]

well thats bad for my use case since I wanted to set item lore once a player cursor picks up an item, and setcursor is deprecated

[noble lantern]

wouldnt it still slow them tud?

[echo basalt]

getView().setCursor

[eternal ember]

it does

[noble lantern]

Yeah it may likely be unwanted

[echo basalt]

entity metadata packets it is

do you want protocollib or nms?

[real blaze]

im new to this so getView() gets the viewer of the view where the click occurred? I was kinda confused with that and getViewers()

[echo basalt]

it returns the whole inventory view

top and bottom inv, whos the viewer

whats the cursor etc

[noble lantern]

can confirm its a 1.17 thing

its not on 1.16

back to building my reactor

[real blaze]

alright that makes sense, thanks

[hybrid spoke]

what a weird name for npc pathfindings

[echo basalt]

WalmartPathfinder

[noble lantern]

nah its my mekanism reactor

i got tired of staring at a ide for 14 hours

fucking with packets

[hybrid spoke]

do you still have the walking strategy?

[echo basalt]

I might need to code A* into minecraft

[noble lantern]

ofc

[real blaze]

I assume that HumanEntity can be casted to Player with no issue?

[echo basalt]

burch help me with that shit

zombies keep trying to walk through walls

[noble lantern]

use olis with my path strat

[hybrid spoke]

https://github.com/olijeffers0n/PatheticAPI

[noble lantern]

well they wont target through walls sadly

the path strat will give up if no path found

[echo basalt]

does it support trapdoors

[chrome beacon]

Usually yes. It might be worth to do an instanceof check

[noble lantern]

like opening doors?

thats all on you

[echo basalt]

no

[noble lantern]

but yeah it does

[echo basalt]

I mean

map is full of trapdoors

it trips AI up as wel

[noble lantern]

uhhh

cipher question

or ollie

[hybrid spoke]

well, i've never tested trapdoors or any kind of that

[noble lantern]

i never tested that

[hybrid spoke]

but i guess if its open 🤔

[noble lantern]

LOL

let me get the path strat code

do note

[hybrid spoke]

@opal juniper ever tested trapdoors?

[noble lantern]

its before you added instance based rules

[opal juniper]

nope

[hybrid spoke]

yeah i would've to adjust it anyways

[echo basalt]

I wonder how it would act here

[hybrid spoke]

since we started to implement rulesets

[opal juniper]

in what way doe? like walking over or thru

[noble lantern]

my path strat should go up the stairs

[hybrid spoke]

probably determine doors and trapdoors as solid blocks

[opal juniper]

i think they would be OTHER

[noble lantern]

by default tho it may do something whacky

[hybrid spoke]

as what does bukkit state trapdoors etc

solid?

[opal juniper]

oh yeah i made quite a big diff the other day

so gl merging burchard ahahaha

[echo basalt]

it would bug here then

[noble lantern]

hmmmmmmm

[hybrid spoke]

you could test it

[noble lantern]

no

not mine

should be fine

default should be too

[echo basalt]

I mean

default tries to do stupid shit

[noble lantern]

?paste

[undone axle]

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

[noble lantern]

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

This tries to avoid falling off cliffs and will try to avoid lakes whenever possible by an offset of 2 blocks

May not be best for performance but its async

[echo basalt]

zombies pathfind up here and then get stuck because they can't yeet through barriers

instead of going around

like how tf

[noble lantern]

ollies should be fine with barriers

[hybrid spoke]

yeah it is, but if its the default it will also try to find holes in the barriers

or try to go above it if there is a hole

[noble lantern]

oh shit

speaking of that cipher

[noble lantern]

it needs 2 block high handling is all

then its perfect 👌

thats easy to add tho

[echo basalt]

there are literally no holes

[hybrid spoke]

so probably a "can stand here"

[echo basalt]

they spawn in a corner

and pathfind there

to just look at the player

[hybrid spoke]

thats fine

[echo basalt]

and taunt it

this is a damn zombies map

[noble lantern]

only issue with my strat

it wont walk on 1x1 spaces

its scared to

like in the air

wait no

i fixed that

nvm

only issue i had with ollies pathfinding is sometimes

the blocks dont nail to the floor

so with packet based npcs they fly lol if your not handling physics

[echo basalt]

these stupid mfs

have a tracking range of 200 blocks

and still just decide to die

[noble lantern]

200??????

[echo basalt]

yeah

[noble lantern]

thats HUGE

i barely do over 40

if its over 40

[echo basalt]

they also respawn if the target is further than 70 blocks

but what if there's no spawn point available

[noble lantern]

take entity -> teleport it to random location offset by 5-15 blocks

[echo basalt]

🤔

[noble lantern]

oh okay

nvm

[echo basalt]

I've been working on this damn zombies project for 2 months

we had a meeting last week

guy died, fell through the floor and crashed the server

so we had another one 2 days ago fixing stuff

and the map would close doors you opened

if you got too far

👍

[noble lantern]

honestly you might want a custom strat for something like that

even different than mine

[echo basalt]

I mean

I just have somewhat modified pathfinders

[noble lantern]

if you use ollies lib***

sorry

[echo basalt]

more like the block checker itself

I'd rather do like 3 hours of NMS reworking to get this to work

than to write a pathfinding algo

[median trench]

Is there a way to set a passenger entity leashed to a player? When I leash an entity and set it riding another entity, it removes the leash (with nms)

[noble lantern]

you dont need to write an algo

[echo basalt]

or tune an algo

[noble lantern]

did you even see the pathfinder paremeter i sent lol

i already did that for you

[noble lantern]

dot

[echo basalt]

I mean

I don't care about cliffs

[noble lantern]

yeah so just remove the if

//

[echo basalt]

also I'd need to change the snapshot manager

because clientside block

[noble lantern]

oh

jesus fuck smh

100x more complicated now

[echo basalt]

and also do some pathfinding because trapdoors

and their fancy aabbs

[noble lantern]

@opal juniper make it work on client side blocks 😄 (joking btw)

[noble lantern]

if it doesnt work on trapdoors it would be a rather easy fix

[echo basalt]

some trapdoors are closed

some are open

I use some as walls

others as decoration

[echo basalt]

api: https://gist.github.com/IllusionTheDev/b38fb7f00ef5a565f886931b631072c5

[noble lantern]

try and see

youll never know without trying but

you have client side blocks

so it makes it way more complex

[opal juniper]

lol, thats not possible right

you dont know what blocks they have

[noble lantern]

it is if they make theyre own isValid handler

and store the blocks each player has but

jesus so much work

[opal juniper]

mfw you send API requests to the client :))

[echo basalt]

you can make an interface

[echo basalt]

if you look at the gist

I do track what players see what

You can make an interface which is like

[opal juniper]

but that is reliant on your plugin being the only one faking blocks as well

[noble lantern]

well in most cases it is

tbf

[echo basalt]

public Material getTargetType(LivingEntity target, Location location) { return location.getBlock().getType(); ]

[noble lantern]

no Locations

async

[echo basalt]

fuck

[noble lantern]

PathLocation

[echo basalt]

I mean

[noble lantern]

BukkitMapper.toPathlocation(location)

[echo basalt]

you gotta pathfind through something

so you'd be checking blocktypes regardless

[noble lantern]

ChunkSnapshots

[echo basalt]

just add method to override that getter

or inject through

[echo basalt]

override the snapshot idfk

my api is thread-safe afaik

[hybrid spoke]

or pass in your own PathBlocks

[noble lantern]

^

it takes x y z doubles

so as long as you have the location ur fine

[echo basalt]

why doubles

[noble lantern]

ints whatever the fuck

idk

i didnt write i just used tf out of it

[hybrid spoke]

https://github.com/olijeffers0n/PatheticAPI/blob/master/pathetic-api/src/main/java/xyz/ollieee/api/wrapper/PathBlock.java

[noble lantern]

abused the poor thing so hard

[hybrid spoke]

and location takes doubles

[noble lantern]

okay i am making a suggestion

[echo basalt]

ehhh okay I'll try

[noble lantern]

new PathBlock(1, 1, 1, PathBlockType.SOLID)

[hybrid spoke]

world goes brr

[noble lantern]

wait

why does it need world

[hybrid spoke]

where else would the location be

[noble lantern]

it already has it no? for the pathfinder?

[echo basalt]

okay now

how the fuck do I make a zombie follow that path

without setting velocities every tick

[noble lantern]

okay so

[hybrid spoke]

pathblocks holds a pathlocation which holds 3 doubles and a pathworld

[noble lantern]

its 1 block movements

so uh

huh

uhhhh

[opal juniper]

thats a point actually

hmm

i think they are used in WorldDomains

but i forget

[echo basalt]

top tier pathfinder api

but you can't apply pathfinders to mobs

[noble lantern]

Couldnt Pathfinder just hold the pathWorld?

[echo basalt]

[noble lantern]

ik

[hybrid spoke]

not at the current state

[noble lantern]

that was most of my time spend using it

[noble lantern]

ah kk

[hybrid spoke]

i already thought about making the pathfinder instance based as well

and passing in 2 locations

[echo basalt]

worst part is like

the target is an entity

so you'd need to recalc path every tick or something

[noble lantern]

I like the PathFinder#pathfind(to fromt) imo

[echo basalt]

but nms also does that

[hybrid spoke]

yeah also recycling doesnt sound bad

[echo basalt]

and all the concurrency stuff to make it sync <-> async

will give some delay

[noble lantern]

i recalc every like 10ish ticks but im not in a small confined area

[noble lantern]

Can make PathFinder hold certain settings too

[opal juniper]

they are used for world domains @noble lantern
https://github.com/olijeffers0n/PatheticAPI/blob/bf3374490bed547ae33677e441551ca99aaf4e7a/pathetic-model/src/main/java/xyz/ollieee/model/snapshot/SnapshotManagerImpl.java#L33

[noble lantern]

that way you dont need to re-initialized

[echo basalt]

I can't recalc every 10 seconds here

too confined

[noble lantern]

10 ticks*

[noble lantern]

Ahh

that could esily be put in pathfinder tbf

your never gonna switch world like pathfinding like that lol

unless you add support for portals

[hybrid spoke]

yeah i just noted that down

[opal juniper]

yes he did

[noble lantern]

yeah that part is done

[opal juniper]

my code isnt working somewhere here lol

(not pathetic)

[hybrid spoke]

you are pathetic

[opal juniper]

https://tenor.com/view/roasted-oh-shookt-gif-8269968

[hybrid spoke]

it looks like the dude in the front is spawning over and over again

[opal juniper]

it sysouts, but then failes before the second

[opal juniper]

true dat

no error tho, just silent

so apparently sender is null causing an NPE

who would have known

not me cause java stupid and errored silently

[noble lantern]

{{ }} ??

tf

[opal juniper]

ye its how the initialisers work

[noble lantern]

oh so you can initalize it like that without needing to override

didnt know that

everytime i tried it it just gave me options to override

[echo basalt]

don't

it's a hacky ass method

[opal juniper]

yes and i like it

[echo basalt]

makes a whole anonymous class

[opal juniper]

yes and i like it

:)

[gray merlin]

Is there a way to create an Entity or CraftEntity object or something of the sorts? I have some NBT i'd like to add to an entity before it is placed in the world, so it spawns with everything included.

[opal juniper]

wait wudaheq

[echo basalt]

new CraftEntity

type thing

[opal juniper]

its not sending some data eventhough i set it to

^^

[eternal oxide]

do yoru changes in the Consumer

[echo basalt]

not really that safe conestly

[chrome beacon]

It should be

[gray merlin]

Will look at this

[echo basalt]

I mean

the new entity

stuff

consumer is cool

[gray merlin]

Oh, I see. We can just pass in the NBT at spawn-time.

Thank you, that also works!

[dense pine]

For some reason this exception crashes my plugin

ive got pom.xml and jar libraries so idk why it cant find it

this class exists in the jar

[eternal oxide]

These look like manually added jars, not Maven

[echo basalt]

do you see a system path elgar

they look fine

but are the deps shaded

[dense pine]

i tried maven, jars, both at the same time

[echo basalt]

🤔

I'm still mad this exists

[eternal oxide]

Don;t use jars if you are using maven, unless you are forced to 3rd party jar.

if You manually add jars Maven will not see them.

allow Maven to do what its supposed to do

add scopes to your dependencies

[dense pine]

and what is that sir?

removed jars and replaced with maven only

[eternal oxide]

good

anything which is already on yoru server you can set as <scope>provided</scope>

[real blaze]

public void diamondDropListener(ItemSpawnEvent e){

            item.getItemMeta().setLore(null);

So this code block attempts to remove lore from items upon becoming an item entity

doesnt seem to work?

[dense pine]

didnt fix anything still class not found

did you @eventhandler

[real blaze]

its there

[eternal oxide]

did you build using Artifacts or teh maven package menu?

[echo basalt]

meta is a copy

you gotta setMeta as well

[tardy delta]

for (short s = ...) 💀

[azure island]

that's bad?

[echo basalt]

micro optimizng ram

[tardy delta]

not really useful

[echo basalt]

like

man's micro optimizing while having bigger issues

like nesting

[real blaze]

ah right java is always by value not reference

[echo basalt]

and lack of item utilities

[tardy delta]

no getMeta() always returns a copy

[real blaze]

or well i called a getter

@dense pine If you're developing for 1.16 or higher you can add com.fasterxml.jackson.core:jackson-core:2.13.3 to the libraries section in the plugin.yml or you can shade the dependency using the maven shade plugin

https://maven.apache.org/plugins/maven-shade-plugin/examples/class-relocation.html

[real blaze]

alright so here's a new problem which im not sure how best to be done:

calculating how many of x item was used in a craft that a player did

Checking CraftItemEvent, the getRecipe() method returns a recipe that has getResult(), which isn't what I'm looking for

[eternal oxide]

another loop reducing the radius

[real blaze]

Is the best method of doing this like, check the result and make a big switch statement with all possible recipes this item can be used for, returning the quantity of the item used?

[dim bronze]

What are you actually trying to achieve

[real blaze]

essentially im just trying to keep a scoreboard of diamonds that have a lore tag with the player name on them

and i want players to lose score if that diamond is crafted with

so i need to detect 2 things:

• when a player crafts, did they use a diamond in the recipe?
• if so, how many diamonds to reduce from the scoreboard?

[eternal oxide]

In the https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/CraftItemEvent.html you can see what is in the inventory when the item is removed

you only have to watch for your specific diamond

[real blaze]

it isn't a specific diamond though, its any arbitrary diamond

[eternal oxide]

I thought you just said, if they craft using a diamond with a specific lore with their name on it?

[real blaze]

ah right, i guess i should explain that any diamond that a player picks up / picked up with a cursor gets tagged

essentially every possible way you gain a diamond in the player inventory will tag it and contribute to score

[dim bronze]

I think the easiest way would be what ElgarL suggested, check the top inventory, cast it to a CraftingInventory and then check its matrix for your diamond

one thing you would have to be careful of is checking whether the player has clicked normally to craft one or shift clicked to craft multiple

[eternal oxide]

Yeah, shift clicking is a pain

[dim bronze]

realised my definition wasn't really correct*

[dense pine]

i dont have lbiraries section in my pom

[tardy delta]

in your plugin.yml

[dense pine]

ah

[real blaze]

perhaps one easy solution would be to simply remove the score if a player places diamonds in the crafting grid

sorry

[dense pine]

im blind sorry xDF

[dim bronze]

That's the new way of adding dependencies however it's been buggy for me sometimes

[dim bronze]

probably more hassle because a player could decide not to craft the item, and there's a lot of ways they could bail out of the inventory

leaving the game, inventory close, removing the items from the grid etc.

[real blaze]

i do have the following measures in place:

• upon an item becoming an item entity, score is removed
• upon clicking on an item in an inventory, if it isnt marked as yours, mark and gain score

[eternal oxide]

Does the player have to keep the diamonds in their inventory to keep their score?

[real blaze]

nope

[eternal oxide]

in that case, why not update teh score every 60 seconds. Count how many diamonds in each players inventory

no messing about with totals and crafting then

[real blaze]

well that wouldnt count diamonds in chests no?

[eternal oxide]

it would not

[dim bronze]

the player doesn't need to keep them in their inventory

[eternal oxide]

Sorry I mis read and thought they had to carry them

[real blaze]

this would be a lot easier if it was just carrying lol, could've been the job for a datapack

[dense pine]

ok the libraries worked but how do i shade dependencies so ill know if ever need to

thanks btw

[dim bronze]

The link I sent in the reply sort of shows you

https://maven.apache.org/plugins/maven-shade-plugin/examples/class-relocation.html

[cunning canopy]

Wth is nms?

[dim bronze]

how are you currently building your jar? @dense pine

[eternal oxide]

net.minecraft.server Mojang code

[dense pine]

i include project artifact while building

[cunning canopy]

So vanilla server?

[eternal oxide]

vanilla source.

[dim bronze]

yes but are you using the command line / maven panel in intellij or are you using intellij build artifacts?

[tardy delta]

does anyone knows if you put a plugin in the plugins/update folder and you reload the server instead of restarting, the plugin also enables?

[dense pine]

inteliij

[real blaze]

one solution would be:

• get crafting result
• get a case statement for each recipe that uses diamonds and assign a value of diamonds used
• remove quantityUsed * itemstack.getamount() of score

However, its impossible to know if a player crafted a Firework that used a diamond

[tardy delta]

use maven/ gradle

[dim bronze]

there's probably a way to do it through intellij but I can't check at the moment. If you wanted to shade the dependencies into the JAR in the future you would need to run mvn package either through intellij maven panel or command line

The link I sent also shows relocating the dependencies which is good practise so you aren't using a dependency in someone elses plugin

[eternal oxide]

Right side of your screen, maven window -> lifecycles -> package

[dense pine]

i think i got it

[dim bronze]

that looks like it's done it

jar is then inside target folder
