[waxen plinth]

Case sensitivity is specific to strings

[patent horizon]

yeah

[waxen plinth]

If you want to check that, you should store the values in a set

[patent horizon]

it's a list of strings

[waxen plinth]

And call toLowerCase() before inserting, and also before checking contains

HashSets are ideal for this

[patent horizon]

ok awesome

[opal juniper]

i guess it just assumes that the dev knows cause they put it there

[waxen plinth]

But keep in mind they are unordered, cannot contain duplicates, and cannot be indexed

[waxen plinth]

Well, config is a big hash map

To my knowledge it loads everything in at once when you load config and keeps it in memory

It must make the distinction when it's loading

[opal juniper]

oh yea true

[waxen plinth]

The easiest way is probably to store it in a long, and if it's with int bounds then you convert it to int

[opal juniper]

makes sense

[floral pewter]

Hey. I've been getting strange runtime errors related to PathfinderGoals ever since the update to 1.17, I believe it has to do with obfuscation maps having missed something since I've seen issues like https://github.com/PaperMC/paperweight/issues/24. This is the problematic code I'm running inside a custom Villager class:

    @Override
    protected Brain<?> makeBrain(Dynamic<?> dynamic) {
        //Initialise the brain with our own custom goals
        Brain<net.minecraft.world.entity.npc.Villager> brain = this.brainProvider().makeBrain(dynamic);

        this.goalSelector.addGoal(0, new FloatGoal(this));
        this.goalSelector.addGoal(1, new PanicGoal(this, 1.4D));
        this.goalSelector.addGoal(2, new WaterAvoidingRandomStrollGoal(this, 1.0D));
        this.goalSelector.addGoal(3, new LookAtPlayerGoal(this, Player.class, 6.0F));
        this.goalSelector.addGoal(4, new RandomLookAroundGoal(this));

        return brain;
    }

The error I'm getting is

java.lang.NullPointerException: Cannot invoke "net.minecraft.world.entity.ai.navigation.NavigationAbstract.d(boolean)" because the return value of "net.minecraft.world.entity.EntityInsentient.getNavigation()" is null
    at net.minecraft.world.entity.ai.goal.PathfinderGoalFloat.<init>(PathfinderGoalFloat.java:14) ~[patched_1.17.1.jar:git-Paper-249]

[sullen marlin]

You're not using spigot

[floral pewter]

The goals in question are taken down from the chicken class, so they work internally

I've tried with spigot as well. Give me a second and I'll get the error from that as well

The error returned by Spigot remains the same.

java.lang.NullPointerException: Cannot invoke "net.minecraft.world.entity.ai.navigation.NavigationAbstract.d(boolean)" because the return value of "net.minecraft.world.entity.EntityInsentient.getNavigation()" is null
    at net.minecraft.world.entity.ai.goal.PathfinderGoalFloat.<init>(SourceFile:14) ~[spigot.jar:3236-Spigot-6c1c1b2-6719d1f]

[sullen marlin]

You should probably be initialising goals in the goal initialisation method, not the brain one

[floral pewter]

I'll have a crack at that

[floral pewter]

I came to the conclusion that the villager class as of 1.17 doesn't use goals, but activities exclusively - which is why the getNavigation() method returned null

Changing the base entity to chicken/pig made it work

Now I have to figure out how to emulate goal behaviour with activities

Thanks for your help!

[patent horizon]

how do i use functions across different classes without making them static

[ivory sleet]

inject instances

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[ivory sleet]

yeah check out that one

[chrome beacon]

You cannot modify a list that you're looping

Loop a copy

[vague oracle]

Could be a dumb question but, which is better to do a bungee command or a server side command?

For example a command to change the MOTD on redis so it doesn't really matter, just which one is the better practice?

[chrome beacon]

Break exists the loop

Try it and see

[chrome beacon]

MOTD is generally handled by the bungee so a bungee command

[vague oracle]

event.getResponse().setDescriptionComponent(new TextComponent(Chat.colour(bungee.getApi().getMOTD()))); Is how it works, it was an example command. I was just asking is it better to put a command in the bungee plugin or a server plugin

[chrome beacon]

The one best suited for the command is what you should use

As I said for MOTD a bungee command would be better

[atomic gyro]

I'm having issues with the Loot Table / Loot Tables API in Spigot. Anybody know how I can convert a LootTables to a LootTable?

[eternal oxide]

LootTables.ZOMBIE.getLootTable()

[atomic gyro]

oh its that easy. thank you!

is it possible to set a default loot context? null would throw an error, but I'd like to define it without any modifiers.

[eternal oxide]

What do you mean?

You can specify the LootContext by calling LootTable.fillInventory

[atomic gyro]

Yes, but how would I specify it? On the JavaDoc, it's got a bunch of getter methods but I can't seem to figure out how to set a default.

[eternal oxide]

what do you mean "specify it"?

it has a builder

[atomic gyro]

Oh, how do I use the builder?

Never had to work with one before.

[eternal oxide]

Read javadoc https://hub.spigotmc.org/javadocs/spigot/org/bukkit/loot/LootContext.Builder.html

[atomic gyro]

Will do, thanks.

[eternal oxide]

Its teh same as all builders Builder(Location) .killer(killer) .etc .build();

[atomic gyro]

Thank you, I'll be using it soon.

When using .getLootTable(), does it return a memory address or the proper json file?

Since it's getting a key, would it be the file location of the loot table? (eg; data/loottables/whatever)

[eternal oxide]

it returns a LootTable Object

[atomic gyro]

Is there any method of reading a LootTable object?
For example, if I wanted to list the possible contents of a loot table as Strings, is there a method of converting the LootTable object into a readable state?

[eternal oxide]

You can read the javadoc as well as I can https://hub.spigotmc.org/javadocs/spigot/org/bukkit/loot/LootTable.html

[atomic gyro]

I'll have to do a bit more reading. I appreciate your help!

[proud basin]

can someone confirm for me that this is red 0xFF0000

[paper viper]

https://www.w3schools.com/colors/colors_hexadecimal.asp

yes

[proud basin]

hm weird

[eternal oxide]

RGB

[quaint mantle]

how can i get a block entity that's already placed and get the contents? like an item frame with a stick

[eternal oxide]

Entity != Block.

[proud basin]

so if I used 0xFF0000 it should turn out red

[quaint mantle]

I can't remember what they're called so i meant like block entities like item frames and paintings

[eternal oxide]

if you only have the location World#getNearByEntities

[quaint mantle]

ohh ok, but then how would i get the item that's in the frame?

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/ItemFrame.html

[quaint mantle]

oh, thank you!

[proud basin]

Elgar please explain to my why it's not giving me red

[quaint mantle]

Does anyone know how to import an entire function?

[paper viper]

static imports?

[eternal oxide]

what colour are you getting? and is this OpenGL or MC?

[quaint mantle]

this

i`m using eclipse for example

[proud basin]

im getting invisible

mc

[olive valve]

hello! how can i it so i can have two command arguements. like args[0] and args[1] bc i made a command with two arguements but it only ran args[0], can anyone help??

[eternal oxide]

I can see it being possible in GL but not MC. RGB has no transparency

unless you are using something which only supports the fixed MC colour pallet

[proud basin]

all I know is that it doesn

't show up

oh wait

I know

[quaint mantle]

do i get it like this? ItemFrame frame = (ItemFrame) world.getNearbyEntities(new Location(world, 0, 40, 0), 0, 40, 0); something about it feels wrong though

like the two sets of coordinates

[eternal oxide]

second is not cords, they are distances

[olive valve]

hello! how can i it so i can have two command arguements. like args[0] and args[1] bc i made a command with two arguements but it only ran args[0], can anyone help??

[eternal oxide]

It returns a collection, so no casting it to an ItemFrame

[proud basin]

ok idk

elgar

I thought maybe GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F); would help it but no

[proud basin]

Does it need to be 9 characters?

[eternal oxide]

MC is 6 xx,xx,xx RGB

oh so not MC, its is GL

[proud basin]

no

[eternal oxide]

you just posted above GL code

[proud basin]

yeah

but its not

[eternal oxide]

a glColor4 which has an alpha channel

[proud basin]

I just wanted to see if that would fix it

[quaint mantle]

How do I import all this automatically into intellij?
This image is from the eclipse to show as an example. I write switch and use Ctrl+Space and it imports everything.

i don't think that you're thinking of the same import i'm thinking of..

[quaint mantle]

I just want to import this quickly into intellij

without having to write everything down.

i'm not too sure if eclipse has them but maybe use a plugin for that if it does, also, i think importing would be pulling classes to use elsewhere in your project using import

[eternal oxide]

https://www.jetbrains.com/help/idea/auto-completing-code.html#statements_completion

[proud basin]

so

[quaint mantle]

oh wait i thought they meant eclipse oops

[proud basin]

whats the other issue

any other color that has 9 characters work

[eternal oxide]

9 characters?

[olive valve]

hello! how can i it so i can have two command arguements. like args[0] and args[1] bc i made a command with two arguements but it only ran args[0], can anyone help??

[proud basin]

yeah

like 0f0f0f0f0f0f0f

[eternal oxide]

what are you using this in?

as thats not a valid MC color

[proud basin]

yes it is

0x90000000 this works

[eternal oxide]

that is not a Minecraft color. Its hex and will probably display something but MC is 3 Hex codes

[proud basin]

it is

it does display

but red doesn't

[eternal oxide]

https://colorswall.com/palette/3847/

You are throwing values in there but its nto correct

[proud basin]

hiow

0xb02e26

doesn't work

[eternal oxide]

then you are not using MC color codes

[proud basin]

im not using spigot

opengl

[olive valve]

hello! how can i it so i can have two command arguements. like args[0] and args[1] bc i made a command with two arguements but it only ran args[0], can anyone help??

[eternal oxide]

I'm going to stop helping you if you keep telling me one thing and then changing your mind.

[quaint mantle]

<command> <arg0> <arg1> etc.

[proud basin]

im working with forge man

[eternal oxide]

show some code so we know what you are trying to do

[proud basin]

so

open gl

[eternal night]

A natural assumption in the spigot development help channel

[eternal oxide]

I specifically asked earlier if you were using MC colors or GL

[olive valve]

            if(args[1].equalsIgnoreCase("2")){
                //run code here
            }
        } else {
            p.sendMessage("§cCannot find enchantment:§c" + args[0]);```

[eternal oxide]

are you testing your args.length?

[olive valve]

testing??

[eternal oxide]

Do you check there are 2 args in teh command that was entered?

if(args.length == 2)

[olive valve]

ohhhhh right.. thanks for helping me

[eternal oxide]

show the actual OpenGL code you are trying to use colours in

[proud basin]

public static void drawRoundedRect(int x, int y, int width, int height, float radius, int color) {
        float f1 = (color >> 24 & 0xFF) / 255.0F;
        float f2 = (color >> 16 & 0xFF) / 255.0F;
        float f3 = (color >> 8 & 0xFF) / 255.0F;
        float f4 = (color & 0xFF) / 255.0F;
        GlStateManager.color(f2, f3, f4, f1);
        drawRoundedRect(x, y, width, height, radius);
    }

[eternal oxide]

wierd ordering.

but it has 4 entries which means it has an alpha channel

f1 "should" be the alpha. 0.0 would be opaque (visible)

GlStateManager.color(255.0, 0.0, 0.0, 0.0); - red

[proud basin]

yea

I wanna use hex though

[eternal oxide]

from a quick glance at that math it seems to be reversed

so 0x00FF0000

Not really awake but try 0xFF00

[proud basin]

nope

[eternal oxide]

what did FF00 do?

[proud basin]

invisible

[eternal oxide]

what about 00FF?

is this your method, or one you've taken from Forge?

Because that math looks so wrong

[proud basin]

mine

forge doesn't have this

otherwise I would of used it

[eternal oxide]

public static void drawRoundedRect(int x, int y, int width, int height, float radius, int color) {
        float f1 = (color >> 24 & 0xFF);
        float f2 = (color >> 16 & 0xFF);
        float f3 = (color >> 8 & 0xFF)
        float f4 = (color & 0xFF);
        GlStateManager.color(f2, f3, f4, f1);
        drawRoundedRect(x, y, width, height, radius);
    }```This should accept 0xFF0000

[patent horizon]

how can i set an entity's health in the EntityDamageEvent ?

[eternal oxide]

setHealth(Double)

[patent horizon]

sethealth isn't an available thing

[eternal oxide]

on an Entity it is

so long as that Entity is Damageable

[patent horizon]

would i have to check if the entity is damageable before setting health then?

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Damageable.html#setHealth(double)

[patent horizon]

idk but intellij says it cant resolve method "setHealth" in "Entity"

    @EventHandler
    public void onDamage(EntityDamageEvent event) {
        if (event.getEntityType() == EntityType.PLAYER) {
            if (event.getEntity().getWorld() == Bukkit.getWorld("lobby")) {
                event.setCancelled(true);
                event.getEntity().setHealth();
            }
        }
    }```

[proud basin]

now my other colours are messed up

also didn't work

[eternal oxide]

test if instanceof Damageable, cast and you have setHealth

[patent horizon]

yeah uh

[eternal oxide]

didn;t work? what did it do?

[patent horizon]

in morons terms?

im pretty new to java

[proud basin]

made it invisible also made all my colors black

[eternal oxide]

if (e instanceof Damageable) ((Damageable)e).setHealth(...)

[patent horizon]

does e = event or entity

[eternal oxide]

entity

[eternal oxide]

well if you already use that method for other colors you can;t change it

how are you calling it with other colors and its correct?

[proud basin]

DrawUtils.drawRoundedRect(this.x, this.y, this.x + this.width, this.y + this.height, 1, this.color);

yes

[eternal oxide]

Oh ok, still not awake. I forget its floats. 1.0 is max, thats why its divided

So GlStateManager.color(1.0, 0.0, 0.0, 0.0); should produce red

the method is accepting ARGB

which means I don;t see why its not working with 0xFF0000

[proud basin]

yeah

weird

What's another red

[eternal oxide]

like 0x7EFF0000 should be a faded red

[proud basin]

that works

do you know a shaded white?

[eternal oxide]

try 0xFFFF0000

that should be a transparent red

if not they have teh alpha inverted

[proud basin]

that is def not transparent

that is full on red

[eternal oxide]

then you have to provide an alpha of 1.0, so FF

[proud basin]

weird

[eternal oxide]

0x ARGB or 0xFF + R + G + B

[proud basin]

also do you know why I am missing the music assets?

[proud basin]

I have that?

[eternal oxide]

you just have to prefix any RGB with FF

[proud basin]

float f1 = (color >> 24 & 0xFF) / 255.0F;

see

[eternal oxide]

yes, but you have to provide that in your hex

[proud basin]

yea

[eternal oxide]

as its inverted

1.0 is giving you full opacity

[proud basin]

oh okay bump 🙂

[eternal oxide]

no clue. Didn;t really know what you are doing

[proud basin]

cmon

why not you should know

[eternal oxide]

Somethinh like skinning a client using Forge

[proud basin]

no

also it's kinda dumb on how ugly a custom font is when you are full screened

[eternal oxide]

they are taken from bitmaps so don;t scale well

[proud basin]

I can see that

I can't find a shaded white you got one?

google is pretty useless right now

[eternal oxide]

FFFFFF is full white, so add whatever alpha youwant on the beginning

[proud basin]

4?

[eternal oxide]

if you want full on white yes 0xFFFFFFFF

[proud basin]

what if I don't

[eternal oxide]

white is the presence of all colours, black is the absence of all

[proud basin]

shaded

[waxen plinth]

Anything where the R, G, and B components are equal will be grayscale

[eternal oxide]

so to move it towards grey reduce all three colours evenly

[proud basin]

F0FFFF

[eternal oxide]

keep your Apha FF

0xFF | AB | AB | AB

remember its ARGB, so you only adjust RGB

[proud basin]

Is there like a color picker for shades?

I won't remember this

[eternal oxide]

a better one https://rgbacolorpicker.com/

[proud basin]

ok

will try

[quaint mantle]

anyone know how to rotate falling blocks left-right

[proud basin]

velo?

[eternal oxide]

FallingBlocks are entities so you can set their yaw

setRotation

[quaint mantle]

@eternal oxide did not know that existed

thanks

is there a way to have them inherently turn around by themselves with NMS

or am i just going to have to resort to a scheduler

[eternal oxide]

FallingBlocks have no AI so you would have to do it manually

[quaint mantle]

i see, thank you

[proud basin]

What's more efficientRuntime.getRuntime().exit(); or System.exit(0);

[eternal oxide]

if you don;t care about file locks or corrupting data the first, if you want a clean exit the second

[proud basin]

ok cool

[eternal oxide]

The first will exit instantly. It will not wait for anything to finish

[proud basin]

Sounds like task manager end button

[eternal oxide]

worse

[proud basin]

how could it be worse

[eternal oxide]

If you use it you better not want to open that application again

odds are 50/50

its great if you are running docker or somethign and just want a quick exit

[proud basin]

kinda wanna test it

[torn oyster]

does System.exit(0); save?

[eternal oxide]

it will attempt a clean exit

so long as your code supports save on exit

[quaint mantle]

How to play a sound when the player hits someone with an arrow?

[eternal oxide]

as in a fired arrow?

or a left click hit?

[quaint mantle]

yes

[eternal oxide]

ProjectileHitEvent call a Player.playSound or World.playSound

[atomic gyro]

Can I call files from the minecraft.jar if I have the Key/Namespaced Key for them?

[ivory sleet]

wym

[atomic gyro]

I'm trying to call a loot table so I can read the items in it as Strings, and so far I've used

LootTables.ZOMBIE.getLootTable().toString()``` to get the Key for it. Can I access the loot table as a String/JSON file using this key?

[worldly ingot]

That's not exposed in the API. Shouldn't really be accessing the JSON file for it. No reason to

[atomic gyro]

How else can I view the contents of the loot table?

[atomic gyro]

Do you mean no reason to as in "there is another, easier way"? Or as in "there is no method to, and you shouldn't be doing it anyways."

[sullen marlin]

Loot tables are random and depend on various things

Its content isn't a simple concept

You could fill a dummy inventory and check its contents that way

But again, contents can change

[atomic gyro]

I thought loot tables had values in them, back when I tried doing datapacks/custom entities using command blocks.

It usually has multiple items, then a weight and drop count. The game then uses that table to determine the loot with a random seed. I was hoping to read the file that contained the weights and drop counts.

Something like this.

[sullen marlin]

Why?

?xy

[undone axle]

http://xyproblem.info/

[atomic gyro]

I'm currently trying to make a plugin that can read loot tables on the server by using /command (loot table name here) to view the loot table in an easier fashion, using inventories to display the items with names and lore based on their weights and drop chances overall.

Most of it should be if statements, math, and for loops, but this is the part that is really getting me tripped up.

[sullen marlin]

I think you'll find it more involved than you expect, there's a lot of different functions

But you'd have to read the file from the jar

Same way you read any file in a jar, getResourceAsStream

[atomic gyro]

Thank you, that really helps.

I'll be sure to mess with it more tomorrow and to read up on the JavaDoc.

If all goes well, hopefully some actual progress can be made :)

[atomic gyro]

I really like this btw thank you.

[quaint mantle]

does anyone know hwo to set an NMS falling block's type

[worldly ingot]

afaik you can't change it once it's been spawned

Thus why the API doesn't support it

[quaint mantle]

i meant when spawning it

ive actually got smth

might work

ill post it if it does 🙂

[waxen plinth]

Why are you spawning it with NMS?

Just spawn it with World#spawnFallingBlock

And if you really need NMS, you can just get the entity's NMS handle after you spawn it with the spigot API

[quaint mantle]

@waxen plinth i want it to be immune to being moved

if im not wrong if you spawn it in normally and set it to nogravity its still affected by explosions and what not

        super(((CraftWorld) loc.getWorld()).getHandle(), loc.getX(), loc.getY(), loc.getZ(), iBlockData);
        WorldServer craftWorld = ((CraftWorld) loc.getWorld()).getHandle();
        this.setPosition(loc.getX(), loc.getY(), loc.getZ());
        craftWorld.addEntity(this);
    }```

ive got this but it just despawns instantly

[waxen plinth]

I don't see why you would need NMS for that at all

[quaint mantle]

why wouldnt i need nms for that

[waxen plinth]

Because you can set the velocity of an entity

[quaint mantle]

is there something in spigot that prevents any sort of movement

[waxen plinth]

You could just literally set its velocity to 0 every tick

[quaint mantle]

yes but if it gets hit by a powerful explosion i dont want it to move at all

i would rather not use a scheduler every tick for it 🙂

[waxen plinth]

How do you expect to do it with nms

[quaint mantle]

just cancel the movement

[waxen plinth]

You could set it to be riding an invincible marker armor stand with noAI and no gravity

[quaint mantle]

yeah

but armour stands have a hitbox which is quite annoying

[waxen plinth]

Marker armor stands do not have a hitbox

[quaint mantle]

marker armor stands?

i dont think ive heard of them before

[waxen plinth]

You can call setMarker(true) on an armor stand

It makes it invisible and have no hitbox

[quaint mantle]

i did not know that was a thing

since when was that added in

[waxen plinth]

1.9 I think?

[quaint mantle]

wow

ok ill give it a shot that sounds good then

[quaint mantle]

are you able to rotate these?

im not sure if im doing it wrong or if they just cant be moved

[stone sinew]

Just clearing something up. Setting an armor stand as a marker still has a hitbox. It's just 1 pixel and doesn't get touched by anything.

[quaint mantle]

really

so can it still be affected by explosions?

[stone sinew]

Shouldn't be able to as it's just a "marker"

But if you show hitboxes using f3+b you can still see its hitbox

[quaint mantle]

ill take a look

more important im trying to rotate it

but it wont work 😦

        this.stand.setRotation(this.stand.getLocation().getPitch() + pitch, this.stand.getLocation().getYaw() + yaw);
    }```

[stone sinew]

Need to teleport

[waxen plinth]

Marker stands do not move

[quaint mantle]

oh really

[waxen plinth]

Why would they

They're meant to be markers

As in, mark this location

It doesn't move, it can't be interacted with

Why would you need to rotate it?

[quaint mantle]

cosmetics!

looks ugly just floating there as an indicator

[waxen plinth]

It's a marker...

It's invisible

Or at least it should be

[sullen marlin]

well ordinary falling blocks definitely can't rotate

[quaint mantle]

md5!

[waxen plinth]

I don't remember, but you can definitely set the stand to be invisible if it's not invisible already

[sullen marlin]

armor stands can on the other hand, so it seems like your initial idea wouldn't work anyway

[quaint mantle]

yeah i learned they cant move just now

[waxen plinth]

I don't get what you're trying to do

[stone sinew]

Why don't you just remove the entity from the explosion damage event?

[waxen plinth]

Make a falling block that can't move... but also moves?

[quaint mantle]

@stone sinew could do, was just trying to see if it could be done easier

[stone sinew]

Easier than a scheduler setting velocity to 0

[quaint mantle]

yea, like just make it so it cant move from external forces but can rotate, but i guess now that ive tried it ive learned that wont work

[quaint mantle]

the blast event? yeah

[waxen plinth]

Yeah falling blocks can't rotate but you can set falling sand as the head item of an armor stand

I'm not sure if armor displays on marker armor stands

But at the very least you can still make them invisible

[quaint mantle]

so dont add the block as a passenger but as a helmet

ohhh TRUE

[waxen plinth]

To my knowledge you can also make minecarts that hold blocks with an offset

[quaint mantle]

i think you can yeah

[stone sinew]

I think so. Check to see if there are any velocity change events to see if you can narrow it down.

[waxen plinth]

I'm not sure the spigot API has support for this though

[sullen marlin]

i believe its gonna be a challenge to find it but i think down the track ill look for it bc honestly the more directions you have the cooler it looks

setDerailedVelocityMod() probs

[sullen marlin]

setDisplayBlockData​(BlockData blockData)
Sets the display block for this minecart.
void
setDisplayBlockOffset​(int offset)
Sets the offset of the display block.

[waxen plinth]

Oh perfect

[quaint mantle]

gonna do that now tbh

[waxen plinth]

That sounds like exactly what you need

[quaint mantle]

hide the minecart and the block will still be visible i assume

my whole idea has been transformed into something better 😅

[waxen plinth]

Not sure if the invisibility potion effect applies to minecarts

But if nothing else works you could always have them be under bedrock with a high offset on the block they're displaying

[quaint mantle]

i didnt know that was how it worked, so you can offset the block thats inside of them? thats pretty interesting

this game is so intricate

[echo basalt]

How can I detect when a player adds a new item to their offhand?

Like from the inventory or something

Preferably getting the old item too

Okay

[quaint mantle]

it seems materialdata is deprecated in many ways

is there a new way to create material data

trying to do
this.cart.setDisplayBlock(type.getData());
(cart is minecart entity and type is Material)

[echo basalt]

basically this

should help

[quaint mantle]

tells me to cast it to materialdata but its deprecated

i guess thats just the way to go

[echo basalt]

might be version dependent

[eternal oxide]

there are two methods. One takes MaterialData, the other take BlockData

[echo basalt]

try using blockdata if it supports

[quaint mantle]

@eternal oxide cant believe i missed that

ayo where can I find this

might need to run buildtools actually

you don't need the craftbukkit dependency. its in Spigot

Oh ty, I thought when they said it was no longer included it wouldn't be. Does that just mean it isn't included if you don't use --build craftbukkit ?

you just build spigot. It has CB and Bukkit

bug 2: when i do click on an allowed slot / result slot then take the result it doesn't remove 1 item from each slot for a second (it's for a second intentionally for testing), then it puts the result in the result slot again

there might be more bugs that i haven't found yet

bug 3: it seems that one recipe does not require clicking on an allowed slot / result slot but the other one does?

@charred wind is points being treated as a string for some reason?

[quaint mantle]

No, ENUMS are compared by ==

[charred wind]

in the json it is a integer

[austere cove]

yo since when can signs be lit

also I can't find the 'lit' value when looking at a sign in game

[chrome beacon]

1.17 iirc

[austere cove]

im in 1.17.1

I mean I figured out how to do it but it still doesn't show up as 'lit'

and I can't /setblock a lit sign

[eternal night]

because it isn't a blockstate

rather NBT

idk what wiki that is

but it should be part of the signs NBT

[austere cove]

hmm yea ig but wiki lists it as block data in the same list w rotation, waterlogged etc

which do show up

[eternal night]

wrong wiki ¯_(ツ)_/¯

it is definitely NBT

Nope

Fix: update pom to use 1.17.1 everywhere, not a mix of 1.17 and 1.17.1

I would wrap the cast around the json_extract, something like CAST(JSON_EXTRACT(stats, '$.points') AS UNSIGNED INTEGER) AS points

Or there might be a json_value() function - I don't know what dB you're using

@eternal oxide remember the problem from yesterday? It was easy: I was just looking at the default config, and NOT at the user made config

[quiet ice]

Okay really stupid question, but how do I make so a class is serialised (via the java serialisation API) as another class. More specifically I am extending java.util.Vector (in the name of "performance") however I want to keep fully compatibility with the old system, which made use of the unaltered java.util.Vector class. I've been thinking that having something like

    private void writeObject(java.io.ObjectOutputStream out) throws IOException {
        out.writeObject(new Vector<>(this));
    }

would work, but apparently it does not and yields

java.lang.ClassCastException: cannot assign instance of java.util.Vector to field de.geolykt.feedbackvectors.collections.IdentityLookupVector.lookupMap of type java.util.Map in instance of de.geolykt.feedbackvectors.collections.IdentityFeedbackVector

even if the class is present (if the class is not present it results in a CNFE). Would I need to extend the ObjectOutputStream here or is there a simpler approach?

[lost matrix]

Take a look at Externalizable
https://docs.oracle.com/javase/7/docs/api/java/io/Externalizable.html

Wait im not sure if i understand your problem.

[quiet ice]

hm, yea, that might work. Surely didn't test that one

[lost matrix]

Probably not what you want. The class identity is always serialized by java. Im not sure if you can serialize the bytes of one object to another.

[quiet ice]

ah.

yep, Externalizable doesn't work. I guess I'll need to do some more hacks and extend the ObjectOutputStream

[lost matrix]

Why do you want to use the java serialisation API anyways?

[lost matrix]

And why cant you just deserialize the byte stream to your own Vector class?

[quiet ice]

well, I need to to be able to be compatible with a protocol that someone wrote that used java serialisation

I really dislike the API, so if I had the choice I wouldn't use it

[lost matrix]

Oof...

[brittle loom]

Hello, I created a method that is supposed to remove all swords until there's only 1 left but I realised it doesn't work. I'm having some trouble finding out what I'm doing wrong, could anyone help me? ``` private void removeSwords(final Inventory inventory) {
for (int i = 0; i < inventory.getSize(); i++) {
final ItemStack item = inventory.getItem(i);

        if (item != null) {
            final boolean isSword = item.getType().name().contains("SWORD");

            if (isSword) {
                final boolean inventoryContainsSingleSword = inventory.contains(item, 1);

                if (!inventoryContainsSingleSword)
                    inventory.remove(item);
            }
        }
    }
}```

[lost matrix]

1. Get the number of swords in the inv
2. Iterate like you do
3. Set index to null and decrement the number until i reaches 1

Your current approach iterates the inventory quite often (inventory.contains).
The one just proposed only exactly twice.

[brittle loom]

Ok thanks a lot for the help, I'll try it out.

[lost matrix]

This should have an even better performance

  public void removeWithPredicateUntilAmountReached(final Inventory inventory, final Predicate<ItemStack> predicate, final int amount) {
    Preconditions.checkArgument(amount > 0);
    final int size = inventory.getSize();
    final Deque<Integer> matchingSlots = new ArrayDeque<>();
    for (int i = 0; i < size; i++) {
      if (predicate.test(inventory.getItem(i))) {
        matchingSlots.add(i);
      }
    }

    while (matchingSlots.size() > amount) {
      inventory.setItem(matchingSlots.poll(), null);
    }
  }

Using scoreboard teams, you can add players to a team and set the nametag visibility to never. Or just set the name to ""

i cant do that on 1.7, i tried but the methods dont exist

[lost matrix]

AAAahaahahah. You must be joking. You mean 1.17, right?

[lyric grove]

xd

[lost matrix]

Right?

[lyric grove]

im not joking lmao

its definitely possible on 1.7, i just dont know how

[lost matrix]

Wow... You know that this version is ancient and you wont get any support for this anywhere.

[lost matrix]

Look into NMS and reverse engineer the code or dig in old forum posts. Usin 1.7 is just seriously masochistic.

That packet didn't exist on 1.7 Gotta find the one that did.

wiki.vg wont help much either

[lyric grove]

should i use nvms? its possible to get armor stands in 1.7 so im sure it will be possible to hide the nametags in that version

[quiet ice]

Finding these ancient versions is hard

[lyric grove]

ok

[quaint mantle]

armor stands are 1.8

[lyric grove]

Its possible to get them into 1.7

[stone sinew]

nope not without mods

[lost matrix]

No. The client doesnt know they even exist and neither does the server.

[lyric grove]

similar to how holo displays patch achieved this it is possible

[lost matrix]

This has nothing to do with armorstands.

[lyric grove]

it does, it spawns a armor stand if the player is 1.8

or horse if player is 1.7

[quaint mantle]

ok but thats still not armor stands in 1.7

[lost matrix]

But a horse is not an armorstand. Its not possible to get armorstands in 1.7

[lyric grove]

yeah just it is possible to spawn them in though

[lost matrix]

No its not

[quaint mantle]

through 1.7, not in 1.7

[lost matrix]

You can always write a packet and send it to a client. Even if you are in 1.2.5 you can technically spawn the wither for a 1.13 client if you just send the right bytes to the client.
That doesnt mean it is actually spawned. Just that the client thinks it is.

can i use hex color code in setPixel instead of MapPalette ?

[cinder comet]

It is option, I just didn't know how to do it

[lost matrix]

Another thing you could take a look at.

how to use byte color ?

[chrome pewter]

so how do i setup nms

??

oh and sorry i forgot please

[quaint mantle]

run buildtools

add the spigot maven repo

[steady rapids]

is it possible to remove this speed limit? when I sprint & jump on a pressure plate (launchpads plugin) I get too fast and i get a teleport bug in game and this warning in the console: https://romano.eats.dog/7mSZ1pAz

[buoyant mica]

do you guys know by chance how to make a good scoreboard for the server

[kind coral]

Hey guys im making a blockparty plugin, tho i would like to set the block as a sort of a grid instead of them being completely random but i really don't have a base and don't know where to start, as anyone got an idea? I got two corners that represent the size of the "terrain" the Y is always the same due to the terrain being only 1 block tall

[waxen plinth]

What is blockparty?

[quaint mantle]

like musical chairs but you have to get on a specific block in time before all the other blocks disappear

[buoyant mica]

yep

like random wool blocks with different colors

its like a stop dance

[kind coral]

yep

the game works great, tho i would like to achieve patterns, them being smaller and smaller everytime

[hasty shard]

If there is someone who writes World Generator for a fee, can they contact me?

[lyric grove]

I think this might be the solution, thanks for the support
npc.getBukkitEntity().setCustomNameVisible(false);

[fleet badger]

Would dripstone growth be BlockSpreadEvent or would it just be BlockGrowEvent? Or BlockFormEvent? or something else?

[chrome pewter]

i install nms and change the api but it still dosent work

[lost matrix]

What pattern do you want? Just a circle or rectangle?

[upbeat sky]

Hey! When compiling I suddenly get this error. Anyone know how to fix?

This is how i registered the command

[lost matrix]

Does your DoomWand implement CommandExecutor?

[upbeat sky]

It does

[lost matrix]

Do you use maven?

[upbeat sky]

I dont, just artifacts

[kindred valley]

hey i made an object named handcluffs and i set its meta when im executing command handcluffs and it gives me default tripwire_hook not the meta one

[halcyon mica]

So how comes my own abstracted interface that implements bukkit's mob fails to compile with this error?

It is not interacting with a vanilla entity at all

[lost matrix]

Make sure spigot has the scope provided

[upbeat sky]

I removed the onCommand and pasted it back in and now it builds.. Weird

[lost matrix]

Just to be clear: You implemented org.bukkit.Entity?

[halcyon mica]

No, org.bukkit.Mob

[kind stirrup]

Hi, I am trying to do command "/god" but something went wrong. Who could help me with that?

[lost matrix]

Set the meta back to the ItemStack.

[halcyon mica]

https://hastebin.com/ukazucisuk.java

[lost matrix]

Just to be in the picture: Do you fork Spigot and are trying to add a new interface for API level usage?

[halcyon mica]

No, this is just a additional library I am creating

I have created a new vanilla entity that I am abstracting through this interface for a actual plugin to interact with

And no, it is not a modded entity, as far as the client is concerned, it is a pillager

[lost matrix]

Ok but your NMS entity does not implement Pathfinder. Right?

[halcyon mica]

No, I have created a proxy spigot entity named CraftPathfinder which extends CraftMob, implements Pathfinder and holds a PathfinderMob handle

[lost matrix]

Ah ok good

[manic bison]

List<String> testlist;

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

[kindred valley]

is there anything wrong?

[halcyon mica]

So why is it complaining about poses

[lost matrix]

For me this looks like some NMS class is trying to implement a Spigot interface. The NMS class has a private getPose() method and the interface
ofc has a public one. This causes a visibility problem.

[halcyon mica]

But the pathfinder interface is in no way related to the nms entity object

[lost matrix]

Do you call your constructor somewhere?

[kindred valley]

no

[lost matrix]

What does your NMS class look like in terms of inheritance?

Including imports

[halcyon mica]

It simply extends mob

[edgy basalt]

Hi !
Does someone know a good tutorial to create my first plugin with visual studio code ? (i've search and i only find tutorial with eclipse)

[lost matrix]

Then the code inside the constructor is never run and the meta is never set.

[edgy basalt]

cause i don't have much space on my computer

i have to install eclipse

visual studio code is on my pc because i need it

for other works

so if i install eclipse it will be VS Code + Eclipse

[hasty prawn]

Eclipse doesn't really require that much disk space, if you're running out already you should get more space.

You're just delaying an inevitable problem

[lost matrix]

I dont even see net.minecraft.world.entity.Mob as a class...

[edgy basalt]

yeah i know but i also prefer to use VS Code cause i use it for many other things

[hasty prawn]

It is

[edgy basalt]

and i know it's possible to do a plugin with it

[hasty prawn]

Mojang Mappings I assume

[edgy basalt]

but i don't find good tutorials

[hasty prawn]

Probably because most people don't use VSCode for Java.

[lost matrix]

Ah i see

[edgy basalt]

Like datapacks in minecraft and Bots in discord

[kindred valley]

thanks i did it and now i know constructors better

[edgy basalt]

Is js = java script ?

[hasty prawn]

Yes

[manic bison]

bump!

and when writing .toString() next to it, all the lore becomes shrunk in 1 line

[hasty prawn]

Aren't Datapacks basically just text files?

[edgy basalt]

no

[hasty prawn]

[lost matrix]

Sure. But rarely any people use vscode for java. You need to search some tutorials for that first then write a bit of java code and after that you might be able
to write a spigot plugin.

[halcyon mica]

I am using mojmap, indeed

Otherwise working with NMS is basicially impossible

[edgy basalt]

they are Json and Mcmeta

[gleaming grove]

is minecraft client based on ticks. What if i create other thread that send packets to client faster then 1/20 sec?

[edgy basalt]

oh

ok

[lost matrix]

Hey sry but i dont see any problem unless there is some nms class implementing a Spigot interface.
How does your CraftEntity look like?

[hasty prawn]

Those are basically just text files, pretty much any IDE can open and write to those 😄

[halcyon mica]

https://hastebin.com/udujaqepom.java

[edgy basalt]

oh

yes

you're right

[lost matrix]

Packets are handled by netty. You can send as many as you want but they get processed in batches.

[hasty prawn]

Vatuu what are you trying to do?

[halcyon mica]

I am creating a abstract pathfinder entity for custom mob ai

Vanilla goals are not suitable for what I need

[gleaming grove]

meh ;/

[hasty prawn]

You can make custom goals by just extending Goal and overriding the methods.

[halcyon mica]

But the client explicitly requested that the entity is compatible with existing spigot wrappers

The very structure of vanilla pathfinding does not fit

[kindred valley]

?paste

[undone axle]

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

[halcyon mica]

I am replacing the entirety of the vanilla entity's path generation and controller

[hasty prawn]

Ah

[lost matrix]

CraftMob already implements Mob.

[halcyon mica]

unless you can tell me how to make a mob clear and jump gaps like a player

[lost matrix]

But that should be fine in my head...

[halcyon mica]

Doesn't matter, multiple implementations are no problem in java

[kindred valley]

https://paste.md-5.net/kaciyogama.coffeescript i have this code i want player to open other players' inventory with that item. And while player clicked entity with that item i set Clickedentity's walk speed but i want to reset clickedentity's speed after closing the inventory how can i do that

[lost matrix]

Do you have a static getPath() method somewhere? (Im guessing at this point)

[halcyon mica]

nope

The only static methods in this context are the spawn method and the verification if it can reach a location

[lost matrix]

There has to be either a static and/or private/protected method which is clashing with the interface method of Entity.
I dont see any other logical explanation.

[lost matrix]

Listen for the InventoryCloseEvent and use the PDC of the player or a hash collection.

[kindred valley]

what is pdc

im beginner

[lost matrix]

PersistentDataContainer

I think you could also just use scoreboard tags.

[kindred valley]

.

[lost matrix]

Ill write you an example of how i would write a simple cuffing system.

[lost matrix]

  private static final String CUFF_TAG = "__CUFFED__";

  public static void setCuffed(final Player player) {
    final Set<String> tags = player.getScoreboardTags();
    tags.add(CUFF_TAG);
  }

  public static boolean isCuffed(final Player player) {
    final Set<String> tags = player.getScoreboardTags();
    return tags.contains(CUFF_TAG);
  }

  public static void unCuff(final Player player) {
    final Set<String> tags = player.getScoreboardTags();
    tags.remove(CUFF_TAG);
  }

  @EventHandler
  public void onMove(final PlayerMoveEvent event) {
    final Location from = event.getFrom();
    final Location to = event.getTo();
    final Player player = event.getPlayer();
    if (!this.isCuffed(player)) {
      return;
    }
    if (from.getX() != to.getX() || from.getY() != to.getY() || from.getZ() != to.getZ()) {
      event.setCancelled(true);
    }
  }

I used a bit more static than i normally would to make it simpler to use.

But generally you would want a way to check if a player is cuffed or not and then react on that somehow.

[kindred valley]

this reaches me sry

[stone sinew]

Make sure to check if the player is being moved or is trying to move in PlayerMoveEvent other wise this will cancel them moving at all.

I think so

[eternal oxide]

not spigot

[stone sinew]

paper

[lost matrix]

No idea what you mean

[stone sinew]

lol

[lost matrix]

How would i check the initiator of this event?

[stone sinew]

IDK might have to do some hacking thing. Was thinking check for the player that is making them move (The one that cuffed them) and add them to a map.

[lost matrix]

Hm. I think listening for incoming move packets of the cuffed one is probably a solid approach.

[stone sinew]

Yeah. Just gotta worry about performance

[candid wave]

Hi Guys, for some reason using nuvotifier on two plugins the vote event is not fired on latest bungee. Is something broken?

you can see the debug log of the vote received but nothing is fired

[lost matrix]

InventoryHolder will never be an instance of Inventory

Idk what you are trying to accomplish with this check.

But remove it

You cant check if a player opens his own inventory

Not possible

Even in huge plugins i rarely have more than 10 eventhandler methods. This is def not the way to go.

[stone sinew]

Could just check PlayerPickupItemEvent

CraftItemEvent

[lost matrix]

Hm. Couldnt you build a PlayerInventoryOpenEvent by using a custom achievement like the vanilla "Taking Inventory"
one and then revoking it afterwards?

[stone sinew]

Events would be your best bet. A scheduler for every player can get pretty laggy.

[lean gull]

plz

[lost matrix]

You can evenly distribute the runnable over N ticks.

[gleaming grove]

@dense goblet, GodCipher, 7smile7 thank you very much for helping me in develop piano
plugin. Here is video of MidiPlayer test https://streamable.com/htvlnz

[hasty prawn]

Now that's cool

[ebon magnet]

Could maybe have a loose schedule, where the schedule simply adds a task to a queue to perform in small portions whenever it has the opportunity.

[stone sinew]

Then you have to worry about timing. So he's doing bingo so what if someone gets bingo first but their task doesn't run till after someone elses.

[ebon magnet]

So instead of saying "At exactly 2:00 PM, not a second earlier or later, you need to immediately drop whatever you're doing and start doing this thing", you'd be saying "Hey, starting at 2:00, would you mind checking this thing whenever it's not too out of your way?"

[ebon magnet]

Well if you're also using Events, they could compliment eachother.

So it's like the equivalent of glancing at somebody's cubicle as you walk by on your way to do something else.

As opposed to actively going in and thoroughly searching every person's cubicle.

[dense goblet]

ayyy nice!

[gleaming grove]

how to make atomic queue?

or thread safe queue

[dense goblet]

if you're trying to implement custom functionality (custom items, custom blocks) then unfortunately you do need to have a lot of event handlers to intercept vanilla behaviour

unless you have a custom core that allows you to register new items and send them as vanilla items to the player

[stone sinew]

InventoryMoveItemEvent?

[compact cape]

Any one good with custom pathfinders? I did my first one, But doesn't seem to work 😂

[lost matrix]

I just need one single listener for custom items which activate by interaction

public class CustomItemManager {

  private static final NamespacedKey INTERACTABLE_KEY = ProjectRevenant.asNameSpaceFor("custom-interactable");

  private final Int2ObjectMap<Consumer<PlayerInteractEvent>> interactableMap = new Int2ObjectOpenHashMap<>();

  public void registerInteraction(final String key, final Consumer<PlayerInteractEvent> eventConsumer) {
    this.interactableMap.put(key.hashCode(), eventConsumer);
  }
  
  protected void handleEvent(final PlayerInteractEvent event) {
    final ItemStack itemStack = event.getItem();
    if (itemStack == null) {
      return;
    }
    final ItemMeta meta = itemStack.getItemMeta();
    if (meta == null) {
      return;
    }
    ...
    Some more logic inclduing PDC stuff

And my Listener is literally just this

[stone sinew]

Is there a clone method for lists?

private List<String> list = new ArrayList<>();
public List<String> getList() {
    List<String> listClone = new ArrayList<>();
    listClone.addAll(list);
    return listClone;
}
```This is what I am currently using.

[lost matrix]

  private final List<String> list = new ArrayList<>();

  public List<String> getList() {
    return new ArrayList<>(this.list);
  }

[stone sinew]

Will that clone it so the initial list won't be affected by the changed list?

[compact cape]

yes new ArrayList<>(your_list) will do the trick

[lost matrix]

Yes. This is the proper way to provide the content of a wrapped collection so that changes are not reflected on the original collection.

[compact cape]

Seems not 😭

[stone sinew]

👍

[stone sinew]

^^^ is for you to xD

[dense goblet]

for blocks I need to intercept any events that change the state of the world (block mined, exploded, changed by entity, burned, moved by piston, etc etc etc).

For items, I have to listen for:
-player interact event
-player interact entity event
-block place event (so you can place custom blocks using corresponding custom items)
-item held event
-player logged in event (to update custom items in their inventory in case their stats changed)

and to stop custom items from being used inappropriately (e.g. using steel as netherite in the upgrade table):
-inventory click
-inventory drag
-inventory move

and for custom recipes and disallowing custom items to be used as substitutes for vanilla items:
-prepare item craft
-furnace burn event
-furnace smelt event

[lost matrix]

Yes sure for protection and block related interactions you need to implement a lot of listeners for different events.
I was talking about implementing multiple listeners for the same event.

[dense goblet]

ahh I see

yeah I don't see the need to listen to the same event more than once unless it's a clearly different purpose

e.g. in my item events class I listen to FurnaceBurnEvent to stop vanilla furnaces burning custom items, while in my world events class I listen to FurnaceBurnEvent to stop custom blocks, which use the furnace as their model, from burning any items.

[halcyon mica]

So it appears the getPose() method in the nms entity and in bukkit's entity conflicts

Which I find weird, because the actual nms entity never touches any bukkit interfaces

[quaint mantle]

is there an event for when the server starts?

[lost matrix]

No. The onEnable() is called when the server starts. If you want something earlier then use the onLoad() method.

[ancient whale]

Hey, I'm trying to get a world with Bukkit.getWorld in the onload method, seem like worlds aren't loaded yet which result in an NPE, is there any other way to handle this without having to put my method in the onEnable ?

[lost matrix]

Depends. What are you trying to do?

[quaint mantle]

How would I go about making a BlockBreakEvent or similar drop a different item than the harvested block? Or a custom item

[lost matrix]

BlockDropItemEvent

[eternal oxide]

you can only remove drops there

[quaint mantle]

Yea

Figured that the hard way

[eternal oxide]

or you can cancel teh break event, set to air and dropItemNaturally

[lost matrix]

Then just get the world from there and drop an item at the broken blocks location.

[eternal oxide]

yep

[quaint mantle]

ok thx

[halcyon mica]

I don't understand this, how is the nms entity attemping to implement the bukkit entity interface

[eternal oxide]

BlockDrop Item is probably best as you leave all the tests to see if it can be broken to other plugins

[ancient whale]

I'm creating a Location from config values

[eternal oxide]

you just deal with the drops

[quaint mantle]

should i cancel it first then set the block to air or otherway round?

[lost matrix]

It usually doesnt. CraftBukkit wraps the NMS entity like you did.

[eternal oxide]

if you only want to change the drops do as 7smile7 said, use BlockDropItemEvent, cancel it and drop the item yourslef

[halcyon mica]

Yet it clearly does somewhere

[lost matrix]

I would use the BlockDropItemEvent instead of BlockBreakEvent

[halcyon mica]

Otherwise this would not be a problem

But I don't understand where

This seems to be something the ide should catch onto

[lost matrix]

Do you get a compile time exception or runtime? Should be compile time and the IDE should catch it.

how do i drop the item?

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#dropItemNaturally(org.bukkit.Location,org.bukkit.inventory.ItemStack)

[lost matrix]

Why you gotta come into spigot and instantly do some weird stuff like that...
net.minecraft.world.entity.Pose Make sure this is actually on your classpath. Do you compile with
the mojang mapped jar?

[halcyon mica]

Yes, I do

[quaint mantle]

i am not sure how to use the dropItemNaturally event?

[halcyon mica]

Because this ain't my first rodeo, and this is the first time I have issues of this magnitude

[lost matrix]

Not an event. Just a method you can call.

[eternal oxide]

It literally takes a location and an ItemStack

[quaint mantle]

ye i meant method

[halcyon mica]

This is far from the worst stuff I have done, that would probably be where I modify the network thread to sent armorstand pose Update packets at 60/s

[lost matrix]

If there is really no nms class implementing any spigot interface then we might have to assume that
the compiler gets confused by the Pose class? Do you have the moj mapped jar and the spigot API as a dependency?

[quaint mantle]

Ok but how do i call it in my event class? e.g.

public void onBlockBreak(BlockDropItemEvent e) {
Block block = event.getBlock();

if (block.getType() == Material.GOLD_BLOCK) {
event.setCancelled(true);
block.setType(Material.AIR)
//call dropItemNaturally method, but how?
...

[lost matrix]

[halcyon mica]

Nope, exclusively spigot

Not spigot-api either

Remapped with mojmap

[eternal oxide]

Don;t cancel the event, just getDrops().clear().

[lost matrix]

Did you install the moj mapped jar into your local maven repo by using BuildTools?

[eternal oxide]

block.getLocation().getWorld().dropItemNaturally(...

[halcyon mica]

Yes

[quaint mantle]

ok thank you

[halcyon mica]

It must be something related to my creation of the entity

Before I went for the spigot-esque abstraction, it worked fine

[lost matrix]

Could you send nms, craftimpl and interface again pls?

[halcyon mica]

One moment

https://hastebin.com/gecosojeje.java

[quaint mantle]

It doesn't seem to work, it didn't drop the item i wanted it to drop. I made sure that the event is registered in my plugin class.

    public void onBlockBreak(BlockDropItemEvent event) {
        Block block = event.getBlock();
        ItemStack test = new ItemStack(Material.APPLE);
        Location blockLocation = block.getLocation();

        if (block.getType() == Material.GOLD_BLOCK) {
            block.getDrops().clear();
            block.setType(Material.AIR);
            block.getLocation().getWorld().dropItemNaturally(blockLocation, test);
        }
    }

[eternal oxide]

Your code will fail as the block is already broken. use getBlockState

[quaint mantle]

kk

[crimson terrace]

use BlockBreakEvent?

[eternal oxide]

no, he;s doing drops

[crimson terrace]

yeah but you can do drops from blockbreakevent

[eternal oxide]

you can but you have to mess with event order etc in case another plugin cancels the event

easier to use the event thats specifically for drops to handle drops

[crimson terrace]

hm, fair point

maybe instead of dropping the item yourself add it to the getDrops?

[quaint mantle]

nah doesnt work that way

you cant add an item to getDrops only remove

[kindred valley]

getScoreboardTags cannot resolve method it says

[eternal oxide]

No you can;t

it says so in the javadocs

not a copy, but not permitted to add

getItems
@NotNull
public List<Item> getItems()
Gets list of the Item drops caused by the block break. This list is mutable - removing an item from it will cause it to not drop. It is not legal however to add new items to the list.

Returns:
    The Item the block caused to drop

[quaint mantle]

Still didnt work. Did i work this correctly into my code?

    public void onBlockBreak(BlockDropItemEvent event) {
        Block block = event.getBlock();
        ItemStack test = new ItemStack(Material.APPLE);
        Location blockLoc = block.getLocation();

        if (block.getState().getType() == Material.GOLD_BLOCK) {
            block.getDrops().clear();
            block.getState().setType(Material.AIR);
            block.getState().getLocation().getWorld().dropItemNaturally(blockLoc, test);
        }
    }

[eternal oxide]

no thast wrong

you can't use getBlock, use getBlockState in the event, not on the block

[quaint mantle]

oh ok

[crimson terrace]

ye

[eternal oxide]

BlockState state = event.getBlockState();

[crimson terrace]

use getItems() to remove the drops

[halcyon mica]

@lost matrix Found anything?

[kindred valley]

dude what is this scoreboard thing can u explain

[lost matrix]

Nope. Makes no sense. Make a new branch and let CraftPathfinder not extend CraftMob but still implement Pathfinder. See if that even compiles.

[quaint mantle]

Thank you finally

[lost matrix]

Just a Set<String> every entity has.

[eternal oxide]

did you fix yoru clear to use event.getItems().clear() ?

[lost matrix]

What version are you on?

[kindred valley]

1.12

[crimson terrace]

if anyones got the time, you know a good tutorial on how to save a hashmap to a file?

[halcyon mica]

I wish you could remove the number every scoreboard line is prefixed as tbh

[eternal oxide]

to yaml? just set it

[crimson terrace]

just config.set(data)? assuming data is the hashmap?

[quaint mantle]

yes

[eternal oxide]

path, map

[lost matrix]

Sure. If key and value type are both properly serializable

[crimson terrace]

ok thats easier than I thought. was going around looking at custom config files

thanks

[lost matrix]

If it doesnt work you can always just iterate through the map and save all pairs one by one

[crimson terrace]

Ive got the key as String for uuid.tostring and the value as Location

[eternal oxide]

you will need to save and reload after setting a Map

[crimson terrace]

ye

[eternal oxide]

If not it will be a Map in memory. It gets converted to a MemorySection upon load

[crimson terrace]

not sure what that means, but Ill figure it out 😄

[stark marlin]

Any idea why my tab suggestion doesn't work? I'm not even receiving the "Test" in the chat while typing.

Why extends BukkitCommand? just implement TabExecutor

[stark marlin]

I need BukkitCommand for the execute() method. Seems that if I try to use TabExecutor instead of TabCompleter it wants to add onCommand() instead
