[round finch]

yeah i did that before

[rare flicker]

what did it give you?

OOOHH

[round finch]

Strings

[rare flicker]

you wanna convert it back

[round finch]

i need the item

[rare flicker]

create a new YAMLConfiguration from each string

and use getItemStack

[wraith apex]

config = YamlConfiguration.loadConfiguration(new File("this/is/where/config/file/is/config.yml"));

[round finch]

my config work is fine

[wraith apex]

aight

[round finch]

just neeed to get content

so i can set it to a inventory

[rare flicker]

gimme a sec

[wraith apex]

idk what the ==: is for

next to org.bukkit.inventory.ItemStack

unless that's using the serialiser?

[rare flicker]

        YamlConfiguration configuration = null;
        List<String> StringList = configuration.getStringList("Enderchest");
        for(String string : StringList) {
            YamlConfiguration stringBlob = YamlConfiguration.loadConfiguration(new CharArrayReader(string.toCharArray()));
            ItemStack it = stringBlob.getItemStack("");
        }

something along theses lines

[hushed pawn]

what is better for scoreboard?

[rare flicker]

multiline string

[wraith apex]

oh

fairs

[rare flicker]

but yeah this should work

[round finch]

maybe getStringList

use String to getItem?

1 sec

[rare flicker]

look up

also found a flaw

theres a StringReader

so

YamlConfiguration configuration = null;
List<String> StringList = configuration.getStringList("Enderchest");
for(String string : StringList) {
    YamlConfiguration stringBlob = YamlConfiguration.loadConfiguration(new StringReader(string));
    ItemStack it = stringBlob.getItemStack("");
}

hi, i have a question... can i use a normal sleep command to make a waiting time in a action of my plugin?

[eternal oxide]

never on the main thread

[ancient plank]

throwback to "why my server crashing? I use Thread.sleep(900000000) to get wait"

[vocal cloud]

Sleeping the main thread so it can take a break

[arctic moth]

what event should i use for when a player obtains and item?

whether that be through crafting, smelting, etc.

InventoryItemPickupEvent doesn't have a getPlayer function

[rare flicker]

use a bukkitrunnable

[river oracle]

You're going to need quite a fee events to manage that logic

[rare flicker]

you can get the viewers and the holders though, which are a humanEntity, that you can cast to player

[arctic moth]

ok

[bronze bison]

quick question about port forwarding, is beacon safe to port forward with? has anyone had experience with beacon? I’ve never used it so I just want to make sure https://www.spigotmc.org/wiki/port-forwarding/

[balmy valve]

Anyone know why Im getting this error?
This is the code for the packet listener:

        protocolManager.addPacketListener(new PacketAdapter(this, ListenerPriority.LOWEST, PacketType.Play.Client.USE_ENTITY) {

            @Override
            public void onPacketSending(PacketEvent event) {
                Player player = event.getPlayer();
                Entity interacted = protocolManager.getEntityFromID(player.getWorld(), event.getPacket().getIntegers().read(0));

                if (spiritEntityManager.getCustomClass(interacted, null) != null) {
                    event.setCancelled(true);
                }
            }

[balmy valve]

Ohh sorry here: https://paste.md-5.net/vilaxitodi.php

Im just le very confused

I just dont get this error

[river oracle]

Why not portforward without an external program

[boreal sparrow]

Where should i put default values, like in the onEnable, and then extend it to another class?

[river oracle]

Wdym by default values

[wary harness]

post some code

[quaint mantle]

i have a class with a deserialization method that gets a location from config. it gets the information on server start.
im getting this error: java.lang.IllegalArgumentException: unknown world

not sure how to fix

[echo granite]

post
your
code

[eternal oxide]

you can;t create a Location for a world that is not yet loaded

[crisp kiln]

i found this thread, https://www.spigotmc.org/threads/custom-sheep-crashing-the-server-on-spawn.512870/ which was exactly what my problem was but i don't exact get what the OP means by "but I renamed the "initPathfinder" and it works!" because isn't the point of naming the function initPathfinder so that the super's initPathfinder get's overrided and instead we set our pathfindergoals in our class? (ping when respond please!)

[quaint mantle]

bro wait

my brain

brb

        LootpoolObj b = new LootpoolObj((String) d.get("name"), (Double) d.get("dropChance"), (Integer) d.get("delay"), (Integer) d.get("radius"));
        HashMap<ItemStack, Double> i = (HashMap<ItemStack, Double>) d.get("drops");
        b.setLocation((Location) d.get("center"));
        b.start();
        for(Map.Entry<ItemStack, Double> e : i.entrySet()) {
            b.addDrop(e.getKey(), e.getValue());
        }
        return b;
    }

    @Override
    public Map<String, Object> serialize() {
        Map<String, Object> s = new HashMap<>();
        s.put("name", name);
        s.put("dropChance", dropChance);
        s.put("delay", delay);
        s.put("center", center);
        s.put("radius", radius);
        s.put("drops", drops);
        return s;
//        return null;
    }```
ive got this running on a sync bukkit task for 0 ticks (which i believe should run once the worlds are loaded)

[boreal sparrow]

As in values that need to be set beforehand, I cant set values in events, because they will be reset every time the event is called

[arctic moth]

oops

[hasty prawn]

Good deal honestly

[arctic moth]

ikr

you have no idea how much grinding it takes for those ingots btw

i made it so you have to smelt the shard thingy for 10 minutes to get one nugget

and you need 9

to get one ingot

i love trolling

[hasty prawn]

10 minutes LOL

[quaint mantle]

i think the issue is that it's loading before the world is loaded

idk how to fix that though

[minor fox]

Does anyone have experience with grafana?

[quaint mantle]

have u registered the event?

[minor garnet]

yes -__

[quaint mantle]

sorry iw as just checking

😄

[opal sluice]

Anyone has a clue about this?

[quaint mantle]

fixed this

[desert frigate]

Would it be possible to make it so hoppers that are under a chest, can't take items from the chest?

[native gale]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/InventoryMoveItemEvent.html

Cancel this event iirc

[desert frigate]

Awesome

Is there a way I can simultaneously change the Material Type of a list of blocks? I am currently trying to replace a pool of water with air by iterating through the list, but it seems like the water replaces itself before all of it is removed. https://paste.md-5.net/hoqafocoha.cs

[eternal oxide]

setType(Air, false)

[strong parcel]

Oh, I will give that a shot. Are there any potential unwanted side effects from canceling the physics on the air block?

[shy rock]

Does it have to be implements listener for item pool to work?

all good

heyy new day

[compact haven]

huh

[carmine nacelle]

if anyone can give input in #1007898521942372364 it would be great

[torn shuttle]

Is there any long-standing api that does pathfinding goals?

[tulip owl]

Why does everyone use Gradle? I’ve always used Maven so I’m just interested 🙂

[eternal night]

caching is interesting especially in regards to NMS

beyond that, having the ability to just code whatever you want in your build script is pretty nice

[tulip owl]

I see, is the syntax much harder?

[tulip owl]

I’ve only found it worse when compiling other peoples stuff because it had to download the gradle version but it could be better on recompile

[wet breach]

maven allows this too

it is just done differently is all

[quiet ice]

So just get 9 ovens

[round finch]

spigot get item name without legacy?

[tulip owl]

And the Minestom docs are written for it, that’s the only time I’ve really used it

[wet breach]

you can make any custom maven plugins that do whatever you really want it to do

[quiet ice]

I myself use Brachyura (specifically my own fork of it) whenever maven does not suffice these days

[tulip owl]

Ah, so is it just easier in gradle?

[wet breach]

I didn't say it was hard to make a maven plugin

it is really simple

[quiet ice]

As simple as using their maven resolver?

If so then "simple" is an exaggeration

[wet breach]

what do you mean using their maven resolver?

[quiet ice]

https://mvnrepository.com/artifact/org.apache.maven.resolver/maven-resolver-api along the other countless artifacts required for it

[quaint mantle]

bro how do i fix this. I literally did what minimessage said to-do. Im also on a Paper build

[wet breach]

<dependencies>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-plugin-api</artifactId>

    </dependency>
</dependencies>

these are the only dependencies you need to make a maven plugin.

[quiet ice]

0 (useable) documentation, 100% enterprise-level

[wet breach]

there is no requirements to have your custom maven plugin hosted on maven central either unless you are intending to share it

but even then, don't need maven central to share it either just makes it easier to do so

[tulip owl]

https://discord.gg/MMfhJ8F or https://discord.gg/papermc but put it on https://paste.gg before asking || that’s a lot of embeds ||

[ivory sleet]

Sure but its less flexible as u have to compile the plugin and what not

[wet breach]

that isn't less flexible. You mean to say it can be a bit inconvenient.

[ivory sleet]

Gradle, just write it out, nothing needed other than that

It is less flexible in my experience

[quiet ice]

I don't percieve that as the main selling point of gradle

[ivory sleet]

It isnt

[wet breach]

You are not limited in what you can or can't do in a maven plugin as its a programming language you are writing in. Java.

From Java, you can invoke literally anything and only limited by your abilities and creativity

[quiet ice]

That may be true but I doubt that you want to use the Unsafe class just to circumvent shoddy API

Writing something in java doesn't necessarily mean you can manipulate other programs to do something you want to

[wet breach]

shouldn't need to use Unsafe and not sure what shoddy API you would be referring to

[wet breach]

But you can

[ivory sleet]

Myes, but gradle becomes easier to bend, or adjust at will at any moment, as you have to rewrite a plugin sometimes in order to change behavior thus requiring recompilation (maven) , gradle has its api, ready to go which with groovy or preferably kotlin dsl becomes way more accessible, flexible and convenient for that part

[wet breach]

Java has a native interface

[quiet ice]

The shoddy API was a blanket statement

[wet breach]

sometimes rewriting a plugin might be necessary, but that is just poor planning when you realize that maven plugins can be used in multiple projects

[ivory sleet]

So?

It doesnt deduct the fact that gradle is way more accessible to arbitrary and powerfully impactful configurations

[tulip owl]

What do you think it is

[wet breach]

not sure what you mean more accessible. Java isn't limiting anything

[quiet ice]

Very easy deployment

[ivory sleet]

Yea but you need to learn the mojo api, and you need to in principle have a good ide to compile your mojo in etc, with gradle its pretty much just write and it works assuming you didnt write anything semantically erroneous

[rapid aspen]

i want help in this code i know some things are wrong thats because i need help
Code: https://paste.md-5.net/huhoquqope.java

[quiet ice]

Also the api vs implementation/providedApi vs provided scopes are another neat main selling point (though that falls under deployment again)

[alpine urchin]

mfw using kotlin

[wet breach]

true, but keep in mind we are indeed talking about two very different methods to accomplish the same thing. One uses plugins the other uses scripts. Technically you can use scripts in Maven too, just need to invoke the appropriate thing is all.

[quiet ice]

what do you want us to do? Perform code review?

[eternal night]

maven allows arbitrary code executing as part of the build script ?

did I miss a maven update

[ivory sleet]

The entire step of having to write a maven plugin as an extra, additional go makes it less accessible and somewhat inflexible, but yeah it would be possible to add scripting to maven in which I guess the difference would be even less significant (theoretically at least)

[quiet ice]

If so public static HashMap<Player, Player> tpa = new HashMap<>(); is an immediate red flag as what do you want to do if a player disconnects?

[wet breach]

it has always allowed this o.O

[eternal night]

wat ?

[glossy lily]

how does someone import a world from singleplayer into a world that can be copied via spigot

[eternal night]

what arbitrary code can you define in your pom.xml

[rapid aspen]

yes just view the code and tell me whats wrong please 🙂

[quiet ice]

plugins

[wet breach]

custom maven plugin

[eternal night]

LOL

[quiet ice]

You can even define custom maven plugin repos

[inland axle]

what should I be using instead of AsyncPlayerChatPreviewEvent?

[quiet ice]

that event is already deprecated?

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[quiet ice]

Ah no, it's just draft API

[ivory sleet]

Its draft api iirc

Yeah

[inland axle]

org.bukkit.event.player.AsyncPlayerChatPreviewEvent is deprecated

[eternal night]

might just be my opinion then but a custom maven plugin that has to be compiled and published in order to work cross devices is so far off from the arbitrary code definitions you can do in gradle it is laughable to compare the two

[quiet ice]

Why the hell is draft API in production

[glossy lily]

_ _

[ivory sleet]

One of the deprecation moments, but not for removal

[eternal night]

to collect feedback ?

[river oracle]

Its because it's draft

[glossy lily]

importing a singleplayer world and then trying to call GetWorld on the name of said world just returns null

[wet breach]

it doesn't need to be published. Just needs to be somewhere accessible. And yes you need to compile the plugins, but you are not limited in what you can or can't do in a maven plugin either.

[inland axle]

is it ok to use?

[eternal night]

you cannot include your maven plugin in the repo directly can you ?

[quiet ice]

We are waiting years for the material rewrite which has been drafted but not put in production yet this draft API goes to prod instantaneously? The spigot team is built out of a bunch of clowns huh

[eternal night]

like gradles build-src

[wet breach]

yes you can

[ivory sleet]

Might change arbitrarily and significantly, but yeah its fine to use

[eternal night]

ah so you code up an entire plugin

and then compile that as part of your pipeline ?

[river oracle]

Probably because it's a breaking change but dumb to withhold still

[glossy lily]

jhfdgajihgfsduihjsdgfuihjsdgfuihjgfsd

[eternal night]

adding draft API for a single event or smaller system is a lot easier than something as massive as the material enum to registry change

[wet breach]

you could if you wanted to, but typically you would have your plugin compiled before hand. However, as far as where you can put it to be accessible, literally anywhere as long as you are able to tell maven where it is at, or you could just manually include it. That is download it and toss it into your maven repo

[eternal night]

I mean, if I have to download a custom compiled maven plugin from some github repo for a project to compile

that is kinda the end of it

[wet breach]

oh so you don't use specialsource?

[eternal night]

having it as part of the project to auto compile or publish it to a maven repo seems to be the only usable options omi

[wet breach]

because that is a custom maven plugin

[eternal night]

which is published to a maven repo ?

[tulip owl]

Paper 😉

[eternal night]

also no lol I do not use special source

[wet breach]

but you do with buildtools

[eternal night]

but I don#t use build tools

tho that is all besides the point tbh

[wet breach]

Anyways point being, yes specialsource has a maven repo, and most custom plugins for maven typically have their own maven repo or are on maven central and that is if you want to share it

[quiet ice]

It is easy to use custom repos for maven plugins

    <pluginRepositories>
        <pluginRepository>
            <id>apache-snapshots</id>
            <url>https://repository.apache.org/content/repositories/snapshots/</url>
        </pluginRepository>
    </pluginRepositories>

[wet breach]

if your plugin isn't intended for everyone else, then it doesn't really matter

[eternal night]

Yea, that is the point I am on

if I just wanna do a small piece of custom code logic in my build pipeline

maven sucks hard compared to gradle

which, that is usually the amount of custom logic you need

everything beyond that is a proper plugin which, both maven and gradle, keep those published in proper maven repos

[wet breach]

or you know just make the maven plugin invoke a console of your choosing and using whatever scripting language you want. Wouldn't surprise me if there is a maven plugin on central that does this already

[eternal night]

that sounds like the hackiest solution possible

[wet breach]

Buildtools does it just fine

most just don't realize it

[quiet ice]

so that is why BT is so unstable?

[wet breach]

in what way is it unstable?

[quiet ice]

People (as in complete strangers) over at #spigot ask for help concerning BT not working all the time

[eternal night]

I mean, idk if I'd personally show off build tools as "look up easy custom code is in maven"

[wet breach]

only because the majority do things that are clearly stated to not do

and then the other small percentage is because of the git library that is the only decent one to use occasionally encounters problems

and then the rest is because their internet sucks

[eternal night]

Welp /shrug, if you wanna actually argue that custom logic in build scripts is as easy in maven as in gradle, I don't think a discussion on this is worth much

idk why build tools still exists, paperclip is just

like better in every way ?

[wet breach]

it isn't. BuildTools is to maven as paperclip is to gradle

[eternal night]

neither of them have anything to do with build tools

[wet breach]

You missed the analogy then

[quiet ice]

I mean it probably is concerning that gradle uses a more or less custom programming language for scripting

[eternal night]

I might have, unless your point was "build tools is outdated bloated and slow like maven whereas paperclip is faster, more convenient like gradle"

[wet breach]

paperclip does what buildtools does, just differently. You could view it as being better but it does have drawbacks

one of the drawbacks is making it more difficult to code against

[eternal night]

Have you compared the two setups for NMS ? xD

[quiet ice]

paperclip and bt were more or less written for two different purposes

[wet breach]

not sure how buildtools is bloated

[eternal night]

Well bloated might be wrong term

does useless stuff might be better

[wet breach]

what useless stuff does it do?

everything it does is required o.O

[eternal night]

patching and building the entire server is not needed

as seen in paperclip

which like, that is the nr 1 reason people use build tools

there is a reason pages like getbukit exist

[wet breach]

it is needed. To build against paper server you need to run paperclip

otherwise you won't have the source including patches

[eternal night]

no you just install a gradle plugin 😛

[wet breach]

the difference is that buildtools just goes ahead and does it in the beginning

paperclip just does it later on

[wet breach]

right because everyone uses gradle

[eternal night]

build tools doing so ahead is a pretty not clever decision

[wet breach]

it doesn't need to be clever

it is simple and easy

that is the intended goal

[dim bronze]

they should do 😏

[eternal night]

Maybe you are not around often enough for the people that think it isn't easy enough and end up on illegal pages like getbukit

[quiet ice]

no, there are better alternatives

at least for a sizeable portion of projects

[eternal night]

tbf, I do have my fair share of maven project xD

[wet breach]

I have yet to encounter a reason to use gradle

[quiet ice]

And for some things gradle is unusuable

[eternal night]

still work well, at least you don't have to update maven every other week lol

[wet breach]

until I encounter that reason, I stick with maven and it hasn't let me down yet

[quiet ice]

Want to deploy your artifact to a maven repo using ftp? Not possible. Using ssh? Nope

[dim bronze]

That joke seems to have caused a ruckus. whoops

[wet breach]

both are those are possible and I have done both

[quiet ice]

Not anymore

[wet breach]

you need to use the wagon plugin

[iron glade]

Guys, might be a dumb af question, but in onCommand I return true by default, would I return true after specific parts too to exit the code?

[dim bronze]

yes to tell spigot the command has been handled

[quiet ice]

Nah, that was removed in a recent gradle release from what I have heard

[wet breach]

I typically like to return false at the end, and return true in the various code bits

[dim bronze]

most plugins aren't managed by gradle?

[wet breach]

oh you were talking about gradle. I was talking about maven

[quiet ice]

Yeah, in maven it is quite easy

[iron glade]

Alright thanks guys, was something I haven't really thought about yet

[quiet ice]

return false if you want to display the "command not found" message

Return true if not

[iron glade]

yeah I don't want that message to pop up that's why I always return true

[quiet ice]

That litterally is the only purpose of the boolean

[dim bronze]

then how does the maven publish plugin do it? https?

[wet breach]

then why bother asking?

[quiet ice]

Though ideally you wouldn't want to ALWAYS return true

[quiet ice]

correct.

[wet breach]

it depends on your configuration

[quiet ice]

https'post or something like that

[round finch]

i'm saving Item names but they're wrong!

how to fix legacy?

[wet breach]

it can use https, ftp, ftps, ssh

[iron glade]

Cause I literally have only one return true in the whole onCommand, was wondering whether I should add more to exit code early

[wet breach]

exit code early if you don't need it to continue further

otherwise you are just wasting resources on unnecessary checks

[iron glade]

yeah that's what I was worried about

[quiet ice]

Again Gradle's maven publish plugin cannot do ftp even if you are hacky and try to insert your own wagon

[wet breach]

that is just weird for gradle not being about to do that

lol

even more of a reason for me to stick with maven 😛

[dim bronze]

I mean seeing as the script files for grade are just groovy/kotlin you could always handle it manually

[eternal night]

pretty sure I have seen plugins for that too, but eek

[dim bronze]

I just feel like gradle is a lot more obvious what it's doing

[eternal night]

Welp does not matter

[vocal cloud]

Gradle is great cause you can do anything with it really

[eternal night]

in the end, personal subjective decision

[dim bronze]

of course

because it's the standard for kotlin I just got used to it and never looked back

[wet breach]

you can do anything with both

as we just explained above

both do it differently

[round finch]

fixed - api-version: 1.18

[dim bronze]

but you can't just write your logic in xml, you'd have to write a separate maven plugin to do what you want and use that (afaik)

[wet breach]

you don't necessarily need separate maven plugins, that is just if you decide to have separate ones. Also, most of the time a maven plugin already exists for what you are wanting, just have to do a bit of searching

maven can also invoke ant as well, which is a build script language

and there is already a maven plugin for ant

[eternal night]

maven can also invoke bash, which is also a language so

checkmate

[dim bronze]

what if windows

[wet breach]

yep it definitely can

[wet breach]

can invoke git-bash

[eternal night]

the straight forward way

[dim bronze]

what if no git-bash / cygwin 🙃

[eternal night]

just write windows compatible bash

[wet breach]

then they are not a developer then and shouldn't be messing with maven anyways

[dim bronze]

okat now I'm trolling

[eternal night]

LOL

[dim bronze]

I'll be quiet

[eternal night]

literally trolling

[strong parcel]

Thanks! That works for removing the water in the specified blocks. However, when the water gets placed, even though I use .setType(Material.Water, false) , the water flows normally. The water that flows out of the zone doesn't get removed. I have been trying to cancel the BlockFromToEvent for blocks inside the flood area, but I haven't been able to figure out how to get the list of blocks from the command to the event handler.

[obsidian drift]

In plugin.yml, if you depend on a plugin, will this plugin be disabled before the dependency?

[eternal oxide]

if you want to affect the flowing water you have to enable physics

[strong parcel]

I am trying to prevent the water from flowing.

[eternal oxide]

or you search for connected water, not just source blocks

[strong parcel]

I am worried that if I search for connected water, it could lead to the plugin trying to delete an ocean or something.

So you're saying that if I want to stop the water from flowing, I have to enable physics?

[eternal oxide]

No, if you want to affect water which is already flowing, you have to allow physics when you remove its source block

to prevent water from beginning to flow, you replace/place it with no physics

[strong parcel]

Okay, I am trying to stop it from beginning.

[eternal oxide]

then do everything with no physics

place with no physics = no flowing

[strong parcel]

I tried to do it like this https://paste.md-5.net/ebohasotof.cs

The water on top of the trees does not flow, but the water that spawns on the ground does flow.

[eternal oxide]

I've never had any issue spawning static water anywhere

[strong parcel]

I will link a video

https://youtu.be/R9I2mWicK4U

[eternal oxide]

odd

[strong parcel]

Should I send all my code?

[eternal oxide]

there is an event for water flowing but I can;t remember the name of it

I don;t think its teh spread event

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockFromToEvent.html

listen for any of your blocks triggering that event

[wet breach]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/block/BlockPhysicsEvent.html

[eternal oxide]

nah not physics

FromTo is pretty much for water/lava spreading

[round finch]

oh he mean state

?

[strong parcel]

I have been trying to cancel that event for blocks in the flood zone, but I am having an issue getting the list of blocks to the event handler.

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

[eternal oxide]

you add them to a List so just DI

What is DI?

[eternal oxide]

?di

[undone axle]

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

[eternal oxide]

as its all in one class you don;t need DI

[strong parcel]

Okay

[eternal oxide]

all you need do in the event is java if (block_list.contains(event.getBlock())) event.setCancelled(true);

[strong parcel]

Do you think there is an issue with the current if statement I have there?

I don't think the block list is getting into the event code block because "Water flow cancelled" never fires.

[eternal oxide]

does water flow detected?

[strong parcel]

Yes

[eternal oxide]

then your blocklist is empty

as yoru sysout for cancelled is not included in the if condition so it shoudl print for every block

[strong parcel]

I don’t know how to get the full blocklist out of the scope of the command and into the event

[eternal oxide]

its already a field

so long as that event is exactly as it shows in teh paste

do you register it as a CommandExecutor and a Listener?

[severe turret]

first of all

he wants to do something with blocks in the flood zone

so you want a map ig

[eternal oxide]

no

teh List is just fine

[severe turret]

no?

[strong parcel]

The class implements CommandExecutor and Listener, and it is registered as an event and a command in main

[eternal oxide]

ok

[crisp forum]

I'm trying to send PacketPlayInBlockPlace but I don't know what is it's fields (using Protocollib) where can I find it?

[severe turret]

You want to use separate classes for different functions

a CommandExecutor should only hold the command

then you get a Map of Blocks and their Location

[eternal oxide]

yes, but he shoudl get it workgin first. Before he goes worryign about single responsibility

[severe turret]

and you check if a block and it's location is in that flood zone

and then cancel the event

[eternal oxide]

thats not what he is trying to do. He's simply spawning static water and tryign to prevent the blocks from flowing

spawning without physics is correct, but I believe he is triggering a physics update when the grass breaks

as such he needs to prevent any of the blocks he placed from spreading

His List is just fine as a Block is a single instance, it simply points to a Location.

all he has to do is ask if teh FromTo block is in his list

@strong parcel try using the line of code I showed you in the event

[severe turret]

I really recommend he uses single responsibility, adheres to coding style and camelCase

would probably make it easier for himself to diagnose the issue

[eternal oxide]

Working and ugly code is better than broken but pretty

[severe turret]

the problem is when a bug happens

try to find it in the ugly code

[eternal oxide]

His code design has nothing to do with his issue

He's actually making it simpler to diagnose with it all in one class

[severe turret]

lol

[eternal oxide]

Yep I looked at the video again, the physics event is being triggered when the grass breaks next to the water which is higher than it.

[carmine nacelle]

alright guys I got a dumb question again like usual

I need to get all field names of the beehive block I punch

[eternal oxide]

We got lots of dumb answers 🙂

[carmine nacelle]

                    CraftBeehive craftBeehive = (CraftBeehive) event.getBlock().getState();
                    Class hiveClass = craftBeehive.getClass();

                    for(Field f : hiveClass.getDeclaredFields()) {
                        System.out.println(f.getType() + " " + f.getType().getCanonicalName() + " " + f.getName());
                    }

this outputs nothing

Now if I output the class name of the Beehive block it just returns CraftBlock, not CraftBeehive

[eternal oxide]

I don't belive getDeclaredFields will get private fields

[carmine nacelle]

but

im tryna do stuff with reflection

[eternal oxide]

If i remember there is a different method to get private ones

[wet breach]

this is most likely what is causing a physics update

anytime something gets modified or triggered, a physics update is triggered for the surrounding blocks/chunk

[carmine nacelle]

Hmmmmm….

[severe turret]

yo what api is that even

I'm looking at spigot javadocs and I can't find any of the methods

[eternal oxide]

Nope I was wroing https://www.baeldung.com/java-reflection-class-fields

[carmine nacelle]

So I’m just doing it wrong or

[severe turret]

oh it's reflection

yeah f that

gl

[eternal oxide]

You need the correct class to start

You will not read fields in the super class

only those in teh class you look at

[carmine nacelle]

I’ve tried Beehive and CraftBeehive both

Both return nothing for declared fields

[eternal oxide]

one sec

let me pull up the class

?stash

[undone axle]

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

[carmine nacelle]

Aight

[eternal oxide]

Correct, CraftBeehive has no fields

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/block/CraftBeehive.java

so class.getSuperclass().getDeclaredFields()

[carmine nacelle]

So use that?

[eternal oxide]

give it a try

[carmine nacelle]

outputs this

[19:43:43] [Server thread/INFO]: class net.minecraft.world.level.block.entity.TileEntity net.minecraft.world.level.block.entity.TileEntity tileEntity
[19:43:43] [Server thread/INFO]: class net.minecraft.world.level.block.entity.TileEntity net.minecraft.world.level.block.entity.TileEntity snapshot

[eternal oxide]

what specific field are you after?

[carmine nacelle]

I need to set the entitycount

[iron glade]

Is intelliJ stupid or am I? It says this method is always inverted

    public boolean hasControlCache(Player p) {

        for (ControlCache c : controlCacheStorage) {

            if(c.getUuid().equals(p.getUniqueId())) {
                return true;
            }

        }
        return false;

    }```

[rare flicker]

is there a way to do something like #PrepareAnvilEvent but for grindstones?

[eternal oxide]

[shadow zinc]

I'm looking for either a sorta convenient way to open a book to collect user data or an api that does it for me

[eternal oxide]

its in the snapshot<Beehive>

[carmine nacelle]

how can you see that?

this search thing on the spigot hub sucks

[eternal oxide]

look at teh CraftBehive link I posted

look at teh method isFull()

it looks at teh snapshot

now open the second link I sent

CraftBlockEntityState.java

its has a field private final T snapshot;

[carmine nacelle]

ok I see that part

so then would I need to keep using CraftBeehive?

or TileEntityBeehive

[eternal oxide]

well you need the snapshot field

[quaint mantle]

why isn't this working? Im trying to do api.doStuff() but it isn't working

[dusk flicker]

does api exist

[quaint mantle]

public class API {

    public static void doStuff() {
        Bukkit.getLogger().log(Level.INFO, "ew");
    }

}```

[dusk flicker]

does doStuff exist

[eternal oxide]

which is a TileEntityBeehive

[quaint mantle]

yes

[carmine nacelle]

which would be TileEntity

    public CraftBlockEntityState(World world, T tileEntity) {
        super(world, tileEntity.getBlockPos(), tileEntity.getBlockState());

        this.tileEntity = tileEntity;

        // copy tile entity data:
        this.snapshot = this.createSnapshot(tileEntity);
        this.load(snapshot);
    }

yeah

[eternal oxide]

TileEntityBeehive

[dusk flicker]

'api'

[carmine nacelle]

which would be the blockstate

[dusk flicker]

its static

[shadow zinc]

bro he jerking off java

[carmine nacelle]

TileEntityBeehive cannot be cast to CraftBeehive @eternal oxide

[eternal oxide]

no

its not the same thing

teh snapshot field IS a TileEntityBeehive

[carmine nacelle]

but I need to get that somehow

[eternal oxide]

You should be able to cast CraftBeehive to CraftBlockEntityState

then you can getDeclaredFields()

[severe turret]

always inverted means anytime you call that method in your codebase you use it inverted

it's just a warning

[carmine nacelle]

@eternal oxide

 Beehive hive = (Beehive) event.getBlock().getState();
                    CraftBeehive craftBeehive = (CraftBeehive) hive;
                    TileEntityBeehive tileEntityBeehive = craftBeehive

[severe turret]

so every time you call it you use it with !

that's about it

[sterile token]

I have disabled that type of warnings because they are really shity

[iron glade]

Ahh I understand

[carmine nacelle]

I only see #getSnapshotNBT

[shadow zinc]

Any suggestions? I have already done a brief google search

[severe turret]

so you'd want to recreate the method to check if a player doesn't have it

instead of have it

since you're always using it like that

[eternal oxide]

Sorry CraftBlockEntityState

TileEntityBeehive is NMS

[carmine nacelle]

so

                    Beehive hive = (Beehive) event.getBlock().getState();
                    CraftBlockEntityState entityState = (CraftBlockEntityState) hive;

                    for(Field f : entityState.getClass().getDeclaredFields()) {
                        System.out.println(f.getType() + " " + f.getType().getCanonicalName() + " " + f.getName());
                    }
```?

nothing still

[eternal oxide]

no clue then, I don;t have an IDE open

[carmine nacelle]

shit

[eternal oxide]

thats definitely the class you need as thats where the snapshot field is

[shadow zinc]

no ide(a)?

[eternal oxide]

Why are you tryign to access a field via reflection again?

[carmine nacelle]

cause there isnt a set method exposed

there is a hive#getEntityCount but no hive#setEntityCount

[shadow zinc]

Whats that theme and how do I get it?

[carmine nacelle]

dracula

[eternal oxide]

yeah you won;t be able to set teh count no matter what, They are actual entities being stored

[carmine nacelle]

well its an int...

[shadow zinc]

damn I didn't know it was so hot

[carmine nacelle]

was told id have to use reflection

[eternal oxide]

yes but it references actual stored entities

[carmine nacelle]

they arent actually stored

[eternal oxide]

no?

[carmine nacelle]

nah

when a bee enters that number increments by 1

so 1 bee, enters 7 times

[wooden cedar]

how to spawn Particle.REDSTONE? it is not working as the other ones

[carmine nacelle]

boom, "7" "bees" "stored"

[eternal oxide]

I thought it stored teh actual entity with its PDC and everything

[carmine nacelle]

not this

every time a bee exits it gets a new uuid

So I have this hive, a bee has entered 3 times

and it says 3 bees belong to it

[eternal oxide]

private final List<TileEntityBeehive.HiveBee> stored = Lists.newArrayList();

thats the NMS

[carmine nacelle]

🤷

[eternal oxide]

    public boolean isFull() {
        return this.stored.size() == 3;
    }```

there is no actual int you are looking for

its an array

that isFull methodf is also bad code

[carmine nacelle]

all I know is.... once the same bee enters 7 times (my max entities that I have set), it doesnt let the bees enter anymore

[severe turret]

dont bees just stop existing the moment they enter

[eternal oxide]

there is a constant in teh class for public static final int MAX_OCCUPANTS = 3;

[severe turret]

I remem someone talking about it

[carmine nacelle]

they respawn

[eternal oxide]

Not looking at teh nms, it actually stores the bee

[carmine nacelle]

@eternal oxide beehive.setMaxEntities

its normally less but I set it to 7 or whatever

so I can have 7 enter

but only once..

cause each time one enters it increases the number

[shadow zinc]

Vivian what icons are you using?

[carmine nacelle]

atom material icons

oh wait

[shadow zinc]

thought so

[carmine nacelle]

i might be dumb

[eternal oxide]

actually I'm wrong, it stores a new set of data, not teh actual bee that entered public void storeBee(NBTTagCompound nbttagcompound, int i, boolean flag) { this.stored.add(new TileEntityBeehive.HiveBee(nbttagcompound, i, flag ? 2400 : 600)); }

[carmine nacelle]

well i am for sure but..

im cancelling them from spawning and spawning my own entity instead

kinda edging the hive

so i guess they stay stored forever..? idk

so maybe instead of cancelling the spawn I need to let them spawn but despawn them right away...?

[eternal oxide]

let them spawn and kill them

[iron glade]

https://www.youtube.com/watch?v=epZVZKLRI6w

Is this a vanilla bug or is there a way I can fix this in my plugin?
(When a player has his inventory opened twice)

[shadow zinc]

ah yes

[round finch]

opening your own inventory?

[shadow zinc]

You could recreate that easily, but idk if there is a buggy way of doing it

Idk if I'm mentally-impaired (apparently the other word violates guidelines) or bad at organizing my code by I can't find a class of mine for the life of me. Is there a way to search for classes in intellij?

[dusk flicker]

Ctrl N

[shadow zinc]

Thank you, thats actually so good

[dusk flicker]

No problem; IntelliJs search system is nice

[carmine nacelle]

yep that was the issue...cancelling the spawn was making it so the stored amount never went down.

[round finch]

you could cancel the bottom inventory? then inventory is open

sorry i'm a little confused
what you making?

[shadow zinc]

In my amazing code, is there a better way to inherit the settings of the parent inventory to the new page? https://github.com/KyTDK/NeoUtils/blob/master/src/main/java/com/neomechanical/neoutils/inventory/managers/data/InventoryGUI.java

Like 68 specifically

                InventoryGUI newPage = InventoryUtil.createInventoryGUI(null, getSize(), title);
                if (pagesInheritParentSettings) {
                    newPage.setPagesInheritParentSettings(true);
                    if (openOnClose != null) {
                        newPage.setOpenOnClose(openOnClose);
                    }
                    if (unregisterOnClose) {
                        newPage.setUnregisterOnClose(true);
                    }
                }```

It's not bad, I just want to make sure that I'm not dishonoring myself.

[carmine nacelle]

actually nope that didnt fix it.

fuck

[shadow zinc]

why can you say fuck but not retort

[arctic moth]

What if I just made it so only one furnace can be turned on in the world at a time?

just to annoy people

[round finch]

pain

[arctic moth]

Don't worry, I have more in plan

[round finch]

Making it so

it says the Location
so players gotta battle for one furance

:)

fun minigame

[arctic moth]

Making a boss that spams one shot moves with a 1/80 chance of dropping something

[arctic moth]

Good idea

[shadow zinc]

Mojang wins in annoying development ideas tbh

get on their level

[round finch]

cough fireflies

[iron glade]

basically it's a /popup command which opens a player's inventory to him, however if you run it on yourself you have your own inventory open twice

[shadow zinc]

bans

[iron glade]

Maybe I should just prevent people from running the command on themselves

[round finch]

that would be easier haha

it doesn't make sense to look at your own player inventory

you can litterally press e

[iron glade]

ikr

[round finch]

🤣

[iron glade]

idk why I didn't include that simple check back then lmao

but funny to see that some people used the command like that and even reported it xD

[arctic moth]

Fine, I'll exploit the reporting system to ban anyone that uses a furnace outside of the specific spot

[round finch]

i thought about p == p?

[shadow zinc]

Now you're getting it

[round finch]

but ye ignoring / skip

sounds a good idea

[round finch]

pfffffff!!!!!

hahaha

must pain full game mode

@arctic moth i gotta each other idea
make stamina

the lower

[lime moat]

How could I make a check determining what the item is? java ItemStack item = player.getInventory().getItemInMainHand();

[arctic moth]

Wdym

[reef lagoon]

Get the type and compare with a material

[arctic moth]

Oh

It's basically hunter though

[lime moat]

Could you explain that a bit more? I was assuming something as simple as this: java if (player.getInventory().getItemInMainHand().equals(Material.AIR)) {

[drowsy helm]

.getType

[lime moat]

if (player.getInventory().getItemInMainHand().getType().equals(Material.AIR)) {``` so this?

[drowsy helm]

Yeah

[lime moat]

Thank you!

[twilit wharf]

I want to create a custom mob, and I need it to attack all hostile mobs. I was thinking using a zombie, but I wasnt sure how to make it not attack the other custom mobs like itself. I would eventually retexture them so that they arent zombies. Any ideas on how I would go about doing this? (Version 1.19.2)

[tulip nimbus]

Use == to compare enums rather than .equals

if (player.getInventory().getItemInMainHand().getType() == Material.AIR) { as == is null safe

[lime moat]

Ah, thank you!

[drowsy helm]

on your target selector there is a last parameter for predicate

just check if the entity is the correct custom one

dont think passing the actual custom entity class in wiould work though

[twilit wharf]

I can check the name of it

although players could potentially name the entities

[drowsy helm]

dont base your system off of names

[dapper saddle]

does if it extends Entity, but I doubt you are setting your custom mobs like that

[drowsy helm]

simple

[deft axle]

tags n such

[drowsy helm]

Custom mobs should always extend entity?

[twilit wharf]

I can check if its uuid is the same as any of the custom entities

[twilit wharf]

that will work

[drowsy helm]

just use an id in nbt

[twilit wharf]

yeah

[lost matrix]

Check if its an instance of your custom entity or tag your entities using theit nbt data

[vocal cloud]

But custom entities don't persist do they?

[twilit wharf]

ok

how can I get a Mob and a Creature from a Entity, can I just simply cast it? (I googled it, couldnt find anything, I might just suck at googling tho)

[drowsy helm]

nope, have to make a system for it

[lost matrix]

Well... you just have to add it to the entity registry. Then they are persisted.

[drowsy helm]

or that

[lost matrix]

You can cast an entity to a Mob if its an instance of a Mob.
Same goes for every cast. Its like this:

• You have an abstraction Car
• In reality, this is a Ford (Which extends Car)
• You can not cast this Car to BMW because its not an instance of BMW. Its an instance of Ford.
• So first, check if its an instance of X. If it is then you can safely cast.

Just casting your Object to something more specific without checking first is bad practice.

[twilit wharf]

yeah, I thought I could just cast it, wasnt sure. I hadnt looked that far into the hierarchy. I do know how casting works, but thanks for the reminder 🙂

[lost matrix]

In Intellij you can just press ctrl + H

[twilit wharf]

[shadow zinc]

[sterile token]

Dont get mad bro i was joking when i reply to you

No because tools can be preferenced differently. If its a fact then you can
quantify and prove it. Which you cant.

[shadow zinc]

Sorry, I didn't know you had a thing for eclipse

[maiden thicket]

eclipse isnt shit its preference 💀

its more user friendly

[lime moat]

So I have this: java if (player.getInventory().getItemInMainHand().getType() == Material.SHULKER_BOX) How can I make all shulker box colors be included in that?

[lost matrix]

I most certainly dont. Doesnt mean i have to vilify it.
You guys most certainly dont have enough experience with
any of those two tools to make any meaningful statement about them.

[shadow zinc]

I was good for me when I was learning, but as you get into more complicated projects you most likely will benefit from using intellij

[sterile token]

USER FRIENDLY? Oh please common on

[maiden thicket]

what

[sterile token]

I can accept others argument but that one one please

[maiden thicket]

u act like its the most biggest piece of shit tool ever

💀

[lost matrix]

There is a Tag for shulkers

[sterile token]

Yeah i really hate it

[maiden thicket]

thats an opinion

[lost matrix]

How much experience do you have with both tools? I mean hands on.

[sterile token]

eclipse 2y and intellij exactly 1

[maiden thicket]

if intellij wasnt made i bet eclipse would be heavily used still 💀💀

[shadow zinc]

oof sorry to hear that

need nms

[lost matrix]

You cant import "Spigot 1.19.2"
Do you mean the artifactId?

[carmine nacelle]

Yes

for maven

well, version

[lost matrix]

Well... the same as for every version. Just with 1.19.2

[sterile token]

?

[shadow zinc]

You need to build it with the remapped version for the version you want to use

[sterile token]

He said he already run it ----

[carmine nacelle]

ah shit

forgot the remapped flag.

[sterile token]

Ah

that why

[carmine nacelle]

thx babe

💋

[sterile token]

Also why remapped flag doesnt work on 1.12?

[lost matrix]

Funny

[sterile token]

Last weeked i look hundred of spigot thread

And i didnt find a solution

[lost matrix]

Because mojang mappings where introduced in 1.17

[sterile token]

OH that why

[lost matrix]

Before that spigot had their own

[sterile token]

Im a idiot

[sterile token]

Spigot have remapped?

Or not

[lost matrix]

I dont understand your question. Spigot has their own mappings.

Which is what you see when you simply use nms in older versions.

Or else everything would be obfuscated.

Uhm... spigot has a transitive vulnerability through commons-codec

[sterile token]

Ok, so what we can do?

Report it to spigot?

[lost matrix]

Well its not too bad. Just blind base32 conversion. So unless the user has a way of writing base32 Strings that get persisted and has information
about the backend implementations, this is pretty negligible.

[iron palm]

is it possible to make a bridge between a spigot plugin & velocity plugin? i cant find any solution

[lost matrix]

Yes there are several ways of achieving this. Do you want a custom solution or is it for a public plugin?

[iron palm]

custom solution its just a private plugin anyways

[lost matrix]

Ok so then i can think about 3 ways right now.

• Plugin messaging channel
• Sockets
• Redis topics

[iron palm]

oh

i dont have redis so i may use sockets or plugin messaging channel could you describe more about them?

[sharp flare]

Is it a good idea of having one connection instance of an sqlite db in a class with static crud methods

[drowsy helm]

yeah, db connections are async anyway

idk about the necessity of them being static though

[sharp flare]

Singleton object of the db class

Oh nvm I'll do dependency injection

Disregard the static above

[carmine nacelle]

Why does this not stop item drops on block break?
event.setDropItems(false);

[lost matrix]

No. You shouldnt only use one connection. Also always close a connection after it has been used.
Use a connection pool like HikariCP which handles connections for you.

[wet breach]

cant connection pool for sqlite

its file based

hikaricp will let you connect using the lib, but it wont use connection pooling for it

[lost matrix]

Every database is file based in the end. Why do you think that you couldnt have a pool for specifically SQLite?

[wet breach]

yes and no. you cant have mulitple file connections opened for the same file. for read purposes it is possible, but in general the OS doesn't like it

the is no server software for sqlite, therefore connection pooling wont work

[compact haven]

he is correct, hikari doesnt support connection pooling with sqlite

[lost matrix]

I mean technically you dont need a connection pool when the db is on the same machine in general because the connection
is established instantly anyways. But i think its good practice to write your code agnostic of the backend.

[wet breach]

you do if you are doing tcp connections even if local

[lost matrix]

So just write it once for SQL and dont worry about the dialect

[wet breach]

however, since java 17 allows linux sockets, if the libs would update to allow that type of connection then you would be correct in that connection pooling won't be necessary

[mental lynx]

Wondering why my mob health is insane in my server.. didn't ever edit it nor do I know how to. Legit didn't change anything and the mobs are 10x as strong as default

[lost matrix]

There is no network overhead when the db is on the same machine...

[wet breach]

there is if you use tcp

not sure where you get the idea that the headers don't exist and all

just because it doesn't leave the machine doesn't mean they are not still created

now it will be quicker for the OS to process though if you are using the loop back device

[lost matrix]

This is just a tiny bit of data. A few more packets that are not even routed through the NIC. Its directly available between applications.

[wet breach]

if you are using the IP assigned to the machine from the network device

then it will go out and hit the network device and then come right back

[lost matrix]

No it wont. All network Layer 3 adresses are locally mapped to the loopback address.

[lost matrix]

difficulty?

[mental lynx]

Normal

[lost matrix]

Probably one of your plugins then

[mental lynx]

It was fine yesterday, implemented some new plugins and it changed

[mental lynx]

DM's, sent a pic of plugins

[lost matrix]

Yeah not gonna look through those. Ill gladly help with development related questions but otherwise you should visit #help-server

[wet breach]

this is not true

[lost matrix]

Actually let me fire up wireshark and double check. But im almost certain that the local routing table has the loopback address as next jump mapped.

[wet breach]

I think you mean to say all layer 3 addresses are all mapped to a single layer 2 address per physical interface

[sturdy frigate]

How do I get a serializable value of a Material? is there an ID of some sort? And how can I reacquire it when loading

[compact haven]

I mean you literally have Enum#name() and Material#valueOf

[lost matrix]

Well... if we are speaking about LAN and you have only one NIC then you will also just have one MAC address. Sure.
But even before that. On layer 3, or more specifically IP, the routing table has your IP address mapped to the loopback
address which means it doesnt even bother the network controller but rather keeps the communication on the bus.

[compact haven]

it's an enum, you serialize it the same way any enum is

[lost matrix]

So enum -> String
And String -> Enum#valueOf(String)
Material has a safer method Material#matchMaterial(String) which also supports namespaced keys and doesnt throw an exception

[compact haven]

sure, but valueOf(name()) is guaranteed to work because they're provided (and final iirc) by the Enum abstraction, so no problem in using those over matchMaterial

it's not like you're having the user give them to you via a config

[wet breach]

it would depend on your OS for the mapping of loopback to the router assigned IP

a typical routing table, does not map the loop back device to router assigned ip or vice versa

since most systems have one physical device, it is quite common to see multiple layer 3 addresses mapped to the same layer 2 address

[compact haven]

taah why u lurking

[lost matrix]

Might be true. But then just use the loopback address when creating a connection 🤷

[wet breach]

it is generally advised to use loopback if the connection does not need to leave the system

as yes it will cut out some but not all overhead

since the headers will still exist and still need to be created as per the protocol requires

[compact haven]

you know that 7smile said there was no network overhead, not that there isn't any protocol overhead

[wet breach]

that is pretty much the same thing

[compact haven]

how

[maiden thicket]

😎

[wet breach]

because the only additional overhead the network does beyond the protocol, is querying for where to send the packets for the next hop. Other then that, the overhead that is typically referred to is mostly coming from the protocol being used for the connection.

[compact haven]

mm I took it more literally, as in the first part

[wet breach]

TCP has overhead in the creation of the headers, the packet body and padding out the packets to be appropriate sizes. And then once the tcp packet is sent, a response is required

if the response isn't received in the configured time for the device

it will send those packets again

if I remember right, the default typically is 3 retries before failing

[compact haven]

well that's because TCP tries to fix a problem, one that doesn't exist for local connections, but I don't think 7smile was arguing that TCP doesn't have overhead

[wet breach]

well even if the connection is local, the protocol still does the same thing

the only difference is that it will be quicker and there shouldn't be failing

[compact haven]

right, because the implementations don't care where the connection is

[wet breach]

if there is you got some major problems XD

[compact haven]

yeah, probably more major than connection optimization xd

this is what my routing table right now looks like

as you can see, the network assigned ip is not at all mapped to loopback

or the loop back mapped to network assigned ip

this is the standard routing table for most people, unless you configured it differently with some scripts or the OS you use just does that for you or something

[lost matrix]

Whats the issue?

[strong parcel]

I am trying to temporarily spawn static water in a radius around the player. I have tried setting applyPhysics to false when setting the air to water and vice versa, but for some reason some of the water still spreads. To stop the water from spreading, I am trying to cancel the BlockFromToEvent for blocks in the flooded area by iterating through the list of blocks in the area and checking if they are equal to the source block in the event. However, the list of blocks appears empty in the event handler, which means the event handler can't check if the source block is in the flooded area.

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

[lost matrix]

The problem here is that you probably create two different instances of your flood.class
Each of those two instance has their own fields. So each has a completely different block_list variable.

[lost matrix]

Before we continue i would suggest that you fix your style issues first.
Class names are always defined in upper camel case. So a manager for player movement would be named PlayerMovementManager
and your flood class should be named Flood

variables and methods are defined in lower camel case. So a method which kills every player with a helmet should be named
killEveryPlayerWithAHelmet() and your block_list should be named blockList

You can right click the variable or class name and then select "Refactor" > "Rename"

[rare flicker]

Is there an alternative to listening for mob spawning events to naturally spawn in custom mobs?
like adding them to minecraft's spawning queue?

[idle loom]

mapping values are not allowed here

[strong parcel]

Okay, I renamed the files that started in lower case, and all of the methods already used camel case. I started with Python, so I use snake_case for variables.

[lost matrix]

Only with a bunch of nms. This needs quite a bit of tinkering.

[rare flicker]

Would reflection be any simpler?

[lost matrix]

Alright. Are you aware what the difference between a class and an instance of a class are?

[lost matrix]

Reflection is just using nms. Its literally the same with the only difference that you dont need nms as a dependency.

[strong parcel]

You can have multiple instances of a class that operate independently of each other, right?

[rare flicker]

That's the point of OOP essentially but yes

let's say i create a custom geyser particle effect

the class is sort of like a blueprint

whereas an instance is a single geyser

[strong parcel]

Cool, I understand.

[rare flicker]

i think i actually prefer that. Guess ill have to peek into the sources or just straight up copy the spawning code

[lost matrix]

I would suggest that you create 3 classes.
A command, a listener and a manager class.
The manager class contains the blockList and each the listener and the command contain the same instance of your manager class.
Thats how you usually do it with everything.

[rare flicker]

^^
point of that is to make sure the manager, listener, and command handler in your code always refer to the same one

[strong parcel]

So the command class would pass the block list to the manager?

[rare flicker]

you can go about it a few ways

• have a reference of what you want be passed in in the constructor
• have the main class have a reference to everyinthing and a static reference to itself so it can be accessed anywhere
• probably a lot of other ways

I think the command should essentially tell the manager to spawn a Flood at the sender's location.

as for the block list, i usually store a public static list of all instances of Flood so i can access all of the affected blocks. Though i'm not sure if that's good practice

it does work though

[strong parcel]

So the flood class would create the block list based on the players location the moment it is initialized?

[rare flicker]

yup

organize your code by "responsability"
"would it make sense for flood to handle its blocks?" if so, then Flood should handle it

[lost matrix]

I mean... i would use a completely different approach

[rare flicker]

I'm all ears to new perspectives

and also one last thing that is sort of unrelated but might help if I understand your case correctly

if the water is purely there for visuals and doesn't need to be actual water, don't use real blocks, use sendBlockUpdate, that way since the water doesn't actually exist it won't be updated, whenver you wanna make it disseapear just call sendBlockUpdate again but with the actual block there

pros :

• will never grief the world, especially useful for things like chests
• no need to cancel any events, the water is fake
• if there is a reload mid-way/crash/bug, the water isnt real so no damage will be done

cons :

• it's not actual water, but only essentially a collective illusion
  edit :
• if the block gets clicked, it resets to the real one

[strong parcel]

What would your approach be?

By the way, you guys have been very helpful. Thank you!

you cas set a custom rgb color and size to it

sample from one of my plugins

[strong parcel]

This is meant to be a pvp power that players can trigger. The water needs to slow people down and interact with Depth Strider and Riptide.

[quaint mantle]

i have the items adder but i think i need LoneLibs

[rare flicker]

the three at the end dictates the size

[rare flicker]

then you need it to be actual water, since riptide gets checked serverside

[lost matrix]

public record Flood(UUID floodId, Set<Location> locations) {

}

public class FloodManager {

  private final Map<UUID, Flood> activeFloods = new HashMap<>();
  private final Set<Location> floodedLocations = new HashSet<>();

  public void addFlood(Flood flood) {
    floodedLocations.addAll(flood.locations());
    activeFloods.put(flood.floodId(), flood);
  }

  public void removeFlood(UUID floodId) {
    Flood flood = activeFloods.get(floodId);
    if(flood != null) {
      floodedLocations.removeAll(flood.locations());
    }
  }

  public boolean isFlooded(Location location) {
    return floodedLocations.contains(location);
  }

}

Ive kept it simpler than i would personally implement it but this is a good start.

[rare flicker]

so you would keep the list in the manager and have it handle that

[lost matrix]

I wouldnt use any lists in the first place. But yes. The FloodManager should be able to handle mutliple floods.

[rare flicker]

i suppose if the list is only ever accessed to know what blocks to check in the listener that would be better

[granite burrow]

yeah it works, but doesn't look good as a sort of flying away particle :/ guess white it is
