[tribal quarry]

same for getItemInOffHand()

[gilded granite]

Oh yeah i used mojangs itemstack

[signal kettle]

ItemStack item = player.getInventory().getItemInMainHand();

[tribal quarry]

watch kody's tutorial, you're probably serializing yaw in a wrong way (Im not sure).

[gilded granite]

Thats why its want working

[signal kettle]

this btw work

[gilded granite]

nice

[signal kettle]

thank you very nice ❤️

[gilded granite]

i just asked chatgpt breh

[tribal quarry]

get nms inventory, and methods should be the same

but why you need that?

for what?

[gilded granite]

to get items in chat

        ItemStack stack = new ItemStack(player.getInventory().getItemInMainHand());
        TextComponent component = new TextComponent();
        component.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_ITEM, ItemContent.from(stack)));```

[tribal quarry]

get the bukkit itemstack

and mirror it as nms itemstack

or just get the handle field (if itemstack is a CraftItemStack)

[gilded granite]

I dont need to use nms itemstack

I just use the bukkit one

[tribal quarry]

So I don't see any issue here, nvm

[gilded granite]

No there is no issues breh

the only issue is that it displays an empty messgae

[slender elbow]

yeah cuz the text component is empty

[signal kettle]

Finally full done of this plugin for my server

[quaint mantle]

thats p cool

[kindred sentinel]

Yooo how did you do 3d.. Armor?

Backpack

[signal kettle]

it’s armor stand that follow you

[kindred sentinel]

I think it's working a bit with lags?

[quaint mantle]

isnt that a lot of packets

and heeavy on playermoveent?

[remote swallow]

item with custom model data?

[kindred sentinel]

Or CIT

[signal kettle]

I mean it’s HMC Cosmetics plugin and its work fine for 100+ players with other heavy plugins like custom blocks, mobs etc without bigger issues so I think it inst that bad

somehow it’s optimised, idk how but if its work well without issues

[signal kettle]

yes it’s pretty much just item with cmd

[gilded granite]

any1 know how do it fix

[signal kettle]

nah I want to make as much feels like moded server without need to use any mods, even optifine, so players ca join, download resource pack and have fun

[hexed kettle]

Does someone know if you can spawn a block display and set a state to interpolate to in the same tick, because when I try that it instantly goes to the 2nd stage without an animation. Delaying setting the state to interpolate to by a Bukkit runnable works tho (kinda dont want to tho). Ty for the answer in advance.

[remote swallow]

use the spawn method with a consumer

[mortal hare]

why intellij so dumb

nvm im dumb it returns previous value 😄

not the current one in the map lol

[hasty prawn]

Yeah usually you're the wrong one if you think IntelliJ is dumb

[mortal hare]

i mean sometimes it really false flags

[hasty prawn]

I've never seen it do it in Java iirc

Rust is a different story however

[mortal hare]

it usually with custom boolean getters

and then it complains that value is not checked

while using object getter after checking the boolean value from the method

and it makes sense because it doesnt know that the boolean getter method is somehow connected to the object

but in that case i would like to be it less agressive

[quaint mantle]

what should I do

[hexed kettle]

dont really understand why it works but nice that it does. Ty
Edit: kinda unreliable tho, sadly. (Works 1/3 cases, randomly)

[mortal hare]

now its really dumb

configurer.getName() returns a nullable

it throws warning for it

but it would get checked anyways in the .addCommandCategory() method above

[remote swallow]

intellij doesnt check othermethods

or think "this method will get called first"

[mortal hare]

intellij is too agressive on warnings sometimes

[compact haven]

bro what

do not say "too agressive on warnings"

it's literally a runtime error vs. a helpful squiggly to remind you something may be wrong

and yeah no IDEA does not recursively check each method for assertions, that's ridiculous

[pseudo hazel]

I mean it can still fail if you call the second method manually

nvm

i read it wrong

but still I agree with dominick

[vital sandal]

Anyone know what is the char code for that ?

[worldly ingot]

For what?

The ping icon? Because that's just a vanilla game sprite

[pseudo hazel]

a char code couldnt have this many colors anyways

[worldly ingot]

Huh? You can colour characters any way you'd like

[pseudo hazel]

well I just mean with the vanilla resource pack/font

[next zinc]

Anyone know why this wouldn't work?

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

I've tried debugging, checking console for errors, etc and can't find any reason why no particles are spawning

The event itself doesn't seem to be called at all

[opal carbon]

so its not prining any of the debug messages to console?

if so

make sure you registered listener

and make sure you did the @EventHandler annotation

[next zinc]

It is registered and had the annotation

omg

it didnt have an annotation

wow

ty for the help

lmao

[plain plaza]

Anyone knows the problem why my ServiceManager is not registering on time or in order?

Main.java (onLoad)

this.api = new API(); // API implements InterfaceAPI
this.getServer().getServicesManager().register(InterfaceAPI.class, this.api, this, ServicePriority.High);

Main // plugin.yml

name: MainPlugin
version: '${project.version}'
main: xyz.apollo30.arcane.Main
api-version: '1.19'```



**SecondMain.java** (onEnable)
```java
ServicesManager servicesManager = plugin.getServer().getServicesManager();
if (servicesManager.isProvidedFor(type)) {
     RegisteredServiceProvider<T> provider = servicesManager.getRegistration(type);
     if (provider == null) return;
     this.service = provider.getProvider();
     plugin.getLogger().info(String.format("Successfully hooked into %s!", name));
} else {
     plugin.getLogger().severe(String.format("Could not hook into %s. This may cause major errors in the plugin.", name));
}```



**SecondMain // plugin.yml**:
```yml
name: SecondPlugin
version: '${project.version}'
main: xyz.apollo30.arcane.SecondMain
api-version: '1.19'
depend:
  - MainPlugin

MainPlugin is a dependency for SecondPlugin and it does load before it but I can't seem to fetch the registered service manager in the second plugin?

Anyone knows what's up?

[slender elbow]

is the second plugin shading the main plugin (api) ?

rather, make sure it isn't

[plain plaza]

doesn't look like it no

[plain plaza]

oh it probably is, one second

Yep that solved it, turns out I forgot to add the scope to provided.

Not sure why it's like that, but yeah thanks for the help.

[warm light]

event get called on this line

then how it going to check from next line if the event is cancelled or not?

[river oracle]

Yeah events are synchronous

So the is cancelled call will be next

[warm light]

but it get called already before cancel.
like if I do any task with the custom event, it wouldn't check if the custom event cancelled or not

[rotund ravine]

Excuse me?

Do you know how the system works?

You call the event

And let listener change the variables etc.

Then you handle the changed information

[sterile axle]

let me introduce you to AsyncPlayerChatEvent

[stray flare]

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

The resetPortalFrames isn't working properly, I mean it doesnt work at all.
My intention was whenever a player used all of his eyes the frames should get a reset or override it by new frame blocks, I tried that but It doesn't really work.

[sterile axle]

As said in #general, add some log lines in your interact event and resetPortalFrames code. However, with that intention you just gave, that's not going to work. You're storing a global count for eyesUsed, meaning every player contributes to that counter whenever the interact event fires. Say you and another person throw one eye each, your listener will have eyesUsed = 2, not eyesUsed = 1 for both of you. You're going to need to use some sort of data structure (like a map or something) to map UUIDs to eyesUsed and check how many eyes each player has used that way.

Anyway the log lines will hopefully shed some light on what's going wrong, as your code should "work" -- but it won't work the way you're currently intending based on your description

[stray flare]

oh alright, I got it now. Thanks I really appreciate it.

[sterile axle]

Sure thing

[river oracle]

Ofc there are exceptions

[stray flare]

My world name was corrupted, that's why it didn't work lol

it was paper_and some numbers idk

and I have changed it by UUIDs that helped, thanks

[kind hatch]

Anyone know why maven throws these warnings and how to fix them?

[tender shard]

because those versions won't be compatible with maven 4 anymore, the warnings should be gone if you update them to the latest versions

you can also set maven.plugin.validation to NONE

[sharp bough]

is it possible to add a value at the end of the chain of tab completion? meaning that it would append to the list of any list of player list in a autocomplete tab, the idea is to add, for example "test" to every plugin trying to autocomplete the playerlist

[kind hatch]

I think you can do that with Player#addCustomChatCompletions()

[sharp bough]

the thing is it would need to have the lowest possible priority, run last, right before sending to the player
to append to the custom lists made by plugins

[kind hatch]

I did that with the maven-shade-plugin, but I can't seem to find any uses of the other plugins in my poms. (Minus special source. I need both versions)

[tender shard]

the compiler plugin and resources plugin are inherited from the "super pom". you can either just set a version yourself without any configs, or disable the validation

though IIRC maven-resources-plugin, latest is 3.3.1 so probably not a big change lol

[kind hatch]

What's a super pom?

[tender shard]

that is the pom that every project inherits automatically

here: https://maven.apache.org/ref/3.0.4/maven-model-builder/super-pom.html

e.g. the one that defines the central repo

[kind hatch]

How would you set the version without any configuration aspects?

[tender shard]

why do you need two specialsource plugins?

[kind hatch]

Multiversion

[tender shard]

<build>
  <plugins>
    <plugin>
      <groupId>...</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.11.0</version>
    </plugin>
  ...

[tender shard]

without modules? 🥲

[kind hatch]

It's multi module, but I'm using the specific version of special source that released with the version of MC in the appropriate module.

[tender shard]

the latest specialsource plugin usually works with all versions

at least for me that always worked. I just always used 1.2.2 lol

but yeah I'd just set the validation to NONE, it complains about many latest builtin plugins too sooo it's kinda pointless

[kind hatch]

I use different versions beacuse I had issues with 1.17. I don't care what anyone says, 1.17 was a scuffed release and the tooling was not on my side.

[kind hatch]

You'd think people would just update the plugins when maven 4 releases.

[tender shard]

maven 4 will break many things anyway

no more system scope 🥳

at least not to files within the project dir

[tender shard]

Automatic parent/dependency versioning
Finally

what should I do?

[teal wagon]

you should shade the library into your plugin

[steel spindle]

how?

[chrome beacon]

Use the shadow jar plugin

https://imperceptiblethoughts.com/shadow/introduction/

[steel spindle]

@teal wagon @chrome beacon You guys are the best! Thank you so much! I was up all day yesterday trying to figure out what was wrong and how to do it right.

[sage patio]

is this:

sorting-types: '[GROUPS:owner,developer,admin,default]'

same as this in yml ?:

sorting-types:
  - GROUPS:owner,developer,admin,default

[chrome beacon]

Swap the ' and [] around

then yes

[sage patio]

like this :?

['GROUPS:owner,developer,admin,default']

[chrome beacon]

Yes

[sage patio]

this is what i'm doing with TAB plugin from my plugin

how?

[small current]

which repository does bStats belong to?

[chrome beacon]

Maven central

[small current]

Im trying to implement AdvancedBan but this happens
https://paste.md-5.net/orafamariq.rb

[chrome beacon]

That's an old version of bstats

Over 2 years old

[small current]

so i should implement the jar?

or implement it myself

[chrome beacon]

You should update

?

[small current]

no im trying to implement a plugin

compileOnly 'com.github.DevLeoko:AdvancedBan:v2.3.0'

i only got this

but bstats error

[sage patio]

leoko plugins are on

maven {
    name = "leoko-dev"
    url = "https://repo.leoko.dev/releases"
}

do you have this in your build.gradle?

[small current]

but in the github page

it said its on jitpack

[sage patio]

i'm using AdvancedGUI api in my plugin, this works fine for me

try this one

[small current]

aight

same error

when i implemented bStats myself it was fixed

[sage patio]

no idea, didn't used bStats over 2 years, all of my plugin are private
but the last time i used bStats it was a class to use in the project

try implementing the class instead of using gradle or whatever

https://bstats.org/getting-started/include-metrics

[livid dove]

Bstats 1.5 aye? Pretty sure in those days it was just a class but nowadays u need ur plugin I'd too

Id

[sweet sonnet]

add dependancy, shade it, make new instance with your plugin id you get from the website

https://paste.md-5.net/tihicexoku.cs
This code does not give any error to the console. What it needs to do is run a method that will save the locations of the blocks that are placed and broken later and delete them. It saves locations and can delete and replace blocks whenever I want. But when I break a block I put myself, it puts it back in its place. How do I prevent this?

[lost matrix]

What do you mean by that?
But when I break a block I put myself, it puts it back in its place

[snow shadow]

Let me explain it this way. I want to reset a specific field. Players can block or break. But if I type a command like /map restart. The area should be restored, that is, the broken blocks must be restored and the laid blocks must be deleted.

If I put a block and break it, when I type /map restart that block comes back. I don't wanna this.

[lost matrix]

Then only track the very first time a block gets altered. This way you will always have the original in your map.

[snow shadow]

Sorry, I didn't fully understand that. Can you explain this a little more?

[lost matrix]

So you want to have an area which can be restored after players are done playing in it, right?
Then start by creating some Map<Location, BlockData> where you can store blocks.
Now if a block gets changed for the first time by events like:

• BlockBreakEvent
• EntityExplodeEvent
• BlockFromToEvent
  etc. -> You store the block in the Map<Location, BlockData>.
  But after a block has changed once (for example if someone breaks a grass block) you dont save the data
  if the block changes again (for example if someone places another block there).

So before adding something to your map, you simply check if this location is already filled with original
block data. If it is then you dont overwrite this data.

[snow shadow]

Oh

Okay

Thank you 7smile7

[smoky oak]

If you use Collection<Object> as a parameter and do manipulations to the objects in that collection, would a list passed into the method retain it's ordering if the list itself is not changed, and iteration happens with a for(Object o: loop?

[lost matrix]

Generally speaking a collection does not change its order if the state of their elements are mutated.
But there are only a few collections which have an order in the first place. Sets for example are by definition unordered.

[smoky oak]

lright

Also relevant though for a completely different reason, does bukkit have any internal methods for vector math? I need to rotate a set of locations that 'point' towards 'north' by yaw and pitch

*around a specific point, not around 0,0,0

[lost matrix]

Yes, you can rotate a vector around any axis

well the axis for the second rotation changes with the first rotation doesnt it? Thats kinda why i asked if bukkit has some internals for that, i do recall java having vectors

[rotund ravine]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/util/Vector.html

[smoky oak]

I'm not sure how to obtain the second rotational axis

[lost matrix]

What are you trying to rotate?

[smoky oak]

a set of particles to align with player vision

the first rotation makes it so the second rotation axis no longer is a unit vector a la two 0 one 1

I dont recall the operation to obtain the correct secondary rotation axis

[lost matrix]

A rotation doesnt change the lenght of a vector...

[smoky oak]

i rotate by pitch and yaw. I can do either by rotating around 0,1,0 or 1,0,0, but the OTHER rotation axis changes if i do the first rotation

i need that second axis

[lost matrix]

What do you mean the other rotation axis changes?

You can rotate around 0,1,0 and then around 1,0,0

[smoky oak]

if you have a single vector, yes

*maybe

but if you want to rotate a bunch of stuff, the projection gets warped if you do that

the second rotation axis is perpendicular to y and the rotated vector

[upper hazel]

intellij became shit when it updated to the latest version what the fuck. Any idea how to enable autosave?

[tall dragon]

autosave?

[upper hazel]

yes

[tall dragon]

intellij always saves almost immediately

[upper hazel]

no

[tall dragon]

idk what u have done then

[upper hazel]

it reacts to events

close, run e t c

[smoky oak]

actually that axis is probably either the dot or cross of the 0,1,0 and the rotated vector lol

nvmind

[upper hazel]

intelji now freezes frequently

[tall dragon]

havent had issues with that just yet

[upper hazel]

you update last version?

[lost matrix]

You are freezing one degree of freedom. You dont have a roll.
I dont see the problem. Otherwise i would have suggested using qaternions or a rotation matrix for this.

[upper hazel]

if yes, then try to copy the name of material and paste and find out

[smoky oak]

ah

i need to rotate around both

to move a image thats projected 'north' to align with the player vision

i said AND not OR

also

pitch and yaw cause roll if you rotate 1,0,0 and 0,1,0 instead of the secondary shifted rotation

[tall dragon]

yea

[tall dragon]

not sure what u mean by that

[lost matrix]

1. Make your map private, and non-static
2. Make the restoreBrokenBlocks() method non-static
3. Modifying a map while iterating over it will cause a ConcurrentModificationException
4. Show the rest of the code

Also: This if clause will cause a ton of trouble. I dont see the logic behind it really...

    public static void restoreBrokenBlocks() {
        for (Map.Entry<Location, BlockData> entry : originalBlockData.entrySet()) {
            Location location = entry.getKey();
            BlockData blockData = entry.getValue();

                originalBlockData.remove(location);
            }
        }
    }

should be just

    public void restoreBrokenBlocks() {
        for (Map.Entry<Location, BlockData> entry : originalBlockData.entrySet()) {
            Location location = entry.getKey();

[lost matrix]

Havent used this in forever.

[lost matrix]

1. Create an instance of BlockRestorer in your JavaPlugin class (only 1 !)
2. Pass this instance through the constructor of every other class which needs this instance

This is called dependency injection.
You should try to write your next plugin without using the static keyword, at all.
It should be rarely used anyways.

[median fern]

So how do I use that Serialization stuff

[snow shadow]

be ashamed

[lost matrix]

A class is just a blueprint which describes functionality. It can do nothing on its own. You cant call anything in it and dont use its variables.
If you want to use it you need to create an instance of this class. This means you 'build' or 'construct' an object using the new keyword.

BlockRestorer someVariable = new BlockRestorer();
BlockRestorer blib = new BlockRestorer();

This code snipped created two instances of your BlockRestorer class.
They each have their own methods, own maps and are completely independent from each other.

[snow shadow]

Actually, I have a little knowledge of these, but when someone says "do instance" to me, I can't understand what to do.

Thank you

Also you are so handsome

😃

[lost matrix]

[cobalt thorn]

I got a question based on an Scp (Scp-294 or the coffee machine), its possible to pull of all the possible material in existence and give them something they do like in the wiki is written “anti-water” and pull it off inside the game or any other real life material as a water bottle and give them effect based on the name

[quaint mantle]

yes if you make it ofc

[snow shadow]

But in order to use it in other classes, shouldn't I make it public static instead of private? Now I deleted the BlockRestorer variables that I created in other classes and nothing changed 😄

[cobalt thorn]

But how using ai only that’s my only idea

[cloud knot]

Guys Is there any plugin that if a player sends a Chat the nearest player will be the only one to read it and so the other players who's far off from the Player who Sends the chat it will not be visible

[quaint mantle]

then do it

[cobalt thorn]

But never worked with ai and java is probably not the best for it

[quaint mantle]

then learn how to work with ai

[echo basalt]

[lost matrix]

You need to pass this instance around. Every class needs to store a variable which contains this instance.
This should be done in their constructors.
For example

public class RestoreListener implements Listener {

  private final BlockRestore restore;

  public RestoreListener(BlockRestore restore) {
    this.restore = restore;
  }

  @EventHandler
  public void onPlace(BlockPlaceEvent event) {
    Block block = event.getBlock();
    Location location = block.getLocation();
    ...
    if(!this.restore.hasOriginalBlockData(location)) {
      this.store.storeOriginalBlockData(location, block.getBlockData());
    }
  }

}

[snow shadow]

I did this class but I have to shyly ask something. What are we doing now? 😄 Initially the ide was not giving an error, and was just tiling a block that didn't need to be tiled. Now IDE 3 is throwing an error and nothing is working.

||Please don't write too long, I feel guilty when you write me long texts||

[lost matrix]

You need to overhaul quite a bit of your plugin if you abused static before and are now switching to proper dependency injection.
You onEnable might need to be updated to something like this:

public class RestorePlugin extends JavaPlugin {

  @Override
  public void onEnable() {
    BlockRestore restore = new BlockRestore();
    BlockRestoreListener listener = new BlockRestoreListener(restore);
    BlockRestoreCommand command = new BlockRestoreCommand(restore);

    Bukkit.getPluginManager().registerEvents(listener, this);
    getCommand("restore").setExecutor(command);
    ...
  }

}

And no worries, we are in this channel to help. If i get bored i can just leave

So remove all the static methods and variables and replace them all with calls on an actual instance of a class.

[lost matrix]

tensorflow is available for java, so why not

[snow shadow]

I guess the errors are not related to that. Errors: Cannot resolve symbol 'blockRestorer' & Cannot resolve method 'restoreBrokenBlocks' in 'EventCommand' & Non-static field 'originalBlockData' cannot be referenced from a static context

[lost matrix]

Those are all errors that indicate that you are still missing quite a few things in your listener and command classes.
Mainly the fields that store your BlockRestore

[snow shadow]

oh okay

give me a second

😭

3 new errors

[lost matrix]

Lets see them

[snow shadow]

I did what you said in classes with errors
There is no change in the old errors, but the new ones are as follows: Variable 'plugin' might not have been initialized & Variable 'restorer' might not have been initialized & Cannot resolve method 'restoreBrokenBlocks' in 'EventCommand'

[lost matrix]

Show the classes pls

[snow shadow]

?paste

okay please check dm

[lost matrix]

    private final RestartMap plugin;

    public EventCommand(RestartMap plugin, BlockRestorer restorer) {
        this.plugin = plugin;
        this.restorer = restorer;
    }

Change what you have to this.

[snow shadow]

Well, is there a solution to other errors?

Cannot resolve method 'restoreBrokenBlocks' in 'EventCommand'
Non-static field 'originalBlockData' cannot be referenced from a static context

[lost matrix]

restoreBrokenBlocks(); -> this.restorer.restoreBrokenBlocks();

[snow shadow]

oh okay

And the second one is from a different class i assume

This will show another problem. I think you can solve that

[echo basalt]

only problem I see is using locations instead of blockvectors or whatev

[snow shadow]

The IDE is not giving any errors now

[cobalt thorn]

Probably goin on keywords like molten etc to understand what item because on the wiki is written that some material can give an error to the machine or if they are not found in a radius in realities or the current world

[snow shadow]

I'm really ashamed to say this, but the situation is still the same. The blocks I break do not come back.

[echo basalt]

[snow shadow]

BlockRestorer: https://paste.md-5.net/esicanohav.cs

    @EventHandler
    public void onBlockBreak(BlockBreakEvent e){

help who has a tutorial or piece of information related to the topic of schematic file regeneration

[round finch]

1 you could use worldedit api or 2 you could make a custom schematic file system

[eternal oxide]

Bukkit already has schematics

[round finch]

besides that there is regions

You just make a grid and templates

[upper hazel]

there is everything related to the regeneration of the schematics?

[echo basalt]

uhh

Just unload and re-paste

It doesn't really "regenerate" them as much as it just nukes everything

[upper hazel]

oh

[echo basalt]

otherwise you have problems with entities and weird blockstates

[upper hazel]

everything is much easier than it seemed lol

does the automine connected with trees also work?

[echo basalt]

no clue what you're on about at this point

[upper hazel]

bruh translate sack

this traslate really sack

and the plugin for the auto mine where the trees appear also regenerate so?

I have made one before

[tender shard]

yaay my PR for the mvdev plugin was merged

[sterile token]

oh merging it such an as**le working. I always broke things merging

[tender shard]

then you're doing it wrong lol

[sterile token]

yeah, any recommendations? i Mean if i dont disturb you of course

[tender shard]

usually merges work 100% automatic unless the file was changed after the PR was opened

[sterile token]

Most of the time when im merging 2 branch togethers, it opens lost of issues related to same files changed

[tender shard]

if they don't, then you'll be shown an editor with a bunch of >>>>>>>>>>>>>>>>>>> lines and you'll manually have to merge it, then remove all those "merge" lines

that's called a merge conflict

[sterile token]

yeah i always have them

[tender shard]

that can only happen if you edit two branches at the same time or if the target branch has been changed after the pull request was opened

[sterile token]

oh right

[tall dragon]

does any1 know if its possible to "speedup" certain tile entities easily? say hoppers for example?

[tender shard]

there's settings for hoppers in bukkit.yml or spigot.yml

[tall dragon]

right there is. but i want to do with specific ones

not all of them globally

[tender shard]

that's not possible, they get ticked when they get ticked. IIRC the server loops over all TileEntities every tick and then if it's a hopper, does the hopper logic if the current tick number is dividable through the hopper speed or sth like that

I mean you could ofc manually loop over them and manually cause them to update

the NMS hopper should have a tick() method that oyu can call

[tall dragon]

pretty sure it just counts down an integer which spigot then sets to whatevers been set in its config after the hopper logic

[tender shard]

yeah but it doesnt do that for each individual hopper

[tall dragon]

thats probably the only way then yea

possibly

[tender shard]

hm looks like cooldownTime is stored per hopper, not globally

so you could try to set it for individual hoppers

it's in TileEntityHopper

[tall dragon]

ah yea i did think so wasnt sure

though after each iteration of its logic, spigot will set it no?

[tender shard]

probably. I have only checked the craftbukkit code, which uses the hardcoded values and the pushitemsTick method seems to be unused

[tall dragon]

didnt you also have a post on using remapped spigot?

[tender shard]

?nms

[undone axle]

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

[tall dragon]

cuz i havent rlly done that before

thanks

[tender shard]

np

I think the actual logic is the static method tryMoveItems in TileEntityHopper

[tall dragon]

yea pretty sure it is

it will check its time stuff every tick and then it calls that

il go and see if i can hammer something feasable out. thanks for the insight

[tender shard]

good luck!

[grim hound]

I just wanted to make a ping check

using keep alives

[echo basalt]

pdc

[tender shard]

Always pdc

Pdc best

[chilly hearth]

how does pdc will help

[tender shard]

You give the entity a pdc tag

[chilly hearth]

you mean i can store a key to that entity and how do i accsess to another class ?

oh

Or if you really care, change your listeners to put your old block data onBreak and onPlace

[dawn flower]

how do i stop the vanilla mining animation in a BlockDamageEvent? i want to replace it with a custom one, do i just cancel the event

[echo basalt]

You really can't

or well

It's weird

Mining fatigue n all

[dawn flower]

i think mining fatigue -1 works but im not sure how ill give it before the actual animation pops up

i want to make custom mining

[tender shard]

https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/

[echo basalt]

you aren't the only one

ideally you give it permanently and rewrite all the block breaking logic

[snow shadow]

I remember doing what he said

[tender shard]

basically you can just create a NamespacedKey in your main class, e.g. "is-my-custom-entity" as public final field. Then when you spawn the entity, you apply this with a random value, e.g. string or byte (or boolean when on 1.20), and when the entity dies, just check if it has that tag

or with a getter ofc

whatever

[dawn flower]

i really dont want to mess with the other blocks breaking logic

ill figure it out ig

ty tho

[clever lantern]

what to add in itemmeta so my listener can later recognize this item and it wont be visible in game

[tender shard]

https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/

[sterile token]

is it okay to update an scoreboard every 5 seconds?

[eternal oxide]

yes

[sterile token]

right, i mean because i dont cause server issues related to executing too many tasks and made it really periodically

[clever lantern]

one more q, what are attribute modifiers and item flags used for?

[tender shard]

attribute modifiers change attributes, like generic armor, movement speed etc.

item flags are self explanatory, e.g. HIDE_ENCHANTMENTS will hide the enchantments, etc

[clever lantern]

ok tysm

Hi! I need some help figuring out why my plugin doesnt detect this PiglinBrute entity.
Error: Caused by: java.lang.NullPointerException: Cannot invoke "com.dumbllama.halalboxcustombosses.mobs.Hellboss.getInstance()" because "this.hellboss" is null

Where I need to detect it:

  private HellBossManager bossManager;
    public Hellboss hellboss;
    PiglinBrute mob = hellboss.getInstance().boss;

    private int timeLeft = 10;

    public BossKilledTask(HellBossManager bossManager){this.bossManager = bossManager;}

I declared it here: (Different class)

  private Hellboss hellboss;

    public Hellboss getInstance() {
        return hellboss;
    }
   public PiglinBrute boss;

     public void Spawnmob(Location loc, HalalBoxCustomBosses plugin){
         boss = (PiglinBrute) new MobSpawn("§c§lHell Boss",500, EntityType.PIGLIN_BRUTE).spawn(loc);
         boss.getPersistentDataContainer().set(hellBoss, PersistentDataType.BOOLEAN,true);
         boss.setAdult();
         boss.getEquipment().setItemInMainHand(weapon);
         boss.setAI(true);

         boss.getAttribute(Attribute.GENERIC_ATTACK_KNOCKBACK).setBaseValue(5);
         boss.getAttribute(Attribute.GENERIC_ATTACK_DAMAGE).setBaseValue(5);

[lost matrix]

Well if you dont write something in your hellboss field then it will contain null...

[upbeat fog]

In a different class I declared the hellboss.

[lost matrix]

That just means your code ran before you set the field from outside.
PS: Never make your fields public.

[upbeat fog]

yeah I dont usally do that xD

I just needed to access the mob

in a different class

[bitter rune]

Just a note you can use ChatGPT for free and it'll literally create codes for you and fix your code, you can also have it completely explain in great detail how the code works. May help some

[lost matrix]

Ok. Still no reason to make it public.

[upbeat fog]

I just realized I created an instance for the class xD

[lost matrix]

It will also spit out an incredible amount of garbage and outdated code because of its ancient dataset.
Not a good tool for spigot at the moment.

[bitter rune]

You can have it use updated code you have to be precise in exactly what you want

[upbeat fog]

So how would you pass the mob to a different class so it won't return null?

[lost matrix]

Its missing context because the dataset is from a few years back and will not have sufficient knowledge about
the latest API state. You can give it as updated code as you want. It wont have enough background knowledge for
quite a few code problems.

[tender shard]

it'll frequently come up with with total shit code though

[lost matrix]

Create a custom mob manager which maps spawned spigot mobs to your custom mob classes.
Something like a

public class CustomMobManager {
  private final Map<Entity, CustomMob> spawnedCustomMobs = new HashMap<>();

  public void handleInteraction(Entity entity, Player player) {
    CustomMob customMob = spawnedCustomMobs.get(entity);
    if(customMob == null) {
      return;
    }
    customMob.interact(player);
  }

  ...

  public void handleDeath(Entity entity) {
    CustomMob customMob = spawnedCustomMobs.remove(entity);
  }
}

Then you create one instance of this manager in your onEnable and pass it
to your listener and command classes.

[upbeat fog]

so even if there's one mob at a time you'd still recommend using this?

[lost matrix]

What if you decide to use this system to spawn little minion mobs for your boss?
You wouldnt want to rewrite your code for that.

[upbeat fog]

Hmm yeah, that's a good point. Does a projectile also counts as entity?

[onyx fjord]

yes

[lost matrix]

But i wouldnt classify it as a custom mob

I would probably create a dedicated custom projectile manager for that 😄

[upbeat fog]

Cool, I'll try this method.

[shell robin]

[true perch]

What method makes an entity glow?
https://www.digminecraft.com/effects/images/glow.png

[tender shard]

I still don't get why a List<?> is not considered to be a List<Object>

[slender elbow]

cuz variance

[tender shard]

variance?

[slender elbow]

covariance and contravariance

my people are calling me

[tender shard]

if I can loop over it like that, then why can't I declare it to be a list<Object>

oh yeah I couldn't add anything to the list

makes sense now

[slender elbow]

because that's the upper bound, but you don't know the exact type the list is holding

[lost matrix]

Just add a glow potion effect?

[tawdry echo]

Effect glowing

[slender elbow]

which is why you can't add elements to the list (except for null :^) ), because you don't know what exactly it's holding, you just know you can get {upper bound type}s out of it

[lost matrix]

i find contravariance to be handled very weirdly in java to be honest...

[near mason]

Entity#setGlowing(boolean)

[true perch]

Got it!

Anyone know how to change the glow color?

[near mason]

is potion effects better usage of api?

[lost matrix]

Glowing potion effect
Glowing entity effect
❌ setGlowing

Thats literally the one way to not make it glow

[near mason]

why

[true perch]

Okay I'll search around for the others

Because it does refers to an entity property and not the glowing effect

i think you should check the javadocs before using reflection

[muted dirge]

i googled it but only found nms one

[lilac dagger]

but stilll you can just wipe away all the dev's work by setting the list to raw

and it'll work

[muted dirge]

omg im dumb

[near mason]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Entity.html

you can do ctrl f and search the method

[muted dirge]

I'm creating a plugin for summoning tiny and huge mobs

[remote swallow]

or just use the brower and search for Entity.setAI

[muted dirge]

found it

[lost matrix]

Mobs cant really be scaled, can they

[near mason]

no they cant

i searched for that a lot back then

but except april fools snapshot

i dont know if spigot api has that

[true perch]

Do you happen to know which EntityEffect will yield my desired result?

[remote swallow]

Glowing probably

[true perch]

Don't see any with glowing

[muted dirge]

why not?

[near mason]

glowing doesnt exist

[muted dirge]

EntityDimensions entityDimensions = (EntityDimensions) dimensionsField.get(nmsEntity);
EntityDimensions scaledDimensions = new EntityDimensions(entityDimensions.width * s, entityDimensions.height * s, entityDimensions.fixed);

[lost matrix]

Because minecraft doesnt support that internally

[muted dirge]

I'm trying to do it

idk

[lost matrix]

Use the potion effect

[near mason]

i still dont get why not just Entity.setGlowing 😐

[lost matrix]

Because tinkering with the color requires teams

[lost matrix]

This will just mess up the hitbox

[muted dirge]

based on nms.screamingsandals.org/1.20.1/net/minecraft/world/entity/Entity.html the obfuscated name is "bh"

is it right?

[remote swallow]

yea

[near mason]

btw

whhen you change the hitbox of entity with nms

does it change in client-side?

[muted dirge]

its just a fun plugin i think no one would care

[near mason]

like can you see the change with f3+b?

[muted dirge]

how?

can you send the method for me?

[near mason]

i dont remember it

hold on im searching it

[muted dirge]

thank you

[true perch]

How do you apply a potion effect to an Entity? I know you can do it to a LivingEntity, however I don't see any methods that allow this for an Entity.

[near mason]

oh there isnt a way

😐

[echo basalt]

Just do an instanceof check

[near mason]

there is this

[true perch]

I'm attempting to make a ground item have specific color glows

[echo basalt]

glow colors are uhh

just scoreboard teams

[near mason]

but you can set the collision box

[echo basalt]

Entity glowing (contrary to what 7smile7 says) is ideally done with Entity#setGlowing, as it sets the field in the entity metadata packet instead of just using the potion effect which is gimmicky

[true perch]

Okay so

• Make a team for every color I want items to glow
• Upon receiving a drop of a certain glow color, assign the player to that team

correct?

[echo basalt]

Something like that

there are weird issues if you're using the TAB plugin but you can deal with those later

[true perch]

Unfortunately that means that all glowing drops will appear as the same color

[echo basalt]

Uhh no

You assign the entity to the team

Not the player

[remote swallow]

love me a good TAB usage

[true perch]

Oh I see, makes much more sense.

[sage patio]

EventPriority.LOWEST means it runs first or last?

[tender shard]

first

[sage patio]

thanks

[tender shard]

LOWEST, ..., HIGHEST, MONITOR

[remote swallow]

if you do event logic on monitor i will send chocos huskies and mds kangaroos after you

all active developers here will also raid your house

[sage patio]

then i need a little bit more help

i've 2 custom plugins

one which it is my custom armor plugin

[remote swallow]

high and highest

[sage patio]

and another one is a Revive system

[true perch]

👍

[sage patio]

in both of them i'm checking for EntityDamageEvent
in revive: when damage is more than hp --> kill player
in armor: when damage is more than hp --> break armor else getArmor - damage

[true perch]

Any chance you could explain this further?

[remote swallow]

should 1 take priority

[echo basalt]

https://github.com/NEZNAMY/TAB/wiki/How-to-make-TAB-compatible-with-glow-plugins

[sage patio]

what about the armor? the medic should be lowest and armor highest?

[remote swallow]

if armor should take priority, have that on highest, then revive on high

[sage patio]

thats the problem, i don't know which one it should
when some one takes a damage way more higher than his hp, he does not gets knocked by my medic plugin and dies

[distant wave]

any idea how can i store multiple strings and integers like a hashmap in pdc?

[remote swallow]

more pdc or serialize to byte array manually

[remote swallow]

well you probably want ur armor to always apply in these cases right?

[sage patio]

i don't know, i just want to the player do not die immediately and get knocked down

he gets knocked, and dies after it immediately

[remote swallow]

id say players would notice if their armor is meant to block 50% of damage but get 1 shot by a 25 damage item

[sage patio]

i remove the remaining damage from player if his armor is not enough

[remote swallow]

@echo basalt whats the proper sollution for this

[echo basalt]

explain

I can't bother reading

[remote swallow]

2 plugins need to use entity damage event but they contradict eachother in what takes priority

[echo basalt]

uhh

Do you have control over both of them

[remote swallow]

@sage patio

[sage patio]

wdym?

both of them are mine

[echo basalt]

yeah ok so

Think of what the intended goal is

[sage patio]

wanna the event codes?

[echo basalt]

and do it

[sage patio]

uh

what

the goal is if the player takes a high damage, whatever it is, get knocked instead of getting knocked and die
i don't know which one should take priority to prevent this

[eternal valve]

How can I add economyshopgui premium nbt? /// nbt_int: CustomModelData:1036 did not work even though I typed

[remote swallow]

are you using a beta version

[echo basalt]

Well

Are you cancelling the event when knocking the player

[echo basalt]

#help-server

[sage patio]

it seems no, lemme test

[eternal valve]

I haven't seen the new update but I'm on version 4.11

[remote swallow]

might need to add it from nbt data

[sage patio]

yea it works now, thanks
also i changed event priorities to LOW and HIGH

[muted dirge]

first

@sage patio mano yadet miad?

[sage patio]

thanks, the question is already been answered twice

[sage patio]

nope, speak english in here

[muted dirge]

im the guy from Minehack. you used to teach me some basic things

[mint plover]

Hello, someone knows where the cracked property of the decoration pot is defines ?
I search in DecoratedPot data type but not found =/
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/data/type/DecoratedPot.html

I want to set the cracked (or not) of a decorated pot

[sage patio]

well that happened a lot in "minehack", still no, but glad you remember me
how are your codding skills now?

[muted dirge]

I'm trexmine trial developer now

[sage patio]

nice

gl

[tall dragon]

is there a way to get a tileentity from a block without reflection?

cant seem to find one

[near mason]

what are you trying to do?

[tall dragon]

tryna get an instance of TileEntityHopper

[muted dirge]

I failed

[tall dragon]

i did manage to do that but with reflection

[muted dirge]

somehow the entity's change scale is working but you cant see it

[amber stump]

How do I get the inventory of a chest?

[muted dirge]

any ideas how to make it visible?

[lost matrix]

Block -> getBlockState() -> cast to Chest -> getInventory()

[near mason]

ye but what will u do with that?

if ur trying to get the inventory

[lost matrix]

Wrong chest class import

[tall dragon]

im not

im trying to speedup individual hoppers

[muted dirge]

whoa

[near mason]

idk then

[tall dragon]

yea i did it with reflection but was just wondering if there was a way without it

[muted dirge]

😭

@lost matrix you was right

its impossible

[near mason]

whats impossible?

scaling entities?

yes it is

[smoky oak]

I'd like to return the same type of set/collection I'm given. There a better way than doing this?

try{Set<Vector> rSet = locations.getClass().getDeclaredConstructor().newInstance();
        } catch (NoSuchMethodException | InstantiationException | IllegalAccessException | InvocationTargetException e){e.printStackTrace();}

[lost matrix]

?

[smoky oak]

like, other than clone, is there a way to just... copy... the type of the input set

actually clone wouldnt work

[lost matrix]

input of what

[smoky oak]

well I'm passing a Set<location> so that it doesnt only work on 'list of this type'

I'd like to return the same kind of set I'm passing in

[lost matrix]

  public <T> List<T> doSomething(List<T> inList) {
    List<T> outList = new ArrayList<>();
    // Do something
    return outList;
  }

[smoky oak]

the input and output types are different though? this wouldnt work

I'm doing math on a list of locations, which turns into a list of vectors

[lost matrix]

  public List<Vector> doSomething(List<Location> inList) {
    List<Vector> outList = new ArrayList<>();
    // Do your math
    return outList;
  }

[smoky oak]

thats....

a solution

not the one i was going for

[lost matrix]

I dont... understand what you are doing

[scenic onyx]

Hi, I've seen many tutorials on the internet but I still don't understand how to make a project that supports multiple versions. Could you help me?

[tall dragon]

have you read this ? https://blog.jeff-media.com/maven-multi-module-setup-for-supporting-different-nms-versions/

[smoky oak]

public static Set<Vector> toVectorSet(Set<Location> locations){
  HashSet<Vector> returnSet = new Set<>;
  //math
  return (locations.getClass()) returnSet;
}
``` this, just in a way that it works

[lost matrix]

  public <T, U> List<U> translate(List<T> inList, Function<T, U> function) {
    List<U> outList = new ArrayList<>();
    for (T t : inList) {
      outList.add(function.apply(t));
    }
    return outList;
  }

Something like this?

[scenic onyx]

no, i read now

[lost matrix]

Would be used like this:

    List<Location> locations = new ArrayList<>();
    Function<Location, Vector> translation = loc -> loc.getDirection().multiply(2);
    List<Vector> vectors = translate(locations, translation);

[echo basalt]

That's way too much effort

[lost matrix]

public static Set<Vector> toVectorSet(Set<Location> locations){
  Set<Vector> returnSet = new HashSet<>;
  //math
  return returnSet;
}

[lost matrix]

Yeah this is honestly all covered by the streaming api

[echo basalt]

True

[lost matrix]

I think your problem is that you tried to create a HashSet with a Set constructor.
And that your method returns a Set and not a HashSet as well.

[echo basalt]

public interface Transformer<K, V> {

  V transform(K key);

  default List<V> transform(Collection<K> keyCollection) {
    return transform(keyCollection, new ArrayList<>());
  }

  default List<V> transform(Collection<K> keyCollection, List<V> valueCollection) {
    for(K key : keyCollection) {
      valueCollection.add(transform(key));
    }

    return valueCollection;
  }
}

:)

[twilit basalt]

How to change where player has main slot?

[echo basalt]

public List<Vector> transform(List<Location> inputs) {
  Transformer<Location, Vector> transformer = Location::toVector;
  List<Vector> vectors = transformer.transform(inputs);
}

[smoky oak]

ah thats not exactly what i meant

like if i say List<Location> in my parameters

thats not a list, thats some class implementing it

my goal is to return a List / Collection of the same type that's thrown at the method

[quiet ice]

EEEEEEEEEEE, Using lambdas for interfaces not annotated as functional interfaces

[twilit basalt]

nvm I have found out

[echo basalt]

:)

[lost matrix]

public abstract class Transformer<K, V, C extends Collection<K>, P extends Collection<V>> implements Function<K, V>, Supplier<P> {
  
  public P transform(C input) {
    return input.stream().map(this).collect(this, P::add, P::addAll);
  }
  
}

[echo basalt]

generic nightmare

can you even lambda an abstract class

[scenic onyx]

@tall dragon I have seen what is written, but what is the difference between the module: "core" and the module "spigot-1.9.4"?

[near mason]

you cant

thats why i hate BukkitRunnable

[remote swallow]

1.9.4 is version specific while the core isnt most likely

[tall dragon]

core holds stuff like interfaces and spigot-1.9.4 implements those interfaces with version specific code

[scenic onyx]

1.19.4

[remote swallow]

same thing applies

[tall dragon]

im so confused i have a common module that shades a library, then when my other module shaded the common module it shades that library again. so i end up with the same library twice in different locations

why is that happenin

[lost matrix]

Well in most cases lambdas are a hacky approach anyways.
If your lambda is longer than 3 lines you should write an implementation
or at least a method reference.

[remote swallow]

you relocate it

[lost matrix]

^

[remote swallow]

in both places

[tall dragon]

rlly....

whyyyyyyyy

[remote swallow]

if you shade it in common, dont shade it in other

[scenic onyx]

So "core" is the heart of the code but "spigot-1.19.4" is for implementing NMS in the code. Right?

[remote swallow]

yea

[tall dragon]

i dont

i dont even have it as dependency

but it still shades it

[remote swallow]

anyone know of royalty free svg pages

[tall dragon]

only common has it as dependency

[remote swallow]

transitive depdency then

[tall dragon]

what does that mean

[remote swallow]

another depdency also shades it

[near mason]

why is BukkitRunnable an abstract class

and not an interface

[tall dragon]

i woulnt know which one

[lost matrix]

Because it has fields. It wraps the bukkit task it is creating

[tall dragon]

only common has xseries as dependency

or should i not be relocating in common then

only in core

[shadow night]

Doesn't BukkitRunnable have like .runTask() and stuff?

[near mason]

ok

[twilit basalt]

Do I have to register event (custom event) in main class?

[lost matrix]

no

[twilit basalt]

why is there method to do that then

[lost matrix]

You can register it wherever you like

[near mason]

oh you mean that

[scenic onyx]

Because is Otherwise?? i have do all...

[twilit basalt]

there should be why it is there

otherwise it should be deprecated and removed

[lost matrix]

To be more precise: You dont need to register custom events at all.
You can just fire them whenever you like.

[shadow night]

Bukkit API is amazing

Just so simple

[lost matrix]

ExampleEvent exampleEvent = new ExampleEvent("Some message");
Bukkit.getPluginManager().callEvent(exampleEvent);

[twilit basalt]

yeah I know how to call it

just why it is there also method to register events

[shadow night]

Ig to register a listener?

[opal carbon]

yeah

[twilit basalt]

I am talking about registerEvent

not about registerEvents

[smoky oak]

why the hell is this not throwing any errors

[twilit basalt]

oh nvm

I see

xDD

[opal carbon]

to make it only listen to a specific event

[twilit basalt]

yeah

[opal carbon]

javadocs hold the answer

[twilit basalt]

looks little useless to me but okay

[lost matrix]

You should pretty much always use the .registerEvents(Listener, JavaPlugin) method

There are certain cases where the other methods make sense

[shadow night]

I remember I recently coded in bukkit for mc b1.7.3 and it had a different implementation of event listeners

[remote swallow]

anyone got tips on how i could change this to not just be blank or have stuff non related

[near mason]

whats that?

[smoky oak]

fuck's a 'not thread safe' list

[lost matrix]

A list thats not thread safe. Most of javas collections are not thread safe.

[smoky oak]

wait is this that 'lock before editing' thing?

[remote swallow]

docusarus

[lost matrix]

You can create a lock. Its basically a ticket which lets a thread edit an object.
And only one thread at a time can have a ticket. If the others come and request
a ticket but another thread is currently in possession of this ticket, the other threads
block and wait for the ticked to be released. Then the next thread can come and obtain
this ticket.

This is known as a lock or mutex

[remote swallow]

im so confused

[near mason]

I remmeber that there was a thing like Collections.threadSafe(collection)

I saw it on johns video

About vectors

[ivory sleet]

u prob mean the synchronized wrapper

[near mason]

I dont remember

Vectors are thread safe

[lost matrix]

They are?

[fervent robin]

How do you set the ID of an item stack? before you could use #setDurability() but thats deprecated

[smoky oak]

pretty sure they're not

[ivory sleet]

java.util.Vector

they mean

+java.util.Stack

[lost matrix]

Ah. Those are kind of thread safe. But not really.

[ivory sleet]

they are thread safe

but not necessarily atomically safe

[lost matrix]

Well, dont they just have synchronized methods?

[smoky oak]

ah i was looking at the bukkit vectors

[ivory sleet]

idk

i just know they are thread safe

[remote swallow]

web dev confuses me so much

like theres a white block that i cant figure out how to change the color of

[smoky oak]

oh now that im looking at the source

what's '@serializableas("Vector")' mean?

its not turning into one

[remote swallow]

it saves it as !== in config

serialize turns it into a map string that set can use

[fervent robin]

soo

[lost matrix]

what do you mean by ID of an itemstack?

[remote swallow]

i did it, go me

[fervent robin]

like yk how they had numbers to show which color or which variant an item is?

do they not do that on 1.20 anymore? I finally switched from 1.8 to 1.20

[ivory sleet]

well

yesnt

durability still exists

[remote swallow]

this looks better

[ivory sleet]

but like

for coloring and other stuff ItemMeta covers that

or different material types

since magic values bad

[lost matrix]

No, those where dropped half a decade ago because magic numbers are bad.
We now have proper classes with named methods to modify ItemStack variants.

[near mason]

Why is reflection the last option?

Is it slow

Is it dangrrous?

[mortal hare]

its mostly slow

[lost matrix]

Its, slow
I breaks easily
It relies on meta information

[mortal hare]

and its really not portable

[fervent robin]

I see how would I read the type and set the type?

[mortal hare]

it makes your code dependant on the names of the fields and methods

[lost matrix]

Give an concrete example pls

[mortal hare]

i disagree that magic values are bad tbh

[near mason]

Thank you

[lost matrix]

If you are not careful then a single reflection can take upwards of 200ms and ruin your TPS all by itself

[near mason]

oof

Yeah but i heard spring boots uses reflection

[fervent robin]

I have a wool item stack. How do I get which color it is and how do I change which color it is?

[mortal hare]

it does for annotation processing

[lost matrix]

?

[smoky oak]

Should i have one class named 'Shapes' procuding geometry for different shapes, or multiple classed each named after the shape the only method it would have would produce? I'm not sure which route to take here

[near mason]

Ok

[mortal hare]

retrieval of things are faster when using magic values rather than registry classes with strings as a keys

[river oracle]

how are magic values not just bad?

[mortal hare]

iteration 30 chars vs 1 32 bit integer check

[ivory sleet]

dude

constants

[river oracle]

what about constants

[ivory sleet]

and runtime inlined local variables

by JIT

[mortal hare]

https://www.youtube.com/watch?v=fz3Td2zlgro

you should see this

[smoky oak]

i saw it

[ivory sleet]

yes dovidas data oriented programming is ofc a paradigm u have to consider

but like

readability is just really important

[lost matrix]

"retrieval of things" what does that mean?
You mean runtime speed? What is faster.
Registry classes are not the only method of eliminating magic values.

[ivory sleet]

especially when u deal with the amount of state minecraft has

[lost matrix]

Magic values are absolutely evil

[ivory sleet]

I mean sure object orientation sucks anyway

[smoky oak]

since you're apparantly either a wizard or a storyteller, which of those is evil?

[ivory sleet]

but since minecraft now is object oriented we might as well do it good and not bad

[mortal hare]

i get it why minecraft switched from ids to namespaces, its due to make adding new blocks and states easiers for modders, so that they wouldnt rely on some strange id system like 2500:14:32

[ivory sleet]

not only

[mortal hare]

but still it wasnt really a problem that was very bad

[ivory sleet]

Abstract factory maybe? lol

[smoky oak]

hm that gives me an idea

[lost matrix]

Having to remember random numbers is a big problem when programming

[mortal hare]

hashmap of strings, vs index based retrieval

[subtle folio]

87.. 52.. 56?

[mortal hare]

for you to decide which is faster

[smoky oak]

i'm likely to generate more than one shape at once, so having an interface thats implemented by the classes and has a method named 'generate' or smth

[subtle folio]

namespaces are much needed

[mortal hare]

that's why enums exist

[near mason]

Spigot uses reflection to load plugins right?

[ivory sleet]

enums are evil

[mortal hare]

which have ordinal()

[mortal hare]

then Spigot and Bukkit API is too

[ivory sleet]

yes

but it isnt spigots fault entirely

mostly bukkit

[lost matrix]

Each wool color has its own Material

[ivory sleet]

well I think magic values are bad in general

[near mason]

Whats magic values

[mortal hare]

Magic values in an int type for me is bad, but when you have an Enum to denote those or preprocessor defines i dont see a problem with them

[ivory sleet]

myFunction(1,2,3,4,true,(byte)9,0x1111) etc

just pure scalars passed to a function

[lost matrix]

A number in code which has no associated name

[near mason]

Ok

[ivory sleet]

where u have no idea what those scalars will do

[ivory sleet]

enums are great except that they are not, they prevent open closed principle, more often they do become a dependency magnet which is just clumsy

[river oracle]

unsure why magic numbers would ever be a positive. They just create confusion. I always document magic numbers into well named constants

[ivory sleet]

I have had to recode half of my minecrafts recipe system in my mod just because stupid enums
