It probably only came up because he was trying to return teh items to the player from teh crafting grid

deft sedge
#

IT doesn't work

#

sdofijefio

eternal oxide
#

lol, it works here

deft sedge
#

ill send what i did

young knoll
#

Yeah I had a small feeling this wasn’t the issue

deft sedge
#

queen dragonBOT
eternal oxide
#

I tested with a single item and multiple in different slot

deft sedge
#

yea me 2

young knoll
#

I imagine spigot has a way to keep created inventories referenced

#

What spigot version are you on

#

And is it up to date

deft sedge
#

1.16.5

eternal oxide
#

That code I sent you exactly as is worked perfectly

#

all in the same class

lost matrix
#

Why does it have to be a Fireball?

deft sedge
proud sapphire
#

can someone help me with detecting and cancelling number key shortcuts

young knoll
#

downloaded

proud sapphire
#

inventoryclickevent doesnt seem to detect it

deft sedge
lost matrix
#

You can also use other projectiles and disable their gravitiy. Then listen for the ProjectileHitEvent and create an explosion.

eternal oxide
deft sedge
#

ok

lost matrix
brittle badger
#

yes

eternal oxide
#

I added a login event so the inventory opens as soon as you join the server

deft sedge
#

I convinently forgot how tomake a new project

#

edfdsfdfefs

#

also i might've selected paper plugin in creation but idk

#

I'm using intelij btw

#

i do have a paper plugin tho

eternal oxide
#

you can put that code in yrou current plugin

#

the class has events registered so just put it in exactly as I gave you

young knoll
deft sedge
#

k

#

imma do tahat now

proud sapphire
eternal oxide
#

there is a seperate event for that...

proud sapphire
#

what's the event?

eternal oxide
#

looking

#

Um, I guess not. Old age moment. I could have swore there was a specific event when transferring between inventories

proud sapphire
#

hmm

brittle badger
#

@lost matrix so are there any alternatives?

young knoll
#

There is InventoryMoveItemEvent

#

But that’s for hoppers

eternal oxide
#

its for entities too

young knoll
#

What entity does that

#

Hopper Minecart?

eternal oxide
#

I'd test if it fires for a player too

lost matrix
proud sapphire
#

it is actually firing inventoryclickevent but cancelling it does nothing

young knoll
#

Creative mode?

#

Because creative mode is jank

proud sapphire
#

nope can do it in creative and survival

eternal oxide
#

creative has its own events

brittle badger
young knoll
#

Yeah I think the server puts more trust in creative players

lost matrix
brittle badger
#

I use gradle

deft sedge
#

@eternal oxide it's ur trigger, it works perfectly but it's basically the same WTF is wrong with mine?

brittle badger
#

i do forge modding as well so used to gradle

#

but maven and gradle are similar right?

eternal oxide
deft sedge
#

ok, so should I put the command and the other thing in the same class?

lost matrix
eternal oxide
#

you could as its all related

deft sedge
#

ok

young knoll
#

Im still dubious on that one

#

But if it works who am I to question it

brittle badger
brittle badger
bright jasper
#

Can i get a chatcolor from a string that is like

#

&x&f&f&f&f&f&f

#

I need to get a chatcolor from a toStringed ChatColor basically

deft sedge
#

once I implemented it in the same class as the command, the first slot works, but only if it has to return one item stack 🤦‍♂️ @eternal oxide

eternal oxide
#

for me it works with any number of slots occupied

proud sapphire
#

it was because .getCurrentItem() returns null for some reason if you hotkey

deft sedge
#

@eternal oxide if it's not too much trouble, can u try urs with the command as the trigger, that seems to be the only difference

#

?paste

queen dragonBOT

#

Having an issue, I have a bungee chatcolor(HAS to be bungee for what im doing)

#

And I am using the team api to do team.setColor

#

which wants a bukkit one

#

how i do

heavy sapphire
#

Would it be a bad idea to, in the onEnable() method, store getProxy() in a static variable so I can access it from a static context? I need someway to convert online player's usernames to UUIDs. I don't want to use the mojang api because its rate limited.

eternal oxide
#

You pass your plugin instance via dependency injection

quaint mantle
#

how to check if the block breaked in the BlockBreak event has been breaked by a player or a villager

eternal oxide
#

Do you mean a fake player/NPC as villagers don't fire the blockbreak event. I don't believe they can break blocks

quaint mantle
#

when they pickup carrots

#

villager farmer

eternal oxide
#

thats harvestblock not breakblock

#

and again, only players trigger that event

quaint mantle
#

and is this event triggered by villagers

#

onPlayerInteract

eternal oxide
#

the event name tells you all you need to know

quaint mantle
#

is villager considered by players

eternal oxide
#

no

Will CompletableFuture resolve CME?

#

I have a method to create a data each player and save them to the SQL and then cache the data into a Map with async task but It's giving me CME.

chrome beacon
#

Use a concurrent map or a syncronized one

eternal oxide
#

you can;t modify from two threads without synchronizing

summer scroll
#

Can I save the data into sql with async and then cache them sync?

ivory sleet
#

cache them sync?

#

I mean quite frankly you should probably use a concurrent data structure and just cache it on the same thread

eternal oxide
#

use a Future to save/load to the SQL. then run sync to put it in your cache

summer scroll
# 
CompletableFuture.runAsync(save/load).thenAccept(put in cache);
eternal oxide
#

not quite, as the thenAccept is still Async

ivory sleet
#

Wrap the callback with the BukkitScheduler like
.thenAccept(o -> {
Bukkit.getScheduler().runTask(plugin, () -> {
this.cache.put(...);
});
});

eternal oxide
#

yep

ivory sleet
#

pey (:

summer scroll
#

oh okay, i thought thenAccept is sync because there is thenAcceptAsync too.

eternal oxide
#

its on the thread that completes the Future

summer scroll
#

ah okay

ivory sleet
#

Well it’s sync with respect to execution of the supplier/runnable that is declared ahead of the callback you declare.

hushed spindle
#

when you do YamlConfiguration#get() which returns an object I should be able to check the instance of that object right, when I use config.get("somename") on for example

somename: 30.0

will this object be an instance of a string or a double or something else

eternal oxide
#

it will return an generic Object. use the correct getter for your type.

hushed spindle
#

no i get that but im trying to generate abstract objects with configurable options for each and some of those options are string or doubles or lists

#

was wondering if i could just cast the generic object to the option type it needs instead of making a whole bunch of type specific abstractions

eternal oxide
#

Is there a reason you are not using ConfigurationSerializable?

hushed spindle
#

its not what im looking for

ivory sleet
#

It has stuff like getString getInt getList alr?

#

But yes you should although it may be the case a boxed primitive is returned

#

That’s probably guaranteed

knotty arch
#

hey can someone take a look at smth for a plugin I'm developing and tell me if it seems like the best way to implement it

ivory sleet
#

Sure

knotty arch
#

Alright 1 sec

hushed spindle
#

this was all i needed so it'll be fine

unknown.png
ivory sleet
#

Interesting

eternal oxide
ivory sleet
#

Ftr it’s pointless to reinvent the wheeel

hushed spindle
#

it wont be an issue anyway with how its implemented

sage dock
#

pls help

eternal oxide
sage dock
#

I need to add to my jar file which I have on my computer
not to the global repository

eternal oxide
#

Instructions are on there about how to make your own patches

sage dock
#

okay

summer scroll
#

So I have a save method and it will get a new connection, and it the method will run another method that will get a new connection, should I pass the connection on the parameter instead?

ivory sleet
#

Do you use hikari ?

summer scroll
#

nope

#

it's kinda my first time using sql

ivory sleet
#

Ah well it may still be of your interest to have a look at hikari connection pool then

eternal oxide
#

just have a getConnection(). In that method you check if the connection is good, if not create a new one.

summer scroll
summer scroll
ivory sleet
#

Elgar means you should have one connection at the time

summer scroll
#

And maybe change to something like this

public void insert(Connection connection, String uuid, String value){}
public void update(Connection connection, String uuid, String value){}
ivory sleet
#

Then check if it’s a good one, if it is keep it else may wanna close and get a new one

#

Aglerr if all of those methods are in the same class then maybe it worth putting the connection into a field and use that field instead of passing it through method parameters

eternal oxide
#

With yoru code you are not dealign with the connection or anything if it errors

summer scroll
#

Now I'm confused xd

ivory sleet
#

Then maybe inject the databasemanager instead passing the single connection ?

summer scroll
#

I'm currently moving everything to a manager class and let's see how it turns out.

#

Thanks for the help.

@cunning cloak you can just open new menus/redraw your current menu with different items and stuff

summer scroll
cunning cloak
glass sparrow
# cunning cloak How would I do that?

Set an item to green wool and use your method of checking for a click, then the click method will be to open a different gui or just change the items of one gui if you dont want your mouse resetting, and then treat the second opened gui as a standalone thing where you can click anything you want

#

treat them like folders on a desktop, you can open a folder then it shows you a whole list of new folders to open

Hello everyone !
Would it be possible to have some help please?

I would like to make a tool (like in WildTools) with a durability system visible in the lore of the item.
Something like that :

This item allows you to do something!
Durability: XX

I just have one big issue for me: How do I get the remaining durability of the item?
And how could I modify it?

This question seems easy, but I would like it to be done by being fully configurable in the config ...
But I have no idea which method to have ...

Thank you !

# olive valve i know alot of java programming but spigot doesnt make sense to me. how can i le...

Spigot is just java. There are some higher concepts but if you know "alot of java programming" then you will get there by just trying a bit.
There are 3 fundamentals that are a bit different from spigot programming then usual java programming.

  1. Your entry point is not defined by a main method. Your entry is either the onLoad() or the onEnable() method inside of your JavaPlugin class.
    The JavaPlugin class has one instance that is bootstrapped by the spigot classloader. Meaning you never create an instance yourself but use the one accessible in the onLoad() or onEnable()

  2. Event based programming. Its a bit hard to grasp how the event handling works if you dont know reflections and the actual purpose of the EventHandler annotations.
    All you can do is read up on how to use the event api and learn as you go.

  3. You only program against an API and dont really have any classes but only abstraction to program against.
    There is also a lot happening in the background regarding the plugin.yml

Commands are actually one of the things which are quite easy to understand if you know java quite well.

lost matrix

Define "where the aim is"
You can get the clicked BlockFace quite easily.

The direction (vector) if the click is basically the direction of the players eye location.
If you want an exact intersection then you might need to ray trace.

You extend the Enchantment class and register it using the same class. You would need to set a boolean in the class via reflections before. There are def tutorials out there.

You just go through all fields from top to bottom of the packet and then try to fill each field with the right data.

Note: In some cases the actual packet doesnt quite match with the one represented in the protocol.
In this case (normally discovered through "not such field" exceptions) you would need to look at the actuall structure of the packet in the nms source code.

viscid dune
#

can someone help me i wanne add a api to a plugin

#

but how ?

onyx shale
#

either slap the jar as dependency or add it to maven

viscid dune
#

idk how to do that

#

if i send you the plugin would you add a api for me ?

mortal hare
#

Maven, Gradle, Import jar by using IDE build system, Classpath's

viscid dune
#

please

mortal hare
#

choice is yours

onyx shale
#

well for start say waht you code in

viscid dune
#

its for a mc plugin

#

i got it from google

#

so

mortal hare
#

what IDE are you using

onyx shale
#

so you are not a dev

viscid dune
#

true

onyx shale
#

by that i mean ur not coding

#

right?

viscid dune
#

but i need a api in it so i can get in on my scoreboard in minecraft

#

true

#

is that a problem ?

onyx shale
#

well to connect a api someome has to code it

#

if the plugin doesnt alrdy have that feature you need someone to code it in

viscid dune
#

idk if it has

#

where can i find it what file ?

onyx shale
#

either plugin store page or if its mentioned somewhere

#

if not you cant rly look into a file to figure out

viscid dune
#

it says it is in

#

but where do i find it ?

#

what the api is

onyx shale
#

if it has it then simply having the api in the plugin folder should do the trick

#

example scoreboard to use placeholderapi..

#

nothing more than having both in the plugins oflder

viscid dune
#

not it in so the owner lies

#

idk if you wanne do it

#

but would you code it in it for me ?

Oh thats bad. It doesnt return a field. So you have 2 things you could do.

  1. Extend EntityFireball and overwrite the W_ method
  2. Inject bytecode that changes the return value of that method.

which one is less breaking

im guessing the 1st option

huh

thats really weird

also why do the fireballs have no collision]

lost matrix
#

No idea. There is probably a class that should be extended rather than EntityFireball.
I just realised that EntityFireball is abstact

brittle badger
#

entity dragon fireball overrides W_ and that makes it so that there is no fire

oh wait

maybe i can add listener for entity combust event

and then cancel it if its my specifi fireball

could someone tell me why this event cancel isint working please?

it works with any other entity, but the ender dragon

what do u mean by isnt working

probably cuz the ender dragon has a special case where it just spawns the xp orbs instead of the standard way

sharp bough
#

yea it spawns the exp orbes a few times, not like normal entities

it handles exp differently

you will need to make make your own enderdragon entity

and override the method where xp is handled

maybe they will add an event for it or something

question about objects

#

if i may interrupt

#

so I talked a bit about this yesterday, but I'm working on an RPG-engine plugin-thingy and I need a way to serialize and load data to and from a file

#

There are objects like Quest which might contain information like the level required, objective list, etc

sharp bough
#

In addition to this, the ender dragon actually dies over the span of 200 ticks (10 seconds), and drops experience each of these ticks.
could i use that and make a loop that runs for 10 seconds to delete all exp orbs?

quaint mantle
elfin pilot
#

it does

#

well

#

json

quaint mantle
#

gson is a wrapper for json that lets you serialize and deserialize pojos

elfin pilot
#

there are also objects like Creature which specify information about a certain mob, like its health, defense, what have you

#

ah, alright, but i have a little more to explain, sorry

#

what's to stop me from creating one object that pairs a String with JSONObject

#

the String acts as a key for the JSONObject, and each JSONObject is grouped into a bigger one when the server shuts down

#

instead of creating a Creature and Quest and Enemy and Item with their own respective getters and setters

#

let me paste some code here as an example

#

something like this


public class JSONKeyComponent {

    private String key = "";
    private JSONObject obj;
    
    public JSONKeyComponent(String keyName, JSONObject json) {
        key = keyName;
        obj = json;
    }
    
    public String getKey() {
        return key;
    }
    
    public JSONObject getObject() {
        return obj;
    }
    
    public int getInt(String keyName, int defaultValue) {
        int value = defaultValue;
        
        if(obj.containsKey(keyName)) {
            value = Integer.parseInt(obj.get(keyName).toString());
        }
        
        return value;
    }

    public String getString(String keyName, String defaultValue) {
        String value = defaultValue;
        
        if(obj.containsKey(keyName)) {
            value = obj.get(keyName).toString();
        }
        
        return value;
    }
    
}

is there a reason for that?

#

using gson you could have something like:
PlayerData (class)
--> Quests
--> Stats
--> Inventory

you would then serialize PlayerData into a file, and it'll contain Quests, Stats, Inventory all serialized as well

#

then you can deserialize the file back into PlayerData
