what method is canDestroy under hasItemMeta in Itemstack

spare marsh Nov 14, 2021, 1:54 AM

#

Question, so I am creating an class called Inventories. This class has the task of returning several inventories, depending on the one you want. When you get a certain one, the items in it are set by calling method that would generate them. Every time it generates the items an item to create them are called. For example a displayPane would be java private ItemStack getPane() { ItemStack item = new ItemStack(Material.YELLOW_STAINED_GLASS_PANE); ItemMeta meta = item.getItemMeta(); assert meta != null; meta.setDisplayName(" "); item.setItemMeta(meta); return item; }

Do you think something better would be to initialize these items since they won't change when an instance of the inventories class is created? Create a non static initializer maybe that would save this to avoid creating them again every time this class is accessed?

quaint mantle Nov 14, 2021, 1:56 AM

#

spare marsh Question, so I am creating an class called Inventories. This class has the task ...

correct

#

public static final ItemStack i =

#

then create an itembuilder class

ivory sleet Nov 14, 2021, 1:57 AM

#

First of all, assert won’t do anything if you don’t have a specific jvm flag enabled, secondly what do you mean by non static initializer? It probably doesn’t matter here, however you probably want to just cache the ItemStack in whatever way, although the creation of ItemStack is quite superficial in terms of memory and speed, it’s more over how it gets processed and converted to nms.

misty current Nov 14, 2021, 1:57 AM

ok so for some reason if you set the damage in an entitydamageevent to 0 and set the health of the victim to 0 and the victim is a player, it dies twice

sending the death msg twice and calling a playerdeathevent twice

That does sound like a bug

Maybe worth reporting

misty current Nov 14, 2021, 1:59 AM

it's 3 am and my brain is frying because of this stuff

#

uh- i am on uh- 1.8

#

is that a known issue

#

from 1.8

ivory sleet Nov 14, 2021, 1:59 AM

#

Although it’s basically you that triggers an event which proceeds to make another event recur

#

Idk if it still is an issue, if you’re on 1.8 that is

#

Very possible it has been patched and dealt with then

misty current Nov 14, 2021, 2:00 AM

#

oh actually i guess it kind of makes sense but still should be a bug

#

well the way i was handling damage was a bit sketch anyways so i should change it

spare marsh Nov 14, 2021, 2:01 AM

ivory sleet First of all, assert won’t do anything if you don’t have a specific jvm flag ena...

I know assert will not do anything but it highlights it and tbh I hate it because it looks ugly on the code so I just put it in 😭. And I mean just for example

public class ToolsInventory() {

private itemStack goBack;

  {
    goBack = getGoBackItem(); etc...
  }

}

Just initialize it when the class is created

ivory sleet Nov 14, 2021, 2:02 AM

#

The set of fields you define in your class is limited to whatever they’re sings they’re known at compile time to a certain extent

#

Having a map would make your cached items changeable at runtime more flexibly

#

As you could easily put and remove new items into the cache

spare marsh Nov 14, 2021, 2:03 AM

#

well yes but it is a GUI

ivory sleet Nov 14, 2021, 2:03 AM

#

And the cache is usually something like a HashMap

misty current Nov 14, 2021, 2:04 AM

#

patent horizon but ive concluded i absolutely have to have one

what do you need it for?

spare marsh Nov 14, 2021, 2:04 AM

#

so the ones I would initialize would be only the bottom items

#

Like the GUI options

#

so those I want to initialize at first but the items on top would be the ones that change

#

For example

ivory sleet Nov 14, 2021, 2:04 AM

#

spare marsh well yes but it is a GUI

Just because it’s a gui doesn’t mean you can’t make it into a more useful cache

i even tried making the fishinghook parse as a projectile

ivory sleet Nov 14, 2021, 2:11 AM

#

Well, to be perfectly clear, if you want to make it enterprisy, usually we separate business requirements (aka the logic) and stuff like gui, storage etc.

Anyways I don’t have a good knowledge regarding your plugin precisely however what I’d do is to encapsulate, in this case, an ItemStack[] (array) with the size nine which maybe represents the nine items at the bottom. Then you have your inventory instance. Whenever you update the array, you’d then go on to update the items inventory as well. Of course this requires you to be disciplined, but yeah, that’d be one way.

Another way would be to completely have the logic of the gui in one class. So essentially you might want to have an ItemStack[] with the size of 56 if that was your inventory size. Then have the class with some useful functions to turn the pages, change items, or whatever you wish to do. Then make sure whatever is done with the functions gets reflected onto the actual gui. Which might be done through another class.

the goal is to make the plugin let players mine bedrock with any tool that has the meta property of can break bedrock

waxen plinth Nov 14, 2021, 3:24 AM

#

I don't think there's a property for that in ItemMeta

#

Alright, you don't need to actually set the property for that

#

You could add it in the lore and/or store that property in PDC

grave hound Nov 14, 2021, 3:26 AM

waxen plinth You could add it in the lore and/or store that property in PDC

lets use lore then

waxen plinth Nov 14, 2021, 3:26 AM

#

Great, that should be simple enough

#

If you want an item to have that property, you can just add a line of lore like &cBreaks bedrock or something

#

Then you can just check if the lore contains that line

quaint mantle Nov 14, 2021, 3:27 AM

Yes because it's the method that checks if an element is in a list

You have to understand the logical difference between checking if something is equal to a list and checking if the list contains an element

You're using 1 &, which checks every condition. Tool is null, but then it's going to tool.getItemMeta(), but tool is null

So... use && instead.

You should pretty much always be using &&

quaint mantle Nov 14, 2021, 10:58 AM

#

bukkit required every event to have a handler
the blockevent doesnt have handler = dev didnt intend it as a normal event
the reason for that is it is just a template for other block-related events, as it is an abstract.

so ive made a bot (nms) and im able to make it move but im also able to move it through blocks. if i want to make it have collision, do i have to do that myself

chrome beacon Nov 14, 2021, 12:28 PM

#

Depends on how you made the bot

near shoal Nov 14, 2021, 12:29 PM

#

its an artificial player so i have to send packets for it do anything

chrome beacon Nov 14, 2021, 12:31 PM

Yeah sounds like you need your own collision then

#

Or try to find where vanilla calculates it and see if you can use it somehow

near shoal Nov 14, 2021, 12:33 PM

#

is there another way i could have made the bot to not need to implement my own collision

chrome beacon Nov 14, 2021, 12:35 PM

#

Simply don't use packets and register it like a normal player would be

#

Or you could have a bunch of JS bots with Mineflayer

#

Depends on what you're trying to do

#

Personally I'd just use the Citizens plugin api

#

Since they handle all of it for you

The world shoudl be valid even if the player is stale, as its just a reference and world references do not change

It would be safest to get a fresh player though

it seems it gets the coords from NMS entity object reference

i'll just make a if statement

misty current Nov 14, 2021, 1:07 PM

hey, i've noticed that when you set the damage to 0 in an EntityDamageEvent and set the health of the victim to 0, the player dies twice, sending 2 death msgs in chat and also calling EntityDeathEvent twice

#

this doesn't happen for other entities tho

mortal hare Nov 14, 2021, 1:12 PM

sounds like a bug

send your code

& are there any other plugins

or listeners

eternal oxide Nov 14, 2021, 1:15 PM

#

are you canceling the damage event?

#

if not, you are setting the players health to zero, the player dies. The event continues and applies zero damage and makes teh player die again

misty current Nov 14, 2021, 1:17 PM

#

oh that makes sense

#

i'm not canceling the event

#

so i should cancel the event if the health of the player will reach 0

eternal oxide Nov 14, 2021, 1:18 PM

if you are managing teh death yourself, yes

test with getFinalDamage() to account for armor

this is my code btw

you should have deprecated warnings in that code

use attributes

#

i don't, i'm on 1.8

#

else i'd use java 16 and the if with instance checks would not be painful to read

basically what this code aims to do is create a custom damage system calculated by pvpManager#calculateDamage()

you should specify in your plugin.yml what plugin dependencies you have

Quick question relating to entering the plugin API version.
My 100% sure my plugin works on prior versions of minecraft. Even tho i'm building it targeting the latest 1.17.1. Which version should I enter inside the plugin.yml?

eternal oxide Nov 14, 2021, 3:17 PM

#

the lowest API you want to run on

maiden mountain Nov 14, 2021, 3:17 PM

#

I heard its like 1.13 right?

ancient plank Nov 14, 2021, 3:17 PM

#

1.13 is lowest api-version

maiden mountain Nov 14, 2021, 3:17 PM

#

Yeah, i have that right now

eternal oxide Nov 14, 2021, 3:17 PM

#

if you want 1.13, build against 1.13 too

quaint mantle Nov 14, 2021, 3:17 PM

#

maybe if you want to support 1.8+ then remove the api-version i think?

ancient plank Nov 14, 2021, 3:17 PM

#

if you remove it it'll just go "brrt brrt plugin using legacy support!"

maiden mountain Nov 14, 2021, 3:18 PM

#

So I got it right. Thanks for the response 👍

maiden mountain Nov 14, 2021, 3:18 PM

#

eternal oxide if you want 1.13, build against 1.13 too

I will just test it on a 1.13 before actually re-building it

@misty current This should answer your question (Untested):

  String itemName = new ItemStack(Material.DIAMOND_HELMET).getItemMeta().getDisplayName();

misty current Nov 14, 2021, 3:27 PM

#

getdisplayname returns null if the item doesn't have a custom name iirc

eternal oxide Nov 14, 2021, 3:28 PM

#

I guess you could Bukkit.getItemFactory().getItemMeta(material).getDisplayName(); So long as you check the material is a valid item.

maiden mountain Nov 14, 2021, 3:29 PM

#

I was about to post the same code @eternal oxide ahaha

misty current Nov 14, 2021, 3:29 PM

#

thanks i'll give it a try

#

with checking if it is valid do you mean checking if it is not null?

maiden mountain Nov 14, 2021, 3:30 PM

#

Yeah, store the item meta inside variable and null check it

#

Just to be safe

#

Because the getItemMeta method is nullable

misty current Nov 14, 2021, 3:30 PM

#

oh yea the methods where i use it already check if the item is not null/air

maiden mountain Nov 14, 2021, 3:33 PM

**What's the best way to efficiently read/write date to a local file upon onDisable? **
Up to this point I've only used SQL to store data for my server. However I'm interested in writing/reading local data. onDisable I want some data to get instantly written to a file so the data doesn't get lost, and read it when the server reboots to take the correct measures.

depends on way you clone it, see https://www.baeldung.com/java-copy-hashmap. The way you showed WILL NOT clone values and keys, so they will point to the same value. If you want them to not point to the same value use external libraries or write your own implementation (i.e. Apache commons lang: SerializationUtils.clone(originalMap), though every element in map you want to be deep copied must implement Serializable).

Hello, I wanted to know if there was a way to run the code inside a scheduled task on a command. For example if I run /endtasks it will end the scheduled tasks but still run the code inside of that task

#

Right now I am using Bukkit.getScheduler().cancelTask(task); but that doesn't actually run the code inside the task

torn shuttle Nov 14, 2021, 7:14 PM

#

nor should it

#

but how about

tranquil viper Nov 14, 2021, 7:14 PM

#

Yes I know it shouldn't

torn shuttle Nov 14, 2021, 7:15 PM

#

you extract the logic inside of the task, put that in a method, then run it AFTER you cancel the task

tranquil viper Nov 14, 2021, 7:15 PM

#

I don't know exactly what task I am running though, I guess I could track this though

torn shuttle Nov 14, 2021, 7:16 PM

#

you are referring to the task in some way

#

if you want a systematic approach to this you can also create your own task system with your own cancellation system in it

old cloud assign a value to the variable for example `ArrayList<Player> playerList = new A...

Anyway to explain why you don't store Player instances in collections like this:
It's incredibly memory inefficient as you are storing a reference to a large object, therefore stopping the GC from claiming it when it is no longer in use (which I imagine Player instances are no longer in-use when they are removed from worlds/servers or whatever, but I'd have to confirm that myself)

torn shuttle Nov 14, 2021, 8:09 PM

#

also player instances change when they log out and log back in which tends to be a way more pressing issue

lavish hemlock Nov 14, 2021, 8:09 PM

#

Oh yeah that's also really bad.

torn shuttle Nov 14, 2021, 8:10 PM

#

one of these breaks the plugin functionality and the other one saves you a few bytes, maybe start with the more important one

lavish hemlock Nov 14, 2021, 8:10 PM

#

UUIDs are harmless though, so you should pretty much always use that over storing Players.

golden turret Nov 14, 2021, 8:10 PM
