#

Is it ok if I call the getLocation() from a player obj inside an async task?

#

the player is stored inside a synclist

wraith rapids May 1, 2021, 1:44 PM

#

the location may not be accurate

#

since the fields in Location that hold the position and direction aren't volatile or synchronized

cold field May 1, 2021, 1:44 PM

#

ok thanks

wraith rapids May 1, 2021, 1:44 PM

#

it won't explode, but you might get stale data

you forgot to implement CommandExecutor

quaint mantle May 1, 2021, 2:27 PM

#

quartz anchor May 1, 2021, 2:27 PM

try to replace implements Listener to implements Listener, CommandExecutor

or you can just create new class

quaint mantle May 1, 2021, 2:27 PM

#

#

quartz anchor May 1, 2021, 2:28 PM

#

you see this part?

#

the reason why CommandKit is in red is because there's no class called CommandKit

#

but since your main class is also CommandExecutor, you can replace new CommandKit() with this

Oh. Nice idea. I will try

then use getOfflinePlayer(mail.getSender())

if the returned OfflinePlayer still has a name then its a valid OfflinePlayer and you can check .isOnline()

the team name is 0_owner

eternal oxide May 1, 2021, 5:58 PM

shouldn't this be looping over the values no tthe keys? instance.getTabListSortPriorityTeams().keySet()

you added the names as the value not the key

quaint mantle May 1, 2021, 5:59 PM

im checking for the key

the key is whats in the config (owner) and the value is what the name of the team (0_owner) is

you are registering the team with teamName but you add that to your Map as the value not the key

Like I know it rounds it up, but I don't know how I can stop it from rounding it up
for example, if my intended location is 121, 64, 128, and print my location and go to the intended one, I will get 121, 64, 129, it's rounding it up, completely messing my code up, how can I make it stop rounding it up?

you could make the customnamevisible to false, attach an named armorstand with packets to the entity and just show it to a player if he is within a distance of X

it doesn't automatically update the level of the player

Why 👀

Because I'm trying to give a player a XP reward for something.

and the level of the player doesn't change by changing the XP.

any suggestions?

there is xp and level. xp is distance to next level

setDirection() can be a problem ?

eternal oxide May 1, 2021, 9:27 PM

you are getting the direction and setting it. you are doing nothing with the direction

minor garnet May 1, 2021, 9:28 PM

''setting it'' ? you mean setting a location for a direction ?

eternal oxide May 1, 2021, 9:28 PM

is your e.getDirection() supposed to give a different direction to the location?

what are you spawning?

Hey, just a little question. is there possible to change items display name randomly? By that i mean lets say you had 1 pickaxe in ur hand for like 5 mins, and if you right click on it the item meta changes?

so like just under interactevent or smthing

eternal oxide May 1, 2021, 10:28 PM

#

yes

vital ridge May 1, 2021, 10:29 PM

Ok ty.

#

basically

#

i have to if statements

#

two*

#

if booktype is teleportationbook

#

set books display name to a certain name, and under that i have if book type is dashingbook, set the display name to a certain name

#

and im setting the itemmeta after both of the if statements

#

Is this the right way to do it or i should add them in both if statements?

#

Or how exactly setmeta is used?

#

In this case

olive lance May 1, 2021, 10:45 PM

#

@wraith rapids i can only see the interface method

wraith rapids May 1, 2021, 10:46 PM

that's because you don't have the source

olive lance May 1, 2021, 10:46 PM

#

i been tryna find it for a while

wraith rapids May 1, 2021, 10:46 PM

#

you need to build it yourself

#

the sources aren't distributed publically because they include mojang source

#

and redistribution of that is a no no

olive lance May 1, 2021, 10:47 PM

#

so decompile the actual server jar?

eternal oxide May 1, 2021, 10:47 PM

olive lance May 1, 2021, 10:47 PM

tps is a poor measure of performance

eternal oxide May 1, 2021, 11:42 PM

#

watch TPS but also CPU load

wraith rapids May 1, 2021, 11:48 PM

#

the actual metric you want to look at is mspt

untold rover May 1, 2021, 11:48 PM

#

Is it possible to add Persistent data to a block? eg add a String to a block, and it won't go away even after a restart?

wraith rapids May 1, 2021, 11:49 PM

#

if it is a tile entity, yes

#

use the persistent data container of TileState

#

if it's a regular block, you're fucked

eternal night May 1, 2021, 11:49 PM

#

if you were feeling it, you could try to use the Chunk PDC and kinda go from there

#

tho tbh, that is pretttyyy hacky and will fail the second a piston or something moves the block

wraith rapids May 1, 2021, 11:50 PM

#

that takes a lot of effort to get working properly

eternal night May 1, 2021, 11:50 PM

#

^ yea

wraith rapids May 1, 2021, 11:50 PM

#

with bukkit it's like borderline impossible to even make sure your data for a block gets removed when the block disappears

#

need to have an event listener with like 30 different event handlers

#

and there's still shit that is literally impossible to deal with, like plugins setting blocks

untold rover May 1, 2021, 11:51 PM

#

wraith rapids if it is a tile entity, yes

I am guessing a block of hay is not a tile entity, is there a non persistent way? eg something to add data to a block until the server is restart

wraith rapids May 1, 2021, 11:51 PM

#

it's not a tile, no

eternal night May 1, 2021, 11:51 PM

#

:rip:

wraith rapids May 1, 2021, 11:51 PM

#

tiles are things like furnaces and chests

left swift May 1, 2021, 11:51 PM

#

left swift How can I teleport armorstand to the player with every tick? I tried to create a...

and how can I more precisely refresh the height at which the armorstand is located so that it teleported over the player, because when I walk normally the armorstand moves behind the player without delay, but when I jump or crouch it changes the height a little with a delay

eternal night May 1, 2021, 11:51 PM

#

aww no custom emojis right

untold rover May 1, 2021, 11:52 PM

#

Is there a temporary data storage for blocks?

wraith rapids May 1, 2021, 11:52 PM

#

what are you trying to achieve with this hay block though

#

there's nothing

#

a block is just a few bits in some block palette in some chunk

#

there's no room or capacity for extra stuff to go in there

eternal night May 1, 2021, 11:52 PM

#

There is https://github.com/Flo0/PersistentBlockAPI which might work as long as you don't care about plugins placing blocks

GitHub

Flo0/PersistentBlockAPI

Spigot/Paper API. Used to store persistent block data. - Flo0/PersistentBlockAPI

wraith rapids May 1, 2021, 11:53 PM

#

you could try registering your own tile entities or something i guess

untold rover May 1, 2021, 11:54 PM

#

we are a RP Server, and we use a structure of 3x3 hay blocks for the fire department when a person wants to jump from a building. like a big cushion. and we want the firedepartment to be able to just break the center of the hayblocks, and using the data stored we know if its a structure for the firedepartment or just a normal block of hay

wraith rapids May 1, 2021, 11:54 PM

#

well

#

if you're rp enough, you probably don't have pistons or anything pushing these hay blocks

eternal night May 1, 2021, 11:54 PM

#

^ then chunk pdc might be a valid option

wraith rapids May 1, 2021, 11:55 PM

#

you can probably just store the Block in a map or a set somewhere and associate data with it, or go with the chunk pdc

#

former being transient while the latter is persistent

untold rover May 1, 2021, 11:55 PM

#

does anyone have a ressource that explains chunk pdc

eternal night May 1, 2021, 11:55 PM

#

I mean, it is just a normal pdc

#

¯_(ツ)_/¯

wraith rapids May 1, 2021, 11:55 PM

#

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

#

this but with a Chunk instead of an itemStack

#

both are persistent data holders

eternal night May 1, 2021, 11:56 PM

#

also a few youtube tutorials out there for PDC if you are more of a visual learner

wraith rapids May 1, 2021, 11:56 PM

#

at least on paper, i'm guessing spigot has pulled that from downstream since you're talking about it here

eternal night May 1, 2021, 11:56 PM

#

Chunk PDC ?

wraith rapids May 1, 2021, 11:56 PM

#

yeah

eternal night May 1, 2021, 11:56 PM

#

I think it got introduced in upstream actually

#

killed all worlds it was used on 😂

untold rover May 1, 2021, 11:57 PM

#

okay so once the blocks are moved the pdc is gone right? or atleast the data I added

wraith rapids May 1, 2021, 11:57 PM

#

really? i vaguely remember people raving about it in the paper discord a good while ago

#

no, the pdc is part of the chunk

#

the chunk doesn't give a shit about your blocks

#

you'll have to track them manually

eternal night May 1, 2021, 11:57 PM

#

which is the hard part about this 😅

#

but yeah, paper had a PR open for it, then someone implemented it incorrectly on spigot and it broke every world it touched for a commit lol

wraith rapids May 1, 2021, 11:58 PM

#

average day in the bukkit ecosystem

eternal night May 1, 2021, 11:59 PM

worldly ingot May 2, 2021, 12:07 AM

#

Not sure what ecosystem you're in but I don't recall the last time there was a breaking change in CraftBukkit beyond that most recent one

#

and it was because of an untested PR

eternal night May 2, 2021, 12:09 AM

#

pretty sure it wasn't even too breaking 😂 paper broke, spigot just kindly doubled your chunk size on the disk

#

damn those optimisations paper 😦

worldly ingot May 2, 2021, 12:09 AM

Yeah it was hardly "breaking"

eternal night May 2, 2021, 12:10 AM

so i read up on nms and want to get started with it, seems pretty scary to get into but do you guys think just a small scale npc entity dialogue/quest system would be a nice start? already made a working mob arena with normal spigot

young knoll May 2, 2021, 3:20 AM

#

Maybe, but you can already do that with citizens

#

Or the citizens API

#

It’s easier to start with small things the API doesn’t have access to

#

But generally you don’t need NMS that much

hollow river May 2, 2021, 3:21 AM

#

yeah but i dont want to use citizens, its partly a learning experience for me to get into nms and it's flow

#

What would you use nms for mostly? custom entities like skeletons shooting 2 arrows and such?

young knoll May 2, 2021, 3:23 AM

#

Mob AI, packet manipulation, a few things here and there the API doesn’t cover

hollow river May 2, 2021, 3:23 AM

#

and also yeah im planning on using just spigot and using nms for things i can't use spigot for (i was about to add a boss mob to my arena but found out i'd need nms for more customization so that's how i got into it)

i'll get working on it!

Do we have to check for e.isCancelled() when doing event handlers?

False

is there an alternative to the deprecated InventoryClickEvent#setCursor? it says the reason it's deprecated is because This changes the ItemStack in their hand before anycalculations are applied to the Inventory, which has a tendency tocreate inconsistencies between the Player and the server, and tomake unexpected changes in the behavior of the clicked Inventory.im thinking i should just setCursor in a delayed task...

im not sure actually

opaque mango May 2, 2021, 7:24 AM

ConfigurationSerializable basically means you can serialize it as YML

and YML is for configs, not for data storage, so...

I would ideally serialise it as a byte array

Hello! Anyone help me how to make class that work like Player class? I mean it syncs to every stored player variable. Example if a function contains Player parameter(public void changePlayerName(Player player){...}), if we edit player name vai the variable in parameter, it will affect to the original Player instance right? So, why it does so. And how can I do like this in my own custom class? You understand me?

drowsy helm May 2, 2021, 7:57 AM

#

are you asking how to change a variable?

rigid otter May 2, 2021, 7:57 AM

#

No

dense goblet May 2, 2021, 7:58 AM

#

(almost) everything in Java is passed by reference

rigid otter May 2, 2021, 7:58 AM

#

If so, first, where do Players store?

lilac dagger May 2, 2021, 7:58 AM

#

in a heap

dense goblet May 2, 2021, 7:58 AM

#

changePlayerName takes a reference to your player and sets some values in the memory that the reference points to

rigid otter May 2, 2021, 7:58 AM

#

Eample it store in a list, then where is that list?

drowsy helm May 2, 2021, 7:59 AM

#

i usually have manager classes

#

that hold those collections

lilac dagger May 2, 2021, 7:59 AM

#

all objects separately are stored in a heap

#

if it works as c++

#

which i think it is

rigid otter May 2, 2021, 8:00 AM

#

lilac dagger all objects separately are stored in a heap

No, I just mean, store in somewhat class(and a variable that hold player collection)

lilac dagger May 2, 2021, 8:00 AM

#

ohh

#

yeah

#

it's stored in multiple locations actually

#

you should be careful what'u doing

dense goblet May 2, 2021, 8:00 AM

#

one singular player is stored in only one location no?

#

it is just referenced in multiple locations

lilac dagger May 2, 2021, 8:01 AM

#

yes it's stored in heap with an address

#

nothing else holds but a reference to it

#

a pointer

#

the heap is simply stored when you do
new Object();

#

even if it's not asigned

dense goblet May 2, 2021, 8:02 AM

#

I think Sivann thought when you pass player to a function it receives a duplicate

#

which isn't the case

rigid otter May 2, 2021, 8:02 AM

#

dense goblet changePlayerName takes a reference to your player and sets some values in the me...

But, I try a string it does not work. I just initialize a String variable in User class(for example) and I collect that string in contructor. Then when I modify string in User class or in that original string from class, it doesn't affect each other.

dense goblet May 2, 2021, 8:03 AM

#

modifying a String creates a duplicate I think

lilac dagger May 2, 2021, 8:03 AM

#

strings usually are cached but don't relay on that

dense goblet May 2, 2021, 8:03 AM

#

either that or you are reassigning your string reference

#

if you do:
String s = player.name;
s = "aaa"

rigid otter May 2, 2021, 8:03 AM

#

Ohh

lilac dagger May 2, 2021, 8:03 AM

#

you should always string.equals

#

just use equals

dense goblet May 2, 2021, 8:03 AM

#

then that will just reassign s to a different memory location (that of "aaa")

lilac dagger May 2, 2021, 8:04 AM

#

it'll make the cheap check

#

if it's cached

#

otherwise it'll go deeper to check it

#

i think modifying a string will give you a new String() which is no longer supported by caching

rigid otter May 2, 2021, 8:05 AM

#

Yes, it looks duplicate, you are right🤔

#

But if in parameter, it's not mean duplicate?

lilac dagger May 2, 2021, 8:06 AM

#

if as literal

#

ye

dense goblet May 2, 2021, 8:06 AM

#

so in memory you would have at first:
0xA: Player
0xB: -some data
0xC: -name: "bobb123"
0xD: -more data
0xE: String s: points to 0xC

then you run s = "aaa"

now in memory you have:
0xA: Player
0xB: -some data
0xC: -name: "bobb123"
0xD: -more data
0xE: String s: points to 0xF
0xF: "aaa"

lilac dagger May 2, 2021, 8:06 AM

#

String a = "a";

and
String b = "a";

#

these are cached

#

but not

String c = "a".substring(1).concact("a");

#

because it uses new String(chars);

rigid otter May 2, 2021, 8:07 AM

#

Ahh, yeah

dense goblet May 2, 2021, 8:08 AM

#

in short if you want to modify a field of the Player, you need to do Player.xyz = "aaa"

#

doing String s = Player.xyz and then s = "aaa" will not work

lilac dagger May 2, 2021, 8:08 AM

#

but why would you wanna know this?

rigid otter May 2, 2021, 8:09 AM

#

Can I do this to store player in another class?

class User {
  Player player;
  public User(Player player) {
    this.player = player;
  }
}```

dense goblet May 2, 2021, 8:09 AM

#

in English, it would be like saying:
make s point to the memory at Player.xyz
then, make s point to the memory with "aaa" in it
But you want to say:
make Player.xyz point to the memory with "aaa" in it
Which is different

oh, i doubt you have control over that in java

dense goblet May 2, 2021, 8:11 AM

#

yeah you can't do ref or out in Java like you can in C# 😦

#

or C and C++ pointers

lilac dagger May 2, 2021, 8:11 AM

#

it's not worth it imo

#

this is called hardcoding

#

and you're creating stress over changes

rigid otter May 2, 2021, 8:11 AM

#

Haha

dense goblet May 2, 2021, 8:12 AM

#

passing a reference is hardcoding?

lilac dagger May 2, 2021, 8:12 AM

#

no

#

but switch a reference pointer to something else

#

is not a thing in java

rigid otter May 2, 2021, 8:13 AM

#

dense goblet yup

That means when we modifiy player in User class, it will affect to the original Player that hold by somewhat class, right?

lilac dagger May 2, 2021, 8:13 AM

#

we have design patterns to allow us to switch or adapt classes

dense goblet May 2, 2021, 8:13 AM

#

rigid otter That means when we modifiy player in User class, it will affect to the original ...

yes, unless you reassign it
player = new Player() will not affect the original
player.a = b will affect the original

lilac dagger May 2, 2021, 8:13 AM

#

if you want that

Ohh yeeaahh!! I got it!

eternal oxide May 2, 2021, 8:14 AM

#

Player is not guaranteed to be persistent where UUID is.

rigid otter May 2, 2021, 8:14 AM

#

What if I want to copy a player? Makes it duplicate.

eternal oxide May 2, 2021, 8:14 AM

#

The Player object may go stale

lilac dagger May 2, 2021, 8:15 AM

#

that you can @rigid otter

rigid otter May 2, 2021, 8:15 AM

#

eternal oxide Player is not guaranteed to be persistent where UUID is.

Yes, of course

lilac dagger May 2, 2021, 8:15 AM

#

just take the player's EntityPlayer in init in yours

#

oh nvm

#

it can only be 1

rigid otter May 2, 2021, 8:15 AM

#

What?

lilac dagger May 2, 2021, 8:15 AM

#

unless you're modifying entity player to hold 2

#

but then it'll be a lot of work

dense goblet May 2, 2021, 8:16 AM

#

the thing I like pointers for is functions such as bool tryParseInt(int *out)

#

though luckily in Java for this specific scenario there is Integer

lilac dagger May 2, 2021, 8:16 AM

#

so you can have side effects?

#

cool yeah

dense goblet May 2, 2021, 8:17 AM

#

still it feels heavy to need to create a new object just to package multiple values into one return

#

you can pretty much do side effects with lists so it would be good to allow them for all types

rigid otter May 2, 2021, 8:19 AM

#

Ok, but now I got the main point! Thank you Fr33styler#7673 Kaktusz#7790 ElgarL#3528 Buby#2953

lilac dagger May 2, 2021, 8:19 AM

#

also

#

all the pointers

#

are copies

#

the one passed via the function param are copies of the one you used to call that function

#

i think c++ has it too

dense goblet May 2, 2021, 8:21 AM

#

so chaining 5 functions with the same argument creates multiple pointer objects?

lilac dagger May 2, 2021, 8:22 AM

#

int som = 5;
foo(som);

#

foo gets a copy of som

dense goblet May 2, 2021, 8:22 AM

#

ig that makes sense considering you don't want a reassignment to mess with the previous function

lilac dagger May 2, 2021, 8:22 AM

#

exactly

bright yoke May 2, 2021, 8:22 AM

#

have you done a java course before?

lilac dagger May 2, 2021, 8:22 AM

#

same for objects tho

dense goblet May 2, 2021, 8:23 AM

doing one rn ramidzk

#

though its pretty basic

bright yoke May 2, 2021, 8:23 AM

most of my misconceptions about Java are adjusting from other languages

bright yoke May 2, 2021, 8:24 AM

multiple players could be on, how would you handle that

dense goblet May 2, 2021, 8:25 AM

#

doing C# since 2014, then started uni this year which was C, Assembly and now Java which I used briefly before

bright yoke May 2, 2021, 8:25 AM

#

if you've been doing c# this should feel very familiar

dense goblet May 2, 2021, 8:25 AM

yupyup

its an easy switch

@bright yoke and how can i get the Online Players in a variable

dense goblet May 2, 2021, 8:26 AM

and you?

bright yoke May 2, 2021, 8:26 AM

Collection<Player> players = Bukkit.getOnlinePlayers();

but its a collection

okay

how do you want to handle that

#

i want to teleport all online players

#

when they click on a item

bright yoke May 2, 2021, 8:27 AM

ah

#

so you'd want to loop through them all and run a teleport code, right?

near crypt May 2, 2021, 8:27 AM

#

yes...

bright yoke May 2, 2021, 8:27 AM

i dont want to spoonfeed you, try to write something

near crypt May 2, 2021, 8:27 AM

#

okay

bright yoke May 2, 2021, 8:27 AM

#

do you know how to loop through all the players?

near crypt May 2, 2021, 8:28 AM

#

with a loop but idk wich one xD

#

forEach i guess

bright yoke May 2, 2021, 8:28 AM

#

forEach works

near crypt May 2, 2021, 8:28 AM

#

so players.forEach or so?

bright yoke May 2, 2021, 8:28 AM

#

yes

#

for (Player someone : players) {
    // Teleport 'someone'
}
``` this would also work

dense goblet May 2, 2021, 8:28 AM

#

is there a difference between forEach and for(... : ...)?

bright yoke May 2, 2021, 8:29 AM

#

minor speed decrease

#

but 99.9999% of the time the code is slow because of something else, not something as simple as forEach

bright yoke May 2, 2021, 8:30 AM

#

dense goblet is there a difference between forEach and for(... : ...)?

there's also the limits of lambda methods, such as not being able to access non-final variables

dense goblet May 2, 2021, 8:30 AM

#

ah so they're not as powerful as in C#

bright yoke May 2, 2021, 8:30 AM

#

String list = "";

players.forEach(player -> {
    list += player.getName() + ", ";
});
``` this won't work for example

dense goblet May 2, 2021, 8:31 AM

#

but in exchange there's java enums so you win some you lose some
