its there

#

oh wait

#

ive had an idea

#

nope didnt work

#

its in the JAR's root

#

oh

#

i made a typo xD

tardy delta Nov 21, 2021, 1:56 PM

#

does string.replace("a", "b") does anything?

#

instead of str = str.replace()

plucky fog Nov 21, 2021, 1:56 PM

#

string.replace(... where string is your string object

tardy delta Nov 21, 2021, 1:56 PM

#

that doesnt modify string right?

plucky fog Nov 21, 2021, 1:57 PM

#

try it and see

tardy delta Nov 21, 2021, 1:57 PM

#

i tried

quaint mantle Nov 21, 2021, 1:57 PM

#

tardy delta instead of str = str.replace()

Strings are immutable

tardy delta Nov 21, 2021, 1:57 PM

#

uhu

quaint mantle Nov 21, 2021, 1:57 PM

#

so any modifcation methods returns a New string

Is there a way to store an item and its NBT data in a flat file? without NMS

tardy delta Nov 21, 2021, 1:57 PM

#

ah i understand

quaint mantle Nov 21, 2021, 1:58 PM

#

marble granite Is there a way to store an item and its NBT data in a flat file? without NMS

I believe you can use BukkitObjectOutputStream

marble granite Nov 21, 2021, 1:59 PM

#

But that doesnt save NBT does it?

quaint mantle Nov 21, 2021, 1:59 PM

#

it does?

marble granite Nov 21, 2021, 1:59 PM

#

oh ok

tardy delta Nov 21, 2021, 1:59 PM

#

also does .replace() keeps colorcodes?

marble granite Nov 21, 2021, 1:59 PM

#

i was just wondering

plucky fog Nov 21, 2021, 1:59 PM

#

tardy delta also does .replace() keeps colorcodes?

they're part of the string so yes

tardy delta Nov 21, 2021, 1:59 PM

#

thanks

quaint mantle Nov 21, 2021, 2:00 PM

#

tardy delta also does .replace() keeps colorcodes?

yes. Color codes is spigot only thing, java doesnt care about them at all

quaint mantle Nov 21, 2021, 2:00 PM

#

quaint mantle I believe you can use BukkitObjectOutputStream

Tho i've heard that it can break if you change server version

marble granite Nov 21, 2021, 2:00 PM

#

i mean, i can work around that

plucky fog Nov 21, 2021, 2:00 PM

#

so how would i access my file from my plugins Data dir?

marble granite Nov 21, 2021, 2:00 PM

thanks for the info 👍

quaint mantle Nov 21, 2021, 2:01 PM

plucky fog so how would i access my file from my plugins Data dir?

new File(plugin.getDataFolder(), file name)

#

how would i detect when a player makes a grass path?

tardy delta Nov 21, 2021, 2:24 PM

#

there's probably an event for that

brave goblet Nov 21, 2021, 2:26 PM

#

 gui.setItem(0, glassEmpty);
        gui.setItem(1, glassEmpty);
        gui.setItem(2, glassEmpty);
        gui.setItem(3, glassEmpty);
        gui.setItem(4, glassEmpty);
        gui.setItem(5, glassEmpty);
        gui.setItem(6, glassEmpty);
        gui.setItem(6, glassEmpty);
        gui.setItem(7, glassEmpty);
        gui.setItem(8, glassEmpty);
        gui.setItem(9, glassEmpty);```
is there an easier way of doing this? for all slots that dont have a value eg
``` gui.setItem(10, skull("eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvYjIwNjU3ZTI0YjU2ZTFiMmY4ZmMyMTlkYTFkZTc4OGMwYzI0ZjM2Mzg4YjFhNDA5ZDBjZDJkOGRiYTQ0YWEzYiJ9fX0=","Blaze"));```
so i don't have so many lines

its the PlayerInteractEvent

check if the player's holding a hoe

#

and if he rightclicked on grass block

basically the first println is the same as the seconds varuiable

and this is what i get

brave goblet Nov 21, 2021, 2:29 PM

#

tardy delta check if the player's holding a hoe

uh no :/

#

u mean shovel...

#

but ye basically that

wide creek Nov 21, 2021, 2:29 PM

#

I want to check if a player is in a determinate zone. So, i created two vectors (idk if I have to use Vector or Location) and now I don't know if there's a method for check if the player is between the vectors.

brave goblet Nov 21, 2021, 2:29 PM

#

and check if the block clicked on is grass

misty current Nov 21, 2021, 2:29 PM

#

when i use spigot().respawn() on a player in a PlayerDeathEvent, the dead player picks up the items they dropped before getting teleported

Are you on 1.17? If yes, set the immidiateRespawn gamerule to true instead of manually respawning players

misty current Nov 21, 2021, 2:35 PM

#

nah i wish

#

anyways i solved by clearing the drops and respawning them on the ground a tick later

#

is there a better solution tho?

quaint mantle Nov 21, 2021, 2:37 PM

#

misty current anyways i solved by clearing the drops and respawning them on the ground a tick ...

You respawn player after a tick when event fires?

misty current Nov 21, 2021, 2:38 PM

#

then it would show the death screen for a split second

quaint mantle Nov 21, 2021, 2:38 PM

#

Thats the point. When Death event is fired, player is actually not dead. So, by respawning them you cancel his Death -> no loot

Location and if you want to verify whether or not they're looking at them, dot product between product vector and their direction

#

targetLocation.toVector().subtract(playerLocation.toVector()).dot(player.getDirection()) should give you a value between 1 and -1, where 1 is looking directly at them

you know what I mean.
you have a GUI, it has "buttons" (which are actually just itemstacks) that performs actions on click, you check the X and Y in that gui for the specific items you need actions to occur on clicking, and you cancel the event so that it doesn't pick up the item (but the code before the cancel still executes if it matches your X/Y checks)

brave goblet Nov 21, 2021, 3:17 PM

Player#openInventory() will return the InventoryView and the InventoryView is fetchable in an InventoryClickEvent

unless, well

you wanted to make cancel a default method

otherwise it violates SAM requirements

tardy delta Nov 21, 2021, 3:25 PM

what's SAM? 🥺

lavish hemlock Nov 21, 2021, 3:25 PM

#

single abstract method

tardy delta Nov 21, 2021, 3:26 PM

#

i already know SRP but yeah

lavish hemlock Nov 21, 2021, 3:26 PM

#

the requirements for an interface to be able to be used as a lambda

tardy delta Nov 21, 2021, 3:26 PM

#

aha

lavish hemlock Nov 21, 2021, 3:26 PM

#

AKA a functional interface

tardy delta Nov 21, 2021, 3:26 PM

#

never understood the FunctionalInterface annotation

lavish hemlock Nov 21, 2021, 3:26 PM

#

an interface, if declared with @FunctionalInterface, must only have 1 abstract method

#

meaning one without a body, of course

#

that's cuz that method is used to call the lambda belonging to the interface

tardy delta Nov 21, 2021, 3:27 PM

#

but if you just make an interface with one abstract method it also works

lavish hemlock Nov 21, 2021, 3:27 PM

#

and it wouldn't make sense to have more than one abstract method, as there's no syntactical representation for it

tardy delta Nov 21, 2021, 3:27 PM

#

hmm

lavish hemlock Nov 21, 2021, 3:28 PM

#

tardy delta but if you just make an interface with one abstract method it also works

ye, but @FunctionalInterface is used to enforce that as well as state that it is designed as a functional interface

#

without the annotation, compilers won't error if you violate the SAM contract

#

Java's got a lot of "warn/error if I have this and I do something bad" annotations

#

e.g. @Override, @SafeVarargs, @FunctionalInterface

brave goblet Nov 21, 2021, 3:28 PM

Thats helpful

lavish hemlock Nov 21, 2021, 3:34 PM

methods are part of the classes they're declared in and not the instances, so it makes no real difference in performance

Well Minecraft's server is running on the same thread as your Server, so when you run while (true) on that thread, it pauses the thread to perform actions indefinitely.

So i need to remoeve the while true

#

How i will wait for the socket connection if i remove the while?

lavish hemlock Nov 21, 2021, 4:00 PM

No, you just need to launch your Server on a separate thread.

I thought a SocketChannel was for communicating on a socket?

CompletableFuture might actually create a new thread

Socket is sort of an io device

#

socket channel is the non blocking variant

lavish hemlock Nov 21, 2021, 4:05 PM

It's part of the NIO Channel API so, I assumed it was a replacement for using a OutputStream/InputStream on a Socket.

Well

When you've done

A try/catch around your method that declares a lambda

#

And then you have to put another try/catch in your lambda

And, if you have nested lambdas, even more try/catches

You kinda give up on living.

By the way this doesn't touch on an Event class, but for that you'd basically just create a class that contains all the data the listener needs for that event, so not particularly difficult.

young knoll Nov 21, 2021, 7:13 PM

Proper encapsulation is good

tardy delta whats the point of making a field private if you can access it using reflections

Reflections are hellla lot slower than simple reference read access

#

That's why I prefer PacketDataSerializers for Packets, they allow me to work without reflection overhead

young knoll Nov 21, 2021, 7:14 PM

#

Honestly they aren’t that slow those days

#

Especially if you cache the fields and methods

mortal hare Nov 21, 2021, 7:15 PM

#

yea but still, if there's a way to not use them, exploit that way

#

unless its heavier to compute ofc

#

also by not using reflections you avoid all utility class mess with try catch blocks

grave kite Nov 21, 2021, 7:17 PM

#

there is probably one more way, but I don't want to make changes in spigot.jar

the problem is, I don't know how to cast that Field thing

When in creative mode the server basically just lets you do whatever with your inventory

#

You can still kind of detect it though

#

I have done it before

Let me dig up the code

#

Basically, just check for when InventoryCreativeEvent is fired

#

Check if it's a hotbar slot and their cursor is empty

#

Then check if the block they selected is the same as the one they are looking at

native bloom Nov 21, 2021, 9:53 PM

Probably a dumb question, but does inventorycreativeevent fire in gms?

native bloom Probably a dumb question, but does inventorycreativeevent fire in gms?

No

native bloom Nov 21, 2021, 9:53 PM

#

rip... the primary intended use case for my attempt to detect it is survival

#

Basically trying to find a way a player can interact with a block without right clicking it or left clicking it (both of which are already used for something else)

waxen plinth Nov 21, 2021, 9:54 PM

#

Hmm

#

I don't think that fires any event

#

Well, it would actually

#

The event for changing their hotbar slot

#

I guess the best you could do is see if they change their selected hotbar slot to be holding the same block as what they are looking at

#

That would be even less reliable than the creative mode one though

native bloom Nov 21, 2021, 9:55 PM

hmm

Are these three also client side?
