Ok guys wait everyone, I am currently on adding the open inventories to a list and removing them from that list if they are closed, but somehow I keep running into this:
Cannot invoke "java.util.List.isEmpty()" because "this.inventoryList" is null

quaint mantle Aug 25, 2021, 12:52 AM

#

that breaches the api, instead you can create a custom holder (non-api)

#

although InventoryHolder works perfectly its not intended to be used that way

silver shuttle Aug 25, 2021, 12:52 AM

#

with what value

#

public List<Inventory> inventoryList = new ArrayList<>();?

#

public class InventoryCloser implements Listener

use a set, not a list

#

HashSet to be exact

silver shuttle Aug 25, 2021, 12:53 AM

what is the advantage of using a set in that case?

quaint mantle Aug 25, 2021, 12:53 AM

#

silver shuttle what is the advantage of using a set in that case?

sets are way faster and since you arent caring for the order, you should use it

silver shuttle Aug 25, 2021, 12:54 AM

#

okayy

quaint mantle Aug 25, 2021, 12:54 AM

#

how?

silver shuttle Aug 25, 2021, 12:54 AM

#

fsr now the events dont fire anymore at all

quaint mantle Aug 25, 2021, 12:54 AM

@sinful egret a custom inventory holder, thats not inside the api

expandable

quaint mantle Aug 25, 2021, 12:55 AM

silver shuttle fsr now the events dont fire anymore at all

send code where you register them

silver shuttle Aug 25, 2021, 12:56 AM

#

public List<Inventory> inventoryList = new ArrayList<>();

I am opening the inventory called inv and adding it to the list

inventoryList.add(inv);

This event doesnt fire at all

    public void onInventoryClick(final InventoryClickEvent e) {
        if(inventoryList.isEmpty()) return;
        if((inventoryList.contains(e.getInventory()))) {

I am so confused, I have the "InventoryList" as a public Set, when I open the Inventory and print the Set, it contains the correct inventory data, but when I then try to interact with it, the list is empty even though the closeEvent is not called

pliant flame ok I'm a bit confused now. People are telling me /restart doesn't mess up plugin...

its 50/50. plugins either hold mass amounts of data or dont. it should be handled correctly, but in most plugins (including my own) its overlooked and the smallest data gets leaked

pliant flame Aug 25, 2021, 1:17 AM

I thought /restart just did basically the same thing as /stop, and that /reload was the only bad thing SC_ZERO_THINK

silver shuttle Aug 25, 2021, 1:18 AM

quaint mantle Aug 25, 2021, 1:18 AM

stop stops the server and restart runs the startup file specified

reload any plugin individually

like /reload for singular plugins and their dependencies

very useful and hard to break

quaint mantle Aug 25, 2021, 1:19 AM

silver shuttle reload any plugin individually

deadass sounds like an individual /reload command

silver shuttle Aug 25, 2021, 1:19 AM

just try the plugin, you'll love it

quaint mantle Aug 25, 2021, 1:19 AM

#

no

silver shuttle Aug 25, 2021, 1:19 AM

#

you can just drop your new plugin in and overwrite your old version, it'll automatically reload it from the new file

#

if you're using linux atleast ^^

You are using armorstands correct?

They should definitely be removed

sorry if this is a dumb question but is there any way to get the amt of ticks left inside of the method? I want to have like a 30 miinute/15 minute warning, and a command that lets players see how much time is left.

            public void run() {

            }
        }.runTaskTimer(this, 0L, 72000L);```

Does anyone here have experience with registering placeholders for PlaceholderAPI? I'm trying to register a placeholder but it doesn't seem to work. Either that or there's something wrong with Featherboard that doesn't recognize it, but this is my class for the placeholder %islandalias%. I am calling the register method of PlaceholderExpansion in the onEnable() method

stark marlin Aug 25, 2021, 5:30 AM

stark marlin Does anyone here have experience with registering placeholders for PlaceholderAP...

The issue might be that I have load: STARTUP in my plugin.yml and therefor the plugin seems to ignore that PlaceholderAPI is a softdependency, it still loads my plugin before PlaceholderAPI, and therefor I have to delay registering the placeholder with 1 tick so that the PlaceholderAPI plugin is enabled when doing it, but then Featherboard seems to initialize before the placeholder is registered instead. Any idea how I could get around this? 🤔

young knoll Aug 25, 2021, 5:34 AM

#

Does it load or enable it before placeholder API

#

Or both

stark marlin Aug 25, 2021, 5:36 AM

#

Not sure, I didn't know there was a difference. Is it possible to check that?

young knoll Aug 25, 2021, 5:36 AM

#

Watch the messages in console

stark marlin Aug 25, 2021, 5:37 AM

#

Yeah right, PlaceholderAPI is loaded before my plugin

#

But my plugin is enabled before though

young knoll Aug 25, 2021, 5:38 AM

#

Huh

#

I would have imagined the opposite

stark marlin Aug 25, 2021, 5:40 AM

#

Looks that way. It loads PlaceholderAPI, then my plugin, and then it enables my plugin and then enables PlaceholderAPI and Featherboard and lastly (delayed by one tick) it registers my placeholder so perhaps Featherboard ignores it for that reason

ok sure

Im currently in the process of making a audioclient for minecraft.
I want to create speakers that pan from left to right depending on how the player rotates his head.

I currenty have this code, which works to a ceartain degree but it flips the value when im behind a block, and it only works for a certain radius:

public double getAudioLRValue(Player p, Location target){
Vector look = p.getLocation().getDirection().normalize();

Location head = p.getLocation().add(0, p.getEyeHeight(), 0);

Vector direction = head.subtract(target).toVector().normalize();

Vector cp = direction.crossProduct(look);
return cp.normalize().getZ();
}

How do I check if a location is to the left or right of a players head?

Yes

quaint mantle Aug 25, 2021, 8:16 AM

#

why not cancel the event

#

and then apply a new effect copying the old effects attributes

#

i know it would loop infinitely but it looks like you can tag the reason it was applied

#

maybe use that as a guard clause?

#

other than that,

    public Map<String, Object> serialize() {
        return ImmutableMap.builder().put("effect", this.type.getId()).put("duration", this.duration).put("amplifier", this.amplifier).put("ambient", this.ambient).put("has-particles", this.particles).put("has-icon", this.icon).build();
    }```
this is in PotionEffect.class

can probably play around with nms if you want to go down that rabbit hole

could make your own custom event

cancel the EntityPotionEvent, parse in the potion data and then you can adjust it as you'd like

probably simplest way to do it

Looks like FAWE is your problem. Try installing an older version. Same goes for ProtocolLib.

Did you check if a file was created after the command?

i created it before i ran the command

lost matrix Aug 25, 2021, 8:45 AM

Because if you pipe then you dont see stdout. It will be written to the file instead.

#

And you dont need to create it.

yes t creates one

lost matrix Aug 25, 2021, 8:48 AM

did you check the right location? Call ls from the location you used the command from.
Using the pipe operator should work unless the application does not run in the same terminal.

calm whale I would like to prevent block (flowers) from being destroyed by fireball explos...

The BlockExplodeEvent should work if the flower is directly destroyed by the explosion. Just not if the explosion destroys a block that has a flower on it.

grim ice Aug 25, 2021, 10:41 AM

just check if blocks destroyed have flowers above them

it is a fireball explosion on end stone block

the block resistance is too strong

I mean you also have to listen for the EntityExplodeEvent as this one is triggered by creapers and fireballs.

BlockExplode only covers beds.

Im trying to teleport an entity when it is far away from players however i am having an issue where it is not getting teleported when it is that far away (assuming cause it is in unloaded chunks)

im trying to get this to work for both 1.8 and 1.17 so unfortunately i dont have the plugin chunk tickets Sadge

also - the method to cancel chunk unloads has been removed since 1.8 so i cannot use that... any ideas

eternal night Aug 25, 2021, 11:25 AM

#

Run the same teleportation logic on chunk unload ?

#

To teleport the entity before it is unloaded

opal juniper Aug 25, 2021, 11:26 AM

#

yeah... how do the methods like Chunk#load work? does it stay loaded for a while or does it immediately unload when mc sees there is no point of it being loaded?

eternal night Aug 25, 2021, 11:26 AM

#

Pretty much

opal juniper Aug 25, 2021, 11:29 AM

#

ig the other way to do it is to despawn the entity when it is about to go into empty chunks? that way i could wait until it is in loaded chunks again and respawn it?

for context i have a list of locations i am iterating thru and teleporting them along

#

i also avoid loading a tonne of chunks

grim ice Aug 25, 2021, 11:40 AM

#

String resultMessage = deliveryMessage;
if(deliveryMessage.contains("@")) {
resultMessage = deliveryMessage.replace('@', ' ');

is this fine

i use result mesage later on

hybrid spoke Aug 25, 2021, 11:49 AM

you can still get the location and update the entities location without actually teleporting it.

im new to plugin development, how would i make a command only usable once? like once a player uses the command, they can not use it ever again

eternal night Aug 25, 2021, 12:24 PM

#

you'd store their uuid in a form of persistency (e.g. a database) and validate that, when they run the command, their uuid does not exist in the persistency layer yet

#

another alternative, maybe better for you as you are new to plugin development, might be the PDC

#

or just writing it into a config file

basically allows you to write data onto the player object directly that persists over a server restart

#

hence you could simply store a byte or something on the player and check agains tthat

grim ice Aug 25, 2021, 1:02 PM

#

yes

#

thats only in minecraft 1,13+ tho

#

u gotta use nbt if ur under that

#

which is also ez

#

@lofty laurel LOL

#

I HAVE ANOTHER IDEA

#

give a player the permission to use it when he joins the server and hasnt played before

#

then when he runs it his permission get removed

#

thats the best way to do it imo

#

and simplest

lofty laurel Aug 25, 2021, 1:04 PM

yeah thats probably better for me bc i've tried like 5 times and just getting an internal error when running the command lol

like PEX

its easier to do with persistent data containers

u cant make ur plugin cross version compatible with pdc

you would have to recode the whole thing

Usernames are changeable. UUID's are not. This means if you are storing data using player names, and that player changes their name, they'll lose that data.

#

firstempty in which direction is that looking for a slot? 🥺

rigid hazel Aug 25, 2021, 2:03 PM

#

tardy delta firstempty in which direction is that looking for a slot? 🥺

From top left

severe marsh Aug 25, 2021, 2:03 PM

#

Should I put it in onDisable?

#

or it doesn't matter

rigid hazel Aug 25, 2021, 2:03 PM

#

severe marsh Should I put it in `onDisable`?

No. Everytime after editing the config

severe marsh Aug 25, 2021, 2:03 PM

#

Alright thanks

tardy delta Aug 25, 2021, 2:04 PM

#

i just wanted to let the distance between the target slot and the slot where its finnaly placed as small as possible

#

but yea if thats isnt possible : (

rigid hazel Aug 25, 2021, 2:05 PM

#

tardy delta but yea if thats isnt possible : (

It is possible. Just use math if you want it that way

tardy delta Aug 25, 2021, 2:05 PM

#

rigid hazel Aug 25, 2021, 2:05 PM

#

tardy delta Aug 25, 2021, 2:05 PM

#

rigid hazel Aug 25, 2021, 2:06 PM

#

severe marsh `getConfig().save(fileHere);` how do I put file?

Did you save the file in a instance?

severe marsh Aug 25, 2021, 2:06 PM

#

#

rigid hazel Aug 25, 2021, 2:06 PM

tardy delta i just wanted to let the distance between the target slot and the slot where its...

The code I posted above does exactly that

#

Its gets the first empty slot of the inventory

#

if its -1 there are no empty slots

tardy delta Aug 25, 2021, 2:07 PM

#

yea but it checks for empty slots beginning from the top left

young knoll Aug 25, 2021, 2:07 PM

#

They want it as close to the target slot as possible

stone sinew Aug 25, 2021, 2:07 PM

#

tardy delta yea but it checks for empty slots beginning from the top left

Say you put it at slot 1 right??? but that slot contains an item.. but slot 2 is empty... firstEmpty will give you slot 2

tardy delta Aug 25, 2021, 2:08 PM

#

oh really

stone sinew Aug 25, 2021, 2:08 PM

#

tardy delta oh really

yes

young knoll Aug 25, 2021, 2:08 PM

#

Yes but if you want to put it at slot 10 and it’s full, first empty would still find slot 2 first

tardy delta Aug 25, 2021, 2:08 PM

#

slot 0, 1, 2 etc are hotbar right?

#

or am i wrong

stone sinew Aug 25, 2021, 2:09 PM

#

tardy delta slot 0, 1, 2 etc are hotbar right?

In a player inventory yes

tardy delta Aug 25, 2021, 2:09 PM

#

oh ok

stone sinew Aug 25, 2021, 2:09 PM

#

@young knoll is right about firstEmpty though so keep that in mind

young knoll Aug 25, 2021, 2:11 PM

#

If you want it close to a specific slot you can just use a loop and check if slot +- loop value is empty

tardy delta Aug 25, 2021, 2:13 PM

#

bruh

#

i thought i could use firstempty and now its wrong

young knoll Aug 25, 2021, 2:13 PM

#

First empty will find the first empty slot

#

Which isn’t necessarily the closest empty slot

hello! How can I send a custom sound to a player?

#

I'm currently using this ENUM: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Sound.html

Sound (Spigot-API 1.17.1-R0.1-SNAPSHOT API)

declaration: package: org.bukkit, enum: Sound

#

but some users add new sounds via a resourcepack

paper viper Aug 25, 2021, 2:18 PM

#

you cant use that enum for playing custom sound

#

you have to use the playSound method with a String

#

and for the string put the custom sound name

#

from the resourcepack

rigid hazel Aug 25, 2021, 2:20 PM

#

rigid hazel Same problem, but now with the gold blocks. I can't break them, until the chunk ...

Hello. Can someone help?

paper viper Aug 25, 2021, 2:21 PM

#

Don't really have the time to look at the code closely, but that's not how you use adventure properly

#

you never use color codes in Component.text("")

#

instead, use NamedTextColor
