Imagine.

[lean gull]

but it's 6

[lyric oar]

hey, it's me again, now i would like to make a permission plugin for my server but i don't know how to deny all permissions to a player. Is there a way to do that?

[quaint mantle]

Learn to read numbers before asking please.

[lean gull]

it's 8 but without the bold &l and &x it's 6

[quaint mantle]

Then it would probably me to learn to read numbers before answering question…

Tho it is kinda hard to see those characters in app discord…

[lean gull]

don't make excuses, you were toxic for no reason whatsoever and it ended up you were wrong

now can i please get some help from someone who won't judge me?

[quaint mantle]

Toxic?

[lean gull]

that's toxic

[quaint mantle]

Uhhh ok…

Lol

[slim kernel]

my start.bat looks like this tho. Do I just change the %JAVA_PARAMETERS% to %JAVA_8% then?

@echo off

call settings.bat

:start_server
echo Starting SevTech Ages of the Sky Server...
java -server -Xms%MIN_RAM% -Xmx%MAX_RAM% %JAVA_PARAMETERS% -jar %SERVER_JAR% nogui
pause
exit /B

goto start_server

[quaint mantle]

Change java-> %JAVA_8%

[slim kernel]

Thank you so much

[quaint mantle]

[slim kernel]

@lost matrix thank you so much for always helping me aswell

[lean gull]

how do i get the amount of values in a config file?

like a FileConfiguration type thing

[quaint mantle]

getKeys(false)

.size

(true) would return all keys for the given section and all of their subsections as well

[tardy delta]

can i compare world instances or do i need to check for the name?

[quaint mantle]

So if you just want the base section you use (false)

[quaint mantle]

I’ve never really compared worlds any other way than by their name, considering you can’t have two worlds with the same name

Why don’t you test it out 🤔

[tardy delta]

yea true but i was just wondering

[quaint mantle]

Yea not sure about that one

[tardy delta]

i'm not going to compile and run it every time 😂

[quaint mantle]

Lol

[silver shuttle]

gradle > maven == true ?

[tardy delta]

gradle brr

[silver shuttle]

good, glad Ive been using Maven all along then

[lean gull]

how do i know if i use maven or gradle

[tardy delta]

probably maven

[lean gull]

maven is the buildtools one right?

[tardy delta]

uhh

that doesnt matter i guess

🤔

[ivory sleet]

Yes

Pretty much

[ivory sleet]

Yeah they’re cached, no reason not to

[lean gull]

is that IntelliJ?

[tardy delta]

yesh

[lean gull]

wohh how u make it look liek dat

[tardy delta]

uhh a theme i guess

[tight hedge]

Can someone help me? How do i make a holographic display that displays the balance of the baltop, idk what placeholders

plz help out boys need this asap

[jade perch]

Paying someone to do it would probably be the fastest

[tight hedge]

sort of like this

[bold plank]

is setmarker a paper method or does spigot have it too?

[tight hedge]

I got this far but i dont know how to make it auto update.

[jade perch]

spigot has it

[tight hedge]

If i have a command that runs every 15 second to auto update the entire holograph would that lag the server?

[bold plank]

sweeeeet

[unique meteor]

spigot

[jade perch]

no

[unique meteor]

and its the other way around, if spigot have it, paper would have it too.

[unique meteor]

depends on what you are doing

[tardy delta]

you might be doing it async if you have alot of scoreboards

[tight hedge]

Whats that?

[bold plank]

yeah, anyways ty

[tight hedge]

is there a difference if i run it every 15sec or 1 sec (performance wise)

[jade perch]

Yes

[unique meteor]

depends on what you are doing

[jade perch]

it will run 15 times

[tight hedge]

updating placeholders

I've got to the placeholder part on display but i dont know how to make it updatre

[unique meteor]

since you will only notice a peak of performance if your operation comes over 20ms, i wouldn't think so

unless you are accessing some DB or files

[tardy delta]

does that else has a purpose?

[tight hedge]

I will use a plugin that runs commands and just redoes the entire command aka /hd setline baltop 1 %baltop_1_player%

[tardy delta]

as i do a return

[silver shuttle]

            Player shooter = killEvent.getKiller();
            UUID shooterUUID = shooter.getUniqueId();
            if(playerKills.containsKey(shooterUUID)) {
                int val = playerKills.get(shooterUUID);
                int time = val % 100;
                val = val - time;
                playerKills.put(shooterUUID, val + 110);
            }
            else {
                playerKills.put(shooterUUID, 110);
            }
            if(!(playerStreaks.containsKey(shooter.getUniqueId()))) {
                scheduler.runTaskTimer(myPlugin, task -> {
                    playerStreaks.put(shooterUUID, task.getTaskId());
                    playerKills.put(shooterUUID, (playerKills.get(shooterUUID) - 1));
                    if(playerKills.get(shooterUUID) % 100 == 0) {
                        task.cancel();
                        playerKills.remove(shooterUUID);
                        playerStreaks.remove(shooterUUID);
                    }
                }, 20L, 20L);
            }
            int kills = (playerKills.get(shooterUUID) - (playerKills.get(shooterUUID) % 100)) / 100;
            final char killMarker;
            if(kills > 10) {
                kills = 10;
            }
            killMarker = (char) ('\ue100' + kills - 1);
            String killSound = "killmarker" + kills;
            shooter.sendTitle("" + killMarker, "", 0, 10 + (kills * 4), 10);
            shooter.playSound(shooter.getLocation(), killSound, 1, 1);

Okay so this event gets called whenever a player kills another entity.
It adds the killer's uuid to a map and assigns a score (100 for each kill, 10 points as timer)
Then it starts a streak timer which then removes 1 point per second from each players score
This task gets cancelled once the score is divisable by 100 and rest is 0
However, the line
playerKills.put(shooterUUID, (playerKills.get(shooterUUID) - 1));
returns an exception sometimes, saying that the return value is null.
Any ideas why that might happen or how to fix that?

(It is not really if a player kills any entity, it is related to CrackShot, killing entities is just for reference as it is the same effect)

[jade perch]

Weird way to do that

[silver shuttle]

What's a better way

I tried to think of one yet I didnt have any ideas

[silver shuttle]

I need that for killstreaks and different sounds and effects for each kill

[last ledge]

I am trying to use Custom Enchanments for ItemStack items(Armors), but when i try to run it it says : Caused by: java.lang.IllegalArgumentException: Enchantment level is either too low or too high (given 3, bounds are 1 to 2)

[jade perch]

You don't need two different hashmaps

[last ledge]

how do i use custom enchanments

like unbreaking 10

in itemstack?

[silver shuttle]

one has the score, one has the task id's so I can cancel them

[jade perch]

Yeah you can just make an object that tracks both

[silver shuttle]

and so I know which player already has a clock to reduce the tasks

[silver shuttle]

which object could have a UUID, Integer and Integer?

[fiery inlet]

Anyone know how to make piglins dance the victory dance they do when killing a hog??

[jade perch]

make a hashmap with the uuid key, and make an object that stores two integers

[tardy delta]

are you lacking the level restriction?

[jade perch]

then you can have HashMap<UUID, yourRandomTwoIntegerObject>

[silver shuttle]

ok couldve done that but it doesnt fix the problem

[last ledge]

yes, i cant use enchanment levels like 10, 15

[tardy delta]

normally i had something like this

[fiery inlet]

does no one know how to make piglin dance

[last ledge]

can you send me that project? imma have a look

[silver shuttle]

obviously not

[tardy delta]

if set to false it would normally accept higher levels

[jade perch]

If you're getting a null exception try to figure out why that's happening

[silver shuttle]

I'm gonna rewrite it with that, one sec

[silver shuttle]

I really tried

[jade perch]

might have something to do with how you're removing the uuid from the hashmap

[silver shuttle]

the problem is: if it gets removed, the task also gets immediately cancelled

ooooh wait

it coul dbe

no wait

doesnt make sense

[jade perch]

Would be much easier to just make a hashmap with a tracker object

instead of using hashmap.remove

then you wouldn't have to worry about it

[silver shuttle]

mhm

any better overall solution for this?

[jade perch]

Yes, make the tracker object like I said before

[silver shuttle]

no like overall

[tight hedge]

is there a placeholder for economy top with vault?

[jade perch]

Not off the top of my head

[tight hedge]

could anyone help me out please because im having alot of issues with it.

[silver shuttle]

I figured out the problem

since the task has a starting delay before it adds it to the streaks map

it might be starting 2 tasks

which causes the problems

so i need to set it to 11 seconds and set the delay to 0

let me try this again

[bold plank]

Hey guys I'm trying to make a custom terrain generator, but biome generation appears fragmented, could someone help me out?

Is there any way to check if a player already sees a title?

[stone sinew]

Maybe check outgoing packets to player

[silver shuttle]

there are no packets sent after the initial

[opaque panther]

i tried to make gui in spigot but console says initializing legacy material

spigot version is 1.17.1

[fiery inlet]

send code

[karmic mural]

?paste

[undone axle]

https://paste.md-5.net/

[opaque panther]

and api-version is 1.17

[tardy delta]

does HashMap#remove(Object key, Object value) tries to remove as much as possible or does it only removes it the map contains both?

[lost matrix]

If its initializing legacy material then some plugin does use an old or no api version

[opaque panther]

no no i only have my plugin

[visual tide]

have you got api-version: 1.17 in your plugin.yml?

[opaque panther]

yea

[opaque panther]

oh

[karmic mural]

?paste

[undone axle]

https://paste.md-5.net/

[opaque panther]

i removed it and tried to but still didnt work @lost matrix

[winged hinge]

HashMap.remove() removes the attachment which i added from the hasMap, this do nothing with the effective permissions

[lost matrix]

Look inside the compiled jar (inside your plugins folder) and make sure your plugin.yml is in there

[tardy delta]

what

i wasn't responding to that

[opaque panther]

plugin.yml is there because all the commands in it are working

[winged hinge]

oh sry xD

[lost matrix]

If you looked inside your jar and the api-version is set then legacy materials wont be loaded

[opaque panther]

wait i checked my jar file and there is plugin.xml

thats it?

[hasty prawn]

Only 1 or 0 can exist, so it removes it if it does and nothing if it doesnt

[tardy delta]

uhh what

ah got it

[opaque panther]

it is still saying initializing legacy even tho the api version is 1.17

anyone any idea?

?

this is the message in console

[fallow merlin]

Kind of unrelated to development; is there a mod that allows me to see mob pathfinder goals?

similar to bedrock developer edition

[tardy delta]

if i only create one instance of a class, is static useful?

[upper vale]

As in a singleton pattern?

[patent quarry]

Hey, someone know if I can avoid the name of the armorstand to turn black ?

[hasty prawn]

Make it a Marker and put the armorstand above the block

[patent quarry]

I will try that ty

[patent quarry]

By above the block wdym ?

[onyx shale]

afaik its a rather common problem

try setting the armor stand on fire

[lost matrix]

This happens if the physical part of an armorstand intersects with a Block.
One solution is to simply disable the whole body of the armorstand. This is done
by making it a marker.

[patent quarry]

Ty it works !

[worldly ingot]

The only one I found is here but it doesn't look to be updated past 1.15.x
https://www.curseforge.com/minecraft/mc-mods/debug-renderers

Otherwise, if you're capable of Forge (or Fabric) modding, you can definitely enable those renderers yourself. They're built into the client, they're just not activated

[fallow merlin]

where would I start with doing this??

[tardy delta]

can't i use someString.replace() instead of someString = someString.replace()?

[lost matrix]

Strings are immutable. This means every time you want to change a String you need to create a completely new Object which includes the changes

[tardy delta]

ah

the char[] is final smh

[waxen plinth]

StringBuilder is mutable

[quaint mantle]

i have a question about substring

for example

skull-blablabla

if i want the blablabla

should the startindex be 6 ?

[lost matrix]

Program it position agnostic

  public String getStringAfter(String line, char delim) {
    return line.substring(line.indexOf(delim));
  }

This will return the String which comes after the first delimiter char

Doesnt matter where its located at

[quaint mantle]

if the char delim is -

will it get for example blablabla

[ivory sleet]

I mean you shouldn’t use static just because it happens you only need one instance of a class.

[lost matrix]

Uhm. I think it will get "-blablabla"

So then

  public String getStringAfter(String line, char delim) {
    return line.substring(line.indexOf(delim) + 1);
  }

[toxic mesa]

is there an easy way to figure out where lost connection: Internal Exception: java.lang.IllegalStateException: Asynchronous getNearbyEntities! is coming from?
I legit can't figure out where it's coming from as I use a util function to fetch nearby entities and it worked and now it doesn't?

[lost matrix]

Sure. Some bob calls spigot methods async.

Show the places where you call it

[toxic mesa]

there's a shit load of em

just go through them all and debug one by one or smth?

[lost matrix]

Why are there so many places where this method is called? That sounds like a big design problem.
Do you call this method in an event that starts with "Async"?

Or in a task that was started using ".runTaskAsynchronously()"?

[ancient plank]

some bob square pants

[toxic mesa]

am busy reworking old messed up plugin, only events used don't use getNearbyEntities, uses packets, no clue if that effects anything
Might be easier to just start from scratch lmfao

[lost matrix]

Yeah scrap that

[rancid pine]

How would I change mob textures in my plug-in, I want to make the creeper texture blue

Instead of green

[lost matrix]

You cant unless you distribute a resource pack to the clients

[rancid pine]

Oh ok

Would there be a way to make mobs huge

[lost matrix]

With a forge mod probably

[fading lake]

giant zombie exists, otherwise mods

[young knoll]

I wish Mojang let us scale all mobs

Like we can with slimes and phantoms

[fading lake]

you can do it with phantoms?

[lost matrix]

And add new Blocks, Items and GUIs

[young knoll]

Yeah phantoms have a size tag

Mojang never used it

[fading lake]

which ones are phantoms again? Im a 1.8 user

[young knoll]

The annoying ones that spawn if you don’t sleep

[rugged topaz]

placed a world folder in my server dir, renamed it, now trying to teleport to it with a location and a Bukkit.getWorld("world_name") and it returns a NullPointerException, what's the cause?

[timid valley]

hello there, i want to play a sound to a player from this event. I would normally use Player.playSound(...) but I'm not sure how to get the player from this event, or if theres a better way to do so.

@EventHandler
    public void onEntityDamageByEntity(EntityDamageByEntityEvent e) {
        if (e.getEntity().getType() == EntityType.PLAYER && e.getDamager().getType() == EntityType.PLAYER) {
            e.getEntity().sendMessage("");
            // Play sound to entity?
            e.setCancelled(true);
        }
    }

[lost matrix]

You need to load the world before you can use it

[rugged topaz]

and what would be the method for that?

[lost matrix]

With an instanceof check and casting

[eternal oxide]

if (e.getDamager() instanceof Player && e.getEntity() instanceof Player player) {
player.sendMessage...```

[lost matrix]

    Bukkit.createWorld(WorldCreator.name("world_name"));

[rugged topaz]

got it thanks

[timid valley]

Im pretty new to Java but to cast I would do something like Player player = (Player) e.getEntity() correct?

Also is it better to use instanceof instead of checking the type with Entity.getType()?

[eternal oxide]

in some instances the object you get may be null. in which case you will throw an error, instanceof will not

[timid valley]

Ohh okay, gotcha. thank you :)

[lost matrix]

One sollutuion:

  @EventHandler
  public void onDamage(final EntityDamageByEntityEvent event) {
    final Entity attacker = event.getDamager();
    final Entity defender = event.getEntity();

    if (!(attacker instanceof Player attackingPlayer)) {
      return;
    }

    if (!(defender instanceof Player defendingPlayer)) {
      return;
    }

    attackingPlayer.playSound(...);
    defendingPlayer.playSound(...);
  }

Or this:

  @EventHandler
  public void onDamage(final EntityDamageByEntityEvent event) {
    final Entity attacker = event.getDamager();
    final Entity defender = event.getEntity();

    if (!(attacker instanceof Player) || !(defender instanceof Player)) {
      return;
    }
    
    Player attackingPlayer = (Player) attacker;
    Player defendingPlayer = (Player) defender;
    attackingPlayer.playSound(...);
    defendingPlayer.playSound(...);
  }

[eternal oxide]

top one is cleaner and uses java 16 methods.

[lost matrix]

This gets me thinking if there is a functional way of calling instanceof and casting...

[buoyant viper]

((Player) e.getEntity()).playSound ?

ah it was already answered

nvm

but yeah u just gotta cast it

[lost matrix]

*Dont forget to check the instanceof

[buoyant viper]

he pretty much does by calling getType and making sure its Player

[opal juniper]

if (entity instanceof Player player) {}

idk what you meant lol

[buoyant viper]

cries in still using java 11

[opal juniper]

oh

[buoyant viper]

still waiting for graalvm to have a j16 on scoop.sh

top 10 reasons i shouldve switched to linux when i built my pc

less waiting most of the time 😔

[lost matrix]

  @EventHandler
  public void onDamage(final EntityDamageByEntityEvent event) {
    IsInstance.of(Player.class, event.getEntity()).ifPresent(player -> player.playSound(...))
  }

  public static class IsInstance {
    public static <T> Optional<T> of(final Class<T> clazz, final Object obj) {
      return Optional.ofNullable(obj != null && clazz.equals(obj.getClass()) ? clazz.cast(obj) : null);
    }
  }

😄

[lost matrix]

Isnt 17 the next lts version? I dont think graal will release for java 16

[buoyant viper]

i think so, but graal for java 16 is out, just not available using scoop PM

could probably find it with winget but

or choco

[lost matrix]

Just build a docker with native linux code ^^
The windows kernel sim of linux is quite good

[buoyant viper]

wsl?

[lost matrix]

yeah WSL 2

ill just use linux then 😼😎

[buoyant viper]

wouldnt using Class#isAssignableFrom be more suitable than .equals? just incase obj isnt the exact class of clazz but is still an extension of it

[lost matrix]

true

[young knoll]

Gosh we get the fancy new inline casting with instanceof all y'all still love your lambdas :p

[buoyant viper]

ofc

theyre fun

[young knoll]

How many chained lambdas is too many chained lambdas

[buoyant viper]

no such thing

[lost matrix]

No limit

-> go brrr

[young knoll]

Code an entire plugin with Lambdas

[buoyant viper]

rewrite command system to use brigadier

[young knoll]

buildergadier

[lost matrix]

  @EventHandler
  public void onDamage(final EntityDamageByEntityEvent event) {
    Optional.of(event.getEntity()).stream()
        .filter(e -> e instanceof Player)
        .map(Player.class::cast)
        .forEach(player -> player.playSound(...));
  }

[buoyant viper]

is that overhead for making a collection ?

[final star]

hello guys I'm trying to integrate minecraft with Discord, but when I use "JDABuilder" it keeps giving an error. Can someone help me? (I've already tested 6 versions of JDA)

[lost matrix]

Use the latest

[buoyant viper]

send the code ur using to create it? (and dont include the bots token in the paste)

[final star]

Wait a moment

are you saying that my message is too long ;-;

Could you send it to your private?

[lost matrix]

Do you get a compile time error or a runtime error?
Send the stack trace

[final star]

I can't send any files, but it's at runtime

[lost matrix]

But you can send text. Just send us the stack trace

[final star]

ok

[mystic tartan]

when I teleport a player who was falling, it makes the "player fell" noise, is there a way to stop the sound from playing?

[lost matrix]

Try setting his falling ticks to 0

You dont shade JDA into your plugin.
Do you use maven?

[mystic tartan]

that prevents the fall particles, but not the sound

[final star]

yes i use maven

[lost matrix]

Change his velocity to a zero vector before teleporting

[lost matrix]

Do you have a scope set on the jda dependency?

[final star]

no

[lost matrix]

Add the maven-shade plugin to your pom:

  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>

And make sure that dependencies which are present at runtime get the scope "provided", like this:

and it's still giving an error

[lost matrix]

1. Latest version is 4.3.0_339
2. Make sure that you have the maven shade plugin in your pom
3. Actually use maven and dont build artifacts because then you are ignoring maven completely and you could just throw your entire pom in the trash

[glossy venture]

You dont have JDA loaded at runtime

If ur using gradle use shadowJar to make a jar with dependencies

[lost matrix]

Its imported or else it wouldnt even compile

[glossy venture]

For some reason gradle doesnt have that option by default

Nvm

Maven

[lost matrix]

Yeah the problem is that the dependency is not shaded.

[glossy venture]

True sorry

U need to find a way to include it in rhe jar

So that it gets loaded by bukkit

[lost matrix]

Ive sent him a setup for the maven-shade-plugin
But i think he builds artifacts anyways so the pom gets ignored completely ^^

[glossy venture]

Bruh

@final star if ur building artifacts use the include dependencies in project and then add JDA jar file

But rhen using maven is conpletely pointless

[little trail]

how can i get the uh player from an AsyncPlayerChatEvent

CTRL F is your friend

[lost matrix]

A plugin that lets you define a multiplier for every type of damage. Name it DamageControl

[wary harness]

any one can suggest how could I get rid of decimals in double
I got option in config to disable decimals for my economy plugin
but qustion is there a way to remove all decimals which shows sometimes
of double without DecimalFormat
because I currently only found suggestions using DecimalFormat that will turn it to string and then I need to get it back to double and save it to data base

[lost matrix]

Just cast it to an int

[young knoll]

String.format can display it without decimals

Or you can just cast to int

[wary harness]

wont work because it goes over max int

[lost matrix]

*long

[young knoll]

Cast to long

[vast shale]

Can someone help me figure out why this isn't working?

public static Map<Integer, Integer> trackExp = new HashMap<>();
public static Map<UUID, Map<Integer, Integer>> bdExps = new HashMap<>();

public void addPlayerExp(UUID playerUUID, int track, int exp) {
    if (bdExps.containsKey(playerUUID)) {
        int totalExp = exp;
        totalExp += bdExps.get(playerUUID).get(track);
        bdExps.get(playerUUID).put(track, totalExp);
        }
    else {
        Map<Integer, Integer> tempTrackExp = new HashMap<>();
        trackExp.put(track, exp);
        bdExps.put(playerUUID, trackExp);
    }
}

public int getPlayerExp(UUID playerUUID, int track) {
    if (bdExps.containsKey(playerUUID))
        return bdExps.get(playerUUID).get(track);
    return 0;
}

Invoking "getPlayerExp" results in

Cannot invoke "java.lang.Integer.intValue()" because the return value of "java.util.Map.get(Object)" is null

[lost matrix]

If thats not enough then go for a BigInteger...
But max value of long is about 9.2 Quintillion which should be enough for most cases

[young knoll]

MapMaps

[lost matrix]

First:
If you see nested collections then its time to create some new classes.

[young knoll]

Or

Guava tables

[vast shale]

Is nesting hashmaps ineffiicient?

[lost matrix]

Eh. If its exactly one MapMap and you have exactly defined relations then sure... but as a general rule: Make new classes

[lost matrix]

Why would it be?

[vast shale]

Im assuming thats why you suggest making new classes

[jade perch]

Is an antipattern to make maps in maps in maps

[lost matrix]

New classes just improve the modularity, maintainability and expandability of your code

[jade perch]

And it looks log dog sheet to

[ivory sleet]

I’d say yes

[young knoll]

Yeah I recently used a table for cooldowns, works well

[vast shale]

Hmm okay. How would I convert my nested maps into a class to hold the values?

[lost matrix]

I think that was a statement, not a question XD

[jade perch]

It was statement

[lost matrix]

  private final Map<String, Map<Integer, Integer>> trackMap = new HashMap<>();

To:

  private final Map<String, TrackedMatch> trackedMatchMap = new HashMap<>();

  public class TrackedMatch {

    private final Map<Integer, Integer> tracks = new HashMap<>();

    public void addTrack(final int key, final int value) {
      this.tracks.put(key, value);
    }

    public void removeTrack(final int key) {
      this.tracks.remove(key);
    }

    // And so on

  }

And make sure you enforce strong encapsulation. Meaning that you never make your data structures public and you never write getters or setters for them.

[jade perch]

My favorite class is abstractmap.simpleimmutableentry when I'm super lazy

[vast shale]

Great, thank you, however, I'm still confused on how I'm supposed to get the value from a nested hashmap

[lost matrix]

Dont use nested maps

[vast shale]

But how can I save the values to a specific UUID now using your way?

[lost matrix]

Example for the class i wrote:

  private final Map<String, TrackedMatch> trackedMatchMap = new HashMap<>();

  public int getTrackedValue(String holder, int track) {
    TrackedMatch trackedMatch = trackedMatchMap.get(holder);
    if (trackedMatch == null) {
      return 0;
    }
    return trackedMatch.getTrackValue(track);
  }

[vast shale]

Ahh okay, thank you!

Hello ! i search for CraftFallingBlock the noClip in 1.17.1 😢

in 1.16.5 it's this : ((CraftFallingBlock) liftedBlock).getHandle().noClip = true;

and i search for the 1.17.1

[lost matrix]

If you dont use moj mappings then the NMS source code is obfuscated.
So its probably something like A or af

[young knoll]

Probably not mapped anymore

Also what the heck is no clip

[lost matrix]

Read here how to apply the mojang mappings and work with 1.17 nms:
https://www.spigotmc.org/threads/spigot-bungeecord-1-17-1-17-1.510208/

[young knoll]

Mappings are for dweebs

[unique eagle]

it is not A nor af 😢 when the falling block falls it becomes a block

[lost matrix]

Do you want the FallingBlock to just disappear or fall through the world?

[unique eagle]

disappear

[lost matrix]

Then you dont need any CraftBukkit or NMS. This can be done with the spigot API.

[unique eagle]

how ?

because in 1.16.5 i use craftfallingblock and noClip

[lost matrix]

  @EventHandler
  public void onBlockLand(final EntityChangeBlockEvent event) {
    final Entity entity = event.getEntity();
    if (entity instanceof FallingBlock fallingBlock && this.shouldBeIgnored(fallingBlock)) {
      event.setCancelled(true);
    }
  }

  private boolean shouldBeIgnored(final FallingBlock fallingBlock) {
    return true; // Make a check here so not all falling blocks get ignored
  }

[lost matrix]

This will lead to bugs and lag as the blocks just fall through the whole world

[unique eagle]

ho

[young knoll]

They probably get killed past y-64

I still wonder why a no clip option exists in the first place

thank you !

Im having issues with opening a custom inventory. I printed out the player's current open inventory and it appears to be changing, but no GUI appears..

[young knoll]

What are you opening

[carmine nacelle]

hey so I have a list of player UUIDs, im trying to create a list of players FROM those uuids,

return new ArrayList<>().addAll()

Trying to convert all UUIDs to players and add them to the new list in one line with lambda. any ideas..?

[lost matrix]

Sure there are several ways

one moment

[carmine nacelle]

dope

[lost matrix]

One example:

  public List<Player> toPlayerList(final Collection<UUID> uuidCollection) {
    return uuidCollection.stream().map(Bukkit::getPlayer).filter(Objects::nonNull).toList();
  }

[lost matrix]

Its basically the same as:

  public List<Player> toPlayerList(final Collection<UUID> uuidCollection) {
    final List<Player> playerList = new ArrayList<>();
    for (final UUID uid : uuidCollection) {
      final Player player = Bukkit.getPlayer(uid);
      if (player != null) {
        playerList.add(player);
      }
    }
    return playerList;
  }

[carmine nacelle]

alright sweet thx for that, im trying to do something like

    // Gets all currently playing players
    public List<Player> getInGamePlayers() {
        return new ArrayList<>().addAll(uuid -> inGamePlayerUUIDs.forEach(Bukkit.getPlayer(uuid));
    }

with the little lambda arrow bois, they look high tech

am I close..?

    // Gets all currently playing players
    public List<Player> getInGamePlayers() {
        return inGamePlayerUUIDs.stream().map(Bukkit::getPlayer).filter(Objects::nonNull).collect(Collectors.toList());
    }

this should do

[tame elbow]

if statements not working

[uneven dock]

Hey guys,

I'm not sure if this is even possible but I plan to develop it if it hasn't already been done but...

Is there a way to redirect players who join a Java server on Bedrock or Pocket Edition to another server that is bedrock/pocket? If so, is there a plugin out there that already does it or am I gonna have to make one?

nevermind I found one

[twilit wharf]

does anyone know how to create a lobby system like hypixel? I dont want to know all the code, just how to approach it?

[uneven dock]

Lobby system like Hypixel meaning what exactly?

[ivory sleet]

#help-server

[twilit wharf]

open a menu, select a block, and get moved to the server

[ivory sleet]

Or are you going to code it?

[twilit wharf]

I want to code it

[ivory sleet]

well first of all you want to establish some sort of message broker

[twilit wharf]

do I need bungeecord api for that?

[ivory sleet]

Which in this case redis or rabbitmq could be alternatives

[uneven dock]

I would just use a pre-built plugin like SSX personally

[ivory sleet]

^

It’s a lot of work to make a proper lobby system

[uneven dock]

You get all the customization you want in config

and no Java coding

[twilit wharf]

    }

[twilit wharf]

I dont think ssx has the lobby thing, this is for like 40 lobbies, each holding like 30 people, and it randomly puts you in one when you join.

and you can choose what lobby you want by opening the lobby selector

[uneven dock]

Oh in that case you would want to use a proxy that has a team balancer no?

If someone could help me out in #help-server I'd be very grateful

If someone wants to assist you they’ll surely look in the right channel (:

[quaint mantle]

I've never coded anything before but I'm trying to make custom ores in 1.17. I want to replace all deepslate ores with a new custom ore; this is because custom blocks aren't effective as ores in my opinion. I believe I'd be better off replacing deepslate ores with new blocks if possible.

1. I need to rename all deepslate ore blocks, as well retexture all deepslate ore blocks.

2. I need to make a custom ore item, which would then need to be replaced with what the normal deepslate ore block drops.

3. I then need to remove the ore blocks from being able to be smelted, or if they're smelted, make it smelt into the custom item.

Is this something that is possible to do? ^

[twilit wharf]

yes, as long as there is a resource pack the user downloads when they connect to the server

[quaint mantle]

Yes, of course. haha

Is this simple or should I pay someone to do this for me? I've never coded anything a day in my life but I'm up for the challenge if it's not advanced.

[twilit wharf]

um, I havent done anything with changing blocks that are generated, so I cant gauge the difficulty. someone else will have to do that

understanding stacktraces can really help you to reduce the amount of time to wait for other people to help you...

[twilit wharf]

yeah ik

[quaint mantle]

First: We see the PluginCommand

[twilit wharf]

yeah

[quaint mantle]

Which is about your command.

[twilit wharf]

yeah

obviously

I just cant find anything wrong there

😦

[quaint mantle]

Did it said Caused by in the stacktrace? Or that is all you got?

[twilit wharf]

thats all I got

[quaint mantle]

how many commands do u have

[paper viper]

you are doing something fucky then

show your code

[twilit wharf]

4

commands

[paper viper]

only show relavant code

[quaint mantle]

show wat code u think that cause the error

?pastes

?paste

[quaint mantle]

if u have too much

[twilit wharf]

https://paste.md-5.net/tajeqomane.java

[paper viper]

how do you register it

does your command class implement CommandExecutor

[twilit wharf]

yes

[paper viper]

How do you register it then

[twilit wharf]

getCommand("staff").setExecutor(new StaffCommand());

like my 3 other commands that work fine

[paper viper]

what is ItemManager

[twilit wharf]

this is what StaffCommand uses from it: ```java
public static ItemStack vanish;

public static ItemStack[] createStaffItems() {

    vanish = new ItemStack(Material.INK_SAC);
    ItemMeta vanishMeta = vanish.getItemMeta();
    vanishMeta.setDisplayName(ChatColor.GOLD + "Vanish");
    ArrayList<String> lore = new ArrayList<>();
    lore.add(ChatColor.GRAY + "Toggles your total vanish");
    vanishMeta.setLore(lore);
    vanish.setItemMeta(vanishMeta);

    ItemStack[] inv = new ItemStack[]{
            AdminPanelCommand.createItem(), vanish
    };
    System.out.println("Created Staff Items");
    return inv;
}

[paper viper]

Does the Created Staff Items print into console

when you execute the command

[rough salmon]

A

[twilit wharf]

nope

[paper viper]

This doesn't make sense

org.bukkit.command.CommandException: Cannot execute command 'staff' in plugin StaffPlugin vA.01 - plugin is disabled.

it says plugin is disabled

but your other 3 commands work?

[twilit wharf]

wait, now they dont

they were a minute ago

[paper viper]

... that is useful information

it means when you ran the command, it made an exception so bad it disabled the plugin or something

[twilit wharf]

wait

so

I didnt notice this the first time

but upon initialization of the plugin

it runs into a error

saying it is already initialized

[paper viper]

Lmao then thats why

You can't initialize multiple instances of your plugin

you can only keep one instance and pass it around

[twilit wharf]

yeah...

I know exactly where that is leading to

thanks

yep

thats what the issue was

[quasi patrol]

I'm trying to wait in a for loop, but it is waiting like the delay in the for loop and than it runs everything instead of waiting the time, do the thing, than waiting again and all that.

[young knoll]

Use a repeating task instead of a for loop

[quaint mantle]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[opaque panther]

guys if I have a lot of functions which needs to check for event handler, can I make multiple event handlers for same event. do multiple event listeners of same event execute at the same time or in the order they are registered?

[young knoll]

Order they are registered I imagine

Generally it’s better to have 1 handler that calls multiple other functions

[opaque panther]

ohh

i didnt think of that

thanks

[opaque panther]

hey whats the best way to change a small part of a gui menu. I want the item in the menu to change to a grass block when they click on it and change them to creative mode, and vice versa. Should I make a whole copy of that and display back? Or is some efficient way possible?

[young knoll]

Just change that slot?

[elfin talon]

Hey I have a 5 min countdown. How can I let the boss bar run down?

[young knoll]

Use a repeating task to update the boss bar every second or whatever

[opaque panther]

i have a gamemode change event . How do i check if a specific inventory is open for that player

[eternal night]

HumanEntity#getOpenInventory

[opaque panther]

what would it return if player hasnt any open inventory?

[eternal night]

Read the javadocs

[opaque panther]

ok i read it, should have read it before asking

im dumb

[quaint mantle]

hey how can i check if a block that is not normally powered by redstone, is powered by redstone

specifically, a transparent block

[wild reef]

you could check the blocks arround the one you want to check. If one of them is redstone or something which can power your block, the condition is true

I think you are also able to check if the blocks arround have isBlockPowered on true (just read about that rn)

[quaint mantle]

should i use the BlockRedstoneUpdateEvent then

its osmething like that i can check for the actual event

[wild reef]

yea that should work too

[quaint mantle]

cool deal

[opaque panther]

hey how do I store player details for a tpa command which can be accessed by another class without using static hashmap? I made it using that way but I saw people saying static members are bad

[ivory sleet]

Not inherently but yeah

It’s probably better to just pass an instance which encapsulates a map instead

[opaque panther]

ok thanks

[acoustic widget]

Hello , any tips for access to config file outside the main class ?

[quaint mantle]

learning java?
or just look at the guide above

?di

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[acoustic widget]

I'm learning, that why i'm asking so 🤓 , I'll take a look, thanks

[quaint mantle]

in your main, make a public static MainClassName INSTANCE;
and in onEnable, at top of all code type INSTANCE = this;
then in another class, use MainClassName.INSTANCE.getConfig().....
you can access any method in main class

[ivory sleet]

😩

[acoustic widget]

I read that is not a good way to use singleton patern, and dependency injection better right ??

[ivory sleet]

Most scenarios yes

[quaint mantle]

why it is not a good way

[ivory sleet]

Anyways you shouldn’t have to pass your plugin instance to any other class

If it isn’t something which for instance neeeds the scheduler or smtng

[ivory sleet]

Read the article above

Or wiki page

Dependency injection

[quaint mantle]

i always use constructor (di, but i like constructor word more)

[quaint mantle]

you mean making a getter for it ?

[acoustic widget]

@quaint mantle If I understand dependency injection inject just what you need in the method of your class.

[ivory sleet]

So you’ve never ever used a setter?

[ivory sleet]

No?

[quaint mantle]

so what are the examples in that article

[acoustic widget]

here https://www.spigotmc.org/wiki/using-dependency-injection/ at the bottom

[ivory sleet]

Idk that article isn’t entirely written by me and iirc it doesn’t go over the best practices

But generally

[quaint mantle]

makes this

and then this

[ivory sleet]

Using singletons will make your classes have to tightly rely on specific instances

It can get hard to unit test

And you will experience a loss of reusability in long terms

So static singletons actually complexifies your code architecture as opposed to just passing dependencies

[quaint mantle]

so will it do anything bad to optimization ??

[ivory sleet]

Performance is negligible

[summer scroll]

I need help with cancelling player to taking out their helmet, so I equip helmet using packets to player, and I want prevent player to taking out the helmet, how can I do that?

[ivory sleet]

In terms of runtime

Though I’d argue for that passing dependencies is more optimized for the developer themselves

[quaint mantle]

so what should i do now

make a private MyPlugin INSTANCE;

[ivory sleet]

Well

[quaint mantle]

and make a public getter for it ?

i dont get it

[ivory sleet]

I can write an example

[quaint mantle]

is this what you mean ?

doing something like this

private static MainClass instance;

@Override
public void onEnable() { instance=this; }

public static MainClass getInstance() { return instance; }

// In class "Hello"
private final MainClass main;
public Hello(MainClass main) { this.main=main; }

// On enable in main class
command.setExecutor(new Hello(this)); 

Or use record classes

public record Hello(MainClass main) {}

[sullen marlin]

uh

I don't think that's what records are for....

[quaint mantle]

💀

But idl records ya

[ivory sleet]

class JavaPluginImpl extends JavaPlugin {
  @Override public void onEnable() {
    PluginScheduler scheduler = new PluginScheduler(this);
    this.getServer().getPluginManager().registerEvents(new ConnectionListener(scheduler),this);
  }
}
class PluginScheduler {
  private final Plugin plugin;
 
  public PluginScheduler(Plugin plugin) {
    this.plugin = plugin;
  }

  public BukkitTask runTask(Consumer<BukkitRunnable> action) {
    new BukkitRunnable() {
      public void run() {
        this.action.accept(this);
       }
    }.runTask(this.plugin);
  }
}
class ConnectionListener implement Listener {
  private final PluginScheduler scheduler;
  public ConnectionListener(PluginScheduler scheduler) {
    this.scheduler = scheduler;
  }
  @EventHandler public void onLogin(AsyncPlayerPreLoginEvent event) {
    this.scheduler.runTask(task -> {
      //TODO
    });
  }
}```
Typed it on phone but yeah

[quaint mantle]

ah got it

thanks

[ivory sleet]

In this way you avoid passing your highest order component (class extending javaplugin) to one of the lowest ordered components in the system

[acoustic widget]

Assuming what we are talking about dependency injection, Am I fine for accessing config in a command ?

public final class TestMaven extends JavaPlugin {
    @Override
    public void onEnable() {
        getCommand("test").setExecutor(new Test(getConfig()));
    }
}

public class Test implements CommandExecutor {
    private final FileConfiguration config;

    public Test(FileConfiguration config) {
        this.config = config;
    }
}

[ivory sleet]

Yeah

That’d be fine

[acoustic widget]

Thank you guys for help

someone help me

[opaque panther]

https://paste.md-5.net/otadapimok.java

someone help me

my tpa command is not working when I removed the static from hashmap

I dont understand it

help someon pleaasa af ap

\

/

how do I paste it

[drowsy helm]

oops didnt see the pastbin

[opaque panther]

in that code when I used static before hashmap it worked

But when I removed, it didnt

why is that so

what I dont understand is

[drowsy helm]

are you creating a new instance of TPACommands for each player? I don't see a reason why it wouldn't work

[opaque panther]

wait ill send main

?paste

[undone axle]

https://paste.md-5.net/

[drowsy helm]

also instead of using names i woudl recommend using UUIDs

[opaque panther]

why?

https://paste.md-5.net/inineyowat.java

[drowsy helm]

well UUIDs are unique to each player

[opaque panther]

oh

but names are too?

[drowsy helm]

yeah they can be, but its just better practice. Not that it will happen but names cna overlap

[opaque panther]

ok

anyway can you check the main class

if there are not errors

[drowsy helm]

hmm your code looks perfectly fine to me

[opaque panther]

I dont get it why isnt it working

this is discouraging

[drowsy helm]

if its working static but not non static that implies that you are accessing different instances of it

[opaque panther]

https://www.youtube.com/watch?v=DaH3PFwKsoY&list=PLfu_Bpi_zcDNEKmR82hnbv9UxQ16nUBF7&index=17

in this video

he makes flying plugin

in 7:01

he makes non static arraylist to store players and it works

but why doesnt the map work when I do

[drowsy helm]

so static is the only thing youve changed right

no logic in code or anything?

[opaque panther]

nothing

[drowsy helm]

have you tried to debug the contents of the map?

[opaque panther]

let me check it

[drowsy helm]

itll help show which bit of the code is failing

[opaque panther]

ok ok

[random isle]

did someone know how i get a ItemStack from a id likr this 1:3 in the version 1.17.1

[drowsy helm]

as in a number id?

[random isle]

easyly i will get a itemstack from a number id. In the past it was Material.getMateriel(int) but doesnt works

[drowsy helm]

unless you make your own lib to map number ids to a material, no

all traces of number ids were removed a while ago

[vagrant stratus]

names are changeable

[random isle]

but why it was a realy god and easy system

[drowsy helm]

not really

you had to remember a bunch of arbitrary numbers

imagine if everyone on earth had a number instead of a name, its just harder lol

[random isle]

yeah ok but why not number and the new system

[drowsy helm]

minecraft stopped supporting numbers not spigot

[vagrant stratus]

number's completely useless with the new system lol

[drowsy helm]

if spigot were to continue supporting numbered ids, they would have to make their own id for new items

adding even more complication to the process

[random isle]

yeah but i like the numbers more then the new system

[vagrant stratus]

oh well 🤷‍♂️

your only option is re-create the old method

[drowsy helm]

so did I for a bit, then i realised how useless it was

far easier to reference an item as its name than a random number

after all, you can implement your own method for it, will just take a bit

[vagrant stratus]

^ Material.GOLD_ORE is much easier to remember than whatever its id is

[random isle]

yeah it will but i have a shild with a id and like to get the item. Not everyone who create a shild like to write the word the most writing the number id

[drowsy helm]

I think the fact that we don't need cheatsheets to remember material ids speaks volumes about it's effectiveness

[random isle]

so i will my own class for that

[drowsy helm]

yeah you're going to have to

then create ids for the new items aswell

and sub-ids

[random isle]

yay it "makes" me smile

[vagrant stratus]

and maybe even sub-sub-ids

[vagrant stratus]

as of 1.17 there are 1058 obtainable items in survival mode, so ya know, good luck

[random isle]

i know i will get a old list from the internet and will complete then

[vagrant stratus]

still, good luck 🤷‍♂️
You've got quite a few new items to map to ids.... that's not even including 1.18+

[fallow merlin]

How do I make terrain generation with noise more variant?

most of it is pretty flat

with small hills scattered about

[vagrant stratus]

I can't wait to see the mess that is Pierre's implementation of the old system 👀

[random isle]

yeah i too vut when it works i am happy

[drowsy helm]

just use an enum

[vagrant stratus]

1k+ items, a bunch of entities, among other things

all because they like dealing with IDs more than the current Material.RED_BED situation

best part is they'll have to update it every time an update comes out

[drowsy helm]

pog

[random isle]

no for first its still for the 1.17 XD

[vagrant stratus]

You've still got a bunch of new things to make IDs for

then once 1.18 hits, you've got even more ids to create

1.19? Probably more IDs

[random isle]

yeah its ok i am a developer with many freetimeXD

for all minecraft 1.17 item you will need 1200 double chests

[vagrant stratus]

and I don't know anyone else who'd be willing to learn all the IDs needed just to use your resource tbh

[random isle]

yeah but i doo it what ever you will talk to me XD

[drowsy helm]

wait so lemme get this right, you'd rather write 1k+ LOC instead of maybe 3 extra letters

[vagrant stratus]

yes

[random isle]

in the 1.17 its round about 64.800 Items it makes me smile XD

[vagrant stratus]

god help the performance

and i don't see why it would be that high honestly

[drowsy helm]

64k?

that doesn't sound right

[vagrant stratus]

^

[random isle]

all obtainable and non-obtainable

[vagrant stratus]

that's....still way off

[drowsy helm]

i mean you could always just write a tool that generates ids automatically but it wouldn't retain the legacy ids

[vagrant stratus]

some items you can't even get in any way, shape or form anymore lol

so not only are you going to be writing a bunch of IDs, you need to test them all as well to make sure they're all correct lol

Gonna pray for the resource performance too

https://tenor.com/view/nbc-superstore-praying-gif-9684878

[opal juniper]

its just gonna be one big hashmap lol

[random isle]

easyly i take the creative inventory and a few other items like commandblock XD

[vagrant stratus]

https://tenor.com/view/bih-okay-florida-2x-brooker2x-gif-13490950

[random isle]

you will see

[opaque panther]

hey all I posted a thread about that tpa comand class in spigot forum https://www.spigotmc.org/threads/my-tpa-command-doesnt-work-when-removing-static-keyword-from-hashmap.531561/

[vagrant stratus]

Not that easy lol, you'd still need to get all the old ids

and make a bunch of new ones that make sense

[random isle]

yeah but yet i beginn, when i write here anymore then i end this never

[vagrant stratus]

can't wait to see that mess though 👌

[drowsy helm]

have fun

[opal juniper]

there is no way to do that nicely imo

[drowsy helm]

enum with mat, id and sub id is best way i can think of

[opal juniper]

oh wait we are in help-dev??? i assumed this was general cause optic was here

[vagrant stratus]

https://tenor.com/view/dr-paul-bearer-ill-be-lurking-for-you-lurk-lurking-just-here-to-lurk-gif-12113551

[vagrant stratus]

Yea, but that performance hit though lol

[drowsy helm]

theres no other good way of doing it without a performance hit lol

immutable hashmap?

sql database???

[vagrant stratus]

....using the new material system

[drowsy helm]

i think thats out of the picture rn lmao

[opal juniper]

new???

thats not new

[vagrant stratus]

Our boy Pierre wants to work with the old ID system

so I'm considering the current one new lol

[fallow merlin]

Trying to create a hologram after a player types in some text in chat, but getting this error:

When hooking into `AsyncPlayerChatEvent` ... is there another approach I could take?

Why can't you make a hologram async?!

[opal juniper]

Bukkit.getScheduler#runTask

its an entity

you cant async entity add

[hushed garnet]

so fire off a scheduled task inside the async event?

[opal juniper]

[hushed garnet]

interesting, ok will go try this. Thanks @opal juniper

[drowsy helm]

yeah you need to run a synchronous event in the async

[hushed garnet]

thought I had tried that already... sure enough just worked!

[valid solstice]

Block block = e.getBlock();
        Material block_mat = block.getType();

switch(block_mat){
                    case DIAMOND_ORE:
                        player.sendMessage("DIAMOND!!!");
                        break;
                }
``` why is this not sending me the diamond message?

e is from a block break event

[tardy delta]

did you register the event?

[valid solstice]

yup

[tardy delta]

isnt it Material.DIAMOND_ORE?

[valid solstice]

it sends me a message when the event gets fired

[tardy delta]

u

[valid solstice]

i dont think you need to put "Material" if its in a switch case

atleast thats what i know...

[opal juniper]

You dont

Show more code

the entire event listener

[valid solstice]

alright 1 sec

[quaint mantle]

It appears that 2 seconds have passed…

[drowsy helm]

switch cases on enums don't require you to declare the enum class

[valid solstice]

@EventHandler
    public static void onBreak(BlockBreakEvent e){


        Block block = e.getBlock();
        Material block_mat = block.getType();

        Player player = e.getPlayer();

        player.sendMessage("runned");

        Random rand_int = new Random();

        if(Prosperity.getPlayersAffected().contains(player)) {
            player.sendMessage("its");
            if (true) { //true will be changed to rand_int
                switch(block_mat){
                    case DIAMOND_ORE:
                        player.sendMessage("DIAMOND!!!");
                        break;
                }
            }
        }
    }```

[drowsy helm]

its static

don't make it static

[valid solstice]

the method?

[drowsy helm]

yes

[valid solstice]

why is that? its getting runned even its static...

[quaint mantle]

But it makes no sense

[drowsy helm]

its static abuse

is "its" being printed?

[valid solstice]

true ill remove it

[valid solstice]

yup

[quaint mantle]

Oh “ran” btw

[eternal oxide]

Do unsafeEnchanments break villager trades?

[drowsy helm]

try and print out block_mat

see what it prints

[drowsy helm]

as in the output item having an unsafe enchant?

[eternal oxide]

having, yes

[quaint mantle]

Mostly not… I see in some servers use shopkeepers with an enchant 30 sword and it didn’t break

[drowsy helm]

I don't think it does

[tepid thicket]

Hi, which event is called, when a falling sand block collides with a torch, and dies?

[quaint mantle]

maybe nothing?

lemme check

[tepid thicket]

I would like to cancel the action and let the sand block sit on top instead.

[quaint mantle]

why dont u check it too?

[tepid thicket]

Which event to use?

[lost matrix]

Should be something like EntityDeathEvent as FallingBlock is an entity

[quaint mantle]

oh right

yeah that is right

[lost matrix]

You can only send unload packets and then chunk packets again

[tepid thicket]

The EntityDeathEvent doesn't seem to fire for a falling sand.

Any other ideas?

[lost matrix]

Some things i would test:
EntityCombustByBlockEvent
EntityDropItemEvent
EntityInteractEvent

[sullen marlin]

EntityChangeBlockEvent

Pretty sure its that with target block as air

If not then probably no event, open a feature request

[tepid thicket]

I read, that the EntityChangeBlockEvent would only fire, when the sand block is placed, but not when it dies by a torch.

But I can check it out of course.

[lost matrix]

I see. But the EntityDropItemEvent looks viable too as it actually drops itself.

[tepid thicket]

Though the EntityDropItemEvent doesn't provide a spawn cause, so it might be hard to track right?

[lost matrix]

But you would have the Entity that dropped it.

[tepid thicket]

Ohh right. I thought of the ItemSpawnEvent. Let me check whether yours fires for sand.

[karmic mural]

I was given some good help yesterday but I can't seem to implement it... I created a thread, (Generating items from config) could I request some assistance there, please?

[eternal oxide]

I looked, I don;t see what you are stuck on. You have been given pretty much all you need

[karmic mural]

Indeed... I am aware of that, I've just been trying to implement the code and it seems I am not capable of that... I've been spending some time watching some java tutorials and a lot of googling trying to implement it properly.

[tardy delta]

Yea i thought that too

[tepid thicket]

Okay, so indeed the EntityChangeBlockEvent fires for the first air block. Then you could scan down in a hacky way.

But the EntityDropItemEvent also fires and has the falling block as dropper/entity, which makes it the clear winner.

The other events don't fire and can be ignored for the most past.

Thank you guys. 🙂

[stone sinew]

Why are NBTTagCompound.entrySet() values LinkedTreeMaps instead of normal objects like String, List, Double etc...?
Especially since you can't set a linkedtreemap in the compound.

tags.entrySet().forEach(entry -> {
    String key = entry.getKey();
    Object value = entry.getValue();
    
    String found = "None";
    if(value instanceof String) {
        compound.setString(key, (String) value); 
        found = "String";}
    if(value instanceof int[]) {
        compound.setIntArray(key, (int[]) value); 
        found = "IntArray";}
    if(value instanceof Integer) {
        compound.setInt(key, (Integer) value); 
        found = "Integer";}
    /*7 other if statements for other instances*/
    
    ConsoleOutput.debug("Tag: "+key+" Value: "+value+" Value Class: "+value.getClass().getCanonicalName()+" Instance: "+found);

[karmic mural]

I was given some code to help me with creating items automatically from my config, but I am little bit confused for the final part, what do I put there?

public class CustomItems {

    private static final Map<String, ItemStack> namedItems = new HashMap<>();

    public static ItemStack getNamedItem(final String name) {
        return namedItems.get(name);
    }

    public static void loadFromConfig(final FileConfiguration configuration) {
        final ConfigurationSection itemSuperSection = configuration.getConfigurationSection("Path.To.Super.Section");
        for (final String key : itemSuperSection.getKeys(false)) {
            final ConfigurationSection itemSingleSection = itemSuperSection.getConfigurationSection(key);
            loadSingleItemFromSection(key, itemSingleSection);
        }
    }

    private static void loadSingleItemFromSection(final String key, final ConfigurationSection section) {
        // Load the ItemStack from a section and put it in the Map
    }

}```
Talking about the last bit "loadSingleItemFromSection", wording confuses me a bit

I understand the "pathtosupersection" being just the path to the part of my config I want to get stuff from, but that "load the ItemStack from a section and put it in the Map" has me confused

[eternal oxide]

section.getItemStack

[karmic mural]

Right, but for the path it requires there, do I just put the string-value of section or something static to point it to the part of the config I want it to take from?

[eternal oxide]

the section is already extracted from the path

[maiden mountain]

Is it possible to have custom GUI on the player screen with spigot? like Hypixel has

[karmic mural]

I am just as confused. Do I just namedItems.put(key, section)? If I am completely off the reservation here, could you point me to the correct resource to learn more about this?

[lyric oar]

Hello, i would like to edit the name of a player above the head. Is it possible to do that with spigot?

[eternal oxide]

you are getting items not adding them

[karmic mural]

section.getItemStack insists on having a String path

"Load the ItemStack from a section and put it in the Map" has me confused a bit then

[eternal oxide]

yes, you use teh name of the item

[maiden mountain]

How do you create 2D GUIs like this?

[karmic mural]

yeah I am very confused. I am trying to create items from a config so now I am thoroughly confused

[maiden mountain]

Is it possible with Spigot?

[eternal night]

that is a scoreboard

[karmic mural]

Yes, it's a scoreboard

[fallow merlin]

technically its possible in vanilla

but spigot makes it easier

imo

[maiden mountain]

aaah oke

so am i able to change the position aswell?

Like on top of the screen

[eternal night]

no

[maiden mountain]

So how would you create something like this?

[stone sinew]

BossBar

[maiden mountain]

Alright, thanks for the help

[karmic mural]

Man I must be thicc as bread... I want to generate items automatically from a config, what's the most efficient way to do that?

If there's some article I can read, video I can watch or whatever that'd be great

I've been trying to find resources myself, figuring out from code I already have etc etc but I just can't seem to crack it.

[acoustic widget]

I'm looking tutorial with onBowShoot event, but I can't find this event in the documentation. (he's teleporting where the arrow hit) Maybe it doesn't exist anymore and replaced by ProjectileHitEvent ? Or am I looking at the wrong place ?

[lavish hemlock]

Man I must be thicc as bread...
I have never heard this saying once in my entire life.

[karmic mural]

Yeah well there you have me. I've been stuck at this for days, even with someone having written code for me I just can't understand how to use it? Like am I just that thick?

[opal sluice]

Hello, does someone knows how to create a new MobEffect (NMS)

Would like to give invisibility to an EntityPlayer

[eternal night]

just get its bukkit entity

and use the spigot methods

EntityPlayer#getBukkitEntity()

[opal sluice]

I can't do that since it's not a logged player

it will try to send the packet to the player to add the potion effect

[eternal night]

but you have an instance

[opal sluice]

sure

[eternal night]

oh

technically that should still work

[opal sluice]

?paste

[undone axle]

https://paste.md-5.net/

[opal sluice]

https://paste.md-5.net/qafusubehu.bash

Saying that the connection is null

@SuppressWarnings("deprecation")
MobEffect invisibilityEffect = new MobEffect(MobEffectList.fromId(PotionEffectType.INVISIBILITY.getId()), Integer.MAX_VALUE, 2);
pc.sendPacket(new PacketPlayOutEntityEffect(ridable.getId(), invisibilityEffect));

Tried that but doesn't work 😢

[hasty prawn]

ProjectileLaunchEvent is when someone shoots a projectile, ProjectileHitEvent is when an arrow actually hits something

[acoustic widget]

Yes ok, but where I can find event like this one : onBowShoot

I tried to search on spigot doc but i don't know how to find it

[hasty prawn]

ProjectileLaunchEvent

That's fired when someone shoots a bow

You just need to make sure it's a bow @acoustic widget

[elfin talon]

How can I set the skulltype?

[hasty prawn]

What version

[elfin talon]

1.12.2

[hasty prawn]

Are you trying to get a Player head or what

[elfin talon]

yeah

[hasty prawn]

If Material.PLAYER_HEAD doesn't exist, make a skull item with a data byte of 3

[plain helm]

guys how can i force a player to walk somewhere?

[hasty prawn]

Set their velocity, there's not a way to do that gracefully I don't think

[acoustic widget]

Ok so you are agree with me onBowShoot doesnt exist anymore right ?

[hasty prawn]

I don't think that ever existed If it did it's really really old

[acoustic widget]

I was watching a video on 1.13 (2018)

[plain helm]

and then tp them, right?

[hasty prawn]

I think you're looking at the name of the method and not the actual event name @acoustic widget. If you go watch the video again I'm guessing they use ProjectileLaunchEvent

[acoustic widget]

hahaha

you are right...

Sorry, I'm learning java dev, my mistake

Thanks !

[hasty prawn]

Setting their velocity should slowly move them towards whatever location you want, shouldn't need to teleport

[plain helm]

ohh

that's what i'm doing wrong then lol

i've been using this method

 target.setVelocity(vel.normalize());
 target.teleport(loc);

[hasty prawn]

Yeah you should just set the velocity

[plain helm]

i'll try that ty

[elfin talon]

LOC.get(i).getBlock().setType(Material.SKULL);
            Skull skull = (Skull) LOC.get(i).getBlock().getState();```

But how can I set the skulltype to a playertype?

[hasty prawn]

Hmm, I'm not sure. This was all changed in 1.13 so I don't remember how it was done, you might just have to do some Googling.

[elfin talon]

okay ty

[quaint mantle]

Hey, I'm trying to get player inventory information like so, I know I can use item.getType() and item.getAmount() to get the type and amount, is there something to get the slot it was in in the inventory as a number?

ItemStack[] items = player.getInventory().getContents();
        ArrayList<String> itemList = new ArrayList<String>();
        for(ItemStack item : items) {
            if(item != null) {
                // item.getType(), item.getAmount(),
            }```

[tardy delta]

what

[quaint mantle]

sorry let me rephrase

[tardy delta]

you mean get the index of the itemstack when its in the arraylist?

[quaint mantle]

I'm trying to build a list of items in a players inventory, I know how to get the item type and amount, but I'd also like to get the position (slot i guess?) of it in the players inventory

[rough jay]

hi, what about built in bukkit ORM? Is it good?

[opal juniper]

can’t you do like Inventory#getSlot

[tardy delta]

i think he means to get the original slot index or something

dont

manager.setupCommands(this);
        manager.setupListeners(this);
        manager.setupBungeeCord(this);

try ```java
Manager manager = new Manager(this);

instead

you understand what i mean?

i did it like this but that looks the same

private boolean setupChat() {
        if (getServer().getPluginManager().getPlugin("Vault") == null) {
            return false;
        }
        RegisteredServiceProvider<Chat> chatProvider = getServer().getServicesManager().getRegistration(net.milkbowl.vault.chat.Chat.class);
        if (chatProvider != null) {
            chat = chatProvider.getProvider();
        }
        return chat != null;
    }

also i don't know if the extra space before Vault in your plugin.yml causes it

i think it does

probably the rsp is null in that way

[tame elbow]

quick question, how would I go about constantly making zombie piglins angry at everyone all the time? I found the PigZombieAngerEvent in docs but dont know how to use it.

[tardy delta]

Cant you make them angry when they Spawn?

[tame elbow]

oh yeah, could i use zombifiedpiglin.setAnger(1);

or this zombifiedpiglin.setAngry(true);

[tame elbow]

i think this could work. thank you!

[verbal nymph]

Hey friends, I wanna make days a little bit longer my SMP using a plugin. Can I just set DO_DAYLIGHT_CYCLE to false while the sun is up and then set it back to true a few thousand ticks later or is that gonna cause some problems I'm currently not thinking of?

[opal juniper]

should be fine

the best ways are the ones already in minecraft

don’t work harder than you have to

[verbal nymph]

Haha true, thank you! 🙂

[noble knot]

Hi. I'm pretty new to Java. How would I fix this error?

[quaint mantle]

You need to pass an instance of your Announcement class into JoinListener()

[noble knot]

And how would I do that?

[quaint mantle]

Show more code

[noble knot]

In what class?

[quaint mantle]

That one

[noble knot]

k

Here

[quaint mantle]

Okay so

Instead of doing new Announcement() inside of the setExecutor

Make a variable for it

Announcement announcement = new Announcement();

[noble knot]

ok

[quaint mantle]

Then you can put setExecutor(announcement); and also new JoinListener(announcement);

[noble knot]

It's giving me an error

[quaint mantle]

What is it

Oh yea I see the red line under setExecutor

[noble knot]

It's yellow

[quaint mantle]

Oh ok I’m blind

Oh

Swap the parameters I think

[noble knot]

What parameters?

[quaint mantle]

new JoinListener and “this”

[noble knot]

Nope

Still red

[quaint mantle]

Wait

Confused. What is your announcement class and JoinListener class

Also I’m pretty sure you have to use registerEvents instead of registerEvent

That’s prob why it’s not working

[noble knot]

Ok thanks

I'm dumb

[quaint mantle]

No error now?

[noble knot]

Wait it doesn't work

No errors in console

[quaint mantle]

What exactly about it doesn’t work

I'm trying to debug my plugin because it lags the server

How am I supposed to pinpoint the exact location in the code that causes it?

0.39% 666.33% 0.33 s 333.17 ms 0.0 0.0k Task: Database$$Lambda$4362/0x0000000801797878(Single) I got this from /timings pase

You could run a timings report

Oh

Okay are you calling to the database on the main thread?

Probably

Database calls need to be executed asynchronously

it looks like it but

I am wrapping the calls in an asyncv scheduler

Hmm

Show?

[tardy delta]

Bukkit.getscheduler.runasync()

[toxic mesa]

How would u guys go about solving this issue:

• kicked with message asynchronous getNearbyEntities
• getNearbyEntities is never called
  Something is messing up hard here

[quaint mantle]

this seems to happen here:

    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        Map.add(e.getPlayer(), System.currentTimeMillis());
        Database.getInfo(e.getPlayer().getUniqueId().toString(), (result) -> {
            Map2.add(e.getPlayer(), result);
        });
    }

Ok show your get info method

[proud shuttle]

I'm look for a plugin which I can make teleport command so like I can do /plots and it teleport me

[quaint mantle]

Also I hope you aren’t mutating the Map2 asynchronously or you’ll have problems

inside getInfo:

        Bukkit.getScheduler().runTaskAsynchronously(plugin, () -> {
            try {
                int result;
                PreparedStatement statement = connection.prepareStatement(Queries.get_info);
                statement.setString(1, uuid);
                ResultSet set = statement.executeQuery();
                if (set.next()) {
                    result = set.getInt("info");
                } else {
                    result = 0;
                }
                set.close();
                Bukkit.getScheduler().runTask(plugin, () -> callback.accept(result));
            } catch (SQLException e) {
                Logger.logError(e);
            }
        });

That looks fine, only thing I see is you not closing the connection

Are you using a connection pool?

no

I would suggest looking into doing that. HikariCP is a good one.
Also you never close the statement either. Closing the resultset doesn’t close the statement, however closing the statement should close the resultset

oh

so am I supposed to replace set.close with statement.close?

Yep

You could leave the set.close if you want, for clarity

And put the statement.close after it

Basically you want to close things in the reverse order that you made them

yeah
