both damageable and non damagable items will go through this code
so that wont work
it seems like just about any itemmeta is an instance of damageable

will that return even if an item is at full durability?

try checking damageable.hasDamage
still lets items without durability through

how do i add the dependency

how do i add the dependency
Just import the jar in your project
And them find the main class name
PluginManager#getPlugin("name") will return you a singleton instance of the main plugin class

Also you can import in maven as
<scope>system</scope>
<systemPath>path/to/file</systemPath>

That's deprecated

The solution to this issue is simple, either don't use CraftBee or make your own custom entity tile entity if you can even do that
echo basalt

what if
we make our fancy entitytype
because your example just uses the bee entity type

I rememver vivian having a problem where he wouldn't know if it was a minecraft bee or his custom bee

Stop drinking and coding

if i have a custom event that has methods to set value

Why do items given by spigot have 2 tags on them?

will the changed values run when i make a listener for the custom event

how would i go about spawning ambient particles such as void particles ? around a lobby or something
but only temporarily
slate mortar
but only temporarily
well, there's World#spawnParticle
sacred mountain
well yes i'm aware
im thinking about everywhere around the spawn and theres got to be a better way than spawning hundreds of particles
slate mortar
well i dont think so
i mean
there's the offset parameters - maybe theyre the "distance" in which the particles spread out?
idk i never used particles
echo basalt
uhh
you can spawn fog particles by making a bossbar
but you gotta have a bossbar you can't really hide
I mean you can try calling setVisible(false)
sacred mountain
you can spawn fog particles by making a bossbar
interesting
what about the void? thats pretty much endless particles
is there a way to spawn them above the void
echo basalt
that's rendered client-side
echo basalt
the boss bar fog should give a similar effect
echo basalt
yes
sacred mountain
oh righ
sacred mountain
when you say fog
what do you mean
because most people disable fog in their video settings
and that isnt even particles

Would it be possible to get all armor stands in a world even if there is no player loading it?

Whenever I try to create a world, it times out

not nearly enough for what i want

infinite loop

?

Im loading a world using this code:
public static World generateWorld() {
WorldCreator wc = new WorldCreator("map");
wc.environment(World.Environment.NORMAL);
wc.type(WorldType.NORMAL);
map = wc.createWorld();
return map;
}
im not sure about this stuff but should it be async
servers will time out after a while of non response, and that method will take a while to complete
and nothing else can happen whilst its running if im correct
but i would wait for someone with a better knowledge lol

somber hull
So I’m not currently at my pc, but I’m trying to think of how to fix a problem I have been having with a plug-in.
I have a list of spawners stored in a gui. In each spawner there is a PDC containing the type of spawner + the last time xp was generated. The xp bit has been working great, However I am trying to implement drops support so people can collect the spawner drops.
My idea for how to do this was to add another PDC for the last time items were generated, but that won’t work as I want them to be able to take just a few items at a time.
Essentially I need to figure out how hypixle skyblock minions work, as that’s the exact type of storage I am trying to achieve here.
I can’t figure out how to calculate the drops
Long story short
zenith saddle
can;t do worldgen async
you cant?
eternal oxide
no
eternal oxide
very
zenith saddle
why not?
sacred mountain
i need help with ambient particles
smoke_large seems to be the best bet, but they dissapear way too quickly
and spawning them constantly will decrease performance
is there a way to set their decay time
eternal oxide
You can test it if you want. Just throw yoru worldgen code in an runTaskAsync
or whatever its called
Particles have a fixed animation/life
sacred mountain
ah shet
eternal oxide
you can control their position and direction/randomness is all
sacred mountain
you can control their position and direction/randomness is all
hm ok well
how should i go about creating a cloud that will obscure most of what's behind it
does areaeffectcloud have that option
i was think an explosion but that only lasts for a fraction of a second and lags the client
eternal oxide
how should i go about creating a cloud that will obscure most of what's behind i...
think less of making a BIG wall to obscure, and move them much closer to teh player to obscure each players vision
You can spawn a lot less particles then and have them much denser
sacred mountain
so basically i have 8 'gauntlets' surrounding the player(s) and i want them all to become obscured temporarily whilst i do some particle show or sum
but i wnat the rest of the stuff to be visible
eternal oxide
I don;t believe there is any particle suitable to cover a large area
sacred mountain
like i want them to be able to see the obscured place clearly, i know it sounds a bit weird but yea
sacred mountain
I don;t believe there is any particle suitable to cover a large area
hm ok
i was also gonna ask, they added tinted glass.. does that have a density option? im just theorising i have no clue what it's properties are

Hi.
I've been trying to update my plugin to 1.19.1 but cannot figure out what's wrong..
I've ran BuildTools using "--remapped", added the dependency-related things to my pom.xml and still cannot get things to work. Some classes I am unable to import are: EntityPlayer and WorldServer.
Anyone that is able to help me with this?

You shoudl be importing ServerPlayer not EntityPlayer if you are using NMS
tardy delta
is it correct that you should run buildtools once to be able to use nms?
and then just using the spigot artifact
eternal oxide
no, you have to change your pom a little

You shoudl be importing ServerPlayer not EntityPlayer if you are using NMS

Should I send the packet after sending ClientboundPlayerInfoPacket?

yes

Doesn't seem to work... here's my code:
The goal is to create an NPC of the Player player
eternal oxide
you probably need to create a class which extends ServerPlayer
obsidian drift
Everything works well except for enabling the other skin layers
eternal oxide
in that, in its constructor you add this.getEntityData().set(Player.DATA_PLAYER_MODE_CUSTOMISATION, (byte) 0xFF);
obsidian drift
net.minecraft.world.entity.player.Player?
eternal oxide
yes
obsidian drift
DATA_PLAYER_MODE_CUSTOMISATION is protected

which is why yu create a class that extends SereverPlayer

not going to work
there's a vehicle move event
which would save the hassle of the has map
but you have to remove passengers to teleport the boat
supple elk
so that means the putting the player back on the boat every tick
which causes horrible visual bugs
I tried for over a day to get that to work
does changing the priority of the listener do anything?
I'd want it to be the last thing which fires before the boat actually moves
I don't understand why the velocity is kind of half of what it normally is tho
a period of 1 tick is the fastest right? That runs every tick...
oh wait
priority is on listeners
not runnables
it's definitely firing every tick...
so if the velocity is being set to 0 every tick how can it still move???

You can always try while loops. It will crash ur server tho

Store the SHA of teh password the player sends. You only store teh sha then check if your stored value matches each time.
no password to be stolen from your server/database

Issue is that it's not in JSON format, which is what ChatSerializer.a() expects
It's a text component

But again, you're really doing this the hard way
BaseComponent[] message = new ComponentBuilder("Ultra Jump : Progression Indisponible.").color(ChatColor.BLUE).create();
player.spigot().sendMessage(ChatMessageType.ACTION_BAR, message);```Or something similar to that. I'm writing based on memory
iirc you might be able to do just a new TextComponent() as well
TextComponent message = new TextComponent("Ultra Jump : Progression Indisponible.");
message.setColor(ChatColor.BLUE);

How do I cancel that
The method returns an int which represents the task id. You can cancel it using the BukkitScheduler.
But in most cases you want to use a BukkitRunnable that can cancel itself.
new BukkitRunnable() {
private int i = 0;
@Override
public void run() {
if(i++ < 10) {
Bukkit.broadcastMessage(String.valueOf(i));
} else {
this.cancel();
}
}
}.runTaskTimer(yourPlugin, 10, 10);
This runnable will broadcast 0 to 9 over the course of 110 ticks and then cancel itself.

Ok I've found a solution to the boat problem I've been having, almost
is there a packet which updates the location of an entity?
server thinks boat and player are in one place, player thinks they are in another
lost matrix
is there a packet which updates the location of an entity?
No. The clients just guess all the locations and hope they are right.
supple elk
they sync up eventually though?
every few seconds I'm warped back to the correct position
or if I leave the boat
lost matrix
Yes through packets. Movement is not fully server authoritative in minecraft.
cold tartan

supple elk

inland axle
No. The clients just guess all the locations and hope they are right.
they share the random seed and the client runs an identical algorithm so that they get the same values

then capture EntityDismountEvent and kill the invis entity, right?

if the entityMountEvent triggers on things like quitting the game
which ig it should
but still easier if I can go down the current route
cold tartan
yeah
eternal oxide
are you trying to lock these boats in place?
supple elk
The key was setting the position of NMS entity
meaning i don't have to dismount the player to warp the boat

Just create one runnable for all games and let it contain a List<Game>. Then your Game class has a tick method.
When the game finishes you simply remove it from the game runnable.
The game runnable always runs.
supple elk
do a new BukkitRunnable() maybe?
or use this syntax instead
runTaskTimer does the same thing as the method you called
zenith saddle
hmmm
supple elk
you can do this
the reason why you couldn't cancel is cause you created a new Runnable()
which does not have the cancel() function
lost matrix
I would do this
public class GameTask implements Runnable {
private final List<Game> gameList = new ArrayList<>();
public void addGame(Game game) {
this.gameList.add(game);
}
public void removeGame(Game game) {
this.gameList.remove(game);
}
@Override
public void run() {
gameList.forEach(Game::tick);
}
}
why, out of question?
is making a runnable for each game more expensive?
supple elk
you make a new Runnable
not a BukkitRunnable
BukkitRunnable extends Runnable
and has the cancel() function
lost matrix
is making a runnable for each game more expensive?
Not really. But it blurs the lines between the spigot api and your plugin.
supple elk

The server can not fully enforce the movement of vehicles for players
