it's inside the die method within a NMS entity class.
So that would be odd if the die method gets called infinite times
eternal oxide
It will only run once
crystal pike
It does not
Last 3 times I tried, I had to shut down the server and kill 4k+ entities.
eternal oxide
Argue all you like. That code will run ONCE> if you find it being executed more then it is being called more. a runTaskLater runs once
you are spawning a new entity as it dies?
crystal pike
Yes. after a 20 tick delay
eternal oxide
and you are trying to kill all entities?
crystal pike
Well I get that part.
But when I kill the first, it just keeps spawning.
Even though only one has been killed
eternal oxide
then your code is not doing what you expect it to.
Your logic is wrong
If teh code keeps running, its being called over and over
crystal pike
I see what you are trying, but I don't get it.
I simply extended EntityMonster

is there no System.currentTimeSeconds() ?
Nope. Millis for Unix time and nanos for the native cpu clock measurement.
Millis is more precise relative to the absolute time and nanos is very precise regarding delta values.

threads can do tasks at the same time

The spigot server has one main thread. There are a ton of extra threads like the ones spawned by the BukkitScheduler
but in most cases you will never use them as they are used for internal stuff (exception are the BukkitScheduler ones)
Ill do some chores and then ill write you an example for threading.

Ok number one:
Understanding how the minecraft main thread works.
Minecraft is like many other games tick based.
This means the main thread wants to schedule N ticks every second. For Minecraft
this number is 20, which will result in 50ms per tick that can be used to run code.
If the code takes longer then the TPS (ticks per second) effectively drops down.
Some of the tick time is used by NMS code some by Bukkit/Spigot and
some by plugins. If the server has nothing to do then it just waits some milliseconds
so the tick takes exactly 50ms.
grim ice
o
eager hinge
so i can just create some kind of entity packet and send the location each tick?
lost matrix
nvm same shit i guess
Not quite. One uses reflections while the latter calls nms methods.

onyx shale
so i can just create some kind of entity packet and send the location each tick?
well yes,but actually no

first you create a entity then you call the spawn packet with it
eager hinge
do i need to remove the packets afterwards?
onyx shale
packets are more fragile.. they get bonked fast

I didnt read the posts above but are both methods not working?
Elgarl suggested the isSimilar() method from ItemStack
and i that you should use the PDC of the ItemStack. There is even a guide for that.

for example teleporting away with a packet spawned entity will remove it
once you come back

I’m not strict about threads however they should be used to distribute peoples problems in the help channels, once they have no use then they should be archived. It makes it easier to navigate those threads that are still unresolved. We have a channel for general off topic, in fact verified also. We don’t need one more.

takes more storage but is safer

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.

Any courses that claim to teach you java not by doing or by no example are usually bullshit

alright, thank you everybody for the help

The problem is that I can't delete the main world
Ok then if I comment it out it also does not work
fading lake
that depends
if you make a new one straight after I think its fine in 1.13 up, but on 1.8+ it leads to crash, fire burning hell on earth dearh destruction
maiden briar
It is not working, here is my code:
mainWorld.setKeepSpawnInMemory(false);
//Bukkit.unloadWorld(mainWorld, true);
File worldFile = mainWorld.getWorldFolder();
getLogger().info("Detected world folder: " + worldFile);
removeDirectory(worldFile);
mainWorld = Bukkit.createWorld(new WorldCreator(worldName));
if(mainWorld == null)
throw new RuntimeException("Could not create a new world!");
getLogger().info("Successfully regenerated the world!");
No errors btw

why are you throwing a runtime exception lmfao

overworld

The overworld can never be unloaded

It doesn't even print the generating, only this:

[07:57:58 INFO]: [DogLeader] Successfully regenerated the world!
I can sysout that too
maiden briar
Ok, do you know how to regenerate the overworld to a completely new world?
eternal oxide
once the overworld is loaded it is blocked from being unloaded by Bukkit
maiden briar
Yes, and they said I can't remove it in onLoad (and that causes errors)

if you want a new Overworld, delete the files/folders in onLoad of your plugin

hi i wanted to ask why i can not add servers dynamically with the api to bungeecord
@Override
public void execute(CommandSender commandSender, String[] args) {
final String prefix = "§c/addserver <name>";
if(args.length != 1) {
commandSender.sendMessage(prefix);
return;
}
String name = args[0];
int port = ServerManager.getNextFreePort();
ServerInfo info = ProxyServer.getInstance().constructServerInfo(
name, InetSocketAddress.createUnresolved("localhost", port), "added by command", false);
ProxyServer.getInstance().getServers().put(name, info);
commandSender.sendMessage("added!");
}
The command works, but when i add a server, every other server is removed from the list. An example:
The upper /server command was before issuing /addserver x, after i entered the command, server x appeared, but "lobby" and "test" were gone
im using the latest bungeecord build, i also tried it with waterfal#448 (newest) and a travertine version

ivory sleet
Well if it’s client sided, then you probably can’t trigger the animation yourself. Unless you fake a bow shoot maybe.

wdym?

From what I understand it might be the case that the client is acting on its own when the bow shoot animation is happening
Which means you cannot control it with a packet
However you could fake a bow shot

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply.

You can listen for the PlayerDeathEvent and set keepInventory to true.
Also check if the player is sitting on a pig and then simply kill it.
Spawn a new Pig in the PlayerRespawnEvent.

You could just remove the carrot on a stick and the pig. Then on PlayerRespawnEvent -> give him a new carrot and spawn a new pig.
