You could use runTaskLater and loop through all online players to set that block to the new one and back with Player#sendBlockChange as gush said

I'd do a failsafe that you cache the tasks somewhere and manually call them if onDisable gets called

I would not change the blocks at all
I would just use Player#sendBlockChange
so even if the server crashes, the blocks are still intact

I have a question about jdbc database integration in a bungeecord server. I am recently using hikaricp for my connection pooling and read things about how too many connections greatly increase transaction queue times. Now i was thinking to make a sort of plugin that has postgresql jdbc and hikaricp. I would use this plugin as an api for other plugins to get connections from as i dont want too many plugins all making connection pools. I was wondering if i could make a bungeecord plugin that gives out connections to plugins inside a spigot server. Would this be possible?
Those spigot servers are connected to the bungeecord server ofc
wet breach
I have a question about jdbc database integration in a bungeecord server. I am r...
you do realize that Mysql can literally handle millions of connections
brave sparrow
Also no, bungeecord cannot give spigot plugins connections
wet breach
if you have long transaction queue times then you need to relook at your setup
brave sparrow
The spigot servers and the bungee servers are not the same
They can’t share resources
cerulean mirage
if you have long transaction queue times then you need to relook at your setup
I dont have that, i was just wondering if i could connect bungeecord plugins with spigot plugins
cerulean mirage
you do realize that Mysql can literally handle millions of connections
so i dont really need a connection pool?
brave sparrow
No
brave sparrow
so i dont really need a connection pool?
The connection pool isn’t for the database
Creating a connection on the minecraft server is slow
The connection pool creates a bunch of connection objects that wait for you to need them
cerulean mirage
yeah
brave sparrow
So you can establish a connection to the database much more rapidly
It has nothing to do with the actual database server
cerulean mirage
so 1 plugin api that has a connection pool per "sub" server on a main bungeecord server is fine?
brave sparrow
Yes
cerulean mirage
k thanks
quaint mantle
I never close a connection 🙃
wet breach
k thanks
keep in mind, that if you have issues such as connection limits being hit, you have to modify the db server config files. By default MySQL or MariahDB are conservative out of the box and most times this does alright.
brave sparrow
You should use a connection pool and close the connection to return it to the pool
tender shard
yeah default is 151 connections lol
that's like... 5 plugins using hikari
and you already hit the limit
wet breach
I never close a connection 🙃
this is impossible if you are using TCP, unix sockets are different so doesn't really matter except memory being exhausted possibly in this way. But TCP there is a max time frame a connection can be active.
cerulean mirage
hikari points out that having too many connections based on cpu core count is discouraged
this same for amount of connection pools?
wet breach
hikari points out that having too many connections based on cpu core count is di...
I think its referring to the amount of pools and not the connections themselves
tender shard
hikari uses a connection pool itself
cerulean mirage
wet breach
Yeah, you don't want a lot of pools, this is a waste. Pools are similar to Worker queues
too many of them and you just have a bunch of useless objects doing nothing and occupying resources
brave sparrow
The point of that is you want a pool that isn’t too large
So basically your threads can block more and CPU time isn’t being split across that many threads at once
A saturated pool will be faster than a larger pool that lets all your threads progress
cerulean mirage
would you need to split up connections per pool based on cpu core count
like lets say
you have 16 cores
thats 32 threads
but you need 3 pools
would you do 3 pools with 32 connections
or 3 pools with 10 connections
cuz they are still on the same cpu
brave sparrow
Why do you need 3 pools?
cerulean mirage
we have multiple spigot servers on the bungeecord
brave sparrow
Ah so it’s 1 pool
cerulean mirage
how
brave sparrow
Per program
brave sparrow
So 1 pool
cerulean mirage
which other plugins can request pools from
tender shard
would you do 3 pools with 32 connections
the pool should automatically scale. Like it should open new connections once 80% or 90% of the connections are in use or sth like that
cerulean mirage
So 1 pool
how would i have only 1 pool if i have 3 spigot servers that all need database?
brave sparrow
Because each spigot server is independent
brave sparrow
Each spigot server is running in its own JVM
Don’t think of them additively, there’s a lot more going on
It’s 1 pool on each server so optimize that 1 pool independently of other servers
cerulean mirage
k
So we have 24 threads. Best to do 3 pools with 8 connections or 3 pools with 24 connections?
We talking about the cpu now
each spigot jvm has a pool
3 spigots on a bungeecord
brave sparrow
Don’t think of them additively, there’s a lot more going on
.
cerulean mirage
k
brave sparrow
How many cores do you have
brave sparrow
connections = ((core_count * 2) + effective_spindle_count)
wet breach
We talking about the cpu now
cpu only matters in terms of objects, the connections themselves are not based on your cpu

Getters are one of the most common methods in Java :p
lunar flax
So I need to do java public static FileConfiguration config; in main and java config = getConfig(); in onEnable?
west oxide
i think even if he helps you now you'll still have to learn about getters
Here's an example of getter you can do (am also still new to this btw)
yeah but they asked for it lol
lavish hemlock
Lemme show you a better example
This is a common pattern in Java called a POJO/DTO (Plain Old Java Object/Data Transfer Object):
public class MyData {
private final String s;
public MyData(String s) {
this.s = s;
}
public String getValue() {
return s;
}
}
It does two things:
misty current
private int iteration;
@Override
public void execute(Player player, String[] args) {
iteration = 0;
int arg1 = Integer.parseInt(args[0]);
Location loc = player.getLocation().getBlock().getLocation();
Bukkit.broadcastMessage(String.valueOf(System.currentTimeMillis()));
for(iteration = 0; iteration < arg1; iteration++){
loc.getBlock().setType(Material.GOLD_BLOCK);
changeLocation(loc);
}
Bukkit.broadcastMessage(String.valueOf(System.currentTimeMillis()));
}
private void changeLocation(Location location){
switch (getDirection()) {
case 0 -> location.add(distance, 0, 0);
case 1 -> location.add(0, 0, distance);
case 2 -> location.add(-distance, 0, 0);
case 3 -> location.add(0, 0, -distance);
}
}
private int getDirection(){
int direction = 0;
int iteration = this.iteration;
for(int j = 1; true; j++) {
for(int k = 0; k < 2; k++) {
iteration -= j;
if (iteration < 0) return direction;
direction = (direction + 1) % 4;
}
}
}

You'll commonly see classes like this when you need to store multiple values in one.
Also, you can add a setter if s is not final (AKA if it's "mutable")
Because mutability is bad in Java :)
And people need to learn constructors anyway

I got my code to work yay, But is there a reason why my random system is sometimes returning the TNT, which is meant to be a false value?
int totalWeight = 0;
ItemStack item = new ItemStack(Material.TNT, 1);
Random rand = new Random();
String rewardData = "Crates.crateRewardData.";
FileConfiguration conf = EmeraldsPlugin.jp.getConfig();
for (int i = 0; i < conf.getInt("Crates."+crateType+".Amount"); i++) {
String s = conf.getString("Crates."+crateType+".Items."+i);
totalWeight += conf.getInt(rewardData+s+".Weight");
}
double r = rand.nextDouble() * totalWeight;
for (int i = 0; i < conf.getInt("Crates."+crateType+".Amount"); i++) {
String s = conf.getString("Crates."+crateType+".Items."+i);
System.out.println(r);
if (conf.getInt(rewardData+s+".Weight") >= r) {
item = new ItemStack(Material.getMaterial(conf.getString(rewardData+s+".Material")), conf.getInt(rewardData+s+".Amount"));
}

I'd also like to explain why getters/setters exist
In object-oriented programming (y'know, where classes come from, and what Java follows)
You have a core principle known as "encapsulation"
Sorry trying to find a chart rn
lavish hemlock
You have a core principle known as "encapsulation"
Here:
The word, “encapsulate,” means to enclose something. Just like a pill "encapsulates" or contains the medication inside of its coating, the principle of encapsulation works in a similar way in OOP: by forming a protective barrier around the information contained within a class from the rest of the code.
In OOP, we encapsulate by binding the data and functions which operate on that data into a single unit, the class. By doing so, we can hide private details of a class from the outside world and only expose functionality that is important for interfacing with it. When a class does not allow calling code access to its private data directly, we say that it is well encapsulated.
The idea to make only the important, necessary parts of data/behaviour accessible publicly.
eternal oxide
for loop
quaint mantle
So basically goal of this code is to make block under player glowstone and replace it with last block but problem is that nothing happens
@EventHandler
public void onMovement(PlayerMoveEvent e) {
Player player = e.getPlayer();
World world = player.getWorld();
Block block = player.getLocation().subtract(0, 1, 0).getBlock();
Material type = block.getType();
if(type != Material.GLOWSTONE && type != Material.AIR) {
block.setType(Material.GLOWSTONE);
player.sendMessage("asd");
try {
Thread.sleep(1000);
} catch (InterruptedException i) {
i.printStackTrace();
}
block.setType(type);
}
}
}```See, by directly exposing a field as public, it makes it harder to encapsulate.

lavish hemlock
See, by directly exposing a field as `public`, it makes it harder to encapsulate...
On top of that, if you need to later remove the field in an update, anything that still uses that field will completely break.
With a method, you can just deprecate it.

tardy delta
section.getKeys(false).forEach
silver shuttle
section.getKeys(false).forEach
thanks
hardy swan
I know about the method
I will try that. I just wanted to know if there is a provided api for fundamentally changing the type of projectile from the source, I guess not.
I will see how
ancient jackal
You could take a projectile event and then delete the projectile, replacing it with the one you want
hardy swan
I don't think any event is fired, no patches for PathfinderGoalCrossbowAttack

So you need to change your spigot libraries to the latest version
In your case 1.18
If you don't use NMS then you don't have to worry about anything
lean gull
anyone have a tutorial for making guis with an Inventory instance?
quiet ice
Ideally you'd use a dedicated library for that
wanton remnant
In your case 1.18
Yeah i know but when i do that, spigot methods aren't recognized
quiet ice
Are you using spigot or spigot-api?
wanton remnant
i take the spigot used for running server
quiet ice
And which methods exactly are not recognized
quiet ice

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.
Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163
wanton remnant
:o thx u so much
quiet ice
That is why you should read the release notes
And perhaps you should use maven or gradle
viral crag
gradle is easy enough and is much better to integrate both maven and gradle dependencies
quiet ice
Or just be me and use your own build tool

how would i write a piece of code thats constantly updating (like a bossbar with a timer that updates with every second)
quiet ice
It is quite annoying to use an in-house build tool at first but after a while you get used to it and will feel the power

so im makin a server with guns, and i want to have an easy method of creating the guns. all guns need to have some basic stuff like reload speed and abilities and whatnot. is there any way to make like an easy manager for this?

Okay so is the delay in taskdelay in ticks or ms?

Okay so is the delay in taskdelay in ticks or ms?
Everything is in ticks
lean gull
no i don't mean something that can make the guns, i mean a java thing for me to make that i can add default values and requirements for the guns
vocal cloud
You'd have to set up crafting yourself somehow
viral crag
yeah i saw you change it

how to use the sound here?
public void onPlayerChat(AsyncPlayerChatEvent e) {
String msg = e.getMessage();
List<String> words = getConfig().getStringList("bad-words");
for (int i = 0; i < words.size(); i++) {
if (msg.contains(words.get(i))) {
e.setCancelled(true);
e.getPlayer().sendMessage(sc("") + ChatColor.RED + "Swearing Is Not Allowed!")
e.Player.playSound(Player.getLocation(), Sound.ENTITY_WITHER_SPAWN, 1.0f, 1.0f);
;
}
}
}```A gun interface
But if everything is going to work the same, just extend a gun class
Or have defaults in the interface

wdym?

oh lol my mistake
ancient jackal
``` @EventHandler
public void onPlayerChat(AsyncPlayerChatEvent e) {

e.getPlayer() not e.Player

e.getPlayer() not e.Player
man did too much C#
ancient jackal

ancient jackal
``` @EventHandler
public void onPlayerChat(AsyncPlayerChatEvent e) {
...
Types aren’t variables, you should save the player to a variable ‘’Player player = e.getPlayer()’’
And then just use that everywhere you used type Player accidentally and everywhere you used e.getOlayer repeatedly

well doesn't the stacktrace always exactly explain what the problem is?
ancient plank
Idk
tender shard
but yeah 99% of just send their stacktraces here without reading them
ancient plank
I've never accidentally used bukkit API async
tender shard
me neither but I've seen a ton of stacktraces from other people doing it lol
it usually tells you exactly that you are accessing API async and you mustnt do that

does anyone know what the ender pearl cooldown thing is called? like the fillup thing and how it doesn't let you use it
ancient jackal
?sike
tardy delta
show code
tender shard
does anyone know what the ender pearl cooldown thing is called? like the fillup ...
Player#setCooldown(Material) I think
lean gull
does it only work for types of an item, or can i also do it with like items that have a certain nbt tag
tender shard
it works for Materials
tender shard
you can of course listen to stuff like PlayerChangeHeldItemEvent and simulate a per item cooldown
so if someone switches from your custom diamond_hoe to a normal one, you remove their cooldown
and apply it back when they switch back to your custom model data diamond hoe

you try to access array[n] although array.length is smaller than n+1
you try to send a letter to 123 Some Street although there are only 122 houses on Some Street
ancient jackal
i said show code
BigDecimal[] arr = new BigDecimal[0];
BigDecimal bd = arr[-1];
tardy delta
-1 indexer of an array doesnt make sense
there is no -1th element
it starts counting from 0
so arr[0] is the first one
ancient jackal
Ok so if I do
arr[-1] = …
Then it should work right
tender shard
no
tardy delta
NO
