How can i put my proxy on the same server as my lobby?
jaunty night
wdym same server?
frigid ember
you canot asbest
if you mean running bungeecord and a spigot server together, like on 1 shared host you probably cant
jaunty night
I mean if you have a VPS you can run it on the same host
or just a dedicated host, or self hosted for that matter
but if you're talking about traditional minecraft hosting like mcprohosting you can not you'll need to buy multiple servers

Hello !
This occured
com.mysql.jdbc.PacketTooBigException: Packet for query is too large (4739923 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.```
When I do
```Java
private void connect(){
try {
Class.forName("com.mysql.jdbc.Driver");
this.connection = DriverManager.getConnection(this.dbCredentials.toURI(),
this.dbCredentials.getUser(), this.dbCredentials.getPass());
Logger.getLogger("Minecraft").info("Succesfully connected to the DB.");
} catch (SQLException | ClassNotFoundException e) {
e.printStackTrace();
}
}```I tried to set this "max allowed packet"
But nothing changes
wraith thicket
@hollow thorn if you want something to happen later, use the scheduler. Otherwise you'll block the main thread and nothing will happen on the server while you wait.
wraith thicket
It doens't matter which class you use it in, it matters which thread you're in
The server runs on (mostly) one thread. So unless you explicitly scheduled an asynchronous task, you're likely on the main thread
hollow thorn
so as long as its not in the main
wraith thicket
The main thread - again, the class is not important
@pastel fox Check out this thread: https://www.spigotmc.org/threads/acf-beta-annotation-command-framework.234266/page-17#post-3771974
@hollow thorn I feel I need to reiterate this. Just because you're in a different class, does not mean you're on a different thread.
wraith thicket
No
That's what I'm saying
The server runs on (mostly) one thread. So unless you explicitly scheduled an asynchronous task, you're likely on the main thread
hollow thorn
public class StaffWeaponUse implements Listener {
public class StaffWeapon extends JavaPlugin {
wraith thicket
You're on the main thread.
hollow thorn
are those the same thread
wraith thicket
Yes
wraith thicket
Ask yourself "Did I explicitly call an async thread?" - if the answer is no, then you're on the main thread
hollow thorn

I mean you can use timestamps/scheduler @hollow thorn , depends on what you doing
hollow thorn
i was making a plugin

Youre just confusing people lol

that adds in ranged weapons
i was just wondering if i could use a similar thing
for cooldowns
brisk mango
this guy doesnt know nothing about threads lol, just point him in the right direction instead confusing him with threads @wraith thicket
brisk mango
I mean what exactly are you trying to accomplish, explaine me please @hollow thorn
no u were talking something about threads
hollow thorn
oh i wasnt trying to achieve anything
brisk mango
huh?
hollow thorn
but i was just trying to help with the cooldown thing
brisk mango
bruh you havent even provided any info of you current code and more in detail what are you trying to achieve so we cant help you atm
hollow thorn
oh no the code there was fine
i was just trying to help with
the cooldown
because when i use the gun
it doesnt stop everything elese from working
as far as i can tell
wraith thicket
Fire it towards the air and see what happens
They probably shot towards some mountain or something - iterating like 100 blocks and then stops because it hit a non-air block
wraith thicket
Or, actually, even the sky uses VOID_AIR I think
wraith thicket
Yep - that's why the while loop terminates (the VOID_AIR bit, that is)
wraith thicket
As for a cooldown, generally you want to do it per player. What you'll do is make a mapping from the player's UUIDs (not the player object nor their name) to the time at which their cooldown ends. And when a player tries to use/do whatever is on cooldown, you check if their UUID is in the map and if it is, check if the current timestampe (System#currentTimeMillis) is higher than what's in the map
I don't think the regular /enchant command does that, ray - but you can simple use one of the countless online /give command generators to give yourself a sword with sharpness 100
brisk mango
public final class Main extends JavaPlugin {
private final Map<UUID, Long> players = new HashMap<>();

if(event.getEntity() instanceof Arrow && event.getEntity().getShooter() instanceof Player) {
Player player = (Player) event.getEntity().getShooter();
if(isOnCooldown(player) {
player.sendMessage("Youre on cooldown");
return;
}
//Your gun here
}
}
}, this);
}
private boolean isOnCooldown(Player player) {
if (players.containsKey(player.getUniqueId())) {
if (players.get(player.getUniqueId()) > System.currentTimeMillis()) {
return true;
}
players.remove(player.getUniqueId());
}
return false;
}
private void addToCooldown(Player player) {
players.put(player.getUniqueId(), System.currentTimeMillis() + 1000L * secondsL;

Hi everyone i have a problem wiht an anticheat
upper hearth
I've been having major issues getting a built in resource from the JAR file once it's built.
All I'm trying to do is copy the embedded file to the plugin's directory, but no matter what I do, getResource() returns null at some point. Even getResourceAsStream() is returning null.
Even if I move the file and the class I'm using to the same package, they return null. Any ideas??
fading owl
Show some code
I know that getProtectedDomain() sometimes is useful
iirc
i think thats the method name
upper hearth
Tried that, didn't work either.
upper hearth
It's in the same location as the class I'm accessing it from. So even if I do getClass().getResource("test.txt") it doesn't do anything
fading owl
lol
yeah so resource files dont go in the same directory as java files
your project layout should be
src/main/java
src/main/resources
getResource will look for "test.txt" in
src/main/resources/test.txt
upper hearth
The layout should be like that even if I'm not using Maven/Gradle?
fading owl
yeah, it's conventional.
upper hearth
Why would IntelliJ not lay it out like that if that's the case
upper hearth
It does, but normal Java projects aren't laid out that way by default even though they should be? 🤔
fading owl
Well, maven set the standard and gradle followed up with it. Prior to that the convention, which is still used, is the model to use your website URI reversed.
I.e
com.google.myproject
upper hearth
Yeah that's what I've been using
fading owl
sec
gradle follows this too
for unit testing you do
src/test/java
src/test/resources
or microbenchmarking
using JMH
obtuse rose
if you created the project with Eclipse/IntelliJ, by default resource and source code folder were the same folder though?
fading owl
i have intellij ultimate, if i create a java project with maven or gradle as dependency management it will create src at top level, followed my main/test follwoed by java/resources respectfully.
obtuse rose
that's when you use maven/gradle
upper hearth
I'm not using those. IntelliJ Community does the same thing.
fading owl
yeah so a baseline java project sure, why give the additional boilerplate
better to do things conventionally
unless u want to work alone forever
obtuse rose
just use maven/gradle, problem solved 👍
upper hearth
Not a fan of them.
obtuse rose
and it's easier for other people to collab too
because compiling is just a command
instead of download tons of stuff and add to project manually
upper hearth
Gradle isn't too bad, IMO Maven is a complete disaster.
I generally do personal projects, so there's no reason for me to put them on Github, so those don't really have a point
wraith thicket
Maven has nothing to with github
upper hearth
Gradle to an extent, yes
fading owl
so u would rather use nothing for dependency management
then gradle or maven
or do u use an alternative
or do u stick .jar files in a folder called /lib/ and call it a day
upper hearth
^ pretty much yep
fading owl
yup
fading owl
maven is super easy
they provide a 5 minute (really 20) on maven essentials
then u can spend a few hours indepth on their larger tutorial
then ur smooth sailing
upper hearth
Idk why but my maven never worked. I obviously did something wrong and just couldn't be asked to figure it out
fading owl
then u get the benefits of aggregation and inheritence
hallow surge
i have entire book on maven
wraith thicket
Everything is easy nowadays. You just google it.
fading owl
if maven never worked for u
u aint working for maven
communication is a 2 way street my dude
upper hearth
If I'm going to use a dependency manager I would just use Gradle. Is there a reason to know both 🤔
fading owl
yes
how could you decide to use gradle if u dont know maven
grass could be greener on the other side
wraith thicket
I'd say using one is a bigger step than knowing both.
fading owl
(its not)
hallow surge
atleast use oone -_-
hallow surge
Lol i love this kid on spigot he got book banned from his own server and made a post on spigot asking about the bobbing xD thinking it was a glitch
I hate like everybody thinks they can just run a server even though they arent qualified
obtuse rose
@hallow surge tbh, isn't that like the majority of people on SpigotMC forum?
hallow surge
im not qualified thats why I dont try to run my own server xD
@obtuse rose it really gets on my nerves when they dont even know mc in general
not only do you not know how to program you dont know the game
obtuse rose
😆
hallow surge
like okay your new to program but atleast know the game
obtuse rose
you would still need a bit of basic networking/programming stuff to run a server though
but those people who just download everything, throw it in plugins folder and call it a day....
I totally agreed with you @hallow surge 😅

lol
surreal sedge
does Collection<? implements ConfigurationSerializable> implements ConfigurationSerializable ?
or how can I retrieve the value of a list in a yaml configuration file ?
surreal sedge
oh, yes, you're right
but to what should I downcast the item I'm referencing ? Map<String, Object> ?
I have the following yaml file
leaderboards:
- leaderboard:
name: "main"
objectives:
- objective:
name: "kills"
display-name": "Nombre de kills"
- objective:
name: "balance"
display-name: "Argent"
it's different because It doesn't represent a scoreboard that can be displayed by the side like the minecraft ones
naive goblet
whut
surreal sedge
I display it with holographics display
naive goblet
and?
surreal sedge
so I can't use the org.bukkit.scoreboard.Scoreboard Interface 🤔
naive goblet
No? But you can still use the built-in yaml system in the api?
surreal sedge
yes... I implemented ConfigurationSerializable, but now how can I deserialize them ?
naive goblet
Certainly that provides you the most essential features of conguring
doesn't a method exist for that?
wait send ur code?
sturdy oar
You deserialize them as everything else
surreal sedge
for (Object o : conf.getList("leaderboards")) {
Map<String, Object> map = (HashMap<String, Object>) o;
String name = (String) map.get("name");
}
but I don't know how to get the second list
subtle blade
get() and cast, or getSerializable() for a generic version
getList() should also be castable
surreal sedge
I'm new to spigot So i don't know very much about it
but how can I get the second list ?
naive goblet
you can't ?
- objective:
name: "kills"
display-name": "Nombre de kills"
- objective:
name: "balance"
display-name: "Argent"
I think the fact that it's a list to begin with is a design flaw
It should be a section
naive goblet
using a key twice will mess it up ?
surreal sedge
maybe, I can modify it
what is a section ?
naive goblet
a key holding a map
subtle blade
leaderboards:
nameOfLeaderboard:
objectives:
kills:
display: "Number of kills"
balance:
display: "Money"```^
subtle blade
That's how I'd do it
surreal sedge
ok
and how can I retrieve the name "kills" and kills.display, for example ?
keen goblet
Hello guys, i need help
how to make chunks that do not discharge with the passage of a player from one chunk to another
naive goblet
FileConfiguration
.getString("leaderboards.nameOfLeaderboards.objectives.kills.display")
Knovobo wym by discharge?
surreal sedge
the fact is, that y a can have an arbitrary number of objectives
so how can I iterate of them ?
getList returns a List<?>, and I don't know to which type I have to cast it
subtle blade
ConfigurationSection has a getKeys() method to get the set of keys
It's a set of strings all being the entries in that section
surreal sedge
ok, thanks

basically, I made a plug-in to modify the knockbacks on my server but each time a player knockbacks from one chunk to another, the chunk unloads and reloads and it becomes a chunk corrupted with restart :/

Was thinking to simply changing to local ints

no, when 2 players fight and they change chunks, I would need a code which allows that the chunk does not move
the problem happens when a lot of people fight in the same chunks
and after restart

hello
i came back wanting to know if anyone still knows how to cancel an incoming packet from a clientnwith metty
netty
or is the only solution letting it succeed and ignoring it
i want the client to know that the packet has been canceled with the channel.writeAndFlush(packet).isCancelled()
when they send it
or isSuccess() isk
idk
is this possible, i am using netty 4.1
subtle blade
What are you doing
frigid ember
attempting to cancel a packet with netty
frigid ember
in the channelRead(ChannelHandlerContext ctx, Object msg)
idk why many people like context about why i do stuff but fo example i dont want clients spamming me with packets
maybe have a limit per second and the rest cancel
subtle blade
You're going to compromise the experience of your users by doing that
frigid ember
or if data is not readable cancel or select what i want
in my client and server it is not bornal for the user to randomly spam packets
that was an example
a good example maybe with minecraft is cancelling a position update @subtle blade
the client must know so he can teleort back
paper compass
Is this a good way to keep chunks loaded that I really need loaded? [1.8.8]
@EventHandler
public void onUnload(ChunkUnloadEvent e) {
if(chunks.contains(e.getChunk())) {
e.setCancelled(true);
}
}```is there a way than doing extra work server side and sending a packet to the client saying “cancel” that packet for example
paper compass
Really?
tiny dagger
yup
paper compass
woah
frigid ember
can i get a response quickly man i really gtg
tiny dagger
i don't know how the unload works if it got cancelled
paper compass
Should I just loadChunk?
and setCancelled
just incase
@EventHandler
public void onUnload(ChunkUnloadEvent e) {
if(chunks.contains(e.getChunk())) {
e.getChunk().load();
e.setCancelled(true);
}
}```choco???
tiny dagger
if you have the chunk instance that means its loaded
pretty sure of it
unless is a leftover chunk instance ie after an unload
tiny dagger
no it's fine
paper compass
kk
tiny dagger
it will work
bronze marten
Mbe do a Set<> with a custom object which only has a x,z
paper compass
Max chunks per player might be like 2-4
frigid ember
ok
tiny dagger
set uses more ram and has better cpu while arraylist is the oposite
tiny dagger
i dunno it can always get improved so :p
bronze marten
Rly think you should do an custom object with x,z variables there, unnecessary to store the whole chunk in a Set
frigid ember
choco im actually pissed now u made me wait so long why respond and then for no reason leave
just pop off
subtle blade
a good example maybe with minecraft is cancelling a position update @subtle blade
[4:46 PM]
the client must know so he can teleort back
This is EXACTLY why we have events
frigid ember
now u respond
subtle blade
Also, I'm not entitled to support you. There are literally 6,300 members in this Discord
subtle blade
Because I had been available at the time and was not afterwards
frigid ember
as the others didnt really comment i assume they don’t know
events are called by packets
i guess
subtle blade
The reason I ask for context is because often time people overcomplicate things for seemingly no reason
Everything on the server is handled by the client sending it packets
subtle blade
Depends on the event
frigid ember
playermoveevent
subtle blade
It sends back a packet to the client telling it not to move
bronze marten
There is?
frigid ember
wont it kill the server
subtle blade
frigid ember
if the derver does extra worki telling the client to stop
frigid ember
200 players with timer
subtle blade
It's meant to handle and distribute packets
frigid ember
server will die
subtle blade
It won't
subtle blade
You're severely underestimating the amount of packets that get sent at any given point
One mere packet will not do a single thing
frigid ember
when i debug all minecrafts lackets why dont i see this
why dont i see the server sending a packet not to move
subtle blade
because it sends a teleportation packet
subtle blade
CANCEL THE FUCKING EVENT, RETROOPER
lmao jesus christ
you don't need to sniff for packets
It's unnecessary
subtle blade
Client sends packet to move, server doesn't respond. Client assumes it's right, server thinks its in another position, server kicks player
The server has to send a packet
That is how it is cancelled
frigid ember
i thkught there was an inbuild way to cancel and the server wont deal with the packet
subtle blade
You're not going to out-smart the server
The events exist for a reason
It's to make your life easier
frigid ember
idk what you mean out smart

new BukkitRunnable() {
@Override
public void run() {
CompletableFuture<String> future = generateTopTenMessage();
future.thenAccept(message -> cachedTop = message);

private CompletableFuture<String> generateTopTenMessage() {
CompletableFuture<String> future = new CompletableFuture<>();
database.executeQuery(data -> {

int place = 1;
while (data.next()) {
sb.append(messages.getLine("topten.place", Messages.getPlaceholders("%place%", "%name%", "%shards%", String.valueOf(place), data.getString("name"), String.valueOf(data.getInt("balance")))));
place++;
}
future.complete(sb.toString());
}, "select name, balance from shards order by balance desc limit 10;");
return future;
}
The more I look at this, the more I think it's blocking
is thenAccept blocking the main thread or am I good
bronze marten
No its your completablefuture
Do CompletableFuture.supplyAsync(() -> { return value; });
dusty topaz
the future is completed in an async callback
that's not my concern (at least, I don't think so)
frigid ember
What is the way to get if a player is standing on a honeyblock?

anyone tried using https://mariadb.com/kb/en/about-mariadb-connector-j/ or any other connector?
i keep getting exception java.lang.NoClassDefFoundError: org/mariadb/jdbc/MariaDbPoolDataSource, but i added the .jar to the classpath
and imported into class
is is because of the creating normal java threads(ban/blocade)?
bronze marten
No your db execution happens bf you return the completablefuture
Which is blocking
dusty topaz
the future returns outside of the callback
it shouldn't block, i don't think?
i think the .thenAccept is blocking, though I'm unsure
bronze marten
is the database.executeQuery() method async?
dusty topaz
yes
bronze marten
ah ok, then its fine
.thenAccept shouldnt block afaik, but you could try .whenComplete
dusty topaz
whats the difference?
abstract panther
it cant be sync cuz u dont know when you will get the db response
it can take seconds if you have a shit load of data

abstract panther
yeah i meant that. sry tired and shit eng
subtle blade
.remove((Integer) 0)
woeful mural
Ah, thanks
floral isle
@crimson cairn the anticheat notify the player when he dony do anithing
bronze marten
@dusty topaz idk the real difference, but it seems to me they make no diff other that whenComplete returns also a throwable if it fails, - I dont think thenAccept has a blocking functionality
what makes you sure it blocks? is it noticeable in timings?
crimson cairn
@floral isle that's still pretty vague. can you elaborate how/when this happens?
dusty topaz
was just thinking how will .thenAccept be called
abstract panther
anyone tried using https://mariadb.com/kb/en/about-mariadb-connector-j/ or any other connector?
i keep getting exception java.lang.NoClassDefFoundError: org/mariadb/jdbc/MariaDbPoolDataSource, but i added the .jar to the classpath
and imported into class
is is because of the creating normal java threads(ban/blocade)?
@abstract panther bump. help pls xD
i tried everything
bronze marten
@dusty topaz they will store the function, call it when its done lol
its a Consumer youre passing through
crimson cairn
@floral isle Oh well that explains it. The check is designed terribly. No offense to whoever wrote your anticheat.
bronze marten
they just store it, and do .accept(<return value>) when the competablefuture is done
crimson cairn
get someone else to write your anticheat lol
dusty topaz
yeah, but if the .thenAccept is called on the main thread it may be blocking
since it has to wait
floral isle
the anticheat sends the warnings of the fly to a player who makes a pillar or hops continuously
crimson cairn
yeah
the check is garbage juice
get someone else to write an anticheat for you lol
floral isle
Yeah this Is a snapshot
bronze marten
it doesnt have to wait lol, the only waiting that happens is the writing of the reference variable to the inner Consumer in completablefuture
subtle blade
Some in development longer than you've played Minecraft
floral isle
@crimson cairn have an idea ti fix it
floral isle
Ok but i dont know Better method for this
crimson cairn
i mean, whoever wrote this clearly has no idea how the client works
floral isle
There are example of Flight module?
crimson cairn
nocheatplus
if you wrote this, I highly suggest looking into MCP and reverse-engineer how motion works in the game
for starters, the basic function for determining the next delta Y is:
((last delta Y) - 0.08) * 0.98
floral isle
THX the anticheat have problem only with the Flight
crimson cairn
and then there are quirks in the game
if abs(delta Y) is less than 0.005, it is clamped to 0
floral isle
Ok i must go THX for the he help
crimson cairn
below minecraft 1.9 (i believe) the client holds back on motion updates until the client has moved at least 0.03 blocks or if 20 client ticks have passed
alright, you're welcome

@abstract panther @subtle blade did you ever try using a sql connector framework?
keen compass
you would need to shade that connector into your project
abstract panther
i did
keen compass
The other option is to use mysql's connector which is already shaded in
abstract panther
i am using it but the connection breaks if there are no calles made in the respone timeout perion and i can not reconnect via code
i solved it by making "blank" requests but that aint a sloution
i dont have that kind of dc's in c#
xd
keen compass
that is where connection pooling comes in
keen compass
Something like BoneCP or HikariCP solves that problem and keeps connections alive for you
or you can implement connection pooling yourself
abstract panther
thank you
keen compass
but according to that link you specified it appears that having both mysql connector and mariadb connector on the same classpath can cause issues
spigot automatically shades in mysql connector into the server jar
mysql connector does work for mariadb btw
abstract panther
yeah but it didnt keep the connection. Ill try multiple options cuz its ez to replace
and in examples they use the framework just to get the connection and the rest is java.sql
am i right?
keen compass
yes, however they do discuss the issue with mysql and mariadb drivers being present
and how to resolve it
as for your driver not being found, I am not sure if you are actually shading it in or not or what build system you are using or if you are specifying the correct driver name. I recommend using maven as it is more reliable when it comes to shading in dependencies but up to you.
abstract panther
i have been lazy to learn maven cuz adding jar is the same as adding .dll in c#
frome the answers i got from another forum i added in the java build path in the order and export tab in eclipse ide
frome the answers i got from another forum i added in the java build path in the order and export tab in eclipse ide
@abstract panther for shading
keen compass
probably should check that if it indeed placed that jar in your jar like you expected it to
abstract panther
will i can chech with jar size
keen compass
but just because it is in your jar, doesn't mean it was also added to the classpath either
keen compass
merely placing a jar inside another jar doesn't mean its on the classpath automatically
anyways, I don't mess with ant build system so I am not all that familiar in setting it up properly. I mostly use maven because it tends to be more reliable and easier to do these things.
abstract panther
if adding to classpath is the same as referencing with maven i did use that
i use several other plugins in my plugin
and it works fine
i know only ant build
from college days
keen compass
well all I can tell you is that for whatever reason it is not finding the driver. There is only few ways this happens, and that is either you have the incorrect driver name or the driver is not on the classpath.
cloud crater
Google is always a start

3 before me. Think, google it, then if you really cant solve it then ask specific developers.

3 before me. Think, google it, then if you really cant solve it then ask specific developers.
@cloud crater did all of that
keen compass
sometimes googling fails because of not using the proper keywords and coming here can sometimes give some insight into that 😛
cloud crater
Yep
abstract panther
yeah found out that also got better at java googling
some the same stuff dont have the same name in java and c#
keen compass
just tack java to end of the google search, most times that works in finding things related to java XD

i downloaded Itemshop but how do i use it with boss shop pro?
cloud crater
Asked the developer of it?
keen compass
you can generally see the developers names for resources
and generally clicking on their name takes you to their profile page
where you can send them a message
fickle surge
he does not have discord
keen compass
that is fine, private messaging on the forums exists
fickle surge
no one can help me fast right now?
abstract panther
@keen compass also shame we cant use normal threads in plugins
cloud crater
People using my plugins contact me using private message on spigotmc or I link my discord 9/10 on my resource page
keen compass
@abstract panther you can
not sure where you get the idea that you are not allowed to
keen compass
there is Async tasks too
but you also don't have to use the Scheduler either, you can implement threads yourself
abstract panther
but you also don't have to use the Scheduler either, you can implement threads yourself
@keen compass i tried like 3 different ways and they didnt work xD
keen compass
then you didn't do it properly. But threads are allowed
abstract panther
then you didn't do it properly. But threads are allowed
@keen compass i made a thread but thread.sleep didnt work
forgot to say xd
keen compass
depends on how you called it
and how you are referencing the thread you want to sleep as well
abstract panther
Thread.sleep(miliseconds)
cant remember the exact code
its been 2-3 weeks i thinks
think
in C# it references the thread the code is in
keen compass
Thread newThread = new Thread {
@Override
public void run(code goes here){}
}();
newThread.start();
newThread.sleep(time);
}
very basic way to run a new thread. You can even have a class that implements Thread and put your code in the run method there as well.
abstract panther
Thread newThread = new Thread {
@Override
public void run(
newThread.sleep(time);
){}
}();
newThread.start();
}
i needed this
keen compass
There is many ways to do it. And no singular way is the best way either as it is all dependent on your code
abstract panther
need to read more java docs so many things are diffrent
keen compass
but, spigot API also helps with this too. There is methods in the API to schedule async tasks and the server will take care of the thread stuff for you
keen compass
just like your sync repeating task you found in the api, there is an async repeating task
if that is what you want
abstract panther
i found that few weeks ago
keen compass
Well just informing you, threads are allowed and are actually encouraged to use if the code will benefit from it 😉
abstract panther
this sql problem is the first one in 2 months that i cant solve 😄
tnx
i am also using something like clean arhitecture so i can replace any part of the plugin very easy
keen compass
ah, modularizing it?

yes
keen compass
sounds like a good idea if its complex 😉

Hey y'all I need help, When I use luckperms then I start my server to generate the files it just don't work it didn't do anything my server is 1.8 I my other plugins are ViaVersion I tried to uninstall ViaVersion to see if it change anything it didn't LuckPerms don't create any folder can someone help me?
Edit : It do that with all plugins
keen compass
Are you using the correct versions for 1.8
also take note that 1.8 is severely outdated
and that support for it is going to be very limited as well
if you can't solve problems on your own for 1.8 might want to think about upgrading then
frigid ember
Yes but when I used the latest built via version said like no built for 1.15.2
something like that
I might use 1.12 then
is there a way I can like not use all my world

Well there is your problem
need to add a color to the firework

@deft pollen
use that website to help generate the appropriate commands
deft pollen
I know my dear, but right now i can't access the mc server with my main account because i get this error, and i need to solve that first.
keen compass
well, with the server off, go into the server.properties and disable command blocks
should allow you to get it up and running to go remove that command block that is causing the issue or disable it
deft pollen
I already turned it off, the error is being caused because the item is in my inventory i guess, i already tried to delete the .dat player data of my account but i'm getting the same error
keen compass
you sure you deleted the right one? they are named after your UUID
unless it was the only one
deleting the player data file should cause you to be reset as far as where you were at and items in your inventory unless you have something that is giving you the item upon joining the server like a kit or something
deft pollen
Yes, i checked my uuid in namemc, and deleted it;
Hello everybody, I'm getting this error when i try to join the server after trying to create a firework via command block, anyone knows how to solve it?

This is more mathematics help
how much is 1.5899E12
1.58 trillion?
if so i've done something very wrong
keen compass
E12 means there is 12 more digits
sly kayak
keen compass
CPU's will only go so far out in floating points
frigid ember
Im thinking of e+12 then, but still rounding it says its above 10ms..
keen compass
IE precision as it is called
you need to put a limit on how many digits your floating points contain
and then do your rounding
If you don't do that, your rounding can be off by a whole number as well
due to that sometimes a 1 will generally be at the end of a very long floating point lol
it could be all 0's but there will most times still be a 1
frigid ember
but that is the rounded number to 3 decimal places along with whatever value it actually is, is above 10 so ¯\_(ツ)_/¯

@proud lynx that's because the spigot is outdated, whenever a new spigot 1.15 is out, it'll be outdated unless you constantly are updating through build tools.

hallow surge
public String loadString(String config_value) {
getConfig().getStringList("HelpMessage");
return ChatColor.translateAlternateColorCodes('&', getConfig().getString(config_value));
}``` how could I get the return to check every line in the string list rather than just oneeither return the string list or just use string concatenation
public List<String> getList() {
return getConfig().getStringList("help_message");
}
return the string list then iterate over it to send the message @hallow surge
if its a message
hallow surge
its a message
temedy so something like this could workjava return getConfig().getStringList("HelpMessage")
fluid marlin
public List<String> getMessgaeList(String path){
return getConfig().getStringList(path);
}
List<String> message = getMessageList("path");
for (String line : message){
p.sendMessage(color(line))

^^ @hallow surge
brisk mango
public String getStrings() {
for(String string : getConfig().getStringList("help_message")) {

}
}
@hallow surge
hallow surge
§ works in configs correct
brisk mango
no
hallow surge
okay
fluid marlin
If anyone here is familiar with NMS NPCs please dm me 😃
brisk mango
that would return formatted message as in the string list
my method
list:
- message1
- message2
and the method should return
message1
message2
i mean it doesnt matter if u loop through all strings in the string list or get them in 1 string
hallow surge
what would i put in my other class something like
String hlpmsg = plugin.getStrings("help_message");
p.sendMessage(hlpmsg);
}```its returning a string list isnt it?
brisk mango
no
fluid marlin
if its returning a string list then it should be List<String> helpmsg = plugin.getStrings("help_message");
hallow surge
lol
fluid marlin
if its returning a string then you need to do it like temedy put and yeah that works
hallow surge
than why are you argueing with it xD
fluid marlin
not being ignorant, just didn't notice what you said while i was typing chill out lmfao
jeesus people have such low patience these days
