Also don't run your sql queries on the main thread. You're going to experience issues very soon if you haven't yet.
frigid ember
Is WorldServer the same as MinecraftServer?
nimble sage
Remember to always run your SQL queries in the Main Thread and definitely not Async!

WorldServer isn't a server
a more fitting name for it is ServerWorld, as it's a subclass of the World class in the MC code, specifically for server-related worlds
frigid ember
Anyone mind givin me a hand, I'm having an issue with GSON
https://hastebin.com/ohofeqayox.cs is the error log.
MinecraftServer server = ((CraftServer) Bukkit.getServer()).getServer();
Yeah I got it
kind berry
so know the give command /give <player name> <object> <number>, well I am trying to make the part were it searches for the players and uses them for the command does anyone know how I should do that?
upper hearth
args[0]
frigid ember
What do you mean? Like run the give command to give every single player something?
upper hearth
Or the Player object from the string?
frigid ember
Whats the difference between EnumProtocolDirection.CLIENTBOUND and EnumProtocolDirection.SERVERBOUND? I'm having trouble spawning an npc and I don't know which one to use
If you just want to give everyone something use @a instead of a player name lmao
upper hearth
Or make the command /giveall
kind berry
@frigid ember no I'm not giving I'm making a command that when I type in the arg it will set a variable to that arg that arg will get player names tho
frigid ember
PlayerList playerList = ((CraftServer) Bukkit.getServer()).getHandle();
GameProfile gameProfile = new GameProfile(UUID.randomUUID(), "jim");
WorldServer world = ((CraftWorld) p.getWorld()).getHandle();
MinecraftServer server = ((CraftServer) Bukkit.getServer()).getServer();
EntityPlayer pl = new EntityPlayer(server, world, gameProfile, new PlayerInteractManager(world));
DummyPlayerConnection con = new DummyPlayerConnection(server, new DummyNetworkManager(EnumProtocolDirection.CLIENTBOUND), pl);
pl.spawnIn(world);
pl.playerInteractManager.a((WorldServer) pl.world);
pl.playerInteractManager.b(world.getWorldData().getGameType());
pl.setPosition(p.getLocation().getX(), p.getLocation().getY(), p.getLocation().getZ());
world.addEntity(pl);
}
Hey guys, when I spawn in a player I have to rejoin to see it, how do I fix it so it spawns when I type the command instead?
upper hearth
Bukkit.getPlayer(args[0]) will get the Player Object and you can use that to give them the item @kind berry
frigid ember
If you just want it to get all player names just run through a for loop and stick them in an arraylist?
frigid ember
You should probably learn the basics first
fading owl
^
frigid ember
He just said hes new and is trying to learn, how do those comments help him at all?
fading owl
Telling someone to learn the basics is helpful.
frigid ember
This isn't a place for us to spoon feed the basics for people, if someone wants to do that then that's on them, but we're not teachers
fading owl
Gotta walk before you can run.
frigid ember
He's asking for help on the basics
There's hundreds of guides and free learning material out there
Yes there is, and he choose this place to come for help
You can sit here and explain it if you want
wooden harness
or just do a simple google search 😅
frigid ember
My advice is to go away and use the available meterial to learn the basics. A for loop is used in almost every language, and is pretty much day one
frigid ember
No, thats a while
kind berry
I have tried google and youtube searches none have showed what I need
crimson cairn
that is a while too
wooden harness
crimson cairn
although my reply was supposed to be right to the point
kind berry
@wooden harness sorry I mean not for the for loop
frigid ember
A for loop is meant to be used if you have a set amount of times you wish to run. A while should be used if you intend to loop for an unknown amount of times
crimson cairn
yes
upper hearth
I rarely use while loops tbh
upper hearth
while(user entered something dumb) {
askIdiotAgain();
}
While loops are also great for never ending loops lmao
upper hearth
I've never ONCE used do while
I could never even really understand why they're a thing
kind berry
ok thanks I get what a for loop is but idk how to do the thing @frigid ember sed to do with the arraylist
fading owl
I find the most common use for a while-loop is generally when using a Queue or some Iterator implementation.
crimson cairn
yea
upper hearth
Oh yeah Iterator.next()
kind berry
for (Player target : Bukkit.getOnlinePlayers()) {
if (args[0].equalsIgnoreCase(target.getDisplayName())) {
upper hearth
I forgot that existed
kind berry
would that work?
crimson cairn
thats an enhanced for loop
fading owl
labels have their usage
crimson cairn
yea
fading owl
nested for-loops
frigid ember
Java docs are your best friend
fading owl
are a batch though
frigid ember
Wait hold up, why are you using a for loop to check if an argument is a players name?
crimson cairn
oh thats display name
fading owl
okay whew
upper hearth
Just use Bukkit.getPlayer(args[0]) @kind berry, no reason to loop through the players
crimson cairn
eliminate the loop @kind berry
fading owl
Player target = Bukkit.getOnlinePlayers().stream().filter(o -> o.getDisplayName().equals(args[0])).findAny().orElseThrow(IllegalStateException::new);
Seems a bit complicated for what he's trying to do lmao
crimson cairn
dont think so
fading owl
so there u go
upper hearth
He shouldn't be using getDisplayName anyways, the argument is the player name
upper hearth
lmao
fading owl
XD
crimson cairn
i could never figure out how lambdas work
fading owl
what confuses u young one
fading owl
o is a reference to the object in the stream
crimson cairn
yea
fading owl
-> indicates the usage of a functional interface
upper hearth
It's kinda like for each I think
crimson cairn
yeah
upper hearth
I mainly use them because IntelliJ yells at me if I don't :(
fading owl
aint nobody got time for that
crimson cairn
intellij autocompletion is OP
upper hearth
Tis
Although if I try doing List<String> strings = new ArrayList<>(); without importing ArrayList it will autocomplete to ArrayListOutOfBoundsException... So I end up typing List<String> strings = new ArrayListOutOfBoundsException() all the time
frigid ember
Rip
fading owl
rip wut
frigid ember
Dess and his autocomplete
fading owl
poor lad
upper hearth
It's sad yes
fading owl
regardling lambdas though, they're pretty helpful day to day
especially since the collection api is so broadly used and inherity supports them
definitely worth learning

how to check if their last block was ice so that the anticheat knows that they are not speed hacking
chrome edge
@frigid ember For anti cheats I usually use PacketPlayInFlying packet for checking their movement. You may save their last location that is acceptable for return and if the anti cheat detect something teleport them to the location.
Minecraft getBlock method is broken
If you stay on edge of block it gives you air or other blocks instead of you staying on
You can check under block with basic math.
frigid ember
i have tried most of those things and for some reason just cant get it
chrome edge
for (double z = -0.3; z <= 0.3; z += 0.3) {
if (location.clone().add(x, -0.5001, z).getBlock().getType() != Material.AIR) {
return location.clone().add(x, -0.5001, z).getBlock();
}
}
}```try to use it and feedback to me
chrome edge
yeah you can change as player location
but it's just example of what I meant to say. After try it, make your own method based on this method.
frigid ember
where should i put this?
chrome edge
just make a method for getting block
like public static Block getUnderBlock(Location location)
frigid ember
hmm weird it wants me to change it to void even tho its returning a block
oh wait
i the big dumb
chrome edge
put return null end of the code
frigid ember
yea
chrome edge
-_-
frigid ember
lmfao
https://gyazo.com/06446565c598a19c3f6892858ed0ccdf returns the block under yes
chrome edge
Okay. Try to understand what you did then make your own method for getting block. You may also make another method based on it.
Good luck
frigid ember
i am still confused i get on the method works but i dont get what i do next to see if it is Ice, or Packed ice so i cant false flag
chrome edge
if (getUnderBlock(location)).getType() == Material.ICE)
Why don't you know that?....
frigid ember
cause i am new to checking blocks and stuff i did more of the designing wanted to get into making plugins and ik a bit of java but searching thru docs i cant find anything
gentle socket
I have two servers:
Main dedi server for spigot (1.1.1.1)
Vps for bungeecord (2.2.2.2)
I have got dns records:
A hub.example.net to 2.2.2.2
A pvp.example.net to 2.2.2.2
Bungeecord config:
1st listener:
host: hub.example.net:25565
forced_hosts:
unconfiguredhost: unconfiguredserver
force_default_server: true
2nd listener:
host: pvp.example.com:25565
forced_hosts:
pvp.example.net: pvp
force_default_server: false
Connecting to hub.example.net brings to hub and is all good. Connecting to pvp.example.net brings to the hub as well though? If I change 2nd listener port to 25566 and use pvp.example.net:25566 to connect then it brings to pvp. Is it not possible to make it with default port to bring it to pvp server?
chrome edge
If you make an iptunnel for connection both server machine, it probably bridge together.
frigid ember
So after having a method that is a boolean to check if the player is on ice with the other method i would do what now to save it then remove after sometime i did a Map and it just errored alot earlier
frigid ember
I dont really get it tho how do i remove after sometime because last thing i did was runLater and it would error for it trying to remove stuff when it wasnt in it
gentle socket
@chrome edge do i need to use srv record to get rid of port numbers for ppl? Or that wouldnt work?
chrome edge
Firstly if you connect both server with iptunnel you should use 0.0.0.0:port
but if you want to get rid of port you can do it with srv record as you said
I'm not experienced with that. That's all I know.
gentle socket
on vps bungeecord i have:
servers:
hub:
address: 1.1.1.1:3001
And on dedi server spigot i have:
server-port=3001
server-ip=
empty ^^
is this wrong way?
chrome edge
Have you try use 0.0.0.0 both dedicated?
like hub:0.0.0.0:3001
and change it server.properties also
@gentle socket if you're using OVH or hetzner it'll be problem for you. There's DDOS protection that blocks iptunnel. You have to know how to setup up this things.
gentle socket
yeah im pretty new to this. I use OVH for bungeecord vps and local server center for spigot dedi
so if bungeecord vps gets ddosed, its only gonna reach that vps
thats the idea
chrome edge
I knew that was the idea well I've little experience what you talking about xD
If you under the dos attack it'll break the bridge and your players will fall.
due to ovh protection.
gentle socket
If I understood correctly, the ip address that you put into bungeecord to connect spigot server together goes through proxy and nobody can see spigot server's ip
only the ip bungeecord runs on
ooh
hmm
guess ill need to wait for someone to ddos us to see if its setup correctly xD
chrome edge
yep good luck xD

Hello. I just wanna ask a question. So my other owner might have my plugins, if he leak it, I worried I would get ban on Spigot. If that happens, will I get unban? I am just worried.
chrome edge
You are the responsible one. You may be banned from spigot.
quaint folio
Yes but I had no choice. I got betrayed by a friend I known for a long time. He just stole all of the server money. So I am worried if he is thinking to get me ban on Spigot. Does Spigot strict about this? :l
chrome edge
As I know unfortunately it makes you ban. When you buy/download the plugin, you accept to TOS.
quaint folio
My day can't get anymore worse surely. Thank you for answering my question. I really hope I am not getting ban anytime soon. I am sure this situation had happened before, just I don't know what will happen.

frigid ember
how would i do that?
Also, you should create an inventory and check if the inventory is an instance of it, better than checking for the name
steep acorn
is that a solution for me or for rbuh? 😅
steep acorn
thx i'll try
frigid ember
anyone know how to check if the chunk is loaded tho?
check what hawk does
So @steep acorn you should do that, as it might conflict with other plugins (inventories with the same name).
You should post the stack trace, because “it crashes” is pretty generic
FatalPacket was that to me?
yes
Well where do they do that because i not searching 20 files to find one thing
Block.getWorld().isChunkLoaded(Block.getX() >> 4, Block.getZ() >> 4)
but I dont think its because of chunk loaded
thats what i think too
what is line 34 in block utils
if (getUnderBlock(location).getType() == Material.PACKED_ICE || getUnderBlock(location).getType() == Material.ICE) {
return true;
}
public static Block getUnderBlock(Location location) {

}
}
}
return null;
}```@frigid ember there is no stack trace, it just stops working until i die and respawn
frigid ember
What stops working? The server?
steep acorn
no, the plugin.
its like its not on the server anymore
there are other cmds that stop working
Player player = (Player) event.getWhoClicked();
if(invent == null) return;
if(event.getClickedInventory() instanceof invent) {```
like that?cause this isn't working
chrome edge
@frigid ember did you check if there're not an air block?
'cause if there's no blocks under the player it returns null
return true;
}```and don't use method more...
Just save as data start of the code.
Block underBlock = getUnderBlock(location);
As I know, PlayerMoveEvent is controlling chunk before the its call. If you're using packets, make sure chunks are loaded.
frigid ember
One last time, is player.isFlying() meant to be updated when they stop flying without double tapping space?
If I am sure yes
chrome edge
@frigid ember if you're flying, it returns true
double space active and deactive
or player.setFlying(true)
frigid ember
but if they collide with ground rather than toggling it, isFlying() isnt updated?
chrome edge
yes
frigid ember
but thats.. kinda cringe
frigid ember
isFlying() would suggest the player is flying
chrome edge
That's correct. So what's wrong?
flying method in spigot means that player flying using default minecraft features.
double space

Hi all, I'm making a Plugin where Players can interact with NPC Players (EntityPlayers).
They are made visible to the Player via sending them a Packet to spawn an EntityPlayer. This all works well, but I now wish for Players to be able to interact with these NPC's by clicking on them.
I've also managed to get this working, by using the tradional way of injecting/removing Players and making use of the ChannelDuplexHandler and ChannelPipeline classes from a mix of different tutorials online.
For this simple task, I have chosen to not use ProtocolLib as a learning experience.
Now whilst the following works, I understand that it may not be thread safe or efficient.
For simplicities sake I've reduced everything down to one class, to what would be in a basic tutorial.
Could someone please let me know why the following wouldn't be thread safe / is inefficient?
And by extension how could I do something complicated like Packet Listening on another thread to make this more efficient?
public class PacketCancel extends JavaPlugin implements Listener {
@Override
public void onEnable() {
Bukkit.getPluginManager().registerEvents(this, this);
}
@Override
public void onDisable() {
}
@EventHandler
public void onJoin(PlayerJoinEvent event) {
injectPlayer(event.getPlayer());
}
@EventHandler
public void onLeave(PlayerQuitEvent event) {
removePlayer(event.getPlayer());
}
private void removePlayer(Player player) {
Channel channel = ((CraftPlayer)player).getHandle().playerConnection.networkManager.channel;
channel.eventLoop().submit(()->{
channel.pipeline().remove(player.getName());
return null;
});
}
private void injectPlayer(Player player) {
ChannelDuplexHandler channelDuplexHandler = new ChannelDuplexHandler() {
@Override
public void channelRead(ChannelHandlerContext channelHandlerContext, Object packet) throws Exception {
if (packet instanceof PacketPlayInUseEntity) {
// do stuff
}
super.channelRead(channelHandlerContext, packet);
}
@Override
public void write(ChannelHandlerContext channelHandlerContext, Object packet, ChannelPromise channelPromise) throws Exception {
super.write(channelHandlerContext, packet, channelPromise);
}
};
ChannelPipeline pipeline = ((CraftPlayer)player).getHandle().playerConnection.networkManager.channel.pipeline();
pipeline.addBefore("packet_handler", player.getName(), channelDuplexHandler);
}
whats the method to check if someone is jumping?
lament wolf
Can someone tell me what this part is for?
frigid ember
Ok so, i need to fix the problem with someone getting hit and them jumping making them go further then normal speed my AC Flags so anyway to fix this?
i have it stopping when taking Velocity but it just doesnt work after them getting hit and jumping
rocky canopy
hey guys, not sure if this is the best place to ask, I'm looking for a good grappling hook plugin and a weapons plugin that lets you use crossbows as block-destroying weapons
green hornet
how can i remove an entity safely without it crashing the server - ie http://paste.debian.net/1144497/
rocky canopy
the search bar has worked only so-so for me so far, wondering if anyone has some recommendations
(open source would be great!)
fleet crane
Entity.remove() lol
sharp dew
@lament wolf There is an action value and it can range from 0-4 and it does differnte things
fleet crane
Make sure you dont call it async
green hornet
i removed all entity.remove() and moved them to a single place where i wrap it in a scheduleSyncDelayedTask
that should have been fine right?
frigid ember
Would i just check if someone is Taking Velocity and there Y is changing should i then dont flag?
sharp dew
@lament wolf and for each action value you need to send different data, that is specified at the right of the action column
rocky canopy
also, how much performance do you loose by running a server inside a docker container?
i've heard networking can take a hit
lament wolf
@sharp dew So where I should insert these value ?
sharp dew
you should use a dataWatcher
agile flare
?
sharp dew
or you should use reflection to access the private fields of the packet
can i ask you what you need to do
@lament wolf you can also construct the packet by writing
new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.(ACTION), playerAffected)
lament wolf
new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.(3), playerAffected) should work ? @sharp dew
sharp dew
@lament wolf for the action you can chose between ADD_PLAYER, UPDATE_GAME_MODE, UPDATE_LATENCY, UPDATE_DISPLAY_NAME, REMOVE_PLAYER;
but yes it should work
sharp dew
you should change the gamemode of the EntityPlayer and set the action to update gamemode
lament wolf
Something like that:
bronze marten
EntityPlayer entity;
...
entity.setGamemode(2);
packet = new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.UPDATE_GAME_MODE, entity);
aPlayerConnection.sendPacket(packet);```?
sharp dew
yes
but
to set the gamemode you have to use player.playerInteractManager.setGameMode();
lament wolf
Yeah okay :relieved:
Ty
Another question:
If I want to move an entity, should I use Entity Position and Rotation or Entity Velocity ? I saw Entity Move but it doesn't do much good from what I understand
sharp dew
i know the the varius different packet are used to reduce data consumption and so if you don't move but only rotate you don't send the position data
but i think you should send Entity Position and Rotation
because normaly the client sends those packets
sharp dew
yes
lament wolf
Look at the parenthesis
sharp dew
Hi
lament wolf
What does that mean ? If I want to take 3 steps forward the X of the entity, I should do
frigid ember
hoo wana play minecraft
lament wolf
Such as (10* 32 - 7* 32) * 128
frigid ember
wat are you taking about
lament wolf
packet Entity Position and Rotation
sharp dew
i think the coordinates should be modulo 8 becuse that is the maximum ammount of blocks you can move with this packet. but i'm not really sure how to use it
maybe it's easier with the Entity Teleport packet
lament wolf
rather between 8 and -8 than module 8, no?
sharp dew
yes my bad
vale slate
try to look into other mobs like zombies, there should be the correct implementation somewhere
sharp dew
now i get it if you do (curr * 32 - prev * 32) * 128 it should work with any coordinates
lament wolf
let us assume that my entity is located at (30, 40, 30), I want to move it up three
sharp dew
because the formula calculates the delta of the coordinates
you should do (43 * 32 - 40 * 32) * 128
sharp dew
@lament wolf be sure to use int for doing the calulation and the cast it back to short
cuz it might overflow
lament wolf

cuz this is the constructor of the packet public PacketPlayOutPosition(double d0, double d1, double d2, float f, float f1, Set<PacketPlayOutPosition.EnumPlayerTeleportFlags> set, int i) { this.a = d0; this.b = d1; this.c = d2; this.d = f; this.e = f1; this.f = set; this.g = i; }
too many fields

Is using ProtocolLib thread safe?
eg. Just getting the ProtocolManager and adding a packet listener?
(Such as the tutorial on the bukkit page? https://dev.bukkit.org/projects/protocollib/pages/tutorial)
By thread safe I mean should I be putting this on a different thread because it's sending / receiving packets? Or does ProtocolLib do that for you?
hoary parcel
Why would you register a packet listener async, lol
sharp dew
i'm tring to implement a TabCompleter class but i don't if and where i should register it like with an eventListener

Guys can sb help me with my SKYBLOCK, i want some for free, bcs i have 1.13 server, and i download skyblock, and its not working
manic raptor
@hoary parcel I'm new to this, could you explain why you wouldn't? 🙂 I assumed that (most)code that is sending / receiving packets should be async.

Your listeners will be executed on netty threads
No need to run the register code async

What is the best method to get which player killed an entity?

Did you check if the player name is correct?
And you probably should use the player's UUID instead

How can it be replaced with null check. Surely an arrow also counts as an entity etc
red linden
because I check for the argument
@cold wharf Use an UUID fetcher

How to do that? Sorry I am new

It only return a player if there is one

Does anyone have suggestions for a good VPS provider? I am looking to spend around $60-100. I am currently hosting on my own PC. We average around 15 players and we have a ton of plugins. I have never seen it use the max 16gb of ram, but I have seen it at 14, so ram is important. More important is CPU, which usually runs at around 30% utilization (i5-6600k @ 4.4Ghz) but it spikes sometimes to max which causes a good amount of server lag
red linden
@storm vessel Location?
storm vessel
I am worried that most VPS's, which use server chips, won't have the clockspeeds necessary for a game server
Currently near Pittsburgh, though anywhere in the US will do
Preferably Eastern US
dusky herald
Then dont use a VPS
get a Dedicated Server if you're looking to spend around $60-100
storm vessel
I can find any for that price that aren't shitty
dusky herald
I'm using reliablesite.net rn
storm vessel
I could buy/build my own, but I want the benefits that come from having my server in a datacenter
Thank you
dusky herald
OVH is good as well, I personally don't use them because I've had transaction issues with the,.
but if you're going to spend the money, there's no reason to be on a shared VPS host.
storm vessel
I wish I could find a good hosting company that has servers with desktop chips
The 3950x would be perfect for MC
red linden
I heard good things of reliablesite aswell. I personally cant use them because I'm from EUW
storm vessel
@dusky herald My issue is that if I were to spend $100 I would be getting the cheapest dedicated server available which is usually worse than a good VPS as far as specs are concerned
dusky herald
¯_(ツ)_/¯
You said you have 15 players, I dont see an issue with using a dedicated server.
storm vessel
The server only started 25 days ago, so I am counting on expansion
dusky herald
Then wouldn't a dedicated server be your best option then? That why you're not using a shared VPS host?
storm vessel
Now that we are getting votes we get 10 new players per day. 2-3 actually play for more than a few days
boreal tiger
with 100$ you can get a good dedicated lmao
storm vessel
Yes, but for what I can afford, I can't find a dedicated server with good enough specs
boreal tiger
you said 60-100$
dusky herald
Maybe you're looking at specs way more than what you need right now; lol.
red linden
Soyoustart might also be a good start.
https://www.soyoustart.com/us/game-servers/
dusky herald
You could just get a dedicated server for now
and upgrade later
to fit the needs for your server
It's not really a crazy concept for a server to upgrade multiple times early in it's life.
storm vessel
I'm currently running it on my PC which has 32gb of ram, NVMe storage and a a mid level CPU that OC'ed the shit out of and I'm still having occasional lag. Before I installed plugins to optimize villagers and entitytracking I was at 100% utilization for 15% of the uptime
Ok, I'll do some research into that
dusky herald
I mean, the only thing that's really going to bottleneck you would be your CPU
NVMe storage helps, but not a great difference
and also seems like you could be experiencing more lag because your server isnt dedicated to your "server" yet
storm vessel
This is off topic, but I wander if optane is fast enough to store loaded in chucks instead of memory
storm vessel
That is true. It is also doing regular Windows desktop things aswell (I run my server in an Ubuntu Server VM)
dusky herald
I think a dedicated could work fine for your needs, and if not you can always optimize performance and upgrade later.
storm vessel
I could be underestimating the performance toll that is taken by running it on the same PC that I use for other things
dusky herald
The crazy, high performance dedicated servers are meant to hold a crap ton of players; but I dont see why you wouldnt be able to hit 75+
storm vessel
Yeah you're right. I do have room to optimize as entities spawns are barely nerfed and view distance is at 8
dusky herald
I cant even give a good estimate nowadays anyways, back when I actually ran my own servers a dedicated server was more than adequate enough to hold over 700 people
storm vessel
My thing is that I have so many plugins
dusky herald
but, I hear 1.15 has some performance issues, so
storm vessel
We are now up to 60, and I go through them periodically and delete any that we don't need
dusky herald
I would cut down on plugins, mainly the ones you DONT need.
storm vessel
I have done that a whole bunch already. Getting rid of dynmap helped a ton
dusky herald
But, it still won't help optimization too much, not unless you get rid of plugins that aren't necessary, and if they are actually active during a lot of the server run time.
yeah Dynmap is bad for that.
storm vessel
Could you take a look and see if there are any that could be causing excessive lag as far as you know?
I would greatly appreciate it
dusky herald
I'm sure plugins like SkQuery/Skript dont help a lot; but I don't know.
I imagine you're using them so you can customize the server a little bit
storm vessel
They are dependencies for other plugins
wanton delta
say I have abstract class A that has sub classes B and C. I want to add a method to class A that returns itself again. However, I want B and C to have this same method but return themselves respectfully. How would I go about doing this?
storm vessel
And yes. Like "enhanced vanilla"
wanton delta
public <T extends A> T setTrue() {
setBoolean(true)
return this;
}``` is basically kinda what i want to accomplishbut i cant return this
storm vessel
Respectfully?
dusky herald
@wanton delta I don't know, cant you just return the abstract class?
wanton delta
i would want to return the class's instance
dusky herald
Okay I get you
wanton delta
well the problem is i wouldnt be bale to do B b = new B().setTrue()
dusky herald
try <? extends A>?
wanton delta
only other way i could think of doing it is making setTrue() abstract and add it to all subclasses
wildcard ? doesnt work... tried
tiny dagger
? super A?
wanton delta
nope cant use wildcard in place of T

try t then
wanton delta
that method above is what i currently have, its just i cant return this

ashen stirrup
On the PlayerChatTabCompleteEvent, is event.getLastToken() the string before?
e.g /about <TAB>, would about be the last token?
ashen stirrup
Would event.getChatMessage() get about then?
wanton delta
conventions usually imply that last is always the last in an array, whereas previous would return the one before
i think youre looking for PlayerCommandPreProcessEvent
if you're trying to limit the commands players can see when they tab, use PlayerCommandSendEvent
hmm i could do java public A setTrue() { setBoolean(true) return this; } but that requires me to cast java B b = (B) new B().setTrue();

wanton delta
if you feel comfortable protocollib makes things 100x easier 😛
sturdy oar
oh wait what do you mean by inclusive or exclusive?
@boreal tiger it should not be longer than 5 , so ( byteLength <= 5)
boreal tiger
ah, I think its inclusive then
sturdy oar
oh that one , thank you.
wanton delta
np :D
ashen stirrup
Can you edit event.getTabCompletions()?
wanton delta
what is the event
PlayerCommandSendEvent you can use event.getCommands() and add/remove what you please
ashen stirrup
PlayerChatTabCompleteEvent
I want to check if the command before they press tab is /about
PlayerChatTabCompleteEvent
I was going to check the getChatMessage() and then getTabCompletions().clear();
wanton delta
use TabCompleteEvent then
dont use ChatTabCompleteEvent
wont fire when using a command
ashen stirrup
I'm using 1.8
wanton delta
imo its not worth supporting 1.8
ashen stirrup
Oh, why?
wanton delta
its unsupported, any issues you have with viarewind or 1.8 wont be supported here
amount off ppl that play 1.15 is far greater than 1.8

Wow what is that monstrosity, Martoph? lol
The server jar is not available unless locally installed, 902

I'm not sure if GitHub has a way to build using BuildTools (going to imagine not) though most people do things through Jenkins afaik
Though ideally you'd depend against the API which is hosted on the repository
narrow crypt

mhm I was representing armor upgrades as follows:
private final ImmutableMap<ItemStack, Upgrade<ItemStack>> upgrades = ImmutableMap.of(
new ItemStack(Material.LEATHER_CHESTPLATE), new Upgrade<>(new ItemStack(Material.CHAINMAIL_CHESTPLATE), 10),
new ItemStack(Material.CHAINMAIL_CHESTPLATE), new Upgrade<>(new ItemStack(Material.IRON_CHESTPLATE), 10),
new ItemStack(Material.IRON_CHESTPLATE), new Upgrade<>(new ItemStack(Material.DIAMOND_CHESTPLATE), 10)
);
However this approach does not allow me to check if the player is already in the last upgrade.
Any ideas how I could represent them?
I thought about implementing a directed weighted graph but was looking for other options before doing that
the reason why I was using a map is because It allowed me to easily look up the next upgrade
frigid ember
Would it not be easier to also then have a hashmap representing which armour upgrade they're on? (or just check what they're wearing?)
boreal tiger
thats what I'm doing
I check what they're wearing
and use that to lookup the next update
boreal tiger
np xD
mhm I think I can just change a bit what I was doing. if the key is not in the map I can just say its the latest upgrade 🤷♂️
they wont have access to other armor types so it should be fine

Guys is there any code to detect if player is on water, i mean, block.isLiquid() and block.getType() == Material.WATER is checking full block, not half blocks, you can stay on a kelp / seagrass / sea_pickle / coral being on water.
subtle blade
You would have to check for water as well as the waterlogged state
if (block.isLiquid() || (blockData instanceof Waterloggable && ((Waterloggable) blockData).isWaterlogged()))
(blockData being block.getData(), obviously)
boreal tiger
choco do you have any idea how I could solve the problem I mentioned :S?
silk bane
And in addition to what choco said, some blocks are waterlogged but don't have Waterloggable data
subtle blade
Any reason you're not using Materials here?
boreal tiger
oops forgot about that yeah I can just switch to material I think
subtle blade
some blocks are waterlogged but don't have Waterloggable data
You're right. The fuck?
Why isn't kelp waterloggable?
Oh is kelp literally just always in water?
silk bane
yeah
subtle blade
Well that's silly
silk bane
from what i can tell the best you can do with the API is maintain your own list of 'always waterlogged' materials
prisma wolf
for 1.15 block.getData() is deprecated 😒

Ok so after some research I decided to go with a dedicated server. Right now it looks like reliablesite.net is my best option. Any advice on other good/better hosts, or any bad experiences with reliablesite.net?

boreal tiger
@subtle blade would it be a bad idea to extend Upgrade and call it say NoFurtherUpgrades and point the last upgrade to that?

Now that's just silly

Don't think there's tab completion available for that through Bukkit, Thom
Might be a way to expose it in the API though
To be completely honest, the tab completion API should be slightly improved. I'll have to look into that
I might have an idea for it tbh
Y'know what? I'm going to take a stab at a PR right now to try and expose that a bit better

Importing the right Chest? There are three
You want org.bukkit.block.Chest, not org.bukkit.block.data.type.Chest or org.bukkit.material.Chest

When creating a namespacedkey, it works like new NamespacedKey(plugin, plugin.getDescription().getName()); correct?
In my case, there is error in the first argument which is plugin.
What can I do about it?
subtle blade
The plugin.getDescription().getName() can just be whatever unique identifier you want. This is your key
spring sapphire
I know, however, there is in the first argument
subtle blade
new NamespacedKey(plugin, "my_unique_key")
The first argument has to be an instance of your plugin's class. The one that extends JavaPlugin
spring sapphire
import org.bukkit.plugin.java.JavaPlugin;
subtle blade
Yea, whatever class extends that, it should be an instance of it
If you're in your main class, you would pass this for instance
spring sapphire
got it, thanks
bleak osprey
so no one knows? 😄

Not familiar enough with Bungee to answer that question but if you're using a fork of Spigot, you're better off asking them for support as they may make changes we're unaware of

@subtle blade I moved it out of the main class to the one where I handle events, there're a listener
However, plugin has the error
boreal tiger
@subtle blade guava's ImmutableMap doesn't support null values. should I add a static upgrade LAST_UPGRADE
and then I just compare if the value for a certain key is LAST_UPGRADE

Hi guys,
I am making custom to plugin to teleport players to other servers after logging in on auth server.
I am correctly registering output/input channels in onEnable (bungeecord:main).
@EventHandler(ignoreCancelled = true)
public void onLogin(LoginEvent event) {
Player player = event.getPlayer();
User user = this.userService.getUser(player);
String server = Auth.getInstance().getConfig().getString("servers_for_areas." + user.getTeam().getId());
Bukkit.getScheduler().runTaskLater(Auth.getInstance(), () -> BungeeUtils.sendPlayerToServer(player, server), 20);
}```public static void sendPlayerToServer(Player player, String server) {
ByteArrayDataOutput out = ByteStreams.newDataOutput();
out.writeUTF("Connect");
out.writeUTF(server);
Log.info("Sending " + player.getName() + " to server: " + server + ".");
player.sendPluginMessage(Auth.getInstance(), "bungeecord:main", out.toByteArray());
}```A player should be connected to server test-1, but nothing happens.
Does someone know what is wrong?
marble narwhal
@humble widget Did you register your plugin? With for example: this.getServer().getMessenger().registerOutgoingPluginChannel(this, "BungeeCord");
As listed here. https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/
humble widget
this.getServer().getMessenger().registerOutgoingPluginChannel(this, "bungeecord:main");```I believe the channel should be BungeeCord not bungeecord:main
humble widget
Channel names must be seperated with : on 1.13 or newer versions
Thus cannot use BungeeCord

hi!
is there way I can forbid interaction with player and impact with player avoiding events?

Why would you avoid events
Just use a
final Set<Player> unauthorized = Collections.newSetFromMap(new IdentityHashMap<>();```Put them in the set if they're not registered and then check that on events
and as soon as they register/login remove them
@narrow crypt beacuse you are saving the ItemStack object into the file

learn java is the way to do it

Guys how do I make path finding goals on an EntityPlayer
brisk mango
NMS
frigid ember
I knew that, but how
patent monolith
Oh, for like NPCs?
frigid ember
Yeah
frigid ember
bruh
patent monolith
Ahaha
remote sluice
hello, where download version 1.12 4.4.4???
patent monolith
Or maybe this for the minimum https://www.spigotmc.org/resources/citizens.13811/ @frigid ember
@remote sluice use buildtools https://www.spigotmc.org/wiki/buildtools/
remote sluice
1.12(top)
Code (version112 (Unknown Language)):
java -jar BuildTools.jar --rev 1.12
Will build a CraftBukkit and Spigot jar for 1.12
Change Log: Mojang | Stash | Jenkins
no link download
patent monolith
@remote sluice you need to follow the process described on the page
There isn't a convenient link to download the spigot 1.12 jar
You have to build the jar on your computer
spring sapphire
Perzan, can I use your help in something?
patent monolith
Sure, if I can help
spring sapphire
private NamespacedKey owner_key = new NamespacedKey(plugin, "Lock chest");
why is the plugin argument marked as an error?
"plugin can't be resolved as a variable"
patent monolith
Is owner_key in your plugin's main class?
There is no variable called plugin on there I bet
spring sapphire
Nope, but even modifying it to the main class doesn't make it work
patent monolith
You will need to have a variable of the type Plugin called plugin somewhere on the page
It also cannot be null
brisk mango
@spring sapphire I suggest you to learn java
also plugin will be null if you do it like this
patent monolith
What does the class's constructor look like?
spring sapphire
Shouldn't it take the Plugin from library JavaPlugin of bukkit?
brisk mango
Wdym
patent monolith
For that argument, you need to reference your plugin's instance
We can static abuse if you want lol
brisk mango
public final class Main extends JavaPlugin {
@Override public void onEnable() { }
}
public class MyClass {
private final Main plugin;
public MyClass(Main plugin) { this.plugin = plugin; }
private NameSpacedKey owner_key;
void myMethod() {
owner_key = new NamespacedKey(plugin, "Lock Chest");
}
}
No never static abuse
Should always use dep inj for main instance
not singletons
patent monolith
Use that layout ^ @spring sapphire
brisk mango
Dep inj is more flexible/testable
patent monolith
I was thinking JavaPlugin.getInstance(<your plugin main class>.class)
brisk mango
No that is wrong lol
patent monolith
Lol quick n dirty, but not good practice
vernal spruce
you also have JavaPlugin.getPlugin(class);
remote sluice
java -jar BuildTools.jar --rev 1.12 in start.bat no good 😦
vernal spruce
didnt see any difference between that and injection yet
vernal spruce
isnt buildtools used with gitbash?
remote sluice
last version from 1.12 spigot
patent monolith
Try putting @pause on the last line of your batch file
Run it again and see what it says
spring sapphire
@brisk mango Do I have to use the namespacedkey on the Main Class?
brisk mango
no
remote sluice
i need the latest version 1.12! Thanks!
remote sluice
no understand...........
remote sluice
please give me comand for start.bat
remote sluice
Please do not run in a path with special characters!
C:\Users\Ionut\Desktop\Folder nou (2)>PAUSE
Press any key to continue . . .
brisk mango
it says it lol
spring sapphire
I removed the inner class.
how to paste code here?
private final Events plugin;
public Events(Events plugin) { this.plugin = plugin; }
private NamespacedKey owner_key = new NamespacedKey(plugin, "Locking Chests");
Same error.
rotund prism
@brisk mango
but I should register all events and cancel events those are not a chat command event, ain't it?
that's too much work for many events
Did I understand you right?
agile rock
If im logging into my mongodb whenever someone breaks a block, should I make that async ex: new Thread(() -> { databaseApi.incOresMined(databaseApi.getSimplePlayerByUUID(event.getPlayer().getUniqueId().toString())); }).start();
narrow crypt
so im saving itemstacks to my yaml but after 20 minutes they are turned to air in the config, no events happened in the meantime with the plugin:
loot:
kist1:
'4':
==: org.bukkit.inventory.ItemStack
v: 2230
type: AIR
amount: 0
'10':
==: org.bukkit.inventory.ItemStack
v: 2230
type: AIR
amount: 0
'11':

'16':

PlayerInteractEvent
narrow crypt
i have declared api-version: 1.15
at first they just are noted correctly
but they just change out of nowhere
anybody an idea how this is possible?
patent monolith
@spring sapphire assign the owner_key inside the constructor
brisk mango
@patent monolith no
You can't assign it inside the constructor
since it takes the plugin variable
while that's being initialised in the constructor
that's why there's a method for it
spring sapphire
public class MyClass {
private final Events plugin;
public MyClass(Events plugin) { this.plugin = plugin; }
private NamespacedKey owner_key;
void myMethod() {
owner_key = new NamespacedKey(plugin, "Lock Chest");
}
}}
@narrow crypt I told you how to do it so stop asking again
yes, like this
What
why do you have inner class
narrow crypt
im asking for another method to do it
brisk mango
``
public class Events implements Listener {
public class MyClass {
``
frigid ember
how do I use color codes in spigot.yml? When I try to use & it crashes my server with this message -https://hastebin.com/uwahogebep.sql (I changed unknows command)
brisk mango
@narrow crypt There's no other method if you're saving it into file
spring sapphire
Should be like this?
private final Events plugin;
public Events(Events plugin) { this.plugin = plugin; }
private NamespacedKey owner_key;
void myMethod() {
owner_key = new NamespacedKey(plugin, "Lock Chest");
}
````Well imma hop on my pc
brisk mango
I don't think that can be done Async but you can try it @agile rock
narrow crypt
why doesnt anybody do it like that then .. :(
brisk mango
What is the error
spring sapphire
Constructor NamespacedKey is not defined
agile rock
@brisk mango I was told to make all database calls async so it dosent disturb the main thread or something like that
patent monolith
On my phone in bed rn lol
brisk mango
Well it's not defined then?
patent monolith
Ill hop on my pc
rigid nacelle
@brisk mango I was told to make all database calls async so it dosent disturd the main thread or something like that
@agile rock You should, yes.
brisk mango
Oh hello my old friend
rigid nacelle
Helloo.
brisk mango
are we going to take this discord over yes?
rigid nacelle
(:
agile rock
Ok, is new Thread(() -> {// database call}).start(); a proper way to do it?
brisk mango
Creating threads is outdated but yes you can
patent monolith
Try bukkitrunnable async
agile rock
D:
brisk mango
use BukkitScheduler/ExecutorService
spring sapphire
Eclipse is suggesting changing plugin to String to fix it
brisk mango
lol
rigid nacelle
I personally like CompletableFuture.runAsync(...). Depending on what I'm doing, CompletableFuture.supplyAsync(...) could come in handy too.
spring sapphire
However, Namespacedkey doesn't take a string in the first argument
It takes plugin
brisk mango
That means, dont use eclipse
patent monolith
Well, whatever you use, make sure you make it so it wont run if your plugin is disabled
spring sapphire
private final Events plugin;
public Events(Events plugin) { this.plugin = plugin;
owner_key = new NamespacedKey(plugin, "Locking Chests");
}
Is there anything wrong with that?
Despite the last }
rigid nacelle
Temedy, he's using the one passed.
Not this.plugin so that's fine.
It would've been initialized anyways since he initializes it above the owner_key field initialization.
patent monolith
Where is owner_key
brisk mango
private final Main plugin;
public Events(Main plugin) {
this.plugin = plugin;
owner_key = new NamespacedKey(plugin, "Locking Chests");
}
But doing this can cause null pointers
rigid nacelle
If the plugin object passed is null, sure.
I'm not sure about the whole situation though. What is the actual error? I haven't seen it.
patent monolith
In that light, I suggest doing Objects.requireNonNull(plugin, "plugin")
For other params in the future as well
brisk mango
lol
patent monolith
k welp, im on my pc now
spring sapphire
temedy, still same
private final Events plugin;
public Events(Events plugin) { this.plugin = plugin;
owner_key = new NamespacedKey(plugin, "Locking Chests");
}
private NamespacedKey owner_key;}```What same?
rigid nacelle
One thing that comes with the spigot API is Guava and I absolutely love it.
patent monolith
gson and yaml are also nice
spring sapphire
The constructor NamespacedKey is undefined
suggesting changing plugin to String which doesn't make sense
patent monolith
I just realized
rigid nacelle
You could be using the 1.15.2 dep and it tells you to use plugin, string but running it on for example 1.8.8 would be string iirc.
patent monolith
you are referencing Events as a plugin....
in the parameter
but its that own class
rigid nacelle
Lmao..
patent monolith
welp
agile rock
public void onPlayerJoin(PlayerJoinEvent event) {
// Checks if player is new, if so it will create a new SimplePlayer and log the player into the database
if(!event.getPlayer().hasPlayedBefore() || (databaseApi.getSimplePlayerByUUID(event.getPlayer().getUniqueId().toString()) == null)) {
plugin.getScheduler().runTaskAsynchronously(plugin, new Runnable() {
@Override
public void run() {
databaseApi.createSimplePlayer(event.getPlayer().getUniqueId().toString(), LocalDateTime.now().toString(), System.currentTimeMillis());
}
});
}
}``` Would this be the proper use of BukkitScheduler?i had to paste this into my ide to notice that
spring sapphire
private final ChestLock plugin;
public Events(ChestLock plugin) { this.plugin = plugin;
owner_key = new NamespacedKey(plugin, "Locking Chests");
}```So it should be like this
considering ChestLock is the main
correct?
patent monolith
yeah
remote sluice
https://www.youtube.com/watch?v=QdV-3OtXcPY
omg is very hard for download a version.......
i finish, tahnks
remote sluice
I think I did :))
agile rock
@rigid nacelle @brisk mango Could u guys take a look at how I used the bukkitscheduler above please?
patent monolith
new BukkitRunnable() {
@Override
public void run() {
// your code
}
}.runTaskAsynchronously(plugin);
oh, is that the same as plugin.getScheduler().runTaskAsynchronously(plugin, new Runnable() { @Override public void run() { databaseApi.createSimplePlayer(event.getPlayer().getUniqueId().toString(), LocalDateTime.now().toString(), System.currentTimeMillis()); } });
patent monolith
yeah
agile rock
gotcha
patent monolith
should work either way
agile rock
@brisk mango Would you recommend that I use the one I put above^
brisk mango
?
patent monolith
to run the bukkit runnable task?
patent monolith
ah
spring sapphire
Perzan, I can't my events handler the plugin folder?
spring sapphire
Because after I added ```public class EventsChest implements Listener {
private final ChestLock plugin;
public EventsChest(ChestLock plugin) { this.plugin = plugin;
owner_key = new NamespacedKey(plugin, "Locking Chests");
}``` to my Events folder
the getServer().getPluginManager().registerEvents(new EventsChest(), this); gave an error in the main
patent monolith
new EventsChest(this)
if you look at the constructor definition in the EventsChest class, it takes an instance of your plugin
spring sapphire
public void onEnable() { getServer().getPluginManager().registerEvents(new EventsChest(this), this); }
Now, it's working
patent monolith
using this is like a special variable in java that references the instance that your code is in
cool
spring sapphire
So without removing this, the argument is getting all of the instances ?
frigid ember
Depending on the use case @brisk mango it is acceptable to use either one
spring sapphire
using^
brisk mango
No it's not
pure pasture
How can you get which dealt damage?
brisk mango
It's not getting any
pure pasture
which entity*
