I guess I'll install the plugin you sent on a server to see it in action. Could you elaborate what checks you are talking about?
I'd have expected that I can simply do
"Description of the field"
<player input>
or for lists:
"Description of the list"
<player input>
<player input>
<player input>
and I'd just collect all inputs of all pages and seperate by linebreaks.
Unless I take it one step further and put all fields in one book (one field per page, unless it's a list)

I'm pretty sure this means that you don't have your command in the plugin.yml

With book you would need to implement a bunch of checks. Like if they closed it early, put invalid inputs. Conversation api you can validate and if invalid data is there go back and say so. Also you can specify a keyword to end the conversation early and just toss the data away
Also with conversation api you can add explanations etc
As you go through the settings
Which you decide is ultimately up to you of course. I just think using a book is not the best for this
flint coyote
Does the conversation api utilize that clickable text in chat? I don't remember how it's called.

idk i never used vscode, just better than IntelliJ idea

You can use chat components with it if i recall

Of course. I'll give both a look and test what feels better for me and maybe ask a friend or 2

Let me try it in bash, iirc i got the same error the other day but didnt have a chance to look back at it as i had to leave for work.

buildtools is doing that automatically
zenith crescent
Where would i do that at?
wet breach
Try clearing buildtools directory
But issue seems to be with maven since it doesnt get to the actual building phase.

Generally nuking everything but the buildtools jar is my first step
Second step is panic
wet breach
Lol
sullen marlin
your java is kind of old (2021) maybe try updating it?

That's very rude. Maybe you're old >:(
zenith crescent
lol, whats the default path for buildtools? I cant find it
young knoll
MD and Java can both be old
sullen marlin
It's where you downloaded it, D:/Downloads
zenith crescent
that would make sense lol
Alright, give me a minute my downloads is still on a HDD so it takes forever
Alright, so iv deleted all the files i think are build tools in my downloads directory, but im still getting the same error.
https://i.imgur.com/ugLLZRy.png iv deleted these 5, these are the ones re generated
wet breach
Try moving buildtools jar to its own directory
Next step would be to install maven and there is plenty of guides in how to do that

@ivory sleet have you injected a channel handler (netty) in spigot before?
Im currently a bit lost. I got a duplex handler for outgoing packets working
but i cant seem to get incoming packets to work...

Ah i just noticed the decouple method makes no sense. I need to remove my channel names ofc
lost matrix
But when testing both duplex handler only listen to outgoing packets...
ivory sleet
Get the pipeline and invoke addBefore that’s how its supposed to be done
torn shuttle
so yeah the only way to guarantee no overriding behaviors seems to be through lobotomizing the AI for as long as you don't want to get overriden
lost matrix
Get the pipeline and invoke addBefore that’s how its supposed to be done
Thats what i thought... are there two connections for incoming and outgoing?
Wait im adding both after the default encoder
And both the incoming and outgoing encoder name is just "packet_handler" if i interpreted that right
ivory sleet
yeah
the base name should be just that
Yea maybe try to use addBefore instead, also aren’t you having the same if statement twice?
Or am I just seeing things
lost matrix
One is for encoder name and the other for decoder.
In the case of bukkit, its the same
ivory sleet
Ah I see
torn shuttle
I just don't understand what mojang is thinking here
lost matrix
Hm and that makes both handlers be inserted after the default "packet_handler"
How is this even supposed to differentiate between incoming and outgoing packets?
torn shuttle
they have a brain system, why is the brain not managing activities
why do they have ai classes for individual mob types but still hold key parts of the AI logic in entity classes
how come brains are simultaneously stupidly in-depth intricate systems but also don't actually manage important aspects of behavior
ivory sleet
and I think u can use the same duplex handler for incoming and outgoing
torn shuttle
how come entities go back to idle from combat after every single hit and idle manages part but not all of the combat pathfinding
did the guy that came up with the module system for brains get paid by the class he wrote?
torn shuttle
no
after every single hit they do they enter a cooldown state
for the duration they are in idle
even if they keep following you around
because following is idle
young knoll
So when they hit you they revert to idle
torn shuttle
attack seems to be strictly the tick they hit you on except it also has some pathfinding logic somehow and also it's a per-entity implementation because obviously no two mobs in minecraft hit you quite the same way
states are for losers and priorities are for nerds, the brains use both and neither work in way that makes sense
all the priorities seem to be the same and the states will flip in ways that are hardcoded to each entity
young knoll
I see why they haven’t updated the old entities
torn shuttle
let me bring up the wisdom of the ancients if I can find it
It’s important to remember that when you start from scratch there is absolutely no reason to believe that you are going to do a better job than you did the first time.

Yeah already on that track

So it may also terminate?
Hmm, yea idk much more but it wouldn’t be out of scope to think that it stops delegation
ivory sleet
and I think u can use the same duplex handler for incoming and outgoing
also this (maybe?)
(:
lost matrix
also this (maybe?)
Yeah i found the problem. I appended my handlers after
[timeout, splitter, decompress, decoder, protocol_lib_inbound_interceptor, prepender, compress, encoder, protocol_lib_wire_packet_encoder, pe-encoder-grimac, packet_handler, DefaultChannelPipeline$TailContext#0]
the packet_handler which does not forward incoming packets. So at least the inbound listener needs to be
injected before the packet_handler
young knoll
Oh look it’s protocollib and grimac
ivory sleet
🥲
young knoll
Protocollib twice for good measure
lost matrix
also this (maybe?)
Yeah ive used one duplex handler now and it works like a charm.
https://gist.github.com/Flo0/5aa8849af8c50dfa365042d4fe52160c
Just had to prepend it to the packet_handler and implement both write and read
for my duplex handler. 👍

Ah
So first of all I wasn’t using rev for build tools
So it was probably building 1.19.3
But also yes my Pom was just wrong
Since you put the version in the special source part twice
I changed it in one part but not in the other
Alright I’ll let you know if it builds

Create a property in your pom and insert it using {}

just make a durability pdc tag
ivory sleet
However you can make an item lose durability half of the times its supposed to lose durability, that way the item seems twice as durable
Or go with the op imajin strategy
(And then scale with actual durability)
trim lake
Ye, the pdc tag sounds like solution. But still will need (not rly) to edit damge of item to show durability for player.
trim lake
I can make item unbreakable and then just remove from inventory if pdc tag od durability is 0

Unbreakable removes the durability bar
ivory sleet
Or you make the durability of the item the same percentage based of ur pdc durability
That way the scale remains untouched

thanks guys for help. I was looking for nbt tag or just something I can change. I know damage can be changed but thats not enough.

Yeah I’m suggesting a robust and easy design by switching out an implementation detail
Map<String,Instant> map = …;
//set cooldown
String string, Duration cooldown
map.put(string, Instant.now().plus(cooldown))
//has cooldown
String string
var cooldown = map.get(string)
//null check
return Instant.now().isBefore(cooldown)
//remove cooldown
String string
return map.get(string)
//get cooldown
String string
var cooldown = map.get(string)
//null check
if has cooldown
return Duration.between(Instant.now(),cooldown)
else
return Duration.ZERO

when doing cooldowns, it's way easier to create one cooldown class, instead of throwing the logic into the actual listeners / commands - then you can reuse it everytime.

Is there any resource on how to preverse comments when using Configurations in Bungee plugins (on save)?

desert loom
The problem is that your if statement here does not check if the sender is on a cooldown.
if (cooldown.get(sender.getName()) > System.currentTimeMillis())
To check if a sender is on cooldown, check if the result of sender-cooldown - now is > 0
final long now = System.currentTimeMillis();
final long remaining = cooldowns.getOrDefault(sender, now) - now;
if (remaining > 0) {
// sender on cooldown
return;
}
// Do code stuff
cooldowns.put(sender, now + 10_000); // put sender on a 10 second cooldown
Use getOrDefault instead of get to avoid an NPE when unboxing the boxed primitive from the map
Also, you should prefer early returning instead of nesting your if statements.

well but you cannot know how long this sound takes. spigot can only tell the client "play sound XYZ" - that sound could be 2 seconds long, or 27 minutes - depending on the resource pack, etc.
You will HAVE to add a delay yourself
what you can however do is to stop the existing, already playing sound for players
Player#stopSound or sth
anyway, you will need a loop with a delay

for playing a sound at a specific location

yeah that's not the problem, they want to play the sound "continuosly"
or however that's written
wet breach
they can do that but the issue is they are going to have to measure the time length of the sound as that isn't provided
wet breach
and then once they know how long the sound is, they can just make a repeating task with that as a delay

for my JukeboxPlus plugin, I just have a config file where people can enter the amount of seconds that their songs take, in case they use custom songs

well you can force players to use the server resource pack, and if that includes all the sounds they need, I think one would be fine

What's your code look like now?
you're missing a return in the if statement.
in the block*
if (remaining > 0) {
ProxyServer.getInstance().getLogger().info("Sixth condition!");
String message = Everywhere.getColors(config.getString("AntiSpam.message"));
message = Everywhere.Replace(message, "{cooldown}", String.valueOf(intCooldown));
event.setCancelled(true);
sender.sendMessage(message);
// missing a return here
}
you are constantly refreshing the player's cooldown whenever they type the command without that return statement
if that's your problem, that return should fix it.
eternal oxide
final long remaining = cooldown.getOrDefault(sender, now) - now; is returning the default
now
the one you provide

your if test is also invalid
once they have a cooldown if (remaining > 0) { is ALWAYS going to be true
you need if (remaining - now > 0) {

you are adding in the map now + cooldown

ok and how i can made it to not going higher? i mean the Y
young knoll
Make them build the text in pixel art with blocks
icy beacon
TRUE
icy beacon
ok and how i can made it to not going higher? i mean the Y
elaborate plz
young knoll
ok and how i can made it to not going higher? i mean the Y
You don’t want them to move up at all?
.setY(0)
sage patio
yea
fresh timber
wait so ehm
icy beacon
^
young knoll
You can’t chain that though
sage patio
good, thanks
fresh timber
can I make an itemstack with like 100 items in it?
young knoll
Yes
fresh timber
k
icy beacon
i think you can make as many items as you want, but at SOME point they will get clamped to [-128, 127]
not sure when exactly
fresh timber
im using for compressing blocks for a mining server
so like I make an itemstack and add items to it through then at end give player all the items
icy beacon
i recall having a bug where my item amount would get to -127 or -128 idr
so i just deduced that they get clamped to this interval at some point

<https://stackoverflow.com/questions/22118116/how-to-run-a-particular-task-every...
simple question about this how can i test it if it works?
eternal oxide
sysout the period you are scheduling for
you can use that to calculate when it will happen
wary mauve
@eternal oxide this workload distribution you sent feels quite a bit advanced for me. I'm trying to piece it together but I'm still a little confused
eternal oxide
read it a few times. it's a good thing to get to grips with. Yes it is advanced
wary mauve
So I get the concept of the linear processing I think. It fills up the remaining time in the tick with what you want to do, but doesnt delay the tick.
wary mauve
So what if I wanted to generate a chunk, which I think would take 150ms with the generator Im using
No one's on the server when Im generating this btw
eternal oxide
could you split up the generation? Are you actually creatign a proper chunk generator or a block populator?
wary mauve
Im using a plugin that is a generator. I am pretty sure its a real chunk generator
eternal oxide
why is it so slow?
wary mauve
dont know
But it looks cool
Would the workload distribution 100% fix the issue of why the server freezes when this bit of code is in a runTaskTimer task?
eternal oxide
try adding a longer delay between tasks. Give the server some time to catch up
wary mauve
when its in a tasktimer, it doesnt finish the generateChunkSquare method. It's fine when its not inside a task
eternal oxide
If your task takes 150ms to run you should give at least 3 ticks between tasks
wary mauve
It never gets to that point
eternal oxide
if each chunk is 150ms then it needs 3 ticks between each chunk gen
wary mauve
so I need to break up the loops into an individual task per chunk?
wary mauve
can I have a task inside a task?
eternal oxide
you'd do better pushing your tasks to a queue
zenith crescent
Any suggestions for an API to use for player heads? Thats not Headdatabase, or is it worth just buying it?
eternal oxide
which is what the workdistro is really for
only process one chunk/task per 4 ticks

i tried starting it and the println works just fine but i really don't understand why it doesn't start the check
wary mauve
only process one chunk/task per 4 ticks
right. This is gonna take me forever to figure out. why did I have to pick something so complicated for my plugin lol. I think Im starting to realize why Ive never seen a server do this
eternal oxide
🙂
sage patio
can i made this particle to stay at where whey got spawned?
event.getPlayer().spawnParticle(Particle.CLOUD, event.getPlayer().getLocation(), 1, 0.1, 0.1, 0.1);
eternal oxide
Do you mean it moves, or are you wantign it permanently in place?
wary mauve
🙂
Do I even need to have it in a task? If there isn't a task, I could just do it all in one tick. The server would be on one tick for tens of minutes if I wanted to generate a lot (maybe even hours). As long as the world is saving, wouldn't it be fine?

No the watchdog will think the server has crashed
sage patio
You can set the speed value to 0
||is it supported on 1.12.2?||
wary mauve
No the watchdog will think the server has crashed
the generator plugin I use suppresses watchdog
young knoll
For most particles
eternal oxide
the generator plugin I use suppresses watchdog
then you could just hammer it all out, I guess
sage patio
double extra is the speed
yes it works, thanks.
wary mauve
Last time I tried doing a lot, it crashed after like 90*81 chunks and the memory was going up consistently. If I save it the world, will it clear that cache?
eternal oxide
you could unload the chunks after generating/dsaving
sage patio
For most particles
also they are despawnin too fast, can i change that too?
eternal oxide
particles have a fixed animation speed
sage patio
and i can't change them?
eternal oxide
no
sage patio
ok then

hello i have a quick question for you guys how do i make a bow be able to damage endermen i have been testing a few stuff but cant figure it out this is my code so far
public void onPlayerInteract(PlayerInteractEvent e) {
Player p = e.getPlayer();
if (e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK || e.getAction() == Action.LEFT_CLICK_BLOCK || e.getAction() == Action.LEFT_CLICK_AIR) {
ItemStack item = p.getInventory().getItemInMainHand();
if (item.getType() == Material.BOW && item.hasItemMeta() && item.getItemMeta().hasDisplayName() && item.getItemMeta().getDisplayName().equals(ChatColor.GOLD + "Terminator")) {
if (cooldownMap.containsKey(p)) {
long lastShotTime = cooldownMap.get(p);
if (System.currentTimeMillis() - lastShotTime < cooldownTime) {
plugin.getLogger().log(java.util.logging.Level.INFO, "Terminator cooldown " + p);
e.setCancelled(true);
return;
}
}
p.setItemInHand(item);
p.launchProjectile(Arrow.class);
cooldownMap.put(p, System.currentTimeMillis());
}
}
}```im not sure if this run, but in theory should
Calendar with = Calendar.getInstance();
Map<Integer, Integer> dayToDelay = new HashMap<Integer, Integer>();
dayToDelay.put(Calendar.FRIDAY, 2);
dayToDelay.put(Calendar.SATURDAY, 1);
dayToDelay.put(Calendar.SUNDAY, 0);
dayToDelay.put(Calendar.MONDAY, 6);
dayToDelay.put(Calendar.TUESDAY, 5);
dayToDelay.put(Calendar.WEDNESDAY, 4);
dayToDelay.put(Calendar.THURSDAY, 3);
int dayOfWeek = with.get(DAY_OF_WEEK);
int delayInDays = dayToDelay.get(dayOfWeek);
System.out.println("Started Event");
ScheduledExecutorService service = Executors.newSingleThreadScheduledExecutor();
service.scheduleAtFixedRate(() -> {
try {
checkUpdate();
} catch (ParseException e) {
throw new RuntimeException(e);
}
}, delayInDays, 7, TimeUnit.DAYS);
I wanted to ask you only for be sure
zenith crescent
Any suggestions for API to get custom heads?
ivory sleet
Can’t you just use spigot stuff
storm isle
i would recommend this one
https://github.com/Arcaniax-Development/HeadDatabase-API
zenith crescent
I think you can for player heads, but im not sure about custom ones
tender shard
don't tell me this compiles
Ofc it does
ivory sleet
Or r u looking for a texture index api like that one^
zenith crescent
I guess like that, is it worth buying?
tender shard
Any suggestions for API to get custom heads?
Use PlayerProfiles
zenith crescent
Ok, ill try it again. I thought last time it wouldnt load bc i didnt have the plugin
ivory sleet
There is probably a free variant on the market just as good, and ftr the api does not work without the plugin iirc
young knoll
If you are on modern spigot there is an API for custom heads
By modern I mean like
1.17? 1.18?
zenith crescent
yeah im using 1.19.3
young knoll
You got the PlayerProfile API then
ivory sleet
I think he is looking for an api that indexes textures based of searches also?
young knoll
Ah
tender shard
https://blog.jeff-media.com/creating-custom-heads-in-spigot-1-18-1/ ill just drop this here anyway just in case
ivory sleet
Not entirely sure still what they really need 😅
zenith crescent
Im looking to use this head, https://minecraft-heads.com/custom-heads/humans/28230-poseidon
young knoll
I generally prefer using a UUID made from the string
But yeah jeffs tutorial will work
storm isle
hello i have a quick question for you guys how do i make a bow be able to damage...
also can someone help me with this
zenith crescent
Ok thank you
sterile token
also can someone help me with this
You must be pacient, if you want to your dont get lost. You should create a thread and wait until someone answer it
Because all people here are volunteers none getting paid for instant help
storm isle
i know im not trying to be rude i was just asking
young knoll
Hmm
sterile token
oh my bad
young knoll
Idk if cancelling the EntityTeleportEvent would be enough
storm isle
wont that like cancel all the endermans teleports?
tender shard
I generally prefer using a UUID made from the string
The reason why i reuse the same UUID is because creating a new PlayerProfile will result in a new file getting created
young knoll
Ah
tender shard
And i didnt want to have thousands of useless files
tender shard
At least it did when i wrote that blog post. Maybe its different now, idk
wary mauve
@eternal oxide the memory goes up slowly even when I save the world. This will crash my server eventually. How do I prevent this? Im generating chunks btw
wary mauve
what's gc?
tender shard
Garbage collection
wary mauve
but look at the slope of the lowest point. That's the issue
tender shard
Yeah i see. Did it crash anytime, though?
tender shard
Wait until/whether it actually crashes
tender shard
Hm do you know where its coming from?
young knoll
They are doing a bunch of worldgen stuff
wary mauve
Yes only one thing is happening. Im generating chunks. This gets called in different areas
tender shard
Are you returning a new instance of your chunk generator instead of reusing the existing instance?
wary mauve
No. It's all in one tick. Not sure if that matters.
That's promising:
It's on area 41/100. Last time it crashed at 89
sterile token
That's promising:
Getting chucks is an intensive operation
sterile token
Are you trying to load worlds?
wary mauve
It's all in one world
sterile token
In case of loading worlds you have to use a work distribuitor**
wary mauve
I probably should for this too, but if it works the way it is, I don't want to figure that out
sterile token

Work distribuitors are used to fix the chunks generating lag, so then your server dont freeze or make tps going really down
wary mauve
Im fine with the tps being 0. It's pregenerating areas and no one would be on when this happens
