after working on this NBT parser, just realizing, I should have just worked backwards on packet to determine the length of the nbt data
frigid ember
can someone help me listen to login packets
inland oxide
why
inland oxide
for?
frigid ember
why for?
in here no login packets are received
i inject players on join
and uninject on quit
just I want to listen to handshaking packets for example
inland oxide
not really sure what you mean by injection?
frigid ember
do you know how to or not
inland oxide
no need to be rood
frigid ember
sorry no offense but some people ask why, but dont know yk
so it doesn't make sense to ask why
frigid ember
tell me
inland oxide
hooking login packet
frigid ember
how
inland oxide
with netty
or in proxy in bungeecord
or you can just display the packets using the logging
inland oxide
never found the third to be particularly useful, but it involves writing a custom log config for log4j
frigid ember
how does protocollib do it
inland oxide
mostly sending packets
but I think there is a way to listen as well
but that might be with netty
frigid ember
you are confusing me
inland oxide
so this is not just for investigative, but actually runtime?
frigid ember
you do know or not
inland oxide
know what?
inland oxide
not off the top of my head
frigid ember
ok
inland oxide
I recommend you do your research
inland oxide
I've done packet listening by modifying bungeecord
and with the log method
but not with protocol lib as a listener
frigid ember
im not using protocollib
inland oxide
so directly with nms?
frigid ember
yea
inland oxide
not sure.
i know there are lots of NMS for packet generation, never looked much into the part on login
assume there is a netty handler somewhere in NMS
theres a video
frigid ember
BRuh
i already did packet listening
I said all I want is login packets
Handshaking packets
if u checked my code
.
hi @frigid ember

inland oxide
I'm watching the video, to get context
frigid ember
the video does not even cover login packets
let me send u what i mean
for context
inland oxide
No, but it explains concepts rather than tell you specific answers
frigid ember
What concepts
inland oxide
you know, you are approaching this all wrong
frigid ember
write is all packets sent from server
inland oxide
you need to understand netty first
inland oxide
ok, so are you even getting login packets/
frigid ember
handshaking packets are sent from the client
inland oxide
are you even getting packets
inland oxide
ok, good, so sound's like the handshaking is different than the main channel
native shore
Just ask ur question @frigid ember
inland oxide
when are you injecting the packet listener, in onjoin?
frigid ember
tinyprotocol they listen to it, im still trying to look through the code
yea
I don't inject PlayerLoginEvent as some versions removed it
or renamed it idk
inland oxide
so that won't really work if that happens after the handshaking
frigid ember
ok
inland oxide
and you want the handshaking packets, not the join one, right?
frigid ember
ima test with playerloginevent
yes
like ProtocolSet
to check protocolversion
for example
ima try debugging
what packets i receive
inland oxide
it looks promising
frigid ember
to inject i need a player object so i cant inject on PrePlayerLoginEvent
or AsyncPrePlayerLoginEvent

if you inject from PlayerPreLoginEvent or AsyncPlayerPreLoginEvent do you get more packets?
frigid ember
i cant inject
i can only inject a player object
give me a sec
hm
im probs injecting too late ur right
hm
inland oxide
i'm not an expert on this player injection stuff either
but seems like there would be no player object that that point anyway, right?
inland oxide
something else like a pending connection or something
frigid ember
so its not only the handshakings missing
its not morla for first packets to be those
So I am injecting too late
give me a sec
frigid ember
thats not the point
some packets are missing
but the main goal was to get protocol version
1.7 added a field for players for it, but 1.8+ removed it
inland oxide
funny how goals change
frigid ember
some other packets are missing
inland oxide
what version are you targeting?
frigid ember
all
inland oxide
ok
frigid ember
1.7.10->1.15.2
i already handled the multi support part
dw
maybe the fact that im injecting asynchronously
is the reason
people recommended me to do so
hm
ima test
xd
no
its not the fact i inject too late
protocollib also injects with same event
so its prob that its async

Hi, I want to modify the "durability" enchant values from the server. Is it possibile? Overriding it.
That cause I distributed too many over enchanted armors with durability and these are literally indestructible.
I want to rebalance the PvP on my server.
inland oxide
depends on how @sage kraken
if you mean modify durability for all items in player inventories and in containers on specific worlds, it can be a time consuming process
but, could be done on the fly
did you look and see if there were any plugins that already set limits?
sage kraken
if you mean modify durability for all items in player inventories and in containers on specific worlds, it can be a time consuming process
@inland oxide is it possibile to edit to modify consuming process of armors?
looking on spigot there are custom enchant plugins only :\
inland oxide
yeh, I was thinking more of a plugin that would change an items durability when held by a player if is was not within set bounds
it's not that hard to program, so wouldn't be surprised if there were plugins that did it
sage kraken
I made a mistake adding armor with high durability values
I searched "edit amor consuming process plugin spigot" on Google but nothing
inland oxide
i was thinking more of the Confiscate plugin, whether it has ability to change item durability and leave it in place
frigid ember
i keep getting this error

idk why
i tried 5 times

could always look at ServerConnection and HandshakeListener to see how it's handled my mojang in NMS for the handshaking
frigid ember
i dont wanna look at such large stuff

I think might start at NetworkManager
then get the ServerConnection

looking at the NMS code does help to understand how it's setup
I'll cycle back on this later, but do need to finish this NBT parser thingy for the new 1.16 login packet

Is there a way to optimize lavacasts with a plugin?
native shore
why shouldnt it be valid?
keen compass
@sturdy oar you can have a list contain a list which is no different then having a hashmap contain a hashmap
kind crow
Can I stop water/lava from floating to other blocks if the tps gets too low and resume if the tps recovers?
bronze marten
@sturdy oar isnt that just an abstract class which you are implementing using an anonymous class, then just getting the method .getType() on it?
abstract class just doesnt have any methods to implement, thats why the {}
keen compass
there is nbt data or metadata associated with lava that you probably could manipulate to increase performance
https://minecraft.gamepedia.com/Lava
@kind crow
only other way would be to cancel the events for lava/water flow
keen compass
the more blocks there are with lava/water the less performant it becomes in cancelling the events and therefore would probably need to resort to nms or manipulating nbt data anyways
for instance, you could turn the water into source blocks temporarily which makes them not flow
kind crow
But the tps decreases when there are a lot of floating water/lava already. I don't think turning it in source blocks solves that
keen compass
TPS shouldn't decrease because of lots of water not flowing, think you are confusing FPS with TPS
kind crow
To replace a lot of water blocks you need a lot of resources I think
keen compass
you wouldn't need to replace them, just change their nbt data
kind crow
Would it be in a loop of some kind?
keen compass
well, you would need something to determine when to do that or undo it
kind crow
Or can I change general nbt tqgs on all of the blocks at once?
keen compass
so there would have to be a loop of some kind, what kind I am not sure depends how you decide to implement it
well you could just listen for flowing events
and then just use those events to change those blocks
kind crow
It would brobably take a lot of resources as well
keen compass
not really o.O
kind crow
and then just use those events to change those blocks
@keen compass this is a good idea I think
keen compass
only thing you are going to have to do though is keep track of the blocks you changed and what their data was before you changed them so you can change them back
kind crow
If I'm listening to flowing events already why don't I just cancel them without changing anything?
keen compass
because if there is a lot of water flowing in the chunks loaded or lava, then the more there is the more events you end up cancelling and then eventually the purpose behind it becomes pointless because you start overwhelming the server with continuously cancelling the events. This is assuming you just do nothing but cancel the events. You could cancel the event after you modify the blocks so that they don't cause another event to be raised.
kind crow
That means I will have to save every flowing block data each time tps goes back and do it until lavacast is ready
keen compass
I don't see the problem in that
frigid ember
How can i check if a player had a specific name, example: if someone has the name CoolBoy then he can only execute a command, and if other people try the command it says "Only CoolBoy can do this"
cloud crater
Yes @frigid ember
keen compass
why not use their UUID's to do your checking? o.O
kind crow
Ok, I'll try that, thanks @keen compass
keen compass
the way you could save the data and keep it compact is make a modified version of schematics @kind crow
could look at worldedit how they create/save/load schematics. And just make a modified version for your purposes and thus you have a compact way to temporarily store your data π
then you could leverage memory mapping which would make it save and load super fast if it was done right
frigid ember
Yeah name or UUID, but how can i do that?
keen compass

keen compass
what do you mean hot reload?
are you talking about replacing the jar while the server is running?
keen compass
something like JRebel can do that fyi
cloud crater
Best to restart servers at all time, any restart solution can result in memory loss
keen compass
but that costs money last I recalled
kind crow
Live reload, yes. IDE is not important, I can switch

Other way you could probably do it, is launching the server with a debugger I think

hey guys, is there somewhere a good async mongodb tutorial? or the class, I kinda get the way how to use this but I don't find a proper class. Just saw that MongoClient for example is deprecated, so I'm kinda curious
undone narwhal
Have you already used async with minecraft?
MongoDB is not that hard, just search how to connect on google, the harder part is when you want to get data async and connect it with your player or the server

MongoDB not that hard - lol

yeah, I did. I also get the way, some years ago a friend hooked me up on how to use async with minecraft & provided me some classes/showed me how to work on it. MongoDB seems to be easy, but I saw that the MongoClient class is deprecated
that is my only concern, it is not on how to use it

Throw exception
sturdy oar
that could be an option
keen compass
you shouldn't throw exceptions if there is no reason to
bronze marten
you shouldn't throw exceptions if there is no reason to
@keen compass this haha, some ppl overthrow them
Returning null is prob the best
keen compass
no returning empty string is best
when you check it, just do String.isEmpty();
or String.isBlank();
sturdy oar
like this?
undone narwhal
Everybody uses null if it does not exists
bronze marten
But thats not intuitive behavior no?
undone narwhal
null means nothing
keen compass
it forces people to do a null check then
undone narwhal
So it makes sens to return null
keen compass
when you can simply just do isEmpty()
undone narwhal
Cause null check is almost everywhere
keen compass
only because people don't know how to use null properly
sturdy oar
ok! π
bronze marten
I mean its up to the context, if you always want something that wont behave unexpected go with ββ, if you want devs to think about their impl use null
sturdy oar
well I'll make sure to write documentation for that method
bronze marten
But in bukkit its kinda a standard to do nullβs
keen compass
null is certainly easier, but then you force more work on your users however when there are better methods. Nulls cause exceptions to be thrown sometimes if they are not checked
bronze marten
Yes give me a link as soon as its out
keen compass
so why do all that when it isn't necessary to begin with
bronze marten

@tropic nacelle wanna collaborate?

tropic nacelle
Make it so we can click a death message and it'll send a "Thoughts and Prayers" msg
keen compass
return "";
keen compass
not sure what you mean
undone narwhal
Don't you have to check if the returned item is null?
keen compass
no
undone narwhal
so you do a exists method right?
keen compass
I am not entirely sure what you are asking
if the method returns "";
its never null
undone narwhal
I mean, your telling me == null is bad cause it's object check
bronze marten
What
undone narwhal
But as the list returns null if the items doesn't exist, you first have to check if the return stuff is null
bronze marten
Its mem comparison
keen compass
I am saying returning null in methods is bad design if you have better alternatives
bronze marten
For null thats how you should check
keen compass
if you have no reason to force someone to check for null, then don't force them to check for null
undone narwhal
You're doing a double check...
keen compass
it causes a lot less problems
bronze marten
There also exists Optional
undone narwhal
Yes exactly
sturdy oar
no?
bronze marten
8?
keen compass
is it in Java 8?
bronze marten
Yeh
keen compass
interesting, well there is that
bronze marten
That way you can indeed do isPresent and you notify the developer intuitively that it might not be present
keen compass
anyways many people will recommend returning null, but it is bad design and causes problems in the long run when you simply could have just returned an empty value instead
keen compass
There is times where using null is appropriate. Like Player objects, because they can simply vanish, therefore it is appropriate to force the end user to check that the object is still valid.

ikr ffs

It won't be fun if they didn't change it

This is humor
inland oxide
looks like they unwrapped the TAG_List from the TAG_Compound for the NBT in the packet

Do you know any plugin that is good for Money? Like gMoney, gMoney just doesn't work on MySQL.
inland oxide
and on that note, going to sleep before someone starts asking me for plugin updates
undone narwhal
@soft tusk Something local ? Or Redis / other SQL / NoSQL ?
GUI is a visual interface. In minecraft we usually use GUI to speak about Chest inventories that are interactive (you can click on items as buttons)
neat orbit
Oh okay!!! So let's say a config for a votecrate is a gui?
soft tusk
I need god money plugin for residence (economy), which I can connect to MySQL
And more plugins
soft tusk
Can connect to MySQL?
neat orbit
Probably, just search MySQL compatible economy plugins
@soft tusk you should make sure to have Vault

Is there any packet that player sends whenever he eats/drinks or pulling bow?
As I see from test that I've done, player interact event has some delay due to communication with server.
I'd like to check for just client
undone narwhal
I think that the player sends the click packet when he starts eating. Then it's the server which tells when the eat is completed.
Cause if you're lagging, you can eat infinitely
chrome edge
Yeah, It's actually happen if you ever have ping.
So what should I do for checking those things with packets?
undone narwhal
I think it's the same packet sent as when the player right click
And for eat packet from the server I'll search that
Seems to be the PacketPlayOutEntityStatus with byte 9
chrome edge
So firstly, if you don't know, we can check if the bow pulling has cancelled with block dig packet
Okay, I'll try with PacketPlayOutEntityStatus
Seems work.
tiny dagger
undone narwhal
@chrome edge Awesome, thanks for testing it
@frigid ember ? What's the error, and can you give us more details?
chrome edge
@undone narwhal One more thing. You can check bow pulling has finished with block dig packet but cannot control is cancelled or not
frigid ember
Item: Diamond sword
slot: 9
lore:
-"A good sword"``` this is a config how can i get it to item stack and add it to invetory i tried for each but i dont get it to work
eternal jewel
hello guys can some one can sent the discord srv in here?
chrome edge
As I know the projectile shot event related to server due to entity spawn. It may be not possible for check bow is relased or not
frigid ember
can anyone help me?
undone narwhal
@frigid ember You have to get everything and build your ItemStack (get the Material from String, get the Lore, create ItemStack with the MAterial, set the lore, and give to the player on the slot)
undone narwhal
blackone1991 I'll go into that to check if this is possible, but Minecraft is sometimes tricky to use ^^
frigid ember
i tried for each it that gonnna work
chrome edge
Let me check some of the packets too.
eternal jewel
pls help i really need the bot
odd knoll
You can get it off Spigot.
odd knoll
You get them to put in all the necessary values them you get them and build an ItemStack from it.
frigid ember
for each?
odd knoll
For each item in the GUI, yes. If that's how you want to do it,.
frigid ember
}
``` will this work?You're looping through something that isn't a collection.
sturdy oar
which do you think is best guys?
@Override
List<String> findVersesContainingWord(String word) {
final List<String> foundVerses = new ArrayList<>();
for (final Chapter chapter : bibleImplementation.getChapters())
for (final String s : chapter.getVerses())
if (s.contains(word))
foundVerses.add(s);
return foundVerses;
}
// or
@Override
List<String> findVersesContainingWord(String word) {
return super.bibleImplementation
.getChapters()
.stream()
.map(Chapter::getVerses)
.flatMap(List::stream)
.filter(s -> s.contains(word))
.collect(Collectors.toList());
}
For instance, I loop through all the keys in the config and I have it like:
'1':
material: STONE
amount: 2```
etc..first
chrome edge
@undone narwhal I've found the way to check if player uses item. It has been added as a packet since 1.12.2.
frigid ember
first is more efficient
sturdy oar
probably
frigid ember
research about how slow streams are
chrome edge
but the problem is I'm trying to make anti-cheat lol. I've to check in 1.8 too
odd knoll
Streams can be slow AF.
sturdy oar
yeah bible is about 107'000 strings
undone narwhal
Fendi the first one is friendly to make a method, steam is useful when you make an operation is a method
Thanks a lot @chrome edge !!
sturdy oar
I'll try making a timing for both methods
frigid ember
k
sturdy oar
and see how much difference for bibles
frigid ember
if ur looping for verses in a whole bible
it can be slow af
in such cases, looping over a whole bible, performance is important
sturdy oar
Yeah that's why I've written both Stream and 'normal' java methods
i'll try how bad the streams make the performance drop
undone narwhal
Here is great
timid valley
for this it wont matter
i hope your not doing this piece of code 5000 times a tick. the heavy part will be the string searching
so streams vs normal won't matter
this might be a case where parallelStream() would help with expectation the string lists are large collections.
timid valley
i figured
that was my point, that the ovehread of streams is irrelevant here. it's not hot code
streams by default are slower, but if its not hot, it's not a big deal, and if you are ina situation you can benefit from parallel processing, they could help

Hello, i am trying to call a command through a datapack (mcfunction) created using a spigot plugin, but the server refuses the datapack because it does not recognize the custom command
eternal jewel
i really need the file
timid valley
what the spigot community incorrectly calls async, yes
sturdy oar
but then I'd need to remove the List and use something else
timid valley
for fastest results, dispatching an async task that runs parallel computation is likely the fastest result
nope
sturdy oar
well you're right
reading is safe
basically once the bible gets loaded it won't get modified
timid valley
.getChapters().stream(). to .getChapters().parallelStream()
frigid ember
it wont make sense to look for verses async
timid valley
yes it would, your printing result to end user
frigid ember
ud be waiting for an answer
sturdy oar
let me look real quic at the data
frigid ember
wait
dusty topaz
or your entire server would be waiting for the answer to compute on the main thread
frigid ember
make it async

timid valley
end user can tolerate a 5 second delay in response, main thread cant π

are you suggesting, aikar, that it is not okay to freeze main thread for 5 seconds?

isnt there some religious holiday called ash wednesday. i guess if its for religious stuff, that wednesday is ok too.

imagine religion didnt exist
no religious holidays

school :c
no holidays mid semester :c
timid valley
no school? do you only go to school due to religion?

??
timid valley
you said no school, why

we have these mid semester holidays because of religious holidays
otherwise we'd have school straight through whole semester(except weekends ofc)

you know youd prob be better off storing this in a sqlite db and then doing a TEXT search instead lol

i don't know
I mean yeah i could make a table for each bible, but i think they would be like hella long tables

row per verse, primary key compound on bookid, chapterid, verseid

Ty for suggesting it Aikar, I might switch to H2 or SQLite after having a stable version
timid valley
@frigid ember listen to your IDE. getconfigurationsection null check
frigid ember
aikar youd need a pretty large database

no

it's about 4-5 MB

lets calculate maybe
how much space it will take in memory
if we had all verses

why its null thats i dont know

i mean modern server have like 10GBs of memory

3MB is not much, but also note each char in java is 2 bytes

then add in jvm overhead i think is 8-16 bytes per object

use UTF-8

don't UTF-8 go up to 4bytes?

sturdy oar
the thing is that I won't only support english

I think UTF-8 covers any language anyway
frigid ember
nope
UTF-16 would
which is 2 bytes
UTF-8 uses 1-4 bytes
for example chinese(just example)
two byte
Every Chinese Character is represented by a two byte code.A
its return 0
sturdy oar
I might have to do some reasearch on characters
sturdy oar
It says UTF-8 uses 1-4 bytes
frigid ember
UTF-8 uses 1 byte for the first 128 characters, 2 bytes for the next 1,920, three bytes are used for the rest of the multilingual plane
ok
4 bytes are used for some CJK (Chinese, Japanese and Korean) characters
I may be wrong but I'm pretty sure that's how it goes
timid valley
simple ascii in utf8 uses 1 byte
frigid ember
yea
timid valley
but java represents a char as 16 bytes
timid valley
err
frigid ember
@timid valley why its return 0
timid valley
yeah meant 16 bits lol
timid valley
other encodings like SJIS use 16 bit chars
