just to make it wait like 3 seconds before trying to load the data

wraith rapids
it would yes, but seems like a pretty fragile approach
ideally you would call the server saving the data and ask it to tell you when it's done saving
vast phoenix
what else could I do?
yeah
but
I don't want it to depend on the other server that is saving the data
wraith rapids
or use the transaction support of your database to make sure that the data is complete before you try reading it
it all depends on how you're networking between the servers
vast phoenix
I'll try some things out and I'll see what happens
wraith rapids
if all else fails, have a little value in your playerdata as stored in the db indicating whether the player is on any server currently
when the other server is done saving the data, it will set that bit to false
eternal oxide
Have you looked at the source for compareTo()?
vast phoenix
that would work too
wraith rapids
and the other server would not try loading it before the bit is set to false, and then immediately set it to true
atomically, ideally
vast phoenix
ok I'll figure it out
vernal basalt
idk how to word this but how do you make a "webpage" like dynmap although im doing a stat api
wraith rapids
String.compareTo doesn't actually compute the distance
it just checks whether each element is > or == or < and fast returns
iirc anyway

to speak with your server on webserver
if you store your data in a database which is not dynamic in runtime
just access the database

you can even use java i think

it wraps JDK's dedicated webserver
digital plinth
oh
wraith rapids
or more specifically, the plugin code asked snakeyaml to parse a config file
which asked the server to deserialize an itemstack
mortal hare
which is slow compared to webserver like litespeed

and that blew up
mortal hare
or nginx
wraith rapids
in particular it blew up while trying to deserialize the item meta of a spawn egg

You do not want to import com.sun.* packages

wraith rapids

okay thanks i fixed the issue by deleting a segment of a yml file that i did not tell the plugin to read
mortal hare
but its old
digital plinth
weirdddd
wraith rapids
the entire yaml file is read at once
quiet ice
the sun unsafe class still exists
wraith rapids
it doesn't go to the disk to grab the specific path you want when you call get
it loads the entire file into memory at once
and parses it all at once
mortal hare
the only thing i found there interesting is volatile arrays (not reference to the array)
quiet ice
what are those?
mortal hare
they kinda do exist
wraith rapids
they're arrays whose elements are volatile
quiet ice
java volatile or something else volatile?
wraith rapids
same principles apply to the array elements as would apply to a field declared as volatile
yeah, java volatile
mortal hare
volatile array would you be able to read items from primitive arrays without synchronisation from multiple threads, since it would flush LM cache everytime it access
wraith rapids
having to synchronize on an entire array or some shit just for memory visibility in a specific index is cancer
mortal hare
is there are manual way to flush LM cache apart from using synchronised codeblock
wraith rapids
i've even occasionally gone fuck it and just created a class with like 20 volatile fields or however big of an array I needed
mortal hare
i've even occasionally gone fuck it and just created a class with like 20 volati...
you only need one to update whole class fields while accessing that volatile field
wraith rapids
but of course that's fucking cancer too and only works for that exact array size and accessing it is even more cancer
well i mean synchronized code block doesn't flush anything either
that's a misconception from people dumbing down how memory barriers and shit work
wraith rapids
the actual underlying mechanism under the hood is fucking eldritch black magic and unknown and varies from mpl to impl
mortal hare
yesterday
wraith rapids
if the machine had to flush the related cache every time you refer to a volatile field or enter a synchronized block you would literally never get anything done
it's more fine tuned than that
young knoll
Maybe i'll just stick with an abstract method for each event, even though that is ugly
mortal hare
well this video
says that if one volatile field is accessed or written inside that thread
whole fields from thread are gonna be flushed after volatile field is written or read
i just can't find the right timestamp for it
mortal hare
ofc it its
wraith rapids
f.e an uncontended volatile is almost as fast as a regular field
while a contended volatile is much slower
wraith rapids
in a language as abstract as java you are kind of fucked when you step into the territory of "how do I make the machine flush this particular cache"
because there is basically never any guarantee that the machine does what you want
mortal hare
yea
wraith rapids
it might just not flush it in all silence because it deems it unnecessary
mortal hare
i would love to have an optional ability to destroy objects
like in c
since those are on heap
i mean it could run garbage collector, but it should give an ability to destroy them manually instead of waiting garbage collector
wraith rapids
touching anything related to the gc is kind of eeh as well since that is its whole own sector of black magic
mortal hare
I'm looking forward to the rust
some dude just showed me couple days
how awesome that compiled language is
and i should give it a try sometime in a future soon

yeah, we were discussing why MemorySection doesnt have a method for returning boxed integer instead of primitive one, but eh
ivory sleet
Just autobox?
languid geode
MemorySection in bukkit?

True
mortal hare
Objects can be null, but not primitives and that's the point of this discussion. Bukkit configuration api when getting value from memory return primitive int instead of boxed integer, that way it needs to fallback to its default values of primitive, instead it could be checked as null
vital ridge
Well as much as i understood from the jdocs

I mean isSet exists

my map is immutable
aka i cannot modify it
aka im fucked

oh well the reason for that is mojang the more complex explanation is in hub.spigotmc.org/stash
mortal hare
maps are not immutable, unless you use some kind of implementation of it
languid geode
my map is immutable
What unless you defined some kind of write lock implementation thats just not true
vital ridge
Map<Enchantment, Integer> enchantments = item.getEnchantments();
It does say on the javadocs it returns an immutable map of the enchants
vital ridge
this is my map
young knoll
Correct, this is what add and removeEnchant are for
mortal hare
there's specific methods for adding enchantments
languid geode
What event are you using
Get map of enchantment (levels, keyed by type) to be added to item (modify map returned to change values).
are you using prepare?
vital ridge
Iam now since EnchantItemEvent basically didnt even run my code
Im trying to multiply item enchantment levels everytime they are enchanted
so if you enchant and get sharp 2
languid geode
Is this a bug? its supposed to work easily
languid geode
@mortal hare where did you find that code
mortal hare
its immutable since it uses custom extended class which is extended treemap
mortal hare
<@!277517157053628418> where did you find that code
intellij magic
languid geode
I get that but what class
languid geode
Why you trying to edit the enchantments on a itemstack use the event method
wraith rapids
most developers have sources
languid geode
@wraith rapids I got the full source i dev for the main branch
vital ridge
Well last time i wanted to try this but i ditched it:
e.getItem().addUnsafeEnchantment((Enchantment) e.getItem().getEnchantments(), randomMultiplier * e.getItem().getEnchantmentLevel((Enchantment) e.getItem().getEnchantments()));
What i do is use some kind of method to get and object which i want to peek at,
then i do CTRL + left click to peek inside and then if its interface i right click, press go to, and click go to implementations
languid geode
Yeah but your doing it wrong you need to modify the map that the event gives you
mortal hare
its very useful and saves time
languid geode
Im well aware i used intellji the past 4 years now xD
wraith rapids
you can also use middle mouse button instead of ctrl-lmb
languid geode
Dont ask questions when it comes to NMS please
mortal hare
😄
languid geode
We hate touching that dump tbh but we cant avoid it
wraith rapids
i guess the tree map is slightly smaller for most items
memory footprint wise, anyway
but like, I doubt that's the driving force behind that decision
vital ridge
so anybody has any ideas
wraith rapids
mojang and performance or efficiency don't go hand in hand

idk why I am so lost to this: I want to make a variable int hashitmanytimes in EntityDamageByentity event and every timeplayer hits a entity the value goes up by 1 like hashitmanytimes = hashitmanytimes++; but hashitmanytimes needs to have a value of 0, but I just dont know where to put it so if I hit an entity the value will not be set to 0.
young knoll
What
wraith rapids
what
fresh heath
so basically when player hits entity then hashitmanyitems goes up by 1
wraith rapids
hash it many times
undone pebble
HasItManyItems
wraith rapids
has hit many times
fresh heath
yes variable called has hit many times
ivory sleet
Hash it many times lol

fresh heath
is hash just pretty much checking if 1 value is equal to another
wraith rapids
hash my browns
undone pebble
no potato
fresh heath
stupid potato
wraith rapids
anyway
describe what it is that you want to achieve
and what I mean by achieve is not "i want a variable that does this", I mean what do you need that variable for
mortal hare
hashing is like roughly putting a data through hydraulic compressor. you can decompress it, if its backward decodable.
wraith rapids
your question is nonsensical and nobody has any idea how to answer you
languid geode
Has anyone of you had to look thru the spigot source NMS classes
mortal hare
yes
mortal hare
im doing it rn
languid geode
Im crying RN have to access some very old nms
wraith rapids
i've had to fuck with nms plenty as well
languid geode
this shit looks like it was writen by a monkey on a typewriter
wraith rapids
one of the more irritating cases is the lobotomizer timings integration
aikar just had to go and fuck it up
ivory sleet
It may look worse cuz its decompiled but yeah some nms back then wasnt just good
wraith rapids
fuck aikar, I will shit on his grave
languid geode
@ivory sleet Got original access to the mojang github
ivory sleet
ah
wraith rapids
in paper 1.16.4 or .3, aikar changed the way how entities hold onto their timigns handlers
it used to be that every entity had their own handler reference
fresh heath
basically if player hits entity 10 times then they will get strength, all is done expect the checking if player has hit 10 times
wraith rapids
that just referred to the common handler instance of that entity type
languid geode
Still hurts even if its not method a b c d x
mortal hare
and why does it bother you?
wraith rapids
that is to say, I could change the handler of any specific entity, and then that entity would count towards a different timings section
however, he changed it
now, the reference is on the entity type
ivory sleet
bruh
wraith rapids
which means that to change the timings entry an entity counts towards
I need to create a new fake entity type for it
assign it to that type
then reflectively hack into the final entity type of that entity
and hammer the new fake type in it
mortal hare
is that a struggle for you because you register custom mobs via nms?
wraith rapids
it's a struggle because I want lobotomized villagers to show up separately on timings
which means that some villagers need to use a different timings handler than others
mortal hare
^^ perfectionist
why does it bother you to have that timings tab
ok its better to debug
but its not like important or anything
wraith rapids
it's really useful because it lets you know how much of an effect the plugin has on the server performance
it lets you keep track of whether your players are keeping villagers in a lobotomizing compatible way
mortal hare
well he probably changed it to have better performance
vital ridge
-------------- >>>>> EnchantItemEvent:getEnchantsToAdd <<<<<--------------
I think you shouldve told me to just to e.getEnchantsToAdd since i dont know those keywords
wraith rapids
doesn't affect performance really
vital ridge
I now understood what i need to do
mortal hare
or have less memory footprint
wraith rapids
it's just an extra field access per entity per tick and an extra 32 bits of memory per entity
literally insignificant
mortal hare
eulers constant
vital ridge
Yea okay gotchu, i just dont know those keywords lmao
ivory sleet
keyword?
vital ridge
Thanks anyways
wraith rapids
:: and # refer to instance methods usually
languid geode
Keywords?
wraith rapids
. usually refers to static methods
languid geode
did he just call an instance a keyword
ivory sleet
javadocs inconvenience uses # for both static and instance methods 🥲
languid geode
javadocs inconvenience uses # for both static and instance methods 🥲
Just pay attention to the access types
I swear to god im gonna have a mod pin Read the documentation before asking a question or something along those lines
!jdocs
darn
wraith rapids
the # in javadocs is just a html anchor for the specific line on the page
mortal hare
Static method (initialised only once and only when called first time) - ClassName.staticMethod();
Instance method (initialised once per instance) - Object.instanceMethod()
Same rules are valid for fields too
i might be wrong about static intialisation time, but that's valid for fields idk
fresh heath
how tf I have read so many articles of Hash and all I have gotten is "key"
languid geode
Yeah there is no instantiation in statics i believe
wraith rapids
hash has nothing to do with what you're trying to do
mortal hare
Hash is a blob of encoded data which can be used to secure data or be compressed and then decompressed with special programs, and its used in blockchain like cryptocurrencies
What are you mentioning is the HashMap. Its a map with key value structure, which uses Hashes to access the data fast by using key as an object
wraith rapids
no i just said that your variable looks like hash it many times
hash it many times
has hit many times
anyway, what you want is not a variable
you want a map that keys Player -> number of times hit
which incidentally is going to be a Hash Map
but you can just forget about the hash part, that is coincidence
and now he is even more confused
fresh heath
I kinda dont want u to giveme answer but just what do I need to do
wraith rapids
do you know what a map is
fresh heath
hashmap ?
wraith rapids
no, a map
mortal hare
Map is literally a map
wraith rapids
a map is a thing that associates things with other things
mortal hare
but stored inside computer
wraith rapids
for example, a map could associate a player's name with the number of times that player has punched
wraith rapids
then you could give that map a player's name
and it would return you the number of times they've punched
fresh heath
so basically map just stores values
mortal hare
Yes
fresh heath
so what is the diffrence between int ....; and map
mortal hare
lemme gimme an example
fresh heath
map is a String ?
fresh heath
actually 10,000 or like u meant infinity
wraith rapids
indefinitely many yes
have you ever used a phone book?
you know, a book with peoples' names and phone numbers in it?
mortal hare
Player player = e.getPlayer();
Map<Player, Integer> playerData = new HashMap<Player, Integer>();
kills.put(player, 5) // Sets data for that player to 5
Integer kills = kills.get(player); // Gets the data of the player
yes
mortal hare
if it has names of people, yes
wraith rapids
its values are the persons' phone numbers
fresh heath
```java
Player player = e.getPlayer();
Map<Player, Integer> playerData = new Ha...
I read exactly that
wraith rapids
if you want to know someone's phone number, you open up the book
you find the name of the person
and then you look at the phone number written next to it
doing this is the same as calling map.get(person's name)
map.get(person's name) will return person's phone number
digital plinth
hmm is it possible for a plugin to make mobs fight other mobs
mortal hare
Map<String, Integer> numbers = new HashMap<>();
numbers.put("John", 440547865);
Integer number = numbers.get("John"); // Gets number of john from phone book map
put
fresh heath
yes I got that
wraith rapids
kek
well, now, you want to track how many times each player has punched
you create a map
with the players as keys
and the # of times punched as values
and then just call .get and .put accordingly
fresh heath
so I make map put like Playerkills, 10
and then I get Playerkills and it is 10

Hello 🙂 Have a question... I am now working on custom virtual inventory, that player access with command and I want to allow player to take items from that inventory out to their, but not from their inventory to the virtual one. Can someone help me with this out?
fresh heath
I am here no idea what next
Map<String, Integer> PlayerKills = new HashMap<>();
PlayerKills.put("hashitmanytimes", 0);
you want to use the player's name as the key
fresh heath
I am glad I am even here lol
wraith rapids
that way every player will have a record in the phone book
when your plugin starts, your phone book will be empty
because nobody has punched yet
mortal hare
Hello 🙂 Have a question... I am now working on custom virtual inventory, that p...
click event, drag event
fresh heath
PlayerKills.put("My name", 0);
wraith rapids
you don't have any phone numbers to record
but when someone punches
you want to listen to that event
open up the phone book
and then increment the value in the phone book
if they aren't on the phone book yet, you add their name and write 1 next to it
viscid oasis
click event, drag event
well yes, tried some things, but it only register the initial click, not the placing one...
wraith rapids
if they are, you replace the number next to their name with a bigger number
mortal hare
check if clicked slot id is lower then top containers lowest id
wraith rapids
if (map.contains(player.getName()))
check whether the player is on the phone book
if they are, get their current number
mortal hare
or the opposite
wraith rapids
int number = map.get(player.getName())
and then increase it by 1, as they just punched
number = number + 1
wraith rapids
then write it back in the phone book
fresh heath
so this
Map<String, Integer> PlayerKills = new HashMap<>();
PlayerKills.put("MrCooxie", 0);
Should not be in EntityDamageByEntityEvent
mortal hare
and store it somewhere
wraith rapids
map.put(player.getName(), number)
wraith rapids
no, what you are doing there is hard-coding the name
you want to get the player's name
mortal hare
if clicked slot is higher than bottom inventory's highest slot, then cancel event
otherwise dont
if you want to place items inside
but not outside
viscid oasis
or the opposite
well i create the inventory from mysql data, player votes, with votifier i store the number of votes in db, then when creating inventory i take the number from db and make it as same number of specific item. and i need to allow user to only take this items out, like as atm, not allowing to put anything back... when they take items out, it triggers event that count items that is left in inventory and save that number back to mysql...
fresh heath
Sai Nnya...
you don't have any phone numbers to record
but when someone punches
you want to listen to that event
open up the phone book
and then increment the value in the phone book
if they aren't on the phone book yet, you add their name and write 1 next to it
How the hell should I know how to do that.
wraith rapids
didn't you have a code snippet earlier where you were listening to like player interact event or something
mortal hare
well i create the inventory from mysql data, player votes, with votifier i store...
literally do what i said
but opposite
if clicked slot is lower than top inventory's highest slot - cancel event
fresh heath
How you guys get so good at java like bruh
wraith rapids
we started with a guide on how to deal with java
mortal hare
wait till you see C
wraith rapids
and then we did java until we got comfortable with it
then, and only then, did we move to the bukkit api
mortal hare
C is more archaic than java
viscid oasis
``if clicked slot is lower than top inventory's highest slot - cancel event``
but it disable moving items around player inventory as well?
eternal night
also really hating yourself helps if you want to sink days or months of work into java

Hello! I finished setting up a spigot local server earlier and i'm trying to make my first plugin ! I'm following the gradle tutorial on the wiki, and i'm wondering, which sdk is better? Are they all just as good or is there an advantage to going with version 11?
I have 0 experience with Java or making plugins/servers
mortal hare

it disables whole bottom inventory clicking
what you can do actually
is to check
fresh heath

isa snippet another java thing
mortal hare
if clicked slot is inside the top inventory range
wraith rapids
snippet just means like
excerpt
part of something
not programming or java related
it's just an english word
viscid oasis
if clicked slot is inside the top inventory range
and in this example if i check if click is on top inventory, it will prevent user from taking the items to their inventory
fresh heath
I have
@EventHandler
public void onhit(EntityDamageByEntityEvent event){

If anyone could help me it would be great :)

wraith rapids
if you have 0 experience with anything, go read some guide
mortal hare
if (e.getSlot() <= e.getInventory().getType().getSize()) {
e.setCancelled(true);
}
try this
wraith rapids
then come back with at least a little bit of experience
mortal hare
this would not let click inside top container inventory
wraith rapids
learn java first; look up some guide and then try doing some simple excercises with it

}
wraith rapids
real men go with 8
mortal hare
what about this?
if (event.getClickedInventory() == inv && event.getCursor() != ...
that should work too actually
wraith rapids
you'll want to prevent shift clicking from the other inventory
if you're preventing people from placing stuff
and if you're preventing people from picking stuff, you'll want to prevent COLLECT_TO_CURSOR in the other inventory
nova lark
@eternal oxide Thanks alot !
Now i'll come back when I have a master's degree

if you already know the basics of java, then that's fine

omg why it cant have initiation click event and destination click event... 😄
mortal hare
because mojang is too dumb
to include it in their packets
when you shift click
it doesnt tell you where the destination
is
in sent packets
kinda dumb since client calculates destination and then server recalculated that destination
wraith rapids
that's no excuse for bukkit not to include it though
mortal hare
doing twice the job
wraith rapids
the server computes it anyway
viscid oasis
InventoryMoveItemEvent like this will be the best one, but it does not work for player interaction...
wraith rapids
might as well expose it in the api
now it needs to be done once by the client, once by the server
mortal hare
Bukkit is not implementing this
wraith rapids
and once by every fucking plugin individually
wanton cipher
how a plugin to make ranks apear on ur head ?/:
mortal hare
it would break backwards compatiblity
wraith rapids
oh yeah those poor fucking 1.8 plugins
mortal hare
its an internal NMS implementation
wraith rapids
still should be exposed in the bukkit event
mortal hare
which i cant find lol
i overriden that
to calculate proper shift clicking
only in bottom containers as i provided
wraith rapids
is that the thing you've been fucking with for the past few days
mortal hare
you mean the mojang server impl computes the shift click results wrong?
it doesnt
but it computes it wrong according to the rules of GUI
viscid oasis
looks like i leave the idea of inventory, and just give them the items with commands...
wraith rapids
is there a difference
mortal hare
do you want to have shift clicked items in to the GUI elements itself?
wraith rapids
what's a gui element
wraith rapids
what
mortal hare
Inventory GUI's ffs
wraith rapids
you have completely lost me
mortal hare
Have you heard of concept - Inventory GUI's
wraith rapids
yes
mortal hare
try to shift click
while open
it will end up in the inventory gui itself
that's why i overriden it
wraith rapids
ah so you mean you want to reimplement shift clicking so that you can blacklist certain slots from being shift clicked to in such guis
mortal hare
kinda
wraith rapids
i looked into that at one point as well
and then decided it wasn't worth the effort
mortal hare
i already did it
it works pretty well
but its not blacklisting
it disallowing it for all the types
mortal hare
idk
quaint mantle
I mean*
wraith rapids
some guis could have slots that you can use as if it was a container
is your thing flexible enough to let me shift click shit into those
mortal hare
yes
wraith rapids
so it goes on a slot by slot basis
vital ridge
do yall remember my enchantment issue?
young knoll
Did you just correct me
vital ridge
Basically , nothing wrong under the event
mortal hare
goddamit
vital ridge
But i was wondering
young knoll
On a message from February
mortal hare
that bot
vital ridge
how could i do it under a normal runnable (runtasktimer)
wraith rapids
why is it necessary for this to happen on like the packet layer though
mortal hare
why is it necessary for this to happen on like the packet layer though
because my implementation is packet based
since inventories in bukkit are synced
and having GUI synced for no reason is kinda useless
wraith rapids
is it not possible via events
mortal hare
the thing is my GUI api prevents dupes
since my items are packet based
even if they would get the item out of the container
wraith rapids
ok why are your items packet based
mortal hare
because they're decorations
wraith rapids
is your entire server on the packet layer
mortal hare
which shouldnt be picked up
wraith rapids
you could do that with events just as well though, right
young knoll
I cant say I've had any duping issues using standard events
young knoll
Except when I realized open inventories for sleeping players is jank
mortal hare
it could lead to bad consequences
mortal hare
also you don't need to send bunch of packets
to the client
while with inventories you need to since they're just inventories
wraith rapids
meanwhile fucking ImageOnMap dev team refuses to patch a gui dupe issue that spawns in barrier blocks
because "it's a minor bug and kind of rare"
fucking
mortal hare
that's why i was inspired to do this kind of shit lol
wraith rapids
had to fork that piece of shit and change the barrier icon in the gui to like red glass pane
mortal hare
to prevent this shitty dupes
eternal oxide
because "it's a minor bug and kind of rare"
That usually translates to "we've no clue how to fix it"
wraith rapids
it's happening in the depths of some shit tier library they're using
i wouldn't be bothered to fix it either

generics are funky
i made me a train
it's kind of like a linked list but every element can be of a different type
and it's type safe 👀
sage swift
isn't that like a node
wraith rapids
dunno, wouldn't node imply that there's more than 1 neighbor
this is a singly linked list so every element only points at the next element
i don't think it's possible to make it type safe if it's doubly linked
well, actually, I guess it might be possible
lemme give a try

Hi, is there a way to remove the death particles of mobs ?
The little "poof"
It should be "Particles#EXPLOSION_NORMAL"
But cancelling this packet doesn't seems to work :/
mortal hare
have you tried debugging it
if it fires
?
what you can do instead then, if client is fucking around - just set mobs health to 1 heart before its dying
then play death animation
and after 0.5 sec send entity destroy packet
then kill the entity in the server
idk if it would fire up the entity packets
probs it would
or remove it somehow from world
