Is there any way to convert v3 uuid to v4 in PHP?
noble lantern
on a i7
quaint mantle
4 hours
? what do you mean?
like port every methods + fields, etc, from spigot mappings to mojang mappings then make spigot there
quaint mantle
😬
noble lantern
prolly would take like 10-20 mins ide imagine if your pcs fast
or it could take 4 hours, never know
noble lantern
Is there any way to convert v3 uuid to v4 in PHP?
Nothing on google?
quaint mantle
wait how to port it then?

Is there any way to convert v3 uuid to v4 in PHP?
No, 3 and 4 are based upon different things
noble lantern
nope
Are you 100% that UUID you have doesnt need to be used through LiteBans API...
i seriously have a feeling LiteBans has an API your able to look at and see how they use that UUID to a Player object

Can't i just make litebans work with nicknames?
quaint mantle
i dont think so

what's the chance that two random uuids is equal?

vale ember
is it safe if i use random uuid's to identify buttons for event handlers?
eternal oxide
almost zero, but its possible
quaint mantle
hmm how to fix decompile issue, for example this?
private static final Comparator<Entry<String, FilledProfileResults.CounterCollector>> COUNTER_ENTRY_COMPARATOR = Entry.comparingByValue(Comparator.comparingLong((debug0) -> debug0.totalValue)).reversed();
10 633 823 966 279 326 983 230 456 482 242 756 608 different uuids can exist
the (debug0) in intellij marked it as an object
vale ember
so it's safe if i use uuids to check whether clicked item is correct button?
quaint mantle
so how to fix debug0 then
ivory sleet
so it's safe if i use uuids to check whether clicked item is correct button?
Define safe
quaint mantle
Yeah absolutely
eternal oxide
using random really depends on what will happen in your code if a collision does occur
I'd recommend creating a factory and store any generated UUIDs in a List as a WeakReference<UUID>
when you ask for a UUID, you generate one, see if its in your list, if not add it and return it
quaint mantle
Thats, like, pointless
ivory sleet
Thing is, WeakReference is like coupled to the instance you pass
eternal oxide
Don't ignore a possible game breaking action because its unlikely
noble lantern
Is there a way to force items to smelt in a furnace (those are sticks)
noble lantern
If a collision in your code could cause a data corruption
Theres actually multiple occurances of this been seen all around mc
In console especially there bug where people get switched with other mods due to clashing UUIDs
eternal oxide
Thing is, WeakReference is like coupled to the instance you pass
A WeakReference will allow the UUID to GC'd when there are no other hard references
ivory sleet
Yes but how does that help his case?
eternal oxide
as I said, you create a factory you request UUIDs from
ivory sleet
any uuid factory method has no guarantee of generating the same uuid instance, it’s basically a value based class
noble lantern
In console especially there bug where people get switched with other mods due to...
https://www.reddit.com/r/Minecraft/comments/r8zacp/the_game_tried_to_spawn_me_in_as_a_skeleton/
This is actually something recent thats been shown for older legacy versions on ps4
eternal oxide
That factory generates a UUID, checks its not being used, then adds/returns it
dusty totem
Hey, my server works on Linux in the background, as a deamon service,
my question is what signal I should send to the spigot server to have the same behavior as executing the stop command on the console?
ivory sleet
Yeah, although when Minecraft loads in necessary items, it may end up using a different uuid instance with the same content
eternal oxide
he's applying these UUIDs to buttons, so it would not be affected by MC in anyway
He's asking if hsi buttons could end up with collisions in their UUIDs
I'd guess adding to the PDC
ivory sleet
Yuh, it’s still a really vague implementation imho, seeing it as there might be a recreation of a uuid at any given implementation of the api, thus breaking the factory’s cache
eternal oxide
Yuh, it’s still a really vague implementation imho, seeing it as there might be ...
Thats impossible.
The factory is generating, checking and regenerating upon a collision
eternal oxide
Its similar to how Mojang would be generating their account UUIDS
ivory sleet
Yes but it’d lose the uuid instance if all hard references are lost making it enqueueable for gc as you said yourself.
eternal oxide
Yes but it’d lose the uuid instance if all hard references are lost making it en...
Yes, thats the point. When the UUID is no longer in use its GC'd and freed up to be used again
ivory sleet
Yes, but as he said, he’s using pdc
quaint mantle
Stop being paranoic, the factory is just overenginnering. How WeakRefference would help? Since he uses pdc, he probably wouldnt use the same uuid reference all the time,but convert it to the byte array and store/retrieve from container
eternal oxide
On a button, probably in a GUI
smoky oak
How high is the chance that a player has an already in use UUID?
smoky oak
no i mean if i use UUID as identificators for somethign lets say for some HashMap
eternal oxide
zero collisions
ivory sleet
Pdc requires a type aware token to store and load entries of given types. The implementation does not guarantee the stored instance to be the same when querying, which makes this implementation vague. Not saying it necessarily breaks directly but its definitely not reliable.
quaint mantle
Player UUIDs are account based and assigned by Mojang
cracked server sad noise
eternal oxide
*cracked server sad noise*
I did say if online
quaint mantle
oh that
eternal oxide
Pdc requires a type aware token to store and load entries of given types. The im...
Thats true
I'd not thought about the transitive nature of PDC
ivory sleet
Yuh, tho from what I’ve heard it’s basically a glorified LinkedHashMap or smtng
So should probably be fine 
eternal oxide
should
smoky oak
wait how quickly do PDC decay? I'm using them for data storage
eternal oxide
depends on what, and decay?
smoky oak
like if i go from 1.17 to 1.18 do they still contain their data?
eternal oxide
yes
ivory sleet
Yeah

nice works ty
maiden briar
Has anyone seen this before? reference to method is ambiguous
noble lantern
Are you editing a List or Map of some sorts?
maiden briar
System.out.println(reflectedObject.<Class<?>, Integer, Object[]>invokeMethod(String.class, 0, "aTest3"));
invokeMethod(Class<?> returnType, int index, Object... parameters)
invokeMethod(String name, Object... parameters)
These are the methods
smoky oak
probably. It's just a guess
noble lantern
I would assume its because you have Integer as an argument
Your cant use a java keyword as a argument without a value iirc unless your comparing types
maiden briar
System.out.println(reflectedObject.invokeMethod(String.class, 0, new Object[] {"aTest3"})); This works
But without the new Object[] {} doesn't
And the other 2 variations still work
ivory sleet
Object… vararg is shitty sometimes
Like since its an array interpretation the argument Object[] could be an array or just an element of the array
maiden briar
If I change it to Object[] parameter it works fine instead of Object...
ivory sleet
Thus the ambiguity
maiden briar

You need to null check killer because not all the time the entity gets killed by a player

my bad
i didnt reply to you
thats my fault
3 * 9 is 27
3 rows of 9 item slots
its 26 if your accessing it from an array yes
But the actual size starts at one
eg inv.getItem(27) will get IndexOutOfBoundException
but inv.getItem(26) is fine
inv.getItem(inv.getSize() - 1) returns same as the 26
sec
MoneyHash.java:178
show me that method thats near that line/class
The args your passing is empty
How are you sending your command in game?
and is args just from the onCommand method?
if args.length == 0
just remember its same thing as the inventory
if length is one, access it at 0

(Pls dont look through the rest, i have a big refactoring day tmrw LMAO theres alot of rather questionable things once you get to the crafting section)
ivory sleet
yuh
ConfigurationSection::getKeys yields a Set<String> and invoking Set::forEach on it takes a Consumer<? super String> (not UUID) so you'd have to parse the string and convert it to a UUID
probably an obsolete tutorial
ConfigurationSection section = ...;
section.getKeys(false).forEach(key -> {
UUID uuid;
try {
uuid = UUID.fromString(key);
} catch (IllegalArgumentException e) {
//handle if key is not a valid uuid
}
//TODO
});

if i have a yml value list like this:

Example: 1
Example2: 2
how can i set both example1 and example2 to 0 (using a loop on the test variable)
(i don't wanna write a line to set each Test.Value to 0, i wanna loop it bc i have more values)

is there anyway to add npcs without nms?
vale ember
either NPC specialized or nms wrapper
vale ember
not really
hoary pawn
but how can plugins do something with npcs then when it requires nms, doesnt the require a new server jar?
ivory sleet
wat
vale ember
wdym
ivory sleet
I mean, I know a lot of plugins which just hook into Citizens API
hoary pawn
doesnt it require a modifed server jar to edit nms
vale ember
you don't edit nms
ivory sleet
depends on wym with modify
vale ember
you just use it
visual tide
doesnt it require a modifed server jar to edit nms
to edit yes, but not to use
but why would you need to edit it
hoary pawn
i think i need to read a little up on nms lol
ivory sleet
but in principle not splyfof
there is intrumentation and some other stuff
which allows you to change classes at runtime
altho you need to declare an agent in that case
however you can still modify trivial things in nms like field values of instances
(which is basically reflection or unsafe)
hoary pawn
so if i wanted to add npcs i could do that with some stuff in a normal plugin
ivory sleet
basically yes
vale ember
yes
hoary pawn
ahh that is nice
vale ember
either with reflection or abstraction
hoary pawn
then its just impossible not totally impossible
ivory sleet
with that being said, I do suggest using citizens api to circumvent the need of direct nms
hoary pawn
with that being said, I do suggest using citizens api to circumvent the need of ...
well what do i learn from that xd
that would be too easy

Hmm if its for learning purposes then Ig
ivory sleet
but citizens api will require user to install citizens, yes?

how could i do that?
ivory sleet
you said you didnt want to use citizens?
vale ember
the problem is in hashmaps, if i use two identical itemstacks as keys, they override each other, which is normal behaviour, bet when i add SAME PDC to each of them, they suddenly duplicate in hashmap
hoary pawn
you said you didnt want to use citizens?
well i looked into nms stuff for 3 mins and gave up lol
vale ember
the code is: https://paste.md-5.net/ugajunewuf.cpp,
but the problematic part is "handlers" hashmap and methods at below which add/remove handlers, on every player join, i create new DeltaStack with identical paramteres, but on rejoin, the handler is called twice, and in hashmap, they are duplicated
but if i don't use pdc it works well

you mean itemstack

you can represent an item by mapping out all of its data
because the item object only lives in the jvm instance

as I say, modify CraftBukkit/nms class in runtime

why
thorny python
well, change some internal code for certain features, and reflection dont work to replace existing method

is that even possible?
reflection is basically the way of changing classes at runtime

as far as I know, is was possible in java8

reflection can change field value but cannot change method body

well it doesnt change classes
and you can actually through reflection set a private field

you could wrap the code within a method + class and send it to the compiler API, dynamically load that compiled class, and execute the method
so yeah it's quite complicated
