As a result of searching for a solution to generating a vanilla modefed chunk, I got the following answer - "Look at the net.minecraft.world package, all the necessary classes are there (or in sub-packages).
But this will probably not give you much, because
In vanilla there is no class ,,generation, - there are layers. (Several variants of smoothing, scaling, borders, bumps, noises, etc., in total more than 50 classes, if you do not count the classes of biomes, decorators and structures).
If you want to tweak the generation, it's better to use special events.
" - I came to the conclusion why I need it. And apparently I will have to use a resource-intensive approach and replace blocks via random in blockPopulator. But who knows if there are ways to "optimize the randomizer" to find the right biome with a higher chance?

is there a way to cancel a scheduled task? I'm changing blocks in the world and storing them into a hashmap, but if the entity uses that ability again to change the blocks it will get overwritten, so when the block change starts happening, i revert the old hash back to its old state, and then repopulate the hash with the newer blocks.
that's one way of the blocks reverting, the other is if the ability isn't used again in a set time, if it's not after a short delay the blocks will revert automaticlly. what happens, tho is that it also clears the map once it's done, so is there a way to cancel that task if the ability is called again?

Usually you would design the entire system in a different manner.
Its missing a lot of classes which are crucial for organizing your objects.
For example a PlayerOwnedMobManager which internally keeps track of every entity owned by a player.
Then you detect entities in the ChunkLoadEvent and ChunkUnloadEvent to make sure you dont miss
any rogue ones. Removing all entities owned by a player would be simply
UUID playerId = ...;
this.getOwnedEntities(playerId).forEach(armorstand -> armorstand.remove());
You can also be lazy and set the entity to not be persistent
Then it’ll get yeeted when the chunk unloads

I can only make an educated guess on how they achieve this.
But i am strongly leaning towards an architecture which can be deployed on CPUs with limited
single core performance but immense horizontal scalability. Such as having a separate
thread for each island, while still existing on the same server as others.
Where shared regions like the main island need to be deployed on high performance core CPUs because of
minecrafts core loop limitations.

sullen wharf
That's one way armor stands are usually used iirc
storm crystal
but I want to make it castable without need to have entity nearby and just damage all detected enemies in like 1x1 range of armor stand
sullen wharf
just make an invisible armor stand, get the entities around it and then damage those entities

yeah thats about it
I thought it would be harder but
there is literal method for that

Interact entities are perfect for this
the new ones?

it's just sad mojang didn't implement them earlier

Are interact entities basically what you mentioned earlier?
storm crystal
Interact entities are perfect for this
So it would be better than using armorstands?
sullen wharf
I mean, their main function is to be used as a trigger or just as a placeholder entity for stuff like what you need
I'm not sure but they should also be better in terms of performance

Most unhelpful is the WorldEdit API when tackling this problem as it provides 0 information on placement details. I do know the schematics width and height, but the placement in the world is relative to what position the schematic has been copied from

is there a non overly complicated how have recursive maps?
i have an arrays of strings {"a", "b", "c"}
I wanna create a map of maps like so
a{b{c{}}}
chat gpt wasnt helpful
hazy parrot
What
rotund ravine
chat gpt wasnt helpful
I gave it a go
Hello, this is Bing. I can help you with some Java code. 😊
A recursive map is a map that contains other maps as values, and can be nested to any depth. One way to create a recursive map from an array of strings is to use a loop and a helper method. Here is an example:
import java.util.Map;
import java.util.HashMap;
public class RecursiveMap {
// A helper method that creates a nested map from a string array
public static Map<String, Object> createNestedMap(String[] arr) {
Map<String, Object> map = new HashMap<>();
for (int i = arr.length - 1; i >= 0; i--) {
// Create a new map with the current element as the key and the previous map as the value
Map<String, Object> newMap = new HashMap<>();
newMap.put(arr[i], map);
// Update the map reference to the new map
map = newMap;
}
return map;
}
public static void main(String[] args) {
// An array of strings
String[] arr = {"a", "b", "c"};
// Create a recursive map from the array
Map<String, Object> recursiveMap = createNestedMap(arr);
// Print the recursive map
System.out.println(recursiveMap);
}
}
The output of this code is:
{a={b={c={}}}}
This is one possible way to create a recursive map from an array of strings in Java. There are other ways to do it, such as using recursion or streams. You can learn more about maps and other data structures in Java from this tutorial. I hope this helps. 😊

Somewhat correct ?
They also add a small one pixel dot and they color it gray so it is less visible. You can actually see it right next to the text if you look closely.
I believe I once stole a piece of code that does that.
But doing this with the vanilla font has the disadvantage of maybe being incorrect if ppl have resource pack that changes the font.
lost matrix
Somewhat correct ?
They also add a small one pixel dot and they color it gray so...
I usually just force a monospaced font in my server resourcepack and add spaces. Cleanest way for sure.
But for the vanilla font you need to do some trickery.
With a few lines of very basic code. Try to figure this one out.

I'm developing a "custom chests" plugin that, basically, allows players to have paged ender chests. Players must also be able to search items by query, and that's when I need a way to identify each item (I need to know their page and slot in the chest) to implement applied changes in the chest. The problem is that I cannot use NBT tags (nor ItemMeta, since item meta is just a wrapper for NMS tags) because I need items to keep stackable. After checking out NMS code, I found out that it's because two item stacks must have the exactly same NBTTagCompound in order to be stacked. My current solution is either patching the server (not preferred) or modifying the equals method using a bytecode editor, both to skip tags with a specific prefix from the comparison
I'm wondering if anyone faced this problem before or has any better idea
young knoll
Neither will work well
The client will still think they cannot be stacked, causing a lot of weird behaviour
waxen ledge
makes sense
eternal night
to implement applied changes in the chest confuses me ?
Player searches items and potentially removes them from the chest ?
waxen ledge
Sorry, I'm not a native english speaker. Yes, they may remove items from the search menu
eternal night
The search inventory is not the chest itself is it ? What prevents you from just keeping the page+slot number attached to the search inventory in regards to the displayed item
young knoll
You can have a seperate index that keeps track of what item is in what slot
eternal night
Like, you know what items you are showing in the search menu because you searched through your enderchest.
You hence also know where you found those items
listen to the removal of said items and yank them from the enderchest as well ?

Isn't this still slower in the long run?
Since reflections called upon many times are turned into bytecode
grim hound
Since reflections called upon many times are turned into bytecode
And I'm looking for how I could suggest the VM to do it right away
slender elbow
just have the Method/Field/Constructor in a static final field, the jvm will do what it deems necessary
"right away" is not a thing the vm does
the jvm's philosophy is that a piece of code will essentially run as few times so there is no real need to optimise things right away, then it'll keep statistics for every function invocation and when it does run more than a certain amount of times then it will optimise things
young knoll
The VM does not care for your mortal requests

Also, if we could specify, by "bytecode" they mean direct memory access?
Like player.handle.connection equivalent?
Those being variables

reflection is just fine for that, again just keep the reflection things static final and the jvm will inline the calls eventually into their actual instructions

Reflections.

alternatively you can use methodhandles/varhandles but yeah, more of the same things, maybe more raw but still needs to be inlined later by the vm

slender elbow
Yeah, but when they say it turns into bytecode, what exactly does that mean?
it means it'll turn into jvm bytecode
young knoll
Which is basically as low level as java goes
slender elbow
bytecode is bytecode, it's what makes up a class file, it's what the jvm reads directly and interprets and eventually hits c1
grim hound
So it accesses the memory place directly (field/method etc.)
slender elbow
like if you have a static final MethodHandle for some static method, once you call it enough times it'll be compiled into the respective invokestatic instruction
"yes"
grim hound
Like if it were a direct call
young knoll
yes
slender elbow
like if you have a `static final MethodHandle` for some static method, once you ...
technically it already is, but there is some indirection going on too. the jvm will later get rid of that indirection and inline it
grim hound
What does inline mean?
young knoll
And this is why spigot isn't super fussed over our reflective event system
rotund ravine
I recall the old event system
slender elbow
And this is why spigot isn't super fussed over our reflective event system
the problem with it is that the Method is not constant (static final) so the jvm won't really inline it
unless you turn on some experimental jvm flag
rough drift
I could update it to method handles
slender elbow
but that can break other stuff ofc
eternal night
I trust non static final things
rough drift
wouldn't be too hard

yo lyxnplay
im still suffering with the REST API thing
it requires a token and i cant figure out how to use it
young knoll
There are some other improvements that could be made
rotund ravine
Doesn’t the event system compile to asm
eternal night
that is paper
slender elbow
d*wnstream
rough drift
There are some other improvements that could be made
like?
slender elbow
p*per
rotund ravine
Oh i see
young knoll
Ability to use consumers for events would be cool
slender elbow
i mean
rough drift
oh fair
rough drift

slender elbow
do your own event executor
eternal night
p***r
young knoll
Well yeah, but simplifying it would be nice
eternal night
syntax sugar is always great yea
shadow night
can I run a mc server directly from IJ
eternal night
makes code taste better
rotund ravine
I usually write over the event system for good syntax sugar if i do something large
young knoll
I wonder if there would be any noticible performance gain from skipping events altogether if nothing is listening to them
Like, skip constructing the object + callEvent
rotund ravine
Probably not any major difference
eternal night
yo lyxnplay
im still suffering with the REST API thing
it requires a token and ...
you pass it ?
I presume
as a header with the name of token you pass the token
young knoll
Might help for some high frequency events
Idk I imagine the JVM is pretty optimized for object creation
blazing stream
I use [REST PAPI](https://www.spigotmc.org/resources/rest-placeholderapi.90266/...
fixed the issue by using https instead of http
now the new issue is:
{"error":"The required authorization heads were not present in the request."}
the plugin uses "tokens" for authorization... how do i send them in my https request? tried searching for them in the network tab to no avail
young knoll
Could just be a boolean check
eternal night
Like, every server gonna have a a dumb plugin listening to PlayerMoveEvent
eternal night
so now you won nothing just another thing to check
rough drift
Idk I imagine the JVM is pretty optimized for object creation
surprisingly
not so much
eternal night
Yea I guess ?
rough drift
I mean it's fast
eternal night
Valhalla
rough drift
but not that fast
eternal night
when
young knoll
I kinda want events for more things
rough drift
same
young knoll
But they might be too high frequency :c
eternal night
fixed the issue by using https instead of http
now the new issue is:
`{"error":"...
how are you constructing the request
eternal night
Gotta tell a player is moving somehow
just check against last pos per tick
young knoll
I wanted to allow injecting callbacks into anything that ticks
blazing stream
as a header with the name of `token` you pass the token
unfortunately that didnt work
young knoll
But apperently having server code directly call plugin code is against our API design
eternal night
unfortunately that didnt work
can you provide some code
Yea I mean
once that plugin unloads
its pretty not fun
now you have something referenced by the server that might capture god knows what
young knoll
I mean cleaning them up shouldn't be that hard
blazing stream
how are you constructing the request
const token = 'none' // 'none' is the actual token name
const response = await axios.get(`https://ip:8080/${playerName}/vault_eco_balance`, {
headers: {
'Authorization': `Bearer ${token}`,
},
});
'token': token
blazing stream
tried that too
eternal night
I mean cleaning them up shouldn't be that hard
ehhh
young knoll
Multimap<Plugin, Consumer<>> with weak keys mayhaps
eternal night
Well depends
yea but now your listeners need a plugin instance to register their callbacks
young knoll
Yeah that's the only annoying part
Plugin instance needed for many things
make me sad
eternal night
I mean, "callbacks into anything that ticks" also just like
blazing stream
error: 'The required authorization heads were not present in the request.'
young knoll
Slightly faster than keeping the stuff in a list and using a scheduler
Probably not by much tho
:p
blazing stream
const token = 'none' // 'none' is the actual token name
const response = await axios.get(`https://ip:8080/${playerName}/vault_eco_balance`, {
headers: {
'token': `${token}`,
},
});
The github source code does not produce that error o.O
it just gives you back "Unauthorized"
eternal night
Yea I guess 
probably just yanked back for any 401
young knoll
You just noticing the copilot thing now?
blazing stream
yea ig
eternal night
Yea lmao xD fucking copilot
rotund ravine
It’s true
blazing stream
what do i do now
rotund ravine
Somewhat
blazing stream
i dmed the dev
eternal night
yea or that
blazing stream
hes busy tho
eternal night
uuf
blazing stream
talked with him about a month ago on some random shit
blazing stream
and i dont know enough java to make my own rest api for papi

500 exposures
blazing stream
na
river oracle
500 exposures
I code for exposure its worth it. I mean exposure is really worth it. I've dev'd for thousands of startups for exposure and profit shares once the server makes it big
as you can imagine I'm still poor living in my moms basement
blazing stream
ill actually pay u 1 iranian riyal
young knoll
Are you telling me their million dollar server idea was not in fact a million dollar server idea
blazing stream
(defo didnt search what the weakest currency is)
river oracle
Are you telling me their million dollar server idea was not in fact a million do...
apparently not
blazing stream
I code for exposure its worth it. I mean exposure is really worth it. I've dev'd...
sounds like a....
skill issue
river oracle
I have worked on servers that didn't release though
but the thing was I was payed hourly
so like idgf
young knoll
I've done one commission so far
river oracle
then why u living in ur moms basement till now
I'm in highschool still technically
young knoll
The server made it like a month
blazing stream
same here
river oracle
I've done one commission so far
river oracle
The server made it like a month
ik then you get more comissions 😈
river oracle
I always find spigot pr's much more fun than comissions though
eternal night
I wanna say there was a spigot thingy
I had to run
to check their shitty checkstyle settings
wooden hearth
I would do it privately otherwise you will loose some money
eternal night
anyone with a quick hint before I go on a quest to finding it
river oracle
I wanna say there was a spigot thingy
you want to know how to check style
young knoll
lol
river oracle
could you possilby be talking about the development profile
young knoll
mvn whatever -P development
young knoll
to check their shitty checkstyle settings
👀
At least it's not BuildTools with C# style {}
