anemic causes big ball of mud in big enterprises.
slender elbow
i mean
you don't go neither nor the other exclusively in the entirety of whatever code base you're working on
you mix and match depending on the needs of the current problem you're trying to solve
trim quest
You have to write technology-agnostic code, when you want to write code that doesnt break easily. The infra code. Developers who use this idiom and write backend APIs even count the web frameworks they use as technology.
persistence api is also technology
anemic domains are dependent to persistence apis
ivory sleet
In practice its also not very useful to just boil it down to a duality such as rich vs anemic, there are almost always more important factors at play.

in web its pretty usefull
but for game dev, game modding

Serterano, DDD is certainly quite used in the industry, enterprise, but I do think if you preach about its cons and values, perhaps its worth teaching us, those that you want to inspire, about DDDs cons such as its prerequisite of a well understanding in regards to the business domain and the business requirements. Though that’s just my thoughts on it, take it-… inspirationally
slender elbow
they are guidelines

for me DDD is the max level that OOP dev can learn atm.

even DDD books tells this at preface (hands-on books(onion, hexagonal, clean archs), theoric books)
mortal hare
if you want to more maintainable system -> you go rich
im still against rich domain models, mainly because they work awfully bad without an session based ORM
if you're working in memory sure, but when it comes down to persistence from/to database it sucks
you still need to have anemic services for actions to orchestrate persistence between domain models and persistence apis, if you do rich domain entities from database, you end up with inefficient sql queries between the server and your application, unless you implement aggressive caching, batching etc which might clutter your codebase and make it harder to maintain than just maintaining a transaction script/service in one place and be done with it
my dogma is that less code = better, if its maintainable

When I use the code above, for some reason the direction-{x,y,z} values are 0, yaw works though
its called in PlayerInteractEvent
oh and the negativity of the direction vector is correct too, so its either 0 or -0
lilac dagger
you should do the following changes
Location eyeLocation = player.getEyeLocation();
Vector direction = eyeLocation.getDirection().multiply(0.2);
for (float i = 0; i < distance; i += 0.2F) {
eyeLocation.add(direction);
player.getWorld().spawnParticle(Particle.CRIT, eyeLocation, 0);
}
try this out

one small think
Vector direction = player.getLocation().getDirection(); this line should work
but the others i'm not sure
you're constantly changing the vector
when instead you should update the location each step by a little

thorn isle
the jit is surprisingly effective at getting rid of trivial allocations like these with escape analysis
but that of course requires the code to run pretty hot and get c2'd and is sensitive to unrolling/inlining limits
even then you'd be surprised by how many aabb/blockpos allocations the jit eliminates from the server tick loop
echo basalt
if you do a heapdump and look it up you don't see that many blockpos yeah
it's mostly long[] which I always assume is lighting data and NOT some sort of networking leak
thorn isle
long array sounds like it could be block data as well since the palette container for chunk sections is backed by one of those
echo basalt
could be yeah
I wonder if they do that smart shit where it only uses as many bits as it needs
or if they just store palette ids as longs because fuck you
thorn isle
it uses only the bits it needs, more or less
more or less as in the nibbles can't be split between two longs, so if 64 isn't divisible evenly by the bit count, there'll be some padding

i guess you're right
its a balance between coupling and cohesion
if you decoupled into one method interfaces you will essentially have low cohesion, low coupling system, which is harder to maintain
slender elbow
just use Haskell at that point
mortal hare
if you use meaningful interfaces you would make codebase which consists of high cohesion, medium-low coupling classes which is easier to maintain overall but a introduces some unnecessary coupling, which is ok since you can just refactor that interface whenever needs fit, its just not worth it to split it until you need it, since you usually expose interfaces and not the implementation classes to the client code

not even sure what Config.java does in this case
i think you can just delete it?
its used for forge mod configuration not for spigot
spigot bukkit api has its own configuration file api's
oblique furnace
looks like this now... I have compiled it but dont know where to find the compiled file😅
mortal hare
show me your pom.xml file
im not too familiar with Maven as i just use Gradle, but you should execute package maven task to produce jar file inside target directory
iirc you can enable package task in Maven by appending <packaging>jar</packaging> inside pom.xml file
oblique furnace
show me your `pom.xml` file
mortal hare
well im blind its already there lol
just click on package task inside maven sidebar list
and it should generate plugin .jar inside target directory
oblique furnace
It has made 2 .jar 😅
mortal hare
probably one is shaded and another not, but not too sure as i've last used maven like back in 2018
oblique furnace
one normal and one with "original-" infront
mortal hare
probably that's because shading maven plugin, which appends your project libraries to the .jar file, essentially makes a .jar file which contains all the classes your project needs
try using non prefixed one in spigot server
and see if that works
oblique furnace
ok
mortal hare
note that if you only want to produce .jar files you only need to invoke package task as it will invoke compile task automatically. Maven essentially has hierarchy of tasks, it usually chains them, you can also make your custom ones (99% use cases do not need that), its just a glorified interface for javac command line tool with an ability to download dependencies from the internet automatically 😄
oblique furnace
It worked🙂 Thanks alot for your help🤗
echo basalt
more or less as in the nibbles can't be split between two longs, so if 64 isn't ...
just carry it over across the next long?
thorn isle
this is how it used to work, but they changed it somewhat recently so they don't carry over
it did make the logic a bit simpler and maybe faster, since there's no longer a need for an edge case where you splice two longs together
i do wonder whether the new memory segments api would allow for a split nibble to be read from two longs by just fiddling with the offsets, but based on how addressing works in hardware i suspect that'd have to be done in software anyway and might not end up being any faster

IllegalArgumentException - if the access operation is incompatible with the alignment constraint in the provided layout
you can't use the method intended to get it as a long (or any of the provided varhandles to trick around that, it's all the same api), you could however do a copy into a single long-lengthed segment and get that as a single long
something like
try (var arena = Arena.ofConfined()) {
var longs = arena.allocateFrom(ValueLayout.JAVA_LONG, -1L, 0L);
var copy = arena.allocate(ValueLayout.JAVA_LONG);
copy.copyFrom(longs.asSlice(4L, 8L));
long l = copy.get(ValueLayout.JAVA_LONG, 0L);
assert (l == 0x00000000ffffffffL);
}
(or well it would be 0xffffffff00000000L if your platform is big endian, but lmao)
hm actually
the alignment is provided in the layout
scratch that
try (var arena = Arena.ofConfined()) {
var longs = arena.allocateFrom(ValueLayout.JAVA_LONG, -1L, 0L);
long l = copy.get(ValueLayout.JAVA_LONG.withByteAlignment(1L), 4L);
assert (l == 0x00000000ffffffffL);
}
it'd be interesting to try this out, but not really tenable since the longs are sent to the client as-is, and the client will explode if they don't have the padding it expects
we could convert them before we send them but that'd make sending chunks quite a bit more expensive than it is right now

not sure if it's worth the tradeoff

They are using a weighted color conversion algorithm which can produce different results
it emphasizes the yellows more
the one thing I did, which they didn't is the whole idea of centering and overlapping frames
Their entire system revolves around having a single block for a single frame, while mine uses transparency to allow for the overlap of frames and for them to be offset to be in any position
also their raycasting algo looks off

I need a custom worldborder so that Bedrock players can see it and I can also have a horizontal worldborder in general. My first thought would be to make it like the server MMCIsland with particles. But my minigame starts with a border radius of 1000 blocks, which would significantly affect performance, does anyone have any ideas or things I'm overlooking?
echo basalt
I remember working on this when I last did minigame work
In short it's really easy to make a fancy particle border that looks good
But you'd need some kind of algorithm to decide what parts of it should render
For example, you can say that you can render a border in a 48x48 radius around each player
I wrote this a while ago, might help
echo basalt

Guys 2 questions:
Is it okay to host my minecraft server using docker compose or k8s
And should i have one database for each plugin/gamemode (e.g. 5 mongodb instances) or should it all be in one database (e.g. 1 mongodb instance with 5 sub DBs)
sullen marlin
1 database should be fine to start

And yes you can host it with whatever you like
spare hazel
Ah nice

Mongo moment
Mongo is webscale 😉
spare hazel
Thank you mr spigot developer ❤️
So i should NOT use mongo and use something like postgresql?
spare hazel
So like mysql has the most compatibility?
sullen marlin
It's the most widely used
young knoll
Ideally relational data should use relational databases
However I do understand the convenience of just shoving everything into mongo
spare hazel

Plain old java objects
Basically a class that doesn’t extend or implement anything and has basic data types in it
Primitives, strings, lists, maps, etc
spare hazel
And then you can serialize&deserialize them?
young knoll
Yes
spare hazel
Thats cool
young knoll
It’s similar to gson
spare hazel
So heres what im gon do:
Mysql: 1 instance for basically everything: authme, luckperms, friends&party, lobby gadgets
Mongodb: one instance per custom game mode: skymines, roleplay, blahblahblah
It would be cool to store inventory data and player data in mongodb too and make the server state fully ephemeral but i wouldn't want to go through the hassle

The question wasn't about coding skills at all. It was simply a performance question.
To answer that: Yes you can make a big monolith
flint coyote
Leave that to the owner of the server. Maybe they don't need or want an anticheat, maybe they want a challenge, maybe it's more than one developer.
The question was if they can put THEIR OWN code all in one plugin instead of multiple, to which the answer is yes.
They can still throw thirdparty plugins in where they need them
Technically they can even copy a full open-source plugin into their own with some adaptations.
Although that would just make maintenance a lot harder

i remember fiddling with the color conversions back before paper built in that 16mb lookup table
iirc i used range encoding to compress it down to 2mb, lossless and from my benchmarking it wasn't any slower than the 16mb lookup table; memory locality helps with caching
i also vaguely remember trying some lossy compression methods
let me see if i can find my numbers
got it down to 500kb with ~3% of input colors mapping to the wrong of the two adjacent palette colors
looks like i also tried an approach that wasn't o(1), requiring in the worst case searching through 13 possible colors to match to, but that was lossless and 77kb
i originally used it for my own map image thing but since paper bundled in that 16mb cache i figured i might as well use it since it's sitting in my heap anyway
i also vectorized the color matching so those 13 color comparisons were done with one or two vector register ops
an absolute waste of time

young knoll
You could use a single scheduler and timestamps/instants
thorn isle
doesn't make a practical difference at such a low volume of tasks
the bukkit scheduler is kind of shit, especially for one-off tasks, but even then you'll need hundreds or thousands of one-off tasks per tick to make a dent in timings from scheduler overhead

then wait until users find out
fickle mantle
so if 15 players spam blocks

that'll be at most 15 tasks per tick

you mean it wont affect my performance?

the impact is negligible
and cooking up your own scheduler will probably just perform even worse than the bukkit scheduler

i'm willing to bet you're almost better of calculating and applying all damage yourself with your own damage modifier system
echo basalt
I do that
but it just calls event.setDamage
which fucks with item durability
with fucks with something else
I don't need this crooked system but I also don't want it fucking with my item durabilities
in this case I make the damage zero because some ability mitigates it
shouldn't make the armor unbreakable
mortal hare
im wondering if there's any implications splitting your fat interfaces into slim ones and then using type parameter to specify the narrowed type for the client class to depend on, like this:
@NullMarked
public class CachedPasswordRepository<T extends PasswordWriter & PasswordReader & PasswordChecker> implements PasswordWriter, PasswordReader, PasswordChecker {
private final T repository;
private final LoadingCache<UUID, Optional<String>> cache;
private CachedPasswordRepository(final T repository, final LoadingCache<UUID, Optional<String>> cache) {
this.repository = repository;
this.cache = cache;
}
// now you can access only read, write and check methods for password store
...
}
what do you guys think of this kind of go-ish approach where the class doesnt care what implementation or interface it is as long as it implements atomic interfaces it accepts it
you can future proof your code in a way you dont hardcode fat interfaces and only provide interface type which is really needed for implementation
kind also works with ISP principle of SOLID
its the best of both worlds, you can keep your API contract future proof by not tying it into bigger than needed interfaces and also encapsulate it for internal implementations if specific implementation relates operations between each other (for example caching reusing the same cache object, or database operations by relying on the same datasource reference/connection)
also you dont need to come up with weird names for such implementation specific interfaces
lilac dagger
i think this looks more complicated than it has to be
mortal hare
its like in go, where you declare what you need in the implementation side:
type Reader interface {
Read(p []byte) (n int, err error)
}
type Writer interface {
Write(p []byte) (n int, err error)
}
func process(rw interface {
Reader
Writer
}) {
// You can call both Read and Write on rw here
}
that way you declare what you only need in the code unit, sure this looks complicated, but then you have the ability to not tie in the implementation specifics into higher level class since you declare the contract in the client class not outside of the class
you can also design narrow mocks for specific use cases without implementing whole fat interface, you can also implement one fat interface mock and reuse it since it accepts any interface which has corresponding functional interfaces extended
icy imp
within constraints this is actually a pretty elegant approach.
mortal hare
this looks very flexible, imagine if new collections api would be made of atomic functional interfaces like Addable, Iterable, Deletable, Clearable, Readable, Writable etc, then you declare what you want on the class. for example you can make immutable collection which you can only read via static factory methods like this:
var collection = Collections.builder(Foo.class)
.add()
.contains()
.build();
and then use specific collection like this:
public <T extends Addable<Foo> & Containable<Foo>> add(T collection, Foo foo) {
if (!collection.contains(foo)) {
collection.add(foo);
}
collection.remove(foo) // compile time error since type parameter doesnt infer Deletable functional interface
}
the implementation of collection could be JRE vendor specific it can either downcast from AIO collection or implement specific one using some kind of chaining
i wonder if there's a lib like this yet
icy imp
hmm
slender elbow
that just looks annoying to use for client code ngl
icy imp
I see you getting forced back to using combining interfaces
mortal hare
why, it just that type infers of IDE's would probably struggle, but its future proofing your code dependencies to the narrowest types possible
icy imp
you cannot polymorphically store or pass around collections like this
mortal hare
you can supply more fatter collection interface and it will still accept
mortal hare
you cannot polymorphically store or pass around collections like this
why not?
mortal hare
I see you getting forced back to using combining interfaces
you can just provide default fatter impl factory methods ,like Collection.set() which would build fat one
icy imp
You're forced to propagate the generic type parameter everywhere tho
mortal hare
is that bad tho
slender elbow
if java allowed for type aliasing and declaring union types on 3rd party types, maybe, but otherwise, what shaikko said
slender elbow
is that bad tho
like i said, annoying to use in client code
icy imp
highly annoying
slender elbow
having to write the same thing over and over again
mortal hare
maybe java spec could introduce some syntax sugar to this but hell i like this
lets see if i could utilize this properly in my plugin
slender elbow
at that point i'd rather just use another language that allows for this more nicely
like scala
icy imp
^
slender elbow
this is not the kind of design that would be easily taken in java
and that's fine
it fits in other languages so i'd rather just use them in that case
icy imp
this got me thinking about witness pattern/phantom types
Slick does this I believe, think it would be enormously overkill for this.

Hey dumb question, but what event fires when a player clicks a bounding box
is it PlayerInteractEntityEvent

Yes

except for armour stands where it calls PlayerInteractAtEntityEvent

mortal vortex
Wonderful depiction
hard socket
there isn't exactly a central area
hard socket
Wonderful depiction
well it can be random
my goal is to get all the areas in the edhe
young knoll
Would that not be every area in the example
hard socket
is this example yes
hard socket
Every one is adjacent to at least one non-area
this is just an example
AAAAAAAAAA
AAAAB
AAAAAAAAA
AAAAAAA
hard socket
well if I can get B I can get every edge
young knoll
For each box, check if it is surrounded on each side by another box
If it isn’t, it’s on an edge
(Or corner)
icy imp
check north, south, east, west neighbors
if any direction has no neighbor:
A is an edge area```well thats the easy part
how do I check the neighbors
icy imp
I use R-tree spatial indexes in my plugin
thats probably highly overkill for what it sounds like you are trying to do. If you provide more context I can point you in the right direction
There are many ways to do what you are asking, not all are good for each use case
I would suggest maybe doing some research into how you could implement this for yourself, and if you have specific questions, ask them here. this is not really an area where we can just give you code solutions to the problem with minimal context.
hard socket
I just want to be directed to the right direction, I don’t need the code
Well thanks for the help
I will do some research
hybrid spoke
I just want to be directed to the right direction, I don’t need the code
so you are talking about pathfinding?
aha, 4 am realization. right direction to research, not anything ingame
we're dumb @icy imp, i spotted you
icy imp
I would look up boundry detection, spatial adjeceny queries, etc
pathfinding is not this
hybrid spoke
yeah figured, but tired it sounded like it lol

I'm pretty new to development but love trying out new things. I had a couple of questions about dialogues and their availability on Spigot.
Why are dialog only on Bungeecord? Will they be added to the Spigot API? How do I use them? These might be silly questions, but I'm still learning!

If I wanted to disable another plugin's EventHandlers for a specifc event for a specific condition, how would I go about doing that? I need to override McMMO's EntityDamageByEntity EventHandlers to not modify the damage in specific scenarios
I already tried unregistering the RegisteredListeners of the event, however that does it permanently and makes it so that their EventHandlers don't listen for any subsequent EntityDamageByEntity event, which isn't what I want
I thought about passing the event manually to their EventHandlers, but they're not static, so I can't do that
sullen marlin
There's not a built-in way to interfere with other plugins event listening.

Can't you keep it when you unregister it? Not sure what you mean by not static
daring light
Can't you keep it when you unregister it? Not sure what you mean by not static
Ah, I meant that the EventHandlers aren't static methods, so I can't just call them directly. I did find a possible solution though. McMMO offers constructors for their listeners, so I did it this way:
...
for(RegisteredListener listener : EntityDamageByEntityEvent.getHandlerList().getRegisteredListeners()){
if(listener.getPlugin().getName().equals("mcMMO")){
EntityDamageByEntityEvent.getHandlerList().unregister(listener);
}
}
mcMMO instance = (mcMMO) Bukkit.getPluginManager().getPlugin("mcMMO");
EntityListener listener = new EntityListener(instance);
mcmmo_entity_listener = listener;
}
public static void passEventMcMMO(EntityDamageByEntityEvent event){
mcmmo_entity_listener.onEntityDamageMonitor(event);
mcmmo_entity_listener.onEntityDamageByEntity(event);
}

Basically just overwrote an executor.
So u could take out mcmmos executor, and package it up in a nice package of ur own with some conditional check of whatever u want and simply only invoke the mcmmo one if the check passes/fails

SPI all the way, it is the clean and intended way of, well, finding and choosing a service provider
it might use reflection under the hood (it does, but that's not the point lol)

What's the right way to detect the java version a server is running?
slender elbow
Runtime.version()
alpine solar
Isn't that like java 9+?
slender elbow
:p you asked "what's the right way to detect the java version", and, well, that's the right way
in that case System.getProperty("java.version") probably, but idk the format of that in java 8
slender elbow
i mean if the Runtime class exists then it's definitely java 9+ so there isn't much to test if it doesn't exist, it's just java 8
err, the method Runtime.version(), not the class

and i'm running paper latest 1.21.4, but coding on the actual spigot api, not the paper one.
also feel free to ping me if you reply, otherwise i won't see your messages 😅
eternal night
running on paper is what could be the issue
empty comet
Since when? i've worked like that since the 1.8 days, so everyone can use my plugins even if they're on spigot or paper
eternal night
paper hardforked from spigot in version 1.21.4
eternal night
read their blog post on it
tl;dr for this support discord tho, replicate stuff on spigot not on paper even if you are using the spigot plugin API
empty comet
yeah well i can't work like that, it's already hard maintaining a multi-version plugin without breaking anything on ONE api, and now i need to actually compile and maintain my stuff agains't another api who's gonna change everything
ffs i hate changes

drop old versions ez
i would if mojang didn't drop a new version every weeks lol
echo basalt
and bukkit's color just shits itself instead of ignoring it
so I have to write this ugly code
wooden bay

Well, stick to either paper or spigot then.

echo basalt
bukkit my day1 op
eternal night
lol easy for you to say i guess?? i just found out i have double the work
it isn't easy to say, those are your options
you only do double the work if you want to support both
(not that the paper and spigot API have diverged a lot since the hardfork, the things diverging is new API added to spigot and paper respectively)
empty comet
yeah that's also why i don't understand my code not working, it should be the first version from the hardfork (and the itemflags didn't change since like 1.13 iirc)
i don't think paper changed much with their first version hardforked, but i could be wrong ofc
empty comet
you only do double the work if you want to support both
i HAVE to support both if i want to publish on spigot.com, THAT'S the problem
eternal night
for enchantment bookes specifically, HIDE_STORED_ENCHANTS is the thing you'd want to add
wooden bay
spigot.com? 💀

spigotmc.org sorry, always forgot they got this url
eternal night

Well no, to publish there you only need to support spigot
eternal night
uh
empty comet
and they didn't change the itemflags on .4, it's still the old system
eternal night
probably a thing in that version too?
https://jd.papermc.io/paper/1.21.4/org/bukkit/inventory/ItemFlag.html#HIDE_STORED_ENCHANTS at least paper had that flag in .4
idk how to get spigot javadocs for older versions
empty comet
ffs paper changed it on their first hardfork
empty comet
Well no, to publish there you only need to support spigot
yeah but everyone is on paper, that's the problem. spigot website is the most popular plugins website, but you can only publish IF you support the actual spigotapi, meanwhile everyone is on a paper server.
it's a difficult issue
anyway guess i'm dead for that issue, i can't rewrite an entire plugin for a new api and re-check thousand of lines for next week
slender elbow
you don't need to check thousands of lines
eternal night
I mean, at least for 1.21.4 the solution should be easy enough still
slender elbow
it's not like the paper api has changed in its entirety since hard fork
empty comet
yeah but i need to support both 1.8 and 1.21.4
eternal night
check if you are running paper, ItemFlag.valueOf("HIDE_STORED_ENCHANTMENTS"), otherwise HIDE_ADDITIONAL
slender elbow
yeah but i need to support both 1.8 and 1.21.4
okay?
that still doesn't mean you need to check thousands of lines lol
echo basalt
anyone versed in the cloud command framework? I'm trying to make an greedy list of strings that come from a specific collection

i mean i like to be thorough, i wanna be sure of everything.
anyway it's fine, it's just a small thing, but now i'm worried about other things
slender elbow
as time goes on, the APIs will be more and more divergent since they will differ on new API features
existing things won't really change for quite a while
eternal night

yeah they said that but look, itemflags changed on the first version of the hardfork.

i HAVE to support both if i want to publish on spigot.com, THAT'S the problem
i just split the paper specific functionality (under 50% of the plugin, but all the nice things) into classes that never get loaded on spigot
until i eventually forgot to add an if check somewhere that made the plugin explode on spigot, and after not checking the resource page for a few weeks I found it was deleted with seemingly no option for recovering it
it was something of a shame, but that particular plugin was at the end of its lifetime anyway, since fucking billy stole the entire feature into purpur, so i didn't bother making a fuss about it
