proabably every line of code u wrote was already written at least once before
no, I once wrote a java class that used so many generics, I believe if the founders of java generics saw my code they'd revert the changes

probably been written before
maybe not same usecase
how many generics can one use in a class im curious now
what could u possibly have in a class that would need it to have more than like 5
icy beacon
probably been written before
there were like 9 generics and some of the types after initialization also used generics
I don't even remember why because that code is long gone thankfully
tender shard
how many generics can one use in a class im curious now
at most 2.1 billion

You can create custom persistent data types on your own, or use one of the many libraries available which have implemented those which match your needs. Learn about more persistent data types here: https://www.spigotmc.org/threads/more-persistent-data-types-collections-maps-and-arrays-for-pdc.520677/

Anyone been able to make a good decoy entity?
Like an invisible, uninteractable Cat/Ocelot to scare creepers away or a Wolf to scare Skeletons.
I need it to be attached (or follow) to the player in some way.
I have code that gets very close, but the entity will still be in the way and block hits and block interactions.
Is there a way for me to like, spawn an Item entity, attach it as a passenger, then trick the server into thinking it's a cat with packets or something?
young knoll
Does a cat actually block interaction when itās on your head?
mental moon
Yes.
When attached as a passenger, it gets in the way from you doing anything.
Can't interact or mine or punch
young knoll
You can offset it by stacking it on something else and then stacking that on the player
mental moon
I could make a tower of Item entities all with nested passangers, but if the player needs to mine a block above their head it still will be in the way
young knoll
Or you can just constantly tp it to the players location + x
young knoll
Or you could get messy with NMS and mess with creeper ai so they fear players
mental moon
I'm very happy having somehow not needed nms in my plugin yet.
I'll see what I can do with the bukkit api, then if the nms way is straightforward I'll dive in š„²

How I detect uhm slim mc skins
check the texture out for blank texture
skins are downloadable
near kite
check the texture out for blank texture
what does that mean
wet breach
well skins are pictures
you only need to check within a certain size the squares missing color
near kite
so a blank texture where the arm area is
or i check if there is the black hex
mc gives
no wait that would cause problems
wet breach
you won't use the api here except for obtaining the link to the skin to download
once you have the skin picture, you will use the specs required for skins
then its checking the appropriate areas for missing color
or it has transparency
since it will be a png
wet breach
from the byte information of the png
png has a spec itself
that tells you how each pixel is stored and its information
near kite
so what spec would i need to check
wet breach
png and mc skins
young knoll
You can also just use the PlayerProfile api
hybrid spoke
where do i check the transparrecy tho
you cant just check if its transparent
hybrid spoke
you cant just check if its transparent
you gotta go through the pixels
near kite
and geysermcs skins arent in their api
young knoll
wet breach
You can also just use the PlayerProfile api
player profile api will only let them get the link to download the skin
oh guess it has the slim thing
not sure if that solves their problem or not
but I suppose that works
near kite
cant use a spigtmc apii ether since what im doing is the backend of the plugin
hybrid spoke
you probably have to download the skin as an image and go through that pixels then
near kite
so how would going through the pixels work then

not download since i already have that part covred
wet breach
so how would going through the pixels work then
what do you mean?
it sounds like you are asking in a way you want us to do the work for you
near kite
no
i was just asking if i need to search the main area of the skin
i have a idea how
wet breach
I already told you png has a file specification in regards to how information with pixels are stored
you need to use MC skin specification so you know the size and areas you need to constrain your search
near kite
i think i did it

that aint a dev thats someone using chatgpt

echo basalt
Why the fuck is luckperms' bukkit plugin just a jar in a jar and a fancy classloader
bro?
slender elbow
because it needs to add the dependencies to the classpath
it just bootstraps everything
echo basalt
Elaborate
slender elbow
the plugin classloader does not allow you to add elements to the classpath (the downloaded dependencies)
so it uses its own classloader to do it
echo basalt
Yeah but the dependency manager system also has a separate classloader to load dependencies
Maybe I should learn about classloaders
I really want to do something similar but this is breaking my brain
slender elbow
Yeah but the dependency manager system also has a separate classloader to load d...
those are a bit special, it's for isolated dependencies that don't use the plugin/server classloader as parent
you'll see a ClasspathAppender or something, that's an interface implemented by the bootstrap classloader to add jars to the classpath, and that's where the bulk of the dependencies end up in

what does java reflection mean and does it have something to do with creating instances of classes? (should I avoid it? I heard that reflection is bad for perfomance)
echo basalt
Java's reflections system is a native api for playing with classes and their fields and methods natively
Let's say you have something like
public class MyClass {
private int number = 5;
public int getNumber() {
return number;
}
}
You can access the number field and make it accessible
MyClass instance = ...;
Field field = MyClass.class.getDeclaredField("number");
field.setAccessible(true);
field.set(instance, 10);
You can also get constructors and invoke them in code
It's mostly used when dealing with hacky stuff
Like accessing private fields or injecting data
Or annotations
carmine mica

depends. It can be just as fast as normal code if you use the correct APIs and set it up correctly

Yeah so fields can be cached
Getting a field can be expensive but once you have it, it's quite fast
carmine mica
well anything, calling methods, getting fields, setting fields, anything can be jsut as fast
If you use the java.lang.invoke api with MethodHandles and those method handles are created and stored in static final fields, the is pretty much no difference between that and just calling the method, getting the field, etc. normally.
echo basalt
Reflections are also used when dealing with nms because you aren't doing imports directly
inner mulch
Okay, so that does mean my code isnt doomed perfomance-wise for using normal instances of classes to acces their methods?
carmine mica
if you can use objects normally, just do that.
inner mulch
So accesing methods from another class isnt slower than implemneting it directly into the method?
inner mulch
Reflections are also used when dealing with nms because you aren't doing imports...
Thank you, for you brief explanation of Java reflection :)
inner mulch
well anything, calling methods, getting fields, setting fields, anything can be ...
Thank you too
echo basalt
Nothing beats an object getter in terms of performance
Avoid reflections and use it if you get desperate :p
wet breach
So accesing methods from another class isnt slower than implemneting it directly...
no
in fact, an overly large class can be slower then if it were split up
carmine mica
Nothing beats an object getter in terms of performance
MethodHandle doesn't beat it, but its just as fast if you store the MethodHandle in a static final field
gotta be a static final field tho, can't create them dynamically
echo basalt
There's still the overhead of having to fetch the method
inner mulch
I dont really understand what you guys are talking about
wet breach
well you asked
carmine mica
there's just different reflection APIs in java, the classic reflection and MethodHandle
inner mulch
in fact, an overly large class can be slower then if it were split up
I only understood this part
wet breach
now you are getting answers that are way above your level of understanding š
echo basalt
Yeah maybe you should understand the questions you're asking about
inner mulch
there's just different reflection APIs in java, the classic reflection and Metho...
MethodHandle?
I use this to get methods Main.getinstance.getclass. getmethod?
Is this bad?
echo basalt
What's the point if you can make a getter instead?
carmine mica
you shouldn't be using any reflection to get something in your own class like that
just add a method to get what you want
echo basalt
Reflections are made to access classes you don't have control over
(or to parse annotations)
wet breach
or in the rare circumstance, the micro optimization to bypass some thing
inner mulch
I use this to get methods Main.getinstance.getclass. getmethod?
so this = bad
echo basalt
Pretty much
inner mulch
In terms of clean Code or Performance?
echo basalt
or in the rare circumstance, the micro optimization to bypass some thing
bypass that defensive copy
echo basalt
In terms of clean Code or Performance?
both
inner mulch
So i shiuld be using getters?
echo basalt
Yeah
It's basic java
Don't try to be smarter than you are, just stick to the traditional methods and you'll go far
There's a reason you don't see reflections for every getter in enterprise code
inner mulch
Don't try to be smarter than you are, just stick to the traditional methods and ...
Im not doing anything, this is the only method i knew to get methods from other classes
echo basalt
You still need an instance to invoke it
And if you have an instance and control over the class why not make a getter in the firs tplace
inner mulch
I dont really ever used getters because i got this
echo basalt
Yeah pretty much
inner mulch
If I use getters why is my getter Bad š
echo basalt
Because what you think is a getter is in reality an overcomplicated Field#get(instance) method
wet breach
But yeah sticking with basics though is generally sufficient for most things and is adequate enough
without resorting to some weird method of doing things
you should only change how you are doing something if only its a problem identified from testing and profiling
inner mulch
I mean its not a problem i was just worried that it is ineffiecnt
wet breach
well it is or can be because it isn't providing you with any advantage doing it that way then from the normal way
echo basalt
premature optimization moment
We should just switch to c++, java's too unoptimal
Still waiting for the day we have dedicated minecraft server hardware
wet breach
lol, I wish it would be so easy to have some people switch to C++ just to show them the beauty of java in how it optimizes your stuff quite well
because in C++ its left to you to optimize but it also won't tell you where its not optimal either
if it works, C++ is happy with it as much as you are
echo basalt
TBH profiling in java can get pretty cumbersome
I paid 100$ for a PERSONAL 1 year license for yourkit
all the enterprise stuff is in the thousands
wet breach
yeah but like its so much better then trying to profile a native application though
inner mulch

But, for collections, make sure to return an immutable version or a defensive copy

This is what im doing, but just in the main class??
echo basalt
In every class
Main or not
It's part of the Encapsulation principle
Where you never expose internal values directly
wet breach
literally it is impossible to not use a getter in Java
echo basalt
But instead make the values private and expose get/set methods as you wish
You end up having better control, such as returning a copy or only allowing non-null values to be set
And also get to follow basic code principles (yipee!)
wet breach
so at the most basic level, a getter is just a method that gets something, whether it be a value or an object or instance etc.
echo basalt
In the most basic terms, in java everything is a method, unless it's a field or a constructor
wet breach
The reason you see guides explain this a bit differently is because typically people have an issue in regards to using getters for collections or similar where you are not using such methods in a way that is pointless
inner mulch
I dont think my getter is that bad its just that i can acces it from every class and dont need to get it everytime i want to use it
echo basalt
This is a method:
public/private/protected <Insert Return Type Here> methodName(Param1Type param1Name ...) {
// implementation
return /*<Return type, or nothing if it's void>*/;
}
What is commonly referred to as a "getter" is just a method that returns a field directly
wet breach
I dont think my getter is that bad its just that i can acces it from every class...
the purpose of your getter isn't what was the issue it seems, it was how you were implementing it
echo basalt
public int doWhatever(String input) {
return input.length();
}
Is a method, of public accessibility, with the return type int, named doWhatever, where the first parameter is of String type and called input
So we must return an integer
inner mulch
Ik what methods are
echo basalt
So you understand that a basic getter is just a method that returns a field's value
wet breach
well just know what you are asking or having some confusion over is basic java stuff
inner mulch
So you understand that a basic getter is just a method that returns a field's va...
Yes
I have a getter in a class
echo basalt
Alright
Can we also agree that it's the most basic form of method, as it holds no logic other than just returning a value
inner mulch
Yes i have somthing like this
I understand the concept but i dont know what wrong about Main.getinstance.getclass.getmethodfromotherclass
wet breach
Main.getinstance.getclass.getmethodfromotherclass if the method that you really wanted is in a different class, then why are you not calling the method from that class directly? Why go through the main class?
inner mulch
You are correct, but i got tired after doing this over and over again from class to class, so that i just get it from mainclass
wet breach
This breaks OOP fundamentals which is what Java is primarily for. This is more inline with how functional programming is.
inner mulch
OOP?
wet breach
Object Oriented Programming
inner mulch
It breaks the OOP, but my code doesnt break, whats the problem with it?
echo basalt
Stick to standards
wet breach
I mean yeah the code works, just it isn't appropriate or correct is all lol. Java excels at doing Object oriented stuff, its what it is primarily designed to do. This isn't the say that using functional programming is inherently slower, unoptimal or whatever else but it could be depending on what you are doing and more easily. Java does a lot better if you stick with object oriented programming, even more so when it comes to stack traces or errors. If you call a method like you are and it returns an NPE, the stack trace is going to contain unnecessary entry/exit points of the overall execution that resulted in the NPE. There is many other reasons such as standards as well in why the way you are doing it isn't correct.
inner mulch
why is it incorrect, if it isnt slower or unoptimal? And it works
echo basalt
Welcome to code architecture
inner mulch
I know the standards
echo basalt
No you don't
inner mulch
No I know (bacause of) the standards
echo basalt
The standards aren't made as a "because I said so"
inner mulch
What?
echo basalt
They serve a purpose
Their goal is to make you write code that's more reusable, easier to test and enforces ownership
When writing a class think "Is this function supposed to be the duty of this class?", will help you avoid writing crazy functions for data objects that should belong elsewhere etc
inner mulch
When writing a class think "Is this function supposed to be the duty of this cla...
Im not importing all of the classes into one, only the ones i need
wet breach
why is it incorrect, if it isnt slower or unoptimal? And it works
because it uses reflection and yes it can end up being more slower or unoptimal. By how much? Well it really depends on the code being called in that way. Granted for the most part you probably wouldn't notice the difference, but do note the JVM has a more difficult time optimizing reflection, then if you were to just stick with the standard way of doing things.
echo basalt
If you were to port your entire project to bungeecord, how big of a percentage would need to be re-done? That's a basic example on code re-usability
inner mulch
I never used bungeecord
wet breach
however it seems pointless though that you keep asking why it is wrong when it is clear your reasoning is because you want to be lazy and ignoring anything else in regards to what is being explained. That is fine, however that isn't justification in whether it is the correct or wrong way of doing things, just you don't want to go through the appropriate coding etiquettes.
inner mulch
I would change it, but only if there is evidence that this is perfomance wise worse

just like what was stated, there is more to programming then just performance. It has already been explained to you how it could be less performant as well and that you may not really notice the difference. How you choose to program is up to you, but when you ask however in why it is wrong and others here explain to you why it is. You shouldn't dismiss the explainations all because you don't notice a performance difference. I am not going to go out of my way to create a test application to show you the difference because you want evidence. In large part, the majority here who help are not going to lead you astray or purposely tell you false information and quite a lot of us are very experienced in the programming field.

You can customize the Deathmessage to your liking by adding an EventListener for PlayerDeathEvent.

Someone help me please
chilly hearth
how ?
chilly hearth
Idk where that script is from
thats from buildtools page ;-;
young knoll
Download the jar, open command line and run java -jar BuildTools.jar --rev 1.20.1
chilly hearth
command line ?
hybrid turret
type cmd in the search bar
hybrid turret
then you navigate to the folder where the BuildTools.jar is using cd <path>
then you execute the command above
in order for the cli to find the jarfile you need to be in the folder or add the absolute path

alr

i was in worldguard region lol
see plugins interact weid if not designed together. If my plugins break cuz of some worldguard itd be like tough luck lol
hybrid turret
does it make sense to have saveDefaultConfig() in both onEnable and onDisable?
smoky oak
not really, it writes the included config if it doesnt exist
if its not there on disable you have other problems lol
hybrid turret
oh okay lmao
Is there anything (except for some message) that makes sense to put into onDisable?
smoky oak
tons
mostly all the data you need to still have next time
but cant save immediately after you access it
hybrid turret
for example?
smoky oak
for example if you do something that constantly changes. If you make custom behaviour for stuff
hybrid turret
hmmmmmm

guys why does an event on if(ageable.getAge() == ageable.getMaximumAge()) is being called even though the nether wart is only at stage 2? (it works at stage 3 too, but below 2 it isnt called as intended)
hybrid turret
also if you save anything in files, you shouldnt do it on every change
couldnt that lead to data loss tho?
hybrid turret
well, true
would it make sense to have some async timer running that saves everything after some time?
or could that be l a g?
smoky oak
eeeh async data is difficult to design properly
it may lead to corruption if you dont lock it, at which point you might as well spare yourself the headache
hybrid turret
tbh best for me to stay away from that anyway, never worked with async
If I have something like a /back-command what is the best way of storing, using and then deleting the locations for that?
I have it working right now but only using a file where the locations are constantly saved everytime a player dies and is then deleted once the player uses the command.
hazy parrot
There won't be concurrency if it won't be accessed at same time from multiple thread, hence no needs for lock
hybrid turret
And I feel like with a lot of players that would be slow asf

smoky oak
uh you could just keep it in a player list too
i dont think this needs to persist over restarts
hybrid turret

oh ty
also: i have a command that uses nametags as a key. this key can sadly be renamed or used on entities though and therefore destroyed, which will effectively lead to staff having to restore keys constantly which would be stupid.
how to i prevent players from changing the displayname, crafting with it and using it except for on doors?
young knoll
Why does renaming it mater
smoky oak
use the item uuid
hazy parrot
^
hybrid turret
changing the name technically doesnt matter
young knoll
As for crafting you can use the PrepareItemCraftEvent
For using in mobs there is PlayerInteractEntityEvent
Thereās also InventoryClickEvent to handle villager trades
hybrid turret
it's just it's a special name which you can't get again and you get more than one key to give to trusted people.
what's not working is the EventListener for the key being used.
The rest is stuff that came to my mind while writing the question lol
young knoll
?notworking
undone axleBOT
"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.
hybrid turret
sorry lol
hold on
What's the difference between PlayerInteractEvent PlayerInteractAtEntityEvent and PlayerInteractEntityEvent??
young knoll
First one is for interacting with not entities
Second one is special and is only really useful for armorstands
Third one is for interacting with entities
hybrid turret
oh-
smoky oak
note
smoky oak
right clicks on air with no items dont trigger the interact event

guys since when is sugar cane ageable?
young knoll
Since always afaik
shadow night
It always was

Yeah, when it reaches max age it grows a new cane on top

Once the state reaches the max value then it tries to spawn a new block

not the right command ig lol
thought it was
found it
What is the proper way of getting an OfflinePlayer, since Bukkit.getOfflinePlayer(String name) is depracated?
I mean it totally makes sense that it's depracated since you can change your name and if you're not on the server a different player could have taken that name.
But how do I get the UUID if I want to e.g. add a whitelist override? (so i only have the name from args)

Hey I updated the server to 1.20 and now I always get an error when waterfall is executing the proxyplayer.chat() function: java.lang.UnsupportedOperationException: Cannot spoof chat on this client version!
So far only one has mentioned this issue a year ago but so far I can't see a fix or workaround for that.

It's not possible did you read what md5 said

If you store the name sure just use the uuid once you get the offline player

yeah but why is the function still present in the latest version if its not possible to use it since a year? Shouldn't it be deprecated or removed entirely?

Make an issue or post on that issue about it
hybrid turret
If you store the name sure just use the uuid once you get the offline player
So I store every player onJoin? Sounds like a waste of resources
river oracle
Don't store the entire offline player object sounds like a waste why are we not comparing uuids in your system all it takes is comparing uiids once you get the offline player var

Found out why it's not deprecated
hybrid turret
Wait, I think I donāt get how the OfflinePlayer works
river oracle
Bungee supports 1.8-latests natively thus the api works for those versions natively depreciating it for
river oracle
Wait, I think I donāt get how the OfflinePlayer works
It'll query mojangs servers if the players never logged on iirc
I'd have to recheck stash but I believe that's what's done
hybrid turret
Okay so i can loop through that checking for the uuid but how do i get the uuid from my system?
river oracle
Why would you loop and not use a hash set
hybrid turret
Uhmmmm tbh maybe iām dumb lmao guess i donāt have as much java knowledge as i thought

You'll need some form of data storage whether it's a database json file etc to verify bypasses
Then use a hash set instead of an array list
In your java code to store those players uuids
pseudo hazel
yes but for only like 100 players it generally doesnt matter
but using a set in this case is also just cleaner
pseudo hazel
like the performance difference can be ignored
river oracle
It does matter using proper data structures for a job should be something you just do
sand lion
It should be a new item (same material as passed in), but with a new meta
sand lion
yes
pseudo hazel
otherwise the meta will not be updated regardless
hmm, maybe the meta doesnt work for recipe outputs?
idk I never made recipes

Yeah json is also a thing i would love to understand in java but it just never works lol
pseudo hazel
json is super easy, yml even easier and both are pretty much baked into spigot or java
you can use the gson library for json stuff

I would not know sorry

Yeah thatās what makes yaml so easy lmao

Iām not sure if i mentioned this already but i have no idea about hashsets

what do you hate about yml
Structure and how the files look. Itās so ugly
Json is so much better
