and multimap should be the one you are looking for
#help-development
solid forge
tender shard
ah okay, but MultiMap returns a collection
glass mauve
isnt it multiple values for one key?
tender shard
so a MultiMap is nothing more than a Map<K,Collection<V>> I guess
solid forge
isnt it multiple values for one key?
multiple same keys multiple values as i remember
idk
seldom used it
tender shard
isnt it multiple values for one key?
yes exactly
solid forge
bump
is the registerintent and completeintent in bungeecord async or sync?
tender shard
but it doesn't implement Map anyway so I can just ignore it
but for real, why would someone store null<>something in a map
did you ever see that in real life?
I mean I understand null as values, but null as key? why?
glass mauve
null as key makes no sense lol
tender shard
yeah exactly lol
solid forge
just like the whole idea of NFT ooooooooo
tender shard
I'll just throw a RuntimeException when someone uses null as key
and if they use null as value and the map doesn't support it, so be it, then it's their problem
solid forge
can just use an optional wrapper for it?
tender shard
nah you don't know what I'm doing, one second
this allows you to pass any kind of Supplier<Map> to use it inside a PersistentDataContainer
people might now save a HashMap which allows null into a PDC
then later they read it again using aTreeMap, which does not support null
I don't know whether the map they passed supports null as values, though
since everything's 100% generic
tender shard
someone above mentioned that it doesn't
I haven't checked it
but yeah if someone saves a map with null and then loads it again as a map that doesn't support that, it's their own fault anyway, so I shouldn't worry about it
does someone know whether I can get rid of the ugly (Class<C>) cast in the 4th line from the bottom?
public class CollectionDataType<C extends Collection<D>, D> implements PersistentDataType<PersistentDataContainer, C> {
private static final String E_NOT_A_COLLECTION = "Not a collection.";
private static final NamespacedKey KEY_SIZE = getValueKey("s");
private final Supplier<? extends C> collectionSupplier;
private final Class<C> collectionClazz;
private final PersistentDataType<?, D> dataType;
public CollectionDataType(@NotNull final Supplier<C> collectionSupplier,
@NonNull final PersistentDataType<?, D> dataType) {
this.collectionClazz = (Class<C>) collectionSupplier.get().getClass();
this.collectionSupplier = collectionSupplier;
this.dataType = dataType;
}

how do I make two checks at the same time with Player interact event, mainhand becomes air when off hand check is being done during the second fire

tender shard
I think above method is correct
I only want it for that statement though, and the javadocs say "@ SuppressWarnings" can also be used on local vars, so I am confused on why it's not working
tender shard
yeah, they also say it should work, that's why I am confused lol
glass mauve
bruh maybe problem with IntelliJ
crisp steeple
it works for me
tender shard
weird
glass mauve
restart IntelliJ 😄
tender shard
oh wait
it's probably
because I am not assigning a local var
it's a field assignment
glass mauve
yea
tender shard
not working

is there a better way of doing this check?
if (Math.max(abs(loc0.getBlockX()), abs(loc1.getBlockX())) - Math.min(abs(loc0.getBlockX()), abs(loc1.getBlockX())) == 1){
tender shard
what is that even supposed to do?
sharp bough
get the diff of the absolute values of two X coordinates
public boolean locsAreAdjacent(Location loc0, Location loc1){
if (Math.max(abs(loc0.getBlockX()), abs(loc1.getBlockX())) - Math.min(abs(loc0.getBlockX()), abs(loc1.getBlockX())) == 1){
System.out.println("diff is 1");
}
// same for Y and Z if theres two 0 and one 1 then block is adjacent
return false;
}
something like that
tender shard
get the diff of the absolute values of two X coordinates
int x1 = block1.getX();
int x2 = block2.getX();
int distanceX = Math.abs(x1 - x2);
this?
glass mauve
yea thats the same
sharp bough
nah nvm im just gonna keep what i did
glass mauve
y
sharp bough
it just looks ugly
tender shard
your version is so complicated
I don't even understand what you're doing there
just do x1 - x2 and then turn it positive if it's negative
done
glass mauve
just do:
if (Math.abs(loc0.getBlockX() - loc1.getBlockX()))
sharp bough
that would fail if locations are -20 -21
tender shard
no
glass mauve
no
sharp bough
what abt -20 21
glass mauve
and -21 - (-20) = -1 and Math.abs(-1) = 1
sharp bough
it would return 40
tender shard
what abt -20 21
that would return -1
that's why we put it inside Math.abs
so it would also return 1
sharp bough
-20 - 21
tender shard
guess what: also 1
your code is bloated and prone to error, the code we sent will work 100% guaranteed
glass mauve
it would return 40
yea it would return -41 because the diff is 41
tender shard
into Math.abs = 1
tender shard
yea it would return -41 because the diff is 41
oh he meant x1=-20 and x2=21?
glass mauve
yea, still works
tender shard
it will work in every possible case
I also don't get why they ask "is there a better way", then we tell a way better way and then they just say "ugh I'll just stick to my weird version"
why did they ask then, anyway

is there a way to hide a command from autocomplete and make it look like its an unknown command
waxen plinth
Commands should act this way if the sender doesn't have permission by default
nimble torrent
how do i make a command have permissions?
waxen plinth
Or at least, they shouldn't appear as a tab completion if the sender doesn't have permission
commands:
example:
permission: permission.node.here```I watched this one: https://www.youtube.com/watch?v=jytF-6WD2Eo&list=PLfu_Bpi_zcDNEKmR82hnbv9UxQ16nUBF7&index=10
waxen plinth
I wouldn't bother with the default commands though
They suck
I guess if you're a beginner you should learn how to use it
But as soon as you understand it and feel comfortable with it you should abandon it in favor of a framework
warm light
I tried this. still same
waxen plinth
Ok again you're adding the original item, not the modified one
warm light
.-.
waxen plinth
rename probably returns a new item rather than modifying the instance you gave it
crisp steeple
I tried this. still same
If LivingEntityHead.BEE is a static field, then it’ll use the same itemstack every time this happens

commands:
example:
permission: permission.node.here```
is ther away to have permissions but ignore them if its a certa in player?

Why would you ever want that
Just set up a proper permissions plugin

Or op yourself lol
warm light
Itemstack.rename working fine. problem with NBT
waxen plinth
Don't make backdoors
waxen plinth
``Itemstack.rename`` working fine. problem with NBT
No it's not a problem with NBT
It's that you're creating an NBTItem and then doing nothing with it
You're applying a property and then you don't even use it
nimble torrent
Don't make backdoors
the owner wants me to make this :/
nimble torrent
ok
waxen plinth
There is no reason to create user-specific backdoors
nimble torrent
waht is a backdoor
crisp steeple
@warm light can you show where the code for LivingEntityHead.BEE is?
waxen plinth
A hidden bypass
nimble torrent
oh like popbob
waxen plinth
<@!726439170460876840> can you show where the code for LivingEntityHead.BEE is?
That's not the issue here
warm light
Already fixed. I am dumb
waxen plinth
The issue is that you are creating an NBTItem, setting a property on it, and then doing nothing with it
warm light
have to use getItem() there
waxen plinth
Yes
I'm not familiar with the NBT API
But it makes sense that you have to get the modified item from it
I wouldn't expect it to mutate the item it's constructed with
crisp steeple
That's not the issue here
Well yeah, but if it’s trying to use the same itemstack everytime that’ll also end up being an issue
waxen plinth
It won't if you're creating copies
crisp steeple
Doesn’t look like it is though
waxen plinth
It looks like rename might
But NBTItem doesn't
I'm guessing Itemstack.rename is something they made themselves because it's poorly-named with bad default behavior
crisp steeple
Even if rename does though it’s not getting stored in a new variable
waxen plinth
I would recommend renaming it to something like ItemUtils and having it return a copy of the item with the new name rather than renaming the instance that's passed
warm light
okay
waxen plinth
Yeah if you change this behavior then you'd need to call rename and then store the return value
warm light
it don't return anything just get itemstack from input and rename it
waxen plinth
Yeah and I'm telling you to not do that
public static ItemStack rename(ItemStack item, String name) {
item = item.clone();
ItemMeta meta = item.getItemMeta();
meta.setDisplayName(name);
item.setItemMeta(meta);
return item;
}```Then you'd do something like this
ItemStack something; // assume this is populated
something = ItemUtils.rename(something, "name here"); // creates a copy of the item with the given name```Pure function
warm light
okay. thanks :D
waxen plinth
👍
In general you should try to write your utility functions so that they take in values and return other values without modifying the input
If a function doesn't modify its input or any sort of internal or global state, then it's called a "pure function"
They're preferable because side effects (modifying parameters and state) make things more complicated and are harder to test

Is it wise to save every player who ever entered the server into my cache (concurrent hashmap)? I'm debating whether I should load every playerdata from my database on server startup or just retrieve them at the time they're needed or called

Retrieve them when they join
neon nymph
Yea, that's what I'm doing, then I save it to my database after a specified amount of time. Then in the next startup, should I preload their data from the database or just retrieve it again on their join or when it's called (used in commands and such)?

The head just defaults to a steve or alex. The player never joined the server I dont know if thats an issue
The only way it works is with

SkullMeta skullMeta = (SkullMeta) minerHead.getItemMeta();

The Liskov Substitution Principle states that any subclass object should be substitutable for the superclass object from which it is derived. This semantic relationship often called behavioral subtyping, is applied to develop more correct, extendable, and reusable software.

ArrayList -> if you need to access something via index
HashSet -> if you need to check if an element is contained in the collection fast
LinkedList -> basically everything else
glossy venture
i like to do
ArrayList<V> linear;
HashMap<K, V> mapped;
Yes but HashSet presupposes few hash collisions as possible if you want it to be truly fast
glossy venture
for anything that needs to be iterated over but also needs quick lookups
cosmic pelican
LinkedList also allows for index based access
I know
ArrayList is slower than a LinkedList
cosmic pelican
In terms of?
appending
cosmic pelican
yes.
ivory sleet
no lol

an ArrayList needs to free up space in the array for an element

then why wouldn't you just use an array?
ivory sleet
But even then resizing is extremely fast since it uses system::copyarray which is natively implemented
cosmic pelican
If you know the size there is no point
ivory sleet
then why wouldn't you just use an array?
Because ArrayList allows you to resize the array
maiden thicket
wat
ivory sleet
no that’s not what it’s about
glossy venture
iteration, getting by index
ivory sleet
Initial capacity is a good pre-optimization
glossy venture
anything that needs to be ordered
maiden thicket
oh for hashmaps getting by index?
ivory sleet
If you know approximately the amount of elements the array list will have on average
glossy venture
and then do
public void register(Identifiable it) {
mapped.put(it.getIdentifier(), it);
linear.add(it);
}
Then setting initial capacity can reduce conceivable resizing operations you might have to go through
glossy venture
neglecatble and if i need to iterate over something its much faster
cosmic pelican
LinkedList internally maintains doubly-linked lists which store the memory address of previous and next object, so there will be no kind of structure which will keep memory address of the previous node and next node. There is no initial capacity defined for LinkedList, and it is not implementing a RandomAccess interface. LinkedList is faster than ArrayList while inserting and deleting elements, but it is slow while fetching each element.
cosmic pelican
@faint sage would do better in this conversation than I would but he's offline atm.

Yes but we were talking about add/prepend specifically
LinkedList is faster than ArrayList while inserting and deleting elements
glossy venture
that exists?
ivory sleet
Bruh
glossy venture
ah lmfao
ivory sleet
Like, I already told you
ArrayList can be faster than LinkedList if you have set the initial capacity
Literally
cosmic pelican
and when it goes past that initial capacity it isn't
ivory sleet
Yes but to some extent if you’re reasonable you’ll be able to predict it thus array list is reasonable even if you add and remove elements frequently
And also insertion by index is quite fast for ArrayList
glossy venture
it stores the nodes anyway
so it really doesnt save memory
saves like 4 bytes per pair

for linear, ordered access and fast lookup access

ivory sleet
LinkedHashMap is sort by value with a linked data structure order (can be both by access and by insertion), TreeMap is sort by key with a tree structure order (ofc it’s possible to still sort by value)
Actually it might be the other way around
maiden thicket
ive never touched linked anything cus tbf ion know how they work loll
or why u would use them

Mye it’s the damn other way around

yes i dont get why that has to do anything with the fact i dont use linked shit

All the integer keys in an ArrayList must be positive natural numbers where each number is consecutive
and it uses int not Integer :3
unreal quartz

They are very different structures
ArrayList is an array which gets copied over into a bigger one when it is full, HashMap uses linked list buckets identified by the hashcode of entries to store its values

So you want to check whether there's at least 1 duplicate?

yea

What are you trying to do with server version?

Hey,
How would I overwrite the bukkit permission system?
In java 8 times, I'd just replace the perm field with a custom one, but I can't do that with Java 17, because it's final
warm light
if (server version >= 1.14.4){
register a event
}
summer scroll
if (server version >= 1.14.4){
register a event
}
You can use String#contains, so Bukkit.getVersion().contains("1.14")

Hey,

In java 8 times, I'd ...
You could take a look at how LuckPerms does it
warm light
You can use `String#contains`, so `Bukkit.getVersion().contains("1.14")`
but event wouldn't register in 1.15+
summer scroll
Oh you want to check If the version is greater or equals than
warm light
Yes
summer scroll
There is no easy way, you need to get around with the value from Bukkit#getVersion
warm light
thats also string

However I found a lib created by mfnalex, here's how he did it.
https://github.com/JEFF-Media-GbR/JeffLib/blob/89dfd7941e6ae879d4af70f9ba1c5fe8790d4ac8/core/src/main/java/de/jeff_media/jefflib/McVersion.java#L62
sage dragon
You could take a look at how LuckPerms does it
And there's the confusion... Even though the field is final, it just uses setAccessible and is done with it
summer scroll
And the example usage
public static void registerBlockTracker() {
if (McVersion.isAtLeast(1, 16, 3)) {
Bukkit.getPluginManager().registerEvents(new BlockTrackListener(), main);
} else {
main.getLogger().info("You are using an MC version below 1.16.3 - Block Tracking features will be disabled.");
}
}
umm, I guess I can replace the r with null and cast to long. then check?
young knoll
And there's the confusion... Even though the field is `final`, it just uses `set...
Final is fine to replace with reflection
As long as it isn’t static final

I usually use EntityDamageEvent or something like that

sure, that works too. doesn't really matter whether it's an event or a runnable as it doesn't do anything besides dividing two numbers 😄

if i wanted to display a actionbar longer than a few ticks, would i need a runnable?
or is there another way?

then use repeating task to set the progress to (mobCurrentHealth / mobMaxHealth)

currentHealth / maxHealth will always be a value between 0 and 1
e.g. 50% health out of 40 max health will be 20/40 = 0.5

Hi! I'm running a paper server and I want to make new entities that behave like villagers (namely a villager that has the model of a pigman and a villager that looks like a player character but without replacing any original villagers). How would I achieve this the easiest? I'm not sure if this can be done with some /summon shenanigans but so far I'm stumped. Could this be easiest done as a plugin? Should I make a forum post instead?
pliant oyster
currentHealth / maxHealth will always be a value between 0 and 1
so u dont need to set the max?

no, you always set the bar to (currentHealth / maxHealth)

Bukkit.getLogger() is a thing I think
tardy delta
whats even te difference between those two loggers?

a lot
Bukkit is the generic logger, the plugin logger is the plugin-specific logger
the better question would be why one would need the logger in the first place

Always use your plugins logger where you can.
tardy delta
why is it even possible to access the bukkits logger then?

Bukkit being bukkit

Because it's a public field that they can use in their classes

using the server's logger can generate tick issues with large amounts of log spam

I imagine the same would be true for the plugins logger
viral crag
not necessarily
you can run your own logger on a separate thread

vocal cloud
I mean you can but you really really shouldn't be logging that much

why is it even possible to access the bukkits logger then?

When I am running a piece of code to spawn in a npc I get an error saying CraftServer can't be cast to MinecraftServer but when I change it to not have that, it brings up saying CraftWorld can't be cast to WorldServer. Even worse is after even fixing that it still errors but this time with no stacktrace just an error saying the same line is causing an error.
EntityPlayer npc = new EntityPlayer((MinecraftServer) player.getServer(), ((WorldServer) player.getWorld()), new GameProfile(uuid, name));

how do i check if a string in an array doesnt exist since if (args[2].isEmpty()) doesnt work
eternal oxide
if (args.length > 0)
shy saffron
oh yeah true
craggy sapphire
you can fix it yourself if you want to use it: https://www.spigotmc.org/threads/...
i am trying to compile it but eclipse is saying no projects found in that repo
shy saffron
alright it works now thanks
viral crag
i am trying to compile it but eclipse is saying no projects found in that repo
you likely need to setup maven or gradle
quaint mantle
the index is 1 right?
0
iron tundra
How do i get the first entry in a list?
it starts at 0 also FindFirst is a thing
craggy sapphire
you likely need to setup maven or gradle
how do I do that?
viral crag
how do I do that?
start by figuring out which one the project uses and get those plugins that eclipse needs
craggy sapphire
how do i figure out which one the project uses?
eternal oxide
Eclipse comes default with both
iron tundra
how do i figure out which one the project uses?
You could use IntelliJ instead of Eclipse
IntelliJ sets it up automatically
craggy sapphire
okay
viral crag
how do i figure out which one the project uses?
is there a pom.xml file?
viral crag
then it is likely gradle and you will have a build.gradle file
viral crag
hmm nope its a bare java
craggy sapphire
after I have IntelliJ how do I compile it?
midnight shore
Hi, i was wondering how could i make a sort of entry for a Constructor that will define what will happen to the selected entry whenever its picked. As you can see i'm doing a queue system
like a Consumer but i don't really know how do they work
tardy delta
?
midnight shore
how do consumers work? could you help me please?
viral crag
is that supposed to spell plugin?
iron tundra
after I have IntelliJ how do I compile it?
You click the run button to compile your code
craggy sapphire
You click the run button to compile your code
bruh IntelliJ is paid so i gotta buy it before i can compile
im just looking for smth
to compile the plugin
once
and be over with
viral crag
bruh IntelliJ is paid so i gotta buy it before i can compile
you get the commercial version or something?

a consumer is something like
Consumer someConsumer = event -> {
System.out.println(event.getPlayer().getName());
}
void onEvent(Event e) {
someConsumer.accept(e); // will execute the sysout stuff
}```I'd like having a system that has multiple entries and a runnable that every 25 ticks takes the first entry of the list do some stuff (and i want to specify this. How can i specify a list of code that will happen when an entry is selected?) and then removing that entry.
For example i have a list named PLAYERS_TO_WARP and every 25 ticks it takes the first entry of the list and warps it to the hub. My question is: How do i specify this last thing? How do i specify that the players will be teleported to the Hub?
hope its clear
tardy delta
or if you write it like this
Consumer<Event> someConsumer = new Consumer<>() {
void accept(Event event) {
System.out.println(event.getPlayer().getName());
}
}```stack
grim ice
how do consumers work? could you help me please?
basically
e.g pass a consumer to someone
grim ice
then do consumer.accept(<T>)
viral crag
i have absolutely no idea of how this work
eternal oxide
On the github page for the project, click the button marked "code". Then click the copy to clipboard button for the URL.
In Eclipse File menu -> Import.
Expand the Git entry, and select Projects from Git (with smart import).
click next and select Clone URI in the next menu.
Click next and everything should be filled in for you.
eternal oxide
Click next and it should be imported
grim ice
itll run the code in the consumer
iron tundra
Create a new project
craggy sapphire
