Another pretty obscure example would be https://github.com/Geolykt/Presence, where the API classes are located under de/geolykt/presence/common. It has absolutely no interfaces but was built as an API (while also serving as the implementation of the API) strictly speaking. In the end an API can be everything you want as long as you document it

Why is it when i edit tripwire blockstates, the player sees the wrong blockstate until they relog?
quiet ice
Well, to continue the example of bukkit, it stores an instance of Server within the Bukkit class. (CraftMain (I think it was called that at least) sets it after it constructs the CraftServer class, which implements the Server interface)
The CraftServer class and co do not need to be exposed within the API and ideally should be in a seperate repository, but that can be difficult to maintain which is why I do not do it
However if you make an API ontop of bukkit and want other people to register implementations of it, use Bukkit's service API which more or less does the same thing just that you only need the interface class. For example the vault api only needs to provide Economy but not any holder class as that is already done by the service api
sterile token
Hmn you probably no understanding me or im not explaning good
tardy delta
but all blocks in an event will have a nonnull world for the location right?
blazing scarab
Yeah
hybrid spoke
quiet ice
it wont go null
hybrid spoke
if anything refers to the location, it also implies the reference to the world
but there is this ugly #setWorld method
quiet ice
If you obtain your location from bukkit, you will always get a non-null values
hybrid spoke
where you can null the world yourself
tardy delta
meh
tardy delta
so theoretically it should never be null
quiet ice
And as per javadocs, it will throw an exception if it is unloaded
hybrid spoke
if the world is unloaded but accessed, there will be an IllegalArg thrown
brave sparrow
~~so theoretically it should never be null~~
It’s supported if a plugin wants to make it null but if you’re getting it from spigot it won’t be null

why people use base64 for encoding binary data to ascii strings instead of OutputStream#toString() method?
wouldnt use of toString() method result in smaller lengths of the string
base64 on average increase the file size by more than 25%
for example this byte array
byte[] = new byte[]{65, 66, 67};
could be decoded to
ABC string
drowsy helm
when you're working with small objects, 25% doesn't really matter
minor otter
When editing blockstates the client will try to predict what it should be and will show something it isn't, how do i go about updating this?
mortal hare
well base64 is used for places where ASCII could be used
and to prevent bugs with weird characters, for example newline characters
since ASCII has over 20 control characters
and its "signed" charset (127 chars), thus there's no way to fit byte values above 127 without encoding separately in ASCII (unless we use extended charsets, like UTF-8)
maybe that's why
i think i answered myself lol 😄
onyx fjord
🥲
mortal hare
Its just so annoying that ASCII doesnt hold 255 values
and instead it holds half
you wouldnt need any encoding then (if you werent evading bad symbols)

am i blind or am i not seeing difference between ObjectOutputStream
and BukkitObjectOutputStream
it just extends the ObjectOuputStream class
and adds in one method
but inorder to write to the stream we use super method
of ObjectOutputStream
nvm
it overrides
@Override
protected Object replaceObject(Object obj) throws IOException {
if (!(obj instanceof Serializable) && (obj instanceof ConfigurationSerializable)) {
obj = Wrapper.newWrapper((ConfigurationSerializable) obj);
}
return super.replaceObject(obj);
}
to add in support for bukkit object deserialization

try changing the type of byte[] to Byte[]
mortal hare
Hi, @Nullable has TYPE_USE target, it's applied to the array element type, not to the array type itself. To annotate the array type with the TYPE_USE annotation, use byte @Nullable [] bytes syntax.
solved
although i never seen a dude
who annotates like this
byte @Nullable []
that's weird
quaint mantle
horrific
mortal hare
horrific
you're not the one, who thinks this way:
But don't you think it's weird to declare an array this way?
Can the IDE be more intelligent in recognizing primitive arrays？
that makes sense
byte @Nullable []
byte type inside of a Nullable array
but i'd like a different syntax
i dont know what that would be though

really random and ik you're all probably gonna get mad at yell at me and probably start screaming at me saying "learn java" knowing this community,
But how do you get a player variable in a gui? I've tried a ton of things but apparently none of them wanna work, So i was wondering on what the hell im doing wrong
manic crater
🤷
I tried casting player to the code but apparently that doesn't wanna work
i tried google apparently that has no info,
meh
dawn hazel
is it a hashmapped or something variable?
manic crater
For instance i wanna check if this is false or true:
"Quests." + p.getUniqueId() + ".Ore Miner Status"
But apparently its the p.getUniqueId() issue where it doesn't wanna work ig 🤷 idk it just keeps saying the player is null but yet i have this above all the code in the gui:
Player p = (Player) Bukkit.getServer().getPlayer(getName());
manic crater
ye
sterile token
I dont understand you
manic crater
well the point of the variable is to check if the "quest" in this case was started or not,
So i wanna use a gui to change the item lore if its enabled or not
dawn hazel

Player p = (Player) Bukkit.getServer().getPlayer(getName());``` is above all your codeyou need to define the player in your function

just change this

No need for the casting
ideally from an event is better as coll is saying

Hey so if a returned ItemMeta is null, how am I supposed to set the display name?
brave sparrow
It shouldn’t be null
brave sparrow
As far as I know it shouldn’t ever be null
lavish hemlock
Aight okay then
blazing scarab
It shouldn’t be null
I think it is on air?
brave sparrow
I think it is on air?
That may be the case, but it seems unlikely that they’re trying to set air’s name
I can’t remember if the item itself would just be null if it was air though
I think it would be null
blazing scarab
Well, yeah. Methods in inventory has notnull annotations so i always though they are air all the time
However... They're not

It has not null annotations but it definitely returns null when it’s an empty slot
It’s very strange

is there a way to get which tree leaves are a part of?
blazing scarab
is there a way to get which tree leaves are a part of?
I mean, in minecraft trees are just a set of blocks
They are not identified anyhow
waxen plinth
They kinda are
The game keeps track of how far from a log each leaf block is
You could just find the closest log to a leaf
And that log belongs to the tree which "owns" those leaves
midnight shore
And that log belongs to the tree which "owns" those leaves
Not always… if you create a large oak tree and a small tree near, it would bug out I think
spiral bramble
Stupid question, as I'm using RedLib, I also need to add it as a dependancy and install the plugin on the server?
Apologies I haven't used libraries before, I typically make my own mess
waxen plinth
You can use it in one of two ways
You can install it on your server and add it as a dependency in your plugin.yml
That's the recommended way
Or you can shade it into your plugin's jar via your build system
If you have further questions feel free to join my support discord, it's linked in the readme for redlib and also its plugin page on spigot

Or you can shade it into your plugin's jar via your build system

Unless they're referring to spawn egg items (because of the EntityTag there), in which case I don't think the Bukkit API allows for that because there's really no great way to go about it yet. We don't really have a way to modify the entity spawned in an item stack

i mean, a code can be both long and slow at the same time
If a code is simple and fast it requires no optimisation. If LoC is reduced in optimisation, it then becomes the default way to write the code, giving the illusion that efficiency has an association with longer code if that's what you call optimisation.
