Is there anything specific that you don't understand?
next stratus
I just can't understand how to create a new string what I can send to a player
dusk flicker
I can send u a snippet
eternal night
I mean, the most basic one is just ```java
final Component parsed = MiniMessage.get().parse("<red>A red piece of text");
I'm someone who likes to see how things are done at first
eternal night
tho afaik the wiki is outdated af
dusk flicker
adventure docs are horrible lmao
eternal night
They are just outdated ye
next stratus
So I'm not just dumb?
dusk flicker
eternal night
Well the docs are not optimal but the concept of mini message and the java interface is pretty straight forward
dusk flicker
Exactly what Lynx said
next stratus
I was worried that it was just me being dumb finding this confusing
dusk flicker
no, adventure is just confusing on the first go around
Took me a few days to figure it out lol
next stratus

eternal night
What version of mini message are you using
it went through a bit of changes here and there
dusk flicker
Or what ver of Paper
next stratus
I think i got it
dusk flicker
Assuming you are using Paper, otherwise it might be a nightmare lol
eternal night
e.g. MIniMessage.get was replaced with MiniMessage.miniMessage()
next stratus
String test = "hi";
Component component = MiniMessage.get().parse(test);
?
eternal night
Yes
dusk flicker
Should work ye
dusk flicker
e.g. `MIniMessage.get` was replaced with `MiniMessage.miniMessage()`
when did this happen? Im running the latest paper api and still use the old one
dusk flicker
Nope, not in my pom
eternal night
no, paper also does not use mini message as an impl detail
dusk flicker
If not I got no idea lol
eternal night
something is pulling it in and it definitely isn't paper-api ๐ ยฏ_(ใ)_/ยฏ
next stratus
Sorry, but how do I send this message to the player? ๐
next stratus
I got a component and I don't know how to use it
dusk flicker
With Paper you should just be able to pass it through Player#sendMessage
Spigot would be not so much fun lol
next stratus
is it better to import paper over spigot or?
eternal night
Well thing is you cannot publish a plugin that only works on paper to spigot
next stratus
Will it mess up any of my other code?
eternal night
no
dusk flicker
Is this a public or private plugin?
eternal night
paper does not break spigot plugin compat
next stratus
Public ๐ฌ
eternal night
next stratus
lmao thanks
eternal night
you basically need to also include the bukkit adventure platform
which basically links bukkit servers to adventure (e.g. allows you to send messages etc)

Is it obvious i'm going crazy yet?
eternal night
Technically legacy format does support rgb colours :>
next stratus
So if I add this adventure will the plugin still be useable on spigot servers or just paper?
eternal night
You will have to shade (or use the library loader) both adventure and the bukkit platform
but yes
next stratus
so i can just shade it?

Is it possible to get the exact coordinates where an arrow hits a player?

if you meant like the arrows cords
I assume you could get the Arrow entity involved and get its coords and just use some math with player information like we know how tall players are
so use the player coords, along with their height, then you can measure where it hit the player

quaint mantle
oof
worldly ingot
Unless you keep track of that yourself
PCE, save the location in memory and in a file or something, load up on start
quaint mantle
how would I do that?
worldly ingot
Well, you can getBlocks() in the PCE. That gets you all the blocks that belong to the portal. (You can just select one if you want, I don't know what location you want, exactly. Calculate the center, whatever). Then just add that location to a Multimap<UUID, Location> or something that you can refer to later
(multimap because they might create more than one portal. If you only care about the most recent, you can just use a regular hash map)
quaint mantle
ok because I was trying to make a type of manhunt plugin so yea that helps a lot thx u :)
worldly ingot
Oh then yeah, if it's temporary, a simple Map will do then
If you need it across restarts as well, you have to write that Map to a file as well. Keep that in mind
If needed, Google has a bunch of resources on how to read/write from files. Standard Java for that

Just add a boolean in the runnable.
Or make the state of the runnable serializable.

so youre able to cancel the tripwire from being being activated while you step on it, but that would create a large loop of it being activated from you stepping on it, then it being deactivated through the blockphysics event over and over, is there a way to prevent this?

guys how to use serializable interface?
The serializable interface just lets you serialize the class
sly trout
I'm trying to serealize this class
private static ArrayList<Report> _allReports = new ArrayList<>();
private int _questionsIndex=0;
private UUID _creatorUUID;
private String _creatorUsername;
private ReportType _reportType = null;
private List<String> _answers;
private String _creationDateToString = "Non-specified";

low temple
All u gotta do is then pass it as an object when writing it to a file
lost matrix
I looked at the docs but it aint that clear
https://www.spigotmc.org/wiki/introduction-to-serialization-section-2/
Did you read this?
sly trout
i used this
file.getConfig().set(data.getPlayer().getUniqueId() + ".PlayerData.ActiveReports", data.getActiveReports());
this should be correct
but the fetching from config part is what i'm stuck at
low temple
Oh youโre trying to serialize in yml format. Nvm
full forge
i'm making a really simple discord-minecraft link using jda, but whenever i call Bukkit.broadcastMessage() with color codes in the string, it sends strange characters like "ร". here's my code: Bukkit.broadcastMessage("ยง9Discord > ยงe" + event.getGuild().getMember(event.getAuthor()).getNickname() + ": ยงf" + event.getMessage().getContentDisplay());. it's not a jda issue because when i remove the color codes everything actually works
low temple
but the fetching from config part is what i'm stuck at
Use #getConfig#get(String path)
So if ur getting by UUID pass the UUID as a string into the path
sly trout
So I have to make the serialize method
that @Override the one from ConfigurationSerializable?
low temple
That depends if you want it to be readable or not
You could probably serialize the object into a byte array then store it into the UUID index. OR create a method to serialize all the primitive values into a string.
low temple
```public class Report implements Serializable, ConfigurationSerializable {
...
because ur using Lists and ArrayLists you should probably just serialize the byte array of the class then save it into the UUID index
low temple
It might, im not sure how they handle those kind of arrays
if it does then you'd serialize those two object however ConfigurationSerializable does
just make sure ur serialize method is consistent with ur deserialize method
like the order and placement of each data value

Every tick the server iterates over every single entity and calls its tick method.
Over every ITickable even.
eternal night
don't think spigot has a way for you to stop stop ticking completely for certain entities
lost matrix

You could just disable their AI.
Disabling the whole tick would mean that they are just displayed statically hanging around.
vale cradle
You could just disable their AI.
Disabling the whole tick would mean that they ...
yes I don't mind that
eternal night
Just as a heads up, disabling AI will not reduce the tick to just a method call
the server will still do stuff and throwing a crap load of entities onto it might still have a noticeable impact

it doesn't matter?
Its only for the OS. The binary data is unchanged
lavish hemlock
Yeah file extensions are kind of an illusion
They exist just to aid programs in detecting the type of a file
But in reality they're just another part of the name
I recommend you do the following:
- Have it end with
.jsonso people aren't (more) confused - Make sure to specify the plugin name so people know where it comes from
- Make sure to specify what its for so people know why it exists
e.g. if you're converting something like a bunch of User objects to a file
you might want something like <my-plugin>-users.json (replacing <my-plugin> with your plugin's name)
Simple shit honestly
hexed hatch
or make a folder and store each user in their own json file like a gigachad
lavish hemlock
You can do that too
Although it makes me wonder whether or not it's faster to read a big file or a bunch of files
I think it depends on how much you'll be reading at a time
hexed hatch
this is spigot minecraft game server
I don't think there is any major difference in efficiency between the two
lavish hemlock
Well file IO does perform native calls
It's gotta open the files
(Plus it's all synchronized since java.io is thread-safe)
lost matrix
It shouldnt really matter if it takes .01 or .1 second because it should be done async anyways.
lavish hemlock
It shouldnt really matter if it takes .01 or .1 second because it should be done...
True
Unless like
It's at the start of the server
Then it's negligible imo
sly trout
I'm kinda lost tho once u got the fileinputStream how do you get the json object or string?
lavish hemlock
Are you looking at fromJson?
You need to use toJson when serializing.
Unless by "json object" you mean Object
In which case you pass your instance in
lavish hemlock
gson.toJson(myData, inputStream);
sly trout
okay but i can't store multiple different json things in a single file?
lavish hemlock
You can store a list
sly trout
so one file means one list?
lavish hemlock
Just one instance in general
e.g. you could store an array, a list, a map, a single object, a primitive (int, float, etc.)
lavish hemlock
`gson.toJson(myData, inputStream);`
Converting from JSON is easy too
Also wait
You need an output stream for toJson lol
sly trout
?
lavish hemlock
So
OutputStream = Writing
InputStream = Reading
toJson = Serializing to JSON
fromJson = Deserializing from JSON
yeah that's my point
you need a FileOutputStream
lavish hemlock
Can you show your actual method call
vale cradle
FileOutputStream is what you're looking at, If you need something to store there just put the bytes of the string the toJson method returned
with the ByteArrayOutputStream I think
lavish hemlock
Nope, notice Appendable?
That's the supertype of Writer
I am terribly sorry for misleading you @sly trout You actually need a FileWriter
My brain isn't working well :p
vale cradle
there it is
lavish hemlock
I'll just give you an example
sly trout
My brain isn't working well :p
no problem you tried to help ๐
lavish hemlock
// This is a try-with-resources statement - It closes the writer after you're done using it to free up resources.
try (FileWriter fw = new FileWriter("myfile.json")) {
gson.toJson(object, fw);
}
Btw if a type implements Closeable
You should always make sure to close it after you're done using it
either via .close() or a try-with-resources
sly trout
okay ๐
lavish hemlock
There's actually some types that will fail to write correctly if not closed (e.g. ZipOutputStream)
sly trout
no need to save?
lavish hemlock
What, with Bukkit's methods?
Those are only for the plugin's YAML configuration.
Writing to a stream or writer means that it outputs the bytes immediately (or at least after a .flush(), although most types auto-flush on close)
So yeah you don't need to save.
sly trout
okay
vale cradle
still, make sure you're writting into the file every time you make a change
vale cradle
and a type
lavish hemlock
try (FileReader fr = new FileReader("myfile.json")) {
Object o = gson.fromJson(fr, Object.class);
}
(I recommend generics here)

Pass the data folder to the function
e.g. myFunction(getDataFolder())
sly trout
wouldn't that work : ArrayList<PlayerData> data = (ArrayList<PlayerData>) _gson.fromJson(fileReader, Object.class);
lavish hemlock
It actually probably wouldn't
Gson needs to know the type so it can find the correct fields
Gson's generic types are...
not easy to work with
dawn hazel
e.g. `myFunction(getDataFolder())`
cant reference the function in another class because it is not static
lavish hemlock
for complicated reasons you can't do List<PlayerData>.class
lavish hemlock
cant reference the function in another class because it is not static
Then make it static
Just make a util function :p

what should i do then
vale cradle
Then make it static
I don't think he can, cuz the function is already defined
lavish hemlock
Btw what version of Gson are you using...?
dawn hazel
Then make it static
the problem is i cant make it static otherwise i get errors

Ah so the one that comes with Minecraft? That's probably older then

no the Google. something

but you can create a static function in other place and then call that function is that what you're looking at?

what should i do then
Type type = TypeToken.getParameterized(List.class, PlayerData.class).getType();
That's how you get the type List<PlayerData> ^
Java is fucking great sometimes no sarcasm intended whatsoever
lavish hemlock
Because Java is complicated when it comes to type parameters
See
To explain why
I have to walk you through what type params really are
They're basically like method parameters but for a type
Meaning you can safely say a List contains Strings
e.g. List is declared like uhh
public interface List<T> implements ...
T is then specified when you create a new List (or ArrayList)
like List<String>

lavish hemlock
List<String> list = new ArrayList<>();
list.add(""); // The compiler knows that we must pass a String to 'add' because it's a List<String>
// Before Java added generics, it looked more like:
List stringList = new ArrayList();
list.add("");
list.add(0); // Oops, we just passed an integer in a situation where we want *strings*
Now
Since Java didn't start with generics
adding them broke some backwards compatibility or smthn
so they had to figure out a way to make it compatible
and because of that
Type parameters don't exist at runtime.
List<String> compiles down to just a raw List
Which is why we can't state List<String>.class bc there's no way for the compiler to make that work
TypeToken is a hack that allows us to keep that type parameter information
I don't really know how it works so I won't explain it.

eternal night
guys i really need to know where (and when) do the MapRender.render(...) trigger
The general updating occurs in the ServerPlayer's doTick method
which sends update packets for every complex item in the players inventory (which rn is just maps xD)
the update packet for maps is only send every 5 ticks or if the map palette is dirty (e.g. a pixel was set)
vivid cave
@eternal night thank you! and what if the map is not in players inv but on an item frame
eternal night
Eehh I think it loads the map from the server based on id ?
and from there on it is just static
at least I don't recall any map item ticking for item frames
chrome beacon
Yeah it should be from id

Not much of an algorithm: You just iterate using two nested for loops

im unsure if bigger values take longer to compare
x1 >> 4; x2 >> 4; z1 >> 4; z2 >> 4;
for(int x == x1, x<x2, x++){
for(int z == z1, z<z2, z++){
Bukkit.getChunkAt(x,z);
Something like this:
public List<Chunk> allChunksBetween(final int x1, final int z1, final int x2, final int z2, final World world) {
final List<Chunk> chunks = new ArrayList<>();
final int minX = Math.min(x1, x2);
final int maxX = Math.max(x1, x2);
final int minZ = Math.min(z1, z2);
final int maxZ = Math.max(z1, z2);
for (int x = minX; x <= maxX; x++) {
for (int z = minZ; z <= maxZ; z++) {
chunks.add(world.getChunkAt(x, z));
}
}
return chunks;
}
iirc he is using coordinates, wouldn't that trigger 256 times per chunk

I thought he meant chunk coordinates

'to find all the chunks that have blocks in that rectangle'
thorny python
but thanks anyway

public List<Chunk> allChunksBetween(final Location a, final Location b) {
Preconditions.checkArgument(a.getWorld().equals(b.getWorld()));
return allChunksBetween(a.getBlockX() >> 4, a.getBlockZ() >> 4, b.getBlockX() >> 4, b.getBlockZ() >> 4, a.getWorld());
}
huh

lol

imma copy that

ya I may over complicate the problem

Maybe. What are you trying to do?
thorny python
but btw should use Set instead of List for the internal use I guess
wait
nvm it should be fine
lost matrix
Maybe. What are you trying to do?
I wanna know ๐
Maybe its a xy problem
thorny python
similar like res plugin
I want to map location to an area object
so I can know which area player currently inside
lost matrix
Oh. Then you should def not touch any chunks. You need to think more abstract for this.
thorny python
to avoid O(n) iteration, I am currently decide to use chunk as bucket
lost matrix
This makes a bit more sense.
thorny python
so map location to chunk first, then iterate over areas in the chunk bucket
lost matrix
Thats also what i did for my regions.
BoundingBoxes with chunks as buckets
thorny python
ya otherwise it could be slow when too many area or region
