Hi! I have some questions about Spigot development, and is wondering if someone could help me out.

So I'm not at all new to coding or Minecraft datapack/resource pack creation, but I've been trying to get into modding the past few months and have been very interested. I've been using MCreator, but have found it very limited and I'm looking for something a bit more advanced. Is Spigot what i'm looking for?

#

if not could someone point me in the right direction

rough drift Mar 4, 2022, 9:53 PM

true shuttle Hi! I have some questions about Spigot development, and is wondering if someone ...

Spigot is for plugins, I'd suggest for mods Fabric

#

its way better than forge

hexed hatch Mar 4, 2022, 9:53 PM

#

Spigot is server-side mod development, they’re called plugins

rough drift Mar 4, 2022, 9:53 PM

#

and they have a friendly comunity

hexed hatch Mar 4, 2022, 9:53 PM

#

You can’t add assets to the game and it only works for servers

true shuttle Mar 4, 2022, 9:54 PM

#

r there any benefits to fabric or spigot?

hexed hatch Mar 4, 2022, 9:54 PM

#

Spigot is strictly server-side

#

They’re not really that comparable

#

Fabric is full-on mod development

rough drift Mar 4, 2022, 9:54 PM

#

true shuttle r there any benefits to fabric or spigot?

fabric is client side and server side, and is made for mods

#

plugins are just extensions of a server

sullen marlin Mar 4, 2022, 9:54 PM

plugins dont need updating every version

rough drift Mar 4, 2022, 9:54 PM

any tips or anything for getting started in Fabric?

its fine if i put fabricord link right?

hexed hatch Mar 4, 2022, 9:56 PM

Having a full understanding of Java is imperative

rough drift Mar 4, 2022, 9:56 PM

#

^

quiet ice Mar 4, 2022, 9:57 PM

#

Fabric is also extra complicated compared to fabric as you may need to have some understanding of java bytecode

#

Though I think you can just skip that requirement

true shuttle Mar 4, 2022, 9:57 PM

#

quiet ice Though I think you can just skip that requirement

skip the java requirement?

hexed hatch Mar 4, 2022, 9:58 PM

#

No

#

Not at all

quiet ice Mar 4, 2022, 9:58 PM

#

The java bytecode knowledge requirement

hexed hatch Mar 4, 2022, 9:58 PM

#

You must have a good understanding of Java concepts before even looking at Fabric modding

#

Otherwise you’re going to be throwing yourself at walls

quiet ice Mar 4, 2022, 9:58 PM

#

Java knowledge is imperative, and java bytecode knowledge is highly recommended otherwise you'll get confused with mixins (which is a hard-requirement for fabric modding)

#

Bukkit is thankfully much more beginner-friendly there

rough drift Mar 4, 2022, 9:59 PM

true shuttle Mar 4, 2022, 9:59 PM

#

ok so imma be honest here, i have experience in coding, but no experience at all with java

#

im prepared to learn tho

hexed hatch Mar 4, 2022, 9:59 PM

#

Start there

quiet ice Mar 4, 2022, 10:00 PM

#

Otherwise you could just start contributing to already existing projects (or just try to learn it).
However honestly said, fabric projects have terrible structure mostly and many fabric tutorials teach things that are mostly against common java conventions

true shuttle Mar 4, 2022, 10:01 PM

#

hexed hatch Start there

wait start where? sorry

hexed hatch Mar 4, 2022, 10:02 PM

#

Learning unadulterated Java

quiet ice Mar 4, 2022, 10:03 PM

#

The the most usefull concepts you should be familiar with before starting with modding is
a) reading & Understanding Compiler errors
b) Reading & Understanding Stacktraces
c) Reading & Understanding Javadocs

hexed hatch Mar 4, 2022, 10:04 PM

#

Geol, if I wanted to familiarize myself more with bytecode and how it works, where would you recommend starting?

quiet ice Mar 4, 2022, 10:04 PM

#

More than half of the issues we solve in #help-development can be answered without consulting us if you were to be familiar with all three steps

quiet ice Mar 4, 2022, 10:07 PM

#

hexed hatch Geol, if I wanted to familiarize myself more with bytecode and how it works, whe...

I learned quite a lot from playing around with Recaf, Decompiling stuff, writing bytecode by hand and also by writing my own mod loader.
But https://cr.openjdk.java.net/~iris/se/17/latestSpec/java-se-17-jvms-fr-diffs.pdf is the most important resource you'll have (especially chapter 6.5)

hexed hatch Mar 4, 2022, 10:08 PM

#

I appreciate the advice, I’ll poke around there. I’d like to think I’m a pretty competent Java developer, but when it compiles it’s black magic to me beyond that point.

true shuttle Mar 4, 2022, 10:10 PM

quiet ice Bukkit is thankfully much more beginner-friendly there

so would might it be best to start with Bukkit? I know there r some things u can't do with it, but would it be a good place to start?

quiet ice Mar 4, 2022, 10:11 PM

#

Bukkit is impressively powerful.

#

Sure, you cannot add new blocks or mobs or anything without going into really complex territory, but you can get accustomed to minecraft basics.
Just note that bukkit is completely different to forge or fabric for example especially in the way it is built. Another alternative would be sponge, but that one is more complicated even though many contributors of bukkit are now working on sponge

cool, this sounds good!

#

i have a few questions tho

#

what's the difference between bukkit and spigot, and is this the wrong server to talk about bukkit?

quiet ice Mar 4, 2022, 10:15 PM

#

nowadays they are the same thing

#

The bigger difference is spigot and paper (latter is a fork of spigot) but for starters they are mostly the same things until you get into the details

true shuttle Mar 4, 2022, 10:16 PM

#

is there a reason to choose one over the other?

#

bukkit v spigot

quiet ice Mar 4, 2022, 10:16 PM

#

Bukkit is dead for half a decade now, there is no choice

true shuttle Mar 4, 2022, 10:17 PM

#

oh ok

sterile token Mar 4, 2022, 10:17 PM

#

bUKKIT ITS dead

#

Now you should fork Spigot or Paper

quiet ice Mar 4, 2022, 10:17 PM

#

If you touch on a site claiming to distribute bukkit you are most likely on the wrong size

#

You shouldn't fork spigot either

true shuttle Mar 4, 2022, 10:18 PM

#

wait so spigot or paper?

quiet ice Mar 4, 2022, 10:18 PM

#

Yeah, though of course here we support spigot

#

?bt is the only legitimate way of obtaining it

https://www.spigotmc.org/wiki/buildtools/

true shuttle Mar 4, 2022, 10:21 PM

#

ok so i dont wanna offend u guys, but imma start with paper. After reading a bit about it, it seems to be slightly better and have a larger community, so imma start there

#

unless theres something im missing

quiet ice Mar 4, 2022, 10:22 PM

#

A few people find paper's community less welcoming but honestly as long as you are on online mode and on the latest version you are pretty much welcome anywhere while if you are not on either you aren't welcome anywhere (though here many are far more accepting towards 1.8 in particular)

eternal oxide Mar 4, 2022, 10:23 PM

#

Things written for Paper stand a good chance of not running on Spigot. Write for Spigot and it works on both.

quiet ice Mar 4, 2022, 10:23 PM

#

In the end, it's a personal choice, just like choosing a linux distro
Also yeah, Elgar's advice stands true plus you cannot distribute paper-only plugins on spigotmc

Hey, I have a question that is probably from the java basics but if I had some checks with or (two of |) and then had an else does the else also work if one of the checks is true so doesn't have to be both true?
Example:

if(isPlayerFlying() || isPlayerCrying()) {
  //Do something
} else { //If one of the checks above is true and the other is false will this run?
  //Do something
}```

tall dragon Mar 4, 2022, 10:30 PM

#

no

#

the else statement will not run

rapid vigil Mar 4, 2022, 10:30 PM

#

Will it only run if both are true?

tall dragon Mar 4, 2022, 10:30 PM

#

if both are false

#

the else will run

rapid vigil Mar 4, 2022, 10:30 PM

#

I meant false**

tall dragon Mar 4, 2022, 10:30 PM

well yes then

isnt lightning a particle effect as far is client is concerned?

i was just trying to do it with EntityInteractEvent and that wasn't workign

#

tyvm

smoky oak Mar 4, 2022, 11:07 PM

wait

#

there's a good chance parsing '{}' to json results in an empty string

#

since it does not contain any values

waxen plinth Mar 4, 2022, 11:07 PM

That would be empty map not empty string

or rather

#

the full stack trace

#

thts probably a lot easier to deal with

how the fuck do you have a stack trace not saying 'caused by'

surround with try/catch do e.printStackTrace()

#

Yes i dont know too

smoky oak Mar 4, 2022, 11:14 PM

well maybe it's because you're using that class in particular

#

but seriously getting an error without an caused by is a once in a blue moon thing in java

sterile token Mar 4, 2022, 11:14 PM

#

Just say me that something its null on line 44:

smoky oak Mar 4, 2022, 11:15 PM

#

actually it says 'caused by null on line 44 which results in an error on line 13' if i read that right

sterile token Mar 4, 2022, 11:15 PM

#

Could be caused because im doing?

FileHandler json = new JsonFile()

#

Instead of doing JsonFile file = new JsonFile?

smoky oak Mar 4, 2022, 11:15 PM

#

maybe

#

i dont know for sure

#

but it could be that the @Override doesnt get loaded

sterile token Mar 4, 2022, 11:16 PM

No it isnt, its the same

smoky oak Mar 4, 2022, 11:16 PM

this is uncharted waters for me tho

sterile token Mar 4, 2022, 11:16 PM

Im like okay hat happening them

#

But dont worry i just want to know how i can add "{}" inside the file?

#

if (this.file.length() == 0) new BufferedWriter(new FileWriter(this.file)).write(this.gson.toJson("{}"));

Cuz doesnt work

smoky oak Mar 4, 2022, 11:17 PM

#

lemme check smth

sterile token Mar 4, 2022, 11:17 PM

#

Allright

#

Im using Gson

smoky oak Mar 4, 2022, 11:18 PM

#

ah

#

welllllll

#

considering this is what the docs say

#

i dont think you can just write "{}" to a file

#

im not 100% sure but i think toJson("{}") just returns an empty json tree

#

as such

#

it writes nothign to the file

#

just creates it

tall dragon Mar 4, 2022, 11:19 PM

#

why not write {} without converting to json

smoky oak Mar 4, 2022, 11:19 PM

#

(if im right)

#

well

#

thats a solution too

#

ima go sleep now

#

gl

sterile token Mar 4, 2022, 11:20 PM

#

Hmn, because if i write manually "{}" inside the json file. And then try to set values it doesnt throw error

#

So i dont understand

tall dragon Mar 4, 2022, 11:20 PM

#

i usually have a file in my jar that i just copy to the directory

#

with {} in it

sterile token Mar 4, 2022, 11:20 PM

Oh how?

#

Can i see yours?

#

That what you mean Epic?

tall dragon Mar 4, 2022, 11:20 PM

#

yea

sterile token Mar 4, 2022, 11:21 PM

#

I will try

tall dragon Mar 4, 2022, 11:21 PM

#

and when json converts it back it should just be an empty json element

sterile token Mar 4, 2022, 11:21 PM

#

Nop, still getting the error

#

Idk why, but it doesnt write to the file

tall dragon Mar 4, 2022, 11:21 PM

#

uhh

#

let me see if i can find some json work i made

sterile token Mar 4, 2022, 11:22 PM

#

Yeah im feeling like you right now

#

Because everything works except that yeath

tall dragon Mar 4, 2022, 11:23 PM

#

this is what i do to save json

#

@Override
    public void save(IslandCache cache) {
        try {
            StackerPlugin.sendDebug("Island Cache " + cache.getUUID() + " has been unloaded and saved.");
            createFileIfNotExists(storage.resolve(cache.getUUID() + ".json"));
            Files.write(storage.resolve(cache.getUUID() + ".json"), GlobalGson.GSON.toJson(cache).getBytes(StandardCharsets.UTF_8));
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

#

for example

sterile token Mar 4, 2022, 11:23 PM

#

I have Files.class marked as @Beta

#

That why i dont use it

tall dragon Mar 4, 2022, 11:23 PM

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Absolutely not

You are in a situation where you have a lot of objects of different names

yeah thats right

lost matrix Mar 5, 2022, 11:18 AM

Then you should not used PDCs nor ItemStacks.
Something like

Map<UUID, Map<SpellType, Long>>

Would be the cleaner approach.
And even wrap the Map<SpellType, Long> in a serializable SpellCooldownDomain or SpellCooldownContainer

SpellType would be my own class right

lost matrix Mar 5, 2022, 11:19 AM

Yes it would be an enum. Ive chosen an enum because its easily serializable.

#

You could also make this a bit more dynamic if you wanted. But then serialization gets really complicated.

#

i would guess something like this

lost matrix Mar 5, 2022, 11:22 AM

#

You add a pdc to the ItemStack.
Key: Spells
Value: SpellType[]

Then in the interact event you check if the ItemStack has this key and then you get all
values and let the player cast it.

Take one step at a time. Try to quantify your problem.
First: How do i "map" an ItemStack to a SpellType
So define 2 methods:

    public List<SpellType> getSpells(ItemStack itemStack) {
        
    }

    public void addSpell(ItemStack itemStack, SpellType spellType) {

    }

And think of them like a closed system. (Meaning those methods are not concerned about anything else but their single task)

quaint mantle Mar 5, 2022, 11:32 AM

#

I think what 7smile said about the stdout data might work I will learn about it

lost matrix Mar 5, 2022, 11:36 AM

#

lost matrix Take one step at a time. Try to quantify your problem. First: How do i "map" an ...

If you still have problems defining the problem then try to first define the responsibility of this method with a doc comment:

    /**
     * This method returns all SpellTypes on this ItemStack.
     * If there are no SpellTypes present then an immutable
     * empty List is returned.
     * @param itemStack the input ItemStack
     * @return A List of SpellTypes
     */
    public List<SpellType> getSpells(ItemStack itemStack) {

    }

Now we just need to think on how to implement this properly

#

Hint: A PDC entry can contain several Strings and therefore several Enums

quaint mantle Mar 5, 2022, 11:38 AM

#

How does logging data work?

lost matrix Mar 5, 2022, 11:39 AM

#

    PrintStream yourCustomPrintStream = ...;
    System.setOut(yourCustomPrintStream);

This would be one approach. Its not a logger but replaces stdout.

#

Probably a good idea to just wrap the original stdout and delegate its data.

There is no way to use it as a small scripting language, although java MyClass.java exists and we have jshell as of 9.
...although it's also still a shithead to run since classpath + version management (praise our lord SDKMAN!).
(Also you have to declare a full class)
I know this isn't what it was meant for, but Java has a strong ecosystem that would be great with some proper scripting support.

My other reason is personal opinion: Too much ceremony.

lavish hemlock Mar 5, 2022, 12:42 PM

#

Actually you make a good point

#

I never thought about Optional -> Option compat (and vice-versa)

lost matrix Mar 5, 2022, 12:43 PM

#

Maybe some conversion functions to easily pipe one into the other would be a good idea

lavish hemlock Mar 5, 2022, 12:43 PM

#

Yeah that was the idea

#

e.g. uh

#

Option.from(Optional) and Option.toJava() // Optional/toOptional()

#

uh can i throw in two questions of my own, before you guys keep talking the next hour about code design?

lavish hemlock Mar 5, 2022, 12:43 PM

#

Yeah

smoky oak Mar 5, 2022, 12:44 PM

#

so 1) to write a library, do i need to do more than define public functions and import said library into a project?

lavish hemlock Mar 5, 2022, 12:46 PM

#

I

#

suppose so?

#

I mean libraries aren't just public functions

#

Unless they're like a collection of interfaces

#

like uhh service providers, adapters (like Bukkit), etc.

#

Usually under the public stuff, you have some private implementation, which is where encapsulation comes in handy.

#

I mean my full username is an encapsulation joke

#

See uhh on GitHub my profile says

#

oh wait nvm

#

but anyway so MaowImpl but I usually go by Maow

#

Shit Java joke, yes

Anyway so yeah libraries can be kinda complicated

smoky oak Mar 5, 2022, 12:48 PM

#

i think i know what you mean tho

lavish hemlock Mar 5, 2022, 12:48 PM

#

At most you need basically

#

An entrypoint

#

That can be like, an abstract class, or maybe a final, uninstantiable class containing static methods.

smoky oak Mar 5, 2022, 12:50 PM

#

does setting a class final make it unable to be extended/implemented?

lavish hemlock Mar 5, 2022, 12:50 PM

#

Yeah

#

Uninheritable is the word you're looking for

#

Although you can't make a final interface

smoky oak Mar 5, 2022, 12:50 PM

#

considering interfaces are meant to be inherited

is there any simple code to send an action bar to player? like
player.sendActionBar(...args...)

smoky oak Mar 5, 2022, 12:51 PM

#

I suppose that makes sense

lavish hemlock Mar 5, 2022, 12:51 PM

#

I have this common pattern in my project for util classes:

public final class FuckUtils {
    private FuckUtils() {
        throw new UnsupportedOperationException():
    }

    public static void util() { ... }
}

You don't need to do this, I'm just a perfectionist.

smoky oak Mar 5, 2022, 12:51 PM

#

huh manually throwing an exception might be useful tho

tardy delta Mar 5, 2022, 12:52 PM

#

wait why throwing an exception in a private constructor

lavish hemlock Mar 5, 2022, 12:52 PM

#

tardy delta wait why throwing an exception in a private constructor

Stops reflective instantiation.

smoky oak Mar 5, 2022, 12:52 PM

#

cant be created

tardy delta Mar 5, 2022, 12:52 PM

#

grr reflection

lavish hemlock Mar 5, 2022, 12:52 PM

#

It literally cannot be created unless you use Unsafe

#

But at that point I give up lol

smoky oak Mar 5, 2022, 12:52 PM

#

eh fair

#

my second question is a bit more complicated tho

#

is there a simple way to check if a structure (resources/structure.nbt) is present in the world at specific coordinates?

#

if yes how

lavish hemlock Mar 5, 2022, 12:53 PM

#

Probably not

#

Well

last tulip Mar 5, 2022, 12:53 PM

tardy delta ``player.spigot().sendMessage(MessageType.ACTION_BAR, textComponent)`` or smth

i found
player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent("text"));

but error says
'TextComponent(java.lang.String)' is not public in 'java.awt.TextComponent'. Cannot be accessed from outside package

lavish hemlock Mar 5, 2022, 12:53 PM

#

Structures? Hmm

smoky oak Mar 5, 2022, 12:53 PM

#

well

lavish hemlock Mar 5, 2022, 12:53 PM

#

Definitely not schematics

smoky oak Mar 5, 2022, 12:53 PM

#

either would be fine

lavish hemlock Mar 5, 2022, 12:53 PM

#

You'd have to ask someone else I know fuck all about structures
