usually i’d

[tidal lance]

ah

[storm aspen]

if you are using

[tidal lance]

i think i checked those but couldn’t figure out which exactly registered the items

[storm aspen]

net.pickhaxe.compat.world.item.Item

[tidal lance]

cus im used to Registery.register

[storm aspen]

For reference

net.pickhaxe.compat.world.item.Item is a wrapper

around the vanilla Minecraft item class

in fact it replaces it at compile time so you can use it in all the same places

the things it does include:

actually currently the only thing it does is add Item.register()

which calls either Registry.register for Fabric or whatever convoluted stuff I did to make it work on Forge

[tidal lance]

ah

[storm aspen]

More work is getting done

1.16.2-1.20.2 as well as the latest snapshot all tested and working on Fabric

Forge is giving me grief as usual

[tidal lance]

ooooo

[tidal lance]

oof, sorry to hear

[storm aspen]

50% their fault 50% mine really

They did things in a weird way and I did weird things to them

[storm aspen]

For reference, the current existing blocking issues are:

• Fabric, 1.16.2 and earlier: NoSuchFieldError: displayName when initializing a CreativeModeTab. Very low priority since most people use 1.16.5.

• Forge, 1.19.2 and earlier: NoSuchFieldError: f_40748_ when initializing a mod with a CreativeModeTab. This drives me insane because f_40748_ (which translates to CreativeModeTab.TABS) DEFINITELY exists.

• Forge, 1.19.3 and later: Installing multiple mods utilizing PickHaxe at the same time throws an error that two classes with overlapping classpaths exist.

The latter issue necessitates the development of a library to rename packages at compile time, which will be its own standalone Haxelib found here: https://github.com/EliteMasterEric/haxe-shade

During the development of haxe-shade, I encountered a compiler issue which has halted its development, which has been reported to the Haxe Foundation: https://github.com/HaxeFoundation/haxe/issues/11361

Aside from the overlapping classes issue, Forge 1.19.4 works great.

[tidal lance]

oooo epic!

[storm aspen]

I thought from the beginning that PickHaxe would be a simple project but I hit the boundaries for what kind of output Haxe->JVM was capable of pretty quickly.

The good news is that everything that gets changed for this project helps everyone, really.

I got Forge 1.19.4-1.19.0 working, Forge 1.18.2 doesn't work because of a Haxe bug, multiple Forge mods at once doesn't work because of a Forge bug, Forge 1.17 has some Gradle issue I need to work, Fabric is working on everything up until 1.16.1 but who cares about that

and Forge 1.20 also had some Gradle issue that I can probably figure out just fine

[storm aspen]

This screenshot summarizes my project nicely

[dusty prism]

how does it feel to be the only user of the jvm target

[storm aspen]

bittersweet

[storm aspen]

Another issue just got merged and I have a new working sample project. This one doesn't use any custom library code provided by PickHaxe, but only builds for a specific version of Minecraft.

You still use pickhaxe build to create a jar, but this is to demonstrate that net.pickhaxe.core.CommonMod is optional. You can simply invoke Fabric's methods and classes and it will work 100%. Using this, you can make full use of Haxe's language features when developing Minecraft mods.

Check it out: https://github.com/EliteMasterEric/PickHaxe-Samples/tree/master/madeinhaxe-bare

I'm going to continue work on more cleanup, including:

• Tested working builds for the main samples on all supported versions.
• A few new features for the build tools.
• More versions for the madeinhaxe-bare sample project

before releasing 0.4.0 publicly

[tidal lance]

:o

[storm aspen]

sneak preview

[storm aspen]

Partially working...

there we go! template downloader is working

[storm aspen]

Found a snag with the template downloader, but I made a way to specify a GitHub API key if you have trouble

[dusty prism]

How are you downloading templates? I know you don't need a API token to access releases, regardless of what their documentation says

[storm aspen]

I have a JSON file which contains the relative paths of each sample along with a name and short description

When I choose a path for a sample I fetch a directory listing via API and iterate over it recursively

I do this since I want to download whatever is in the repo (so I don't have to make a release) but I don't want to download the whole thing

https://docs.github.com/en/rest/repos/contents?apiVersion=2022-11-28#get-repository-content

[storm aspen]

[showcase] PickHaxe, the Minecraft modding framework for Haxe, has been making a lot of progress in its tooling lately. Here's a demonstration that goes from an empty workspace to a sample mod working in-game in less than 2 minutes (most of that is build time ehe).

[tidal lance]

oooh sickkk!

[storm aspen]

Next upcoming stable release is SOON-ISH! working on polishing stuff

[tidal lance]

can’t wait :3

[storm aspen]

[showcase] PickHaxe v0.4.0 is live on HaxeLib. This version was a long time in the making, in part due to issues with the Haxe compiler itself; now, most of those are resolved. Fabric 1.16.5-1.20.2 (+ snapshots!) as well as Forge 1.18.2-1.20.2 are now fully supported and have working sample projects, and the built-in tools for developing for both have greatly improved. If you have any problems, please make an issue or post in #1085695464466296932 .

[storm aspen]

...and 0.4.0 is broken. fun.

[storm aspen]

...v0.4.1 is live!

[tidal lance]

oooo

[storm aspen]

Docs got an update too so they should be a good place to start

[tidal lance]

thats strange

i built the madeinhaxe template but the custom item isnt there?

[storm aspen]

which version

[tidal lance]

1.20.2

fabric launcher

[storm aspen]

trying a new build from scratch to see

The commands I'm running are

pickhaxe template madeinhaxe
pickhaxe build fabric 1.20.2 --make

[storm aspen]

the mod isn't being loaded

[tidal lance]

yeah thats what i did

yeah

[tidal lance]

(well, i did build then make, not build --make but theres not much difference between doing either one)

[storm aspen]

any mention of pickhaxe or madeinhaxe in the logs? 🤔

[storm aspen]

(There shouldn't be any difference, build --make just calls the Make function after the build is done)

[tidal lance]

when doing runClient these are the only mentions of madeinhaxe

[storm aspen]

is runClient the only thing you've tried

[tidal lance]

i did build than i did make before doing runclient

i'll try a clean then i'll redo runclient (after building again)

[storm aspen]

ok so:

1. runClient performs a build by default
2. runClient uses the -dev JAR so --make isn't necessary
3. runClient is... iffy at times.

[tidal lance]

oh

[storm aspen]

i just tested and adding the mod to a normal Minecraft instance works

[tidal lance]

alr

[storm aspen]

OH

uh

i forgot to make runClient work on Fabric

i made a note to myself and then forgot to fix it

[tidal lance]

OH

well that woudl explain it

lmao

[storm aspen]

it should work on forge though

[tidal lance]

alr

[storm aspen]

updating github issues now with all the known stuff

yeah runClient works fine on Forge

[storm aspen]

Been hard at work on trying to dogfood PickHaxe and adding a bunch of features in the process

[coarse galleon]

Treat it like family

Or treat it like the black sheep of the herd

[storm aspen]

Coming in 0.5 is support for dependencies

You can add mods as runtime dependencies to your mod metadata or as build dependencies for Haxe

[tidal lance]

oooo nice!

[storm aspen]

Been working on mixins too those should come in 0.5 as well

[storm aspen]

Okay sooo... https://github.com/HaxeFoundation/haxe/issues/11370

Mixins don't work until this is fixed.

[tidal lance]

oof

hope it gets fixed soon

[storm aspen]

Got a bunch of work done this weekend on stuff for 0.5, things you can see in develop right now:

• Mod dependencies
• Mod build dependencies
• Basic implementation of net.pickhaxe.compat for Blocks
• pickhaxe runClient working on Minecraft Fabric

And stuff that is currently broken (dependant on some bug in HaxeFoundation/Haxe):

• Mod data generators
• Mixin support
• Bugfix for PickHaxe Forge mods conflicting with each toher

[tidal lance]

ooooh datagen? sounds awesome, cant wait!!

[storm aspen]

For context, I am making my own mod to ensure the feature set of PickHaxe, and in developing it I need to use the Fabric/Forge datagen APIs.

Implementing DataGen in a mod will involve adding a <mod-data-generator> pointing to a class extending net.pickhaxe.datagen.DataGenerator, and that will provide a single API which calls Forge or Fabric conditionally.

When you're ready to regen data, just call pickhaxe dataGen <loader> <mcVersion>

[tidal lance]

forge has datagen?

or are you just making it so your datagen works with forge too

[storm aspen]

https://docs.minecraftforge.net/en/1.20.x/datagen/

[tidal lance]

oh cool

[storm aspen]

in fact, to be clear

Minecraft VANILLA has datagen

and Forge/Fabric's APIs are wrappers to access it

(PickHaxe is a cool project because I have to learn at a deep level how Minecraft does things)

[tidal lance]

waitwha

damnn

im guessing its for like

the devs to easily make stuff

[storm aspen]

yeah basically the same reason fabric and forge devs use it

creating lots of valid JSON files properly is really annoying

[tidal lance]

true

i can agree after having to create 5 different blockstates for every tree type

well ok maybe 4 i think

[storm aspen]

the mod I'm making is adding trees 🙂 so i can relate

[bright egret]

make a pickhaxe tutorial

and make a minecraft client lib 😈

[bright egret]

forget this

[atomic raven]

https://wiki.vg/Data_Generators

[tidal lance]

no i know what datagen is

[glossy brook]

I have problem when running "haxelib run pickhaxe setup"
[EXCEPTION 301] An error occurred within PickHaxe while performing this operation.
Haxe version mismatch, expected 5.0.0-alpha+, got 4.3.3.

[coarse galleon]

I don't think Haxe 5 exists yet? So this is an interesting error

[tired tundra]

You have to use the latest nightly version. Click on "nightly builds" on top right.
https://haxe.org/download/

[glossy brook]

ok thanks

[glossy brook]

I created the obsidianarmor project. The mod does not appear in the game...

[tidal lance]

if your doing runClient with fabric its a known bug that it doesnt work

[storm aspen]

Yeah, runClient with Fabric only works on develop builds. If you do pickhaxe build fabric 1.20.2 --make that will give you a JAR that works

[onyx remnant]

So how will PickHaxe handling Networking? Will you be creating wrapper classes for each network class of both APIs and then have an overall network class that can support both forge or fabric, or are you going to create your own network classes that use the core minecraft network classes?

[onyx remnant]

Also does this has MacOS support?

[tidal lance]

idk but i dont think it'd be that hard to test

[onyx remnant]

Turns out no, but I'm pushing a commit to change to yes

[storm aspen]

The CLI tool doesn't work on Linux I think there're a couple commands that were written specifically for the fact that Windows hates the paths generated by Gradle

It OUGHT to work on Mac and Linux

But last I tried to use Haxe 5.0 on Linux it gave some weird macro error that didn't show up on Windows so IDK what's going on there.

[onyx remnant]

So far with MacOS, Haxe 5.0 is working fine, I haven't encountered any macro errors (At the moment)

It might be only on Linux, but that's just an assumption

So I made the setup method for MacOS, should I implement an output log warning telling the user that that "It's currently not fully stable on MacOS?"

Until I encounter more potential issues with the CLI tools?

[onyx remnant]

Holy crap, I love laid out everything is! It feels just as easy as settting up a Lime or OpenFL workbench, great job!

[storm aspen]

Thank you, that means a lot to hear

Not sure how much modding experience you have but the compatibility stuff is still being fleshed out. In the meantime, working with Fabric or Forge directly works great, read the docs on the Wiki for more info on that

Note that Haxe's JVM target is basically a full reimplementation of the Java compiler so it may have discrepencies with the output of an actual Java build. Currently, there are some issues with Java annotations and with functional interfaces (i.e. passing a function as an argument to Java)

Did you try to build PickHaxe with Forge 1.16.5? I haven't tested with that version I don't think I noted that anywhere

[bright egret]

any forge 1.16 tested version?

i didn't test with any forge 1.16.0-1.16.5

[onyx remnant]

So how exactly are plugins suppose to work in PickHaxe?

I was thinking of making one but I don't really know if there's anything unique I have to do

[atomic raven]

well considering that neither of the supported platforms are plugin platforms, id say they arent supposed to work

although you probably can do server-side mods, youd probably have to pick forge or fabric (not both) and probably would need to avoid the pickhaxe api

[storm aspen]

PickHaxe does not support Spigot/Bukkit/Sponge server plugins

[storm aspen]

And doesn't intend to LOL, that would expand the scope too much.

[bright egret]

making a spigot plugin server in haxe

make a haxe project in java

make your main class in a directory like: org.tutorial

download this libs:

the .hxml

--java-lib libs/javax.servlet-api.jar
--java-lib libs/spigot-1.8.8-R0.1-SNAPSHOT-latest.jar
--java-lib libs/joda-time-2.12.5.jar
--java-lib libs/javax-crypto.jar
-r plugin.yml
--java bin/java
--main org.tutorial.YourPluginName

plugin.yml:

main: org.tutorial.YourPluginName
name: YourPluginName
version: 1.0
description: Your Description

the main class template:

package org.tutorial;
import org.bukkit.plugin.java.JavaPlugin;

class YourPluginName extends JavaPlugin{
    static function main(){}

    override overload function onEnable() {
        super.onEnable();
    }

    override overload function onDisable() {
        super.onDisable();
    }
}

thats all

now create your own plugin in haxe

[storm aspen]

The fact that plugins don't need to be obfuscated makes developing for it a lot easier. You probably don't need a Haxe framework for it, just the jar files.

[bright egret]

idk

but without that files the project dont export

in a java enviroment you just need spigot.ja

[storm aspen]

I know Haxe does tend to creep up the chain of libraries when resolving types

that's why I have Gradle export all the dependencies for Minecraft.jar and I just include them all

[bright egret]

cool

[onyx remnant]

That makes a lot more sense why I got "missing dependencies" when testing out geckoLib with PickHaxe

[storm aspen]

If you have any gradle dependencies the develop branch has support for those

[tidal lance]

is this project being worked on still?

[storm aspen]

It's currently at the point where all the things I want to work on have blockers tied to Haxe

[tidal lance]

ah

[storm aspen]

(I've also been really into modding Lethal Company lol)

[tidal lance]

oh thats nice

lethal company was made with godot wasnt it?

wait no where did i get that from

nvm

[storm aspen]

unity modding has a pretty solid set of tooling at this point

[dusty prism]

Unlike Unity development...

[storm aspen]

By the way here are the three issues that are hindering PickHaxe development right now:

• https://github.com/HaxeFoundation/haxe/issues/11361
• https://github.com/HaxeFoundation/haxe/issues/10516
• https://github.com/HaxeFoundation/haxe/issues/11390

[storm aspen]

Status update:

• #11361 requires a bunch of rewrites to the JVM target in order to support a -D jvm.root=<package> argument, so it will probably take a while to develop. This is a blocker in fixing a bug where two Forge mods cannot be used together.
• #10516 requires a bunch of requires to @:strict in order to support including annotations as an argument to other annotations. This is a blocker in fixing a bug where Mixins are not properly recognized.
• #11390 is one I just built a minimal reproduction on so we should see progress on it soon. This is a blocker in fixing a bug where DataGen functions will fail at runtime.

I also just today fixed a platform issue with a recent push to develop and builds seem to work on Linux now, wahoo!

[storm aspen]

#11390 got a couple helpful commits yesterday to where I got basic datagen working

so you can run pickhaxe datagen fabric 1.20.2 and utilize the utilities provided by Minecraft to create JSON data

and notably PickHaxe will put those generated JSON files in a directory where they will get used when you perform pickhaxe build

i only learned about datagen recently but it's pretty interesting

• https://docs.minecraftforge.net/en/1.20.x/datagen/
• https://fabricmc.net/wiki/tutorial:datagen_setup

A good example is that you could create a function which

iterates through a list of items and creates an achievement that triggers when you craft each of them

and then when you run pickhaxe datagen Minecraft will convert that into the resource pack JSON that will get included with your mod

Stuff like recipes, loot tables, translation entries, tags, block models, and worldgen features are all powered by JSON and you can write that JSON as code instead using this method

[storm aspen]

I started working on datagen in part for the mod I'm developing which requires the use of worldgen datagen

[tidal lance]

:o thats so epic!!

[storm aspen]

Was able to delete a bunch of resource files and replace them with one datagen class that auto-creates them

[tidal lance]

thats epic

[storm aspen]

https://github.com/HaxeFoundation/haxe/pull/11551

Note this DOESN'T affect PickHaxe since we use the JVM target which is different!

But still sad

[tidal lance]

dawe

sad

[onyx remnant]

Wait does this really mean what I think it means...

Is Haxe no longer going to transpile into Java and C#.....

[storm aspen]

It no longer transpiles to C# and it no longer transpiles to Java SOURCE

They more recently added a feature to transpile to Java BYTECODE and that is staying

[onyx remnant]

holy shit

[storm aspen]

well Haxe 4.x will still support it

but 5.x won't

[onyx remnant]

I assume that's the JVM tranpile

Wait but @storm aspen why C# as well?

[storm aspen]

It explains it in the post

[onyx remnant]

Oh ok, I reread the entire thing and I'm still in shock since I've always promoted Haxe with .NET since I have friends that program in C#

Also will Haxe have parsing for Java still?

[storm aspen]

Like being able to use JARs for externs? yes

[onyx remnant]

oh but not with source .java files

atleast that's not a total lost, however, it seems that Haxe is competing with Kotlin and Scala

[storm aspen]

PickHaxe is one of the more elaborate projects to use the JVM target I think

partly because Minecraft modding requires the output be very precise in a way that doesn't matter much when using javac as your compiler

but with the custom bytecode generation one mistyped annotation will just cause a mixin to become unreadable

[onyx remnant]

Ah, I don't know much about mixins except for the brief explanation you gave during a Haxe round up, but that sounds actually terrible to debug

I assume next up is native C++ due to HashLink being superior

[storm aspen]

um no

hashlink is still a VM

[onyx remnant]

that's true

I forgot about that

[storm aspen]

so the performance is way better

plus CFFI is really important

[onyx remnant]

I realized that as all my projects rely on the CFFI

but anyways tho, this is really sadding to see Java and C# go

[onyx remnant]

sorry about that I wasn't thinking properly 😅

[storm aspen]

HashLink has its place but personally I haven't been able to use it much

since my main projects either rely heavily on C++ externs or really heavily on Java being the target

[onyx remnant]

If you don't mind me asking, what is HashLink for exactly? I've only used native C++

[storm aspen]

Since HashLink is a VM, the built binary can be run on any target which has HashLink on it.

The main reason to use it is that build times are way faster reportedly

and therefore iteration is faster.

[onyx remnant]

ohhhh ok, that makes sense, thank you

I had a false assumption that it was a VM alternative for C++ in general

[atomic raven]

compiling a flixel game to native can take over 10 minutes on the first compile and ~30 seconds on subsequent compiles (based on hardware ofc), but compiling to hashlink takes like 10 seconds at most every single time

[onyx remnant]

holy crap

[dusty prism]

Get them to contribute to reflaxe.csharp

[onyx remnant]

I gotta get them

[storm aspen]

Latest Minecraft snapshot updated the game to Java 21

This will probably make it harder to update especially if they actually use any of the new language features

[tidal lance]

oh???

damnnn

[storm aspen]

It also means no 32-bit computers for 1.21!

[atomic raven]

or 1.20.5

[tidal lance]

smh finally, no POOR people in my 1.21 servers (/joke)

[onyx remnant]

Is PickHaxe still being worked on? (I love this MC API too much)

[storm aspen]

Haven't really touched it in a while there was a bit of refactoring I wanted to do to move the compat stuff to a separate library

To make it easier to exclude since things work pretty well when you use compile defines to divide up loader specific and version specific stuff yourself

[storm aspen]

[showcase] I spent sometime last night updating PickHaxe to work with Minecraft 1.21, and tested it out by implementing Armor Trim support for the Obsidian Armor sample project.

As part of the refactor, I moved the net.pickhaxe.compat package to its own repository, and reworked the MadeInHaxe sample project to not use it anymore. It is now split up into individual repos for different loaders and game versions.

This should make it easier to maintain. The Obsidian Armor repo will use the pickhaxe-compat library and thus try to maintain cross-platform, cross-loader support.

[tidal lance]

@storm aspen is pickhaxe planned to have support for exporting to neoforge? bcus iirc neoforge has/is removing support for forge mods(i think? take what im saying with a heavy grain of salt)

oh wow that was quick

[storm aspen]

I plan on supporting NeoForge and quilt

But support for even original Forge is kinda lacking right now

[tidal lance]

ah i see

[storm aspen]

I believe the build tools are pretty similar so the plan is to port it over once I get it working

[atomic raven]

i assume you can access the platform api and internals directly just like any mod made directly in a jvm supported language

[storm aspen]

You can call any functions in the Java libraries directly (as long as they're public and even then you can use an access transformer)

The main limitations I'd say are Haxe's slow auto complete with how many java externs it needs to build, along with technical stuff like Mixins not working properly and annoying problems when interacting between Haxe and Java (this method wants a Java array, and that method wants a factory function)

There's also the cross compatibility part of it, I can do something the Fabric way or the Forge way, but to make a single endpoint to work with on PickHaxe I have to reconcile the two. I've made that part of the project into a side library recently for this reason

Fun fact, You don't even need to touch Haxe OR Java to give a block a 3D model, it's perfectly doable with just a resource pack (most mods have at least a small resource pack baked into them to load the custom textures etc)

[errant swallow]

Hey! I've recently tried to make something similar to PickHaxe, but instead as a gradle plugin rather than with a custom build system. One question: The Haxe JVM target will place a haxe package in the output jar, which is almost but not entirely static. Importantly, this package contains generated classes that share names among different mods while having different content. Does PickHaxe have some way of renaming this package, because otherwise it will almost definetely result in conflicts once multiple PickHaxe mods are loaded into the same classpath.

[errant swallow]

Also, how hard would it be to port PickHaxe to MC 1.7.10 (forge)?

[storm aspen]

Okay, so, there IS a way to set the destination path of a class in Haxe

and I have a library that does it: https://github.com/EliteMasterEric/haxe-shade

and that library is used by PickHaxe if you use --shading

however that has a fatal flaw

attempting to remap some of the core Haxe classes (like Array) causes the compiler to break (see this issue: https://github.com/HaxeFoundation/haxe/issues/11361)

The only solution is to wait for the haxe dev team to solve it

So in the current state of PickHaxe, you can only install one Forge mod made in PickHaxe at a time.

Side note, for whatever reason Fabric does not care about multiple mods containing identical classes and package names! Only Forge has issues.

[storm aspen]

as for this it's a matter of setting up the build flags properly and then modifying any externs so they're correct for that version using compile flags

[atomic raven]

ik paper does some classpath isolation magic that causes plugins to throw NoClassDefFound or whatever it is if they dont explicitly depend on another plugin but try to access it, could try to look at what they do and see if its possible to use that in a forge mod

[eager current]

what the fuck do I do here 😭

(this is when I'm trying to run the setup btw

[devout dome]

wrong account lol

oopsies

oh mr.@storm aspen!!!!!
