fabric-example-mod VS Starlight

For accessing a decompiled minecraft source, I think the easiest way is to grab something people use to write mods (like the fabric example mod or the quilt template mod or the forge getting started guide), open it in an IDE like eclipse or intellij, then just don't write a mod and click around in the source instead. Keep the copyrights in mind

If you're making a fabric mod, then you can just use the Fabric Example Mod as template

This is the template I used, and this is what I used to setup the enviroment, I already coded an item into the mod and it all works, but when I go onto the debug tab on the left and run the code, it opens a new game rather than giving me a share-able .jar file I can drag in myself.

You need to go back to the example mod page, and start again from the 1.18 template. There's a dropdown in the top left to switch between versions. If you can't find it, here's a direct link.

Get an IDE you like (I recommend IntelliJ IDEA community with the Minecraft Dev plugin) and download/fork the example mod. That'll give you a good base

Hello, I am trying to create a Minecraft mod with Visual Studio Code using the template provided by Fabric (https://github.com/FabricMC/fabric-example-mod/tree/1.17). When running the mod in the VS Code testing environment both with and without debugging, it works just as expected. However, when I compile it into a jar file and put it into a normal Fabric 1.17.1 installation, Fabric does not seem to recognize it as a mod and just launches without it. Additionally, when I open the jar with 7-zip, there does not seem to be anything specific to the mod. There are no .class files from my code and no assets. It is as if the compiler just puts in the base components, and cannot find the source code or assets. The mod is for 1.17.1. Any help would be appreciated. Thank you.

Are you using the template https://github.com/fabricmc/fabric-example-mod

I started modding using Fabric; specifically a combination of the tutorial on the wiki, reading how other mods do stuff, and asking on the Discord. Once you're familiar with how Minecraft works internally using one mod-loader it's easy enough to transfer to the others (or multiple at once, using Architectury as pointed out), but I wouldn't start off with this. The example mod also gets you a setup you can modify at will.

I've been trying to use this the example mod from github for hours, but I just cannot get it to work. I keep receiving a "build failed" error on startup (something like "filename: failed") with no context to go off of. I have downloaded Java, and Intellij works fine for other coding projects. I have no idea what is causing this.

From the docs

i can confirm what mrspinn has posted but I would use rubidium and not magnesium(both ports of sodium, just a different authors on the ports.), this works with magnesium/rubidium extras as well for things like a better zoom function(runs off the sodium base so both ports are fine). Then if you'd like shaders with this you can use oculus(port of iris), this works with optifine shader packs. Road runner is good for cleaning up a lot of the overhead in things like game physics, AI, block ticking, etc (port of lithium, don't know why this one didn't keep the chemical name). Starlight again is good at what it does, even to the point of being integrated into papermc(which is why it's on their github and not the spottedleaf's personal anymore), don't know if you've sent much time around plugin servers. I also then use Ferritecore this greatly helps bring down memory requirements of the pack(I can run on 4gb, given I have fairly fast memory).

There is a comparison between Starlight, Phosphor and Vanilla on Starlight's Github page

The Mods I would especially recommend for 1.16+ are FerriteCore, Magnesium OR Rubidium (these are incompatible with optifine, for shaders you can use rubidium with Oculus. I would recommend using Magnesium when possible) and Magnesium Extras, as well as Starlight (Starlight X Create if you are on 1.16.5 and are using create) and LazyDFU

And yes, it's safe to use Starlight. I haven't had any data loss, world corruption, etc. and it's a lot faster than Phosphor (At least according to these graphs)

It's just that. It's a free and open source optimization mod that aims to improve fps, and fixes other issues. Along with that, Sodium is free and open source (available on GitHub). By default, Sodium does not provide shader support, and shader support can be done with Iris (Iris is also open source and free as well). But if you want to optimize your fps even more, you can bring in Lithium and Starlight (Lithium targets overall optimization, like the AI and other stuff without breaking the game, and Starlight is a complete rewrite of the vanilla lighting engine to be even more faster and fixes so much stuff with the lighting engine). And you can tack on more mods, like FerriteCore, Enchaned Block Entities (EBE) in order to optimize other parts of the game

Starlight v1.0.0

Source? I can't find it for paper. the Github says it's only for fabric https://github.com/PaperMC/Starlight
