ViaFabricPlus

Clientside ViaVersion, ViaLegacy and ViaAprilFools implementation with clientside fixes for Fabric

This project has nothing to do with the original ViaFabric and is therefore also not compact

Why?

ViaFabricPlus implements ViaLegacy/ViaAprilFools clientside and adds a ton of fixes that improve the game experience,
as does MultiConnect from Earthcomputer.

Important: The focus on ViaFabricPlus is on client side fixes, so reporting bugs and contributing is welcome.

Project structure

ViaFabricPlus splits into two major parts:

Part	Description
ViaFabricPlus	Core of the project, all fixes here are stable and have been tested many times
ViaFabricPlus-Visual	Addon for the core, it adds only visual changes between the versions like old textures, optional and not necessary for the gameplay, but recommended.

Setting up a Workspace

ViaFabricPlus uses Gradle, to make sure that it is installed properly you can check Gradle's website.

1. Clone the repository using git clone https://github.com/FlorianMichael/ViaFabricPlus.
2. CD into the local repository.
3. Run ./gradlew genSources.
4. Open the folder as a Gradle project in your preferred IDE.
5. Run the mod.

Tip for developing Addons: the installAddons task automatically copies all built Addons to the run/mods folder of the main project

Values

Values are optional settings that can turn fixes on and off, originally they were used for debugging

Addon-API

For ViaFabricPlus-Visual and other future addons an AddonAPI has been developed to make it easier to access ViaFabricPlus,
to make a ViaFabricPlus addon you just have to implement the ViaFabricPlusAddon interface in your main class:

package net.example;

import de.florianmichael.viafabricplus.ViaFabricPlusAddon;

public class ViaFabricPlusExampleAddon implements ViaFabricPlusAddon {
    
    @Override
    public void onPreLoad() {
        // called directly after Via* is initialized
    }
    
    @Override
    public void onPostLoad() {
        // called after Minecraft is initialized
    }
    
    @Override
    public void onChangeVersion(ComparableProtocolVersion protocolVersion) {
        // called when the user changes the target version in the gui
    }
}

To load the addon you have to specify the addon main class as entrypoint in your fabric.mod.json:

{
  "entrypoints": {
    "viafabricplus": [
      "net.example.ViaFabricPlusExampleAddon"
    ]
  }
}
