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.

Settings

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

Addons

To make a ViaFabricPlus addon you just have to implement the ViaFabricPlusAddon interface in your main class:

package net.example;

public class ViaFabricPlusExampleAddon implements ViaFabricPlusAddon {
    
    @Override
    public void onLoad() {
        // called after ViaVersion and 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"
    ]
  }
}

General API

In case you need an event as soon as the idle packet is skipped in the <= 1.8, you can do that:

IdlePacketExecutor.registerIdlePacketSkipExecute(() -> {
    // Called when the idle packet is skipped
});

In case you need the release version of a material, you can do that:

final ProtocolRange range = ItemReleaseVersionDefinition.getItemMap().get(Items.WRITABLE_BOOK); // If an item does not appear in the item map, it has always existed

// The Range class then contains all versions in which the item occurs. 
// You can find out how the Range class works in the ViaLoadingBase README.
// https://github.com/FlorianMichael/ViaLoadingBase

To create a setting group, you can simply use the SettingGroup class:

public class ExampleSettingGroup extends SettingGroup {
    public final static ExampleSettingGroup INSTANCE = new ExampleSettingGroup();
    
    public final BooleanSetting test = new BooleanSetting("Test", false);
    
    public ExampleSettingGroup() {
        super("Example");
        ViaFabricPlus.getClassWrapper().loadGroup(this); // should be in your onLoad method
    }
}
