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

## Why?
ViaFabricPlus implements ViaLegacy/ViaAprilFools clientside and adds a ton of fixes that improve the game experience, <br>
as does [multiconnect](https://github.com/Earthcomputer/multiconnect) from Earthcomputer.
### Important: The focus on ViaFabricPlus is on client side fixes, so reporting bugs and contributing is welcome.

## Setting up a Workspace
ViaFabricPlus uses Gradle, to make sure that it is installed properly you can check [Gradle's website](https://gradle.org/install/).
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.

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

## Addons
To make a ViaFabricPlus addon you just have to implement the ViaFabricPlusAddon interface in your main class:
```java
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*:
```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: <br>
```java
IdlePacketExecutor.registerIdlePacketSkipExecute(() -> {
    // Called when the idle packet is skipped
});
```

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