ViaAprilFools

ViaVersion addon to add support for some notable Minecraft snapshots.

ViaAprilFools itself runs on Paper and Velocity servers and can be implemented in any other platform which supports ViaVersion.

If you are looking to implement ViaAprilFools in your own software you can start by reading the Usage section.
If you just want to use ViaAprilFools yourself you can check out some projects which implement it in the Projects section.

Releases

Gradle/Maven

To use ViaAprilFools with Gradle/Maven you can use the ViaVersion maven server:

    maven { url "https://repo.viaversion.com" }
}

dependencies {
    implementation("net.raphimc:viaaprilfools-common:x.x.x") // Get latest version from releases
}

    </dependency>
</dependencies>

Jar File

If you just want the latest jar file you can download it from GitHub Actions or the ViaVersion Jenkins.

Usage

ViaAprilFools requires you to have an already functional ViaVersion implementation for your platform. If you don't have one you can check out ViaLoader for an abstracted and simplified, but still customizable implementation. You can also go to the other ViaVersion repositories and look at their server and proxy implementations.

Base Implementation

ViaAprilFools platform implementation

To get started you should create a class which implements the ViaAprilFools platform interface. Here is an example:

public class ViaAprilFoolsPlatformImpl implements ViaAprilFoolsPlatform {

    public ViaAprilFoolsPlatformImpl() {
        this.init(this.getDataFolder());
    }

    @Override
    public Logger getLogger() {
        return Via.getPlatform().getLogger();
    }

    @Override
    public File getDataFolder() {
        return Via.getPlatform().getDataFolder();
    }

}

This is a very basic implementation which just uses the ViaVersion logger and data folder.

Loading the platform

After you have created your platform implementation you should load it in your ViaVersion implementation. Here is an example:

Via.getManager().addEnableListener(ViaAprilFoolsPlatformImpl::new);

Make sure to add the enable listener before the Via manager is initialized (((ViaManagerImpl) Via.getManager()).init();).

Note

If you want your platform to support the client protocols, you need the override the getClientProtocol function in your version provider:

@Override
public ProtocolVersion getClientProtocol(UserConnection connection) {
    final ProtocolVersion version = connection.getProtocolInfo().protocolVersion();
    if (version.getVersionType() == VersionType.SPECIAL) {
        return ProtocolVersion.getProtocol(VersionType.SPECIAL, version.getOriginalVersion());
    } else {
        return super.getClientProtocol(connection);
    }
}
