Networking

This page describes how to use the 'ModernNetworking' of CraftedCore.

For Minecraft 1.20.5+, you need to additionally register the packets the server might receive (C2S): ModernNetworking.registerType(packetId);{:.language-java .highlight} {:.note}

Sides

Valid sides are S2C and C2S, where S2C describes Server-To-Client and C2S describes Client-To-Server.

Receiver

Code, that will be handled once the package is received.

class ImplReceiver implements Receiver {
    @Override
    public void receive(Context context, CompoundTag data) {
        // read data from the data tag and handle it
        context.getPlayer(); // returns the player that either send or received the package, depending on:
        context.getEnv();
    }
}

Registering Receiver

Must be run for every packet, no matter if it's C2S or S2C.

ModernNetworking.registerReceiver(side, packetId, receiver);

Sending Data

Sending data to a player (server only):

ModernNetworking.sendToPlayer(serverPlayer, packetId, data);

Sending data to the server (client only):

ModernNetworking.sendToServer(packetId, data);
