Networking

Communication between servers and clients is the backbone of a successful mod implementation.

Read an overview of why networking matters and the basic strategies in thinking about networking.

There are a variety of techniques provided by Forge to facilitate communication - mostly built on top of [[1]].

The simplest, for a new mod, would be SimpleImpl, where most of the complexity of the netty system is abstracted away. It uses a message and handler style system.

Overview

There are two primary goals in network communication:

1. Making sure the client view is "in sync" with the server view

1. 1. The flower at coordinates X, Y, Z just grew

2. Giving the client a way to tell the server that something has changed about the player

1. 1. the player pressed a key

The most common way to accomplish these goals is to pass messages between the client and the server. These messages will usually be structured, containing data in a particular arrangement, for easy sending and receiving.
