Networking
Communication between servers and clients is the backbone of a successful mod implementation.
There are two primary goals in network communication:
- Making sure the client view is "in sync" with the server view
- The flower at coordinates (X, Y, Z) just grew
- Giving the client a way to tell the server that something has changed about the player
- 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.
There is a technique provided by NeoForge to facilitate communication mostly built on top of netty.
This technique can be used by listening for the RegisterPayloadHandlerEvent event, and then registering a specific type of payloads, its reader, and its handler function to the registrar.
