PacketAPI
Minecraft Java mod. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForge
PacketAPI is designed to make networking easier in Minecraft.
Briefly:
- No more handlers for each packet, keeping OOP style and processing synchronous
- Registering packets without the need to specify descriminators and other things
- Callbacks. Sending requests to the server and asynchronously waiting for a response, and then processing the result synchronously, all in one line of code
- Control over packages. Suppression of spam with packets of one annotation
- Rich functionality for sending packets in packs with filtering and black jack
- Converting Object <-> byte[] without pain
- Full BukkitAPI and Forge support
- Lazy data sending without packets
- The author's method of packing data, similar to serialization, but with optimization of the weight of objects up to 4.5 times
Usage examples
It looks like CurseForge doesn't support source code blocks. Therefore, examples are on Github.

Install
Go to Files and download one of them.
ACHTUNG! PacketAPI was developed for Minecraft `v1.7.10` and `v1.12.2` and works correctly there. It does not mean that it will
definitely fail on other versions, but you should use it at your own peril and risk.
p.s. use a jar file called `packetapi-@VERSION@-no-reobf.jar` if you cannot run the game with this library from the IDE.
It's possible when working with `Minecraft v1.7.10`
