netcode.io.net is a transpile of netcode.io.
netcode.io is a connection-oriented protocol built on top of UDP.
It's designed for use in client/server games with dedicated servers.
It has the following security features:
- Protection against man-in-the-middle attacks.
- Protection against DDoS amplification attacks.
- Protection against packet replay attacks.
- Protection against zombie clients.
netcode.io has been used in several AAA game projects and is stable and mature.
Please refer to the second half of this whitepaper: Why can't I send UDP packets from a browser?
For a complete technical specification, read the netcode 1.02 standard.
This repository holds the implementation of netcode.io in C.
Other netcode.io repositories include:
- netcode.io C# implementation
- netcode.io Golang implementation
- netcode.io Rust implementation (updated fork of vvanders/netcode.io)
- netcode.io for Unity
- netcode.io for UE4
- netcode.io browser plugin
