Lance is a real-time multiplayer game server

It provides an extendible Node.JS based server, on which game logic runs, as well as a client-side library
which synchronizes the client's game state with the server game state. In order
to provide a smooth visual experience for each connected client, Lance implements
efficient networking methods, position interpolation and extrapolation, user input
coordination, shadow objects, physics and pseudo-physical movement, automatic
handling of network spikes.

Lance aims to optimize the player's visual experience, while providing
a simple development model which is highly configurable and easy to analyze
and debug.

Features:

* Focus on writing your game. Lance takes care of the netcode
* Can support any type of game or genre
* Optimized networking
* TCP via websockets
* Communication is packed and serialized into binary
* Automatic handling of network spikes with step correction
* Intelligent sync strategies for lag handling
* Extrapolation (client side prediction) with step re-enactment or:
* Interpolation for optimal object motion
* Tools for debugging and tracing

More features in the pipeline:

* UDP via WebRTC
* Full-stack testing suite
* Replay saving
* More physics engines

That's so neat! Where do I start?

The official Lance documentation contains articles on theory and rationale, as well as the structure and architecture of the project.
