# [Lance](https://lance-gg.github.io/) 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](https://lance-gg.github.io/docs_out/index.html) contains articles on theory and rationale, as well as the structure and architecture of the project.
