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.

- 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
That's so neat! Where do I start?
To get a bird's eye view on what's Lance all about and how to use it to make a multiplayer game, we recommend reading the guide: Architecture of a Multiplayer Game
If you're more of the learning-by-doing type, you can start with the first tutorial, My first game: Pong which contains step-by-step instructions on how to implement a networked version of this classic game.
