A 2D Game Engine Framework for people who want complete control over how their game is built.
There is no visual editor. No scene graph. No inspectors.
When you start the engine, you get a blank window and build your game directly in code.
If you enjoy low-level, fast iteration, and designing your own architecture, Lily2D is made for you!
Swamp: Build gameplay, rendering logic, and even server-side logic in Swamp, a deterministic custom language designed for fast iteration.
WebGPU: Highly customizable shader-based pipelines with WGSL on top of WebGPU. Includes math utilities for vectors, matrices, and quaternions.
Software Synth: Play audio using Ogg Vorbis or WAV, stream music and shape playback with ADSR envelopes.
Gamepad and Mouse Input: Gamepad-focused input, with support for a single keyboard and mouse.
Networking: Send and receive unreliable UDP datagrams using a custom non-encrypted protocol designed for games.
Persistence: Save user settings and save-games in a platform neutral way.
Font Loader: Load BMF format, a specialized, high performance font format for games.
Platforms: Export your game to Windows, macOS, Linux, and SteamOS.
