A cross-platform game engine written in C++, supporting OpenGL and WebGPU rendering backends.

Features

  • Cross-platform rendering, with both OpenGL and WebGPU backends
  • Entity-component system (ECS) based scene model, backed by EnTT
  • Editor with a content browser, scene viewport, and asset pipeline (textures, meshes, materials, tilesets, audio)
  • 2D and 3D rendering, including sprites, text (MSDF font atlases), and static meshes
  • Built-in 2D physics via Box2D
  • Lua scripting support
  • Visual behaviour tree editor for AI
  • Scene and asset serialization

Architecture

Engine architecture overview

Where to go next

  • Getting Started - creating a project and exporting a game with the Editor
  • Behaviour Trees - building AI decisions visually, and scripting custom tasks
  • Lua Scripting - worked examples for giving entities behaviour
  • Components - what each component does, its scene file format and its Lua API
  • Scene Files - the .scene XML format, for writing or generating scenes by hand
  • Lua API Reference - the full scripting API, generated directly from the engine's source
