FR-AI / ANALYSISWhy it is worth attention
It combines a full-featured ECS, PBR rendering with post-processing, a dockable editor with live play/stop and asset management, Lua scripting with hot-reload, Jolt physics, and miniaudio audio—all built from scratch and well-documented.
Who it is for
- Indie game developers building small 3D games
- C++ programmers interested in engine architecture
- Students learning game engine design and implementation
- Developers seeking a feature-complete but lightweight ECS-driven engine
Use cases
- Creating a 3D game like the included Orb Hunt demo
- Prototyping gameplay using ECS and Lua scripting
- Learning how to build a modern game engine from scratch
- Developing editor-integrated tools for level design and asset browsing
Strengths
- Sparse-set ECS with versioned handles and a system/resource runtime
- Modern OpenGL 4.1 renderer with PBR, shadow maps, IBL, and a post stack (bloom, tone mapping, FXAA)
- Full editor (forge) with dockable viewport, click-to-pick, gizmos, play/stop scene snapshots, and asset browsing
- Lua scripting with hot-reload and inspector-editable fields, plus integration with physics and audio
Considerations
- Only supports macOS and Linux; no Windows or other platforms yet
- Single-developer project still under active development
- Requires building from source with C++20, CMake 3.24+, and no pre-built binaries
