Simple game engine written in Odin with a focus on ease of use & extensibility.

Designed to support desktop and web out of the box, though it will likely run anywhere with some tweaks.

Vendored binaries & build scripts are provided for Windows. The web build is using native web technologies and should run on any modern browser. To build/run on any other platform, simply make sure you have SDL3 and its dependencies installed.

Special thanks to the SDL team for their commitment to easy cross-platform game libraries!

Honorable mention as well to W3C for WebGPU & WebAudio, and their committment to open standards.

Current features:

• WebGPU renderer (same feature set on desktop & web)
  • 2D/3D agnostic - sprites in 3D, polygons in 2D
  • full PBR lighting shader
  • shadow mapping with PCF, shadows optional on every light
  • skeletal animation + weighted blending of multiple animations
  • weighted/blended OIT for overlaping translucents
  • automatic batching/instancing for all draws
  • native multi-camera support (for splitscreen, VR, 3D displays, etc)
  • frustum culling per camera
  • basic UI primitives (textured quads + text)
  • OTF font support for both UI & 3D views
• window creation/main loop handling unified for both desktop and web
• fixed timestep for game updates & variable rate for drawing (‘fast vsync’ if available)
• keyboard & mouse input
• basic audio (sound + music loading, playback, looping, fading, spatialization)
• multithreaded actor system with message passing
• basic spatial querying/collision detection
  • 3D Grid with fast nearby/distance queries
  • Sphere, Capsule, AABB, Convex_Hull, Tri_Mesh
  • simple quake-style move-and-slide kinematics over Tri_Mesh colliders
• resource manager, can auto-populate structs with loaded resources
  • can save/load those structs from json as well
  • can also embed resources into the executable
• file format support:
  • textures
    • png & jpg supported on both desktop & web, other formats vary by platform
  • static meshes
    • obj
  • scenes/animated meshes:
    • gltf
  • audio:
    • ogg, wav, mp3 supported on both desktop & web, other formats vary by platform

Planned major features:

• exporting engine functionality to shared libraries
• FFI wrappers for various scripting languages (Python for my wife)
• dynamic mod loading on desktop platforms
• deterministic gamestate, serializability, saving and loading
• minor features listed in TODO.org

Not planned:

• level editors/high level format support (other than glTF)
• GPU/vendor/OS specific features
