A tutorial that builds a game
Seven short parts take you from an empty project to a two-level game with a character, physics, coins and a score, with every script explained.
Cairn
A 3D game engine you can drive by hand or by agent
C++20 on Vulkan, with an editor, Lua or TypeScript scripting, physics, audio, animation and one-command export for Windows, macOS and Linux. The code is private for now and will be open source soon.
Learn Lua from nothing
A six-page course in the scripting language, written for people who have never programmed, with a cheat sheet for people who have.
An editor that stays out of the way
Click to select, drag assets into the scene, undo anything. A project hub with templates gets you to a playable level in a minute.
Lua or TypeScript, with hot reload
Game logic is plain Lua files, or TypeScript the editor compiles to Lua. Save one while the game runs and the new code is in use at once, with values kept.
Built for AI agents
Everything the editor does is also a JSON command. An agent can make a project, build a level, play it and export it with no window.
Modern rendering
PBR materials, image-based lighting, cascaded shadows, ambient occlusion, bloom, ACES tonemapping and FXAA.
Physics, audio and animation
Jolt physics with a character controller, 3D sound with music streaming, skinned meshes with animator state machines.
Export in one step
A project becomes a standalone game, with its files in one pack and no editor code inside.
