## What it is
toy is a thin and modular C++ game engine built on top of the 'two' library, aiming to provide the simplest technology stack for making 2D and 3D games directly in C++. It offers a programmable 3D renderer, entities, physics, navmesh navigation, procedural generation helpers, and zero-cost tools, editors, and scripting extensions.

## Use cases
- build a 2d or 3d game in c++
- create a custom game engine from reusable building blocks
- prototype games with fast iteration cycles
- implement procedural generation in a game
- build games with complex custom ui and rendering schemes
- generate navmeshes and pathfinding for game ai
- compile a game to webassembly for the browser

## When to choose
- you want a lightweight, hackable c++ game engine with a small codebase
- you need full control over shaders, materials, and render paths
- you are building games with atypical constraints like complex ui or procedural generation
- you want to assemble your own game technology from minimal reusable components

## When to avoid
- you need a stable, production-ready engine with documentation and guaranteed stability
- you want a permissive license for commercial use without GPL obligations
- you prefer batteries-included engines like Unity, Unreal, or Godot
- you need long-term support or an active release cadence

## Facets
- artifact type: framework
- maturity: experimental
- function: game-engine, graphics, ui-components, audio-processing, simulation
- domain: graphics, cross-platform
- platform: cpp, cross-platform, wasm
- tags: game-engine, cpp, modular, procedural-generation, physics, navmesh, rendering, editor, scripting, game-development
