aga engine

aga engine is a small c++23 game engine built around flecs modules. It uses GLFW for windowing/input, wgpu-native for native WebGPU rendering, and GLM for math.

layout

• engine/core: app loop, plugin interface, time, and exit resources
• engine/window: GLFW window resource
• engine/input: keyboard state resource
• engine/transform: local and global transforms
• engine/camera: perspective camera components and helpers
• engine/render: WebGPU renderer facade and mesh components
• demo: a small ECS scene with camera movement and rotating cubes

build

nix develop
cmake --preset native-debug
cmake --build --preset native-debug
./build/native-debug/demo/aga_demo

For wasm:

nix develop
cmake --preset wasm-debug
cmake --build --preset wasm-debug
cd build/wasm-debug/demo
python3 -m http.server 8080

Open http://127.0.0.1:8080/aga_demo.html in a browser with WebGPU enabled. The wasm preset uses Emscripten, GLFW's browser port, and the emdawnwebgpu port. Native builds download the pinned wgpu-native release at configure time.
