This is a basic example cart in C for the null0 game-engine.

usage

Carts run natively, and on the web. This repo will auto-publish to github-pages on push, so users can check out your cart without installing anything.

They can also install the native runtime and use it to run your cart.

github

There are 2 actions:

• Publish demo to github-pages - this happens on any push
• Attach current version of your cart to any releases that are created (like here)

developing

Make sure you have wasi-sdk installed and WASI_SDK_PATH set to it's location (eg /opt/wasi-sdk.)

Then you can do this:

$WASI_SDK_PATH/bin/clang src/main.c -o src/main.wasm
cd src
zip -r ../webroot/mygame.null0 . -x '*.h' '*.c'

You can also use cmake (recommended) to build a complete cart:

cmake -B build -DCMAKE_TOOLCHAIN_FILE="${WASI_SDK_PATH}/share/cmake/wasi-sdk.cmake" -DCMAKE_BUILD_TYPE=Release
cmake --build build

You will find your cart in webroot/mygame.null0

If you have node installed, you can also get a nice watching-webseerver, locally:

npm start

After this, create a github-release, and your cart will show up on releases (like here).
