Small test of WebAssembly with SDL2

A ball is bouncing around the canvas while background music is played. A sound effect played when the ball hits a wall.

Checkout the Demo.

Requirements

Checkout project: git clone --recursive https://github.com/AlbertVeli/wasm_sdl2_test
cd wasm_sdl2_test
make

python -m SimpleHTTPServer 8080
or emrun --no_browser --port 8080 . (add --emrun to linker flags to run this way)
Visit http://localhost:8080/

Audio API - Emscripten only supports SDL_mixer 1. Can be used together with SDL2.
https://github.com/timhutton/sdl-canvas-wasm - Even more minimal example than this

I only got file loading to work together with emscripten by adding --preload-file to CFLAGS. This in turn only works with the _RW versions of the load files. Like Mix_LoadWAV_RW(SDL_RWFromFile("assets/bounce.ogg", "rb"), 1);.
To preload all files in the assets directory --preload-file assets is added to CFLAGS (in Makefile).
Ogg vorbis support is added automatically to SDL_mixer by adding -s USE_OGG=1 -s USE_VORBIS=1 to CFLAGS.
