Web build (WASM)

[nathanleiby]

Why?

Way easier to share and ship iterative improvements.

How?

• [x] Get any working web build, even if degraded UX (latency? midi?) - hooked up to GH pages (here)
• [x] Figure out better build toolchain to incorporate Rust libraries that support wasm bindgen
  • https://github.com/not-fl3/macroquad/issues/212#issuecomment-1944760503
  • https://github.com/brettchalupa/sokoworld/blob/09ce68c690cbae0db242ab1b403c309f8b8482d2/release_wasm.sh
  • https://mq.agical.se/release-web.html
  • https://github.com/ozkriff/awesome-quads?tab=readme-ov-file#example-usage
• [x] Get time to work
• [x] Get audio to play
• [x] Fix flashing screen bug -- fixed in https://github.com/nathanleiby/drum-break/commit/f4999f1eb231dd4eadd1b601f1993be5ffebf60a
• [x] Get midi working -- right now it prompts for a device connection but doesn't seem to read any input data -> fixed here https://github.com/nathanleiby/drum-break/commit/8aacf27c762306d51d9c8c3311225948881163ae
• [x] Get loops to show -- right now the right panel loops dropdown says "no loops" - used include_dir 0559636573ce08be0c10289d52d0f236db02b1b5
• [ ] Fix or remove confy
• [ ] To achieve #1, figure out how to store data in web context (local storage? remote datastore?)
  • idea: quad-storage

Good progress on WASM build today: https://github.com/nathanleiby/drum-break/compare/4c9c9fa9b8288da73a8d4ce7d382851b33cf822a..66bff4c5c09eb538acbf986744526477392169c4

Got a build working that lets me keep Macroquad with its special wasm build toolchain, but include other wasm-bindgen deps! Much thanks to https://gist.github.com/tgolsson/d78f7887a8542f3fd6f125070e5e22d6?permalink_comment_id=4901010#gistcomment-4901010

One obvious issue has cropped up. The screen is flashing sometimes in WASM build. This is a reported issue for Macroquad web builds: https://github.com/not-fl3/macroquad/issues/471#issuecomment-1346563191

In that case, it was due to loading a resource during the loop in a way that's expensive. Could that be my issue? It seems to flash just before a sound is played

• ... is that when audio is being scheduled?
  • Interestingly, if there are multiple sounds in close succession it seems NOT to flash for each
• .. does it have to do with fetching the data?
  • revisit idea of loading sound 1x and then cloning each instance for performance

Whatever my fix is, I should chime in on the Macroquad issue and share context. Maybe they can close the issue out if it doesn't seem to be a Macroquad isue. Contributing in some way to macroquad is one of my RC goals for the upcoming weeks!
