This is a Chocolate Doom WebAssembly port with WebSockets support.
Using nix a result symlink including all targets except the WAD file can be built:
nix build .#doom-wasm
Start a nix shell or use nix-direnv to get the required dependencies.
nix develop
For the first build use:
./scripts/build.sh
Which will build in the source tree src/. From there you can also use make
to incrementally build targets.
Copy the shareware version of doom1.wad to ./src (make sure it has the name doom1.wad)
Then:
curl https://distro.ibiblio.org/slitaz/sources/packages/d/doom1.wad -o src/doom1.wad
simple-http-server -i src
Then open your browser and point it to http://0.0.0.0:8000/
Doom should start (local mode, no network). Check doom-workers if you want to run multiplayer locally.
Inspect src/index.html for startup details.
Check our live multiplayer demo and blog post.
To show important messages coming from the game while it's running we send the following formatted stdout messages, which can be parsed in the web page running the wasm:
doom: 1, failed to connect to websockets server
doom: 2, connected to %s
doom: 3, we're out of client addresses
doom: 4, ws error(eventType=%d, userData=%d)
doom: 5, ws close(eventType=%d, wasClean=%d, code=%d, reason=%s, userData=%d)
doom: 6, failed to send ws packet, reconnecting
doom: 7, failed to connect to %s
doom: 8, uid is %d
doom: 9, disconnected from server
doom: 10, game started
doom: 11, entering fullscreen
