This is a Chocolate Doom WebAssembly port with WebSockets support.
You need to install Emscripten and a few other tools first:
brew install emscripten
brew install automake
brew install sdl2 sdl2_mixer sdl2_net
There are two scripts to facilitate compiling Wasm Doom:
./scripts/clean.sh
./scripts/build.sh
Copy the shareware version of doom1.wad to ./src (make sure it has the name doom1.wad)
Then:
cd src
python -m SimpleHTTPServer
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
doom: 12, client '%s' timed out and disconnected
