Emscripten port of ioquake3

ioq3.js

ioq3.js is a simple port of ioquake3 to the web using Emscripten. It was heavily inspired by inolen's quakejs, but aims to be simpler and up-to-date with the latest Emscripten features.

Demo

You can play the demo version here.

Building

make PLATFORM=js EMSCRIPTEN=/path/to/emscripten

Binaries will be placed in build/release-js-js.

Adding data

Data is preloaded using Emscripten's virtual filesystem. So, if you want to play, you have the provide the official (or demo) PK3's. Here's how it would work for retail Q3:

python /path/to/emscripten/tools/file_packager.py emscripten_data.data --preload baseq3 > emscripten_data.js

And add this to the build/release-js-js/ioquake3.html file:

<script async type="text/javascript" src="emscripten_data.js"></script>

Running

• Run python -m SimpleHTTPServer 8888 in build/release-js-js
• Load localhost:8888/ioquake3.html in your browser
