I release as Open Source of my IGF entry for Main (and hopefully Student) competitions:
Sens3s: The Art of Understanding - http://www.igf.com/php-bin/entry2012.php?id=498
Whole Engine is commented and provides support on following extensions:
Raycaster Engine (whole game is created for this extension)
Open AL for surround sound
Fog of War effect used to simulate player blindness - Layers and Alpha channels (HWA enabled)
Also as an addon I provided open source example of my updater based on Get, Download and Archive objects.
Download it from website:
I don't want direct downloads, as well as I can't add the file as attachment so don't flame because of that.
