New Revision: 755
URL: http://svn.gnome.org/viewvc/seed?rev=755&view=rev

Log:
added horribly dirty ugly pong in clutter. it's horrible. don't even open it. it's the worst code ever. it was more of a "rush to implement something really really fast" thing with Matt. I'll fix it tomorrow, add networking, scoring, fix accelerations and stuff, make the AI LOSE at some point, etc.



Added:
   trunk/examples/pong.js   (contents, props changed)

Added: trunk/examples/pong.js
