Going to be giving 7dfps a try. The idea is create a first person shooter game in the period of a week. I started with a pretty good base of controls written using the Three.JS library. I took it, and added a simple shoot function. The shoot still needs work, but it's been quite fun learning about 3D!
My current build is here: http://projects.agmprojects.com/7dfps2013. As you can see a lot still needs to be done. I want to customize the ground, to differentiate it more from the starting point, but first i need to get shooting right so you can kill that green ball.
