*Sigh* Ok then. What about the rest of you? Any interest?
Here's a couple of carefully staged screenshots of my attempt (currently named Rho-bot):
So far I have the basic controls in place (look / walk / jump / fire). The weapons will fire, but there is virtually no collision detection at the moment, so you can walk through buildings which I created with Google SketchUp. It's easy to use, but I'll have to see how effective I can get the collision detection working with that.
