Doing a search for "Unable to create 3D scene", I found several matches, and they all appear to have to do with dx or video drivers. So it doesn't appear to be the BAIT demo that's the problem
I agree, I do have a fairly old computer and I haven't been able to run some other 3D games the Blitz community has produced, but how was I able to run the last demo and not this new one? Could you maybe add some debugging code to the demo so that I can give you feedback as to when the error's occuring?
Are you suggesting that all arenas are symmetrical in nature then?
I suppose symmetry would be the fairest and nicest looking option, but I wouldn't mind completely random placements of objects and bots either.
