The book will finally be done, its been one helluva ride, and right at the death I've had a major unfixable problem with a model (need the artist to fix it) but I have been completing the write ups on some of the more technical aspects of the code
Physics and terrain collision for example
Here's an example of a tile based environment with full terrain collision in place, and a god camera to view it all. It chugs a bit since the wireframe draws are painfully slow, but its a debug option.
Animations, culling, lighting, cameras, shadows in shaders, and other bits all done so I'm just waiting for a model fix to finish it all off.
Its a lot of work, perhaps I didn't get quite the gameplay in there I wanted but thinking about it, explaining how to write a particular game wasn't the idea, explaining how to write multuple games using the techniques explained makes more sense.
I hope this model I need gets fixed asap, or I will have to find an alternative way to explain a final point...or scrap it and wrap it up.
