Introducing the NKTg Law: A Simulation of Variable Inertia in C

[wolle2]

I noticed you've been quite active with this topic on the net lately, even referring to variable-mass as a new philosophical perspective .

Anyway, the subject seems quite well studied:

I suggest you start by reading up on computer simulations in general and develop a mathematical model. Then turn it into code in your favourite language. The information you posted here is too meagre to give any meaningful help. Maybe, you should consider teaming up with an experienced game developer.
