I was wondering which is the fastest, easiest, and best physics engine for blitz3d out there.
That's like asking "who is the tallest, blondest and funniest actor?" If the answers to all three questions were the same, then everyone would be using that, and no one would be using anything else.
Anyway, Tokamak is almost certainly the easiest. For me, Newton is more accurate and functional than any of the others ( and that includes PhysX if you only want rigid bodies. ) The fastest is probably PhysX, but as NA said, the wrapper writer seems to have gone missing recently. Newton is probably second fastest behind PhysX. ODE was a big letdown for me. Extremely poor friction model ( worse even than Tokamak which is also pretty awful in that regard ) and not even particularly fast.
So I guess my conclusion would be to use Tokamak if easy is more important than accurate and fast, and use Newton if accurate and fast is more important than easy.
