[ODE] Any BloodRayne 2 developers listening?

[Jani Kajala]

Derek,

I haven't worked on BR2, but I do have done (stable) 3rd person game demo
using ODE, in which the character is simulated body with capsule collisions.
(for my co-authored book, 'Making Game Demo', hopefully to be published
before Christmas by WordWare)

Briefly what I did:

1) Updated the simulation 100x/sec

2) Didn't set body's velocity directly, used impulses

3) Aligned rotation manually between steps (could have used AMotor too I
guess)

4) Used global ERP of 0.2 and following contact settings: mode =
dContactBounce+dContactSoftCFM; mu=0; bounce=0.1f; bounce_vel=0.01f;
soft_cfm=0.000001f.

If you're interested drop me an email (jani.kajala (a) helsinki.fi) so that
I know to keep you in the loop about the book. I'll release (if I can) all
the source code in the book anyway so you can check it from there too even
if you don't want to buy the book.


Good luck,
Jani
