Platformer with physics

Platformer with physics

I've just started writing a generic platform game engine, a project
which is going to be a test for my C#/Director environment as well as
some Shockwave games.

To get started quickly, I run a Havok simulation in the background that
handles the physics. Of course, I'll have to move away from that
solution when porting, but I think I'll use it a while. I haven't used
Havok before, and there's one problem with my current simple setup.

Some properties of what I've got now:
* Levels built from bezier curves, converted to mesh
* Allow for Sonic-like gameplay (running in loops etc)
* Balls and boxes that can be moved around, slide on slopes.

Using standard Havok, moving boxes over edges makes them tip and tumble,
which doesn't feel very platform-game-like. I'd like them to stay until
their whole base is over the edge, then drop without rotating. I've got
some ideas, but they'll probably take me quite a while to evaluate.

Anyone solved such a problem? Anyone that is a few hundred dollars from
a solution? I can specify further if someone's interested.
