tokamak physics thread 4

Blitz3D Forums/Blitz3D Programming/tokamak physics thread 4

I'm sure this doesn't happen in real life, or we would all be floating.

In both versions of tokamak, I have found that if you put a significantly lighter object below a heavier one (or light above a heavy one), the above object will bounce in the air for no reason, and in a very fast manner. I have finally decided to face this glitch upon trying to fix a problem in the rope demo (the crate bounces when it lands on the rope).
So, has anyone else found this problem, and do you have a solution?
A good way to see the effect is by making the tires in the car demo (in the tokamak lib samples folder) very light, and the chassis very heavy.
