[Torcs-devel] Rolling resistance in SimCarUpdateSpeed

[Bernhard W. <be...@bl...>]

Hi all

I reviewed SimCarUpdateSpeed and have the opinion that the rolling resistance
code in it must be removed, here is why (if no good arguments against this are
found or it causes terrible side effects I will do it soon):
- in SimCarUpdateForces the rolling resistance is already considered and
influences the acceleration
- in SimCarUpdateSpeed the new velocity is computed with the acceleration (which
already contains the rolling resistance), so we do it currently sort of twice
(it is a bit more complicated, the code has terrible side effects on surfaces
with large rolling resistance (try e.g. 0.12).

So what do you think?

Thank you,

Bernhard.
