Adjusting car parameters in N4?

Adjusting car parameters in N4?

by Kendt Eklu » Thu, 15 Mar 2001 07:13:01

Has anyone determined if its possible to tweak car parameters like
weight, wheelbase, and power in N4?  This wouldn't be for on-line
cheating, but to simulate a Busch car more accurately, and only for
practice modes.  Anyone on the TPTCC team with this info?

TIA!

Chances are it is possible.  If you look in the file papy_ai.ini there is
the following section:

; *************************************
; CAR CLASS PARAMETERS
; *************************************

[ CUP ]
braking_efficiency_coeff = 0.94             ; value * adj_traction_circle =
max. decel
nominal_max_accel = 0.006806                ; accel. in meters/tick^2 (1G =
0.007562)
nominal_traction_circle = 0.0135            ; same units as accel.
(meters/tick^2) -- 1.78 * ONE_G

Then if you look in the series folder there is a cup folder.  My guess is
that there will be a truck and a busch folder in the series folder for the
cars/trucks add-on which is bound to come out with additional sections in
the papy_ai.ini file for them.

Cheers

Phil

The followup is how do you get it to go into 'Busch' mode *now*?  I've got a
few Busch cars ready to race... :)
