I heard there was an editor for gpl that stops the cpu cars ai improving as
you get faster. Could someone let me know where to finf this editor.
thanks

I'm not sure if they do get faster as you get faster (I am new to GPL
however, so I could be wrong), but you could try downloading the AI
Patch for GPL from www.theuspits.com

Works a treat!

I know it gets faster cause at the Ring the first race ever Clarck had the pole
with a 8:30.xx and i was running 10:10.xx.  Now that im into the 9:10 zip code
hes getting pole with about a 8:10-15.  Definately faster than before.

I think you're referring to GPal, which is due for release any day now
(apparently) ;-)

Anyway, Jack Rambo will probably fill you in on this one.

You can prevent the AI from getting faster as your times improve by
altering the following line in the gpl_ai.ini file inside the GPL
directory:

        npt_override = 1

(npt stands for "normalised player time", I think).

Note that the faster drivers (Clark, Hill etc.) don't take much notice
of the npt anyway - it's very noticable further down the field, though.

The problem is that if you can only run against a few AI cars because
your computer is too slow, then it picks the top 5 drivers, then
altering this will make very little difference.

To fix this you need to renumber the drivers in the driver.ini file so
that the slower guys are numbered 1 to 5 - then you can race against
them.

I believe Alison Hine explains all this on her GPL page at

    http://www.simracing.com/alison/gpl/index.htm

There's an AI tweak page here:

Setting npt_override = 1 will disable the  Normalized Player Time system and
cause the AI to run at their baseline speed (i.e. Papy's approximation of
the '67 lap times...quite fast for the average sim racer). To run faster
than baseline, set npt_override to a value below 1.0 and to run more slowly,
set the value above 1.0.

Each AI driver's reaction to changes in npt_override is a function of each
driver's global_hype_scaling setting (found in the Driver.ini file). As Neil
indicated, the slower drivers in GPL have, by default,  larger
global_hype_scaling settings so they are more dramatically affected by
changes in npt_override.

To re-enable the NPT system set npt_override=0.

If all this sounds like a chore, it is! The best solution is to wait just a
bit, say good-bye to editing INI files, and do it all with the GPaL
interface. With two point-and-click controls, you'll be able to control both
the speed of the AI field and the range of speeds within the field. And GPaL
remembers your AI settings for every combination of Driver, Track, Car, Car
Type, Mode, and Level! As you change any of these settings, the AI
automatically adjust to match your settings for your new selections.

With this kind of ease of use available, there's no better way to develop or
hone your driving skills than to train with an AI field that is ideally
matched to your current driving skills. What's more, it's incredibly fun!

If you haven't seen GPaL, take a look at the Sneak Preview at
www.RaceLive.com/GPaL and make sure you get on the mailing list so that you
will be among the first to download it when it's available.

Gotta cross the finish line first, Jack. ;)

If you want a real easy way to slow the AI in GPL, open up the
gpl_ai.ini file and edit the line:-

base_gearshift_hiatus

Its about 3 lines down under the [behaviour] heading.

This represents the amount of time the computer cars take to go from one
gear to the next.  The higher the setting (before the decimal point),
the longer they take to change up and hence the slower they will be.

So whilst they're trying to find that next gear on the straights you can
nip by :-)

It may seem like sacrilege to some, but hey its better than seeing those
AI cars disappearing into the distance whilst your getting to grips with
the game >:-(

Another way of going about this is to edit the line:

rolling_drag_amt =

This ends up controlling the amount of acceleration the AI cars
have down the straights.  The default value is too low which
explains why the AI cars seem to be flying down the straights.
I use 0.07 whenever I step into the Brabham in order to even
up the competition.  With this adjustment they will reach top
speed at about the same point you would.

For some added fun set it to a real high value for that weaving
through rush hour traffic experience.
