Here I will post my AI updates for various tracks. I had uploaded some of my files and they are somewhere here at forum. But I like to keep them in one place.

Updates for tracks:
*At tracks like Reims and Hockenheim I tried to increase passing on straights. So lp files has many  passing flags. Original game supports only 24 passing flags. But for example I placed something like 50 passing flags around Reims. So you need mod's patches that enable long track support.

Pavel, can you be more specific about the year for Hockenheim, Oulton park?
I'm adding referrals to this page for the tracks you made ai for so people will find them here.

Pavel, top-notch work, my friend!  I have tested Snetterton '64, Crystal Palace and Oulton Park with the '65 Mod..... excellent AI behaviour - both realistic and challenging.  :)

Thank you!!  :)

I tried the Reims update last night and it was better than before. The AI did a lot more overtaking. Many thanks, Pavel.

thks Pavel ; I see for Reims, the race and pass files are depending on the mod 66 or 67 we use .

For Edmonton, do you advise us that your track.ini shld be used instead of the tra71ca.ini ?

Yes, there are some mod specific files in my updates. I will try to explain the way GPL use this AI files so you may decide how to use them. All this was found during various tests. I don’t know why it works that way.

Original game (or source gpl.exe that is used by GEM to generate all other executables) for every track need set of lp’s and track.ini file.

Lp’s control AI racing line around the track, also race.lp (and occasionally pass1 and pass2) controls cars longitudinal and lateral speeds. GPL.exe directly uses values from this files.

Track.ini contains various values that control AI behavior on track. There are also seven strings for AI to calculate fuel load:
brabham_fuel_load_per_lap = x.xx
brm_fuel_load_per_lap = x.xx
coventry_fuel_load_per_lap = x.xx
eagle_fuel_load_per_lap = x.xx
ferrari_fuel_load_per_lap = x.xx
lotus_fuel_load_per_lap = x.xx
murasama_fuel_load_per_lap = x.xx
This is amount of fuel that is needed to complete one lap for every car model controlled by AI.

All this seven strings can be replaced with single one:
nominal_fuel_load_per_lap = x.xx
It forces AI to use this amount of fuel for very car model.

That was easiest part. Now I’ll try to explain how this files work with mods.

Firs of all, patch 1.3 for original game it’s not a simple patch. After applying it original game.exe remains. But you also get new gplc67.exe with 1967 F1 season. This is mod. It’s behavior is different compare to original gpl.exe. Original executable still use track’s AI files like I’ve described above. But gplc67 use them different way.

I guess Nigel Pattinson try to make game feature that helps mods to use original lp’s and track.ini files. Original lp’s contain speeds for 67 F1 cars. They maybe will not work well with 65 F1 cars or 67 GT cars. Or fuel load that is set in original track.ini will be to high for 65 F1 cars, ot too low for 67 GT cars. So some sorts of coefficients were implemented. But also he created possibility to have mod specific AI files that still will be directly used like original executable do.

Lp files
All mods adjust speeds from common lp’s (even F1’67). Most of them do it ok, but GT’67 and CA’71 have some problems. Mods use directly speeds only from mod specific lps (*.l65, *.l66, *.l67 etc.).
I prefere:
1) to use F1’67 (gplc67.exe) with mod specific lps - *.l67. That way AI use actual speeds from lps that were made from 1967 replays in most of the cases. I usually make a copy of race.lp, pass1.lp and pass2.lp and put them in track folder with l67 extension (race.l67, pass1.l67, pass2.l67)
2) to use GT’67 and CA’71 mods only with specific lps made from appropriative replays. I released my GT files. I had whole set of CA’71 specefic lps, but I don’t know how it’s better release them.
3) to use F1’65, F1'66, F1’69 (original and extra), F2’67 mods only with common lps. There is no much difference compare to using of mod specific files.

Note: Most of latest tracks lps are generated with AIEdit tool. Speeds inside such files are also generated but this tool. If you made mod specific lps from them AI cars will have unreal acceleration and sometimes too low speed in turns.


Track.ini files

All mods
If common track.ini is used game calculate average fuel load from values in seven strings, apply some coefficient (I’m not sure if there coefficient for F1’67) and use resulted fuel load for every car.

(brabham+brm+coventry+eagle+ferrari+lotus+murasama) / 7 * K

Or it can be replaced with single Nominal fuel load for which also coefficient will be applied.

F1’65, F1’67, F1’69 (original)
If mod specific track.ini is presented (track65.ini, track66.ini, track69.ini) then fuel loads for every car model are used independently.
So for F1’67 it’s better to have track67.ini in track folder (just a copy of common track.ini).

F1’66
Mod specific track66.ini has 16 fuel load strings for evry car model. Each setting are used independently by mod.

F1’69 (extra)
Unlike 1966 mod here there wasn’t implement option to have individual fuel load setting for every car model. Fuel load settings are used like with common track.ini file.
I don’t use original 1969 mod anymore. So I replaced seven fuel strings with single Nominal using brabham fuel load here.

GT’67 mod uses its own fuel strings which are used independently.

CA’71 mod uses only single string (brabham) for all cars.

F2’67
This mod has some bugs here. It needs fuel load settings for every car model, but it use them to calculate average setting that is used for every car. I will explain in soon, when will upload F2 AI patch.

No. Tra71ca.ini should be used. Maybe only with some speed adjustments.

Wondering...are there any Ai-files made maybe better for the default 67 tracks...Kyalami, Monaco...and so on  :)

Thanks !!

Thanks for all your ai work pavel really appreciate it. :)

Do you think you could take a look at the lp files for Syracuse 67? I think I have the latest files for it but the ai always hit the wall at the corner before the first hairpin. The rest of the track is fine.

My opening post was updated.

I made small update for Snetterton 1964. First time I forgot to add second tire warmup flag so AI cars needed more time to heat up tires.
Also I add my updates for Brands Hatch, Montjuic and Syracuse.

Here are some fixes for original tracks from Papyrus. I had posted some of this fixes before somewhere here. It is just improvements to AI speed through particular corners or attempts to improve overtakes.

Kyalami
AI was always slow for me through Barbeque Bend and Sunset Bend. I made some fixes for this turns.
Attached File  Kyalami_AI.zip   38.94K   94 downloads

Monaco (Monacane)
I don't use original Monaco anymore. Like Pete I had replaced it with Monacane and renamed to Monaco.
Increased AI speeds at Mirabeu - Virage de la Gare - Portier. Some adjustments to Gazometere hairpin. Additional passing flags to improve overtakes.
16.01.2016 I fixed AI behavior at chicane. Now AI cars are fast. But 1969 cars are wider so AI still have crashes there. Additionaly I made apply all same fixes to original Monaco track.

Monza
I forgot if changed speeds there :think:  But if I did then it was at Lesmo 2. Also I increased number of passing flags on straights.
Attached File  Monza_AI.zip   67.42K   97 downloads

Nurburgring
It seems like original lps were gathered from several pieces. And racing line had bad transitions between this pieces. I smoothed them and placed additional passing flags.

Silverstone
I tried to increase AI speeds through Maggots, Chapel and Abbey. AI don't like such high speed corners with small radius.
Attached File  Silver_AI.zip   212.82K   22 downloads

Zandvoort
AI always was ridiculously slow through Pulleveld corner.
30.08.2015 Improvements to section Gerlachbocht-Hugenholtzbocht
