v0.85G1 :
Finally the PID is properly integrated.

See the update for the MANY fixes that come with this version (which were all fixed in a rush, so i might have created new ones).
Otherwise, this is by far my best attempt so far at making those idiots act like drivers. Not racers yet, but at least they can handle a few corners together and, with the corner inputs, they can be atrociously fast.

The users of real vintage (we're talking 50s here, oil and dust) can finally create ai cars that can drift, power exit and take hairpins like ****ing champs.

The GT3s should shine, i only tested a bunch of them on the excellent @parilla 's hockenheim fastlane, and the Darche 992 was absolutly nailing it, drifting non stop and turning in at 1.37 (which i have no idea if it's a good pace).

The Kunos were a little behind, but still 2-3 seconds faster than the car#0 (who gets no inputs. If you're new here, the player's car is a test subject to validate tweaks).

I had to abandon my lovely 60s pack to manage a "works for all" setting, but i'll be back on them next week, probably with new profiles and dedicated behaviors.

read the following rambles and the discussion thread for some tips on getting used to the app. It's a nightmare - but it works, i swear.

By the way, i included many characters with the app, some of them come from previous versions and would probably be terrible with the newer versions of the app. Pick the ones you wanna try, if not working, pick another one etc... It's all testings and fixing regular issues atm.

On the previous episodes of Ai whisp :

v0.84f1 :
Broke a few things when transferring the PID.

As a few of you noticed, the starts and first laps are a little weird - slow, safe and boring.


I'm gonna say it was on purpose (it was not), for the most prone of you that immediatly test a worst case scenarios on their first try (you know who you are). The cars flipping on 1st corner was definitly a hint (thanks to Damgam who reported almost immediatly).

I'm gonna fix it and update it in a couple of code lines, along the Vintage drift setting (finally) that allows you to drive along AI drifty cars with the same amount of grip that you have. That'll be for another looooong convo about how you cannot drive a 50s roadster if you have tons of grip, a solution to boost AI never satisfied me.

I'm also increasing the overtaking abilities, it's gonna be pretty much reliable on next update.


Most of the data to use the app are on this overview page, in the discussion thread and the basics are in the manual that is in the app folder. Primarily for slow and vintage cars, blablabla, you know the drill.



Meanwhile, for this version :

Here are the fixes :

V0.85F1 :
-Fixed the "attack on straights" behavior that got completely broken in previous updates
-increased the sensibility for corner attacks/brake delaying. Might be a little brutal if you tweaked the app with previous versions.
-increased the link between attack on straights/attackbefore corners/diving : the ais should position themselves properly before a corner now.
-decreased the side by side inputs safeties. Despise being very safe, reliable and fun to watch, they were not that fun to race .
-decreased the sidelines inputs limiter. Because a wheel in the grass is always better for exits.

+ little add from 0.85F1b :
-the Traffic jam is updated, should work better and faster. Makes the AI runs a train on traffic jams, way faster than having the AIs stroking in the middle, and efficient for tracks with a hairpin on first corners.

If F1s/Modern users see a drastic spike in crashes and unwanted behaviors, i can also provide the previous version (with all the safeties) updated with proper attack on straight behavior.

The new overtake behavior is not fully implemented nor designed for fast cars.

The "cautious in hairpins" is an extra safety for hard hairpins (like Hockenheim) but can be switched off for slower tracks and cars.

You can use the alternatice one for a middle caution setting on hairpins.

You'll find a bunch of already tweaked cars and tracks to test the app in the discussion thread. I hope the community will post a few others, both to create new characters and to explore possibilities with the corner inputs and behaviors.


I suggest you bookmark the app and follow the discussion thread for little hotfixes. there are always little issues and i will, when a global update is unnecessary, post the hotfixes there.

Until next bug, catch ya.

Thanks to froik, alberto, timeless and kram for the reports.



Old versions and resources:


There's a hot fix (v0.85C) in the discussion thread, just little adjusts and a way to make the new overtake system work on anything faster than a fiat 500.

v0.85 :

Fixed the save issues
Fixed the compatibility issues with previous aiwhisp version
Cleaned the behaviors
Added a "apply character to all cars" button for faster edits on same class cars
Deprecated some WIP logics to the unreliable section
Updated and automated some of the attack behaviors

Added the new Overtake behavior : this one is super tricky and mostly useful for slow cars at the moment, but it has a huge influence on final pace while racing, since it WILL force the gaspedal on every opportunity (mostly between corners). Works on some cars, not on others, test and see. This is gonna replace the Elasticaution as it is way more reliable and way more powerful, especially on the positioning of the AI (it's using the PID from Edd i was talking about in my previous update).

tips for powerful modern cars : either use the --AI Whispere0.8-- Character to start without any inputs tweak or use the --SAFEMODERN BASE-- one.

For everything else, the DEFAULT should be fine, although super safe and not very fast (still faster than regular AI anyway).

For Vintage users, your AIs should achieve a 2 to 3 seconds gain in pace with proper settings, sometimes more. You can switch to the AI VANILLA Character to compare the gains.

Here's a small hint helper for the corner inputs tweakers

Cars that absolutly deliver with the app : all GTC60 and TCL Bazza's packs, Clio Cup, Darche 992 GT3, Ford 34 Legends, 1959 Chevrolet Corvette C1, 1952 Hudson hornet (for the matter, anything 50s gets a huge improvment), Toyota AE86, GT3s from Kunos need specific tweaks but work fine...

You'll find some experiments in the character selection. Note that i'm using my own fastlanes and settings for each track, so they might be off on your track's version, but it's probably just a matter of little adjustments.


I wouldn't start working on something like the Nord right now, especially without a very good fastlane, but on anything with a 1-2 mins lap time the app is pretty self demonstrating on its abilities.

The racing between AIs should really shine with tweaked cars, with a lot of overtakings. the attack behaviors are important to tweak as well, as they will usually get the car at the back slightly faster - allowing for packs all along the race, without everyone drifting in a boring solo experience.

i'll let you petrolheads find your way into the app for modern cars and formula ones, i will on my end start introducing the drifting behaviors and other missing stuffs for vintage. Reach the discussion thread if you encounter any issue or if you're struggling with improving the AI - always mention CSP version and car/track combo so i can replicate your issues and find a quick fix.
