The AI thread

Not quite that drastic, more like gentle weaves. I believe the F40 in the video I posted from Prologue, is doing just that, down the straight :)
have to watch the F40 again to confirm

Funny enough some F1 driver commented that Hamilton must have thought he was playing a Playstation game :dopey:

I would find it hugely entertaining if the AI, varyingly, employed similar tactics. Perhaps they may just end up with a personality of their own (per "driver")...

I wrote this back in May of 2006.

I was wondering how many parameters you could actually quantify in regards to categorizing what makes a racecar driver. This is what I came up with:

Skill level
Intelligence/Learning/Observing/Adapting
Tactics/Tricks
Endurance/Strength
Control/Courage
Patience
Daring/Chance taking
Intuition/Luck/Spider senses :D

That was about all I could sort out.

An intelligent driver could adjust his driving based on what you were doing, and improve his skill level faster as the season progressed.

A tactical driver would have a better idea of how to deal with cars in a group ahead of him, rather than dealing with one at a time, like a chess game, and be better able to perform a daring pass.

A stronger driver wouldn't tire during long races, and his level of skill slip.

A courageous driver wouldn't be rattled if you nearly caused a wreck and continue to challenge you, while a more timid one would back off.

If you were reckless, a patient driver would wait for you to make a mistake rather than challenge you constantly.

A daring driver would risk a collision if he was following you, it was coming down to the wire and one of the last few turns were coming up.

An intuitive driver would have a sense of what was going on ahead in the pack, perhaps without seeing anything of it.

I suppose the essential parameters would be Skill level, Intelligence and Endurance, and that would be sufficient to define a modern race driver, and you could derive a lot of personality traits from just those three.

Lo and behold, in Forza 2 and 3, they have named drivers with specific personality traits.

This is very definitely the style of bot programming I want to see in Gran Turismo from now on. And yes, I want a career mode with bots that have names and go through the season with me, progressing, growing, learning, and tracking the stats of them as well.
 
Well for sure the AI drivers in Prologue drive differently, even if they don't have names. I can sense varying styles in there. Maybe more to do with the driving effort level as per B-Spec in GT4. ie some AI drivers use effort level 2-3, whereas a few of the faster ones use 4-5, hence why some go off track etc
 
Yep! The Le Mans video shown a lot of improvements and I think this is the most precious.
They are aggressive, the AI train is no more a train!
 
AI and three a breast at le mans and a slammin it down the inside of each other and the player which is great
 
Had a good long session with GTR Evolution and one thing I turned on today, was AI name tags, while racing

I'm hoping GT5 includes this option ontop the cars like it currently does with online races in Prologue, with human players.
Having the names displayed above the AI cars, adds a lot of subjective personality to the AI drivers

Seeing as GT5 AI have names now, and most probably personality types/driving styles and emotion. This would be a nice option to have 👍

Uh, that was already in GT5P, so it wouldn't be that much of a surprise.

Snowgt is mistaken. It does NOT exist in GT5P offline with AI.

Sorry, you're right, it's not available offline. Although it makes no sense to me with AI drivers to see ficticious names above the cars. What on earth would you need that for? It's another car racing you, so try to overtake it. It most likely won't matter which AI controlled car is racing you, because in all likelihood they won't have different "personalities".

I would find it distracting actually.

For the same reason GTR Evolution has it!
You do have championships with each driver having a name and points on offer each race, just like in real life. And each AI does drive differently, not every AI drives at the same speed.
It will be really handy for the longer races when you start to lap some drivers.

I don't find it distracting at all. It's not that easy to tell which is which car just by the liveries, and it works fine online with human drivers

FYI Kaz did say on video, that once the core AI is in, they will start to add "emotion"
 
If that does end up being in, I hope it can be toggled off. Wouldn't be distracting, just abit silly looking to me to see cars racing with names above them. Only good effect it would serve for me is to see who I'm lapping. I'd rather have a scrolling telemetry with all the drivers names.
 
AI has some rather weird and exotic names - and 2 cars with the same name..... :)

Kaden, Karnari, Brayan, Melvin, Braiden, Kadyn, Brayan -- they all rhyme!

Some good basic AI on display here at the start

B-Spec should form the foundation of GT5's general AI. As you know in GT4's B-Spec didn't work well, and so it showed in GT4's general AI. Tending to bump the car infront instead of overtaking cleanly

A live demo shows it in action as a Ferrari 458 Italia is put through its paces around the Nurburgring's Grand Prix circuit. It looks gorgeous, as you'd expect, but there's another revelation in the action. At the player's command, the Ferrari attacking outside the first corner and then holding its line for the inside of the next as it pulls an aggressive – and impressive – overtake on a Citroen GT car.

The next opponent is a Gallardo, which the Ferrari hangs on the tail of looking for gaps at each turn. As the first corner approaches again, it dives for the inside but the Gallardo blocks him off. At this the driver's mental status takes a dip – as indicated by an onscreen bar – and as it continues to push it makes more and more mistakes, overshooting apexes and letting the rear-end slip out a little too far as it falls into the clutches of the Citroen behind it. It's dynamic behaviour that suggests that Gran Turismo's A.I could, at long last, have been brought up to scratch.

I am very impressed with what i have seen from Gamescon reguarding AI.

They are very agressive, and will finally race each other seriously for victory, They no longer race like a amature track day.(always taking the outside line, But never diving in the inside, I'm looking at you prologue.)

They are smart and will avoid alot of accidents in close range.

They are fast, And some(majority) of the players have not been able to keep up with them.

They have personalities, Which is something i liked in forza 3,

All in all, The AI has really been overhauled from prologue.

Also in one video, An AI driver in the M5 (Sullivan) got side ways in a corner by him self Very impressive. Excellent work PD, You have seriously done your home.

Racing offline should be a blast!
 
You can see it in this vid - the Black/red Motul is rather aggressive, nudges the player and then wobbles down the track and nudges another AI car :)

Noticed they're quick through chicanes. In a lot of games, AI is really slow through them


And watch the AI BMW oversteer at the 2nd corner as it battles the Muira

Straight from IGN regarding the "new overhauled AI"

This is what i always wanted to hear from a GT preview.

Outstanding job polyphony 👍
 
This sort of AI is no surprise to me, they did identify it as one of the main areas of improvement they were focusing on since GT4.

They do have a more human aspect to them, and aren't complete noobs at overtaking (Which puts B-spec mode in good stead - No getting stuck behind the other cars for the entire race even if you're capable of 5+ second faster laps), which has been evident in videos for a while now.

The speed of the AI is no surprise either. I mean, look at S10 in GT5:P. The lead cars (Usually the Tuned Corvettes, Amuse S2000 GT1s, Tuned Ford GTs) were running laps just over the 2 minute mark at Suzuka, which means you have to have a fairly good degree of skill and consistency just to keep up with them, never mind pass them.
 
THat same video shows an Audi TT ramming in at full blast, and keeps blasting despite being blocked by a spinning zonda.

Mixed Feelings, but I've been playing GT4 recently (where the AI uses the SAME braking points wether in 1st or 5th, they ram into you screw your tires up and they act like its only them on track) and its a HUGE step up, now if they could only fix the blast bots who just plow through you like freight trains.
 
They also need to make it so you don't get penalised for every accident regardless of whos at fault,

It would be interesting to know what kind of mechanical damage will effect AI cars, like for a 24hr race, will they drive around perfectly for 24hr as basically markers for you to continually pass or will they be in and out of the pits with problems other than new tires and fuel, becasue a cars endurance is the only thing equal to a drivers endurance in a 24hr race.?

From 1:30 on the AI looks fairly sharp and looks like it wants to get past as opposed to sitting back and accepting its position:tup:

DAMN! Look at that move at 1:37!!!!! THAT is what I like to see from AI. This game is going to be AWESOME.
 
Does that car come with inboard toilet roll dispenser.
For squeaky bum moments.
