There was a time where a big goal was to make an intelligent A.I in games, I really wonder when (or why?) it completely stopped being a focus, I mean, Unreal 1 or Command & Conquer Renegade has so much more competent AI compared to a vast, VAST majority of today's games.
AI in the Ghost Recon/Rainbow Six games has never been worth a shit. The only time it was semi decent was when you actually planned on the map their entire route and hold/go orders. Remember the enemy AI in Rogue Spear, or the original Ghost Recon? It was pretty bland
But then you go Hey, that was 1999, why is it still like that
I want AI that dynamically learns from players and emulates human action, while remaining distinct (Some more aggressive/suicidal than others, etc)

Games have generally become more cinematic and scripted, and therefore require less intelligent AI.
I've noticed there hasn't been any real advances in AI in years, they still all seem dumb as hell.
Tru day, though wouldn't dynamic learning require a lot of processing power for a significant number of enemies?

lets say 2 bots on both teams in a game like... UT99 (to keep it simple) they learn dynamically to what the players do.
If a path leads to easier kills, they take it.
If a gun leads to easier kills, they use it.
If a tactic/movement leads to easier kills, they use it.
Aim matches humans as well.
Once we have a certain level of processing power in computers this will be EASILY done, with the right scripting, but right now it'll be very damn hard. That being said, a bot that knows how each human acts and develops their own "Personality" would be a very powerful team mate. Chat messages will work like cleverbot.
is bioshock infinite supposed to have revolutionary AI or something? i haven't been keeping up with it.
Im just curious but I wanna ask this question to you guys:
Which game(s) did have the best AI in it?

Arma 2 had some pretty decent AI behaviour
[QUOTE=Spot of Tea;39775746]Arma 2 had some pretty decent AI behaviour[/QUOTE]
You serious? I was on warfare, built a base with an entrance wide open and the ai just ran in circles.
Also had it on co-op when theres lots of enemy fire and they just run right into it.

F.E.A.R had some neat AI because the enemy would dynamically take cover (and by that I mean actually jump through windows to hide in a room), call for backup, try to flank you, etc.
Half Life was amazing for its time, because enemies didn't just attack you and were trying to stay in group, not to mention when they got hurt too much they ran away to hide instead of shoot at you until you or them would drop dead.
Resident Evil 4 had a rather good AI in hard mode too, because in open environments enemies would flank you, swarm you from all sides, put up ladders to access windows if you chose to hide on upper floors, etc.
Also Dead to Spies. Now THIS is hard as fuck game that proves an AI that is too intelligent will just ruin your experience. The AI was so precise and determined the slightest bit of mistake would blow your cover. Kill an enemy with any weapon that is not fiber wire ? Don't even think about taking his uniform as disguise, the blood on it will get you spotted in no time. Stole an officer uniform ? Good for you, but don't go near other officers, because officers know each other and they will understand you're not supposed to be here the instant they see your face. The list goes on.

with some mods, maybe
[QUOTE=milktree;39775716]is bioshock infinite supposed to have revolutionary AI or something? i haven't been keeping up with it.[/QUOTE]
yeah, just like how Halo: Combat Evolved had revolutionary AI
bioshock infinite is full of scripted sequences with minor dynamic interactions between them ( a lot like Half Life 2's AI in fact, but much more developed)
the ai itself isnt really that revolutionary at all, only more fleshed out i suppose

sorry man but FEAR was pretty scripted. It was very well scripted and seemed quite dynamic but really it wasn't.
[editline]3rd March 2013[/editline]
the halo games have had pretty consistent good AI. I really can't think of many other games that do. Maybe Syndicate?
But this video doesn't respresent the AI in this game at all.... Its a just a bug.
The AI is actually very intelligent- when you mark targets for them to kill they get into position and line up their shots without being seen quickly. They're not thick skulled in combat, just as the enemy AI isn't as they use and switch from cover to cover, as well as flanking you constantly.
The biggest flaw with the game is how the game sometimes forces you to use a single tactic to proceed- e.g in one mission there are loads of enemies and you need to use a great big box that can walk and shoots missiles and grenades to help you or else you're fucked. Its annoying because it never runs out of ammo, has no cooldown between shots, its invincible and auto acquires targets when you designate in their general direction. It sucked out the challenge so I tried to use it only a bit.
In one stealth mission at an airport you're throttled into waiting for planes to fly overheard to muffle gunshots and even if you wipe out all the enemies in a group but one (say in a group of 7) if he detects you and raises his rifle before you kill him you automatically lose, even if he hasn't fired a shot.
That one mod for BIA road to hill 30 still has the best ai i've encountered thus far.

could also have been earned in blood, my memory's not what it used to be.

Ghost Recon had a pretty cool feature where if you decided to just command troops instead of actively play as one, when you give a cautious move order they'll actually assign a point man in a squad and have him advance first and once he makes sure its clear the rest would catch up. They would do this over and over, it was very slow but they got to their destination alive. They even used hand signals.
EDIT: Ghost Recon 1 of course, not this new garbage.
I remember the AI in HL2 being pretty awesome. Combine soldiers, whilst pathetically weak, had a huge amount of tactics built into them. They'd form squads and flank whilst you were taking cover and they knew when and where to use grenades.
[QUOTE=Wiggles;39775633]Games have generally become more cinematic and scripted, and therefore require less intelligent AI.[/QUOTE]
In a way, you could thus say that modern AI enemies, and even allies, are like actors, with how scripted and popbook they tend to be.
And in cases like Aliens: Colonial Marines, they're like dyslexic, retarded actors.
Older games were less linear as well, so you couldn't have shit pathfinding.
I remember while playing Spec Ops: The Line, I was in a difficult firefight late in the campaign. Up until then, the AI had never been much to write home about, you can point targets out to your squadmates and they'll shoot them, otherwise they'll mostly stay out of the way and pick off stragglers. Anyway, I started to move around the side of the enemy to flank, and my character radio'd my AI partner to keep the enemies attention so I could flank.
Impressed the balls out of me. Sure it's cool when you have enemies that flank you, but I think it's awesome when the game realizes what you're doing and adapts.

The maps were also less cluttered

We already have this in games. The AI might not copy a human player, but they adapt to the environment they exist in to survive just like human player.

99% sure that's how it's done in UT99. It's simple minimax, maximizing the utility of the next action and reducing the losses based on data gathered.

[QUOTE=Dirty_Ape;39777320]Older games were less linear as well, so you couldn't have shit pathfinding.[/QUOTE]
that's arguable.
ARMA 2 AI alternates between pants-on-head retarded and pretty smart.
For example, I was once playing an SP mission and sniping at some infantry with an M107. Then, I hear a helicopter. The helicopter proceeds to circle over the forest I'm in, and armored cars and Vodniks begin to approach (about 3). They then sit outside of the forest while the heli circles leaving me pinned in a forest
Other times, I've had squads of infantry go uphill from me without me notice and fire down at me while I'm still being attacked from the front. Some of the civilian AI is neat too, during this mission that I'm always replaying(skirmish generator) there are civilians that will drive and wander around in towns- when the shooting starts they all move away quickly.
Other times the dumbfucks will just sit there or stare at me. Or walk in circles. Or get stuck on doors.
One time a guy in a truck sat in the driver seat staring at me, when he could have easily moved to the gun and fucked me up. But he just sat there. Didn't even try to run me over

Crysis and Crysis Warhead have some really high quality AI when you go onto Delta difficulty. Sometimes they bug out and do something incredibly stupid (like following you into the water and then drowning), but they're overall very intelligent. They'll flank you in urban environments, and if you go invisible, they'll discover you if you cross one of their laser pointers.
The Halo series also has some pretty effective AI, especially on Legendary difficulty. They aren't suicidal, and will fight very conservatively until they know they can swarm and kill you.

I played a bit of RSV2 and the AI is literally exactly the same as in Ghost Recon 1.
