'AI' you have actually noticed in game.

With all of this talk by developers of their revolutionary 'AI' in games, I never even seem to notice. It still seems like everything is on a path, doing a certain set of objectives.

Take UT2004 for example. The boughts just run around the map in perfect straight lines, know exactly where you are and shoot you in the face.

All racing games have had booty AI.

Half Life 2 was no exception, the AI was just dead to me.

Halo the enemies just seem to run around, with no order, no intelligence.

Half Life 1 had some cool things like taking cover, throwing nades at you, working together, but that was the extent of it.

The best AI I have seen is in Perfect Dark, both multi and single. In multi, me and three of my friends camped in a room set up with laptop guns, and we were armed with AR rifles. We played against 1 dark bot in the complex (We were in the room where there is on ramp in that has a hole to drop down below, and it overlooks the big room with the double ramps). The bought came in a couple times, and was slaughtered. Then the bot didn't enter, it went to a spot and hid there. We decided we needed to lure the bot (or rather 'simulant') so we set out one person as bait. The person would run with their gun's ablazing into the room with the bot, and run out as quickly as possible (without dying of course) and run back to our room. The first time the bot took our bait and died, but the next time the bot didn't run after us. It was really creepy.

Also the single player seemed to have good AI, with guys taking cover, getting reinforcements, etc. The best is on the submarine level is to look through the glass in one of the doors, and to snipe the guy in the other room. Another person runs over to the dead body and says numerous different phrases like: "My best friend" or "I never liked him anyways" or "Nooooooooo". Just subtle touches like that (like in goldeneye when you shoot a guy in the butt and he jumps and grabs it) really engrosses you in the game. Good AI can do that as well.
 
To add on to the AI quotes, today while playing Halo 2 for a bit, I borrowed a sniper rifle from one of the marines that had been tailing me, and he said "See? He wanted my gun."

I thought that was pretty good.
 
Whenever I die in Psi-Ops, enemy soldiers run up to my dead body and kick it. Yes, veeery advanced.

What level are you playing on? Pansy?

Edit: And yeah, that's NOT AI, that's a random scripted event.

I was adding on to that, as I said.

For deathmatch I play one on one on all the maps in a rotation against the second to the hardest setting. They are usually very retarded.

Albatross is my favorite level.
 
the ai in halo is awesome. halo 2 especially. have "unit" (or race) behaves entirely different in battle, either by charging head first, flanking or being "stupid". hell, the flood in halo 2 are particularly cool IMO because they do hit and run tactics.
 
To add to the funny Halo 2 AI moments, I was playing Co-Op with my brother and when we ran into the Sergent again in the first stage, I told my brother just to watch him kill everything since he was invincible. After a couple of seconds of watching him he suddenly yells out "Stop watching me and start shooting!" That made me crack up.

i swapped out my smg for a marines sniper rifle and he said (sware to god), "this reminds me of the time i got herpes." :lol i was dying!
 
On a more serious note though, I think it's hard to know if it's AI or not. The enemy being clever and strategic could just be a coincidence/accident (because it recognises 20 % of your behaviour, acts according to that and gets lucky), and how many times do we know if a certain behaviour is heavily scripted or not (yes, I realize AI is scripted behaviour in a sense, but you have to draw the line somewhere)? I hope AI really improves next gen (if it's related to hardware limitations more than programming limitations, I dunno)...because that's one area where games today are definitely lacking.
 
:lol

DarkSim with the speedsim properties gave me nightmares :( I'd have him dressed as Mr.Blonde. I'm serious, nightmares.

That is why you NEVER mix speedsim with darksim. It freaks me out just thinking about it. Though a dark venge sim may be worse.
 
The only AI I realy noticed in a game was in FarCry. I had to actually tactic everyone of my decision insteed of runing in the pack guns ablazing.
 
Yeah, Perfect Dark's sims are awesome. That pacifist bastard making me dizzy the entire time I played him, plus it carries over when you die.

I remember noticing JFG's AI, each colour of ant acted differently. That's probably why I noticed actually.
 
soldiers in MGS3? they seem pretty adept at finding you once you make a noise or something...

..But once they're in a melee attack, they're dumb as bricks: I'm still pretty early in the game, I was just meeting Eva for the first time today,
and I killed all those ocelot operatives that greet us in the morning
with the knife, I'd just come up to them from random-ish direction to avoid their barrage of bullets that they can't seem to be able to aim anyway and I'd just slit their throats. Gee guys, ever thought about MOVING to not get grabbed and viciousely killed so easely?
 
and how many times do we know if a certain behaviour is heavily scripted or not (yes, I realize AI is scripted behaviour in a sense, but you have to draw the line somewhere)?

There is no part of AI that isn't scripted in some way, though. I'm no expert on the subject, but AI is a really hard thing to judge on a scale, I've always thought. "Better" AI can only really come from narrowly defining specific situations, and I highly doubt there will be any big changes in AI this generation because of that.

I certainly notice RE4's, but I'm not sure if it's technically up to snuff with other games.

I ducked into a building, and the dude followed me thru the window and another opened the door. I was scared as hell.
 
well as next gen games become more complex and hardwiring AI for diffferent situations starts to become an impossibility due to the sheer number of situations possible (I'm taking next gen stuff like global physics engines into account here), they'll HAVE to develop "learning" AI sooner or later to get out of the endless ai development pit.

Even if they use learning AI only during the development to let it grow on it's own instead of wasting time to develop it, and then just implement the fixed final result into the game, I feel that'd be an improvement...
 
For anyone (claiming to be) not impressed with the Halo 2 AI: Go to one of the Warthog levels, hop in the passenger seat, sit back and let the AI take over the driving and gunning functions. It's a pretty interesting show. The ability of the driving AI in particular to navigate complex terrain is really impressive.

Yeah, I realize that all AI is scripted in some way...but still, how much is actually "intelligence" when your enemy has like two choices to go up against you, and both are them are like running into certain death if the player strays from the "assumed" path of choices? What I'm saying is, even if the enemy is "intelligent" enough to make a decision, those decisions make it as smart as a brick in more than one situation.

Easily the weakest example of the Halo 2 AI. Every time I got in the gunner seat, the AI acted like an elderly asian woman driver.

Tokyo Xtreme Racer has decent AI in that rival drivers act human and have distinct driving styles.

oh yeah, thats true. some of the teams youd race against were out for blood, while others were literally pussies that would rather let off the gas then battle for the lead.
 
I think Halo 2 is one of the few where it's obviously in place to any effective level. Sure as shit smarter than Half-Life 2. Some games also have much better scripting, where it's far more seamless or surprising. In RE4 they mostly just amble right at you (though sometimes it's a fast amble) but the way they'll come in a building and such is really cool.
 
Both Halos have GREAT AI imo.

cant think of any other games at the moment but since Im Currently playing RE4 i must say...the AI in this game is actually GOOD. im being suprised every now and then by something that the AI in the game will do (either that or im just so use to the AI in previous REs that this just stands out).....kudos to capcom.

peace

Yes, it is. It's situational awareness. That the NPC's know enough about that is happening around them to react the way they do is the very definition of AI. If they are stared at, shot at, spot enemies, have allies near, have you fighting with them, see you do an amazing shot, etc they all react accordingly. It's AI, and on the surface it's simple but in agregate it's very complex, and pretty damn impressive.
 
GhaleonEB said:
What the fuck.

Well, I played all the way through Halo 1 (not all the way through Halo 2) on the second to hardest difficulty, and this is what I noticed. Granted I played both In Co-op, but seriously, the enemies never seemed smart. They sure had a lot more movement options than said other games, it just didn't seem 'smart'.
 
If you didn't notice Halo 2's AI you were either not paying enough attention or playing on pussy-mode. Play it on Legendary and tell me the AI's not noticeable. Yes, the snipers are kind of cheesy, but the reactions of the other enemies in several situations is damned impressive. I can remember hopping out of my Warthog into a building to duck some Elites that were trailing me. I pocked my helmeted head out of the door only to see that an Elite had jumped into the gunner's seat and started blasting my ass. There were numerable occasions where enemies intelligently flanked my ass into a corner and wasted me. And try to tell me a Legendary-level Elite with a sword tracking towards your ass isn't intimidating.

Half Life 2's AI was, to me, dissapointing. But I suppose that's due in part to how damn impressive the original grunts from HL1 were. That's the first time I ever felt really stalked by an enemy in a FPS.

Maybe you had an elderly asian woman on your squad. My guys zip around like nobody's business.

I find that spacial navigation in complex 3D environments is one of the most common weak spots in game AI. Halo's is just awesome in that respect.

Culdcept. CPU opponents will tear you a new one if you let them. Never underestimate them.

Oh fuck me I swear to God that game cheats. I have never EVER been as angry at a videogame as I've been at culdcept. Throwing the controllr against the wall, storming off cursing, etc etc. It's great though :D

I'll be so up for an entire match, and then LITERALLY the ONLY sequence of events that could POSSIBLY lead to me losing happens, one after the other. The enemy AI always used the most insane stat modification trickery I've ever seen in my life to ensure that he wins the battle by 5 or 10 HP. Then next turn I roll exactly what I need to to LAND ON THE COMPLETELY LEVELED UP SPACE THAT HE STOLE FROM ME. I'm not worried yet though, because I should win the battle. But NOOOO more chicanery is afoot that again allows him to win by the bare minimum HP. Repeat this two more times in quick succession and my 4000+ total magic lead is reduced to nothing in mere minutes, after an hour long match. Mother fuckers. I'm getting angry just thinking about it. The post-game graphs are absolutely ludicrous.

I wanna play :)
 
I think a lot of the confusion/debate over what is AI comes from the fact that there is no true AI in video games yet. We use the term, and it's not like it's morally wrong to use it :p, but it's a misnomer. All actions by NPCs in video games are just scripted. What we call "good AI" is just a more specific script than that of other games.

Obviously, none of this matters as far as the topic question is concerned. In Age of Kings, I've played against some fan-made AI settings that really blew my mind. I wish I remember what the name of the script is.

Although perhaps not the smartest AI around, those enemy cars in Burnout 3 are just plain angry.
Burnout 3 has one of the worst rubber band AI I've ever witnessed in a videogame. Making 95% of a race perfectly while boosting all the time and having the AI right on my tail the whole time so they take you over on the only mistake you make is NOT my definition of fun. It's my definition of me smashing a controller on a wall (first time in my life I ever did that)

Well in Halo 2, all enemy characters have sensory inputs and react accordingly to what happens around them. That is what I would call true AI. None of their behaviour is scripted, and that is the reason why every battle pans out so differently in Halo. They see an enemy and they make the decision to fight/run/take cover, it's not scripted.

On higher difficulty levels, the AI is very impressive.

While I'm not defending rubberband AI here, if you play the entire race boosting whenever you have it, you're not going to accomplish much. Only boost when you're not in first, or if you hit a wall. Otherwise just keep your speed up high.
