Half-Life 2 - Advanced AI in Action

[alpha19602]

OH MY GOD HE HAS A JAR

[escator29]

The "AI" has been "Trolled" hahhaa xD

[TheSharpTHOfLulz]

Don't mind me, I'm just a happy jar of mayonnaise.

[CarlMinez]

I dont know what you are talking about, but I think Half Life 2 has been critically praised for its intelligent AI.

[agenerichuman]

@CarlMinez it has received praise for its AI by people who confuse the scripted sequences for AI and by people who didnt played the original.

[CarlMinez]

@agenerichuman

So it stands between listening to the consensus of like all game critics from Metacritic and a few YouTube comments. And my own experience points me to the critics perspective.

What would you conclude?

[agenerichuman]

@CarlMinez see. i dont rely on opinions of others. i rely on my knowledge of computers, programming, and "AI" (i put it in quote since theres no way this stuff passes the Turing Test).

critics are just gamers. they are often ignorant of the technical side of games (much like the average gamer).

if you watch the video, you can do this in game. its not a video trick. the AI is deeply flawed. the great thing about a claim is you can actually test it yourself. we arent lying.

[agenerichuman]

@CarlMinez additionally, people mistake heavily scripted events for AI. take the enemies drop explosive barrels into the water you were swimming in. pure scripting. the enemy cant "think" to use this tactic at will, which is why you never see it except for a few places.

wanna see good AI? play FEAR and play Half Life 1. the latter may not have sophisticated duck & cover mechanics, but the soldiers actually use tactics and can outmaneuver you if you arent careful.

metal gear in a nutshell

[1337MrSam]

technology

[Eddman368]

that combine must've been louis in disguise, he could never bring himself to shoot a bottle of pills.

[morganleer]

@Eddman368 Or maybe Louis joined the Combine :o

[ivyssauro123]

auhuahauhaua this video is fucking hilarius!!!!!!!!

[PheonyxImperius]

Spawn a bunch of them on a map in GMod and you'll see how brilliant they are. The map holds them back.

[CrazyCinnimon]

hold bottle of pills in front of you = invisible

[FrozenSparky]

this has been fixed... atleast on orange box HL2

[joseaca]

@FrozenSparky i just got HL2, its the exact same thing

[FrozenSparky]

@joseaca you got the normal HL2 not the Orange Box version.

[joseaca]

@FrozenSparky if you say so...

dont get why there should be different version though, specially considering i got the game on steam so it should be updated

[FrozenSparky]

@joseaca dont you get it? you bought just half life 2. i bought orange box which has different half life 2 engine

[joseaca]

@FrozenSparky are you stupid?

they both use the same engine, in fact, im checking my friends account, he got the orange box, and its the same freaking game

i think you are mistaking half-life 2 with its episodes, which DID get engine and AI updates, specially Episode 2

[FrozenSparky]

@joseaca im not stupid. orange box hl2 has better graphics than the normal one. check it out

[joseaca]

@FrozenSparky its the exact same game, my friend got the orange box on steam, EXACT SAME GAME

[XenoSpyro]

@joseaca @FrozenSparky

HL2 has the same engine updates as the Episodes once the Orange Box came out, even if you buy it separate.

Only way to play classic Half-Life 2 is Original Xbox. Problem solved.

[joseaca]

@XenoSpyro first of all, im pretty sure many of the graphical effects of HL2EP2 are not in HL2, and second, we are actually arguing about if this is still possible in the game

[XenoSpyro]

@joseaca Name me one that isn't. Spawning and killing an Acidlion doesn't count.

If you wanna know if the AI view is still blockable by objects...couldn't you just go test it yourself?

[joseaca]

@XenoSpyro i DID test it myself, HL2 still has this problem

i got the game recently, the other guy keeps saying the orange box version of HL2 is different when it clearly isnt

im not talking about the episodes, i mean the original HL2 in its actual state

[XenoSpyro]

@joseaca then im on your side

Just tell anyone else that has doubts to just look at the options UI. If you have "enable multicore rendering" or any of the other new options, it's up to date :)

[ryder187mac]

@FrozenSparky It's the exact same game. You could be thinking of Half Life 1, which did get ported to the new Source engine and was called... Half Life Source.

[warnightify]

My mayonnaise is gonna protect me!

[byerscm]

wow valve fails at ai hell doom has better ai xd

[byerscm]

lol all you have to do is throw a greade and run to the dumster

[VanciTyCroNic]

lololololololololol thats hilarious

[WORSHIPxCHAOS]

Little do the gamers know HL2 is a third-person game!

[stkizza]

As long as i keep this jar of lard infront of my face.....he wont see me.

[Toastrrr]

Ravenous bug-blattter beast or traal anyone?

[VannahWilson]

Actually most of the AI in Half-Life 2 is pretty good. Obviously some of it's pretty bad, like for the squadmates, but overall most of the AI is good.

[AzfarGamers90]

That was some.......

.....

jarring moment..

[Inny1984]

The Jar is a spy

[SirZeldaKnight]

I watched this video before I played the game, so when I got to this part, I did the exact same thing, but with  a coffee cup instead of of the jar in this video. It had the exact same results. But I also didn't lure him front of the gun either. I just shot him dead with one of my own guns.

[kyleowsen]

I can't see you, you can't see me!

[j4ff4c3ks1]

I think that the gunner AI is programmed to stay still so that he wont leave the turret. If he would use normal AI, he would have come to you instead.

Also that part is merely for a short demonstration for grenades, as those are the first grenades the player gets. (unless you found the Lambda Cache in Route Kanal)

[gmodfan11]

I think that the metrocop gunner has different AI than the normal cop, I believe it goes by "If the player can't see me, i can't see the player" to make the method of hiding behind the cart and wheeling it forward work. So, when you cover him with the jar the cop cant see you, it is a flaw, but that flaw is, in a way, put there on purpose. Note how he stopped being stupid when he let go of the turret.

TL;DR: He cant see you if you cant see him, that is until he lets go of the gun.

[ynotdrol2]

@gmodfan11

He would be able to see Gordon Freeman if Gordon wasn't a pair of floating arms.

[djdjukic]

So the Metrocop is basically a baby. Freeman could have just covered his face.

"WHERE DID MISTER FREEMAN GO? HERE HE IS!"

[weeryan2008]

Isn't it just this specific AI programmed not to fire when an object is slightly in front of you? i.e. so that you can push that cart on the left up to him?

[Osman47]

he just didnt want to shoot his anabolic steroids. i would have done the same if i were a combine.

[smisch]

This is a stupid way to demonstrate "bad" AI. The game considers you in cover when your view is blocked, hence the AI does not fire. This is common in FPS, as the alternative is to have AI shooting at your exposed arm when you have no way of seeing that it is exposed. A few games ditch this convention, and it is extremely annoying when they do.

[corky064]

@smisch You're right, it's perfectly acceptable to baffle the AI by hiding behind a jar.

[MagFlare]

Sniper might be skilled in Jarate, but Gordon is the undisputed master of Ninjartsu: the art of jar-based stealth.

[KenisuIchojari]

Oh my God, he's using the Helman's! HE'S BRINGING OUT THE BEST!

[zerocks88]

Love the video descrition, this game was EXACTLY over four years old.

[BAPAKMUJUGA]

@786Puffy Yeah, but valve still updating it.

[786Puffy]

Everyone this game is 7 YEARS old. Stop complaining about outdated AI.

[AngelOnez]

This is why these games don't worth the money, just don't buy scrap like this it's like crysis, the only true ai i found was in unreal tournament 2003 when u set to learn from u.

[hurr48]

@AngelOnez do you just talk to sound smart, this video was uploaded 2 years ago and valve does this thing called patching

[Kingyoshi2010two]

@hurr48 I've tried this... Still not patched

[H3xx99]

I come bearing gifts!

[QuillOmega0]

It's hard to enslave good help these days.

[nopushbutton]

This is the videogame equivalent of a baby getting confused when you cover your face with your hands.

[DawnCaster]

"Don't mind me, I'm just a jar of mayo"

[synthburn]

Ahh the old mayo jar cloak

[harrylarry68]

Also do realize that the AI are not programmed to shoot the objects you hold but only you. I guess technically by holding out an object in front of you the AI gets confused and assumes the object is floating thus assuming the player doesn't exist. This is in 2004. They will make huge improvements in the next Half Life.

[dathwampeer]

@harrylarry68 They're making a new Halflife? Has anybody told Gabe?

[harrylarry68]

@dathwampeer Um Half Life 3. Do you really think the game series just ended with Half Life 2: episode 2? Honestly methinks you are just being a troll.

[harrylarry68]

The AI have issues that is fact but still this game is one of the best in my opinion. They better fix the AI in Half Life 3. In Half Life 2 they really weren't that dumb. I mean sure they went in single file and they always stood out in the open but still they stayed around corners and they moved towards objectives.

[ToneBacas]

maio. combine's greatest weakness

[Lionheart590]

so apparently the half life 2 AI runs off the principle of "i can't see you, therefore you can't see me"

[BloodHuman3]

@Lionheart590

You make it sound bad.

[EasyAlphabetPony]

Ahahaha

[ThePersonofComents]

The combine thought it would be a good idea if they started recruiting Ravenous Bugblatter Beasts of Traal.

[rokitiger]

realy "advenced" XD

[SladeForelly]

That officer is Luis, he will NEVER shoot at his pills ...

[HackVirusCheat]

if you cant see him he cant see you or w0t ? :)

[MISTAHHALOFAN]

lol'd so hard on this then in the end i was like "whuut? you kiddin' me?"

[sup3rt0aster]

hm. waddaya know, ostriches have the right idea.

[mbe102]

I love this game, I think the AI is fine for being some mechanically augmented human slaves. And half-life makes you want to feel like the hero, your the right man, in the wrong place. If you were the wrong man in the right place, your ass would be splattered all over City 17 when you got off the train haha. Funny video though. I remember them still shooting when I had use a barrel for Cover, and then sometimes the barrel would get shot out of my grasp.

[dunkace]

that was funny!!! XD

[IISilverSoul24II]

"I can't see them, they can't see me!"

[archivemind]

they're the combine, what'd you expect

[daEmoNicky]

AI checks if there is straight line between its eyes and players eyes. If there is it sees player. This approximation won't work in this case.

[DrWhiteGlint]

Unlike cones, you can rely on jars to protect you!

[TheNeekerirotta]

"If I can't see him, he can't see me!"

[Marcuzzorox]

stupid combine, LoL

[paisano612]

If only getting away from the cops was that easy. Just holding a bag of meth in my view while slowly backing away.

[1665kyle]

Lol you throw the mayo at him when he starts shooting you.

[upchuck42]

damn dude you got to find some ammo for you pistol!

[DonbeeFwz]

Well, it would be kinda difficult to program them to shoot at floating objects...

[Drillsergeant2]

This glitch reminds me of a similiar glitch in Amnesia.

[Isaiah6517]

Pills here.

[ViperStarFilms]

LAWLZ WIN

[viliussmproductions]

if i don't see you, you don't see me

[w00dpipe]

Gordon Freeman is Miracle Whip!

[Muad420]

Hah. I like how Gordon shakes his head in the end.

[nave4pres2]

I believe it's still the most advanced AI of source engine's next generation EP3. Just it has problems while using turret. You know how it works. If you can see it on the screen, he can see you too

[DrPepper42yes]

That cop is just like "HOLY SHIT HE JUST KEEPS POPPING OUT OF NOWHERE!

[792699]

Wth? O_O Does it really works? Wow

[jckiller32]

EPIC WIN

[hellhero28]

DAMN HOW DO I GET RID OF THAT GUARD?

AH HA! I'll CLEVERLY DISGUISE MYSELF AS A JAR OF SALAD DRESSING!

Years later Gordon publishes a book to recount Earth's emancipation:

CONDIMENTS OF WAR: How I Saved the World Using a Jar of Miracle Whip

Soon after he publishes a film :

LITTLE ROCKET MAN: The Story of the Gnome that Dreamed to be a Cosmonaut.

Which later became an award winning trilogy. The forth movie was never made leaving the plot-line at a cliffhanging stand still.

[byerscm]

@hellhero28 epic comment :D

[TheNewt24]

You seem oddly familiar....

RIGHT, I put you on my sandwhich earlier!

[DoctorIkeGE]

They seem to want your mayonaise that badly

[Shakduhn]

erm....... Sir, he's holding a jar of mayonnaise, WHAT DO WE DO? HOW DO WE COUNTER THAT BRILLIANT TACTIC???

[MetalSights]

AND THEY TOOK OVER THE EARTH IN 7 HOURS. HOW THE FUCK DOES THAT HAPPEN.

[Hurvl]

@MetalSights Because Breen sold us out, that's what happened. Anyway, I don't play shooters to be challenged and desperately trying to stay alive against all odds. I play them for the chance to kill as many enemies in as many ways possible, which is why I love the gravity gun and Smod. Most games have cheats or exploits and those games are only as challenging as you make them, so if you want to be challenged just don't use those tricks.

[dantetheangelofdeath]

@MetalSights Valve

[hamachiplayer]

@MetalSights

You know. Those CP are humans who joined the cause to just get a desent meal, (And they were also brainwashed,so they aren't really combines. You know what I mean. I'm not really sure, but this is how I got this.

[ibetrollinyall]

@MetalSights wellllllll thats the combine who took over the earth, not the civil protection service but thats a valid point

[Martinntoxx]

Here's Gordon Freeman! Oh,wait,nevermind,it's just a flying jar of mayonnaise. Move along.

[deathrain02]

This doesnt work with Portal 2 btw.

[Witto22]

@NeoSarinatan

You also typed same comment on /v/ 2 minutes ago...

[NeoSarinatan]

I did this with a human skull dropped from a dead barnacle once.

[Chri208v]

lol

[Metalix01]

peelz is there anything they cant do?

[Eximietate]

Someone SERIOUSLY needs to put "I've got a jar of dirt" to this video.

[starvedsanity]

that AI is still way better than Crysis 2.

[PlayMadness]

PREDINNER MAYONNAISE. IS GOOD FOR YOU.

[canertwo]

@PlayMadness

swedish CP! because one would never mistrusts predinner mayo !

[taitai907]

I'm laughing soooo hard at this.

[Toonlink003]

The Jars Contains A 1/4 Of Hair Of Chuck Norris. Is Not Fault Of Combine, He WAS AFRAID

[eivis13]

I bet it was Gmans piss in that jar

[ak47warhead]

Flag myself for a wrong video, anyway that jar probaly has some kind of deadly water in it, or should i say. Piss.

[ak47warhead]

Gordon freeman has unlock a new deadly shield called.

The Barrel of blindness

[Starioshka]

You could just hide behind your finger...

[gamerboy218]

the guards probably like damn how does this guy keep dissapearing?

[bogdan1231]

lol

BAM BAM BAM

unit down at 8-13

... pick up that can!

[SilenTScreaMxLC]

Firstly, the AI in this game is miles better than most.

...and that had nothing to do with the AI. It was just some stupid glitch.

[oopsIdidasuper]

@SilenTScreaMxLC It's a glitch in the AI.

[InSonicNia]

@SilenTScreaMxLC "I'm an overprotective fanboy who can't accept any shred of evidence that the game I like isn't perfect in every way, shape, and form and have to protect it vehemently since my opinion can be the only one that's ever right."

Get over yourself and accept that even good games have stupid errors like this.

[SilenTScreaMxLC]

@InSonicNia The same could be said for ANY game then in that case. Why go out of your way to highlight an stupid error in a game that deserves so much praise? Unneccessary negativity. Thats whats irritating.

[InSonicNia]

@SilenTScreaMxLC No one is disputing how good a game Half Life 2 is. It's got great reviews all around the board, and massive sales. But this isn't unnecessary negativity. It's pointing out an error in the game, while maybe poking a little bit of fun at it. Something that's actually massively IMPORTANT for the people who make the games. Besides, whats so irritating about people pointing out glitches for fun?

It's just fun, and we aren't hurting anything, and might help out in the process.

[MarsellusWallace]

@SilenTScreaMxLC Dude, there's something wrong in your head if you seriously view this video as some kind of "attack" on Half-Life 2. It's just a video demonstrating a glitch. Get over it.

[Isaiah6517]

This shy machines will never outsmart humans. Ever. The Terminator can suck it.

[uratoko]

he is still smarter than Bush

[TheFXGuy]

ROFL!  That's awesome!

[SuperGasbomb]

11 people shot his mayonnaise

(sorry, couldn't resist...)

loved it! only thing that could top that would be some of the l4d bot fails (see l4d2 daring bot rescue for an example XD)

[733t13]

They ought to make fun of this if Freeman's Mind ever actually goes into Half-Life 2.

[oopsIdidasuper]

@733t13 I doubt it, seeing as he never even finished HL1

[Guyect]

so... what the gunner is the ravenous bugblatter beast of traal?

[LukeAlto2007]

I think this is this way because later in the game, picking up giant objects with the Gravity gun to use as mobile cover makes a lot of sense. There's one long hallway in the Citadel that would be impossible to survive if you couldn't use a giant monitor as cover. Admittedly, though, the AI in this video is colossally stupid.

[xZOMGxLEGITx]

Hahahahahahaahahahah LAWL!

[zacskou]

11 people are valve programmers

[marosam236]

@rekku64 what the combine are saying "NO DONT SHOOT! Heavy will kill us if we destroyed his SANDVICH mayonnaise jar!

[drifter402]

ever since iv had this game the ai has been great

[OrdoMallius]

I lold hard

[kamikaze790]

That mayonnaise is a spy!!!!

[p02studios]

Good, but I couldn't belive you had so problems with munition.

On this place I had FULL store of munition...

But it's good, so small box and he couldn't shoot you...

[Georgij2010]

Прикольно, я его не вижу - он меня не видит )))

[redfoxbennaton]

Yeah, the advanced AI made me feel weird.

[silentzorah]

DON'T SHOOT. HE'S GOT A HOSTAGE.

[UnfitElvis3rd]

@silentzorah All right, put the mayonnaise down!

[ThinkWithPortals]

behold the all mighty mayonnaise!

[TheJefrey24]

When i first played it...It was hard for me to. But now I know how to bet that part.....Just run :D

[TARINunit9]

I haven't LOL'd this hard in weeks!

[TheEmerald]

ahaha i lol'd

[ActionCarl]

The worst part is that the first Half-Life actually had pretty good AI.

[BobMcCob]

@ActionCarl The first half lifes soldier AI is still good, they kill me often when i fire it up once and a while.

[Zant5976]

Solid Snake would be proud.

[Mullahgrrl]

Peek-a-Boo!

[superpuppy8722]

if i cant see him he cant see me

[pdPOINTnCLICKbq]

@superpuppy8722 Maybe Caboose was on to something after all.

[gordonfreemannr2]

HE'S GOT A JAR ABORT ABORT!

[Rekku64]

Don't mind me, I'm just a jar of mayonnaise...

[SilenceOfChaos]

@Rekku64 Hmmm... suspicious... get over here! *tastes mayo*

Mmmm! :D Okay you may pass! The ketchup and mustard went ahead of you!

Hmm... a flying window frame... hmm... *scratches head*

[LiquidFire89]

@Rekku64 what kind of mayonnaise has a radioactive sign on it?

[Bravyanz0r]

He took the can hostage.

[bgpivoter]

The worlds most advanced AI! The enemies are stunned by the psychological power of a jar!

[jordan9331]

"PILLS HERE"

[WizeDemon]

all fear the floating mayo jar

[mushroomjay]

Nobody expects a man in orange plastic pajamas to hold a medicine bottle to them in the middle of a firefight.

[red33m23]

Try this on another level and post it here..

[cbuma]

oh come on, the mayo jar was obviously bulletproof. there was nothing that poor guard could do.
