Will the A.I. react to the flash-light?

Roland Deschain · Jul 18, 2004

In Far Cry is a soldier is just around the corner in a dark room and you turn on the flashlight and wave it around, he does not react to it at all (don't even come to investigate).

With the advanced A.I. in Half-Life wouldn't if be nice if the A.I. actually took notice of such things. Nothing major, just it would amp the immersion factor so much.

Dead-Inside · Jul 18, 2004

1. We don't know, ask VALVe. (Maybe you should have asked yourself; "Who would know?"...)

2. I'm guessing YES. Why wouldn't they? Think real life. It's HL2. Coding them to react to light isn't that hard.

For as smart as the AI look in the video's Im gussing yes.

guchi · Jul 18, 2004

im guessing yes too

Mr-Fusion · Jul 18, 2004

I wonder if characters flinch and cover their eyes and tell you to "**** off" when you shine the light right into their eyeball?

Perret · Jul 18, 2004

I'm guessing no, because maybe its like HL Multiplayer and the flashlight only light the player and not there where he is blending with his lamp.

Yeah i get you, but the hl2 flashlight lights up everything in a circle. Not just a specific target.

Check the pic. http://www.hl2fallout.com/screenshots/albums/screenshots/hl2flashlight.jpg

I'm guessing ... not likely. But i'm hopeful. Worth an email.

Daiceman9 · Jul 18, 2004

i think it would be really cool if you implimented a flare type effect if you shine the light in someones eyes.

Xrenity · Jul 18, 2004

the blinking eyes were calculated with the amount of light, weren't they?
At least gabe said so E3 2k3, zo I guess the chars will blink a bit more when you shine the flashlight on them?

Crusader · Jul 18, 2004

Maybe HDR would make that kind of feature automatic, does anyone know this for sure?

They have that effect for the scanners taking photos, anyway

charybdis · Jul 18, 2004

I wonder what happens if you flash the light in the main character's eyes. It would be kind of cool to shine the light on say, Alyx, and she then tells you turn it off or stop or something. That would also be a cool effect to add to the experience.

I wonder if their pupils would contract, too. Wishful thinking, probably... but I wouldn't put it past them.

The Monkey · Jul 18, 2004

And if you could blind them temperary if you point the flashlight at their eye, that would be nice, wouldn't it?

PowerLlama · Jul 18, 2004

I'm going to say no, just to go against the grain.

Your english is okay by all means.

And multiplayer and singleplayer are different things... NEVER think "Blah is not/doesn't work in multiplayer and thus isn't in single player)... ever... But yeh.

Edit: Oh, and this is HL2... Not 1.

Crusader · Jul 18, 2004

Well we will see soon enough hopefully...

I'm afraid to say I can never really imagine myself playing HL2, it's has some mystical quality which makes you feel like it could never really come true.

I just hope I am paranoid

... HDR is for displaying, it has nothing to do with A.I. reactions. Sorry.

Crusader · Jul 18, 2004

Ummm yeah, I should have made clear what I was answering. I was answering this post:

Dead-Inside · Jul 18, 2004

Oh, well, still your fault but okay

Sorry then.

Some_God · Jul 18, 2004

Im guessing no... its not like they are going to be like "OMFG GAY THAT LIGHT OUT OF MY FACE... YOU HAXXOR!!"

ShadowFox · Jul 18, 2004

I doubt it. I don't expect HL2 will be a very stealthy game, thus a feature such as that wouldn't affect gameplay too much.

A True Canadian · Jul 18, 2004

I think that the bugs (Antlions) will be attracted to the light just like the insects of the world.

The combine probably use some sort of vision enhancer or something (they have masks covering their entire face and their eyes) so I don't think that they will be affected.

We will see.

RogueShadow · Jul 18, 2004

Ever shine a flashlight on the floor and move it around, while watching your cat (or dog) chase it?

I think this would be cool.

THATWACKYDANTE! · Jul 18, 2004

well I know in The Chronicles of Riddick: Escape from Butcher Bay the soldiers reacted to your shotties flashlight and everything, only thing I wish more A.I. would notice is shadow's approaching them from behind (Light is behind your char. walking upon an enemy)

EVIL · Jul 18, 2004

I think it would be possible for mods, make it a weapon that shoots a constand invisiblebeam and where the beam hits surface you could spawn somesort of entity that the AI can focus on like those "AI hint" entities valve speaks of

operative lm · Jul 18, 2004

Maybe you could shine the flashlight in the face of a Resistance fighter in a battle. It would blind him long enough to get shot.

Rafa 5.0 · Jul 19, 2004

Yeah wishful thinking, but maybe they're saving this more "advanced" reaction to the light for HL3.

Sorze · Jul 19, 2004

Err, this is a bit offtopic, but.... still, I noticed something in the screenie posted here.

The shadows aren't all that dynamic (they usually aren't in HL2) as seen on the antlions' shadows, but there's something in the background that seems to be casting a shadow 'properly', see that thing in between the antlions?
I'm guessing that's a moveable physical object, so am I to suppose that those have dynamic shadows then?

I'm not sure what things are supposed to have dynamic shadows, and I (think) have heard several statements from valve people about using only dynamic lighting/shadows so i'd say it's possible the shadowing is dynamic on atleast certain objects, anyone care to enlighten me?

Sorry if I'm unclear, tired... late... zzZZzzz

No, no, I think this may actually be true. Or atleast I'm pretty sure it would be possible to do. I remember Gabe saying something about the eyes was controlled by local radiosity calculations. This leads me to believe that it wouldn't be too hard to have pupils change size based on light levels. Does anyone know what exactly that quote was in the e3 2k3 video?

CR0M · Jul 19, 2004

It's all true.

Also when you fire a gun next to somebody they put their hands over their ears and shout "Holy **** you made me deaf you retard" and then suffer in later life from impaired hearing. It's all true, it says so in my brain.

Cyber$nake · Jul 19, 2004

Well if any of you remember how in one of the CS:S vids when the guy went form a dark room to a bright room everything was glared for a min. before going back to normal- perhaps there would be a similar glare effect if someone shined their flashlight at your face in Sp or MP.

"The eyes are controlled by radiosity calculations, they self-shadow and move along with you."

DevgruSeal · Jul 19, 2004

If not, its easily scriptible.

But my guess is, yes, they will, considering HL2 is supposed to be realistic (not in the sense of striders and zombies trying to overtake the earth..) as it can be...Physics wise

Runteh · Jul 19, 2004

I hope that when you have the torch on:

You don't glow like a christmas tree
You can see the beam through the air quite faintly (from 3rd person)

Dalamari · Jul 19, 2004

Runteh, to see a faint beam thru the air it would need to be VERY smokey, and quite hard to code since the smoke would need to be a element instead of a sprite.

CR0M · Jul 19, 2004

classic case of hope breeding dissapointment. Aren't you guys getting a little too over imaginative here?

Will the A.I. react to the flash-light?
