The AI seeing you through grass.

[George_Smiley]

So I can't remember if I wrote about the AI seeing through grass here .... I may have.

NOTE:
I play in FIRST PERSON. I do a lot of crawling/crouching around to avoid be shot to bits, most of the time I get shot the AI are a fair way off and technically can't see me. but they can... ie. If I am prone in long grass then the AI should not be able to see me. Try it in real life if you like.

The AI can clearly see through the long grass. I have been killed twice in MP where I am pretty darn sure they could not see me. BUT they shot me dead easy as. In situ 1 they were looking through the grass over the brow of a hill. I was on one side they on the other. ( I play in first person.) The shot through the grass at me. When I was wounded in 3PV, I saw the squad clearly over the hill. They were less than 50 m away and their heads were clearly able to "see" me through the grass. I was not.
Situ 2 I was proning through long grass and a sniper in that very same long grass shot me. Even in the wounded 3PV it could hardly see them 20m away. I could only see their gun moderator sticking out a bit. There is no way they would be be able to see me.
Both occasions it was the long grass that obscured my view but not theirs. They can look over the brow of a hill through the grass and shoot. I cannot.

Stealthing around to get shot by an AI that can plainly see me even though I am in tall grass.... is very annoying.

If I can't see past my nose in long grass, neither should they.

PS. if this is confusing I can draw a diagram....

Please do yourself a favor and do 5 minutes of research before complaining about something that just is not true.

If you want an arcade experience, turn down their ability and then you can recreate your call of duty escapades.

last time i checked lying in grass didnt make people invisible.
and holding my hand infront of my eyes didnt make me invisible either...so ive heard...

[George_Smiley]

I said TALL GRASS. Non of that "facts and myths" page shows TALL GRASS.

"They can not see through any solid vegetation. Many trees and bushes are partly semi-transparent and have holes in them. And the visual appearance doesn't always reflect the actual view geometry. "

So please do yourself a favour and check your sources.

I have no idea what Call of Duty is and don't effing care, I do not want to turn down the AI abilities and I only play in First Person in MP, I have no control over the server setting anyway. Your belittling tone is quite obviously coming from some kind of ARMA3 gate keeping camp. Good on ya mate.

I will probably find more examples of tall Grass being of no service to the stealthy real player. Unless you are a third person view snowflake.

Yes AI lock onto in a similar manner missiles do, don't believe me go into zeus and press enter on an ai tracking a player. They watch you through walls even...

I really shoulda realized this was a troll account. Well that's an egg on my face.

yea dude its a debate as old as arma itself. Its certainly true regardless of what the nah sayers say. You just deal with it bc idk its arma thats what you do.

Tall grass obscures you and can make you outright unspottable, if the angle between the observer and you is just right for it.

The most accurate and telling AI detection testing suite I know of. Go grab it and see it for yourself.

>hehe no I was just trolling
I don't care. Don't troll and complain if something actually comes out of the water.

So the AI "radar" is part of the AI searching intelligence and the factors which make the AI use this being things that obscure it's IRL view etc ? So if you can't program for the grass etc then the AI will use the information. Essentially it's programming to not use their AIDAR info with exceptions to this ie "in plain view". I was slotted again today laying in grass that obscured any view below me ( I was on a hill crest ) and the enemy ran up the hill to me. They had direct line of Xray sight through the grass up the hill. I was moving so that makes it plausible that if I had not been moving they might have ignored me ( the "I saw you move" gotcha ) but in the long grass ? No way. and the so deadly accurate one shot ? In a Ghillie ? They knew where to aim without visually seeing me. and hell yes I am picky. I don't prone over hills looking for a place to snipe from for the hell of it. May as well not be grass there. I see you see me.

There is no AI radar, you are hallucinating an entire story.

[George_Smiley]

Uh huh. Have you ever considered how the AI works ? how do you think they work ? Magic? Oh let me guess you think that they actually can see. As in pattern recognition.... wow now that would be something. It of course will be the next big thing. Actual artificial vision for the AI. and how would they determine enemy from comrade? Read the DPM pattern ? The AI in this game imho are just following rules. You can throw randomness in there just to make it interesting. Just rules. and of course programming all that would be tricky. oops they can "see" through the walls. Cue bullets striking the other side of the wall you are behind.

All showcases are on expert ai settings and vanilla arma 3.

Wheat ( only shoots when I move, can't see through it or I'd be dead)

Grass (only shoots me when I move)
https://files.catbox.moe/5pihhu.mp4
A bunch of AI trying to oneshot me while all trained onto me AND having my position revealed from the start.
https://files.catbox.moe/4msvb6.mp4
A few more AI doing the same thing

Get good, or play on novice with the reduced damage tickbox. Or mod the game to make you stronger or the enemy weaker.

[the.lovewyrm]

Here, something completely stupid:
A demo where I can only walk upright, cannot fight back, can't crouch or even go prone in a mission that spawns enemies around you at all times.
Enemies are all on expert skill level.

Did I die? Of course. But I very very likely would have died sooner if I had just stood still or leaned around or whatever. Keep moving.
(I also would have lived longer if I had walked through the forest instead of around it but the test run I did before that had me living for 12 minutes while getting shot at even more, but who has time (or sub 200mb filesize) for that?)

So yeah, a dumb dumb walking around at snails speed and still not getting "terminator radar xray vision" oneshot.

None of those examples explain the AI seeing through the grass in Altis. The first example the AI is pointing right at you. It already knows you are there. Why does it not fire? No idea but it certainly does when you stand. It's aiming right at you. Is it seeing you through the grass? Is it actively seeking you out? If you were attempting to prone past it ... Maybe the trigger to shoot has not been tripped. It's not even close to the situation I am talking about. and the rest... well I am not sure what that proves. They shoot at you when you run into their "field of view"? they still shoot when you are behind the bags ? Are they leading their shots ??? Triggers. Toned down AI essentially means making them seem more human. Less automated. and doing that is obviously not a trivial task. Mistakes can be made, they may take certain events to trigger them. Like all bad detectives ruling things out because you have proof it cannot happen can in fact be a major blunder. The Alibi is perfect but false. etc. You prove a certain thing under certain conditions. or maybe you think you have. We can argue this to the ends of our days but there will be no absolute finality. The devs probably aim for mostly working correctly and move on. They probably can't be 100% certain that AI behaviour is rock solid. I am pretty sure that the AI that shot me had already seen me before. They then shot me through the grass when was in their FOV ( irl they would not have been able to see me through the grass... which is why I could not see them. ) and testing it , ah ha ha , might be harder than you think. The only way is to have "track recording" which would conclusively prove or disprove most issues. If you play Rise of Flight or Il-2 you know what I mean. It is extremely good.

why dont you bring up some examples for a change? =)

[George_Smiley]

Well how do I do that?
