X-Ray Vision AI

[metalcraze]

@erupter: if they spotted you they would be shooting at you instantly, not running for cover. Running for cover without shooting is a reaction to gunshots from an unknown target for ArmA2 AI. Nothing else. They clearly reacted to gunshots not you.

Player is dead 1 minute after, being running since spotting

LOL so you ran instead of going prone to stay hidden and it took them a whole 1 minute to really spot you and kill you while you were running around. What's the problem? Where's the X-ray vision?

This is how silly myths are born.

My team was being engaged by another squad 500m or so south-west. My bino were pointing north-north-west in the video.

In that case they already knew where to look for you.

And I'm critizing the fact that I was complitely unable to see them without binoculars while they saw me instantly through foliage and without vision aids.

Er, they have very clear line of sight to your entire standing body. How could you not have seen them? Is your resolution turned down to that of an Iphone? They saw you 'instantly' because vision travels at the same speed as light. Were they not scanning for an enemy already in your vicinity, they would have proven quite numb.

I don't understand what prevented you from seeing them first. If the foliage actually covered the gap in the trees before you zoomed with the binos, then that is a model/LoD/texture streaming issue in the engine and/or your computer, not an AI issue.

Dont hold your breath theres nothing in this community thats impossible and Yes there is a mod and its adjustable too.
see here:

from the thread of the mod:

Fun testing results:

- With Audible at 0 enemy units cannot hear you at all, unless you fire a weapon, but can still see you (good for stealth adjustments).
- With Camouflage set to 0 enemy units cannot see you at all, unless you fire a weapon, but can hear you move (you can run around them in a circle, LOL)
- with both set at 0 enemy units cannot see nor hear you, once again unless you fire a weapon.

@NoRailgunner
LOL! That was great!

Although the ai does not in any way cheat I believe their spotting abilities are not exactly equal with a human's. The main problem is that they are not "confused" by complex scenes. If a human looks at a open field with a person in it they will pick out that person instantaneously because the person contrasts so much with the surroundings. Now if you take that same situation but made it a forest instead of a field, even if that person was still in plane view, it would take much longer to spot him. This is because the human eye is confused by all the trees, and the person "blends in".
This does not apply to the ai however. If your in view they see you just as easily no matter what terrain you are hiding in. I think this is the cause of alot of the "ai has xray vision"/"ai sees through trees/bushes myths". heres what I wrote about it awhile ago...

But what about complex terrain like forests. I think the ai spots to easily there. I don’t mean they cheat, or see through bushes/trees, I just mean that they don’t get confused like a human would when looking into these areas. The time it takes a human to see someone in open terrain can be half as much as that needed to spot someone in a relatively populated terrain. Even if they aren’t hiding behind something. Just compare this (open) to this (slightly complex). there isn't even that many bushes in the second and still i find it much harder to spot the enemy. But for an ai this does not apply. No matter what terrain you are in they see you just as well as long as you are exposed. I think this could use improvement not only to make ai have more realistic capabilities but to also make terrain have a bigger impact on game play and tactics, even when involving the ai.

And heres an example why some people get frustrated with the ai. If I take up a position like this, or like this, it doesn't matter to the ai. They'll still see me just as easily and just as fast.

this also works the other way around though. players are able to pick out enemies in the open much easier than ai.

I hope that this kind of thing is improved at some point as it will lead to more importance to terrain whan planning, and if done right, could make the ai use more area fire resulting in better firefights.

Full disclosure: There's a glitch that still bedevils BIS where the AI can see through the *trunks* of trees.

You mean the thread few months (?) back in one of the beta threads? Wasn't that a case of only *some* tree trunks being bugged? I remember some comparison pictures with red and green fluffy clouds visualising knowsabout or such stuff ;-)

Maybe the fact they were two pixels tall in total?
Man you (and I) are staring at a monitor that struggles to represent our entire field of vision in just a few inchesand with just so many pixels.

300 meters in dense forest with grass translates in just a few grey (if you are lucky) pixels.
You can pause the video and try to see before I put on the binos.
I could even give you the full res thing.
Fact is you can't be 100% sure it's not a rabbit or a cow or whatever: it's just a teenie-tiny grey patch in the distance.
They ought to have the same problem.
Fact is they don't.

Proven in countless other missions.
Especially night vision gives me the creeps.
