You should simply get the shot bot to just turn around and scan for the shooter, rather than give the bot 360 degrees FoV. In doing the 360 FoV, you're sabotaging your own ability to give the player FoV fun. So, am I right to assume that FoV only affects players and not bots? If so, "Veteran" difficulty is actually broken.



Just show the FoV overlay for a single bot, and only when the player's crosshairs is on the bot. That would simulate a real soldier actually looking at an enemy soldier to determine which sector that enemy is scanning.



Yup, you're right. Won't work. And you also can't change the "turn around too quickly" mechanism. The player's mouse can insta-look in any direction too. You'll break the game if you make the bots turn more slowly.



Did you? Exactly how does the player flee a failed stealth attempt? I tried running away with a riot shield, works. But the enemy has 360 vision and never loses sight of me.

Showing the FOV of an enemy soldier you're looking at makes sense, it could be an interesting gameplay mechanic!

Plus, regarding the 360 degree FOV of an alert guy, you know what would be cool? Having alert soldiers have a short-ranged FOV behind them. As in, they'd be able to spot the player's soldier as far as the eye can see in front of them, but would only be able to spot them from 15 meters away if coming from the back (ie, spotting the soldier by the noise he makes).
And it makes sense to have enemy soldiers under fire with no idea of how and where to get into cover in some contexts. For example, IRL, if you're shot at by a sniper from far away or with a suppressed weapon, you don't really know where it's coming from and that's what's more dangerous; that was one of the main issues for UN soldiers in Sarajevo and for both Russians and Chechens in Grozny, for example.

To get your placebos really running, you guys realize the original discussion happened in 2014?

I did the maths on the latest values that have been in since 2016, possibly earlier. For AI to pick enemies while fighting they are:
Daytime:
Low sector 230 degrees
High sector 308 degrees

Night time:
Low sector 160 degrees
High sector 230 degrees

Low sector is applied against characters that have low detectability; lowest you can get in vanilla happens by being prone and wearing the ghillie suit.
High sector is applied against characters with high detectability: running state + no ghillie suit.
Different stances and various vests get you somewhere between low and high sector.

When not alert and monitoring for enemies, the sectors are reduced by about 10 degrees.

In addition to the sector, the sight range works in much similar way.

Is there a reason for the sectors to be reduced when they're not alert and monitoring for enemies btw?
