That's Lit - Logical AI Vision

Quote from Goflishe

I'm having issues with the 3.6.1 version where the bots don't shoot at me even if I'm right up against them. It's happened 3 times in a row on night factory.

• What mods do you have?
• What bot difficulties?
• What SAIN settings?
• Any option changed?

I tweak things here and there randomly in every version, so I may not be able to provide effective support for older version.

Quote from Goflishe

I just left all the options the same as they came for your mod. I also noticed that your light/dark meter would stop displaying anything after about 20-30 minutes even if I was in a really bright or dark area.

HUH, that seems like the script straight died... that's very weird.

Now I also need your bepinex log for that.

Well yeah

Nothing related in this log, did it happen in that session?

I noticed your preset is based on Normal, can you try Hard or something and see does it happens again? Because It could be that the preset already give bots a slower visual confirmation and ThatsLit amplify the delay even more.

It's SAIN's vision speed. (TBH I think hard is about right with That's Lit, I've seen several people complain things getting too easy)

Quote from Goflishe

And also how does your darkness/brightness scale value work?

But I think people shouldn't touch those unless they want to spend quite some time to find a good balance.

That's Lit - Logical AI Vision 1.2.4

• Properly checks if an AI is a boss (previous method probably maybe possibly could be inaccurate)
• Updated meters visual, using halfwidth unicode characters now
• Changed how scope affects AI, now about 25% of the time sighting range is factored in, instead of when the AI is "aiming", because I doubt they actively search with scopes when not engaged
• Disable details (grasses) check on Lab

A reminder by the way

If you have issues like bots are basically blind to you, and you have SAIN installed, please…

• Cap stealth from common grasses
  • In previous versions, the player can gain unreasonable stealth from very dense grass cluster even though they are short and can not cover crouching player
• Buff stealth from fog
  • In actual gameplay, the highest fogginess I've seen is 0.087, but in previous versions the maximum is assumed to be 0.35 which results in the calculated buff is very small
• Fog, while unlikely, can now make bots overlook players from afar
  • Impact to vision from fog is all about distance, which is

That's Lit - Logical AI Vision 1.373.2

In of the short lived 1.373.1, an immediate CRITICAL hot fix just appeared! How cool is that!

• Fixed and reworked impact to bots' vision from their active scope.
  • The mod has been using sighting range to simulate bot using scopes to spot players, which is somewhat relevant to scopes' optic zoom but still, wrong. It now properly uses scopes' optic zoom.
  • Extra explanation of the existing mechanic:

  • The mod has been using sighting range to simulate bot using scopes to spot players, which is somewhat relevant to scopes' optic zoom but still, wrong. It now properly uses scopes' optic zoom.
  • Extra explanation of the existing mechanic:
    • Scopes only buff bots when they are facing the player (the angle is scaled down for higher zooms) randomly (more likely to happens if the bot is not moving). Bots using goggles don't get buffed.
  • Because bots don't, the mod now sometimes switch bots' current scope mode.
• [NERF] Thermal scopes and goggles are now factored in.
  • For bots with thermal on, darkness doesn't work, neither grasses and bush ratting. These rich mother fuckers will be surprisingly deadly.
• Reworked overhead overlooking, in hope to make it more usable yet balanced, though the difference is probably hard to tell.
• Player and bot movement are now applied as final modifiers.
  • [NERF] The player will be spotted faster according to the moving speed, unless it's really dark. Will not make it faster than unmodified by That's Lit.
  • [BUFF] Sprinting bots will less likely to spot players not in front.
  • [NERF] Bots not moving will spot the player faster. Will not make it faster than unmodified by That's Lit.
• [BUFF] Added a small chance for bots outside to fail to spot players inside. Does not work when the bot is looking straight toward the player, or at closer distances.
  • "Inside" is defined by BSG. Proper buildings with walls and ceilings usually count... of course, there are weird exceptions.
• [NERF] A new patch to extend distance to see the player when the player is lit up.
  • SAIN does not have access to lighting data, thus it scales down bots' vision distance just by time and weather. Vision distance decides whether vision check happens, this means, no matter how much the player is lit up, bots remains unable to see the player if the distance exceeds the SAIN modified value, this results in getting lit up does not hurt.
  • When the player gets lit up by non-ambience lighting, bots' vision distance check against the player is scaled up according to the extra brightness (with a bot randomness, of course).
  • Also scale the distance up for AIs using NVG when the player has ir laser/light on.
  • A config is provided to scale down this feature.
• [BUFF] Due to how plants sucks all light and looks extra dark in nights, the brightness score of the player now gets a extra reduction if there are an amount of foliage around the player (as an alternative way to detect if the player is among trees and foliage).
  • A smaller reduction is also applied in day time to mimic advantages from shadows in forests.
• [NERF] Nerfed Encountering Patch so only sprinting bots get considerable impact on encountering the player.
• Fixed a bug making bots friendly when the mod is disabled out of raid.
• Tweaks.

That's Lit is now feature-complete! I expect less new features and major changes from now on.

The version format now features the parent SPT version, for example, if there are 2 versions: 1.373.x & 1.375.x:

1.373.x should works on SPT 3.7.3 and 3.7.4, while SPT 3.7.5 would requires 1.375.x.

This should be compatible with SPT 3.7.1 and 3.7.2.

That's Lit - Logical AI Vision 1.373.3

This release polishes new features and iron out bugs from 1.373.2.

• Fixed brightness not buffing bots.
• Improved Extra Distance Patch so it'll take effect more accurately only when the player is lit up in darkness. Also make it buffs bots using NVG not only when the player has ir lights on.
• Added a terrain meter of surrounding grasses. A lot of mechanics, including grasses, are applied per bot so this only gives you a rough idea.

• Tagilla is now excluded from the includeBosses option. Its special AI does not fully work with values from That's Lit and sometimes it's bugged out and becoming friendly.
• Tweaks and fixes.

ThatsLit.Utility class now contains 3 new methods for modders to add supports for custom lights/lasers/scopes, you can call it directly or via reflection (soft-dependency):

C#

void RegisterExample ()
{
    Type type = Type.GetType("ThatsLit.Utility, ThatsLit");
    if (type == null)
        return;
    var m = type.GetMethod("RegisterCustomLightAndLaser"); // or RegisterCustomNightVisionScopes, RegisterCustomThermalScopes
    if (m == null)
    {
        LogWarning("ThatsLit endpoint not found.");
        return;
    }
    m.Invoke(null, new object[] { templateId, mode, light, lightIsIR, laser, laserIsIR }); // RegisterCustomLightAndLaser (string templateId, int mode, bool light, bool lightIsIR, bool laser, bool laserIsIR)
    // RegisterCustomNightVisionScopes (string templateId)
    // RegisterCustomThermalScopes (string templateId)
}

That's Lit - Logical AI Vision 1.373.5

This release features a bug fix, an optimization and a new performance info.

• Fixed a logic error in Encountering Patch which luckily still has been working correctly.
• Convert the pixel iteration in lit score calculation into a Unity job (which gets dispatched to other threads). It won't give much, but should still save some precious main thread time.
  • If you notice fps improvement on your system, please leave a comment about it.
• The LowResMode option is converted to a level range of 1 - 4.

  • If you notice a fps difference on your system, please leave a comment about it.
• The LowResMode option is converted to a range of 1 - 4. Level 1 is equal to original true. Level 2 is equal to original false.
• An benchmark option is added for people interested to see actual ms spent on That's Lit calculation. It's part of the Debug Info.
  
  • It does not cover 100% of the mod but shows all the major calculation and patches. Unfortunately only the mod code can be wrapped thus the overhead from Unity stuff (e.g. the observer camera) can not be shown.
  • To understand the numbers: To maintain 60FPS it requires everything (vanilla + mods) costs less than 16.67ms (6.94ms for 144FPS ).
  • 
  • Don't worry about the GUI cost, at least 95% of it comes from rendering the ever changing Debug UI, it's very very cheap if you keep the Debug UI disabled.
  • Note: the existing AFFECTED info shows how many times the main calculation is executed, the +N number resets every 47 frames, with the starting-pmc-only Donuts presets, sub +200 is totally normal and fine.
