Stealth 2.1 (Improved Stealth Mod)

Originally by -|Sparky|-, then by MaxShadow; fixed up and reuploaded with their permission by TOASTEngineer, maintained by Hidden. Turkish translation by Tora, Spanish translation by Ryo567.



Look at the first screenshot on this page; that's where the menu is. Everything inside has help text, available in EN, ES, PT-BR and TR. If your language isn't in this list, you can make your own translation and upload it to the workshop (or join our translation team).

By default, this mod supports the stuff listed below in "Compatibilities". If you want more, go to the Server Settings menu (explained above) and scroll to the bottom. Again, there is help text there. The stuff that's supported by default won't appear on the lists. Nextbots currently don't work, given how inconsistent their behaviour code is.

These instructions are for the default HUD. You may install a custom one.
The greyscale gauge shows how visible you are. The colored gauge shows how close you are to being spotted.
The arrow points to the enemy that is most likely to spot you.
The circle shows your status. This can be green (Calm), red (Alert) or flashing yellow (Evasion).


You can actually be sneaky now: Moving slowly, keeping your distance, lowering your stance, being quiet, staying in the dark, and even painting yourself to match your surroundings will make it harder for enemies to notice you.
Enemies will check suspicious things, like sounds and dead bodies (if Keep Corpses is on). You can knock them unconscious and hide them from view.
You can disguise yourself as enemies, but that feature is still in experimental phase.
There are some cool gadgets too: a throwable proximity sensor, which shows enemies through walls, a tranquilizer gun and a stun baton, for knocking enemies out, a decoy grenade, which makes a distracting bang, and an invisibility cloak, which does what the name says (and needs a keybind), but burns through your suit energy and doesn't make you silent.
If an enemy spots you, they'll call for backup, causing an Alert.
If you break line of sight with all your assailants, you go into Evasion. Avoid detection for some time and they'll call off the search and become Calm again, albeit more careful now that they know you're around.

If you're a modder and want to support this in your custom HUD, you can use the "stealthmod" global table:
-stealthmod.enablehud: (0 to 3) 0 disables the default HUD, 1 to 3 set it's style.
-stealthmod.luminocity: (0 to 255) Stores how visible LocalPlayer() currently is.
-stealthmod.alertdanger: (0 to 255) How close LocalPlayer() is to detection.

Obviously, don't use other versions of this mod along with it.

Anti-FriendlyFire mods and any mods that change NPC relationships will break this, since it works by making enemies friendly until they're supposed to see you.

Some players reported being totally invisible to NPCs. I never ran into this bug, need more info.

Enemies may ignore other NPCs upon seeing you. Probably hardcoded behaviour.

Atmos lighting does affect visibility, but it's finicky.
