Improved Stealth Mod

This mod allows you to hide in the shadows, remaining undetected to enemy NPCs. Lighting and movement will alert them. In this state, you can't hide anymore, but if you stay out of their line of sight, they will eventually stop chasing you. This is based on an old mod made by -|Sparky|-. He lets everyone modify it, so I took the source and tried to improve it with new features. At first it was only for personal use, but then I decided to upload it. This is the first thing I make in LUA, so there may be bugs. Feel free to post them here, and I'll try to fix them asap. I'm also open for suggestions, but my programming knowledge is a bit limited, so I may or may not implement them.

I left the game, and I won't work on this addon until I return. Don't expect any more updates until then.
User Schilcote has made his own branch of this mod, with my permission. You can find his version here:

Theres a FAQ (Frequently Asked Questions) in the discussions section. Read it before asking something.

- Enemies sight range is affected by your light level and movement speed. Also, it's halved if you are crouching.

- Enemies can hear you, even through walls. Always walk or crouch when approaching an enemy from behind.

- Once alerted, they will inmediately start chasing you, and you can't hide anymore. Stay out of their line of sight for a few seconds and they will lose track of you.

- Includes HUD elements to keep track of your light level and alertness of enemies.

- Optional music, sound and visual effect for when an enemy detects a player.

- You can change most internal variables with console commands or in the toolmenu. These settings are located in the Options tab.

- You can change what weapons are silent, or make less noise, and what kind of NPC's are affected by this mod (by default, only Combine Soldiers and Metrocops). These lists are located in "Garrysmod/data/stealth". Remember to reload them in game.

- Includes two stealth tools: Sound Grenade and Proximity Sensor.

- Support for Cardboard Box swep by Olivia. Enemies will ignore you if you hide inside the box, as long as you don't move. You can find it here: https://steamcommunity.com/sharedfiles/filedetails/?id=317267606

- Enemies will alert nearby NPCs if they detect you, unless you kill them quickly.

- Enemies will investigate dead bodies. You need "Keep Corpses" on for this to work, or you can enable "Keep Corpses Override". Disable both if you're using Gibmod or Blood and Gore Overhaul.

- You can press USE to grab enemy corpses (only for those affected by this mod).

- You can override the original relationship between the player and the NPCs included in npc.txt. This way you can make this mod work with friendly NPCs.

CW 2.0
FA 2.0 Alpha
TFA Official Weapons
TFA NMRIH
TFA CSS
TFA CSS Alternates
TFA CS:GO
Half Life 2
Half Life Reanaissance
Some M9k Weapons

- Add A minimap with nearby enemies and their line of sight (quite unprovable)

- Make a Wire component that alerts nearby enemies, so players can build their own security systems.

- Add support for Atmos.

- Make enemies hear players talking with the mic.

- Make players harder to detect while underwater.

- Enemies will detect you even if you have "notarget" on. However, they won't attack you.

- When a player is detected, enemies will try to kill him, ignoring other NPCs.

- Sometimes NPCs will turn back if the player fires a weapon, even if he wasn't supposed to hear that. Thats because the default NPC ai can't tell if a weapon is suppressed or not.

- If you kill an NPC which is inside the range of a proximity sensor, it will show an holographic copy of itself for one or two seconds.

- "Anti-FriendlyFire (NPC)": With this mod, you won't be able to hurt unalerted enemies, because they are treated as allies until they spot a player.

- Any mod that modify NPC relationships (like iNPCs): If enemies attack even before spotting you, then this may be the problem.

- Any SNPC.

Big thanks to -|Sparky|- for making the original mod, and letting everyone modify it. You can find it here: http://steamcommunity.com/sharedfiles/filedetails/?id=185904454.

Thanks to Clavus for his SWEP Contruction Kit, which allowed me to attach a tin can to a pistol as a suppressor, Brink style (?

Also thanks to Olivia for its cool Cardboard Box SWEP, and for letting me use her alert effect in my mod.

By the way, I was using CTP (Customizable Third Person) in the screenshots. The map is Freespace 13
