(not really) Fixed Night Vision

Something-something, gmod broke things again with updates, if it works for you, lucky I guess.

The fixed version of the Nightvision mod released back in 2014. Fixed constant flow of LUA errors by solving some problems here and removing one function I couldn't brurteforce fix there. Removed function is "Film grain" effect, that originally could be turned on or off. All other functions remained unchanged or got bruteforce fixed. "Bruteforce fixed" because my knowledge of LUA only allows me to fix obvious errors.

So far I've been unable to catch what causes it, but there is a chance that for you this mod will still be an error. Just make sure to unsubscribe from original mod to make sure it won't screw you over

Features remained after the bruteforce fix:
- Completely client-side (other people won't see you use this)
- Highly customizable
- Night Vision and Forward-Looking Infrared Thermal Vision goggle types
- ID (Illumination-Detection)
- ETISD (Eye Trace Illumination-Sensitive Detection)
- ISIB (Illumination-Smart Intensity Balancing)
- AIM (Alternate Illuminating Method)
- FLIR (Forward-Looking Infrared)

Q: How different is it from other night vision scripts?

A: Unlike most scripts, this script actually illuminates the area around you instead of simply modifying on-screen colors

Q: How customizable is it?

A: You can:
- Modify the illumination radius
- Modify the brightness of the illumination
- Modify the speed of how fast the night vision turns on
- Modify the needed darkness level for ID work (described below)
- Modify the reaction time of ID
- Modify the range at which ETISD works (described below)
- Modify the sensitivity of ISIB
- Modify the range at which AIM works
- Switch between FLIR thermal vision and the regular night vision
- Toggle on/off a distortion effect
- Toggle on/off a blur effect
- Modify the intensity of the blur effect
- Toggle on/off a green overlay effect
- Toggle on/off a goggle effect
- Toggle on/off a bloom effect
- Customize the amount of alpha passes
- Easily reset everything

Q: I bet it works only on console commands

A: Yes, and no. You can access an in-game menu by going to Q > Options > NVScript > Client.
You can also control everything using the console commands (command names are below)

Q: Do I need any additional games for this to work?

A: No, all the needed materials are included. (5 materials)

Q: My night vision goes all crazy when I have ETISD turned on!

A: Turn it off or decrease the range at which it works.

Q: ETISD doesn't seem to work.

A: ETISD only works with ID turned on.

Q: I've been playing around with the controls, and was writing in numbers instead of using the slider, and now the night-vision is messed up!

A: You should only use values within the slider limits. Press the "Reset Settings" button.

Q: I'm having performance issues.

A: Reduce Illumination range, increase Brightness to 1.0 (100%), turn OFF the Distort effect, turn OFF the Bloom effect, turn OFF the Goggle effect, turn OFF Blur, turn ON ISIB.
The recommended settings of the night-vision are set when you reset the settings.

Q: The menu looks complicated, and I don't even know what does stuff like ID or ETISD do!

A: Read below.

Q: Can I get banned for using this?

A: If you run around the server and scream "I'M USING A NIGHT-VISION SCRIPT", then maybe.
Although you shouldn't get banned unless you're using this in a gamemode where the enemy needs to be lurking in the shadows and you openly brag about using a night-vision script.
And no, you can't get VAC banned for this either.

Post Scriptum

Last update to the mod was released back in 2014, thus I came to a conclusion that official support for it is over and the mod is abandoned. It would be a shame to just let the mod die because of the game update so long after the initial release, so I took opportunity to fix it to some extent and let it live. However, I think that I should give proper cretit to the original creator and their work.
