This mod allows to have a night vision or thermal by using a code.
For the night vision write "night"
For the thermal vision write "thermal"
For the normal vision write "off"

Sorry for my bad english.

Correcting :

- Now when you die the mod will automatically reset to 0, you will no longer oblige when you die to rewrite off, Now just to rewrite the code it again for have the night/thermal vision.
