In The Dark Mod

About In The Dark mod

This mod is based on mechanics from Don't Starve game where the player will get hurt when staying in dark for too long
it simply checks for the light level in the area and compares it to the required value and if the light level is below a certain level "Below 5 in that case"
then it will inflict damage to the player on every player tick update.

Damage is scaling to the difficulty level of the provided world where damage levels are:
Peaceful = 1 DMG
Easy = 2 DMG
Medium = 3 DMG
Hard = 4 DMG

How Can I survive this?
Simply, just stay in the light above level 4 and you should be fine

There was a similar mod to that one before
Yep, Its called Deathways but it's discontinued as long as I know and it has some differences
compared to my mod, one of it is that In The Dark mod you will get killed when staying in the dark
wherein Deathways you were able to survive if you were standing under blocks, also this mod should 
compares the light level from the actual source and not from a specific block like was in Deathway
which means that modded blocks that are generating light will be working fine too
