Armorless

Simple mod to deal damage to players when wearing armor.
Inspired by the Naked and Afraid no armor hardcore multiplayer let's play by multiple content creators.

Configuration

Configuration is done through the file armorless.properties in the config directory

# Static damage. Set to -1 to use the multiplier
damage=-1

# Take damage multiplied by the armor defense
damage_multiplier=0.5

# Make any item put in armor slots do damage (elytra, mob heads, etc.)
all_items=false

By default the amount of damage taken is half of a player's defense, for example wearing a diamond chestplate will deal 4 damage each second, which gives around 5 seconds to take it off without dying. This is so that some vanilla advancements (or modded) that require armor to be worn can be completed in hardcore without dying.
