Material Definitions

Materials

Identifier	Description
id	Unique ID. Lowercase snake_case. Must be one continuous word, use underscores if necessary.
name	In-game name displayed.
bash_resist	How well a material resists bashing damage.
cut_resist	How well a material resists cutting damage.
bullet_resist	How well a material resists bullet damage.
acid_resist	Ability of a material to resist acid.
elec_resist	Ability of a material to resist electricity.
fire_resist	Ability of a material to resist fire.
chip_resist	Returns resistance to being damaged by attacks against the item itself.
bash_dmg_verb	Verb used when material takes bashing damage.
cut_dmg_verb	Verb used when material takes cutting damage.
dmg_adj	Description added to damaged item in ascending severity.
dmg_adj	Adjectives used to describe damage states of a material.
density	Density of a material.
vitamins	Vitamins in a material. Usually overridden by item specific values.
wind_resist	Percentage 0-100. How effective this material is at stopping wind from getting through. Higher values are better. If none of the materials an item is made of specify a value, a default of 99 is assumed.
warmth_when_wet	Percentage of warmth retained when fully drenched. Default is 0.2.
specific_heat_liquid	Specific heat of a material when not frozen (J/(g K)). Default 4.186.
specific_heat_solid	Specific heat of a material when frozen (J/(g K)). Default 2.108.
latent_heat	Latent heat of fusion for a material (J/g). Default 334.
freeze_point	Freezing point of this material (F). Default 32 F ( 0 C ).
edible	Optional boolean. Default is false.
rotting	Optional boolean. Default is false.
soft	Optional boolean. Default is false.
reinforces	Optional boolean. Default is false.

There are six -resist parameters: acid, bash, chip, cut, elec, and fire. These are integer values; the default is 0 and they can be negative to take more damage.
