Hardness

Description
As of Alpha 13, the of all blocks was set to 1. The Durability of a block is now determined by hit points (HP) for each block.

Historical Information
The  index of a material determines how much effort is needed to break the material. You can obtain this index using the Item Stats functionality added to the game in the alpha 7.6. To do this, place the mouse over an item to see the Object Stats, including its .

Calculations
Hardness is a base data for calculating Durability and Pure-Dur for blocks.

Durability
x = Hardness ÷ Block Damage (Appropriate Tool) If x = Integer  Then Durability = x + 1  Else Durability = RoundUp(x)  In words: Divide Hardness by the Block Damage of the Appropriate Tool and add one if whole number or round up the quotient.

Pure-Dur
x = Hardness ÷ 0.075 (Entity Damage Infected Survivor) Pure-Dur = RoundUp(x)  In words: Divide Hardness by 0.075 and round up the quotient.
