armourPiercingFactor(armourPiercing, hardness): number

Defined in: src/ships/weapons.ts:478

How much of a weapon's damage a hull's hardness lets through.

number

The weapon's piercing rating.

number

The target hull's finite, non-negative Ship.hardness. Pass 0 when the hardness is unknown, which disables hardness scaling.

number

A factor in [0, 1]: 1 when the weapon out-pierces the hull, otherwise armourPiercing / hardness. A zero piercing rating returns 0 when hardness is positive; zero hardness always returns 1 because it disables hardness scaling. Applies to hull damage only — shields do not care.

If either argument is not a finite non-negative number.
