Game Mechanics affecting Nordinvasion

[Kriegstofu]

found another tidbit of information, this time about damage absorption depending on shield resistance (shield hit on your back)

This is useful for Zwei/Jugg using a 2h with a shield or RGs with 2 Shields when being used on cav with a swing from left to right while on horse (as your back moves to your front)

Code:

armor = appropriate_armor_value_for_hit_location

if hit_shield_on_back:
    armor += shield_resistance + 10

soak_factor = armor * module.ini_soak_factor_for_damage_type
reduction_factor = armor * module.ini_reduction_factor_for_damage_type

if item_flags & itp_extra_penetration:
    soak_factor *= module.ini_extra_penetration_soak_factor
    reduction_factor *= module.ini_extra_penetration_reduction_factor

randomized_soak = (random.random() * 0.55 + 0.45) * soak_factor
randomized_damage = (random.random() * 0.1 + 0.9) * raw_damage
soaked_damage = randomized_damage - randomized_soak

if (soaked_damage < 0.0):
    soaked_damage = 0.0

randomized_reduction = math.exp((random.random() * 0.55 + 0.45) * reduction_factor * 0.014)
reduced_damage = (1.0 - 1.0 / randomized_reduction) * soaked_damage

if (reduction_factor < 0.00001):
    reduced_damage  = 0.0

damage_difference = round(reduced_damage + randomized_soak)
effective_damage = randomized_damage - damage_difference

if hit_bone == head:
    effective_damage *= 1.2

    if item_is_ranged:
        effective_damage *= 1.75
elif hit_bone == calf or hit_bone == thigh:
    effective_damage *= 0.9

effective_damage = clamp(effective_damage, 0.0, 500.0)

the important part here is  

Code:

if hit_shield_on_back:
    armor += shield_resistance + 10

which means the higher your shields resistance is, the higher your backs total armor rating is

this only counts for projectiles, not for melee hits
