📋 About This Mod
Revamps weapon and armor durability with RPG mechanics, including an option to disable durability.
# Brief Summary
This mod overhauls the durability system using coherent, RPG-inspired formulas.
The formulas have two components:
- Basis: A constant value that never changes and represents the minimum durability loss that every weapon or armor will receive.
- Skill: A modifier where weapon durability scales with skill stats and armor durability scales with SPECIAL stats.
Higher stats result in more resilient items, but they will not last forever (unless the basis is 0 and, in-game, the skill is at its maximum).
Note that 'basis' and 'skill' components can be modified in the INI file.
# Explanation
Weapons degrade per shot based on the following formula:
fWeaponBaseHealth + ( ((100 - Skill) / 100) × fWeaponSkillMult)
Default values:
• Skill = Big Guns, Small Guns, Energy Weapons, Unarmed, or Melee Weapons
• fWeaponBaseHealth = 0. 3
• fWeaponSkillMult = 0. 5
Both fWeaponBaseHealth and fWeaponSkillMult can be modified in the INI file.
Armor degrades per hit using this formula:
fArmorBaseHealth + ( ((10 - SPECIAL) / 10) × fArmorSkillMult)
Default values:
• SPECIAL used in each case:
• Strength → Power Armor & Armors with weight ≥ 25
• Endurance → Armors with weight ≥ 15 and < 25
• Agility → Armors with weight < 15
• fArmorBaseHealth = 0. 5
• fArmorSkillMult = 0. 5
Both fArmorBaseHealth and fArmorSkillMult can be modified in the INI file.
# Vanilla Mechanics
## Weapons
Weapons degrade based on the formula:
fDamageToWeaponMult × WeaponBaseDamage
Problems with this system:
• Stronger weapons degrade faster (example of two weapons with the same health points):
- Chinese Pistol: lasts 1250 shots.
- 10mm Pistol: lasts only 556 shots.
• Lacks RPG depth and customization.
Note that 'fDamageToWeaponMult' refers to a set of GameSettings, where * can be replaced with 'Gun', 'Energy', 'Melee' and 'Launcher'
