HOW DAMAGE SYSTEMS WORK

Damage models in video games determine the health loss inflicted on a target when an attack hits. Different games use different damage formulas:

🛡️
Flat Subtraction Armor: Damage = Max(0, Attack - Armor). Easy to balance for tactical shooters and arcade flight games.
⚡
Critical Hit Scaling: Multiplies raw damage on weak point hits (e.g. headshots, cockpit strikes).
🔥
Percentage Mitigation: Armor acts as effective health (e.g. Damage = Attack × (100 / (100 + Armor))).

CALCULATION FORMULA

This calculator uses a deterministic flat mitigation formula widely used in real-time combat games:

Final Damage = max(0, (Base Damage × Crit Multiplier × Damage Multiplier) - Armor)

Developer Note: Different games implement custom mitigation curves. This tool uses the displayed formula to help prototype weapon balancing and damage thresholds.

FREQUENTLY ASKED QUESTIONS

Common questions regarding game combat math, damage balancing, and armor mitigation.

What is the difference between flat armor and percentage armor reduction?

Flat armor subtracts a constant number directly from the incoming damage (e.g., 100 dmg - 20 armor = 80 dmg). Percentage reduction reduces incoming damage by a proportional fraction (e.g., 20% armor turns 100 dmg into 80 dmg, and 1000 dmg into 800 dmg). Flat armor makes rapid low-damage weapons ineffective against heavy armor.

How should I balance critical hit multipliers in an action game?

Most standard shooters and combat simulators use a 1.5x to 2.0x multiplier for critical strikes. High precision weapons like sniper rifles or precision railguns frequently use 2.5x to 3.0x to reward accurate aiming.

Can damage drop below zero?

In combat design, damage is clamped using Math.max(0, damage - armor) or Mathf.Max(0f, damage - armor) in Unity C# so that high armor values do not heal the defending player.
