Damage Formula

When selecting a potion item type or skill, you can input a damage formula. However, you can also use this field to execute other actions (e.g., awarding items, skills, or gold). Here's an explanation of how this works:

---

1. a (attacker): Represents the entity initiating the action (e.g., player, NPC).

2. b (defender): Represents the entity receiving the action (e.g., player, enemy).

3. Both a and b are ScriptUnit objects.

4. For items, b does not exist, and you can use level to get the item's level.

5. For states, only a and b exist.

6. For skills, level refers to the skill's level.

Practical Examples

Damage Calculation Examples:

1. Basic Damage Formula: Damage = Attacker's attack - Defender's defense

   a.atk - b.def

2. Random Damage: Generates random damage between 10 and 50

   rand(10, 50)

Custom Actions:

1. Steal Gold from Defender:

   b.UseGameMoney(10)

2. Remove Items or Gold from Attacker:

   a.RemoveItem(1, 10) or a.UseGameMoney(10)

Conditional Formulas:

1. Critical Damage Calculation: Apply (a.atk * 2) for critical hits; otherwise, (a.atk)

   critical and (a.atk * 2) or (a.atk)

Skill-Specific Damage:

1. Damage Based on Skill Level: Damage = a.magicAtk - b.magicDef + level + 1

   a.magicAtk - b.magicDef + level + 1

Item-Specific Actions:

1. Grant a Skill with an Item: When using an item, grant Skill ID 0 at Level 1 to a

   a.AddSkill(0, 1)

State Effects:

1. Continuous Damage from States: Apply 10 damage over time (minimum of 2 seconds)
