Damage Plugin

Name: The name of the damage type.

Resistance Stat: The resistance stat used when calculating the damage done for attacks using this damage type.

Damage is calculated based on this algorithm:

dmg-base,dmg-max - damage from weapon (player) or defined on mob
effect_dmg - effect damage
useHitRoll - false for DoTs and true for the rest damage effects
PHYSICAL_POWER_STAT - strength for physical attacks and potential for magical attacks
DAMAGE_DEALT_MODIFIER - at this point default value is 0
DAMAGE_TAKEN_MODIFIER - at this point default value is 0
hitRoll - random between 0-100
DAMAGE_HITROLL_MODIFIER - game settings global parameter (by default with value 35)
targetArmor - target resistance to the attacked damage type
FLAT_ARMOR_DAMAGE_CALCULATIONS - game settings global parameter (by default with value true)
DamageMod - damage modifier defined in the effect
skillMod - skill modifier defined in the effect
criticalChance - character statistic (magical_critic or physical_critic)
bonusDmgEffectVals - if Bonus Dmg Effect is on the target (from the effect definition) then add Bonus Damage Ammount value
PVP_DAMAGE_REDUCTION_PERCENT - game settings global parameter (by default with value 0.1)
PVP_DAMAGE_REDUCTION_USE - game settings global parameter (by default with value true)



d1 = effect_dmg + random(dmg-base,dmg-max)+ ammoDamage + skillMod * skillLevel;

d2 = d1 + d1*(PHYSICAL_POWER_STAT / 25);

Hit Chance is calculated based on this algorithm:

targetLevel - Targer character level.
casterLevel - Caster character level.
HIT_CHANCE_POINT_PER_PERCENTAGE - Global parameter adjustable in the Game Settings Plugin. Defines the number of points per one percent of hit chance.
HIT_CHANCE_PERCENTAGE_PER_DIFF_LEVEL - Global parameter is adjustable in the Game Settings Plugin. Defines hit chance reduction by percentage per level difference between defender and attacker.
HIT_CHANCE_PERCENTAGE_CAP - Global parameter adjustable int he Game Settings Plugin. Defines maximum chance for miss.

statDiff = ((evasion - accuracy) / HIT_CHANCE_POINT_PER_PERCENTAGE);
if (statDiff > HIT_CHANCE_PERCENTAGE_CAP) statDiff = HIT_CHANCE_PERCENTAGE_CAP;
if (statDiff < 0) statDiff = 0;
int levelDiff = (targetLevel - casterLevel) * HIT_CHANCE_PERCENTAGE_PER_DIFF_LEVEL;
if (levelDiff < 0) levelDiff = 0;
hitChance = 0.95 - ( statDiff / 100f + levelDiff / 100f );

Parry is calculated based on this algorithm:

targetLevel - Targer character level.
casterLevel - Caster character level.
HIT_CHANCE_POINT_PER_PERCENTAGE - Global parameter adjustable in the Game Settings Plugin. Defines the number of points per one percent of hit chance.
HIT_CHANCE_PERCENTAGE_PER_DIFF_LEVEL - Global parameter is adjustable in the Game Settings Plugin. Defines hit chance reduction by percentage per level difference between defender and attacker.
PARRY_PERCENTAGE_CAP - Global parameter adjustable int he Game Settings Plugin. Defines the maximum chance for parry.

statDiff = ((parry - accuracy) / HIT_CHANCE_POINT_PER_PERCENTAGE);
if (statDiff > PARRY_PERCENTAGE_CAP) statDiff = PARRY_PERCENTAGE_CAP;
if (statDiff < 0) statDiff = 0;
int levelDiff = (targetLevel - casterLevel) * HIT_CHANCE_PERCENTAGE_PER_DIFF_LEVEL;
if (levelDiff < 0) levelDiff = 0;
parryChance = 0.05 + ( statDiff / 100f + levelDiff / 100f );
