hi im thinking about right damage calculation because i found different calculations on different pages, so idk. I mean calculation containing epf value (original vanilla calculation ) from pocketmine: PHP: $itemDamage = 3;$armorModifier = $itemDamage * $armorPoints * 0.04;$finalDamage = $itemDamage - $armorModifier; from http://minecraft.gamepedia.com/Armor : PHP: $finalDamage = $itemDamage * ( 1 - min( 20, max( $armorPoints / 5, $armorPoints - $itemDamage / ( 2 + $toughness / 4 ) ) ) / 25 ) * ( 1 - $epf / 25 ) and from different unknown webside: PHP: $finalDamage = $itemDamage * (1 - $armorPoints * 0.04) * (1 - 0.75 * $epf * 0.04) I assume, pocketmine calculation is wrong, because it subtracts armorModifier from iteDamage and its not equal to other calculations. But 2 other calculations are similar, only first of them calculates damage with doughness and some min(), max() operations. So my only question is what calculation is right one because all are different or mix all calculations and create new and right calculation?
