Changing damage calculations in RGSS2/VX

[thelandarian]

Seems simple enough; I was easily able to do this in XP/RGSS, but I'm stumped doing this with VX/RGSS2.  I would like to modify damage to where defense is calculated not as a set value, but as a percentage.  I.E., if a foe has a defense of 100, it would mean damage is reduced by 100%- he is normally unaffected by physical attacks, whereas if the foe's defense is 50, it means physical attacks are basically cut in half.  I understand the calculations, but I don't know what variables and classes these are assigned to in VX/RGSS2.  I spent some time browsing through the built-in classes, but none of them seem to deal directly with calculating damage (I do recall in XP, it's in the Game_Battler 3 class), so I don't even have a template to work with in VX/RGSS2.  Any help would be greatly appreciated!  Thanks!

you want that defense works in % right?
Be sure that the defense do go over 100

in game battler look for:
for physical damage

   damage = attacker.atk * 4 - self.def * 2 

change it to:

  atk_power = attacker.atk #you can change it any way you want like use VX "attacker.atk * 4" formula
 damage = atk_power - (atk_power * self.def/100)

since in VX theres no "Mag def" status, you will have to use defense for both.
so you can do this for mag damage

change:

    if damage > 0                                   # a positive number?
      damage += user.atk * 4 * obj.atk_f / 100      # Attack F of the user
      damage += user.spi * 2 * obj.spi_f / 100      # Spirit F of the user
      unless obj.ignore_defense                     # Except for ignore defense
        damage -= self.def * 2 * obj.atk_f / 100    # Attack F of the target
        damage -= self.spi * 1 * obj.spi_f / 100    # Spirit F of the target
      end
      damage = 0 if damage < 0                      # If negative, make 0
    elsif damage < 0                                # a negative number?
      damage -= user.atk * 4 * obj.atk_f / 100      # Attack F of the user
      damage -= user.spi * 2 * obj.spi_f / 100      # Spirit F of the user
    end

to:

    if damage > 0                                   # a positive number?
      atk_power = user.atk #you can too change the formula here
      mag_power = user.spi #you can too change the formula here
      damage += atk_power * obj.atk_f / 100      # Attack F of the user
      damage += mag_power * 2 * obj.spi_f / 100      # Spirit F of the user
      unless obj.ignore_defense                     # Except for ignore defense
        damage -= atk_power * self.def * obj.atk_f / 10000    # Attack F of the target
        damage -= mag_power * self.def * obj.spi_f / 10000   # Spirit F of the target
      end
      damage = 0 if damage < 0                      # If negative, make 0
    elsif damage < 0                                # a negative number?
      damage -= user.atk * 4 * obj.atk_f / 100      # Attack F of the user
      damage -= user.spi * 2 * obj.spi_f / 100      # Spirit F of the user
    end

Thanks!  I thought I looked there before, but I just didn't see it there.  I appreciate your help!
