I know that I can use a [x,y].max in the formula. But I want a minimum damage applied to ALL attacks as a percentage based on the attack-value-formula-part.

Let's say I have 100 attack, and the creature has 500 defense, then I still want to deal 20% of the attack-damage minimum. I also want the minimum percentage to be able to crit.

Formula: a.atk * 4 - b.def * 2

I cant extract the total a.attack from RPG::UsableItem::Damage. Basically I need the 100x4=400, 400 *20% = 80 damage. Then multiply 80 by the crit modifier (if any).

I found this:

http://forums.rpgmakerweb.com/index.php?/topic/27240-setting-a-minimum-damage-using-percentages/

But then I have to manually put it in every single damage formula... And the little script does not provide a minimum damage percentage.

Basically some automated form of:

[a.atk * 4 - b.def * 2, a.atk * 4 * 0.2].max

P.S.

I wasn't sure if this belongs here or in script support/request.

I would do it by rewriting the "Calculate Damage" method in Game_Battler, as such:

#-------------------------------------------------------------------------- # * Calculate Damage #-------------------------------------------------------------------------- def make_damage_value(user, item) value = item.damage.eval(user, self, $game_variables) ### Modification Begin if ((value <= (user.atk * 0.8)) and item.physical?) value = (user.atk * 0.8) elsif ((value <= (user.mat * 0.8)) and item.magical?) value = (user.mat * 0.8) end ### Modification End value *= item_element_rate(user, item) value *= pdr if item.physical? value *= mdr if item.magical? value *= rec if item.damage.recover? value = apply_critical(value) if @result.critical value = apply_variance(value, item.damage.variance) value = apply_guard(value) @result.make_damage(value.to_i, item) endIf you are using different formulae for skills so that the amount won't always be a.atk * 4 * 0.2 or a.mat * 4 * 0.2, then you're getting into much more complicated territory, and you'll either have to do the normal ".max" processing in each formula like you mentioned before, or request a script that breaks down each part of the formula line and evaluates it as two separate kernels.

Just place this in your scripts section somewhere. Crits works (along with misses and everything else).

class RPG::UsableItem::Damagealias_method:)min_auto_eval, :eval)def eval(a, b, v) damage = min_auto_eval(a, b, v) [damage, a.atk * 4 * 0.2].maxendendreplace a.atk * 4 * 0.2 with whatever you want the minimum to be.

Hope this helps. :)

Thanks guys. Both answers helped a lot. :)

class RPG::UsableItem::Damagealias_method:)min_auto_eval, :eval) def eval(a, b, v) damage = min_auto_eval(a, b, v) p "dmg: #{damage} dmg. min: #{[damage, a.atk * 2 * 0.2].max}" [damage, a.atk * 2 * 0.2].max endendIndeed works. But it causes problems when using magic-attacks. There is no reference here to the item-variable so you can't check the attack-type (magical vs physical/certain-hit)

This one:

Spoiler
class Game_Battler < Game_BattlerBase #-------------------------------------------------------------------------- # * Calculate Damage #-------------------------------------------------------------------------- def make_damage_value(user, item) value = item.damage.eval(user, self, $game_variables) ### Modification Begin if ((value <= (user.atk * 0.8)) and (item.physical? || item.certain?)) # Added code: || item.certain? value = (user.atk * 0.8) elsif ((value <= (user.mat * 0.8)) and item.magical?) value = (user.mat * 0.8) end ### Modification End value *= item_element_rate(user, item) value *= pdr if item.physical? value *= mdr if item.magical? value *= rec if item.damage.recover? value = apply_critical(value) if @result.critical value = apply_variance(value, item.damage.variance) value = apply_guard(value) @result.make_damage(value.to_i, item) endend
works for magical, physical and certain attack types. But it uses an overwrite (still good though).

Note: I tested this with a battle-test from the system > troops tab and both the player and the slimes had 999 defense.

Minor note: if you have an attack value of 1 then it will still be 0 due to the rounding. So you still need a [damage, 1].min line on top of it :p

I didn't think of magic attack lol. Glad I could help though.

I found a way to do it without an overwrite (using a game variable instead) and by combining both solutions:
