Yanfly Engine Plugins is a plugin library made for RPG Maker MV, a wonderful piece of software to help you make that role playing game of your dreams. The formula I'm using is: float realDamage = SkillDmg. BaseDamage / (BaseDamage + Defense) The results are good, the damage gets bigger if the defense gets lower and it doesn't exponentially go up because of the division between (BaseDamage + Defense). Lets say I have a sword with 1.0 attack speed that deals 50 damage.
Something I've often toyed with aside from my own game FateStone was the idea of re-creating a Dungeons & Dragons campaign in something like RPG Maker. Seems easy right? You've got dungeons, monsters, characters all there and ready to go! However, the big hurdle is quite simply that the way combat works does not overlap. Like at all. RPG Maker's combat calculations are more inspired by Final Fantasy or Dragon Quest than anything you'd find in a Pen & Paper RPG tome. So I recently put my mind to work on figuring out how exactly you would be able to bring a d20 or D&D Style of combat to a RPG Maker game.
Now take in mind that this is a very basic version of what I started working with. While I have started working on versions to incorporate all the different D&D ability scores, I haven't hammered out all the nitty gritty of using them. So for now I strictly went for Attack Roll (Attack) vs AC (Defense) and Spell Attack (Magic Attack) vs Saving Throw (Magic Defense).
First is the dice roll:
1dX = Math.randomInt(X)+1
Rpg Maker Mv Damage Formula Cheat
YdX = Math.randomInt((X*Y), Y) + 1
For the YdX formula, it's important to note that you'll be setting the range of the random numbers, when it says X*Y you should replace that with the actual value of X * Y. In other words, for 3d6 don't put (6 * 3) just put (18). These formulas will be used for everything from determining the attack to the damage, so they are pretty much the cornerstone of this whole thing. But another important one would be how to you get the Ability Modifier from the Ability Score. For that you'll want to use the following calculation:
Math.Floor((A – 10)/2) = M
A = Ability Score. M = Ability Modifier.
In simple terms, you subtract 10 from the Score, divide that by 2 and round down (because you always round down in D&D) and that will give you the modifier. So an Attack (Strength) of 14 would result in a modifier of 2.
So how would this work for an actual skill? Well, let's take a look at one. First, you'll want to set the Skill in RPG Maker to be a ‘Certain Hit'. We are just going to skip the whole Accuracy/Evade cycle of the attack in favor of our own math. Then our damage formula will look something like this:
If (b.def <= (Math.randomInt(20) + 1 + (Math.Floor((a.atk – 10)/2) + (Math.Floor(a.lvl / 2)) )) Math.random((X*Y), X) + 1 + (MOD – Math.Floor(a.level/2)); else 0
Kind of crazy, right? Let's break it down. Shader model 2.0 for farming simulator 2011 free dowland.
If (b.def <=: This First bit is essentially starting an ‘If-then' clause that says if the following math results in something equal to or higher than our target's defense (AC).
(Math.randomInt(20) + 1: This is our d20 roll.
+ (Math.Floor((a.atk – 10)/2): This is adding our attack modifier
+ (Math.Floor(a.lvl / 2)) )): This adds half our level to the math and finishes our If condition. So it's a random number between 1-20, plus the modifier, plus half our level.
Math.random((X*Y), X) + 1 + (Math.Floor((a.atk – 10)/2)); This part is our damage calculation. Essentially, do this much damage (a random XdY dice amount) plus our Attack modifier damage.
else 0 And if the math DIDN'T equal or beat the Target's Defense(AC), then deal zero damage due to it being a miss.
To summarize, the formula is basically:
If (Target AC) <= 1d20 + Attack Modifier + Half Level; Deal XdY + Attack Modifier damage; else deal no damage.
Naturally, you can probably imagine how this basic formula can be applied to a lot of different things. It forms the basic idea for skill checks, saving throws, and pretty much any Difficulty Check based roll. You could replace the target defense with a d20 roll on the enemy side as well and have an opposed check.
As I said at the top, this isn't perfect. It doesn't quite yet take into account D&D's Ability Scores, which I'm still working on. Mostly just stuck on thinking of a way to make the Target Defense side of things work when b.def would simply be their Constitution score or something.
If I ever figure out a good solution to it, I will let you know.
In the mean time, you might find the following plug ins for RPG Maker MV to be handy when it comes to recreating the D&D experience:
