RMMV Damage Formula - ideas and help

How would one go around to setting up a basic attack, that does more damage based on how much HP the user has lost?

I'm trying to do some skill that is quite the same of your, did you figured out how to heal/buff all party members? I didn't find a reply in here about this, or maybe i'm blind lol.

I'm looking to do 2 "limit" skills that deals aoe damage to enemy, one as bonus heal the party and remove debuffs, and the other give bonus damage of 1 element....

Someone know how to apply heal/buff to entire party? I just need an example so i can figure out other kind of similar "limit" skill

You could add in something like atk * (1 - (a.hp/a.mhp)) to get that effect. It deals damage based on a percentage of their current health over their max health. Alternatively, if you wanted to do something like deal 2 damage per each HP lost, you would do 2 * (a.mhp - a.hp). 

@VHStapes, damage must be the last thing in the formula

I've been trying to figure out the command for doing this, as well. My only difference is that I would want it to heal the entire party instead of every OTHER member, but I figure the way to do it would be similar. Any ideas?

If I'm right, I think it would need a for loop to target all the actors. I just don't know what the code would be exactly.


Something like


for(var i = 0; i < $gameParty.members.length(); i++) { $gameParty.members(i).hp + x; $gameParty.members(i).removeBuff };


You might want to replace:


$gameParty.member(i)


with


BattleManager.actor(i)


Of course you'd need some code in there for the actual damage and healing calculations.


Also, I wouldn't expect to plug this in and have it work as I am a Javascript n00b, but I'm sure someone can clean it up from here.

How do I make a damage formula that scales off of the enemies missing health?

I'm trying to copy Riven's Wind Slash skill from League of Legends.

If you want to make exactly this skill (exept for the level of the skill), it should look at something like this:

y=(1-Math.max((b.hp/b.mhp),0.25));r=120+(a.atk*0.6);r=Math.round(r*(2.67*y+1));rWith the y as the % of target's missing health with a cap for the 75%, first part r as the minimum physical damages increased by the atk of the user (or the AD in lol), and second part r as the multiplication of the target's missing health percentage.

a.add_state(13); 30 + a.atk + (a.atk * .4)

a = the user of the skill

b = the target of the skill (enemy - bear in mind that this is from the point of view of the user.  So an 'enemy' of the Demon Lord is your hero.)

* = multiplication sign.  

the main stats use the normal abbreviation.  So

a.atk * 4 - b.def * 2

means that you have the attack value of the user multiplied by 4, from which you deduct (the minus sign) the defence of the target, times 2.  The resulting number is how much damage is inflicted.

There are other things, but if you are a complete newbie, I think those are the main things to remember.  Once you've worked that out, it is simpler to follow what is going on.

Thanks! Do you think you could help me with another one?

I'm trying to recreate Garen's Decisive Strike from League of Legends. I find that LoL has a lot of interesting skills that I can pull ideas from. >_<

I'm trying to have the skill remove negative states from Garen while also adding a speed buff to him. On top of that I'm trying to make the skill add a silence state to the enemy.

a.add_state(13); 30 + a.atk + (a.atk * .4)This is what I currently have but it seems to do no damage. I can inflict the silence fine but need help with removing negative states as well as adding the speed state.

Use a.addState

Hey guys,

I'm trying to create a skill which will inflict state X at a 50% chance rate, ONLY when the enemy's darkness element rate is X.  Any help?

I'm trying to have a skill with a guaranteed critical. In VX ACE you could use: b.result.critical = true

This doesn't work in MV and I can't work out why.

Also is it possible to have a crit apply a an affect to the enemy or myself

I finally figured this one out. :D For those of you wondering how to do this, try:

b.result().critical = true 



With that in mind, you could do something like: 

if (b.result().critical) {a.addState(x); y} else {y}Here you would replace x with your state ID and y with your base damage formula. Also, a.addState(x) would add a state to the user, whereas you could do b.addState(x) to add a state to the victim in the case of a crit.

Note that I just tested this with Yanfly's new Damage Core plugin and that plugin seems to prevent this from working, probably because it changes the order that damage is calculated.

b.elementRate(Y)>X?Math.random()>0.5?a.addState(Z):0:0;with

Y: ID of darkness element

X: Darkness element rate (with 1=100%, 2=200%, 0.5=50%, etc...)

Z: Id of state you want to add
