[Spell] How to create a spell with ratio armor

[Łapin Viktus]

I want to create a spell with ratio armor for my hero tank, may I put his value of armor in one variable? Or is needed a script? And how make it?


Thank you for help,

What do you mean when you say "ratio armor"?

What do you mean when you say "ratio armor"?

Maybe he means getting a percentage of a unit's armor as a bonus to his spell damage

 

[Łapin Viktus]

Yes that's it, to inflict damages with a spell according to the armor of the spellcaster.

You have to be able to detect the armor of the unit somehow, and there's no quick'n'easy way to do that. You could damage it for a certain amount of damage and calculate its armor based on how much damage it took.

----------

Tu peux pas le faire de maniere facile. Y'a pas de fonctions de base pour ca, faut que tu fasses un systeme ou tu infliges des degats fixes a ton unite et tu calcule l'armure basee sur la difference.

OK, then I make what you have say down here, after I do cast the spell?

@crabas_sakti I apologize crabas, I gave you the wrong damage reduction formula.

I thought damage reduction was (1-armorreduction)^armor

If we follow @Dr Super Good 's damage reduction formula, we would have

For positive Armor, damage reduction =((armor)*0.06)/(1+0.06*(armor))

So, if we deal 100 chaos damage to our unit, and it takes y damage, we have

y = 100 * (1 - (z * k)/(1+ (z * k)))

where z is your armor and k is 0.06, the reduction constant

y/100 = 1 - ((zk)/1+zk)

y/100 - 1 = - 1/((1/zk) + 1)

((y/100) - 1) ((1/zk) + 1) = - 1

(1/zk) ((y/100) - 1) = - y/100

1/z = k((- y/100)/(y/100 - 1))

z = 1 / (k((- y/100)/(y/100 - 1)))

Which would be your armor. If you were doing the triggers as I told you beforehand, erase them, here's the fresh (and hopefully more correct) way:

Event - whatever event you want to check the armor for


Actions

Set unitCheckUnit = the unit you want to check armor for

Set realCurrLife = current life of CheckUnit
save the current life of the checked unit

Set life of CheckUnit to (Life of CheckUnit + 100)
add some hp to the checked unit so it doesn't die

Set realy = current life of CheckUnit

Cause (some dummy unit) to damage CheckUnit for 100 chaos damage

Set realy = realy - current life of CheckUnit
check the damage really taken by the unit after we have dealt it 100 chaos damage
(y will be some value between 0 and 100)
ONLY WORKS WITH POSITIVE ARMOR VALUES

Set realArmor = 1 / ( ( 0.06 * ( - realy / 100 ) ) / ( ( realy / 100 ) - 1 ) )
We calculate the armor using the formula

Set life of CheckUnit to realCurrLife
Give our unit it's original life value back


Again, many apologies for my first false statement. Confused the armor system with another game I play.

This should be correct.

Convert realArmor to an integer if needed, retrieve your armor value.

Cheers!


PS; this should also only work for positive armor values.

Yep. Just put your unit casting the spell as the event, run the actions I listed, then the variable realArmor holds your armor, which you can do whatever you want with.

(though I did not test it since I do not have access to the world editor right now, but this should technically work, if you have any issues with that do tell)

Also, if you plan having negative armor values in your game, (through debuffs for example) just this trigger won't suffice.

Cheers!

Example of spell with a ratio of armor. I changed the defensive multiplier to 0.01 in my map...

It works, great thank you. I made my trigger like that. I skip "Set unitCheckUnit = the unites you want to check armor for" because I already have him on another trigger which names the unity. (The damages was just for test )

Ok, great. Although, from what I can see, your calculations do not calculate armor, but rather some multiple of it, since your constant is 0.01 and intended is 0.06. But regardless, good job!

 

[Łapin Viktus]

Yes, because I changed the defensive multiplier to 0.01. ^^
