[Trigger] Trying to detect negative armor

[Tal'Rarity]

Does anyone know the correct equation to reverse -20 armor so 250 damage is 250? The damage type is 100% and the armor constant is 0.06.

-20 Armor are +71% dmg (0,7098) on Normal setup. (The max bonus you gain from negative).
-> Results in a multiplier of 1,71.
-------------------
2 - 0,94^(-20) = -1.44 (this is somehow wrong), cause 2^(-2) = 1/(2^2)
2 - 0.94^(20) = 1.71

What's the purpose of dealing "physical" damage if the armor plays no role?

Negative armor is forced to play a role due to hardcoded.

Negative armor is capped so it can only detect up to a certain amount.

Negative armor as a function of damage dealt, damage taken and armor constant requires the use of logarithm. JASS lacks native logarithm support, so a logarithm library is needed.

function calculateArmorFactor takes real armor returns real
    if armor >= 0 then
        return 1 - (0.06*armor / (1 + 0.06*armor))
    endif
    return 2-Pow(0.94, -armor)
endfunction

Following that equation, you just have to divide your resulting value by the returned value from that.
(I know WC3 armors are integers, but that doesnt mean that you dont see the use of having it as reals.)

I also do not give a damn about the armor limit

However, you do have to get the armor value first to apply this function.

WC3 armor is not an integer. It is only rouded so for the UI. Individual points of agility will give fractional units of armor under standard gameplay constant settings.

In any case... it is a real now.
