What is a formula for dmg including treshold?

How does threshold  work? I see almost all ammo got about -50, -30, -20 DT. So that ammo is deacreasing DT always to 0? Why so high numbers?

From what I understand ammo that negates gives negative DT is armor piercing.  What it does it negate a certain value from the targets armor, and if the target's armor threshold is above the negative DT incurred by your ammo they'll still have SOME protection. If their armors DT is lower than the value your ammo negates, its like their wearing nothing.

Well nobody is able to have more than 22-24 dt so why -30 dt for example or -50???

I can make an assumption

Lets say s1 hit u with 100 dmg

Ur armor has 10 th and 50% armor resistance

Dmg would be:
100*0.5 = 50
50-10 = 40
So amount of absorbed damage by armor is 60 of basic damage

And from this number will be subtracted bullet penetration
Not from clear TH but from % of resistance as well

In that case high bullet penetration make sense

I can easily be wrong =)

14 Normal dt from CA. + Psycho = 24 normal dt. + adrienaline rush = 28 normal dt.
Then Add PA ontop of that and u got like 35 normal dt.
Or even APA and u got 41 normal DT?

Use ur Primary school math skills.. xD

Edit: On a side note, Maybe devs were just newbs who mistaken DT for DR ?

Dmg would be:
100*0.5 = 50
50-10 = 40

i thought it calculates by this:
100-10 = 90
90*0,5=45

DR comes first?

[wojciech]

Gauss ammo got -100 dt so?
Avenger ammo got -90 dt
Drugonov ammo got  -66dt
14mm ammo got - 66 dt
9 mm ap ammo got -90 dt
Why so high numbers? Even with 50 dt on You its still too small amount comapring to those numbers...

bump.. Still need information. I need to know how calculate dmg with that threshold.

I am curious about this too.

Look at 9mm JHP
DR 28
DT 65
DMG 2/1

With the typical fallout formula, and a Mauser you get:
min dmg:  ((18*2/1) -65)*(100-28)/100=-20.88
max dmg:((22*2/1)-65)*(100-28)/100=-15.12

Can't be right. DT mod must be a percentage, just like DR.

Lets wait for gejm master he will tell us the truth

Explains AC, DT and DR in terms of Armour, but it correlates with ammo.

AC reduces chance of getting hit. Not really part of damage formula.

DT minuses the incoming damage.

DR reduces damage as % after damage passed through DT.

DamageMod (DM) also changes the damage of the gun. Not armour parameter but still counts.

I'm guessing the way they do it is (BaseDamage * DM - DT) * (100 - DR)/100 to give final damage output. I if it comes out that final output to be 1 or less (even -ve) then damage is always 1 from what I can tell from NPC hits. Of course ammo modifies it also and would mean DT and DR would increase or decrease on the armour. I'm guessing DT can go -ve and DR will only hit as low as 0%. Problem is I don't know what armour bypass is. Does armour bypass reduces DT and/or DR by a %?

E.G.

Armour Has: 5/55% (5 DT / 55 DR)
Ammo Has: 30 DT / -30 DR / 2/1 DM
Gun does 100hp (ignoring dm range)

Final damage:
(100*2/1 - (5 + 30)) * (100 - (55-30))/100
= 124 (rounded)
* Keep in mind if value is 1 or less it will always be 1hp damage.

** I could be horribly wrong and ammo DT DR modifiers are % modifiers of respective properties rather than simple values. Since DT of -100 on ammo would make the damage more than the max intended value. So probably ammo modifiers are ALL %. That is, -100 DT and -100 DR ammo would mean the gun does base damage * DM regardless of what armour they're wearing, since all of the resists will be negated.

(100*2/1 - (5 + 5*0.3)) * (100 - (55 - 55*0.3))/100
= 119(rounded)
