Talk: Fallout: New Vegas combat

modifiers?

I've been trying to do some damage calculations, and although the article says damage modifiers are applied after the DT is subtracted by the damage, but does that mean any DT modifier is applied before that step? also, where are the "difficulty modifiers", and shouldn't there be modifiers for other parts of the body than just the head? --MoronicCinamun 23:16, March 28, 2011 (UTC)

Consumables

There are 3 Consumables that affect damage. They are Psycho, Yao guai meat, and Weapon binding ritual. When are these figured into the equation? Also, how is the fourth rank of the Camarader-E perk figured in? As a Perk, it would be in the Perk portion of the damage formula, but it provides a fixed bonus instead of a proportional bonus, which completely screws with the simplicity of the formula.

Testing

Doing damage tests right now. Boone is a test subject. My CHA is 7, which gives 35% increase to his DT. Difficulty: Very Hard. Perks: Better Criticals, Lord Death, Living Anatomy, Shotgun Surgeon. Gun skill: 100.

Ranged

Hunting rifle

(standard rounds) sneak attack critical head shot. While subject wears no armor I get matching results:

${\frac {(52+52*1.5)*2*2*1.01*1.05}{2}}=275.73$

Actual: 275

When subject wears armor (NCR Ranger combat armor set: 24 DT) the actual damage is finally matches to the calculated:

${\frac {(52+52*1.5-24*1.35)*2*2*1.01*1.05}{2}}=207.0096$

Actual: 206

Hunting shotgun

buckshot sneak attack critical head shot no armor:

${\frac {(10+10*1.5)*7*2*2*1.2*1.01*1.05}{2}}=445.41$

Actual: 445

buckshot sneak attack critical head shot on NCR Ranger combat armor:

${\frac {(10+10*1.5-(24*1.35-10))*7*2*2*1.2*1.01*1.05}{2}}=46.32264$

Actual: 70

buckshot head shot on NCR Ranger combat armor:

${\frac {max(0.2*10,10-(24*1.35-10))*7*2*1.2*1.01*1.05}{2}}=17.8164$

Actual: 14

slug sneak attack critical no armor head shot:

${\frac {(70+10*1.5)*2*2*1.01*1.05}{2}}=180.285$

Actual: 180

slug sneak attack critical head shot on NCR Ranger combat armor:

${\frac {(70+10*1.5-(24*1.35-10))*2*2*1.01*1.05}{2}}=132.7746$

Actual: 131

C-4 plastic explosive

with 36 skill, no armor:

$DAM_{skill=36}=250*({\frac {50+36*0.5}{100}})=170$

${\frac {170*1.01*1.05}{2}}=90.1425$

Actual: 90

On NCR Ranger combat armor set:

${\frac {(170-24*1.35)*1.01*1.05}{2}}=72.9624$

Actual: 73

As far as I've ferreted it out, the complete damage calc is here. I haven't tested for every single game scenario, mostly a few unarmed/melee scenarios left to check, but for the most part, this is correct. The Gunny 19:42, May 21, 2012 (UTC)

Hmm, looking at your formula. Have questions. I thought each projectile damage is reduced by DR/DT separately. What is AOE Damage, Object Effect Damage and Aid Damage Multiplier? Slider2k 22:49, May 21, 2012 (UTC)

I have problems in calculation only when armor is involved. Slider2k 23:44, May 21, 2012 (UTC)

It may suggest that armor on NPC in FONV has a slight DR component. Yet buckshot damage calculation on an armored subject with shotgun surgeon perk is still completely off. Slider2k 18:51, May 22, 2012 (UTC)

Slider, sorry I haven't kept up with this, been a bit busy. I would suggest some of your numbers may be off because of your target. I think you said you're using Boone. There may be DR scripts with him, I don't recall. If you're on PC, There's a great mod on nexus that Urtho made for me (just a lengthening of the existing testjoshweapons cell) that I use for testing. I can point you to the dl if you want to use that. It's a much better environment for testing. Also, catch me in chat if you want me to e-mail my damage calculator to you. I'm in the middle of updating it, though, so I'm not sure if it's fully functional (I might have an older copy around someplace). The Gunny 00:21, May 23, 2012 (UTC)

You're right! Numbers were off because of the target! I completely forgot about Companion Nerve (thanks to Living Anatomy not accounting that when showing DT). I've edited corrections in. Yet buckshot on the armor is still somewhat off. Slider2k 03:14, May 23, 2012 (UTC)

Accuracy

looking on wiki and dont see page asociated whit accuracy, not mentioned here or in other pages. We need page that have basic formulations. Ther need to be made clear description of accuracy in and outside of V.A.T.S. Starting whit limbs condition, weapon Sway, influance of croching and using Iron Sights (& alignment), weapon spread, Traits and Perks, chems. Is realy incredible you cant finde some basic info in wiki or even track them in multiple pages considering accuracy is most basic important thing you can posible have question abouth wen planing strategy. nEVER_BoRN
