I know that each gun has a different % modifier for hit chance, but does anyone know the formula to calculate how much of BG, SG and NRG skills for each amount of PE to have max hit %? It seems to be a standard for big gunners to go for 95% on RL at max distance, not sure if there's similar things for other skills. I guess to make it complete, we could put throwing % in here too, but I feel like someone told me that was based on ST.

i know for BG 6pe and 160bg is about optimal for full use of avenger but im not sure of the exact forumla

the base to hit% is your skill.
- add (PE-2)x16% for all long range weapons(i.e. with a range of 26+) that were already implemented in FO 1, or are upgrades of these weapons, (PE-2)x8% for the rest.
- The scoped hunting rifle gets (PE-2)x20% instead of the x16% if you shoot at a target that is at least 5 hexes away, or no PE-bonus at all for closer enemies.
- It seems the other newly implemented long range weapons in FO 2 are bugged, they only get the (PE-2)x8% while all long range weapons from FO 1 had the (PE-2)x16%.
- deduct 4% per hex between you and your target.
- deduct 20% for each point of ST missing to use the weapon properly.
- accurate weapons get a 20% bonus. All shotguns also get that. Guess it's easier to hit because of the spread.
- deduct the AC of your target after modifying it with the used ammo type.
- darkness, obstructions in the line of fire, and several perks also give boni or mali, which I do not know.
- After all the above modifiers your chance to hit CAN get below 0, but never above 95%.

http://fonlinedocs.netii.net/tohit2.c
A pseudocode version of the to-hit algorithm (it's too long to call it "formula"), as reversed from the FO2 executable.
The notion of long rangedness, scope rangedness and accuracy is based on the weapon perk, a hidden property of weapon present in FO2 (proto offset 0x65).
The following are not implemented in Fonline, due to engine constrains: light level bonus/malus (and hence Night Sight weapon perk), multihex critters blocking the line of fire, difficulty settings (obviously).
-
if (attack_is_ranged) tohit+=location_penalty; // which is negative
else tohit+=location_penalty/2;
What is this location penalty?
if (attacker_is_player) dist-=(perception-2)*distmod1; // player nerfed
else dist-=perception*distmod1;
Which is the case in FOnline?

Are my calculations correct? I want to know how much small gun skill I need to be able to get 95% to hit with a regular shot at maximum range with for example a .223 pistol.
If this is the formula: to hit%= skill-(PE-2)*8-4*distance-(AC target +AC ammo modifier)
Than to use a .223 pistol at 30 hexes, I have 6 PE, against a target with 10 AC is (My skill in sg is X):
if 223 pistol is not considered a long range weapon:
95= X+(PE-2)*8-4*30-(10-20) --->X=95-4*8+120-10=173
and if 223 pistol is considerd a long range weapon (+26 hexes):
X=95-4*16+120-10=141
Is this correct or is my math skills corrupt? I need 141 to be able to hit at max range with a .223 pistol?
-
.223 is not a long range weapon.

remember that .223 ammo has -20 AC

.223 is not a long range weapon.
Yes I did not think it was, I was just did not know how it was implemented. The Bob wrote " - add (PE-2)x16% for all long range weapons(i.e. with a range of 26+) that were already implemented in FO 1, or are upgrades of these weapons, (PE-2)x8% for the rest."
And since .223 pistol has a range of 30 it might be in that category?
remember that .223 ammo has -20 AC
I think I did, it is the -20 in the ...*30-(10-20)...
Still I´m not sure if I have made the write calculations.
Anyone who might be able to check it out? Hmmm, why don´t I do that myself :D

FYI bob darkness doesn't affect anything it's broken.

1. Eyes, head etc. penalty.
2. Yes.

It can't be "broken" as it was never implemented server-side in the first place.

- deduct 20% for each point of ST missing to use the weapon properly.
so if I have a strength of only 4 i get a possible max of 120% deduction? (for those requiring 10) .......

In theory, but the highest ST required is 7 by some of the big guns. So with 1 ST, you could encounter this, but I don't know anyone that's made a build with 1 ST and been anywhere near successful.

Is this still accurate? I wonder whats the formula

It hasn't been changed, so this is accurate.

I made the same calculation for .223 pistol for 30 range and yet i got different result... tell me where am I wrong (I took 15 AC)
95 = X + (4)*8-4*30 - 15
-X = 32-120-15-95
-X = -198
X = 198% skill needed to have 95% with .223 at 30 hex wat ;D
This cant be true...I'll check but I doubt it
-
Don't forget the .223 ammo's AC mod. It's -20 and the enemy's 15 AC, so his AC will count as 0.
6 PE, .223 Pistol, no onehander perk, 30 hex range, your strenght is enough, no AC for the enemy - the unaimed attack needs 183% SG for 95% tohit at unaimed shot. If the enemy has 35 AC, so after the ammunition modifier it will be 15, then yes - you will need 198%.

If I'm not mistaken, you should need less skill with .223 pistol. Since it fires from over 26 hexes, it is a long range gun and the perception modifier is multiplied by 16 instead of 8.
My own question: how would one find out if a weapon has an accurate perk?
-
Weapons perks are given in weapon's description (IG). .223 pistol have penetrate and not Long Range, so it's *16% but *8%.
