Calculation of "to Hit"-Model

[TMaekler]

Hi,

was wondering about the way the soldier stats affect the to Hit values. Let's start with an example:

70% Hit chance / 50% Crit
According to the description on Ufopedia the 70% Hit Range would lead to a 20% Miss, 20% Grease and 60% Hit chance.
The 50% Crit would divide the Hit and Grease chance and convert them into:
- 60% Hit to 30% Crit and 30% Hit
- 20% Grease to 10% Hit and 10% Grease
- the 20% Miss would be unaffected
Which would lead to a total of 20% Miss, 10% Grease, 40% Hit and 30% Crit.

So far so good. But how do soldier stats affect this values? If a soldier for example has 15 dodge and 5 defense at what point would those values come into effect and change the effects of the RNG?

a) directly added to the RNG: 15 dodge + 5 defense = RNG + 20
That would lead to 40% Miss, 10% Grease, 40% Hit and 10% Crit.

b) decreasing the Hit Chance: 70% to 50%.
That would lead to 40% Miss, 10% Grease, 30% Hit and 20% Crit.

So with the second model we would have more crit chance than in the first. But which is implemented in LW2?

Defence applies to the initial hit chance, bringing it to 65% or 45 Hit / 20 Graze / 35 Miss.

Dodge then applies last in the same way that Critical Chance does, just in reverse - so it goes:

Crit applies: 23% Crit, 32% Hit, 10% Graze, 35% Miss

->

Dodge applies: 20% Crit, 30% Hit, 13% Graze, 37% Miss

(Math done loosely, but I think it's right - note that Dodge can reduce a Graze to a miss, even though Crit can't turn a miss into a Graze.)

Defence applies to the initial hit chance, bringing it to 65% or 45 Hit / 20 Graze / 35 Miss.

I thought Graze brings it to 55 Hit / 20 Graze / 25 Miss (the 10 Graze go + and - 10 around the 65).

Dodge then applies last in the same way that Critical Chance does, just in reverse...

So dodge is calculated last after Crit has applied; not that Dodge and Crit are summed up before applying?!?

Thanx

I thought Graze brings it to 55 Hit / 20 Graze / 25 Miss (the 10 Graze go + and - 10 around the 65).

Whoops, that was a mistake on my part - that is correct.

And yes, dodge is applied separately after critical chance.
