[3.14]

The whole 'effective range' thing isn't all that clear to me, and I don't think I'm the only one with this problem. So I cooked up a tiny program to make the math for you. Can't say if it's all correct - it's based on the info in the wiki alone.

Python source (will need Python 2.x, not sure it it's 3.x compatible):

Windows binary (py2exe):

Screen (Warning! Ugly Tkinter!):

Spoiler for Hiden:

If You like it/use it donate a bottle cap to any random, new player.

EDIT:
Links replaced, there was a small error and the displayed values where off by one.

EDIT2:
Now the accurate perk gives +30%, new links above.

Yay! Great. Gonna use your work for character planner, may I?

Interesting how much skill affects accuracy but i.e. 2 special point difference in PE effect is minor...

Good job, pal, very useful thing. Thanks a lot.
Now it's time for charity.

Use it as you will. It's MIT license.

If the wiki is true then PE only affects aimed shots, or if you have less then 5 of it (perception not wiki - silly English).

There was a small error, the value shown for range of 1 was really calculated for range=0. Links to a updated version are now in the first post.

Good job, this is very useful program if its reliable.
but the 'accurate' weapon trait aint modify anything for me at all. it may be a bug?
although PE, sharpshooter and scope only affects aimed shots. is it true? i'd be be glad if a dev have confirmed this! if true, i wont waste point on 'sharpshooter' perk or 'gain PE' (i have cause its very marginal.
btw its funny that scope helps almost nothing for those who have very good eyes (Pe 10 + sharpshooter) + 250 skill, even for aimed shots

My bad. It is a bug. Fixed it in a new version (links in the first post).

I'm not sure how the scoped perk works wit scoped x2. x3 and so on. Should it give +2 PE, +3PE... and so on?

Also if the Devs would be willing to share the burst mechanics formula I'd add that as well.

Scoped weapon perk only affects sight range, not hit chance. Also, weapon minimum strength affects hit chance as well.

Skill below 150:

baseHitChance = 0.95*(skill-50) + rangeModifier

Skill above 150:

baseHitChance = 95 + (skill-150)*4 + rangeModifier


The range modifier is given by:

Distance to target less than effectiveRange:

rangeModifier = 95*(effectiveRange - distanceToTarget)/effectiveRange

Distance to target greater than effectiveRange:

rangeModifier = 1000*(effectiveRange - distanceToTarget)/effectiveRange

And in your code you have:
        if distanceToTarget<effectiveRange:
            rangeModifier=95.0*(effectiveRange - distanceToTarget)/effectiveRange
        else:
            rangeModifier = 1000.0*(effectiveRange - distanceToTarget)/effectiveRange

if skill<150:
            baseHitChance = 0.95*(skill-50) + rangeModifier
            if perc<5:
                baseHitChance-=10
        else:

Are you sure about not strict comparisons in first cases?

[3.14]

No, not sure at all :]

[paragon]

I'm gonna do it opposite way xD

[3.14]

In the face of ambiguity, refuse the temptation to guess.

[paragon]

With weapon range 90 and skill 150 you have 95% at 61 hexes. I guess it's 1 hex away from right.

[Prosector]

Isn't something wrong with sharpshooter? if i test with 3 PE+sharpshooter, it gives worse result than 5 PE without sharpshooter.
Isn't sharpshooter supposed to count as 2 PE?

My bad. Here's a fixed version, but the fix was made on a phone, so it may be wrong.

I'll post a exe when I'll make one (when/if I get home).

I'm starting to regret not putting it all on github.
