Editing User:Gozolo/Barter System

I'm new to 'wiki' CMS and don't know how to submit this text properly, but I made a little investigation on how barter system works in Fallout 3, so if a moderator finds it useful it can be added to the site. Meanwhile I'll post it here.

There are 4 parameters that effect the result of the price in the barter system. 2 for the buying prices and 2 for the selling prices.

!!! The skillcheck is based ONLY on the Player's 'barter' skill. Vendor's 'barter' skill has no effect on a price.


Parameters:

<pre>fBarterBuyBase (default value = 1.55)

fBarterBuyMult (default value = -0.45)

fBarterSellBase (default value = 0.45)

fBarterSellMult (default value = 0.45)</pre>


Buying from a vendor formula:

<pre>Price = ( 'Item Value' * fBarterBuyBase ) + ( 'Item Value' * 'Skill' * fBarterBuyMult / 100 )</pre>


Selling to a vendor formula:

<pre>Price = ( 'Item Value' * fBarterSellBase ) + ( 'Item Value' * 'Skill' * fBarterSellMult / 100 )</pre>


Examples:

As an example I'll take 'Ol' Painless' Hunting Rifle, which has a value '250' with default barter parameters considering that Player's 'barter' skill is 50.


Buying from a vendor price will be 331.

<pre>Price = ( 250 * 1.55 ) + ( 250 * 50 * (-0.45) / 100 ) = 387.5 - 56.25 = 331.25</pre>


Selling to a vendor price will be 169.

<pre>Price = ( 250 * 0.45 ) + ( 250 * 50 * 0.45 / 100 ) = 112.5 + 56.25 = 168.75</pre>


There are some other parameters, but my only guess is that they remain from the Oblivion and are unused in the Fallout 3 system.

Thanks for your attention. I hope it'll help.
