User:Gozolo/Barter System

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:

fBarterBuyBase (default value = 1.55)

fBarterBuyMult (default value = -0.45)

fBarterSellBase (default value = 0.45)

fBarterSellMult (default value = 0.45)

Buying from a vendor formula:

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

Selling to a vendor formula:

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

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.

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

Selling to a vendor price will be 169.

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

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.
