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

The buying price can't be lower than the item's 'value' as well as the selling price can't be higher than the item's 'value'.

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.
