Here is the correct gold calculation for repairing an item:
Code:
int nRecoverDurability = Math.Max(0, Item.Stats.Durability - Item.CurDurability);
if (nRecoverDurability == 0)
return;
byte Quality = ItemManipulation.GetQuality((int)Item.Stats.ID);
double QualityMultipier = 0;
switch (Quality)
{
case 9: QualityMultipier = 1.125; break;
case 8: QualityMultipier = 0.975; break;
case 7: QualityMultipier = 0.9; break;
case 6: QualityMultipier = 0.825; break;
default: QualityMultipier = 0.75; break;
}
int nRepairCost = 0;
if (Item.Item.ShopBuyPrice > 0)
nRepairCost = (int)Math.Ceiling((Item.Stats.ShopBuyPrice * nRecoverDurability / Item.Stats.Durability) * QualityMultipier);
nRepairCost = Math.Max(1, nRepairCost);
