Best Practices

// Consumables: High stock, low value
Health Potion: MaxStock = 50, Price = 10

// Equipment: Low stock, high value
Legendary Sword: MaxStock = 1, Price = 5000

// Infinite vendor for basic supplies
Config.bHasStock = false  // Tutorial merchant

// Don't set MaxStock too low for consumables
Health Potion: MaxStock = 2  // Players will get frustrated

// Don't make everything infinite
Config.bHasStock = false  // Removes sense of scarcity

// Use market fees for taxes/economy sinks
Config.MarketFeePercent = 5.0  // 5% transaction tax

// Use buyback % to prevent exploit loops
Config.BuybackPercent = 40.0  // Buy at 40%, sell at 100%

// Override prices for special items
RareGem: UnitPriceOverride = 999.0  // Premium pricing

// Don't allow 100% buyback (exploit)
Config.BuybackPercent = 100.0  // Buy/sell loop for free money!

// Don't make fees too high
Config.MarketFeePercent = 50.0  // Players will avoid vendor

// General goods: Enable replenishment
Config.bReplenishOnBuyback = true

// Economy sinks: Disable for trash items
Broken_Gear: ReplenishMode = NeverReplenish

// Mixed strategy: Override per item
Valuable_Ore: ReplenishMode = AlwaysReplenish
Vendor_Trash: ReplenishMode = NeverReplenish

// Don't replenish quest items
Quest_Token: ReplenishMode = AlwaysReplenish  // Breaks quest flow

// Don't sink everything
Config.bReplenishOnBuyback = false  // Players can't trade with each other

// Themed merchants
Blacksmith: BuyList = [Ore, Metal, Broken_Weapons]
Alchemist: BuyList = [Herbs, Reagents, Potions]
Fence: BuyList = [Stolen_Goods, Contraband]

// Use BuysAnything for general stores
Config.bBuysAnything = true  // Convenience merchant

// Don't mix conflicting settings
Config.bBuysAnything = true
Config.bHasBuyList = true  // BuyList is ignored!

// Don't leave BuyList empty with bHasBuyList
Config.bHasBuyList = true
BuyList = []  // Merchant won't buy anything

// Daily restock via cron
UMerchantSubsystem* MerchantSys = World->GetSubsystem<UMerchantSubsystem>();
int32 Restocked = MerchantSys->RestockAllMerchants();

// Quest-triggered restock
SpecificMerchant->RestockNow();

// Don't expose RestockNow to players
// It's admin-only for a reason
