Code clan hall/castle merchant transaction discount

[K9gash]

Hello everyone, here's a simple and useful idea for any type of server.

 

This code applies a discount when a player makes a purchase inside a clan’s castle or clan hall, offering a benefit to clan members who own a castle or clan hall.

Important: Merchant transactions must be handled through multisell, not buylist. The discount is directly applied within the multisell, so the price shown is already reduced.

 

"For example, if a scroll costs 1000 Adena and you set a 20% discount in the config, the final price when purchasing inside a castle or clan hall will be 800 Adena."

 

This code is developed on the public aCis 401 revision.

 

public static int CLAN_BASE_OWNERSHIP_MERCHANT_DISCOUNT;
CLAN_BASE_OWNERSHIP_MERCHANT_DISCOUNT = clans.getProperty("ClanBaseOwnershipMechantDiscount", 20);

# If clan owns a clan hall or castle, all members have a discount of X% at merchant transactions (multisell).
# Discount applies only inside the base (castle or clan hall).
ClanBaseOwnershipMechantDiscount = 20
