Code:

// Edited Merkur  03/12

	Mob* tmp = entity_list.GetMob(mp->npcid);
	if (tmp != 0)
		merchantid=tmp->CastToNPC()->MerchantType;
	else 
		break;
	uint16 item_nr = database.GetMerchantData(merchantid, mp->itemslot+1);
	if (item_nr == 0)
		break;
	Item_Struct* item = database.GetItem(item_nr);				
	APPLAYER* outapp = new APPLAYER(OP_ShopPlayerBuy, sizeof(Merchant_Purchase_Struct));

	mpo->unknown003 = 0x00;
	mpo->unknown004 = 0x00; 
	mpo->unknown005 = 0x00;
	// well i don't know how to calculate merchant prices exact, but *12 seems pretty near so it will do for now -Merkur
	mpo->itemcost = item->cost*mp->quantity*12;					
	cout &lt;&lt; "taking " &lt;&lt; item->cost*mp->quantity*12 &lt;&lt; " copper from " &lt;&lt; name &lt;&lt; "." &lt;&lt; endl;

	Save();

	break;
						}

struct:

Code:

struct Merchant_Purchase_Struct {
/*000*/	int16	npcid;			// Merchant NPC's entity id
/*004*/	int16	playerid;		// Player's entity id
/*008*/	int8	itemslot;
		int8	IsSold;		// Already sold
/*009*/	int8	unknown001;	// always 0x0b, 0x7c, 0x00 ??
/*009*/	int8	unknown002;
/*013*/	int8	quantity;		// Qty - when used in Merchant_Purchase_Struct
		int8	unknown003;
		int8	unknown004;
		int8	unknown005;
		sint32  itemcost;

Good job Merkur, you're a excellent coder =).

Great job on fixing the merchant code!
Now I can finally use 2.4 (with the next beta at least)

Have you also fixed the bug with purchasing stackable items? (they default to 0 items in the stack no matter how many you choose)
