I handled this with a structure which includes the short name of the currency, the long name, the value against standard (currency 0 is considered the world standard), and a number of fields which are used by create_money to give adequate descriptions. > I defined a GET_MONEY(ch, i) (ch->points.gold[i]) Similar, though as I said, I changed most everything from gold to money.

Show player is not changed for me, but that's not a really vital command, and since stat lists it properly, I'm not concerned. > I was really suprised that the hacks to shop.c were as easy as they were.

I use some math and a macro everywhere I need conversion. No extra function. All shopkeepers display prices, quote values, give and take money in the proper format for the region. The shopkeepers themselves keep money on them in the world standard format, and store it like GET_GOLD, etc. The only thing that I do is convert the money paid for an item into the right format. To the user it looks like everyone has different prices all over the world. > About all I need to do now if finish changing all the GET_GOLD calls to > GET_MONEY, and make the db load of mobs take the set gold value they should > have and change it to whatever the regional currency type is. I've done this. All GET_GOLD calls are changed with the exception of the ones that deal with mob loading/saving/editing, and shopkeeper upkeep. It's all GET_MONEY(ch, i) other than that. Banking is handled similarily to shopkeepers, though it's merely an established fact that the bank runs on world standard currency, and all local currency is converted to an equivalent amount. 5% is charged for all bank withdrawls, as it serves as the moneychanging service for the world. For handling currency exchange, drop, etc I have a command which sets the player's currently handled currency to whatever they choose. So if they set it to "eggs" and say drop 5000 coins, they drop a pile of 5000 eggs, assuming they have that many of that currency. I'm sure I could have done it just as a part of the drop, etc commands, but it seemed to be fraught with peril, so I just did it this way. :) Anyway, that's my post for the archives in case anyone looks up money or coins or currency or whatever in the future! -Mathew -- +---------------------------------------------------------------+ | FAQ: http://qsilver.queensu.ca/~fletchra/Circle/list-faq.html | | Archives: http://post.queensu.ca/listserv/wwwarch/circle.html | | Newbie List: http://groups.yahoo.com/group/circle-newbies/ | +---------------------------------------------------------------+
