As welcor said, you aren't going to get a patch to fit if you changed
almost any code. It just don't happen. Patch does a nice job of
protecting people from being lazy by saying "Oops, the file I'm patching
isn't what I'm expecting, so I'm not messing up their code. I'll give
them a .rej file so they can make sure things keep working."
No-one's goal is to make you feel like a moron, but we're not going to
code your mud for you on the list. saying "For me to understand it, it
has to correspond perfectly between the patch and my mud" simply tells
everyone that you {don't know how,are too lazy} to do it for yourself.
I've never looked at the coin patch mentioned, so I don't know how it's
doing things, but I do disagree that it's not trivial though.
There's no huge need to do anything drastic to huge sections of code,
since when it comes down to it it's mostly cosmetic.
If you just think in terms of a base currency, say, a penny, then
everything is just multiples of that. Do all the internal stuff ie
if(GET_GOLD(ch) < amount) { You cheapskate } in terms of this "base".
All you'll need to do is prettify the output... here's a tool to help
you with it though.
--- mailer code ---
#define COP_ELEC 100000 /* How many coppers per electrum piece */
#define COP_PLAT 10000 /* How many coppers per platinum piece */
#define COP_GOLD 1000 /* How many coppers per gold piece */
#define COP_SILV 100 /* How many coppers per silver piece */
/*
* Hold the calculated values of each type of coin.
* Makes it easier to check if you have a value of 0 for any of them.
*/
struct coin_struct {
unsigned int electrum;
unsigned int platinum;
unsigned int gold;
unsigned int silver;
unsigned int copper;
};
struct coin_struct *calc_money(unsigned int amount)
{
struct coin_struct *coins;
unsigned int tmp = amount;
CREATE(coins, struct coin_struct, 1);
coins->electrum = tmp / COP_ELEC;
tmp -= coins->electrum * COP_ELEC;
coins->platinum = tmp / COP_PLAT;
tmp -= coins->platinum * COP_PLAT;
coins->gold = tmp / COP_GOLD;
tmp -= coins->gold * COP_GOLD;
coins->silver = tmp / COP_SILV;
tmp -= coins->silver * COP_SILV;
coins->copper = tmp;
return(coins);
}
--- end mailer code ---
Then just change the places where you send_to_char() a coin amount to
call that with, say, calc_money(GET_GOLD(ch)) and display it from the
values returned. Some work will be needed in do_give and
perform_give_gold() but that's fairly trivial.
