!! This file may be copied, modified and distributed freely, so long
4
!! as this notice remains. If it is modified, I ask that you change
5

6

7
!! long as you give me credit somewhere.
9
!! This is `money.h', an Inform header file that simulates
10
!! money. It is reasonably simple (I hope!) from your point of view
11
!! (that is, the point of view of you, the person including this
12
!! file!). Nevertheless, it needs some clarification:
14
!! * You need a number of objects of class MetaMoneyClass. I'm not
15
!! sure what exactly to call these -- in America, they would be
16
!! dollars and cents. The must have value, sing_name, plur_name,
17
!! sing and plur properties.
18
!! * All coins and bills to be used must also be defined, of class
19
!! MoneyClass. They too must have value, sing_name, plur_name, sing
20
!! and plur properties.
21
!! * You must define a number of constants:
23
!! 1. MONEY_TOTAL: Total the money if it's in the player's possession
24
!! 2. MONEY_TOTAL_ON_GROUND: Total the money even if it's not in the
25
!! player's possession.
26
!! 3. MONEY_SHOW: If the money is being totaled, show
27
!! the individual coins and bills.
28
!! 4. MONEY_SHOW_ON_GROUND: Same as above, but applies to the
29
!! ground (not in the player's possession.)
30
!! 5. MONEY_TALL_LIST: Show a tall list of the money if it's
33
!! * Read the example file, `greenbacks.inf'. Hopefully this file
34
!! should make everything absolutely clear. If not, please write me!
35
!! * By default, there are 25 dynamically creatable pieces of
36
!! money. If this is not enough, change the definition of MoneyClass.
37
!! -- BUGS! BUGS! BUGS! --
38
!! When you find a bug in this code, please write to me so that I can
39
!! fix the thing! Squash squash, you know? And I'm sure this code is
40
!! full of it. Too damned complex not to be. :)
42
!! -- Future Enhancements --
43
!! * The ability to use commands like `drop four dollars' and have the
44
!! computer what bills and coins to drop.
45
!! * It would be nice to have a change function, and a buy verb that
46
!! would allow things to actually be done with the money you

!! -- About the author --
51
!! Erik Hetzner (that's me) was born in San Francisco on 24 August
52
!! 1978. He has lived all over Northern California, and has been
53
!! playing Interactive Fiction since grade 4. He got re-involved with
54
!! IF about two years ago. His past header files are `timepieces.h'
55
!! and `printtime.h'. He is currently working on at least two pieces
56
!! of IF -- and entry for the 1997 IF contest, and a longer work for
57
!! release at sometime. He will soon release the interactive Inform
58
!! Game List, a neat bit of coding that simulates a library. He is
59
!! also fiddling with the possibilities of using literate programming
60
!! tools with Inform. He is currently an undergraduate at UC Berkeley,
61
!! and finds that he spends far too much time fiddling with Inform.
