well the 'planet' object, in terms of the game, contains variables, methods
to manipulate that object.

a.x is the x coord
a.y is the y coord

another object in the code will be 'fleet' object. ideally this will
contain information like the number of ships travelling from one planet to
the next. it will also contain origin and destination coord's (as above),
so:

org_x=a.x
org_y=a.y
dest_x=z.x
dest_y=z.y

the only variables that are hardwired are the coordinates, ship production,
name). they're first assigned values when the planet object is initialized
(so i have 26 objects to initilize, those init methods are called only
once)

> But do you ever do things like iterate over them, or access them by name?

i will have to iterate over them. each planet has a ship production value. so
the number of ships is going increase every year. for every planet i'll
need:

a.ships =a.ships + a.production

and i need that 26 times. you can see why i'm looking for a solution.

i'll also have up to 25 fleets at a time, and a variable such as:

fleet1.distance, will be decremented each turn...


i started off using C on the palmpilot, ported it to tcl/tk for a windows
version, and recently started a python port...

so far with each port, i've made the code a little cleaner trying to take
advantage of what each language has to offer.

at the url below (the 'GEB' link when you get there)

it has (older) screen shots but the latest version of the pilot and windows 
version are there. it's actually a re-write of an old c64 game.
