Hi all,
I’ve run into a bothersome problem with my source code. I took the money source from the Inform 7 website and tweaked it to fit my needs, but now that I’m starting to create objects, I have run into the problem that i cannot attribute my property “worth” to any of them. All that the debugger spits out is that "the property worth for [object] is not allowed to exist. Neither setting the worth to 0 or any other number works in allowing the game to compile. Here is my source code, sorry if it’s a little long. Some parts towards the top are incomplete but are not of any effect on the money system. Also disregard the portions in brackets as those are just reference materials or previous experiments that failed.
Money is a kind of thing. Money has a number called worth. The worth of money is usually 25.
The player carries a wallet. The wallet contains money. The printed name of the money is "[worth of the money] gold coins".
Understand "gold coins" as the money.
Definition: a thing is free if the worth of it is 0.
Definition: the money is free if the worth of it is 0.
Definition: a thing is for sale if it is not free.
Instead of taking something for sale, say "You'll have to pay for that."
Before buying something for sale when the money is not in the wallet, say "You're broke." instead.
Before buying something for sale when the money is free, say "You're broke." instead.
Before buying something for sale when the worth of the money is less than the worth of the noun, say "You don't have enough money for that."
Instead of buying an object:
decrease the worth of the money by the worth of the noun;
say "You fork over [the worth of noun] for [the noun], leaving yourself with [the worth of the money].";
now the worth is 0;
now the player is carrying the noun.
[An object has a number called value. Price is a kind of value. 10 gold specifies a price. An object has a price. The price of an object is usually 0 gold. After examining something for sale, say "It can be yours for [the price of the noun]"
Definition: an object is free if the price is 0 gold.
Definition: a thing is for sale if it is not free.
Instead of taking something for sale, say "You'll have to pay for that."
Before buying something for sale when the money is not in the wallet, say "You're broke." instead.
Before buying something for sale when the money is free, say "You're broke." instead.
Before buying something for sale when the price of the money is less than the price of the noun, say "You don't have enough money for that."
Instead of buying something:
decrease the price of the money by the price of the noun;
say "You fork over [the price of the noun] for [the noun], leaving yourself with [the price of the money].";
if the money is free, remove the money from play;
now the price of the noun is 0 gold;
now the player is carrying the noun.
The player carries a wallet. The wallet contains money. The printed name of the money is "[price of the money] in gold". Understand "gold" as the money.
Instead of taking the money:
say "Best to leave it alone until you need to buy something."

say "[The noun] is yours already."

You stop and look over your shoulder, fully expecting to see a guard about to tackle you, but instead notice a scrubby stall-keeper--presumably a conjurer, judging by the stacks of scrolls and other magical-looking wares heaped on her cart--frantically packing up.
'Oy! Stop right thar! Show me your peddling license!', bellows the city guard once more, but by then the stall-keeper had already began to run. You notice that in her rush, she dropped a small scroll.
