I am having a very bad time with this exercise. So far, all I can manage is more or less an imitation of Exercise 43. Mine is a generic castle adventure, complete with items, trap doors, hidden passageways (to be triggered by a cheesy hidden book in the library, naturally), etc.
What I’d like to do is, use an Engine() class to keep track of/update some things that I can then display at every user interaction. For example, current room, inventory, and (eventually) player health. Engine() runs over and over until the user either wins, or dies. A lot like Ex. 43.
The problem is: I have no idea how to pass values in and out of functions/classes and/or call them properly, apparently.
So far here’s my code:
# Welcome to Generic Castle Adventure!
# details to be implemented later
from trapdoor import TrapDoor
# we will use the below for error-handling
from sys import exit
# and generating random numbers, for combat/puzzles etc.
from random import randint

sleep(1)
print "You're not sure what else happened, but you're"
print "alone now. It smells like urine AND vomit in here, yuck.\n"
sleep(1)
print "You are in a broom closet just off the"
print "Great Hall of a generic European style castle.\n"
sleep(2)
print "There are 2 things here: %s and %s\n" % ('dusty shelf', 'old broom')

the_game.play()It doesn’t work, of course. For instance, here’s what happens if I try to take the broom while still in the broom closet:
> take broom
You take the also-dusty, well-worn broom.
You are in the <__main__.GreatHall object at 0x000000000295EF88>
You have these items: Empty
Description of Great Hall:
The main space is filled with several
long feasting tables, littered with debris from last night's
festivities.
You find it odd that no one has cleaned up the mess. In fact,
you hear no signs of normal life - the castle seems empty so far.
You see 2 possible ways to go:
There is a stairway leading to the private quarters.
There is a grand archway leading to the throne room.
Which way will you go?
[stairway, throne room, stay here]
> See, inventory is still “empty.” And I don’t understand why that weird code prints (<main.GreatHall etc>) rather than simply saying “You are in the Great Hall.”
I have no idea how I would update the inventory, or exactly where the value of “inventory” is being stored so I could change it.
Help!
