I have extracted just the relevant code.
Its possible you extracted too much but....
class Player(object):
"""The player in the game."""
def __init__(self, name, currentRoom=None):
def take(self, item):
"""Take (pick up) an item from the current room."""
if item == self.currentRoom.item:
self.items.append(item)
print self.currentRoom.item + " added to player's inventory..\n"
# remove item from currentRoom
self.currentRoom.item = ''
Here at least you are making item a string rather than an Item()
def examine(self, item):
"""Prints description of item."""
if item in self.items:
# Error: 'str' object has no attribute 'description'
print "Item Description: " + item.description + ".\n"
And here you access the item.description which doesn';t exist for strings.
But you could get rounfd that by converting item to a str(). Then if it
is an Item instance your __str__ method gets called - thats why you
defined it right? - and if its already a string the same string gets
returned...
print "You are not holding the " + item + " to examine!\n"
class Item(object):
"""A useful item in the game."""
def __init__(self, name, description, location):
self.name = name
self.description = description
self.location = location
def __str__(self):
"""Description of item."""
return self.description
class Game(object):
def play(self, character):
def main():
# Room descriptions
room5 = Room(name="hallway", description="You are in a dark hallway.",
item="diary")
Notice that the item is just a strinng, not the diary object. Which
doesn't actually exist yet anyhow!
# Item descriptions
diary = Item(name="diary", description="grey-covered Croxley diary",
location=room5)
This appears to be the only place you ever instantiate an Item? But this
is not what you assigned to room5...
So you are not assigning Items to the rooms. Unless its in the code you
deleted?
