Hi all! I'm trying to write a basic text adventure game to start
learning python (just for fun). I've gone through the first four
chapters of a "learn python game programming book" and I'm having
trouble with the exercise on writing a text adventure. I've been
piecing together what is in the book with some examples I found
online. My goal with this question is not to necessarily make the code
I've written work, but to gain a fundamental understanding of the
concepts.
Can someone show me how to organize a text-based game with
these things kept in mind: 1)Each room will be a function
2)Direction(N,S,E,W) 3)"Look at" 4)Pick Up 5)Quit 6)Accumulated Gold
Coins 7) Find all the Gold 8)Win/Lose
aug dawg recommended classes, with which I agree, but that may be
premature for you.
1) define the functions once, outside the while loop.
2) there is no need for global gold. global only makes sense inside a def.
3) do not reset gold to 0 at the start of each loop cycle. Do that
before the loop.
4) write a help function to handle the help text rather than repeating
the text multiple times.
5) use initial lower case for function and variable names. This is a
convention that makes
it easier to read each other's code as well as your own code.
6) check the spelling of wooley mamoth
7) while keepGoing == True: can be simplified to while keepGoing:
8) write a function to get a command. Have it do the uppercasing and
checking for / processing of common commands such as HELP,
9) have the functions return text rather than printing it. Use triple
quoted text. e.g.:
def Room1():
description = """You find yourself in a large room. Above you is a
massive crystal
chandelier. In front of you is round stone fountain, spewing water."""
Then in the loop:
print Room1().
This separates data from logic and paves the way to convert things to
classes & dictionaries.
I'm looking for the simplest version of this as possible,
because I'm having trouble with the concepts. I'm only showing my code
to give you an idea where I'm at. However, I would really like someone
to lay out a little code structure for me.
I'm using Python 2.6.5 on a Mac Version 10.4.11 and don't consider
myself computer literate, so bear with my ignorance please.
Also, don't feel like you have to correct my code...please
just create your own example of code structure to get me on the right
track.
Here is the start of my game:
"""FirstGame.py
First try at creating a text-based adventure game. Trying to learn
the basics
of creating functions and using if and loops.
