Hi, I'm a total newbie too, and I'm kind of replying to see if my
instinct on the whole GOTO thing is correct. It's hard to learn a
language without any feedback!
I used GW and Color Basic when I was a kid so I know all about GOTO (and
it was a mess! I programmed one of those interactive stories in grade 12
using it, it took all semester and was anything but elegant!)
I would expect with Python, instead of using GOTO you use defined
functions.
So for instance, you could define chapters as functions
def chapter2():
print "You've chosen to leap over the chasm"
print "too bad you forgot you were carrying an anvil"
print "What part of b-bye don't you understand?"
Even better is to define a Chapter class, with the various properties
and methods pertinent thereto, then make each chapter an instance of
that class.
class Chapter:
def __init__(self, desc, ques=None, **actions):
self.desc = desc
self.ques = ques
self.actions = actions
self.prompt = ", ".join(actions.keys())
def describe(self):
print self.desc
def ask(self):
if self.ques:
print self.ques
for i in range(10):
ans = raw_input(self.prompt).lower()
next = self.actions.get(ans, None)
if next:
return next
else:
print "Invalid response"
else:
print "Too many failed attempts"
# CORRECTION - indent
def main():
chapters = [None]*11 # allow for 10 chapters starting with 1
chapters[1] = Chapter("Ahead of you, you see a chasm.", "Attempt to
jump over it?", y=2, n=3)
chapters[2] = Chapter("Oops - that anvil is heavy. You die.")
chapters[3] = Chapter("Good choice.", "Pick a direction", n=4, s=5)
chapters[4] = Chapter("It's cold in here.", "Pick a direction", e=1,
w=2)
chapters[5] = Chapter("It's hot in here.", "Pick a direction", u=6, d=3)
chapters[6] = Chapter("Congratulations - you found the gold.")
next = 1
while True:
chapter = chapters[next]
chapter.describe()
next = chapter.ask()
if not next:
print "Game over"
break
main()
