Need some simple coding help

[mx2k]

Hello @ all,

we have written a small program (code below) for our own
in-developement rpg system, which is getting values for 4
RPG-Characters and doing some calculations with it.

now we're trying hard to find out how to get it working with 'n'
Characters, so you will be asked to enter a number at the beginning,
asking you how many characters you want.

anyone out there who could help us?

also i wonder how i can read the current date/time (we don't understand
datetime() )and put it into a variable and print that variable?

doing python since yesterday :)



Code follows:
# Timeline Tools for an RPG system - Written in Python 2.4
# Created by [mx] networkz @ 27.02.05 - mx@mx2k.net
# Collaboration work of mx2k & Tschabo (von Konsti)

# import math

#-------------------------------------------------------------
#defining functions

#header text

print ''
print ' Timeline System - Alpha Version 0.8.15 '
print '______________ _______________ _______________ '

print '* created 2005 *'
#print '============== =============== =============== '
print ''

Why don't you try describing what it is you're trying to do in some more
detail -- your code is fairly unreadable.

I gather you want to do something like:

py> class Character(objec t):
.... def __init__(self, name, initiative, reaction_time):
.... self.name = name
.... self.initiative = initiative
.... self.reaction_t ime = reaction_time
.... def __repr__(self):
.... return 'Character(%r, %r, %r)' % (
.... self.name, self.initiative , self.reaction_t ime)
....
py> def get_char():
.... return Character(raw_i nput("Char 1 Name: "),
.... int(raw_input(" Char 1 Initiative: ")),
.... int(raw_input(" Char 1 Reaction Time: ")))
....
py> n_chars = int(raw_input(' Number of Characters: '))
[...I type '2'...]
py> characters = [get_char() for _ in xrange(n_chars)]
[...I type 'Steve', '3', '2', etc....]
py> characters
[Character('Stev e', 3, 2), Character('mx2k ', 5, 1)]

But it's not clear to me what it is you want done with the characters.
It looks like you're maybe trying to go through rounds of combat,
sorting characters by initiative...? What exactly is the process you're
attempting to follow?

If you try to describe the problem in words, you'll probably get more
help. (Code is generally good too, but if it's not clear what you're
trying to do with the code, no one will be able to make use of it.)

Re: Need some simple coding help

indeed, we're it is our combat timeline. we enter the initiative and
reaction time, it should find out the lowest then the next, then the
'n'th etc. and shouw it on the screen like
Next action 'Character Name1' at tick No 'Initiative1
2nd action 'Character Name2' at tick No 'Initiative2'
[...]
'n'th action 'Character Name n' at tick No 'Initiative n'

Now you enter a value by which the initiative should be increased,
then adding reaction time to that value and then adding the result to
reaction time. Now soring again by lowest,next,'n' th, etc. and then
again showing the output, asking for another number etc.

Re: Need some simple coding help

ah, and sorry for that 'unreadable' code, but that was our first try of
coding ever. we're working through the python documentaion right now -
and - thanks to the post by STeVe we at last now that we have to
construct a class for our purpose.

Thx for any help

Not sure if I got your calculation right, but something like this should
work:

py> characters
[Character('Stev e', 3, 2), Character('mx2k ', 5, 1)]
py> def get_init(charac ter):
.... return (character.init iative + character.react ion_time +
.... int(raw_input(' %s initiative: ' % character.name) ))
....
py> def print_initiativ es(characters, rounds):
.... for _ in range(rounds):
.... inits = dict([(character, get_init(charac ter))
.... for character in characters])
.... for character in sorted(inits, key=inits.__get item__):
.... print character, inits[character]
....
py> print_initiativ es(characters, 3)
[... I type '5', '6' ...]
Character('Stev e', 3, 2) 10
Character('mx2k ', 5, 1) 12
[... I type '9', '1' ...]
Character('mx2k ', 5, 1) 7
Character('Stev e', 3, 2) 14
[... I type '1', '2' ...]
Character('Stev e', 3, 2) 6
Character('mx2k ', 5, 1) 8

If you want the characters in the opposite order, simply use
sorted(inits, key=inits.__get item__, reverse=True)
instead of
sorted(inits, key=inits.__get item__)

HTH,

Well, you don't *have* to -- it could be done all with lists as you had.
But I think you'll find that it lends itself to a much cleaner
solution. Also, if you ever find yourself writing a list of 5 or more
if statements, you're probably not going at the problem from the easiest
angle. Ask around, tell people what you're trying to do, and what you
think your if statements are doing now, and they can probably point you
to the easier way.

If I correct understand your goal, you might use a priority queue (heap)
(there is one in the standard library). You insert all chars with the
initial response time as the 'key'. You remove the one who is going to
respond first and perform his actions. If he is to get another turn, add
his next reaction time to the current value and insert him back into the
queue. The next character to act will then be at the front of the queue.
Repeat.

Re: Need some simple coding help


thx again, this code is nearly doing as we want and we think to have
figured out how to change it to meet our requirments. also thx for the
tip using a heap...

should there be more problems i'll post again!
