Gallery for Custom Characters

[cuterobot]

I came up with this gallery code for a game with customizable characters. If you get a good ending, the character is added to the gallery. Feel free to modify/use it. I took the code to read tab-separated files from a few examples PyTom posted.

The game has six images to make up a character, an eye offset to match the eyes (and optional glasses) properly to the body, and a few text variables, for a total of eleven fields. The gallery displays each character in correct order for layering.

screens.rpy

In menu area:

Code: Select all

if renpy.loadable("gallery.txt"):
    textbutton _("Gallery") action ShowMenu("gallery")

On its own:

Code: Select all

init python:
    def parse_csv(filename):
        f = file(config.gamedir + "/" + filename)
        rv = [ ]

        for l in f:
             l = l[:-1]
             rv.append(l.split('\t'))

        f.close()
        return rv

gallery.rpy

Code: Select all

default gallery_current = 1

screen gallery:
    tag menu
    add "background.jpg"
    $ pictures = parse_csv("gallery.txt")
    $ gallery_last = len(pictures)
    $ gallery_first = 1

    $ aname = pictures[gallery_current - 1][0]
    $ alast = pictures[gallery_current - 1][1]
    $ job = pictures[gallery_current - 1][2]
    $ body = pictures[gallery_current - 1][3]
    $ eye_offset = int(pictures[gallery_current -1][4])
    $ normal = pictures[gallery_current -1][5]

script.rpy

just before the credits:

Code: Select all

if ending_bad == 0:
    $ output = str(aname) + "\t" + str(alast) + "\t" + str(job) + "\t" + str(body) + "\t" + str(eye_offset) + "\t" + str(normal) + "\t" + str(hair) + "\t" + str(bhair) + "\t"+ str(suit) + "\t" + str(glasses) + "\t" + str(ending) + "\n"
    python:
        with open(config.gamedir + '/' + 'gallery.txt', 'a') as gal:
            gal.write(output)

What happens when you get this error?

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/screens.rpy", line 1523, in execute
    screen gallery:
  File "game/screens.rpy", line 1523, in execute
    screen gallery:
  File "game/screens.rpy", line 1526, in execute
    $ pictures = parse_csv("gallery.txt")
  File "game/screens.rpy", line 1526, in <module>
    $ pictures = parse_csv("gallery.txt")
NameError: name 'parse_csv' is not defined

How do you fix it?
