Hello all,

I'm new to python programming, but am looking for a way to:
- iterate through dictionary keys, asking users to select a map location for the key
- map the new location.x, location.y values to the dictionary
- Select the next dictionary key and continue to map new x, y values until complete.

It's the last item I'm having a problem with. The script (below) either locks on the first key, or whips through all keys incredibly quickly. Can anyone help? Thanks!

city_list = {'city name' : [x, y]}

import math, random
import city_list
from scene import *

city_dict = city_list.city_dict

class MyScene (Scene):
    def draw (self):
        background(0, 0, 0)
        fill(1, 0, 0)
        image('_ACKS_ipad_map',0,50)
        for key in city_dict:
            text('Please select '+str(key)+' on the map',font_name='Helvetica',font_size=15,x=10,y=30,alignment=6)
            if len(self.touches) ==0:
                return
            if len(self.touches) ==1:
                location = self.touches.values()[0].location
                city_dict[key][0] = location.x
                city_dict[key][1] = location.y
                text(str(city_dict[key]),font_name='Helvetica',font_size=15,x=10,y=10,alignment=6)
                break


run(MyScene())

Hello all,

It took me a week, but is figured out what I was doing wrong. It was a mix of not understanding exactly how scenes render and how that loop effects other functions and some errors on how I was trying to handle local variables in loops. The finished script is up on Github. https://gist.github.com/8077804

Script to identify the coordinates for locations on an image map by having the user tap on the appropriate locations and saving the results into a dictionary that can be called by another script.

Requires an initial dictionary with at least the location name as a key and x, y coordinates as list values 0 and 1.

Cheers!

See the gist comments for some ideas...

Writing the file with "r+" instead of "w" did not make much sense to me.

Adding sublayers to the root_layer simplifies the update() and draw() code.

Reused the city_dict for data storage so new_list could be eliminated.

Added reading and writing to a .json file which is a more standard approach than using city_list.py as a data file.

(I could never really figure out how to create the city_list.py file in a way that would work with the main file.)

Hi there,

Thank you very much for the advice. I love Python, but it can be hard to figure out all the different options in Python and the best way of doing things.

I use the R+ option because I had to reuse the single file multiple times to get it right. :-) The dictionaries actually dictionary lists, with the list values being the X coordinates, Y coordinates, population, tribal affiliation and leader. Example:

city_dict = {'Corinium': [398.0, 456.5, 74, 'Bubroci', 'Eriadacus'], 'Aquae Solis': [343.5, 364.0, 249, 'Belgae', 'Ambiorix'], 'Durobrivae': [806.0, 365.0, 159, 'Caantii', 'Cingetorix'], 'Anderida': [830.5, 231.0, 249, 'Caantii', 'Segovax'], ...

I finished up the final map reader file as well, and posted it on GitHub. As always, any advice or suggestions would be fantastic. https://gist.github.com/Cgeist7/8129983

Thanks all!
