Title: Python script map loader! (can be used to convert maps to e.g. JSON files)
Post by: jammyjamjamman on 11 December 2017, 11:41:09

==COPIED FROM MEGAGLEST BOARD==
I wanted to read megaglest maps so I could use them in other things. So, I wrote this *dirty* python 3 script to read a map into a python dictionary. The dictionary is formatted such that it can be easily written to disk as e.g. a JSON file.
Here's a link if anyone else is interested in reading maps in python: https://drive.google.com/file/d/190gXUyiuNKR3ITFtN_zF5MFc6Qogca_f/view?usp=sharing (https://drive.google.com/file/d/190gXUyiuNKR3ITFtN_zF5MFc6Qogca_f/view?usp=sharing)

• Maps  included were made by atze.
• The script no longer requires numpy! It should be completely compatible with cpython3.
• There is example code, commented out, under if __name__ == "__main__":, which demonstrates previewing atze's 6player.mgm map data in matplotlib and saving the map as a JSON object file.
• The original map data is is stored as a flat, 1d array of numbers, but the script converts the flat array into a 2d array in the shape of the map.

The code is very badly written and has the following problems (in descending order of importance):

• Does not support  "version 1" maps (glest maps?).
• Needs numpy to read map data (unnecessary as performance not an issue + requires extra dependencies).
• Code is generally a mess which leads to memory inefficiencies in various places.

I may fix these problems sometime, or feel free to fix them yourself if you want :).

Sounds like a handy utility. Maybe put it on a public source code repository (GitHub, Gitlab, Bitbucket etc.) so it's easier to inspect the code and provide patches?

I've placed a backup copy of today's state at https://downloads.megaglest.org/tools/read_map_a2.zip

Thanks for backing it up! Yeah I shouldn't really be using g-drive for storing the script especially since I think there's some clause that "they own the data there"  :O  :look: (don't quote me on that). I'll try to move it over to a git repo asap.

P.s. I've added the license for the script to my post, And I will add it to the top of my script later.
