Basic XML unpacker written in Python for usage with textures like FNF's

xml_unpacker.py

"""
Python script to extract images from XML/PNG pairs (I've used it for FNF)
Scans the "d" directory for any XML and PNG pairs, and if it finds them, creates a new folder in the "out" directory with the same name as the images
Note that it won't output images in the "d" directory if they have no corresponding XML file

Requires os, PIL, BeautifulSoup, lxml (html reader for BeautifulSoup) and re
"""
# Change this to the game's images folder (the one with the textures and XML files). 
d = r"C:\Funkin-master\assets\week7\images"

# Change this to the folder you want the final, separated textures to be outputted.
out = r"C:\funkin-assets-output"

how do i install this with colab?

For anyone that wants to do this with google colab, go here. https://github.com/frostzzone/xml-unpacker

still dunno how to do it

still dunno how to do it

you need to install python 3 (latest version) and additionally install BeautifulSoup4 (pip install beautifulsoup4) and Pillow ( pip install Pillow ) with command prompt

Also you have to change the output variable out = r"C:\funkin-assets-output" to out = r"YOUR DIRECTORY HERE (CAN'T BE RELATIVE FOLDER POSITION)"

how do i run this code?

OMG, THANK YOU SO MUCH! THIS IS WAY EASIER THAN WHAT I WAS DOING (Which Was Opening The Sprite Sheet Into A Image Editor And Then Taking A Screenshot Of EACH AND EVERY FRAME, And Then Importing Them Into Scratch, Cutting Out The BG, And Aligning Them.)
