bad-apple

Bad Apple printed out on the console with Python!

Preface

A word of disclaimer, while the final code is somewhat original, this project is an amalgamation of different code snippets that I found online. As the main YouTube Video begins to gain traction, I feel the need to inform the audience that this code is NOT ENTIRELY ORIGINAL.

The concept of playing Bad Apple!! on a Command Line Interface (CLI) is not a novel idea and I am definitely not the first.

There are many iterations and versions around YouTube and I wanted to give it a shot. The intent of posting the video on YouTube was to show a few friends of a simple weekend project that I whipped up in Python.

My own video can be found here.

Running this code

Thanks to TheHusyin for adding a requirements.txt file for easier installs.

First, ensure that you set your terminal to the directory of this repository.

cd bad-apple

Install the necessary dependencies and packages by using:

pip install -r requirements.txt

And to run the code:

python touhou_bad_apple_v2.py

And just follow the on-screen prompts.

Performance optimizations

Currently, my implementation of a rudimentary static time.sleep() function results in an incremental error over time. This thus leads to the frame accucracy drifting.

I am also looking into improving frame extraction and generation times.

Current known issues and bugs

Despite being a somewhat simple program, my crappy implementation has led to a lot of unresovled bugs and issues. I am currently looking at fixing some of them.

1. block=False is not supported in Linux

I am currently trying to find alternatives to the playsound library. Using two different threads is not an option currently as I was running into desynchronization issues.

This issue has been fixed in v3, alongside other performance improvements.

2. No such file or directory: 'ExtractedFrames/BadApple_1.jpg'

Not really sure how this is happening, but will be looking into fixing it. I was unable to replicate the error but I assume it is due to my botchy implementation of file directories for the assets.

Version descriptor

1. touhou_bad_apple_v1.py

First rudimentary version that accomplishes basic frame extraction and animation. Utilizes threads, but suffers from heavy synchronization issues.

2. touhou_bad_apple_v2.py

Extended version that includes a "GUI", some basic file I/O. Suffers from slight synchronization issues. Core program logic was completed in 24 hours with some minor tweaks and comments afterwards.

3. touhou_bad_apple_v3.py

Current development version. Improved frame time delay and better file I/O. Looking to implement threading to expedite frame extraction and ASCII conversion.

Functions

The main functions will be listed here.

play_video()

Reads the files from the previously generated ASCII .txt files and prints it out onto the console.

play_audio()

Plays the bad apple audio track.

progress_bar(current, total, barLength=25)

A simple progress bar function that generates the status of both frame extraction and ASCII frame generation. This code was taken from a StackOverflow thread.

current is the current value/progress of the process.

total is the desired/intended end value of the process.

barLength=25 sets the length of the progress bar. (Default is 25 characters)

ASCII Frame generation

Not a particular function, but a group of functions.

resize_image()

greyscale()

pixels_to_ascii()

These functions are called in the ascii_generator() function to convert image files to ASCII format and stores them into .txt files.

Note that the ASCII conversion code is not original, and was taken from here.
