This is a version of Pong that synchronizes the bounces with a song. You are free to use this code for any purpose, I only ask that you link back to this repo.

Basic Usage

1. Install the required dependencies:

   pip install pygame numpy cvxpy mido
   

   Alternatively, you can use uv to install the dependencies:

   pip install uv
   

2. Run the game with a MIDI file:

   curl -o example_midi.mid https://bitmidi.com/uploads/72257.mid # download a MIDI file
   python pong.py example_midi.mid
   

   Or using uv run:

   uv run pong.py example_midi.mid
   

3. For non-MIDI audio files, you need to provide a JSON file with note timings:

   python pong.py path/to/your/audio_file.mp3 --times_file path/to/your/times.json
   

   Or using uv run:

   uv run pong.py path/to/your/audio_file.mp3 --times_file path/to/your/times.json
   

   The JSON file should contain a list of times (in seconds) when the ball should hit a paddle.
