Atari Sparklines

First ten seconds of MsPacman

Inspired by this tweet.

Code to get a sparklines plot from the RAM values of an Atari game.

Usage

Run python atari_sparklines.py to, by default, get the sparklines plot of the RAM values for the first ten seconds of MsPacman and save them to sparklines.png.

The values of RAM for every frame are plotted. There are 60 frames-per-second. At each frame, a random action is taken, i.e. a random button on the Atari controller is pressed.

Arguments

python atari_sparklines.py --game SpaceInvaders, gets the RAM values for Space Invaders

python atari_sparklines.py --n_frames 600, gets the first 600 frames (10 seconds)

python atari_sparklines.py --n_rows 16 --n_cols 8, layout of the sparklines plot in the figure (this must equal the number of RAM values, which should always be 128)

python atari_sparklines.py --fig_width 24 --fig_height 16, width and height of the figure

python atari_sparklines.py --color black --line_width 0.7, color and thickness of the sparklines

python atari_sparklines.py --fig_name sparklines, name of the saved figure (which has the .png extension appended)

Requirements

python 3.6+
