Random Walker

A random walker is a simple idea: start at some point, and then every frame, move in a random direction. As time goes on, you’ll randomly walk all around the screen. You can think of this like randomly scribbling on a piece of paper. This might sound simple (and it is), but it’s also useful in all kinds of applications and explores the idea of emergence: the process of complicated (and sometimes beautiful) patterns emerging from simple rules. In this tutorial we will creating an arraylist and defining a class and variables.
