Random Walk Start

//This is a starting point for a random walk challenge.

//

// You will need to fix it - the circle currently just walks in a dull straight line.

// It should move randomly but it should only ever take a SMALL step from where it was, each frame of animation.

​

// Variables to track position of "walker" (initialised in setup()).  You could use an object if you prefer.

​

let x;

let y;

​

// This "setup" function will be called only once.

function setup() {

  createCanvas(600, 600);  //(width and height in pixels)

  //initialise our position variables.  You can change these numbers.

  x = 300;

  y = 100;  

  background('gray');

  // Let's slow down the animation to 2 "FPS" so you can see what's happening

  frameRate(2)  // (You can speed this up to 60 when you want.) 

}

​

​

// This "draw" function will be found and called over and over to make an animation (up to 60 times per second!)

function draw() {

  //Step 1. draw the "walker"

  const colour = random( ["blue", "yellow"] )

  fill(colour)

  //fill('yellow');

  circle(x, y, 30);

  //Step 2. move the walker a little bit.  This is no good - it always goes in the same direction!  

  // Not very random!  Can you fix it?  what about vertical movement?

  x+= 5;

  y += random(-5, 5);
