Coding Art

Lesson 3 - Following Circles

Before we start let’s introduce 4 things needed to make our Art

JavaScript- Coding language that makes things interactive

Function- Set of Steps that tells the computer how to do or make something

Variables- giving a name to a value so that we can easily call upon that name and get that value quicker

If,Then Statement- IF this happens THEN i want this to happen, ELSE i want something else to happen

First we have to get some things ready with the setup function!

function setup() {
    createCanvas(400, 400);
    colorMode(HSB);
    noStroke();
}

Explanation of the setup!:

function setup() { //  what gets run first when you hit the play button, sets background color, color mode etc.
    createCanvas(400, 400); // creates our picture frame like a canvas that you paint on
    colorMode(HSB); // HUE, SATURATION AND BRIGHTNESS - the color, intensity of that color, how light or dark that color is
    noStroke(); // no borders on circles
}

Next we can actually start drawing with the draw function

 function draw() {
    fill(random(0,360), 70, 90) ;
    ellipse(mouseX, mouseY, 80, 80);
}

Explanation of the draw function!!:

function draw() {
    fill(random(0,360), 70, 90); // our circles will be a random color of the rainbow
    ellipse(mouseX, mouseY, 80, 80); // will follow our mouse on our canvas and the circles will be 80 pixels
}

Final Code for this Lesson!

function setup() {
    createCanvas(400, 400);
    colorMode(HSB);
    noStroke();
}
  function draw() {
    fill(random(0,360), 70, 90) ;
    ellipse(mouseX, mouseY, 80, 80);
}
