Coding Art

Lesson 8 - Random Lines

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(340, 340);
    colorMode(HSB);
}

Explanation of the setup!:

function setup() { // what gets run first when you hit the play button, sets background color, color mode etc.
    createCanvas(340, 340); // 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
}

Next we can actually start drawing with the draw function

 function draw() {
    stroke(random(360), 100, 100);
     line(random(width), random(height), random(width), random(height));
}

Explanation of the draw function!!:

function draw() { // tells the computer we are making the art now
    stroke(random(360), 100, 100); // makes each line a random color of the rainbow
     line(random(width), random(height), random(width), random(height)); // makes each line appear at a random point on the screen
}

Final Code for this Lesson!

function setup() {
    createCanvas(340, 340);
    colorMode(HSB);
}
function draw() {
    stroke(random(360), 100, 100);
     line(random(width), random(height), random(width), random(height));
}

Your Finished Product Should Look Something Like This!
