p5.js | createVector() function

• Last Updated : 05 Oct, 2021

The createVector() function in p5.js is used to create the new p5 vector which contains both magnitude and direction. This provides a two or three-dimensional vector, specifically a geometric vector.

Syntax:

createVector([x], [y], [z])

Parameters: This function accepts three parameters as mentioned above and described below:

• x: This parameter stores the x component of the vector.
• y: This parameter stores the y component of the vector.
• z: This parameter stores the z component of the vector.

Below programs illustrate the createVector() function in p5.js:

Example 1: This example uses createVector() function to draw a line.

Javascript

 function setup() {     // Create a Canvas    createCanvas(500, 550);} function draw() {        // Vector initialisation    // using createVector    t1 = createVector(10, 40);    t2 = createVector(411, 500);        // Set background color     background(200);        // Set stroke weight    strokeWeight(2);        // line using vector    line(t1.x, t1.y, t2.x, t2.y);        translate(12, 54);      line(t1.x, t1.y, t2.x, t2.y);}

Output: Example 2: This example uses createVector() function to draw a circle.

Javascript

 function setup() {     // Create a Canvas    createCanvas(500, 550);}  function draw() {        // Vector initialisation    // using createVector    t1 = createVector(10, 40);    t2 = createVector(41, 50);        // Set background color     background(200);        // Set stroke weight    strokeWeight(2);        // Fill yellow    fill('yellow');        // ellipse using vector    ellipse(t1.x*millis() / 1000 * 20,            t1.y, t2.x+100, t2.y+100);}
