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.
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.
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);
