p5.js | translate() function

The translate() function in p5.js is used to specify the amount to displace objects within the display window. The x parameter is used to specify the left/right translation and y parameter is used to specify up/down translation.

Syntax:

translate(x, y, [z])

or

translate(vector)

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

• x: This parameter stores the value of left/right translation.
• y: This parameter stores the value of up/down translation.
• z: This parameter stores the value of forward/backward translation.

In another syntax, we can only provide the p5 vector object.

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

Example 1: This example uses translate() function to specify the amount to displace objects.

function setup() {

    // Create Canvas of given size
    createCanvas(580, 450);
}

function draw() {

    // Set the background color
    background(220);

    // Fill the color
    fill('lightgreen');

    // Set the border weight
    strokeWeight(5);

    // Create rectangle
    rect(10, 10, 400, 300);

    // Translate the rectangle
    translate(30, 30);

    // Create rectangle
    rect(10, 10, 400, 300);

    // Translate the rectangle
    translate(30, 30);

    // Create rectangle
    rect(10, 10, 400, 300);
}

Output:

Example 2: This example uses translate() function to specify the amount to displace objects within the display window.

function setup() {

    // Create Canvas of given size
    createCanvas(580, 450);
}

function draw() {

    // Set the background color
    background(220);

    for(var i=0, j=255; i<255, j>0; i++, j--) {
        fill(i, j, i);
    }

    // Set the stroke weight
    strokeWeight(5);

    // Use translate function
    translate(width / 2, height / 2);

    translate(p5.Vector.fromAngle(millis() / 1000, 200));

    // Create rectangle
    rect(10, 10, 40, 30);
}
