p5.js | frameRate() Function

The frameRate() function in p5.js is used to specify the number of frames to be displayed every second. Calling frameRate() with no arguments returns the current framerate. The draw function must run at least once before it will return a value. This function is same as getFrameRate() function.

Syntax

frameRate( c )

Parameters: The function accepts single parameter c which stores the value of frame rate variable.

Below program illustrates the frameRate() function in p5.js:

Example:

function setup() {

    // Create canvas of given size
    createCanvas(500, 200);

    // Set the font size
    textSize(20);

    // Use frameRate() function
    frameRate(3);
}

function draw() {

    // Set the background color
    background(0, 153, 0);

    // Display the output
    text("Frame Count with frameRate " +
         int(getFrameRate()), 100, 100);
}
