Step-by-Step Guide to Creating a Timer in Processing

Processing is an open-source programming language and development environment for creating images, animations, and interactions and running on the Java platform. It is highly regarded for its user-friendly design, object-oriented structure, and platform independent nature.

In this guide, we’ll show you how to create a timer in Processing – step-by-step.

What You Need to Create a Timer

To create a timer in Processing, you’ll need the following components:

• Processing Personal Development Environment : An open source development environment used to write and compile code
• Time Library: A library of time related functions
• The Timer Class: A library of various time-keeping commands

Step-By-Step Guide

You’ll follow the steps outlined below to create a timer in Processing.

1. Download and install the Processing Personal Development Environment.
2. Create an instance of the timer class.
3. Use the time() method to query the current system time.
4. Use the setDelay() function to specify a specified time interval.
5. Add code for the timer to detect when the interval has been passed.
6. Use the timeElapsed() function to retrieve the elapsed time since the timer started.
7. Add code to render the timer on the canvas.
