p5.js Coding Examples
Find some free examples in your Tynker Student Dashboard. Login at tynker.com, then go to Projects > Create Project > p5.js. Inside you’ll see categories you can select from. If you’re an absolute beginner, start with Basic Drawing. Or try some of the short examples below!
Basic Drawing. Put on your cartoonist’s hat and make some original comics and shapes. Learn how to draw shapes, lines, then learn about irregular shapes and design your own Origami Animal.
Art Style. Take inspiration from famous artists, then recreate their own work in the same style—using code!
Math Art. Make intricate patterns and colors! You’ll have a blast learning how to make animations and interactive art projects.
Basic Animation
This animation moves an ellipse across the canvas.
function setup() {
createCanvas(400, 400);
}
function draw() {
background(220);
// Move a shape across the canvas
ellipse(frameCount % width, height / 2, 50, 50);
}
Interactive Drawing
The ellipse seems to follow your mouse!
function setup() {
createCanvas(400, 400);
}
function draw() {
background(220);
// Draw a shape at the mouse position
ellipse(mouseX, mouseY, 50, 50);
}
How does p5.js work?
p5.js is a creative coding framework that simplifies the process of developing interactive and visual web applications. It operates through a straightforward structure consisting of two primary functions, setup() and draw(), making it accessible even to those with limited programming experience. Here’s a breakdown of how p5.js works:
Setup and Draw Functions:
- The setup() function initializes program settings and variables, typically used for defining canvas size and configuration.
- The draw() function is called continuously, allowing for the creation of animations and updates to visual content.
Canvas Handling:
- p5.js automatically generates an HTML5 canvas element, where all graphic elements are drawn.
- You can customize the canvas size, position, and background color using functions like createCanvas() and background().
Drawing and Interaction:
- p5.js provides a range of functions for drawing shapes, lines, and text, simplifying the creation of visuals.
- User interactions are easily managed through built-in event handling functions like mousePressed() and keyPressed(), enhancing interactivity.
Additionally, p5.js includes features like image manipulation, sound integration, and integration with external libraries, expanding its creative potential. After developing a project, creators can export it as a web page or share it online, enabling them to showcase their interactive and visual creations with a global audience. Overall, p5.js empowers artists, designers, educators, and beginners to engage in creative coding, offering a user-friendly approach to web development for a wide range of applications.
Can you make Games with p5.js?
Yes, you can create games with p5.js. p5.js is a JavaScript library that is particularly well-suited for creative coding, including game development. It provides a simple and intuitive way to work with graphics, animations, and interactivity, making it popular among artists, designers, and programmers who want to create interactive visual experiences, including games.
What are Processing and p5.js?
Processing and p5.js share a common goal of making creative coding accessible to a wide audience, but they differ in their implementation. Processing is stand-alone software with its own integrated development environment (IDE), while p5.js is a JavaScript library that can be used within any web browser.
p5.js inherits many of Processing’s features while leveraging the web’s capabilities, making it more accessible and versatile for online projects.
How to Make Your First Generative Art with p5.js?
