Interactive Processing.js Sketch

This post demonstrates how to include interactive Processing.js sketches in your MDBlog posts.

The Magic of Processing.js

Processing.js brings the Processing visualization language to the web. You can create interactive animations, generative art, and data visualizations right in your blog posts.

How It Works

To include a Processing.js sketch in your post:

1. Add the JavaScript file to the front matter using the js property
2. Upload your Processing.js library to assets/js/
3. Include your sketch code in a code block or separate file

Sample Sketch Code

Here's the Processing code for a simple interactive sketch:

// This would be processed by Processing.js
void setup() {
    size(400, 300);
    background(50);
}

void draw() {
    // Draw colorful circles that follow the mouse
    fill(random(255), random(255), random(255), 100);
    noStroke();
    ellipse(mouseX + random(-20, 20), mouseY + random(-20, 20), 30, 30);
    
    // Fade the background slightly
    fill(50, 10);
    rect(0, 0, width, height);
}

Multiple JavaScript Files

You can also include multiple JavaScript files by using an array in the front matter:

js: 
  - processing.min.js
  - sketch.js
  - custom-functions.js

Use Cases

Processing.js sketches are perfect for:

• Data visualization - Interactive charts and graphs
• Generative art - Algorithmic and procedural art
• Educational content - Interactive demonstrations
• Games - Simple browser-based games
• Simulations - Physics simulations, particle systems

Getting Started

1. Download Processing.js from processingjs.org
2. Upload it to your assets/js/ folder
3. Create your sketch and add the js front matter
4. Publish your post!

Note: Make sure to include the Processing.js library file in your assets folder for the interactive features to work.
