This is a little snippet I’ve wanted to try for quite some time. I finally got around to recreating this iconic feature from Google Maps: the ability to drag and drop this little guy, known as Pegman, to switch to Street View.
TL;DR
Click and drag the little icon in the bottom-right corner over the map:
The structure is straightforward. I have:
<div> <h2> CSS </h2> <p>Positioning everything is simple, as you can see in the source code above, but the most important part is the rotate property. This is dynamically updated using JavaScript:<br> </p> <pre class="brush:php;toolbar:false">#pegman { /* other styles */ rotate: var(--r); }
The rotate value changes based on user interaction, which we’ll dive into next.
Everything here revolves around user interaction. JavaScript handles:
const pegman = document.querySelector('#pegman'); let isDragging = false; let initialX = 0; let initialY = 0; let inactivityTimeout; let lastX = 0; const timeout = 25; const maxDegrees = 50; // Event listeners pegman.addEventListener('mousedown', onMouseDown); document.addEventListener('mousemove', onMouseMove); document.addEventListener('mouseup', onMouseUp);
Let’s break down each function:
This starts the drag by recording the initial mouse position and toggling the isDragging flag.
const onMouseDown = (e) => { isDragging = true; initialX = e.clientX; initialY = e.clientY; };
This handles Pegman’s movement and rotation during the drag. It ensures:
const onMouseMove = (e) => { if (!isDragging) return; const dy = e.clientY - initialY; const dx = e.clientX - initialX; // Limit rotation range let rx = Math.max(-maxDegrees, Math.min(maxDegrees, dx - lastX)); pegman.setAttribute('style', `--r: ${rx}deg`); // Animate Pegman's position pegman.animate({ translate: `${dx}px ${dy}px` }, { duration: 100, fill: 'forwards', }); // Reset rotation after inactivity clearTimeout(inactivityTimeout); inactivityTimeout = setTimeout(() => { lastX = dx; pegman.setAttribute('style', `--r: 0deg`); }, timeout); };
This resets Pegman’s state once the user stops dragging:
const onMouseUp = () => { isDragging = false; // Reset rotation pegman.setAttribute('style', `--r: 0`); // Animate Pegman back to its original position pegman.animate({ translate: `0px 0px` }, { duration: 500, fill: 'forwards', easing: 'ease', }); // Clear residual state inactivityTimeout = setTimeout(() => { lastX = 0; }, timeout); };
This snippet highlights how simple animations and interactivity can recreate an iconic user experience. Key takeaways:
Feel free to fork the CodePen, make changes and let me know what you think! ??️
I'm using the original sprites from google, which you can see here and make experiments:
Did you know? ✨ The Google Maps location I used is the real Santa Claus Village!
Fun fact: Santa’s Finnish name is Joulupukki, and he originally from Finland ???
