To loop a canvas animation in HTML5, you can use the requestAnimationFrame() function along with a recursive function. Here is an example code snippet that demonstrates how to create a looping animation on a canvas element:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
<!DOCTYPE html>
<html>
<head>
<title>Canvas Animation Loop</title>
</head>
<body>
<canvas id="myCanvas" width="400" height="400"></canvas>
<script>
var canvas = document.getElementById('myCanvas');
var ctx = canvas.getContext('2d');
function draw() {
// Clear the canvas
ctx.clearRect(0, 0, canvas.width, canvas.height);
// Draw your animation here
ctx.fillStyle = 'blue';
ctx.fillRect(50, 50, 50, 50);
// Request next frame
requestAnimationFrame(draw);
}
// Call the draw function to start the animation
draw();
</script>
</body>
</html>

In this code snippet, the draw() function is called recursively using requestAnimationFrame(), which creates a loop that continuously updates the canvas animation. You can customize the animation by adding more drawing operations inside the draw() function.
