Questiondrawing A Random Bezier Curve 10 times then reset Pin
LarsAlaska28-Feb-20 11:21
MemberLarsAlaska28-Feb-20 11:21 
Here is the code below I am hoping for help on. What I believe ought to happen is ten randomly colored/ shaped lines are successively drawn 1 every 500ms over 5 seconds in the <canvas> box. But all I am getting is a black canvas box.

All "//" and "NOTES" are IMPORTANT!

<html>
<head>
</head>
<body>

<canvas id="myCan" style="background: black;" width=720 height=420>
</canvas>

<script>

var canv = document.getElementById('myCan');
var ctx = canv.getContext('2d');
var t = 500; // time iteration

function draw() { // - - draw
ctx.beginPath();

c1x.canv.width*Math.random(); // bezier control 1 NOTES: original code has height ... so try please with your solutions
c1y.canv.height*Math.random(); // bezier control
c2x.canv.width*Math.random(); // bezier control 2 NOTES: original code has height ... so try please with your solutions
c2y.canv.height*Math.random(); // bezier control
x.canv.width*Math.random(); // random point
y.canv.height*Math.random();
x1.canv.width/2; // mid-point
y1.canv.height/2;

ctx.moveTo(x1, y1); // starting point
ctx.bezierCurveTo(c1x, c1y, c2x, c2y, x, y); // bezier curve
ctx.closePath();

ctx.lineWidth = Math.random()*20;
ctx.strokeStyle = hsl(' + Math.random()*360 + ', 50%, 50%); // color of bezier beam
ctx.shadowColor = 'white';
ctx.shadowBlur = Math.random()*50;
ctx.stroke();
ctx.strokeRect(c1x, c1y, 1, 1);
ctx.strokeRect(c2x, c2y, 2, 2);

}

draw();
setInterval(draw, t); // internal timer

setInterval(function() {ctx.clearRect(0, 0, canv.width, canv.height)}, 10*t);
// 10 shapes, '10*t
// 9 shapes, 9*t etc.

</script>

</body>
</html>

That is all.
Thank you.
