GSAP Bezier Curve Viewer

I've been working with bezier plugin quite a bit recently and made a tool to help visualize the curves as creating them blind is no fun! At its heart it's just this function, which should work to visualize any tween (uses jQuery):

let visualizeTweenMaxBezier = (tween, steps) => {
    for (let i = 0; i < steps; i++){

        tween.progress(i/steps);

	$("body").append("<div id='point" + i + "'></div>");

	$("#point"+i).css({
	    position: "absolute",
	    width: "2px",
	    height: "2px",
	    "background-color": "#7F7F7F",
	    top: tween.target.css("top"),
	    left: tween.target.css("left"),
	});
    }
    tween.restart();
}

Currently it generates code based on screen pixel values, if people are finding it useful though I might update it to generate code based on screen percentage, or percentage positions within the containing element. 

 

Happy coding!
