    I have an animation that draws a progressively increasing circle on the canvas until it occupies the entire canvas: const maxRadius = Math.ceil( Math.sqrt(canvas.width ** 2 + canvas.height ** 2) / 2 ); const centerX = canvas.width / 2; const centerY = canvas.height / 2; let radius = 5; function animate() { if (radius >= maxRadius) { canvas.remove(); return; } context.beginPath(); context.arc(centerX, centerY, radius, 0, Math.PI * 2); context.closePath(); context.fill(); radius += 5; requestAnimationFrame(animate); } animate(); And I tried to rewrite it using GSAP but it doesn't work: const maxRadius = Math.ceil( Math.sqrt(canvas.width ** 2 + canvas.height ** 2) / 2 ); const centerX = canvas.width / 2; const centerY = canvas.height / 2; let radius = 5; gsap.to({ radius: maxRadius }, { duration: 1, radius: maxRadius, onUpdate: () => { context.beginPath(); context.arc(centerX, centerY, radius, 0, Math.PI * 2); context.closePath(); context.fill(); }, onComplete: () => { canvas.remove(); }, ease: "power1.inOut" }); Please help me

    Hi there, I would like to have the same effect as on this tutorial: https://codepen.io/PointC/pen/c07761a17f94434f1229e11e798f1a3d Everything is going well, except the drawing of the dashed line. I think I took all the necessary information, and even when I'm copying the code from codepen, the dashed line will not show up. If is remove the part 'mask="url(#theMask)"', the dashed path is showing up. Can somebody please help me? Thanks in advance! Below the result of my code:

    Draw line from Clicked element to point

    Tanken Bak posted a topic in GSAP

    Hello, Im trying to create click points on image/svg, that will animate line and point to another element point. As on image example if line is on building 1 and some one click building 2 or 3, line will go to clicked building. Best wil be if it could move just ending point from one to another position, transforming whole line That's my pen https://codepen.io/isuke01/pen/yLyyeyb but nothing exacting so far, I just create clicking area with callback, but I have no idea how to make this to work as it should. Thanks for any help

    Draw SVG - Circle changes direction

    smallio posted a topic in GSAP

    Small issue with my circle here, it works the first time on hover (in & out) and then changes direction. Any ideas why it breaks after the first hover? It should look like this. Many thanks, Smallio

    How to use Draw SVG Plugin

    Tamas posted a topic in GSAP

    I have simple question. When I going to use the Draw SVG Plugin does it work like, that I have a svg illustration and I drag it into the plugin and the plugin will create the path code and animation as well? The plugin automatically convert the svg into js path codes? So I don't need to write the illustration lines in js? I'm quite beginner so hope it's clear what is my question! Thanks in advance for all advice

    Draw Svg polygon

    335 posted a topic in GSAP

    Hello! I am trying to make an animated SVG of a complex map. I have over 120 elements in my animation. Most of these are paths but some of them are also polygons (circular). Here's a CodePen: http://codepen.io/i76/pen/vgwKKX I am a JavaScript novice. I searched this forum and found a script (in Carl's post) which allows me to draw a path- var orig1 = document.querySelector('#lineAB'); var obj1 = {length:0, pathLength:orig1.getTotalLength()}; orig1.style.stroke = '#f60'; var t1 = TweenMax.to(obj1, 10, {length:obj1.pathLength, onUpdate:drawLine1, ease:Linear.easeNone}) function drawLine1() { orig1.style.strokeDasharray = [obj1.length,obj1.pathLength].join(' '); } However, this does not work with polygons. My guess is that there is not built-in polygon.Length object in JS. I have found this function on another forum that would measure the length of a polygon but I am not sure how to implement it- getPolygonLength:function(el){ var points = el.attr('points'); points = points.split(" "); var x1 = null, x2, y1 = null, y2 , lineLength = 0, x3, y3; for(var i = 0; i < points.length; i++){ var coords = points[i].split(","); if(x1 == null && y1 == null){ if(/(\r\n|\n|\r)/gm.test(coords[0])){ coords[0] = coords[0].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[0].replace(/\s+/g,""); } if(/(\r\n|\n|\r)/gm.test(coords[1])){ coords[0] = coords[1].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[1].replace(/\s+/g,""); } x1 = coords[0]; y1 = coords[1]; x3 = coords[0]; y3 = coords[1]; }else{ if(coords[0] != "" && coords[1] != ""){ if(/(\r\n|\n|\r)/gm.test(coords[0])){ coords[0] = coords[0].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[0].replace(/\s+/g,""); } if(/(\r\n|\n|\r)/gm.test(coords[1])){ coords[0] = coords[1].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[1].replace(/\s+/g,""); } x2 = coords[0]; y2 = coords[1]; lineLength += Math.sqrt(Math.pow((x2-x1), 2)+Math.pow((y2-y1),2)); x1 = x2; y1 = y2; if(i == points.length-2){ lineLength += Math.sqrt(Math.pow((x3-x1), 2)+Math.pow((y3-y1),2)); } } } } return lineLength; } If it doesn't take very long would anyone be able to include the above function into the snippet above so I have a way of animating the polygons as well? Many thanks in advance!

    Draw highlight effect.

    the-creature posted a topic in GSAP

    Quick question. I was wondering if is possible to create an highlight effect in top of 2 draw canvas images. I'm creating a beaker with a back and front image. I would like create a highlight effect. Any codePen or tutorial about it? or this is not possible with GSAP?
  9. ddesilva
    Hi, I urgently need a way to draw say dots along an entire path of a TimelineMax. The path does not need to animate. It just needs to be drawn initially. Can anyone point me in the right direction? ANy help appreciated. Sample timeline: //create timeline self.llnTimeline = new TimelineMax({ delay: 1, smoothChildTiming: true, timeResolution: 0, onUpdate: function() { } }); self.llnTimeline.seek(0); self.llnTimeline.add(TweenMax.to(self.llnPlane, 12, { left: 359, top: 998, ease: Linear.easeNone }), 0); // 1 self.llnTimeline.add(TweenMax.to(self.llnPlane, 12, { ease: Linear.easeNone, css: { bezier: { autoRotate: true, type: "thru", values: [{ left: 338, top: 1099 }, { left: 257, top: 1114 }, { left: 47, top: 945 }, ] } } }), 12); // 2 self.llnTimeline.add(TweenMax.to(self.llnPlane, 22, { ease: Linear.easeIn, css: { bezier: { autoRotate: true, type: "thru", values: [{ left: 27, top: 836 }, { left: 304, top: -573 }, { left: 379, top: -1045 }, ] } } }), 20);

    Draw an oblique line with TweenMaxJS

    FracArt posted a topic in GSAP

    Hi everybody, for a personal project I would like to build an oblique progress bar. So, my first question is: Is there a way to create dynamically and easily a Line object with Tweenmax.js? For the moment I just resize the width of a rectangle shape like this : http://jsfiddle.net/FracArt/6GJ67/2/ Which actually works! But seems a bit "hacky". Second question, as you can notice on the jsfiddle file I tried to build an oblique progress bar on the same principle. However, when I rotate the rectangle a gap appears between the initial and final position of the bar. So do you have an idea of how I can correct that without doing some geometry calculations? (maybe a transform-origin property on the css?)

    un4given posted a topic in GSAP

    I cant seem to get accsess to the BezierPlugin, I get a undefined error. My aim is to draw the line my object moves along using bezierThrough, do you know of any simple tutorials/examples of this? I found a few but they are quite confusing.
