I’ll use an
for this example; of course, you’re welcome to change this out for a if you prefer. They are very useful! C335 310, 335 230, 335 230 The number-one reason I use GSAP has to do with cross-browser support for SVG transforms. SVG also makes an excellent tool for creating banners. functions. To begin, we are going to add two more functions to our graphic, function first. There are SVG attributes to control how your SVG graphics respond to resizing. Be sure to checkout SVG transformation attributes, too—and how GSAP can tween them! In part 2, I’ll show you how to animate the drawing of the path strokes. Scalable Vector Graphics (SVG) is an XML-based markup language for describing two-dimensional based vector graphics. the browser is using. function yet but, it simple changes the values instantly, instead of animating them over time. Animating SVG path segments. You don’t want the red button operational until the portafilter is locked in position. In short we will animate Ihatetomatoes logo to look exactly like my YouTube introduction clip.. Here’s the final result. 26 Oct 2015. If … VIEW DEMO →. Convert this red rectangle to a clipping path using and tags. You can add SVG images to web-pages in various ways; for this task, you’ll use inline SVG—that is: writing the SVG code in a pair of tags, among the HTML. Professional-grade animation for the modern web. For now, you pass an array of coordinates, though I wouldn't be surprised if in the future, GSAP added the ability to use an SVG path itself as the definition for the movement. What is GSAP? Hop into your vector software and create any path of your choosing. The Z command closes the path so that the outline of the cup is complete. There are several SVG tags for drawing 2D primitive shapes, including tags for lines and polygons. You’re ready to apply some interactivity and animation to the SVG graphic. When you click the start button, the gsap.to() line tweens the y position of the #cuplevel clipping path, moving it upward to a new y-coordinate of -60 over a duration of 2 seconds; on completion, the callback function will run a deactivateButton() function. Additionally, add a clip-path="url(#cupmask)" attribute to the brown mug—this will apply the relevant clipping path by referencing the id attribute of the opening tag: Now that the clipping path is applied (Figure 11), all you see is the brown coffee showing through: But, the clipping path is currently sitting at the full position. Create a new layer in Framer that will be a container for the SVG, add HTML to that layer with “layer.html = ” and use triple quotes so that nothing breaks up the SVG code. I’m not going to explain GSAP’s API here (see the getting started article for that), but I’ll offer a few SVG-related tips. Then have to address some scaling issues with our SVG paths. For the other ways, refer to the MDN documentation on adding SVGs to web-pages. So, let’s try to play the animation only on hover by adding this: svg:hover .m-left { animation: 2s moveX alternate infinite; } I have been working on a tool that allows to animate the SVG path strokes in a configurable way. We will use the deconstructing trick with the SVG paths again. Let's reorder the animateIn function and change some values to get out animateOut function. We can use two functions called. Well, we have to learn to walk before we can run. Demo Code. This example shows what I would like to do. Note how the colour stops ( tags) correspond to the metallic parts in Figure 4, blending from grey to white (#FFF) in the centre (offset="50%") and again to white at the far right (offset="100%"). GSAP's BezierPlugin enables you to animate any object along a complex bezier curve. If you’re not convinced, they list a bunch more reasons on the GSAP website. The button displays above/over the steel surface because the line comes last (Figure 5). You’ll use that id later to animate the portafilter with GSAP. Stable SVG rotation is very cumbersome. + this.removeEventListener('click', dockPortafilter); + this.style.cursor = 'default'; MDN documentation on adding SVGs to web-pages, https://codepen.io/MarioD/post/interactive-hippo-button-tutorial, https://developer.mozilla.org/en-US/docs/Web/SVG/Element, https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute. In short we will animate Ihatetomatoes logo to look exactly like my YouTube introduction clip. Change the y attribute of the cuplevel rectangle to 310, moving it down and emptying the mug: A bit further along, you’ll use GSAP to animate the y-position of the clipping path, moving it upward to create the illusion of a cup filling with coffee. It’s always 395 pixels high. Combining these two properties together will give you an animation that looks like the paths are being "drawn onto" the screen. It’s a convenient mechanism for arranging shapes into groups of your selection so that you can address and manipulate multiple elements at once. I’ve also added a reset button to restart the steps. The is more versatile because you can use it to draw ellipses and circles. In the future you will be also be able to specify an SVG path. In this article we're going to animate an SVG banner using JavaScript. The tutorial assumes that you possess a decent grasp of how HTML and CSS work. However, this is down the line. Created this so I could easily animate along paths created in Illustrator exported as SVG. The result, depicted in Figure 3, is a maroon rectangle with a thick black outline: Most style properties can be applied using inline attributes or CSS. As the GSAP developers put it—. For a challenge, see if you can add a stream of coffee, from the portafilter to the cup, while the cup is filling up. The magical "align" feature bends coordinate systems and really sets it apart. Add a portafilter (that handle thing with the coffee grounds in it), using a group that’s composed of a and a tag: Note that the opening and closing tags wrap the shapes comprising the portafilter; the group also has an id of "portafilter". There are no more steel elements to add to the espresso machine. I'm trying to create a wave effect with GSAP library and SVG. The difference is that the l point is positioned relative to its preceding point. In the second version, the l command (lowercase) draws a line that ends 130 pixels to the right of (335 230) and 0 pixels above/below it. The easiest way to get transformations to work relative to the path's center is to either: Define the path so that it is centered around the (0,0) point; or; Wrap the path in a element, and then translate it so it is centered on the (0,0) point of the element's coordinate system. In addition to the attributes for setting the x, y, width, and height values, there are rx and ry attributes for making the corners round. You can even edit the path in-browser using MotionPathHelper! // Gets the CSS values used by the browser, // @param {DOM Node} elem - The element whos styles you want, // @param {string | string[]} styles - The CSS properties needed, // @returns {any[]} An array of strings and/or numbers, // Create an array to hold the requested results, // Loop over each style requested and all the value to the result, // Our path wraps around our graphic making. Now replace the alert() line with three new lines: Click the portafilter to move it into position above the cup. Paste the SVG code within the two sets of triple quotes. Animate the mask path and the reveal path. Let's reorder the, function and change some values to get out, /* The same vas the animateIn function */, The animate out value's are the values used for the. The process is very similar for SVG, except that you use createElementNS() instead. I won’t go into much detail about JavaScript—just enough to add some event listeners and manipulate SVG elements with GSAP. A clipping path is a vector shape used to cut out a 2D image, a bit like a stencil. Increasing the x-value moves the rectangle to the right; increasing the y-value moves it down. Our animateIn function will be similar to the applyStyles and applyData functions. I’ve styled the path using the stroked class, so it has a thick black stroke; the fill is a semi-opaque, blue-ish colour. By animating the content of SVG images, you can create appealing animations that look great on all screen resolutions. Of course, you can combine other JavaScript with GSAP, like methods for creating new SVG elements dynamically. In other words, you can address elements as you might in HTML, add event listeners, and so on. Clipping paths are a handy way to clip/mask off parts of objects you want to hide. It would be very distracting and annoying to use on a site with some nearby content. The visual result is exactly the same as the first version. I’ve set the duration of the following animation quite high so you can easily see the masked element rotate as it … I’ve used the viewBox attribute to specify the visible boundaries of the drawing area, and some inline CSS for a max-width of 800px. You’ll need some open paths with a stroke to make this work. We will begin by getting a reference to all the elements that will be animated. Paths can be tricky to get right by hand-coding coordinates, but you can always use Inkscape, Illustrator, or some similar software if you prefer visual tools. For the red button, add an ellipse line to the end of your SVG code: SVG reads from top to bottom, drawing each shape as it moves down the code. If we save the JS file, refresh the browser or reload Caspar, run update with our data, and then run play we should see our graphic animate in. Click the green "Get GSAP Now" button at greensock.comfor more options and installation instructions, including CDN URLs for various plugins. In this tutorial, you’ll create an interactive espresso machine using SVG, JavaScript, and the GSAP library for animation. The HTML includes a link in the to (a CDN-hosted) GSAP library: Add some CSS to the internal style sheet (within the
