  1. Hey guys, so basicly i want to trigger an animation when the visitor scrolls down to the place the animation is located. how would i go about doing it? this is the code i want to trigger: <script> //we'll use a window.onload for simplicity, but typically it is best to use either jQuery's $(document).ready() or $(window).load() or cross-browser event listeners so that you're not limited to one. window.onload = function() { var sponsor = document.getElementById("sponsor"), funktioner = document.getElementById("funktioner"), patenter = document.getElementById("patenter"), butik = document.getElementById("butik"); godtdesign = document.getElementById("godtdesign"); direktesalg = document.getElementById("direktesalg"); brick1 = document.getElementById("brick1"); brick2 = document.getElementById("brick2"); brick3 = document.getElementById("brick3"); brick4 = document.getElementById("brick4"); brick5 = document.getElementById("brick5"); brick6 = document.getElementById("brick6"); brick7 = document.getElementById("brick7"); brick8 = document.getElementById("brick8"); brick9 = document.getElementById("brick9"); brick10 = document.getElementById("brick10"); brick11 = document.getElementById("brick11"); brick12 = document.getElementById("brick12"); brick13 = document.getElementById("brick13"); brick14 = document.getElementById("brick14"); brick15 = document.getElementById("brick15"); brick16 = document.getElementById("brick16"); brick17 = document.getElementById("brick17"); brick18 = document.getElementById("brick18"); brick19 = document.getElementById("brick19"); brick20 = document.getElementById("brick20"); rbrick1 = document.getElementById("rbrick1"); rbrick2 = document.getElementById("rbrick2"); rbrick3 = document.getElementById("rbrick3"); rbrick4 = document.getElementById("rbrick4"); rbrick5 = document.getElementById("rbrick5"); rbrick6 = document.getElementById("rbrick6"); rbrick7 = document.getElementById("rbrick7"); rbrick8 = document.getElementById("rbrick8"); TweenLite.to(godtdesign, 1, {opacity:1.0, delay:1.0}); TweenLite.to(direktesalg, 1, {opacity:1.0, delay:2.0}); TweenLite.to(butik, 1, {opacity:1.0, delay: 4.0}); TweenLite.to(patenter, 1, {opacity:1.0, delay:3.0}); TweenLite.to(funktioner, 1, {opacity:1.0, delay:2.0}); TweenLite.to(sponsor, 1, {opacity:1.0, delay:1.0}); TweenLite.from(brick1, 0.2, {y:-400, opacity: 0.0, delay:0.0, }, 0.05); TweenLite.from(brick2, 0.2, {y:-400, opacity: 0.0, delay:0.2, }, 0.05); TweenLite.from(brick3, 0.2, {y:-400, opacity: 0.0, delay:0.4, }, 0.05); TweenLite.from(brick4, 0.2, {y:-400, opacity: 0.0, delay:0.6, }, 0.05); TweenLite.from(brick5, 0.2, {y:-400, opacity: 0.0, delay:0.8, }, 0.05); TweenLite.from(brick6, 0.2, {y:-400, opacity: 0.0, delay:1.0, }, 0.05); TweenLite.from(brick7, 0.2, {y:-400, opacity: 0.0, delay:1.2, }, 0.05); TweenLite.from(brick8, 0.2, {y:-400, opacity: 0.0, delay:1.4, }, 0.05); TweenLite.from(brick9, 0.2, {y:-400, opacity: 0.0, delay:1.6, }, 0.05); TweenLite.from(brick10, 0.2, {y:-400, opacity: 0.0, delay:1.8, }, 0.05); TweenLite.from(brick11, 0.2, {y:-400, opacity: 0.0, delay:2.0, }, 0.05); TweenLite.from(brick12, 0.2, {y:-400, opacity: 0.0, delay:2.2, }, 0.05); TweenLite.from(brick13, 0.2, {y:-400, opacity: 0.0, delay:2.4, }, 0.05); TweenLite.from(brick14, 0.2, {y:-400, opacity: 0.0, delay:2.6, }, 0.05); TweenLite.from(brick15, 0.2, {y:-400, opacity: 0.0, delay:2.8, }, 0.05); TweenLite.from(brick16, 0.2, {y:-400, opacity: 0.0, delay:3.0, }, 0.05); TweenLite.from(brick17, 0.2, {y:-400, opacity: 0.0, delay:3.2, }, 0.05); TweenLite.from(brick18, 0.2, {y:-400, opacity: 0.0, delay:3.4, }, 0.05); TweenLite.from(brick19, 0.2, {y:-400, opacity: 0.0, delay:3.6, }, 0.05); TweenLite.from(brick20, 0.2, {y:-400, opacity: 0.0, delay:3.8, }, 0.05); TweenLite.from(rbrick1, 0.2, {y:-400, opacity: 0.0, delay:0.0, }, 0.05); TweenLite.from(rbrick2, 0.2, {y:-400, opacity: 0.0, delay:0.2, }, 0.05); TweenLite.from(rbrick3, 0.2, {y:-400, opacity: 0.0, delay:0.6, }, 0.05); TweenLite.from(rbrick4, 0.2, {y:-400, opacity: 0.0, delay:0.8, }, 0.05); TweenLite.from(rbrick5, 0.2, {y:-400, opacity: 0.0, delay:1.0, }, 0.05); TweenLite.from(rbrick6, 0.2, {y:-400, opacity: 0.0, delay:1.2, }, 0.05); TweenLite.from(rbrick7, 0.2, {y:-400, opacity: 0.0, delay:1.4, }, 0.05); TweenLite.from(rbrick8, 0.2, {y:-400, opacity: 0.0, delay:1.6, }, 0.05); } </script> thank you! - Jonas
  2. I'm trying to set up my page such that my document's scroll behaves exactly like a 'scroll' draggable. What I'm really after is document scrolling that snaps to certain areas of the page, but with all the silky physics of Draggable — I basically want my scroll events to act just as if they were throws. For example, look at GreenSock's own "scrolly knob" demo. When the scroll area is dragged, or when the knob is turned, the scroll velocity is animated smoothly to a stop at one of the snap points. But when the content is manually scrolled by the user, there's no inertia or snapping. What I want is for mouse scrolling to behave just as the other scroll methods do. Any help with achieving this effect would be greatly appreciated!
  3. Hello, i just started using GreenSock and from the examples I'm very impressed Now i try to implement a prototype and have run into a problem. I have a div consisting of several divs laid out horizontally. This div is wider than the screen and i want it to move from left to right and back again. This i got to work. If the user starts scrolling manually, the animation should stop (works too) and the user should be able to scroll the div normally. Here is where i ran into a problem. Let's say the div scrolls to the left, then everything that goes offscreen is lost to the manual scroll and can't be reached. I'm not sure how to explain it, please see the attached codepen.io I'd be grateful for any advice. Kind Regards Nadja
  4. Hello, I can not figure out what would be the best way to accomplish this: I would liek to simulate a continous text scroll on mobile device. I made a PNG that has some horizontal lines which look like text paragraphs. I would like to move this PNG from bottom to top, simulating a scroll on mobile device. The animation runs in loop and I get an empty screen between iterations. I would like the same PNG to start moving into screen while the previous moves out so it looks like a continous scroll. What is the best way to animate this? Shold I use the same image twice on two separate tweens? Thank you. Alin
  5. Hey there everyone in the community, I am new here and firstly I gotta say to the GSAP Dev's...GREAT JOB, amazing plugin. But, even with its ease of use, I found it hard to aquire my desired effect. What I iam to accomplish, is to initiate a text animation I have used from your examples in the ZIP file, upon scrolling over the desired DIV. As it sits, GSAP uses: $(window).load(function() { to initiate the animations declared in the JS. Since I do not ant the animation to instantly start on page load, and I want it to start once scrolled over, this does not work for me. Now, I have tried the simple and powerful: $(window).on('scroll', function() { to try to reach my results. Hoever, even though it works upon scrolling over. It also works upon page load. Meaning, that lets say Im at the point of origin where the animations take place on the page. I refresh my page in that spot and the GSAP takes place right away. I move out of that space to another point on the page and scroll back to the animation area, and the letters in the animation are there as if the animation has finished (which it has because it still initiated on page load somehow) BUT then... the animation occurs upon scrolling over, but, get this...the animations from the scroll, take place underneath the completed animation that occured on page load. It is very hard to explain but you can evaulate my code below, and maybe help me to get the animation to only take effect when it is scrolled over. Here is my code: $(window).load(function() { var logo = $("#logo"), progressValue = $("#progressValue"), totalProgressValue = $("#totalProgressValue"), timeValue = $("#timeValue"), totalTimeValue = $("#totalTimeValue"), restartBtn = $("#restartBtn"), txtContainer = $("#txtContainer"), tl, progressSlider, totalProgressSlider, txt; /* Build DOM Elements*/ function splitText(phrase) { var prevLetter, sentence, sentence = phrase.split(""); $.each(sentence, function(index, val) { if(val === " "){ val = " "; } var letter = $("<div/>", { id : "txt" + index }).addClass('txt').html(val).appendTo(txtContainer); if(prevLetter) { $(letter).css("left", ($(prevLetter).position().left + $(letter).width()) + "px"); }; prevLetter = letter; }); txt = $(".txt"); } /* Build Timeline */ function buildTimeline() { //note this timeline uses 3D transforms which will only work in recent versions of Safari, Chrome, and FireFox. IE10 will support 3D transforms as well. All other browsers simply will not show those properties being tweened. TweenLite.set(txtContainer, {css:{perspective:500}}); tl = new TimelineMax({onUpdate:updateUI, repeat:2, repeatDelay:1, yoyo:true}); tl.from(logo, 0.5, {left:'-=60px', ease:Back.easeOut}); tl.staggerTo(txt, 0.6, {rotationX:"360deg", color:"858585", transformOrigin:"50% 50% 10"}, 0.02); } /* callbacks */ function updateUI() { //change slider value progressSlider.slider("value", tl.progress() *100); totalProgressSlider.slider("value", tl.totalProgress() *100); //update display of values progressValue.html(tl.progress().toFixed(2)); totalProgressValue.html(tl.totalProgress().toFixed(2)); timeValue.html(tl.time().toFixed(2)); totalTimeValue.html(tl.totalTime().toFixed(2)); } function init() { splitText("CONTACT US"); buildTimeline(); //show the demoBackground div after DOM is ready and all images loaded TweenLite.set($("#demoBackground"), {visibility:"visible"}); } init(); }); If anyone sees what I am doing wrong here, or can help...please do. I am not very new to JS or jQuery but am very new to GSAP. So any help is appreciated. Thanks in advance! EDIT: Here is my HTML: <div id="demo"> <h1 id="txtContainer"></h1> </div> </div> Thanks again! ~Jason of AJADMIN Websites
  6. Hi there, I have seen many sites that let you smoothly scroll a webpage up and down when you click on navigation buttons. I was wondering how I would go about this with the new Greensock JS. I have had no luck, and also all the examples I have looked at scroll to the location of a div. Is there no way I can just set a value or height property instead. Like scrollTo 1000px. I already have my function set up so I just need the animate scroll code. $('#box1').click(function(){ // Code goes here }) Thanks for your help Will P.s. Sorry I just moved this post to here, realised I posted this in the wrong area of the forum before.
  7. ThrowProps and Blitmask really do work well together for scrolling, but most of my views have too much interactivity for Blitmask to be useful. The BlitMask would need to be updated with a forced recapture of the Blitmask each time any change is made to the view, and this is taking about 500ms, which interferes with a smooth scroll. Is there an example for using ThrowProps in a Scroller without using BlitMask?
  8. Hello people! I have a <nav> with absolute position and inside of it some links <a>. After some scrolling I change its position to fixed to stick it at the top. (using stickOnScroll plugin) At the beginning I bind a mouseover to tween color of the text in <a> and works fine, but when I change it to fixed position the tween disappear. Thank you so much! <nav class="full-width" id="home_menu"> <ul class="container"> <li><a href="javascrip:void(0)">slim center</a></li> <li><a href="javascrip:void(0)" id="menu2">tratamientos</a></li> <li><a href="javascrip:void(0)">estilo de vida</a></li> <li><a href="javascrip:void(0)">por un méxico más sano</a></li> </ul> </nav> nav#home_menu{ position: absolute; height: 60px; top: 700px; width: 100%; border-top: solid 1px white; border-bottom: solid 1px white; } nav#home_menu ul{ min-height: 60px; height: 60px; top:0; width:1200px; left:50%; ; } nav#home_menu ul li{ display: inline; float: left; } nav#home_menu ul li a{ display: inline-block; margin-top: 23px; width: 295px; text-align: center; } $("#home_menu").stickOnScroll({ topOffset: 0, setParentOnStick: true, setWidthOnStick: true, onStick: onSticknav }); function onSticknav() { $('#menu2').bind('mouseover', overMenu); } function overMenu(e) { TweenMax.to($(e.currentTarget), .4, {color:"#009aff"}); }
  9. Hi there, i'm trying to do one of those animations on the header as you scroll down. I want it to be a very nice and smooth transition. I'm trying to do in such a way that i could easily re-use the code in different projects, just changing the timeline animation. Basically, when you scroll down 50px, an animation would play instantly, at the moment i'm adding a class "sticky" to my header, so i can control the position thru css, but i can't get the animation working. I'm sure there's something missing on my code, just can't figure out what it is. $(function() { var header = $(".header"); $(window).scroll(function() { var scroll = $(window).scrollTop(); if (scroll >= 50) { header.removeClass('not-sticky').addClass("sticky"); console.log("sticky") } else { header.removeClass("sticky").addClass('not-sticky'); console.log("notsticky") } }); }); var headerAnim = new TimelineLite({}); headerAnim.to(".sticky", 1, {css:{background:'#ccc'}, color:'#fff', ease:Back.easeOut}); //>> animate logo in, etc
  10. Is it possible to use a Superscrollorama object to control multiple timelines? My code: http://codepen.io/vincentccw/pen/AwIbx/?editors=111 RIght now the box1 class is animating as intended, but I'm only allowed to animate one box at a time, if I add another timeline below it, the whole animation stop working. Is there a better way to add multiple animation timelines or do I need to create multiple scrollorama object to hold individual timeline>
  11. Hello everybody, so far I am loving this plugin it is a great tool and this site is a great resource and I appreciate all the work that has been done in delivering such a great tool. I have a timeline that I created. The timline is not really that important. Just in case though: var tweenArticle = new TimelineMax() .from($('header.food_header > hgroup'), 3, {opacity:0, top:'-40px', ease: Power4.easeOut},0) .from($('article.food > section > summary > p'), 3, {opacity:0, top:'40px', ease: Power4.easeOut},0); This is the site I am trying to put it on: http://webshowcase.tk/wp1/?page_id=114 This is a wordpress site and what I am trying to do is affect every post on the page. When The article is in the viewport I would like to start animating just the elements in that article and if possible reverse but reverse is not super important at the moment. I can't seem to figure out how to get my timeline to play when the article is in the viewport. Any help would be greatly appreciated. Thank you.
  12. Hi, I'm trying to create a similar website to http://www.nouvelleoctavia.fr whereby as you scroll the content and imagery increase in size, fade in and fade out as if you are passing through it. I'm a newbie to GreenSock and I am having trouble understanding how it works. I'm currently trying to get a simple coloured div rectangle that is in the centre of the screen to increase and "pass through" as I scroll but it is not working. Any help would be most appreciated in getting me started. Thanks
  13. Hi All, I have a site where I have a horizontally styles un-ordered list (<ul>), my site dynamically adds items to the list based on user interactions. For each new item in the list, I have applied a Draggable.create call to make them draggable in the Y axis (vertical), I also apply an animation Tween on the item so it bounces into place. This all works fine! Im using this code for that: //add to the UL $(".cardList").prepend(newDiv); //animate the card into place TweenLite.from(newDiv, 0.5, { y: -250, ease: Elastic.easeOut }); Draggable.create(newDiv, { type: "y", onDrag: function () { //my code... }, onDragEnd: function () { //my code... } }); However, when there are a lot of items in the list, I would like to scroll the list horizontally, so I wrapped up my list into a DIV container and called: var scroller = new Draggable("#cardsContainer", { type: "scrollLeft", edgeResistance: 1.0 }); ...which 'kind of' works. I currently have 2 issues: 1) I can add a new item into the list and I can see that the scrollbar on the scroller increases, but from time to time, the scroller "snaps back" prematurely, so effectively you can never scroll to the end of the list. It simply stops scrolling, it looks like the animation I am using to add the new items to the list could have some effect on the calculation of the width of the scroller? 2) When I click and drag the scroller (when it does work), the items in the list which can scroll vertically move slightly up/down, can I have some kind of check to see if the user is scrolling left/right and NOT enable the vertical scroller based on some threshold? I hope that makes sense
  14. Hey, when I zoom in it zooms to the top left. I can scroll back to where I was centered, but is there a way to change the registration point? When I zoom in to a specific spot by moving top:-x, left:-x it crops off the top left. Would a better way, than changing the registration point, be appending the bounding box? I tried a couple suggestions with adding draggable, but in all the demos it required something for only paid members. Any ideas would be greatly appreciated. Thanks!
  15. Hello All, I am developing an app on android using phone gap. I am using timelinemax for animation. My animation is like this : one object is animating along with scroll animation. Animation works fine after scroll is completed. when both run simultaneously then object animation is poor. Is there any workaround for this ? Android Tested : 4.0 to 4.2 My second concern is that how we can achieve more smooth animation by force3D = TRUE or by Tweenmax.set(obj,{z:0.1}); ? Any help would be appreciated.
  16. Hi guys, firstly, let me thank you for this fantastic animation platform. Discovering it was simply jaw-dropping experience that changed my life as a developer. I am now playing around with page that will have multiple animations triggered on particular scroll position. I decided to not use any parallax plugins that work on mobile, because they appeared to be slow. Basically, I want to animate some DOM elements when they come in to the view. I tested it in all browsers and it works fine, even on iOS, but sometimes it is acting a bit weird. I have problems only on iOS. I haven't tested any android, i don't have any. When you scroll slowly to the desired element, it animates just fine. But sometimes when you scroll faster, it appears in final position, but without an animation. Sometimes just part of an animation happens. I would like to understand whats going on there. Can you help me please, or at least point me to the right direction? I am using latest version of GSAP, tested on iPhone 4 with iOS 6.1.3 and iPad 3. I was able to recreate the issue on iOS simulator as well. I am attaching example code. Many thanks! scrolltest.zip
  17. I'm trying to use Superscrollorama to animate some stuff on a webpage. The content only animates inside a specific div on the page, so I want the user to be able to scroll the page normally until that section is reached, then pause the page scrolling while keeping the scrollable animation. Once the animation has completed, they would continue scrolling down the page. I've tried using the pin functionality, but my div that contains the animations stays put while the rest of the page still scrolls. So I set it to pin the whole content of the page, and adjusted the offset so it wouldn't start until the user got to the animated section. This seems to be the right direction, but when I get to that scroll point, it jumps me back to the top of the page for some reason. If I jerk the scroll bar down past that point it seems to sort of work. Here's my code I have thus far: var controller = $.superscrollorama(), animatedContent = $('#content'); controller.pin(animatedContent, 1000, { anim: (new TimelineLite()) .append( TweenMax.to($('#water_color'), .5, {css:{height:0}}) ), offset: 400 }); And the HTML looks like this <body id="whats_new" includeLocalCSS="true" includeLocalJS="true" class="innovation reflex wide"> <section class="hero_area"> <div class="image_background"> <img src="fake.jpg"> </div> <div class="hero_overlay"> <div class="container_12"> <section class="demo top_blue_border grid_12"> <div id="animated_content"> <div id="text_intro" class="animation_copy"> <h2 class="type-light">Engineered to<br>Move with You</h2> <div class="top_blue_border"></div> <p>blah blah</p> </div> <div id="water_color"> <img id="blue_bar" src="sample.png" alt=""> </div> <div id="base_image"> <img src="sample.jpg"> </div> </div> </section> </div> </div> </section> </body> The animated content div is where the animations actually happen and are about 600 pixels down the page.
  18. I have created a sample for it: http://codepen.io/vincentccw/pen/vLIGh If you look into my javascript panel I have 2set of codes, one using jquery and GSAP another is just jquery(comment out). The code will be active once use scroll down using mouse wheel. My question is how do I use scrollTop but completely in GSAP? As I think GSAP is more readable and animate faster and most importantly I can set up more complex animation at the same time.

    disable reverse

    Hello, i am new to superscrollorama. I want to disable an animation when you scroll up. I found the code on the website but it doesn't work for me: The 5th parameter is reverse, which you can use to disable reverse animation. controller.addTween('#fade', TweenMax.from($('#fade'),.5,{ css:{opacity:0}}), 200, false); // prevent backwards animation of the element What am i doing wrong? Frans
  20. Hello again, I'm now moving on to the menu. How do I setup the menu (styled it etc..), so what I want is that once you click on a menubutton it auto scrolls down to that page/section. And my question is. How do I do that? Because when I look at the demo of this I don't see any demo with an actual functioning menu. There is a lot about effects and animations, but nothing in it about how to make all of that work with a navigation also. Does anyone got some kind of tutorial on 'How to make a menu that scroll to page/section'? Maybe there is a tutorial somewhere that I have missed?
  21. Hi all! Today I was trying to execute some instructions on manual scroll event, avoiding the scroll animation performed by TweenMax. I attempted to initialize a boolean variable, which is false during the TweenMax animation and is restored to true "onComplete". On $(window).on("scroll") I checked the status of the variable. I found out that a scroll even was triggered even when my status variable was already returned to true: after some tests, it turns out that it's TweenMax itself. I tried on an empty page, reporting the following code in Firebug console, and looks like after the "hi" reported by TweenMax onComplete, another scroll event is triggered. $(window).on("scroll", function(){console.log ("scroll");}); TweenMax.to(window, 1, { scrollTo: { y: 500 }, ease: Linear.easeNone, onComplete: function () { console.log("hi!"); } }); I wouldn't expect this behavior: why does this happen? Thanks in advance! Massi
  22. Hello! First of all: Thank you for your great work! I`m trying to move a dynamic TextField from the bottom of the screen to the top and it works. It runs nice and smoothly on my PC. The problem starts when I run the .swf on a target, which is not as powerful as my developement PC. The text animation becomes quite choppy. I tried several things (cache text as bitmap via BitmapData, using TweenLite and now using BlitMask) to improove the performance and I could manage to get 11-12 FPS on the target hardware. That`s "ok".. but it would be nice to squeeze out some more FPS. Globally I define a Blitmask: var txtMask:BlitMask = null; I initialize it: txtMask = new BlitMask(txtMessage, 0, 680, movieWidth, textAreaHeight,true); ...and start the animation: txtMessage.text = msg; txtMessage.y = movieHeight; txtMessage.height = txtMessage.textHeight + 4; txtMask.update(null, true); TweenLite.to(txtMessage, Number((txtMessage.height + textAreaHeight) / textScrollSpeed), {y:(movieHeight - textAreaHeight - txtMessage.height),onComplete:onTextScrollFinish, ease:Linear.easeNone,onUpdate:txtMask.update,useFrames:false,immediateRender:true}); I also tried to tween the scrollY attribute of the BlitMask, but this didn't change anything (as expected). So I guess I just wanted to ask if someone has an idea how I could further inprove the performance of the TextField animation. Would it help to try the ThrowProps plugin? Thank you for your time
  23. Hello, I'm just starting with TweenLite and I have a very basic question: I tween a movieclip in a mouseup event (it is a simple scroll), using this: TweenLite.to(mc, 2, {throwProps:{x:200, y:0}, ease:Strong.easeOut}); The effect looks good, but I need to limit the movieclip "mc" X. The mc may have a maximum X value of 0, and a minimum of -1500, so I can tween the mc without showing the background under the mc. Is there any way to limit the tween or to stop the tween when the mc reach the limits? Thank you very much.
  24. Hello, I love your products and everything Greensock stands for. Your products are top-notch, and the customer service is as good as the Kinko's customer service is bad. GreenSock customer service is like "Bizzaro Kinko's Customer Service." In other works: GreenSock - "Totes Awesome Sauce" Kinko's - "The Hangover 2 & Indiana Jones 4, kind of awful" I am trying to come up with the most efficient and "zazzy-licious" way to put in the background of one of my website page, the scrolling code that you see on computer screens in the background of movies and tv shows. I'm not sure if I want just pure binary (1's and 0's) or letters and numbers. I figured that I would find about 500 ka-trillion Google results showing different ways of doing this in various languages, but alas, I didn't really find much of anything. I'm using the Greensock Javascript libraries (v.12) and the latest version of Raphael.Js. I don't really need anyone to show me how to do this, by providing a working example (at least, not yet). I'm really looking for a broad outline of the steps I would need to take to accomplish this task in the most code efficient and least taxing burden on the browser way possible. Any help would be greatly appreciated. Thanks, Sweet J
  25. Hello, I have an element whose opacity is being changed based on scroll position. No problem there. When the element is in the scroll range, I want it to loop an animation only while within the scroll position range. The looping the animation part is what I'm having trouble with. I tried calling a function, using onComplete, etc. Here is the timeline: var tlwhoweareGreen = new TimelineMax({paused:true}); tlwhoweareGreen.append( TweenLite.to($("div#whoweare-green"), 1, {css:{opacity:1, autoAlpha:1}}) ); /*I've been trying to append the timeline or call a function here. Once the opacity has been set to 1, I want it to loop back to zero and back to one, infinitely until the the user has scrolled outside the range*/ Here is the scroll function: $(window).scroll(function() { var getVert = $(this).scrollTop(); console.log(getVert); var getHor = $(this).scrollLeft(); function scrollTween(startPoint, endPoint, tweenName, type) { var progressNumber; if(type == 'vertical') { progressNumber = (1 / (endPoint - startPoint)) * (getVert - startPoint); } else if (type == 'horizontal') { progressNumber = (1 / (endPoint - startPoint)) * (getHor - startPoint); } if (progressNumber >= 0 && progressNumber <= 1) { tweenName.progress(progressNumber); } else if(progressNumber < 0) { tweenName.progress(0); } else if(progressNumber > 1) { tweenName.progress(1); } } scrollTween(400, 800, tlwhoweareGreen, 'vertical'); $("div#whoweare-green").css("display", "block"); }); }); </script>
