  1. Hi, Since helping Stefdv in this topic i dug a little more into parallax and scroll controlled Tweens/Timelines, and i dedicated some time to create a tutorial and some code in order to help GSAP JS users to create some apps and web sites using this technique. Is not a lights-out-blow-your-mind type of tutorial, but i just was hoping to help some other users who might want to apply this into their creations. Here you can find the tutorial, as well as the source code and a couple of examples, since i don't have a blog of my own, i'll take the liberty to point comments here, unless the staff says other thing. Since i started with this tutorial i found a lot of things about parallax and because of that i will make a second tutorial which i haven't started yet, but as soon as my schedule allows me to i will write it. I hope you enjoy it, Cheers, Rodrigo.
  2. I am getting this weird error trying to use BlitMask when debugging on my android device: Error #2030: End of file was encountered. And it is coming from this part of the BlitMask code, on TOUCH_BEGIN event (when i put my finger down on the BlitMasked object): /** @private **/ protected function _mouseEventPassthrough(event:Event):void { if (this.mouseEnabled && (!_bitmapMode || (event is MouseEvent && this.hitTestPoint(MouseEvent(event).stageX, MouseEvent(event).stageY, false)))) { dispatchEvent(event); } } When debugging in emulator, the error does not happen, only when debugging on device. Does anyone know how to fix this issue?
  3. Sorry Im a new user of greensock . I want to achieve a 100% screenHeight scroll whenever user scroll until the trigger : ================================================================================ var tween7b = TweenMax.fromTo('#red2', 1, {y: "100%"}, {y: "0%", backgroundColor:'#C74A00', ease: Linear.easeNone}); var tween7c = TweenMax.to('#red2', 1, {y: "-100%", backgroundColor:'#C74A00', ease: Linear.easeNone}); new ScrollMagic.Scene({triggerElement: "#trigger6e", triggerHook: 0.85}) .setTween(tween7b) .addTo(controller); new ScrollMagic.Scene({triggerElement: "#trigger6e", triggerHook: 0.45}) .setTween(tween7c) .addTo(controller) .addIndicators(); ================================================================================== Sometimes its work, but sometimes it failed. I guess its getting confused because of two TweenMax.fromTo affected the same ID ? how could I achieve what I want then? thankyou before
  4. I have a movie clip that I want to drag "scroll left" in 650 pixel increments. I have a movie clip (mc1) that is 650x650px on the stage (embedded within this clip is a symbol (mc2) that is 3250pxs x 650pxs (divided into 5 images) I want to drag through mc1 in 5 swipes revealing each image (650x650) on mc2 //movie clip 1 Draggable.create(mc1, {type:"scrollLeft", edgeResistance:0.5, throwProps:true}); Could you help me with the code that I need to initiate this please, I just need a push in the right direction and away I'll go until the next hurdle. Learning heaps and loving it.
  5. I am doing my first GSAP animation (yay for me)! The div containing the animation is below the screen when the page loads -- both on desktop and mobile. I don't want it to begin animation until the user scrolls to it. I want to verify that, in order to do this, I need to do something like the following: myTimeline.to('body', .5, {scrollTo:{y:250}}); with "250" being the distance of the div from the top of the page. Is this correct?
  6. Hi everyone, hope you are fine ! I come today with a new question about tweenmax. I have a earth to make rotate while the user is scrolling (position fixed). Then the earth has to transform in an other item. Well, after some research on your forum I discovered that you can have something fluent and nice with sprite sheets. and this function : TweenMax.to(obj, 0.2, {x: "-=1194px", ease:SteppedEase.config(3)}); Sooo I have 20 images in my sprite for a width of 7960px. The thing is, when I am rotating while scrolling, I can't do something like : x: "+= scrolling value". If I am not in good proportions the animation is broken. But in the meantime, if I scroll to a maximum position the animation has to be completed before transforming in an other object ! So I decided that each time I scroll, I will send 1194px to x, that correspond to 3 images. But, if you scroll very slowly you won't arrive in the next image's area before the end of spinning animation! Do you have some idea or tips of how I can synchronize tweenmax with a scroll ? I am hesitating about using scroll magic but I am afraid that it will use a huge amount of time to implement / masteries. EDIT: here is a codepen I made. http://codepen.io/anon/pen/VLJWrX
  7. Hello, I am trying to build a UI where two arrows – up and down – control the scroll position. The scroll element is a Draggable. var scroller = $('.scroller.draggable'); Draggable.create(scroller, { type:"scrollTop", edgeResistance:0.75, throwProps:true, onDragStart: function() { Draggable.get(menu).disable(); }, onDragEnd: function() { Draggable.get(menu).enable(); } }); $('.icon-arrow-down').on('click', function(event){ TweenLite.to(scroller, 1, {scrollTo:{y:$scope.yStart}, ease:Power2.easeOut, onComplete:updateYScroll}); function updateYScroll() { console.log(this.scrollY); //$scope.yStart = scroller.scrollY + $scope.yIncrement; } }); But when calling scrollY I always get undefined... Greetings, luneyard
  8. I touched on this in a previous posts but am still to find the perfect solution for mixing Draggable dragging/scrolling with native browser scrolling. 1. Open the attached Codepen 2. Emulate touch events - open Chrome inspector and emulate a device such as a Nexus 5 3. Alternatively view the Codepen on a device 4. Alternatively view the screen cap below Basically, you will see that it isn't possible to scroll the page vertically when the drag starts on the Draggable carousel (blue blocks). I've examined Draggable.js source code but I can't figure out where you the relevant scroll / touch event are being intercepted. Could you point me in the right direction? I know one work around is to use a second Draggable to control vertical scrolling but this isn't an option for us, we need native browser scrolling when scrolling vertically.
  9. Is there a built in option to auto-scroll the container of a draggable element when the draggable is moved beyond the container? I am currently hooking up to the onDrag event and doing thing based on Y pointer. I kinda get the result I want. But still curious if there was a default option provided or anyone else has done it better.
  10. Hi, Can I use greensock for continuous scroll upon keypress + hold Let say I want a page to scroll continuously arrow key down is pressed and stop when release I also checked the doc and faq section and I can't find instruction how to start using gsap. Do you have documentation on getting started? Thanks
  11. Is it possible to have natively vertical scroll elements within a horizontal Draggable element?
  12. Hello i wanna ask for the more experienced userds of GSAP JS: How can i make a window scrollTo plugin go to 100% bottom of the webpage? on jquery i set it as "max", but i wan´t to use only GSAP for animations and jquery for selector and general pourposes tnx for your time.
  13. Does GSAP have built in scroll functionality to trigger animations or do I need to use another library such as ScrollMagic or Skrollr?
  14. I'm working on a site which will use like 7 slides in a kind of stair way. I was now trying to use Draggable for my navigation but I want to prevent the user to get lost. Since you can use type:x or type:y I thought I might get somewhere if I could change that type on the fly after Draggable.create. That doesn't seem to work. Maybe someone knows if that's possible or if I better can look for a solution based on a combination of tweens and scrollTo? To be clear an image attached of the layout. Every screen will cover the entire window.
  15. Hi all, this is my first post on this forum. I am working on a mobile calendar which requires to manage a large horizontal drag area combined to a important vertical scroll for a mobile web application (in webkit browser : Safari / Chrome) You will find a mockup attached to this post in order to understand what i am trying to do. This calendar has : - on left side : a vertical list of people (called "fixedView") - on right side : a vertical list of blocks which has a horizontal scrollview (using Draggable) in order to swich days by using drag gesture on axis : x (called "InnerView") These two sides are embedded in a "mainView" which is the page container for calendar. (Please have a look to attached file). In fact, i am trying to use a horizontal Draggable (InnerView) into a container which has a vertical scroll (mainView) I made a lot of research , check mobile performances (Galaxy S3 mini to iPhone5) and tests to try : "Scroll In Scroll" : Adding a vertical Draggable for mainView + Adding a horizontal Draggable for InnerView it "works badly" but don't know how to control vertical & horizontal in order to "lockAxis"; right now you can do diagonal drag which is not good (and bad perfs of course) moreover : with this method, i removed native scroll (provide by webkit with -webkit-overflow-scrolling: touch; which brings low perfs on vertical scroll => My Conclusions :using Greensock Draggable to manage vertical scroll is not possible cause we have very bad perfs on low devices I have to use native scroll provided by webkit for vertical scroll (best perfs.) and use Draggable for horizontal scroll (in InnerView) only Do you agree ? So, this is the problem i can't resolve : When i create a new Draggable for InnerView (params below) with {type : "x"}, i can't do a vertical scroll anymore (for sure). What i would like to do is to detect when user is doing a horizontal or vertical scroll on InnerView (by a swipe or drag gesture) . If User is scrolling horizontaly => we use Draggable Instance for InnerView only if User starts scrolling verticaly => we use a "prevent default" for Dragable to release touch bind and so let the browser do a native vertical scroll (webkit) So for this 2nd point, i don't know how to do this. (I had a look on google, GSAP forums, Docs...) I tried to bind the event with onDragStart method but didn't get it. Do you this this is the right approach ? I cant use a Draggable instance with {type : "x,y"} because it would mean that only "InnerView" will scroll vertically but in our case we need to scroll the entire mainview (which include FixedView + InnerView => so the mainView I had a look to "scrollLeft" and "scrollTop" properties and several code pens but i am still blocked. Hope my post is understandable; if you need more details, do not hesitate. Here Draggable Instance for InnerView : innerView = Draggable.create(innerViewEl, { type : "x", bounds : targetStageEl, throwProps : true, force3D : params.stage.force3D, edgeResistance : params.stage.edgeResistance, dragResistance : params.stage.dragResistance, // dragClickables : true, lockAxis : true, // zIndexBoost : false, snap: { x: function(endValue) { return Math.round(endValue / contextInterface._width) * contextInterface._width; } } }); Here DraggableInstance for MainView (bad perf for vertical scroll) mainView = Draggable.create(mainViewEl, { type : "y", bounds : {minY:0, maxY:-3000}, //SimulateLongScroll throwProps : true, force3D : false, // params.stage.force3D, edgeResistance : params.stage.edgeResistance, dragResistance : params.stage.dragResistance, dragClickables : true, lockAxis : true }); Thanks in advance.
  16. 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
  17. 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!
  18. 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
  19. 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
  20. 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
  21. 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.
  22. 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?
  23. 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"}); }
  24. 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
  25. 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>
