  1. Hi! If I use multiple times without a variable reference //var myVar = TweenLite.delayedCall(); TweenLite.delayedCall(); If I do not call the .kill(), it will increase my memory? Or the delayedCall() have an onComplete() Event to be able to kill() after the calling.? I use the delayedCall() in a loop multiple times with different parameters... Thanks a lot.
  2. Hi Guys, I stumbled on this post http://bassta.bg/2013/05/smooth-page-scrolling-with-tweenmax/ and implement the script there but not the result i wanted. Here is the script that $(function(){ var $window = $(window); //Window object var scrollTime = 0.3; //Scroll time var scrollDistance = 50; //Distance. Use smaller value for shorter scroll and greater value for longer scroll $window.on("mousewheel DOMMouseScroll", function(event){ event.preventDefault(); var delta = event.originalEvent.wheelDelta/120 || -event.originalEvent.detail/3; var scrollTop = $window.scrollTop(); var finalScroll = scrollTop - parseInt(delta*scrollDistance); TweenMax.to($window, scrollTime, { scrollTo : { y: finalScroll, autoKill:true }, ease: Power1.easeOut, //For more easing functions see http://api.greensock.com/js/com/greensock/easing/package-detail.html autoKill: true, overwrite: 5 }); }); How to achieve something like this smooth page scroll on this page - https://www.shift-capital.com/about? Please help.
  3. Hello, I have a problem with my first ScrollMagic Animation. I would like to fade in the boxes on scrolling down. This works fine except for the first time. When I scroll down for the first time the values like opacity don't "tween", they switch directly from 0 to 1. After that I can scroll up- and down with a working animation. It's like some kind of setting is missing. Do you have an idea what exactly is missing? This is my codepen: Thanks, Becca
  4. I'm trying get the white circle to tween to the center of this green square after it has been dragged and dropped onto it. Can't quite seem to get it going - feels like something I should know at this point.
  5. Hello! I need to Tween a number from 0 to 53,5. Is this possible with GSAP? I-m trying and i'm having problems to count decimal numbers. var obj5 = {value:0}, element5 = document.getElementById("cantidadMujeres"); TweenMax.to(obj5, 1.4, {value:"53,5", ease:Linear.easeNone, onUpdate:function() { element5.innerHTML = obj5.value;}}); This is my code, the problem is that the counting number has like ten or eleven digits when init. And, if i add "roundProps:"value" " the decimal digit dont count. The is some solution to this? Thanks
  6. Problem I'm noticing some very strange behavior when I'm updating a timeline's children tween durations. This is problematic for instances where I need to set the duration of the tween after initialization. e.g. an audio clip needs to download before knowing what the desired duration is. Observations The codepen demonstrates this. I construct 10 tweens at 0.2 duration each to a timeline (2s total). When I update each of the tweens' durations to 0.4, several unexpected things are observed: 1. Parent timeline only goes to 2.2 2. The tweens become "choppy" with overlap. It appears that only the last tween expands the timeline, but an interval of 0.2 is still placed between each tween. How can I correct this after updating the duration? Thanks!
  7. Hi If I have a staggerFrom tween that runs from left to right, is there anyway of having the stagger go from right to left on a series of elements? I don't want to reverse the timeline because the stagger is part of a wider / larger animation and when I use the .reverse() method it obviously reverse the timeline. I've given a simplified example below (Codepen example included). The red box comes in from the top and there is a stagger on the blue boxes that come up from the bottom (going from left to right). Is it possible to stagger the blue boxes so they still come up from the bottom, but stagger from right to left? Many thanks var tl = new TimelineMax({repeat: -1}); tl .from("#box", .8, {y:-60}) .staggerFrom(".box", .8, {y:60}, .15)
  8. Hi all, I am doing an interactive exhibit for my school's graduation showcase. In one of the exhibit, I implemented Tracking.js, which could detect colours using a webcam. The effect I want to apply is that, once the webcam detect a specific color, it will append the empty h1 and p tags conditionally (example: if detect Red, append h1 to Header A and p tag to Text A, if detect Blue, append h1 to Header B and p tag to Text B). I use jQuery's .text() function to edit the empty h1 and p tags once it detects a colour. However, the effect is quite abrupt. Is there anyway to use GSAP to animate it? P.S: In the CodePen, I did not put in Tracking.js as CodePen could not access the webcam. I used the .click function to show the .text() abrupt effect I was referring to.
  9. I have a "simple" question (I think that it doesn't need a codePen sample). We have a variable like this: var tx = "TweenMax.to('#element',2,{textShadow:'10px 10px 10px rgba(255, 255, 255, 0.5)'})"; I take it from an xml file. Can I do something like this? tml.add(tx, s); Where "tml" is a timeline and "s" the time in seconds. With this sintax it doesn't work (no error and nothing happens). Is there some other way to do this? Thank you very much for your patience. Mario
  10. Hello fellow tweeners! Hit a brick wall here even though I feel like I've done the hard part. I've been referring to documentation for hours trying to solve this. I'm trying to fire my page loading counter after it fades in, via the tween that does so. Everything is setup & neatly organised/labeled but I'm just butchering the last part lol. The three parts I'm using are marked with lots of asterisks & notes explaining what I'm trying to do. The load counter needs to be nested inside the "onComplete" callback which is already being fired by my tween (console log works)... just not able to get the countdown in. *sigh* Any help would be massively, massively appreciated. Loving the library & community equally! Cheers, Smallio Sorry for the newbie question <3
  11. How do I get an svg object to go to the position of another one? I have been banging my head against a wall. Trying to get pink to follow draggable green. Any help would be great
  12. I have this tween1 that should should work on click and then reverse in case I scroll back. My tween doesn't work, the click doesnt play and so the reverse doesnt work, so: -on click toggle active which will make the f active will have tween1.reverse() //CLICK EVENT ON SECTION 2, AND WHEN SCROLLING BACK TO SECTION 1 IT SHOULD REVERT ALL var tween1 = new TimelineMax(); tween1.to(".click-element", 0.3, {className: "+=active", x: 500, paused: true }, 0) .to('#section-2', 0.3,{className: "+=darkblue", paused: true }, 0) $(".click-element").on("click", function(e) { $(this).toggleClass('active'); tween1.play(); }); var scene1 = new ScrollMagic.Scene({ triggerElement: "#section-2", offset: 50 }) .on("leave", function() { tween1.reverse(); }) .setClassToggle("body", "darkblue") .addTo(controller);
  13. Basically, every time a tween is called in my timeline, I want to recheck the value to be tweened by. `generateValue` seems to be only called once. When I resize the window every time the tween is called it uses the value it first generated. Help would be very much appreciated! function generateValue() { var value; // if window is smaller than 520px if (Modernizr.mq('(max-width: 520px)')) { value = $window.width(); } else { value = 420; } return value; } TweenMax.to($myElement, .2, [x: generateValue});
  14. Hi, fellow GreenSock (forum) members. I'm stuck with animating an object over path, more like generally how to center say rectangle or any path to move smoothly on a path with autorotating. The Codepen pen is a part from what I would like to do but can't center the green "car" e.g. so that its center (midpoint X and Y or centroid if you wish) would move on the path. This year I have created complex animation of a cube moving along the "infinite" path with calculating shadows per rotation angle - with callback function - yet cannot do this simple animation well. Gray path is a rectangle, red one is nearly completed rounded rectangle with Bezier curves. The latter would be perfect but I cannot script the green rectangle to be centered on path at all times. So in general how to draw, position and/or offset an object so that it will move along the path by its center (centroid)? Having a group with invisible rectangle boundaries and then animating a group along the path? And yes, I have watched the excellent Note: I'm using svg.js for some easy creation of SVG elements. Intention is to script all to have rule base path creation and then animating objects over paths. Sure, the path rounded corners will be redone with arc commands :-).
  15. There seems to be a slight flicker once the animation is finished. This only seems to happen with HTML Videos. I was unable to reproduce the effect with other elements such as divs or imgs. Has anyone come across this issue before?
  16. Hi, I'm trying to make an element tween from off screen and land on a point while scaling down. I currently have the element scaling down and moving position but I don't want it to start scaling down until it gets closer to the red box. Any advice or guidance would be great.

    Shake object in place

    I wonder if there is a way to shake an object in place around its current position. I tried RoughEase and tweening from x,y to x,y with the same value. But the shaking will only be visible when they differ. Is there a simpler way than use an onUpdate callback? Thanks
  18. Hi all, been struggling with this for a long time now. Is there a way to tween a draggable, more specifically a type:"scrollLeft" element's position by clicking a button? Think of a draggable, scrolling left and right carousel - with a button. When the button is clicked the draggable element slides to the right 300px. I know there are methods to enable and disable the dragging, but I don't see a way to target the actual moving element. Even to manually go in and target the draggable item with a tween might work... but I can't seem to even find what moves! Thanks for any help you can offer!
  19. Hey, When animating an unknown number of elements like so: var timeline = new TimelineMax({repeat:-1}), items = document.querySelectorAll('.item'), startDuration = 20; for(var i = 0; i < items.length; i++) { var myDelay = (i * 0.5); animate(items[i], myDelay); } function animate(item, delay) { var a = TweenMax.to(item, startDuration, { rotationZ:'360', ease:Linear.easeNone, repeat:-1 }); timeline.add(a, delay); } What is the best way to modify the duration/speed of an individual tween? Thanks
  20. Hey, there! Is there a way to update the value inside tween when getting the animation reversed? For now I need some kind of fake preload animation, before modal window loads, so I'm using delay parameter with a variable value . But when I'm closing modal window (by clicking on a background layer), animation reversing but considering that delay. Is there a way to change that variable value on reverse?
  21. I'm trying to tween an element that has a relative height and it sits inside a container with relative height using absolute positioning. The desired tween animation is to move the element from the bottom of the container until it reaches the center. I'm also using scrollmagic as this animation should only appear during scroll to this container. I tried a few ways first way: default css of the element is already absolute positioned to center, container { position: relative; } element { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); } get the height of the element and its container. Minus off the element height from the container height. divide result by *two pass this height as a parameter in tween created window resize function and update the heights and also refresh the scenes scene is updated but tween is not. The culpit here is Tween not refreshing the variables on resize. Second way: default css of the element is at the bottom of the container with bottom: 0; position is still absolute used a to tween with top: "50%", yPercent: -50 this doesn't put the element in the center it's not centered and it only moves slightly The culpit here is using bottom: 0; and that breaks the absolute centering. Without bottom zero it works but the element comes in from outside of the container. Is there a workaround to this? Please help. Thanks!
  22. Hi ! I'm starting with TweenMax and got stucked with an issue. I have a menu which each links can start an animation but they can overlap and make the tween bug. I'd like each function to complete before being able to start another one. I've found that I should use onComplete but I don't get what I am suppose to do then. I've made a JSFiddle to demonstrate the issue I have. On .mouseover, the tween start but if I hover too fast on an other link, it bugs. :/
  23. Hi All, Im trying to get 2 tweens to animate at the same time when I mouse in over a link, and to reverse the animation when I mouse out. Each tween is working correctly in isolation, they're just not workingvery well together at the same time. The 2nd time you hover, the 2nd tween just jumps between its start and end points, there is no animation at all. I tried adding the position parameter of "0" to the second tweens but it didn't solve the problem Any help appreciated
  24. Hi Is there any way to make a timeline that is inside a function accessible outside of it? I have a short animation sequence used in different places on a site. I'd like to wrap the timeline in a function, but the problem is I'm also using scroll Magic. Thus the setTween method of scrollMagic needs you to pass the name of the tween in as a parameter. I tried using return with the timeline name (as return myAnimation) at the end of the function, but this didn't work. I've set up a simplified example codepen (link given above and minus the scrollMagic) to make it easier to illustrate any solution. I'm thinking there must be a way to make a timeline accessible outside of a function? Any help would be amazing. Emily.
  25. Hi I have gone through a lot of posts and found that tweento(getlabelafter()) will take me to the next label. But the issue is that it doesn't allow me to skip any tween and jump to the next label. Can you please have a look at the codepen n suggest a way to skip a tween so i do not have to wait for the tween to be over before going on to the next label
