Jess.Park Posted March 7, 2021 Share Posted March 7, 2021 Hi. I need help with ScrollTrigger + Timeline. I'm totally lost : - ( I have several div.screens that each styles are set by screensData array. What I want to do is below. <when trigger is pinned by ScrollTrigger> 1. animate .bg backgroundColor from 'transparent' to 'black' 2. wait for 0.2s 3. animate each .screens opacity from 0 to'screensData[i].opacity', scale from'screensData[i].scale-=0.2' to'screensData[i].scale' <when trigger is unpinned by ScrollTrigger> - basically reverse the above 1. animate each .screens opacity from'screensData[i].opacity'to 0, scale from 'screensData[i].scale'to 'screensData[i].scale-=0.2' 2. wait for 0.2s 3. animate .bg backgroundColor from 'black' to 'transparent' I thought it was going to be simple, but somehow it's not. Main problems are, A ) screens.forEach animation isn't firing at all. What am I doing wrong? B ) I'm not sure how to convert 'stagger: 0.15 * dir' in forEach function. (stagger in order when scrolled down, stagger in reversed order when scrolled up) C ) Is there a better way to do this with less lines? something like <when trigger is pinned, play timelineA / when unpinned, play timelineA.reverse(0)> See the Pen jOVvXxp by impetusjj (@impetusjj) on CodePen Link to comment Share on other sites More sharing options...
ZachSaucier Posted March 8, 2021 Share Posted March 8, 2021 Hey Jess. You're making some of the most common GSAP mistakes so I recommend fixing those. Your setup is a bit confusing to me though. If all that you're doing is playing or reversing an animation why do you need to create a new animation each time? One of the tips about animating efficiently (another great article to read) is to use control methods to control animations. Link to comment Share on other sites More sharing options...
