问题
I'm doing a project where it's required to basically replicate the effect where the letters of the site title move along with scrolling (exactly like here: https://en.playkot.com/, this word PLAYKOT).
Do you have any idea how can I achieve that effect when letters move during scrolling, in different directions and different lengths? I'm not sure about the interplays between scrollmagic and/or tweens.
回答1:
I managed to solve the problem, have a look here: Use Full page view (preferably on my CODEPEN) to properly see the effect please, as this is not (but can be easily turned into) responsive version.
jQuery(document).ready(function( $ ) {
var $main = $("#header");
var $header_container = $(".header-container");
var $image = $(".h-image");
var $parallax_word = $(".parallax-word");
var $pw_item = $(".pw-item");
var winH = $(window).height();
var controller = new ScrollMagic.Controller();
var scene1p = new ScrollMagic.Scene({
duration: winH
});
var tween1 = new TimelineMax();
tween1.to($main, 1, {
y: -winH / 4,
ease: Linear.easeNone
});
scene1p.setTween(tween1);
controller.addScene(scene1p);
var scene2p = new ScrollMagic.Scene({
duration: winH
});
var tween2 = new TimelineMax();
tween2.to($image, 1, {
opacity: 0.65,
ease: Linear.easeNone
});
scene2p.setTween(tween2);
controller.addScene(scene2p);
$pw_item.each(function(index, element) {
var $symbol = $(this);
var shiftH = $symbol.data("shift");
var tweenI = new TimelineMax();
tweenI.fromTo($symbol, 1, {
y: shiftH * winH / 2
}, {
y: 0
});
var scenep = new ScrollMagic.Scene({
duration: .7 * $main.height()
});
scenep.setTween(tweenI);
controller.addScene(scenep);
});
var scene4p = new ScrollMagic.Scene({
duration: winH
});
var tween4 = new TimelineMax();
tween4.to($parallax_word, 1, {
y: -winH / 5,
ease: Linear.easeNone
});
scene4p.setTween(tween4);
controller.addScene(scene4p);
});

Thanks everyone for interest! :-) I hope it'll help someone. PS: This snippet is part of a bigger project, so there might be some unused parts, sorry for that, but the idea should be quite obvious.
