视差滚动与移动的单词/字母 [英] Parallax scrolling with moving word/letters
本文介绍了视差滚动与移动的单词/字母的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在做一个项目，需要基本上复制网站标题的字母与滚动一起移动的效果（就像这里： https://en.playkot.com/ ，这个单词PLAYKOT）。
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).
你知道如何在滚动，不同方向和不同长度的字母移动时如何实现这种效果？我不确定scrollmagic和/或补间之间的相互作用。
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.
推荐答案
我设法解决了这个问题，看看这里：
使用完整页面视图（最好在我的 CODEPEN 上）正确查看请注意，因为这不是（但可以很容易地变成）响应版本。
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.
