Really cool text effect

Hey yall, I kind of wanted to recreate the effect that this website has on their Header text for their home page https://www.homagames.com/homa-lab Does anyone have any idea how to replicate it? the closest ive come, is just doing a typewriter effect, but with a randomized letter being shown before the intended letter.

you could do something like this

<h1 data-text-animation="IF YOU’RE NOT USING THIS, YOU’RE JUST PLAYING AROUND"></h1>

<h1 data-text-animation="IF YOU’RE NOT USING THIS, YOU’RE JUST PLAYING AROUND"></h1>

const randomInt = (min, max) => Math.floor(min + Math.random() * (max - min + 1));
const randomString = (length) => String.fromCharCode(...Array.from({length}, () => randomInt(32, 126))) 

textAnimation(document.querySelector("[data-text-animation]"));

function textAnimation (textEl, currentIdx = 0){
  const text = textEl.dataset.textAnimation;
  if(currentIdx > text.length) return;
  textEl.innerText = text.slice(0, currentIdx) + randomString(text.length - currentIdx);
  setTimeout(()=> textAnimation(textEl, ++currentIdx), randomInt(5, 50));
}

const randomInt = (min, max) => Math.floor(min + Math.random() * (max - min + 1));
const randomString = (length) => String.fromCharCode(...Array.from({length}, () => randomInt(32, 126))) 

textAnimation(document.querySelector("[data-text-animation]"));

function textAnimation (textEl, currentIdx = 0){
  const text = textEl.dataset.textAnimation;
  if(currentIdx > text.length) return;
  textEl.innerText = text.slice(0, currentIdx) + randomString(text.length - currentIdx);
  setTimeout(()=> textAnimation(textEl, ++currentIdx), randomInt(5, 50));
}

yeah thats kind of what ive done as well, but their animation, the change isnt being done at just the latest index the function is iterating on, its being done at multiple indexes at the same time, and thats what makes it look so cool tbh and also the part that throws me off

then we'll have to dive into the source... will see if i have some time later on

MarkBoots•7mo ago

found this in the source think they are using this lib (although it's not maintained anymore) https://www.npmjs.com/package/@a7sc11u/scramble

npm

@a7sc11u/scramble

I altered it a bit to make it work in vanilla js. https://codepen.io/MarkBoots/pen/rNgjEJZ as backup here the code

Oh my That’s awesome Thank you so much!!!

MarkBoots•7mo ago

no problem

Great work, but one concern I have for this is it would probably be pretty bad for SEO / potentially accessibility especially since it's the h1, as the text isn't available on the page before the JS is loaded. Would it be possible to maybe include the actual, full text in a sr-only class? Something like this:

<h1 data-text-animation="IF YOU'RE NOT USING THIS, YOU'RE JUST PLAYING AROUND">
  <span class="sr-only">
    IF YOU'RE NOT USING THIS, YOU'RE JUST PLAYING AROUND
  </span>
</h1>

<h1 data-text-animation="IF YOU'RE NOT USING THIS, YOU'RE JUST PLAYING AROUND">
  <span class="sr-only">
    IF YOU'RE NOT USING THIS, YOU'RE JUST PLAYING AROUND
  </span>
</h1>

Not sure how that would read on a screenreader though... might read twice 🤔 if it does read twice, maybe we can remove the sr-only element if the full text is loaded?

clevermissfox•7mo ago

Could add aria-hidden to one and sr-only to the other.

vince•7mo ago

true! didn't think about that 👀
