Twine Version: 3.1
Story Format: Harlowe
I am trying to add a cursor animation that appears on all of the passages throughout my story. I copied and pasted the code into the edit story JavaScript page and it did not work. I also tried pasting the code directly into the passage and using the tag and it did not work. I am not sure what else to do to make this work. I’d appreciate any help!
Here’s the link to the code
With minimal alterations to the original material, you can use this within the “Edit Story JavaScript” section.
if (typeof sparkles === 'undefined') {
const TINKERBELL =

<script type="text/javascript">
// <![CDATA[
var colour="random"; // in addition to "random" can be set to any valid colour eg "#f0f" or "red"
var sparkles=50;

It ain’t pretty code, but the end result sure looks awesome on Harlowe’s default black background!
