Hi,
In the download package of above link, you can see how it’s loaded via the demo.
With template built with t3 framework, you can put into the JS folder: root/templates/your_default_template/js/
and put the necessary JS files into this directory (like particles.js / stats.js / app.js)
Then when you want to call these files in modules or other parts, you can use script like this:
<script type="text/javascript" src="<?php echo T3_TEMPLATE_URL ?>/js/particles.js"> </script>
<script type="text/javascript" src="<?php echo T3_TEMPLATE_URL ?>/js/app.js"></script>
<script type="text/javascript" src="<?php echo T3_TEMPLATE_URL ?>/js/stats.js"></script>
