Hi Zach. There is no relation between the triangle and the square per se. The triangle is just there, for this example, as a visual timeline playhead position indicator.
I will update to code to use Set (as it makes sense).
With regards to Position. I would happily use it, as again - it would make sense, but I don't think I can as I am using keyframes, and I canny find anywhere to place the 'position' parameter for each sub-tween. i.e. Where would the 2 keyframed sub-tween's position parameters go in the below example snippet?
tl.set('#FL0S1_sqr', {keyframes: [
{x: '563', y: '0', duration: 0, delay: 1},
{x: '1126', y: '0', duration: 0, delay: 1},
]}, 0);
Also... I definitely forked my original pen. I have double checked and can see it listed as such on the details page.
Cheers
