Hi Zach,
That is amazing, thank you so much.
Your change makes sense (and is easier than my attempts!), apart from the -90 deg autoRotate part - I don't understand how they are all set to the same -90deg, all start 'facing down', but have different starting orientations (ie the path they each follow).
Changing this new code, to try and see how it works, again partly makes sense (all triangles being the same place, no problem), but changing the value of -90 doesn't make this clearer to me!
Any other explanation as to how this works, or how you 'fixed' my problem, would be really appreciated and useful.
(The triangles starting in the same spot is fine - I'll either move them off screen / fade them in at some point along the timeline).
Thank you again
Jake.
