How to do a animating sine outline?

This isn’t exactly what you are asking for, but maybe it can still be useful.
You can create a series of points to represent a sine wave. Start with one circle and convert the origin to add, change the add scalar to sine type and then change the sine rate to linear. Set the desired angle rate and add amplitude to get the circle bobbing. Duplicate and time offset to finish.

I haven’t managed to make an individual outline layer do this without lots of repetitive work to setting up each vertex independently. Maybe someone else has an idea about how to propagate spline vertexes within the containing list.


WOW.this is very closely.thank your so mucn.

Sine spline is fun.
