Animating a Dot along an animated path.
Hello, I have what I think is a pretty simple animation but I’m having difficulties trying to animate it without doing it almost frame by frame.
So I have this animation/frame:
apologies for the very crude drawing, wrist brace. So that red dot is moving from left to right along the black wave line. This black line also continues to move and undulate up and down as a wave, so it is never the same shape.
My current set up is that I have the wave created using a Shape layer (because I need to be able to change the dash-lines/height/stroke look on it, and using a Mask Path + stroke doesn’t really give me that much of an option; unless there’s something I missed), and I animate the path and just alternate between the up and down motion keyframes. Then I basically eyeball and hand-keyframe the movement of the red dot across.
Is there any way that does not require me to hand keyframe each of the moving dot?
Thanks!

Why don’t you just use Text on Path, and use a period character? If you’re not familiar with the feature, here’s some info on it:

I’ve tried to do this method, but because the shape of the wave is also changing, the path that I copy paste into the dot’s position property only works for that instance in time of that specific shape of the wave, and then does not follow the rest of the wave’s movements 🙁

:0! I haven’t considered this at all. I will look into this method when I can. Thank you.
