Sorry, I need to rephrase my question … too hard to understand currently.
What I wanted to say:
I have a bar moving from left to right. I now need a dot to follow the bars movement on the x-axis. Therefore I parent the dots x-position the bars x-position. However I now also need the dot to follow the path of the curve while it’s parented to the bar. Essentially the missing data for the dot is the y-position of the curve path at time x of the bar.
As you can see the in the example renders either the dot and bar are out of sync or the dot is not following the path properly … How to fix this?
