Motionpath based speedometer


#1

I know this should be quite easy, but I cant work out how to make a simple speedometer for an object moving along a motionpath.

I’ve had this working on things before, but now I cant figure it out.

Does anyone know if it would be a simple expression on the animated object or whether this needs to be more complex?

I’ve searched online and found plenty of speedometer scripts that work on world x,y,z, but not for objects moving along curves.

Thanks for any advice.
