Read the speed of pixel / second
Hello I need the number to be fast value of an object for an expression.
In the curve editor so that it can be displayed without problems, I need only the formulation for this worthy, Represent pay them a tachometer-like a car racing show (offset adjustment factors).If an object is for example a 30 pixel Pro sekunde moves in the current frame, I need the worth 30 in the current frame as an expression formulated for a plane, so to speak text.
I though a few experiences with expressions, But this seemingly simple problem I just fail.
Many thanks for the feedback schonmal.
