Percentage Along A Curve

Hi All,

How would I get the percentage that an object has traveled along a curve?:yes:

I would like 0% to be the start of the curve even though an object can “pre-travel” before it reaches the first point of the open curve.

I would like 100% to be the end point of the curve even though an object can “post-travel” past the end of an open curve.
On a closed curve, the value of 0% and 100% would be the same.

Try follow path contraint or writing a script that interpolates curve point values according to the cubic bezier equation (search wikipedia på bezier curve). You will need to extract four points from two bezier triples in blender and then increase a variable (t) over time (0 < t < 1)…
