set SplineController position from code

[edwon]

I am simply trying to set the SplineController position (along the spline) from code. I want to be able to control it with a 0-1 value. I thought that this would work, but it doesn't:

splineController.Position = moveValue;

there is no error, it just doesn't do anything. The spline variable is set properly. I've tried changing the move mode and position mode and nothing works, please help
