Hi Raymond,
The error message indicates that you are using the wrong constructor
when you create your RotationInterpolator.
You must use either
new RotationInterpolator( alpha, target )
or
new RotationInterpolator( alpha, target axisOfRotation )

>To get a smooth animation I was told I need to use RotationINterporlator to
