In my Final year project.
There is a bit where I need to do a robotic arm.
And when ever an instruction is read and a value is given.
I want to move the arm at a animated style.
I've try to used Behvior class at first and used WakeuponElapsedtime as the
basic way to move object.
To get a smooth animation I was told I need to use RotationINterporlator to
so. But, I can treat it like Behavior class and extends to write a different
class. It would not compile and gave me an errror saying that
RotationInterporlator is design not to be a public class and not to be used
out side the package.
If I try to write out the object in the create Scence Graph method, than I
can do wakeupcriteria check.
Please help if there is other solution to this problem.
yours sincerely
Raymond Lau
