have a nice day “ClockworkOcean” 
at the end i finished and fired game:) it works and show joint rotation and rotate the eye Pupil.
but it flees away.
final process is to connect the joint(R_eyeController) to Vector parameter in a right way.
maybe we should use another node to get the exact location of the R_eyeController ?
my brain is burned help me to finish this process.
that is the last video :
