Javis get_position doesn't work

Fantastic! i read carefully JCircle.jl and tried to do the same thing with my anonymous function.
the solution is this:

Object(1:nframes,(args...;center =Point(10,30) -> begin
    obj_coordinate = center

    radius = 5
    ....

return obj_coordinate
                                              end ))

should i make your comment as the solution or mine? i m still learning on how to help the comunity
