[Closed] select filter

Trying to find way in which pickbutton can be filtered to select points or spheres. Have tried this and doesnt seem to work.

fn select_filter o =
(
ClassOf o == Point or Sphere
)

Have also tried breaking two select filter functions. One for Piont and another for sphere and then having a radio button to toggle between selecting either one or other. Doesn’t seem to work either. Any ideas on this one?

on pickPoint_radio changed state do
(

    if state == 1 then 
    (
        PointTracking.pickPoint_1.filter = point_filter 
        PointTracking.pickPoint_2.filter = point_filter 
        PointTracking.pickPoint_3.filter = point_filter 
            
    )

    if state == 2 then 
    (
        PointTracking.pickPoint_1.filter = sphere_filter 
        PointTracking.pickPoint_2.filter = sphere_filter 
        PointTracking.pickPoint_3.filter = sphere_filter 
            
    )


)
