  • A color selector script sends an on color on a TRUE input, and an off color on a FALSE input

    field    SFColor offColor 0.0 0.0 0.0
    eventIn  SFBool  set_selection
    eventOut SFColor color_changed
    url "vrmlscript:
        function set_selection( b, ts ) {
            if ( b == TRUE )
                color_changed = onColor;
            else
                color_changed = offColor;
        }"
