Hey RedFox,

Sorry about that, looks like LineSegment being in the primitives package is a bit confusing. We’ll put it in a better place and try to be clearer in future releases.

To do what you want you can do something like this:

var lineSet:SegmentSet = new SegmentSet();
   for(var i:uint; i < 1000; ++i)
   {
    var start:Vector3D = new Vector3D(rand(-500, 500), rand(-500, 500), rand(-500, 500));
    var end:Vector3D = new Vector3D(rand(-500, 500), rand(-500, 500), rand(-500, 500));
    var line:LineSegment = new LineSegment(start, end, 0xFFFFFF * Math.random());
    lineSet.addSegment(line);
   }
   view.scene.addChild(lineSet); 

Which results in this:

I’ve updated SegmentSet.as to have a new method:
public function getSegment(index:uint):Segment

This way you can retrieve a segment by index and alter it.

You will need to use the latest fp11 version in github to be able to use this.

thank you for your reply,and sorry to trouble you so many times. i finded the way to solve the problem.
i stored the lineSegement objects in another Array,when i need to change line’s properties,i get it from line’s Array,and update it,then set it in SegementSet’s updateSegment method,it worked.

Sure, that works, but you can obviate your array given that SegmentSet keeps track of its line segments, and with the method getSegment(index:uint):Segment that I’ve put in, you can now retrieve them.

No difference in your results, just letting you know that you can do it that way.
