[away3d] 3D Simple Line

[colouredfunk]

Hello,

I am trying to create a simple line between several points/objects in
my 3D scene.

The line doesn’t need to have any curves but it would need to be
around 50 pixels wide. The points will be in all different positions
so the line will need to retain it's shape on angles etc...

I’m using the following code that I’ve taken from various examples,
but I get a compile error ([Fault] exception, information=TypeError:
Error #1009: Cannot access a property or method of a null object
reference. (PathUtils.as) when I use my pos Array for the path.

Please can someone help me out.

Many many thanks



var mat:Material = new WireframeMaterial("yellow", {width:20});
var pos:Array = new Array
                        for each (var obj3D:Object3D in room.children)
                        {
                                if (obj3D.name.substr(0,3) == "Box") 
pos.push(obj3D.position);

                        }
var aPath:Path = new Path(pos)

var aPoints:Array = [];
                        aPoints.push(new Vector3D(-100, 0, 0));
                        aPoints.push(new Vector3D(-50, 0, 0));
                        aPoints.push(new Vector3D(-50, -50, 0));


var rotationPoints:Array = new Array();
                        rotationPoints.push(new Vector3D(0, 0, 0));
                        rotationPoints.push(new Vector3D(-20, 0, 0));
                        rotationPoints.push(new Vector3D(20, 0, 0));

var pathextrude:PathExtrusion = new PathExtrusion(aPath, aPoints,
null, rotationPoints, { flip:true, aligntopath:true, coverall:false,
scaling:1, recenter:true, material:mat, subdivision:18 } );
                        scene.addChild(pathextrude);
