Sandy's Forum _ AS2 1.x versions _ dynamic line3D constructor

Posted by: 3wme Mar 31 2007, 01:53 PM

I have an array of vectors, and want to create a line joining them. Is there a way of looping through the array in a way that I could put them into the line3d constructor. So...

myLine = new Line3D(points_array[0],points_array[1],points_array[2]...etc), without my knowing the length of the array beforehand?

I could create a group of lines joining each pair of points, but that seems a bit excessive?

any ideas?

cheers

fixed, changed the constructor to accept an array of vectors:

CODE

    public function Line3D ( deb:Vector, fin:Vector )
    {
        super ();
        if( arguments.length < 2 )
        {
            trace('Line3D::Number of arguments too low');
        }
        else
        {
            for( var i:Number = 0; i < arguments.length; i++ )
            {
                if(arguments[i] instanceof Array){
                    for( var i2:Number=0;i2<arguments[i].length;i2++){
                        aPoints.push ( new Vertex( arguments[i][i2].x, - arguments[i][i2].y, arguments[i][i2].z ) );
                    }
                }
                else{
                    aPoints.push ( new Vertex( arguments[i].x, - arguments[i].y, arguments[i].z ) );
                }
            }
            generate ();
        }
    }
