C# interectionEvent to boolList

Hello,

its me again.

i am still trying to master the intersectionevents.(Here it is probably more a list issue)

In the example i intersect various lines in a foreach loop.Then i put the boolean values into a list to check:if (boolList.All(x => x == false))

to add them when they dont intersect.

Now my booleanList just shows up 1 value.i checked in the if condition above with a print and i get all values of the intersection event(not just one,like in the booleanList).

Hope the screencapture explanis it better

here also the code:

private void RunScript(int numberLines, int max, int length, ref object A, ref object B)
{
    List<Line> lineList = new List<Line>();

    Line l1 = makeLine(max, length);//making the first line in the list so that it isnt empty
    lineList.Add(l1);

    for (int i = 0; i < numberLines - 1; i++)
    {

      Line ltemp = makeLine(max, length);//making new line

      foreach (Line l in lineList){//cheking for the line interserctoin event with evey other line in the list

        double a;double b;bool ie = Rhino.Geometry.Intersect.Intersection.LineLine(ltemp, l, out a, out b, 0.001, true);

        List<bool> boolList = new List<bool>();//adding values to list of booleans

        boolList.Add(ie);

        if (boolList.All(x => x == false)){//if alls values are false add the line
          Print("not intersected");



        BoolList = boolList;

      }
    }
}

    A = lineList;

}

// <Custom additional code>
//makes random

RangedRandom rand = new RangedRandom();
class RangedRandom : System.Random {

    public RangedRandom(): base(){}
    public RangedRandom(int seed): base(seed){}

    public double NextDouble(double max){
      return NextDouble() * max;
    }

    public double NextDouble(double min, double max){
      return (max - min) * NextDouble() + min;
    }
}

//makes the random lines
public Line makeLine(int max, int length){
    Point3d temPt = new Point3d(rand.Next(0, max), rand.Next(0, max), 0);
    Circle tempC = new Circle(temPt, length);
    Point3d temPt1 = tempC.PointAt(rand.NextDouble(max));
    Line l = new Line(temPt, temPt1);

    return l;
}

// </Custom additional code>

How do I obtain getting the Line just added when it doent intersect.

Thanks in advance!

See Attached!

List<bool> boolList = new List<bool>();

for (int i = 0; i < numberLines - 1; i++)

{

......

boolList.Add(ie);

......

}

hi panda,thanks again!

i tried now to add the ltemp line just when they dont intersevt,but it when i do it the foreach loop i got an error message,think its cause i am changing the listcount, so i tried it in a new for loop,but then the machine freezes so i think i made a infinte loop or something.maybe you an help me in this too?

thanks!

hi,

thanks again,

i think i am explaining myself really bad,sorry for that.

I try to just add the line when it doesnt intersect with any other line in the list.

But now i realized in the current version it wont be possible, because the random everytime a line gets added changed the position of th existing lines.

I try to use it as a base(exercise) to be able to populate without that the geometry clashes.

I hope i did not explained terribly again.

Thanks a lot for your effort.

regards!

also added my las try.

Not sure if a bigger change is necessary?
