I need some help understanding using arrays.
What I'd like to do is using the selected points in a PointSelectionTag.
Add those points positions and divide by the amount of points to get a mid position.
I come as far as the code below, I get the indexes and corresponding positions,but cannot get the grips of using an array to store and calculate them.
Given that the result allready is an array, as it looks, I might be on the wrong track, maybe.....
I -assume- I'll have to use an array for this, if not is there a better way?
var link = op#ID_USERDATA:1; // A object in a linkfield
if(link->IsInstanceOf(Tpointselection) !=FALSE) // If it is a PointSelectionTag run
println("YES"); // It´s a pointselectionTag
// Get the selected points , index and position
var pointsel = link->GetSelection(); // get whats stored in the Tag
var count = link->GetObject()->GetPointCount(); // get the amount of points in the object
for (i=0; i< count; i++)
println(link->GetObject()->GetPoint(i)); // Prints the selected points position(s) as an array
println(i); // print the indexes of the points
println(found); // prints the amount of selected points
Here I need to add all selected points positions and divide by found to get the avarage position

not sure why you want an array for this, but simply use a vector for this.
Just before your for loop set
var p = 0;
and in your loop
p += op->GetPoint(i);
then right after your loop, simply divide the sum by your variable "found".
p /= found;
that´s it. Or did you want to do anything else?

No, this is very much what I'm after, thanks!
I just have to init the positions as vectors as well and it should be fine:)
