Arcade: Iterate over line features and get endpoint

StefanAngerer — Wed, 02 Nov 2022 10:59:30 GMT

Hi everybody,

I am currently working on a problem related to arc arcade, arc pro. Basically I am trying to create an attribute rule that checks if a created feature intersects with any endpoint of a featureset of polylines. For this to work I created this code:

for(var line in lines){

var endPoint = Geometry(line).paths[-1][-1]

return count(intersects(endPoint, Geometry($feature))) > 0

}

This should return "False" if the created feature is not intersecting one of the line endpoints im trying to iterate over. However all I get is a "unexpected null" error at "var endPoint". Any Ideas how i could solve the problem and get the end points of all the line features im iterating over?

Thanks.

Stefan

// get all intersecting lines var lines = FeaturesetByName($datastore, "TestLines") var i_lines = Intersects(lines $feature) // loop thorugh those lines, return true if any end point intersects $feature for(var line in i_lines) { var end_point = Geometry(line).paths[-1][-1] if(Intersects(end_point, $feature)) { return true } } // no end point intersects $feature return false
