◆ DistanceToFeature()

double com.google.appinventor.components.runtime.MapFeatureBase.DistanceToFeature	(	MapFeature	mapFeature,

Computes the distance between the type% and the given mapFeature. If centroids is true{:.logic.block}, the computation is done between the centroids of the two features. Otherwise, the distance will be computed between the two features based on the closest points. Further, when centroids is false{:.logic.block}, this method will return 0 if the type% intersects or contains the mapFeature. If an error occurs, this method will return -1.

Parameters

mapFeature	The feature to compute the distance to
centroids	A flag to indicate whether the distance should be computed from the centroids of the two features (true) or from the edges of the two features (false).

Returns: The distance in meters between the two features or -1 if there is an error.

Otherwise, the distance is computed from the closest point on the type% to the given point. Further, this method will return 0 if centroids is false{:.logic.block} and the point is in the type%. If an error occurs, -1 will be returned.

Parameters

latitude	The latitude of the point to compute the distance to
longitude	The longitude of the point to compute the distance to
centroid	A flag to indicate whether the distance should be computed from the centroid of the feature (true) or from the edge (false).
