elements(at:)
Returns all objects whose corresponding locations overlap the specified point.
Declaration
func elements(at point: vector_float2) -> [ElementType]Parameters
- point:
The point in 2D space to search.
Return Value
An array of all matching elements, or an empty array if no objects are found.
Discussion
You specify the point or region corresponding to an object when you add it to the tree with the add(_:at:) or add(_:in:) method. This method follows the same path down the tree as the two addElement methods, but instead of adding a new object to the tree, returns the list of all objects stored in the tree node corresponding to the specified point.
