Rectangle (flash.geom.Rectangle) 1043
intersection (Rectangle.intersection method)
public intersection(toIntersect:Rectangle) : Rectangle
If the Rectangle object specified in the toIntersect parameter intersects with this Rectangle
object, the
intersection() method returns the area of intersection as a Rectangle object. If
the rectangles do not intersect, this method returns an empty Rectangle object with its
properties set to 0.
Availability: ActionScript 1.0; Flash Player 8
Parameters
toIntersect:flash.geom.Rectangle - The Rectangle object to compare against to see if it
intersects with this Rectangle object.
Returns
flash.geom.Rectangle - A Rectangle object that equals the area of intersection. If the
rectangles do not intersect, this method returns an empty Rectangle object; that is, a rectangle
with its
x, y, width, and height properties set to 0.
Example
The following example determines the area where
rect_1 intersects rect_2.
import flash.geom.Rectangle;
var rect_1:Rectangle = new Rectangle(0, 0, 50, 50);
var rect_2:Rectangle = new Rectangle(25, 25, 100, 100);
var intersectingArea:Rectangle = rect_1.intersection(rect_2);
trace(intersectingArea.toString()); // (x=25, y=25, w=25, h=25)
intersects (Rectangle.intersects method)
public intersects(toIntersect:Rectangle) : Boolean
Determines whether the object specified in the toIntersect parameter intersects with this
Rectangle object. This method checks the
x, y, width, and height properties of the specified
Rectangle object to see if it intersects with this Rectangle object.
