intersects (Rectangle.intersects method)

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.

Availability: ActionScript 1.0; Flash Player 8

Parameters

toIntersect:Rectangle - The Rectangle object to compare against this Rectangle object.

Returns

Boolean - If the specified object intersects with this Rectangle object, returns true; otherwise false.

Example

The following example determines whether rectA intersects with rectB or rectC.

import flash.geom.Rectangle;
var rectA:Rectangle = new Rectangle(10, 10, 50, 50);
var rectB:Rectangle = new Rectangle(59, 59, 50, 50);
var rectC:Rectangle = new Rectangle(60, 60, 50, 50);
var rectAIntersectsB:Boolean = rectA.intersects(rectB);
var rectAIntersectsC:Boolean = rectA.intersects(rectC);
trace(rectAIntersectsB); // true
trace(rectAIntersectsC); // false

var firstPixel:Rectangle = new Rectangle(0, 0, 1, 1);
var adjacentPixel:Rectangle = new Rectangle(1, 1, 1, 1);
var pixelsIntersect:Boolean = firstPixel.intersects(adjacentPixel);
trace(pixelsIntersect); // false
