Working With Rectangles

Creating Rectangles

//
var myRectangle:Rectangle = new Rectangle(0,0,10,10);
// Argument Structure (x,y,width,height)

Argument list 1. x, the x Position of the rectangle 2. y, the y Position 3. width the width of the rectangle 4. height the height of the rectangle

Note that just like points, rectangle x and y positions aren't really relative to any containers, so it only really makes sense to compare rectangles to each other in the same context.

Updating Rectangles

Rectangle positions can be updated with init() like so:

myRectangle.init(40,-7, 100,293);

you can also update stats like so

myRectangle.x = 40;
myRectangle.y = -7;
myRectangle.width = 100;
myRectangle.height = 293;

Checking for overlap

Single Point

Using a Point

var myRectangle1 = new Rectangle(40,-7, 100,293);
var myPoint = new Point(145, 300);
if (myRectangle.containsPoint(myPoint)) {
	Engine.log("myRectangle1 contains myPoint!");
}

Using raw coordinates

var myRectangle1 = new Rectangle(40,-7, 100,293);
if (myRectangle.contains(145, 300)) {
	Engine.log("myRectangle1 contains (145,300)!");
}

Between Rectangles

Complete Overlap

var myRectangle1 = new Rectangle(40,-7, 100,293);
var myRectangle2 = new Rectangle(10,-7, 70,300);

if (myRectangle1.containsRect(myRectangle2)) {
	Engine.log("myRectangle1 contains myRectangle2!");
}

Partial Overlap

var myRectangle1 = new Rectangle(40,-7, 100,293);
var myRectangle2 = new Rectangle(10,-7, 70,300);

if (myRectangle1.intersects(myRectangle2)) {
	Engine.log("myRectangle1 and myRectangle2 overlap!");
}
