`x`	number	The x coordinate of the top-left corner of the Rectangle.
`y`	number	The y coordinate of the top-left corner of the Rectangle.
`width`	number	The width of the Rectangle. Should always be either zero or a positive value.
`height`	number	The height of the Rectangle. Should always be either zero or a positive value.

Members

bottom :number

The sum of the y and height properties. Changing the bottom property of a Rectangle object has no effect on the x, y and width properties, but does change the height property.

Source - geom/Rectangle.js, line 425

bottomLeft :Phaser.Point

The location of the Rectangles bottom left corner as a Point object. Gets or sets the location of the Rectangles bottom left corner as a Point object.

Source - geom/Rectangle.js, line 451

bottomRight :Phaser.Point
