Viewport

open class Viewport(var x: Int, var y: Int, var width: Int, var height: Int)

Rectangular region in a two-dimensional coordinate system expressed as an origin and dimensions extending from the origin.

Constructors

constructor(x: Int, y: Int, width: Int, height: Int)

constructor()

Constructs an empty viewport width X, Y, width and height all zero.

constructor(viewport: Viewport)

Constructs a viewport with the origin and dimensions of a specified viewport.

Properties

var height: Int

The viewport's height.

val isEmpty: Boolean

Indicates whether this viewport is empty. A viewport is empty when either its width or its height are zero (or negative).

The viewport's width.

var x: Int

The X component of the viewport's origin.

var y: Int

The Y component of the viewport's origin.

Functions

fun contains(point: Vec2): Boolean

fun contains(x: Number, y: Number): Boolean

Indicates whether this viewport contains a specified point. An empty viewport never contains a point.

fun copy(viewport: Viewport): Viewport

Sets this viewport to the origin and dimensions of a specified viewport.

open operator override fun equals(other: Any?): Boolean

open override fun hashCode(): Int

fun intersect(viewport: Viewport): Boolean

fun intersect(x: Int, y: Int, width: Int, height: Int): Boolean

Computes the intersection of this viewport and a specified viewport, storing the result in this viewport and returning whether the viewport intersects. Two viewport intersect when both overlap by a non-zero amount. An empty viewport never intersects another viewport.
When there is no intersection, this returns false and leaves this viewport unchanged. To test for intersection without modifying this viewport, use intersects.

fun intersects(viewport: Viewport): Boolean

fun intersects(x: Int, y: Int, width: Int, height: Int): Boolean

Indicates whether this viewport intersects a specified viewport. Two viewport intersect when both overlap by a non-zero amount. An empty viewport never intersects another viewport.

fun set(x: Int, y: Int, width: Int, height: Int): Viewport

Sets this viewport to the specified origin and dimensions.

fun setEmpty(): Viewport

Sets this viewport to an empty viewport.
