Class ScalingViewport

java.lang.Object

com.badlogic.gdx.utils.viewport.Viewport

com.badlogic.gdx.utils.viewport.ScalingViewport

Direct Known Subclasses:

FillViewport, FitViewport, StretchViewport

public class ScalingViewport
extends Viewport

A viewport that scales the world using Scaling.

Scaling.fit keeps the aspect ratio by scaling the world up to fit the screen, adding black bars (letterboxing) for the remaining space.

Scaling.fill keeps the aspect ratio by scaling the world up to take the whole screen (some of the world may be off screen).

Scaling.stretch does not keep the aspect ratio, the world is scaled to take the whole screen.

Scaling.none keeps the aspect ratio by using a fixed size world (the world may not fill the screen or some of the world may be off screen).

ScalingViewport

public ScalingViewport(Scaling scaling,
               float worldWidth,
               float worldHeight)

Creates a new viewport using a new OrthographicCamera.

ScalingViewport

public ScalingViewport(Scaling scaling,
               float worldWidth,
               float worldHeight,
               Camera camera)

Method Detail

update

public void update(int screenWidth,
          int screenHeight,
          boolean centerCamera)

Description copied from class: Viewport

Configures this viewport's screen bounds using the specified screen size and calls Viewport.apply(boolean). Typically called from ApplicationListener.resize(int, int) or Screen.resize(int, int).

The default implementation only calls Viewport.apply(boolean).

Overrides:

update in class Viewport

getScaling

public Scaling getScaling()

setScaling

public void setScaling(Scaling scaling)
