Method Details

init

public void init(SceneContext sceneContext)

Specified by:

init in interface TeaGraphics

getDisplayWidth

public int getDisplayWidth()

Specified by:

getDisplayWidth in interface TeaGraphics

getDisplayHeight

public int getDisplayHeight()

Specified by:

getDisplayHeight in interface TeaGraphics

shouldVisitAllNodes

public boolean shouldVisitAllNodes()

Description copied from interface: StageVisitor

Indicates whether this visitor should visit all graphics, or only graphics that are currently visible.

Specified by:

shouldVisitAllNodes in interface StageVisitor

visitContainer

public void visitContainer(Container container,
 Transform globalTransform)

Specified by:

visitContainer in interface StageVisitor

prepareStage

public void prepareStage(Stage stage)

Description copied from interface: StageVisitor

Prepares visiting the stage. This method is called before any of the stage's graphics are visited. It can be used to add initialization logic that should be performed before any graphics can be drawn.

Specified by:

prepareStage in interface StageVisitor
