    • getDisplayWidth

      public int getDisplayWidth()
      Specified by:
      getDisplayWidth in interface TeaGraphics

    • shouldVisitAllGraphics

      public boolean shouldVisitAllGraphics()
      Description copied from interface: StageVisitor
      Indicates whether this visitor should visit all graphics, or only graphics that are currently visible.
      Specified by:
      shouldVisitAllGraphics in interface StageVisitor
    • visitContainer

      public void visitContainer(Container container)
      Description copied from interface: StageVisitor
      Visits a container. This method does not actually need to draw the container's graphics, since the corresponding drawX methods will be called for all the container's children. This method will be called before the container's children are visited. It can be used to handle logic related to the container itself, for example to process children that were added or removed since the last frame update.
      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.
