Method Details

restartBatch

protected void restartBatch()

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

onNodeAdded

public void onNodeAdded(Group parent,
 StageNode3D node)

Specified by:

onNodeAdded in interface StageSubscriber

onNodeRemoved

public void onNodeRemoved(Group parent,
 StageNode3D node)

Specified by:

onNodeRemoved in interface StageSubscriber

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

drawBackground

public void drawBackground(ColorRGB backgroundColor)

Specified by:

drawBackground in interface StageVisitor

drawLine

public void drawLine(Primitive graphic,
 Line line,
 Transform globalTransform)

Draws a line using libGDX's ShapeBatch. Drawing lines will always trigger a mode switch, as "line mode" and "fill mode" are separate and lines are the only shape without a fill.

Specified by:

drawLine in interface StageVisitor

drawSegmentedLine

public void drawSegmentedLine(Primitive graphic,
 SegmentedLine line,
 Transform globalTransform)

Specified by:

drawSegmentedLine in interface StageVisitor

drawRect

public void drawRect(Primitive graphic,
 Rect rect,
 Transform globalTransform)

Specified by:

drawRect in interface StageVisitor

drawCircle

public void drawCircle(Primitive graphic,
 Circle circle,
 Transform globalTransform)

Specified by:

drawCircle in interface StageVisitor

drawPolygon

public void drawPolygon(Primitive graphic,
 Polygon polygon,
 Transform globalTransform)

Specified by:

drawPolygon in interface StageVisitor

drawSprite

public void drawSprite(Sprite sprite,
 Transform globalTransform)

Specified by:

drawSprite in interface StageVisitor

drawText

public void drawText(Text text,
 Transform globalTransform)

Specified by:

drawText in interface StageVisitor

finalize2D

public void finalize2D(Stage stage)

Description copied from interface: StageVisitor

Called after all 2D nodes on the stage have been visited. This is an optional method, the default implementation is empty.

Specified by:

finalize2D in interface StageVisitor

visitGroup

public void visitGroup(Group group,
 Transform3D globalTransform)

Specified by:

visitGroup in interface StageVisitor

drawMesh

public void drawMesh(Mesh mesh,
 Transform3D globalTransform)

Specified by:

drawMesh in interface StageVisitor

drawLight

public void drawLight(Light light,
 Transform3D globalTransform)

Specified by:

drawLight in interface StageVisitor

finalize3D

public void finalize3D(Stage stage)

Description copied from interface: StageVisitor

Called after all 3D nodes on the stage have been visited, but before the 2D nodes are visited. This allows renders that support both 2D and 3D graphics to switch from rendering 3D graphics to rendering 2D graphics. This is an optional method, the default implementation is empty.

Specified by:

finalize3D in interface StageVisitor

toScreenY

public float toScreenY(float y)

dispose

protected void dispose()
