public class PLayer
extends PNode

PLayer is a node that can be viewed directly by multiple camera nodes. Generally child nodes are added to a layer to give the viewing cameras something to look at.

A single layer node may be viewed through multiple cameras with each camera using its own view transform. This means that any node (since layers can have children) may be visible through multiple cameras at the same time.

Field Detail

PROPERTY_CAMERAS

public static final java.lang.String PROPERTY_CAMERAS
The property name that identifies a change in the set of this layer's cameras (see getCamera, getCameraCount, getCamerasReference). In any property change event the new value will be a reference to the list of cameras, but old value will always be null.

Constructor Detail

PLayer

public PLayer()
Method Detail

getCamerasReference

public java.util.List getCamerasReference()
Get the list of cameras viewing this layer.


getCameraCount

public int getCameraCount()
Get the number of cameras viewing this layer.


getCamera

public PCamera getCamera(int index)
Get the camera in this layer's camera list at the specified index.


addCamera

public void addCamera(PCamera camera)
Add a camera to this layer's camera list. This method it called automatically when a layer is added to a camera.


addCamera

public void addCamera(int index,
                      PCamera camera)
Add a camera to this layer's camera list at the specified index. This method it called automatically when a layer is added to a camera.


removeCamera

public PCamera removeCamera(PCamera camera)
Remove the camera from this layer's camera list.


removeCamera

public PCamera removeCamera(int index)
Remove the camera at the given index from this layer's camera list.


repaintFrom

public void repaintFrom(PBounds localBounds,
                        PNode childOrThis)
Override repaints and forward them to the cameras that are viewing this layer.

Overrides:
repaintFrom in class PNode
Parameters:
localBounds - the bounds to repaint
childOrThis - if childOrThis does not equal this then this nodes transform will be applied to the localBounds param

notifyCameras

protected void notifyCameras(PBounds parentBounds)
