public class LightNode
- extends Node
LightNode
defines a scene node that contains and maintains a
light object. A light node contains a single light, and positions the light
based on it's translation vector.
If the contained light is a spot light, the rotation of the node
determines it's direction. It has no concept of location.
If the contained light is a Directional light, the direction is relative
to the LightNodes world translation. If the light node is located at
(0,0,0) the DirectionalLight will have no direction and the Light will be
disabled.

LightNode
public LightNode()
LightNode
public LightNode(java.lang.String name)
- Constructor creates a new
LightState
object. The light
state the node controls is required at construction time.
- Parameters:
name
- the name of the scene element. This is required for
identification and comparision purposes.
setLight
public void setLight(Light light)
setLight
sets the light of this node. If a light was
previously set to the node, it is replaced by this light.
- Parameters:
light
- the light to use for the node.
getLight
public Light getLight()
getLight
returns the light object this node is
controlling.
- Returns:
- the light object of the node.
updateWorldData
public void updateWorldData(float time)
updateWorldData
modifies the light data based on any
change the light node has made.
- Overrides:
updateWorldData
in class Node
- Parameters:
time
- the time between frames.
toString
public java.lang.String toString()
- Description copied from class:
Spatial
- Returns the Spatial's name followed by the class of the spatial
Example: "MyNode (com.jme.scene.Spatial)
- Overrides:
toString
in class Spatial
- Returns:
- Spatial's name followed by the class of the Spatial
