JavaFX | AmbientLight Class

AmbientLight class is a part of JavaFX. This class defines an Ambient light object. AmbientLight class creates a light source that seems to come from all direction.

The constructor of the class are:

1. AmbientLight(): Creates a ambient light source with default white color
2. AmbientLight(Color c): Creates a ambient light source with specified color

The following methods are inherited from LightBase :

Methods	Explanation
getColor()	returns the color of the light
isLightOn()	returns whether the light is on or not
setColor(Color value)	sets the color of the light
setLightOn(boolean value)	Sets the value of the property lightOn.

Below programs will illustrate the use of the AmbientLight class:

1. Java program to create a ambient light of default color: This program creates a Sphere indicated by the name sphere(radius is passed as arguments). A AmbientLight is created named ambient_light of default white color. A Button named button will be created which will be used to turn the ambient light on or off. The Sphere will be created inside a scene, which in turn will be hosted inside a stage. The function setTitle() is used to provide title to the stage. Then a Group is created, and the sphere, button and ambient light is attached.The group is attached to the scene. Finally, the show() method is called to display the final results.

       // launch the application
       public void start(Stage stage)
       {
   
           // set title for the stage
           stage.setTitle("creating ambient_light");
   
           // create a sphere
           Sphere sphere = new Sphere(80.0f);
   
           // create a ambient light
           AmbientLight ambient_light = new AmbientLight();
   
           // create a button
           Button button = new Button("light");
   
           // create a Group
           Group group = new Group(sphere, ambient_light, button);
   
           // translate the sphere to a position
           sphere.setTranslateX(100);
           sphere.setTranslateY(100);
   
           // action event
           EventHandler<ActionEvent> event =
           new EventHandler<ActionEvent>() {
   
               public void handle(ActionEvent e)
               {
                   ambient_light.setLightOn(!ambient_light.isLightOn());
               }
           };
   
           // set on action
           button.setOnAction(event);
   
           // create a scene
           Scene scene = new Scene(group, 500, 300);
   
           // set the scene
           stage.setScene(scene);
   
           stage.show();
       }
   
       // Main Method
       public static void main(String args[])
       {
   
           // launch the application
           launch(args);
       }
   }

   Output:
   

   

2. Java program to create a ambient light of a specified color: This program creates a Sphere indicated by the name sphere(radius is passed as arguments). A AmbientLight is created named ambient_light of a specified color(RED). A Button named button will be created which will be used to turn the ambient light on or off. The Sphere will be created inside a scene, which in turn will be hosted inside a stage. The function setTitle() is used to provide title to the stage. Then a Group is created, and the sphere, button and ambient light is attached.The group is attached to the scene. Finally, the show() method is called to display the final results.
