Hi,

Here is my problem:
I have 3 class: Main.as, Class3dEngine.as, Class3dLight.as.
Main () calls the two other class.
Class3dEngine () generates the scene, the camera view and
Class3dLight () generates the lights

I want to insert the light in my scene.
In Class3dLight () I wanted to make a scene.addChild (light) but I can not do it.

Here are my files
Main.as

package 
{
 import flash.display.*;
 import flash.events.Event;
 public class Main extends Sprite 
 {
  
  public function Main():void 
  {
   if (stage) init();
   else addEventListener(Event.ADDED_TO_STAGE, init);
  }
  
  private function init(e:Event = null):void 
  {
   removeEventListener(Event.ADDED_TO_STAGE, init);
   // entry point
   
   //Engine
   var InClass3dEngine : Class3dEngine = new Class3dEngine();
    addChild(InClass3dEngine);
   //Light
   var InClass3dLight : Class3dLight = new Class3dLight();
    addChild(InClass3dLight);
  }
 }
} 

Class3dEngine.as

package  
{
 import flash.display.*;
 import flash.events.*;
 import away3d.library.*;
 import away3d.library.assets.*;
 import away3d.cameras.Camera3D;
 import away3d.containers.Scene3D;
 import away3d.containers.View3D;
 import away3d.controllers.HoverController;
 import away3d.loaders.parsers.*;
 import away3d.debug.*;

 public class Class3dEngine extends Sprite 
 {
  //engine variables
  public var scene:Scene3D;
  public var camera:Camera3D;
  public var view:View3D;
  public var cameraController:HoverController;
  
  public function Class3dEngine() 
  {
   //Base
   Parsers.enableAllBundled();
   
   //Creation d'une nouvelle scene
   scene = new Scene3D();
   
   //Initialisation de la camera
   camera = new Camera3D();
   camera.lens.far = 2100;
   
   //Initialisation de la vue
   view = new View3D();
   view.scene = scene;
   view.camera = camera;
   
   //setup controller to be used on the camera
   cameraController = new HoverController(camera, null, 45, 20, 1000, 10);
   
   //on affiche la vue
   addChild(view);
   
   //Affichage des stats
   addChild(new AwayStats(view));
  }
 }
} 

Class3dLight.as

package  
{
 import flash.display.Sprite;
 import flash.geom.Vector3D;
 import away3d.lights.DirectionalLight;
 import away3d.materials.lightpickers.StaticLightPicker;
 
 public class Class3dLight extends Sprite
 {
  public var light:DirectionalLight;
  public var lightPicker:StaticLightPicker;
  public var direction:Vector3D;
  
  public function Class3dLight() 
  {
   light = new DirectionalLight(-1, -1, 1);
   direction = new Vector3D(-1, -1, 1);
   lightPicker = new StaticLightPicker([light]);
   addChild(light);
  }
 }
} 

Thank you,
Kevin

Hi,

instead of adding the light, you simply apply the light to a material

material.lightPicker = your_lightPicker;

But in case I want to apply a single light source for my whole scene and then all my objects. example: the sun.

The usefulness of the system is able to generate just the lights and you can modify the display by passing parameters.
One class but several results.

I will also apply to principle by creating a class to generate the objects by like this: myclass(nameofmyfile).

I do not know if I am very clear and I am sorry.

Thank you for the tip, gonna make my life easier.

But for what I wanted to do, there is no solution? because I guess I’ll get the same error when I want my mesh insert

meshes are added to the scene like you said:

scene.addChild(mesh);

if you need to add 3d stuff to your class, i advise a setup like this:

import away3d.containers.ObjectContainer3D;
public class Class3dStuff extends ObjectContainer3D
{
...
addChild(mesh);
...
}

later you add the instance of the Class3dStuff to your scene:

var class3dStuff = new Class3dStuff ();
scene.addChild(class3dStuff );

I just changed my code and it’s perfect.
Thank you very much, it’s been a pleasure to see an active forum community.
