Accessing stage inside a custom Away3D class. Software: Away3D 3.x

Pradyumn, Newbie Posted: 03 October 2012 05:41 AM Total Posts: 3 We are working on a game in a team. I have to make a class for 3D, so that game developers can use my Away3D functionality, but they don’t have to bother about the 3D world, they’ll simply pass the X and Y positions of an object— var tile:CustomClass3D_Tile = new CustomClass3D_Tile(400, 300); and they are expected to do nothing more than this, they are not even supposed to addChild the view, I have to do this is my custom 3D class. I’m having difficulty in accessing stage of the Main class inside the custom class, so that I can addChild the objects inside the custom class.
loth, Sr. Member Posted: 03 October 2012 08:17 AM Total Posts: 236 [ # 1 ] hum not clear ? why you wan’t access stage in flash you can use Vector3D(x,y,z); and the “stage” of away3d is the view view.scene = ... view.camera = ... you only have to creat a function to place your object but i don’t understand the probleme
kochumvk, Newbie Posted: 08 October 2012 05:21 AM Total Posts: 17 [ # 2 ] If you are trying to add a 3D object (ObjectContainer3D or mesh) u can add it to your scene var: `private var sphere:Mesh; private var scene = new Scene3D(); scene.addChild(sphere);` If you are trying to add a 2D object (a sprite or movieclip) You can access stage using a proxy for stage (I does that way, using pure mvc)
Alex-Crafter, Newbie Posted: 08 October 2012 07:55 AM Total Posts: 28 [ # 3 ] If you use only 1 3dstage, you can easily do this by assigning your scene to a global variable: //create a global variable outside, like var s:Object={} //then use something like this when initiating your scene var obj:Object={}; var scene:Scene3D = new Scene3D(); var camera:Camera3D = new Camera3D(); var view:View3D = new View3D(); view.antiAlias = 4; view.scene = scene; view.camera = camera; obj.scene=scene; obj.camera=camera; obj.view=view; s.core3d=obj; //you can acess your 3d scene, view and camera quickly with s.core3d.scene s.core3d.camera s.core3d.view But maybe this is too procedural programming for your likes..

Application entry class. 2. Defines stage in Variables.stage (via public static var stage;) so it becomes a singleton and can be called any time you need it. But I only put it there for quick fix purposes when stage has been lost. But my typical flow would be: 1. Entry class extends sprite 2. Application class extends sprite (The spine of the application) 3. Away3DScene class extends sprite In each only assemble when added to stage listener is fired thus ensuring you have access to the stage in each of the classes. EG: Application.as class Application { private var away3DScene:Away3DScene; public function Application() { this.addEventListener(Event.ADDED_TO_STAGE,init); } public function init():void { this.removeEventListener(Event.ADDED_TO_STAGE,init); away3DScene = Away3DScene.getInstance(); // Singleton pattern addChild(away3DScene); // As this class has access to the stage so will this one ensuring it has been added to the stage // Build a mesh code away3DScene.scene.addChild(MyMesh); } Also Instantiating Away3D as a singleton view allows you to call the view from anywhere at any time via: `var away3DScene:Away3DScene; away3DScene = Away3DScene.getInstance();` So even access to the stage is not really necessary. But if you did need it, and you defined it as a static variable in Variables.as you would be able to simply use. `Variables.stage.stageWidth; //etc Just make sure it's defined` Anywere in your application with no problems. But there are many ways….
