Hi,
I'm new to Away3D, so don't go crazy if this question was already
here.
I'm building up a site with a couple of triangles rotating in front of
a picture. Everythings works but I'm getting errors when I'm loading
the site. As far as I can judge it there must be a problem with the
render() method in my class.
The projects structure looks like this
-Main
--Background Picture
--Triangles
The first of the five errors tells me this:
TypeError: Error #1009: Der Zugriff auf eine Eigenschaft oder eine
Methode eines null-Objektverweises ist nicht möglich. (means null
object reference)

The class looks like this:
package de.kai_reinhardt
{
import away3d.containers.View3D;
import away3d.core.base.Vertex;
import away3d.loaders.Obj;
import away3d.materials.ColorMaterial;
import away3d.primitives.Triangle;
import flash.display.Sprite;
import flash.events.Event;
import flash.filters.DropShadowFilter;
import gs.TweenLite;
public class LoadingSphere extends Sprite
{
private var view:View3D;
private var refArray:Array;
private var schwarz : ColorMaterial;
public function LoadingSphere(x:int , y:int)
{
refArray = [];
view = new View3D({x:x, y:y});
schwarz = new ColorMaterial(0x000000);
genTriangles();
addChild(view);
// re-render every frame
addEventListener(Event.ENTER_FRAME, update);
}
private function genTriangles () : void {
for (var i : int = 0; i < 20; i++)
{
var tri : Triangle = new Triangle();
tri.a = new Vertex(0,Math.random()*100+100,0);
tri.b = new Vertex(Math.random()*20+20,0,0);
tri.c = new Vertex(Math.random() * -20 - 20, 0,
0);
tri.rotationX = int(Math.random()*360);
tri.rotationY = int(Math.random()*360);
tri.rotationZ = int(Math.random()*360);
tri.bothsides = true;
tri.faceMaterial = schwarz;
view.scene.addChild(tri);
refArray.push(tri);
}
}
private function update(e:Event):void
{
for (var b : int = 0; b < refArray.length; b++)
{
refArray[b].rotationY++;
refArray[b].rotationX++;
}
view.render();
}
}
}
It's a very simple structure, so I'm confused of the errors. Can
someone give me a hint where the things are going wrong?
Thanks
Kai
