Well, that would work if i wanted to step thru all of the mesh
containers children and apply a material change to all faces in it,
BUT my issue is even before that. I only need to change OR update the
material property of ONE face that you happen to click on. Each Face()
object is inside its own Mesh() and there will be many of those groups
created, AND than those groups of items are inside a class file that
Extends ObjectContainer3D so i guess you have access to
ObjectContainer3D methods. A new instance is created of this class in
the MAIN class file where I add an invent listener to that instance as
below:
For now i just have one Face() inside one Mesh() and that i believe is
inside an ObjectCainter3D which is added to the SCENE in the MAIN
class, which is added to VIEW.
At first, this works perfectly to set the Face material property:
var mesh:Mesh = new Mesh();
mesh.name = "H0";
var hex:Face = new Face();
hex.material = new WireColorMaterial(0xFF0000, {alpha:0.2,
wireColor:0xFFFFFF, thickness:3});
In MAIN class:
private function mouseClick(e:MouseEvent3D):void
{
trace(e.object) //Traces "H0: x:0 y:0 z:0" where "H0" is
the name of the mesh ~ mesh.name="H0"
trace(e.element) //Traces NULL
trace(e.material) //Traces [object WireColorMaterial] So, it
can retrieve what its material property is, i just can't change it
after.
//This does not update/change the Face objects color
e.material = new WireColorMaterial(0xFF0000, {alpha:0.2,
wireColor:0xFFFFFF, thickness:3});
//This does not update/change the Face objects color either
var hex:Mesh = gameGrid.getChildByName(e.object.name) as Mesh;
hex.material = new WireColorMaterial(0x9BE0FD, {alpha:0.3,
wireColor:0xFFFFFF, thickness:3});
//This gives me a NULL reference error
var hex:Face = gameGrid.getChildByName(e.object.name) as Face;
hex.material = new WireColorMaterial(0x9BE0FD, {alpha:0.3,
wireColor:0xFFFFFF, thickness:3});
}
Seems like a simple thing, don't think its a bug If I draw a hex shape
using RegularPolygon or WireRegularPolygon, the above mouse event
method to change the color works just fine, granted in that case i had
to set ownCanvas=true otherwise i couldn't set the ALPHA and was
giving me null reference errors, BUT in the case of a FACE object, its
gotta be something simple i am missing.....Maybe after changing the
Face material, the objects have to be refreshed/rendered or etc again
to show up... but that is just a wild guess..... :) I have looked thru
a lot of away3D class files trying to find the material update method,
but nothing....
