Hey Scott,
I'm not an expert with this, but perhaps I could help a bit...
I see 2 scenarios for what you are wanting to do:
1) For a simple primitive like spheres, cubes, planes, etc, object.material
would return the instance of the IMaterial used for it. This could be a
BitmapMaterial, WireColorMaterial, ColorMaterial, etc... so you could test
to see what type of material it is with an "obj.material is
WireColorMaterial" sort of if, and assign to a variable of the proper kind
after knowing what it is. If you know it is a ColorMaterial, then:
var mat:ColorMaterial = object.material as ColorMaterial;
trace(mat.color);
2) If the object is complex and comes from an external source, you might
have to look into its materialLibrary property instead of the material
property since it is likely to have more than one material assigned to its
faces. In such case, you would have to sweep through the material data
elements in its material library, something like this:
for each(var mdata:MaterialData in obj.materialLibrary)
{
trace(mdata.type);
etc...
}
As always, this is just a suggestion and there might be a better, more
efficient way to do what you need.
Hope it helps!
