Yeah again i faced a little strange problem that i solved it. In my one of previous post i wrote about using movieclip with plane primitives of papervision and also accessing that movie. Now comes the main discussion of this post that is accessing movieclip from papervision plane.

Lets say i have attached a mouse listener to plane to which moviematerial is mapped. So when i click plane i want to do/manipulate the movieclip that is mapped to plane via moviematerial so code would look something like this:

private function planePressed(event:InteractiveScene3DEvent):void{
var as Movieclip;
// do manipulation or changes on moviemc

the above snippet works, i mean u can access the movieclip on above do the later changes to it if u want.

But lets say there is no listener attached to the plane but later in program cycle i want to modify the movieclip attached to plane like applying blurr filter to it. Then i would do something like this:

var as Movieclip;
//apply blurr filter to mc

Well the above code didn’t work for me. In previous above event handler i traced and it traced plane object, so it seems like ‘.material’ returned MaterialObject3D so i have to first downcast it to MovieMaterial separately and then try to access movie property on it. Here is the error:

So here is how is the stupid solution 😀

var mat=my_papervision_plane.material as MovieMaterial;
if(mat){//just being safe
var as Movieclip;

So that worked. But still i didn’t had to do that inside my event handler when i was accessing via, maybe i am missing something out. Right now i am going through docs of papervision.
