Papervision Event Listener Idea

Admin — Thu, 03 Dec 2009 10:12:11 +0000

The problem:
While working on a Papervision3D Flash Project I had a problem where a back button that sits above the 3d canvas and acts as a main navigational item was required to change Events according to where the site was in 3d space at the time.

The solution:
Everytime I’m about to add a new EventListener to the back button movieclip I call the function “delBB()” and then add my event listener using addBB(with the event here).

It seems to work correctly and is a faster way of working.

var currentBackListener = null;

function addBB(whatever) {

back_mc.addEventListener(MouseEvent.CLICK,whatever);

currentBackListener = whatever;

}

function delBB() {

if (currentBackListener!=null) back_mc.removeEventListener(MouseEvent.CLICK,currentBackListener);

currentBackListener = null;

}

Usage:

delBB();

addBB(CLOSE_OBJECT_CLICK_MC);

Papervision error 1046

Error: “1046: Type was not found or was not a compile-time constant: InteractiveScene3DEvent.”

I got this this morning when I opened up a project I have been working on. I was using the Flash IDE to compile and FlashDevelop to code in as I am not the biggest fan of the Flash IDE for coding in….. Who is? Right?

Anyways… I tried to publish my swf and I got loads of errors like the one above. So after looking into what was going on I discovered that half of my papervision classes were missing! How the heck that happened I have no idea, as I store them per project basis and not as one standard import.

So check to make sure that you are able to access the papervision classes from your FLA source file.

If you are not sure how to do this then take a look at, File->Publish Settings->Flash->Settings-> and make sure that the Source Path list box is including the correct class directories.
