Cloning Display Object in AS3

Report · Nov 21, 2010

Hello all, I am trying to load a SWF in to an Application, then have that application create X amount of that original SWF. Back in the days of AS2, you call the duplicate function, but no more in AS3.

So, I have been able to do this by creating a new class then create a new object in a loop (works fine) there are 2 ways i've been able to do this:

use getDefinition of the linkage Name
convert DisplayObject to an object then assign the constructor as a class

Both of these create a unique version of the SWF (GREAT!) however, when i use the second method, the mouse and keyboard events don't work, (even though the added and OEF both work on both) and for the life of me i can't figure out why.

If i place a breakpoint at the end of the for loop i see that 'b' has 7 listeners. Anyone have this issue / provide suggestions for solutions?

Thanks!

Interesting observation...

I played with it for awhile and it looks like objects instantiated through constructor and sometimes event classes gotten through applicationDomain.getDefinition loose their InteractiveObject flavor.

If this is intentional - it may make sense for security reasons (I am not sure about it though). Otherwise, let's what can be found on this topic...
