Can I use AS2 with AS3?

Hey everyone, I just started using flash and I’m curious to know. I’m creating a document in AS3 but I’m using a script that uses AS2 . Or should I just use AS2 for the whole project? I’m learning as I go, but it’s a pretty simple XML based quiz for a client.

You can’t mix and match AS2 and AS3 .
You can load external swf that uses AS2 inside the swf that uses AS3 , but not the other way around.
Also, they have limited communication capabilities between them.

Hmmm. Okay. Well should I use AS2 ? I think I have more knowledge with AS2 anyways.

Go with whatever script version your project feels better. But for learning Flash in future I recommend you as3.0.

I have created some stuff with AS3 . I found it a bit more confusing, but I always managed to achieve what I needed. For instance, I found out to be very dificult to fully eliminate an external loaded swf. When I mean eliminate I don’t say just hiding it, I mean killing all related processes and onenterframe events. In AS2 you just have to load a new clip on the same spot!!!
I think AS3 only makes sense when you are going for 3D
