Zoom and pan

I need to make a map with pan and zoom in as3 . I searched for a long time and haven’t found a tutorial or something. All I have found are a few examples in as 2, like :

I’m a newbie at both as2 and as3 so i can’t understand and convert all the code. Can anyone help me with a tutorial or something?:slight_smile: thanks

I managed to do what I want except one thing.For that i need to know can I change the registration point from timeline.Does anyone know how to do that?
