actionscript 3 - How do I copy an instanced MovieClip multiple times programmatically? -

i'm extremely new flash/actionscript, i've done c#, java , c++... anyway, question is:

if have movieclip called bird1, , need following:

dostuff(bird1); dostuff(bird2); dostuff(bird3); 

where bird2 , bird3 exact copies of bird1, new instances....
how can until dostuff(bird30); without having copy 30 times , write out?

thanks in advance..

you should assign class name symbol of bird in library:

1. open library f11
2. select bird movie clip
3. open symbol properties window (right click->properties)
4. select "export as" check box
5. assign class name symbol, instance mybird

now can instantiate class many times want code:

dostuff(new mybird());
