I was wondering how to have collision detection between two differente duplicated movie clips. For example, a duplicated bullet hits a duplicated bird, how do I make it so that it detects collision when the duplicated bullet(bullet+x) hits the duplicated bird(bird+x)?

I’m quite new to programming in flash, but I know the basics.

Thanks,
