How do i make a shotgun?

i want to make my starship shoot 3 bullets at lets say 10 degrees apart from each other, and then wait like 1 or 2 seconds between shooting again, how could i do this?

also could you maybe explain this in a way that a construct 3 noob like me can understand?

It's simple enough to do: dropbox.com/s/9857nngxve9u0mz/bullet_hell_pattern.capx
