It's kind of like what I said. You're at the point now where you need
to take a step back and look at the big picture before you can move
forward and make things more interesting.
If I were you, my end goal would be to have a design that lets me
write a bit of code that looks like this:
if (spacePressed) {
bullets.add(new Bullet(turret.x, turret.y, turrent.rotation));
}
It all comes back to the modeling that I'm talking about. Put the
bullet behavior in a Bullet class, and update all Bullet instances
from your main class. Bullets are easy, they travel in a direction at
a speed from a given point. Using code like this, you can have many
bullets in-play easily :)
