i'm haveing a hard time with the hull on two of my ships. it would seam that you have to target the hull to distroy the ship, the health bar of the enemy ship will run out but the ship is still very much alive. in other words if you don't target the hull than it takes a very long time to distroy the ship. i don't know how to change this. i did make the hull radius larger as it was too small, but i have run out of ideas. i'm anxious for any help, thanks.
Check to see if the hull property is set to critical. If it is not then the ship will not explode when the hull system is destroyed.
also check the radius of the hull. it should span the entire size of the ship.
