little details

I noticed some neat little details:

1. periscope. I was wondering why my attack scope was always coming up pointing towards the stern, but it turns out the scope will rise depending on where you approach it from in the 3d world. If you go around the attack scope and click on it when you are facing the bow, it will rise facing the bow.

2. sonar. I don't know if this was in sh3/4, but the effectiveness of sonar is matched by your speed. The faster or slower you go, the more the background noise increases or decreases, affecting your ability to hear contacts. The sound you hear is also affected by the aspect of the target. A warship coming towards you, which has its screws masked by the hull of the ship sounds different from a warship moving away from you. I spent sometime at the sonar station trying to get past an escort screen, and it is amazing how much info you can pick up from sound alone if you pay attention.
