warning this is just a test platform not a nice looking ship:
Something that I noticed was that not all the guns pointed in one specific direction at a particular time when confronted by a single enemy. This was the most guns pointed in the same direction that I saw:
I double check the values and they were all fine. I know that they were properly set because when confronted by multiple enemies the guns fire and move in all directions. All angles where set to 90 degrees.
Why not all the guns can get a lock when confronted by a single enemy?
