Some destroyer AI, finally!
On the following shots you see your submarine in the middle. The destroyer hunting you is at the bottom and then there is a freighter to the left which you can ignore for now.
You see a circle around the submarine which is only there for debugging purposes. In the first screen it is yellow which means the destroyer has lost your position:
I switched to flank ahead so the destroyer could detect me. The circle went red which you can see in the second screen:
Then I switched to Schleichfahrt (slow ahead) which reduces the noise level. The estimated submarine position for the destroyer is now not that "clear" anymore, dependent from the distance to the sub. You can see a slight deviation showed by the red (debug) circle:
When going below the thermal layer (yes this is in!) the chances of getting lost by the destroyer increase significant!
Surfaced things are much worse for the submarine of course!
