ahaaa, that's your plan, looks like a realism addon
. Sneaking past the brits out of the harbour to have a nice glass of schnapps, ja ?
Well, I think that in stock SH3 this is more than possible and actually feasible.
GWX looking in above water situations (if you have read the manual) is a totally different ballgame. In a nutshell, your U-boat's overall '
lage' is not only subject to your sleepy helmsman, but will differ also on weather conditions. So, above water going through a storm, it will eat away a knot or two on your speed instead of doing the same run on a sunny day. Dunno if this is actually changing in relation to how deep you are. Even in choppy seas, if you're like 5-7 meters underwater, you are motionless. I' m a diver and I have hands on experience with that.
I dunno about underwater behavior of GWX, I should test it and let you know. Are u running GWX ? , then I can't answer your question (yet) for underwater matters.
Do you have an exact screenshot position for your uboat, as well as your initial bearing, or is there a way to import Lat/Long data onto the SH3 map ?
But if you're running by the second, you're LI, better not be deaf!
