Here is an interesting new problem for H.sie:
When the U-boat goes to silent-running, the pumps are turned off and the U-boat should sink very slowly. However, the U-boat in SH3 does not sink at all. This problem is not fixed with any mod, and it cannot be mimicked in any way by the player. Therefore, when the U-boat attacks any convoy, the easy (and unrealistic) procedure in SH3 is to go to silent-running at once. It would be much more interesting for the player if he has to judge when to turn silent-running on and off, in order to avoid detection and also to avoid sinking. (The old 'Aces of the Deep' program had this feature.)
One solution to this problem would be to alter the parameter 'mass' loaded from file NSS_Uboatxy.sim (where 'xy' = 7c, 9c etc). The value loaded from the .sim file is zero in stock SH3 and NYGM (a high value with GWX), and represents 'negative buoyancy'. That is, the *lower* the figure, the more the U-boat will sink. The parameter needs to become negative when silent-running to ensure a slow sinking. Then restore the value to its original value when silent-running is cancelled.
I think H.sie has already discovered the silent-running code routines for his realistic repairs mod, so I hope that this problem would not be too difficult for him.
Stiebler.
