Indeed, everyone has a different take. What is very interesting is with that change in the Sim.cfg, the Hydrophones act as super hydrophones, as if they can see you underwater. That is definitley one way (the only so far I have seen) to get their attention to come over and attack you agressively.
After several hours of playing, I have found the sensitivity settings to change quite easily for the 7 Active Sonars for the DD if you care to play with them, and if TT wants to place them into his tool.
The passive sonar (hydrophones) I have studied the format and am getting closer to solving it. For what it is worth.
Here is the basic data on the Active sonar. It is not all inclusive, just the highlights.
The sensitivity setting number follows just the same format as the other values in the file.
Sensitivity_XXXX a blank space then the hex value in IEEE format.
This is for the Active Sonars only. Bow angle +- 90 degrees left right in the horizontal plane.
The Elevation is the verticle angle to mimick the narrow search light or the late war Sword type sonars. 90 is 'horizontal' . Thus 90-100 would be sea level down 10 degree dip into water (if it even works in game).
Active...range...Elevation...Sensitivity...hex value
123A ...1200m....90-100...0.039999....0A D7 23 30
128A ...1500m....90-100...0.050000....CD CC 4C 3D
144A....2000m....90-130...0.050000....CD CC 4C 3D
147A....2200m....90-155...0.070000....29 5C 8F 3D
QCeA...1300m....90-100...0.050000....CD CC 4C 3D
QClA....1700m....90-100....0.050000...CD CC 4C 3D
QGAA...2000m....90-100...0.059999....8F C2 75 3D
This info is for people who wish to try to tweak stuff some more.
It is a oddity the later war passive sonar used in mission U-505 is the QClP. The numbers maybe mixed up and causes the later war active or passive sonar not to reference anything (making it Uber).
The "1" and the "l" look the exact same in the font in the code, but it gets referenced different in the DD SNS file and the hex code. Maybe that was a small buglet. I am not sure. the "1" instead of being a '11' in hex is a "l" which is 6A in hex.. This would give the late war Everats and Buckley (maybe more) super sonar effect. Maybe.
The hydrophone format indeed is strange, but I can diagram it, and make one behave like the others. I still have not been able to make it super high sensitivity as I want, but getting closer to it..
I only wish to be able to let people change the values to their own playing style. Without that discovery of the Sim.cfg and Hydrophone trick none of this would be possible.
Thanks Hemisent, it is good to be back. I am more enthusiastic to keep trying to mod things since CB and all have made that discovery to waken up those boring DD.
In the end, that maybe is all that can be done, plus tweak the Active sonars to get a good balance. You can also change the ranges too.
Alot of possibilities. Alot of playing styles. I also prefer agressive DD even though it may not be realistic.
