Propulsion (WIP preview)

Description
Make the UBOAT U-boat run like a U-boat

More info in this thread

On fuel consumption
The fuel usage is now scaled by the geographic position as well as the heading. If you're further North, you draw less fuel while heading East or West. This might sound weird at first, but this system ensures, that after travelling great distances, the remaining fuel in your bunkers will be the correct amount.

The courses plotted follow a rhumb line. If you draw a course along a great circle, the travel distance will be reduced accordingly.

Thanks! I also created additional thread you would like to see

There is some idea how to calculate consumption.

I used an incorrect regression, now I've made the current graph intersect at 0
ПРИЧИНА ТРЯСКИ? 25 Aug @ 10:44am 
DECAFBAD hello again. For testing purposes I commented out some things in the mod files and the power consumption became normal.
It was before: https://ibb.co/ZpLKrVBC
I commented this: https://ibb.co/7xY5Svsq and energy consumption became as expected https://ibb.co/NnCLmpCG
I have found that the power draw (147 Amps) sometimes disappears and reappears when the boat goes through large waves or just after the submarine surfaces.

That's not my mod
There were no auxiliary generators on Type VII boats. That was mostly an American thing.
Points 2 and 3 are not relevant to your mod. I checked again.
DECAFBAD, sorry to bother you, but I found a couple of bugs in this mod:
1) https://gtm.steamproxy.vip/app/494840/discussions/0/595157852294007177/
without mod https://ibb.co/rGfhVhv3
2) Cheat with "Stop & Recharge Batteries" https://ibb.co/TxD0pQY3
3) The auxiliary generator consumes a lot of fuel https://ibb.co/RGCpMSP4 Half a minute and you will lose as much fuel as if you were driving "Dead Slow Ahead" for an hour.

@DECAFBAD Understood.

In UBOAT, drag is around 1000 times greater than in real life. There's a reason for this that I won't go into.
I tried for weeks to modify the way drag was calculated and every method failed. As I found out, this is because it isn't even exposed to the scripting engine, and instead it is calculated in the native memory space of UBOAT.
Even though this is only part of the whole equation, even this residual drag is greater than what the actual value should be. So in the end, I don't believe that it is practical to have a dynamic model of the propulsion system in a mod, there are just too many obstacles.

Reducing the thrust force makes the boat slower, but the speed becomes very unstable due to the immense drag. This crippled gameplay too much, so I've opted to remove it to make this mod have the other beneficial effects.

Not to be a dumb dumb here, but does "Historical surface and submerged speeds for the Type VII" being crossed out mean that this mod no longer add's this feature, or that it's broken in the current release?
