[TEC] Tweaking submarine ranges

For instance - if you set "cruise" speed to be 10 knots, and max range at 6500 miles, with a max speed for the sub to be say 15 knots, 10 knots will get you farther than 12, or 8, or any other speed. The farther your speed is from the cruising speed - the less range you will get because your either way your burning fuel faster than your moving.....

The way the game engine does it, you cannot set the range for different speeds, only for the most efficient one.

While I know alot has been made about the lack of multi-engine control, and I agree it would be nice to have, just think of this as something your chief engineer handles. At all ahead slow he might only be running one engine for propulsion, allowing it to do double duty to charge the battery as well, because why burn fuel running engines that are not being utilized? Anyone ever notice you have 4 engines - but the throttle control's are in 1/3 increments? At ahead 1/3 - one engine goes to propulsion - another is fired up to provide a charge.... the only time all 4 engines would be devoted to propulsion alone would be at flank speed (or ahead for home!).

Doing so makes the way the game engine handles fuel and speed algorithms at least... sane. It also limits the way we can modify them. It would be nice if we could define different ranges at different speeds, but that just isnt something that is possible as I understand it.

Hope this helps.

I assume that these modifiations are done in the NSS_submarine.sim for each sub class. What program and where can it be found that will allow me to edit the .sim files.

Tony, I suggest using S3d - which can be found here:

Just open the appropriate .sim file for the boat you want to edit. I haven't looked to see what fields would need to be changed in S3d - been using it for other stuff

The other tool you can use it NvDrifter's great MiniTweaker. It (with tweakfiles) can be found here:

If using the Minitweaker - open the relevant .sim file and under either diesel or electric propulsion (depending on which your wanting to change) - just modify the MilesSurfaced/MilesSubmerged to equal what you want the max range to be, then set knotsSurfaced/knotsSubmerged to be the "most" economical speed - this speed will go the max distance - the miles specified above it. Any other speed will give you less distance.

Dont forget to make backup copies of files before ya edit! Enjoy and good luck!

Thanks for your help. This should keep me busy for a while.

Thanks again,

I'm busy doing a speed/rev chart for all the ships and I've found that they have used simple fomulas for their speed/rev calculations as charts produced from all my timings show the same shape.
The Hiryu carrier's chart is a complete mess (it might be an oversight of the DEVs) so I played with it in Minitweaker to get it like the other carriers and found that I was limited to 'sliding' the Min/Mid/Max points up and down the chart, and was unable to do individual changes.

They might have the same story for the engine speed/fuel consumption.
