My newest and best version yet "U-571 Type VIIC 'Greywolf'" is now released. Link in the description above.

Power on reactor, bring right side needle up first, then bring up left needle. Try to keep Right side needle in the green, Left side needle in the orange then switch on automatic control. It should take care of itself after that.

You need at least 2 fuel rods in the reactor to get full reactor output. The AI likes to remove them.

Greatings,thanks for upload this ship,I don't konw how to set the reactor always low power or over heatCan U help me plz?

I believe I've finally solved the issue. May take some time to implement and test. 'Greywolf' will be released as soon as the fix is implemented.

I discovered I have to fix my dynamic power regulators.. tried to make them more efficient and instead introduced more dynamic power demand.

If the Mk2's wiring baffles you, Greywolf's is really gonna hurt your brain haha ;)

lol Thanks I guess :) Currently debugging some of the Greywolf's electrical now.. every time I try to make something work better I break something else haha

Already fixed a few issues I discovered during actual game testing (rather than in the editor). Once I get these last few issues worked out it will be up on the workshop.

Wow. You did that fast lol. U-2540 took me like a month for the first release and a couple more months before it became what it is now. I'm still a little baffled when I look at your Mk2 wiring so I think I'll cede you're just better at electronics than me lol.

I've still got to write up a full list of features, but a few of the features are:

- Fully automated and regulated electrical system, with manual override.
- Fully automated battery charging system, with manual override.
- Semi-automated reactor, with auto shutdown if alarm on for more than 8 seconds (gives the auto control time to regulate).
- Silent running with blue lighting, reactor locked off, and switch to shuttle engines (got the engine switch idea from U-2540).
- 4-way switch on attack periscope (spotlight, aft torpedo, fwd torpedo, AA gun).
- Door lock on forward storage compartment to use as makeshift brig.
- Auto sealing Bulkhead doors in event of breach.
- Breach/Flood alarm system in control room.
- Lots of switches to toggle things.
- Dual Ammo Deck guns (another idea from U-2540).
- One other surprise xD

Yeah, its my best so far for sure. I've gotten a lot better at using the editor as well as the wiring. I really wanted to get the aesthetic down, even get that cramped feeling, while still being functional in game. This time I did the build differently. I started with the dimensions/looks, then made everything fit. Its about as close to the real thing as I can get within Barotrauma.

'Greywolf' also has the largest and most complicated set of features of any of my subs. I'd guess there's over 1000 wires running through it, so soooo many components.

I absolutely love that you're building closer to the original VIIC design. Looks really sharp and exciting.

Looking real good. Can't wait.

As promised, added a couple of pics of the new 'Greywolf'. Should be releasing it tomorrow. It will be a separate Workshop file, but I will link it in this files Description.

Awesome! Love seeing well made u-boats in this game. I can't wait to try it.

In the next day or two I will be releasing my new, Built from the ground up and most ambitious U-Boat yet : Greywolf. Will add some sneak peeks tomorrow if I don't get it uploaded by then.

Also : @старая ворона Your U-2540 did give me ideas xD

Awesome

I will have a look through it to be sure.. first glance on the workshop page is very impressive :)

Feel free to borrow some ideas from my U-2540. Your sub played a part in its creation after all.

I try to keep it working at least :)

Hey, cool to see you're still working on this. This is the sub that inspired me to start making my own. Good to see it's getting some more love.

Added Mk3 prototype for playtesting. Redesigned the lighting system, water/breach alarm system, and lower airlock. Hopefully more optimized now. Planning on revisiting the electrical system in the future.

Added Wifi channels used to the description of Workshop page, for info to anyone doing custom work to the sub.

Thanks for the quick fix, appreciate the effort :)

Thanks @Morgen for letting me know about the issue with the new patch.

If anyone finds any other issues, please let me know and I'll address them asap.

I've fixed the issues caused by the new patch (I hope).

The battery/reactor issue is fixed, and is actually better now that they finally added a power/load outputs on the reactor. There is a slight delay to switching over to batteries on power loss (switch will not toggle until reactor power reads 0). I'll try and address that in the future.

I boosted the reactor output slightly to account for the drones power drain when docked, so you shouldn't get any power loss there anymore.

I added a status check to the left airlock hatch for the airlocks drain, so now it won't continuously flood the airlock and ballast tank when the hatch is open. This should reduce some depth loss when flooding the airlock.

I did a few cosmetic fixes to the sub and drone, probably not noticeable unless you're really looking. Also the mini junction box in the drones airlock should no longer be able to take damage (I never intended it to be interacted with).

At first glance in the editor, it looks like they removed the ability to attach more than one wire to the reactors power output, which completely fries my detection setup for the reactor. May be a bit before i figure a work around for it.

Ill try to take a look at it as soon as I can, to confirm (and fix) any broken things with the latest update.

It seems like this is broken with the latest cave update. The batteries never charge, and it's always stuck in backup power. While the reactor does provide power to things, it causes it a bit of jank.

Ahh... yea, I seem to have forgotten to make that one interactable.. theres also a exit in the middle ballast tank through the bottom of the sub.

No, I meant actual people. I discovered the left airlock works. Some people have trouble repairing the shuttle small junction box as they can't touch it, the one in the airlock. outside of the shuttle, if the hull on it is damaged, it can't be repaired in the front.

I've never actually tested its max depth xD As for the AI... not sure, recent updates may have changed the waypoints or something... I know they *used* to work well enough.

Crew is a little confused on how to get out as well.

What is the max depth? It's a nice vessel as is.

Glad you enjoy it... It started out as a project for myself and a few friends who wanted a u-boat type sub to play with... decided to upload it for everyone to use as they saw fit. I'm happy it served you well. :D

Thank you Ankhimas for this sub, I heavily modified it and turned it into my best submarine yet, with additional suits in the ballast (for safety), and more storage overall throughout the sub. This ship has served many a crew very well, and comes back from even a nuclear detonation startlingly well.

When Germany gets to europa

Well you certainly got one, that has served my friend and I well, even survived taking on a boss moloch from XanMonsters (tho the crew died, I didn't) lol

No problem, and Thanks for the compliments. The Mk2 took about a week I think... but I had solved most of the problems/systems/setups with the build of the Mk1. I think the Mk1 took about 2-3 weeks, but she was my first sub build ever.

My friends and I had just tried the game, and we wanted a U-boat xD

That's awesome, I never would have noticed that. Appreciate the awesome sub you made, must have taken you forever to create something this well made.

@Helbrecht

Select the component and there is a toggle to make it interactable, once set you can use the screwdriver.

I always turn it off after I wire components so i don't accidentally break things xD

I was wondering how you had your captains periscope wired, I've been trying to add 2 more searchlights to the periscope but it hasn't worked so far, I found your cluster of components but none of them are able to be selected with the screwdriver to see how it was wired, its been my favorite sub of all time, just trying to put my own flair into it as I progress in campaign.

there is a issue with quest boxes spawning in the hatch that connects to the stations. me and a friend did a bomb transport mission and we ran into a observer from xanmonsters2 mod that when it attacks it sent a emp through the ship causing the bombs to explode. we didn't realize that the bombs kept spawning inside the hull right in between the bridge and the docking hatch. please fix this

@ Jaime
I'll look into that. Not sure there is a way to detect a breach, just flooding in a compartment.

@Helbrecht
Turn off reactor, place rods. Turn on reactor.
Bring up the right slider first (usually around 80-90%).
SLOWLY bring up the left slider to a stable temp, then hit the auto switch.

If you go too fast the heat will build up so fast it triggers the automatic shutdown.
Hope that helps.

i realized there was a hatch under the sub lol im dumb dont mind me! anyways is there a way to setup the alarm system to sound when there is a hull breach? not just for water?

The reactor was on at all times but not outputting enough, I tried adding another rod but it kept overheating then shutting off due to overheat protection, will try fiddling with it and see if I can find a good medium.

I'll look into both comments when I am able. Until then, I hope this helps some...

@Helbrecht
Double check the Reactor is actually on. By default the sub starts in battery mode.
During the initial battery recharge, there is a heavy draw on the reactor. You should be running it with multiple rods in during battery charges (I usually run with 4).
The AI like to run it with just 1 for some reason, and that may be causing your power loss.
Once the batteries are charged, 1 rod is more than enough to manage the power needs of the sub.

I'll look into both comments when I am able. Until then, I hope this helps some...

@Jaime
Something isn't right there. Even with that room and the ballast below it full of water, its not normally enough water to sink the sub completely. The Fore and Mid ballast tanks should automatically empty to compensate. You may get a bit of drop as the sub attempts to adjust the water volumes, but it should right itself pretty quickly.

That said, if the sub is not set to "hold position", its possible the tanks aren't emptying to compensate, and the sub just keeps dropping. In my testing, the most I've had it drop was about twice the height of the sub.

There is another exit to the sub in the left side of one of the Ballast tanks (the Mid one if I recall correctly) if that one works better for you.

Do I need to do something to the reactor to prevent the power loss happens if using the sub with attached shuttle, I can barely undock without going low power and smashing into the sea floor.

The sub sinks like a rock whenever you exit the airlock with the one diving suit. Ive tried parking up high above a thama and the sub got wreck cause it just filled up with water in that one room and sank.

If you're referring to the flooded compartment lights in the command room, thanks. I don't know of any others with that feature, and I hadn't planned on any more sub builds, but it is very easy to set up on any sub you have in the editor.

All it requires is a water sensor in each compartment wired to a matching light. When water is detected, it sets the lights state to "on". I have mine tied to the same water sensors that open the drain valves and shut the compartment doors when water is detected in the compartment.

Your flood lights warning is amazing!!!!!!!!, could you do a small sub for 3-4 persons with that feature.

Or do you know any other sub that has it and is smaller?
