Nice idea! Could be simplified a bit though. There's not need to use the sonar data signal (if connect 2nd AND input with osc too), since the transducers are only there to provide power consumption and decoration. But the way it's wired doesn't make that obvious at first glance.

@Eh Luigi
This isn't silent.
If you take this into a Sub Editor, enable debugai, freecam and aitargets commands, in this order (remember to activate the Passive Sonar from this mod you brought it, wire it together, etc).

What happens it pulses a max sound level like an engine, and then reduces down to 0 again.
But it is "incosistent" and "often" to the point where I know it will drag every monsters too you if they were close to you.

So no, this isn't silent.
But it is creative to use "sound" to reflect the surrounding aspects in passive sonar for the captain.
But at that point, it is better to use Active Sonar if you want to know everything at all times.

Question: is it also silent? if not then is it more silent then the active sonar?

@crazy Ivan

Ivan I was able to figure out the issue. your false output on the AND component needs to be left blank. it cant be zero or it just starts going out of whack. it may be when you bring it into assembly the blank false input is being changed to a zero

@ActuallyUlysses interesting, I don't know why the Transducer would behave that way. If you link to your sub I'm happy to investigate. Regardless I'm glad you were able to adapt the concept to your needs.

@Crazy Ivan
Ye no worries.

Basically, your condition for assembly to start is for the transducer to receive continuous signal, so that AND component can "catch" signal from other components of the assembly.

In some conditions transducer will not send any signal, so even though you power it, AND will not give any output, so the assembly will not work.

Now, I don't know why transducer sometimes is not sending any signals, but that happened with my sub and led to confusing results.

Anyway, I created a bit more complex assembly and fixed it for my set up. Still, the idea to use noise generating devices to "extend" the range of passive sonar is genius within itself.

Ah, gotchya.

@Mantha no it's a vanilla item assembly not a mod. When you subscribe to this mod it'll add the Passive Sonar Display to your Sub Editor's Item Assemblies. From there you can paste it into whatever sub you're editing and wire it up to the Nav Terminal or a button or other circuit—that's up to you.

So can players simply install this mod and expect to see the "Toggle Passive Sonar" button appear on the navigation terminal, or do we have to get a button and wire it up?

(Whoops, sorry for deleting your comment; Steam lagged at the worst possible time.)

Wiring the transducer that way is to detect when power is supplied to the Passive Sonar Array because the transducer outputs its meaningless-but-truthy data signal when powered and sends no signal when unpowered. So the AND can only be activated when the Array is powered.

What do you mean about more confusing than helpful? I'm open to feedback on what's missing or how it can be improved.
