Logic Circuitry Question

[Lucien Lachance]

Trying to make it so that when the Siren in my settlement activates, it closes a door instead of opening it. How can I achieve this? I've tried for hours with no success. I have a lot of experience with logic gates as well from Minecraft and many of its mods and some other choice games including LBP2. Can't figure out how they have it set up in FO4.

Well.. forget all your experience, because FO4's advanced switch logic tables are broken.

Whatever gate you have, if all the inputs go low, it's dead... output is low. Even if the gate is supposed to be high on all inputs low, it'll go output low. That's because it's powered by the inputs... no power, no output.

Now, that aside, the negated logic will not 'power' anything but another gate, so using one means you'd need to buffer the output with an AND gate, where the previous gate output is input 1 and a live power feed is input 2. You may find that you have to buffer some inputs in the same manner.

You'll have to get creative... you may need to grab a sheet of paper and grid out the various (il)logic tables if you want something complex.

Oh, and btw, gate feedback is right out. Don't even attempt feeding back to an input further back up the chain, because it'll just bug out and break switches (they get in wierd states that won't go away until they're scrapped and rebuilt).

I've posted on the bethesda forums various ways to fix these issues without too much work on their part, no idea if that'll ever appear in a patch or not. There are mods that provide advanced switches that work properly, if you're not afraid of such things.

omg how difficult can it be Beth to use conventional logic gates,
AND gate
OR gate
NOT gate
NAND gate
NOR gate
EOR gate
ENOR gate.
?

XOR and XNOR. They *did*... but then they introduced an ancillary condition that results in a broken table. That's part of what I wrote on their forum, letting the things "work" on radiant power would fix everything wrong with the tables, without needing to re-make the graphics and meshes to accomodate a new/third power input pole.

Tim Timsen you're a joke. I specifically said Minecraft and its mods, including Voltz, Tekkit Classic etc which definately had NOT, AND, XOR, OR and all the other gates in its redstone logic, not to mention Lua coding in the computers themselves (In base Minecraft I built the gates myself, made incredibly intricate time-synchronized traps and wired entire dungeons together with door systems and everything). If you're trying to troll just stop and gtfo. As for what you said mfree I didn't realize they were broken, glad someone knows. Would the unofficial patch fix it by any chance? I know the mod is out already. As for what you were saying about the whole puzzle I'd really have to take some time and paper because that seems pretty complicated. If I happen to get it working I'll post a screenshot(s) here.

It's not that complicated. You just take the regular table, and if there's a condition where both inputs are low (or for more than two inputs, *no* inputs are high), and output was supposed to be high, scratch it out... it'll be low.

It seems unlikely the UOFP fixes it, but I don't know for sure. From what I have seen, logic gates work fine when no inputs have power as long as you are connecting to other logic gates, you just need to use work arounds for connecting to other devices. For the feedback issue, you just have to make sure that the output of a logic gate can't be traced back to its input through the power system. There are other ways of making circuits that require that using switches that toggle when an item goes through them. You can put an item through using a hopper onto a conveyor (my personal favorite), ball tracks, or using the conveyor diverters to bounce an item back and forth. There are probably other methods as well.

Just use Advanced Settlement Power by cadpnq. Logic done right, plus a few extra things that make Contraptions much nicer.

I'll definately be trying this out.
