Hi there,

how can I generate a certain signal (red / green). The "Moon Logic" mod does that, but I don't understand how it does it.



The command does not generate a colored signal for me: I would be grateful for tips.

If I’m understanding what you’re looking for correctly, the color of the signal you generate depends on the color of the wire you transmit it on. So if you wanted to generate a red iron plate and a green copper plate signals, you’d need two separate sources: one transmitting the iron plate with only a red wire attached, and another transmitting the copper plate with only a green wire attached.

In this context, the color is merely indicating which set of wires the signal is traveling across, and it’ll keep them separate until you feed them both into something.

As such, afaik, you can’t actually control this via modding.

There probably is a hidden constant combinator that only has the red wire connected so it only generates a red signal.

Oh, yeah, I didn’t think of it that way. Even if there isn’t one like that, you should be able to connect an invisible red or green wire, right?

A constant combinator is the only way to set signals from LUA script. Having an invisible one with invisible wire is common.
