Hello, friend. Tks for your post.
I made this video to explain better:
That text it's in the Official Terraria Wiki site, Logic Gates, chapter Faulty Lamps:
Logic Gates
I want to understand what it means, because I want to draw it. Maybe post it on Wikki page, because the text is very confusing (for me ... I am a noob).
You sad in your text: "So they are one way". Correct, but my doubts are these (in wiki text):
1) " A very practical use of this is a one-way wire": What wire? The faulty lamp, the "on" logic gate lamp or the logic gate wire?
2) "Also, this wire can be turned off": Where? What wire? The faulty lamp wire or the logic gate wire?
3) "Making two of these": What is "these"?
4) "(A->B), on (A<-B), on (A<-->B)": What's "A", "B", "<-", "->", "<-->"? They are lamps, wires, ... The wires in the faulty lamp and logic gate?
I don't know, I don't know, I don't know, I don't know ... I'm going crazy because of this
