I was wondering how I add active schematics like those found on other websites and how do I make sure they are not ruin structures and fully spawn?

Can you post this on the front page or have a direct QA link? I guarantee someday I will forget. XD @Ivorforce

You put the schematics inside the structures/schematics folder (run /#files to find it), do /#convert or /#importschematic and from there you can work with it as a normal structure. They'll only look like ruins if you add a ruins transformer to it.

Please refer to the wiki for more info on this :)

It's really just /#importschematic (which is linked on the wiki) and building a structure from it (which is linked from the wiki). Nothing extraordinary to especially write a new article about...
