I know that I meant like I am making an element and I need to not conduct to certain other materials that are also conductive like how INWR doesn't conduct to metal or semi conductors, but I probably should've been more specific.
no clue then, go check the source code of inwr or the metals i don't have modding experience
There is sort of a way, but only if you don't actually use sparks. Using custom element behavior, you can give your element a life value whenever a spark is nearby, then have it spread to other nearby particles of itself with no life, then have it spark a specific conductor if its life is the correct value. I can't give a specific example as I don't have access to my Lua mods at the moment, but it should be straightforward.
