Hi! Welcome to the site.
As for coding, like others have said, it depends on the story you plan on making.
Strictly speaking, no knowledge of coding is needed at all!
However, if you plan on making a game that would require coding (see TCat's examples in her post) then have no fear! There are plenty of people here willing to answer some questions, but of course you should check out the articles and try to figure things out for yourself first. If you're starting from scratch, try this article here.
Hope you enjoy your time on this site!
