Question, is there any code for a hack and slash platformer in Renpy?

If not, then how would I code this?

Ren'py does not make it easy to do any kind of platformer. I believe it's built on top of pygame so if you want to learn that you'll be able to use it within renpy, but this forum is probably not the right place for pygame questions.

You can but I don't see why you would.
If that's what you are after just uses Pygame instead of Renpy or better yet, just use something like Godot.
