So, I'm trying to make my own room. I've learned a couple things so far watching a tutorial video. But any hints or suggestions on how to do things would be nice. Especially on how to move around better.

My main questions of curiosity though are this: 1. How do I add my own sound effects or music?

2. How do I add custom items? Like how would I add say a food item that isn't in the game. Or a weapon? How do you create things to put in?

Thanks
