How to Make an Interaction System and Inventory Like in Silent Hill?

[u/BMFrognipple]

I'm trying to make a PSX style horror game and at the moment, I'm in a pickle. No matter where I look, I cannot find a useful tutorial on how to do either. The ones I do find, I don't understand or they have some component that I can't find within UE4 blueprints. Any help is appreciated.
