Coding and creating 2D objects that can be interacted with

Hi.

I am very new to unity and coding and every other aspect of game design. I am trying to make a 2D adventure/explore game and I have been doing okay for now with the help of google but I can not seem to get any objects to become interactive for my character. I would really like some help or links to anything I could use, I don’t understand any code but I really want to work on it.

You may need to define in your head what you want an “interaction” to be. Is it on a mouse click? When the player gets close enough do they press a key? etc. But, aside from that this video should help get you in the right direction:
