How do I make a point and click interactive objects?

I'm trying to make a point and click like MacVenture Series or Norcos, where you have a background and can interact with it, like taking itens, going to other room, and etc..

First I tried this using invisible sprites with different instance variables to the interactive objects, but noticed that when changing rooms (aka: background image) I would have to mannualy change the sprite size, position and instance variable. And the last one I think is not possible with multiple interactables.

I'm thinking about using separated sprites for each interactive object and using separated layouts. but I don't think it would be the best Idea.

So I wanted you guy's opnion. How would you do this?

Yeah that's the best idea unless it makes more sense to change the background in the same layout and spawn objects based on stored co-ordinates.

Really? Making a lot o layouts and sprites will not have some impact in the game's performance?

The opposite actually as it only loads what is in the current layout. Putting everything in a single layout is where you would have the performance issues, though I believe there is something where you can unload graphics that are not being used if you prefer to do it that way.

I don't think I want to hahaha I think is simplier like this, thank you!
