Help needed: thinking a way to save item

Unity Engine

Hello,
I’m trying to replicate the rpg / farm type of game like Stardew Valley.

In this type of game, you can leave objects on the ground, save the game or change the scene, then find the said objects left on the ground when you return back.

I present to you the way I intend to manage everything, in the hope that you can either confirm to me that I am on the right track, or show me a simpler and more efficient method.

My method: when the object is instantiate on the ground, create Playerpref then, with each load or change of scene, reload the Playerprefs including the coordinates of the object, then instantiate the objects on the ground again.

What do you think? Is there a simpler or more efficient method?
Is there somewhere au tutorial?

Thanks!

My 5 cents is to choose JSON instead of playerprefs, together with dropped things you will probably end with more information to save, and this also makes it easier to debug. About the approach, it will work, I would just not update my save on every object that going to be instantiated, save on change scene, exit and on errors.
