How can playerprefs save my tower model and its position?

Hi all, i’m trying to make game in android devices, and i want the game can save when quit the application and load again when we want to play it.

My game is tower defense, so we must build tower.

What i want to ask, how can i use playerprefs to save the tower model that i already build and its position?

I only can save and load my gold with playerprefs, but when load the game, the tower that i already build lost and i must build it again, i don’t understand how to save my tower model and its position after i build it.

Can anyone help me here?


I need to save the the prefab of the tower I’ve built.
So when I load the scene again, the tower will still be there with its information, such as level, damage, etc.
