Saving 3d objects to persistent data

I have been working on a simulation game somewhat like good game cafe. And I have been having some trouble with saving the positions of the objects in the scene to persistent data storage. Single its not possible with playerprefs, what would be the best way to go about this?

Single is certainly possible with playerprefs. You just save as a string instead. But playerprefs is generally not a good idea if you’re talking about more than trivial amounts of data. I’d use your own save system. You could use one of the many JSON based serialization systems, or roll your own using your favorite text format, or even go straight binary.

Thanks
