Getting data for if an object has already been collected on startup

I am attempting to create a method of saving whether a stone has or has not been collected in my scene on startup. I have done everything I know to do with playerprefs, but the playerpref is for every resource, as there will eventually be a lot of stones. What I want is, if you collect a resource of any kind, including chopping down a tree, picking up a stick, or destroying a bush, to 'know' if it has already been destroyed when the game starts up, and for it to destroy itself if it has... and the only way I know to do this is to create a playerpref for every single collectible thing in the world, which there is a lot of. Thanks for any help!

This kind of idea uses voxel engines these days.

Chunk management etc

They are good at condensing the amount of data so you dont need 1 entry for each item.

Ive never tried this so I am just spitballing here...

Couldnt you just add a playerpref for only the objects that have been picked up rather than storing information for each rock?

Is your world generated at runtime? Theres multiple approaches you can take to getting these rocks into a list of some kind. If they are generated at runtime, when those rocks are placed add them to a list. If the world isnt generated at runtime, creating a "rock manager" script could be achieved by parenting every rock in the game to a single gameobject with this "rock manager". Hopefully your hierarchy is organized enough to be able to click the top most rock and +shift click the bottom rock to select them all, then drop them into the "rock manager" list.

When a rock is picked up, tell the rock manager. Rock manager finds that rocks position in the list and a playerpref could be created (rock at position 52 in the list has been picked up). When the game loads, have the manager to a save check that finds rock 52 and turns him off.

Someday I probably will look into making the worlds randomly generated, or at least the rocks, but currently I am just experimenting with rocks that I place...

getting them in a list some how (either manually dragging and dropping or whatever), saving the spot in the list for rocks that have been picked up, and removing the rocks at that list point with list.RemoveAt(x) on load would be the approach i would take.

Thanks for the help! I will work on getting that to work when I get home.
