Hi, I have created a procedurally generated 2D game, a little like minecraft. How would I save the changes to the world and load them in the next time you play in that world? The world is procedurally generated by the seed. Right now I can save the world but I want to be able to efficiently save the…

I think you should not build the world from seed again, but save all objects relevant variables and properties. If your map is chunked, you can still use your seed for the not generated (and therefore untouched) chunks. Or you split all objects in two categories: World objects that are fixed and …

How would I set about checking if a item is saved already and loading it into the game?

I don’t quite get, what you mean by that. You need to load everything back into the world anyways. If you create two categories (which is probably not adviseable, if your generation algorithm is complex), then you don’t “check” what needs to be loaded individually and what can be generated, but you…

All objects must be able to be interacted with, so I can’t actually split into two groups of objects unfortunately. And also only the area around the character is loaded in at a time. So objects further away are deleted.

Oh, that means you already need to save the variables and properties of manipulated objects at runtime anyways. In that case I would build a structure of tiles, that save all needed information (I don’t see how you specifically do it, but your world looks like a grid to me). Whenever you load the ga…

This made me realise that id forgotten to do something in my game and that’s save the objects that move about in the world (Irecently moved them to another array.array.structure) to storage and so anyone coming back to the game world have had a world with no aliens …doh! …done it now! If you’ve got…

That’s quite a good solution! However, its an infinitely procedurally generated world, does that mean my scene will have an infinite amount of tiles at the start or should I create them as I go along? Thanks for the tips

Unfortunately, I can’t create the entire procedurally generated world at the start, it is infinite.

Once you’ve created it - where are you storing it? - does it just exist as objects or are you saving everything in a structure?

How to save changes to a procedurally generated game?

How do I...?
