Unity How to Upgrade Easy Save 3
What's the best way to save and load a world with easy save 3?
Im working on a game where I have the terrain procedurally generated, and I downloaded easy save 3 off of the asset store but I don't know the best way to save my trees, animals, and enemies. The game is 2d and I use perlin noise to generate the tilemap for the terrain, and use the noise to say if a random number is a certain amount and the tile is grass, then spawn a tree. This breaks when I quit the game and load the world up again, because all the trees are randomly generated again. So the terrain is the same, but everything else isn't. I've tried to store all the existing trees into a game object list, but when I loaded the world everything was duplicated and it took forever to load when I had a lot of trees in the world. I also thought of the idea of using a different noise pattern on top of the terrain to spawn the trees but then the problem would be if the tree is chopped down by the player, than it would be fully grown again. Hopefully that all made sense and im hoping there's an easy solution to this. This is the code for generating the world:

@jobothehobo Did you solve it? I'm having a similar issue. My game is 3d, but for a 2d context as yours something like a dictionary with the tile-type could work, having different letters/strings for each state of the tree. I hope you've solved it! Good luck
