Best method to save a multi-dimensional array as a file?

Here is the code for Deserializing a saved game again:

 public static void Load(string gameToLoad) {
         if(File.Exists("C:/Savegames/" + gameToLoad + ".sav")) {
             BinaryFormatter bf = new BinaryFormatter();
             FileStream file = File.Open("C:Savegames/" + gameToLoad + ".sav", File$$anonymous$$ode.Open);
             loadedGame = (Game)bf.Deserialize(file);
             file.Close();
             Debug.Log("Loaded Game: " + loadedGame.savegameName);
         }
     }

This belongs into the SaveLoad script from the answer above because it uses the loadedGame variable. Once this variable hold a reference to our deserialized Game variable, we can then access this variable as usual. Note that for my own project, I used an array with only three dimensions, so you need to modify the code to correctly increase the iteration variables :) $$anonymous$$y tip is to take a piece of paper and a pen and write the whole loop system down and then think how it works and how a fourth dimension can be added. Shouldn't be too hard with the code below.

 //ClearScene();//If you want, you can call a function like this that just checks each gameobject in the scene wether it is somehow marked as "please don't destroy me if a game is loaded", like a game manager would, or a player object or something. All objects that need to persists. Of course, this would be the same as when switching scenes.
         
         SaveLoad.Load("blubb");//call the Load function and pass it a the name of the saved game file to load. 
 
         Game loadedGame = SaveLoad.loadedGame;//cache our loadedGame variable from the SavedLoad static class
 
 
         int a = 0;
         int b = 0;
         int c = 0;
 
         for(int i = 0; i < loadedGame.flatBoolArray.Length; i ++) {
 
             my$$anonymous$$ultiArray[a,b,c] = loadedGame.flatBoolArray[i];
 
             c++;
 
             if (c == my$$anonymous$$ultiArray.GetLength(2)) {
                 c = 0;
                 if(b < my$$anonymous$$ultiArray.GetLength(1) - 1) {
                     b++;
                 }
                 else {
                     a++;
                     b = 0;
                 }
 
             }
         }

$$anonymous$$any thanks again! This will go to good use. $$anonymous$$arked as correct answer as well.

$$anonymous$$y pleasure. It took me a long time to get the loop right so it's good that someone else can use it :D

Oh, I jsut noticed that you actually used a three-dimensional array in your example as well.. I somehow assumed you used a fourth dimension :D In that case, the DS code needs no modification, and in the answer, the outermost or innermost cycle can be deleted and the flat array's length isn't multiplied by it as well.

I also recommend taking a look at the Uniter Serializer, a free asset available on the asset store. Very comprehensive and powerful, although for complex projects it's possible that it breaks down and gives errors, and it gets no further updates but hey it's free and it is a great source of information about advanced serializing.

I've followed this and it's been super helpful, however when I try to deserialize it throws me a null error on my array. It reads the loaded array in fine but that loop you have at the end doesn't work for me :(

 for(int i = 0; i < loadedGame.flatBlockArray.Length; i++) 
 {    
     blocks[a,b,c] = loadedGame.flatBlockArray[i];
                     
     c++;
                     
     if (c == blocks.GetLength(2)) 
     {
         c = 0;
         if(b < blocks.GetLength(1) - 1) 
         {
             b++;
         }
         else 
         {
             a++;
             b = 0;
         }
                         
     }
 }

blocks is null and it throws this error: NullReferenceException: A null value was found where an object instance was required.
