Serialization List of Object

Unity Engine
1

Hi all,

I want to create a plugin but I have some problem with serialization.
I read a lot of documentation, but still I could not understand it well.

I have this problem:

I have in my script (extend MonoBehavior) an Array of TileDraw objects:

    public TileDraw[] tileToDraw;

Tile Draw is a list of Tile that I have to paint on screen everytime a launche my game.
This is the class:
This is the TileDraw class:

[System.Serializable]
public class TileDraw : ScriptableObject
{
    public TileSet tile;
    public int positionInTexture;

    public void OnEnable() {
        hideFlags = HideFlags.HideAndDontSave;
    }
   
    public static TileDraw Instance(string n, Texture2D s, int p){
        TileDraw tileDraw = ScriptableObject.CreateInstance<TileDraw>();
        tileDraw.Init(n, s, p);
        return tileDraw;
    }

    public void Init(string n, Texture2D s, int p){
        if (tile == null)
        {
            tile = TileSet.Instance(n, s);
        }
        this.positionInTexture = p;
    }
}

In TileDraw I have a TileSet class for store(for now) texture of the tile that I have to draw in this position.
This it the TileSet class:

[System.Serializable]
public class TileSet : ScriptableObject
{
    public string tileName;
   
    public Texture2D texture;

    public void OnEnable() {
        hideFlags = HideFlags.HideAndDontSave;
    }

    public static TileSet Instance(string n, Texture2D s){
        TileSet tileDraw = ScriptableObject.CreateInstance<TileSet>();
        tileDraw.Init(n, s);
        return tileDraw;
    }

    public void Init(string n, Texture2D s){
        this.tileName = n;
        this.texture = s;
    }
}

When I execute the script in EditorMode it works fine, I’m able to create Map and draw Tile directly in SceneView, but when i play the game and stop it, my data is lost… TileDraw in tileToDraw are zero…

I have two other list in my class, and they work well.
I think because there is TileSet in TileDraw.
How can I fix this? Someone explained to me how it works?

Thank You guys :slight_smile:

Find the trick!

All class used in MonoBehaviour are serialized and other classes used in this class don’t need ScriptableObject.

Remove ScriptableObject the magic happen :slight_smile:

Thanks

Let me know if Wildregard’s solution does not work and I’ll take a crack at this.
