Serialization of: List<string[]> as JSON

I'm working on a little tool that lets me connect several GameObjects with a LineRenderer. It's possible to connect multiple objects within one line. To store the Data of every connection, I'm saving the GameObject.name of every point in the connection in an array (string[]). Serializing this array as JSON worked without problems.

Next step is to store multipe Lines in a list of arrays (List<string[]>) and store it as JSON, so I can deserialize all my Lines at once.

Here is what I'm doing:

Code (CSharp):

1.  
2. public ConnectionCollectionObject activeCollection; // <- This one is filled by the user by clicking things in the scene
3.  
4. public void SaveConnectionCollection()
5.         {          
6.  
7.             if (activeCollection == null) return;        
8.  
9.             Debug.Log(JsonUtility.ToJson(activeCollection, true));  // result: {}
10.  
11.             string path = Path.Combine(Application.persistentDataPath, id + "_ConnectionCollection.json");
12.             File.WriteAllText(path, JsonUtility.ToJson(activeCollection, true));
13.  
14.             Debug.Log(path + " saved.");
15.         }
16.  
17. /////////
18.  
19. [Serializable]
20.    public class ConnectionCollectionObject
21.    {
22.        public List<string[]> connectionCollection;
23.    }
24.  

...using the same princple like I used when serializing the string[] gives ony an empty .json file.

 

JsonUtility has some limitations on things, so it probably doesn't handle it correctly. Try Json.net instead.

 

Worked thanks!
