JSON Serializing problem

Hello there,

I am having trouble using the JsonUtility.ToJson function. The answers I find online are confusing, I am trying to serialize a List of a custom type, which is a plain class that only includes int, bool and float. All of the variables are public and the class has an Serializable attribute. On the Unity docs I see it says "passing an array to this method will not produce a JSON array containing each element, but an object containing the public fields of the array object itself (of which there are none)." To me it looks like that a list woulnd't work either however I have read about people using this to serialize a list so I am very confused right now. This is the code:

Code (CSharp):

1.  [Serializable]
2.     public class AnimData
3.     {
4.         public int id;
5.         public int type;
6.         public bool dirty;
7.         public float Value;    
8. }
9.  
10. //I use the following line to serialize
11.  
12. string data = JsonUtility.ToJson(DataList);
13.  

On Debug.Log it show the string data as "{}", I am a 100 percent sure the list contains items, I have a debug right before the serializing to check for the list count.

Thanks in advance

 

You can’t pass a list directly to the ToJson() method, just like with arrays.

All you have to do is put the list in a wrapper class and serialize that class.

Code (CSharp):

1. [Serializable]
2. public class Data
3. {
4.     public List<AnimData> data;
5. }
