Issue with JSON serialization

I'm trying to serialize an array of custom Monobehaviours, using JSON. I know it can't be done directly, so I'm using a wrapper class and serializing that instead.

This is the wrapper object

Code (CSharp):

1. [System.Serializable]  
2. public class WavesCollection {
3.     public Wave[] waves;
4. }

That's the object being wrapped (only the important bits of it)

Code (CSharp):

1. [System.Serializable]
2. public class Wave : MonoBehaviour {
3.     [SerializeField]public float[] AppearTimes;//at that time should the n-th enemy appear;
4.     [SerializeField]public Vector2[] positions;//where should the n-th enemy appear;
5.     [SerializeField]public EnemyType[] EnemiesToAppear;//what enemies should appear
6. }

Code (CSharp):

1.         wavesArray = new Wave[] {thisWave, thisWave, thisWave};
2.         WavesCollection collection = new WavesCollection();
3.         collection.waves = new Wave[10];
4.         wavesArray.CopyTo(collection.waves, 0);
5.         StreamWriter sw = File.CreateText(WritePath);
6.         string json = JsonUtility.ToJson(collection);
7.         sw.WriteLine(json);
8.         sw.Close();

And that's the code that does the serializing. Basically I've got an array of non-null Wave objects and I copy that to the wrapper object. I then try to write that in a file and the output is

Code (JavaScript):

1. {"waves":[{"instanceID":-99992},{"instanceID":-99992},{"instanceID":-99992},{"instanceID":0},{"instanceID":0},{"instanceID":0},{"instanceID":0},{"instanceID":0},{"instanceID":0},{"instanceID":0}]}
2.  

Could anyone give me a few directions on what I'm doing wrong?

 

You're still trying to serialize a MonoBehaviour instance directly. Wrapping it in another class won't do anything. You need a "WaveData" class that holds the values in Wave that you care about. Then you can serialize a collection of WaveData.

 

That's not the case as I can serialize Monobehaviours directly without issue. The problem is that I can't serialize arrays of objects with Unity's JsonUtility.
