scriptable object variable shows <type mismatch> in the inspector instead of a gameobject 976943

Here is a strange one for you

the code that shows you this behavior is this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Events;
5.  
6. [CreateAssetMenu]
7. public class GameObjectVariable : ScriptableObject {
8.     [SerializeField]
9.     GameObject value;
10.     public GameObject Value{
11.         get{ return value;}
12.         set{
13.             this.value = value;
14.             gameEvent.Invoke ();
15.             Debug.Log (this.value);
16.         }
17.     }
18.     [SerializeField]
19.     UnityEvent gameEvent;
20. }

script that sets the SO's value

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class MakeDummyObject : MonoBehaviour {
6.     public GameObjectVariable dummyOut;
7.     public void CreateDummy(){
8.         if (dummyOut.Value != null)
9.             DestroyImmediate (dummyOut.Value);
10.         if (newThing != null) {
11.             dummyOut.Value = Instantiate (gameObject);
12.         }
13.     }
14. }
