Question by LRP · Jan 20, 2019 at 10:03 AM · listserializationgeneric

Serializing a List of generic classes

Hello,

I am trying to create a look up table for ScriptableObjects. I am unable to have Unity serialize a list of generic classes though. Any ideas on how I can fix that or how I can make my look up table differently ?

Here is my class:

 public class LookUpTable<T> : ScriptableObject where T : ScriptableObject
     {
         [SerializeField]
         private List<TableEntry<T>> Elements = new List<TableEntry<T>>();
 
         public int GetKey(T value)
         {
             for (int i = 0, j = Elements.Count; i < j; i++)
             {
                 if (Elements[i].Value == value) return Elements[i].Key;                
             }
             return -1;
         }
 
         public T GetValue(int key)
         {
             for (int i = 0, j = Elements.Count; i < j; i++)
             {
                 if (Elements[i].Key == key) return Elements[i].Value;                
             }
             return default(T);
         }
     }
     
     [Serializable]
     public class TableEntry<T>
     {
         public int Key;
         public T Value;
     }

Thank you
