List myClass where MyClass : ScriptableObject not working

Questions & Answers

Hey Guys,

I obviously don’t know how to solve this

I have 3 Classes
A, B and C

C : B

B : ScriptableObject

A : MonoBehaviour

in A theres a List

List<B> bList = new List<B>();

now I want to put C into this List with it’s own values

    public class A : MonoBehaviour
        {
        List<B> bList = new List<B>();
        public void AddToList(B bElement) //where I want to add C (or even D : B)
                     // maybe I could call this function this way: A.AddToList(C);
           {
           //and there is the problem - I have to create an Instance of C
           //with 
           //bList.Add(null);
           //bList[0] = (C) ScriptableObject.CreateInstance(typeof(C));
           //but if I do this, no values of C are passed and also it could be D instead of C
           }
        
        }

Does anyone know how to solve this?

Thanks in advice.

If C derives from B

C : B

Then you should be able to automatically put it into any container that holds B.

C myC:
bList.Add (myC);

This is useful when you have methods in B that are overridden in C.

Class B

SetupObject ()
{
    //assign variables of B
}

Class C : B

override SetupObject ()
 {
     //assign variables of B
     //assign variables of C
 }

@RobAnthem had some great advice:

For objects that DON’T derive from the same base class

if B and C derive from the same thing then the list will accept either. If they do not, then only a List will work. Then you can parse out the data like this.
if (myList*.GetType() == typeof(objectB)*
{
(myList as objectB).BProperty1 = 42;
}

AssetDatabase.CreateAsset(newRoomObject, “Assets/Resources/Rooms/” + newRoomObject.RoomName + “.asset”);
RoomObjects tempRoom;
AssetDatabase.AddObjectToAsset(tempRoom = CreateInstance(), “Assets/Resources/Rooms/” + newRoomObject.RoomName + “.asset”);
newRoomObject.requiredObjects.Add(tempRoom);
100% Credit to @RobAnthem for the above. Thank you!
