In this lecture, the code used to access the ActionMaster class gives a compiling warning:
“ActionMaster must be instantiated using the ScriptableObject.CreateInstance method instead of new ActionMaster.”
That is, you should not use new ActionMaster(); when creating an instance of the class.
Of course, even on Unity 5.5, the code works even if you get the warning, but it’s best practice to conform (Borg style :D) to the Unity requirements.
So, how to do this? It’s actually pretty simple.
Firstly, when creating a new class which doesn’t inherit Monobehaviour, you should always make your class inherit the ScriptableObject class, like this:
public class MyClass : ScriptableObject {//mycode}
Once you’ve added the : ScriptableObject class extension, you can create an instance of your class this way:
MyClass myClassInstance = ScriptableObject.CreateInstance<MyClass>();
This way, you won’t get anymore the warning. For more in-depth information about Scriptable Objects, you can check the tutorial on the Unity webpage.
