Implementing the Actor functionality by inheritance

Inheritance is the second way to implement a custom Actor. This is commonly done to make a new subclass, which adds member variables, functions, or a Component to an existing Actor class. In this recipe, we are going to add a variable to a custom GameState subclass.

How to do it...

1. In the Unreal Editor, click on Add New in the Content Browser, and then on New C++ Class... then select GameState as the base class, then give your new class a name.
2. Add the following code to the new class header:

   AMyGameState(); 
   
   UFUNCTION()
   void SetScore(int32 NewScore);
   
   UFUNCTION()
   int32 GetScore();
   private:
   UPROPERTY()
   int32 CurrentScore;

3. Add the following code to the cpp file:

   AMyGameState::AMyGameState() { CurrentScore ...
