Creating a UENUM( )

C++ enum instances are very useful in typical C++ code. UE4 has a custom type of enumeration called UENUM(), which allows you to create an enum that will show up in a drop-down menu inside a blueprint that you are editing.

How to do it...

1. Go to the header file that will use the UENUM() you are specifying, or create a
   file called EnumName.h.
2. Use the following code:

UENUM() 
enum Status 
{ 
  Stopped     UMETA(DisplayName = "Stopped"), 
  Moving      UMETA(DisplayName = "Moving"), 
  Attacking   UMETA(DisplayName = "Attacking"), 
}; 

3. Use your UENUM() in a UCLASS(), as follows:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = 
 Status) 
TEnumAsByte<Status> status...
