Error : Invalid BlueprintType enum base - currently only uint8 supported

Simple replace line 3 with:

enum class EMyState : uint8

This ensures your enum derives from uint8, just like 4.15 wants.

I am following one of the ue4 c++ tutorials but in 4.15 I get the following error

error : Invalid BlueprintType enum base - currently only uint8 supported

//enum to store the current state of gameplay
UENUM(BlueprintType)
enum class EMyState
{
	EPlaying,
	EGameOver,
	EWon,
	EUnknown
};

I am a beginner and don’t know how I must replace this to make it work for 4.15

Just a note for others. If you are still getting an error like “error : Invalid BlueprintType enum base - currently only uint8 supported”, it seems 4.26 may have changed how this all works although I see the engine uses this syntax still.

I am managing to get the following to compile:

UENUM(BlueprintType)
enum ESomethingSomethingEnum {
	TopRight
	UMETA(DisplayName = "Top Right"),

	BottomRight
	UMETA(DisplayName = "Bottom Right"),
}

but cannot get:

UENUM(BlueprintType)
enum class SOMETHING_API ESomethingSomethingEnum : uint8 {
...

to compile.
