class WAVE_API IWvGamePlayAttackerInterface

	// Add interface functions to this class. This is the class that will be inherited to implement this interface.
public:
	UFUNCTION(BlueprintCallable, BlueprintNativeEvent)
	void AddDamageable(const IWvGamePlayAttackerInterface* damageableObject);
};

I get some compilation error. As title, I would like to add an object following same interface.
Any one has feedback.
