UMyObject::UMyObject()

}

void UMyObject::MyFunction()
{

}

만약 C++ Object에 BluePrint를 쓰고싶다면??

UCLASS(Blueprintable)
class FIRSTPROJECT_API UMyObject : public UObject
{
	GENERATED_BODY()
	
public:
	UMyObject();

    // ...

Blueprint를 사용할수 있음을 확인할 수 있다.
실제로 Blueprint를 사용해보자면

이제 Blueprint에서 C++ Object의 변수에 접근해보자.

UCLASS(Blueprintable)
class FIRSTPROJECT_API UMyObject : public UObject
{
	GENERATED_BODY()
	
public:
	UMyObject();

public:
	UPROPERTY(BlueprintReadWrite)
	float MyFloat;

	UFUNCTION(BlueprintCallable)
	void MyFunction();
};
