Static Const Variable Declaration

Development Programming & Scripting
1

Hi, I am kind of newbie for C++. I actually come from JAVA world :slight_smile: The thing I am trying to do is to create some static and constant variables. However, I could not. Actually I succeeded when I create MIN_VOLUME variable only but it failed when I added more. Can someone lead me what the real problem is and how to succeed?

Header File:

class THECLOUD_API ACloud : public AActor
{
	GENERATED_UCLASS_BODY()

	static const float MIN_VOLUME;
	static const float MAX_VOLUME;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = FlyingObjects)
	float chargeLevel;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = FlyingObjects)
	float currentVolume;
	
};

CPP File:

#include "TheCloud.h"
#include "Cloud.h"

const float ACloud::MIN_VOLUME = 1.f;
const float ACloud::MAX_VOLUME = 10.f;

ACloud::ACloud(const class FPostConstructInitializeProperties& PCIP)
	: Super(PCIP)
{
	chargeLevel = 0.f;
	currentVolume = MIN_VOLUME;

}

Error I get:

error C2059: syntax error : 'constant'
error C2238: unexpected token(s) preceding ';'
error C2059: syntax error : 'constant'
error C2238: unexpected token(s) preceding ';'
error C2589: 'constant' : illegal token on right side of '::'
error C4091: '' : ignored on left of 'const float' when no variable is declared
error C2143: syntax error : missing ';' before '::'
error C2059: syntax error : '::'

ADDITIONAL INFO

  • Strange things happen. The code below compiles fine :confused: Is this a compiler bug issue or what?

    UCLASS()
    class ACloud : public AActor
    {
    GENERATED_UCLASS_BODY()

     const float VOLUME_MIN = 1.0f;
 const float VOLUME_MAX = 10.0f;

 UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = FlyingObjects)
 float chargeLevel;

 UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = FlyingObjects)
 float currentVolume;

    };
