VaFogBlockingVolume SetLayer dynamically

[Tipnos]

Hi,

For gameplay reason I would like to be able to change layer of VaFogBlockingVolume. I added this peace of code locally:

AVaFogLayer* AVaFogBlockingVolume::SetLayer(AVaFogLayer* InLayer)
{
	Layer = InLayer;
	if (Layer)
	{
		Layer->AddFogBlockingVolume(this);
	}
	else
	{
		Layer->RemoveFogBlockingVolume(this);
	}

	return Layer;
}

class VAFOGOFWAR_API AVaFogBlockingVolume : public AVolume
{
	GENERATED_UCLASS_BODY()

	//~ Begin AActor Interface
	virtual void PostLoad() override;
	virtual void PostActorCreated() override;
	virtual void OnConstruction(const FTransform& Transform) override;
	virtual void Destroyed() override;
	//~ End AActor Interface

#if WITH_EDITOR
	virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override;
#endif

private:
#if WITH_EDITORONLY_DATA
	UPROPERTY()
	UBillboardComponent* SpriteComponent;
#endif

public:
	/** Set Layer dynamically */
	UFUNCTION(BlueprintCallable, Category = "VaFog Blocking Volume")
	AVaFogLayer* SetLayer(AVaFogLayer* InLayer);

	/** Height level where agent is standing */
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "VaFog Blocking Volume")
	EVaFogHeightLevel HeightLevel;

	/** Volumes will affect terrain level being sorted by Priority */
	UPROPERTY(BlueprintReadOnly, EditAnywhere, Category = "VaFog Blocking Volume")
	int32 Priority;

protected:
	/** Target layer to paint on */
	UPROPERTY(BlueprintReadOnly, EditAnywhere, Category = "VaFog Blocking Volume")
	AVaFogLayer* Layer;

	/** Process volume bounds and apply its influence into terrain map */
	void UpdateTargetLayer();

	//////////////////////////////////////////////////////////////////////////
	// Debug

public:
	/** Debug fog layer affect */
	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Debug")
	bool bDebugVolume;
};

Are you ok to add it ? If so I can make a pull request.

Thanks
