Ich habe Probleme beim Binden einer Sprintaktion an die Umschalttaste in Unreal

Question

Ich erhalte einen Fehlercode beim Versuch, eine Sprintaktion an die Umschalttaste zu binden. Die Fehlerzustände, keine Instanz von überladenen Funktionen "UInputComponent :: BindAction" stimmt mit der Argumentliste überein. Ich bin mir nicht sicher, was genau falsch ist, aber jede Hilfe würde geschätzt werden. Vielen Dank.

    const FRotator Rotation = Controller->GetControlRotation(); 
    const FRotator YawRotation(0, Rotation.Yaw, 0); 

    //By using the X axis, the character will now move forward and back. It will scale along the X axis by moving forward, which

} 

Und hier ist mein .h Code:

    UCLASS()

     GENERATED_BODY() 

    public: 
     // Sets default values for this character's properties 
     APenmen(); 

    protected: 
     void EndSprint(); 
     // Called when the game starts or when spawned 
     virtual void BeginPlay() override; 

    public: 
     // Called every frame 
     virtual void Tick(float DeltaTime) override; 

     // Called to bind functionality to input 
     virtual void SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) override; 

     //This sets up the methods for character movement and will grab the Value (1.0 for moving forward and -1.0 for moving backward from Unreal 
     //for how fast to move when the corresponding key is pressed 

     void MoveForward(float Value); 

     //This sets up the methods for character movement and will grab the Value (1.0 for moving right and -1.0 for moving left from Unreal 
     //for how fast to move when the corresponding key is pressed 
     void MoveRight(float Value); 

     void OnStartSprint(float Value); 

     void OnEndSprint(float Value); 





    };

Das Problem ist die Erklärung von

void OnStartSprint(float Value); 
void OnEndSprint(float Value); 

Aktion Rückrufe haben keine Argumente nehmen, im Gegensatz Rückrufe zur Achse. Dies macht Sinn, wenn Sie an den Unterschied zwischen Achsen und Aktionen denken. Achsen können einen bestimmten Wert haben, d. H. Wie weit dein Daumenstift gedrückt wird. Aktionen sind binär, Ihre Schaltfläche ist entweder gedrückt oder nicht. So müssen Sie die Erklärung zu

void OnStartSprint(); 
void OnEndSprint();
