Unrealのシフトキーにスプリントアクションをバインドするときに問題があります

Question

スプリントアクションをシフトキーにバインドしようとするとエラーコードが表示されます。エラーは、オーバーロードされた関数 "UInputComponent :: BindAction"のインスタンスが引数リストと一致しないことを示します。私は何が間違っているか正確にはわかりませんが、何か助けていただければ幸いです。ありがとう。

     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); 





    };

問題は対照的に、アクションコールバックがコールバックを軸に、任意の引数を取ることはありません

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

の宣言です。これは、軸とアクションの違いについて考えると意味があります。軸には一定の値、すなわち親指をどれだけ押し込むかを指定できます。アクションはバイナリで、ボタンは押されているかどうかのどちらかです。スタックオーバーフローへhttps://www.unrealengine.com/blog/input-action-and-axis-mappings-in-ue4が
