InputAction

Value타입에 필요한 값 설정
MoveAction이기 때문에 Vector2D

Input Mapping Context

Modifiers

• Swizzle Input Axis Values : 입력 받을 값의 축을 설정

• Negate : 반대 값 설정

인풋 액션 생성자에서 초기화
BeginPlay 에서 InputMappingContext 적용

BP_PlayerController

블루 프린트에서 설정

BP_GameMode

게임모드에서 설정한 컨트롤러 블루프린트를 적용

Bind

BindAction(Controller에서 설정한 InputAction,입력 이벤트 종류 , 대상 , 실행할 함수)

EX

컨트롤러가 바인딩된 엑터에서 입력에 맞게 바인딩된 함수를 실행한다
WASD를 누르면 Vector2D의 값이 FInputActionValue& 의 value로 들어온다

MoveInput을 활용해서 캐릭터를 움직인다.
