[ UnrealEngine5 ] 입력 시스템 설정(Inhanced Input)

Inhanced Input

1. InputMappingContetxt, InputAction 생성

IputMappingContext 생성	InputAction 생성

 

2. TObjectPtr<class UInputAction> MoveAction

 

에디터에서 생성한 InputAction, InputMappingContext를 맵핑시킬 포인터 변수를 생성한다.

3. 포인터 변수에 생성한 InputAction과 InputMappingContext의 경로를 설정하고 바인딩

4. InputMappingContext와 InputAction 내부 설정

IA_BCMove, IA_BCLook = Axis2D로 설정

IA_BCJump = Digital(bool)로 설정
