언리얼엔진5 c++ Old Input System 사용하는 방법 정리

에디터에서 다음 경로로 이동합니다.

Edit → Project Settings → Input → Bindings

여기서 두 가지를 등록합니다.

 

Axis Mappings

• MoveForward
• MoveRight
• Turn
• LookUp

Action Mappings

• Jump
• Attack
• Interact

공식 문서에서도 입력 정의는 Action Mapping과 Axis Mapping을 통해 설정하는 방식으로 안내합니다. 

• MoveForward
  • W = 1.0
  • S = -1.0
• MoveRight
  • D = 1.0
  • A = -1.0
• Turn
  • Mouse X = 1.0
• LookUp
  • Mouse Y = -1.0 또는 1.0

Action Mappings

• Jump
  • Space Bar
• Attack
  • Left Mouse Button
• Interact
  • E
