[UE] 활 조준

지난 시간에 이어 활 조준을 구현해보자. 활의 BlendSpace 1D를 만든 것처럼 플레이어 애니메이션도 BlendSpace 1D로 만들어 활 조준을 자연스럽게 구현할 것이다.

함수 추가 - 우클릭 했을 때 조준되고 때었을 때 조준이 해제되도록 하는 역할

AR_Aim2 생성  +  애니메이션 5개의 Base Pose 애니메이션으로 설정

 

 

AR_ShootAndDraw 복제하여 AR_Aim2 생성 - 0프레임 제외하고 제거(=프레임 1에서 프레임 38까지 제거)

 

 

애니메이션 편집

• AR_Aim_C, AR_Aim_D, AR_Aim_90, AR_Aim_U, AR_Aim_U90 선택
• 애셋 액션 - 프로퍼티 매트릭스를 통한 대량 편집

 

1. 다섯개의 애니메이션 선택
2. Base Pose Animation
   1. 애셋 선택 - AR_Aim2 선택

함수 정의

• void UCAnimInstance::NativeUpdateAnimation(float DeltaSeconds)

    • SubAction이 true라면(=SubAction 실행중이라면) bBow_Aiming을 true로, WeaponType을 Bow로, GetInAction()을 true로 만들어준다.
