[ UnrealEngine5 ] 캐릭터 애니메이션

1. BCAnimInstance라는 이름의 AnimInstance 클래스를 생성

2. AnimationBlueprint 생성 [ Skeleton과 상속 클래스 설정 ]

 

3. 애님인스턴스와 소유하고 있는 액터는 상호참조가 가능하다.

AnimInstance

Event

1. NativeInitializeAnimation() : 애님인스턴스 클래스가 처음 생성될때 한번 호출

2. NativeUpdateAnimation() : 매 틱마다 계속 호출

 

AnimGraph

- State Alias 기능을 활용

 

 

4. 애님인스턴스 클래스

5. 애니메이션 블루프린트 설정

Locomotion 캐시로 설정	BlendSpace1D로 Idle/Walk/Run 구성

Jump Alias 생성	Jump보다 늦게 실행되어야 함으로 PriorityOrder를 2로 설정
