16,17)파워 레벨에 따라 속도를 설정함

20~)파워가 늘거나 줄면 호출됨

22) 캐릭터 파워변경

24) 캐릭터 파워를 기준으로 속도변화

24) CharacterMovementCOmponent는 모든캐릭터들에 include 된 것이다.
BatteryCollectorCharacter가 Character클래스에서 상속을 받기 때문이다.
따라서 달리거나 점프하는 등 Biped 타입이 할 수 있는 모든 운동 기능을 이미 구성한
CharacterMovementComponent를 통해 받게 된다.

 

current power와 initial power를 비교해서 어느쪽이 높은지 결졍.

power가 낮아지면 하얀색, 높아지면 빨간색으로 서서히 변한다.
