걸을때, 뛸때 스피드 설정

    [SerializeField] float _moveSpeed;   //뛰는 스피드
    [SerializeField] float _walkSpeed;  //걷는 스피드

Box Coliider 넣으면 모델의 위치(y)가 변함

→ Layer을 이용해서 원하는 값만 체크 할 수 있게 함

• 좀비는 Enemy로 Layer 설정
• Floor는 Floor로 Layer 설정
• int mask = 1<<LayerMask.NameToLayer("Floor");
• if(Physics.Raycast(r,out hit, Mathf.Infinity, mask)~
