Mathf.Abs > 절대 값 반환 

 

점프 할때

올라갈때

s: 현재 속도  = (초속 + 가속도 * 시간) * 시간

현재속도 = ( 1    + 9.8f(중력가속도) * Time.deltaTime) * Time.deltaTime;

this.transform.translate(방향 * 속도 * 시간)

 

 >> this.transform.translate(방향 * 현재속도); <<이미 시간 곱했으니 시간 빼고

 

 

내려갈때

 S = (v -at) t 

s: 현재 속도  = (초속 - 가속도 * 시간) * 시간

현재속도 = ( 1    - 9.8f(중력가속도) * Time.deltaTime) * Time.deltaTime;

 >> 방향도 포함하고있다

this.transform.translate(속도)
