UpdateLighting(Light lightSource, Gradient colorGradiant, AnimationCurve intensityCurve)

float intensity = intensityCurve.Evaluate(time);

• 애니메이션 커브에서 시간별(x축) y의 값을 intensity 에 저장

• lightSource.transform.eulerAngles = (time - (lightSource == sun ? 0.25f : 0.75f)) * noon * 4.0f;
• 햇빛의 각도를 시간별로 조정

• lightSource.color = colorGradiant.Evaluate(time);
• 시간에 따른 색상값

• if, else if 문
• sun 의 intensity 가 0 일때 time 이 0 ~ 0.2, 0.8 ~ 1.0 일때 sun setActive(False)
• 
• Moon 의 intensity 가 0 일때 time 이 0.3 ~ 0.7 일때 setActive(False)
