C#유니티 기반 VR 컨텐츠 개발 16일차

Mesh Renderer 에서 

Cast Shadows : 조명을 받으면 그림자를 만든다 연산량 어마어마함

Receive Shadows : 그 만들어진 그림자를 받는다. 어마어마함

Use Light Probes, Reflection Probes : 연상량 어마어마함

※ 빈 프로젝트를 만들어서, 그곳에서 테스트후 본 프로젝트로 옮기는 방식을 취하자, 

※ LeanTween :

   LeanTween.move( 누가 , 어디로, 얼마동안 ). 어떻게  이동

LeanTween.roatate( 누가 , 어디로, 얼마동안 ). 어떻게 회전 

LeanTween.scale 크기

ex ) LeanTween.move(gameObject, target, 5.0f).setEase(LeanTweenType.easeInOutExpo);

LeanTween.scale(gameObject, Vector3.one * 2, 1.0f).

setEase(LeanTweenType.easeInOutBack).setLoopPingPong(4);

   최종 마지막 하나만 더있으면 되다. 바로 Value 에 대한 변화

valutTo

onstart : Tween 애니메이션이 시작할 때 호출할 함수

onupdate : Twee 이 진행되는 과정중에 매 프레임 호출할 함수

oncomplete : Tween 애니메이션끝나면 호출되는 함수

onXXXtarget : 호출된 함수를 들고 있는 GameObject

ignoretimescale : 이 옵션값이 true 로 설정되어있다면 Time.timeSclae 이 0이어도 TWEN 앤메이션을 재생하게함. FLASE 면 다 멈추면 자신도 멈춤

※ LeanTween 반환값은 LTDescr 이고 이걸로 받은다음에 이제 위의 onStart 등을

 설정할수 있다.

LTDescr desc = LeanTween.rotate(gameObject, targetRotation, time).setEase(LeanTweenType.easeOutExpo);

            LeanTween.scale(gameObject, Vector3.one, scaleTime).setEase(LeanTweenType.easeOutElastic);

            desc.setOnStart(TweenStart);

            desc.setOnUpdate(TweenUpdate);

            desc.setOnComplete(TweenComplete);

※ 각각 실행될 함수들을 지정해주는것 일종의 Delegate로 

Ontart,OnComplete 는 void 형 인자 없는 형태를,

Update 는 void 형태의 float 하나를 인자로 받는다.

        }

    }

    void TweenStart()

    {

        Debug.Log("Start");

    }

    void TweenUpdate( float percentage)

    {

        Debug.Log("Update" + percentage );

    }

    void TweenComplete()

    {

        Debug.Log("Complete");

    }

Value 어떻게 쓰는가 ! 

            LTDescr desc = LeanTween.value(gameObject, 0.0f, 255.0f, 1.0f);

            desc.setOnStart(TweenStart);

            desc.setOnUpdate(TweenUpdate);

            desc.setOnComplete(TweenComplete);

이렇게 하고 이제 

    void TweenUpdate( float value)

    {

        Debug.Log("Update" + value );

     mat.color = Color.Lerp(Color.black, Color.green, value / 255.0f);

    }

TweenUpdate 함수 가 저 변하는 value 값을 float로 받아온다. 이걸 사용하면 된다.
