1. Program

  a. SetViewBuffer 함수 수정

  b. Update함수 에서 SetViewBuffer함수 실행

void Program::Update()
{
	Camera::Get()->Update();
	SetViewBuffer();
	// 이하 생략
}

void Program::SetViewBuffer()
{
	Matrix view{};
    // Macro : CAM -> Camera::Get()
	view = XMMatrixTranslation(CAM->OffsetX(), CAM->OffsetY(), CAM->OffsetZ());
	viewBuffer->Set(view);
}

 

2. Camera

  a. Free Camera 기능 구현

  b. Follow Target Camera 기능 구현

3. Game Scene

  a. Scene 초기화시 Camera 초기화(pos, offset)

  b. Func 함수에서 'F1', 'F2' 입력으로 Camera Target 설정
