ㅜㅜ
기간이 얼마 안남았는데
포풍 코딩해야됨 ㅜㅜ
GetTransform()이게 현재 행렬 내놓는거 맞지?

  D3DXVECTOR2 Center2D;
  Center2D.x=Center.x, Center2D.y=Center.y;
  pSprite->Begin(D3DXSPRITE_ALPHABLEND);
  D3DXMatrixTransformation2D(&RotateMat, NULL, 0.0f, NULL, &Center2D, RotateAngle+(3.14/2), NULL); 
  pSprite->GetTransform(&OriRotateMat);
  pSprite->SetTransform(&RotateMat);
  pSprite->Draw(Texture, &Source, &Center, &Position, 0xffffffff);
  pSprite->End();
  pSprite->SetTransform(&OriRotateMat);

이렇게 하면 되려나
