Doyoon Kwon… Is Dmitry’s reply same with your solution?

한국어 : 권도윤님, 혹시 해결책이 답글에 달려있는 스레드에서 말하는 방법인
CCDirector::sharedDirector~~>setProjection; 이거나
아니면
CCDirector::sharedDirector~~>setDepthTest(false);
이거 둘중에 하나인가요?

아니면 혹시 다른 방법을 사용하신건지 궁금합니다^^;;

CCDirector::sharedDirector->setProjection(CCDirectorProjection2D);를 사용했습니다.
