cocos2d-x 1.01 ripple, wave, liquid 응용

 

 

 

cocos2d-x openGl10 엔진을 이용한 ripple, wave, liquid 효과 적용, C++로 코딩 한번 해 봄.액션 시퀀스를 사용하지 않고 각 효과 클래스 객체가 릴리즈 될때의 초간격을 이용해 구현. 이유가 있음 초 간격을 잘못 주면 다운...폰 배터리 빼고 다시 켜야함. 이구.. 보니느 스맛뽄이 꾸질꾸질 구형이라 2.13 cocos2d-x는 visual studio 에서만 확인, 물론 안드로이드 자바 랩핑까지만 되는 것만 봄...
