이 기사에서는 빨간 봉투 비 효과를 얻기 위해 Taobao 및 JD.com을 모방한 HTML5의 예제 코드를 공유합니다. 도움이 필요한 친구들이 참고할 수 있기를 바랍니다.
이 Red Packet Rain 프로젝트는 HTML5 게임 프레임워크인 Phaser를 기반으로 작성되었습니다. 최종 제품은 캔버스이므로 성능이 매우 좋지만 이 프레임워크는 비교적 크고 압축하면 약 700K 정도라고 해야 할까요.
코드 주소 : https://github.com/AmosXu/red-packet-rain
사진 순서대로입니다. , 빨간 봉투 잡기 페이지, 빨간 봉투 열기 페이지, 빨간 봉투 표시 페이지, 이 페이지는 모두 새로 고침 전환 효과와 슈퍼 성능 없이 캔버스에 작성되었습니다.
