이제는 Phaser 프레임 워크에서 HTML5를 사용하여 "2048" 게임을 할 차례입니다.
트윈과 애니메이션을 만드는 것은 매우 쉽습니다. 그래서 여기에 "2048" 게임이 있습니다:
WASD 키로 플레이하고 2048 또는 그 이상으로가보십시오 !!
소스 코드를 보기 전에 흰색 PNG 이미지 만 사용하고 게임 필드 값을 1 차원 배열에 저장하고 있음을 기억하십시오.
이 스크립트를 공부하면 다음 10 가지 원칙을 배우게됩니다.
* 그래픽 애셋로드
* 스프라이트 만들기
* 텍스트를 작성하고 스타일을 지정
* 독립형 Sprite 또는 기존 Sprite의 자식으로 Sprite를 스테이지에 추가하고 제거
* 그룹 만들기
* 그룹을 통해 정렬 및 반복
* 키보드 입력 처리
* 트윈을 사용하여 애니메이션 만들기
* 콜백 관리
* 스프라이트에 색상 필터 적용
