카카오 엔진 스크립트 중 상점에서 아이템분류를 해주는 스크립트입니다.

중복이라면 댓글로 남겨주시면 자삭하겠습니다.

* 필요한 것

■ 쇼뿌아이콘

저장 위치 : Graphics / system
파일 이름 : ShopIcon
사이 즈 : 144 x 24

24 x 24 이미지를 다음 순서로 정렬합니다.
아이템, 무기, 방패, 머리, 몸, 장식

KGC 님의 장비 확장 스크립트를 사용하려면
그곳에서 설정한 정렬 오른쪽으로 추가하십시오.
그 때 144px에 맞추기 필요가 없습니다.

ShopIcon.png로 GraphicsSystem에 넣어주세요
