모듈:Crafting usage

[보기 | 편집 | 역사 | 캐시 제거]설명문서Jump to code ↴

이 모듈은 {{crafting usage}}를 구현한다.

제작법의 탐색은 "~을(를) 사용하는 제작법"에 분류되는 아이템들을 탐색하여 제작법을 가져온다. (흑마법!)

의존 관계

• 모듈:Crafting

위 모듈에 의해 정의되는 "Recipe using ~" 분류를 탐색하여 어떤 아이템이 해당 재료를 제작재료로 사용하는지를 알아낸다. 따라서 위 모듈이 생성하는 분류 이름에 모듈:Crafting usage의 코드를 맞추어야 한다.

[보기 | 편집 | 역사 | 캐시 제거]위 설명문서는 모듈:Crafting usage/doc에서 왔습니다.
