Unity) 달력 만들기 코드 (Make Calendar)

달력 만들기 코드 (Make Calendar)

간단하게 달력을 만드는 코드를 정리 겸 포스팅하게 되었다.

달력을 만드는 코드는 간단하게 DateTime을 활용해서 구현했다.

이전 달과 현재 달을 선택할수 있고, 토요일과 일요일을 구분했다.

 

현재 날짜(22.02.03일)를 기준으로

선택을 못하게 버튼으로 처리를 했고 Text Color를 좀 더 연하게 구성했다.

 

반응형

< Prefab &  Inspector >

Prefab과 Inspector의 속성은 다음과 같다.

OrgNumber를 기준으로 dayNumber를 계산했다.
