개요

버튼을 누르면 씬 천이 하는 구현으로 매번 사용하고 있는 SceneController 컴퍼넌트를 소개합니다.

설명

버튼의 UnityEvent 등으로 LoadScene() 등의 함수를 추가해 사용합니다.



품목
설명


ProcessOnAwake
이 컴퍼넌트가 최초로 유효하게 되었을 때에 실행하는 처리

SceneName
대상 장면 이름

Delay
실행하는 데 걸리는 시간



Public 함수
설명


LoadScene()
[Delay]초 후 [SceneName]로 전환

LoadScene(float)
[float]초 후 [SceneName]로 전환

LoadScene(string)
[Delay]초 후 [string]으로 전환

LoadAddScene()
[Delay]초 후 [SceneName] 추가

LoadAddScene(float)
[float]초 후 [SceneName] 추가

LoadAddScene(string)
[Delay]초 후 [string] 추가

UnloadScene()
[Delay]초 후 [SceneName] 파기

UnloadScene(float)
[float]초 후 [SceneName] 파기

UnloadScene(string)
[Delay]초 후 [string] 파기
