[AR Foundation] 자동차 터치 스와이프로 모델링 회전, 스마트폰에서 앱 실행 중에 꺼짐 방지, ScrollView, Content, 자동차 색 변경, 자동차 색 변경 시 위치 안따라오기

shfit + alt

Cell은 이미지

ScrollView에 추가

 

Show Mask Graphic 체크 해제하면 옆에 하얀색 없어짐

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

[RequireComponent(typeof(Button))]
public class CellButton : MonoBehaviour
{
    public enum eColor
    {
        Yellow, Blue, Red, Black, Purple
    }

    [SerializeField] private eColor color;
