1. 정적 스크롤뷰

<버튼 클릭하면 타입과 가격 나오기(가장기본)>

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

public class UIGoldCell : MonoBehaviour
{
    public enum eGoldType
    {
        Tiny,Fistful,Pouch,Box,Chest,Vault
    }
    [SerializeField]
    protected Button btnPrice;
    [SerializeField]
    protected eGoldType goldType;
    [SerializeField]
    protected float price;
    // Start is called before the first frame update
    void Start()
    {
        this.btnPrice.onClick.AddListener(() =>
        {
            Debug.LogFormat("타입:{0}, 가격:{1}", this.goldType, this.price);
        });
        
    }
    
}

전에 할 때는 왜 하는지 잘 모르겠었는데 집에서 천천히 하니까 확실히 이해되는느낌

<Init()을 이용해서 가격과 타입 출력하기>

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

public class UIGoldCell : MonoBehaviour
{
    public enum eGoldType
    {
        Tiny,Fistful,Pouch,Box,Chest,Vault
    }
    [SerializeField]
    protected Button btnPrice;
    [SerializeField]
    protected eGoldType goldType;
    [SerializeField]
    protected float price;
    // Start is called before the first frame update
    public void Init()
    {
        this.btnPrice.onClick.AddListener(() =>
        {
            Debug.LogFormat("타입:{0}, 가격:{1}", this.goldType, this.price);
        });
        
    }
    
}

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

public class UIGoldScrollView : MonoBehaviour
{
    [SerializeField]
    private UIGoldCell[] goldCells;
    // Start is called before the first frame update
    void Start()
    {
        for(int i = 0; i < goldCells.Length; i++)
        {
            UIGoldCell cell = goldCells[i];
            cell.Init();
        }
    }

    
}

결과는 첫번째(Init 사용x 가장기본) 과 같음

init을 왜 하는지 이해되지 않았었는데 scollview 에서 관리하기 위함이라는것을 알게 되었음

버튼 클릭하면 타입과 가격이 나오는 것이 안나왔는데 UIScrollView를 수정하면서 UI.GoldCell의 Init() 함수를 호출하지 않아 안나왔다 -> Start로 바꿈

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

public class UIGoldCell : MonoBehaviour
{
    public enum eGoldType
    {
        Tiny,Fistful,Pouch,Box,Chest,Vault
    }
    [SerializeField]
    protected Button btnPrice;
    [SerializeField]
    protected eGoldType goldType;
    [SerializeField]
    protected float price;

    public eGoldType GoldType
    {
        get
        {
            return this.goldType;
        }
    }
    public float Price
    {
        get
        {
            return this.price;
        }
    }
    // Start is called before the first frame update
    void Start()
    {
        
        this.btnPrice.onClick.AddListener(() =>
        {
            Debug.LogFormat("타입:{0}, 가격:{1}", this.goldType, this.price);
            
        });
        
    }
    
}

ScrollView의 Init에서 상자정보를 출력하고 버튼 출력하면 상자 타입과 가격을 출력

2. 동적 스크롤뷰

public class UIGoldScrollView : MonoBehaviour

    private GameObject uiGoldPrefab;
    [SerializeField]
    private Transform content;
    // Start is called before the first frame update
    public void Init()
    {
        List<GoldData> goldDatas = DataManager.instance.GetGoldDatas();
        
        foreach(GoldData data in goldDatas)

            Debug.LogFormat("<color=yellow>id:{0}</color>,name:{1},type:{2},price:{3},amount:{4}", data.id, data.name, data.type, data.price, data.amount);
            UIGoldCell cell = null;
            GameObject go = Instantiate<GameObject>(this.uiGoldPrefab, content);//content위치에 
            cell = go.GetComponent<UIGoldCell>();
            cell.Init(data);
            
        }
    }
}

이름과 가격은 잘 출력되는데 ui에서는 제대로 표현되지 않음

다른분꺼 블로그 참고하여 했더니 제대로 표현됨

[SerializeField] 
    protected TMP_Text txtPrice;

this.txtPrice.text = string.Format("US${0}", this.price);

왜 그냥 price를 쓰면 안되는지 잘은 이해안되지만 이렇게 추가하니 해결됨

추가로

Debug.LogFormat("이름:{0}, 가격:{1}", this.txtName.text, this.txtPrice);

왜 .text를 쓰는지 궁금해서 txtPrice.text라 안쓰고 그냥 txtprice라고만 치니

이렇게 나옴

+amount도 표시하기(log출력은 X)

ㅎsprite_name이 왜 필요한지 이제 깨달았다 .. ㅎ

계속 this.icon.sprite = atlas.GetSprite(data.sprite_name); 이부분에서 null exception이 나서 몇시간동안 계속 찾았는데 .. Atlas위치가 Resources아래에 있지 않았다 ..
