1 设计背包背景，格子以及物品

背景

2 实现背包物品的创建

1 背景挂的脚本

using UnityEngine.UI;


public class MyCells : MonoBehaviour {

    public GameObject[] cells;//背包格子
    public GameObject equip;//物品
    public Sprite[] sprites;//物品样式
    private int item;//随机数
    private Sprite equidSprite;//随机生成的物品样式

    void Start () {
        
    }
    
    void Update () {
        if (Input.GetKeyDown(KeyCode.Q))
        {
            AddEquips();
        }
    }

    void AddEquips()
    {
        item = Random.Range(0, sprites.Length);
        equidSprite = sprites[item];
        bool isOpen = false;//用来判断格子里是否有物品
        for (int i = 0; i < cells.Length; i++)
        {
            if (cells[i].transform.childCount > 0)//格子里有子物体
            {
                MyEquid me = cells[i].GetComponentInChildren<MyEquid>();
                if (me.image.sprite == equidSprite)
                {
                    isOpen = true;
                    me.Addcount();//让物品的数量加1
                    break;
                }
            }
        }

        if (isOpen == false)
        {
            for (int i = 0; i < cells.Length; i++)
            {
                if (cells[i].transform.childCount == 0)
                {
                    GameObject go = GameObject.Instantiate(equip) as GameObject;
                    go.transform.parent = cells[i].transform;//让创建出的物品成为格子的子物体
                    go.transform.localPosition = Vector3.zero;//让创建出来的物体局部坐标归零
                    Image im = go.GetComponent<Image>();
                    im.sprite = equidSprite;//让创建出来的物体图片变成随机出来的图片
                    break;
                }
            }
        }
    }
}

public class MyEquid : MonoBehaviour {

    public Text text;
    public Image image;
    private int count;

    public void Addcount()
    {
        count++;
        text.text = count + "";
    }
    
}
