今天主要来说下，数据绑定。

之前第一章，我说到 把 资源图 画成格子，你们应该还有印象吧。

那么，当我 知道 格子数据，能否拿到 资源对应的图片呢？

大家先复习一下 第一章，发现很多格子数据 是相同的，有好多个1，好多个2 等等。

所以这里必须要定义一个方向，比如 左上角的1 ，右上角的1，左下角的1，右下角的1.

好，先把资源加载类，继续优化下

using UnityEngine;using System.Collections;public class ResourcesSprite : MonoBehaviour{    void Start()    {        OnAutoTileSave("11", "sea", 0, 3);        OnAutoTileSave("22", "sea", 1, 3);        OnAutoTileSave("33", "sea", 2, 3);        OnSortAutoTile("sea", 3);    }    void Update()    {    }    //对资源图 排序    void OnSortAutoTile(string key, int total = 3)    {        Sprite[, ,] dict = GameModel.getInstance().dictSprite[key];        for (int j = 0; j < 24; j++)        {            Sprite[] sp = new Sprite[total];            for (int i = 0; i < total; i++)            {                sp[i] = dict[i, j / 4, j % 4];            }            int x1 = j / 4;            int y1 = j % 4;            GameModel.getInstance().autoTileSprite.Add(x1 + "," + y1 + "," + key, sp);        }    }    //根据 图片名字，键值名字，当前帧 和 总共帧 保存单例中    void OnAutoTileSave(string pathName, string key, int current, int total)    {        object[] objs = Resources.LoadAll(pathName);        Sprite[, ,] dict;        //是否存在 键值        if (GameModel.getInstance().dictSprite.ContainsKey(key))        {            dict = GameModel.getInstance().dictSprite[key];        }        else        {            dict = new Sprite[total, 6, 4];            GameModel.getInstance().dictSprite.Add(key, dict);        }        int i = 0;        foreach (object obj in objs)        {            Sprite sp = obj as Sprite;            if (sp != null)            {                dict[current, i / 4, i % 4] = sp;                i++;            }        }        GameModel.getInstance().dictSprite[key] = dict;    }  }

大家可以看到，我增加了一个 资源排序的方法，因为 资源图 是 固定的 6*4 格子，应该不可能变，所以我也就写死了。

好，下面看看如何调用这个类。

同样，在昨天 那四个 sprite脚本中增加

using UnityEngine;using System.Collections;public class AutoTileShow : MonoBehaviour{    public int directions;    int i = 0;    private Sprite m_Image;    bool open = true;    Sprite[] sp;    void Start()    {        if (!gameObject.GetComponent
     
      ())        {            m_Image = gameObject.AddComponent
      
       ().sprite;        }        sp = new Sprite[3];//图片数据临时存放    }    float timebattle;    void Update()    {        timebattle -= Time.deltaTime;        if (timebattle <= 0)        {            timebattle = .2f;//闪烁频率            if (i == 3)            {                i = 0;            }            if (open)            {                sp = OnGetAutoTile(directions, 1);                open = false;            }            m_Image = sp[i];            gameObject.GetComponent
       
        ().sprite = m_Image;            i++;        }    }    //通过 方向 权值 获取 对应图像    public Sprite[] OnGetAutoTile(int direction, int weightNumber, string key = "sea")    {        Sprite[] map = { };        ArrayList arr = new ArrayList();        switch (weightNumber)        {            case 1:                arr.Add(0 + "," + 0 + "," + "sea");                arr.Add(1 + "," + 0 + "," + "sea");                arr.Add(0 + "," + 1 + "," + "sea");                arr.Add(1 + "," + 1 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            case 2:                arr.Add(0 + "," + 0 + "," + "sea");                arr.Add(1 + "," + 0 + "," + "sea");                arr.Add(0 + "," + 1 + "," + "sea");                arr.Add(1 + "," + 1 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            case 3:                arr.Add(0 + "," + 2 + "," + "sea");                arr.Add(1 + "," + 2 + "," + "sea");                arr.Add(0 + "," + 3 + "," + "sea");                arr.Add(1 + "," + 3 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            case 4:                arr.Add(2 + "," + 0 + "," + "sea");                arr.Add(5 + "," + 0 + "," + "sea");                arr.Add(2 + "," + 3 + "," + "sea");                arr.Add(5 + "," + 3 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            case 5:                arr.Add(2 + "," + 1 + "," + "sea");                arr.Add(5 + "," + 1 + "," + "sea");                arr.Add(2 + "," + 2 + "," + "sea");                arr.Add(5 + "," + 2 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            case 6:                arr.Add(3 + "," + 0 + "," + "sea");                arr.Add(4 + "," + 0 + "," + "sea");                arr.Add(3 + "," + 3 + "," + "sea");                arr.Add(4 + "," + 3 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            case 7:                arr.Add(3 + "," + 1 + "," + "sea");                arr.Add(4 + "," + 1 + "," + "sea");                arr.Add(3 + "," + 2 + "," + "sea");                arr.Add(4 + "," + 2 + "," + "sea");                map = OnDirectionAutoTile(direction, key, arr);                break;            default: break;        }        return map;    }    public Sprite[] OnDirectionAutoTile(int direction, string key, ArrayList arr)    {        Sprite[] mapTile = new Sprite[3];        mapTile = GameModel.getInstance().autoTileSprite[arr[direction - 1].ToString()];        return mapTile;        /***        switch (direction)        {            case 1://左上                 mapTile = GameModel.getInstance().autoTileSprite[arr[0].ToString()];                break;            case 2://左下                mapTile = GameModel.getInstance().autoTileSprite[1 + "," + 0 + "," + key];                break;            case 3://右上                mapTile = GameModel.getInstance().autoTileSprite[0 + "," + 1 + "," + key];                break;            case 4://右下                mapTile = GameModel.getInstance().autoTileSprite[1 + "," + 1 + "," + key];                break;            default: break;        }         * **/    }}
       
      
     

增加后，我们在u3d界面中，看到一个方向变量。

我们把 四个图，按照左上左下右上右下 1234，对应起来，大家也可以看看这个脚本，有部分注释的，也是这么定义的。

在

void Update() 中，我们运行  sp = OnGetAutoTile(directions, 1);

注意，这个1 就是 权值，也就是 绑定格子的数据值。

我们可以看到 动画状态的 图，如下。因为 是1 的格子，要求四个方向。

 注：OnGetAutoTile方法 写的不是很好，因为我还没找到 规律来优化它，不过反正 只有1-7 这几种，先讲究下吧。

好了，今天先说道这里，下一节是  权值检测，很重要的一章哦
