虽然回来很累了，但还是小小坚持一下吧，不然真的平时的想法都废了。

在完成初步显示了，就要思考一下游戏逻辑了。

首先把数据先分离出来，其实除掉图形，在游戏面板上就是一堆的数字了，比如0代表红，1代表绿等。

想想dos时代，用数字搞出个俄罗斯方块那样。。

先把数据抽象出来：

using UnityEngine;using System.Collections;using System;/// 
/// FileName: GameData.cs/// Author: Star/// Date: 12/12/16/// Description: class for game data/// 
public class GameData{    public enum DataType    {        Green,        Orange,        Pink    }        private DataType[,] m_Data;    private int m_NumRow;    private int m_NumCol;        public int NumRow    {        get { return m_NumRow; }        set { m_NumRow = value; }    }        public int NumCol    {        get { return m_NumCol; }        set { m_NumCol = value; }    }        public DataType[,] Data    {        get { return m_Data; }        set { m_Data = value; }    }        public GameData (int row, int col)    {        m_Data = new DataType[row, col];        m_NumCol = col;        m_NumRow = row;        Generate();    }        public void Generate()    {//        Debug.Log("length:"+Enum.GetNames(typeof(DataType)).Length);        for (int row = 0; row < NumRow; row++)        {            for (int col = 0; col < NumCol; col++)            {                m_Data[row,col] = (DataType)UnityEngine.Random.Range(0, Enum.GetNames(typeof(DataType)).Length);//                Debug.Log("["+row+","+col+"]"+":"+(int)m_Data[row,col]);            }        }    }        public DataType GetTypeOf(int row, int col)    {        return m_Data[row,col];    }        }

之后写一个简单的移动，目前定的移动方式是，一拖拖动整条方块，只有上下和左右两种情况，我们以第一次在哪个方向上拖动的距离大来定义本次拖动的方向。

代码如下：

using UnityEngine;using System.Collections;/// 
/// FileName: UIManager.cs/// Author: Star/// Date: 12/12/16/// Description: Manager of game UI/// 
public class UIManager : MonoBehaviour {        public GameObject m_ItemPrefab;    public GameObject m_GamePanel;        Vector3 m_TopLeft = Vector3.zero;    Vector3 m_GameBoardTopLeft = Vector3.zero;    Vector3 m_GameBoardBottomRight = Vector3.zero;        float m_LeftPercent = 0.2f;        int NumRow = 10;    int NumCol = 5;        float m_fItemWidth = 0;    float m_fItemHeight = 0;        enum MoveDir    {        None,        UpDown,        LeftRight    }        MoveDir m_curDir = MoveDir.None;        GameData m_GameData = null;    GameObject[,] m_Items;    // Use this for initialization    void Start () {                m_TopLeft = new Vector3(-Screen.width/2, Screen.height/2, 0);        m_GameBoardTopLeft = m_TopLeft + new Vector3(Screen.width * m_LeftPercent, 0, 0);        m_GameBoardBottomRight = new Vector3(Screen.width/2, -Screen.height/2, 0);                m_fItemWidth = Screen.width * (1-m_LeftPercent) / NumCol;        m_fItemHeight = Screen.height / NumRow;                m_GameData = new GameData(NumRow, NumCol);        m_Items = new GameObject[NumRow,NumCol];                InitItemsWith(m_GameData.Data);    }        void InitItemsWith(GameData.DataType[,] data)    {        GameObject go = null;        UISprite img = null;                for (int row = 0; row < NumRow; row++)        {            for (int col = 0; col < NumCol; col++)            {                go = NGUITools.AddChild(m_GamePanel, m_ItemPrefab);                go.transform.localPosition = new Vector3(col * m_fItemWidth + m_fItemWidth/2,                    -row * m_fItemHeight - m_fItemHeight/2, 0) + m_GameBoardTopLeft;                img = go.transform.FindChild("ItemImg").GetComponent
     
      ();                img.gameObject.transform.localScale = new Vector3(m_fItemWidth, m_fItemHeight, 0);                img.spriteName = GetSpriteByType(data[row,col]);                go.name = row + "|" + col;                UIEventListener.Get(go).onPress += OnPressItem;                UIEventListener.Get(go).onDrag += OnDragItem;                m_Items[row,col] = go;            }        }    }        string GetSpriteByType(GameData.DataType type)    {        switch(type)        {        case GameData.DataType.Green:            return "green";        case GameData.DataType.Orange:            return "orange";        case GameData.DataType.Pink:            return "pink";        default:            return "green";        }    }        public void OnPressItem(GameObject go, bool state)    {        string[] pos = go.name.Split('|');        int row = int.Parse(pos[0]);        int col = int.Parse(pos[1]);                Debug.Log("Click:["+row+","+col+"]");        m_curDir = MoveDir.None;    }        public void OnDragItem(GameObject go, Vector2 delta)    {        string[] pos = go.name.Split('|');        int row = int.Parse(pos[0]);        int col = int.Parse(pos[1]);                //Debug.Log("Click:["+row+","+col+"]");                if (m_curDir == MoveDir.None)        {            if (Mathf.Abs(delta.x) > Mathf.Abs(delta.y))            {                m_curDir = MoveDir.LeftRight;            }            else            {                m_curDir = MoveDir.UpDown;            }        }                if (m_curDir == MoveDir.LeftRight)        {            for (int i = 0; i < NumCol; i++)            {                m_Items[row,i].transform.localPosition += new Vector3(delta.x, 0, 0);            }        }        else if (m_curDir == MoveDir.UpDown)        {            for (int j = 0; j < NumRow; j++)            {                m_Items[j,col].transform.localPosition += new Vector3(0, delta.y, 0);            }        }    }        // Update is called once per frame    void Update () {        }}
     

 

最后效果如下：

发现不对劲了吧，嘿嘿，没有裁减，用NUGI的clipPanel吧。

在start里加入如下代码：

UIPanel panel = m_GamePanel.GetComponent
     
      ();panel.clipRange = new Vector4(Screen.width * m_LeftPercent/2, 0, Screen.width * (1-m_LeftPercent), Screen.height);
     

最后效果：

搞定，收工，睡觉了。
