说明：在 Scene视图下利用Gizmos线框实现了一个很多个小怪在地图里面随机走动（目前碰到边缘我是让他走回来）

1 网格（新建一个空物体挂test.cs脚本（代码在下面））
2 小怪管理类（空物体挂 MoveMgr.cs）
3 小怪（空物体挂的是 move）

脚本：test.cs

using UnityEngine;using System.Collections;public class test : MonoBehaviour {    [SerializeField]    public int _totalTime = 60;    [SerializeField]    private float _gravity = -30;    [SerializeField]    private AudioClip _bgm;    [SerializeField]    private Sprite _background;    [SerializeField]    private int _totalColumns = 25;    [SerializeField]    private int _totalRows = 10;    public const float GridSize = 1f;    private readonly Color _normalColor = Color.grey;    private readonly Color _selectedColor = Color.yellow;    public int TotalTime    {        get { return _totalTime; }        set { _totalTime = value; }    }    public float Gravity    {        get { return _gravity; }        set { _gravity = value; }    }    public AudioClip Bgm    {        get { return _bgm; }        set { _bgm = value; }    }    public Sprite Background    {        get { return _background; }        set { _background = value; }    }    public int TotalColumns    {        get { return _totalColumns; }        set { _totalColumns = value; }    }    public int TotalRows    {        get { return _totalRows; }        set { _totalRows = value; }    }    public test Instance { get { return this; } }    // Use this for initialization    void Start ()     {    }    // Update is called once per frame    void Update ()    {    }    //绘制外框    private void GridFrameGizmo(int cols, int rows)    {        Gizmos.DrawLine(new Vector3(0, 0, 0), new Vector3(0, rows *        GridSize, 0));        Gizmos.DrawLine(new Vector3(0, 0, 0), new Vector3(cols *        GridSize, 0, 0));        Gizmos.DrawLine(new Vector3(cols * GridSize, 0, 0), new        Vector3(cols * GridSize, rows * GridSize, 0));        Gizmos.DrawLine(new Vector3(0, rows * GridSize, 0), new        Vector3(cols * GridSize, rows * GridSize, 0));    }    //绘制内部的线条    private void GridGizmo(int cols, int rows)    {        for (int i = 1; i < cols; i++)        {            Gizmos.DrawLine(new Vector3(i * GridSize, 0, 0), new Vector3(i            * GridSize, rows * GridSize, 0));        }        for (int j = 1; j < rows; j++)        {            Gizmos.DrawLine(new Vector3(0, j * GridSize, 0), new            Vector3(cols * GridSize, j * GridSize, 0));        }    }    private void OnDrawGizmos()    {        Color oldColor = Gizmos.color;        Matrix4x4 oldMatrix = Gizmos.matrix;        Gizmos.matrix = transform.localToWorldMatrix;        Gizmos.color = _normalColor;        GridGizmo(_totalColumns, _totalRows);        GridFrameGizmo(_totalColumns, _totalRows);        Gizmos.color = oldColor;        Gizmos.matrix = oldMatrix;    }    private void OnDrawGizmosSelected()    {        Color oldColor = Gizmos.color;        Matrix4x4 oldMatrix = Gizmos.matrix;        Gizmos.matrix = transform.localToWorldMatrix;        Gizmos.color = _selectedColor;        GridFrameGizmo(_totalColumns, _totalRows);        Gizmos.color = oldColor;        Gizmos.matrix = oldMatrix;    }    public Vector3 WorldToGridCoordinates(Vector3 point)    {        Vector3 gridPoint = new Vector3(        (int)((point.x - transform.position.x) / GridSize),        (int)((point.y - transform.position.y) / GridSize), 0.0f);        return gridPoint;    }    public Vector3 GridToWorldCoordinates(int col, int row)    {        Vector3 worldPoint = new Vector3(        transform.position.x + (col * GridSize + GridSize / 2.0f),        transform.position.y + (row * GridSize + GridSize / 2.0f),        0.0f);        return worldPoint;    }    public bool IsInsideGridBounds(Vector3 point)    {        float minX = transform.position.x;        float maxX = minX + _totalColumns * GridSize;        float minY = transform.position.y;        float maxY = minY + _totalRows * GridSize;        return (point.x >= minX && point.x <= maxX && point.y >= minY &&        point.y <= maxY);    }    public bool IsInsideGridBounds(int col, int row)    {        return (col >= 0 && col < _totalColumns && row >= 0 && row < _totalRows);    }}

脚本：MoveMgr.cs

using UnityEngine;using System.Collections;public class MoveMgr : MonoBehaviour {    [SerializeField]    public int m_count = 10;    public GameObject prefab;    // Use this for initialization    void Start () {        for (int i = 0; i < m_count; i++)        {            GameObject.Instantiate(prefab);        }    }    // Update is called once per frame    void Update () {    }}

脚本：move.cs

using UnityEngine;using System.Collections;public class move : sixsixsix {    //方向数组 上下左右    private Vector3[] m_direction = { new Vector3(0, 1, 0),                                       new Vector3(0, -1, 0),                                    new Vector3(1, 0, 0),                                    new Vector3(-1, 0, 0)                                 };    //当前启动移动的方向    private Vector3 m_currentDirection = Vector3.zero;    // Use this for initialization    public override void Start () {        base.Start();        this.m_pointX = Random.Range(0, this.m_totalColumns+1);        this.m_pointY = Random.Range(0, this.m_totalRows + 1);        this.transform.localPosition = new Vector3(this.m_pointX,this.m_pointY,0);        m_currentDirection = m_direction[Random.Range(0, 4)];     }    // Update is called once per frame    public override void Update () {        base.Update();    }    //每隔一秒运行    public override void MoveOneSecond()    {        if (m_isOverBoder)        {            //如果越界 让它返回            m_currentDirection = -m_currentDirection;            this.transform.localPosition += m_currentDirection;            //返回后重新选择方向            m_currentDirection = m_direction[Random.Range(0, 4)];        }        this.transform.localPosition += m_currentDirection;    }    //三秒改变一个方向    public override void ThreeSecondContorlMove()    {        if (!m_isOverBoder)        {            m_currentDirection = m_direction[Random.Range(0, 4)];        }    }}

脚本 sixsixsix.cs（这是一个基类简单的封装可能我封装的很垃圾，学习者慢慢封装吧）

using UnityEngine;using System.Collections;public class sixsixsix : MonoBehaviour {    // Use this for initialization    private test m_t;    protected int m_pointX = 0;    protected int m_pointY = 0;    protected int m_totalColumns;    protected int m_totalRows;    [SerializeField]    protected bool m_isOverBoder;    public virtual void Awake()    {        m_t = GameObject.Find("Grid").GetComponent<test>();        m_totalColumns = m_t.TotalColumns;        m_totalRows = m_t.TotalRows;    }    public virtual void Start()    {        StartCoroutine("Move");        StartCoroutine("ControlMove");    }    // Update is called once per frame    public virtual void Update()    {        Vector3 gridCoord = m_t.WorldToGridCoordinates        (transform.position);        transform.position = m_t.GridToWorldCoordinates((int)gridCoord.x, (int)gridCoord.y);    }    //画每一个物体的样子    private void OnDrawGizmos()    {        Color oldColor = Gizmos.color;        Gizmos.color = (m_t.IsInsideGridBounds(transform.        position)) ? Color.green : Color.red;        Gizmos.DrawCube(transform.position, Vector3.one * test.GridSize);        Gizmos.color = oldColor;        //记录是否出界        m_isOverBoder = !m_t.IsInsideGridBounds(transform.position);    }    IEnumerator Move()    {        while (true)        {            yield return new WaitForSeconds(1);            this.MoveOneSecond();        }    }    IEnumerator ControlMove()    {        while (true)        {            yield return new WaitForSeconds(3);            this.ThreeSecondContorlMove();        }    }    public virtual void MoveOneSecond() { }    public virtual void ThreeSecondContorlMove() { }}

学习了Gizmos这个东西至少我工作中没用到我看书中写的主要是用在关卡编辑器上，写上面这个东西我也是随便的一个想法，这里做一下笔记

以上代码都有注释么有的我的另一边学习Gizmos中有提到 Gizmosde 的一些函数，以上基础都是来之《Extending Unity With Editor》,如有错误请告知
