Unity Editor自定义检视面板

学习了下自定义检视面板的使用，效果图如下：

先是定义一个脚本文件，我们来修饰它的检视面板：

[HelpURL("http://www.baidu.com")]
public class Atr : MonoBehaviour
{
    public int id;
    public string Name;
    [Multiline(5)]
    public string BackStory;

    public float health;
    public float damage;

    public float weaponDamagel, weaponDamage2;
    public string shoeName;
    public int shoeSize;
    public string shoeType;

    [Space(100)]
    [Range(-2,5)]
    public int time;
    void Start ()
    {
        health = 50;
    }
}

然后在根目录的Editor文件夹下定义一个用来修饰上面脚本检视面板的类文件：

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(Atr))]
//需要继承自editor，并且引入UnityEditor程序集
public class LearnInspector : Editor
{
    private Atr atr;
    private bool showWeapons;

    void OnEnable()
    {
        //获取当前自定义的Inspector对象
        atr = (Atr) target;
    }

    //执行该函数来自定义检视面板
    public override void OnInspectorGUI()
    {
        //不写默认是垂直布局
        EditorGUILayout.BeginVertical();

        //空格
        EditorGUILayout.Space();
        EditorGUILayout.Space();

        EditorGUILayout.LabelField("Base Info");
        atr.id = EditorGUILayout.IntField("Atr ID", atr.id);
        atr.Name = EditorGUILayout.TextField("Atr Name", atr.Name);

        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();

        EditorGUILayout.LabelField("Back Story");
        atr.BackStory = EditorGUILayout.TextArea(atr.BackStory, GUILayout.MinHeight(100));

        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();

        atr.health = EditorGUILayout.Slider("Health", atr.health, 0, 100);

        if (atr.health < 20)
        {
            GUI.color = Color.red;
        }
        else if (atr.health>80)
        {
            GUI.color = Color.green;
        }
        else
        {
            GUI.color = Color.grey;
        }

        Rect progressRect = GUILayoutUtility.GetRect(50, 50);

        EditorGUI.ProgressBar(progressRect,atr.health/100.0f,"Health");

        GUI.color = Color.white;

        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();

        atr.damage = EditorGUILayout.Slider("Damage", atr.damage, 0, 20);

        if(atr.damage<10)
        {
            EditorGUILayout.HelpBox("伤害过低",MessageType.Error);
        }
        else if (atr.damage > 15)
        {
            EditorGUILayout.HelpBox("伤害过高",MessageType.Warning);
        }
        else
        {
            EditorGUILayout.HelpBox("伤害适中",MessageType.Info);
        }

        EditorGUILayout.Space();
        EditorGUILayout.Space();
        EditorGUILayout.Space();

        EditorGUILayout.LabelField("Shoe");
        EditorGUILayout.BeginHorizontal();
        EditorGUILayout.LabelField("Name", GUILayout.MaxWidth(50));
        atr.shoeName = EditorGUILayout.TextField(atr.shoeName);
        EditorGUILayout.LabelField("Size", GUILayout.MaxWidth(50));
        atr.shoeSize = EditorGUILayout.IntField(atr.shoeSize); EditorGUILayout.LabelField("Type", GUILayout.MaxWidth(50));
        atr.shoeType = EditorGUILayout.TextField(atr.shoeType);

        EditorGUILayout.EndHorizontal();

        EditorGUILayout.EndVertical();
    }
}

//绘制字段用到的方法

//EditorGUILayout.LabelField（）标签字段
//EditorGUILayout.IntField（） 整数字段
//EditorGUILayout.FloatField（） 浮点数字段
//EditorGUILayout.TextField（） 文本字段
//EditorGUILayout.Vector2Field（） 二维向量字段
//EditorGUILayout.Vector3Field（） 三维向量字段
//EditorGUILayout.Vector4Field（） 四维向量字段

可以看出该修饰类和效果图对应的关系。我们可以方便的定义检视面板来协助游戏的开发调试，让它直观的显示出帮助消息。
