Unity---Inspector面板自定义

一. 参数自定义

一个含有成员的类Player

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class Player : MonoBehaviour

{

    public int id;

    public string playerName;

    public string backStory;

    public float health;

    public float damage;

    public float weaponDamage1, weaponDamage2;

    public string shoeName;

    public int shoeSize;

    public string shoeType;

    void Start()

    {

        health = ;

    }

}

写完之后，inspector面板上是这样的：

然后，写一个编辑扩展脚本（写出该脚本即可，不需要做任何操作）：

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEditor;

//CustomEditor(typeof()) 用于关联你要自定义的脚本

[CustomEditor(typeof(Player))]

//必须要让该类继承自Editor,且不需要导入UnityEditor程序集

public class PlayerInspector : Editor

{

    Player player;

    bool showWeapons;

    void OnEnable()

    {

        //获取当前编辑自定义Inspector的对象

        player = (Player)target;

    }

    //执行这一个函数来一个自定义检视面板

    public override void OnInspectorGUI()

    {

        //设置整个界面是以垂直方向来布局

        EditorGUILayout.BeginVertical();

        //空两行

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        //绘制palyer的基本信息

        EditorGUILayout.LabelField("Base Info");

        player.id = EditorGUILayout.IntField("Player ID", player.id);

        player.playerName = EditorGUILayout.TextField("PlayerName", player.playerName);

        //空三行

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        //绘制Player的背景故事

        EditorGUILayout.LabelField("Back Story");

        player.backStory = EditorGUILayout.TextArea(player.backStory, GUILayout.MinHeight());

        //空三行

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        //使用滑块绘制 Player 生命值

        player.health = EditorGUILayout.Slider("Health", player.health, , );

        //根据生命值设置生命条的背景颜色

        if (player.health < )

        {

            GUI.color = Color.red;

        }

        else if (player.health > )

        {

            GUI.color = Color.green;

        }

        else

        {

            GUI.color = Color.gray;

        }

        //指定生命值的宽高

        Rect progressRect = GUILayoutUtility.GetRect(, );

        //绘制生命条

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

        //用此处理，以防上面的颜色变化会影响到下面的颜色变化

        GUI.color = Color.white;

        //空三行

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        //使用滑块绘制伤害值

        player.damage = EditorGUILayout.Slider("Damage", player.damage, , );

        //根据伤害值的大小设置显示的类型和提示语

        if (player.damage < )

        {

            EditorGUILayout.HelpBox("伤害太低了吧！！", MessageType.Error);

        }

        else if (player.damage > )

        {

            EditorGUILayout.HelpBox("伤害有点高啊！！", MessageType.Warning);

        }

        else

        {

            EditorGUILayout.HelpBox("伤害适中！！", MessageType.Info);

        }

        //空三行

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        //设置内容折叠

        showWeapons = EditorGUILayout.Foldout(showWeapons, "Weapons");

        if (showWeapons)

        {

            player.weaponDamage1 = EditorGUILayout.FloatField("Weapon 1 Damage", player.weaponDamage1);

            player.weaponDamage2 = EditorGUILayout.FloatField("Weapon 2 Damage", player.weaponDamage2);

        }

        //空三行

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        EditorGUILayout.Space();

        //绘制鞋子信息

        EditorGUILayout.LabelField("Shoe");

        //以水平方向绘制

        EditorGUILayout.BeginHorizontal();

        EditorGUILayout.LabelField("Name", GUILayout.MaxWidth());

        player.shoeName = EditorGUILayout.TextField(player.shoeName);

        EditorGUILayout.LabelField("Size", GUILayout.MaxWidth());

        player.shoeSize = EditorGUILayout.IntField(player.shoeSize);

        EditorGUILayout.LabelField("Type", GUILayout.MaxWidth());

        player.shoeType = EditorGUILayout.TextField(player.shoeType);

        EditorGUILayout.EndHorizontal();

        EditorGUILayout.EndVertical();

    }

}

写完之后inspector面板上是这样的

通过自定义Inspector视图可以实现很多方便的功能。例如将脚本组件的static变量或者私有变量显示出来，或者实现多参数的联动变化，即修改其中的某个参数，其余参数会随之调整。

二. 编辑时运行

代码：

[ExecuteInEditMode]

public class Test : MonoBehaviour

{

    // Update is called once per frame

    void Update()

    {

        transform.LookAt(Vector3.zero);

    }

}

ExecuteInEditMode表示程序的Update在编辑状态下运行
