UNITY3D拓展编辑器 - InspectorEditor（属性编辑器）1

前文：

   本章节会对InspectorEditor（属性编辑器）的创建方式进行叙述.

正文：

  1.代码最终效果

  

 

  2. 架构阐述

  一个InspectorEditor（属性编辑器）产生直接对应着一个继承MonoBehaviour的脚本文件,脚本文件中定义着不同的属性以供InspectorEditor（属性编辑器）去实现。我们可以通过EditorGUILayout/GUILayout来实现InspectorEditor（属性编辑器）界面。

  

  3. EditorGUILayout脚本分析

  EditorGUILayout 是绘制InspectorEditor（属性编辑器）的脚本类，脚本内部方法大致分为两类，一类是：手动布局，另外一类是：组件绘制。

  4. 开始实现切入正题

  4.1 大家都知道拓展器的脚本都需要放置在Editor文件下进行预编译，所以我们也为自己的项目创建一个Editor目录。额外在创建一个Script目录存储脚本文件。

  

  4.2 在Script文件下创建继承自MonoBehaviour的脚本类,维护自定义编辑器属性.有人会问这个类到底用来干什么的,以当下的理解来讲,用于存储编辑器数据用的.下面将我创建的代码贴到下面以供大家参考。

        {
            return m_RoomMaterial;
        }

        set
        {
            m_RoomMaterial = value;
        }
    }

    public float Vale
    {
        get
        {
            return m_Vale;
        }

        set
        {
            m_Vale = value;
        }
    }
}

    private VirtualRoomColor m_RoomColor = VirtualRoomColor.White;
    private VirtualRoomAudioEffect m_RoomEffect = VirtualRoomAudioEffect.Default;
    private VirtualRoomStruct m_LeftWall = new VirtualRoomStruct();

        set { m_RoomSize = value; }
    }

        set { m_RoomColor = value; }
    }

        get { return m_RightWall; }

        set { m_RightWall = value; }
    }

    {
        get { return m_FrontWall; }

        set { m_FrontWall = value; }
    }

    public VirtualRoomStruct BackWall

    }

    public VirtualRoomStruct Floor
    {
        get { return m_Floor; }

        set { m_Floor = value; }
    }

}

4.3 在Editor目录创建我们的InspectorEditor（属性编辑器）脚本文件,并放入以下代码.(具体代码含义见注释)

using System;
using UnityEngine;
using UnityEditor;
using System.Collections;

[CustomEditor(typeof(SR3DVirtualRoom))]
public class SR3DGUIVirtualRoom : Editor
{
    private bool m_GroupState = true; 

    public override void OnInspectorGUI()
    {
        // 房间实例
        SR3DVirtualRoom room = target as SR3DVirtualRoom;
        EditorGUILayout.BeginVertical();

            EditorGUILayout.Space();
            EditorGUILayout.LabelField("Room Name", "VirtualRoom");
            EditorGUILayout.Space();
            room.RoomSize = EditorGUILayout.Vector3Field("Room Size", room.RoomSize);
            EditorGUILayout.Space();
            room.RoomColor = (VirtualRoomColor)EditorGUILayout.EnumPopup("Room Color", room.RoomColor);
            EditorGUILayout.Space();
            room.RoomEffect = (VirtualRoomAudioEffect) EditorGUILayout.EnumPopup("Room Audio Effect", room.RoomEffect);

        EditorGUILayout.EndVertical();

        // 密度、反射设置
        EditorGUILayout.Space();
        m_GroupState = EditorGUILayout.Foldout(m_GroupState, "Virtual Room Struct");
        if (m_GroupState)
        {
            if (Selection.activeTransform)
            {
                EditorGUILayout.BeginVertical();

                    EditorGUILayout.Space();
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("       Left Wall");
                    room.LeftWall.RoomMaterial = (VirtualRoomMaterial)EditorGUILayout.EnumPopup(room.LeftWall.RoomMaterial);
                    room.LeftWall.Vale = EditorGUILayout.Slider(room.LeftWall.Vale, 0, 1);
                    EditorGUILayout.EndHorizontal();

                    EditorGUILayout.Space();
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("       Right Wall");
                    room.RightWall.RoomMaterial = (VirtualRoomMaterial)EditorGUILayout.EnumPopup(room.RightWall.RoomMaterial);
                    room.RightWall.Vale = EditorGUILayout.Slider(room.RightWall.Vale, 0, 1);
                    EditorGUILayout.EndHorizontal();

                    EditorGUILayout.Space();
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("       Front Wall");
                    room.FrontWall.RoomMaterial = (VirtualRoomMaterial)EditorGUILayout.EnumPopup(room.FrontWall.RoomMaterial);
                    room.FrontWall.Vale = EditorGUILayout.Slider(room.FrontWall.Vale, 0, 1);
                    EditorGUILayout.EndHorizontal();

                    EditorGUILayout.Space();
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("       Back Wall");
                    room.BackWall.RoomMaterial = (VirtualRoomMaterial)EditorGUILayout.EnumPopup(room.BackWall.RoomMaterial);
                    room.BackWall.Vale = EditorGUILayout.Slider(room.BackWall.Vale, 0, 1);
                    EditorGUILayout.EndHorizontal();

                    EditorGUILayout.Space();
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("       Ceiling");
                    room.Ceiling.RoomMaterial = (VirtualRoomMaterial)EditorGUILayout.EnumPopup(room.Ceiling.RoomMaterial);
                    room.Ceiling.Vale = EditorGUILayout.Slider(room.Ceiling.Vale, 0, 1);
                    EditorGUILayout.EndHorizontal();

                    EditorGUILayout.Space();
                    EditorGUILayout.BeginHorizontal();
                    EditorGUILayout.PrefixLabel("       Floor");
                    room.Floor.RoomMaterial = (VirtualRoomMaterial)EditorGUILayout.EnumPopup(room.Floor.RoomMaterial);
                    room.Floor.Vale = EditorGUILayout.Slider(room.Floor.Vale, 0, 1);
                    EditorGUILayout.EndHorizontal();

                EditorGUILayout.EndVertical();
            }
        }
        
        if (!Selection.activeTransform)
        {
            m_GroupState = false;
        }
    }
}

4.4 思路整理

  所有的编辑器都可以根据以下思路进行编写，完成代码后返回UNITY3D编辑器重新加载编译后，将脚本挂载到游戏对象中则显示出自定义编辑器内容,下一篇则对序列属性进行讲解,序列化属性是一种更简单的编辑器编写方式，但也要结合当前基础来编写才会更高效！
