Editor.CreateEditor

参数

描述

为 targetObject 或 targetObjects 创建自定义编辑器。

默认情况下，创建的相应编辑器具有匹配的 CustomEditor 属性。 如果已指定 editorType，则改为创建该类型的编辑器。 如果已创建多个自定义编辑器，其中每个编辑器显示对象的不同属性，请使用此方法。 如果 objects 具有不同的类型或者未找到相应的编辑器，将返回 NULL。

设想一个 WaypointPathEditor 脚本，用于编辑 wayPoint 数组的变换。

using UnityEditor;
using UnityEngine;
using System.Collections;


[CustomEditor(typeof(WaypointPath))]
public class WaypointPathEditor : Editor
{

    Editor currentTransformEditor;
    Transform[] waypoints;
    Transform selectedTransform;
    string[] optionsList;
    int index = 0;
    WaypointPath myWayPath;

    void GetWaypoints()
    {
        myWayPath = target as WaypointPath;

        if (myWayPath.wayPointArray != null)
        {
            optionsList = new string[myWayPath.wayPointArray.Length];

            for (int i = 0; i < optionsList.Length; i++)
            {
                optionsList[i] = myWayPath.wayPointArray[i].name;
            }
        }
    }

    public override void OnInspectorGUI()
    {
        GetWaypoints ();
        DrawDefaultInspector ();
        EditorGUILayout.Space ();
        EditorGUI.BeginChangeCheck ();

        if (optionsList != null)
            index = EditorGUILayout.Popup ("Select Waypoint", index, optionsList);

        if (EditorGUI.EndChangeCheck())
        {
            Editor tmpEditor = null;

            if (index < myWayPath.wayPointArray.Length)
            {
                selectedTransform = myWayPath.wayPointArray[index];

                //Creates an Editor for selected Component from a Popup
                tmpEditor = Editor.CreateEditor(selectedTransform);
            } else {
                selectedTransform = null;
            }

            // If there isn't a Transform currently selected then destroy the existing editor
            if (currentTransformEditor != null)
            {
                DestroyImmediate (currentTransformEditor);
            }

            currentTransformEditor = tmpEditor;
        }

        // Shows the created Editor beneath CustomEditor
        if (currentTransformEditor != null &amp;&amp; selectedTransform != null)
        {
            currentTransformEditor.OnInspectorGUI ();
        }
    }
}

附加到路标 GameObject 的脚本：

using UnityEngine;
using System.Collections;

// Note: this is not an editor script.
public class WaypointPath : MonoBehaviour
{
    public Transform[] wayPointArray;
}
