Editor.CreateEditor

参数

描述

为targetObject或targetObjects创建自定义编辑器。

默认情况下，会创建一个具有匹配 CustomEditor 属性的适当编辑器。如果指定了 editorType，则会改为创建该类型的编辑器。如果您创建了多个自定义编辑器，并且每个编辑器显示对象的属性不同，则可以使用此方法。如果objects类型不同或未找到合适的编辑器，则返回 NULL。使用此函数创建的编辑器必须使用Object.Destroy或Object.DestroyImmediate显式销毁。

考虑一个用于编辑路点数组的 Transform 的脚本 WaypointPathEditor。

using UnityEditor;
using UnityEngine;
using System.Collections;


[CustomEditor(typeof(WaypointPath))]
public class WaypointPathEditor : Editor
{
    Editor currentTransformEditor;
    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++)
            {
                Transform wayPoint = myWayPath.wayPointArray[i];

                if (wayPoint != null)
                    optionsList[i] = wayPoint.name;
                else
                    optionsList[i] = $"Empty waypoint {(i + 1)}";
            }
        }
    }

    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 && selectedTransform != null)
        {
            currentTransformEditor.OnInspectorGUI ();
        }
    }
}

附加到路点 GameObjects 的脚本

using UnityEngine;
using System.Collections;

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