unity中Inspector属性面板的扩展三

扩展自带的主键属性，比如说Main Camera

1.新建C#脚本，命名为CameraEditor

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


[CustomEditor(typeof(Camera))]
public class CameraEditor : Editor {
    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        GUILayout.Label("********以下是扩展选项********");
        if(GUILayout.Button("点击处理"))
        {
            Debug.Log("检测到点击了");
        }
    }

}

需要扩展哪个主键只需要把主键的类型传进去就可以了
