Custom editor won´t save (Solved)

Hi there, i have been working on a custom editor for the last month. it´s almost done but i have noticed a big issue. i have a few objectfields that i should be able to fill with different gameobjets, so far it works in the scene and when playing the game. however, if i turn the gameobject that contains the Editor script into a prefab. all the objectfields that contains scene objects becomes null, but the objectfields that contains prefabs still has their gameobjects attached. Also to avoid confusion, the problem only happens inside the asset folder and not in the scene. i am still learning about how to write custom editors so it´s probably an noob mistake

Managerscript:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4. using System.Collections.Generic;
5. using System.Linq;
6.  
7. [SerializeField]
8. public class Missionmanager : MonoBehaviour {
9.  
10.     public GameObject Mission_UI,Placement,Pickups,SpecialUnit,RewardPanel;
11.     public RectTransform UIText,unitsUI,BuildingUI,SearchUI,KillUI,EscortUI,ReachUI;
12.     public GameObject UICTRL;
13.     public int curMission;
14.     public bool Build, Search, Kill, Reach, Escort, Random;

79.  
80.         }

i have cutted a few parts of my scripts because they are quite large and no reason to read all
2000 lines of code lol. hope someone clever can help me out

 

hey, problem solved...

 

Hi i am happy you solved your issue , but how did you do that any tip ?

 

Hi, if i remember correctly the issue is that for some reason you can´t have a custom editor with gameobjects as a prefab inside the Asset folder. A workaround for me was to look for the specific gameobjects in the awake method or start method, and then assign them to the fields i needed.

if you need to add specific gameobjects to your custom editor i suggest adding them in the scene instead of inside the asset folder. hope this make sense
