Error with list of lists in custom editor
Sorry for my english ^_^
I have been suffering for 2 days. I could not solve it myself and find it on the forums. Please help!
Ok, there I have a list in which one more list:
using System;
using System.Collections.Generic;
using UnityEngine;
public class GameManager : MonoBehaviour {
public List<Box> Boxes;
}
[Serializable]
public class Boxitem
{
public int id;
public float chance;
}
[Serializable]
public class Box
{
public string name;
public Sprite image;
public int rarity;
public List<Boxitem> Boxitems;
}
Here I display all the variables in the custom editor. And here there are buttons that create a new Box or Boxitem in Box:
using UnityEditor;
using UnityEngine;
[CustomEditor(typeof(GameManager))]
public class GMEditor : Editor
{
private GameManager gm;
public void OnEnable()
{
gm = (GameManager)target;
}
public override void OnInspectorGUI()
{
EditorGUILayout.BeginVertical("box");
foreach (Box obj in gm.Boxes)
{
EditorGUILayout.BeginVertical("box");
obj.name = EditorGUILayout.TextField("Name", obj.name);
obj.image = (Sprite)EditorGUILayout.ObjectField("Image", obj.image, typeof(Sprite), false);
obj.rarity = EditorGUILayout.IntField("Rarity", obj.rarity);
EditorGUILayout.BeginVertical("box");
foreach (Boxitem bobj in obj.Boxitems)
{
bobj.id = EditorGUILayout.IntField("Item ID", bobj.id);
bobj.chance = EditorGUILayout.FloatField("Chance", bobj.chance);
EditorGUILayout.EndVertical();
}
if (GUILayout.Button("Add item"))
{
obj.Boxitems.Add(new Boxitem());
}
EditorGUILayout.EndVertical();
EditorGUILayout.EndVertical();
}
if (GUILayout.Button("Add box"))
{
gm.Boxes.Add(new Box());
}
EditorGUILayout.EndVertical();
}
}
The problem is that when I click on the button to create a box, I get an error and the Boxitem is not created in the box. But if after creating the box, go to any script and change something, then the error fixes. As you can see in the box above there is an item.
