List of lists in Inspector

Hi all,
I have really searched everywhere but without finding answers.
I have to show in inspector a Vector3 list of lists starting from a MonoBehaviour.
I tried adding classes and anyway all the examples found but without succeeding.
I tried

Code (CSharp):

1. public class Point{
2.      public List<Vector3> list;
3. }

and

Code (CSharp):

1. public List<Point> myPoints= new List<List<Point>>();

as found in an example but it raises me error.
Can someone give me a practical example? I do not know what to do anymore.

 

Thats different type, List<Point> vs List<List<Point>>

this seems to work,

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Lister : MonoBehaviour
6. {
7.     public PointList ListOfPointLists = new PointList();
8. }
9.  

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. [System.Serializable]
6. public class Point
7. {
8.     public List<Vector3> list;
9. }
10.  
11. [System.Serializable]
12. public class PointList
13. {
14.     public List<Point> list;
15. }
16.  

 

Thank you very much, it works!
But how should I address the lists?
With

Code (CSharp):

1. ListOfPointLists.list [0].list.Add (new Vector3 (1, 1, 1));

I can insert new Vector3 but must I first initialize a new list of Points?
Currently, the List Size does not change in the Inspector.

 

Yes, I need to add

Code (CSharp):

1. ListOfPointLists.list.Add(new Point());

 

But I still have problems!
If I write

Code (CSharp):

1. ListOfPointLists.list.Add(new Point());
2. ListOfPointLists.list [0].list.Add (new Vector3 (1, 1, 1));

the inspector shows a new list but:
ListOfPointLists.list [0] .list.Add (new Vector3 (1, 1, 1))
returns a reference type not set error if the number of lists in Inspector starts with zero.
The list increases by one but raises the error I said.
If I start with the number of lists set at least one works regularly.
What am I forgetting?

 

Ok, I think I finally found the solution:

Code (CSharp):

1. ListOfPointLists.list.Add(new Point());
2. int index = ListOfPointLists.list.Count - 1;
3. ListOfPointLists.list[index].list = new List<Vector3> ();
4. ListOfPointLists.list[index].list.Add (new Vector3(1,1,1));

This way the list is initialized and accepts the input of the Vector3 value. No errors and the inspector correctly shows the content.
Thanks mgear for your support.

 

I know this is very old but a better way for you to initialize this is to make a constructor inside your Point class :

Code (CSharp):

1. [System.Serializable]public class Point
2. {  
3.     public List<Vector3> list;
4.     public Point()
5.     {
6.         list = new List<Vector3>();
7.     }
8. }

 

How i can remove and element from this type of list..?

 

e.g. you could use

Code (CSharp):

1. ListOfPointLists.list.RemoveAt(*list index*)

to remove a whole list
or

Code (CSharp):

1. ListOfPointLists.list[*list index*].list.RemoveAt(*element position*)

to remove an item from the list

 

I did list of lists and I did it static hereby I can access everywhere it but I can't add a value it give null referance exception error. I equalized the array to new int or string or etc [count] but it didn't. Have you any solution about this? System.Serializable dont let static function is it true? How can I create list of list and access it from everywhere and save last data? Thanks!

 

How can I do them static for access everywhere?

 

To make something static you use "static" keyword. i.e.
public static List<Point> list;

And then to access it you would have to do it this way:
PointList.list[0].Add(something);

 

worked like a charm tysm <3
