Question Export data from List<> to .json file

I am working on a simple AR 3d scanner project, and as a beginning I am trying to reconstruct a 3d model from a list of recorded point cloud data. I am kind of new to unity scripting and don't actually know how I can convert this list of added point clouds to a .json file to be referenced to later.

So I need the list of vector3 postitions of the point cloud to be saved to a .json file in a persistent storage Location. Can anyone tell me how I can do this? I already have a list of vector3 data.
Any help is greatly appreciated.

 

Unity's got a built in JSON converter, but it's a bit finicky - it can't directly serialize lists or arrays, so you have to stick the list/array inside a serializable class or struct. Here's an example:

Code (csharp):

1.  
2. using System;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. [Serializable]
7. public struct VectorContainer {
8.     public List<Vector3> vectors;
9. }
10.  
11. public class TestScript : MonoBehaviour {
12.  
13.     private void Start() {
14.         var vectorContainer = new VectorContainer();
15.  
16.         // This would be your vectors:
17.         vectorContainer.vectors = new List<Vector3> {
18.             Vector3.back,
19.             Vector3.down,
20.             Vector3.up
21.         };
22.         var str = JsonUtility.ToJson(vectorContainer, true);
23.  
24.         // You'd write them to file instead of just printing them
25.         Debug.Log(str);
26.     }
27. }

 

This might be overkill but i think it will do what you want:
