Adding Positions to the Unity OBJImporter

So, I'm trying to dissect the Unity Wiki's .obj Importer. I can see how the whole thing works and runs, but I want the importer to have some other features, and I have been stuck on how to do it. I was just wondering how I would add the .obj file into the Unity scene, since the .obj Importer already loads the file and checks all the contents. http://wiki.unity3d.com/index.php/ObjImporter

I want to add it as a GameObject, but how would I add the .obj file instantly? is there a built in method?

 

Anyone know?

 

ImportFile() seems to return a Mesh. Assign that mesh to a MeshFilter.

 

Could this work then?

Code (CSharp):

1. public void Start() {
2. meshFilter = new MeshFilter();
3. OBJImporter importer = new OBJImporter();
4. GameObject go = new GameObject();
5. meshFilter.mesh = importer.ImportFile(path);
6. meshFilter.transform.Translate(playerObj.x - 100, playerObj.y - 100, playerObj.z);
7. meshFilter.gameObject = go;
8.  
9. }
10.  
11. public void Update() {
12.  if(....) Instantiate(meshFilter.gameObject);
13. }
14.  

If I understand this correctly, this will create a meshFilter, set the meshFilter's mesh to the current path variable that is assigned, creates a base GameObject, sets that to the meshFilter's gameObject, then sets the position of it to my players x-100, y-100, and z axis.

Then the update function checks for something and Creates the current meshFilter gameObject that is assigned to it.

I was thinking of creating a SelectionGrid to find out the path through user input, then assigning everything to the mesh filter. Could this work?

 

So, would this work?

 

Try it.

 

Code (CSharp):

1. using UnityEngine;
2. using System.Collections.Generic;
3. using System.Collections;
4. using System.IO;
5.  
6. public class GUIObjectSelection
7. {
8.  
9.     private OBJImporter importer;
10.     private string[] filePaths;
11.     private int selectionGridInteger;
12.     private MeshFilter meshFilter;
13.     private string filePath = "C:/Program Files(x86)/Steam/SteamApps/common/NanoForge/Models";
14.     private GameObject obj;
15.  
16.     public void Start()
17.     {
18.         importer = new OBJImporter();
19.         filePaths = getFilePaths(filePath);
20.         meshFilter = new MeshFilter();
21.         meshFilter.mesh = importer.ImportFile(filterReturn(selectionGridInteger));
22.         obj = new GameObject();
23.         meshFilter.gameObject = obj;
24.  
25.     }
26.  
27.     public string[] getFilePaths(string path)
28.     {
29.         string[] newFilePaths = Directory.GetFiles(@path, "*.obj", SearchOption.AllDirectories);
30.         return newFilePaths;
31.  
32.     }
33.  
34.    
35.  
36.     public void Update()
37.     {
38.  
39.     }
40.  
41.     public void OnGUI()
42.     {
43.         if (Input.GetKeyDown("O"))
44.         {
45.             GUILayout.BeginVertical("Box");
46.             selectionGridInteger = GUILayout.SelectionGrid(selectionGridInteger, filePaths, 1);
47.             if (GUILayout.Button("Start")) obj = Instantiate(meshFilter.mesh);
48.             GUILayout.EndVertical();
49.         }
50.     }
51.  
52.     public string filterReturn(int selection)
53.     {
54.         return filePaths[selection];
55.     }
56.  
57. }
58.  
59.  

Ok, well I tried this code.

Got some errors:

Assets/Scripts/GUIObjectSelection.cs(23,20): error CS0200: Property or indexer `UnityEngine.Component.gameObject' cannot be assigned to (it is read only)

Assets/Scripts/GUIObjectSelection.cs(29,43): error CS1501: No overload for method `GetFiles' takes `3' arguments

Assets/Scripts/GUIObjectSelection.cs(47,62): error CS0103: The name `Instantiate' does not exist in the current context

 

So, why am I getting these errors?
