NGUI 3 Support / Re: NGUI, 4.3 and new Sortyng Layers

« on: January 07, 2014, 10:59:38 AM »

We have to combine SkinnedMeshRenderer with NGUI UIPanels in  Unity 4.3.x. In this case we have to handle the sorting layers in NGUI. Is the following code a correct way to do this?
I used the SortingLayerExposed-Script (https://gist.github.com/nickgravelyn/7460288) to set the SortingLayer for the SkinnedMashRenderer. In NGUI I did the following patch:

In UIPanel.cs I added:

1. 67      public int sortingOrder = 0;
2. 68      public int sortingLayerID = 0;
3.  

In UIDrawCall GetDrawCall (int index, Material mat) I added after:

1. 397       // Create the draw call
2. 398      UIDrawCall drawCall = go.AddComponent<UIDrawCall>();
3. 399      drawCall.baseMaterial = mat;
4. 400      drawCall.renderQueue = UIDrawCall.list.size;
5. 401      drawCall.panel = this;
6.  

the lines

1. 402       drawCall.sortingLayerID = sortingLayerID;
2. 403           drawCall.sortingOrder = sortingOrder;
3.  

In UIDrawCall.cs I added:

1. 43   public int sortingLayerID
2. 44   {
3. 45      get
4. 46      {
5. 47         return mSortingLayerID;
6. 48      }
7. 49      set
8. 50      {
9. 51         if (mSortingLayerID != value)
10. 52         {
11. 53            mSortingLayerID = value;
12. 54            
13. 55            if (mRen != null)
14. 56            {
15. 57               mRen.sortingLayerID = mSortingLayerID;
16. 58               UnityEditor.EditorUtility.SetDirty(gameObject);
17. 59            }
18. 60         }
19. 61      }
20. 62   }
21. 63   int mSortingLayerID;
22. 64
23. 65   public int sortingOrder
24. 66   {
25. 67      get
26. 68      {
27. 69         return mSortingOrder;
28. 70      }
29. 71      set
30. 72      {
31. 73         if (mSortingOrder != value)
32. 74         {
33. 75            mSortingOrder = value;
34. 76            
35. 77            if (mRen != null)
36. 78            {
37. 79               mRen.sortingOrder = mSortingOrder;
38. 80               UnityEditor.EditorUtility.SetDirty(gameObject);
39. 81            }
40. 82         }
41. 83      }
42. 84   }
43. 85   int mSortingOrder;

In public void Set (BetterList<Vector3> verts, BetterList<Vector3> norms, BetterList<Vector4> tans, BetterList<Vector2> uvs, BetterList<Color32> cols) I added after:

1. 363         if (mRen == null)
2. 364         {
3. 365            mRen = gameObject.GetComponent<MeshRenderer>();
4. 366         }
5.  

the lines:

1. 368         if (mRen != null)
2. 369         {
3. 370            mRen.sortingLayerID = sortingLayerID;
4. 371            mRen.sortingOrder = sortingOrder;
5. 372         }

And after:

1. 374         if (mRen == null)
2. 375         {
3. 376            mRen = gameObject.AddComponent<MeshRenderer>();
4.  

the lines:

1. 377            mRen.sortingLayerID = sortingLayerID;
2. 378            mRen.sortingOrder = sortingOrder;
3.  

Finally I added in UIPanelInspector.cs after:

1. 211      if (clipping != UIDrawCall.Clipping.None && !NGUIEditorTools.IsUniform(panel.transform.lossyScale))
2. 212      {
3. 213         EditorGUILayout.HelpBox("Clipped panels must have a uniform scale, or clipping won't work properly!", MessageType.Error);
4. 214        
5. 215         if (GUILayout.Button("Auto-fix"))
6. 216         {
7. 217            NGUIEditorTools.FixUniform(panel.gameObject);
8. 218         }
9. 219      }
10.  

the lines:

1. 221   int newSortingLayerId = EditorGUILayout.IntField("SOL ID", panel.sortingLayerID);
2. 222   if (newSortingLayerId != panel.sortingLayerID)
3. 223    {
4. 224         panel.sortingLayerID = newSortingLayerId;
5. 225         UnityEditor.EditorUtility.SetDirty(panel);
6. 226   }
7. 227
8. 228   int newSortingLayerOrder = EditorGUILayout.IntField("SOL Order", panel.sortingOrder);
9. 229    if (newSortingLayerOrder != panel.sortingOrder)
10. 230   {
11. 231         panel.sortingOrder = newSortingLayerOrder;
12. 232         UnityEditor.EditorUtility.SetDirty(panel);
13. 233    }
14.  
15.
