混用ngui和ugui渲染顺序问题

为NGUI panel 添加 sorting layer

接着上一篇文章的问题，看到了老外做的一个补丁，为ngui panel添加sorting layer，我也照着做了一个，这样ngui和unity2d就可以完全融合在一起了，层次关系可以任意设置。

ngui的版本为3.6.8，在其中添加代码：

文件：UIDrawCall.cs 109行左右

[csharp] view
plain copy







/// <summary>

/// Renderer's sorting order, to be used with Unity's 2D system.

/// </summary>

public int sortingOrder

{

get { return (mRenderer != null) ? mRenderer.sortingOrder : 0; }

set { if (mRenderer != null && mRenderer.sortingOrder != value) mRenderer.sortingOrder = value; }

}

// added by Clark

public string sortingLayerName

{

get { return (mRenderer != null) ? mRenderer.sortingLayerName : "default"; }

set

{

if(mRenderer != null && mRenderer.sortingLayerName != value)

{

mRenderer.sortingLayerName = value;

if UNITY_EDITOR

UnityEditor.EditorUtility.SetDirty(gameObject);

endif

}

}

}

// added end by Clark

712行左右

[csharp] view
plain copy







/// <summary>

/// Create a new draw call, reusing an old one if possible.

/// </summary>

static UIDrawCall Create (string name, UIPanel pan, Material mat, Texture tex, Shader shader)

{

UIDrawCall dc = Create(name);

dc.gameObject.layer = pan.cachedGameObject.layer;

dc.baseMaterial = mat;

dc.mainTexture = tex;

dc.shader = shader;

dc.renderQueue = pan.startingRenderQueue;

dc.sortingOrder = pan.sortingOrder;

// added by Clark

dc.sortingLayerName = pan.sortingLayerName;

// added end by Clark

dc.manager = pan;

return dc;

}

文件UIPanel.cs 130行左右

[csharp] view
plain copy







// Clipping rectangle

[HideInInspector][SerializeField] UIDrawCall.Clipping mClipping = UIDrawCall.Clipping.None;

[HideInInspector][SerializeField] Vector4 mClipRange = new Vector4(0f, 0f, 300f, 200f);

[HideInInspector][SerializeField] Vector2 mClipSoftness = new Vector2(4f, 4f);

[HideInInspector][SerializeField] int mDepth = 0;

[HideInInspector][SerializeField] int mSortingOrder = 0;

// added by Clark

[HideInInspector][SerializeField] string mSortingLayerName;

// added end by Clark

252行左右

[csharp] view
plain copy







public int sortingOrder

{

get

{

return mSortingOrder;

}

set

{

if (mSortingOrder != value)

{

mSortingOrder = value;

if UNITY_EDITOR

NGUITools.SetDirty(this);

endif

UpdateDrawCalls();

}

}

}

// added by Clark

public string sortingLayerName

{

get { return mSortingLayerName; }

set

{

if(mSortingLayerName != value)

{

mSortingLayerName = value;

if UNITY_EDITOR

NGUITools.SetDirty(this);

endif

UpdateDrawCalls();

}

}

}

// added end by Clark

1432行左右，在函数UpdateDrawCalls里面

[csharp] view
plain copy







for (int i = 0; i < drawCalls.Count; ++i)

{

UIDrawCall dc = drawCalls[i];

Transform t = dc.cachedTransform;

t.position = pos;

t.rotation = rot;

t.localScale = scale;

dc.renderQueue = (renderQueue == RenderQueue.Explicit) ? startingRenderQueue : startingRenderQueue + i;

dc.alwaysOnScreen = alwaysOnScreen &&

(mClipping == UIDrawCall.Clipping.None || mClipping == UIDrawCall.Clipping.ConstrainButDontClip);

dc.sortingOrder = mSortingOrder;

// added by Clark

dc.sortingLayerName = mSortingLayerName;

// added end by Clark

}

文件UIPanelInspector.cs 9行

[csharp] view
plain copy







using UnityEngine;

using UnityEditor;

using System.Collections.Generic;

// added by Clark

using System;

using System.Reflection;

using UnityEditorInternal;

// added end by Clark

39行左右

[csharp] view
plain copy







UIWidget.Pivot mDragPivot = UIWidget.Pivot.Center;

GUIStyle mStyle0 = null;

GUIStyle mStyle1 = null;

// added by Clark

string[] sortingLayerNames;

// added end by Clark

49行左右

[csharp] view
plain copy







protected override void OnEnable ()

{

base.OnEnable();

mPanel = target as UIPanel;

// added by Clark

sortingLayerNames = GetSortingLayerNames();

// added end by Clark

}

574行左右

[csharp] view
plain copy







GUI.changed = false;

int so = EditorGUILayout.IntField("Sort Order", mPanel.sortingOrder, GUILayout.Width(120f));

if (GUI.changed) mPanel.sortingOrder = so;

// added by Clark

int sortingLayerIndex = GetSortingLayerIndex(mPanel.sortingLayerName);

int newSortingLayerIndex = EditorGUILayout.Popup("Sorting Layer", sortingLayerIndex, sortingLayerNames);

if(sortingLayerIndex != newSortingLayerIndex)

{

mPanel.sortingLayerName = sortingLayerNames[newSortingLayerIndex];

}

// added end by Clark

785行左右，在文件最后

[csharp] view
plain copy







// added by Clark

string[] GetSortingLayerNames()

{

Type t = typeof(InternalEditorUtility);

PropertyInfo prop = t.GetProperty("sortingLayerNames", BindingFlags.Static | BindingFlags.NonPublic);

return (string[])prop.GetValue(null, null);

}

int GetSortingLayerIndex(string layerName)

{

for(int i = 0; i < sortingLayerNames.Length; i++)

{

if(sortingLayerNames[i] == layerName)

{

return i;

}

}

return 0;

}

// added end by Clark

这样，在UIPanel里面就多一个选项sorting layer：



完整的修改好的文件我放到我的资源里面了。
