NGUI 3 Support / Re: How to apply a shader effect on one sprite?

« on: January 05, 2015, 11:27:01 PM »

See UIShaderSprite for the working copy of this thread.

You can find it on the following github repository:

https://github.com/kimsama/Unity-NGUIExtension

As my experiments, it needs to call panel.RebuildAllDrawCalls() to correctly apply a new shader which is differenct to what NGUI applies in UIDrawCall.UpdateMaterial() call.

Awesome,Thank you so much.

Here is my version of how it could be done. i'm going to use this in my current project.

UIShaderSprite.cs:

1. using UnityEngine;
2. using System.Collections;
3. using System.Collections.Generic;
4.  
5. public class UIShaderSprite : UISprite {
6.         Material mMaterial;
7.         [HideInInspector][SerializeField] Shader mShader;
8.  
9.         // cache materials
10.         static Dictionary<int, Dictionary<int, Material>> atlasMaterials = new Dictionary<int, Dictionary<int, Material>>();
11.  
12.         public override Material material {
13.                 get {
14.                         if (mShader != null) {
15.                                 if (mMaterial == null || mChanged) {
16.                                         Dictionary<int, Material> shaderMaterials;
17.                                         if (!atlasMaterials.TryGetValue(atlas.GetInstanceID(), out shaderMaterials))
18.                                                 atlasMaterials[atlas.GetInstanceID()] = shaderMaterials = new Dictionary<int, Material>();
19.  
20.                                         if (!shaderMaterials.TryGetValue(mShader.GetInstanceID(), out mMaterial) || mMaterial == null)
21.                                                 shaderMaterials[mShader.GetInstanceID()] = mMaterial = new Material(base.material) {shader = mShader};
22.                                 }
23.                                 return mMaterial;
24.                         }
25.                         return base.material;
26.                 }
27.         }
28. }
29.  

Editor/UIShaderSpriteInspector.cs:

1. using UnityEngine;
2. using UnityEditor;
3. using System.Collections;
4.  
5. [CanEditMultipleObjects]
6. [CustomEditor(typeof(UIShaderSprite), true)]
7. public class UIShaderSpriteInspector : UISpriteInspector {
8.  
9.         protected override bool ShouldDrawProperties() {
10.                 NGUIEditorTools.DrawProperty("Shader", serializedObject, "mShader", GUILayout.MinWidth(20f));
11.                 return base.ShouldDrawProperties();
12.         }
13. }
14.  

Thank you for your idea.But I have one question is,whether this way will make the drawcall rise?Becase if there are too many sprites in atlas,there will be too many materials.

« on: October 27, 2014, 05:24:13 AM »

I know how to apply the shader on a material,but I just want to apply a effect on one sprite in atlas.It's there some way to do this?

Misc Archive / How can I get real pixels the font rendering on the screen(use screen coordinat)

« on: October 22, 2014, 10:22:11 PM »

Hi,guys,unfortune,my project using NGUI 2.0.3,now we want to make UILabel support hyperlike.so I modify my UIFont code to implement it like NGUI 3.X.I use mouse position(screen coordinate system) to judge if touch the link.The code like below:
UILabel:
public int GetCharacterIndexAtPosition(Vector3 sceenPos)
{
        return mFont.GetExactCharacterIndex(sceenPos);

         {            
            for(int j = 0;j < verts.size; ++j)
            {
               Vector2 temp = verts.buffer[j];
               temp.y += (yMax_row/2 - charSize/2)*scale.y;

            }
                   
            indexOffset = verts.size;
         }
      }
   }

The code where comment "ext code" is my code.That I want to put the real pixels the font rendering size into mTempVerts,and use GetCharacterIndexAtPosition() to judge the mouse position whether click on hyperlink.But now the value in mTempVerts is wrong,it's not the right value on the screen,example the value in mTempVerts is 32,but on the screen it's more than 10.I think maybe I need do same scale in my value.So how I can to correct my code.

NGUI 3 Support / clip problem in UIPanel with stretch

« on: July 29, 2012, 11:08:26 PM »

hi,our game use 1024*768 resolution in IPAD,that no problem,but now we want to use out layout in android's pad device,there resolution ratio are not same,like 1280*800 1280*600 and so on.We don't want to make many size layouts and images for so many resolution,we just want to stretch them,so I modify the UIRoot.cs like this:

1. manualHeight = Mathf.Max(2, Screen.height);
2.                 //manualWidth = Mathf.Max(2, Screen.width);
3.  
4.                 float size = 2f / manualHeight * ((float)manualHeight / 768);
5.                 float sizeX = (float)Screen.width / 1024 * 2f / manualHeight;
6.                 Vector3 ls = mTrans.localScale;
7.  
8.                 if (!Mathf.Approximately(ls.x, sizeX) ||
9.                         !Mathf.Approximately(ls.y, size) ||
10.                         !Mathf.Approximately(ls.z, size))
11.                 {
12.                         mTrans.localScale = new Vector3(sizeX, size, size);
13.                 }

en,it worked fine as I want,but all my drag list in uipanel are wrong,the cliprect is not correct,their children out the clip rect and still visible,how can I do to make it correct.I use NGUI ver1.82.Waitting for help,thank you.
