Dynamic Fonts v2.6.0

[Nicki]

When the characters exceed the font texture size, the font texture size is resized and I think all labels need to refresh at that point, since the texture coordinates for each character then change. I'm not sure the 2.6.0 version does this, but I haven't dug into it yet.

[Ferazel]

Yeah, I don't have 2.6 yet (standard license). From my understanding of dynamic fonts, an element in NGUI needs to be responsible for updating all of the UILabel's texture coordinates when Font.textureRebuildCallback is called by the UnityEngine.Font object. The problem is that every UILabel can't register for this as it is a delegate instead of an event. So maybe the UIFont, if set to be a dynamic font, will dispatch it's own event that the UILabels will listen if they use the dynamic font? (just a suggestion)

Try this... in UIFont, add the following function:

1. void OnFontChanged ()
2. {
3.         UILabel[] labels = Object.FindObjectsOfType(typeof(UILabel)) as UILabel[];
4.  
5.         for (int i = 0, imax = labels.Length; i < imax; ++i)
6.         {
7.                 UILabel lbl = labels[i];
8.                 if (lbl.font == this) lbl.MarkAsChanged();
9.         }
10. }

Then change UIFont's Print() function, changing this line (inside #if !UNITY_3_5 block):

1. if (dynamic) mDynamicFont.RequestCharactersInTexture(text, mDynamicFontSize, mDynamicFontStyle);

to this:

1. if (dynamic)
2. {
3.         mDynamicFont.textureRebuildCallback = OnFontChanged;
4.         mDynamicFont.RequestCharactersInTexture(text, mDynamicFontSize, mDynamicFontStyle);
5.         mDynamicFont.textureRebuildCallback = null;
6. }

If what ArenMook suggested doesn't work, create an example project/scene and post it.

[ArenMook]

Careful posting example scenes. If you post an example, make sure NGUI source isn't a part of it.

Soo... did my snipplet fix the issue? I need to know whether to add this change to the repository for 2.6.1 or not.

[jeldrez]

Sorry, I'll try it tonight and let you know how it was.

[jeldrez]

It didn't work.

I created a scene with a dynamic font.
Then I did a Label and duplicated.
Finally I did a script keybinding some keys with different texts and the text got corrupted with Q and W key, but got fixed with R.

-UIRoot
--UICamera
---UIAnchor
----UIPanel
-----UILabel 1 <text = UNO> (This label has the script)
-----UILabel 2 <text = DOS> (This label get corrupted)

The font texture was 256x256 px.

1. using UnityEngine;
2. using System.Collections;
3.  
4.  
5. public class SRC_DynamicFontTest : MonoBehaviour
6. {
7.    void Update ()
8.    {
9.       if (Input.GetKeyDown(KeyCode.Q))
10.         {
11.             UILabel lbl = GetComponent<UILabel>();
12.             lbl.text = "@$$^34567784561!!!!!!!!!/lkasjflkajsdlñfkj lñaksfj lkasdf lkasdjflkñvjkKLLÑKSDJLKFJLÑKSJDFLKÑJSDDFLÑKJ";
13.         }
14.       if (Input.GetKeyDown(KeyCode.W))
15.         {
16.             UILabel lbl = GetComponent<UILabel>();
17.             lbl.text = "12345566778899000";
18.         }
19.       if (Input.GetKeyDown(KeyCode.E))
20.         {
21.             UILabel lbl = GetComponent<UILabel>();
22.             lbl.text = ")O()=?#($()#?=KJASLKÑDJÑLKASJDÑLKASJD,mv,mv";
23.         }
24.       if (Input.GetKeyDown(KeyCode.R))
25.         {
26.             UILabel lbl = GetComponent<UILabel>();
27.             lbl.text = "ABCDEFGHIJKLMNÑOPQRSTUVWXYZ!#$%%&&/(()=?'-_:;,M<>";
28.         }
29.    }
30. }
31.

Careful posting example scenes. If you post an example, make sure NGUI source isn't a part of it.

An asset bundle which contains just the scene and associated test script would work best. No NGUI source and contains the example.

Hello! I've tested dynamic font of v2.6.0. It is wonderful and very useful to our project.
For some reason, I must use two different shaders for two dynamic fonts in our project. So I writte another shader and create a different material. I found changing the material of the dynamic font was not allowed.

Could you give me some advice?

[ArenMook]

@jeldrez: thanks, that code helped. 2.6.1 has the fix.

@maoguo.zhang: Why not? You can change it on the UIFont prefab.

[jeldrez]

Thanks Aren.
I will try new version ASAP.

[maoguo.zhang]

@maoguo.zhang: Why not? You can change it on the UIFont prefab.

I've tried this many times and I believe that my approach is right. My Unity is V4.1.2.


UIFont.cs
if (isDynamic)
{
   if (mMat != null) mMat.mainTexture = mDynamicFont.material.mainTexture;
   return mDynamicFont.material;
}

I haven't found where you assign mDynamicFont.material.

I just updated 2.6.1, thanks for lot of work

UI Label Works fine. but when I Created UIInput, looks working only Alphabetic Language input while runtime.

is it?

[ArenMook]

Dynamic font only changes the visualization of the font, so if input doesn't work with it for some reason, chances are standard font won't work either. Does it? Make sure the TTF you chosen actually has the glyphs. Most fonts don't have asian glyphs in them.
