Font kerning not serialized?

[ryan]

Looking into a problem with some font spacing today, I noticed that my font prefabs don't have any of the kerning information serialized.  After a little digging, I found that the kerning is stored in a struct, and apparently Unity doesn't support serialization of user-defined structs.  I did this to get the kerning serialized:

1. diff old/Assets/NGUI/Scripts/Internal/BMGlyph.cs new/Assets/NGUI/Scripts/Internal/BMGlyph.cs
2. 16c16,17
3. <       public struct Kerning
4. ---
5. >       [System.Serializable]
6. >       public class Kerning
7. 67,69c68
8. <                               Kerning k = kerning[i];
9. <                               k.amount = amount;
10. <                               kerning[i] = k;
11. ---
12. >                               kerning[i].amount = amount;

Ok, wow! How was this not discovered previously? The kerning information makes fonts look so much more readable. Please put this into the next update!

o_O Interesting...

Any before / after pics of what effect this has?

This is a better modification.

The effects are mostly not noticeable, but with our font certain character combinations ended up a little more crowded than they should have been.  A lowercase "f" followed by an apostrophe is what caused me to investigate.  In the attached example, the spacing between the capital "W" and lowercase "i" is also slightly different, and a little extra space is inserted before the capital "T" without kerning.

Thanks for the modification.

Yeah I guess I overreacted... it is not night/day difference but with some fonts in particular T + e is a really noticeable combination as well.
