Changing a *.fontsettings file invalidates all inspector locations where that font is used.

Hi, I have a class I wrote GameFont.cs, which uses an input bitmap to output a Custom Font "MyFont.fontsettings" file. I can then drag this file onto any Font slot in the UI for example. However, when I regen the fontsettings file, every UI which has the Font set on it becomes "Missing (Font)".

I did check the MyFont.fontsettings.meta file, but the GUID isn't changing when MyFont.fontsettings is regenerated... It's almost like it is a GUID problem though... Does anyone know whats going on, and how I can avoid it? I'd like to be able to regen the font and have the UI simply update, rather than go Missing...

I saved off a copy of MyFont.fontsettings and MyFont.fontsettings.meta, regenerated, then compared:

MyFont.fontsettings:
md5sum matches between old and new

MyFont.fontsettings.meta:

diff ../bak/MyFont.fontsettings.meta MyFont.fontsettings.meta

Example C# code showing how to create a Unity Custom Font using source bitmap.

 

check if the Asset exists 1st in ./Assets/... with AssetDatabase.LoadAssetAtPath(..., ...);

if it return null... then AssetDatabase.CreateAsset(...);

else make changes to the already loaded asset.

and then call ...

AssetDatabase.SaveAssets();
AssetDatabase.Refresh();

 

This totally worked. Nice.

Code (CSharp):

1. Font font = AssetDatabase.LoadAssetAtPath<Font>( font_outputNamePath );
2. if (!font)
3. {
4.    font = new Font();
5.    AssetDatabase.CreateAsset( font, font_outputNamePath );
6. }
7. font.name = font_outputName;
8. font.material = material;
9. font.characterInfo = charInfos;
10.  
11. AssetDatabase.SaveAssets();
12. AssetDatabase.Refresh();
