TextMesh Pro Changing the missing glyph character with code

Hi,

How can I change the missing glyph character through code, without manually modifying the TMP Settings asset in the inspector? I would like to change the character depending on the build platform and/or region.

 

I ended up using reflection to resolve this:

Code (CSharp):

1. [MenuItem("Build/Setup TMP Missing Glypth For Current Platform")]
2. public static void SetupTMPMissingGlypthForCurrentPlatform()
3. {
4.     const int MISSING_CHAR_RECTANGLE = 0;
5.     const int MISSING_CHAR_QUESTION_MARK = 63;
6.  
7.     // Get field with reflection
8.     var settings = UnityEditor.AssetDatabase.LoadAssetAtPath<TMPro.TMP_Settings>("Assets/TextMesh Pro/Resources/TMP Settings.asset");
9.     var field = typeof(TMPro.TMP_Settings).GetField("m_missingGlyphCharacter", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
10.  
11.     // Set missing char for current platform
12. #if UNITY_STANDALONE
13.     field.SetValue(settings, MISSING_CHAR_QUESTION_MARK);
14. #else
15.     field.SetValue(settings, MISSING_CHAR_RECTANGLE);
16. #endif
17.  
18.     // Save changes
19.     UnityEditor.AssetDatabase.Refresh();
20.     EditorUtility.SetDirty(settings);
21.     AssetDatabase.SaveAssets();
22. }

 

I added a setter on this property to allow you to control this more easily.

P.S. When I have time, I will do the same for all other properties (where it makes sense) to allow users to change those via scripting.
