InitializeOnLoad = System.NullReferenceException

Question

 using UnityEngine;
 using UnityEditor;
 
 [InitializeOnLoad]
 
 public class VersionUpdater
 {
     static VersionUpdater()
     {
         GameObject.FindGameObjectWithTag("Version").GetComponent<TextMesh>().text = "v"+PlayerSettings.bundleVersion;
     }
 }

Gives this ugly error:

System.NullReferenceException: at (wrapper managed-to-native) UnityEngine.GameObject:GetComponent (System.Type) at UnityEngine.GameObject.GetComponent[TextMesh] () [0x00000] in :0 at VersionUpdater..cctor () [0x0000b] in /Users/Luke/Desktop/Unity/Unity Projects/Now You're Dead/Now You're Dead/Assets/Editor/VersionUpdater.cs:11 UnityEditor.EditorAssemblies:SetLoadedEditorAssemblies(Assembly[])

It's because you are trying to get an object which doesn't exists at that moment. [InitializeOnLoad] invokes static cctor as soon as possible, i.e. in most cases when Unity starts and no game objects created.

Yeah, you're right. I had to do it on editor play ins$$anonymous$$d… slight shame but I don't know if there was a way around it.
