Feedback Attribute or trigger for start or domain reload

When the domain reloaded. Sometimes the script that ExecuteInEditmode or ExecuteAlways rely on the variable that was cleared and has to reinit its own state too. And so I think we should have attribute to mark a class or instance function or interface to declare that, after domain reload, this script want to be Start again, or have some Init function to trigger it when domain reload but after script start

Like InitializeOnLoadMethod but on instance level component in the scene

 

The closest think I can find to what you describe is the OnEnable method

 

Yes, but OnEnable also trigger when it just disabled and enabled. I want to have specific OnStart that only trigger just when it start or domain reload

In fact, Start function should trigger on domain reload. But it would be breaking change so it should have attribute or specific function for this

 

I don't see it being too difficult to introduce your own attribute or interface and hook into assembly reload events to initialise anything in active scenes that implement them: https://docs.unity3d.com/ScriptReference/AssemblyReloadEvents.html

 

I already did that but I propose that this should be officially standardized in unity and anyone who want to do this should use the same pattern
