How reliable is ondestroy() function?

Is there a correspondence between start and ondestroy?

You will only almost have a 1:1 correspondence of Start and OnDestroy: The notable exception is if a script component is initially disabled (i.e. you disabled it in edit mode) but its GameObject is enabled, you’ll still get OnDestroy called on the script even if Start wasn’t called (which may be a bug now that I think about it).

Why doesn’t ondestroy work when script is disabled?

The issue with OnDestroy (and OnApplicationQuit fwiw) is it won’t be called if the script is disabled, which can happen if: You call SetActive (false) on the GameObject or any of its parents. You set enabled = false on the script component.
