Method/function that is called when ScriptableObject is Created?

Questions & Answers
1

Is there some sort of method/function that is called by Unity when creating (right-click, Create) a ScriptableObject? I need the method/function to be called just once when it is created. thanks

ScriptableObjects have OnValidate, just as MonoBehaviours do.

This function runs whenever there is a change to the object’s serialized values which is more often than you’d like, so combine this with a “hasBeenInitialised” type flag to make sure you only run it once.

public class YanfundisScriptableObject : ScriptableObject
{
    [SerializeField, HideInInspector] private bool _hasBeenInitialised = false;

    [Conditional("UNITY_EDITOR")]
    private void OnValidate()
    {
        if (!_hasBeenInitialised)
        {
            // do your initialisation :)
            _hasBeenInitialised = true;
        }
    }
}

Reset() is called on creation and on selecting ‘Reset’ in a ScriptableObject’s context menu.

Since this has been necro-ed, for editor tooling I suggest using an AssetPostProcessor instead: Unity - Scripting API: AssetPostprocessor

Specifically AssetPostProcessor.OnPostprocessAllAssets is a good way to initialise scriptable objects that need something done just once when they’re created/
