Detect when a property is changed on a ScriptableObject Asset
I have added a menu command that creates a new ScriptableObject and saves it as an asset. I have also created a MonoBehaviour that has my ScriptableObject as a property. I can add my behaviour to a game object and select my asset using the asset selector. My problem is that when I change a value on my asset, how does my behaviour detect the change and update accordingly?
As a temporary work around I have am storing the old value of the scriptable object properties in my behaviour and then checking each frame to see if they have changed. This is how I detect that the user has edited the behaviour properties. It works, but is starting to get to be a lot of book keeping.
You can use OnValidate() in ScriptableObjects, but Unity forgot to document it for some reason.
According to this, OnValidate kinda sorta works with ScriptabeObject atm. Can you provide a working sample? I can't seem to make this work on my end.

This is awesome, thank you! I wasn't even thinking about just testing it!
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
[CreateAsset$$anonymous$$enu()]
public class ColorScheme : ScriptableObject {
public Color dialogBackground;
public Color sceneTransition;
public void OnValidate() {
Debug.Log(Time.time);
}
}
Thats perfectly working example.
Ahhh yes thank you! I didn't see it as part of the Unity messages recognized by Visual Studio so I was just like ah it doesn't work.. lol so glad it does though!
