ScriptableObject in tutorial obviously not MonoBehaviour
Hi there,
I've been trying to follow an official Unity tutorial (though dated from 2018, link here) for flexible UI using ScriptableObjects, it would seem i'm either missing a step or the behaviour of ScriptableObjects since this tutorial was released has changed, in which case the tutorial should be taken down.
We start with the FlexibleUIData class
[CreateAssetMenu(menuName = "Flexible UI Data")]
public class FlexibleUIData : ScriptableObject
{
public Sprite ButtonSprite;
public SpriteState ButtonSpriteState;
}
Which has a flexible UI class which inherits from it
[ExecuteInEditMode()]
public class FlexibleUI : FlexibleUIData
{
public FlexibleUIData skinData;
protected virtual void OnSkinUI()
{
}
public virtual void Awake()
{
OnSkinUI();
}
public virtual void Update()
{
if (Application.isEditor)
{
OnSkinUI();
}
}
}
And then finally our FlexibleUIButton which is what I'm after ultimately.
[RequireComponent(typeof(Button))]
[RequireComponent(typeof(Image))]
public class FlexibleUIButton : FlexibleUI
{
private Image _image;
private Button _button;
protected override void OnSkinUI()
{
base.OnSkinUI();
_image = GetComponent<Image>();
_button = GetComponent<Button>();
_button.transition = Selectable.Transition.SpriteSwap;
_button.targetGraphic = _image;
_image.sprite = skinData.ButtonSprite;
_image.type = Image.Type.Sliced;
_button.spriteState = skinData.ButtonSpriteState;
}
}
Now, the issue is that a ScriptableObject does not contain the GetComponent methods, and also seemingly cannot be added to objects because of this; changing ScriptableObject to a MonoBehaviour throws all manor of null errors, seemingly because we can no longer set up our default skin? 
If there is a new way to do this, is there a tutorial or sample code for that new method, or am I doing something wrong here?
Many thanks, Ben
This turned out to be over-zealous inheriting, FlexibleUI needed to inherit from MonoBehaviour and not FlexibleUIData
