Send Message on Scriptable Object

Unity Engine
1

I have a script which is a Scriptable Object, and I’m trying to use SendMessage in it (to create a tooltip effect). I use this code in other scripts (Mono scripts), but it won’t recognize SendMessage in this context. Can someone help me out with this? Thanks!

if (Event.current.type == EventType.Repaint  GUI.tooltip != lastTooltip)
                {
                    if (lastTooltip != "")
                        SendMessage(lastTooltip + "OnMouseOut", SendMessageOptions.DontRequireReceiver);

                    if (GUI.tooltip != "")
                        SendMessage(GUI.tooltip + "OnMouseOver", SendMessageOptions.DontRequireReceiver);

                    lastTooltip = GUI.tooltip;
                }

P.S. I’ve tried to create an instance of the Scriptable Object, then use “instance.SendMessage”, but that didn’t work.

EDIT: I’ve gotten it to work by simply referencing an existing Monobehaviour:

GUIController GC = Camera.main.GetComponent<GUIController>();

if (Event.current.type == EventType.Repaint  GUI.tooltip != lastTooltip)
                    {
                        if (lastTooltip != "")
                            GC.SendMessage(lastTooltip + "OnMouseOut", SendMessageOptions.DontRequireReceiver);

                        if (GUI.tooltip != "")
                            GC.SendMessage(GUI.tooltip + "OnMouseOver", SendMessageOptions.DontRequireReceiver);

                        lastTooltip = GUI.tooltip;
                    }

It seems like a bit of a hack, but it gets the job done. Any thoughts on a more “proper” way of doing this?

You cannot call any GameObject methods directly from a ScriptableObject(no Get/AddComponent, or message sending). It is simply a different class.
Likewise, no MonoBehaviour callbacks will be called on the Scriptable Objects(OnEnable/Disable/Destroy are there, but they are redefined in the ScriptableObject class).
