Select from a component's public variables in editor

I know making variables public will display them in editor as a component's properties.

I'd like to be able to set a script as a property of a component, and then be able to view and select from that script's public variables.

For example, I have Script A attached to a GameObject in scene with a public GameObject field which makes a field visible in editor. Using that field, I can reference any other script, say Script B. Upon referencing Script B, all of Script B's public variables would be visible in editor and selectable via drop down menu.

Is there any sort of Serializable call I can make in Script B or Script A to make those variables viewable in editor?

 

This involves a fair bit of editor magic and reflection. But its certainly doable.

You can use the RemoteFloatField and its property drawer from trend.Me as a place to start. Its only set up to accept numerical data types, but it could easily be adapted for your use case.

A working example of what I'd like to happen is seen in the new UI Button component OnClick field. The user select a Game Object the button will act on OnClick, and from there a drop down list of executable methods associated with that Game Object is then shown.

I'd just like to select any game object and then select variables associated with the scripts on that object.

 

That's pretty much what the remote field does in TrendMe.

 

In script you can define an event and expose it in Unity Inspector as so..

Code (CSharp):

1. using UnityEngine.Events;
2.  
3. [System.Serializable]
4. public class OnEvent : UnityEvent { }
5.  
6.  
7. // Expose in your script.
8. [SerializeField] OnEvent myEvent;
