Question How to check if a property is assigned through the inspector for a gameobject in EditorWindow code.

I have a component attached to a gameobject with following fields.



Now I have an EditorWindow code to check whether, say, the rigidbody field has been assigned some RigidBody in the inspector for that particular gameObject.
How do I do that?

 

this will automatically add the required components if they are not added

https://docs.unity3d.com/ScriptReference/RequireComponent.html

 

I think I couldn't describe my problem well enough.
What I want to know inside of my EditorWindow code is whether a particular field of a component (on a particular gameobject) has been assigned a value in the inspector or not?

I want to create a setup verification script that can tell me that my gameobject is setup correctly before going into Play Mode.

Just like say inside a Monobehaviour I can put the null check to verify whether a value was assigned or not but that will happen when we are in Play Mode.
I want similar check in Edit Mode inside my EditorWindow class.

Hope I was able to describe better this time.

Thanks for your response anyways.

 

you need to use "editor" scripting basically.

https://docs.unity3d.com/ScriptReference/Editor.html

or here

https://docs.unity3d.com/Manual/editor-CustomEditors.html

down the page there is:

Code (CSharp):

1. When you enter Play mode, the GameObject that you attached the script to now orientates itself towards the coordinates you set to the “Look At Point” property. When writing Editor scripts
2. , it’s often useful to make certain scripts execute during Edit mode, while your application is not running. To do this, add the ExecuteInEditMode attribute to the class, like this:

which look like is what you need
