Inspector "Hint" Property

Failed googling...
How can i get this sort of "Hint" property work?

 

Are you asking how to create such a hint in the inspector for a custom script?

 

Jup,
thought its alike [Header("Blah")] or [TextArea] and hoped that i just cant find the command.
Guess its not that simple?

 

I think you need to make a custom editor: https://docs.unity3d.com/Manual/editor-CustomEditors.html

 

oooook avoided it long enough, time to get into that stuff...
Thank you for pushing me to the right direction

 

Yup, has to be done in a custom editor.
For reference, it's the EditorGUILayout.HelpBox method.

 

I have dodged doing hints by using the tooltips on all my public and serialized vars.
