Selecting game objects in project, and displaying them through script

Hello.

Through scripting, I want to be able to pick up a currently selected game object in my project's hierarchy, and display its infos.

I know that it has to be something like Selection.activeGameObject, but so far, I only made it work in the Start() function. I want it to work any time I select another game object in the project's hierarchy (not in a game UI), but I did not find the solution yet. Can you help me, please?

Thanks.

Actually, I solved my problem after I posted this.

 

Hah, that's a common case. If you explain your problem to random person, then you will find solution. It works even with cats
