Cannot Add Script Derived From UnityEngine.Component To A GameObject

Hi,
I tried to attach a script that derives from UnityEngine.Component to a GameObject, but it's not working. The editor says, that I can only attache scripts that derives from UnityEngine.Monobehaviour. Thought, the official document says it should work.

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

Is it a bug or is the documentation wrong?

Using Version 2017.3

 

I think MonoBehaviour already inherits from Component, so MonoBehaviour is what you want.

 

Well look at the documentation for Component.

Now look at the documentation for MonoBehaviour.

AddComponent<>() accepts anything derived from T:<MonoBehaviour> and T:<Component> is clearly derived from T:<Object>. So basically - do what the message says and give it something derived from MonoBehavior.

 

UnityEngine.Component: "Base class for everything attached to GameObjects."
The only possible way, that I can think of, is to use AddComponent to attach a script to a GameObject.

I know, I can derive from Monobehaviour, but why is it written like that I can derive from Component and add the script to my Gameobject?

 

And Behaviour inherits from Component

 

It literally says right after that

Derive from MonoBehaviour if you want to attach it to a GameObject. Docs.
