Generic Hashset

So I'm trying to do something to avoid repeating the same code and changing just the object, I tought i could do it like this:

Code:

object getObjectList<T>()
        {
            return UnityEngine.Object.FindObjectsOfType<T>();
        }

But it doesn't work, i never worked with generics before so i need a little hand in here, is there any way i could do something like this?
[DOUBLEPOST=1437517919][/DOUBLEPOST]Edit: I currently use it like this:

Code:

new HashSet<Barricade>(UnityEngine.Object.FindObjectsOfType<Barricade>())

But i don't want to do it for barricades, buildingblocks, traps etc etc, i just want a generic method.

 

Code:

new HashSet<T>(UnityEngine.Object.FindObjectsOfType<T>());

I've tried that before, it wont allow me to use T in FindObjectsOfType, says i cant cast 'T' as 'UnityEngine.Object'.

EDIT: It worked, thanks alot man

 

Yeah, thats all i added and it worked. Will be testing in around 15 mins, this will make everything smaller and cleaner
