so would be creating teleporters like the call of duty franchise for my zombie game i want to create be copyright?.
No. Nobody owns the right to the idea of teleporters.
As long as the teleporter doesnt look exactly the same, it shouldnt be a problem 
At least here in Germany there is not any copyright on game ideas, so here we can create the exact same game as someone else and it’s fine. But I don’t know about the law in other countries.

Note: I’m assuming in live in the US; rules and laws can change country to country.
A copyright is put on your work upon release.
Every work has a copyright to it (just make sure you put the symbol for safety).
What a copyright will protect is YOUR version of a work.
Example:
Think of Space Invaders vs Galaxian.
The copyright on Space Invaders forced Galaxian to choose different colors and sounds.
Namco couldn’t RECREATE (Copy) Space Invaders, but they could create their own version.
The same thing happened to DOOM when it was released.
Think of all the clones.
With that said, a copyright will protect YOUR version of a “teleporter,” but will, of course, not give you the rights to the fictional object of a “teleporter” (as you didn’t create it).
I’m not really sure if this answered your question, though.
I wasn’t sure if you were asking if your game objects will be protected (Yes) or you will hold ownership over the idea (No).
Alternatively, a you could look into a trademark which will protect things such as the name of your game.

I hope this helped.
