Make Shooter Game 3rd person 4.7

Hello, I was wondering if anyone has been able to, or has any input on how to make UE4’s shooter game (Found in the example games) 3rd person? Preferably in Blueprints. I have been following this tutorial (Which is a good one)

But I’m a real noob with C++. Ideally I would like to be able to switch back and forth between 3rd and First person using blueprints. Any input would be fantastic! Thanks in advance!
