How to hack/spawn items in minecraft?

Added (1). Like where you can spawn diamonds etc and add enchants (optional) in this video zek trolls a hacker and if you look at the stuff he has how does he get that? I mean then he starts to fly near the end, how do you do this? You definitely can't do this with huzuni, doe he have to bypass anti cheat?

Those are the powers that come from Creative Mode.
On a server, only the admins will have the power to do this.
