To Fly in Survival

This mod gives survival players the ability to fly exactly like in Creative mode, while also removing the usual digging speed penalty that would normally slow you down when flying.

You can turn on fly resource feature that will add a resource bar to the top-left of the screen that would be slowly consumed when you fly and even faster when you boost-fly. It slowly restores on its own and can be quickly restored by laying in bed or fully by sleeping.

Commands:
/fly - toggles fly.
/fly <player name> - toggles fly for a player.
/fly toggleresource - toggles fly resource.
