Client Flying

A lightweight client-side Fabric mod that enables controlled flight behavior in Survival and Adventure modes while preventing Elytra conflicts, operating entirely on the client.

Overview

Client Flying allows players to toggle flight in Survival and Adventure modes when not wearing Elytra.

The mod also forces the client to continuously report grounded movement to the server and enables local invulnerability flags. All changes are handled entirely on the client side.

When Elytra is equipped, flight permission is automatically disabled to avoid interference with vanilla glide mechanics.
