JustFly
by mrcrossii
JustFly lets players fly in survival and multiplayer like Creative Mode, with fall damage protection during a short grace period after flight is turned off.
What it does
Double-tapping Space toggles flight on or off. The flying experience is meant to feel close to Creative Mode flight, and chat messages report the current flight status so players know when it changes. Fly speed can be set in the configuration file, and the grace period after landing can be adjusted the same way.
When flight is disabled, a 10-second grace period follows. During that window fall damage is prevented automatically, so a player who drops out of the air to land is protected. The smart protection system activates on landing flight. Because the environment is client and server, both the server and every player need JustFly for the features to work.
Files are published for Fabric and NeoForge for game versions 1.21.4 – 1.21.11, with the latest file for 1.21.11 on each loader. The mod is released under the MIT License and is not open source.
