AntiFlight

Players who gain unauthorized flight through fly hacks, elytra exploits or similar tricks are stopped by server-side checks. Ground support is verified on the server, so a client that claims to be on the ground gains no advantage. Vanilla gliding with rockets stays free unless the movement shows real evidence of an exploit. Ender pearl, chorus fruit and portal teleports reset the reference point rather than being read as flight.

When a player fails a check, the mod corrects their position to the last known valid support rather than pulling them out of the sky, so setbacks stay small and rubber-banding is avoided. An optional hunger mode replaces the setback with a penalty: food drains first, scaling with speed, and an idle hoverer still pays. Health loss only starts once the flight lasts long enough that the player is already starving, and damage ticks slowly enough that landing is always survivable.

The mod is server-side only, so players join without installing anything. The license is the GNU General Public License v3.0 only, and the source code and issue tracker are public. Its files are published for Fabric only, across 17 release versions 1.21 – 26.3, with 1.1.5 for 26.3 as the latest file.
