flightSync
by lunixialive
flightSync fixes a bug where an elytra keeps gliding after a player travels through a portal, and it stops the glide when the client receives a dimension change or respawn packet.
What it does
When a player wearing an elytra passes through a portal while gliding, the glide mode can stay active afterward. flightSync stops the elytra gliding automatically once the client receives the dimension change or respawn packet, so the player lands normally in the new dimension. The bug is described as usually occurring when a player is gliding and pearls through a portal.
The fix runs on the client alone, so a server does not need it and players join without a second install. It depends on Fabric API and uses a single mixin with a lightweight configuration. Until a player mounts a boat, minecart, saddled animal or similar entity, the stuck gliding state can persist, and relogging or mounting one of these is the usual workaround that flightSync replaces. The author notes that it is difficult to determine whether server-side performance mods contribute to the issue.
Key features
Automatic glide stop
Gliding ends on its own after a portal transition, so the player does not need to relog or mount an entity.
Dimension change handling
The stop triggers when the client receives a dimension change or respawn packet.
Single mixin fix
The change is made with one mixin and a small configuration file, touching only the portal flight behavior.
Ender pearl portals
The fix also covers gliding players who pass through a portal after throwing an ender pearl.
