Flight Kick Bypass

When a player floats too long on a server, vanilla disconnects them with the multiplayer.disconnect.flying message. Flight Kick Bypass handles that kick path: it finds the top solid collision block below the player's current X and Z position, teleports the player onto it, and resets velocity and fall distance. Afterwards the vanilla kick flow continues, and the server config decides whether the player is kept online after a successful teleport. Both normal player floating and vehicle floating are covered.

The mod is useful where modded blocks, models or collision behavior leave players in positions that repeatedly trigger the vanilla flying check, and where network problems cause similar repeated disconnects. Once a player is kicked again right after reconnecting, an administrator would otherwise have to move that player by hand through server tools. Relocating the player onto a valid block beneath them ahead of the flying kick spares that manual work.

The mod does not grant flight permission and leaves the movement check untouched; its effect is limited to the moment right before the vanilla flying disconnect runs. It runs server-side only, so players join without installing it. It is published for Fabric and NeoForge for 1.21.1 only, and the code is licensed under the GNU General Public License v3.0 or later, so it is open source.
