Flap Flap

by malanyo

Flap Flap changes how Elytra gliding works on Fabric, with physics tweaks, durability limits and boost blocks for takeoff stations.

FabricServer-side onlyMIT LicenseOpen source1.21.11

What it does

Elytras lose speed quickly when a player flies upward, and Flap Flap adjusts the physics so climbing feels less abrupt. The maximum flying speed is capped, and fireworks extend flight time as usual, except in creative mode. Unbreaking applies longer to Elytras, so the default durability of 432 still allows 7 minutes 12 seconds of gliding. Mending still repairs them with Phantom Membranes.

Blocks such as lava, fire and campfires create updrafts that lift flyers vertically. A passage through an amethyst frame shaped like a portal gives a forward boost, and the vertical updrafts make it possible to build takeoff stations. Elytra Flight is disabled in fluids, including rain.

Flap Flap is server-side only, so players join without installing it. Only the server needs the mod, and Fabric API must be installed beside it. The server runs the mod once to generate its config, and changes to the config take effect after a restart. Files are published for Fabric only, for 1.21.11, under the MIT License, and the source code is open.

Key features

  1. Vertical climb physics

    Upward flight keeps more speed, so climbing does not lose momentum as quickly as vanilla Elytra.

  2. Capped flying speed

    The maximum flying speed is limited, which keeps boosted flight within a set range.

  3. Updraft blocks

    Lava, fire and campfires push flyers upward, and amethyst frames give a forward boost.

  4. Adjusted Elytra durability

    Unbreaking applies for longer, and the default durability still allows roughly seven minutes of gliding.
