Slash Fly
Slash Fly adds a set of fly commands that players can use in singleplayer and multiplayer, and it is installed on the server only.
What it does
The mod adds a small command set for turning flight on and off. Flight behavior stays consistent when a player changes game mode, and an active flight is not lost when switching modes. A player in creative mode can keep flying even without the slashfly permission, since the mod adds permission-based support for this.
Players join without installing anything, because only the server needs the mod. Slash Fly is open source under the GNU General Public License v3.0 or later. It is published for Fabric, Forge and NeoForge, with files for 26.3 and earlier builds 1.21.8 – 26.2 on the server side.
Recent builds also address a few mining details: a fabric-specific issue with mining speed above ground is fixed, and the penalty to mining speed while flying underwater lasts longer than before.
