About this Mod
A simple mod that adds a /fly command to allow you to fly no matter the gamemode (or not)
Usage
/fly [<players>] [<state>]
If no players are specified the command will target the user.
If no state is specified the command will toggle the flight state of the target.
This will fail if there are multiple targets.

Currently English and Dutch are supported.
If the client does not have the mod installed the language of the server will be used.
(On a dedicated server this is likely English, in a LAN world it is the current language of the host.)

SlashFly server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1-snapshot-10). You can switch loaders with one click in the panel.
Is SlashFly compatible with fabric?
SlashFly officially supports fabric for Minecraft 26.1-snapshot-10, 26.1-snapshot-9, 26.1-snapshot-8. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with SlashFly – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SlashFly consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
