Acrophobia
by Midnight-SP
Acrophobia limits how far a player can fly using an elytra or other flight methods, with fear levels that build up over time while airborne.
What it does
Acrophobia is a Fabric mod that targets flight in Minecraft, including elytra and modded creative flight armors. Flight methods accumulate a fear level that grows with time spent in the air. The level duration defaults to 200 ticks at the first stage and 400 ticks from level II onward, and the maximum fear level defaults to 5.
Excess armor jumps are capped at the maximum level by default, and Levitation and Slow Falling are counted as grounded by default, so those effects do not add to the fear level. Every option is set in the mod's configuration. Because it changes gameplay on the server, a server owner decides the rules for everyone who joins.
Acrophobia is published for Fabric only, for 1.20 – 1.21.11 across 19 release versions, and the latest file is 1.0.2+mc1.21.11 for 1.21.11. The code is open source under the MIT License. Every player and the server need a copy of the mod.
Key features
Flight fear levels
Time spent flying raises a fear level, which limits how long a player can stay airborne.
Configurable durations
The duration for the first level and the longer duration from level II onward can each be set in the configuration.
Maximum fear level
A cap on the fear level keeps the effect from growing without limit during long flights.
Grounded effects
Levitation and Slow Falling can be counted as grounded, so they do not raise the fear level.

Use cases
Survival elytra limits
Survival servers can slow down long elytra flights and keep travel tied to the terrain.
Modded flight armor
Mods that add creative flight armor can be limited by the same fear rules, so the restriction applies to those methods too.
Who it’s for: Server owners who want to limit elytra flight and other flight methods, and players who want flight to feel more restricted.
