About this Mod

Acrophobia

Minecraft mod that aims to nerf flight with elytra, modded creative flight armors and other flight methods.

Features

If you are not touching the ground/liquid/riding a vehicle you get the Fear of Heights effect for a configurable duration. If you land on the ground/liquid/riding a vehicle the effect is removed. If the effect runs out it transforms into a higher level for a longer (configurable) duration. On level II and above every 5 seconds you get affected by Nausea, Wither, and Hunger (levels scale up with fear level). The maximum level is configurable (default V). If heavyArmor is enabled and you have more armor than full diamond (or toughness above 8), the fear jumps instantly to max level.

Configuration

On first run, a config file is created at config/acrophobia.json with:

  • waitDuration: Level I duration in ticks (default 200)
  • fearDuration: Level II+ duration in ticks (default 400)
  • maxLevel: Maximum fear level (default 5)
  • heavyArmor: If true, excess armor jumps to max level (default true)
  • effectsGrounded: If true, Levitation/Slow Falling count as grounded (default true)

Frequently Asked Questions

Acrophobia 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 (1.21.11). You can switch loaders with one click in the panel.

Is Acrophobia compatible with fabric?

Acrophobia officially supports fabric for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Acrophobia – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Acrophobia 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.
