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)
