# AntiFly<\/p>\n
<\/p>\n
Lightweight Paper + Fabric **flight-control plugin** by CevAPI.<\/p>\n
AntiFly is **not a full anti-cheat**.
\nIt exists for one purpose only: **to block flight and extreme movement exploits**.<\/p>\n
Only the following are checked:
\n– Unauthorized flight
\n– Excessive movement speed (ground, air, water)
\n– Elytra speed, stall, and slowdown behavior (optional)
\n– Vehicle flight while preserving normal mount behavior, downhill movement, and genuine falling<\/p>\n
Nothing else is monitored or restricted.
\nNo combat checks. No scaffolding checks. No packet analysis. No behavior profiling.<\/p>\n
Designed specifically for **anarchy and semi-anarchy servers** that want to stop flight hacks without policing gameplay.<\/p>\n
## Platforms

\n– Fabric: 1.21.11 (mojmap, requires Fabric Loader 0.18.1 and Fabric API 0.141.1+1.21.11)<\/p>\n

\n– `\/antifly set` shows all current settings.
\n– `\/antifly set
\n– `\/antifly unexempt
\n– Default ground limits:
\n – `groundSpeedWalking=0.49`
\n – `groundSpeedMounted=0.750`
\n– Vehicle fall tuning defaults:
\n – `vehicleFallMinDescent=-0.04`
\n – `vehicleFallMaxHorizontal=0.40`
\n – `vehicleFallTicksMax=60`
\n– Legacy `groundSpeed` remains accepted as an alias of `groundSpeedWalking`.
\n– Fence\/wall top collisions are treated as valid ground support.
\n– Horse and other mount jumps have extra vehicle-air grace before flight is blocked.<\/p>\n
\nAntiFly can compare the running version against Modrinth project `antiflight` and alert ops\/admins if the server is outdated.<\/p>\n
\n– `\/antifly status` performs a live check.
\n– A startup check also runs and warns ops\/admins when outdated.<\/p>\n
